Abstract

The invention discloses an improved structure of a filter core of a filter. The filter comprises filter paper and a hot melt glue, wherein the hot melt glue linearly, uniformly and fixedly covers two side surfaces of the filter paper, the filter paper is of a continuous V-shaped folding structure, the hot melt glue on the two side surfaces of the filter paper are discontinuously linear, and the discontinuously linear hot melt glue is respectively arranged on the outer side surface of a bent part of the filter paper. According to the improved structure of the filter core of the filter, disclosed by the invention, the bent filter paper is always of a V-shaped structure so that the effective area of the filter paper is large, and the practical utilization rate of the filter paper is high; simultaneously, an air flow organization structure of the filter is better, air is exhausted more uniformly, the resistance of the filter is lower, and the service life is longer.

Description

The filter core structure-improved of filter

Technical field

The present invention 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, and when air passed through filter core, filter core can be tackled dust in air, impurity get off; 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; Be successional cloth glue mode, when filter paper was given a discount, filter paper will form the structure of U type like this; Just inboard in the 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.

Summary of the invention

In order to overcome above-mentioned defective, the present invention 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 present invention 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, and said PUR is linear and evenly fixedly is covered in the filter paper both side surface, and 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, and 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, guarantees that filter resistance is low, and air-out is even.

As further improvement of the present invention, said discontinuous linear PUR is length and is spaced in 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 that filter paper is out of shape.

The invention has the beneficial effects as follows: the present invention 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, made effective filter area big like this, the practical efficiency of filter paper is high; 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 comprise filter paper 1 and PUR 2, and said 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, and the PUR 2 that is positioned at filter paper 1 both side surface is for discontinuous linear, and 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, and filter paper 1 remains continuous V-structure; The assurance filter resistance is low, and air-out is even.

Said 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.
