Background Art

A stirrer is a device that forces convection and uniform mixing of liquid and gaseous media. It is often used when different substances need to be mixed in industrial production, such as the production of coatings. Since coatings are usually mainly resins, oils, or emulsions, with or without pigments, fillers, and corresponding additives, and are prepared as viscous liquids with organic solvents or water, they need to be stirred and mixed in a reaction tank during production. During the stirring process, the mixed materials need to be quickly stirred to melt and mix them. However, in the prior art, the mixed materials are usually stirred at room temperature, and the fluidity of the mixed materials at room temperature is poor, so there are problems such as low stirring efficiency and poor stirring effect. In addition, since the driving shaft of the stirring driving device needs to extend into the reaction tank, and because the sealing of the reaction tank as a whole needs to be ensured, the driving shaft of the stirring driving device inevitably contacts the surface of the reaction tank. Due to the large friction between the two, a large amount of heat is easily generated under the long-term high-speed rotation of the driving device, resulting in excessively high temperature in the tank, increased pressure, and even a safety risk of causing explosion.
