[0028] Specifically: the electric cylinder is activated by an external controller to move the first filter plate body 301 toward the side of the thrust plate 201, the sealing tube 1 303 is embedded in the sealing groove 3 207 and one end of the sealing tube 1 303 is tightly against the sealing rubber ring 3 208, the sealing tube 2 304 is embedded in the sealing groove 4 209 and one end of the sealing tube 2 304 is tightly against the sealing rubber ring 4 210, and the double-layer sealing design improves the sealing performance of the filter plate assembly 3 and the thrust plate 201; Under extrusion, the four dampers 109 relieve the pressure on the thrust plate 201, and the sealing groove 205 is tightly attached to the inner walls of the feed pipe 102 and the drain pipe 1 103, so that a sealing effect is achieved between the feed pipe 102 and the feed pipe 2 202, and between the drain pipe 103 and the drain pipe 2 203. The dampers 109 cooperate to relieve the pressure on the thrust plate 201. This design increases the pressure borne by the thrust plate and improves its practicality.

[0034] Specifically, the depths of the sealing groove three 207 and the sealing groove four 209 match the lengths of the sealing tube one 303 and the sealing tube two 304, so that under the extrusion of the pressure plate, one end of the sealing tube one 303 and the sealing tube two 304 of the first filter plate body 301 is tightly attached to the surfaces of the sealing rubber ring three 208 and the sealing rubber ring four 210, thereby achieving a sealing effect.

[0038] Specifically: the damper 109 is a common damper in the prior art, and its specific structure will not be described in detail here.

The sealing tube 2 304 is embedded in the sealing groove 4 209 and one end of the sealing tube 2 304 is close to the sealing rubber ring 4 210. The double-layer sealing design improves the sealing performance of the filter plate assembly 3 and the thrust plate 201.

The external control is electrically connected to the electric cylinder of the filter press, and the electric cylinder is started by the external controller.
