【０００１】
【発明の技術分野】
本発明は、嫌気性の水処理槽内における竪型水中攪拌装置に関するものである。
【０００２】
【従来の技術】
水中攪拌装置において、処理槽の水面の表層に発生する吸込み渦を抑制するための整流板をモータフレームの外周に定着させたものは、従来から存在する（例えば、特許文献1参照）。また、攪拌装置およびドラフトチューブを槽内へ垂設するための支持柱に整流板を固定させたものも、従来から存在する（例えば、特許文献２参照）。

【特許文献２】
特開２０００−２８８５６８号公報 （第２図）
【０００４】
【発明が解決しょうとする課題】
特許文献１および２に記載の装置では、整流板が一定位置に固定されていて上下に位置調整できない構造であるため、予め整流板を必要以上に大きくしなければならず、また、水面の表層に発生するスカムについては槽内水位に適応した有効な吸引除去が得られない。従って、別途装備された散水除去設備等によるシャワリングで除去しなければならないのが現状である。そして整流板に夾雑物が絡み付いた場合その夾雑物を除去するには、特許文献１の構造では攪拌機本体ごと槽内から引揚げなければならないという煩わしさがある。また、特許文献２のようにドラフトチューブの支持柱に整流板を取付けた構造ではドラフトチューブ中心付近での整流効果が乏しくなり、且つ、絡み付いた夾雑物を除去するためには、支持柱から整流板を取外して槽内から取出すことが必要となる。
【０００５】
本発明の目的は、整流板を槽外から上下に位置調整できて比較的小さな整流板で適正な整流効果が得られ、更に槽内水位に適応した有効なスカムの吸引除去が行われ、散水除去設備等を別途装備する必要がなく、また、整流板に夾雑物が絡み付いた場合には整流板のみを迅速且つ容易に槽内から引揚げることのできる、水処理槽内における竪型水中攪拌装置を提供することにある。
【０００６】
【問題を解決するための手段】
本発明の請求項１記載の水処理槽内における竪型水中攪拌装置では、槽内の支持体によって竪型のドラフトチューブを水処理槽上のフロアーに開設された導下口直下の水処理槽内の水面下に水没状態で支承させ、竪型水中モータによって駆動される攪拌用のプロペラを上記ドラフトチューブの上端開口部へ対向させ、上記導下口より導下された縦杆により、攪拌用のプロペラを嵌着した上記竪型水中モータの上方において、放射方向に張設された複数の板により上下端面が開放状態の整流路に区画形成された整流板が昇降自在に支承されるよう構成した。
【０００７】
また、本発明の請求項２記載の水処理槽内における竪型水中攪拌装置では、水処理槽上のフロアーに開設された導下口より導下された縦杆によって竪型のドラフトチューブを水処理槽内の水面下に水没状態で垂設支承させ、竪型水中モータによって駆動される該モータ軸下端に嵌着された攪拌用のプロペラを上記ドラフトチューブの上端開口部へ対向させ、攪拌用のプロペラを嵌着した上記竪型水中モータの上方において、放射方向に張設された複数の板により上下端面が開放状態の整流路に区画形成された整流板が昇降自在に支承されるよう構成した。
【０００８】
更に本発明の請求項３記載の水処理槽内における竪型水中攪拌装置では、請求項１または２記載の発明を前提として攪拌用のプロペラを竪型のドラフトチューブの上端開口部へ対向させる手段として、上記ドラフトチューブの上端開口部と導通する攪拌機収容筒が該ドラフトチューブの上端縁に接続された、攪拌機収容筒の上端開口周縁部を整流板の最降下限位置とする支承座に形成し、竪型水中モータのモータ軸下端に上記プロペラを装着した攪拌機を縦杆により攪拌機収容筒内へ装脱自在に嵌装された態様とした。
