Definitions

  • This invention relates to a centrifuging device, particularly adapted for high outputs, for separating the liquid from the solid matter of material to be centrifuged.
  • centrifuging unit which is suitable for the highest centrifuging outputs, is simple in construction and permits of careful centrifuging.
  • the screening surface of the device is subdivided into a number of small-diameter foraminous separator cages, through which the centrifuged material flows in parallel.
  • centrifuging output of the unit can also be increased as desired by increasing the number of small-diameter individual cages, and during operation, the existing requirements can be easily met by switching individual cages off and on, without impairing the quality of the centrifuging process.
  • FIG. 1 shows an axial vertical section on the line I-I of FIG. 2 through a centrifuging device
  • FIG. 2 shows a section on the line IIII of FIG. 1;
  • FIG. 3 shows an axial vertical section on the line IIIIII of FIG. 4 of another embodiment
  • FIG. 4 shows a section on the line IVIV of FIG. 3.
  • the centrifuging device shown in FIGS. 1 and 2 has in a housing 1 seven small-diameter foraminous separator cages 2, among which the screening surface of the device is divided.
  • the centrifuged material passes through these separator cages 2 in parallel.
  • the cages are carried in each case by a shaft 3, to which an armature 4 of a motor 5 is secured, and which are journalled in bearings 6 and 7 in the housing 1.
  • Each separator cage has an inlet end with a hopper 8 and a pusher-member 9, which is reciprocated in the axial direction of the separator cage 2 by a servomotor 10 mounted in the shaft 3.
  • the servomotor 10 is supplied with oil under pressure from a source of pressure oil, not shown, comprising a motor and oil pump.
  • Each separator cage is provided with its own centrifuged material supply pipe or branch 11 connected via a proportioning or shut-off device 12 to a ice distributor pipe 13.
  • Each individual cage may be regulated separately, for example by throttling or increasing the supply of material to be centrifuged when the power absorbed by the motor differs from a predetermined value.
  • the rotors consisting of separator cage 2, shaft 3, armature 4, pusher mechanism 9 and servomotor 10 are adapted to be removed from and inserted intq the housing 1 individually.
  • a stationary annular trough 14 is provided round each outlet end, which trough collects the centrifuged solid matter and leads it through an orifice 15 in the bed of the trough in a compact, di-
  • separator cages 18 are journalled in honeycomb arrangement in a housing 19.
  • the outlet ends of the superimposed cages project somewhat beyond the outlet ends of the underlying cages, so that the stream of solid matter issuing from the annular troughs can pass unimpeded onto a conveyor belt 20.
  • the small-diameter separator cages may also be constructed in two-stage or multi-stage fashion.
  • the cages and their pusher mechanisms may also be driven by a common motor.
  • a centrifuging device for separating the liquid from the solids of a material being centrifuged comprising:
  • drums being differently spaced from the collecting means and the outlet end of any drum projecting axially beyond the outlet end of any other drum lying closer to the collecting means.
