(2) An inclined blade is installed in one or both of both flows to generate the upstream and downstream. (3) Due to the above (1) and (2), A flow can be formed over the entire area, and a quick and highly efficient mixing can be achieved.
以下、図面にもとづいて本発明の実施例を説明する。 Embodiments of the present invention will be described below with reference to the drawings.
第１図及び第２図は、本発明に係る撹拌装置の１実施例
を示すものである。容器１内に回転軸２が挿入されてお
り、回転軸２には平板翼３及び傾斜翼４が取り付けられ
ている。平板翼３は、回転軸２の軸芯５に対して実質的
に平行に回転軸に取付けられその面積は、回転軸２の軸
芯５、容器内壁面６及び液面７で囲まれている断面積の
６０パーセント以上である。平板翼３の面積が６０パー
セントに満たないと、後記するように高い混合性能を発
揮することができない。また、傾斜翼４は回転軸２の軸
芯に対して傾斜角を持って回転軸に取付けられている。1 and 2 show one embodiment of the stirring device according to the present invention. The rotary shaft 2 is inserted into the container 1, and the flat blade 3 and the inclined blade 4 are attached to the rotary shaft 2. The flat plate blade 3 is attached to the rotary shaft substantially in parallel to the shaft core 5 of the rotary shaft 2, and its area is surrounded by the shaft core 5 of the rotary shaft 2, the container inner wall surface 6 and the liquid surface 7. It is 60% or more of the cross-sectional area. If the area of the flat blade 3 is less than 60%, high mixing performance cannot be exhibited as described later. Further, the inclined blade 4 is attached to the rotary shaft with an inclination angle with respect to the axis of the rotary shaft 2.
第３図は、第１図、第２図に示す撹拌翼を用いて高粘性
物質を撹拌した場合の容器の水平断面（第１図のII−II
部分の断面）方向の流動状態を示す。平板翼３が移動速
度１０で移動すると、外周部の流体は平板翼３に押さ
れ、同方向に移動するが、壁面６との間で生じる粘性抵
抗の影響により、外周部流体移動速度１１は、平板翼３
の移動速度１０に較べて小さな値となる。FIG. 3 is a horizontal cross-section of the container (II-II in FIG. 1) when a highly viscous substance is stirred using the stirring blades shown in FIGS. 1 and 2.
The cross-section shows the flow state in the direction. When the flat plate blade 3 moves at the moving speed 10, the fluid on the outer peripheral portion is pushed by the flat plate blade 3 and moves in the same direction, but the outer peripheral fluid moving speed 11 is , Flat blade 3
Is smaller than the moving speed 10 of.
その結果、平板翼３の移動に伴う流体の排斥体積と外周
部の流体の移動体積に差が生じその差が、半径方向の流
動を生じさせ、平板翼３近傍の半径方向内方への流体移
動速度１２として現れてくる。この半径方向内向きの流
れは、中心部に到達すると方向転換し、内周部流体移動
速度１３を持った内部循環流となる。As a result, a difference occurs between the displacement volume of the fluid due to the movement of the flat plate blade 3 and the moving volume of the fluid at the outer peripheral portion, and the difference causes the flow in the radial direction. Appears as a moving speed of 12. The flow inward in the radial direction changes its direction when reaching the central portion, and becomes an internal circulation flow having an inner peripheral fluid movement velocity 13.
このようにして発生した内部循環流は強大であり、内周
部流体移動速度１３は、回転軸２の表面の移動速度１４
や、傾斜翼４の内周部移動速度１５を大きく上廻る現象
が生じる。The internal circulation flow generated in this way is strong, and the inner peripheral fluid moving speed 13 is the moving speed 14 of the surface of the rotating shaft 2.
Alternatively, a phenomenon occurs in which the moving speed 15 of the inner peripheral portion of the inclined blade 4 is greatly exceeded.
一方、外周部流体移動速度１１は、傾斜翼４の外周部移
動速度１６を大きく下廻っている。On the other hand, the outer peripheral fluid movement speed 11 is far below the outer peripheral movement speed 16 of the inclined blade 4.
第４図は、第３図の外周部の流動状況をＡ−Ａ面から観
察したものである。傾斜翼３の移動速度１６に較べて、
外周部流体移動速度１１は小さいため、流体は矢印１７
で示すように下方に移動する。FIG. 4 is an observation of the flow condition of the outer peripheral portion of FIG. 3 from the AA plane. Compared to the moving speed 16 of the inclined wing 3,
Since the outer peripheral fluid movement speed 11 is small,
Move downward as indicated by.
第５図は、第３図の内周部の流動状況をＡ−Ａ面から観
察したものである。この部分では、第４図の外周部とは
逆に、傾斜翼３の移動速度１５に較べて、内周部流体移
動速度１３は大きくなるため、流体は矢印１８で示すよ
うに上方に移動する。FIG. 5 is an observation of the flow condition of the inner peripheral portion of FIG. 3 from the AA plane. In this portion, contrary to the outer peripheral portion of FIG. 4, the inner peripheral fluid moving speed 13 is higher than the moving speed 15 of the inclined blade 3, so that the fluid moves upward as shown by arrow 18. .
大形の平板翼３は上記のとおり、２種の流れ、特に内部
循環流を発生させる役割を持っているため、その寸法に
制限がある。第３図において、平板翼３の前方部では、
平板翼３が流体を排除して移動するため正圧状態であ
り、後方部では、平板翼３の移動で生じた空間を満たす
如く、内部循環流が流入するため負圧状態となる。この
ように、平板翼の前後部では圧力差が存在しているた
め、平板翼３の先端と容器内壁６との間隙を短絡する流
れが生じることとなる。As described above, the large-sized flat plate blade 3 has a role of generating two kinds of flows, especially an internal circulating flow, and therefore its size is limited. In FIG. 3, in the front part of the flat plate blade 3,
Since the flat plate blade 3 moves by removing the fluid, it is in a positive pressure state, and in the rear part, the internal circulation flow flows in so as to fill the space created by the movement of the flat plate blade 3, so that it is in a negative pressure state. Thus, since there is a pressure difference between the front and rear portions of the flat plate blade, a flow that short-circuits the gap between the tip of the flat plate blade 3 and the inner wall 6 of the container is generated.
短絡流の増大に比例して、内部循環流が減少するため、
短絡流を極力抑える必要がある。本発明者らの種々の実
験結果から、内部循環流を発生させるためには、回転軸
の軸芯５と容器壁６及び液面で囲まれた面積に対して、
軸芯５と平板翼３の外縁で囲まれた面積が６０パーセン
ト以上、好ましくは８０パーセント以上とする必要があ
ることを見出している。Since the internal circulation flow decreases in proportion to the increase in short circuit flow,
It is necessary to suppress the short circuit flow as much as possible. From the results of various experiments by the present inventors, in order to generate an internal circulation flow, with respect to the area surrounded by the axis 5 of the rotating shaft, the container wall 6 and the liquid surface,
It has been found that the area surrounded by the shaft core 5 and the outer edge of the flat plate blade 3 needs to be 60% or more, preferably 80% or more.
また、傾斜翼４の取付傾斜角については、自由に選定す
ることができる。第１図、第２図、第３図では外周部が
下方へ、内周部が上方へ移動する上下流が形成される
が、傾斜角を逆にすることにより逆方向の上下流が形成
される。Further, the mounting inclination angle of the inclined blade 4 can be freely selected. In FIGS. 1, 2, and 3, the outer peripheral portion moves downward and the inner peripheral portion moves upward, but the upstream and downstream are formed by reversing the inclination angle. It
