Description

Wire-wound filter element

Technical Field

The utility model relates to a filter core, concretely relates to wire-wound filter core.

Background

The wire-wound filter element is a filter element which is refined by precisely winding fiber yarns with good filtering performance on a porous framework. The yarn material comprises polypropylene fiber, acrylic fiber, absorbent cotton fiber and the like. During winding, the filter cores with different precisions can be manufactured by controlling the winding tightness and the density of the yarns.

The conventional thread-wound filter element is formed by directly winding thread yarns on a framework, and although the thread-wound filter element has been used for many years, the thread-wound filter element still has some defects, which are mainly represented by: the fiber of the yarn wound on the framework can fall off and enter the downstream, and the two ends of the yarn are not smooth enough, so that the sealing performance of the whole filter element is affected, and the requirement of a customer cannot be met.

Disclosure of Invention

To the problem that above-mentioned prior art exists, the utility model aims at providing a simple structure, safe and reliable, small, with low costs and the good combined type wire winding filter core of filter effect.

In order to achieve the above purpose, the utility model adopts the technical proposal that: a wire-wound filter element comprises a framework, an inner filter layer, a filter screen layer and an outer filter layer from inside to outside in sequence, wherein end cover structures are packaged at two ends of the framework and the outer filter layer, and sealing rings are assembled on the end covers.

Preferably, the inner filter layer is provided on an outer edge surface of the frame.

Preferably, the inner filter layer is of a filter cloth or filter paper folding structure.

Preferably, the filter screen layer is sleeved on the outer edge surface of the inner filter layer.

Preferably, the outer filter layer is wound on the filter screen layer by yarns.

Preferably, the outer filter layer is of a honeycomb structure with sparse outer layer and dense inner layer.

Preferably, the skeleton is a porous skeleton.

Preferably, the end covers cover both ends of the wire-wound filter element and are fixed with the wire-wound filter element through high-temperature hot melting adhesion.

1) The utility model has the advantages that: the utility model has compact structure, small volume, light weight and high filtering effect;

2) the inner and outer filtering layers can protect the fibers of the yarn layer from falling off and entering the downstream, and can increase the filtering precision of the wire-wound filter element;

3) the outer edge surface of the inner filtering layer is sleeved with the filtering net, so that the function of fixing the inner filtering layer can be achieved;

the end covers are packaged at the two ends of the filter element in a hot melting way, so that the yarn fibers at the two ends of the wire-wound filter element can be prevented from falling off and entering the downstream; the sealing ring assembled on the end cover can ensure the integral sealing performance of the wire-wound filter element.

The present invention will be further explained with reference to the drawings and examples.
