Abstract

The utility model discloses a multi-layer filtering filter element with a supporting dirt-containing layer, which comprises at least a first filtering layer, a second filtering layer and a third filtering layer which are arranged in parallel and are vertical to the flowing direction; the aperture of the filtering holes of the first filtering layer, the second filtering layer and the third filtering layer is gradually reduced along with the flowing water direction; a plurality of supports are arranged between the adjacent first filter layer and the second filter layer and between the adjacent second filter layer and the third filter layer, so that a gap of 0.1mm to 3mm is kept between the first filter layer and the second filter layer and between the second filter layer and the third filter layer to form a dirt holding layer. The utility model discloses an use and promote water and filter core and hold filth volume and total water capacity, slow down the filter core and be filtered off the impurity jam speed of crossing, improve the life of filter core.

Description

Multi-layer filtering filter element with supporting dirt-holding layer

Technical Field

The utility model relates to a water filtration technology field, in particular to area support holds multiple-layer filter core on dirty layer.

Background

In the prior art, the water filter element is usually a single-layer structure, so-called multi-layer composite material, namely, a plurality of different materials are laminated into a whole, and no gap exists between adjacent layers.

In practical applications, the existing water filter element can be blocked in a short time due to the filtered impurities accumulated on the surface, and finally the water filter element can be out of work.

Therefore, how to slow down the blockage of the water filter element by the filtered impurities becomes a technical problem which needs to be solved urgently by the technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

In view of prior art's above-mentioned defect, the utility model provides a take the support to hold the multiple-layer filtration filter core on dirty layer, the purpose of realization promotes water and filters the filter core and holds dirty volume and total water volume of crossing, slows down the filter core and is filtered the impurity jam rate of crossing, improves the life of filter core.

In order to achieve the above object, the utility model discloses a multilayer filter core of dirty layer is held in area support, including parallel arrangement each other, and with flowing water direction vertically first filter layer, second filter layer and third filter layer.

Wherein the aperture of the filter holes of the first filter layer, the second filter layer and the third filter layer is gradually reduced along with the flowing water direction;

adjacent first filter layer with between the second filter layer, and adjacent the second filter layer with all be equipped with a plurality of supports between the third filter layer, make first filter layer with between the second filter layer, and the second filter layer with all keep 0.1mm to 3 mm's clearance between the third filter layer and form and hold dirty layer.

Preferably, the first filter layer, the second filter layer, the third filter layer and the plurality of supports are all made of high polymer materials.

The utility model has the advantages that:

the utility model discloses an use and promote water and filter core and hold filth volume and total water capacity, slow down the filter core and be filtered off the impurity jam speed of crossing, improve the life of filter core.

The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.

Drawings

Fig. 1 shows a schematic structural diagram of an embodiment of the present invention.

Detailed Description

Examples

As shown in fig. 1, the multi-layer filter element with a supporting dirt-holding layer comprises a first filter layer 1, a second filter layer 2 and a third filter layer 3 which are arranged in parallel and are perpendicular to the flowing water direction.

Wherein, the aperture of the filtering holes 5 of the first filtering layer 1, the second filtering layer 2 and the third filtering layer 3 is gradually reduced along with the flowing water direction;

a plurality of supports 4 are arranged between the adjacent first filter layer 1 and the second filter layer 2 and between the adjacent second filter layer 2 and the third filter layer 3, so that gaps of 0.1mm to 3mm are kept between the first filter layer 1 and the second filter layer 2 and between the second filter layer 2 and the third filter layer 3 to form dirt containing layers.

The principle of the utility model lies in that, set up a plurality of supports 4 and form and hold dirty layer between the filter layer that 5 apertures of filtration diminishes gradually in a plurality of filtration pores, make and cross a plurality of filter layers that 5 apertures of filtration pore gradually diminish and can follow the aquatic respectively and filter out impurity 6 of equidimension to in the dirty layer of holding of difference respectively, promote the filter core and hold dirty volume and total water capacity.

In some embodiments, the first filter layer 1, the second filter layer 2, the third filter layer 3, and the plurality of supports 4 are made of a polymer material.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
