Filter for filtering liquid

Abstract

The invention belongs to the technical field of filter apparatuses and particularly relates to a filter for filtering liquid. The filter comprises a discharging part, a locking fastener, a sealing ring, a filtering net and a feeding part, wherein the discharging part is fixedly connected with the feeding part through the locking fastener; the sealing ring and the filtering net are sequentially arranged between the discharging part and the feeding part; the filtering net is in close contact with the sealing ring, and by virtue of the locking fastener, the close sealing is achieved. The filter formed by means of assembling simple components is simple in structure, easy to wash and dismantle, low in production cost and filtrate loss, high in filtering precision, long in service life and the like; more importantly, the filter also comprises a connecting part, and multiple structures can be additionally arranged to meet the requirements of users on precision.

Description

technical field [0001] The invention belongs to the technical field of filter devices, in particular to a filter for liquid filtration. Background technique [0002] Filters are classified from medium to include air filters, liquid filters, network filters and light filters, while liquid filters include water filters, oil filters and electronic glue filters, etc. With the rapid development of electronic products , electronic glue is used when assembling electronic products, and electronic glue filters are needed to make good electronic glue, and the existing electronic glue filters usually use filter bags (or filter screens), and the filter bags are installed on In the filter chamber, during use, the liquid flows into the filter screen from the outside of the chamber and is filtered, and the filtered impurities are blocked and adsorbed on the outer surface of the filter bag, while the clean filtrate is discharged through the outlet in the filter bag. It is easy to use. [...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned filter still has the following disadvantages: 1) It adopts the filtering method of outside in and inside out. After filtering, the pollutants and impurities are adsorbed on the outer surface of the filter bag, which is easy to fall off and pollute the equipment. The cleaning or replacement will affect the production efficiency; 2) The filter bag or filter screen is usually made of fiber material, which is relatively soft and has a rough surface, which is difficult to clean and has poor filtering effect; 3) During the long-term working process of the filter , often block the filter holes of the filter bag or filter screen, and need to be replaced or cleaned after reaching a certain amount of impurity storage, and the filtration efficiency is low
