Abstract:
A centrifuge system comprising:(a) a drive rotating at a controlled speed;(b) a centrifuge bowl rotated with the drive;(c) an internally located screw conveyor in said bowl cooperatively rotating therewith wherein said screw conveyor and said bowl provide a scrolling action to help segregate heavier parts of a mixed fluid flow separated in said bowl and screw conveyor;(d) an output power transmission connected to first and second rotatable elongate connective shafts wherein said first connective shaft is connected to and driven by said bowl and said second connective shaft is connected to said screw conveyor, and wherein said output power transmission drives said screw conveyor to enable said screw conveyor to be rotated;(e) wherein said bowl speed is adjustable and said output power transmission cooperatively responds to impart a desired scrolling speed to said conveyor to operatively segregate said heavier parts, wherein said drive speed and cooperative output power transmission control bowl rotation and conveyor scrolling speed for optimum operation; and(f) wherein said output power transmission comprises first and second separately located gearboxes, each of the first and second separately located gearboxes defining an output, and wherein said second gearbox provides a rotation reversal, and wherein said first gearbox has a gear ratio forming a speed differential at the output thereof wherein the first gearbox output comprises said first and second connective shafts.
