The hydraulic pressure clamping mechanism of the filter press consists of a hydraulic station, a cylinder, a piston, a piston rod and a hydraulic shaft of the Haveland card hydraulic pump connected to the pressure plate. The motor, the oil pump and the relief valve are adjusted. Directional valve, pressure gauge, oil circuit, fuel tank.
Filtration method: The way the filtrate flows out is clear flow filtration and dark flow filtration. For the clear flow filtration, a water nozzle is arranged on the lower liquid outlet of each filter plate, and the filtrate flows out intuitively from the water nozzle. Under the dark flow filtration, a liquid outlet hole is arranged below each filter plate, and the liquid outlet holes of the plurality of filter plates are connected into a liquid outlet passage, which is discharged by a pipe connected by a liquid outlet hole below the thrust plate.
Washing method: When the filter cake needs to be washed, it sometimes flows in one-way washing and two-way washing, undercurrent one-way washing and two-way washing.
