Abstract
A continuously operating screw ejection centrifugal separator. The drum and the screw are driven by an epicyclic gear train. Changes in torque between the screw and the drum of the centrifuge are measured and the differential speed of the screw and drum is controlled so as to obtain substantially steady state operation of the separator. For the control, a second epicyclic gear train is associated with the first-mentioned epicyclic gear train.
Claims5
In a continuously operating screw ejection centrifugal separator comprising a drum for holding material to be centrifuged and a screw in the drum for advancing separated material toward one end of the drum for the discharge thereof from the drum, an epicyclic gear train operatively connecting the drum and the screw for rotating both the drum and the screw, and a drive means for driving the epicyclic gear train, the improvement which comprises a second epicyclic gear train associated with the first-mentioned epicyclic gear train, the second epicyclic gear train having a drive shaft operatively connected with a control means for measuring torque between the drum and the screw and control of the rotation of the drum and the screw.
