Description

Layered microporous ceramic filter tube

Technical Field

The utility model relates to a ceramic filter tube field, in particular to improve filter effect's layering micropore ceramic filter tube.

Background

The microporous ceramic filter pipe is widely used in the purification treatment process of waste water and waste gas in the chemical, metallurgical, thermal, coking and nuclear industries, etc., and is composed of a plurality of bridge arch-shaped open pores which are uniformly distributed in size and are mutually communicated, when fluid passes through the pores, suspended substances, colloidal particles, macromolecular organic matters, etc. in the fluid are intercepted and adsorbed in a microchannel, thereby achieving the effects of purification and filtration homogenization. The microporous ceramic filter pipe has the advantages of high strength, wear resistance, high temperature resistance, corrosion resistance, no pollution, uniform pore distribution, long service life and simple regeneration, and is particularly suitable for various gas and liquid filtration and flow state processes. At present, the micropore ceramic filter pipe is the filtration aperture of single size, and the problem that exists is: although the microporous ceramic filter pipe with large pore diameter has strong flow capacity but poor filtering effect, the microporous ceramic filter pipe with small pore diameter has limited flow capacity although good filtering effect, in addition, in order to enhance the filtering effect, a mode is also provided that a film is plated on the outer surface of the ceramic filter pipe, the main material of the film is an inorganic film or an ultrafiltration film, but in the processing process, the condition of uneven film thickness of the film is easy to occur, secondary firing is needed, the process is relatively complex, in addition, the film is very thin (generally less than 0.5 mm), and the film is easy to damage in the processes of long-term use after installation or back washing, acid washing and the like, and the service cycle of the ceramic pipe is not long.

SUMMERY OF THE UTILITY MODEL

To the problem that micropore ceramic filter tube exists among the above-mentioned prior art, the utility model provides a layering micropore ceramic filter tube that micropore aperture distributes rationally, circulation ability is strong, the filter effect is good.

The utility model provides a technical scheme that technical problem taken is: the utility model provides a layering micropore ceramic filter tube, includes the body, the body middle part is provided with and link up the axial circulation passageway of body, the outside of circulation passageway is provided with the filter layer, the filter layer includes inlayer and skin, is provided with the first filtration hole of a plurality of in the inlayer, is provided with the filtration hole of a plurality of second in the skin, and first filtration aperture is 0.1 ~ 10 mu m, and the second filters the aperture of hole and is 10 ~ 30 mu m, and inlayer and outer thickness ratio 2 ~ 3: 7 ~ 8.

Compared with the prior art, the utility model, change original microporous ceramic filter tube's single filter layer and filtration aperture into the filter layer and the filtration pore of two-stage, make the suspended substance who contains different particle sizes, colloidal particle, the waste water of impurity such as macromolecule organic matter is earlier quick through outer interception filtration back, the rethread inlayer filters tiny suspended particle, can not only improve the filter effect, and can also improve filtration efficiency, in addition, compare coating film microporous ceramic filter tube, processing technology is simpler, the processing cost is lower, the coating film inequality can not appear, do not need the secondary to burn till, also can not lead to ceramic pipe condemned problem owing to the local membrane damage appears.

Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be described in further detail below with reference to specific embodiments according to the accompanying drawings.

As shown in figures 1, 2, 3, microporous ceramic filter tube material mainly is aluminium silicate matter, clayey matter, corundum matter, quartzy matter, silicon carbide nature and diatomaceous earth matter etc, layering microporous ceramic filter tube, including body 1, the body middle part is provided with and link up axial circulation passageway 2 of body, the outside of circulation passageway is provided with the filter layer, the filter layer includes inlayer 3 and skin 4, can carry out the multiple-layer filtration according to filtration strength and impurity content's difference, is provided with the first filtration pore 5 of crossing of a plurality of in the inlayer, is provided with a plurality of second filtration pore 6 in the skin, and the aperture of first filtration pore is 0.1 ~ 10 mu m, and the aperture of second filtration pore is 10 ~ 30 mu m, and inlayer and outer thickness ratio 2 ~ 3: 7 ~ 8, and waste water is followed outer filtration earlier and is got into the inlayer again, flows out in the circulation passageway. In addition, according to different filtering modes, the wastewater can enter the flow channel firstly and then flow out of the outer layer, the aperture of the first filtering hole in the inner layer is 10-30 mu m, the aperture of the second filtering hole in the outer layer is 0.1-10 mu m, and the thickness ratio of the inner layer to the outer layer is 7-8: 2-3. The wall thickness of the microporous ceramic pipe generally used for filtering industrial and domestic wastewater is 10-15 mm, and the length is 600-1000 mm.

The processing technology briefly describes that: the method comprises the steps of utilizing an inner layer die and an outer layer die, loading uniformly mixed wet materials between the middle layer die and the outer layer die for compression molding according to the shape required by the thickness and the size of the outer layer, then taking out the middle layer die, loading an inner layer die smaller than the middle layer die according to the shape required by the thickness and the size of the inner layer, loading the uniformly mixed wet materials between the inner layer die and the inner layer die for compression molding, slowly taking out the inner layer die at the same time, enabling the inner layer die to be a compact layered microporous ceramic filter tube blank body combined with each other, and then firing the blank body at a high temperature to form the ceramic.
