Definitions

  • the invention relates to a vibrating trough with fluidizing device for separating a bulk material mixture of different densities into fractions with essentially the same density, in particular for separating a combustible mixture of coal, pyrite and mountains, the vibrating trough having a gas-permeable material support (inflow floor) and a material supply and the two ends have material discharges and the heavy fraction of the bulk material is conveyed on the vibrating trough in one direction and the light fraction is fluidized and flows over the heavy fraction in the other direction.
  • Devices are also known for separating particles of different weights in a bulk material mixture and for reading out heavy admixtures from granular bulk material with vibrating troughs through which air flows (DE-DS 24 S2 523 and DE-DS 24 o4 756).
  • the object of the present invention is to further ver the separation effect of a vibrating trough with fluidizing device improve. This object is achieved by the features specified in the patent claims. The claims also contain embodiments of the invention.
  • the inventive design of the material support at the discharge end for the heavy fraction and the arrangement of at least one transverse wall in and / or in front of this area largely prevents light fluidized material from getting into the discharge area for the heavy fraction and being able to be taken away by it.
  • An improved separation effect is therefore achieved compared to the known prior art.
  • smaller cross walls are provided, which can be of different heights and / or can be arranged at different heights above the product support.
  • the transverse walls can also have different cross-sectional shapes and e.g. be angular, the angular opening pointing in the direction of flow of the light fraction.
  • the vibrating trough according to the invention can be arranged horizontally as well as an inclined vibrating trough, wherein in both cases a plurality of troughs can also be provided one behind the other.
  • the invention is shown schematically in the drawing using an exemplary embodiment and is explained in more detail in the description.
  • the drawing shows, in a highly simplified manner, a Sonrägschwingrinne with fluidizing device and the features according to the invention.
  • the inclined vibrating trough 1 has a material feed 2, an air feed box 3 with air connections 3 a for supplying the fluidizing air and a drive device 4.
  • a material feed 2 an air feed box 3 with air connections 3 a for supplying the fluidizing air
  • a drive device 4 instead of the inclined vibrating channel, one can horizontally arranged vibrating trough can be provided.
  • the elastic support of the channel, details of the air supply, the material discharge and other known details are not shown.
  • the vibrating channel 1 has a gas-permeable material support (inflow floor) 5, which is located above the air supply box 3.
  • the air supply box 3 and the gas-permeable material support 5 extend only over part of the channel. At the discharge end 6 for the heavy fraction, fluidization air does not flow through the channel.
  • transverse walls 7, 7 'and 7 are arranged above the crop support 5.
  • the cross walls are mounted in such a way that the heavy good parts can pass between the cross walls and the crop support 5, ie below the cross walls
  • the transverse walls can be of different heights and / or different heights above the good support, and can have the same or different cross-sectional shapes, but they can also be of the same design and arrangement, for example, it has proven expedient to separate a mixture from Coal, pyrite and mountains to make the gap between the transverse wall 7 ′′ and the material support 5 larger than the gap on the transverse wall 7 ′ and this in turn larger than the gap on the transverse wall 7.
  • the transverse wall 7 is of an angular shape, the angular opening pointing in the direction of flow of the light parts.
  • the transverse walls 7 'and 7 "are designed as flat baffles of different heights, which are attached perpendicular to the material support 5 or the conveying direction.
  • the baffle plates can also be arranged obliquely to the material support.
  • transverse walls instead of three cross walls, as shown in the figure, a different number of transverse walls can also be provided. It is also possible to arrange only a single transverse wall in or in front of the gas-impermeable end region 6 of the vibrating channel 1.
  • baffles 8 and 9 are provided, which accumulate the heavy fraction (on the baffle 8) or the fluidized light good parts (on the baffle 9) before they are discharged from the channel, so that congestion zones arise here.
  • the baffle plates can be arranged at different heights and fixed or their height can be adjusted. This makes it possible to adapt the vibrating trough to non-harmful materials. It is also possible to arrange the baffle plates 8, 9 inclined in the conveying direction, so that the material to be conveyed can slide onto the baffle plates.
  • the material passing through the material supply 2 onto the material support 5 of the sliding channel 1 is separated into a heavy and a light fraction by the oscillating movements of the channel and the simultaneous supply of fluidizing air.
  • the heavy portions of good decrease due to the interaction of vibrating or Conveying movement and fluidization on the product support 5.
  • the light material portions are fluidized and form a layer above the heavy fraction, which behaves approximately like a liquid and glides on the heavy material portions as far as to the end of discharge at the Staupoeon 9.
  • the transverse walls 7, 7 'and 7 “have the effect that the fluidized material layer cannot spread towards the discharge end for the heavy fraction.
  • Light parts of the heavy material parts are initially carried along by the material supply
  • the conveying movement of the heavy parts is fluidized and prevented by the transverse walls 7, 7 ', 7 "from spreading in the direction of the discharge end 6 for the heavy fraction. Compression zones can form between the transverse walls.
  • the fluidized light material parts can flow over the transverse walls to the discharge end for the light fraction.
