明による特公昭６１−３６４４８号公報がある。2. Description of the Related Art As a gas-liquid stirring and mixing apparatus for efficiently dissolving a gas such as air in a liquid such as water, there is Japanese Patent Publication No. 61-36448 invented by the present inventor.
【０００３】この特公昭６１−３６４４８号公報に示さ

間隙内に侵入することができる範囲で、できる限り小さ
い値に設定した構成となっている。In the prior art disclosed in Japanese Patent Publication No. 61-36448, an upper end opening portion which is opened in a gas atmosphere to be stirred and mixed is arranged so as to project above the liquid surface of the liquid to be stirred and mixed. It consists of a linear cylindrical outer shell and a linear cylindrical driver that is coaxially inserted and assembled over the entire length of the outer shell, and is driven to rotate at high speed. The gap is set to a value as small as possible within the range in which the liquid can enter the gap when the drive body rotates at high speed.
【０００４】上記構成の従来技術は、液体に比べてはる
かに比重の小さい気体であっても、極めて小さい気泡状
となって液体中に存在する場合には、ブラウン運動に似

運動させることにより液体中に気体の極めて小さい気泡
を発生させ、この極めて小さいかつ多数の気泡を液体中
に長時間位置させることにより、気体の液体への溶け込
みを、極めて効率良く達成するものとなっている。In the prior art having the above-mentioned structure, even if the gas has a much smaller specific gravity than that of the liquid, when it is present in the liquid in the form of extremely small bubbles, the bubbles are caused by a phenomenon similar to Brownian motion. Focusing on the fact that the buoyancy acting on the air can be overcome and the robot can be positioned while floating randomly in the liquid for a long time, and by vigorously swirling the liquid in the gas atmosphere, By generating extremely small bubbles and arranging these extremely small and large numbers of bubbles in the liquid for a long time, the dissolution of gas into the liquid is achieved very efficiently.

出により極めて細かいそして多数の気泡を液体中に長時
間にわたって遊動させるのである。That is, liquid and gas are introduced into the gap between the outer shell and the driver, and the liquid is stirred and mixed with the gas by vigorous swirling motion of the liquid generated by the high-speed rotational motion of the driver. The generated liquid containing a large number of fine bubbles is vigorously discharged from the lower end opening of the outer shell, and this discharge causes the extremely fine and large number of bubbles to float in the liquid for a long time.
【０００６】[0006]
【発明が解決しようとする課題】しかしながら、上記し

程度の高速で回転駆動させる必要があると云う問題があ
った。However, the above-mentioned prior art can certainly discharge a large number of extremely fine bubbles into a liquid, but in order to generate gas into sufficiently fine bubbles, It is necessary to give the liquid in the gap between the outer shell and the driving body a sufficiently strong vortex motion, and in order to obtain bubbles of a desired size by this vortex motion, the peripheral speed of the outer peripheral surface of the driver is Since a high speed of about 12 m / sec is required, drive the drive at about 7,000 rpm.
There was a problem that it was necessary to drive the rotation at a high speed.
【０００７】また、このように高速回転駆動される駆動

あることから、一定以上の長さを持たなければならず、
このためこの高速回転駆動される駆動体自体および駆動
体を回転可能に支持する部分には、高速回転する駆動体
に振動等が発生しないように、極めて高い機械成形寸法
精度で製造される必要があると云う問題があった。Further, since the driving body driven to rotate at a high speed as described above needs to stir and mix the liquid and the gas for a certain period of time or more, it must have a certain length or more,
For this reason, it is necessary that the driving body itself that is driven to rotate at high speed and the portion that rotatably supports the driving body be manufactured with extremely high mechanical molding dimensional accuracy so that vibration or the like does not occur in the driving body that rotates at high speed. There was a problem to say.

高速回転駆動される駆動体の重量が大きくなって、駆動
体の軸受け部分に早期磨耗が生じるとか、駆動体の回転
駆動源として出力容量の大きいものを必要とすると云う
問題があった。As described above, since the peripheral speed of the outer peripheral surface of the driving body is required to be high, it is necessary that the diameter of the driving body itself be larger than a certain size. There has been a problem that the weight of the driven body becomes large, and the bearing portion of the driven body is prematurely worn, or a rotary drive source for the driving body requires a large output capacity.

発揮する勢いだけで放出されるので、その放出勢いが必
ずしも充分ではなく、このため多数の細かい気泡の到達
範囲が満足できる大きさにならないと云う問題があっ
た。Further, since many fine bubbles released into the liquid are released only by the force exerted by the vortex flow generated in the gap between the outer shell and the driver, the force of release is not always sufficient. Therefore, there is a problem in that the reach of a large number of fine bubbles does not reach a satisfactory size.

ずしも効率良く達成されず、比較的多量のオゾンが大気
中に無駄に放散すると云う問題があった。Furthermore, since it is effective to mix ozone that exerts a high sterilizing action and a high purifying action into the gas that is stirred and mixed with the liquid, the ozone generated by the ozone generator is used as an outer shell. It is guided near the upper opening of the body and is made to be sucked into the outer shell together with other gas by the suction force exerted by the vortex motion in the outer shell, but it is disturbed by the flow of other gas. However, there is a problem in that the suction of ozone into the outer shell is not always achieved efficiently, and a relatively large amount of ozone is wastefully emitted into the atmosphere.

的とする。Therefore, the present invention was devised to solve the above-mentioned problems in the prior art. It reduces the weight of the rotating body that stirs and mixes liquid and gas by rotating operation, and also provides relatively low rotation. The technical issue is to generate sufficiently fine bubbles at a high speed and to increase the ozone content in the bubbles. Therefore, it is easy to manufacture, exhibits stable operation for a long time, and has a small output capacity. The purpose is to obtain sufficiently fine bubbles with a driving source and to obtain bubbles having a strong sterilizing and purifying ability.

Having a plurality of stirring blades fixed at intervals along the axial direction, fixed to the base end located immediately above the water surface of the rotary shaft, and by rotating this rotary shaft, the gas is directed into the outer cylinder. Having an air supply blade for supplying air, having a base end connected to an ozone generator, and having an inlet pipe with the tip open near the air supply blade, a rotating shaft protruding from the tip end opening of the outer cylinder

である。The rotating shaft and the outer cylinder are assembled in a hanging shape, and the base plate on which the drive member for rotatably driving the rotating shaft and the ozone generator are mounted and fixed is placed horizontally on the water surface. It is advantageous to attach a float to raise the surface.
【００１４】[0014]
【００１５】攪拌羽根の羽根径を、外筒の内径よりもわ

【００１７】回転軸の先端を回転自在に支持する軸受け

転軸を設定された回転速度で回転駆動すると、外筒内の
液体に渦流運動が発生すると共に、外筒の基端部開口か
ら気体が外筒内に吸引されて液体と攪拌混合される。Before the rotational drive of the rotary shaft, the outer cylinder is substantially filled with the liquid. When the rotary shaft is driven to rotate at the set rotational speed from this state, a swirling motion is generated in the liquid in the outer cylinder, and the gas is sucked into the outer cylinder from the base end opening of the outer cylinder and stirred with the liquid. Mixed.
【００２０】すなわち、回転軸が回転すると、この回転
軸と外筒との間の液体は、回転軸を中心とした渦流を形
成すると共に、この液体の渦流の吸い込み作用により気
体を回転軸に沿って吸い込むのである。That is, when the rotary shaft rotates, the liquid between the rotary shaft and the outer cylinder forms a vortex flow centering on the rotary shaft, and the suction action of the vortex flow of the liquid causes the gas to flow along the rotary shaft. And inhale.
【００２１】このようにして、液体と一緒になって吸い
込まれた気体は、液体の渦流運動により攪拌混合される

液体と激しく攪拌混合される。In this way, the gas sucked together with the liquid is agitated and mixed by the vortex motion of the liquid, and at the same time, by the agitating blade rotating integrally with the rotating shaft,
Stir and mix with liquid vigorously.

なるので、効果的に達成されることになる。The stirring and mixing operation of the liquid and gas by the stirring blade is performed by vigorous cutting operation of the mixture of liquid and gas by each blade piece of the stirring blade and the forward blade of the stirring blade for the mixture of liquid and gas. Kneading due to collision between the given forward movement (direction toward the tip end opening of the outer cylinder) and the opposite movement (direction toward the base end opening of the outer cylinder) given by the reverse blade of the stirring blade And the stirring and mixing action is achieved by the pushing back action on the mixture of liquid and gas by the reverse blade.
This mixture is retained effectively in the outer cylinder for a relatively long time, which is effectively achieved.

ことになる。The mixture of the liquid and the gas in the outer cylinder moves in the forward direction in the outer cylinder mainly due to the swirling motion associated with the rotating motion of the rotary shaft, and is discharged from the tip opening as it is. The momentum of the release of the mixture of gas and gas from the tip opening is
It is not determined only by the vortex motion associated with the rotating motion of the rotating shaft, but is also related to the strength of the pushing force exerted by the forward blade and the pushing back force exerted by the reverse blade in the stirring blade, and the pushing force exerted by the forward blade Is stronger than the pushing-back force exerted by the counter blade, the above-mentioned force of discharge of the mixture from the tip opening becomes strong, and a large number of fine bubbles in the mixture are diffused to a wider extent by the amount of the strong discharge force. It will be.

おける滞留時間が短くなり、すなわち混練時間が短くな
り、気泡の細分化程度が不充分となる場合がある。However, when the pushing force of the forward blade is set to be stronger than the pushing back force of the reverse blade, it means that the moving speed of the mixture of liquid and gas in the outer cylinder in the forward direction is fast. Therefore, the residence time of the mixture in the outer cylinder is shortened, that is, the kneading time is shortened, and the degree of subdivision of air bubbles may be insufficient.

されることになる。Therefore, when it is desired to sufficiently achieve the subdivision of the bubbles and to diffuse the sufficiently subdivided bubbles in a wider range, a diffuser is provided at the tip of the rotary shaft. This diffusion device rotates integrally with the rotating shaft and utilizes this rotating operation to expel the liquid in a radial direction with vigor, so that the ejection force of the mixture of the liquid and gas ejected from the opening of the tip of the outer cylinder is expelled. Even if the strength is not strong, this mixture will be diffused extensively on the liquid stream that is vigorously discharged by the diffusion device.

率良く外筒内に吸い込まれる。The air supply blade attached to the base end of the rotary shaft supplies the gas in the vicinity into the outer cylinder as the rotary shaft rotates, and is introduced near the air supply blade. Since the tip of the tube is open and the ozone generated by the ozone generator is discharged to the vicinity of this air blower blade, the ozone supplied from the ozone generator is forced by this air blower blade toward the inside of the outer cylinder. Will be sucked into the outer cylinder smoothly and efficiently.

This eliminates the need for a structure for mounting and fixing, which simplifies the installation of the stirring and mixing device in a pond or the like and facilitates its movement.

長さが大きい程、気泡の細分化の力は大きい。In the illustrated embodiment, the stirring blade 8 is constituted by a combination of one forward blade 8a and one reverse blade 8b, and the forward blade 8a is a base end of the rotary shaft 4 with respect to the reverse blade 8b. The number of the stirring blades 8 arranged on the side depends on the required degree of mixing of liquid and gas, that is, the degree of subdivision of bubbles, the rotation speed of the rotating shaft 4, the length of the blade pieces of the stirring blade 8, and the like. The larger the number of stirring blades 8, the higher the rotation speed of the rotating shaft 4, and the longer the blade pieces, the larger the force of fragmentation of the bubbles.

る。When the rotary shaft 4 rotates, water near the base end opening 6 becomes a vortex and is drawn into the outer cylinder 5 together with air. Both the forward blade 8a and the reverse blade 8b of the stirring blade 8 promote the formation of a vortex by the rotating operation thereof and also promote the stirring of the mixture of water and air to promote the subdivision of bubbles. The rotating action of 8a promotes the pulling force of the vortex flow to push the mixture of water and air, and the rotating action of the reverse blade 8b weakens the pulling force of the vortex flow, and the mixture of water and air. To push back.

The mixing ability is increased, and this reverse flow also
The residence time of the mixture of water and air in the outer cylinder 5 is prolonged and the subdivision of generated bubbles is promoted.
