Definitions

  • the invention relates to a method for covering the sugar in a centrifuge, preferably a continuous centrifuge, being used to clean up the sugar on the inside wall a layer of sugar in the centrifuge drum, preferably water is sprayed.
  • the invention further relates to a device for performing this method, with a connectable to a water supply Nozzle block, over the nozzles of which water is on the inner wall the sugar layer located in the centrifuge drum can be sprayed is.
  • the invention is based on the knowledge that the drum stray liquid mist due to the rotation of the drum is carried away and thereby gets into the sugar room, where it with the dry sugar separated in the centrifuge mixed. This will raise the residual sugar levels, which tends to clump together. This will further Processing of the sugar is difficult.
  • the invention is therefore based on the object Improve sugar processing.
  • this is Object achieved according to the invention in that of the sugar layer liquid mist not absorbed, reflected by it vacuumed in the immediate vicinity of the spray area and is discharged to the outside of the drum interior.
  • the above-mentioned object is achieved according to the invention by a Suction device arranged adjacent to the nozzle spray area for that which is not absorbed by the sugar layer but is reflected Liquid mist.
  • the suction of the liquid mist can procedurally z. B. on the principle of an ejector nozzle.
  • a suction nozzle is mounted, preferably - Based on the direction of travel of the sugar on the inside of the drum - Above and opposite the nozzles Direction of rotation of the centrifuge drum slightly offset.
  • the suction mouthpiece can a hose connected to a suction blower or a vacuum pump be.
  • this can Suction nozzle can also be part of a steam jet pump.
  • the drawing shows a vertical section through the right Part of a centrifuge drum 1 with a vertical axis of rotation.
  • a sugar layer 2 travels on the inner wall of this drum under the influence of those resulting from the rotation of the drum Centrifugal forces from the drum bottom up to the discharge edge 3, over which the cleaned sugar is thrown off.
  • a cover device is provided to clean the sugar, which in the illustrated embodiment one to one Can not be connected to the water supply connectable nozzle stock 4, which is equipped with nozzles 5 and arranged stationary is, protrudes into the interior of the centrifuge drum 1 and at least approximately parallel to the conical wall of the centrifuge drum 1 lies. Via the nozzles 5 water is on the sprayed upward migrating sugar layer 2.
  • a suction nozzle 6 is mounted, the above of the nozzles 5 and these opposite in the direction of rotation Centrifuge drum 1 arranged somewhat offset and over a flexible hose 7 connected to a suction blower 8 is.
