Reference numeral in figure: 10, filter core body; 20, hard screen pack; 30, fixation kit; 31, component body; 32, auxiliary section; 40, black box.
The specific embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As depicted in figs. 1 and 2, the utility model provides a kind of filter core, comprises filter core body 10 and is sheathed on the hard screen pack 20 on filter core body 10.Wherein, filter core body 10 is supported in hard screen pack 20 inside.
By hard screen pack 20 is set, can play cushioning effect by 20 pairs of current of above-mentioned hard screen pack, to prevent that filter core body 10 from current scour process, deformation occurring.Meanwhile, above-mentioned hard screen pack 20 can also filter the large granular impurity in water, prevents that above-mentioned large granular impurity is adsorbed on filter core, thus the service life that can improve filter core.
It should be noted that, hard screen pack 20 in the present embodiment can disassemble from filter core body 10, and this hard screen pack 20 can be reused after rinsing, thereby increased the service life of filter core, and then prevented that filter core body from causing secondary pollution to environment.
Filter core also comprises fixation kit 30, is arranged at the end of filter core body 10 and coordinates with hard screen pack 20, so that hard screen pack 20 and filter core body 10 are compressed.
Particularly, above-mentioned fixation kit 30 comprises component body 31 and the auxiliary section 32 being connected with component body 31, and extend along the direction away from component body 31 auxiliary section 32, and auxiliary section 32 coordinates with hard screen pack 20.
The component body 31 of the fixation kit 30 in the present embodiment is oppositely arranged with one end of filter core body 10, and above-mentioned auxiliary section 32 coordinates with hard screen pack 20 extruding that are set on filter core body 10, so that above-mentioned hard screen pack 20 is pressed on filter core body 10.
Preferably, the two ends of above-mentioned filter core body 10 are provided with above-mentioned fixation kit 30, to prevent that hard screen pack 20 from coming off from any one end of filter core body 10.
Further, on said modules body 31, can also be provided with mounting groove, filter core also comprises the black box 40 being arranged in mounting groove.Black box 40 is set, so that above-mentioned filter core is coordinated to installation with other assemblies, prevents filtered leak of liquid.
Certainly, sealing assembly 40 can integrate with component body 31, so that install.
It should be noted that, the end cap that the fixation kit 30 in the present embodiment is made for rubber, certainly, this end cap also can adopt other materials to make, and every technical scheme that meets above-mentioned requirements all should be within the application's protection domain.
The pore size of the filter bores of the hard screen pack 20 in the utility model is a, and the pore size of the filter bores of filter core body 10 is b, wherein, and b < a.
It should be noted that, the filter bores size of the filter core in the present embodiment is 5-10 micron.
Particularly, can adopt the stainless steel filtering net parcel PP cotton (hereinafter to be referred as PP composite filter element) of 20 microns for research object, study this protective effect of compound PP filter core to PP cotton.This experiment is mainly the cotton dirty stifled acceleration experiment of PP, and preparation granule density is about the muddy water of 3g/L, the stifled situation of dirt of more compound PP filter core and PP filter core (supporting without screen pack).Experimental result is as follows: in compound PP filter core, to stainless steel filtering net, after three times are scrubbed, the aquifer yield of compound PP filter core can also return to initial 90%.And pure PP filter core aquifer yield sharp-decay, in 150L muddy water filtration experiment altogether, need to be changed three new PP cotton.Therefore, to recently seeing, the stainless steel filtering net of 20 microns to the protective effect of PP cotton clearly, can filter out the most bulky grains in water, delays the stifled speed of dirt of PP cotton, thereby can greatly extend the life-span of PP cotton, has reduced water purification cost.
In general, the aperture of filter screen should be a bit larger tham the cotton aperture of PP, with 10-50 micron, is advisable, should be not excessive or too small, and excessive will causing can not effectively be tackled bulky grain, and the too small filter screen that can cause need to frequently be scrubbed.
The utility model also provides a kind of filter, comprises above-mentioned filter core.Wherein, above-mentioned filter core is used as first order filter, and connection corresponding to second level filter.
