Abstract

The utility model discloses an improved structure of a filter core of a filter. The filter comprises filter paper and hot-melt adhesive, wherein the hot-melt adhesive is uniformly and fixedly covered on the two side surfaces of the filter paper in a linear shape; the filter paper is in a continuous V-shaped folding structure; and the hot-melt adhesive that is located on the two side surfaces of the filter paper is in a non-continuous linear shape; and the non-continuous linear shaped hot-melt adhesive is respectively located on the outside surfaces of the bending parts of the filter paper. In the utility model, the folded filter paper can be guaranteed to always keep in a V-shaped structure, therefore, the effective area of the filter paper is large, and the actual utilization of the filter paper is high; meanwhile, the airflow organization structure of the filter is better, the exhausted wind is more uniform, the resistance of the filter is lower, and the service life of the filter is longer.

Description

The filter core structure-improved of filter

Technical field

The utility model relates to a kind of filter cartridge construction of filter, especially a kind of filter core structure-improved of filter.

Background technology

High efficiency particulate air filter is formed by the filter element for filtration of mid portion and frame assembled all around, when air passes through filter core, filter core can be dust in air, impurity is tackled, reach the purpose of filtration with this, in order to reach better filter effect, need be to the filter paper processing that gives a discount, reach the purpose that enlarges the filter paper area, after filter paper gives a discount separator PUR normally, and PUR is continuous linear injection moulding, is successional cloth glue mode, like this when filter paper is given a discount, filter paper will form the structure of U type, just in inboard, filter paper bending place, because the filter paper space diminishes, PUR can be piled up herein, so also caused V-structure opening part passage little, the version that foot passage is big.The result that such version can produce is: the first filter paper temporary area is big; Second under same filter area, and this paper folding technology resistance can be bigger, makes the filter efficiency of filter low, and service life is short.

The utility model content

In order to overcome above-mentioned defective, the utility model provides a kind of filter core structure-improved of filter, and the filter core structure-improved of this filter makes filter resistance low, and air-out is even, long service life.

The utility model is in order to solve the technical scheme that its technical problem adopts: a kind of filter core structure-improved of filter, filter comprises filter paper and PUR, described PUR is the linear filter paper both side surface that evenly fixedly is covered in, filter paper is continuous V-type foldable structure, the PUR that is positioned at the filter paper both side surface is discontinuous linear, discontinuous linear PUR lays respectively at the outer surface of filter paper bending place, the mutual adhesion of PUR of filter paper bending place outer surface is spaced apart with filter paper, because inboard, filter paper bending place does not have PUR, PUR can not piled up by inboard formation in the filter paper bending place, filter paper remains continuous V-structure, the assurance filter resistance is low, and air-out is even.

As further improvement of the utility model, described discontinuous linear PUR is length and is spaced in the filter paper surface, has a side to have PUR to exist like this on the sidewall of filter paper V-structure, and the intensity of filter paper is played booster action, prevents the filter paper distortion.

The beneficial effects of the utility model are: the utility model adopts discontinuous linear PUR to be distributed in filter paper bending place outer surface, guaranteed to remain V-structure after filter paper gives a discount, make that like this effective filter area is big, the practical efficiency height of filter paper, the air current composition structure of its filter is better simultaneously, air-out is more even, and the resistance of filter is lower, longer service life.

The specific embodiment

Embodiment: a kind of filter core structure-improved of filter, filter comprises filter paper 1 and PUR 2, described PUR 2 is linear filter paper 1 both side surface that evenly fixedly is covered in, filter paper 1 is continuous V-type foldable structure, the PUR 2 that is positioned at filter paper 1 both side surface is for discontinuous linear, discontinuous linear PUR 2 lays respectively at the outer surface of filter paper 1 bending place, the PUR 2 mutual adhesions of filter paper 1 bending place outer surface are spaced apart with filter paper 1, because inboard, filter paper 1 bending place does not have PUR 2, PUR 2 can not piled up by inboard formation in filter paper 1 bending place, filter paper 1 remains continuous V-structure, guarantees that filter resistance is low, and air-out is even.

Described discontinuous linear PUR 2 is length and is spaced in filter paper 1 surface, has a side to have PUR 2 to exist like this on the sidewall of the V-structure of filter paper 1, and the intensity of filter paper 1 is played booster action, prevents filter paper 1 distortion.
