The sealing plate 901 and the sealing ring 902 are arranged in the installation port 8. A threaded rod 903 is arranged on one side of the processing box 1. The threaded rod 903 can facilitate the rotation and movement of the positioning block 904. A positioning block 904 is arranged on one side of the sealing plate 901. The positioning block 904 can limit the sealing plate 901. A threaded hole 905 is opened on the positioning block 904. A limit block 906 is arranged at one end of the threaded rod 903.

[0025] In this embodiment, the collection tank 11 is adapted to the filter screen plate 6, and the filter screen plate 6 is placed on the bottom of the inner wall of the collection tank 11 and fixed by screws 13;

[0026] Specifically, the screws 13 can facilitate the installation of the filter screen plate 6;

[0027] In this embodiment, mounting plates 10 are fixedly installed at the bottom of both sides of the collecting member 5, the overall size of the collecting member 5 is adapted to the size of the inner wall of the processing box 1, the two groups of slide grooves 7 are respectively adapted to the two groups of mounting plates 10, the collecting member 5 is clamped in the processing box 1 and the two groups of mounting plates 10 are respectively slidably installed in the two groups of slide grooves 7;

[0028] Specifically, the chute 7 combined with the mounting plate 10 can facilitate the installation of the collecting member 5;

[0029] In this embodiment, the mounting opening 8 corresponds to and matches one end of the collecting member 5 and the two sets of mounting plates 10, and the mounting opening 8 matches the sealing plate 901;

[0030] Specifically, the mounting opening 8 can facilitate the removal of the collecting member 5;
