Description

Technical Field

[0001] The utility model relates to the technical field of ceramic wear-resistant elbows, in particular to a spliced ​​ceramic wear-resistant elbow. Background Art

[0002] Ceramic wear-resistant elbow is a kind of pipe fitting with excellent wear resistance. In industrial conveying systems, especially when conveying materials containing solid particles, ceramic wear-resistant elbow can greatly extend the service life of the pipeline system, reduce the frequency of maintenance and replacement, and reduce operating costs. It is widely used in material conveying pipelines in mining, electric power, metallurgy, coal and other industries.

[0003] Existing technologies include a utility model with publication number CN201014117Y, which discloses a spliced ​​ceramic wear-resistant elbow. The patent adopts a seamless elbow body with a wear-resistant ceramic lining on the inner wall. The wear-resistant ceramic lining is spliced ​​by multiple wear-resistant ceramic sheets, that is, the wear-resistant ceramic sheets are spliced ​​in a wedge shape in the circumferential direction to form a wear-resistant ceramic lining ring adapted to the inner wall of the seamless elbow body. Multiple groups of wear-resistant ceramic lining rings are axially connected and bent to form a wear-resistant ceramic lining adapted to the seamless elbow body. Retaining rings are respectively provided at the two ends of the seamless elbow body to block the wear-resistant ceramic lining. A high-temperature resistant inorganic adhesive is filled between the inner wall of the seamless elbow body and the wear-resistant ceramic lining, which solves the problem that traditional steel elbows have limited wear resistance and therefore a relatively short service life.

[0004] In the process of assembling spliced ​​ceramic wear-resistant elbows, there is a problem that existing ceramic elbows, such as the above-mentioned ones, use adhesives for bonding during splicing. Since the bonding parts of the ceramic pieces are exposed to the passing medium, after long-term use, the bonding parts are easily corroded by the passing medium, which then causes the ceramic pieces to fall off.
