Abstract
The utility model relates to a filter element of a filter, in particular to a filter element structure of an internal-pressure type filter using the filter element; the technical scheme of the filter element structure is as follows: the filter element is a circular ring folded by filter paper; a plurality of parallel folding marks are arranged on the filter paper; distances between the folding marks on the filter paper are arranged in a spaced manner according to such sequence: wide, secondarily wide and narrow; after the folding, bulges which are arrayed in a spaced manner according to such sequence as high, secondarily high, short, secondarily high and high are formed; and the height difference of the bulges is the same. The filter element structure has the benefits of reducing the height difference of the bulges formed by the folding marks and increasing the rigidity of the bulges, thereby achieving the purposes of high filtering precision, long service life of the filter element and obviously increasing the filtering area of an article to be filtered.
Description
Technical field
The utility model relates to a kind of filter core of filter, relates in particular to a kind of filter cartridge construction that uses the inner pressed filter of filter core.
Background technology
In the patent No. is 200720170781.4 Chinese utility model patent, a kind of filter is disclosed, this filter comprises filter core, filter core is the folding annulus that surrounds of filter paper.Filter paper is provided with many folding lines that are parallel to each other, and the spacing between each folding line is wide, narrow/wide, narrow being spaced, and folding back forms high, short, high, short spaced projection; Promptly be M type shape, in the folding annulus filter core that surrounds of described filter paper, one side the outside that is positioned at filter core of described short projection.The such structure of filter core can increase the filter area that the fluid that need to filter passes, thus elimination impurity and increasing the service life better.
The difference in height of projection is bigger, and filter core hardness is undesirable; In addition, wish that also more filter efficiency is improved on the highland.
Above-mentioned utility model is the existing innovation and creation of the inventor, explores through long-term experiment, and the inventor has done further improvement to it, makes it can solve following technical problem.
The utility model content
The technical problems to be solved in the utility model provides the filter cartridge construction of the inner pressed filter of the use filter core that a kind of filter area is bigger and hardness is high.
For solveing the technical problem, the utility model adopts following technical proposals:
Use the filter cartridge construction of the inner pressed filter of filter core, described filter core is the folding annulus that surrounds of filter paper, and described filter paper is provided with many folding lines that are parallel to each other; Spacing between the folding line on the described filter paper is wide, inferior wide, narrow being spaced, the folding back forms high, inferior high, short, inferior high, high spaced projection, the height equal difference of the described projection of height equal difference of described projection, the scope of its difference in height are that 15mm is between the 30mm.
The height equal difference of described projection, the scope of its difference in height are that 15mm is between the 30mm.
The difference in height of described projection is 25mm.
In the filter core of existing background technology, the spacing between each folding line is wide, narrow/wide, narrow being spaced, and folding back forms high, short, high, short spaced projection, and protruding difference in height is bigger; In the utility model, spacing between the folding line on the described filter paper is wide, inferior wide, narrow being spaced, the folding back forms high, inferior high, short, inferior high, high spaced projection, it is many that filter area is increased, and the difference in height of the projection that folding line forms reduces, and helps being rolled into that the hardness of filter core integral body improves behind the filter core.
In sum, the beneficial effects of the utility model are: be the difference in height of having dwindled the projection of folding line formation, increase its hardness, thereby reached the filtering accuracy height, and the filter core long service life, thing filter area to be filtered increases significant purpose.
Description of drawings
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Accompanying drawing sign: high projection 1, inferior high protruding 2, short by protruding 3.
The specific embodiment
In the inner pressed filter that uses filter core, described filter core is the folding annulus that surrounds of filter paper.
As shown in Figure 1, described filter paper is provided with many folding lines that are parallel to each other; Spacing between the folding line on the described filter paper is wide, inferior wide, narrow being spaced, folding back forms high projection 1, inferior high protruding 2, short protruding 3, inferior high protruding 2, high projection 1 spaced projection, and high projection 1, inferior high protruding 2, short protruding 3, inferior high height protruding 2, high projection 1 are followed successively by 95mm, 70mm, 45mm.
The inventor make high projection 1, inferior high protruding 2, when short protruding 3 height is the structure of 150mm, 100mm, 50mm, good when not having high projection 1, inferior high protruding 2, short protruding 3, inferior high height protruding 2, high projection 1 to be followed successively by the structure of 95mm, 70mm, 45mm, hardness can improve about 30%, and filter efficiency also can improve more than 20%.
Claims (3)
1. filter cartridge construction that uses the inner pressed filter of filter core, described filter core are the folding annulus that surrounds of filter paper, and described filter paper is provided with many folding lines that are parallel to each other; It is characterized in that: the spacing between the folding line on the described filter paper is wide, inferior wide, narrow being spaced, and the folding back forms high, inferior high, short, inferior high, high spaced projection, the height equal difference of described projection.
2. the filter cartridge construction of the inner pressed filter of use filter core as described in claim 1 is characterized in that, the height equal difference of described projection, the scope of its difference in height are that 15mm is between the 30mm.
