SEPARATION ROTOR FOR CENTRIFUGAL EXTRACTOR

摘要

PURPOSE:To achieve miniaturization and wt. reduction by forming a stirring region where an impeller can be rotated to the bottom part of a rotor and forming the blade shape of the impeller so as to conform to the inclined surface of the bottom part of a casing. CONSTITUTION:The supply port 18a of a heavy liquid supply part 18 and the supply port 19a of a light liquid supply part 19 are opened to the supply flow passage 20 between the cylindrical part 1a of a casing surrounding a separation rotor 2 and the peripheral surface of the rotor 2 and the heavy liquid and light liquid passing through the supply flow passage 20 are mixed by the peripheral surface of the rotor 2 rotating at a high speed. The liquid mixture reaching the vicinity of a liquid mixture supply port 4 is revolved spirally by the effect of an impeller 16 rotating at a high speed to be sucked in the rotor from the liquid mixture supply port 4 and dispersed under stirring by the impeller 16 to be sent in a spiral liquid passing region 7 from a stirring region 17 and separated into a heavy liquid phase H and a light liquid phase L in a heavy liquid-light liquid drawing-out region 10 by centrifugal force.
