CENTRIFUGAL SEPARATOR WITH A DISCHARGE DEVICE

摘要

A centrifugal separator comprising a rotor forming an inlet (12), a separation chamber (5) 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) is arranged in the discharge chamber (10). In the discharge chamber (10) there is arranged means to entrain into rotation a component present in the discharge chamber (10) so that this forms a rotating liquid body having a radially inwards directed, free liquid surface. In order to gently entrain the component present in the discharge chamber (10) and make a discharge possible out of it with a small degree of air admixing, the entraining means comprises at least one annular disc (19, 19a, 19b, 19c) which is fixedly connected to the rotor and has at least one part extending radially outside the level of the free liquid surface but radially inside the level of the outermost part of the discharge device (17).
