The plurality of liquid-conducting hoses 11 are provided to facilitate the drainage of the treated liquid to the filter assembly plate 5 and implement filtering.

[0042] One end of a support shaft 12 is installed in the middle of the tube-mounted orifice plate 10 , and the tube-mounted orifice plate 10 and its connected parts can be placed inside an externally connected filter tank through the support shaft 12 .

[0043] Nylon sealing rings 210 are installed in the ports at both ends of the cylinder tube 2, and the nylon sealing rings 210 and the corresponding parts of the double-screw head push rod 3 are in sliding and sealing contact with each other, thereby enhancing the sealing performance of the ports at both ends of the cylinder tube 2 to the corresponding parts of the double-screw head push rod 3.

[0048] With the help of the push-pull action of the double-screw push rod 3 moving up and down, and combined with the transmission connection between the rack block 4 and the power reversing mechanism 7, the pipe shaft 740 in the power reversing mechanism 7 is in a rotating state, further driving the U-shaped rod 9 connected to the circular hole block 920 located on the pipe shaft 740 to rotate. Since the brush needles 910 are distributed on the surface of the U-shaped rod 9, the brush needles 910 located at the lower part of the U-shaped rod 9 rotate and brush the pipe hole plate 10, and the brush needles 910 located at the upper part of the U-shaped rod 9 rotate and brush the liquid inlet filter surface of the descending filter combination plate 5, thereby enhancing the cleaning intensity of impurities attached to the surface of the internal structure of the filter space and having high cleaning efficiency.
