のである。[Detailed Description of the Invention] A [Object of the Invention] (1) Industrial Application Field The present invention is applicable to cases where liquid substances are stirred and mixed to obtain a uniform product, and where polymer compounds are mixed under stirring conditions. This relates to a stirring device used in reactions for manufacturing.
(2) 従来の技術
従来より撹拌装置は数多く用いられており、低
粘度液では、プロペラ、タービン、バドルが一般
的であり、高粘度液では螺旋帯翼（ヘリカルリボ
ン翼）スクリユー翼、錨型翼が一般的である。(2) Conventional technology Many stirring devices have been used in the past. For low-viscosity liquids, propellers, turbines, and paddles are common, and for high-viscosity liquids, helical ribbon blades, screw blades, and anchor-type stirring devices are commonly used. Wings are common.
特に高分子製造プロセスで、往々にして取り扱
う高粘度液は、低粘度液に比べて混合時間が極め
て遅いため、その撹拌装置選定如何により製品品
質を左右することにより、惧重を要するものであ
る。また、高粘度液の場合には、撹拌動力が大き
いため、省電力の点からも、効率のよい混合撹拌
装置の選定は重要である。 In particular, high viscosity liquids, which are often handled in polymer manufacturing processes, have extremely slow mixing times compared to low viscosity liquids, so product quality is affected by the selection of stirring equipment, which is a matter of concern. . Furthermore, in the case of high viscosity liquids, since the stirring power is large, it is important to select an efficient mixing and stirring device from the point of view of power saving.
混合の効率からみて、撹拌装置に望まれる機能
は、
(i) 槽内全域を流動させる機能（循環機能）
(ii) 槽内全域にわたり剪断速度を均一に分散させ
る機能（剪断速度分布の均一化機能）
(iii) 液のマクロな入れ換えを推進する機能（液の
置換機能）
である。 In terms of mixing efficiency, the desired functions of a stirring device are: (i) the ability to flow throughout the tank (circulation function); (ii) the ability to evenly distribute the shear rate throughout the tank (uniform shear rate distribution); (iii) A function that promotes macroscopic liquid replacement (liquid replacement function).
そこで、従来の代表的な高粘度用撹拌装置と、
上記３つの機能を対応させると、螺旋帯翼では、
上記(i)の機能は満足しているが、(ii)の機能は小さ

ーブ付スクリユー翼の場合も、螺旋帯翼とほぼ同
じであり、さらにまた、錨型翼では上記(i)〜(iii)の
いずれの機能も満足していなかつた。 Therefore, we decided to use a typical conventional stirring device for high viscosity,
Corresponding the above three functions, in a spiral band wing,
The function (i) above is satisfied, but the function (ii) is small and the function (iii) is medium, and the screw blade with a trough tube is almost the same as the spiral band blade. Furthermore, the anchor-shaped wing did not satisfy any of the functions (i) to (iii) above.
このように、従来は高粘度液の混合を効率的に
行ない得る装置はほとんど見当らなかつた。 As described above, until now, there have been almost no devices that can efficiently mix high viscosity liquids.

環機能が増加し、循環機能は十分に満足され
る。(2) Effect The present invention has the above-mentioned configuration as its gist. (a) Since the helical guide plate is provided inside the spiral band blade, the circulation rate is approximately 1.5 times higher than in the case of only the spiral band blade. Function increases and circulatory function is fully satisfied.
(イ) 螺旋帯翼、螺旋形案内板及び両者間で剪断が
生じるため、剪断速度分布の均一化機能が補強
される。(b) Since shear occurs between the spiral band blade, the spiral guide plate, and between them, the function of making the shear velocity distribution uniform is reinforced.
