Self-cleaning coarse grille belt conveying device, cleaning system and cleaning method

Abstract

The invention relates to a self-cleaning coarse grille belt conveying device, a cleaning system and a cleaning method. The device comprises a coarse grille cleaner, a screw conveyor, a belt conveyor,a brush roller and a driving component for driving the brush roller to move, wherein the belt conveyor and the driving component are respectively arranged at the two sides of the end, positioned outside a grille pool, of the coarse grille cleaner; a conveying belt is arranged under the end, positioned outside the grille pool, of a coarse grille rake tooth chain of the coarse grille cleaner; the belt conveyor drives the conveying belt to make circular motion; the brush roller is arranged at the side, which is positioned outside the grille pool and is close to the driving component, of the coarse grille cleaner; furthermore, the driving component can drive the brush roller to move to a place where the brush roller is contacted with the conveying belt side by side, and the brush roller is cleaned. The self-cleaning coarse grille belt conveying device controls the brush roller to be at a proper position by means of action torque current of a rotating motor and a working preset torque current range, thus achieving a better cleaning effect; therefore, the labor intensity of workers is greatly lightened, the labor cost is greatly lowered, the cleaning efficiency is increased, and the service life of the coarse grille machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of electrical control, in particular to a self-cleaning coarse grid belt conveying device, a cleaning system and a cleaning method. Background technique [0002] Since the reform and opening up, the national economy has developed rapidly, people's living standards have improved significantly, and the demand for sewage treatment has continued to grow. The construction of the sewage plant is to deal with daily domestic water and industrial water, reduce the pollution of the effluent indicators to the acceptable level of water sources such as rivers, protect natural resources and improve ecological resources, effectively protect my country's water resources, and maximize the Save water and protect water resources. [0003] In the treatment process of the sewage plant, the coarse screen sewage treatment system is an indispensable link in the sewage treatment process. Its main function is to intercept solid waste...

Problems solved by technology

[0005] During the process of the solid waste on the coarse grid conveyor belt falling into the slag collecting trolley by gravity, since the solid waste has just been fished out from the sewage and contains a lot of water, a lot of solid waste adheres to the conveyor belt through water, and gravity alone cannot If it falls into the slag collection trolley smoothly, it will stick to the belt instead, until the pulley turns to the belt surface and falls down, and finally part of the solid waste falls on the ground outside the slag collection trolley, producing many harmful organisms and greatly polluting the environment , the maintenance personnel often need to manually clean the solid waste into the trolley under the belt, the working environment is harsh, which greatly increases the labor intensity of the workers
