<p><P>PROBLEM TO BE SOLVED: To provide a centrifugal separator capable of continuously carrying out centrifugation without accumulating almost no sludge in a separation barrel during centrifugation. <P>SOLUTION: The centrifugal separator comprises a separation barrel 7 which is provided rotatably, has openings at both upper and lower ends, and has inverted cone-like parts that are successively formed within an approximately cylindrical barrel part and the lower part thereof, a rotational driving means M for rotating the separation barrel 7, and an inflow means 6 that is provided through the opening of the upper end part of the separation barrel 7 for discharging a fluid to be treated toward the inner wall surface of the separation barrel 7. The rotational driving means M performs centrifugal rotation of the separation barrel 7, so as to discharge a fluid to be treated toward the inner wall surface. The fluid is thus separated into a separation solution and sludge S. At the same time, the separation solution is spun up along the inner wall surface of the separation barrel 7 so as to be discharged from the opening of the upper end part and thus the separated sludge S is spun down and discharged from the opening of the lower end part of the separation barrel 7. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
