Abstract
513,827. Centrifugal separators. AMERICAN CENTRIFUGAL CORPORATION. Jan. 6, 1938, No. 424. Void. Convention date, Jan. 6, 1937. [Class 23] Centrifuges 4 are used to separate moisture from sewage sludge or the like, the separation being carried to such a point that the combustion of the solids in the furnace 6 will enable power to be supplied to the driving motors of the centrifuges. Electric motors 13, 14 for high and low speed operation are provided for each centrifuge, and when the solids are dislodged during the slow speed operation they fall on to the conveyer 5 and pass to the furnace 6. Steam generated by the device 7 passes to the receiver 8 and to the turbine or other motor 11, which is coupled to the electric generator 12. This supplies current to the various motors 13, 14 through switches 17, 18. In a modification the generator 12 supplies current to a single motor, to the shaft of which high and low speed connections for each centrifuge are made by clutches. In a further modification a single driving shaft is rotated by a steam-actuated motor receiving its supply directly from the receiver 8.
