Definitions

  • the present invention relates to a feed distribution and control arrangement for centrifugal separating machines.
  • the invention relates to centrifuges for the separation of solid and liquid mixtures one example of which is massecuite.
  • Massecuite is a mixture of solid sugar crystals and molasses.
  • the distribution of the solid/liquid mixture to the conically shaped rotating basket is important to the proper separation of the solid particles from the liquid carrier.
  • the present invention seeks at least to overcome these disadvantages in the prior art.
  • the present invention improves on prior art arrangements by providing for centrifugal separating machines a stationary feed distribution and control device to deliver the solid/liquid mixture to the centrifuge.
  • a feed distribution and control arrangement for a centrifugal separating machine having a centrifuge basket including a vertical central stationary member having a cylindrical extension joined to a co-axial frusto-conical member, and a co-axial outer sleeve member enclosing said central member to define therebetween a variable annular space for receiving a liquid/solid mixture, said outer sleeve being movable vertically to thereby vary the opening or closing of said annular space to control the flow rate of said mixture and the distribution thereof into a lower part of the centrifuge basket of said centrifugal separating machine.
  • Figure 1 shows a broad schematic cross section of the apparatus according to the invention
  • Figure 2 shows an enlarged schematic of the area corresponding to the feed zone of the centrifuge.
  • a rotating basket or drum 10 which is driven from below comprises a frusto-conical member 12 joined to a central cylindrical section 40 which houses drive shaft and bearings (not shown) .
  • the basket 10 is perforated to allow escape of the liquid component of the mixture into chamber 20 while solids, for example, sugar crystals in a massecuite, move up the basket 10 and thence into chamber 30.
  • a cylindrical sleeve member 100 is arranged co- axially about cylindrical section 40 of the drum 10.
  • Sleeve member 100 surrounds a central stationary conical member 60 fixed to a cylindrical extension 70 supported against the wall of bent tube 90 by radial webs 80. The mixture of liquid and solid is fed along tube 90 leading to sleeve 100 as indicated generally at arrow 85.
  • the feed material may then be introduced into the head box by a branch pipe of about the same diameter as tube 90 in any convenient location and at any convenient angle.
  • the cylindrical extension 70 may continue through the top of the head box in a manner similar to Figure 1 or may be terminated inside tube 90 or the head box by a suitable closure, for example near the top of radial webs 80.
  • Sleeve member 100 is movable vertically along the axis of the sleeve to define a loading or distribution region 50 for the centrifuge.
  • Sleeve member 100 is of a diameter such that when it is completely lowered it closes the annular gap 120 between its lower edge and conical member 60.
  • Suitable mechanical means 110 are provided to control movement of the sleeve member 100.
  • Means 110 may be either operated manually or automatically.
  • the annular gap 120 can be adjusted to control the rate of flow of solid/liquid feed mixture while also enabling it to be distributed in a uniform curtain 130 on to the rotating distribution region 50 of basket 10.
  • Extension 70 may comprise a hollow column connected to cone 60 to be used for the introduction of steam, water, molasses, syrup or other fluids into the lower distribution area 50 for the purpose of heating or lubrication. Equally the inner surface of the feed material within sleeve member 100 can be heated or lubricated through the extension 70 and cone 60.
  • extension 70 does not continue through the bend in pipe 90 or through the alternate head box, convenient connections may be made to extension 70 or cone 60 by pipes attached to or incorporated in the webs 80 and penetrating the wall of pipe 90 at convenient locations.above sleeve 100.
  • spray nozzles for steam, water, molasses, syrup or other fluids can be mounted on the outside of the sleeve member 100 to treat the material on the basket of the centrifuge.
  • the present invention provides a simple and effective arrangement for the distribution and also the control of the feed mixture in a centrifugal separating machine. Though the invention has been described above with respect to a driving arrangement in which the conical basket is driven from below with the discharge of the separated components occurring vertically other arrangements are possible within the knowledge of a person skilled in the art. Equally it is to be understood that the arrangement can be used with other solid/liquid mixtures than massecuite and with other basket or drum shapes.

Abstract

Un tube (100) alimente en un mélange solide/liquide (130) le centre d'un bol perforé rotatif (10) d'un séparateur centrifuge, qui comprend une partie centrale cylindrique (40). On régule l'alimentation en déplaçant le tube (100) verticalement de sorte qu'un espace annulaire (120) est produit dans la région (50) située entre l'extrémité conique (60) et le tube (100). L'élément central comprenant l'extrémité (60) à laquelle est fixé un prolongement cylindrique (sans numéro) est immobile. Le tube (100) présente un diamètre tel que, lorsqu'il est complètement abaissé, il ferme l'espace (120). L'élément et l'extrémité (60) peuvent être creux afin de permettre l'introduction, dans la région (50) de vapeur, d'eau ou d'autres fluides destinés au chauffage ou à la lubrification. L'invention se rapporte particulièrement à la centrifugation de la masse cuite.
