[0028] In one embodiment, please refer to Figure 2 , a plurality of first diversion holes 411 are formed in the bottom of the material tank 410.

[0029] In this embodiment, the first diversion holes 411 help to accelerate the flow of liquid during the process of pressing the filter residue into a cake after several filter pressing plates 400 are abutted.

[0030] In one embodiment, please refer to Figure 3 , the bottom of the material tank 410 is a narrow end.

[0031] In this embodiment, the narrow end of the bottom of the material tank 410 helps to prevent the filter residue from falling off easily after being pressed into a cake.

[0035] In this embodiment, the setting of the water valve 600 helps the operator to manually control the switch and enables the liquid to be discharged and collected in time.

[0036] In one embodiment, please refer to Figure 1 , a handle 450 is installed on the outer wall of the filter pressing plate 400, at least ten filter pressing plates 400 are provided, and every two adjacent filter pressing plates 400 are abutted against each other.

[0037] In this embodiment, every two adjacent filter pressing plates 400 are abutted against each other to form a sealed space, which forms a structural basis for filter pressing.

[0038] In one embodiment, please refer to Figure 1 , the pressing member 200 includes a pressing plate 210 and a guide pipe 220, and one end of the guide pipe 220 penetrates through the pressing plate 210 and abuts against the adjacent filter pressing plate 400.

[0039] In one embodiment, please refer to Figure 2 , a groove 470 is formed on one side of the filter pressing plate 400, and a sealing ring 460 is arranged in the groove 470.

[0040] In this embodiment, the setting of the sealing ring 460 helps to enhance the sealing performance after the filter press plate 400 is abutted.

[0041] In one embodiment, please refer to Figure 2 , a groove 470 is extruded on one side of the sealing ring 460.

[0042] In one embodiment, please refer to Figure 1 , the collection box 500 includes a box body 510 and a partition plate 520. Two partition plates 520 are symmetrically arranged in the box body 510.

[0043] To better understand the present invention, the following will Figures 1 to 4 describe the technical solution of the present invention in detail:

[0044] First, start the driving member 300 to drive the pressing plate 210 to push the adjacent filter press plates 400, so that every two adjacent filter press plates 400 are abutted against each other to form a sealed space; then, inject the liquid containing filter residue into the filter press plate 400 through the material guiding pipe 220. This liquid enters different filter press plates 400 and is filtered into filter cakes in the material trough 410; then, the filtrate will enter the water valve 600 through the second diversion hole 440 and then enter the liquid collection area formed by any partition plate 520 and the box body 510; then, the driving member 300 can be started to drive the pressing plate 210 away from the filter press plate 400, so that every two adjacent filter press plates 400 are no longer abutted against each other, and the filter cakes fall off into the collection box 500; when the filter press plate 400 needs to be cleaned, the filter press plate 400 can be slid through the sliding groove 110 and the circular groove 120 in sequence until it is separated from the machine table 100, and then manually cleaned and returned to its original position. The disassembly and assembly are convenient, which is beneficial to ensuring the cleanliness of the filter press plate 400 and thus ensuring the filtering effect.

[0045] The above specific embodiments of the present invention do not constitute a limitation to the protection scope of the present invention.
