Description
Technical field
It the utility model is related to filter plant, the HEPA filters of particularly a kind of replaceable cartridge.
Background technology
In industrial production, filter is conventional equipment, particularly the filtering to air, at present, filtering industrially
Device is entirely to use galvanized steel plain sheet or aluminum alloy outer frame, reinforcing bar inner support, and housing corner uses rivet interlacement, disposably to abandon
Structure, after dust containing capacity reaches whole resistance, filter will be scrapped, it is necessary to re-replace new filter, both waste of materials, again
Time-consuming, and due to problem present on structure, filter effect is single, cost is high, changes trouble, and filter effect is also not to the utmost
People's will, it is impossible to ensure to being fully cleaned up of air, filter, therefore, the improvement and innovation on filter are imperative.
Utility model content
For the above situation, to overcome the defect of prior art, the purpose of the utility model is just to provide a kind of replaceable
The HEPA filters of filter core, can effectively solve the problem of being convenient for changing filtrate, simple to operate, saving material, ensureing filter effect.
The technical scheme that the utility model solves is, including housing, inside casing and filter core（Filtrate）, housing and inside casing are through one side
On the hinge that is equipped with snap together, the primarily efficient filter that needle punched non-woven fabrics form is housed with VELCRO seal on housing periphery
Layer, primarily efficient filter layer it is following（Back）Interior inframe, which is welded, horizontally-parallel support frame, and support frame is equipped with the filter that filtrate is formed
Core, filter core are following by primarily efficient filter layer successively（Back）Cold catalyst cellular board filter layer, HEPA-F7 filter layers, activated carbon mistake
Filtering layer, HEPA-F9 filter layers, long filament chemical fibre filter paper filter layer are formed.
The utility model is simple in construction, novel and unique, use easy to install, filter core（Filtrate）It is replaceable, the repeatable profit of housing
With the easily manufacturing, saving raw material, using effect is good, there is good economic and social benefit.
Brief description of the drawings
Fig. 1 is housing inner frame structure connection figure of the present utility model；
Fig. 2 is structural perspective of the present utility model；
Fig. 3 is filter cartridge construction figure of the present utility model（Partly cut-away）；
Fig. 4 is the utility model outer frame part front view.
Embodiment
Specific embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.
As Figure 1-3, the utility model includes housing 1, inside casing 2 and filter core 5（Filtrate）, housing 1 and inside casing 2 are through one side
On the hinge 3 that is equipped with snap together, the primarily efficient filter that needle punched non-woven fabrics form is housed with VELCRO seal on the periphery of housing 1
Layer 1-1, primarily efficient filter layer 1-1's is following（Back）Being welded in inside casing 2 has horizontally-parallel support frame 4, and support frame 4 is equipped with filtrate
The filter core 5 of composition, filter core 5 are following by primarily efficient filter layer 1-1 successively（Back）Cold catalyst cellular board filter layer 5-1, HEPA-
F7 filter layers 5-2, activated carbon filter layer 5-3, HEPA-F9 filter layers 5-4, long filament chemical fibre filter paper filter layer 5-5 are formed.
The primarily efficient filter layer 1-1 of needle punched non-woven fabrics composition is housed on the periphery of housing 1 with VELCRO seal, the structure can be just
In cleaning replacement.
In order to ensure using effect and easy to use,
Catching groove is provided with described inside casing 2, support frame 4 is mounted in catching groove,（Do not indicated in figure）, described housing 1 is by 4
Individual outer frame body, which joins end to end to be linked together by rivet 6, forms square, described inside casing 2 to be consistent with housing 1 square,
Housing 1 is fastened on inside casing 2.
There is fixed support 7 on the described periphery of filter core 5.
Described cold catalyst cellular board filter layer 5-1 thickness is 10mm.
There is the tree lace 1-2 parallel to each other being bonded on housing 1 described primarily efficient filter layer 1-1 tops.
Working condition of the present utility model is that first, air enters housing by air inlet, through the primarily efficient filter layer on housing
1 μm of dust is filtered out, filter efficiency is 25% or so.
2nd, using 10mm thickness cold catalyst cellular boards, the bacterium in the dust granule of interception is killed, no longer breed bacteria, prevented
Major structure is into secondary pollution.
3rd, the HEPAF7 filter layers made using PP, 0.4 μm of dust, filter efficiency 80% are filtered out.
4th, formaldehyde in air etc. is harmful to, had the gas interception of peculiar smell by active carbon filter；Using diameter 2-3mm fruit trees
Charcoal.
5th, HEPA filters are made using efficient low-resistance filter material（F9）, 0.4 μm of dust is filtered out, filter efficiency 95% is rear attached
One layer filament chemical fibre filter paper, protect filter material not contaminated in transport, installation, dust granule will not be adsorbed.
The utility model compared with prior art, has following advantageous effects：
1st, filtrate（Filter core）Change convenient, simple, fast.
2nd, multiple filtration effect synthesis is integrated, and good filtration effect, can effectively remove the pollution particle in air.
3rd, it is easy to install, small volume, save installing space.
4th, structure novel and unique, easily production, cost are low.
5th, housing, inside casing, support frame can be repeatedly utilized so that, reduce the wasting of resources, reduce use cost, there is good economy
And social benefit.
