Description
Technical field
The utility model relates to the water purification technology field, is specifically related to a kind of polypropylene and extruded activated carbon composite water-purification filter element.
Background technology
The polypropylene water purification catridge is first filtration unit common in all kinds of water purifiers, and it is mainly used in the tiny solid granule foreign in filtered water.The gac water purification catridge usually filters as last together, is used for the chemical substance of planar water, can decolouring, deodorizing, improve the water quality mouthfeel.But single filter core can't be realized the dirty effect of receiving of high requirement and adsorptive power simultaneously; In addition, the cracked situation about coming off of carbonaceous material can appear in the gac water purification catridge under filtered water stream shearing force and filtration pressure difference effect, thereby makes the new tiny solid granule foreign of introducing in water.Therefore prior art has proposed the technology of composite water-purification filter element, realizing the combination for the treatment of capacity and processing accuracy, and overcomes the cracked problem that comes off of carbonaceous material.
Patent documentation CN201799152U discloses a kind of granulated active carbon composite water-purification filter element; at first contour by two but cylindrical hollow formula polypropylene melt blown filters that radius is different carry out coaxial package; capping is added a cover at two ends; load activated carbon granule in the space that forms between the gap of two melt-blown filters and two ends capping; thereby both realized polypropylene melt-blown water purification catridge filteration; also realize the adsorption of gac water purification catridge, and overcome the cracked problem that comes off of carbonaceous material.
Use discovery by reality, the composite water-purification filter element that above-mentioned document provides is Shortcomings also: the cracked situation of carbonaceous material still can appear in activated carbon granule under filtered water stream shearing force and filtration pressure difference effect, cracked carbonaceous material of use initial stage can not break away from composite water-purification filter element owing to being subject to stopping of outer polypropylene melt blown filter and enter in water, but after normal temporal filtering, cracked carbonaceous material can enter into water by outer polypropylene melt blown filter gradually; And cracked carbonaceous material enters outer polypropylene melt blown filter can significantly reduce the water environment capacity of outer polypropylene melt blown filter, and causes filtration pressure difference increase, filtration efficiency to descend; In addition, its polypropylene melt blown filter layer of the disclosed composite water-purification filter element of above-mentioned document is carrying atypic activated carbon granule, so physical strength is not high.
Summary of the invention
The purpose of this utility model is to provide a kind of polypropylene and extruded activated carbon composite water-purification filter element, can improve the physical strength of composite water-purification filter element, and improve composite water-purification filter element receive dirty effect and work-ing life, and on the basis of original filter effect that do not detract, reduce production costs.
To achieve these goals, the technical scheme that the utility model proposes is:
A kind of polypropylene and extruded activated carbon composite water-purification filter element comprise core body and end cap; It is characterized in that: the non-woven fabrics that described core body is followed successively by coaxial package from the inside to the outside filters Intranet, extruded activated carbon, polypropylene melt-blown Filter column, non-woven fabrics filtration outer net; Described end cap is ring-type, and ring-type end cap inner edge filters Intranet with non-woven fabrics and is connected, and ring-type end cap outer rim is filtered outer net with non-woven fabrics and is connected.Internal layer uses non-woven fabrics to filter Intranet replacement polypropylene melt-blown Filter column of the prior art and can reduce costs, and the filter core integral body after improvement still can keep the action effect of original filtration fine solid particle; In addition, filter outer net and can increase the dirty effect of receiving of filter core integral body increasing layer of non-woven fabric in polypropylene melt-blown Filter column outside, and prevent that aging material for core breaks away from filter core contaminated filter water, thereby extended the work-ing life of filter core.
As the further improved polypropylene of the utility model and extruded activated carbon composite water-purification filter element, it is characterized in that: described extruded activated carbon is hollow circular cylinder by the hot melt adhesive compressing and shaping.By add hot melt adhesive in activated carbon granule, and make the gac setting by adding thermo compression, and can improve the physical strength of activated carbon column, reduce the cracked of carbonaceous material, and reduce gac to the carrying reactive force of polypropylene melt blown filter layer, thereby further extend the work-ing life of filter core.
As the further improved polypropylene of the utility model and extruded activated carbon composite water-purification filter element, it is characterized in that: it is bonding by hot melt adhesive that described ring-type end cap inner edge and non-woven fabrics filter Intranet, ring-type end cap outer rim and non-woven fabrics filtration outer net.
As the further improved polypropylene of the utility model and extruded activated carbon composite water-purification filter element, it is characterized in that: described non-woven fabrics filters Intranet and non-woven fabrics filtration outer net is that polypropylene material is made.
As the further improved polypropylene of the utility model and extruded activated carbon composite water-purification filter element, it is characterized in that: described end cap is that polypropylene or ABS resin material are made.
The polypropylene that the utility model provides and extruded activated carbon composite water-purification filter element can improve the physical strength of composite water-purification filter element; Can improve the physical strength of activated carbon column, reduce the cracked of carbonaceous material, and reduce gac to the carrying reactive force of polypropylene melt blown filter layer; Can improve the dirty effect of receiving of composite water-purification filter element and work-ing life; And can on the basis of original filter effect that do not detract, reduce production costs.
