A filter assembly for closed circulating water system

Abstract

The invention discloses a filter assembly for a closed circulating water system, which uses an oil-water separation treatment tank to separate water with more oil and water with more slag, so that the water can be classified and treated according to actual conditions , effectively improve the water treatment capacity, and at the same time, prevent cross-contamination and effectively improve the filtration performance of the filter assembly. The present invention uses a spiral separation method to separate oil and water from slag water to improve the water treatment capacity. In addition, the present invention also The number of times of water circulation treatment can be controlled according to the situation, and the circulation of water filtration treatment can also be controlled according to the situation of the water tank, so as to ensure the efficiency of water filtration and the filtration effect at the same time.

Description

technical field [0001] The invention relates to the technical field of filter assemblies for circulating water systems, in particular to a filter assembly for closed circulating water systems. Background technique [0002] At present, in the process of automobile production, manufacturing and maintenance, water is one of the indispensable substances in various processes, such as processing and cooling auto parts during manufacturing, washing auto parts before production and packaging, etc. Therefore, for automobile manufacturing enterprises, a large amount of water needs to be consumed. Moreover, it is generally necessary to treat tap water before it can be used. As people continue to pay attention to water resources, how to circulate and filter the water used by automobile manufacturers has a positive effect on water conservation and environmental protection.

AI Technical Summary

Problems solved by technology

[0003] The current water filtration equipment generally passes water successively through the filter for removing debris, the oil-absorbing filter for removing oil, etc., the filtration efficiency of this method is low, and when there is more oil or debris, the other filters will be damaged. It will have adverse effects. For example, when the water discharged by the enterprise contains more oil, it will pollute the filter for removing debris, and when the debris discharged by the enterprise is more, it will pollute the filter for removing oil, which leads to Filtration of water discharged at different times contaminates different filters, making the entire water system susceptible to contamination
