摘要： The invention relates to a decanter centrifuge comprising a scroll conveyor rotatable around a preferably horizontal axis of rotation mounted substantially concentrically within a rotating bowl (1), the scroll conveyor comprising a hub (8) and at least one helical winding, the hub (8) including an inside surface and an outside surface, at least one passageway between the inside surface and the outside surface of the scroll conveyor, a feed pipe (3) in the center of the scroll hub (8). It is characterized in a number of nozzles (10) provided extending from the inside of the feed chamber (4) to the outside wherein on the inside surface of the scroll hub (8) and between the nozzles (10) around the circumference there are provided accelerator inserts (16). The invention also relates to a feed chamber (4) for such a decanter centrifuge. This invention results in a new feed chamber for the scroll with high efficiency, smooth product acceleration, wear protection and easy maintenance.

摘要： The invention relates to a solid bowl centrifuge with a horizontal elongated, hollow, rotatable, solid-wall bowl (2) with an inlet and an outlet and a rotatable screw conveyor (5) with a shaft and helical screw (7) rotatable mounted inside said bowl and extending substantially the full length thereof. It is mainly characterized in that on the shaft there are mounted a number of truncated conical discs (24), whereby the discs (24) are surrounded by the helical screw (7). With such design the decanter capacity can be increased and the polymer consumption reduced. Further power consumption can be reduced by obtaining the same performances as the traditional decanter at lower rotational speed (lower g-force).

摘要： The invention relates to a decanter centrifuge with a rotating bowl (1) provided with at least one solids discharge port and at least one clarified liquid discharge port and a screw conveyor (2) disposed coaxially within said rotating bowl (1) rotated in the same direction with a differential rotational speed, where a feed suspension to be separated is introduced into a ring shaped space formed between said rotating bowl (1) and said screw conveyor (2) through a central feed pipe (10) fixed to the end of the screw conveyor (2) and supported in at least one bearing (16) and can be separated by centrifugal force into a solid and a liquid phase so that said solid phase is discharged from said solid discharge port and said liquid phase is discharged from said clarified liquid discharging apparatus (5). According to the present invention it is characterized by a liquid phase conduit (4) arranged in the hollow shaft of the rotating bowl (1) guiding the liquid phase outside of the bearings, a liquid phase discharge valve provided outside the bearing (16; 18) on the side facing away from the bowl (1) and screw (2) and a sealing at the end of the feed pipe (10) surrounded by the liquid phase conduit (4). So it is possible to pressurise the system and to use the pressure from the feed pump to support the cake transport in the solids transporting part of the bowl, thereby eliminating the need for variable speed conveyor control and equipment.
