[0002] Concentrated sulfuric acid is an important chemical raw material widely used in industrial production. However, concentrated sulfuric acid is highly corrosive and dangerous. If not handled properly during unloading, it can easily leak, which not only wastes raw materials but may also cause safety accidents, posing serious hazards to operators and the environment.

[0003] Currently, the traditional method of unloading concentrated sulfuric acid mainly relies on manual operation, which involves directly connecting the unloading pump through a hose. After each unloading, a certain amount of concentrated sulfuric acid remains in the hose. Furthermore, manual operation makes it difficult to accurately control the unloading progress, which can easily lead to the splashing of concentrated sulfuric acid and pose a safety hazard to the operators.
