Material return type bucket elevator

Abstract

The invention discloses a material return type bucket elevator, which comprises a housing, chain wheel groups, a motor, and a transmission chain, wherein the motor drives the chain wheel groups; the transmission chain is mounted on the chain wheel groups in a matching manner; a plurality of hoppers are arranged on the transmission chain; guide plates are symmetrically arranged inside the housing; and a material return groove is arranged between the guide plates in a matching manner. Through the adoption of the structure, the material return type bucket elevator provided by the invention can reduce the waste of raw material, guarantees that an elevator body is clean and tidy, and reduces the cleaning load.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a return-type bucket elevator. Background technique [0002] There are two types of traction members used in existing bucket elevators, one is a chain, and the other is an adhesive tape. Bucket elevators using chains as traction components can work in higher temperature environments (<250°C). However, due to the limitation of the structural characteristics of the chain, in order to reduce vibration and delay chain wear, the chain can only run at a very small speed (generally 0.3-1.0m / s, maximum 1.5m / s), which greatly limits the conveying capacity of this model , At the same time, due to its large structural size and self-heavy, it not only limits the improvement of the lifting height, but also is more expensive. For elevators that use belts as traction components, especially bucket elevators that use steel cord rubber belts as traction components, their conveying capacity...

Problems solved by technology

However, due to the limitation of the structural characteristics of the chain, in order to reduce vibration and delay chain wear, the chain can only run at a very small speed (generally 0.3-1.0m / s, maximum 1.5m / s), which greatly limits the conveying capacity of this model At the same time, due to its large structural size and heavy weight, it not only limits the improvement of the lifting height, but also is more expensive

For elevators that use belts as traction components, especially bucket elevators that use steel cord rubber belts as traction components, their conveying capacity and conveying height are relatively improved, but due to structural characteristics and limitations of rubber materials, this type of bucket elevator The hoist has many disadvantages, such as it can only work in a low temperature environment (generally <60°C, maximum 120°C), the belt is easy to run off, installation and debugging are difficult, the rubber belt needs to be specially made, and the manufacturing and maintenance costs are high, etc.

Therefore, for a long time, the conveying capacity and lifting height of the existing bucket elevator have not been significantly improved.
