<p>PROBLEM TO BE SOLVED: To provide a new centrifugal extractor capable of always exactly grasping the temperature of a casing center where a separation drum is contained. SOLUTION: For a centrifugal extractor provided with a rotational axis 3 to rotate a separation drum 2 at the axis of the separation drum 2 to separate a mixed solution of heavy material and light material into heavy material and light material using a centrifugal force, a thermocouple 20 to measure the temperature of the axis part of the separation drum 2 is coaxially embedded in the rotation axis 3. Electric signal from that thermocouple 20 is taken from the brush electrode 25 provided around the rotational axis 3.</p> |
