Bucket elevator modification to the attention of those matters it

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 down an 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 off bucket, so that 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, usually anti-reverse ratchet mechanism.
2 in the bucket elevator shall be provided at the bottom of the head and suction tubes and vents to ensure bucket elevators and feed in the discharge process will not form a negative pressure and dust spills. A well-made transportation equipment, it must be reliable sealing. But good sealing of the material during discharge and the feed pressure difference is bound, resulting in difficulties in feeding and unloading. Vents inside the bucket elevator substantially equal pressure and external pressure, adequate suction to avoid dust from the ventilation overflow, avoiding waste and clean environment.
Bucket elevator for conveying, such as powder, granular and non-small and small abrasives Information: coal, cement, stone, sand, clay, ore, etc., as is traction hoist chain, allowing the transmission high-temperature materials. The hoist has a traffic volume increase, stable and reliable operation, long life, significant advantages.
