Comprising a membrane frame and a shell, a fixing frame is rotationally connected to the membrane frame, a treatment membrane is installed on the fixing frame, a mounting frame is fixed to the top end of the membrane frame, a fixing frame is fixed to the inner wall of the top end of the mounting frame, a cleaning mechanism is arranged on one side of the fixing frame in a penetrating mode and comprises a lead screw rotationally connected between the inner walls of the two sides of the fixing frame, and a sliding block is screwed to the lead screw. Compared with the prior art, the fixing frame is rotated to drive the processing film to rotate, after the processing film rotates to the vertical position, the processing film is sprayed out through the high-pressure water gun on the installation piece to clean the surface of the processing film, and during cleaning, the installation piece and the high-pressure water gun are driven by the telescopic rod to continuously move downwards, so that the processing film is cleaned. And a second motor is used for driving a lead screw to rotate, the lead screw drives a sliding block to move, and then a mounting piece and a high-pressure water gun are driven to horizontally move till one face of the treatment film is cleaned up.
