【発明の詳細な説明】
本発明は液体に気体を混合させて微粒気泡を発
生させる曝気装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aeration device that mixes gas with a liquid to generate fine bubbles.
従来、此種装置としては水中ポンプで液体を噴

め、実質的に２ｍ未満の浅い液中でしか使用でき
ず、その用途は極めて限られる欠点があつた。 Conventionally, this type of device uses a submersible pump to eject liquid and forcefully inserts gas sent through a vent hole to generate microscopic bubbles in the liquid. Because it requires power, it can only be used in shallow liquids of less than 2 m, which has the drawback that its applications are extremely limited.

生利用ができない欠点がある。 The first device that eliminates the above-mentioned drawbacks of conventional devices
As shown in the figure, a radial partition plate is attached to the lower part of the ventilation pipe A, and the liquid taken in from the liquid intake port C is radiated into the liquid tank. A suction device has been proposed (see Utility Model Publication No. 52-6955). However, although this device certainly functions effectively even in liquids at a depth of 2 meters or more, it is not suitable for large-scale aeration, and both the liquid and gas outlets are narrow and have a complicated configuration, so it does not remove lint. It is easy to get clogged with other debris, which puts an overload on the drive motor and shortens the life of the motor.Furthermore, once debris becomes entangled, it is difficult to remove and cannot be recycled.
本発明者は此等従来曝気装置の欠点を解消し、
汎用性が高くしかも取扱いの簡便な装置を得んと

させるに至つた。 The present inventor has solved the drawbacks of these conventional aeration devices,
As a result of intensive research in an effort to obtain a device that is highly versatile and easy to handle, the inventors came up with the idea of utilizing the negative pressure generated by overflow of liquid, and thus completed the present invention.

層能率的にすることができる。 The impeller 2 has any width, length, and thickness, and is fixed to the lower side 1a of the drive shaft 1 by appropriate means. Stable results are obtained when 4 to 8 sheets are attached radially.
In addition, when using a plurality of impellers 2, their upper end portions 2a, 2a... and lower end portions 2b, 2b
It is advisable to arrange reinforcing plates 2c and 2d on either or both of.... In this case, in particular, a reinforcing plate 2c is attached to the upper end 2a, and preferably to the lower end 2b.
An appropriate number of holes 2e of an appropriate size are bored in a portion of the reinforcing plate 2d to be attached to the reinforcing plate 2d other than the portion where the impeller 2 contacts. Thus, when the device of the present invention is used, gas flows down from the holes 2e of the reinforcing plate 2c, and the reinforcing plate 2
Liquid flows in through the hole 2e of d, making it possible to mix gas and liquid more efficiently.

のがよい。 The outer pipe 3 is fixed by suitable support means (not shown) so that gas flows into the space between it and the drive shaft 1 from above, and has a function of supplying gas to the impeller section. There is. It is preferable that the lower end 3b of the outer pipe 3 is formed into a flange shape having a width equal to or greater than the width of the impeller 2. In this way, gas can be more smoothly supplied to the impeller section. As described above, the upper end 2a of the impeller 2 is configured to maintain an appropriate gap between it and the lower end 3b of the outer pipe 3. This is to ensure smooth rotation of the impeller 2, but the size of this gap is preferably 10 mm or less, which is enough to suck in gas by effectively utilizing the negative pressure generated on the back surface when the impeller rotates. It is preferable to set it to 2 to 3 mm or less.

る。 The device of the present invention is used by being connected to a rotating mechanism as described above. The drive shaft 1 is rotated by the operation of the rotation mechanism, which causes the impeller 2 to rotate in the liquid and generate a vortex, and negative pressure is generated in the liquid on the back side of the impeller 2 in the rotating direction, causing the drive shaft 1 and the outer pipe to rotate. The gas that has passed through the space between 3 and 3 is mixed into the vortex. The mixed gas generates extremely fine bubbles in the liquid due to the vortex and the shearing force of the impeller 2.

で処理するのに広く用いることができる。 The device of the present invention converts liquid into gas (air, oxygen, etc.) in septic tanks, sewage treatment tanks, fish culture tanks, plant cultivation tanks, etc.
It can be widely used for processing.
本発明の装置は下記のような技術的効果を有し
ている。 The device of the present invention has the following technical effects.
(1) 気体を液中に導入するのは自吸式であり多量
の気体を極微粒気泡として 液中に発生させる
ことができる。(1) Gas is introduced into the liquid by a self-priming method, and a large amount of gas can be generated in the liquid as microscopic bubbles.
(2) インペラーの回転方向の背面に発生する負圧
を応用する構造のため、液中に強力な真空圧を
発生させ、小さなエネルギーで気体を液中の吸
引させることができる。而して水深が２ｍ以上
の所でも容易に目的を達することができる。(2) The structure uses the negative pressure generated on the back side of the impeller in the rotating direction, so it can generate strong vacuum pressure in the liquid and suck gas into the liquid with a small amount of energy. Therefore, you can easily reach your goal even in places where the water depth is 2 meters or more.
(3) 一度に多量の気体を噴出させることができる
ので強力な上昇流を発生し、周囲の液体に対流
現象を起させ、水槽全体に均一に空気を供給で
きる。(3) Since a large amount of gas can be ejected at once, a strong upward flow is generated, causing a convection phenomenon in the surrounding liquid, and air can be uniformly supplied throughout the aquarium.
(4) 気体を極微粒化して液体中に混入するため、
例えば醸素の液解効率を高める事ができる。(4) In order to make the gas into ultra-fine particles and mix it into the liquid,
For example, it is possible to increase the efficiency of fermentation.
(5) 従来の曝気装置におけるような液体に流動エ
ネルギーを発生させる構造でないため、使用エ
ネルギーを大幅に節約できる。(5) Since it does not have a structure that generates flow energy in the liquid like in conventional aeration equipment, it can significantly save energy.

ある。(6) Since the device does not have a structure in which liquid flows into the device and is injected, there is no clogging with debris, which prevents overload of the drive motor and extends the life of the motor. Furthermore, even if waste becomes entangled in the device, it can be removed immediately, allowing for long-term reuse.
(7) 極めて簡単な構造であり、容易に分解組立て
