Abstract

In a centrifuge device whose purpose is in particular the separation of amalgam from waste water generated in dentist' offices, the following is provided in order to improve the determination of the filling level in a collecting tank downstream from a centrifuge, to obtain better utilization of the container volume, to reduce the residual moisture in the separated solids, and to simultaneously eliminate the repumping means which operate between the collecting tank and the centrifugal. The collecting tank is detachably attached to a centrifuge drum and rotates together with the centrifuge, with measures being taken for separating the clean-water space from the centrifuge drum, there is also provided a transport container which can be detached from the device together with a collecting tank, which container can, when the collecting tank is in it, be closed by means of a cover which, when it is not in use, is detachably attached to the transport container. The device can also be designed in such a manner that a liquid/gas/solids mixture, generated, for example, in the oral cavity of a dentist's patient, can be fed to it simultaneously for the purpose of phase separation.
