Filter element of gas filter

Abstract

The invention discloses a filter element of a gas filter. The filter element comprises outer-layer filter paper, a plastic supporting net and inner-layer filter paper. The outer-layer filter paper and the inner-layer filter paper are hollow cylindrical bodies formed through longitudinal folding. The plastic supporting net is clamped between the outer-layer filter paper and the inner-layer filter paper. The upper portion and the lower portion of the filter element are fixed in a fused mode through resin adhesive tape and a non-woven fabric gasket. Compared with the prior art, the filter element has the following advantages that a double-layer filter paper structure is adopted, the plastic supporting net is additionally arranged between the outer-layer filter paper and the inner-layer filter paper, the deformation-resistant strength of the filter element is enhanced, and meanwhile the connection problem between the outer-layer filter paper and the inner-layer filter paper is solved; due to the fact that meshes of the plastic supporting net are large, filtering of gas dirt cannot be affected, the two ends of the filter element are fixed in the fused mode through the resin adhesive tape and the non-woven fabric gasket, the structure is simple, machining is convenient, the step of welding the filter element with an outer end cover is avoided, and efficient filtering, simple manufacturing, environment friendliness and reduction of manufacturing cost are achieved.

Description

technical field [0001] The invention belongs to the technical field of novel environmental protection filter accessories, and in particular relates to a fuel filter element. Background technique [0002] The fuel filter is a device for filtering the fuel entering the engine. A center tube is set inside the filter element, and the fuel with dirt is introduced into the fuel through the center tube. After being filtered by the filter paper of the filter element, clean fuel is obtained. Since the filter paper body is longitudinal The hollow cylindrical body formed by folding has certain defects in its anti-deformation strength. Now the common solution is to fix the filter paper on the cylindrical iron frame, and connect the iron frame with the iron end cover, which increases the Material costs and processing costs also increase the weight of the filter element itself, and although the material of the filter paper is gradually updated with the development of technology, it is sti...

Problems solved by technology

[0002] The fuel filter is a device for filtering the fuel entering the engine. A central tube is set inside the filter element, and the fuel with dirt is introduced from the central tube. After being filtered by the filter paper of the filter element, clean fuel is obtained. Since the filter paper body is longitudinal The hollow cylindrical body formed by folding has certain defects in its anti-deformation strength. Now the common solution is to fix the filter paper on the cylindrical iron frame and connect the iron frame with the iron end cover, which increases the The material cost and processing cost also increase the weight of the filter element itself, and although the material of the filter paper is gradually updated with the development of technology, it is still easy to bring in dirt in a single filter, and when multi-layer filter paper is set, the multi-layer filter paper The junction of the filter has also become a problem, so a filter element with a simple structure is needed to solve the existing problems
