本発明は、ポンプの吐出流を利用して、ポンプと連通し
た噴出ノズル部に空気を供給して、水槽内に気泡水流を
噴出する気泡水流発生装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a method for generating a bubble water flow that uses the discharge flow of a pump to supply air to a jet nozzle portion communicating with the pump to spray a bubble water flow into an aquarium. It is related to the device.
従来の技術

開昭６３−１８８０２７号公報）。The mixing chamber 3 consisted of an ejection nozzle 4 and a mixing nozzle 5 having horizontal axes, and a mixed air suction part 6 whose axis was orthogonal to the two nozzle axes (for example, 188027).
発明が解決しようとする課題

らこの水と空気の接触面積は小さいため、大きなエネル
ギの授受は行なわれず、微細化には限界があった。Problems to be Solved by the Invention However, in the above configuration, the intake air is sucked in from around the jet water by the jet action of the water flow, so that only relatively large bubbles are generated. This is because the air mass initially comes into contact with the water flow in the laminar diffusion layer around the jet water where the flow velocity is slow, so the air mass is reduced in size by the laminar flow shearing force here. However, since the contact area between water and air is small, large amounts of energy cannot be exchanged, and there is a limit to miniaturization.
次に空気塊は層流境界層から乱流領域に移送され、ここ
で水粒子との運動量交換による乱流剪断力により微細化
されるわけであるが、−度形成された空気塊をこわすに
は非常に大きなエネルギを必要とするため、微細化には
限界があった。Next, the air parcel is transferred from the laminar boundary layer to the turbulent region, where it is atomized by turbulent shear force due to momentum exchange with water particles. requires a large amount of energy, so there is a limit to miniaturization.

On the other hand, on the downstream side of the jet nozzle 10, a small-diameter pipe 11 serving as an air supply means is provided in a camphor that opens into the water tank 7. The small diameter pipe 11 is provided with an air pump 12 and a valve I3. Further, a wire mesh 14 which is a porous body is provided downstream of the small diameter pipe 11.

Air is supplied into the water tank 7 from the small diameter pipe 11. The air masses supplied in this way are blown away by the dynamic pressure energy of the water flow and become micro air masses, which are mixed with the water flow and collide with the wire mesh 14, and the micro bubbles are further divided into micro bubbles and sent to the aquarium. Sent. These microbubbles make the inside of the aquarium cloudy. Furthermore, by adjusting the amount of air from the air pump 12, the amount of bubbles can be changed, that is, the degree of cloudiness can be adjusted.
