[0029] Further, after the filter screen plate 36 is replaced, the sealing plate 32 is covered again, and then the rotating disc 42 is rotated, so that the pressing plate 44 presses the cross beam 31, and the sealing plate 32 is tightly attached to the filter box 35 to prevent liquid leakage, the sealing ring 33 can increase the sealing effect between the sealing plate 32 and the filter box 35, and the cross beam 31 uniformly disperses the pressure received by the sealing plate 32.
