Claims (6)
- 上端に吐出口を形成した上部パイプと下端に吐出口を形成した下部パイプを外周に吸込口を形成したケーシングを間に設けて水槽内に立てらせるとともに、上部及び下部パイプ内に捩じり方向を相反させたブレードを有するインペラを配置し、インペラを回転させてケーシングの吸込口から吸い込んだ水を上部及び下部パイプの吐出口から吐出させる水槽内対流惹起装置において、上部パイプの吐出口を水面に平行な方向に誘導し、かつ、上記したケーシングを、中央に仕切板を設けてその上下に隔絶された二つの吸込口を確保して吸込口の上下を上方及び下方に径が漸細してそれぞれ上部及び下部パイプに接続される外郭板を設け、外郭板の最大径を仕切板の径よりも小さくしたことを特徴とする水槽内対流惹起装置。
- 上部パイプに取り付けられた正逆回転可能な電動機で駆動される駆動軸がケーシングを通過して上部及び下部パイプを挿通しており、この駆動軸に各々のインペラが取り付けられる請求項1の水槽内対流惹起装置。
- 仕切板は円形をしており、かつ、外郭板が上部及び下部パイプに向かって径が漸細するベルマウス形状をしているとともに、仕切板の中央上下に外周に向かって高さが漸低する誘導マウンドを形成し、外郭板と誘導マウンドの間を複数の独立したスペーサで隔てて吸込口につながる流路とした請求項1又は2の水槽内対流惹起装置。
- スペーサが平面視で所定の方向に湾曲している請求項3の水槽内対流惹起装置。
- 上部パイプの上方に一定の間隔をあけて上部パイプよりも径の大きな消波兼渦消板が複数の独立したステーで接続されており、ステーの間を上部パイプの吐出口とするとともに、消波兼渦消板の下面に外周に向かうほど高さが漸低する円形の整流マウンドを形成した請求項1〜4いずれかの水槽内対流惹起装置。
- ステーが平面視で所定の方向に湾曲している請求項5の水槽内対流惹起装置。
