Abstract
The utility model provides a ceramic lining compensator, which is used in pipeline delivery systems in the industries such as mines, coal, metallurgy, building materials, chemical industry, environment protection and the like. The ceramic lining compensator is also named as an expansion joint or a telescopic joint. The ceramic lining compensator comprises a connecting tube and a honeycomb duct, wherein one end of the honeycomb duct (an initial end of medium flow) is connected with the connecting pipe (or other connection modes), the other end of the honeycomb duct forms a free state (or flexible connection), the inner wall of honeycomb duct is provided with a protective layer which is made of ceramic, and the ceramic which forms the protective layer is an abrasion-proof ceramic plate, an abrasion-proof ceramic tube or a self-propagating ceramic layer. The ceramic lining compensator solves the defects in a compensator of the prior art that the honeycomb duct is made of metal and is easily abraded under the effect of two phase media of high speed flowing air-solid (or liquid-solid), thereby becoming invalid. Compared with the prior art, the ceramic lining compensator has simple structure, materials of the working surface of over-current media are changed from metal into plastic, the abrasive resistance and the high-temperature resistant performance of the honeycomb duct are intensified, thereby greatly improving the service life of the compensator.
Description
Technical field
The utility model belongs to engineering element or field of components.Be applicable to the powder of industries such as thermal power generation, mine, coal, metallurgy, building materials and chemical industry and the conveying of slurries body.
Background technique
In the pipe-line transportation system of industries such as mine, coal, metallurgy, building materials, chemical industry and environmental protection, a large amount of using compensation devices also claim expansion joint or slip joint.It mainly acts on the displacement of the directions such as vertical, horizontal and angle that are bucking-out system.In the prior art, the honeycomb duct of compensator is generally metal material, under the effect of swiftly flowing gas-solid (perhaps liquid-solid) two phase mediums, and very easily wearing and tearing, thus lost efficacy.
Summary of the invention
Main purpose of the present utility model is to provide a kind of simple in structure at above-mentioned deficiency, and is wear-resistant, resistant to elevated temperatures ceramic-lined compensator.
Technical solution of the present utility model is: a kind of ceramic-lined compensator, comprise adapter, honeycomb duct, and it is characterized in that: the protective coating that the honeycomb duct inwall has pottery to constitute.
The pottery of the said formation protective coating of the utility model is wear-resistant ceramic sheet or wear resistance ceramic tube or spreads ceramic layer certainly.
Said from spreading the ceramic layer employing from spreading the method preparation.
Compared with prior art, the utility model is crossed the flow medium working surface and is become pottery by metal owing to adopt said structure, has strengthened the wear-resisting property and the resistance to high temperature of honeycomb duct, thus the working life of having improved compensator greatly.
Description of drawings:
Fig. 1 is two section bellow welding compensators; Fig. 2 is a single hop bellows flange articulated compensator.
Embodiment:
Among Fig. 1, with an end of metal honeycomb duct 3 (MEDIA FLOW to starting point) with take over 1 welding (or other connecting mode), the other end of honeycomb duct 3 (MEDIA FLOW to terminal) becomes free state (or being flexible coupling), paste the protective coating 4 that wear-resisting industrial ceramics sheet is formed in the inner wall surface of honeycomb duct 3, thereby the working surface that makes honeycomb duct becomes ceramic working surface, and then improves the working life of compensator.2 is bellows.5 is lower link bar.
Among Fig. 2, with an end of metal honeycomb duct 3 (MEDIA FLOW to starting point) with take over 1 welding (or other connecting mode), the other end of honeycomb duct 3 (MEDIA FLOW to terminal) becomes free state (or being flexible coupling), inner wall surface at honeycomb duct 3 is pasted the protective coating 4 that wear resistance ceramic tube constitutes, thereby make the working metal face of honeycomb duct become ceramic working surface, and then improve the working life of compensator.2 is bellows.5 is lower link bar.
Also can be from spreading ceramic layer at the protective coating 4 of the inwall of honeycomb duct 3, preparation is " self propagating high temperature is synthetic---centrifugation technique " from the method that spreads certainly that spreads ceramic layer, promptly utilizes exothermic reaction, forms the technology of composite ceramic layer at the steel pipe inwall.
Claims (2)
1, a kind of ceramic-lined compensator comprises adapter (1), honeycomb duct (3), it is characterized in that: the protective coating (4) that honeycomb duct (3) inwall has pottery to constitute.
2, a kind of ceramic-lined compensator as claimed in claim 1 is characterized in that: the pottery of said formation protective coating (4) is wear-resistant ceramic sheet, wear resistance ceramic tube or spreads ceramic layer certainly.
