Abstract
The invention discloses a nested composite filter core. The nested composite filter core comprises a first-stage filter core and a second-stage filter core which are mutually and coaxially nested and have hollow cylinder shapes, wherein the first-stage filter core passes through and is arranged in the bore of the second-stage filter core, the first-stage and second-stage filter cores have a same height, and the external diameter of the first-stage filter core matches with the internal diameter of the second-stage filter core; and both ends of the first-stage and second-stage filter cores are respectively provided with a cover seal, and the cover seals of the first-stage and second-stage filter cores are tightly combined together through gaskets to form the composite filter core. Two different filter materials can be simultaneously provided when the composite filter core is used, so the two filter materials with different functions are combined together to realize a case that filter requirements of the two filter materials can be satisfied through only using a filter; and the two stage filter cores can be individually replaced, so the whole replacement of the filter cores is avoided, thereby the service life of the whole composite filter core is prolonged, and the use cost is reduced.
Description
Technical field
The present invention relates to a kind of Filters, relate in particular to a kind of folded formula composite filter element.
Background technology
Filter core has obtained widespread usage as the Filters in the liquid handling process, but because the filter area and the filter core volume of filter core are a pair of contradiction; Can't be met simultaneously; So produced folded formula filter cartridge construction,, reduced the resistance that fluid flows to increase the unit filter area of filter core.But because the filter course of folded formula filter core still is one deck, so filtering accuracy is single, can't satisfy the requirement of particular filter; Simultaneously, in big flow and high accuracy filtration treatment, the life-span of filter core is shorter; Thereby cause use cost higher; And when using single Filters, the Filters of difference in functionality need be installed different filter cores, and is loaded on respectively in the different filters; Thereby increased usable floor area, be unfavorable for installing.
Summary of the invention
In order to overcome above-mentioned defective, the present invention provides a kind of folded formula composite filter element, adopts two-layer composite that two kinds of filtering accuracies are provided, and because of can independently changing the service life that has prolonged whole filter core each other, has reduced use cost and has been beneficial to installation.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of folded formula composite filter element comprises first and second grade filter core that is hollow cylindrical of mutual coaxial package; Said first order filter core is arranged in the endoporus of second level filter core; Height such as this first and second grade filter core, and the internal diameter of the external diameter of first order filter core and second level filter core is complementary; These first and second grade filter core two ends all are provided with cap seal, and combining closely through packing ring between the cap seal of this first and second grade filter core fuses, and then is combined into a composite filter element, and the two-stage filter core can be changed separately.
As further improvement of the present invention, said first order filter core is the extruded activated carbon filter core, and said second level filter core is a kind of in foldable filter element and the fabric filter element.
As further improvement of the present invention, said first order filter core is made up of the cap seal that first filter material and the sealing shroud of hollow cylindrical is located at the ring-type at these first filter material two ends, is installed with a packing ring respectively on the inside and outside lateral margin of this cap seal; Said second level filter core by second filter material of hollow cylindrical, fixedly be close to the cap seal that inner frame and fixed cover on the second filter material endoporus wall be located at the ring-type at this second filter material and inner frame two ends and form; When said first order filter core was arranged in the endoporus of second level filter core, this first filter material was inserted in the said inner frame, and the packing ring on the cap seal lateral border of this first order filter core and the cap seal medial margin of second level filter core are combined closely.
As further improvement of the present invention, the pore size filter of said second filter material is greater than the pore size filter of first filter material, and promptly first order filter core is smart filter filter body, and second level filter core is the coarse filtration filter body.
As further improvement of the present invention, said cap seal, inner frame are all the plastic of single injection-molded.
The invention has the beneficial effects as follows: combining closely through packing ring between the cap seal of first and second grade filter core fuses; And then be combined into a composite filter element; During use two kinds of different filtering materials can be provided simultaneously; Say that from function foldable filter element and fabric filter element can be removed silt, suspension, colloid and the iron rust in the water; Active carbon filter core can be removed materials such as peculiar smell in the water, chlorine residue, halogenated hydrocarbons; The filter material of such two kinds of difference in functionalitys combines, and only needs to use a filter, just can satisfy the filtration requirement of two kinds of filter materials; And the two-stage filter core can be changed separately; Thereby avoided the whole replacing of filter core, prolonged the service life of whole filter core, reduced use cost.

Fig. 1 is a STRUCTURE DECOMPOSITION sketch map of the present invention.
The specific embodiment
Embodiment to folded formula composite filter element of the present invention is elaborated with reference to the accompanying drawings.
Folded formula composite filter element of the present invention comprises first and second grade filter core that is hollow cylindrical of mutual coaxial package; Said first order filter core is arranged in the endoporus of second level filter core; Height such as this first and second grade filter core, and the internal diameter of the external diameter of first order filter core and second level filter core is complementary; These first and second grade filter core two ends all are provided with cap seal 3, and combining closely through packing ring 4 between the cap seal 3 of this first and second grade filter core fuses, and then is combined into a composite filter element, and the two-stage filter core can be changed separately.
Said first order filter core is the extruded activated carbon filter core, and said second level filter core is a kind of in foldable filter element and the fabric filter element.
In the present embodiment, first order filter core is made up of the cap seal 3 that first filter material 1 and the sealing shroud of hollow cylindrical is located at the ring-type at these first filter material, 1 two ends, is installed with a packing ring 4 on the inside and outside lateral margin of this cap seal 3 respectively; Second level filter core by second filter material 2 of hollow cylindrical, fixedly be close to the cap seal 3 that inner frame 5 and fixed cover on second filter material, the 2 endoporus walls be located at the ring-type at this second filter material 2 and inner frame 5 two ends and form; When said first order filter core was arranged in the endoporus of second level filter core, this first filter material 1 was inserted in the said inner frame 5, and the packing ring 4 on the cap seal lateral border of this first order filter core is combined closely with the cap seal medial margin of second level filter core.
