Abstract
This disclosure relates to a centrifugal separator for separating suspended substances from a liquid such as the waste water of a ship. The centrifugal separator comprises a base frame, a tubular drive shaft journalled vertically on the frame and adapted to be driven, a cylindrical rotor fixed coaxially to the shaft adjacent one end thereof, a circumferential chamber formed inside the rotor around the shaft and the chamber having upper and lower ports adjacent the shaft, a pipe fixed coaxially inside the shaft, an inner passage formed inside the pipe, an annular passage formed inside the shaft and around the pipe, each of the passages communicating with one of the ports, axially aligned first and second headers formed on the frame, each of the headers having a port, the other end of the shaft extending rotatably into the first header so that annular passage opens in the first header, and one end of the pipe extends rotatably through the first header and into the second header so that the inner passage opens in the second header. The circumferential chamber is formed by an outer cylindrical wall and an inner conical wall, the diameter of the conical wall increasing in the downward d…
