| abstract | 711,320. Centrifugal separators. HERCULES POWDER CO. Aug. 5, 1952 [Nov. 27, 1951], No. 19704/52. Class 23 A strainer separator comprises a basket having a perforated side wall 7 and an imperforate base 6 having a socket member 3, a drive shaft 1 engaging the socket, and a solids discharging piston 8 positioned above the base and actuated by the centrifugal pressure of a fluid supplied to the space between the piston and the base. To ensure rotation of the piston with the basket. indentations in the underside of the piston are loosely engaged by projections 6A on the basket bottom. The piston is raised so that its hub 5 just engages a stop 4 by fluid supplied by a pipe 14, tubular extension 10 fixed to the piston and passages 50 to the space between the piston and base. The piston is lowered by withdrawal of the fluid below the piston through valves 37 and ports 38 in the basket wall. Slurry to be treated is fed into a can, Fig. 11 (not shown), having an arcuate outlet projecting into the annular space between a fixed baffle 25 and a baffle 11 fixed to the piston, and flows between the baffles to the basket.' In a modification, Fig 12 (not shown), both the baffles are fixed to the piston. Wash-liquid pipes 17 .... 22 of different lengths depend into the basket to discharge at levels corresponding to the inlets of liquid-collecting chambers formed by annular partitions 27....32, liquid from the pipe 17 collecting in the inner chamber. Connected vent pipes 15, 13 are provided for the removal of fumes from the casing 26, and compressed air is supplied by a duct 2 to the housing for the drive mechanism to prevent corrosive action of fumes. The screen is formed by perforations 42 in the basket wall and spaced vertical bars 44 attached to the wall by rings 45. A measured quantity nitrocellulose and spent acid slurry is fed to the basket with the piston in its lowermost position as shown. After the acid has been extracted and a mat of nitrocellulose formed on the lower parts of the basket side wall, the piston is raised by the supply of a measured quantity of fluid (spent acid) through the pipe 14. The fluid escapes through the ports and valves and as the piston sinks a second quantity of slurry is supplied to the basket and the mat which has moved up the basket wall is washed with dilute acid from the wash-liquid pipe 17. The cycle of slurry supply and piston reciprocation continues and the mat is finally discharged over the edge of the basket wall to the container between the casing 26 and the partition 27. The dilution of the acid discharged from the wash pipes increases with the increase in level at which the pipe discharges so that the mat is finally washed with water. Dimensions and speeds of a separator suitable for the treatment of nitrocellulose are given in the Specification. |
