摘要： A feed accelerator system for use in a centrifuge, the system comprising a conveyor hub (26) rotatably mounted substantially concentrically within a rotating bowl (12), and an accelerator (43) including a cone-shaped inside surface (29) disposed between an accelerator base (31) and an accelerator small diameter section (33). The accelerator (43) is secured proximately to its base within the conveyor hub (26) so that the accelerator (43) rotates with the conveyor hub (26). A distributor including a distributor surface (37) having no sharp bends or junctions is secured to the small diameter section (33). A plurality of accelerator vanes (39) are disposed on the cone-shaped inside surface (29) and extend proximately from the small diameter section (33) and terminate at a location on the cone-shaped inside surface (29) proximate to the accelerator base (31) so that an unvaned portion of the cone-shaped inside surface forms a smoothener section (41). A feed pipe (34) having at least one discharge opening (38) is disposed within the centrifuge so that the discharge opening (38) is positioned proximately to the distributor surface (37) at a stand-off distance (D). The stand-off distance (D), feed slurry flow rate, diameter of the feed pipe (34), location of the accelerator vanes (39) proximate to the small diameter section (33), and number of vanes are selected to obtain overall maximum centrifuge efficiency.

摘要： A decanter centrifuge comprises a drum (1) with a conveyor (2) containing an inlet (4). The liquid to be separated flows in a jet centrally into the inlet (4) towards an end wall (11), at which the liquid is radially distributed and flows axially onwards towards the second end wall (13) through an area of the inlet (4) free of members imparting an angular velocity to the liquid. The inlet (4) is provided with inlet apertures (6) positioned on a radius larger than the radius to the overflow edge (9) at the liquid discharge. The design of the inlet (4) implies that the free liquid surface in the inlet during operation is drawn far towards the axis of the drum, thereby causing excess energy supplied to the liquid during acceleration to the angular velocity of the conveyor (2) to be dissipated in the comparatively thick liquid layer before the liquid discharges into the separation space (7) through the inlet apertures (6).

摘要： The decanter centrifuge has a bowl with a screw conveyor having a body (4) and a screw (7). Material to be separated into a light phase and a heavy phase is supplied through inlet ports (6) in the body, and the heavy phase is discharged through discharge ports in the bowl at one end of the conveyor. Between the inlet ports and the discharge ports for the heavy phase, the body of the screw conveyor carries a baffle (8c), generally shaped as a radial rib which forms a helical surface turning in the same direction as the screw (7). Owing to its shape the baffle actively contributes to the transport of the heavy phase, and with retention of the same gap between the baffle and the inner surface of the bowl, the gap area can be increased by increasing the axial length of the baffle.

摘要： A decanter centrifuge (1) has a rotor comprising a helical conveyor (2) and a drum (20). The conveyor (2) comprises a conveyor hub (3) and helical flights (4), and the drum comprises an inner shell (21) of steel and an outer shell (22) of fibre reinforced plastic. The conveyor (2) consists of a shaft of tube form (11), primarily made from carbon fibre reinforced resin, and helical flights (4), primarily made from polyurethane. The flights (4) of the helical conveyor are formed in such a way that all the time they are in contact with the inner periphery of the drum (31). The division of the drum in an inner and an outer shell causes the mass of the drum to be reduced considerably.

摘要： Besides a first gate (3) for discharging liquids, a centrifugal drum (1) has a second gate (6) for discharging the separated solids. An overflowing edge (8) provided for the solids is located at at least the same radial distance from the axis of the drum as an overflowing edge (5) for the liquids formed by the first gate (3). The length of the overflowing edge (5) of the first gate (3) and the length of the overflowing edge (8) of the second gate (6) have the same mutual ratio as the volume flows to be deflected over the overflowing edges. Because of the hydraulic pressure reigning in the centrifugal drum, the product streams flowing out of the centrifugal drum are subdivided, so that the desired concentration is obtained at the solid side. If the inflowing amount fluctuates, changing the level of liquid in the centrifugal drum, this change has a proportional effect at both gates (3 and 6), i.e. the ratio between the solid concentrate and the separated liquid does not change, so that the solid concentration also remains constant.
