In this way, when the cam sets 32 rotate, the filter screen plate 31 can cyclically vibrate to prevent its own blockage, and can quickly return to position when displaced.

[0031] It should be noted that the two sets of cam sets 32 are symmetrically distributed, and the number of cams in each cam set 32 is not less than two, and the filter box 12 is provided with a stepped groove, and the elastic supporting component is installed on the filter box 12 through the stepped groove. The elastic supporting component includes a cover 33, four sets of through holes are formed on the cover 33, and a connecting rod 34 is slidably connected in the through hole, that is, the diameter of the connecting rod 34 is equal to the diameter of the through hole, and the bottom end of the connecting rod 34 is fixedly connected with the filter screen plate 31. The top end of the connecting rod 34 is fixed with a top hat 35 having a diameter greater than that of the through hole, and a spring 36 is sleeved on the outside of the connecting rod 34 between the top hat 35 and the cover 33. In this way, the spring 36 can keep the filter screen plate 31 normally at rest, and can move the filter screen plate 31 upward when the cam sets 32 lift the filter screen plate 31.

[0032] In order to keep the precipitate in a suspended state and reduce sedimentation, as shown in Figure 2 and 3 As shown, the agitator 4 in the embodiment is rotatably connected in the collecting box 11, and works when the driving source in the driving structure 5 is started, for keeping the precipitate suspended to reduce sedimentation.

[0033] It needs to be explained that the collecting box 11 is provided with a closed cover 6 through bolt fixation, the closed cover 6 has four groups of side walls, the left side and the bottom side are hollow, which can protect the transmission components and the double-shaft motor 51, the double-shaft motor 51 is bolted to the inner side wall of the closed cover 6, for example, the right side wall, and the transmission components include two groups of transmission rods one 52, which are rotatably connected to the front and rear side walls of the closed cover 6, and a bevel gear two 54 connected with the other output end of the double-shaft motor 51 is meshed with the bevel gear one 53 at the opposite end of the two groups of transmission rods one 52, so that when the double-shaft motor 51 is started, the bevel gear two 54 can rotate and complete subsequent transmission, and the bevel gear three 55 is arranged on the outer side of the two groups of transmission rods one 52, and the transmission rod two 56 is rotatably connected with the filter box 12, and the bevel gear four 57 corresponding to the bevel gear three 55 is arranged on one end of the transmission rod two 56.

[0034] As shown in Figure 2 The agitator 4 includes a shaft column 41 and a plurality of agitating paddles 42, wherein the plurality of agitating paddles 42 are fixed to the outer side of the shaft column 41 and located in the collecting box 11, and the top end of the shaft column 41 is fixedly connected with the corresponding output end of the double-shaft motor 51.

[0035] When the double-shaft motor 51 is started, the double-shaft motor 51 drives the agitator 4 to rotate, so that the precipitate can be kept in a suspended state, reducing precipitation, and the double-shaft motor 51 drives the bevel gear two 54 to rotate when started, and since the bevel gear two 54 is meshed with the two groups of bevel gear one 53, the two groups of bevel gear one 53 will rotate and drive the transmission rod one 52 and the bevel gear three 55 to rotate, and the subsequent transmission rod two 56 will drive the cam group 32 to rotate, so that the filter screen plate 31 can be cyclically lifted to make the filter screen plate 31 cyclically vibrate up and down, avoiding the filter screen plate 31 from being blocked.
