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.
