Circulating water filter

Abstract

The invention discloses a circulating water filter. The circulating water filter comprises a first quick coupling, a water pump, a filter and a second quick coupling, which are connected in sequence through a pipeline, wherein the filter comprises a relatively closed shell, a cylinder which is pivoted in the shell and a plurality of spiral strips which are spirally coiled on the cylinder; a filter inlet and a filter outlet are formed in the side wall of the shell; the filter inlet and the filter outlet are coaxial; the filter inlet is communicated with the water pump; the filter outlet is communicated with the second quick coupling; a drain outlet which is connected with a drain pipe is formed in the bottom wall of the shell; a first electromagnetic valve is arranged on the drain pipe; a conductometer which is used for detecting the conductivity of the water in the shell is arranged on the side wall of the shell on one side of the drain outlet; the conductometer is in communication connection with the first electromagnetic valve. The circulating water filter is easy to maintain and strong in filter capability.

Description

technical field [0001] The invention relates to a filter, in particular to a circulating water filter. Background technique [0002] Industrial circulating water is mainly used in the cooling water system, so it is also called circulating cooling water, the purpose is to save water. Industrial circulating water is basically open and open-air. After long-term use, it is easy to produce a large amount of solid particle impurities such as dust, rust, and algae agglomeration. After these solid impurities are generated, if sewage treatment is not performed, the circulation will be blocked. pipeline, leading to the inoperability of the entire circulatory system. [0003] At present, most of the bypass water quality filtration equipment used for circulating water to remove solid particles in water use traditional filter screens and filter elements, or adopt activated carbon adsorption.

Industrial circulating water is basically open and open. After long-term use, it is easy to produce a large amount of solid particle impurities such as dust, rust, and algae agglomeration. After these solid impurities are generated, if sewage treatment is not performed, the circulation will be blocked. Pipeline, leading to the inability of the entire circulatory system to operate

[0003] At present, most of the bypass water quality filtration equipment used for circulating water to remove solid particles in water use traditional filter screens and filter elements, or adopt activated carbon adsorption. After a period of filtration, the filter screens and filter elements will be used. If the filter is blocked or the activated carbon is saturated, then the filter equipment must be disassembled, and filter elements such as the filter screen, filter element, and activated carbon must be cleaned or replaced before the entire set of filter equipment can restore the filtering function. If the water pollution is serious, the replacement will be more frequent, and Requires certain professional skills

[0004] In addition to this kind of filter screen and filter element filtration, there are also some treatment methods such as chemical decomposition precipitation method and reverse osmosis filtration method. These water treatment equipment are relatively complex in structure, bulky and costly. skills, more demanding
