[0002] Ammonium perchlorate is a highly corrosive and toxic chemical reagent, requiring special safety precautions during its storage and transportation. An ammonium perchlorate reactor is a container used for the chemical reactions during the production of ammonium perchlorate. The inner wall of the reactor is easily corroded, worn, and thinned, reducing its service life. Therefore, an internal lining structure is usually installed inside the reactor. For example, application number CN201220229940.4 discloses a reactor lining comprising a cylindrical lining tube with openings at the top and bottom, the lining tube being composed of several lining plates pivotally connected to each other. However, this device suffers from the problem of loose joints between the lining plates, and these joints are susceptible to corrosion, leading to incomplete closure between the lining plates and resulting in leakage.
