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。
以下、本発明の一実施例を図面に基づき説明する。
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。
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
）攪拌翼の取付け位置までの液圧によつて液体ｏ を撹

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。
（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。
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。
なお、例えば攪拌翼先端の傾斜面を回転に対して前面に
形成すれば気体吸い込みは生じｉ０ない。また、第３図
仮想線で示すように、攪拌槽４内にバッフル５を取シ付
けると、攪拌による液体の旋回流が減少するため、撹拌
翼先端の後面に生じる負圧の渦力が増し、撹拌翼による
気体の吸い込み性能は向上する。更に、第４図に示すよ
う■５ に、攪拌翼１を複数段に設ければ、気体吸い込
みを増すことができる。以上のように、本発明の気体白
