Abstract
A decanter centrifuge enables separation of solid and liquid components from a feed solution containing suspended solids by application of centrifugal force. The decanter centrifuge has at least one disc-like dip weir fixed to the outside surface of a cylindrical portion of a screw conveyor on a solid component discharge port side located away from a feed solution supply port. A predetermined distance is provided between the outermost periphery of the dip weir and the adjacent internal surface of a coaxially rotating outer shell or bowl. An overflow hole is formed adjacent the internal periphery of the disc-like dip weir to pass liquid and the outermost edge of the overflow hole is located closer to the rotational axis of the screw conveyor than the outermost edge of a liquid component discharge port. The liquid component in the incoming feed solution is thus reduced efficiently, as the feed solution passes through the centrifuge, by the separation action facilitated by the disc-like dip weir having the overflow hole.
