Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a novel filter element. Background Art

[0002] The filter element separates solid particles from liquid or gas, or allows different material components to fully contact, speeding up the reaction time, and protecting the normal operation of equipment or the cleanliness of air. When the fluid enters the filter element with a certain specification of filter, its impurities are blocked, and the clean fluid flows out through the filter element. The liquid filter element makes the liquid (including oil, water, etc.) clean to the state required for production and life, that is, to make the liquid reach a certain degree of cleanliness.

[0003] Most of the existing filter elements are paper filter elements, which are folded and wound into a cylindrical shape, so that the cross-section of the end of the filter element is circular inside and spiked outside, and the spiked part is arranged around the outside of the circular part. The spiked part is formed by folding the filter paper together. The filtration area of ​​the filter element can be effectively increased by folding, thereby achieving the needs of improving the filtration effect or increasing the service life. The existing filter elements have different radius of the circle according to the different scenarios of use. The larger the radius of the circle, the larger the filtration area of ​​the filter element and the better the filtration effect, but the cost of use, maintenance and replacement will also be higher. If a filter element with a strong filtration effect is needed in a small device, it is necessary to specially design and reserve a large filter element placement position or multiple small filter element placement positions, which is more troublesome and has high design and production costs, so it needs to be improved.

[0005] To achieve the above-mentioned purpose, the utility model proposes a new type of filter element, including a filter element body and a filter element end cover, the filter element end cover is arranged at both ends of the filter element body, the filter element body includes filter paper, the outer periphery of the filter paper is folded in sequence to form a plurality of first folded portions, and the outer side of any first folded portion is folded inwardly to have at least one second folded portion.

[0006] Specifically, the first folding portion is folded inwardly to form two second folding portions, and the openings of the two second folding portions are outwardly facing and forming an M shape.

[0007] Specifically, the areas of two adjacent second folding portions are the same.

[0008] Specifically, the sum of the areas of the two second folding portions is greater than or equal to the area of ​​the first folding portion.

[0009] Specifically, the filter paper end cover comprises a cover body, and a first positioning groove corresponding to the first folding portion and a second positioning groove corresponding to the second folding portion are provided on the cover body.

[0010] Specifically, the distances between two adjacent first folding portions are the same.

[0011] Specifically, the distance between the folding area of ​​the first folding portion and the center of the circle is greater than the distance between the folding area of ​​the second folding portion and the center of the circle.

[0012] Specifically, the first folding portion and the second folding portion are integrally formed.

[0013] Specifically, the fold widths of two adjacent first folding portions are consistent, and the fold edges are perpendicular to the edges of the filter paper body.

[0014] The technical solution of the utility model is that the first folded part is folded and enclosed to form a filter element body, and the second folded part is arranged at the first folded part to increase the second folded part while the number of the first folded parts remains unchanged, so that the filtration area of ​​the filter element body is increased while the inner diameter of the filter element body remains unchanged, thereby improving the filtration effect.
