CN104190178A - Filter net - Google Patents

Abstract

The invention relates to a filter net. The filter net comprises a supporting plate, wherein a filter net body is fixed on the supporting plate and is folded to form a plurality of strip-shaped net surfaces, every two adjacent strip-shaped net surfaces are oppositely arranged, and a wave crest and a wave trough are sequentially formed at a linking seam of the every two adjacent strip-shaped net surfaces. The filter screen is characterized in that the filter screen body comprises a first screen net surface and a second net surface, wherein a cavity is formed between the first screen net surface and the second net surface; fixed end surfaces are respectively arranged at two end parts of the filter net body; the first screen net surface and the second net surface are folded to form the strip-shaped net surfaces which form a fluctuation surface including the wave crests and the wave troughs. Compared with a common filter net body which is folded to be in a wave shape, the filter net disclosed by the invention has the advantages that the filter net body has the internal and external net surfaces, so that the filtering area is doubled, and the filtering quality is further improved.

Description

Screen pack

Technical field

The present invention relates to a kind of screen pack, especially a kind of ventilating, and the screen pack that air is filtered.

Background technology

Along with the increase of industrial expansion and population, air-polluting deterioration problem is also on the rise, and as current common pollution sources: PM2.5, human body is had to great harm.

Existing common air filter unit generally filters airborne impurity by screen pack, and current filter screen structure is generally plane reticular structure, or is folded into waveform to increase filter area.But the problem that existing screen pack exists is main or filter effect is not ideal enough.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of screen pack is provided, greatly improved filter area, further improve filter quality

According to technical scheme provided by the invention, described screen pack, comprises gripper shoe, the fixing dictyosome that filters in gripper shoe, screen pack folded body forms some strip wire sides, and adjacent two strip wire sides are oppositely arranged, and the handing-over seam of adjacent two strip wire sides forms crest and trough successively; It is characterized in that: described filtration dictyosome comprises the first wire side and the second wire side, between the first wire side and the second wire side, form cavity.

Further, at the both ends of described filtration dictyosome, fixedly end face is set respectively.

Further, described the first wire side and the second wire side are all folded into some strip wire sides, form the contoured surface with crest and trough.

Screen pack of the present invention, the common corrugated filtration dictyosome that is folded into of comparing, due to two-layer wire side inside and outside filtration ontological existence, is equivalent to filter area and is doubled again, thereby to improve further filter quality.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

Below in conjunction with concrete accompanying drawing, the invention will be further described.

As shown in Fig. 1～Fig. 2: as described in screen pack comprise gripper shoe 1, filter dictyosome 2, the first wire side 2-1, the second wire side 2-2, fixedly end face 3, cavity 4 etc.

As shown in Figure 1, the present invention includes gripper shoe 1, in gripper shoe 1, the fixing dictyosome 2 that filters, filters dictyosome 2 and is folded to form some strip wire sides, and adjacent two strip wire sides are oppositely arranged, and the handing-over seam of adjacent two strip wire sides forms crest and trough successively; At the both ends of described filtration dictyosome 2, fixedly end face 3 is set respectively;

As shown in Figure 2, described filtration dictyosome 2 comprises the first wire side 2-1 and the second wire side 2-2, between the first wire side 2-1 and the second wire side 2-2, forms cavity 4;

As shown in Figure 2, described the first wire side 2-1 and the second wire side 2-2 are all folded into some strip wire sides, form the contoured surface with crest and trough.

Operation principle of the present invention, is folded into waveform owing to filtering dictyosome 2 by several strip wire sides, has crest and trough, thereby can improve filter area; And filter dictyosome 2 and itself by the first wire side 2-1 and the second wire side 2-2, formed, between the first wire side 2-1 and the second wire side 2-2, form cavity, from and further improved filter area., owing to filtering body 2, there is inside and outside two-layer wire side in the common corrugated filtration dictyosome that is folded into of comparing, and be equivalent to filter area and be doubled again, thereby to improve further filter quality.
