ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for stirring and mixing liquid and gas, and more specifically, its purpose is to more efficiently dissolve gas into liquid.

溶け込むのに充分な時間を得ることができなかつ
た。 As a device for dissolving gas such as air into liquid such as water, a compressor or blower is used to forcefully feed air into a pipe placed underwater.
This pipe has many small holes that eject air into the water as bubbles, or a water wheel is rotated by a motor or other drive device at the water surface to generate intense water spray, which causes many bubbles to flow into the water. However, the bubbles produced by these devices are so large that they rise to the surface of the water in a short period of time due to the buoyancy of the bubbles themselves, causing the air to dissolve into the water. I couldn't get enough time for it.
この上記した液体と気体との撹拌混合装置は、
養殖、浄水等の多方面において使用されているの
であるが、気体を液体内により大量に溶け込ませ

ている。 The above-mentioned stirring and mixing device for liquid and gas is
Although it is used in many fields such as aquaculture and water purification, there is a strong desire for a stirring and mixing device that can dissolve a larger amount of gas into a liquid.

合の悪い事態になることがしばしば生じている。 In particular, when there is little water coming in and out of the aquaculture pond, such as in the case of eel farming, the agitation and mixing device described above has little air dissolution into the water, so the agitation and mixing device is driven continuously. However, in a short period of time, not only does the concentration of ammonia in the water increase, but also blue-green algae appear, which is often extremely inconvenient for aquaculture.

せることができるようにしたものである。 The present invention was devised to eliminate the drawbacks, problems, and dissatisfaction of the conventional examples described above and to meet the demands. Extremely small bubbles in a liquid have their own buoyancy due to a phenomenon similar to Brownian motion. By focusing on the fact that it is possible to stay in a floating position irregularly in a liquid for a long period of time, it is possible to generate extremely small bubbles by the intense swirling motion of the liquid.

8000〔rpm〕以上という極めて高速で回転される
ため、水との間の摩擦をできる限り少なくするた
めである。 The outer peripheral surface of the driving body 1, which is the main part of the device of the present invention, is polished to an extremely smooth surface.
This is to minimize friction with the water as it rotates at extremely high speeds of over 8000 rpm.
この駆動体１の外周面が平滑でないと、高速回
転している駆動体１に激しい振動が発生してしま

しまう。 If the outer peripheral surface of the drive body 1 is not smooth, severe vibrations will occur in the drive body 1 rotating at high speed, making it impossible to obtain the desired rotation speed.
駆動体１の外径、間隙５の値、外殻体２の長さ
すなわち水中に位置する駆動体１の長さ等は、駆
動される駆動体１の回転速度、使用されるモータ
８等の駆動源の馬力、さらには要求される単位時
間における撹拌力等により選択設定される。 The outer diameter of the driving body 1, the value of the gap 5, the length of the outer shell 2, that is, the length of the driving body 1 located underwater, etc. are determined by the rotational speed of the driving body 1 to be driven, the motor 8 used, etc. It is selected and set depending on the horsepower of the driving source, the required stirring force per unit time, etc.
例えば、駆動体１の直径を27φに設定した場

〔mm〕）であり、間隙５は３〜６〔mm〕が最適であ
つた。 For example, when the diameter of the driver 1 is set to 27φ, the length of the outer shell 2 is 1300 [mm] (approximately 1200 mm underwater).
[mm]), and the optimum gap 5 was 3 to 6 [mm].

開口４から10万分の１〔cm〕程度の多量の気泡が
水中に噴出され、その気泡は、その大きさが極め
て小さいので長時間の間、水中に遊動位置する。 Under the above dimensional conditions, drive body 1 at 8000 [rpm]
When rotated at ~9000 [rpm], a large amount of air bubbles about 1/100,000 [cm] in size are ejected from the lower end opening 4 of the outer shell 2 into the water, and because the size of the air bubbles is extremely small, it lasts for a long time. During this time, it is floating in the water.
上記した水中に噴出された気泡は、そのままで

強い光を照射することにより、あたかも空気中の
煙の如く、白く輝いた粒子状に視覚することがで
きる。 The bubbles ejected into the water mentioned above are not visible to the human eye as they are, but by irradiating them with strong linear light, they become white particles that shine like smoke in the air. Can be visualized.
ところで、本発明者の実験によれば、前記寸法

殻体２の長さを大きくすると過負荷状態となつて
所望の回転速度が得られないという結果を得た。 By the way, according to the inventor's experiments, among the above-mentioned dimensional relationships, when the length of the outer shell 2 is shortened, the diameter of the generated bubbles tends to increase; It was found that if the rotation speed was increased, an overload condition occurred and the desired rotation speed could not be obtained.
また、間隙４の値を10〔mm〕程度に大きくする
と、発生する気泡の径が大くなる傾向が現われ、
反対に３〔mm〕以下にすると、間隙４内に水が侵
入し難くなつて充分な量の気泡を得ることができ
なかつた。 Furthermore, when the value of gap 4 is increased to about 10 [mm], the diameter of the generated bubbles tends to increase,
On the other hand, if it is less than 3 mm, it becomes difficult for water to enter the gap 4, making it impossible to obtain a sufficient amount of bubbles.
このように、駆動体１の径、間隙４の値、外殻

寸法関係は、駆動体１の回転速度に従つて設定さ

A large amount of air bubbles with an extremely small diameter of 1/10,000 cm are released into the water, and as mentioned above, the air bubbles released into the water according to the present invention are extremely small in diameter. Due to its own buoyancy, it does not rise to the surface of the water in a short period of time, but remains in the water for a long time, moving erratically, making it less effective at absorbing oxygen and nitrogen from the air. can be dissolved in water.
ところで、本発明装置により得られる気泡は、

る。 By the way, the bubbles obtained by the device of the present invention are
The water in the gap 5 becomes a violent vortex due to the high-speed rotation of the driving body 1, and as this is generated, water is jetted downward from the lower end opening 4 of the outer shell 2 along the vortex. As a result, the direction of ejection is restricted, making it difficult to disperse over a wide area underwater in a short period of time.

A ventilation passage 14 is formed at both the upper and lower end surfaces of the drive body 1, and a number of air discharge holes 16, which are small holes, are formed in the peripheral wall at the lower end of the drive body 1 protruding from the lower end opening 4 of the outer shell 2. It is preferable to attach and fix the short cylindrical bottom body 15 coaxially with its internal space communicating with the ventilation passage 14 .

噴出気泡により、下端開口部４の直下の水中に
は、放射方向への水流が形成されることになる。 In the case of the embodiment shown in FIGS. 2 and 3, when the driver 1 is driven to rotate at high speed, a large amount of water is released from the lower end opening 4 of the outer shell 2 due to the action of the driver 1 and the outer shell 2. Fine bubbles are ejected in exactly the same way as in the embodiment shown in FIG. Due to the ejected bubbles, a radial water flow is formed in the water immediately below the lower end opening 4.
それゆえ、外殻体２の下端開口部４から下方に
向つて噴出された多量の極めて細かい気泡は、上
記した放射方向の水流にのつて四方に分散される
ことになる。 Therefore, a large amount of extremely fine air bubbles ejected downward from the lower end opening 4 of the outer shell 2 are dispersed in all directions along with the above-mentioned radial water flow.
