The hydraulic clamping mechanism of the filter press consists of a hydraulic station, a cylinder, a piston, a piston rod, and a Havlan card hydraulic station connecting the piston rod and the clamping plate. The structure of the hydraulic station consists of a motor, an oil pump, a relief valve (pressure adjustment) reversing valve, a pressure gauge, an oil circuit, and an oil tank.

Filtration method: The filtrate outflow method is divided into clear flow filtration and dark flow filtration. In clear flow filtration, a water nozzle is installed on the outlet hole below each filter plate, and the filtrate flows out of the water nozzle directly. In dark flow filtration, a liquid outlet channel hole is provided below each filter plate, and the outlet holes of several filter plates are connected into a liquid outlet channel, which is discharged from the pipe connected to the outlet hole below the thrust plate.

Washing method: When the filter cake needs to be washed, there are one-way washing and two-way washing in the open flow, and one-way washing and two-way washing in the dark flow.
