Filtering element and precise filter fabricated by filtering element

Abstract

The invention disclose a filtering element which comprises a core tube A, a core tube B and filter cloth, wherein the two ends of the filter cloth are wound on the core tube A and the core tube B respectively. The invention further discloses a super precise filter fabricated by the filtering element, which comprises a tank body and a plurality of filtering element groups formed by the filtering elements. The core tubes are provided with driving ends and water outlet ends, a core tube transmission mechanism is arranged on one side of the tank body, water outlet device connected with the water outlet ends of the core tubes is arranged on the other side of the tank body, and backwash water and compressed air pass through the core tubes A and the core tubes B of each filtering element group to wash the filter cloth in the cleaning process. Meanwhile, as the filter cloth is wound and unwound by the core tubes A and the core tubes B respectively for several times, dirt adsorbed on the filter cloth can be completely washed down, so that the filtering element can never be blocked. In addition, the winding tension of the filter cloth can be controlled in the rotating process of the core tubes, the compaction rate of a filtering layer is controlled, the filtering accuracy of the filtering element is adjusted, and therefore, the filter is applicable to filtering with various precision requirements.

Description

technical field [0001] The invention relates to a water treatment technology, in particular to a filter element and a super precise filter made of the filter element. Background technique [0002] At present, the filter elements of precision filters used in water treatment are made of polyethylene, polyamide and other filtering wires (hereinafter referred to as filter wires) wound on a tubular skeleton made of stainless steel or plastic materials. The filter thread on the filter element is wound on the framework at one time, that is, after the filter thread on the filter element is wound on the framework, the filter thread cannot be released and disassembled from the framework during use. When the filter element is filtered, the water to be filtered enters from the surface of the filter element, after being filtered by the filter layer formed by the filter line, enters the core tube formed by the inner skeleton of the filter element, and finally the water filtered by all th...

AI Technical Summary

Problems solved by technology

[0003] The biggest disadvantage of the current precision filter is that the filter element is prone to clogging, resulting in a decrease in the water filtration capacity of the filter element, which cannot meet the actual needs

Such frequent replacement of filter elements not only affects production, but also greatly increases maintenance costs

In order to clean the filter layer of the filter element as much as possible, some methods quickly inject a large amount of compressed air in a certain way to increase the water / air flushing intensity, but even this still cannot solve the problem of filter element clogging
