  • Centrifugal separator with a vertical axis and a skimmer
    Patent number: 4718887
    Abstract: In a vertical centrifugal separator having a basket and a skimmer, laminar flow occurs at the bottom of an upper skimming disk and extends over the skimming-disk shaft into an annular catch chamber. Liquid-diversion channels leads from the catch chamber into an intake. Although the product is fed into the intake under higher-than-atmospheric pressure, the catch chamber, which is at atmospheric pressure, empties through the liquid-diversion channels because the high rate of flow in the intake produces an injector effect.
