〔産業上の利用分野〕
本発明は例えば養魚場、或は食品製造工場、汚泥処理工
場、化学工場等に於て液中或は水中に空気或は酸素ガス
等を分散させたり、Ａ液中へＢ液体を分散させたりする
流体分散装置に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to the production of air or oxygen gas in liquid or water in, for example, fish farms, food manufacturing plants, sludge processing plants, chemical plants, etc. The present invention relates to a fluid dispersion device that disperses liquid B into liquid A.
以下の説明に関しては主として水中への気体の分散の場
合を例にとったが一般にＡ液中へＢ気体又はＣ液体を分
散する場合に適用できる。The following explanation mainly takes the case of dispersing gas into water as an example, but it can generally be applied to the case of dispersing B gas or C liquid into A liquid.
従来の流体分散装置は、多孔質のスボンヂ、或はセラミ
ック等を通して気体を水中或は液中に微粒子状にして分
散させるか或はベンチュリー管の吸気部より気体を供給
し、ポンプ等によりベンチュリー管に送水して気体を液
中に分散させた。Conventional fluid dispersion devices disperse gas in the form of fine particles in water or liquid through a porous sponge or ceramic, or supply gas from the intake part of a Venturi tube, and then insert the gas into the Venturi tube using a pump or the like. water was supplied to disperse the gas in the liquid.
或は又養魚場等に於ては水面に水車を浮かせて回転させ
水をすくって空中に散布させるものがあったがこれは水
面近くの効果だけであった。Alternatively, at fish farms, etc., there were water wheels that were floated on the surface of the water and rotated to scoop up water and scatter it into the air, but this only had an effect near the surface of the water.
液中、或は又水中の深い処まで空気その他の気体を分散
させるのに簡単な方法でしかもごみ詰り等の故障を生じ
ない方法を求めること。To find a simple method for dispersing air or other gas deep into liquid or water, and which does not cause failures such as clogging with dirt.
液中でプロペラを高速回転させると、プロペラはその回
転軸線上でかなりの後方まで液を送ることが出来、養魚
池等では底の方まで水を送ることが出来る。When a propeller is rotated at high speed in liquid, it can send liquid quite far back on its axis of rotation, and can send water all the way to the bottom of fishponds and the like.
プロペラの回転軸を中空にして、一端を空中に保ち他端

ペラ後部の流れのために水中に微小な気泡となって吸込
まれ、流れと共にかなりの距離にまで達する。しかも、
ロープ等がプロペラにからまない限り多少の異物は流れ
去ってゆき配管の場合のベンチュリ一部の目詰りの様な
故障は生じない。If the rotating shaft of the propeller is made hollow, with one end in the air and the other end opened at the rear of the propeller position, air will be sucked into the water in the form of minute bubbles due to the flow behind the propeller, and as the flow moves, the air will be drawn into the water considerably. reach a distance of Moreover,
As long as the rope does not become entangled with the propeller, some foreign matter will flow away and no malfunctions will occur, such as clogging of a part of the venturi in the case of piping.
プロペラの後部の流れの中に水上からパイプをさしこん
で水中の開口部をプロペラが起す流れのほぼ中心軸上に
もっていっても今様に空気は微粒となり水中に分散して
送りこまれる。Even if a pipe is inserted from above the water into the flow behind the propeller and the opening in the water is placed almost on the central axis of the flow generated by the propeller, the air will become fine particles and be dispersed into the water.

、この開口部が少なくとも流れの下流にむく限り開口部
附近の管内は減圧状態となって、外気を吸引する。これ
は丁度ベンチュリー管と内外の関係が逆位置になった様
な状態である。At the rear of the propeller, near the rotating shaft, the pressure decreases due to the flow velocity, so if the opening of the vent pipe from above the water or liquid is placed here, the gas will pass through this pipe and enter the liquid. It is sucked into the water, becomes fine particles, and flows with the rotation of the flow. In general, in a Venturi tube, if a small cross-sectional area is provided in the pipe, the flow velocity will increase in this part, and if there is an opening in this narrowed part, the pressure here will decrease and the external fluid will be sucked in, but the propeller In the case of , there is a long and narrow high-speed flow induced by a propeller in a wide liquid at rest, and if an opening for gas outside the liquid is located near the axis of this high-speed flow, this opening will at least As far as the downstream side goes, the inside of the pipe near the opening is in a reduced pressure state and outside air is sucked in. This is just like the Venturi tube and the relationship between the inside and outside being reversed.

まで微細な気泡と共に到達する。In a Venturi, if foreign matter flows into the narrow part of the liquid flow path, it may become clogged and no longer function properly.In addition, in a water wheel that splashes water on the water surface, the air bubbles generated close to the water surface. However, according to the method of the present invention, there is no phenomenon such as clogging unless a long rope is wound in, and the water flow induced by the propeller can be carried far underwater with minute air bubbles. reach.
