The present disclosure relates to a centrifugal separator (), which comprises a rotatable drum () having a wall (), an annular chamber () defined along the longitudinal axis () of the rotatable drum () in a portion adjoining to the wall (), wherein a mixture of substances in the liquid phase and in the solid phase is movable longitudinally through the annular chamber (), and a discharging station () for discharging the solid phase. The discharging station () comprises a vibrating unit () for agitating the solid phase. The vibrating unit () comprises a half-drum () and a vibrating device () adapted to vibrate the half-drum ().

Centrifugal separator having at least a vibrating unit and one or more drum shock absorbers

The present disclosure relates to a centrifugal separator (), which comprises a rotatable drum () having a wall (), an annular chamber (), defined along the longitudinal axis () of the rotatable drum () and bordering the wall (), an annular screw feeder () accommodated rotatably in the annular chamber () for moving a mixture of substances in the liquid phase and in the solid phase longitudinally through the annular chamber (), and separation nets () arranged in the wall () of the rotatable drum (). The separation nets () have meshes for filtering the solid phase from the liquid phase by rotation of the drum (). The separation nets () are movable relative to the wall ().

Centrifugal separator having one or more movable separation nets and at least one adjusting member for positioning said nets

A centrifuge, including: a flange closing off one axial end of a separation chamber; a plurality of apertures that traverse axially through the flange at a radial distance from a flange axis, wherein at least one aperture is in fluid communication with a first outlet passage; a plurality of weir inserts removably disposed within the plurality of apertures to control a flow of one or more fluids from the separation chamber; wherein at least one weir insert disposed within the at least one aperture in fluid communication with the first outlet passage is changeable to prevent or allow fluid communication between the separation chamber and the first outlet passage.

Centrifuge and changeable weir inserts therefor

A dual feed centrifuge system for separating solids from fluids in a drilling mud, the centrifuge system including: a bowl; a screw conveyor rotatably mounted within the bowl; a first feed pipe mounted within the screw conveyor for feeding a drilling mud through a first feed port in a wall of the screw conveyor to a first annular space between the bowl and the wall of the screw conveyor; and a second feed pipe mounted within the screw conveyor for feeding a drilling mud through a second feed port in the wall of the screw conveyor to a second annular space between the bowl and the wall of the screw conveyor. The multiple feed ports may allow the centrifuge to operate more efficiently with both weighted and unweighted drilling fluids.
