[0002] In recent years, as the design and operation of domestic pure low-temperature waste heat power generation projects have become increasingly mature, many new dry cement production lines in China have added waste heat power stations. During the operation of waste heat boiler hot air pipes and other equipment, their inner surfaces are subjected to strong erosion and wear by high-speed, high-temperature, dust-containing airflows for a long time. The pipe walls are easily eroded and thinned, and may be perforated and leak, seriously affecting normal production. Therefore, it is necessary to carry out anti-wear and anti-corrosion treatment on their inner surfaces.

[0003] When protecting the existing waste heat power generation system pipelines from wear, they are usually applied manually to the inner wall of the pipeline. After a series of physical and chemical reactions, the strength and hardness of the ceramic bond are achieved after 3 days at room temperature. The use process is time-consuming and increases labor costs, and it cannot be put into use quickly. Utility Model Content

[0037] The diameter of the fixed disc 22 is larger than the diameter of the fixed column 21, and the fixed groove 24 is opened relative to the fixed disc 22;

[0038] When the fixed disc 22 is located inside the fixed groove 24, the fixed column 21 extends outward through the hollow annular groove 23, and the fixed disc 22 is restricted inside the wear plate 12 by the fixed groove 24;

[0039] The movable plate 26 is an arc-shaped structure, and the movable plate 26 and the first telescopic spring 25 are located inside the other end of the anti-wear plate 12;

[0040] When the fixed disc 22 is located inside the wear plate 12, the outer side of the fixed disc 22 is in contact with the outer side of the movable plate 26;

[0041] Working principle: when the prefabricated anti-wear plate 12 needs to be connected, the fixing column 21 and the fixing disc 22 are placed into the internal position of the anti-wear plate 12 through the slot 31, and the outer side of the fixing disc 22 is in contact with the outer side of the movable plate 26, and a moving force is applied to the anti-wear plate 12, so that the anti-wear plate 12 drives the fixing column 21 and the fixing disc 22 to enter the hollow annular groove 23, and the fixing disc 22 drives the movable plate 26 to move inward, and the inward movement of the movable plate 26 drives the first telescopic spring 25 to be compressed.
