Abstract
The utility model provides double filter layers filter core, described filter core by coaxial package and contour double filter layers form, comprise the micropore ceramic filter layer of internal layer and outer field PP melt blown filter layer, the surface spraying of micropore ceramic filter layer has photocatalyst film, PP melt blown filter layer is for raw material shapingly forms antibacterial PP melt blown filter layer through melt-blown with antibacterial PP, micropore ceramic filter layer and PP melt blown filter layer link together, the two ends up and down of described filter core are also provided with upper cover and lower capping, and upper and lower capping and filter core hot melt are integrated.This filter core combines the advantage of PP melt-blown filter and micropore ceramic filter element, has the advantage that filtering accuracy is high, flux is large, mechanical strength is high, and has antibacterial functions.
Description
Technical field
The utility model belongs to filtering material and device field, relates to double filter layers filter core.
Background technology
Filter core can be divided into the kinds such as paper filter core, chemical fibre filter core, ceramic element, active carbon filter core according to the difference of material, and different filter cores has different features, is combined by the filter core of multiple unlike material, can play the advantage of each filter core.Melt-blown filter belongs to the one of chemical fibre filter core, take polypropylene as the efficient filter core of one that raw material employing melt-blown process is prepared from, there is the advantages such as filtering accuracy is high, flux is large, but its bad mechanical strength, self-supporting performance are bad, and conventional melt-blown filter also do not have antibacterial functions.
Summary of the invention
The purpose of this utility model is to provide double filter layers filter core, and this filter core combines the advantage of PP melt-blown filter and micropore ceramic filter element, has the advantage that filtering accuracy is high, flux is large, mechanical strength is high, and has antibacterial functions.
The utility model solves the technical scheme that its technical problem adopts:
Double filter layers filter core, described filter core by coaxial package and contour double filter layers form, comprise the micropore ceramic filter layer (1) of internal layer and outer field PP melt blown filter layer (2), the surface spraying of described micropore ceramic filter layer (1) has photocatalyst film, described PP melt blown filter layer (2) links together for antibacterial PP melt blown filter layer, described micropore ceramic filter layer (1) and PP melt blown filter layer (2).
Preferably, the two ends up and down of described filter core are also provided with upper cover (3) and lower capping (4), and described upper cover (3) and lower capping (4) are integrated with filter core hot melt.
Preferably, described antibacterial PP melt blown filter layer with antibacterial PP for raw material shapingly to form through melt-blown.
Preferably, described antibacterial PP be adopt application number be 201310252794.6 patent of invention announce method be prepared from.
The beneficial effects of the utility model have:
(1) this filter core comprises double filter layers, and internal layer is micropore ceramic filter layer, and skin is PP melt blown filter layer, can improve mechanical strength and self-supporting ability on the one hand, can improve filtering accuracy on the other hand;
(2) surface spraying of micropore ceramic filter layer has photocatalyst film, there is the effect of antibiotic and sterilizing, and PP melt blown filter layer shapingly to form through melt-blown for raw material with antibacterial PP, also has good antibacterial action, so impart antibacterial functional of this filter core.
accompanying drawing illustrates:
Fig. 1 is the structural representation of utility model filter core.
In figure, 1. micropore ceramic filter layer, 2.PP melt blown filter layer, 3. upper cover, 4. descends capping.
Detailed description of the invention
As shown in Figure 1, double filter layers filter core, described filter core by coaxial package and contour double filter layers form, comprise the micropore ceramic filter layer (1) of internal layer and outer field PP melt blown filter layer (2), the surface spraying of described micropore ceramic filter layer (1) has photocatalyst film, described PP melt blown filter layer (2) links together for antibacterial PP melt blown filter layer, described micropore ceramic filter layer (1) and PP melt blown filter layer (2).
The two ends up and down of described filter core are also provided with upper cover (3) and lower capping (4), and described upper cover (3) and lower capping (4) are integrated with filter core hot melt.
Described antibacterial PP melt blown filter layer with antibacterial PP for raw material shapingly to form through melt-blown.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendment, on an equal basis replacement and improvement etc. done within spirit of the present utility model and principle, all should drop within protection domain of the present utility model.
