Centrifugal separator having an elastic connection

摘要

In a centrifugal separator having a stationary part, a non-rotating part, is elastically connected to the stationary part, and a rotating part, rotates around an axis of rotation and includes a centrifuge rotor and a rotating bearing-receiving element. The centrifuge rotor includes a disk package with a plurality of separating disks. The rotating part is journalled in the non-rotating part so that the rotating part and the non-rotating part are commonly pivotable relative to the stationary part. A drive arrangement drives the rotating part about the axis of rotation within a range of revolutions. An inlet channel extends into the inner separation space for feeding of a medium to be separated. An outlet channel extends out from the inner separation space for discharge of a separated product. The bearing-receiving element is tubular. At least one of the inlet channel and the outlet channel extends through the bearing-receiving element.

1. A centrifugal separator comprising:
a stationary part forming a base configured to be located on a ground; a non-rotating part, which is elastically connected to the stationary part by means of an elastic connection, and which comprises a carrying element; a rotating part, which is configured to rotate around an axis of rotation and comprises a centrifuge rotor, which comprises a rotor casing forming an inner separation space, and a rotating bearing-receiving element configured to receive a bearing arrangement, wherein the centrifuge rotor comprises a disk package having a plurality of separating disks and wherein the rotating part is journaled in a stiff manner in the non-rotating part in such a way that the rotating part and the non-rotating part form a common pivot unit that is in pivotable communication with the stationary part by means of the elastic connection; a drive arrangement for driving the rotating part to rotate around the axis of rotation within a range of revolutions, which is from zero to a highest number of revolutions per minute and which comprises at least an operating number of revolutions, the drive arrangement comprising a power transmission element, the power transmission element being in engagement with a drive wheel, the drive wheel comprising and being provided on the rotating part, and arranged to transmit a drive force from an electric motor to the drive wheel; an inlet channel, which extends into the inner separation space for feeding of a medium to be separated; at least an outlet channel, which extends out from the inner separation space for discharge of a separated product; the bearing-receiving element being tubular and at least one of the inlet channel and the outlet channel extends through the bearing-receiving element, wherein the bearing-receiving element is connected to an outwardly projecting part proximate an upper end thereof on which the disk package is provided and to which the rotor casing is connected; and the bearing arrangement is comprised by the rotating part and the non-rotating part and which further comprises a first bearing and a second bearing both provided between and connected to the bearing-receiving element and the carrying element, wherein the drive wheel is provided on the bearing-receiving element axially between the first bearing and the second bearing.
