Description

Technical Field

[0001] The utility model relates to the field of polymerization inhibitor modification, in particular to a polymerization inhibitor modification reaction device. Background Art

[0002] Inhibitor is an industrial auxiliary agent, usually used to prevent the progress of polymerization. Inhibitor molecules react with chain free radicals to form non-free radical substances or low-activity free radicals that cannot be triggered, thereby terminating the polymerization. According to the patent office database search, the publication number CN213886205U is a kind of inhibitor efficient modified reactor. The two stirring blades are driven to move and rotate by two L-shaped rods to stir the chemicals in the reactor back and forth, thereby improving the reaction efficiency, reducing the chemical reaction time, and thus reducing the working time. However, the inner wall of the reactor body will adhere to the inhibitor, which is not convenient for cleaning the inner wall of the reactor body, and the top cover cannot be automatically opened to remove the internal stirring blade for cleaning;

[0003] Therefore, it is necessary to invent a reaction device modified by an inhibitor. Utility Model Content
