摘要： A scraper assembly (32) for removing the collected solids component (50) of a feed material from an interior wall surface (28) of a centrifugal separator bowl (18) comprises a supporting shaft (34) positioned within the bowl (18) along a vertically disposed longitudinal axis. The supporting shaft (34) is pivotal between a stowed position and an operational position. At least two longitudinally spaced scraper blades (36) are attached to the supporting shaft (34) along the longitudinal axis and are adapted to contact the solids component (50) when the support shaft (34) is in the operational position. An upper scraper blade (36) is angularly offset with respect to the lower scraper blade (36) along the longitudinal axis so that any collected solids component (50) removed by the upper scraper blade (36) may freely drop clear of the lower scraper blade (36).

摘要： A centrifugal separator comprises a bowl (200) rotatable about a vertically disposed axis including a feed cone assembly located at the closed conical lower end having a conical outer wall (212) and a cusp-shaped hub (214). An annular channel (216) is located between the conical outer wall (212) and the hub (214). A feed pipe (218) includes a feed outlet (224) which fits within the annular channel (216). In another embodiment, the bowl (100) includes an open lower end (102) and a closed upper end (104). An inverted feed cone (108) is positioned at the upper end (104) and includes a rounded cusp-shaped diverter (122) and an annular channel (132). A feed pipe (134) includes a feed applicator (138) which is positioned coaxially with an adjacent to the cusp-shaped diverter (122). The feed applicator (138) is sized and shaped to closely follow the contours of the cusp-shaped diverter (122). A vacuum (180) within a predetermined range is applied within the bowl to reduce power consumption and foaming.

摘要： Separation performance in sedimenting centrifuges, particularly generally cylindrical sedimenting centrifuges, and most particularly imperforate basket centrifuges, is controlled and enhanced by identifying a level of mixing that will produce improved separation performance and then varying the bowl-to-feed temperature differential and/or the centrifuge design to produce a desired level and type of mixing while reducing the tendency toward undesirable type of flow.
