Abstract
This invention is drawn to a high-speed centrifugal extractor having improved weirs for selectively separating a heavy liquid and a light liquid. Each of the selection weirs has a double tube structure consisting of an outer cylinder extending from a rotor peripheral wall towards a rotor rotary shaft and an inner cylinder which is inserted into the outer cylinder through the rotor peripheral wall in such a manner that the insertion length of the inner cylinder can be varied. The heavy liquid selection weir has a heavy liquid withdraw port at the wall of the outer cylinder positioned inside the heavy liquid phase, while the light liquid selection weir has a light liquid withdraw port at the wall of the outer cylinder positioned inside the light liquid phase. By varying the insertion length of the inner cylinder into the outer cylinder, the position of an interface at which the heavy and light liquid phases are separated inside a rotor can be changed.
