  • Centrifugal separator
    Patent number: 5762800
    Abstract: A centrifugal separator has a housing with a generally cylindrical inner surface defining an inner chamber. A hollow rotor is disposed within the chamber for rotation therein. At least one inlet is provided for introducing a liquid mixture into the annular volume between the rotor and the housing, where it is then directed into the rotor. An upper rotor assembly separates the liquid mixture by phase densities with the disparate components directed to respective outlets. In one embodiment of the invention, the upper rotor assembly includes an easily removable weir ring to facilitate "tuning" of the separation process. The rotor of the separator is mounted on a unitary rotor shaft that extends axially through the separation chamber to upper and lower bearing assemblies in the separator housing.
    Type: Grant
