CENTRIFUGAL WITH ADDITIONAL SECTION OF ROTOR Russian patent published in 2004 - IPC

FIELD: mechanical engineering; centrifuges for separation of suspensions under action of centrifugal forces. SUBSTANCE: proposed centrifuge contains rotor consisting of two parts. First part rotor is designed for settling heavy fraction of suspension and second part, made in form of screen, drum, for filtration of thickened heavy fraction. Conveyor installed in first part of rotor service to transport heavy fraction along first part to outlet and to deliver thickened heavy fraction into second part of rotor and it is provided with hub to which second part is connected. Accelerator for tangential acceleration of thickened heavy fraction is installed at inlet of rotor second part. Axial blade of conveyor for displacing heavy fraction along first part of rotor toward outlet is installed on hub. Auger blades are secure don outer surface of rotor first part, said blades being designed for displacing heavy fraction along inner surface of second part of rotor from inlet to outlet for discharging. EFFECT: increased capacity of centrifuge, reduced liquid content in heavy fraction. 13 cl, 14 dwg
