[0002] A reaction kettle is a device used for physical or chemical reactions. Through the structural design and parameter configuration of the container, it realizes functions such as heating, evaporation, cooling, and mixing at low and high speeds. Reaction kettles are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food, and are pressure vessels for completing processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation. Reaction kettles can be divided into different categories according to materials and designs, including carbon steel reaction kettles, stainless steel reaction kettles, glass-lined reaction kettles, steel-lined PE reaction kettles, steel-lined PTFE reaction kettles, etc. Each type of reaction kettle has its unique application scenarios and advantages. For example, stainless steel reaction kettles have good corrosion resistance and mechanical properties and are suitable for most chemical reactions. The structure of a reaction kettle generally consists of a kettle body, a transmission device, a stirring device, a heating device, a cooling device, and a sealing device. The design and selection of the stirring device depend on the properties of the reaction materials and the required stirring effect. The heating and cooling systems ensure that the reaction proceeds under suitable temperature conditions. The design of the sealing device is crucial for preventing leakage and maintaining the reaction pressure.

[0003] Currently, when the existing reaction kettles are in use, due to the presence of reaction materials inside, after the reaction materials are heated and reacted inside the reaction kettle, the materials will adhere to the inner wall of the reaction kettle, which is difficult to clean, increasing the labor burden of personnel and affecting the use efficiency of the reaction kettle. Based on this, a novel laboratory reaction kettle is proposed. Content of the Utility Model
