What are the main components and working principles of bucket elevator?

Number of visits: Release date: July 24, 2020 17:29 source: admin

Bucket elevator is mainly composed of traction parts, roller (or sprocket) tensioning device, feeding and discharging device, driving device and hopper. A series of small hoppers (called hoppers) are installed on the traction parts, which move up with the traction parts, reach the top and then turn over to discharge the materials. The hopper is usually fixed on the traction belt or chain by the back (back wall), and the double chain bucket elevator is sometimes fixed on the chain by the side wall of the hopper.

In order to change the lifting height of materials and meet the needs of different production conditions, there is a detachable section in the middle of hopper groove of inclined bucket elevator, so that the elevator can be extended or shortened. The bracket is also retractable and fixed with screws. The bracket is vertical and inclined, and the inclined bracket is fixed in the middle of the tank body. Sometimes, for the convenience of moving, the rack is mounted on movable wheels.

 Bucket elevator

The vertical bucket elevator is mainly composed of hopper, traction belt (or chain), shell of driving device and inlet and outlet. Under the drive of the driving drum, the hopper fixed on the conveyor belt scrapes up the material and rises with the conveyor belt. When it rises to the top of the driving roller, the hopper turns over. Under the action of centrifugal force or gravity, the material is discharged from the discharge port and sent to the next process.

   Bucket elevator The main components are hopper and traction parts. The hopper is the material holding component of the elevator. According to the nature of the material to be transported and the structural characteristics of the elevator, the hopper can be divided into three different forms, namely, the deep bucket with cylindrical bottom, the shallow bucket and the sharp angle bucket. There are two kinds of tractive parts of bucket elevator: belt conveyor and chain conveyor. The hopper is fixed on the traction belt with special head screw and elastic gasket. The width of the hopper is 35 ~ 40mm larger than that of the hopper.

The chain is usually sleeve chain or sleeve roller chain. When the width of the hopper is small (160 ~ 250mm), a chain is fixed to the back wall of the hopper; when the width of the hopper is large, two chains are fixed to the side plates on both sides of the hopper, that is, the side of the hopper is connected with the outer chain plate by means of angle steel. The selection of traction parts depends on the productivity, lifting height and material characteristics of the hoist. It is mainly used in factories with medium and small production capacity and medium lifting height. It is suitable for conveying powder and small particles with small volume and density. It is suitable to transport heavy materials with high production rate and high lifting height.
