<P>PROBLEM TO BE SOLVED: To provide a centrifugal separator automatically discharging a solid content at an appropriate time such that a large amount of solid content is not accumulated in a rotation bowl. <P>SOLUTION: The centrifugal separator is provided with a vertical rotation shaft 2; the rotation bowl 3 integrally and rotatably mounted to the shaft 2; and a treated liquid feeding part 5. In the separator, the treated liquid A fed into the rotation bowl 3 is separated to a light liquid a<SB>1</SB>, a heavy liquid a<SB>2</SB>and the solid content a<SB>3</SB>. Discharge ports 10 for discharging the solid content a<SB>3</SB>deposited on the inner peripheral surface are opened to a peripheral side wall of the rotation bowl 3 in a circumferential direction with a constant interval and valve elements 11 for opening/closing the discharge ports 10 are mounted to an outer side of the respective discharge ports 10 through a spring 12. The valve element 11 usually closes the discharge port 10 by force of the spring 12 and releases the discharge port 10 in resistant to the spring 12 when centrifugal force of a constant or more is applied. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
