れている。(Prior art) Conventionally, as the stirring blade of a stirrer, (A) paddle
- し・・ノ W Day is often used in single or multi-stage form. In the stirrer using these stirring blades (A), by increasing the rotational speed of the blade and increasing the flow rate of the liquid discharged in the radial direction from the outer end of the blade, the liquid flows to the tank wall as shown in Fig. 12. This generates a circulating flow that circulates upward and downward and returns to the blades, thereby mixing the inside of the tank. (B) Spiral blades and spiral ribbon blades are often used for high viscosity liquids. For highly viscous liquids and liquids that contain solids that tend to settle to the bottom of the tank (
0) Horseshoe-shaped tools and anchor-shaped tools are used. In addition, (D) pincushion blades are often used to dissolve solids in liquids. In agitators using these stirring blades (B), (0), and (D), the gap between the outer edge of the blade and the cypress is reduced to prevent adhesion to the tank wall, to move the liquid, and to shear the liquid by the blade. and scraping to accomplish mixing and other purposes in the tank. This agitator is used at a relatively low blade rotation speed.

都合があった。(Problems to be Solved by the Invention) When the conventional stirring blade (A) is used in a single stage as shown in FIG. Disturbing multiple books! Even if they are arranged at intervals, a large stirring power is required, the mixing time is quite long, and the power characteristics and mixing characteristics are poor. The mixing characteristics during low-speed rotation stirring are even worse. Even if the stirring blades (A) are used in multiple stages, there is little exchange of liquid between each stage.
There was a disadvantage that the mixing characteristics could not be improved. The conventional stirring blades (B) and (C) have the disadvantage that they are not effective for low viscosity liquids due to their structure. In addition, in the conventional stirring blade (D), the ability to discharge liquid from the outer end of the blade is very weak, and the phenomenon of liquid circulation and movement is difficult to occur, so it is inconvenient that a complete mixing state cannot be achieved in a short time. was there.

Comparing the state of Rθ=5DO with r, p, and s, the mixing time n・θy is the value a=16 at point A in the present invention (when H/D=1.0), and the value a=16 at point 0 in the conventional case. Since the value C=80, it can be seen that the present invention requires a mixing time of c115 compared to the conventional method, and has a high mixing capacity even when n=1. In addition, the power number Np is the value e = 5 at point E in the present invention (when H/D = 1.0), and the value g = 9 at point 0 in the conventional case, so the power number Np is Re = 5 (state of 10). The power value required to produce the current is determined by P=Np・(ρ・n3・d5)/gc, which is 15.94 in the present invention and 25.51 in the conventional case. It can be seen that the required stirring power is only 6.
