FIELD: machine building.SUBSTANCE: centrifugal separator comprises a rotating body which rotates in the rotation direction around the rotation axis when in work, the rotating body comprises a drum having a base provided on the rear long end of the drum, the said base is turned to the first rear long zone of the centrifugal separator behind the said base. The separator comprises at least two output channels passing through the said base, the output channels are communicated with the respective overflow edges at the respective levels, in the course of operation the overflow edges specify the level of liquid in the drum and the level of interface between two liquid phases in the drum. The first of the output channels pass axially to the first output hole providing for discharge of liquid from the rotating body into the first rear long zone in the course of operation; the second of the output channels comprises a passage leading to the second output hole providing for discharge of liquid from the rotating body into the second rear long zone set behind the first rear long zone, in the course of operation. The second output hole is provided so that its distal edge in respect to the rotation axis is placed not over the level of an overflow edge communicating with the second output hole. The separator comprises a rotating body part of shaft type passing coaxially to the rotation axis from the base; the shaft-type part supports a flange, and the above passage passes from the base via the flange to the second output hole, the flange divides the first and the second rear long zones, as well as a casing for the rotating body to be placed in, the casing comprises a proximal chamber for the liquid discharged from the rotating body through the first output hole and a distal chamber for the liquid discharged from the rotating body through the second output hole, the said chambers are separated by a partition wall. The casing including the partition wall is divided into at least two parts comprising a cover, the flange is embraced by an annular seal, the partition wall interacts with the annular seal at least when the cover is closed.EFFECT: reduced power consumption by the centrifugal separator due to the removal of heavy and light phases from the rotating body at relatively small radius or distance from the rotation axis.10 cl, 15 dwg |
