SEDIMENTATION CENTRIFUGE Russian patent published in 2002 - IPC

FIELD: equipment for separation of suspensions under the effect of centrifugal force. SUBSTANCE: the sedimentation centrifuge has a rotor, a worm positioned inside the rotor and having a drum with at least a single spiral secured on it, and a guide partition between its spires. It is located in the zone between the heavy fraction inlet and outlet ports in a spaced relation to the rotor. The guide partition is made in the form of a spiral-like rib for entrainment and transportation of heavy fraction similarly to the worm spiral spires. This partition has a height lesser than that of the spiral spire, and a peripheral part describing the enveloping surface at worm rotation. EFFECT: enhanced efficiency of separation of source material due to improved conditions of transportation of heavy fraction. 10 cl, 17 dwg
