Description

Water purifier with active carbon filter core

Technical field

The utility model belongs to filtering material technical field, and in particular to the water purifier with active carbon filter core.

Background technology

At present, chlorine is added in running water, as a kind of cost-effective sterilizing means, by the world more than 80% Water factory uses.A certain amount of chlorine residue must be kept in municipal tap water, to ensure the microbiological indicator of drinking water safety.It is and such Disinfectant has that obvious penetrating odor, mouthfeel are poor, and DBPs also has unfavorable shadow to health under long-term behavior Ring.Therefore, it is very necessary using the chlorine residue in water purifier removal drinking water and penetrating odor and improvement mouthfeel.It is existing net The material that the chlorine residue that hydrophone is gone in water removal mainly uses is activated carbon.And the basic principle that activated carbon removes chlorine residue is physical absorption And chemisorbed.Wherein physical absorption is mainly that the micro-porous adsorption of activated carbon corresponds to the chlorion of pore size and played a role； Chemisorbed is that carbon reacts with hypochlorous acid and generates hydrochloric acid and carbon dichloride, the activity and participation of the extent of reaction and carbon The quantity of reaction determines.It is granular activated carbon filter core to remove chlorine residue main product in the market, uses the production of 8-20 mesh mostly Product, external surface area is smaller, and chlorine residue clearance is usually less than 90%, and total flux is relatively low.Active carbon filter core product has two major classes：Post Shaped activated carbon filter core and bulk type active carbon filter core.Column-shaped active carbon filter core is lived using the coal mass active carbon and coconut husk of gel powder with high adsorptive Property charcoal as filter material, be subject to the adhesive column compression molding of food-grade or directly formed by a firing by high temperature.Column is lived One layer of non-woven fabrics for having filtration is respectively wrapped in inside and outside property filtration core, it is ensured that charcoal core does not fall out powdered carbon, charcoal core in itself Equipped with soft nitrile rubber sealing gasket, charcoal core is loaded filter cylinder has good sealing at both ends.Bulk type active carbon filter core Required activated carbon granule is fitted into special plastic casing, end cap is welded on to the both ends of the surface of housing with welding equipment, The both ends of housing are respectively put into the non-woven fabrics filter disc of filtration, it is ensured that charcoal core does not fall out powdered carbon and Heisui River when in use. According to the needs of client, housing end plug can make the connector of different model, and its interface mode has：Flat-crushing type, duct type.In day During normal use, manufacturer substantially by the way of gluing, so and its easily makes when end cap is installed at activated carbon both ends Dropped into end cap degumming, reduce the adsorption effect of activated carbon.And for more high-quality sintering activity charcoal, even if end cap glue Water is not come off in itself, but intensity itself is not high due to sintering activity charcoal, and activated carbon is easily caused during use and is opened in itself Split and come off, equally reduce the adsorption effect of activated carbon.Therefore how to provide one kind avoids end cap from coming off, and ensures active carbon filter core The column-shaped active carbon filter core of filter effect the problem of being those skilled in the art's urgent need to resolve.PP cotton filter cores also known as fusion-jet type PP Filter core, using nonpoisonous and tasteless polypropylene particles, by heating melting, spinneret, traction and manufactured tubulose filter core.It is if former Material is based on polypropylene, it is possible to is referred to as the molten blown filters of PP, it integrates surface, deep layer, coarse-fine filter；It is big, resistance to flow Corrode the features such as high pressure resistant, inexpensive.Also there is the situation of composite filter element, generally after individual layer filter core completes, then incite somebody to action both It is combined together, gap is between each other present and easily loosens, reliability is poor, have impact on strainability.Such as Chinese patent CN201020540658.9 " a kind of granular active carbon compound filter element " disclose it is a kind of including hollow cylindric composite filter element, set Put the capping being connected respectively at composite filter element both ends and with composite filter element both ends, the composite filter element includes coaxial package and contour The outer melt-blown filter of cylindrical hollow and interior melt-blown filter, the inner surface of the outer melt-blown filter and the outer surface of interior melt-blown filter The activated carbon granule of bulk is provided with the space formed between being covered with both ends, the activated carbon granule forms closely knit activated carbon Adsorption layer.

Utility model content

In order to overcome above mentioned problem and defect existing for water purifier in the prior art, the utility model is to active carbon filtration The water purifier of core is improved and innovated, provide it is a kind of increase surface area, reliability it is good, it is lifting strainability based on The NEW TYPE OF COMPOSITE water purification catridge of micro mist sintering activity charcoal.Technical scheme is used by the utility model solves technical problem：Band The water purifier of active filtration core, including, composite filter element, the composite filter element includes, skeleton, the milipore filter of filling in skeleton, The active carbon layer sintered with the micro mist of skeleton outer cladding, and the PP cloth in the active carbon layer outer cladding.

Further, the skeleton is stainless steel ring skeleton.

Further, the surface of the skeleton is provided with treatment hole.

Further, the thickness of the skeleton is 2-5mm, and the thickness of the active carbon layer is 10mm-20mm, the PP cloth Thickness is 5mm-10mm.

Further, the milipore filter includes the inlet opening on surface and internal ultrafiltration membrane filaments.

Further, the particle diameter of the micro mist activated carbon is the mesh of 200 mesh -500.

Further, the aperture of the active carbon layer is less than the aperture of PP cloth.

Further, density is to successively decrease from high to low to the PP cloth from inside to outside.

Further, the PP cloth is from inside to outside successively by high density layer of meltblown fibers, Midst density layer of meltblown fibers and low close Spend layer of meltblown fibers composition.

Water purifier of the utility model with active carbon filter core provides combined filter element, combines milipore filter, activated carbon The advantages of filter layer and PP melt-blown filters, the filter layer that the skeleton of filter core is inside and outside with it form one, sound construction.Should The self-supporting ability of filter core is strong, high mechanical strength, service life length, and replacing filter core speed is fast, can bear certain pressure, energy Used under severe operating mode, use range is wide, while also ensure that higher filtering accuracy.

The technical solution of the utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
