Power, and it can be prevented to be lost from filter structure, promote filter core service life.
Detailed description of the invention
Fig. 1 is the partial cross-sectional structural diagram of the application direct drinking filter core one embodiment.
Specific embodiment
The technical solution of the utility model is described in detail in the following with reference to the drawings and specific embodiments, but it is described
The explanation of embodiment, only a part of the embodiment of the utility model, wherein most are not limited to that.
The utility model proposes a kind of receiving containing carbon fiber cladding organic and inorganic reticular structure for direct drinking filtering
The multi-layered filtering element structure of rice material, referring to Fig. 1, the structure of the filter core is the composite filter of hollow tubular, the two of hollow tube
End setting first end cover 4 and second end cover 5.The composite filter includes the ultrafiltration composite membrane 1 set gradually from inside to outside, inhales
Attached layer 2, PP cotton filter layer 3, outermost layer are that antibacterial PP cotton material constitutes PP cotton filter layer 3, and middle layer is to contain organic and inorganic net
The absorbing carbon fiber enclosure material of shape structure nano material constitutes adsorption layer 2, opens up in the first end cover and/or the second end cover
For the outlet of filtered direct drinking outflow, hollow tube is for the filtered direct drinking outflow of composite filter.Unfiltered water
It should be flowed into from the outside of outside antibacterial PP cotton material 3, via the absorbing carbon fiber enclosure material of organic and inorganic reticular structure nano material
2 adsorption filtrations, then filtered via ultrafiltration composite membrane 1, last filtered direct drinking is flowed out by intermediate hollow.
The application has the advantage that novel organic-inorganic reticular structure nano material is used for direct drinking filtration system, and
And can effectively prevent nano material and leak, effluent characteristics and filter element life are influenced, there is stronger application prospect.
In one embodiment of the utility model, the first end cover and the second end cover are annular, are bonded in institute
State the both ends of hollow tube.For example, the first end cover and the second end cover open up the first opening and the second opening respectively, it is described
The aperture of first opening and second opening is consistent with the internal diameter of the hollow tube.Preferably, the first end cover and described
Second end cover can be used antibacterial PP cotton material and be made.
In one embodiment of the utility model, the both ends of the PP cotton filter layer 3 respectively with the first end cover and
The seamless close adhesion of second end cover, the both ends of the ultrafiltration composite membrane 1 respectively with the first end cover and the second end
Cover seamless close adhesion.Accommodation space, first end cover 4 are formed between the PP cotton filter layer 3 and the ultrafiltration composite membrane 1
The accommodation space is sealed with second end cover 5, for filling the carbon fiber adsorption containing organic and inorganic reticular structure nano material
Material.
In one embodiment of the utility model, the carbon fiber containing organic and inorganic reticular structure nano material
