Batch centrifuge for a mixture of solid and liquid and skim from molten aluminous metal

A suspended centrifuge apparatus for the removal of liquid from a physical mixture of at least one liquid phase and at least one particulate solid phase, said physical mixture including, inter alia, hot aluminous skim having a liquid aluminum component, said suspended centrifuge apparatus comprising:

• a centrifuge vessel;
• a structural support comprising a means for suspending, for positioning and for rotating a first, compound, arcuate surfaced, linkage component, enabling suspension, positioning and rotation of said centrifuge vessel;
• a second, arcuate surfaced, linkage component mountably and demountably engageable with the first linkage component, having a central axis and attached to said centrifuge vessel;
• said first linkage component and the second linkage component, when fully engaged, forming a linkage interconnection point;
• said centrifuge vessel comprising:
• at least one peripheral opening of controlled extent, a vertical, central axis, said vessel being generally symmetrical about said vertical, central axis, and having walls and a closed bottom with an indentation therein, and
• said central axis of said second linkage component capable of being located coextensive with said vertical, central axis of said centrifuge vessel;
• said centrifuge vessel when loaded, suspended from said structural support and, prior to rotation, assuming an initial, static, vertical axis as measured from said linkage interconnection point;
• said indentation defining a generally conical, rigid, exterior surface of said centrifuge vessel and having a central axis coextensive with said vertical, central axis of said centrifuge vessel, the bottom diameter of said indentation being greater than the upper diameter of said indentation;
• a first, centrifuge vessel, gyration restraint component being a portion of said generally conical, rigid, exterior surface of said indentation on the exterior of said centrifuge vessel;
• a second, centrifuge vessel, gyration restraint component being fixed in space and comprising:
• an exterior surface able to cooperate with a portion of said first, centrifuge vessel, gyration restraint component and having an upper, exterior portion smaller by a predetermined amount than a lower, exterior portion of said first, centrifuge vessel, gyration restraint component;
• and
• during liquid extraction, said suspended centrifuge vessel being positioned with said first, centrifuge vessel, gyration restraint component surrounding proximate a predetermined distance from the cooperating portion of said second, centrifuge vessel, gyration restraint component, thereby enabling, during centrifuging, said vertical, central axis of said centrifuge vessel to be maintained closely to said initial, static, vertical axis measured from said linkage interconnection point;
• whereby, the loaded, suspended, and positioned centrifuge vessel is enabled by a predetermined speed and time of rotation under gyration restraint to expel most of said at least one liquid phase and retain most of said at least one particulate solid phase thereby effectively separating said physical mixture.
