BACKGROUND ART Conventionally, A-paddle (flat blade) blades, inclined blade blades, and right-angled turbine blades are often used in a single-stage or multi-stage form as stirring blades of a stirrer. 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 can reach the tank wall as shown in Fig. 14. The collision generates a circulating flow that moves 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 high viscosity liquids and liquids containing solids that tend to settle at the bottom of the tank, C-straddle type blades and anchor type blades are used. Furthermore, a D-spin blade is often used to dissolve solids in liquids. In the agitator using the above-mentioned stirring blades B, C, and D, the gap between the outer end of the blade and the tank should be reduced to prevent adhesion to the tank wall, move the liquid, and shear and scrape the liquid with the blade. to achieve mixing and other purposes in the tank. This stirrer is used at relatively low blade rotation speeds.

When the conventional stirring blade A is used in a single stage as shown in Fig. 14, it is assumed that a plurality of baffle plates are arranged at intervals from the bottom to the top on the tank wall surface to promote the generation of circulating flow. However, the mixing time is quite long while requiring a large stirring power, 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 were used in multiple stages, there was a disadvantage that the exchange of liquid between each stage was small and the mixing characteristics could not be improved. The conventional agitators B and C had the disadvantage that they were 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 there is an inconvenience that a complete mixing state cannot be achieved in a short time. .

化、混合する作用を有する。 As shown in FIG. 9, unlike the conventional paddle blade (FIG. 11), the bottom paddle 7 is disposed in sliding contact with the bottom of the stirring tank 1, so that it can be used as a paddle blade, a horseshoe-shaped blade, or an anchor-type blade. It has both effects.
As shown in FIG. 10, the baffle plate 10 has the function of promoting the generation of liquid discharged to the tank side wall side by the bottom paddle 7 so that it does not move circularly but instead flows upwardly. Further, the arm portion 8 and the strip 9 of the lattice wing 6 are connected to the bottom paddle 7 and the baffle plate 10.
It has the effect of dividing and mixing the liquid circulating in the tank during its descending process.

The comparison test results show that the paddle blade (without baffle plate) has a width of 4 to 7 times, and the spiral ribbon blade has a width of 2 times, whereas the blade of the present invention (with a baffle plate) has a slightly wider width due to the ratio of its component parts. It was 1 to 1.3 times.

むことが分かる。 The first expression represents the mixing characteristics of the blades in the stirring tank.
There is an n.θ M to R e curve shown in Figure 1. In the figure, n・θ M is complete mixing time θ M (sec) and blade rotation speed n (1/sec)
It is a value specific to the blade multiplied by , and is called the mixing time, and is an index representing the mixing performance of the liquid by the blade (including tank conditions). R e is an index indicating the turbulence of the liquid due to the blades (including tank conditions), and is called the Ray noise number.
It is expressed as n・d 2・ρ/μ. Here, n: blade rotation speed (1/sec), d: blade diameter (m), ρ: liquid density (Kg/m 3 ), μ: liquid viscosity (Kg/m・sec). Furthermore, there is a N p to R e curve shown in FIG. 12 that represents the power performance of the blades in the stirring tank. In the same figure, N p
is an index expressing the power performance of the liquid due to the blades (including tank conditions), and is called the power number, P・gc/ρ・n 3・d 5
It is expressed as Here, P: Power (Kgm/sec, gc:
Unit conversion coefficient, ρ: liquid density (Kg/m 3 ), n: blade rotation speed (1/sec), d: blade diameter (m). The n·θ M to R e curve and N p to R e curve were obtained when D (tank diameter) = 1 m, d = 0.5 m, and ρ = 1000 Kg/m 3 . Using these curves,
When compared with R e = 500 with μ=0.5Kg/m・sec (=500c.p.) and n=1r.ps, the mixing time n・θ M
In the present invention (when H/D = 1.0), the value at point A is a = 16, and in the conventional case, the value at point C is c = 80. Therefore, the present invention can mix in 1/5 of the mixing time compared to the conventional method. Done, n=
It can be seen that even with a value of 1, there is a high mixing ability. Also,
The power number N p is the value e = 5 at point E in the present invention (when H/D = 1.0), and the value g = 8 at point G in the conventional case, so to create the state of R e = 500, When the required power value is calculated as P=N p・(ρ・n 3・d 5 )/g c , it is 15.94 for the present invention and 25.51 for the conventional method, which means that the present invention requires 1/1.6 of the stirring required compared to the conventional method. It turns out that it can be done with power.
また、混合前の液を同様のμ＝１／1000Kg／

て効率良く製品の歩留まりも良いことが分かる。 In addition, the liquid before mixing is similar to μ=1/1000Kg/
m・sec (1c.p.), the mixed liquid μ=0.5Kg/m・
sec (500c.p.), the mixing time n・θ M changes from point C0 to point C as the viscosity increases, and the amount of change in value c− c0 increases. However, the present invention (H/D
= 1.3), the value changes from point B0 to point B, and the amount of change in value b - b0 is almost zero, so from the start of stirring (low viscosity liquid) to the end of mixing (high viscosity liquid) It can be seen that the reactor has stable mixing characteristics, is efficient as a reaction tank, and has a good product yield.
さらには、第１３図に同じ完全混合時間θM

ができる。 Furthermore, Fig. 13 shows the same complete mixing time θ M
A comparison will be made between the conventional example and the example of the present invention regarding the required power corresponding to (sec). According to this, it can be seen that both the mixed liquid of 2000 c.p. and the mixed liquid of 1 c.p. of the present invention are significantly smaller than the conventional ones. Conversely, the present invention can obtain the same performance as the conventional one with a small amount of power.
