Pressure filter

Abstract

The invention relates to a pressure filter. The pressure filter comprises a support, a cylindrical closed vessel which is transversely arranged on the support, a supply pump, a pressure filter plate assembly, a pressure plate and a hydraulic cylinder, wherein a sealing cover body is arranged at the right end of the closed vessel, a water outlet is formed in the part, adjacent to the right end, of the lower part of the closed vessel, a feeding opening is formed in the upper left part of the closed vessel, and is connected with the supply pump, the pressure plate is arranged at the left end inside the closed vessel, a push rod of the hydraulic cylinder penetrates into the closed vessel and is fixedly connected with the pressure plate, the pressure filter plate assembly comprises a plurality of circular pressure filter plates, the space between every two adjacent pressure filter plates is filled with a piece of pressure filter cloth, each pressure filter plate is provided with a plurality of feeding through holes, a compression spring is arranged between two adjacent pressure filter plates, and the minimum length of each compressed compression spring is smaller than the minimum distance between the two adjacent pressure filter plates.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a filter press. Background technique [0002] The filter press is usually used for solid-liquid separation. In the existing filter press, filter cloth is filled between the filter plates. When in use, the hydraulic cylinder presses the filter plates to reduce the distance between the filter plates. Press the filter cloth to squeeze out the water in it, so as to realize the solid-liquid separation. However, in the process of adding materials to the existing filter press, the distance between the filter plates cannot be fixed. When the material is added to the closed container through the feed pump, the filter plates will shift due to the pressure of the material. It will lead to the inhomogeneous material entering between them, the material between the filter press plates near the feed port is concentrated, and the material between the filter press plates far away from t...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of local material concentration in the existing filter press pointed out in the background technology, part of the filter plate and filter cloth are frequently used and easy to be damaged, and because of the concentration of material, the problem of low solid-liquid separation efficiency is provided. A filter press capable of solving the aforementioned problems
