Definitions

  • the invention relates to a continuously operating centrifuge, in particular a sugar centrifuge, with a centrifuge basket, a feed tube for the filling compound extending into the basket and an accelerator and heating device arranged at the bottom of the basket, which coaxially to the basket has rings of different diameters arranged concentrically one inside the other, the inner wall of which is arranged expanded conically downwards and the filling compound is thrown to the outer ring in front of its lower horizontal edge.
  • Such a centrifuge is known from DE-OS 23 28 830.
  • the accelerator device arranged there at the bottom of the centrifuge basket has rings which are alternately fastened to the bottom and to an upper ring plate and which are triangular in cross section and which produce a maximum of four flight paths for the filling compound. It is also from DE-OS 28 41 725 known to provide an accelerator device with conical, coaxial surfaces made of sheet metal, which generate two flight paths.
  • the object of the invention is to improve a centrifuge of the type mentioned in such a way that considerably more flight paths are generated in the narrowest space within the acceleration and heating device than was previously possible, and to supply the steam so that it is free flying filler comes into contact on all flight routes.
  • Flight routes are of great importance for the effectiveness of the heating device.
  • the filling compound forms a very thin, free-flying layer on these lines, which offers a large surface area for the steam.
  • the heat transfer is therefore very effective, and the more effective, the more flight routes are available.
  • the construction according to the invention enables the number of flight paths to be generated approximately twice as much as the number of rings. This makes it possible to generate many flight paths of the filling compound or filling compound curtain in a very narrow space.
  • the device is of the simplest construction. A very even application of the filling compound onto the basket is achieved and the filling compound is intimately mixed with water. Through the rings open at the top, water vapor can be brought into the interstices of the rings and thus into the flight paths in a structurally simple manner, so that optimal heat transfer to the filling compound is achieved. Furthermore, the interspaces between the rings which are open towards the top create the security that if there is a jam of filling compound inside the accelerator device, it can easily escape upwards.
  • a safe transfer of the filling mass through flight routes in the lower area of the rings is created in that the ring lying further outwards projects with its horizontal free lower edge deeper into the basket than the free lower edge of the ring lying further inside.
  • a transfer in the upper area is achieved in that the horizontal free upper edge of the outer ring is higher than the free upper edge of the further inner ring.
  • a structurally simple construction with small dimensions and low weight is achieved in that the rings are formed by conically bent sheet metal strips.
  • the height of the rings can increase from the inside to the outside.
  • the rings are attached to one another in the central region.
  • the fastening parts are located in an area in which they interfere very little with the even flow of the filling compound.
  • radial rods penetrate the rings for fastening them.
  • Optimal attachment of the rings to the basket base is achieved in that the innermost ring is carried by a hollow, coaxial support cone that widens conically upwards, which is attached to the bottom of the basket, is surrounded by the innermost ring and has at least three openings in its wall. This also makes the filling compound more uniform. It is also proposed here that the openings have a greater length than height and extend horizontally in their length.
  • a circular horizontal plate is attached coaxially to the basket bottom.
  • This centrifuge can be used particularly advantageously for processing highly viscous filling compound.
  • the continuously operating sugar centrifuge has a conically expanding centrifuge basket 1 which rotates about a vertical axis.
  • a feed tube 2 projects coaxially into the basket 1 from above, through which the filling mass flows centrally into an accelerator device 3 which is fastened to the bottom 4 of the basket.
  • the accelerator device 3 has rings 5 made of sheet steel, which have a circular cross section, coaxial to the axis of rotation of the basket 1 are arranged and taper conically towards the top.
  • the inner walls of the rings 5 are parallel to one another, so that the rings form annular spaces 6 between them, the walls of which form an angle of approximately 6 degrees with the vertical.
  • the annular spaces 6 are open at the top and bottom.
  • the height of the rings 5 increases steadily towards the outside, the upper free horizontal edges of the rings 5b-5e being higher from ring to ring and likewise the lowest horizontal edges of the rings from ring
  • the ring is lower towards the outside, so that the rings gradually increase in height at the top and bottom.
  • Only the innermost ring 5a has a higher upper edge than the second ring 5b, to which a horizontal fastening ring is welded, which is supported by the upper ends of vertical rods 8, which are arranged eccentrically in a circle parallel to the axis and stand on the bottom 4 or screwed into a plate 9 standing on the floor.
  • the rings 5b-5e lying further out are fastened by radial rods 10 which are arranged approximately centrally between the upper and lower edge of the rings 5 and penetrate the rings 5b-5d.
  • the filling compound flows down through the feed pipe 2 without normally touching the walls of the pipe 2 and reaches the accelerator device 3 through the central opening of the fastening ring 7. There it meets a circular, coaxial, horizontal plate 11 of a coaxial table, which is screwed to the plate 9 with its base 12. Due to the plate 11 rotating with the basket 1, the filling material jet is deflected horizontally on all sides and strikes the inside of the innermost ring 5a. Since this widens conically downwards, the filling compound is driven downwards and reaches the lower horizontal edge of the ring 5a, from which it is thrown off horizontally in a veil until it hits the inner wall of the ring 5b. The filling compound thus travels freely through the innermost annular space 6a and water vapor flows through it, which is introduced into the spaces 6 from above through a steam feed pipe 13. This steam feed pipe is located on the side of the filler feed pipe 2.
  • the filling compound that strikes the inner wall of the ring 5b is conveyed not only downwards to the lower horizontal edge of the ring 5b, but also, from a certain quantity of filling compound, to the upper free horizontal edge of the ring 5b due to its conicity.
  • filling compound is released as a veil onto the ring 5c, and from this in the same way onto the ring 5d, and finally from this onto the ring 5e.
  • the rings 5b-5d thus form six veils or flight paths.
  • the filling mass curtain is penetrated by steam on each of these flight routes.
  • the now evenly distributed filler flies onto the side wall of the pot-shaped bottom of the basket 1, which widens conically upwards, and from there onto the sieve 14 of the basket 1 lying inside a line 15 having a plurality of outlet openings is sprayed with cold or warm water on the filling compound.
  • FIG. 3 differs of the one according to FIGS. 1 and 2 in that the innermost ring 5a is not fastened to the bottom 4 by rods 8, but by a hollow support cone made of bent metal sheet that widens conically upwards and has openings 16 in two horizontal rows one above the other Length L in the horizontal direction is greater than its height H.
  • the openings 16 are rounded on their narrow sides, and the lower horizontal edge of the openings 16 in the upper row lies approximately at the top of the plate 11.
