  • Patent number: 5160311
    Abstract: Centrifugal separator having a discharge device for the transformation of kinetic energy of a liquid rotating in a chamber around a rotational axis to pressure energy. The device comprises an element for the discharge of liquid out of the chamber, which element has a surface (20) surrounding the rotational axis arranged to be so located in the rotating liquid body that liquid flows in a predetermined direction along and in contact with the surface (20). The discharge element forms at least one outlet channel (21), which has an inlet opening (22) located in said surface (20) and which from this inlet opening (22) extends in the flow direction. Seen in the flow direction the inlet opening (22) is delimited by two opposite side edges (23, 24) and a cross edge (25) located downstream of the side edges.

  • Patent number: 5147280
    Abstract: A centrifugal separator having a device for the transformation of kinetic energy of a liquid rotating in a chamber (12) to pressure energy comprising a discharge element (17) for the discharge of liquid out of the chamber. The discharge element (17) has a surface (20) arranged to be so located in the rotating liquid body that liquid flows in a predetermined direction along and in contact with the surface (20). The discharge element (17) forms an outlet channel (19) having an inlet opening (22) located in said surface (20), and limited downstreams by a cross edge (25) from which the outlet channel (19) extends a bit essentially in said predetermined direction. An increased outlet pressure is achieved by the fact that at least two passages (27, 28) are arranged in the discharge element (17) connecting a part each of the outlet channel located at axial ends of the cross edge (25), respectively, to the chamber (12) in such a manner that liquid flows through the passages (27, 28 ).

  • Patent number: 5024648
    Abstract: The present invention concerns a centrifugal separator comprising a rotor, which forms an inlet (12) for a liquid mixture, a separation chamber (5), connected to the inlet (12), for separation of components in a liquid formed mixture and a discharge chamber (10). The discharge chamber is delimited by two axially separated end walls (12, 13) and a circumferential wall (14) extending between these and has an inlet (11, 11a) connected to the separation chamber (5), an outlet in a discharge device (17) arranged in the discharge chamber (10), and means, which together with parts of the inner surfaces of the discharge chamber (10) are arranged, during operation of the rotor, to entrain into rotation a component present in the discharge chamber (10) so that this forms a rotating liquid body. This liquid body has a radially inwards directed, essentially cylindrical, free liquid surface radially inside the circumferential wall (14).
