Scraper conveyor malfunction prevention and resolution measures

In the design according to working conditions, a reasonable choice of scraper chain safety factor, which selected the appropriate scraper ring chain, link chain size and style,

at the time of purchase, you should use-proven, has a good reputation comply with relevant quality standards, prohibited the use of substandard

Cell scraper chain, conditional circumstances, the best on the scraper chain necessary tests. Manufacturing enterprises to cope with ring chain, link chain using surface

peening, high load pre-stretching strengthening process, increase its surface residual stress and prevent micro-crack propagation; strengthening ring chain,

Link chain material quality control, both considering its strength, the elongation should be considered, and then through the composite toughening process, grain refinement to

organize and optimize the mechanical properties; improved chain manufacturing process, in particular to avoid the chain link in contact with the inner circular surface at the

straight edge damage, as the transitionmine conveyors

Smooth, and the inner width dimension control link on which the error range to reduce stress concentration where, slow crack occurrence; use of anti-corrosion treatment process,

improve the corrosion resistance of the scraper chain fatigue strength.industrial belt conveyor

Scraper conveyor failure analysis and solutions

Scraper conveyor longwall face is the main transportation equipment, its work properly or not, for the entire coal mine production safety plays a vital role. The scraper chain

scraper conveyor is the main component, is an important traction mechanism, which consists of scraper ring chain, link chain three

Parts, there are statistics show that approximately scraper scraper chain conveyor fault 40% of the total number of failures, therefore, improve the quality of scraper chain

scraper conveyor, prolong life, shaker will help reduce operational accident rate improve the reliability of mining equipment, helping to increase yields face

. Scraper scraper chain conveyor for failure causes and solutions are analyzed and discussed, has a very important practical significance.spiral conveyor
1 fault types and causes
(1) scraper damage
Mostly bent blade damage, excessive wear, a few cracking phenomenon. Its main causes are: laying chute does not meet the design requirements, beyond the requirements of the

bending angle; chute poor bonding at the interface, causing local deformation conveyor chute large lump or waste rock, etc. in operation

Suddenly being squeezed, the blade subject to greater impact; when the adjacent blade spacing exceeds the design requirements, the long-running load on the blade overrun.
(2) on the scraper chain off the sprocket
Scraper chain and sprocket normally not engaged, there called "jump teeth" phenomenon. Its main causes are: head and nose transition groove bending angle is too large; nose slot

plate uneven transition; sprocket badly worn or bite into the debris; linear shaker two chains elastic inconsistent; scraperindustrial conveyor

Severe skew or the spacing is too large.
(3) in the scraper chain coming out of the chute
Its main causes are: scraper conveyor does not meet the design requirements when laying tile laying straight, but convex concave, excessive bending; scraper or chute badly worn,

the blade and chute gap is too large; Coordinate rotation vibration sieve two chains of varying lengths, uneven force; blade deformation is too

Degree bend away from the scraper chain chain shortening; scraper chain pretension is not enough, the shearer cutting machine at the end of the scraper, the scraper chain load

increases, chain link elongation increased at the end of the machine cause heap chain, making the scraper easily disengaged from the chute.
(4) damage to the link chain
In the current domestic ring chain increased reliability in the case, the link chain ring chain fatigue life compared with a big gap, in actual use, the entire link chain became

weaker scraper chain link. It is mainly in the form of damage to the fracture, and its main causes are: long

Under alternating between pulsating loads, well below the breaking force of the water products, the occurrence of fatigue failure; connecting bolt or pin fall off, unable to

replenish, leading to uneven force uniform or inability to force; when used in vertical ring , unilateral severe wear on the teeth, or arc tooth link chain if not more

Change, prone to fracture; card chain, will have a greater dynamic loads and impact loads, combined with scraper chain velocity fluctuations, scraper chain running smoothly so

poor, so that the link chain breakage; Manufacturing Quality poor, not up to standard requirements, low hardness, or appear to be easy to wear

Stress concentration points where fatigue crack, resulting in insufficient strength.
(5) ring-strand breaks
In theory, the use of a variety of scraper conveyor chain ring should be in accordance with standard C-level chain of production, and its breaking load is approximately scraper

can withstand tension nearly 10 times larger safety factor, should not be scission accident, but it and the actual use failure rate greater this

A case does not match, its causes are mainly: manufacturing quality up to standard requirements, material and heat treatment, but off; withstand prolonged alternating pulsating

loads, far below the level of breaking force, the occurrence of fatigue failure, fracture generally chain link arc portion and a straight portion connected

Take place; chain in operation with the chute, sprockets, cargo and other contacts to friction wear, weaken links section, resulting in reduced strength, wear is mainly

manifested in the straight portion of the outer chain ring, circular outer and inner part 3 two parts; chain ring is underground water, corrosion, rust

, Peeling, the cross-section decreases, the intensity decreases; scraper chains to fall into the iron and other occurrence card chain, the chain tension exceeds the allowable

value is pulled off; blade pitch more than twice the required distance when running to the head office is , the chain tension, so that no Bengqi scraper chain, not

Slide the blade slot, but also with the next scraper chain Bengqi with pear head unloading coal board interference occurs card chain, resulting in chain scission; chain

pretension inadequate and too loose, easy to form a heap chain, resulting scraper the tank, the phenomenon occurs card chain; chain tensioner force the Ambassador chain too

tight, increasing the chain's early photos

Force, accelerated wear of the chain and shorten the life of the card in the event there is no cushion to chain; chain in the case of full or overloaded, frequent starting, so

that the chain withstand dynamic tension than the ultimate strength; two chain tightness inconsistent, so that the load is concentrated in the more compact

One chain, thereby exceeding the ultimate strength.

Bent pipe belt conveyor design points

    Better than the common pipe belt conveyor belt conveyor can be notable feature is a small turning radius, thereby reducing the contour can not be used in geographically

universal belt or require multiple transfer points in the case optional pipe belt conveyor. Since the output pipe band

Send conveyor belt idlers around completely bound, so when compared with the general conveyor deviation phenomenon does not occur. Pipe belt conveyor in the horizontal and

vertical surfaces can be bent, can also bend on both sides, the abolition of transfer points, from the side, above or below through

Existing plant equipment and other obstacles, the conveyor belt has just passed the transition period began after the formation of tube bending, bending must be reached before heavy duty conveyor

the completion of the discharge roller transition section. The transition conveyor ends must be linear.
    Pipe diameter, usually bending radius, bending conveyor type and use of the decision. Is recommended to use the standard minimum radius of curvature in the horizontal or

recesses, the fabric band of the core tube 300 times the diameter, steel cord belt should be 700 times the diameter of the tube; but if the "S" shape,

Convex curved and the concave curved or horizontal integrated occurs, the minimum radius of the core fabric band is 400 times the diameter of the pipe, steel cord belt should be

800 times the diameter of the tube; convex curved in the horizontal bending and at the same time the presence of the minimum radius of the core fabric tube with a diameter of Telescoping conveyors

500 times, steel cord belt

Should be 900 times the diameter of the pipe. Foregoing is only general. Typically, the radius of the final decision, depending on the particular conveyor engineers static,

dynamic tension bending conditions and the types used in the General considerations.

Its pitch pipe belt conveyor idler design points

    When the pipe belt conveyor lines running with no vertical or horizontal bent, upper stroke (or pipe belt conveyor carrying side) at the bottom of three roller conveyor and

materials to withstand the weight of the top three roller conveyor into a tube shape to maintain. When a vertical conveyor and

Horizontal bent portion, the other around the conveyor idler roller bearing may be, and the rest to maintain the conveyor roller tube shape. Next trip (ie, the return pipe belt

conveyor) is the same. Next trip or return conveyor to maintain tube shape manipulation, rather than the generic beltscrew conveyor

That the use of flat-shaped conveyor belt, in order to ensure the same structure and size of load side guide belts curved section through a vertical or horizontal.
    Around the roller conveyor is often called circular tube to keep the roller (PSK roller). Idlers diameter and spacing of the size of the pipe belt conveyor and the

transportation of materials decision. Because after a pipe stiffness, the conveyor belt sag meet the requirements of the case, compared with the general conveyor

, Roller spacing is relatively large. Polygon composed of idlers idler roller panel can be installed on both sides of the belt clip in order to avoid running into the gap

between the rollers causing the accident.Pipe conveyor
The end of the conveyor transition (from the flat-belt conveyor belt rolled into tube-shaped), with similar general conveyor, conveyor belt by a different groove angle of roller

group support. Here, through the guide chute of the conveyor load, to ensure that the material added near the longitudinal centerline of the belt, which will help lose

Conveyor belt running, charging plates located under the center of the roller conveyor can absorb shock loads loaded materials. At the beginning of the tube-shaped with a

special set of rollers, arranged by the 12 do not overlap two hexagonal rollers components. 12-gon idlers surrounded the tube-shaped than

Using a standard hexagon idlers closer round, able to withstand very high loads seal pressure. In addition to these idlers, but also uses a special set of guide rollers, the

conveyor belt roll together in front to hold the side to below the other side. The rollers on the installation of the first

Polygon front roller group to eliminate belt edge wear, and closed lap belt correctly.
    Idler alignment and proper loading of the pipe belt conveyor stability and plays a key role in guiding. In a general-purpose conveyor structure, roller frame alignment in

the horizontal and vertical plane, for the correct orientation conveyor belt, complete run is very important, and the use of self-aligning roller

To adjust the incorrect orientation or conveyor deviation. Because pipe conveyor belt is driven around each side of the guide roller, conveyor functions and overcome by bending

at the center conveyor deviation problems. In the pipe belt conveyor is running, you can still adjust the conveyor idlers ride

Take part in the load side as far as possible in the top. However, in fact, mainly to stabilize and maintain their lap belt portion at or near the upper position the weight of

the material being conveyed. 75% of tube cross-sectional area of ​​the center of gravity of the belt material to maintain proper dynamic performance. In

A return or no-load side of the lap belt portion is located below the tube-shaped, so that the weight of the lap on the return to maintain proper dynamic performance.

Pipe Conveyor Belt design elements

    For pipe conveyor belt conveyor and general similar, but also used in the design of some of the important technologies. Rigid and flexible as required, to use a special

skeleton structure. Conveyor must have rigidity through the roller group so as to establish and maintain the circular tube.

At the same time, it must have a certain flexibility, to ensure conveyor belt through the transition section, through the feed zone in the line and rolled into a planar circular

tube running through the drum unloading. This fabric layer may be added between the belt rubber layer to meet.flexible conveyor
    In order to ensure a good seal overlapping portion, thereby preventing leakage of the material, to reduce the rigidity of the belt edge. Further, the upper and lower layer

to control the thickness and curing times, increase the natural tendency of a tube-shaped belt capacity.
For long pipe conveyor, steel cord conveyor structure can also be used at this time, in the upper and lower rope covered with a layer of landscape fabric. Like fabric conveyor

belt structure, as in the fabric and a layer of rubber between the ropes. For emergency repairs, you can temporarily use

Metal joints or replaced with an ordinary belt, until you can make long-term maintenance.
General conveyor belt does not have the required rigidity and flexibility, will produce permanent results with a core layer, fatigue, or other unpredictable problems. But the

advantage is that ordinary conveyor simple structure, low cost, low price, and sometimes can also be used as a substitute for the conveyor pipe. In the pass

When the belt conveyor, belt conveyor pipe conveyor belt and ordinary life are actually the same.powered roller conveyor
Pipe conveyor belt cleaning device and used in the same general belt conveyor, single and multi-blade scraper belt and rotating brush cleaner and air cleaner section can be

applied.
Pipe Conveyor Belt can be specially manufactured, so for conveying hot material. In particular, consideration must be selected belt size and the belt surface temperature of the

material, very hot conveyor belt surface will have a significant impact on the life.

broken shaft gearhead

Belt conveyor gear reducer occur at off-axis high-speed shaft. The most common is the use of a reducer of the first stage bevel gear shaft perpendicular to the high speed shaft.

Occurs off-axis for two main reasons.


1 reducer high speed shaft design strength is not enough



This situation generally occurs in the shaft shoulder because here there fillet, prone to fatigue damage, such as rounded corners make the gear is too small in a short period of

time broken shaft. After the broken shaft fracture usually flush. This happens should be replaced or modified gear reducer design.flexible conveyor


2 high-speed shaft misalignment



Motor shaft and reducer speed shaft misalignment causes the input shaft when increased radial load, increase the bending axis, long-term operation will occur off-axis

phenomenon. In the installation and maintenance of its location should be carefully adjusted to ensure that two concentric shafts. In most cases do not occur off the motor shaft

Axis, which is due to the motor shaft 45 steel materials are generally, relatively coarse motor shaft, stress concentration is better, so that the motor axis is usually not

break.


3 pairs in case of broken motor drive shaft



Dual motor drive is a drive rollers in a unified reducer and two equipped with two motors. High-speed shaft of the gear unit design or selection margin is small compared prone

to the phenomenon of broken shaft. Belt conveyor drive past without using hydraulic devices such situations are more prone to coincidence, because the two TaipowerMetal detector for food

Machine startup and runtime speed synchronization and the force balance is difficult to guarantee. Now, most have been used off-axis hydraulic coincidence is less common

phenomenon, but use should pay attention to the amount of fuel can not be a coincidence is too much, so it has a torque limiting function and progress coincidental's life.

How to install and maintain belt conveyors

A belt conveyor installation: Installation generally carried out according to the following stages:

1) Install belt conveyor rack rack rack installation is started from scratch, and then install the sections sequentially intermediate frame, the final installation of the

tailstock. Before installing the rack, the first full length of the conveyor pulling the central line, due to the central line to keep the conveyor belt in a straight line is

An important prerequisite for normal operation, so when you install the rack sections, should be aligned to the center line, but also put on airs leveling the rack on the

central line of the promised error per meter captain of ± 0.1mm. But the length of the conveyor frame on the central error should not exceed 35mm. When all the single

Install and to identify the section can then be connected to each block.

2) Install the driver when the device is mounted drive unit, must pay attention to the belt conveyor belt conveyor drive shaft and the vertical center line of the drive roller

conveyor width and the center of the center line coincides with the axis of the shaft line reducer parallel. Also, all shafts and rollers

Should be leveling. Axis horizontal error, according to the width of the conveyor, agreed to within the range of 0.5-1.5mm. Driving means installed at the same time, the tail

wheel, etc. can be mounted tensioning device, the tensioning device of the axis of the drum, should the belt conveyor perpendicular to the center line.

3) mounted in a rack rollers, gear and tensioning device after installation, you can install the upper and lower idler roller frame, so that the belt has a slow change to the

curved arc, bending roll cage segment prop prop pitch as normal roller frame pitch 1/2 to 1/3. Idler installation, you should make it light and flexible rotation

Fast.mine conveyors

4) belt conveyor belt in order to ensure the final pinpoint idlers and rollers are always in the center of online operation, installation rollers, racks and rollers when

Must meet the following requirements:

(A) all necessary roller line up parallel to each other and keep the horizontal level.
(2) all rollers arranged in rows parallel to each other.
(3) required linear frame supporting structure, and to keep the horizontal level. To this end, the drive roller and roller frame installed, should be the center of the conveyor

line and level for final alignment.
4) and then fixed on the basis of the rack or floor. After a fixed belt conveyors can be fitted to the loading and unloading devices.
5) Let hanged hanging conveyor belt, the first shop in the strip conveyor idlers load segment, the Wai hold after the drive roller, and then deposited in the heavy segment on

roller. Let hanging strips of use 0.5-1.5t hand winch. Connecting strip in tension, should roll tensioning device

Move cylinder limit position of the car and screw tensioning device To pull the gear shift direction; while picking up tight vertical move to the top of the drum to make the

device. In previous belt tension should be installed reducer and electric motor, inclined conveying confidential installed brakes. Belt Conveyor

After installation, the need for idling test machine.Airport conveyor

In the idling test machine, pay attention to whether the running belt deviation phenomenon, driven sector operating temperature, roller operation flow of the cleaning device and

the guide plate in contact with the belt surface rigor, etc., while make the necessary adjustments, the components are normal before they can

Performed with a load test machine running. If using spiral tensioning device, with load test machine, but also once again its tightness adjustment.



Second, the belt conveyor maintenance:



(A), starting and stopping the conveyor should generally be in the premise of no-load start. By installing several units in the conveyor belt should be used when you can lock

the starter to the control room through a certain order to start and stop. In addition, in order to prevent unexpected accidents, each conveyor

Machine should be set in place to start or stop buttons can be individually Renyiyitai repose. To prevent the belt for some reason are longitudinal tear, when the conveyor

length exceeds 30m, the length along the conveyor should distance intervals (eg 25-30m) to install a stop button

.




 (Two), in order to ensure reliable operation of belt conveyors, the most important is to detect and eliminate possible failures. Staff must always observe this manipulation of

the work of transport, such as abnormal should timely manner. Mechanical inspections and checks of workers should be any need to stay

Or components intended situation, it is very important. For example, a roller, does not seem very important, but a high-speed conveyor belt worn materials may soon put its shell

worn out, thrown a blade, the blade could gravely damage an expensive belt. Trained

Exercise or experienced workers working staff can discover imminent accident and take preventive measures. Belt conveyor belt conveyor in the whole capital in accounting for a

large proportion of proportionality. In order to reduce replacement and maintenance of conveyor expense, must face up on the manipulation of staff and maintenance

Staff for the operation and maintenance of conveyor knowledge training.

Chip conveyor Introduction

Generated during machining scrap iron collection, handling and coolant separation processing, precision, performance, and quality has a great influence, especially in recent

years, in response to global environmental trends, the industrial sector has also improved the work environment very face, so moving iron metal processing line

Transportation device to play a commensurate important functions.
    Iron handling equipment mainstream Chip Conveyors, Chip conveyor itself does not display features that are needed with lathes, machining centers with machine tool

peripherals, so be sure to match the size and shape of machinery; Again sometimes not necessarily alone, but also must comply with several

Taiwan machinery be dealt with the situation, so we need to change the delivery conveyor system and the size and shape of iron mostly different, so a wide range of conveyors is

not surprising.Airport conveyor
    Swarf handling and processing equipment needs due to machine tools (iron), automotive (after stamping scrap) of the market economy in the doldrums, which also caught plight.

Therefore industry is attempting to actively challenge the position to open up new markets and to restore weak demand dilemma.
     Chip conveyor main models are: 1. Scraper conveyor; 2. Chain plate conveyor; 3 screw conveyor; 4 push rod conveyor; 5. Magnetic conveyors; 6 more bucket conveyor; 7.

vibratory conveyors. Others are still in the air compressor of the air inhaled iron and handling automatic move

Transportation systems, tubular conveyors, conveyors and other filtration models.
     Machine tools more diverse, the associated conveyor demand Acres complex. Requirements from the beginning of the chip handling and processing equipment, high productive

forces, to now focus on the composite, space saving, miniaturization and system and so the direction of sophistication.
    In addition, the 1-speed, high-performance processing of aluminum, the resulting large number of chips, the cooling efficiency of the treatment liquid;

(2) low price competition;


3 faces of varying shape non-chip processing;


4 the separation of chips and coolant treatment;pallet conveyor


5 such as ease of maintenance,


Also the current development issues facing the conveyor.
Chip conveyor generally based on the performance of stand-alone promotion based, but there are also required to supplement departmental equipment performance, with its

systematic modular stand-alone functions presented by this trend, is already in the cooling device Chip conveyor and systematic crushing device incorporated into a single

device, but

Yes, at low cost, space-saving features such as improved, there are still a lot of space.
    In this, in order to correspond to a large number of machines under high speed and coolant used for the separation of justice, and therefore requires a conveyor can handle

both iron and coolant, as well as the development of systems for handling the case very much. In addition, in order to be able to recycle the coolant,

Development have also been put into mesh precision filtration equipment Chip conveyor.
     Machine tool and automotive industries due to the economic slowdown continues, so that the cooling and chip processing related equipment has continued to slow down demand.

Demanders on the purchase of new aircraft programs rarely, it touches increase in maintenance in this environment, manufacturers have Product development efforts in the chip and

coolant

Separation of coolant treatment and environmental and other related topics
   Machine tool orders gradually reduced, but the company can handle non-produced chips and cooling homework varying conveyor unit sales have continued to grow. Aircraft types

regardless of chip shape (long, short, etc.), materials (steel, aluminum etc.) can be done deal, especially combined with the cutting of aluminum castings

Treatment, could be the need for high filtration precision and high pressure cooling treatment assignments, and its position in the filter has a powerful automatic reverse

washing apparatus, therefore commensurate convenient maintenance.

Conveyor industry

Conveyor line in a certain material handling machinery continuous feed of material, also known as the continuous conveyor. Conveyor can be horizontal, inclined and vertical

In the transportation process while completing a number of process manipulation, so widely used.
Can be a single conveyor can also be composed of multiple components or other transportation equipment horizontal or inclined conveyor system to meet the different needs are

arranged in the form of homework line.roller chain conveyor



Conveyor trends



① inheritance to large-scale development. Large transmission capacity, including large-scale, large single length and large transmission angle and other aspects. Hydraulic

conveyor length reached 440 km or more. Belt conveyor length of nearly 15 km alone and has been thrown by the number of units consisting Contact AB

Two of the "conveyor belt road." Many countries are exploring a long interval, large capacity continuous transport of materials improved conveyor structure.



② to expand the use of the conveyor. Developments in high temperature, low temperature, under the premise there is erosion, radioactive, flammable substances in the work

environment, as well as capable of delivering fiery, explosive, Pellet, sticky material conveyor.



③ the conveyor structure contentment automated material handling system to control stand-alone asked for. As used in automated sorting post office parcel trolley conveyor

Belt conveyor Common Fault Analysis

As a bulk material conveyor belt transport machinery is widely used in terminals, power plants, metallurgy, food and other industries. In the purchase, design, manufacture,

installation and use of belt conveyor device length of some of the new users that they do not always understand. This article from the user point of view, analysis and

explanation

Belt conveyor equipment common fault causes and treatment.
Elevator conveyor


1 belt conveyor belt deviation handling



Belt conveyor belt deviation runtime is the most common faults, pay attention to the dimensional accuracy of installation and daily maintenance. There are several reasons for

deviation, to be based on the difference between handling different reasons.



1.1 Adjust belt conveyor roller bearing group



Throughout the middle of the belt conveyor idlers deviation, adjust the position to adjust the deviation; idlers in the manufacture of both sides of the mounting holes are

worked into holes in order to make adjustments. Belt deflection which side which side idlers forward direction toward the belt forward or backward the other side

. Belt upward direction of deviation is lower roller group should be at the left, the upper roller group moved to the right place.curve conveyor



1.2 Installation aligning belt conveyor idlers



Spherical roller group has a variety of types, such as intermediate shaft type, four-link, vertical roller, etc., is the use of block or roller rolling direction in the

horizontal plane blocked or automatically generate horizontal thrust to the heart of the belt to adjust the belt deviation purposes. The total length of the belt conveyor

generally shorter or leather

Two-way conveyor belt runs using this method is relatively fair, because the shorter belt conveyor deviation more easily and not easily adjusted.



1.3 Adjust the belt conveyor drive roller and bend pulley position



Drive roller and bend pulley belt deviation adjustment is to adjust the important part. Since at least a belt conveyor rollers 2 to 5, all the rollers must be perpendicular to

the mounting position the longitudinal direction of the conveyor belt center line, will occur if the skew is too large deviation. The adjustment method

And adjustment of roller group similar. For the head drum as the drum belt deviation to the right, the right of the bearing should be moved forward, the belt deviation to the

left of the drum, the left bearing housing should be moved forward, also the corresponding Move the left or right side of the bearing housings after setback

.



1.4 Belt conveyor tensioning adjustment at



Belt tension is adjusted at the conveyor belt deviation adjustment a very important part. Hammer at the upper two tensioning idler pulley in addition to other than perpendicular

to the longitudinal direction of the belt should be perpendicular to the vertical line of gravity, which is to ensure its axis horizontal center line.



1.5 Belt conveyor transfer points at the location of the belt deviation blanking effect



Reprint of materials at the point blanking position on the belt of the deviation has a very big impact, especially in the two belt conveyor in the horizontal plane perpendicular

to the projection of a greater impact. Usually reproduced points should be considered down two belt conveyor relative height. The relative height of the lower horizontal

velocity component of the material

The greater the impact on the lower side of the belt is greater, while the material is difficult to center. The cross section of the material on the belt deflection, the

ultimate cause belt deviation.



1.6 Bidirectional adjustment of running conveyor belt deviation



Bidirectional operation to adjust the belt conveyor belt deviation deviation than the one-way conveyor belt adjustment relative to a lot of problems, adjustment should be

adjusted in detail a certain direction, and then adjust the other direction. Adjust the belt to carefully observe the movement direction of the relationship with the deviation

trend,

Be adjusted individually.
2 scattering material conveyor belt



Caesar feed belt conveyor is a common topic, reason is multifaceted. To strengthen the daily care and maintenance.



2.1 reprinted scattering material at the point of



Reprinted point spread mainly in the fall hopper feed, guide trough, etc.. If severe overload belt conveyor, belt conveyor guide trough backgauge rubber apron damaged steel

guide trough at design time far away from the belt so that the material is relatively long rubber apron out of guide trough.



2.2 The concave section of scattering material when vacant belt



Concave section belt interval when the radius of curvature smaller concave segment will generate vacant belt, then the belt into a trough situation changes, the belt has left

the trough idlers, generally groove angle becomes smaller, so that the material spread out department. Therefore, as far as possible in the design phase should use a larger

concave

Segment radius of curvature to prevent such situations from occurring.



2.3 when the scattering material deviation



When Caesar feed belt deviation is due to both edges of the belt height at run time changes, while high, while the other side is low, the low side of the material from spreading

out, processing method is to adjust the belt deviation.



3 belt conveyor abnormal noise



The driving belt is running, drive rollers and bend rollers and idlers in an abnormal when abnormal noise, abnormal noise can be determined according to equipment failure.



3.1 eccentric roller severe noise



Belt conveyor idlers run often occurs when abnormal noise, accompanied by periodic vibrations. Especially the return roller, because greater length, since the major noise is

relatively large. Noise occurs for two main reasons why. First, the manufacturing of seamless steel pipe wall thickness of roller uneven production

Students larger centrifugal force. The second is in the processing center and the outer ends of the bearing hole circle center deviation is large, so that the centrifugal force

is too large.



3.2 Coupling two different mind-axis noise



High end of the drive unit between motor and reducer coupling or coupling with brake wheel issued by the abnormal noise, which has been associated with the same frequency as the

motor rolling vibration. This noise should occur in a timely manner the position of the motor reducer to be adjusted to avoid deceleration

Input shaft fracture.

Conveyor History:
Chinese ancient high drum water overturned cars and mentioning, is the modern scraper bucket elevators and conveyors prototype; 17th century, began to use aircraft
Empty cableway transport bulk materials; 19th century, various modern structures conveyor has emerged.
1868, in the UK there has been belt; 1887, in the United States appeared screw conveyor; 1905, appeared in Switzerland steel belt conveyor; 1906, in the United Kingdom and

Germany appeared inertia conveyor. Thereafter, conveyors manufactured by mechanical, electrical, chemicalFlat belt conveyor

And metallurgical industries impact of technological advances, and constantly improve gradually from inside to complete the delivery of the workshop, the development completed

within the enterprise, between enterprises and even between cities material handling, mechanized and automated material handling systems become an indispensable component.
Classification of the conveyor
Conveyor according to whether the pulling elements generally be classified
A conveyor having a traction member generally include traction, bearing components, drive means, tensioning means for redirecting means and the support parts. Tractor parts used

to pass traction, can be used conveyor, drag chain or rope; Holds material bearing member to have the hopper, bracket, or

Spreader, etc.; drive to the conveyor to power, generally consists of motor, reducer and brake (stopper) and other components; tensioning devices generally have two kinds of

screw and a hammer, can maintain a certain tension pulling element and sag in order to ensure the normal operation of the conveyor; support for Order

Traction prop pieces or carrying member, can be idlers, rollers, etc.
A conveyor having a traction member structure is characterized by: the material to be transported to the traction member mounted on the bearing member are joined together, or in

directly mounted on the pulling element (such as belt), the pulling element or chain around both of the rollers connected to form load transportation of materials, including

branches and not transported

The material being a non load branch closed loop, continuous motion using the traction member conveying materials.
Such a wide range of conveyors, the main belt conveyors, slat conveyors, trolley conveyors, escalators, moving walkways, scraper conveyor, buried scraper conveyor, bucket

conveyor, bucket elevator , overhead conveyors and overhead lifts and so on.
Conveyor without pulling element different structure and composition, working member for transporting the material is not the same. Their structure is characterized by: the use

of rotational movement of the work member or reciprocating motion, or by the medium flowing in a pipe conveying the material forward. For example, the roller

Conveyor working member of a series of rollers, the roller rotates to transport materials; screw conveyor working member of the spiral, spiral chute rotates in order to push the

material along the trough; vibrating conveyor working member of material groove, trough placed reciprocated to convey

One of the materials.
Conveyor will be toward the future large-scale development, to expand the scope, automatic sorting of materials, reduce energy consumption, reduce pollution and other aspects of

development.
Large transmission capacity, including large-scale, large single length and large transmission angle and other aspects. The length of the hydraulic conveyor belt has reached

more than 440 km length of nearly 15 km of single, and has appeared composed by a number of Taiwan Contact B two places "belt conveyor path." Not

Few countries are exploring long-distance, large capacity continuous transport of materials better conveyor structure. Expand the use of the conveyor, is developing in high

temperature, low temperature conditions, corrosive, radioactive, flammable substances in the work environment, as well as capable of delivering fiery, explosive

, Easy to agglomerate viscous material conveyor
Development trend towards the development of the conveyor are: ① continue to large-scale development. Large transmission capacity, including large-scale, large single length

and large transmission angle and other aspects. Hydraulic conveyor length reached 440 km or more. Belt conveyor length of nearly 15 km single,

And has appeared composed by a number of Taiwan Contact B two places "belt conveyor path." Many countries are exploring long-distance, large-capacity transport of materials

better continuous conveyor structure. ② to expand the use of the conveyor. Developments in high temperature, low temperature, corrosive, radioactive

Sex, flammable substances in the work environment, as well as capable of delivering fiery, explosive, Pellet, sticky material conveyor. ③ the conveyor structure to meet the

automated material handling system to control stand-alone asked for. As used in automated sorting post office parcel trolley conveyor

Sorting machine should be able to meet the requirements of such action. ④ reduce energy consumption in order to save energy, the field of conveyor technology has become an

important aspect of research. Has one ton material handling energy consumed by one kilometer conveyor selection as one important indicator. ⑤ reduce all kinds of conveyors

Generated during operation of dust, noise and emissions.

Bucket elevators Common Cause analysis and treatment programs

     Hopper with bucket elevator is usually canvas belt. Canvas belt and tape prone to tearing, sometimes with tape and chains. The combined effect of various failures. This is

one of the most serious fault. General hopper and the hopper with a deviation most likely caused by the process of shedding a tear hopper

. Should be timely and comprehensive identification of reasons for troubleshooting. In addition, the material is mixed with a sharp edge of the foreign body, will also split

hopper with planning. Therefore, the production, it should be installed in the inlet or magnet wire mesh to prevent large objects have fallen into the base, effectively prevent

the occurrence of such phenomena. Production period

, The current form of a set of effective control measures. Often caused by improper operation bucket elevators current is too high, resulting in the phenomenon of the device is check weighers

not working properly, not only to the large increase in the workload of field personnel, but also affect production. After a summary of the operator and practices from time to

time

.

Bucket elevators opportunities to the general question about the following aspects:

     1, because the use of a chain drive. Sprockets will wear, when used for some time. Need for timely replacement sprocket.
     2, sprocket slipping. Users can adjust the hammer lever tensioning device, or there is the case off the chain. Tensioning both automatically and can adhere to a constant

tension, to prevent slippage and from chain.belt conveyor manufacturer
     3, the device during use to maintain a constant voltage. You can add auxiliary equipment such as electrical control box, in order to avoid excessive current or voltage

instability burning motor. Both can be easily controlled bucket elevator operation, stable voltage and current can also play a role.
    4, hopper with skid
     Device is the use of the hopper with the first round of the friction torque between the drive shaft for material hopper elevator belt tension is not enough. Should be

immediately shut down, will result in the hopper with skid. At this time. Adjusting belt tensioning device to tighten the hopper. If you can not make the hopper belt tensioning

device is fully tensioned, indicating Zhang

Short stroke clamping device should be re-adjusted.
     The correct solution is to unlock the hopper with connectors. With the hopper by the elevator into the nose, so that the end of the tensioning device on the wheel adjusted

to the highest position. Through the first round and bottom round, and both connected, so that the tension in the hopper without tension with the state. Then the tensioning

device is fully

Tensioned. At this point tensioning device untapped tension adjustment screw stroke of not less than 50% of the whole trip
      Hoist hoist overload overloaded. Cause hopper with skid. You should reduce the amount of feed materials, drag torque increases. And seeks to uniform feeding. If you reduce

the feed rate, still not improve skid, sit inside the machine may be too much or material accumulation mentor material hopper are stuck,

Should stop inspection, troubleshooting.
      Head wheel shaft and hopper band looks too smooth head round shafts and hopper band looks too smooth. Cause hopper with skid. In this case, the reduced friction between

the two. In the inner shaft and outer coat hopper with rubber to increase friction.
      Head round and bottom round head wheel bearing rotation ineffective and bottom wheel bearing rotation is not working. Cause hopper with skid. Then washable refueling or

replace bearings. Drag torque increases.
      Head round and bottom round head wheel and axle assembly errors bottom wheel axle assembly errors are mainly embodied in the following aspects: First, the end of the first

round of the wheel and drive shaft in the same vertical plane and not parallel; Second, two shafts are mounted in a horizontal position and not in the same vertical plane; three

Are two parallel shafts. Hopper with a deviation, the same vertical plane and not level. At this time. Easy to cause shock and barrel hopper, hopper bands tear. Should be

immediately shut down, troubleshooting. Be the first wheel and the bottom of the shaft means wheel in the same vertical plane, and are in the horizontal position

Set on the machine centerline height 1000mm vertical deviation of less than 2mm accumulated deviation does not exceed 8mm
      Hopper with connectors errors hopper with hopper with connector does not exactly mean combined. While tight side hopper with loose, hopper band edge line is not a straight

line. Working. The hopper with lateral movement to the tight side, deviation occurs, causing the hopper containing material is not sufficient, discharge is not complete, return

Materials increased, decreased productivity, resulting in severe hopper with card edge, torn. At this time should be shut down, fix joints and connected.
      Elevator back to the material means material in the unloading position not fully discharged outside the machine. If the elevator back to the material too much, but there

are local materials hoist machine back seat of the phenomenon. Enhance job. Bound to reduce production efficiency, increase power consumption and material breakage. Causing

material back more

The following reasons:
     Hopper to run too fast Lifting different materials. Rate of about 1 ~ 2m / s; improve bulk materials, the speed of operation is different from the hopper: Average enhance

dry powder and pellets when. Speed ​​of 0.4 ~ 0.6m / s; enhance the moist powder and pellets, the speed of

0.6 ~ 0.8m / speed is too large, early discharge, causing material back. At this time should be based on improvement of materials, appropriate to reduce the speed of the hopper

to prevent back feed.
      Entrance of the discharge head tongue plate device inappropriate. Cause back feed. Should be timely adjusted tongue position, tongue position is too far away from the

hopper discharge. Prevent back feed.
       Hopper is off in production. Will produce abnormal sound, tape falling from the hopper hopper phenomenon. Hopper is dropped. To timely stop to check, otherwise, will lead

to more hoppers deformation, shedding; connection location hopper, hopper band tear. Shedding occurs hopper

The main reasons are: a feed too much feed too much, causing the inside of the base material in the accumulation of resistance increases elevator, hopper runs sluggish, the

occurrence of the hopper off, the direct cause of deformation. You should immediately shut down, out of the base under the flapper, from the plane seat backlog and replacement

of new hopper

, Then drive production. Then reduce the feed rate, and seeks uniformity.
      Inlet position too general. Hopper scooping themselves come from the material inlet. If the feed inlet position is too low, hoist in production. Will result in no time

scooping material hopper, while most of the material into the machine base, causing the hopper scoop materials. The material is massive, it is

Easily lead to deformation of the hopper, fall off. At this time, you should adjust the position of the inlet end of round above the centerline.
       Hopper material is not good. It has a high data requirements, the intensity is limited hopper hoist bearing member. Device should try matching strength good information.

Usually, the hopper with ordinary steel or galvanized sheet metal welding or stamping, folding the edges using galvanized wire or involvement

To enhance the strength of the hopper.
       Boot inside the base does not clear a backlog of material in production. If more boot, often encounter a sudden power failure or other causes shutdown of the phenomenon.

No clear backlog inside the base material, it is easy to cause the hopper by the impact of too big to break off. So, stop and start between

, Must clear the backlog within the frame of physics, to prevent the hopper off. Also, regularly check the hopper and the hopper is firmly connected with, the screws loose, fall

off and the hopper skew, damage and other phenomena, it shall promptly repair or replace, to prevent more accidents happen.

Conveyor history

Chinese ancient drum trucks and high lift water overturned bucket promotion of modern machines and scraper conveyor prototype; 17th century, began to apply ropeway transport

bulk materials; 19th century, the delivery of a variety of modern architecture machine after another thrown.
In 1868, a lot of attention in the UK belt; 1887, in the United States thrown a screw conveyor; 1905 in Switzerland thrown a steel belt conveyor; 1906, in the United Kingdom and

Germany thrown inertia conveyor. Thereafter, conveyors manufactured by mechanical, electrical, chemical and metallurgical industry technology to improve the impact of continuous industrial belt conveyor

improvement, gradually from the inside to complete the delivery of the workshop, developed to accomplish within the enterprise, between enterprises and even between cities

material handling, become material mechanization and automation of handling systems indispensable component departments.Airport conveyor

Transportation machinery by the use of zoning can be divided into

1, bulk material handling machinery (eg: belt \ Screw \ bucket promotion machine \ inclined conveyor)

(A) by a conveyor belt tensioning device drives the central structure and composition of the roller conveyor as towing and carrying member, so as to continuously fed into pieces

scattered and fragmentary materials or goods.check weighers

Friction drive conveyor is a continuous manner for material transport machinery. Apply it, the material can be transported in a certain line, from the initial feed point to the

ultimate discharge point between the formation of a material transfer processes. It can be granular material transport can also be carried into the delivery of items. In

addition to the purely material handling, but also with various industrial enterprises in the production process of matching the requirements of the process, the formation of

the rhythmic flow homework transport line. So conveyor is widely used in various industrial enterprises in the modern.

In the underground mine workings, mine ground transportation systems, open pit and processing plant, widely applied conveyor. It is used for horizontal transport or inclined

transportation.

Universal conveyor from the conveyor belt, roller, roller and the drive, brakes, tension, bend, loading, unloading, cleaning and other equipment components.spiral conveyor

① conveyor

Commonly used with two kinds of rubber bands and plastic. Rubber band together for the working environment temperature -15 ~ 40 ° C between. Material temperature does not

exceed 50 ° C. Upward transport of Granules inclination 12 ° ~ 24 °. Available for large transmission angle tread rubber band. Plastic belt with oil, acid, alkali and other

strengths, but for the weather and poor adaptability, easy to slip and aging. Bandwidth is the main technical parameters of belt conveyor.

② roller

Of single drum (tape on the drum wrap angle of 210 ° ~ 230 °), double drum (wrap angle of 350 °) and multi-cylinder (for power) and so on. There trough roller, flat-shaped

roller, spherical roller, buffer roller. Trough roller (2 to 5 by the roller composition) supporting bearing branches for conveying granular materials; aligning roller to adjust

the lateral position with, to avoid deviation; buffer roller mounted in place by the material to reduce the impact of material on the belt.

③ drum

Minute drive rollers and bend pulley. Drive rollers are main components of power transmission. Of single drum (tape on the drum wrap angle of 210 ° ~ 230 °), double drum (wrap

angle of 350 °) and multi-cylinder (for power) and so on.

④ tensioning device

Its role is to achieve the necessary belt tension to avoid slipping on the drive roller and make conveyor belt between the deflection rollers ensures delineated range.

Belt edge technology

The first is its reliable operation. Require continuous operation in many important production units, such as the transport of coal power plants, steel mills and cement

conveying bulk materials, as well as loading and unloading of ships in ports all adopts belt conveyor. If the shutdown these occasions, the loss is great. If necessary, take a

class to a group of belt conveyor can work continuously.

Conveyor low power consumption. Because the material almost no relative movement of the conveyor belt, not only the running resistance (about 1/3-1/5 scraper conveyor), but also

the wear and broken cargo are small, production rate. These are conducive to lower production costs.

Conveyor belt conveyor line adaptable and flexible. Line length according to need. Short as a few meters, length up to 10km or more. Can be installed in a small tunnel, the

ground transportation can also be set up in the region over the chaos and danger.

According to the process requirements, the performance is very flexible conveyor belt from a point or points by the material. Also provide multiple discharge points or several

sections. When simultaneously at several points on the conveyor belt feeding (eg Coal bunker under the conveyor) or along the longitudinal direction of the belt conveyor at any

point by averaging feeding equipment to feed conveyor, the belt conveyor machine has become a major transport route.


  

 
Coal stockpile conveyor can stockpile reclaimer roadway below, when necessary, but also to the heap of different materials are mixed. Simple materials can be discharged from the

head of the conveyor, but also by moving plow unloader or unloading vehicle longitudinal direction of the belt at any point of discharge.

(2) commonly known as the auger screw conveyor, granular or powdered materials together for the horizontal conveyor, inclined conveyor, vertical transportation and other forms.

Delivery interval varies according to deformity, usually from 2 meters to 70 meters.

Conveying principle: rotating spiral blade for screw conveyor passage of the material transported. So that the material does not rotate together with the screw conveyor blades

is the material force of its own weight and the frictional resistance of the material conveyor chassis.

Features: Screw rotating shaft is welded spiral blades, blade face delivery of materials based on a solid surface different type, belt type face, leaves and other types of face.

Screw conveyor screw axis in the direction of movement of the material with the thrust bearing to the terminal with the material to spiral axial reaction force, the captain

longer, should be added to intermediate suspension bearings.

Two screw conveyor is to have two rotating blades were welded with the rotary shaft screw conveyor. To put it plainly, is to two conveyor organic combination, consisting of a

screw conveyor.

Screw rotation axis of rotation, determines the conveying direction of the material, but generally in the design of the screw conveyor are transported in accordance with the

individual blades of rotation. When the reverse transport, it will greatly reduce the service life of the conveyor.

TD-D-type bucket elevator Product Overview:
TD type by JB3926-85 "vertical bucket elevator" design and manufacturing standards, the current domestic common bucket elevators are vertical, newer. Bucket elevator for

vertical conveying powder, granular and small block and smaller abrasive bulk materials such as grain, coal, cement

, Crushed ore, lifting height up to 40m. TD-type bucket elevator hopper equipped with four kinds of Q-type (shallow bucket), H-type (arc bottom bucket), ZD type (in deep bucket)

SD type (deep bucket).chain conveyor

TD-D-type bucket elevator basic structure:
TD-type bucket elevator by the run portion (hopper with traction tape), the upper section with a drive pulley with tensioning roller lower section, the intermediate casing,

drives, check brakes and other components, For upward transport of bulk density ρ <1.5t/m3 powder, granular and small

Like non-abrasive and semi-abrasive bulk materials such as coal, sand, coke, cement, crushed ore.
TD-type bucket elevator structure: drive TD-type bucket elevator drives come in two forms, respectively, with a YZ-type reducer ZQ (or YY) type reducer. YZ-type shaft gear

mounted directly on the spindle shaft head, eliminating the transmission platform, couplings, so that the structure is compact, light weight

, And its interior has shaped roller backstop backstop reliable. The reducer, low noise, smooth operation, and with the spindle floating installation can eliminate stress.Telescopic belt conveyor



TD-D-type bucket elevator main features:
1 drive power is small, the use-feed into the induction discharge, large capacity hopper intensive layout. Increase in materials almost no feed back and dug material phenomenon,

so less power is invalid.
(2) to enhance a wide range of these types of materials hoist, less demand, not only can enhance the general powdery, granular materials, but also enhance the larger abrasive

materials. Tightness, less environmental pollution.
3 Run the reliability, advanced design principles and processing methods to ensure the reliability of machine operation, no down time more than 20,000 hours. Lifting height is

high. Hoist running smoothly, so you can upgrade to a higher level.
4 long life, take inflow feeding hoist type, without using bucket excavating, squeezed between the materials and collision phenomenon rarely occurs. The machine was designed to

ensure that the feed material, unloading few scattered, reducing mechanical wear.

Bucket elevators Precautions in use

Bucket elevators as a wide range of applications in vertical transportation equipment, has been widely used in food, feed and seed processing industry. However, in use, there

have been some problems, as the performance and reliability enhancements to make it work, it has been improved.Weight Sorter

1 in the bucket elevator shall be provided at the bottom of the head and suction pipes and vents to ensure that the bucket elevator and feed in the discharge process will not

form a vacuum and dust spills. A well-made transportation equipment, it must be reliable sealing. But a good seal in the material discharge and intake

Process for the bound material a pressure differential, resulting in difficulties in feeding and unloading. Vents inside the bucket elevator pressure and external pressure

substantially equal. Adequate suction ventilation to avoid the dust from the overflow, avoiding waste and clean environment.Turn conveyor

2 in the bucket elevator machine head equipped with anti-reversing device. In the bucket elevator suddenly interrupted when the work force, reversing the bucket elevator is very

dangerous. Bucket elevator in the promotion process, the upstream side is filled with material bucket, the other side is emptied of material

Downstream empty bucket. Power failure, the bucket elevator reversal will occur due to gravity. With the inverted bucket material is unloaded into the bottom of the bucket

elevator until after the jam filled bucket. Since inversion is an accelerated movement, and then was suddenly stuck easily ripped basket

Bucket, the belt is damaged, or even broken. Also the bottom of the bucket elevator filled with materials, but also the bucket elevator can not start. Anti-reverse ratchet

mechanism can be used.

3 Set the drive wheel slip. In the bucket elevator capstan riveted or bonded non-slip surface, anti-(anti) wear rubber cloth, can effectively improve the driving wheel and the

coefficient of friction between the belt to prevent belt slippage and improve efficiencies. If the capstan tables too smooth, too much on the need

Belt tensioning to ensure normal operation of the hoist, the belt would be too large and reduce the tension of the belt life.

4. Install speed monitoring devices. In the bucket elevator passive wheel speed sensor part of the equipment, the sensor produces a voltage or current signal, the instrument can

be set through the maximum and minimum speed. When the bucket elevator speed outside this range, after a delay, if the speed

Still beyond the scope of the police, and disconnect the air switch, effectively protecting bucket elevators work properly.

5 using good quality belt. Facts have proved that buy high quality belt, not only can improve production efficiency, but also can greatly reduce the bucket elevator accident

rate. Do not be at immediate economic and undue loss.

6 bucket elevator belt adjustment device at work after adjustment. Respond bolt protection, good rust and dust. The bottom of the bucket elevator has a number of inspection

window, so you can easily bucket elevator belt adjustment, and can better monitor the bucket elevator

The work.

7 Set the blocking plate. In the upper part of the discharge bucket elevator installed at blocking plate, which can effectively prevent the material back into the elevator back

and bottom. Plate with a rubber stopper has a certain toughness, abrasion rubber material. Blocking plate and the distance between the bucket should be about 15mm.

8 Note bucket spacing is not too large nor too small. Bucket elevators according to the actual working capacity and motor power rationally adjust the size of the bucket spacing.
