Description

A kind of diatom ooze porous composite ceramic filter core

Technical field

The present invention relates to a kind of water or air filter, particularly a kind of water or air purifier filter core.

Background technology

Along with the raising of the day by day serious and people's living standard of environmental pollution, air purifier, drinking water purifier have been come into huge numbers of families, and the core filtration, purification parts of this two product are filter core.

Traditional filter core is filter net type, in order to reach good filter effect, often adopts the structure of the stack of multistorey strainer mesh, and this filter core volume is large, and filter effect is also undesirable.

Publication number is that the file of CN 1094988A discloses a kind of composite ceramic filter core, its technical scheme adopting is that the U-shaped filter core of a back-off is installed in the enclosure, in U-shaped filter core, be filled with active carbon, first running water enters U-shaped filter core, by the filtration of active carbon, U-shaped element wall, finally enter in shell, the filter cartridge construction of this structure is comparatively simple, and filter effect is obviously improved, but its filter area is little, if increase filter area, the inevitable increase that brings again small product size.

China Patent No. is that 200920109614.8 patent document discloses a kind of air purifying filter core, the mode that it adopts traditional filter screen to be combined with honeycomb type ceramic filter, the two ends of honeycomb type ceramic filter connect, on ceramic filter surface, be provided with coating, the filter core of this structure does not still solve the bulky defect of filter screen filter core, and particularly, ceramic filter air directly enters from one end of ceramic filter, from the other end, discharge, filter effect is poor.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of simple in structurely, volume is little, and filter area is large, the diatom ooze porous composite ceramic filter core that filter effect is desirable.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of diatom ooze porous composite ceramic filter core, comprise filter core main body, in described filter core main body, be provided with the through hole of some perforations, between described through hole, form filter wall, wherein the lower end of a part of through hole is sealed and is formed into phase hole by lower end cap, and the upper end of remainder is sealed and formed phase hole by upper plug head.

Described through hole is to be the square hole that matrix form distributes.

Describedly enter phase hole and go out phase span to arrange.

In described through hole, be filled with adsorbing medium.

The surface deposition of described filter wall or be attached with noble metal catalyst layer.

The invention has the beneficial effects as follows: filter core of the present invention is composite porous through pugging by diatom ooze, extruding, high-temperature firing forms, there is hole many, hole wall is thin, surface area is large, corrosion-resistant, intensity is high, hole density is high, be the advantages such as crystal arrangement, product hole remains on below 2.5 microns, adopt honeycomb, in product use procedure, can reach the ventilation of instructions for use, utilize the physical characteristic of material itself, can be more effective and the combination of three-element catalytic technique, can one-time validity filter or catalytic decomposition water or airborne peculiar smell, formaldehyde, the pernicious gases such as chemistry volatile matter, dust, smog, the solid particles such as PM2.5.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described.

Fig. 1 is filter core sectional view of the present invention;

Fig. 2 is the cutaway view of A-A direction in Fig. 1.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of diatom ooze porous composite ceramic filter core, comprises the filter core main body 1 being formed by diatom ooze porous composite ceramic material sintering.Diatom ooze porous composite ceramics is a kind of porous filter material that is widely used as air or water filtration purposes in prior art, such as China Patent No. or application number are the disclosed diatom ooze of patent document (diatomite) the porous composite ceramicses such as " 200910112074.3 ", " 201310255131.X " etc., filter core main body 1 forms through pugging, extruding, high-temperature firing, have that hole is many, hole wall is thin, surface area is large, corrosion-resistant, intensity is high, hole density is high, be the advantages such as crystal arrangement, product hole remains on below 2.5 microns.

In described filter core main body 1, be provided with the through hole of some perforations, between described through hole, form filter wall 2, wherein the lower end of a part of through hole forms into phase hole 5 by lower end cap 4 sealings, the upper end of remainder forms phase hole 6 by upper plug head 3 sealings, lower end cap 4, upper plug head 3 can be after throwing complete, fill end at through hole, then sintering forms, also can be after sintering completes, adopt the fillings such as bonding mode to form, the thickness of lower end cap 4, upper plug head 3 is less, firmly sealing and be advisable.

Filter core main body 1 integral body of the present invention is cylindrical, through hole is along the axially-aligned of filter core main body 1, through hole is to be the square hole that matrix form distributes, describedly enter phase hole 5 and go out phase hole 6 to be spaced, adopt this structure, the air or the water that enter in phase hole 5 can be discharged to the phase hole 6 that goes out on four limits by four sidewalls simultaneously, and four sidewalls that go out phase hole 6 also can enter phase hole 5 from four and obtain water or the air filtration simultaneously, can effectively improve the efficiency of filtration.

The present invention adopts honeycomb, in product use procedure, can reach the ventilation of instructions for use, owing to entering He Chuxiang hole, phase hole, not to be directly communicated with, the air or the water that enter in phase hole can only just can enter out phase hole by the filtration of filter wall, on filter type, be similar to permeable membrane fine filtering, diatom ooze porous composite ceramics itself has very strong high temperature resistant in addition, corrosion resistance and mechanical strength, can in through hole, fill adsorbing medium as active carbon etc., also (nearly all noble metal is useful as catalysts all can or to adhere to noble metal catalyst layer at the surface deposition of filter wall, conventional have platinum, palladium, rhodium, silver, ruthenium etc., three-element catalytic specification requirement carrier can be acidproof, high temperature resistant), utilize the physical characteristic of material itself, can be more effective and the combination of three-element catalytic technique, the disposable effective filtration of energy or catalytic decomposition water or airborne peculiar smell, formaldehyde, the pernicious gases such as chemistry volatile matter, dust, smog, the solid particles such as PM2.5.
