【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
生させる気液混合装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas-liquid mixing device that mixes gas with a liquid to generate fine bubbles.
従来、気液混合装置としては水中ポンプで液体
を噴出せしめ、通気孔から送られた気体を強制的
に差込ませて液体中に微粒気泡を発生させる装置
があるが、水深の深い所では膨大な動力を要する
ため、実質的に２ｍ未満の水深の浅い液中でしか
使用できず、その用途は極めて限られる欠点があ
つた。 Conventionally, gas-liquid mixing devices use submersible pumps to eject liquid, and gas sent through vents is forced into the liquid to generate microbubbles in the liquid. Since it requires a large amount of power, it can only be used in shallow liquids of less than 2 meters in depth, and has the disadvantage that its applications are extremely limited.
前記欠点を解消する装置も提案されているが
（例えば実公昭52−6955号等）、水深２ｍ以上の液
中で有効に機能するものは、大規模な曝気には適
さず、しかも液体排出口および気体排出口ともに
幅狭く、複雑な構成になつているため、糸屑その
他の屑物による目詰りが起り易く、このため駆動
モーターに過負荷がかかり、モーター寿命を縮め
てしまい、しかも一旦屑物がからまると除去する
のが困難で、再生利用ができない欠点があつた。 Devices that solve the above drawbacks have been proposed (for example, Utility Model Publication No. 52-6955, etc.), but devices that function effectively in liquid at a depth of 2 m or more are not suitable for large-scale aeration, and they do not have a liquid outlet. Since both the air outlet and gas outlet are narrow and have a complicated configuration, they are easily clogged with lint and other debris, which overloads the drive motor and shortens the life of the motor. Once things get tangled, they are difficult to remove and cannot be recycled.
更に第１図に示すように、パイプ先端部に螺旋
状のスクリユーＢを取付け、このスクリユーの回
転に伴なう水流によつてパイプからの空気を吹込
む装置が提案されている。 Furthermore, as shown in FIG. 1, a device has been proposed in which a spiral screw B is attached to the tip of a pipe, and air is blown from the pipe by a water flow caused by the rotation of the screw.
しかしこの装置では気体を極微粒子状態で吹込
めないこと、水流の方向がパイプに沿つた下方向
に限られること、また装置の設定はせいぜい水中
に対して斜方向にしか行うことができず、垂直方
向に設置できないこと等、その用途は極めて限ら
れる他、エネルギー消費も大きいという欠点があ
つた。 However, with this device, gas cannot be injected in the form of extremely fine particles, the direction of water flow is limited to the downward direction along the pipe, and the device can only be set at an angle to the water. Its uses are extremely limited, such as the inability to install it vertically, and it also has the disadvantage of high energy consumption.
本発明者はこれら従来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し

置を提案している（特願昭58−32890号、同58−
76256号、同58−76257号）。 The inventor of the present invention sought to eliminate the drawbacks of these conventional devices and create a device that is highly versatile and easy to handle, and as a result of intensive research, he came up with the idea of utilizing the negative pressure generated by overflow of liquid. has already proposed several types of devices (Patent Application No. 58-32890, No. 58-32890).
No. 76256, No. 58-76257).
本発明者は更に検討を重ねた結果、一層効率的
に気液を混合できる装置を完成させるに至つた。 As a result of further studies, the present inventor has completed an apparatus that can mix gas and liquid even more efficiently.
以下実施例を示す第２〜第５図により本発明内
容を説明する。 The content of the present invention will be explained below with reference to FIGS. 2 to 5 showing examples.

置である。 The present invention comprises a ventilation pipe having a gas intake port 1a above and an impeller 2 spirally attached around the ventilation pipe 1. A plurality of gas ejection holes 3, 3, 3... are bored spirally and/or on the back surface 2a in the rotational direction of the impeller 2, and if necessary, a blind plate 4 is provided at the lower end opening of the ventilation pipe 1. This is a gas-liquid mixing device equipped with

うにしてもよい（第３図参照）。 In the device of the present invention, the shape, diameter, and length of the ventilation pipe 1 are arbitrary, and may be determined as necessary. This ventilation pipe 1 is connected to a rotation mechanism so as to be rotatable. Also, this ventilation pipe 1
The diameter of the gas intake port 1a provided in the gas intake port 1a is not particularly limited, as long as it has a sufficient area for ventilation.
The number is arbitrary. This gas intake port 1a may be provided above the ventilation pipe 1, for example,
The upper end opening may be used as is, or if the upper end of the ventilation pipe 1 is used for connection with a rotating mechanism, it may be provided on the upper side 1b of the pipe 1 (see Figure 3). ).

る。 The impeller 2 installed in a spiral manner may be a plate-shaped one or a hollow type (see FIG. 2) attached to the pipe 1 so that the internal gap communicates with the gap of the ventilation pipe 1. good. The number of impeller threads and pitches is not limited to those shown in Figure 2 (1 thread, 1 pitch) and Fig. 3 (1 thread, 2 pitches), but multiple parallel impellers are installed, and the fumes are appropriately placed on the back of each impeller. Holes can be provided.
このインペラー２は全体が必ずしも連続するよ
うなものでなくてもよく、途中で遮断されていて

第４図及び第５図に示すようにインペラー２が右
ネジで反時計方向に回転する場合流体は上方に流
動するから、気体噴出孔３はインペラー２の下面
側に設ける必要がある。 When the ventilation pipe 1 and the impeller 2 are rotated counterclockwise as shown in FIGS. 2 and 3 with a left-hand thread, the liquid flows downward and therefore a negative pressure is created on the upper side of the impeller 2. Therefore, in this case, the gas ejection holes 3 need to be provided on the upper surface side of the impeller 2 along the impeller 2, for example, in a spiral shape. Conversely, as shown in FIGS. 4 and 5, when the impeller 2 rotates counterclockwise with a right-handed screw, the fluid flows upward, so the gas jet holes 3 need to be provided on the lower surface side of the impeller 2.

２図〜第３図の場合とは逆の時計方向のときに

図及び第５図の構成の場合についても同様であ
る。 Note that when the impeller 2 has a left-hand thread and its rotation direction is clockwise, which is the opposite of the case shown in Figures 2 and 3, the flow of liquid will be in the opposite direction, so the gas jet hole will naturally be set on the opposite side. There is a need to. Fourth
The same applies to the configurations shown in FIG. 5 and FIG.
これら気体噴出孔３，３，３…は小口径に作ら

インペラー２が空洞型の場合に限られる。 It is desirable that these gas ejection holes 3, 3, 3, . Note that the gas ejection holes 3, 3, 3, . . . are provided on the back surface 2a of the impeller 2 in the rotational direction only when the impeller 2 is of a hollow type.

る場合にも通気パイプ１に配することができる。 If the liquid flows upward as shown in FIGS. 4 and 5, it is necessary to place a blind plate 4 at the lower end opening of the ventilation pipe 1 to prevent the liquid from entering the pipe 1. . This blind plate 4 may have a size that matches the diameter of the lower end opening and may be fixed by fitting, adhesive, or other fixing means. Note that the blind plate 4 can be disposed on the ventilation pipe 1 not only in the above case but also in the case where the liquid flows downward.

ずれであつてもよい。 In the device of the present invention, a guide pipe 5 covering the ventilation pipe 1 and the impeller 2 may be provided if necessary. When this is installed, the liquid can be circulated without the need for special power. For example, when combined with a purification device, the contamination of the liquid can be removed, making it suitable for use in aquariums for ornamental fish, etc. be. The shape of this guide tube 5 may be either cylindrical or rectangular.

中に極微粒の気泡を発生させる。 The device of the present invention is used by being connected to a rotating mechanism as described above. The ventilation pipe 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 a negative pressure is generated in the liquid on the back side in the direction of rotation of the impeller 2, which opens the gas intake port 1a.
The gas flowing into the pipe 1 from the gas outlet 3,
It is ejected from 3, 3... and 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.
