Abstract

The utility model discloses a duolateral wire -wound filter core relates to one kind and is used for petrochemical industry water treatment filter equipment, and by the skeleton, prevent that fibre shedding sheath and deep filter bands layer constitute, the cylindric structure of skeleton for having the mesh, the outer surface coating of skeleton has the fibre shedding of preventing sheath, prevents that the outside of fibre shedding sheath is equipped with deep filter bands layer, and this deep layer filter bands layer knits the line winding by the fibre to prevent that the fibre shedding sheath forms. The utility model discloses a duolateral wire -wound filter core, the filter effect is good, long service life, can be applied to field water treatments such as petrochemical widely, and its deep filter bands layer fibre is knitted the line and is utilized thickness fibre blending such as mekralon, glass fiber and cotton wool to form, has both increased wire winding tensile strength, does not lack the filter effect of wire winding itself again, especially the fibre is knitted the line surface and is done the gigging and handle the back, greatly increased the filter effect.

Description

Hornet nest type thread-winding filter element

Technical field

The utility model relates to a kind of for petrochemical industry water treatment filter, refers more particularly to a kind of hornet nest type thread-winding filter element.

Background technology

Petrochemical enterprise becomes in product process, water treatment is one of its indispensable link, in order to remove the foreign material infiltrated in water, as dust, oil droplet etc., in order to recycling or reaching qualified discharge standard, contaminant water is filtered particularly important, tradition water-oil separating filter core, often there is the shortcomings such as short or poor filtration effect in service life, how effectively to address these problems, become those skilled in the art's problem demanding prompt solution.

Summary of the invention

The purpose of this utility model is exactly to overcome the problems referred to above, provides a kind of hornet nest type thread-winding filter element.

Hornet nest type thread-winding filter element of the present utility model, be made up of come off sheath and in-depth filtration line layer of skeleton, lint, skeleton is the meshed cylinder-like structure of band, the outer surface of skeleton is enclosed with lint and comes off sheath, the come off outside of sheath of lint is provided with in-depth filtration line layer, and this in-depth filtration line layer knits line by fiber to be wound around the lint sheath that comes off and to form.

As further improvement of the utility model, the lint sheath that comes off is tea filter paper.

As further improvement of the utility model, line surface knitted by the fiber in in-depth filtration line layer protruding fine hair.

As further improvement of the utility model, the canoe that line knitted by the fiber in in-depth filtration line layer is honeycomb like from dense to sparse from inside to outside.

Hornet nest type thread-winding filter element of the present utility model, good filtration effect, long service life, field of petrochemical industry water treatment can be widely used in, its in-depth filtration line layer fiber is knitted line and is utilized the thickness fiber blends such as polypropylene fibre, glass fibre and absorbent cotton to form, both add coiling tensile strength, do not lack again the filter effect of coiling itself; Particularly fiber is knitted after line surface does napping process, considerably increases filter effect.

Accompanying drawing explanation

Fig. 1 is the structure chart of hornet nest type thread-winding filter element of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing to hornet nest type thread-winding filter element of the present utility model, be described further:

Hornet nest type thread-winding filter element of the present utility model is made up of come off sheath 2 and in-depth filtration line layer 3 of skeleton 1, lint.

As shown in Figure 1, skeleton 1 is the cylinder-like structure with mesh 4, based on skeleton 1, is provided with double-layer filter structure at the outer wall of skeleton 1, wherein, is enclosed with lint comes off sheath 2 at the outer surface of skeleton 1, and this lint comes off sheath 2 for tea filter paper.

And be also provided with in-depth filtration line layer 3 in the come off outside of sheath 2 of lint, this in-depth filtration line layer 3 knits line by fiber to be wound around the lint sheath 2 that comes off and to form, and fiber to knit line be made up of polypropylene fibre, glass fibre and absorbent cotton blending, blending increases the tensile strength that line knitted by fiber, does not lose again the character of filtration.

In order to increase filter effect, the fiber in in-depth filtration line layer 3 is knitted line surface and is done napping process, and make it have protruding fine hair, fine hair can retain dirt more, reaches more efficient filter effect.

The canoe that line knitted by fiber in in-depth filtration line layer 3 is honeycomb like from dense to sparse from inside to outside.

This device in use, the lint sheath 2 that comes off can either provide frictional force for its outer field in-depth filtration line layer 3, in-depth filtration line layer 3 is made to be firmly secured on skeleton 1, bulky grain dirt can be filtered again in the process of filtering, and in-depth filtration line layer 3 is knitted line by fiber and is entwined, and can adsorb sump oil and filter small particles dirt further.
