A liquid/solids separation device is provided in which a tubular feed chamber (5) extends vertically downwards within a container. The feed chamber is open at its lower end (28) which is located well above a central outlet (4) in the bottom of the container to provide for a compacted zone of dewatered solids located below the lower end of the feed chamber. A usually semi-circular furcated mixing rake (26) is positioned within the feed chamber and a dewatering ring (24) is positioned around the lower end of the feed chamber. An inlet to the feed chamber in the upper region directs inlet slurry in a circumferential direction by conveniently making the inlet pipe (9) follow a tangential path or that of an involute, relative to the tubular feed chamber. Means (15) are also provided for introducing clarified liquid from the top region of the container into the inlet slurry. Thickened underflow material is withdrawn from the base of the container through a sleeve and clarified liquor exits from the top of the container. |
