    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 comprising a rotor which inside itself forms an inlet chamber (16), a separation chamber (5) and an outlet chamber (12). The outlet chamber (12) is connected to the separation chamber (5) via a passage (13) through which a liquid separated during operation flows into the outlet chamber (12) and in the same forms a rotating liquid body with a radially inwardly directed free liquid surface (14). The outlet chamber is provided with an outlet (19), which is located radially outside the free liquid surface (14). In the outlet chamber (12) at least two wall elements (22) are arranged fixedly connected to the rotor and arranged to form a channel between themselves in order to during operation entrain the separated liquid into the rotation of the rotor and at the same time admit flow of the same radially outwardly in the outlet chamber (12). To make an effective entrainment possible without a great risk of air admixture the wall elements (22) have a portion, which extends radially between the radial level at which the free liquid surface (14) is located and a level radially outside the outlet (19), and which has a directional component in the circumferential direction, which seen radially outwardly is directed forwardly in the rotational direction.

    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.

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).
