Abstract
The utility model discloses a kind of washable reusable air filtering core, its key points of the technical solution are that：It includes upper end cover, and bottom end cover, skeleton is equipped between upper end cover and bottom end cover, combination filtering layer is fixed with the outside of skeleton, and the sealing ring of sealing combination filtering layer is equipped with the top of upper end cover.The filter efficiency of air filtering core described in the utility model is substantially better than paper air filter element, and initial resistance is significantly lower than paper air filter element, and reusable after cleaning, the service life is far longer than paper air filter element.
Description
Technical field
The utility model is related to air filtering core, particularly it is a kind of be suitable for machinery field carry out the washable of air filtration can
The air filtering core of reuse.
Background technology
Domestic automobile engine air filter core at present, engineering machinery air filtering core, air compressor machine air filtering core, gas electricity generator
The group cylindrical empty such as air filtering core, self-cleaning air filtering core filter element uses wood pulp cellulose filter paper mostly, reaches when dust blocks
It easy cleaning or can not cleaned at all during service life, consume substantial amounts of tree resources, cause the very big wasting of resources,
Under the increasing overall situation of environmental protection pressure, there is an urgent need for it is a kind of without using wood pulp cellulose filter paper, the filter core used can be cleaned repeatedly
To fill a hole in the market.
And existing patent《A kind of nanometer washes air filtering core》（Authorization Notice No. CN206299486V）With《A kind of nanometer
Fiber coat super-hydrophobic automatic cleaning filtering element for air filter and manufacture method》（Apply for notification number CN106377948A）Deng above-mentioned
Technology, which still needs using wood pulp cellulose filter paper, is used as base material, it is impossible to accomplishes the cleaning of filtering layer positive and negative clear water or the positive blowback of compressed air
Cleaning, and the processing technology of above-mentioned patent is complicated, is not easy to produce processing use in enormous quantities.
The content of the invention
The purpose of this utility model is to provide a kind of washable reusable air rational in infrastructure, using effect is good
Filter core.
The technical solution of the utility model is that a kind of washable reusable air filtering core, it includes upper end cover, under
End cap, it is characterised in that：Skeleton is equipped between upper end cover and bottom end cover, combination filtering layer is fixed with the outside of skeleton, in upper end
The top of lid is equipped with the sealing ring of sealing combination filtering layer.
The structure ecto-entad of the combination filtering layer is followed successively by：Polyester or polyethylene nonwoven protective layer, high molecular nanometer
Fibrous layer, polyester non-woven fabric substrate layer.
The polyester or polyethylene nonwoven protective layer is by one layer of 10g/m2~120g/m2Hydrophobic polyester non-woven fabrics or
Hydrophobic polyethylene non-woven fabrics；The high polymer nanometer fiber layer is to be existed by high molecular polymer by electrospinning process combining
One layer of nanofiber on mylar, a diameter of 80nm~800nm of fiber, the aperture of fiber is 0.5um~40um；Polyester without
Woven fabric substrate layer is by one layer of 80g/m2~240g/m2Nonwoven polyester（PET）Composition.
Preferably, end cap is polyurethane PU or surface treated metal material up and down as described above.
Preferably, it is as described above it is a kind of it is washable can the air filtering core reused of air cleaner, skeleton is by nylon
Or ABS injection moldings, or surface treated metal material, pass through the metal foil web material of the spiral processing method withheld
Material, can bear pressure difference, the strength of stability higher of filter core of higher.
Preferably, it is as described above it is a kind of it is washable can the air filtering core reused of air cleaner use metal end
When, upper end cover is sealed using polyurethane sealing ring.
The beneficial effects of the utility model are：
The filter efficiency of air filtering core described in the utility model is substantially better than paper air filter element, and initial resistance is substantially low
Reusable after paper air filter element, cleaning, the service life is far longer than paper air filter element.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is Figure 1A-A sectional views.
Fig. 3 is the partial enlarged view in Fig. 2 I portions.
Embodiment
Embodiment is described in detail with reference to the figures above,
A kind of washable reusable air filtering core, it includes upper end cover 2, bottom end cover 5, in upper end cover and bottom end cover
Between be equipped with skeleton 4, combination filtering layer 3 is fixed with the outside of skeleton, the top of upper end cover be equipped with sealing combination filtering layer sealing
Circle 1；The structure ecto-entad of the combination filtering layer is followed successively by：Polyester or polyethylene nonwoven protective layer 3-1, high molecular nanometer
Fibrous layer 3-2, polyester non-woven fabric substrate layer 3-3.
The utility model：
Corrugating machine can be first passed through to be molded composite filter discounting, then noted evenly around on skeleton, then by mould
Enter polyurethane PU glue upper end cover, bottom end cover, skeleton, composite filter injection molding.
Metallic framework filter core is being centered around on skeleton by corrugating machine discounting uniform in shaping, Ran Houyong by composite filter
Epoxide-resin glue is bonded upper end cover, bottom end cover, skeleton and composite filter, and instant drying adhesive adhering and sealing is finally used on upper end cover
Adhesive tape.
Combination filtering layer has the high characteristic of the low mechanical filtration efficiency of resistance, polyester non-woven fabric by high polymer nanometer fiber layer
Base material has a water-proofing performance, hydrophobic polyester or hydrophobic nonwoven protection high molecular polymer layers of nanofibers, reach it is washable can
The filter effect of air cleaner Reusability；The filter efficiency of the air filtering core is substantially better than paper air filter element, initial resistance
Power is significantly lower than paper air filter element, and reusable after cleaning, the service life is far longer than paper air filter element.
The above embodiments are merely examples for clarifying the description, and the restriction not to embodiment.For institute
For the those of ordinary skill in category field, other various forms of changes or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments, and the obvious change or change thus extended out
Within the dynamic protection domain created still in the utility model.
