Abstract

【課題】曝気作用の向上と起動時の負荷を低減させると共に異物閉塞を防止し、メンテナンス作業の軽減と製造およびランニングコストを低減し得る水中曝気装置を提供する。 【解決手段】通液路４ｗと通気路４ａを区画する隔壁がブレード４ｃに形成した羽根車４を吸気口５ｓを穿設した中間プレート下面５ｄと吸液口７ｓを穿設したサクションカバー上面７ｕ間に回転自在に介装させガイドケーシング６内に収容し、ブレード背面４ｒ側隔壁外周先端部分の通液路４ｗと通気路４ａを連通４ｈし、通液路４ｗ外周部に中間羽根４ｍを設け、ブレード下端面４ｄとサクションカバー上面７ｕとの隙間を吸液口７ｓ部で大きくガイドベーン舌部を含め外周に向けて狭く擂鉢状に形成し、ガイドケーシングの下壁６ｄ外周下端面にスタンド凸子８およびストレーナ突起９を一体的に複数凸設し、気液吐出路間の上壁上面６ｏ形状を外周に向けて末広がり状の下り勾配傾斜面に凹設した。
