Abstract:
A centrifuge for receiving a feed flow and separating solids and liquids in the feed flow, the centrifuge comprising:(a) a tapered porous cone formed of sintered materials having an inside face on a porous wall extending outwardly to a peripheral edge wherein the cone defines an axis of rotation, a specified conic angle and cone length;(b) a power drive operatively connected to the cone to rotate the cone about the axis;(c) a closed housing surrounding said cone and having a fixed internal ring secured to the housing arranged to divide the feed flow introduced into the cone into a solvent flow passing through the wall of the cone, and a solid flow which does not pass through the wall of the cone but which is discharged over the peripheral edge;(d) an inlet line for delivering a flow of solvent with solids into the cone to impinge on the face of the cone; and(e) a plurality of radially outwardly oriented vanes mounted on said cone at the inside face thereof so that said vanes intercept the flow from the tube to deflect the flow radially outwardly onto the inside face of the cone.
