Abstract
【解決手段】フロントハブ8における各液体排出口6の半径方向外側の位置に、ダム7の溢流縁部7aの上を溢流してボウル2内から排出された分離液を回収する分離液噴射装置9を取り付けた。この分離液噴射装置9は、回収した分離液を内部において一時的に貯留する分離液貯留室12を有するとともに、側部9aに、ボウル2の回転方向と反対の方向へ向かって開口し、分離液貯留室12内の分離液を外部へ噴射する噴射ノズル10が配置されている。

Claims (4)
- 中空のボウルと、その内部においてボウルと同軸的に配置されたスクリューコンベアとを有し、これらを回転させることにより、ボウル内に導入された処理原液を、遠心力により液体と固形分とに分離し、ボウルに対して差速をもって回転するスクリューコンベアにより、分離した固形分を、ボウルの一方の端部に形成されている固形分排出口へ向かって搬送してボウル外へ排出するとともに、分離した液体を、ボウルの反対側の端部を構成するフロントハブに複数形成されている液体排出口からボウル外へ排出するように構成された遠心分離機において、
各液体排出口には、ボウル内の液面高さを規定するダムが配置され、
液体排出口の半径方向外側の位置において、ダムの溢流縁部の上を溢流してボウル内から排出された分離液を回収する分離液噴射装置が、フロントハブに取り付けられ、
分離液噴射装置は、回収した分離液を内部において一時的に貯留する分離液貯留室を有するとともに、いずれかの側部或いは底部に、ボウルの回転方向と反対の方向へ向かって開口し、分離液貯留室内の分離液を外部へ噴射する噴射ノズルが配置されていることを特徴とする分離液噴射ノズル付き遠心分離機。 - 分離液貯留室内に貯留される分離液の過剰分を外部へ放出する放出口が、分離液噴射装置における噴射ノズルよりも半径方向内側の位置に形成されていることを特徴とする、請求項1に記載の分離液噴射ノズル付き遠心分離機。
- 放出口の下縁が、ダムの溢流縁部よりも半径方向外側に位置するように構成されていることを特徴とする、請求項2に記載の分離液噴射ノズル付き遠心分離機。
- 噴射ノズルが、ダムの溢流縁部から、フロントハブの外周までの距離の50%の位置よりも半径方向外側の位置に配置されていることを特徴とする、請求項1〜3のいずれかに記載の分離液噴射ノズル付き遠心分離機。
