SUSPENSION SEPARATING CENTRIFUGE Russian patent published in 2002 - IPC

FIELD: units for separation of suspensions; sewage treatment. SUBSTANCE: proposed centrifuge has housing with rotor mounted inside it; housing consists of cylinder and truncated cones mounted on either side by their larger bases. One cone is provided with ports for discharge of coarse dispersed fraction of solid phase; other cone has ports for discharge of highly dispersed fraction of solid phase. Coaxially located in rotor is screw feeder provided with hollow drum and turns of spiral secured on it. Parts of screw feeder located in cones of rotor have opposite direction of spiral turns. Turns of spiral on part of screw feeder located in cylinder have same direction of turns as those on part of screw feeder inside truncated cone with ports for discharge of highly dispersed fraction. Diameter of larger base of truncated cone with ports for discharge of coarse dispersed fraction is lesser that diameter of cylinder. Rotor is provided with feed pipe and centrifugate discharge unit. EFFECT: enhanced degree of classification of solid phase by degree of dispersivity; reduced power requirements for transportation of sediment. 2 cl, 2 dwg
