A kind of blower negative pressure seals air processor

Technical field

This utility model belongs to air-treatment technical field, is specifically related to a kind of blower negative pressure and seals air processor.

Background technology

The air cleaner that can use various different filtering function at present carries out air cleaning process, different empty to solve The problem that gas is not good enough and different polluter produces, these air cleaners are typically with different types of filter element, when in the face of difference During pollution, can be in response to itself sensor measurements effective controlled wind speed of data out or distinguished and admirable path, so that it is more effective Purify air.

Higher place is required for cleaning, typically can use and carry that blower fan laminar flow hood is multiple to be merged or multiple individually make With, and enter zone of positive pressure and not yet through the air of terminal high efficiency particulate air filter, the requirement of air purity can not be reached, if Casing zone of positive pressure has leakage, it will pollute, and affects safety and the quality of product.Consider cost and processing technology, casing Splicing seams is the longest, uses the sequential welding mode that will not leak to weld, can cause the biggest deformation, and can not have leak source, and this is right Being a challenge in welder, the most general mode using spot welding to add fluid sealant processes, but owing to fluid sealant itself has certain Service life, and the leak source being generated by is difficult to lookup and benefit does not has, the most easily there is secondary chemical contamination in sealant sealing simultaneously.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of blower negative pressure to seal air processor, overcomes Deficiency of the prior art, it is to avoid the cleanliness factor of the air leakage effects air formed because box sealing is bad.

In order to solve above-mentioned technical problem, this utility model is accomplished by:

A kind of blower negative pressure seals air processor, including shell, inner shell, filter and air channel sealing surface, described outside Be provided with air inlet and air outlet on shell, inner shell, filter and air channel sealing surface be positioned at described air inlet and described air outlet it Between, inner shell is sealingly disposed in enclosure, and centrifugal blower is arranged in inner shell, and filter includes filter I, filter II and mistake Filter III, and be arranged on from bottom to top in the cavity surrounded by air channel sealing surface；

During centrifugal blower operation work, between described centrifugal blower and filter I, between filter I and filter II with And form malleation cavity I, malleation cavity II and malleation cavity III between filter II and filter III respectively, and malleation is empty The pressure size of chamber I, malleation cavity II and malleation cavity III presents successively decreases, between air channel sealing surface and shell and air inlet Forming negative pressure cavity in cavity, air is under the effect of centrifugal blower, it is ensured that air, through the process of tertiary filter, finally send Go out high-cleanness air.

Compared with prior art, this utility model has the advantages that this device utilizes air from positive pressure side to negative pressure The characteristic of end flowing, by entering the air of cavity and can leak the gas at negative pressure cavity, under the effect of centrifugal blower, Again pass by centrifugal blower and send into malleation cavity, and through the process of tertiary filter, finally send the air of high-cleanness, effectively Avoid the air penetration etc. that is that cause because box sealing is not tight and affect the situation of air cleaning.

Detailed description of the invention

With specific embodiment, detailed description of the invention of the present utility model is described in further detail below in conjunction with the accompanying drawings.

As it is shown in figure 1, a kind of blower negative pressure seals air processor, close including shell 1, inner shell 2, filter and air channel Front cover 4, described shell is provided with air inlet 11 and air outlet 12, and inner shell, filter and air channel sealing surface are positioned at described air intake Between mouth and described air outlet, inner shell is sealingly disposed in enclosure, and centrifugal blower 21 is arranged in inner shell, and filter included Filter I 31, filter II 32 and filter III 33, and be arranged on from bottom to top in the cavity surrounded by air channel sealing surface；

During centrifugal blower operation work, between described centrifugal blower and filter I, between filter I and filter II with And between filter II and filter III, form malleation cavity I 51, malleation cavity II 52 and malleation cavity III respectively 53, and the pressure size of malleation cavity I, malleation cavity II and malleation cavity III presents and successively decreases, between air channel sealing surface and shell And in air inlet cavity, forming negative pressure cavity 6, air is under the effect of centrifugal blower, it is ensured that air is through tertiary filter Process, finally send high-cleanness air.

The ultimate principle of the air processor described in this utility model is as follows:

Due to the space between filter I, filter II and filter III and the inwall of cabinet shell, and centrifugal wind Machine air inlet region is all connection, when centrifugal blower runs, creates one relative to big compression ring in this space connected Negative pressure cavity for border, and each filter is in the air-supply side of centrifugal blower, between centrifugal blower and filter I, mistake Malleation cavity I, the malleation sky successively decreased is formed respectively between filter I and filter II and between filter II and filter III Chamber II and malleation cavity III；

After pending air is by centrifugal blower effect, in centrifugal blower and filtration after being sent by centrifugal blower pressurization Between device I formed malleation cavity I, in this cavity, the leakage of any point is all leaked out to negative pressure cavity side, the air of leakage again by Centrifugal blower sucks back pressurization；The air not having leakage filters through filter I, enters and is formed between filter I and filter II Malleation cavity II, the leakage of this same cavity any point all leaks hunting wind to negative pressure cavity, and the air of leakage is again by centrifugal blower Suck back and again process；The air not having leakage filters through filter II, enters and is just formed between filter II and filter III Pressure cavity III, by that analogy, it is ensured that the air sent in filter III the most all have passed through the process of tertiary filter, makes After send out high-cleanness air.
