[0020] Among them, several filter elements 11 can be embedded in the filter box 9, at least two of which are arranged at a certain distance from top to bottom. A limiting ring 12 is provided on the upper edge of the filter box 9 to prevent the filter box 9 from falling. When the limiting ring 12 is in contact with the support ring 3, the air outlet pipe 13 has extended out of the sealing ring 14.

[0021] In this embodiment, specifically, a sealing cover 2 is fixed to the top of the tank body 1 by bolts, and a sealing ring 14 is embedded at the center of the bottom of the tank body 1;

[0022] The sealing ring 14 can be used to seal the joint between the gas outlet pipe 13 and the tank body 1 to prevent leakage of internal liquid and gas.

[0023] In this embodiment, specifically, both sides of the tank body 1 are connected through a U-shaped connecting pipe 19 arranged in a mirror image, and both ends of the U-shaped connecting pipe 19 are respectively located above and below the support ring 3;

[0024] The two U-shaped connecting tubes 19 are used to circulate the gas below the filter box 9 to the top of the filter box 9. Moreover, the two ear-hanging connecting tubes 19 can also facilitate taking the tank body 1.

[0025] In this embodiment, specifically, one side of the tank body 1 is connected through a water inlet pipe 18 and an air inlet pipe 15 located below the connecting pipe 19. The air inlet pipe 15 is Z-shaped, with one upper end penetrating to the outside of the tank body 1, and the remaining pipe body is located below the filter box 9 inside the pipe body, and is provided with a plurality of aeration holes 16. The bottom of one side of the tank body 1 is also connected through a water outlet pipe 17;
