Centrifugal solids dryer
First Claim
1. IN A CENTRIFUGE THE COMBINATION COMPRISING A FIRST ROTOR HAVING A PERFORATE WALL, A SECOND ROTOR HAVING A FRUSTO-CONICAL PERFORATE WALL AND DISPOSED WITHIN SAID FIRST ROTOR, SAID FIRST ROTOR HAVING AN OPEN END FOR THE DISCHARGE OF SOLIDS, SAID SECOND ROTOR HAVING ITS LARGER END FACING THE OPEN END OF SAID FIRST ROTOR AND TERMINATING AXIALLY INWARD OF SAID OPEN END, SAID SECOND ROTOR HAVING AN OUTER PERIPHERY TERMINATING CLOSE TO SAID FIRST-NAMED WALL, MEANS FOR ROTATING SAID ROTORS AND MEANS FOR RECIPROCATING SAID SECOND ROTOR, THE MEANS FOR ROTATING THE SECOND ROTOR EXTENDING AWAY FROM THE OPEN END OF THE FIRST ROTOR, AN AXIALLY TRANSVERSE INNER SURFACE ON THE SMALLER END OF THE SECOND ROTOR, AN AXIAL, NON-ROTATING FEED CONDUIT PROVIDING A CYLINDRICAL SPACE FOR THE PASSAGE OF FEED AND EXTENDING IN THROUGH THE OPEN END OF THE FIRST ROTOR AND HAVING ITS OUTLET END POSITIONED ADJACENT TO AND SPACED FROM SAID TRANSVERSE INNER SURFACE, AN OUTWARDLY EXTENDING ANNULUS RIGIDLY SECURED ABOUT THE OUTLET END OF SAID FEED CONDUIT TO PRESENT AN ANNULAR SURFACE OPPOSING SAID FIRST-NAMED SURFACE, THE PERIPHERY OF SAID ANNULUS BEING UNIFORMLY SPACED FROM THE INNER SURFACE OF THE SECOND ROTOR, MEANS HOLDING SAID SECOND ROTOR AND SAID FEED CONDUIT AGAINST RELATIVE AXIAL MOVEMENT, A CAKE-LEVELING RING MOUNTED ON SAID SECOND ROTOR AND SPACED OUTWARD FROM THE LARGER END THEREOF AND HELD AGAINST RELATIVE AXIAL MOVEMENT WITH RESPECT THERETO, THE RING HAVING A CIRCULAR OUTER EDGE AND BEING OF LESSER RADIUS THAN THE INNER SURFACE OF THE WALLOF THE FIRST ROTOR TO PROVIDE A SPACE BETWEEN SAID RING AND SAID SURFACE FOR THE PASSAGE OF SOLIDS, WHEREBY THE ANNULUS ABOUT THE OUTLET END OF THE FEED TUBE AND THE CAKE-LEVELING RING BOTH BEING HELD IN UNCHANGING AXIAL RELATION TO THE SECOND ROTOR SERVE TO DISTRIBUTE THE SOLIDS EVENLY OVER HE PRFORATE WALLS OF THE ROTORS WITHOUT PLUGGING OR UNBALANCE.
