Problems solved by technology

In order to remove impurities, a mesh or a filter medium with many micropores is often placed at the inlet, so that the liquid enters the shell after a certain filtration, but this kind of filtration is not thorough, so many impurities remain in the shell. In the liquid, and the filtration speed is low, the filter medium is difficult to clean, the cleaning is not thorough, the effective filtration area of ​​the filter medium after cleaning is greatly reduced, and it is not suitable for the filtration of high-viscosity liquids

Abstract

The invention relates to a filtering device comprising a casing, wherein a water inlet and a water outlet are formed on the top and the bottom of the casing respectively; a double-layer filter plate is arranged on the inner wall of the casing and is provided with mesh holes; filtering media are arranged between the double-layer filter plate; a filter cloth is arranged at the water inlet; a filter element is arranged on the lower part of the double-layer filter plate; the lower part of the filter element is conic; and the filter element is communicated with the water outlet. The filter media and the filtering element of the filtering device have high pollutant absorbing capability, high filtering speed, good purification effect, safety and reliability, zero pollution, and a long service life, meanwhile, residues can be sucked away by a suction pump and a suction pipe so as to prevent the filter cloth from blockage.

Description

technical field [0001] The invention relates to a filter device for separating or purifying liquids. Background technique [0002] Filtration is an important process in industrial production, such as oil filtration in petrochemical industry, filtration and purification of dyestuffs, sewage treatment in chemical production, filtration of liquor in wine making industry, etc. In order to remove impurities, a mesh or a filter medium with many micropores is often placed at the inlet, so that the liquid enters the shell after a certain filtration, but this kind of filtration is not thorough, so many impurities remain in the shell. In the liquid, and the filtration speed is low, the filter medium is difficult to clean, and the cleaning is not thorough. The effective filtration area of ​​the cleaned filter medium is greatly reduced, and it is not suitable for the filtration of high-viscosity liquids. Contents of the invention [0003] The invention overcomes the shortcomings ...
