Definitions

  • the invention relates to a method and a device for processing valuable materials to be recovered from automobile shredder debris and / or electronic scrap in the form of long, thin metallic long parts, such as wires, pins or the like, which may be present as spinning (vault), in particular in one Grain fraction above 10 mm.
  • a method and a device are known from DE 40 41 529 A1 with which from a pre-classified, preferably sieved, single-layer solid mixture, the long parts are picked up by brushing from the surface of the conveyor, and are actually "picked".
  • the brushes used to pick up thin wires are relatively soft and densely bristled, while for picking up thicker wires, such as from automobile shredder waste, the brushes are coarser and also have thicker bristles.
  • the solid mixture is thrown onto an inclined conveyor, which consists of a conveyor belt or two like pins and hooks or the like. provided, endlessly revolving conveyor belt.
  • Body-shaped or granular constituents of the solid mixture should slide against the direction of the inclined endless conveyor under the influence of gravity and roll or slide into a first collecting container, while the long parts are conveyed upwards by the pins, hooks etc. and after exceeding the top dead center can be thrown from the endless conveyor into a second container.
  • a wire roller can also be arranged at the low-lying end of the inclined endless conveyor to support the separation effect.
  • the invention has for its object to provide a method and an apparatus which allow improved processing of the long, thin, metallic constituents of the solid mixture, in particular in grain fractions above 10 mm.
  • This object is achieved with a method according to the invention in that the solid mixture on an endlessly rotating, bristled endless conveyor belt
  • bristle band and the material to be recovered is clamped into the bristle band by spreading and then closing the bristle and unloaded at a delivery point by spreading the bristle band again.
  • a targeted spreading or opening and closing of the bristle belt which is preferably deflected at least three times in the course of its circulation, is carried out and thereby achieved that the materials to be recovered are spread out when the bristles of the conveyor belt are spread first chamber between the bristles, while the body-shaped materials cannot penetrate the bristles due to their geometry and essentially remain on the belt surface or the bristles.
  • the bristle band wraps around at least three deflections, of which the third deflection (seen vertically) in the direction of transport is arranged lower than the second deflection.
  • Stationary sliding shells could be used as U - steering; however, since there must be a drive drum for the bristle band anyway, it is advisable to design all the deflections as rollers.
  • the bristle band runs onto the deflection rollers, the bristle spreads on its free, outer area when it is in contact with the deflection drums.
  • the spreading width in the radial direction of the deflection drum is dependent on the smallest permissible bending radius of the bristle band as well as the effectively selected diameter of the deflection roller and the length of the bristles.
  • the area of the bristle spread at the first deflection roller could also be used for the task.
  • the long parts are embedded between the bristles of the bristle band.
  • the bristle band leaves the radius of the second deflecting drum, it takes on a straight, elongated shape again, whereby the spread on the outer side of the bristle band that is specifically forced by the band bending is canceled out.
  • the long, thin parts are held firmly in the bristle while the coarser parts on the surface of the bristle band are bristled due to their configuration. remain or are pressed there by the closing bristles.
  • the third deflection roller arranged at a lower level, there is an elongated downward slope, which preferably runs at an incline, for which purpose the third deflection can be arranged at a distance from the second deflection, in which the bristle is closed.
  • the coarser parts fall or slide downwards on the bristle band in the transport direction, while the long, thin parts continue to be held in the bristle.
  • the bristle belt then runs onto the third deflection drum, which is advantageously also designed as a drive drum, so that the bristle is spread again, whereby the long, thin parts are released and fall down .
  • the course of the bristle band and the spreading and closing of the bristle can be further influenced by a fourth deflection which is arranged downstream of the third deflection and is in turn arranged lower than this.
  • One embodiment of the invention provides a tensioning roller which dips into the bristle band from the bristle side after the last deflection. Depending on the immersion depth, this can be used to change the tension and, depending on its position and arrangement in relation to the deflection, the wrap angle at the last deflection, which is equivalent to a larger or smaller band section with spread bristles.
  • the second deflection is assigned a pressure means acting on the bristle band from above. This can be designed as a concave or convex, pivotable pressure plate, in a disc segment construction as a rotating disc or, advantageously, with a variable depth, which is inserted into the bristle band and is arranged in a swinging manner.

  • the vibration generator for example a vibrator or tapping device, on the bristle band, the chambering - if the vibration generator is assigned to the upper run - or the falling out of the long parts - if the vibration generator is assigned to the lower run - favored.
  • an increasing conveying path advantageously follows between the first and the second deflection of a horizontal conveying path.
  • the feeding of the solid mixture is shifted to the horizontal area of the upper run of the bristle belt in the horizontal conveying path.
  • This opens up the possibility of pinching the thin, long particles in the deflection area from the horizontal to the obliquely rising part of the upper run and consequently entraining them up to the conveyor section area which slopes obliquely to the second deflection roller.
  • With a correspondingly steep design of the inclined conveyor section area self-metering can be achieved since only a subset of the material is transported on. Those parts that do not have sufficient contact with the bristles slide back and are only taken away at a later time. In this case, the solid mixture need not be fed to the bristle band in one layer.

  • the bristle 8 is or the bristles 9 are closed at the discharge end 6 in the region of the horizontal conveying path 15, because as soon as the bristle band 10 leaves the radius of the first deflection roller 12, it assumes an extended position; the spreading forced by the band bending on the outer side of the bristle band 10 is thereby eliminated. As soon as the bristle band 10 then runs onto the second deflection roller 13, the bristle 8 spreads again at its free, outer end in the area of the system on the deflection drum 13. By spreading the bristles 9, the long, thin wires 7 have the opportunity to sit between the individual bristles and to store or chamber them there.

Abstract

L'invention concerne un procédé permettant de séparer des matériaux recyclables à récupérer à partir de ferrailles de shredder d'automobiles et/ou de systèmes électroniques et qui se présentent sous forme de fines pièces métalliques (2) longues, comme des fils, des broches ou équivalent, notamment dans une fraction granulométrique supérieure à 10 mm et éventuellement enroulés sous forme de pelotes. Le mélange de solides est placé sur une bande transporteuse (10) sans fin pourvue de poils de brosserie (8). Le matériau à récupérer (2) est entraîné dans la bande transporteuse par ouverture et par fermeture du système de poils de brosserie (9) et est déchargé à un point de jetée (18) par réouverture de la bande transporteuse pourvue de poils de brosserie (10) et par libération des matériaux. Une installation de séparation présente à cet effet une bande transporteuse pourvue de poils de brosserie (10) comportant au moins trois systèmes de renvoi (12, 13, 14) dont le troisième (14), vu dans le sens de transport, est disposé au-dessous du deuxième (13).
