Water mist cleaning method for return section of coal conveying belt

Abstract

The invention discloses a water mist cleaning method for a return section of a coal conveying belt, and aims to solve the problems that a belt cleaner in the prior art can only utilize a scraper to simply clean residual coal carried at the return end of the belt, as the coal contains moisture and can be adhered to the belt, the coal can be continuously scattered after colliding with a return carrier roller in the running process of the belt if the coal is not cleaned, and dust flies. The method comprises the following steps that firstly, spray flushing is conducted on the working face of the return end of the belt through a nozzle located on a spray pipe at the foremost end, and then cleaning is conducted through a front scraper; the second part sprays and flushes the working face of the return end of the belt through a nozzle on the other spray pipe, and the belt is deeply cleaned through an electric rolling brush after flushing; and thirdly, the rear scraper blade performs final water removal on the working surface of the belt, so that comprehensive cleaning of the return section of the coal conveying belt can be ensured, and the cleaning effect is ensured. The device is used for water mist rolling brush cleaning of the belt return stroke section.

Description

Technical Field

[0001] The invention relates to a water mist cleaning method for a return section of a coal conveyor belt. Background Art

[0002] When the belt conveyor is transporting coal on the return journey, a large amount of fine dust adheres to the working surface. When it passes through the return rollers and various guide rollers, or when the load changes and the tensioning force changes during the operation of the belt, the belt vibrates, causing a large amount of dust. As the dust accumulates, the belt conveyor components wear out prematurely.

[0003] The existing belt cleaner can only use a scraper to simply clean the remaining coal carried by the return end of the belt. Since the coal contains moisture, it will stick to the belt. If it is not cleaned, it will continue to fall after colliding with the return roller during the operation of the belt, causing dust to float. Summary of the invention
