After the internal threaded barrel 10 is removed from the surface of the external threaded tube 9, the residue collected inside the internal threaded barrel 10 can be discharged. The residue cleaning operation is simple and convenient, the cleaning efficiency is high, and the workload of the staff is reduced.

[0026] Furthermore, the transmission mechanism includes a housing 12, a motor 13 and a rotating rod 14. The housing 12 is fixedly connected to the side wall of the filter box 6.
