せしめるようになす。[Means for solving the problem] The liquid is stirred by a stirring blade at the tip of the drive shaft passing through the hollow shaft, and the negative pressure at the tip of the stirring blade generated by stirring the liquid is utilized. The gas is mixed into the liquid through the hollow shaft, and the lower end of the gas-liquid suction pipe, which opens above the liquid surface, is arranged to open at the negative pressure generating part in the liquid at the tip of the stirring blade. Gas is inhaled into the liquid through the suction pipe.
以下本考案を図面に示す実施例にもとづいて説

羽根３を所要回転数にて回動するようになす。 In the figure, 1 is a hollow shaft, and 2 is a drive shaft that is rotatably inserted through the hollow shaft 1. A desired stirring blade 3 is provided at the lower end of this drive shaft 2, and the upper end of the drive shaft is provided with the upper part of the hollow shaft. A motor 4 disposed in the stirrer 4 is directly or indirectly connected, and the stirring blade 3 is rotated at a required number of revolutions by driving the motor.
また中空軸１の下端は液中にて開口され、かつ
液面上の任意位置に気体吸入孔５が穿孔される。
従つてこの撹拌羽根３の回動にて液体中にしかも
撹拌羽根の先端部分で負圧が発生すると、この気

ものである。 Further, the lower end of the hollow shaft 1 is opened in the liquid, and a gas suction hole 5 is bored at an arbitrary position above the liquid level.
Therefore, when negative pressure is generated in the liquid and at the tip of the stirring blade due to the rotation of the stirring blade 3, the gas sucked in from the gas suction hole 5 flows down inside the hollow shaft and flows into the liquid from the lower end opening. The liquid is released into the liquid, pulverized by a stirring blade, and mixed into the liquid as fine bubbles.

と吸入管とをステー７にて固定することがある。 Further, by utilizing the negative pressure at the tip of the stirring blade, gas is also sucked in from the hollow shaft and the gas suction pipe 6 installed elsewhere. This suction pipe 6 may be arranged in a substantially vertical direction as shown in FIG. Two or more of them are placed side by side, and in the same way, the opening at the lower end is positioned at the negative pressure generation site, and the opening at the upper end is positioned above the liquid level. At this time, at least the lower end of the air suction pipe should be parallel to the flow direction of the liquid generated by the stirring blade, and the opening in the liquid should be in front of the tip of the stirring blade, that is, in the downstream direction from the stirring blade of the flowing liquid. It is desirable to become. Note that when the air suction pipe is arranged along the hollow shaft, the hollow shaft and the suction pipe may be fixed with a stay 7.

Therefore, by arranging the air suction pipe separately from the hollow shaft as in the present invention, a large amount of gas can be efficiently blown into the liquid using only the negative pressure generated in the liquid without using any other gas pushing means. .
