There is a material guide hole in the center of the filter plate, and the material flows into each filter press cavity through the material guide hole. During filtration, the material is continuously pumped by a water pump to increase the pressure in the filter press cavity, apply pressure to the material, and squeeze out the water in the material, thereby achieving solid-liquid separation. However, the ability to increase the pressure in the filter press cavity by pumping the material is limited.

The pressing plate 13 fixes the filter cloth 4 on the filter plate 5, and the material is filtered through the filter cloth 4. The liquid filtered out is filtered by the filter cloth 4 and discharged through the drainage groove (not marked). The pumping mechanism 9 continuously transports the material, increasing the The pressure in the filter press chamber 23 is increased to achieve solid-liquid separation. The filter plate 5 is connected to an adjusting ring 14 located on the outside of the pressure plate 13. An elastic member 15 is provided between the adjusting ring 14 and the filter plate 5. When the filtration reaches a certain level and the pumping mechanism 9 no longer conveys materials to increase the pressure in the filter press chamber 23, the power mechanism 7 pushes several filter plates 5 to slide through the push plate 1. The elastic member 15 contracts under pressure, reducing the volume of the filter press chamber 23, enhancing the pressure in the filter press chamber 23, further improving the filtration effect of the material, and reducing the water content of the material.
