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.
