Abstract

An improved centrifuge having a clutch mechanism (120) with a shifting coupling (122) which provides a positive lock for synchronous blade (170) and bowl (185) rotation during processing.
The scraper blades (310, 320, 330, 340) have recesses (314, 324, 334, 344) for inserts (315, 316, 325, 326, 335, 336, 345, 346) permitting a variable cutting edge geometry and the mixing and matching of cutting edge geometry while using the same base blade (300). The centrifuge has a tangential outlet (507) and an annular housing (502) to minimize spray and misting in the exiting centrifuged liquid. The centrifuge has a plurality of blades (610, 620, 630, 640, 710, 720) with radially overlapping edges (614, 624, 534, 644, 714, 724) to keep the fluid being centrifuged compartmentalized and thus quiet for maximum efficiency. The scraping assembly blades (610, 620, 630, 640) are angled (617, 627, 637, 647) in the scraping direction to force the solids towards the exit of the centrifuge. A
programmable logic controller monitors the load on the drive motor (207) to determine flow rate of injected fluid and/or to ascertain whether any dysfunction is occurring and to take appropriate steps to correct malfunction.
