Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a chemical mixing reaction kettle. Background Art

[0002] Chemical production refers to the production process of using chemical methods to change the composition and structure of substances or to synthesize new substances. The products obtained from chemical production are called chemical products. Reactors are needed in the chemical production process. When mixing liquid materials, the reactor needs to use a premixing device to mix the liquid materials. Traditional premixing devices include components such as a stirring shaft, stirring blades, a feed cover and a feed port. Some reactants need to maintain a certain reaction temperature during the mixing process; however, existing reactors usually have electric heaters and refrigerators installed inside to adjust the reaction temperature. Although this method has a faster temperature change, it is easy to cause large fluctuations in the reaction temperature, and the temperature control effect is poor. Utility Model Content
