Abstract
A separator device comprises a cylindrical separation chamber within which a motor-driven rotor is situated. The rotor has vanes. In operation, an inflowing mixture enters through an inlet and is subjected to centrifugal force imposed by the rotation of the rotor. A lighter liquid fraction leaves through an annular outlet, and a heavier liquid fraction leaves through an annular outlet. Solids pass through a screen to a region where rotational flow is reduced or absent. The solids in the region are fluidized by liquid passing through the screen, and are extracted from outlets. Control means is provided to control operation of the device in response to changes in the incoming mixture.
