When the adjacent filter press plates 140 are tightly attached, the receiving groove 160 and the side of the filter press plate 140 cooperate to form a filter cavity 170. The inner wall of the receiving groove 160 is provided with a plurality of ridges 180, and the ridges 180 extend in the up and down directions; the clamping mechanism includes an abutment plate 190, a pressure plate 200 and a hydraulic cylinder 210. The abutment plate 190 is connected to the first vertical plate 110, and the pressure plate 200 is slidably arranged on the guide rod 130. The hydraulic cylinder 210 is used to drive the pressure plate 200 to slide, and the pressure plate 200 and the abutment plate 190 clamp several filter press plates 140.

[0033] It can be understood that by setting the filter press plate 140, a filter cloth 150 is set between two adjacent filter press plates 140, and the filter cloth 150 is used to filter the liquid material with solids. By setting the filter press plate 140 with a receiving groove 160, the filter cloth 150 can be tightly attached to the receiving groove 160, and the hydraulic cylinder 210 is used to drive the pressure plate 200 to move horizontally. The pressure plate 200 and the abutment plate 190 clamp several filter press plates 140, so that the filter cloth 150 is clamped between adjacent filter press plates 140, and the receiving groove 160 and The side of the filter press plate 140 is cooperated to form a filter cavity 170. The solid forms a cake-shaped filter residue in the filter cavity 170. The filter residue makes the filter cloth 150 close to the inner wall of the receiving tank 160. Furthermore, by providing a plurality of ridges 180 on the inner wall of the receiving tank 160, a fault can be formed on the surface of the cake-shaped filter residue.
