Definitions

  • the present invention relates to a separation plant and a method for separating a fraction containing non-ferrous metals, in particular from electronic scrap processing according to the preamble of claim 1 and claim 12.
  • the object of the present invention is to provide a separation plant and a method according to the preamble of claim 1 and claim 12, respectively, in order to produce high-quality recyclable fractions of non-ferrous metals with simple means in a cost-effective manner.
  • sorting of the crushed and largely Fe-free fraction takes place directly after the shaping of the particles and thus indirectly increases the copper concentration in the flat part fraction and an increase in the aluminum concentration in the spherical part fraction, in which case at least one high-quality material fraction can be separated from both the flat part and the spherical part fraction in a simple manner.
  • a fraction of valuable material containing predominantly copper and a predominantly piece of board is obtained.
  • a fraction of recyclable material is obtained which contains over 90% aluminum and contains over 85% heavy metals (eg Cu, Pb, Ms, Zn; density greater than 4 kg / dm 3 ).
  • the effort for an otherwise complex dedusting is also significantly reduced, since there is no need for very fine comminution and the number of sightings that require dedusting can be significantly reduced.
  • the amount of air to be extracted and dedusted can be reduced by about half.
  • non-ferrous metal separator If a non-ferrous metal separator is connected upstream of the feed, the quality of the recyclable material fractions can be improved by separating off disturbing residues and largely trouble-free operation of the downstream stages. e.g. by separating any vaults formed by residues. If the non-ferrous metal separator is designed as a very fine pole separator, a fraction that is particularly highly concentrated in non-ferrous metals can be fed in via the feed.
  • the eddy current separator is designed as a rough pole separator.
  • a partial fraction can be split off, from which a further fraction of valuable material can already be split off in a simple manner by means of a sighting or a non-ferrous metal separation.
  • baffle plate is provided adjacent to the feeder and at a distance from the conveyor belt, it can largely be prevented that spherical particles which unfavorably spring back after an impact on the conveyor belt get into the flat part fraction.
  • Seating tables or air stoves are particularly suitable for classifying the flat part and ball part fractions. Training the shredder as a mill supports the formation of flat and spherical particles.
  • Fig. 1 is a schematic representation of a separation system
  • FIG. 2 shows a schematic section of the separation system according to FIG.
  • the separating system shown in FIG. 1 comprises a shredder designed as a hammer mill 1, which is followed by a magnetic separator designed as a magnetic roller 2 and a sieve designed as a vibrating sieve 3.
  • An NE separator designed as a very fine pole separator 4 is arranged downstream of the sieve 3.
  • the NE separator 4 is followed by a sorting device 5, which comprises a conveyor belt 6, an eddy current separator 7 and a feed 8.
  • a first setting table 10 and a second setting table 9 are arranged downstream of the sorting device 5.
  • a third setting table 11 is connected downstream of the screen 3.
  • the feed 8 is arranged above the conveyor belt 6 at the head end (right).
  • the conveyor belt 6 is received by two deflection rollers 12, 13, one of which is provided with a rotary drive.
  • the eddy current separator 7 is arranged eccentrically with respect to the axis of the deflection roller 13 in the transport direction of the conveyor belt 6.
  • baffle plate 14 adjacent to the end of the feed 8 is arranged in such a way that spherical (approximate) particles which spring back from the conveyor belt 6 - in the direction of transport of the conveyor belt - bounce off there and are thrown back to the head end.
  • the fraction in the present exemplary embodiment is ground in the hammer mill 1 with grinding action to a grain size of less than 30 mm, so that the grain spectrum is in the range from approximately 0 to approximately 30 mm.
  • the comminuted fraction is fed to the magnetic separator 2, with which Fe-containing particles are separated off.
  • the remaining fraction is then sieved in the vibrating sieve 3 with a sieve hole diameter of approximately 4 mm.
  • the fine fraction obtained thereafter is fed to the setting table 11 for screening and into a valuable fraction containing predominantly copper in the form of spherical wires, and into a predominantly contaminant such as pieces of board, wood splinters, plastics, etc. containing residual fraction split.
  • the concentrated coarse fraction is fed to the sorting device 5 and sorted into a flat part fraction comprising essentially flat, plate-like parts and a ball part fraction comprising essentially spherical, rather body-shaped particles.
  • the particles fall from the feed 8, for example a feed trough, onto the end of the conveyor belt 6 provided with the eddy current separator 7.
  • the flat part fraction is fed to the setting table 9 for screening and separated there into two recyclable material fractions, one essentially containing copper and the other predominantly coated pieces of board.
  • the spherical part fraction is sifted by means of a setting table 10, whereby a recyclable material fraction containing over 90% aluminum and a recyclable material fraction containing over 85% heavy metals is generated.
  • the sieve 3 is designed with a sieve hole diameter of approximately 20 mm and an NE separator 11 is provided instead of the third setting table 11 from the first exemplary embodiment.
  • This design of the separation system is particularly suitable for fractions containing non-ferrous metals, such as z. B. from shredded car and / or electric motor scrap.
  • the material in the area of the upper grain spectrum can be split off from such a fraction in a simple manner by sieving and further separated into valuable material fractions by means of the NE separator 11.
  • the fine fraction remaining after the screening is then, if necessary after NE enrichment (or depletion of impurities), fed to the sorting device 5 by means of an NE separator 4 and processed as in the first exemplary embodiment.
  • the sieve 3 is omitted in a third exemplary embodiment of the separation system and the comminuted and largely Fe-free non-ferrous fraction is fed directly to the sorting device 5, if appropriate after an non-enrichment.
  • This design of the separation system is particularly suitable for non-ferrous fractions, the components of which have a grain diameter of approximately less than 20 mm.
  • the separation system and the process ensure the more cost-effective production of high-quality fractions of non-ferrous metals with simple means.

Abstract

L'invention concerne un séparateur pour une fraction contenant des métaux non ferreux, provenant en particulier d'une préparation de ferrailles électronique, pourvu d'un désintégrateur suivi d'un séparateur magnétique. L'invention vise à permettre la production de fractions de matières valables qualitativement riches en métaux non ferreux par des moyens simples et de manière économique. A cet effet, le séparateur magnétique est suivi d'une bande de transport comportant un séparateur à courants de Foucault côté tête et une conduite débouchant dans la zone du séparateur à courants de Foucault côté tête, la rotation du séparateur à courants de Foucault et le sens d'acheminement de la bande de transport étant dirigés vers la fin de la bande de transport. L'invention concerne en outre un procédé pour la séparation d'une fraction contenant des métaux non ferreux provenant d'une préparation de ferrailles électronique, caractérisé en ce que cette fraction est broyée dans un désintégrateur en une taille de particule comprise entre 30 et 40 mm et en ce que la fraction broyée est libérée de ses constituants ferreux au moyen d'un séparateur magnétique. Le procédé selon l'invention permet de produire des fractions de matières valables qualitativement riches en métaux non ferreux par des moyens simples et de manière économique.
