Description
Technical field
The present invention relates to technical field of water purification, in particular to a kind of efficient PAP composite filter element.
Background technique
Existing water purifier generallys use the combination of three-level independence filter flask+filter core to be filtered in the market, wherein filter core
Generally use the structure of PP cotton cladding active carbon particle and extruded activated carbon.There are pipeline complexity to account for for the filtration system of multi-stage filter
The disadvantages of pollution rear class filter core is precipitated is easy with the carbon dust that space is big, replacement filter core number is frequently and in prime filter core.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of efficient PAP composite filter elements, only need a filter core that can reach
To the effect of three-stage filtration, it is not necessarily to multi-stage pipeline, without frequent replacement.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of efficient PAP composite filter element, including be rolled into
Outer layer PP cotton, middle layer active carbon and the internal layer PP cotton of tubular, three layers of close contact；The filtering accuracy of the outer layer PP cotton is greater than interior
The filtering accuracy of layer PP cotton, the middle layer active carbon are pressed by several Carbon fibe laminations.
Further, the filtering accuracy of the outer layer PP cotton is 5 microns, with a thickness of 8mm or more.
Further, the filtering accuracy of the internal layer PP cotton is 1 micron, with a thickness of 5mm or more.
Further, the middle layer active carbon is mainly by 1500 ㎡ of specific surface area/g or more activated carbon fibre lamination and cotton
Yarn composition, with a thickness of 10mm or more.
Further, the axial length of the middle layer active carbon is equal to the axial length of the outer layer PP cotton, the internal layer
The axial length of PP cotton is less than the length of the middle layer active carbon；The axial ends of the internal layer PP cotton forms mounting hole.
It further, further include the end cover matched with the mounting hole, the end cover includes being connected
Inner wall, outer wall and ring cowling, the inner and outer wall are each perpendicular to an end face of the ring cowling, another end face of the ring cowling
Upper setting is fluted, is embedded gasket in the groove.
Further, annular gear is provided on the inner peripheral surface of the inner wall.
Further, the end cover is by being integrally formed.
Compared with prior art, a kind of efficient PAP composite filter element provided by the invention, the outer layer PP including being rolled into tubular
Cotton, middle layer active carbon and internal layer PP cotton, three layers of close contact by the first step coarse filtration of outer layer PP cotton, then arrive active carbon layer
Processing organic pollutant, fine filtering is finally carried out by the PP cotton of internal layer again, a filter core is realized and reaches three-stage filtration
Effect, and existing water purifier filter flask in the market can be compatible with, reduce the quantity of pipeline and filter flask in water purifier, the full mistake of product
Filter core only needs replacing once, will not impact to subsequent water quality.
Detailed description of the invention
Fig. 1 is sectional side elevation of the invention；
In figure：10- outer layer PP cotton, the middle layer 20- active carbon, 30- internal layer PP cotton, 40- end cover, 41- inner wall, outside 42-
Wall, 43- gasket, 44- annular gear, 45- mounting hole.
Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
As shown in Figure 1, a kind of efficient PAP composite filter element provided by the invention, including be rolled into tubular outer layer PP cotton 10, in
Layer active carbon 20 and internal layer PP cotton 30, three layers of close contact；The filtering accuracy of outer layer PP cotton 10 is greater than the filtering of internal layer PP cotton 30
Precision, middle layer active carbon 20 are pressed by several Carbon fibe laminations.
Specifically, (filtering accuracy is the aperture in hole to the filtering accuracy of outer layer PP cotton 10, only allows the particle less than the precision
Pass through) it is 5 microns, with a thickness of 8mm；The filtering accuracy of internal layer PP cotton 30 is 1 micron, with a thickness of 5mm；Middle layer active carbon 20
It is mainly made of 1500 ㎡ of specific surface area/g activated carbon fibre lamination and cotton yarn, with a thickness of 10mm.It is 12mm's with diameter
Rod-shaped grinding tool rolls internal layer PP blanket, take out internal layer PP blanket by non-woven fabrics and ACF activated carbon fibre lamination stack at bilayer along
The outer surface crimped of internal layer PP blanket is finally rolled up outer layer PP blanket, is finally made.
Its working principle is that：Water flow enters from outer layer PP cotton surface, and hydrophobic area maximizes, because outer layer crimps, so edge
Filter core radius be directed toward center of circle direction density it is increasing, hole is closer and closer, thus the filtering accuracy of outer layer PP cotton outside be in
Now outer the characteristics of dredging interior close needle design, it stops the mode of particle to be gradual reduced during the filtering of outer layer PP cotton
Precision to be filtered, eliminates muddy and effective guarantee middle layer active carbon absorption efficiency, water flow continues from outside to inside by middle layer active carbon,
Active carbon just not interference of the particle of bulky grain when adsorbing organic matter particle absorbs the efficiency highest of organic matter particle at this time
(middle layer is rolled using the activated carbon fibre blanket of bigger serface plus cotton yarn enhancement layer, and absorptive capacity is particle
5-10 times of active carbon is the high 5- of granular activated carbon for the adsorbance of inorganic matter, organic substance and heavy metal ion in water
6 times, it is for the highest selection of absorbent-type filter material cost performance that filtration resistance is small and the advantages such as recoverable)；Last flow direction internal layer
PP cotton filtering layer, cyclic annular internal layer is using the higher blanket of compactness, the powdered carbon for further filtering thinner impurity and falling off on a small quantity, effectively
Protect and ensure the using effect of very high degree of precision filter core and service life below.
The axial length of middle layer active carbon 20 is equal to the axial length of outer layer PP cotton 10, and the axial length of internal layer PP cotton 30 is small
In the length of middle layer active carbon 20；Mounting hole 45 is formed between the corresponding middle layer active carbon of the axial ends of internal layer PP cotton,
Mounting hole 45 and end cover cooperation fasten.
End cover 40 is integrally formed using food grade materials, and end cover 40 includes the inner wall 41 being connected, outer
Wall 42 and ring cowling, inner and outer wall are each perpendicular to an end face of ring cowling, be arranged on another end face of ring cowling it is fluted, it is described
Gasket 43 is embedded in groove, gasket 43 can prevent water flow from passing through from the gap between layer.It is arranged on the inner peripheral surface of inner wall
There is annular gear 44, can be convenient from both ends and clamp internal layer PP cotton and intermediate active charcoal.
In conjunction with attached drawing, the embodiments of the present invention are described in detail above, but the present invention is not limited to described implementations
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
