[0027] Furthermore, a filter plate 22 is fixedly connected to the surface of the fixed shaft 26, the filter plate 22 is arranged inside the filter cylinder 23, and by arranging the fixed shaft 26, the filter plate 22 can be supported.

[0028] Furthermore, the number of the filter plates 22 is set to two, and the filter holes on the surfaces of the two filter plates 22 have the same size. By placing the waste liquid inside the filter element, the filter element passes through the two filter plates 22 in sequence to remove impurities.

[0029] Embodiment 2:

[0030] Refer to Figure 4 and, on the basis of Embodiment 1, it is further obtained that the disassembly mechanism 3 includes a fixing frame 31, the fixing frame 31 is fixedly connected to the top of the fixing shaft 26, and a fixing plate 32 is fixedly connected to the bottom of the fixing frame 31. The two fixing plates 32 are arranged on both sides of the cylinder 21. By providing the fixing frame 31, the fixing shaft 26 can be supported and fixed.

[0031] Furthermore, limiting grooves are opened on both inner sides of the fixing plate 32, a limiting rod 34 is inserted into the limiting grooves, a supporting plate 35 is fixedly connected to the bottom of the limiting rod 34, the supporting plate 35 is fixedly connected to the top of the supporting seat 1, a connecting plate 33 is fixedly connected to the surface of the supporting plate 35, and the cylinder 21 is fixedly connected to the surface of the connecting plate 33.
