Roller screen system with automatic cleaning function and using method thereof

Abstract

The invention discloses a roller screen system with an automatic cleaning function and a using method of the roller screen system. The roller screen system comprises a roller screen body, a self-cleaning system, a sealing cover plate, a compressed air source and a DCS control unit. The roller screen body comprises a screen shaft and a screen tray arranged on the screen shaft in a sleeving mode. The self-cleaning system comprises a main pipeline, a plurality of branch pipelines are arranged on the main pipeline in a communicating mode, a plurality of spray heads are arranged on the branch pipelines in a communicating mode, and the spray heads are arranged close to one side of the sieve tray; the free end of the main pipeline and the compressed air source can be connected and disconnected; the sealing cover plate is connected with a shell of the roller screen body; and the self-cleaning system and the compressed air source are electrically connected with the DCS control unit. According to the system, compressed air and the self-cleaning system are used for blowing and cleaning the roller screen body, meanwhile, the DCS control unit effectively achieves automatic control of the system, and the efficiency and safety of the cleaning process are improved.

Description

technical field [0001] The invention belongs to the technical field of coal conveying equipment for power production, and relates to a roller screen system with automatic cleaning function and a use method thereof. Background technique [0002] The existing roller screen is composed of driving motor, reducer, screen shaft, screen plate, coupling, bearing and bearing seat accessories. During the working process, the sieve pieces of each sieve shaft rotate in the same direction, so that the material moves forward along the sieve surface, and the material is stirred at the same time. With the belt conveyor, the large particle materials that do not meet the particle size requirements move forward and are sent to the crushing equipment for crushing. The existing equipment on the market is an ordinary variable inclination roller screen, which can effectively screen materials with small water content and large particle size, but when screening materials with high water content, la...

AI Technical Summary

Problems solved by technology

The existing equipment on the market is an ordinary variable-inclination roller screen, which can effectively screen materials with small water content and large particle size, but when screening materials with high water content, high viscosity and small particle size It is very easy to cause material blockage, most of which are caused by material sticking to the screen shaft and causing material blockage

At the same time, currently used screening systems such as roller screens do not have automatic cleaning devices for the screen shafts. They mainly rely on manual cleaning with a large workload, which is time-consuming and laborious, affects the operating efficiency of the entire conveying system, and has certain risks.
