Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a chemical safety reaction vessel. Background Technology

[0002] In a broad sense, a reaction vessel is a stainless steel container used for physical or chemical reactions. The structural design and parameter configuration of the container are determined according to different process requirements. The design conditions, processes, inspection, manufacturing, and acceptance must be based on relevant technical standards to achieve the heating, evaporation, cooling, and low- to high-speed mixing reaction functions required by the process. Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation.

[0003] After a period of use, impurities and debris will accumulate on the stirring components of the reactor. Most existing stirring components are integrated, which makes cleaning the stirring components very complicated and inefficient. In addition, the pressure in the reactor is high, and the stirring blades will wear down when they collide with the materials during the stirring process. The integrated installation means that the entire stirring component needs to be replaced when the stirring blades are replaced, which increases the production cost. Utility Model Content
