[0024] The present invention provides a filter press capable of automatically cleaning sludge through improvement, and its working principle is as follows; First, the staff will place the frame 1 horizontally at the place where it is needed, and then connect the external power supply to the device, and inject the material to be processed into the filter plate 6. Then the staff will start the pressing system 4 through the control panel 3, so that the pressing plate 5 will compress the material in the filter plate 6, and the setting of the thrust plate 7 can control the pushing position of the filter plate 6. Finally, the filter plate 6 is squeezed through the diaphragm exhaust valve 8. After the water is filtered, the multi-stage filter plates 6 can be separated in sequence, thereby achieving the effect of sludge discharge; Second, the fallen sludge will be discharged from the lower hopper 9, whereby the sludge will fall onto the conveyor belt 25, and the motor 26 will start working through the control panel 3, the conveyor belt 25 will transfer the sludge at the upper end to the limiting shell 2141, and the scraper 215 at the bottom of the top of the shell 211 can scrape off the sludge adhering to the conveyor belt 25, and then fall into the limiting shell 2141 along the right end slope of the scraper 215, and after all the sludge in the filter plates 6 are discharged, the user can compact the sludge again through the flipping device 213 (the volume of the limiting shell 2141 is designed according to the sludge falling from the filter plate 6, so that the sludge can be filled after the falling is completed); Third, during this process, the control panel 3 is used to start the electric push rod 2132 to push the connecting plate 2133. During the pushing process, the rack 2134 will slide along the connecting plate 2133 in the slide rail 2135, and the gear 2136 will drive the rotating shaft 2137 to rotate in the limiting frame 2138, so that the fixing block 2139 can be turned over. Fourth, when the fixing block 2139 is flipped and inserted into the limiting groove 2142, after the housing 213101 is flipped into the limiting shell 2141, the spring potential energy generated by the spring 213102 pushes the top plate 213103 downward, thereby compacting the sludge in the limiting shell 2141, which is convenient for the staff to handle better; Fifth, when the sludge needs to be taken out, the staff pulls up the recessed handle 23 to separate the movable plate 22 from the outer shell 211, so that the block sludge in the limiting shell 2141 can be taken out for processing.
