Partition-plate-free open-close type filter chamber for sludge dewatering

Abstract

The utility model discloses a partition-plate-free open-close type filter chamber for sludge dewatering, and belongs to the technical field of sewage treatment. The filter chamber comprises two rectangular frames and four upright posts, and one upright post is arranged at each of four corners of each of the two rectangular frames to form a three-dimensional frame; a filter plate is arranged between every two adjacent stand columns on the inner side of the three-dimensional frame; a plurality of filter holes are formed in the filter plate; a filter chamber is defined by the filter plates; reinforcing rib plates for supporting the filter plate are arranged on the filter plate between every two adjacent stand columns on the outer side of the three-dimensional frame, wherein one side face of the filter chamber is of an open-close structure to form a filter chamber door; one side of the filter chamber door is rotationally connected with the stand columns connected with the filter chamber door, and the other side of the filter chamber door is matched with the adjacent stand columns to be closed. The filter chamber is opened / closed by arranging the filter chamber door, so that mud cakes obtained after filter pressing in the filter chamber are rapidly poured out, and the labor cost is reduced. The filter medium is directly mounted in the filter chamber, so that the time required for replacing the filter medium is shortened, and the working efficiency of the filter press is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to an open-close filter chamber without partitions for sludge dewatering, which is used in the process of municipal sludge dehydration, without partitions between the filter media, and the operating pressure Sludge mechanical filter press for dewatering treatment. Background technique [0002] At present, the common sludge dewatering filter presses on the market are mainly divided into three configurations. One is a belt type that uses two tensioned filter belts placed in parallel, and squeezes and dewaters through a series of rollers arranged up and down. The filter press has a small working pressure, generally within 0.6MPa, and the filter cloth is cleaned and replaced frequently; the other is a centrifugal filter press composed of a reload and a screw conveyor with a hollow shaft, which generates centrifugal force through rotation to dehydra...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned technical problems, in order to solve the problem of adding filter plates between the filter media of the frame-type sludge filter press for sludge dehydration, increasing labor consumption and the length of a single working time, the present invention provides a sludge Dehydration open and close filter chamber without clapboard, which installs the filter medium directly in the filter chamber of the filter press, which reduces the time required to replace the filter medium and improves the working efficiency of the filter press
