[0002] Environmental protection projects refer to projects specifically designed for environmental protection. Due to industrial development leading to environmental pollution, environmental pollution is dealt with and resolved through the organized activities of a group of people based on a set of envisioned goals and the application of relevant scientific knowledge and technical means.

[0003] The filter press uses a special filter medium to apply a certain pressure to the object, so that the liquid is dialyzed out. It is a commonly used solid-liquid separation equipment. As a mature dehydration equipment, the filter press is widely used in the field of environmental protection. It can remove the capillary water between sludge particles and make the sludge cake-shaped, so as to save the sludge storage site and the cost incurred during the transportation process. Therefore, it has become an important equipment for sewage sludge treatment;

[0004] In the prior art, the Chinese utility model patent with patent number CN218306600U discloses a filter press device for environmental protection engineering, and has the function of realizing automatic filter press treatment of sludge water, and can quickly discharge the sludge after filter press to the outside, which is extremely convenient, and can control the action of the auxiliary filter press hydraulic cylinder to pull the filter press push plate 2 out of the filter press box, which can facilitate the cleaning operation of the inside of the filter press box, which is extremely convenient;

[0005] However, when the above device is performing filter press treatment on the sludge water, it is necessary to stop conveying the sludge water and cannot continuously treat the sludge water. Moreover, after treatment, the pressure plate needs to be disassembled and cleaned, which affects the efficiency of sewage treatment. The operation is cumbersome and inconvenient to use.

When the filter press chamber rotates to the side close to the slag discharge pipe, the protrusion will push the movable plate again to drive the pressure plate to push the sludge inside the filter press chamber out, and finally discharge it through the slag discharge pipe. After the pushing is completed, the connecting rod will be reset by the elastic force of spring 1, which is convenient for the subsequent treatment of the sludge water and realizes continuous pressure filtration treatment of the sludge water.

[0012] Furthermore, a roller is symmetrically rotatably connected to one side of the surface of the moving plate close to the protrusion, and the roller abuts against the outer wall of the protrusion.

When the push plate moves to one side of the filter screen, the rollers can store the push plate inside the rotating roller to prevent the push plate from affecting the scraping effect of the scraper on the sludge.
