Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a centrifugal stirring device of a mixer. Background Art

[0002] A mixer is a device used for mixing, stirring, homogenizing or accelerating chemical reactions. It can achieve mixing and stirring in liquid, solid or gaseous materials, and is widely used in the production process of chemical, pharmaceutical, food processing, environmental protection and other fields. For some high-viscosity or difficult-to-mix materials, the centrifugal stirring device can provide stronger stirring force to ensure that the materials are fully mixed, so a centrifugal stirring device of a mixer is needed.

[0003] When a centrifugal stirring device of an existing mixer is in use, a motor is used to drive the centrifugal barrel to rotate, so that the additives entering the centrifugal barrel are subjected to centrifugal motion. Therefore, all the additives are constantly moving, and then the stirring mechanism is driven to rotate and revolve around the rotation center of the centrifugal barrel through a linkage mechanism to continuously stir the moving additives. Through a motor, the additives can be subjected to both centrifugal motion and continuous stirring by the stirring mechanism, thereby improving the uniformity of stirring and shortening the stirring time.

[0004] However, when using this method, the inside of the centrifugal barrel cannot be cleaned while stirring. Since the inner wall cannot be cleaned, some materials will remain on the inner wall of the device during the stirring process. As time goes by, these residual materials will gradually accumulate, causing contamination or cross-contamination of the next batch of products. The residual materials on the inner wall will affect the mixing effect of the next batch of products, resulting in uneven mixing or unstable quality. This will affect the quality and performance of the product and increase the scrap rate in the production process. Utility Model Content

[0025] Start the motor 4, the output end of the motor 4 is connected to the shaft 5. When the motor 4 is started, the shaft 5 starts to rotate. The rotation of the shaft 5 further drives the rotation of the driving pulley 6. Through the connection of the belt 7, the rotation of the driving pulley 6 is transmitted to the driven pulley 8. When the two driven pulleys 8 rotate, they will drive the stirring rod 9 to rotate. The rotation of the stirring rod 9 not only drives the rotation of the fixed ring 10, but also makes the stirring blade 11 start working. The stirring blade 11 is designed to effectively mix the materials during the stirring process to ensure The material can be evenly distributed. When the rotating shaft 5 rotates, it also drives the rotation of the mounting block 12. The rotation of the mounting block 12 further drives the rotation of the fixing frame 13.
