    摘要: In a centrifugal rotor there is an inlet chamber (7), a separation chamber (8) and an outlet chamber (10), which chambers are coupled in series. A stationary outlet member (16) is arranged to remove from a predetermined level in the outlet chamber (10) separated liquid during normal operation of the centrifugal rotor. For internal cleaning of the centrifugal rotor there is arranged within the outlet chamber (10) inside said predetermined radial level a preferably stationary reconducting member (26) that is dimensioned to accomplish a recirculation flow of cleaning liquid through said chambers (7, 8, 10) in the centrifugal rotor, which circulation flow is substantially larger than the flow of liquid which during normal operation of the centrifugal rotor passes through these chambers.

    摘要: A centrifugal separator to clean a liquid from a substance having a lower density than the liquid comprises a rotor forming a separation chamber (6), in which a stack of conical separation discs (15) is arranged. Liquid and substance dispersed therein flow radially outwards in interspaces between the discs. To increase the separation capability upon a high flow through the separator, the separation discs (15) have a radial inner zone (29a), which has no obstacles for primary flow in the circumferential direction and a radial outer zone (28a), which has so many equally around the rotational axis distributed elongated and through the outer zone (28a) extending obstacles (27a) for liquid flow in circumferential direction that the primary flow in this zone (28a) takes place radially outwards between the obstacles (27a). The obstacles (27a) have such a length and such a direction in relation to the primary flow that the liquid flow in a layer closest to a layer of substance so influences the layer of substance that separated substance is accumulated on and flows radially inwards along the flow obstacle (27a) ahead.

    摘要: In order to free a liquid form a substance dispersed therein and having a larger density than the liquid a centrifuge rotor is used having a stack of conical separation discs. Elongated spacing members (11a, 11b) in the spaces between the separation discs are formed such that the liquid flow in the disc interspaces is conducted in a certain way. Thus, the main part of the liquid is conducted in flow paths (12a, 12b), each of which has a direction with one radial component and one component turned against the rotational direction of the rotor.

    摘要: 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. To make the energy transformation more efficient the opposite side edges (23, 24) of the inlet opening (22) diverge in said flow direction along a part of an extension of the side edges and at least one of the side edges has such a direction that liquid crossing the same flows into the inlet opening (22).

    摘要: 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 ).
