CENTRIFUGE FOR CONCENTRATING SUSPENSIONS Russian patent published in 1995 - IPC

FIELD: separation of materials. SUBSTANCE: centrifuge comprises housing 1 provided with hollow driving shaft 14 having rotor 2 with bottom 3, filtering member 4, and delivery disk 15 at the bottom part. Passage 8 for discharging concentrated phase is defined by disk 9 secured to disk 3 of rotor 2 and made of a resilient material and housing 1 of the centrifuge. The device for directed supplying of the suspension to the surface of filtering member 4 consists of two conical shells 11 and 12 with flanges to define a ring slot converging in the direction of filtering member 4 and connected with the space of branch pipe 5 for supplying suspension. Inner side of housing 1 and outlet part of the ring slot are interconnected through shell 13 made of a resilient material. Rotor 2 is set in bearing supports 16 and 17, the bottom of the rotor being provided with journal 18 whereto rotor ring 19 is secured. Stator 20 is secured to housing 1 coaxially to the rotor. Disk 9 is made of a resilient material. The thickness of the disk can decrease in the direction of periphery. EFFECT: improved design. 2 cl, 1 dwg
