The interior of the barrier diaphragm 16 is provided with a filter groove 17. The upper and lower positions of the inner side of the filter groove 17 are respectively provided with a first barrier permeable membrane 18 and a second barrier permeable membrane 19.

[0027] Furthermore, when the motor 6 is started and drives the connecting blade 9 on the periphery of the connecting end 8 to rotate through the driving shaft 7, the cleaning brush 10 at the bottom of the connecting blade 9 is in a rotating scraping and cleaning state for the filter surface of the filter plate 5 itself.

[0028] Furthermore, when the sliding sleeve 14 outside the guide member 12 rotates under the centrifugal force of the connecting end 8, the sliding sleeve 14 outside the guide member 12 is in a reciprocating sliding pulling state through the connecting spring 21, and the pushing brush 15 at the bottom of the sliding sleeve 14 is in a forward and backward pushing state for the cleaning brush 10 to scrape the accumulated foreign matter.
