s4: along with the movement of the threaded column (24), the threaded column (24) controls the second rack (26) to descend through the gear tube (25), at the moment, the second rack (26) pushes the movable tube (9) to extend out of the control box (2), meanwhile, the movable tube (9) extends out of the control box (2), the movable tube (9) pulls the extension plate (8) to move through the connecting plate (12), and at the moment, the extension plate (8) pulls the collecting box (6) to extend into the movable box (5);

S5: meanwhile, the limiting plate (10) moves through the elasticity of the first spring (11), and at the moment, the limiting plate (10) moves to be in contact with the bottom of the control box (2), so that the collecting box (6) is fixed;

s6: finally, the sliding door (18) can be pulled to be opened by the rotating plate (30), meanwhile, the sliding plate (23) moves, the sliding plate (23) pulls the scraping plate (28) to descend through the matching plate (27), at the moment, the scraping plate (28) scrapes impurities on the surface of the filter screen (15), the impurities enter the matching pipe (16), and are guided into the collecting box (6) through the matching pipe (16), so that the impurities are conveniently collected, and the sewage is automatically treated.
