Abstract

574,667. Centrifugal separators. AKTIEBOLAGET SEPARATOR. May 19, 1944, No. 9661. Convention date, July 13, 1943. [Class 23] The discharging of sludge from a bowl 1 of a separator, through outlet ports 18, is controlled by a servo piston 13 having a through hole 15 which lines up with 18 when discharging is required. Servo fluid is supplied by pipes 23, 24 to the lower or upper end of the piston when movement is required. Each piston chamber 9 is provided with a liner 11. Servo fluid drain holes 27, 28 are positioned as shown.. A packing member 17 bears on a flat surface 14 of each piston. Fig. 3 shows a modified arrangement in which the opening interval of the port 18 is short to prevent liquid escaping with the sludge, the port 8 and hole 15 lining up only when the piston is passing. The packing is of soft material and may have a sleeve 29 of metal, synthetic resin or other material. To prevent sludge particles from getting between the slide and the packing, the sleeve has sharp edges. The packing 17 may be in the form of a metal bellows to which packing material is vulcanized or otherwise fixed. The packing may be a plane elastic disc. Servo fluid may be supplied to one end only of a piston, a spring returning the piston when the pressure on the fluid is released.
