[0044] Make one first stirring blade 6 and one first stirring rod 16; Figure 1 and Figure 5 As shown, the first stirring blade 6 is a long strip structure, in the form of a clockwise spiral, and the spiral curvature is consistent with the curvature of the inner wall of the upper tank body 5; there are four first stirring blades 6, which are distributed at equal intervals around the circumference, as shown in FIG. Figure 4 As shown, the two ends of the four first stirring blades 6 are connected by a sleeve, and the sleeve serves as a first stirring rod 16. The first stirring rod 16 is equipped with a bearing that cooperates with the second stirring rod 15. The specific number of the first stirring blades 6 depends on the size of the tank.
[0045] Fabricate one second stirring blade 7 and one second stirring rod 15; As Figure 1 and Figure 5 shown, the second stirring blade 7 is a strip-shaped structure, spiraling counterclockwise, and the spiral curvature is half of that of the first stirring blade 6; There are four second stirring blades 7 in total, and the specific quantity depends on the size of the tank body, and they are evenly distributed at equal intervals in a circle, as Figure 4 shown, both ends of the four second stirring blades 7 are connected to the second stirring rod 15, and the second stirring rod 15 is a cylindrical structure.
[0046] Fabricate one base 11; As Figure 1 shown, the main body of the base 11 is in a "冂"-shaped structure; As Figure 3 shown, at the horizontal center of the base 11, an oval groove matching the radian of the lower tank body 12 is opened.
