Solid bowl centrifuge for the separation of small solids particles

Abstract

Abstract 1. Bowl centrifuge for separating fine solid particles, in particular amalgam particles, from waste water, with a centrifuge drum (44), which comprises : a peripheral drum wall (46), a drum base (84) and a blocking flange (48) supported by the free end of the peripheral drum wall (46) and pointing radially inwards, which flange defines an overflow opening (50) ; with a drive shaft (38) supporting the centrifuge drum (44) ; and with a conduit (74) supplying the waste water, which is guided in the axial direction into the inside of the centrifuge drum (44) and compared with the axial dimension of the centrifuge drum (44) preferably ends at a short distance above the drum base (84) and furthermore is connected to an inlet channel (18) of the centrifuge housing (12), characterised in that at its discharge end, the conduit (74) is connected to a guide shaft (62, 64) extending in the radial direction, whereof the discharge end is at a greater distance from the drum axis than the edge of the overflow opening (50) and that the blocking flange (48) is equipped on its end face remote from the inside of the drum with pump vanes (52), which rotate in an outlet chamber (22) of the housing (12).
