A vacuum filter with vertical discs consisted of fanning plates.

Filter plate immersed in the pulp while in operation produces a surface absorption of filter cake, with the action of capillarity and integrated with vacuum pressure. Filtrate enters distributing valve and drainage tank through filter plate. Filter cake comes out from slime hopper receiving spray washing. Filter cake falls into the tank by the pressure from the wind and scraper.It can be used for floating and dewatering in clean coal and fine materials like tailings, and it can be also used in metallurgy,chemical, petroleum, sewage treatment, and other aspects of the solid-liquid separation

Filter disc moves slowly in the pulp tank, with the formation of vacuum pump pressure difference, made the solid particles adsorbed on the disc filter cloth, and form the filter cake with a certain thickness. 

The filtrate through filter cake and filter cloth discharge from the central axis of the filter cake  with the pressure of air blower blade, the filter cake fell into the discharge cake tank.

1.Large filtering area, large capacity.
2.Full dehydration.
3.Markedtechnical and economic effect.
4.Small area taken, easy to manufacture and strong adsorption ability.
