Description

Technical Field

[0001] The utility model relates to the field of silica gel production, in particular to an efficient automatic stirring device for silica gel mixing. Background Art

[0002] Silica gel mixing requires stirring mainly because stirring can ensure the uniform mixing of silica gel and curing agent, avoiding uneven curing or the situation of dry surface but wet inside. Stirring ensures that all components are evenly distributed throughout the mixture, which is crucial for the performance and quality of the final product. If the silica gel mixing involves chemical reactions, stirring helps to promote the reaction, ensuring sufficient contact between reactants and the uniformity of the reaction. Stirring is a basic operation in the silica gel production process and is crucial for ensuring product quality and performance.

[0003] After retrieval, the Chinese patent publication number: CN215428514U discloses a stirring device for silica gel production. By turning on the servo motor, the servo motor drives the rotation of the rotating shaft, the rotating shaft drives the stirring rod to rotate, the stirring rod drives the rotating disk to rotate, and the rotating disk drives three groups of stirring blades to rotate. The stirring blades stir the raw materials for silica gel production inside the stirring tank, realizing the rapid and efficient mixing of the stirring device for the raw materials for silica gel production and improving the processing efficiency of the stirring device.

[0004] In the above technical solution, the servo motor is used to drive three groups of stirring blades to rotate and stir the raw materials. However, more heat is generated when stirring high-viscosity liquids because more energy is required to overcome the internal resistance of the liquid, and the heat generated by stirring is difficult to dissipate. High temperature may affect the color stability of silica gel, resulting in color change or fading. At the same time, the heat will change the viscosity of the mixture, affecting the subsequent processing and forming processes. Therefore, an efficient automatic stirring device for silica gel mixing is proposed to solve the above problems. Summary of the Utility Model
