Definitions

  • the invention relates to a gravity separator.
  • Gravity separators are classification machines from the class of current classifiers. Gravity separators have "uniaxial or one-dimensional" flow fields. This applies both to so-called climbing sifters and to horizon viewers.
  • the residual materials include, for example, mixed scrap, as obtained in the treatment of end-of-life vehicles.
  • Mixed scrap contains, for example, metal parts, but also plastic parts such as upholstery of car seats etc.
  • the invention is based on the object to offer a gravity separator of the type mentioned, in which as little external air passes in the material supply in the classifying, so as to improve the separation sharpness of the material to be classified.
  • the aim of the invention is thus to make the closure unit so that on the one hand possible continuously rests on the material flow or is guided over this and on the other hand to achieve a seal against the surrounding machine parts, in particular the channel-like section along which the Klassiergut is supplied ,
  • An embodiment provides that the closure unit unrolls on the material transported past.
  • This can be achieved advantageously by a cylindrical body.
  • a roller can be arranged with its axis transversely to the transport direction of the Klassiergutes and above the transport unit in such a way that it is mounted vertically variable to the transport plane. This makes it possible that the surface of the roller body regularly rests on the Klassiergut (or above this "floats"), which is moved between the roller body and the transport device.
  • the roller can press simultaneously on the Klassiergut and distributes this so on the conveyor belt.
  • a vibratory conveyor can be used as a transport device.
  • the roller may be guided with an associated shaft on corresponding sprung trained bearings; It is also possible to store the roller on or against shock absorbers, which allow the desired mobility of the roller body relative to the conveyor belt.
  • roller body pendulum Another possibility is to store the roller body pendulum.
  • a floating storage is desired, which allows depending on the type, size and amount of Klassiergutes a movement of the closure unit.
  • the closure body can also be designed in the manner of a circumferential guide band.
  • This guide band then runs more or less parallel and at a distance above the transport unit for the classifying material, but in such a way that the guide band rests at least with a portion on the material to be transported.
  • the guide belt is at least partially movable perpendicular to the transport direction of the Klassiergutes to dodge, as described above, different sized Klassiergut or to rest on this.
  • the guide band has the advantage of a most extensive sealing of the space between the transport unit and the housing of the channel-like section. This results analogously in a minimization of the cross-sectional area for the supply of false air.
  • the guide belt can also be arranged relative to the transport unit such that a guide path for the material to be classified tapers in the transport direction of the material.
  • the closure unit can be carried by friction as long as it is movable (rotatable); It can also be driven by a motor, for example synchronously with the transport unit.
  • FIG. 1 a Traumstromsichter is shown, the classifying room is marked with 10.
  • the classifying chamber 10 is traversed in the direction of arrow 12 with air.
  • the classifying 10 opens laterally a channel-like portion 14, which, perpendicular to the plane, about a Has rectangular cross-section.
  • a material to be classified here: mixed scrap
  • This material mixture contains parts of different sizes, different weights, different shapes and different materials.
  • heavy parts are shown in black and marked with 22, while lighter parts are shown in white and marked with 24.
  • This division corresponds to the classification in the classifying chamber 10, wherein heavy parts 22 are led away against the air flow 12 down from the classifying chamber, while lighter parts 24 are discharged from the air flow 12 upwards.
  • a closure unit 26 which here has the shape of a roller, so that there is a circular or annular shape in vertical section.
  • a roll body made of steel is marked with 28. Webs 30 protrude from its surface in the radial direction and extend over the entire axial length of the roller 26.
  • the (not shown) shaft of the roller 26 is suspended at the ends of springs, which are symbolized by the reference numeral 32, which in turn are attached to a frame 34. The spring force is adjusted so that the roller 26 can be moved in the direction of arrow 36, depending on how much material of which size and density is passed on the conveyor belt 18 below the roller 26.
  • roller body 28 in each case is in contact with the material 22, 24 to be classified and thus only the absolutely necessary cross section of the channel-like portion 14 is released, so that the suction of false air, symbolized by the arrow, is minimized.
  • the webs 30 contribute to a reduction of the open cross section of the channel-like portion 14 at.
  • Shock absorbers, self-aligning bearings or the like for fastening and guiding the closure unit (roller) 26 can also serve instead of a spring device 32.
  • FIG. 2 is shown another example of a closure unit, here in the form of a guide band 42 which extends in principle parallel to the conveyor belt 18.
  • the front end 42v in the transporting direction is guided in a floating manner, that is, the deflecting roller 44 is movable in the direction of arrow 36.
  • the gap between the guide belt 42 and the conveyor belt 18 is limited to the technically necessary degree, depending on which Klassiergut each between guide belt 42 and conveyor belt 18 is moved.
  • the opposite end of the conveyor belt can be made movable.
  • FIG. 2 is the classroom 10 only hinted.
