Advantages and disadvantages of bucket elevator
Bucket elevator is a continuous conveying equipment for conveying powder, granular and small block materials vertically or at large inclination angles. The advantages of the bucket elevator are that the structure is simple and compact, the cross-sectional dimension is small, which can significantly save the floor space; the lifting height is large; it has good sealing performance, which can avoid polluting the environment. The disadvantage is that it is sensitive to overload; the hopper and traction components are easy to wear; the types of conveying materials are limited.
Structure and working principle
The closed traction member is wound around the upper and lower sprockets, and is tensioned by the tensioning device on the base through the lower redirecting sprocket, which is driven by the upper driving device. The material enters from the lower feeding port, and the material is lifted to the upper part by the hopper. When the hopper bypasses the upper sprocket, the material is thrown out under the action of gravity and centrifugal force, and is transported to the silo or other equipment through the discharge port. middle. The hoist forms an endless closed loop with an ascending on-load branch and a descending unloaded return branch.
Classification method of bucket elevator
1. According to the direction of conveying materials, it is divided into vertical type and inclined type.
2. According to the discharge method, it is divided into centrifugal type, gravity type and mixed type.
3. According to the charging method, it is divided into digging type and inflow type.
4. According to the form of charging, it is divided into deep bucket type, shallow bucket type and pointed bucket type.
5. According to the form of traction member, it is divided into belt type (TD type) and chain type. The chain type is divided into ring chain type (TH), plate chain type (NE) and so on.
6. According to the working characteristics, it is divided into heavy, medium and light.
7. According to the moving speed of the hopper, it is divided into fast elevator and slow elevator. The former is unloaded by centrifugal type, and the latter is discharged by gravity type or warm-up type.
