Preparation method of node-reinforced double-net type filter screen

Abstract

The invention discloses a preparation method of a node reinforced double-net type filter screen, and belongs to the technical field of filter screen preparation. The invention discloses a preparationmethod of the node reinforced double-net type filter screen. According to the node reinforced double-net type filter screen, node sleeve ropes are arranged at the nodes of warp yarns and weft yarns; the node can be limited into a whole; when being impacted by water flow or air flow, the warp yarns and the weft yarns simultaneously move, mutual abrasion is effectively avoided; further, the frictiondamage rate at the nodes is effectively reduced, service life is prolonged, meanwhile, the node sleeve ropes are connected into a whole through embedded net pull ropes, a hidden multi-node embeddednet can be formed in the filter screen body woven by the warp yarns and the weft yarns, therefore, the filter screen forms a double-screen structure, not only the filtering effect is effectively improved, but also the strength of the filter screen can be improved, the service life is prolonged, and meanwhile, through adoption of a slightly viscous fluid, the effect of timely reminding of breakagecan be achieved while the strength of the filter screen is improved.

Description

technical field [0001] The invention relates to the technical field of filter screen preparation, in particular to a method for preparing a node-reinforced double-screen filter screen. Background technique [0002] The filter screen is divided into textile fiber filter screen and metal filter screen, etc., which have the properties of acid resistance, alkali resistance, temperature resistance and wear resistance. The main features are direct filtration, simple process, good air permeability, uniform and stable precision, no leakage, good regeneration performance, fast regeneration speed, convenient installation, high efficiency and long service life. Stainless steel filters will not corrode, pit, rust or wear. Generally, it is mainly divided into metal rubber filter, ventilation filter, metal filter, air conditioning filter and coarse filter. When cleaning impurities during use, special attention should be paid to the stainless steel wire mesh on the filter element not to b...

AI Technical Summary

Problems solved by technology

[0004] At present, many filters are woven with warp and weft threads. At the nodes where the longitude and latitude threads intersect, when filtering, due to the impact of water flow or air flow, the longitude and latitude threads at the nodes will rub against each other, causing this part to be more easily worn than other parts. Even broken, at the same time after the wear or break, under the impact, the wear or break will expand at a very fast speed, and the filter screen is generally damaged
