Conveyor turn part of the design considerations
Belt conveyor design process often encountered in a line, not in the same straight line, then often have to consider the middle reproduced, thus affecting the economic
efficiency, transport efficiency and reliability, and other crucial health problem, and turn on the plane solves this problem within a certain range. Level turn canceled
buffers, cleaning, guide trough and other wear parts, without the risk of spillage or blockage, reducing dust emissions and noise, making the system more centralized power
supply and control system, help protect the environment, eliminating the intermediate transfer unloading feeding height, reducing unnecessary energy consumption.
Plane turning in two forms, namely forcibly guided cornering and turning to natural variability, as we say forcibly guided turn tubular belt conveyor and the change to set up a material handling conveyor
special unit at the turn change to achieve. Natural variability to the belt by turning the mechanical laws of natural bending operation. Horizontal curved conveyor belong to
this type, it is the ordinary conveyor belt, after turning radius is calculated, and according to this radius along the transmission line layout its idlers, conveyor belt can be
run on it without bending run biased.
Conveyor for natural change to take three measures to turn normally takes that basic measures, additional measures and emergency measures.
(A) basic measures
1 at the turning roller mounting support with a certain angle,automatic checkweigher
Install the support roller angle
(2) into the groove angle increases
It should be noted that, due to the turn into the groove angle changes, so that the corresponding rack, roller cradle or connections subject to change.
(B) additional measures
1 in the inner curve elevation angle. Conveyor belt in the corner formed by the inner side of the curve called the curve, while the other side is called the outer curve. Since
the curve elevation, the intermediate roller axis and the horizontal plane, said curve in the elevation angle, the aim is to reduce the turning radius of the turn is easy to
achieve a smooth course, the greater the smaller the turning radius can, but after meeting the transport Scroll to the outside of the material spilled material cause. Theory and
Practice shows elevation angle.
Raise the curve
(2) on a single roller group return branch of the two return roller conveyor between the upper pressure roller, in order to increase the transverse conveyor idlers to friction,
can reduce the return branch of the determined turning radius .
Return branch pressure roller
(Three) emergency measures
Common side emergency measures is to set the vertical roll, which is in turn at the outer side of the inner belt Li stick conveyor deviation limit. This is a safeguard against
uncertainty or adopt measures to avoid as much as possible. If the effect of such measures often, will shorten the life of the belt.
