[0048] The working principle of this industrial wastewater plate and frame filter press dehydrator:

[0049] When in use, the staff starts the hydraulic cylinder 301 so that its output end drives the pressing plate 2 to move, so that the pressing plate 2 pushes the plate frame 6, thereby pressing the plate frame 6. Then the staff fills the wastewater into the feed pipe in the frame 1. The wastewater is filtered when passing through the plate frame 6. The sludge impurities remain in the inner cavity formed by the adjacent plate frames 6. The water flows through the drainage cavity formed by the plate frames 6 and flows out through the drainage pipe 5, thereby completing the filtration of the wastewater. Then the staff fills air into the air inlet pipe on one side of the plate frame 6, so that the diaphragm on the surface of the plate frame 6 expands, thereby squeezing the sludge, thereby performing solid-liquid separation, and the separated water is discharged through the drainage cavity. Then the staff controls the pressing plate 2 to move to its original position, and then controls the plate frame 6. Each of them moves to its original position, so that the dehydrated sludge squeezed between the plate frame 6 falls off. After the sludge falls off, the staff controls the output shaft of the first motor 14 to rotate, so that the threaded rod 8 drives the movable plate 801 to descend along the direction of the positioning groove 701 by screwing in the thread, so that the first nozzle 806 and the second nozzle 808 move to the diaphragm position of the plate frame 6, and then the staff connects the water supply equipment port with the water supply hole 804. Then the staff delivers clean water to the water supply hole 804, so that the clean water is sprayed onto the diaphragm of the plate frame 6 through the first nozzle 806 and the second nozzle 808, thereby cleaning the diaphragm to prevent these sticky water from completely falling into the recovery equipment, thereby ensuring the recovery amount of sludge and avoiding affecting the effect of sludge treatment.
