By arranging the second stirring rod into a bucket shape, the mixed liquid flowing down the wall can be spread into a film-like flow on the bucket surface, thereby increasing the contact area between the mixed liquid and the vacuum environment and improving the efficiency of vacuum degassing.

[0006] Preferably, by providing a stirring assembly with a first stirring rod, a second stirring rod and a third stirring rod with different structures and orientations, a better stirring effect can be achieved, and by providing a scraper, the material adhering to the inner wall can be scraped off, making it less likely to precipitate, and by providing a rotating assembly, the stirring tank assembly can be driven to rotate as a whole, thereby further increasing the fluidity of the internal material, thereby greatly improving the anti-precipitation effect, making the anti-precipitation effect better than that of traditional devices.

[0010] Beneficial effects of the utility model:

[0011] 1. Compared with the traditional vacuum mixer, the material is usually stirred by a stirring rod with a single structure, and the direction of the force is fixed, which is not convenient for generating multi-track motion and driving in different directions, resulting in a decrease in the mixing effect, insufficient friction and collision between particles, and easy precipitation. By setting a stirring assembly with multiple structures and a scraper, the material can be stirred more evenly, making it less likely to precipitate. By setting a first drive motor, the first rotating shaft can be driven to rotate, so that the first rotating shaft drives the first stirring rod, the second stirring rod and the third stirring rod to rotate and stir the material. By setting the first stirring rod, the second stirring rod and the third stirring rod with different structures and directions, the stirring material can be driven in from multiple directions, so that the mixing and stirring effect is better. By opening a guide hole on the first stirring rod, the second stirring rod and the third stirring rod, part of the material can pass through the guide hole to reduce the rotation resistance, and the fluidity of the material can also be increased, so as to further improve the stirring effect. During the rotation process, the first rotating shaft can also synchronously drive the scraper to rotate to scrape off the material adhered to the inner wall of the tank body, so that the material and the inner wall of the tank body continuously generate new interfaces, thereby improving the heat exchange efficiency and reducing precipitation.

[0012] 2. By setting a rotating component, the stirring tank component can be driven to rotate as a whole, thereby further increasing the fluidity of the internal material, thereby greatly improving the anti-sedimentation effect. By setting a second drive motor, the turntable can be driven to rotate to drive the second shaft to rotate, and then the second shaft drives the tank body to rotate synchronously so that the internal material further rotates to increase its fluidity. By setting multiple groups of support columns around the lower end side of the tank body, the tank body can be supported to increase the stability of the tank body. In the process of the second drive motor driving the tank body to rotate, the support columns slide along the arc groove, and the stirring component and the rotating component are double rotated inside and outside to make the stirring and mixing more uniform, thereby making the anti-sedimentation effect better. By setting an anti-slip pad at the lower end of the base to increase friction, it can play an anti-slip role, thereby making the support stability of the support component better, thereby ensuring the stable operation of the components above.

The second driving motor 301 can drive the turntable to rotate to drive the second rotating shaft 304 to rotate, and then the second rotating shaft 304 drives the tank body 101 to rotate synchronously, so that the internal material further rotates to increase its fluidity. The fluidity of the material is increased by setting a rotating component 3 to drive the tank body 101 to rotate as a whole, which can improve the anti-sedimentation effect. In the process of the rotating component 3 driving the tank body 101 to rotate, the support column 103 at the lower end of the tank body 101 slides around the arc groove 305 to support the tank body 101 synchronously.
