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