Filter plate assembly used in filter press

Abstract

The invention discloses a filter plate assembly used in a filter press. The filter plate assembly comprises a filter plate body (1) and a square protrusion (7) arranged on the edge of the filter plate body (1). A plurality of protrusions (2) are uniformly distributed on the upper surface of the filter plate body (1). The protrusions (2) are positioned within the square protrusion (7). Water guide grooves (3) are formed among the protrusions (2). A plurality of filter holes (4) are uniformly distributed on the water guide grooves. The projections of the protrusions (2) on the filter plate body (1) are kidney-shaped. The axes of the protrusions (2) are parallel to the axes of the protrusions (2) on their left and right sides. The axes of the protrusions (2) are on a same straight line with the axes of the protrusions (2) on their upper and lower ends. The filter holes (4) are positioned between protrusions (2) with parallel axes. The filter press filter plate assembly provided by the invention has the advantages of low resistance, high flow speed, large filtering area, and high filtering efficiency.

Description

technical field [0001] The invention relates to parts of a filter press, in particular to a filter plate assembly for a filter press. Background technique [0002] As a solid-liquid separation equipment, filter press is widely used in pharmaceutical, biochemical, food and beverage, water treatment and other industries. It has the advantages of good separation effect and wide adaptability. The filter press is divided into a plate and frame filter press and a box type filter press. The plate and frame filter press consists of a set of filter press chambers arranged alternately with filter plates and plate frames. There are through holes on the corners of the plate frame and the filter plate, which form a complete channel after assembly, and can pass into the suspension, washing water and lead out the filtrate. There are handles on both sides of the plate frame and the filter plate supported on the bearing plate, and the plate frame and filter plate are pressed by the pressing...
