Definitions

  • the present invention relates to a feeding device for centrifuges in general and to a device for feeding largepieced or longitudinally-shaped fly goods of fluidity into preferably horizontally disposed centrifuges.
  • Conveyor bands are normally excluded as feeding devices, since the space conditions do not permit the incorporation thereof into this device. This applies particularly for smaller and medium machine sizes.
  • the problem during flying of curled wool resides in the reduction to still lower wetness of the wool which is soaked with weakened sulfuric acid for the purpose of cleaning and which is predehydrated to about 60-70% by means of continuously operating pressure rollers.
  • the feeding of the predehydrated curled wool, which arrives in lengths of l005(l0 mm., into centrifuges is extremely difficult with the above described conventional means, particularly if horizontally supported centrifuges are dealt with.
  • the use of horizontally disposed input tubes is to be eliminated, for the reason that the capability of flowing is missing.
  • the feeding by means of conveyor screws is likewise impossible with the screw measurements which are available, because the long wool pieces wind up about the screw shaft and about the screw threads and, thereby, a conveyance is prevented.
  • the present structure comprises a centrifuge housing 1 wherein a sieve drum 2 having a reciprocating slide bottom 3, which sieve drum 2 is rotatably mounted in the centrifuge housing 1.
  • the sieve drum 2. is surrounded by the filtrate receiving housing 4- having a filtrate outlet branch 5 and a solid goods receiving housing 6 with the corresponding outlet branch 7.
  • a feeding device 8 terminates: in the centrifuge drum and comprises a tube 9, a filling hopper 10 and a blower 11.
  • a conveyor band 12 serves the feeding of the feeding device with fly goods.
  • the operation of the centrifuge is as follows:
  • the wool pieces 13 which have been dehydrated by means of pressure rollers (not shown) are thrown off from the conveyor band 12 into the filling hopper 10 and enter, thereby, the tube 9, where they are gripped by the air stream produced in the blower 11 and are thrown toward the slide bottom 3. Due to the rotation of the slide bottom 3, the wool pieces 13 are centrifuged towards the sieve drum 2 and form therein a socalled centrifuge cake, which is advanced stepwise in the direction to the solid goods receiving housing 6 and finally thrown off into the housing 6.
  • the liquid centrifuged in the sieve drum 2 from the centrifuge cake is received, in the filtrate receiving housing 4 and fed off through the filtrate output branch 5.
  • the dehydrated wool leaves the centrifuge through the output branch 7.
  • the dehydration of the wool in the described manner is performed automatically and continuously. No attendance is required during this operation.
  • an air nozzle (not shown) is disposed at the rear end of the tube 9, which creates a sharp air stream.
  • the device designed in accordance with the present invention makes possible a safe and no service requiring feeding of large curled, longitudinally-shaped, relatively dry and voluminous fly goods.
  • curled wool In the particular case of dehydration of curled wool it creates the condition for the automatic and, thereby, economic centrifuging of this product, which could not be brought about with the conventional feeding methods.
  • a centrifuge including a device for feeding of particularly large curled, longitudinally shaped fly goods of a predetermined fluidity, comprising a centrifuge housing,
  • a sieve drum rotatably mounted in said centrifuge housing and having a reciprocating slide bottom and being open at its end opposite said slide bottom,
  • a filtrate receiving housing having a filtrate outlet branch and surrounding said sieve drum
  • a hopper communicating with said feeding tube intermediate its ends and adapted to feed fly goods of a predetermined fluidity into said feeding tube
  • a source of pressurized fluid operatively connected with the other end of said feeding tube, in order to convey said fly goods into said sieve drum.
