pipe; and hot-air blowers are fixedly mounted on the two sides of the working box. Through the arrangement of the pump body, the
servo motor, the air cylinder and the cleaning
brush, the pump body sucks out cleaning liquid through the liquid suction
pipe and sprays the cleaning liquid to the cleaning
brush and the cover plate through the liquid outlet
pipe, then the air cylinder and the
servo motor are started through an external controller, the air cylinder pushes the movable plate to move downwards, and the movable plate drives the supporting plate, the
servo motor and the cleaning
brush to move downwards; the cleaning brush can extend into the filter screen drum, the servo motor drives the cleaning brush to rotate, the filter screen drum can be effectively cleaned, the influence on next-time
continuous use is prevented, meanwhile, manual cleaning by workers is not needed, and the trouble of the workers is reduced.
