Description
Technical field
The utility model is related to a kind of filter core and combinations thereof structure, more particularly to a kind of new multistage composite air mistake
Filter structure.
Background technology
By taking oxygenerator as an example, air filter is used, filtering is mostly by-pass filtration, and filtering material is mostly filter pulp or PP
Inflation material, minority have secondary filtration, are mostly filter paper.Because being used for human body, after inlet end needs air filtering dust-removing to handle, just may be used
To enter system pressurized circulation, so air filtration is essential link, existing by-pass filtration is in intake process high speed
Air-flow can also generate similar " whistle " noise, and filter core is changed in the filtering of existing secondary air on the basis of the above, and increase level-one
Filter cartridge equipped with filter paper, cost are multiplied, and cut no decrease of noise functions, and operation installing and dismounting also becomes more complicated.
Summarize shortcoming：1. filter element filtering ability is limited, cross that air filtering is incomplete, and filtered air is second-rate；It is 2. empty
Gas filter efficiency is low；3. the problem of being leaked in structure there may be air without filter element filtering；4. without reduction or weaker
Reduce by 5. high expensive of noise ability；6. there are the secondary filtration of stream oriented device, installing and dismounting is all relative complex；7. filter element life
It is short.

Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the filter core structure schematic diagram of the utility model.
Specific embodiment
As Figure 1-Figure 2, a kind of new multistage composite air filtering structure, including filter chamber 1 and filter gland
2, the filter chamber 1 is equipped with air admission hole 3 and gas vent 4, and the filter chamber 1 is equipped with mounting groove 5, the mistake
Filter gland 2 is fixed with the cooperation of mounting groove 5, and filtration core 6 is equipped between the filter chamber 1 and filter gland 2, described
Filtration core 6 is combined by least two filter layers, and the filter chamber 1 forms closed air flow with filter gland 2
A variety of fixed forms can be used in cavity runner, filter gland 2 and the cooperation fixation of mounting groove 5, such as screw or other fasteners
Fixed, mounting groove 5 is connected to logical with cavity runner, is also considered as one, two filter layers use different filtering materials
Achieve the effect that multistage filtering.
The filtration core 6 includes the first filter layer 7, the second filter layer 8 and the 3rd filter layer 9, the described first filtering
Layer 7 is made of activated carbon filter cotton, i.e., filtration core 6 is three-stage filtration, and activated carbon filter cotton uses the aluminium honeycomb of through-hole structure, modeling
Expect that honeycomb, paper honeycomb are carrier, compared with conventional carbon filter screen, there is more excellent aerodynamics performance, volume is close
Spend small, large specific surface area, adsorption efficiency are high, and air resistance coefficient is small, can handle containing the benzene such as toluene, dimethylbenzene, benzene class, phenols, ester
The organic gas such as class, alcohols, aldehydes and foul gas and low concentration, all kinds of gases of Wind Volume containing micro heavy.
Second filter layer 8 is made of non-woven fabrics filter cotton, compared with other same level filter materials have stable quality,
Hold the advantages that dirt is larger, moisture-proof is strong, service life is long, economy and durability, non-woven fabrics filter cotton is by 100% pure fiber with pin thorn side
Method formed high loft, have three-dimensional depth filter layer, fibr tissue is loose, and high voidage adds the dirt of receiving of impurity
Amount, belongs to compound retention pattern, can effectively remove solid and soft particle, and larger granule foreign is trapped within fiber surface,
And fine particle is then trapped in filter material deep layer, therefore with higher filter efficiency.
3rd filter layer 9 is made of felt or non-woven fabrics filter cotton block, and the 3rd filter layer 9 is equipped with limit
Position slot 10, the filter chamber 1 is interior to be equipped with exhaust column 11, the exhaust column 11 and 10 bayonet joint of limiting slot, felt
Bond properties is good, is not easy loose, can be punched and be made variously-shaped, and tissue tight, hole is small, can be used as good filtering material,
It was the liquid such as drainage, oil with good moisture retention, and the 3rd filter layer 9 is connected with gas vent 4, while substantially from entirety
/V of the structure to it, to prevent that its is loose, swelling, therefore the 3rd filter layer 9 is bulk, can maintain fixed shape, limiting slot 10
Setting with exhaust column 11 is compared with setting narrow space that filtration core 6 is inserted into compared with gas vent 4 is connected, it is advantageous that side
Just the dismounting of filtration core 6 simultaneously as the presence of 3 grade of air admission hole, makes to generate many narrow spaces in structure, causes dismounting clear
Constant, impurity residual is washed, influences 6 service life of using effect and filtration core, can so make the rule that an entirety is formed in filter chamber 1
Then void space, though can so make a small amount of filtered air again with just mix or makes from 3 leaked-in air of air admission hole partly without
Filtered air is directly entered the 3rd filter layer 9, but can at least pass through by-pass filtration, and the 3rd filter layer 9 for block, density compared with
Height may filter that quite a few impurity, still with security, while the noise for reducing local air flow excessive velocities and generating, i.e.,
Noise reduction.
Convention is sequentially arranged for the first filter layer 7, the second filter layer 8 and the 3rd filter layer 9, but is not limited to this herein
Class order, the first filter layer 7 and the second filter layer 8 can be exchanged mutually, while the material of filter layer is not limited to the material being previously mentioned,
Other materials for having filtering function such as filter paper, filer felt, PU filter cottons also can use to replace.
It is bonded between the filter layer by glue, layers of material passes through 0.1 ~ 0.2mm thickness glue bonds, blocked up glue
Water can ventilate and be obstructed, and glue reduces composite cost.
The filtration core 6 is coated with PE films with the perpendicular both sides of air-flow direction, i.e. PE films do not hinder air to exist
Circulation in runner, at the same runner is made not intersect, not mixed flow and keep certain air-tightness, PE films be a kind of polymerization second of maturation
Alkene material, therefore it is not illustrated excessively.
The filter gland 2 is equipped with caulking groove 12, the filtration core 6 insertion caulking groove 12, and filtration core 6 and caulking groove
12 are interference fitted, and for 12 relative limit slot 10 of caulking groove, play the role of fixed filtration core 6.
Radial clearance between the filter chamber 1 and filter gland 2 is equipped with sealant rubber ring 13, protects internal cavities
Air-tightness is held, while has both anti-skidding effect, that is, prevents the loosening of filter gland 2 from skidding off.
Using labyrinth seal structure 14, labyrinth seal structure 14 is for the filter chamber 1 and 2 joint of filter gland
It is continuous indentation for joint, like step shape, makes air generating throttle effect by continuous narrow and small gap to reach
A kind of structure of seal, principle are the existing knowledge of association area.
The filter chamber 1 forms air guide column 15, conventional exhaust hole 4 and 1 end of filter chamber by gas vent 4 is axially extending
Face flushes, thus gas vent 4 export air-tightness protection again need to add labyrinth or obturator, add production cost and
Manufacturing procedure.
The beneficial effects of the utility model：A kind of new multistage composite air filtering structure filter provided by the utility model
Core is multistage filtering, and air filtration is abundant, device one end connection air compressor, high negative promotion filter efficiency, in structure
Evade air leakage without filter core problem, enhancing reduces noise ability, and cost is relatively low, three-stage filtration, but structure assembly is integrated,
Installing and dismounting is simple, easily implements, using grade-safe material, it is safe to use, can clear water cleaning, pollution storage capacity is also excellent
In existing single-stage filtering product.
