Problems solved by technology
[0003] The working principle of a general filter press is to use a pressure pump to press mud into a closed filter chamber formed by two adjacent filter plates, so that a pressure difference is formed on both sides of the filter cloth, thereby achieving solid-liquid separation, but the traditional separation efficiency is low, so , an improved technology is urgently needed to solve this problem existing in the prior art

Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] see figure 1 , the present invention provides a technical solution: a method for increasing the filter press efficiency and effect of a filter press, comprising the following steps:
[0020] Step 1: Connect an air compressor with a gas pipe at the water inlet of the filter press;
[0021] Step 2: Open the oil cylinder of the filter press, press all the filter plates between the movable head plate and the fixed tail plate, so that the filter chamber is ...

The invention discloses a method for improving the filter pressing efficiency and the filter pressing effect of a filter press. The method comprises that an air compressor is connected to the water inlet of a filter press through a gas pipe; the oil cylinder of the filter press is opened; all filtering plates are pressed between a movable head plate and a fixed tail plate, so that filtering chambers are formed between the adjacent filtering plates, and the peripheries of the filter chambers are sealed; a to-be-filtered material liquid enters each filtering chamber from material inlet holes inthe end of a pressing top plate through a material conveying pump under a certain pressure; through a filtering cloth, solids are intercepted in the filtering chambers and gradually form filter cakes;the air compressor is opened, and continuously injects air into the closed filtering chambers to increase the pressures in the closed filtering chambers, so that the more water in the filtering cakesis squeezed out. According to the invention, the air compressor is connected o the top head of the filter press, and the test results show that the water content of the filter cake is reduced from 80% to 45% by additionally arranging the air compressor, so that the filter pressing efficiency of the filter press is greatly improved, and the sewage treatment efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a method for increasing the filtration efficiency and effect of a filter press. Background technique [0002] In daily industrial production, the treatment of the three wastes is a problem that must be paid attention to. The treatment of waste water is a more critical section in the treatment of three wastes. [0003] The working principle of a general filter press is to use a pressure pump to press mud into a closed filter chamber formed by two adjacent filter plates, so that a pressure difference is formed on both sides of the filter cloth, thereby achieving solid-liquid separation, but the traditional separation efficiency is low, so , a kind of improved technology is urgently needed to solve this problem existing in the prior art. Contents of the invention [0004] The purpose of the present invention is to provide a method for increasing the effic...
