Abstract
The invention discloses a filter core for a tap-type water purifier and relates to the technical field of water purifiers, and especially relates to the technical field of the filter core on the water purifier. The filter core comprises a nano fiber crude filtering outer layer, a purifying medium filling zone and a nano fiber membrane fine filtering layer. The purifying medium filling zone is arranged in the nano fiber crude filtering outer layer, wherein one end of the nano fiber crude filtering outer layer is connected to the nano fiber membrane fine filtering layer. The filter core can be used for filtering harmful substances in water without external pressure required.
Description
Technical field
The application relates to the technical field of water purifier, particularly relates to the technical field of the filtration core on water purifier.
Background technology
The World Health Organization's investigation display: China has 300,000,000 people drinking sordid water, has 436 to be heavily polluted in 532 trunk rivers in the whole nation.
In recent years, China has the water contamination accident big and small more than 7000 to break out every year, the area related to comprises Shanghai, Zhejiang, Shandong, Fujian, Jiangsu, Guangdong, Guangxi, Jiangxi, Gansu etc. province, the dead pig event in such as Shanghai in 2013, Lanzhou tap water benzene pollution event; Zhenjiang water contamination accident in 2012 etc.This type of tap water pollutes the fear that accident often causes whole city.In addition, also highlight all the more in the safe water problem in the area that the disaster such as earthquake, flood occurs.
In order to solve water pollution issue, many scientific research institutions, environment-friendly type company all start to research and develop various water purifying plant.Apply comparatively general filtering material mainly contains PP cotton, carbon-point, RO film, hollow fiber ultrafiltration membrane, pottery etc. at present.But such filtering material, the filtering accuracy as PP cotton, carbon-point, hollow fiber ultrafiltration membrane, pottery etc. is lower, the objectionable impurities in water effectively can not be filtered; And the water of RO membrane filtration is pure water, not containing mineral substance, human body is drunk for a long time can affect HUMAN HEALTH, and RO water purifier also needs applying power auxiliary pressurized just can filter simultaneously, and this not only can waste electricity consumption, and there is the danger of wet environment electricity consumption.
Summary of the invention
The application's object be to provide a kind of can objectionable impurities in high efficiency filter water, faucet type water purifier filtration core without the need to impressed pressure.
A kind of faucet type water purifier filtration core, comprises nanofiber coarse filtration skin, purification medium fill area, nano fibrous membrane fine filtering layer; Described purification medium fill area is arranged in nanofiber coarse filtration skin; The outer field one end of nanofiber coarse filtration connects nano fibrous membrane fine filtering layer.
Reasonable, the nanofiber coarse filtration skin of the application is the one in pottery, PE, PP, PVDF.
Reasonable, be filled with in gac, calcium sulfite, KDF, medical stone in the purification medium fill area of the application one or more.
Reasonable, the nano fibrous membrane fine filtering layer of the application is the one in pottery, PE, PP, PVDF, PLA, PES, PAN, PTFE.
The application adopts technique scheme, and compared with prior art tool has the following advantages:
The faucet type water purifier nano fibrous membrane filtration core that the application relates to can be meticulous Filtered tap water in the harmful material such as chlorine residue, bacterium, virus, iron rust, red worm, micro/nano level particle, macromole, filtering accuracy is up to 99.9%, and filtering particle diameter can reach 1-10nm.Meanwhile, this filtration core can regulate the pore size of nano fibrous membrane filtration core according to demand, thus reaches the objectionable impurities in selective filter water, and retains the mineral element useful to human body.
Simultaneously, the hierarchical structure design of nano fibrous membrane can be carried out according to fractal theory, hierarchical structure nano fibrous membrane after optimization can allow the nano effect of nanofiber more obvious, namely this filtration core is while acquisition filtration efficiency, very low pressure reduction can be kept again, make filtration core that impressed pressure can not be needed just can effectively to filter by means of only hydraulic pressure, and guaranteed discharge is at more than 2L/min.
Accompanying drawing explanation
Fig. 1 is the structural representation of the application's nanofiber coarse filtration skin in cylindricality.
Fig. 2 is the structural representation of the application's nanofiber coarse filtration skin prominent fore-set shape in circle.
Embodiment
Be described in detail below in conjunction with the technical scheme of accompanying drawing to the application:

The application's device in use; first nanofiber coarse filtration skin 1 is prepared; again by the weighting material of filling gac (particle or fiber) in purification medium fill area 2, calcium sulfite, KDF, medical stone etc. can be used for adsorbing/remove chlorine residue, increase the effects such as human body trace quantity mineral substance element, removal heavy metal; finally nano fibrous membrane fine filtering layer 3 is combined with above-mentioned two portions; engagement thread can be adopted to connect; make the filtering accuracy of this faucet type water purifier filtration core higher; to nano level, but can retain again the trace element of needed by human body.
The shape of the nanofiber coarse filtration skin 1 of the application includes but are not limited to cylindricality, the prominent fore-set shape of circle etc., and material therefor includes but are not limited to pottery, PE, PP, PVDF etc., also can with nano fibrous membrane compound between two.
The purification medium fill area 2 of the application, the weighting material that its inner stuffing includes but are not limited to gac (particle or fiber), calcium sulfite, KDF, medical stone etc. can be used for adsorbing/remove chlorine residue, increase the effects such as human body trace quantity mineral substance element, removal heavy metal.
Nano fibrous membrane fine filtering layer 3 described in the application, its material includes but are not limited to pottery, PE, PP, PVDF, PLA, PES, PAN, PTFE etc.
Nano fibrous membrane fine filtering layer 3 described in the application, its hierarchical structure includes but are not limited to the unitized construction filter core of same (nanofiber pattern of the same race, diameter, material etc.) nano fibrous membrane, (nanofiber pattern not of the same race, diameter, material etc.) not of the same race nanofiber rete, and the non-woven fabrics also comprising above-mentioned nano fibrous membrane and different size or material carries out the nanofiber membrane cartridge of compound.
