1、Equipment introduce
        It is a solid-liquid separation equipment with high-efficiency, energy-saving and high automation degree. This equipment adopts the pump pressure, material gravity and air pressure or water pressure to form the differential pressure on both sides of the cloth, so it can achieve the high efficiency solid-liquid separation.

Characters：
        1) The layered structure of filter plate adopts guide device to make sure the smoothly running.
        2) It can continuously automatically finish the operation in the process of filtering, extrusion, washing, drying, discharging and filter cloth regeneration.
        3) The filter pressure can reach 1.6 Mpa. Especially have good effect on various sticky tiny materials and low moisture of filter cake.
        4) Hydraulic pressure is adopted in the drive device; keep the equipment safety in operation.
        5) Adopts PLC + touch screen + automatic valves to control, with the characteristics of flexible and simple operation, reduce the production cost and working strength.
        6.Compact structure, covers small area, large pressure and high working efficiency;

2、Function Description:
        Presently, it has applied in dehydration for mine and gangue, metallurgy, and dehydration for oxide in chemical industry, and electrolysis slag, leaching slag, as well as processing for sewage, polluted mud and waste acid.

3、Technical Index:
       Working Principle:

1) Filtrating Phase: After closing filter board frame, material slurry will be pumped into filter chamber, then through filtrate soft tube and arrive at general filtrate tube after that discharged; meanwhile, it forms filtrate disc in filtrate chamber.	Filtrating Phase
2) Once Extrusion: high pressure water enter into upper chamber through high pressure water tube, then make separating film moving to filter disc for pressing, so that to extrude liquid out from filter disc.	Once Extrusion
3) Washing (optional): washing liquid is pumped into filter chamber through material slurry tube; then passing through filter disc and filter cloth and then flow into discharging pipe	Washing (optional)
4) Air Drying: through filter disc air current to carry water content, reduce filter water content to the largest extent, at the same time, discharge filtrate chamber.	Air Drying
5) Discharge Filter Disc: After finishing drying course, open board frame component, drive mechanism drive filter cloth operation, filter disc discharged from two sides of filter accompany with the cloth.	Discharge Filter Disc
