A defoaming blade 4 is provided at the tip of the rotating shaft 31, and a mesh cylinder 5 surrounding the defoaming blade 4 is provided outside the rotation radius of the defoaming blade 4. A wall surface 9 is provided on the outside for aggregating the bubbles 6a and droplets 7 that are blown away and made fine by the defoaming blade 4, and a liquid receiver 10 for the agglomerated liquid falling from the wall surface 9 is provided below the wall surface 9. The structure includes an outlet 11 for collecting the flocculated liquid accumulated in the liquid receiver 10 and flowing it downward into the stirring tank 1.
前記網目円筒５および前記壁面９は第２図に示すように
２本以上の保持棒１２により同心状に支持されている。The mesh cylinder 5 and the wall surface 9 are supported concentrically by two or more holding rods 12, as shown in FIG.

に向かって僅かに傾斜していることが好ましい。The wall surface 9 and the liquid receiver 10 are shown in FIGS. 3 and 4.
As shown in the figure, the liquid receptacle 10 connected to the wall surface 9 has an approximately L-shaped donut shape in cross section so as to be able to collect the aggregated liquid. 6, and is equipped with the outlet 11 that collects the accumulated liquid and causes it to flow down from a certain point. That is, it is preferable that the liquid receiver 10 be slightly inclined toward the direction of the outlet 11.
また、前記網目円筒５は前記液受け１０の上方に位置し
ており、該網目円筒５に衝突して液化したものを前記液
受け１０に集めることができるようになっている。Further, the mesh cylinder 5 is located above the liquid receiver 10, so that the liquid that collides with the mesh cylinder 5 and becomes liquefied can be collected in the liquid receiver 10.

状が望ましい。Although the shape of the defoaming blade 4 is not particularly limited,
In order to be able to suck in the bubbles 6 from above and below the central portion of the blade 4, a structure is adopted in which a blower plate is provided only at the tip of the blade, and the blower plate preferably has an appropriately curved shape.
上記のように構成された前記消泡装置８の作用について
説明する。The operation of the defoaming device 8 configured as described above will be explained.
前記攪拌槽１内に入れられた発泡性液体（液体同士又は
液体と固体の混合物を含む）は、前記槽撹拌機３によっ
て攪拌混合が行われるが、発泡性であるため泡が槽内の
上方の空間に一杯になる。The foamable liquid (including a mixture of liquids or a mixture of a liquid and a solid) placed in the stirring tank 1 is stirred and mixed by the tank stirrer 3, but since it is foamable, bubbles are generated upward in the tank. It fills up the space.
前記消泡装置８の攪拌羽根４は、前記槽攪拌機３の回転

。この微細化した前記泡５ａ、又は前記液滴７は前記壁
面９にぶつかって凝集し、液流となってＵ状ドーナツ型
の前記液受け１０に受は止められ、更に液流となって前
記流出口１１より前記発泡性液体の表面に流れ落ちる。The stirring blade 4 of the defoaming device 8 sucks the foam 6 generated by the rotation of the tank agitator 3 from above and below the stirring blade 4, and as shown in FIG. 5, the stirring blade 4 turns the foam 6 into fine particles. At the same time as the bubbles 6a or droplets 7 are made smaller, the bubbles 6a or droplets 7 are blown through the mesh cylinder 5. The miniaturized bubbles 5a or the droplets 7 collide with the wall surface 9 and aggregate, become a liquid stream and are stopped by the U-shaped donut-shaped liquid receiver 10, and further become a liquid stream to form the liquid receiver 10. It flows down from the outlet 11 onto the surface of the foamable liquid.
従来は液滴でも微細な状態のまま放出されていたために
、該液滴は大きい泡に乗せられ吸収されがちであったが
、本実施態様のように完全な液流となることによって、
該液流は前記泡６に吸収されることなく大きな泡も破っ
て流下する力をもっている。また、従来のように微細化
した前記泡６ａ及び前記液滴７がそのまま槽内に飛散し
ないので、大きな泡６は微細な前記泡６ａ及び前記液滴
７を吸収しないために、従来よりも乾いた状態とも言え
る状態であって、前記泡６の強度も弱くつぶれ易い状態
にあると言える。Conventionally, even droplets were released in a fine state, so the droplets tended to be carried by large bubbles and absorbed, but by creating a complete liquid flow as in this embodiment,
The liquid stream has the power to break even large bubbles and flow down without being absorbed by the bubbles 6. In addition, since the fine bubbles 6a and the droplets 7 do not scatter into the tank as they are in the conventional case, the large bubbles 6 do not absorb the fine bubbles 6a and the droplets 7, making the bubbles dryer than before. This can be said to be a state in which the bubbles 6 have a weak strength and are easily crushed.
なお、前記流出口１１から流れ落ちる凝集液と下方の液
面との衝突による泡立ちをも考慮すると、前記流出口１
１を前記攪拌槽１の内壁まで届くように延ばした構成に
することにより、液流ば槽壁を伝って流れ落ちて、穏や
かに槽の液に戻り、前記泡立ちは防止できる。In addition, if we also take into consideration the bubbling caused by the collision between the flocculated liquid flowing down from the outlet 11 and the liquid surface below, the outlet 1
By configuring the stirring tank 1 to extend so as to reach the inner wall of the stirring tank 1, the liquid flows down the tank wall and gently returns to the liquid in the tank, thereby preventing the bubbling.
このようにして、液位の低下は効果的に防止されるので
、液位一定状態で良好な攪拌・混合が行なわれることに
なる。In this way, a drop in the liquid level is effectively prevented, so that good stirring and mixing can be performed with the liquid level constant.
本発明は第１図から第５図に示した実施態様に限るもの
ではなく、例えば、前記網目円筒５を二重に設けたり、
また、前記壁面９の形状など種々変更可能であることは
勿論である。The present invention is not limited to the embodiments shown in FIGS. 1 to 5, and for example, the mesh cylinder 5 may be provided twice,
Furthermore, it goes without saying that the shape of the wall surface 9 can be changed in various ways.

くつぶれ易い状態にすることができる。As described above, in the defoaming device of the present invention, a mesh cylinder surrounding the defoaming blade is provided outside the rotation radius of the defoaming blade rotationally driven by a rotating shaft, and the mesh cylinder surrounding the defoaming blade is provided outside the mesh cylinder. A wall surface is provided to aggregate the fine bubbles and droplets blown away by the foam blade, and a liquid receiver is provided below the wall surface for the agglomerated liquid that falls from the wall surface, and the aggregated liquid accumulated in the liquid receiver is collected and stirred. Since the structure is provided with an outlet for flowing downward into the tank, the foam that has been made fine by the defoaming blade,
Alternatively, the droplets can be collided with the wall surface and aggregated, collected in the liquid receiver as a liquid stream, and further effectively returned to the foamable liquid through the outlet as a liquid stream. In addition, since the fine bubbles and droplets do not scatter into the tank as they are in the conventional method, the large bubbles are kept relatively dry because they do not absorb the fine bubbles and droplets, and the foam is weak and easily crushed. can be in a state.
