Abstract

A separating device which utilizes a centrifuge which is driven by a motor for processing liquids enriched with solids by forcing the solids out of the liquid against a peripheral centrifuge wall as a consequence of centrifugal force characterized that a collecting vessel is the centrifuged container. The collecting vessel or centrifuge chamber has a plurality of axially spaced partitions with concentrically arranged openings to form axially spaced chambers which will collect the solids separated from the liquid as the liquid is discharged from the device. In one embodiment, the collecting vessel and centrifuge chamber are a single molded member. In another embodiment, there are two parts, with one being a container-like part receiving an insert having the parititons.
