Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a chemical reaction kettle convenient for cleaning. Background Technique

[0002] A reaction kettle is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are realized. Reaction kettles are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food, and are pressure vessels used to complete processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation, such as reactors, reaction pots, decomposition pots, polymerization kettles, etc.

[0003] At present, when the existing chemical reaction kettle is in use, the materials inside it will adhere to the kettle wall. When these materials cool down, they will stick tightly to the kettle wall and are difficult to remove.

[0004] After retrieval, a scraping-wall reaction kettle with the patent publication number CN211411997U includes a kettle body. A stirring shaft is provided at the top of the kettle body. The stirring shaft includes a base, and an accommodating cavity is opened in the base. A stirring device is provided on the stirring shaft. The stirring device includes a stirring connecting rod with one end arranged in the accommodating cavity, stirring blades arranged on the stirring connecting rod, and a scraping plate in contact with the inner wall of the kettle body arranged on the stirring blades. An adjusting cavity communicating with the accommodating cavity is opened in the stirring shaft. The above patent has the following deficiencies: In the prior art, when removing the materials attached to the inner wall of the reaction kettle, the scraping plate is often driven by the rotation power equipment of the reaction kettle itself to perform the cleaning operation. However, such a cleaning method is often worse than the cleaning effect of the cooperation of water and the scraping plate. The materials scraped by the scraping plate cannot be completely cleaned, which will affect the subsequent processing operations. To solve the above problems, we propose a chemical reaction kettle convenient for cleaning. Content of the Utility Model
