Abstract
The utility model discloses a laminar flow air filter with a shunting function. The laminar flow air filter comprises a frame and a filter paper, wherein the filter paper is encircled in the frame; the filter paper is connected with the inner side wall of the frame; the bottom of the frame is provided with annular diversion plate along the edge; the diversion plate is connected with the bottom of the frame through liner plates which are arranged at certain intervals; and a shunting gap is formed between the diversion plate and the frame. The laminar flow air filter with the shunting function has the advantages of simple and compact structure, capability of guiding leaking air out and prevention of a clean working area from being polluted.
Description
Technical field
The utility model relates to food, pharmacy package packing machine field, relates in particular to the laminar winds filter with shunting function.
Background technology
The laminar winds filter generally is made up of frame, filter paper and fluid sealant, and frame is positioned at around the filter, adopts corrosion resistant plate or section bar to be made into side U type, and frame is trapped among filter paper packet middle, and with fluid sealant filter paper and frame is sealed.Adopt the fluid sealant sealing between filter paper in the existing laminar flow wind filter and the frame; And frame adopts metal material, and the cohesive of metal material and glue is bad, easy separation; Especially adopt the high temperature high efficiency particulate air filter of ceramic glue sealing; After intensification, because the coefficient of expansion is inconsistent, ceramic glue and frame easy separation; The high temperature high efficiency particulate air filter that also has adopts fiberfill fibers that slit between filter paper and the frame is filled up; Easy like this causing separating between frame and the filter paper; When frame with after filter paper separates; Air-flow near the scuncheon wall can not get effective filtration, and this part leakage wind possibly get into clean working region, pollutes working environment.
The utility model content
The technical problem that the utility model will solve is the deficiency that overcomes prior art, provide a kind of simple and compact for structure, can derive, prevent the contaminated laminar winds filter in clean working region with leaking wind with shunting function.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of laminar winds filter with shunting function; Comprise frame and filter paper; Said filter paper is located in the frame, and said filter paper is connected with the scuncheon wall, and said frame bottom is provided with the deflector of ring-type along the edge; Said deflector is connected with the frame bottom through spaced apart backing plate, forms between said deflector and the frame and divides ebb interval.
Said deflector inboard is provided with the extension of in frame, extending.
The top of said extension is higher than the bottom of said frame.
Be provided with the sealant layer that is used to be connected between said frame and the filter paper.
Compared with prior art, the advantage of the utility model is:
The laminar winds filter with shunting function of the utility model; Be provided with the deflector of ring-type along the edge in frame bottom, this deflector can be derived the air-flow near the scuncheon wall, when frame with after filter paper separates; Leakage wind near the scuncheon wall can not get effective filtration; Deflector can be derived through dividing ebb interval will leak wind, and anti-heads wind gets into clean working region, avoids working environment to be polluted.

The specific embodiment
Fig. 1 to Fig. 4 shows a kind of laminar winds filter embodiment with shunting function of the utility model, and this filter comprises frame 1, filter paper 2 and sealant layer 3, and filter paper 2 is located in the frame 1; Filter paper 2 is connected with frame 1 madial wall through sealant layer 3; Frame 1 bottom is provided with the deflector 4 of ring-type along the edge, deflector 4 is connected with frame 1 bottom through spaced apart backing plate 5, forms the branch ebb interval 6 of strip between deflector 4 and the frame 1; Deflector 4 can be derived the air-flow near frame 1 madial wall; When frame 1 with after filter paper 2 separates, can not get effective filtration near the leakage wind of frame 1 madial wall, deflector 4 can will leak the wind derivation through dividing an ebb interval 6; Anti-heads wind gets into clean working region, avoids working environment to be polluted.
In the present embodiment, deflector 4 inboards are provided with the extension 41 of in frame 1, extending, and the top of extension 41 is higher than the bottom of frame 1, and the water conservancy diversion precision and the efficient of deflector 4 can be improved in this extension 41.
Structure below in conjunction with the utility model being applied on the efficient air outlet is done further explain to the operation principle of the utility model: efficient air outlet generally is used for medicine and electron trade; Be used for laminar winds is purified and filters, carry clean laminar winds to working environment.Efficient air outlet generally comprises air outlet casing 7, blower fan 8, fan housing 9, prefilter 10 and laminar winds filter, and blower fan 8 air outlets connect fan housing 9, and fan housing 9 is pressed in laminar winds filter top through bolt or hold down gag.
When blower fan 8 is opened; Blower fan 8 will around wind suck, wind direction shown in arrow among Fig. 2 and Fig. 3, blower fan 8 outsides and fan housing 9 outsides like this; Laminar winds filter outside and the air outlet casing 7 inner vacuum chamber 11 that form a relative sealing; After blower fan 8 suction reached the resistance 30～50Pa greater than prefilter 10, extraneous air was supplemented in the vacuum chamber 11 after filtering through prefilter 10, so there is the negative pressure of 30～50Pa in vacuum chamber 11 with respect to air outlet casing 7 outsides.In the fan housing 9 of blower fan 8 with wind to laminar winds filter top, air forms clean air and blows to clean area after filtering through the laminar winds filter.If produce with frame 1 junction with sealant layer 3 junctions or sealant layer 3 at filter paper 2 and to reveal, reveal wind shown in arrow, arrive deflector 4 after, by the negative pressure in the vacuum chamber 11 with unfiltered air in minute ebb interval 6 negative suction chambers 11.
The above-mentioned just preferred embodiment of the utility model is not that the utility model is done any pro forma restriction.Though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model.Any those of ordinary skill in the art; Under the situation that does not break away from the utility model technical scheme scope; All the technology contents of above-mentioned announcement capable of using is made many possible changes and modification to the utility model technical scheme, or is revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not break away from the utility model technical scheme, all should drop in the scope of the utility model technical scheme protection any simple modification, equivalent variations and modification that above embodiment did according to the utility model technical spirit.
