Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As depicted in figs. 1 and 2, the invention provides a kind of filter core, the hard screen pack 20 comprising filter element body 10 and be sheathed in filter element body 10.Wherein, filter element body 10 is supported in hard screen pack 20 inside.
By arranging hard screen pack 20, cushioning effect can be played by above-mentioned hard screen pack 20 pairs of current, in current scour process, deformation occurring to prevent filter element body 10.Meanwhile, above-mentioned hard screen pack 20 can also filter the large granular impurity in water, prevents above-mentioned large granular impurity to be adsorbed on filter core, thus can improve the service life of filter core.
It should be noted that, hard screen pack 20 in the present embodiment can disassemble from filter element body 10, and this hard screen pack 20 can be reused after rinsing, thus add the service life of filter core, and then prevent filter element body from causing secondary pollution to environment.
Filter core also comprises fixation kit 30, is arranged at the end of filter element body 10 and coordinates with hard screen pack 20, hard screen pack 20 and filter element body 10 to be compressed.
Arranging fixation kit 30, can to utilize said modules that filter element body 10 and hard screen pack 20 are coordinated more tight, prevents the two disconnected from each other and have an impact to clean-up effect in purification run process.
Particularly, the auxiliary section 32 that above-mentioned fixation kit 30 comprises component body 31 and is connected with component body 31, auxiliary section 32 extends along the direction away from component body 31, 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 element body 10, and above-mentioned auxiliary section 32 extrudes with the hard screen pack 20 be set in filter element body 10 and coordinates, to be pressed in filter element body 10 by above-mentioned hard screen pack 20.
Preferably, the two ends of above-mentioned filter element body 10 are provided with above-mentioned fixation kit 30, come off from any one end of filter element body 10 to prevent hard screen pack 20.
Further, said modules body 31 can also be provided with mounting groove, filter core also comprises the black box 40 be arranged in mounting groove.Black box 40 is set, installs so that above-mentioned filter core is coordinated with other assemblies, prevent 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 meeting above-mentioned requirements all should within the protection domain of the application.
The pore size of the filter bores of the hard screen pack 20 in the present invention is a, and the pore size of the filter bores of filter element 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, stainless steel filtering net parcel PP cotton (hereinafter referred to as PP composite filter element) that can adopt 20 microns is research object, studies this compound PP filter core to the protective effect of PP cotton.This experiment is the cotton dirty stifled Acceleration study of PP mainly, and preparation granule density is about the muddy water of 3g/L, and situation is blocked up in the dirt of comparing compound PP filter core and PP filter core (supporting without screen pack).Experimental result is as follows: in compound PP filter core, and 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, the PP needing replacing three new is cotton.Therefore, contrast, to the protective effect of PP cotton clearly, can filter out the most bulky grains in water, speed is blocked up in the dirt delaying PP cotton to the stainless steel filtering net of 20 microns, thus greatly can extend the life-span of PP cotton, reduces water purification cost.
In general, the aperture of filter screen should be a bit larger tham the cotton aperture of PP, is advisable with 10-50 micron, should be not excessive or too small, and excessive will causing effectively can not tackle bulky grain, too small, and filter screen can be caused to need frequently to scrub.
Present invention also offers a kind of filter, comprise above-mentioned filter core.Wherein, above-mentioned filter core uses as first order filter, and correspondingly with second level filter connects.
From above description, can find out, the above embodiments of the present invention achieve following technique effect: by arranging hard screen pack, cushioning effect can be played to current by above-mentioned hard screen pack, thus prevent filter element body from current scour process, deformation occurring, meanwhile, above-mentioned hard screen pack can also filter the large granular impurity in water, prevent above-mentioned large granular impurity to be adsorbed on filter core, thus the service life of filter core can be improved.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
