As you know that the recovery system is very important part for shot blasting machine and the recovery system is consist of screw conveyor system, elevator system, separate system and abrasive control system.
Bucket elevator is also very important part for blast recovery system, so we will introduce the bucket elevator and how is the bucket elevator doing work for the shot blasting machine.
Bucket elevator is composed of cycloidal pin gear reducer, upper and lower roller, transmission belt, bucket, closed abrasive storage hopper and tensioner. The feed port of the bucket elevator is connected with the crosswise screw conveyor, and the discharge port is connected with the screw roller sieve of the separator. In order to ensure that the belt conveyor does not skid on the surface of the drum during the bucket elevator works, the roller surface is welded with steel plates into a cage shape.
When the screw conveyor finish collect the abrasive, the next is all the abrasive will be into the bucket elevator. But how is the bucket elevator doing work in the shot blast machine?The abrasive dropped to the separator at the force of gravity In the process of working, the hopper in the transport belt brings the abrasives from the bottom, and drop at the gravity. Using polyester transport belt, squirrel cage roller, intermediate slightly protruding, which not only improves the lifting friction between the belt and pulley, avoiding the old light pulley slippage, but also reduces the lifting belt pretension force, extending the life of lifting tape. And can prevent the projectile stuck in between the lower pulley and the belt so the belt deviation phenomenon, flowing from the projectile between the spokes and the belt. Bottom shaft on the lifting having pulse wheel, can detect the tracking work status. Hoist not turn once or slippage failure, timely feedback signals to the PLC process alarms to ensure the safe operation of the equipment.
