Filter plate and high-pressure piston type solid-liquid separation device made of same

Abstract

The invention discloses a filter plate and high-pressure piston type solid-liquid separation device made of the same. Vertical and horizontal staggered projecting particles are arranged on the surfaceof the filter plate facing filtered objects, and water passing through holes penetrate the filter plate and are formed among the projecting particles. The high-pressure piston type solid-liquid separation device comprises a frame, a filter component, a piston oil cylinder, a lifting oil cylinder, a guide rod, an oil pump and a control system, the lifting oil cylinder drives a filter cylinder to vertically move along the guide rod, the piston oil cylinder drives a piston to vertically move along the filter cylinder, a first filter plate body and a second filter plate body are provided with thefilter plate, and the projecting particle surfaces of the first filter plate body and a second filter plate body are oppositely arranged. By the aid of the scheme, the extruding surface of the filterplate is provided with point-like distributed projecting particles, the contact areas among the filter plate and the filtered objects are greatly increased, more moisture can be extruded by the filter plate under the same extruding force, and solid-liquid separation effects are good.

[0002] The industry discloses a piston filter, specifically referring to the patent publication number CN205073756 U, the piston filter is used to reduce the water content of sludge, and the piston filter includes a sleeve-shaped piston 1a, a sealing plate 2a, and a filter plate 3a And the discharge pipe 4a, the bottom of the sleeve-shaped piston 1a is provided with a sealing plate 2a, the bottom of the sealing plate 2a is provided with a filter plate 3a, and the upper surface and the lower surface of the filter plate 3a are horizontally provided with vertical and horizontal communication A network structure composed of linear grooves 31a, in which several through holes 32a leading to the upper and lower surfaces are provided, and the discharge pipe 4a is inserted between the sealing plate 2a and the filter plate 3a The movable end of an oil cylinder 5a is fixedly connected to the sealing plate 2a and the filter plate 3a of the sleeve-shaped piston 1a, and the sleeve-shaped piston 1a is driven by the oil cylinder 5a to extrude the sludge placed in the filter press cylinder 6a, The water in the sludge flows through the through holes of the filter plate 3a and discharges outward through the discharge pipe 4a, but with this arrangement, the upper and lower surfaces of the filter plate 3a are designed with criss-cross grooves. The area is large, forming surface contact with the sludge, which is not conducive to breaking up the sludge and squeezing out the water in the sludge. At the same time, due to the use of a single oil cylinder, the extrusion force is weak, and the sleeve-shaped piston 1a and the filter press There is no guide device between the cylinders, when the cylinder moves downward, the sealing plate 2a and the filter plate 3a are prone to deflection
