When the piston 42 moves down along the inner wall of the tank 1, the waste water is pressed and converted into circulating water through the screen 77 and the reverse osmosis membrane 41, and the circulating water is used again for glass cleaning. Compared with the reverse osmosis membrane 41 which is arranged horizontally, the reverse osmosis membrane 41 in the scheme is arranged on the side wall, so that silt impurities can be prevented from directly settling on the surface of the reverse osmosis membrane 41.
The stirring unit comprises a stirring roller 51 and blades 52, the stirring roller 51 is axially vertically arranged, two ends of the stirring roller 51 are rotatably connected to the upper inner wall and the lower inner wall of the box body, the stirring roller 51 penetrates through the piston 42 and is in threaded connection with the piston 42, the stirring roller 51 is sleeved with a one-way bearing 53 through a spline 55, a limiting ring 57 is coaxially fixed below the piston 42, the limiting ring 57 is horizontally arranged, the side wall of the spline 55 is rotatably connected with the limiting ring, and the blades 52 are rotatably connected outside the one-way bearing 53. When the piston 42 moves downwards, due to threaded connection, the stirring roller 51 is driven by the piston 42 to rotate, the spline 55 on the stirring roller 51 rotates along with the rotation, the spline 55 moves downwards along with the limiting ring on the piston 42, the inner ring of the one-way bearing 53 rotates along with the spline 55, the one-way bearing is in a separation state, namely, torque cannot be transmitted to the blade 52, and the blade 52 does not rotate; when the piston 42 moves upwards, the stirring roller 51 rotates reversely under the driving of the piston 42, meanwhile, the spline 55 moves upwards along with the limiting ring 57 and rotates reversely in the limiting ring 57, and because the one-way bearing 53 is in a reverse rotation state, the inner ring and the outer ring are meshed, so that the one-way bearing 53 can transmit torque to the blade 52, and the blade 52 and the stirring roller 51 rotate reversely together.
