Vertical Plate Pressure Filter VPA Mechanical DeWatering by Pressure
Brand: Valmet“Dewatering by through blow means replacing the water in a cake with air”.
For vertical plate pressure filters either Mechanical dewatering by pressure compression or a combination of compression and air through blow is used.
The VPA pressure filter basically consists of a fabricated head stand and an end frame, joined by two side beams, which support the movable head (pressure piece) and the filter plates, which are fitted between the fixed and movable heads.
Pulling type hydraulic cylinders, 2 for VPA 10 size and 4 for VPA 15 and VPA 20 size filters, are used to open and close the filter and to provide the necessary closing force during filtration.
Filter cloths are suspended from tubular supports and hang between the filter plates.
The cloth support bars are carried on an upper frame to which vibrator motors are fitted.
