Description

Belt conveyor conveyer belt non-return and cleaning device

Technical Field

The utility model belongs to the technical field of mineral aggregate transportation, and particularly relates to a non-return and cleaning device for a belt conveyer.

Background

Belt conveyors are the primary transport equipment in the mining industry for the transfer of mineral materials such as raw ores and slimes. In the production process, when the inclined belt conveyor carries the material to be transported upwards, the machine is stopped due to power failure or motor failure, the conveyor belt can reversely run under the action of mineral aggregate gravity, mineral aggregate slides down along with the conveyor belt and flies out, so that a tail material pile is formed or mechanical equipment is damaged, and casualties are formed in severe cases. The common backstop measure at present is to additionally install a reverse self-locking device or a hydraulic brake at one end of the driving roller to stop the driving roller to realize backstop. The two methods can prevent the conveyer belt from reversing, but can cause great friction between the rubber coating of the driving roller and the adhesive tape, and can cause serious abrasion of the rubber coating of the roller after multiple operations and loss of braking effect. In addition, the conveyor belt can adhere a large amount of miscellaneous bits on the surface due to long-time material loading, and is difficult to clean. In view of the above problems, it is necessary to develop a belt stop and cleaning device for a belt conveyor.
