Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and in particular to a self-cleaning circulating stirred reaction vessel for coating liquid production. Background Technology
[0002] A reaction vessel is a container used to carry out physical or chemical reactions. It consists of a vessel body, a lid, a stirrer, a heating or cooling device, and a sealing device. It is made of various materials, including stainless steel, enamel, and glass, and can be selected according to different reaction media and process requirements. It is widely used in the chemical, pharmaceutical, food, dye, and pesticide industries. It is suitable for various operations such as stirring, mixing, heating, cooling, polymerization, and vulcanization. By controlling the reaction temperature, pressure, and stirring speed parameters, the reaction process can be precisely controlled to ensure the safety and efficiency of the reaction. It is one of the core equipment for various chemical reactions in industrial production.
[0003] This circulating stirred reactor for coating liquid production is a specialized piece of equipment designed specifically for coating liquid production processes. It mainly consists of a reactor body, a stirring system, and a circulation device. The stirring device ensures uniform mixing and dispersion of the coating liquid raw materials within the reactor, while the circulation system enhances heat and mass transfer efficiency through directional material flow, ensuring uniform reaction temperature and component stability. The equipment is suitable for various processes in coating liquid preparation, including dissolution, dispersion, and polymerization, effectively improving the consistency and performance stability of the coating liquid. Simultaneously, the circulating flow reduces material deposition, providing an efficient reaction environment for large-scale coating liquid production. In traditional stirring paddle designs, flow blind zones are created in the corners or bottom of the reactor, leading to uneven dispersion of coating liquid components and affecting film-forming performance. In existing technologies, materials are pumped from the bottom of the reactor and transported through pipelines to the top nozzles for uniform treatment. However, in aqueous coating liquid systems, an uncleaned, damp environment inside the reactor is prone to bacterial or mold growth, affecting subsequent use. Utility Model Content
