Description
Technical Field
The invention relates to the field of filter presses, in particular to a high-efficiency filter plate and a working method thereof.
Background
The filter press is generally adopted to dewater treated slurry in the field of sludge treatment, the filter press mainly comprises a filter plate group formed by filter plate units which are arranged in a multi-layer laminating mode and are vertically placed, concave surface areas on one sides of adjacent filter plate units are mutually enclosed to form a sludge cavity used for containing the slurry, feeding holes which are communicated with each other are formed in each filter plate unit, the feeding holes on the outermost sides are communicated with a feeding pump, filter cloth is arranged on water passing plates of two adjacent filter plate units, and a space between the two filter cloth forms the sludge cavity. During filter pressing, a hydraulic oil cylinder is used for applying pressure to a filter plate group to enable the peripheral surfaces of the pressing frames on the adjacent sides of the filter plate units to be attached to seal a mud cavity, then slurry is poured into the mud cavity through a feeding pump, the mud cavity is filled with the slurry one by one through a feeding hole at one end, then the hydraulic oil cylinder continues to apply pressure, the distance between the two pressing frames in the same filter plate unit is reduced, the distance between the water passing plate surfaces of the mud cavity is gradually reduced, so that moisture in the slurry passes through the filter cloth to enter a flow channel of the water passing plate and then flows out from a water flowing groove formed in the pressing frame, and a dry mud cake is left between the two filter cloth. After the water overflows, the hydraulic oil cylinder gradually releases the pressure, each filter plate unit is gradually separated, and the whole filter pressing process is finished.
