Description
Claims (5)
- 汚泥が流通可能な空洞部及びこの空洞部から汚泥を放出する排出口が形成され、横軸に配置された中空軸と、この中空軸を回転自在に支持する支持手段と、前記中空軸の外周部に設けられ軸方向に汚泥を搬送可能な排出手段と、この排出手段よりも半径方向外方に前記中空軸とほぼ同軸に配置され中空軸とは異なる回転速度で回転可能なドラムとを有し、このドラムは、フィルタと、このフィルタの外径側であって円周方向に間隔をおいて多数配置され、半径方向位置が外側になるに連れて前記ドラムの回転方向に傾く前向き羽根とを有することを特徴とする遠心脱水装置。
- 前記多数の前向き羽根の傾き角θは、半径方向線から計って、θ=135°〜150°の範囲にあることを特徴とする請求項1に記載の遠心脱水装置。
- 前記フィルタは、円筒面に形成された薄板に多数の細孔を形成して作成されており、この細孔はフィルタの円筒軸に対して直角な方向に長い長孔であり、この細孔の長手方向の長さが前記多数の羽根の羽根間距離にほぼ等しいことを特徴とする請求項1に記載の遠心脱水装置。
- 前記排出手段は、前記中空軸と一体的に形成されたらせん状であって複数条の長さを有するスクリューであることを特徴とする請求項1に記載の遠心脱水装置。
- 前記排出手段は、前記中空軸に対して軸方向の相対位置を可変であり、この排出手段を軸方向に駆動する駆動手段を備えたことを特徴とする請求項1に記載の遠心脱水装置。
