Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of reaction kettle, especially relates to a high -efficient curing agent reaction kettle. BACKGROUND

[0002] The reaction kettle is a container for physical or chemical reaction. Through the structure design and parameter configuration of the container, the functions of heating, evaporation, cooling and low-speed mixing are realized. The reaction kettle is mainly used for processing and treating curing agent.

[0003] The reaction kettle in the prior art usually comprises a kettle body, a jacket is arranged on the outer wall of the kettle body, a reaction cavity is arranged in the kettle body, and the temperature in the reaction cavity is usually cooled by the conduction of the fluid in the jacket to the kettle body wall. Since the heat transfer efficiency at the center position of the reaction cavity is much lower than that near the peripheral wall, there is a problem of uneven temperature in the reaction kettle, which makes it impossible to uniformly heat and cool the chemicals in the reaction kettle. Especially for chemical reactions with a large amount of heat release during the reaction, since the internal temperature can only be cooled by peripheral conduction, not only is the temperature uneven, but also the cooling time is long, which greatly reduces the reaction effect of the product and affects the product quality. Moreover, for curing agent products, different reaction temperatures, reaction pressures, reaction times of materials and reaction conversion rates have a direct impact. Some special material reactions must be carried out in a specific temperature range to achieve sufficient reaction, optimal conversion rate and reaction time. The operator exchanges heat by the conduction of the fluid in the jacket to the kettle body wall to realize the heating and warming of the cylinder body. The heating efficiency is slow, and the reaction efficiency needs to be improved. This makes the curing agent discharge uneven, which undoubtedly greatly reduces the production efficiency and quality. SUMMARY
