Technical field

The present invention relates to the high pollutant holding capability of the compound large area of outer folding filter core fat greatly is wound in one kind.

Background technique

Conventional frame of filter element diameter only has 68mm, and space is small between inner frame and outer skeleton, it is difficult to it is larger to accommodate thickness Filter membrane, also be not enough to accommodate different size filter membrane combination, cause intercept and pollutant carrying capacity it is totally on the weak side, existing defects.

Summary of the invention

In view of the problems of the existing technology the present invention, provides and winds the high pollutant holding capability of the compound large area of outer folding in one kind Big fat filter core, increases skeleton accommodation space, and filter membrane has composite construction, greatly improves interception and pollutant carrying capacity.

It is as follows that the present invention solves technical solution used by above-mentioned technical problem: the compound big face of outer folding is wound in a kind of The high pollutant holding capability filter core fat greatly of product, it is characterised in that the big fat skeleton including a diameter 128-134mm, the big fat skeleton packet Inner frame and outer skeleton are included, the folding filter of the winding filter membrane and outer layer of internal layer is set gradually between the inner frame and outer skeleton Film.

The folding filter membrane includes the hydrophobic PTFE0.22 μm of center filter membrane at center, the inside of the center filter membrane and Outside setting support guide layer, the support guide layer is PET non-woven fabrics.

The internal layer filter membrane winds 10 layers, and the folding filter membrane rolls over high 14mm, 120 folding of broken number.According to filtration needs Suitable material and precision are selected, can effectively improve filter core rejection, and has and enough receives dirty space.The folding filter membrane of outer layer There are certain interdiction capability and dirty effect of receiving to large aperture particle, can effectively mitigate the filter pressure of internal layer winding filter membrane.

The outer skeleton internal diameter of the big fat skeleton is 124mm, and inner frame outer diameter is 66mm.

The internal layer filter membrane is single precision winding arrangement or more accuracy gradient winding arrangements.

The present invention uses the big fat skeleton of twice of receiving volume of conventional skeleton instead, the winding filter membrane of setting internal layer and outer in skeleton The folding filter membrane of layer promotes the integral filter ability of filter core by the composite construction of more precision, generally has filter area big, Pollutant holding capability height and the high advantage of rejection.

Specific embodiment

Below in conjunction with the attached drawing in the present invention, the technical solution in the present invention is clearly and completely described, is retouched The embodiment stated is only a part of the embodiment of the present invention, instead of all the embodiments.

The high pollutant holding capability of the compound large area of outer folding filter core fat greatly, including one are wound in one kind as Figure 1-Figure 2 The big fat skeleton of diameter 131mm, the big fat skeleton include inner frame 6 and outer skeleton 2, the inner frame and outer skeleton it Between set gradually internal layer winding filter membrane 5 and outer layer folding filter membrane 3.End cap 1 is arranged in the top of big fat skeleton, and bottom is arranged in lower part Lid 4.The folding filter membrane includes the hydrophobic PTFE0.22 μm of center filter membrane at center, the inner side and outer side of the center filter membrane Setting support guide layer, the support guide layer are PET non-woven fabrics.

Internal layer filter membrane winds 10 layers, and the folding filter membrane rolls over high 14mm, 120 folding of broken number.In the outer skeleton of big fat skeleton Diameter is 124mm, and inner frame outer diameter is 66mm.Internal layer filter membrane is single precision winding arrangement or more accuracy gradient winding arrangements.

In the present invention:

1. using φ 131mm skeleton fat greatly, there is sufficiently large operating space, it can be achieved that outside interior winding according to the present invention Foldable structure, to realize large area according to the present invention, high receive dirty property.

2. internal layer uses winding arrangement, can single precision winding, can also the winding of more accuracy gradients, selected according to filtration needs Suitable material and precision, can effectively improve filter core rejection, and greatly improve the pollutant carrying capacity of filter core.

3. outer layer uses foldable structure, the precision of filter membrane can be wound according to internal layer, the filter membrane for selecting aperture bigger was both protected Filter area has been demonstrate,proved, and the compound filter effect of more accuracy gradients may be implemented, has there is certain interdiction capability to large aperture particle With receive dirty effect, can effectively mitigate the filter pressure of internal layer winding filter membrane.

The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
