The working principle of pressure filter

                                              The working principle of pressure filter

Press filter composed of hydraulic pressure of the hydraulic station, oil cylinder, piston, piston rod and the piston rod and the pressure plate connection, the structure of the hydraulic station, the card has a motor, pump, relief valve (stress) directional control valve, pressure gauge, oil, fuel tank.



Filtering methods: filtrate out the way clear stream filter and undercurrent. Ming flow filter, each filter plate containing water nozzle holes below the liquid, the filtrate directly out of the water flow in the nozzle. Undercurrent filtering, the lower part of each filter plate is equipped with a fluid passage hole, several pieces of filter plate channels of produced liquid, by the thrust plate at the bottom of the hole of produced liquid discharge pipe connected.



Washing method: filter cake need washing, one-way and two-way washing washing, sometimes flow undercurrent one-way washing and two-way washing
