Abstract:
A machine for separating a mixture having a first fluid and a second fluid of a density different from the density of said first fluid, said machine comprising:a housing;a separation chamber having a central axis and positioned within said housing, said, separation chamber having an outer wall and said separation chamber being sized to receive and contain a volume of said mixture to be rotated within said separation chamber with a first volume of said first fluid and a second volume separated from said first volume, said first volume and said second volume having a boundary, there between spaced from said central axis of said separation chamber a boundary, distance;fin means attached to said outer wall of said separation chamber to rotate therewith and to urge said mixture and at least one of said first volume and said second volume to rotate with said separation chamber;an inlet connected to supply said mixture from exterior said housing to said separation, chamber;a first weir connected to said outer wall and sized to extend toward said central axis and spaced from said central axis a first distance selected to be less than said boundary distance to define a first outlet from said separation chamber through which one of said first fluid and said second fluid exits from said separation chamber;motor means connected to rotate said separation chamber, said motor means including a chamber portion thereof positioned relative to said separation chamber and configured to extend away from said central axis a channel distance to define a channel between said chamber portion and said outer wall;a second weir connected to one of said chamber portion and said outer wall and sized to extend toward said central axis and spaced from said central axis a second distance selected to be less than said channel distance to define a second outlet through which the other of said first fluid and said second fluid exits from said separation, chamber.
