[0019] When working, after material (washing powder) is poured into sieve tray 2, fine-grained material will quickly pass through sieve tray 2 screen hole, while large-grained coagulation block will be retained on the screen, then, it (coagulation block) will be gathered to the outer edge position of sieve tray 2 by material gathering structure, and broken into small particles by broken piece 22.

[0020] Specifically, the driving assembly for driving the screen disc 2 to rotate comprises a gear ring arranged on the screen disc 2 and a driving gear wheel arranged on the output end of a rotating motor and engaged with the gear ring. During driving, the output end of the rotating motor rotates to drive the screen disc 2 to rotate through the gear transmission structure. Of course, in the present application, the driving assembly is not specifically limited, and only needs to drive the screen disc 2 to rotate, and other structures can also be adopted, for example, the screen disc 2 is directly connected with the output end of the rotating motor.
