Description
Technical field
The invention belongs to filter core technical field, more particularly to a kind of filter core and the multistage composite filter core being made up of the filter core.
Background technology
A large amount of filter cores for using are integrated form water purification catridge in the purifier of domestic water at present, its various filtrate of collection
In one, with multi-filtering effect, and space availability ratio can be improved, reduce filter cylinder quantity, reduce production cost.But,
In existing integrated form water purification catridge, if the failure of certain material for core needs to change, whole filter core is changed, also will
The multiple material of filter body is changed simultaneously, so that cause the waste of other available filter materials.
To solve the above problems, in the market is occurred in that by multiple small filter core boxes filter cartridge construction in series, a upper filtering
Penetrating passage is connected between layer bottom and next filter layer top, to increase the globality of filter cartridge construction, above-mentioned several small filter cores
Using a mandrel connect for being arranged on centre together, this structure has the drawback that because there is hole at the center of filter core box box,
Sealing between filter material and mandrel it is difficult to ensure that, easily there is the phenomenon that water and filter material directly flow down along mandrel, it is impossible to protect
Demonstrate,prove the clean-up effect of water.
In addition, the filter core that the high-precision filter inside for being applied to the industrial circles such as oil, chemical industry is installed is universal
It is required that filter core length is big, linearity is good, quick, strainability stabilization easy to assembly.It is existing to be installed on the one of filter interior
Secondary shaping filter core limited length (being shorter than 1.2m mostly) long, and length is all the short filter core weldering of multistage in the overlength filter core of more than 1.2m
Connect and form, but existing overlength filter core cannot meet quick docking, accurate positioning, easy for installation etc. and require, have a strong impact on life
Produce efficiency；Nor different size, the independent assortment of the filter core of different size can be realized according to the treating capacity of waste water.
In order to overcome disadvantages mentioned above, the positive innovation research of the present inventor, to create a kind of new filter core and by this
The multistage composite filter core of filter core composition.
The content of the invention
The multistage composite filter core constituted the present invention solves the technical problem of a kind of filter core of offer and by the filter core, should
The equal heeling-in in two ends of filter core has connector, can according to liquid waste processing amount, independent assortment different size, various sizes of filter core,
Meet traffic demand, the length to composite filter element is not limited, and is combined as needed completely, and can be realized in anabolic process
Rapid abutting joint, accurate positioning, it is easy for installation, significantly improve production efficiency.
In order to solve the above technical problems, one aspect of the present invention is：A kind of filter core, including filter core sheet are provided
Body and connector, the filter element body are the middle cylindrical cartridge body with a cavity, and the cavity is from the filter core sheet
The lower end of body extends to the through hole of upper end, the connector there are two and be imbedded at respectively the upper end of the filter element body and under
End, the connector is the stepped tubular connector being formed by connecting by top tube and down tube, and the internal diameter of the down tube and described
The external diameter of upper pipe matches, and the external diameter of the down tube matches with the cavity of the filter element body, positioned at filter element body upper end
The upper pipe of connector protrudes from the upper end of the filter element body.
In order to solve the above technical problems, the further technical scheme that the present invention is used is：
The filter element body is PP filter element bodies.
Further say, the down tube that the upper pipe of the connector has external screw thread, the connector has and the outer spiral shell
The internal thread that line matches.
Further say, positioned at the upper end of step surface and the filter element body of the connector of the upper end of the filter element body
Face flushes, and the lower surface positioned at the down tube of the connector of the lower end of the filter element body is neat with the lower surface of the filter element body
It is flat.
Further say, on the outer surface of the connector and be imbedded at the position of the filter element body and set along its length
There are some circumferential lines being intervally arranged.
Further say, the circumferential lines of the connector and its outer surface is injection moulding integrated molding part.
Further say, the filter element body is cylindrical filter cartridge body.
A kind of multistage composite filter core being made up of described filter core, including filter core described at least two for being sequentially connected in series, and
The upper pipe of the connector of the upper end of filter core described in next stage is connected with the down tube of the connector of the lower end of filter core described in upper level.
Further say, the upper surface of filter core described in next stage flushes with the lower surface of filter core described in upper level and closely pastes
Close.
The beneficial effects of the invention are as follows：Advantages of the present invention at least have it is following some：
First, the two ends of filter core of the invention are embedding the connector being adapted, and can realize identical or different thickness filter
Core, the combination of identical or different length filter core, the real flow realized completely according to treatment fluid, independent assortment filter core, to combination
The length of composite filter element afterwards does not have any limitation；
2nd, the outer surface of the connector of filter core of the invention is provided with circumferential lines, during liquid waste processing, typically by filter core periphery
Water inlet, the cavity water outlet in the middle of filter core, in this case, filter core circumferential water feed produces hydraulic pressure, due to that with circumferential lines, can increase
Plus the frictional force of connector surface and filter core inwall, and then increase the sealing between filter core and connector, will not be because of sealing not
Leak well, it is ensured that clean-up effect；
3rd, multistage composite filter core of the invention, by the step surface and filter element body of the connector positioned at filter element body upper end
Upper surface flush, the lower surface of down tube positioned at the connector of filter element body lower end flushes with the lower surface of filter element body, energy
The seamless connection of multistage composite filter core is enough realized, there is the filtration yield saved space or be effectively increased in the confined space,
And the installation direction to filter core is not limited, both can vertically install, it is also possible to be transversely mounted, strong applicability；
4th, multistage composite filter core of the invention, because the connector of each filter core is screw element, need to only screw i.e. during assembling
Can, it is not necessary to simple, convenient, fast by special instrument, and with filter core docking do not misplace, installs deflection it is small, product
The advantages of product entirety linearity is good；
5th, multistage composite filter core of the invention, it is convenient due to combining and splitting, in its partial destruction, it is not necessary to overall
Change, need to only change the filter core of damage, not only Renewal process is simple and convenient, save replacement cost, and filter core can be saved
Material cost.
