Description
【発明の詳細な説明】
本発明は気体画成式撹拌翼に関するもので、その目的と
するところは、気液攪拌槽内の液体に外部からの強制的
手段を使用せずに気体を混入させることにある。[Detailed Description of the Invention] The present invention relates to a gas-defined stirring blade, and its purpose is to mix gas into the liquid in a gas-liquid stirring tank without using any external forced means. There is a particular thing.
以下、本発明の一実施例を図面に基づき説明する。Hereinafter, one embodiment of the present invention will be described based on the drawings.
第１図及び第２図において、１は本発明に係る攪拌翼で
、中空回転軸２の先端に、且つ該中空回転軸２に対して
垂直面内で複数個（本実施例では４個）互いに等間隔で
取付けられている。In FIGS. 1 and 2, reference numeral 1 denotes stirring blades according to the present invention, and a plurality of stirring blades (four in this embodiment) are installed at the tip of a hollow rotating shaft 2 and in a plane perpendicular to the hollow rotating shaft 2. They are mounted at equal intervals from each other.
そして、上記撹拌翼１先端の回転方向Ａに対して後面が
４５０に傾斜１ａさせられ、且つ該傾斜面１ａには前記
中空回転軸２の中空部２ａに連通する開口３が有せしめ
られている。即ち、攪拌翼１はパイプの先端を４５０で
切り落としたものである。従つて、第３図に示すように
、上記攪拌翼１を攪拌槽４内の液体中で矢印Ｂ方向に回
転させれば、攪拌翼１の先端後側の傾斜面１ａに設けら
れた開口３から気体が自然に液体中に吸出されていく。
ここで、気体が自然に吸出される理由を考察す、 る。
撹拌翼が液体中で回転しているとき、中空回転軸の上端
より吸込まれた気体の出口である攪拌翼先端には、下記
のような３種類の力が作用していると考えられる。（ａ

液体に働く遠心力によシ液体が攪拌翼外に飛び出そうと
する力。The rear surface is inclined 1a at 450 with respect to the rotational direction A of the tip of the stirring blade 1, and the inclined surface 1a is provided with an opening 3 communicating with the hollow portion 2a of the hollow rotating shaft 2. . That is, the stirring blade 1 is a pipe whose tip is cut off at 450 mm. Therefore, as shown in FIG. 3, when the stirring blade 1 is rotated in the direction of arrow B in the liquid in the stirring tank 4, the opening 3 provided in the inclined surface 1a on the rear side of the tip of the stirring blade 1 opens. The gas is naturally sucked out into the liquid.
Let's now consider why gas is naturally sucked out.
When the stirring blade is rotating in a liquid, the following three types of forces are considered to be acting on the tip of the stirring blade, which is the outlet of the gas sucked in from the upper end of the hollow rotating shaft. (a
) A car tries to force the liquid o into the stirring blade by the hydraulic pressure up to the stirring blade installation position. (b) The liquid flows out of the stirring blade due to the centrifugal force acting on the liquid inside the stirring blade during rotation. The power to do so.
（ｃ）攪拌翼の後面に生じた負圧の渦によつて攪拌翼内
の液体を吸い出そうとする力。(c) A force that tries to suck out the liquid inside the stirring blade by a negative pressure vortex generated on the rear surface of the stirring blade.
５ 従つて、上記（ａ）項で述べた液圧による力よυも
、０））及び（ｃ）項で述べた遠心力及び渦力による力
の方が大きいため、攪拌による気体吸い込みを可能にし
ている。5 Therefore, the force due to the liquid pressure mentioned in item (a) above is larger than the force due to the centrifugal force and the vortex force mentioned in item 0)) and (c), so it is possible to suck in gas by stirring. I have to.

服式攪拌翼によれば、気液撹拌槽内の液体中に強制的手
段を使用せずに気体を混入させることができる。Note that, for example, if the inclined surface of the tip of the stirring blade is formed in front with respect to rotation, gas suction will not occur i0. In addition, as shown by the imaginary line in Figure 3, when a baffle 5 is installed in the stirring tank 4, the swirling flow of the liquid due to stirring is reduced, so the vortex force of the negative pressure generated on the rear surface of the stirring blade tip increases. , the gas suction performance of the stirring blade is improved. Furthermore, as shown in FIG. 4 (5), if the stirring blades 1 are provided in multiple stages, gas suction can be increased. As described above, according to the gas white-coat type stirring blade of the present invention, gas can be mixed into the liquid in the gas-liquid stirring tank without using any forced means.
