Filter press for achieving solid-liquid separation of wastewater

Abstract

The invention discloses a filter press for solid-liquid separation of waste water. The invention comprises a frame, four guide rollers are arranged on the frame, and a plurality of filter mechanisms are set on the guide rollers. The filter mechanism It includes a filter frame and a filter plate body, the filter frame and the filter plate body are sleeved on the guide roller, the surroundings of the filter plate body protrude outward to form a frame, and the four corners of the frame are provided with positioning holes. The upper end and the lower end of the frame are respectively provided with an upper chute and a lower chute, the upper chute and the lower chute are provided with a plate body, the upper chute is provided with a first elastic pressure block, and the lower chute is provided with a There is a second elastic pressing block, the length of the first elastic pressing block is greater than the length of the second elastic pressing block, the ends of the upper chute and the lower chute are equipped with locking blocks; the center of the plate body is provided with A feeding hole, a plurality of filter holes are evenly arranged around the feeding hole, and the filter holes are equipped with a filter cloth; the frame is also provided with a filter press mechanism.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to a filter press for solid-liquid separation of wastewater. Background technique [0002] At present, filter presses are widely used in chemical, pharmaceutical, metallurgy, ceramics, silicate and other industries, as well as municipal and industrial sludge dehydration; the specific process is: using the filter pressure difference on both sides of the filter cloth to force most of the material The water flows out of the body through the filter cloth, but the material is rented to form a cake in the filter chamber, so as to achieve the purpose of filtration. For example, the invention patent with the application number of 201520862233.2 discloses a filter press, including a bracket, a filter plate correspondingly arranged on the bracket, a hydraulic cylinder, a push plate arranged on the leftmost side of the filter plate, and a filter plate arranged on the filter plate....

AI Technical Summary

Problems solved by technology

[0005] Existing filter presses use a driving mechanism to compress the filter mechanism from one direction. Since the filter mechanism is composed of multiple filter plates and filter frames, the pressure on the filter mechanism at different positions is uneven, resulting in various positions. The moisture content of the filter cake after pressing by the special filter mechanism is inconsistent
