Definitions

  • the invention relates to a mechanical method for material separation of metal-containing plastic mixtures and composites according to the preamble of claim 1 and to a compact device for performing such a method according to the preamble of claim 7.
  • the invention has for its object to provide a dry-mechanical process and plant technology solution, which in addition to the metal-plastic separation, the separation of non-ferrous metal fractions that can be processed directly to sinter powder with a defined composition.
  • the focus of the proposed technology should not be on separating raw materials that are as pure as possible, but on mixtures of materials whose further processing requires little effort to achieve secondary raw materials with a high added value.
  • the separation of high-purity raw material fractions should not be ruled out (e.g. when processing cable scrap and pre-cleaned mixtures).
  • the process is intended to separate copper components from the other diverse alloys from which the components are made, in order to reduce the proportion of non-ferrous metals to be further processed electrolytically.
  • the aim is to create a machine arrangement that is as simple as possible, that is suitable for processing a wide range of materials, and that fulfills the specified function with little disruption.
  • the most important parameters should be freely selectable.
  • a compact embodiment is to be chosen in which the necessary mechanical process stages and the air supply devices are combined in a portable machine.
  • the processing of equipment scrap according to the method according to the invention requires a coarse shredding by known cutting or tearing scrap shredders, which ensure the most homogeneous grain size and length of about 25 mm, with a sufficiently good digestion to obtain a qualitatively adequate iron scrap fraction.
  • the method according to the invention offers advantages through the use of the "Klauben" method step for non-ferrous metal piece deposition compared to the eddy current separating method which is otherwise usually used for non-ferrous metal deposition.
  • a special detection sensor system only the large clumps of metal can be separated, while small metal structures and composites that are to be further shredded cannot be detected.
  • Stainless steel and lead components can also be separated.
  • the metal-plastic separation by classifying and multi-stage density separation instead of the known electrostatic separation processes by means of L-C, offers the advantage that electrically conductive plastics, plastic particles wetted with conductive liquids or surface-metalized plastic particles do not get into the metal fraction and the influence of grain size on the separation quality at the the flow method used is larger due to the principle.
  • Classifying the classifier light fraction offers the advantage that a low-dust film / flake fraction can be obtained from device scrap, which e.g. can be used in the furniture industry. Metal debris can subsequently be better separated from the screened dust.
  • the advantages of the device according to the invention are that it is possible to carry out metal-plastic separation, film-fiber separation, dust separation, iron recovery and aluminum-copper separation from complex material mixtures such as mixed cables, populated printed circuit boards, metal-containing device housing parts and shredder fractions with a compact machine has a self-contained functionality and its area of application is expandable. While on the one hand high purities can be achieved in the metal fraction, on the other hand it is not possible due to the known devices for density separation used to cleanly separate stranded hair, aluminum foil pieces and copper-coated plastic parts (printed circuit board parts) from the light plastic fraction.
  • the tendency of copper strands to get caught and to form lumps on the air stoves used for density separation is used to largely separate these copper fractions from the other diverse non-ice metal alloys (in the density range of the copper), which are generally not in wire form.
  • Two air stoves arranged in a row also offer advantages when processing mixed cables by largely separating copper and aluminum.
  • the plastic fraction is selectively ground (see DE-OS 4213274.6), so that the thermosets and ceramics are ground, most (impact-resistant) thermoplastics are largely preserved as pieces, and the ductile metal fractions are predominantly pure copper, solder metal and aluminum be balled, after which they can be separated well with classification and density separation processes.
  • a further advantage for the processing of the non-ferrous alloy mixtures, which are then largely freed from copper wires, is that this results in an increase in the concentration of the noble metal components in this fraction.
  • the compact design, designed as a transportable container, allows mobile operation if required. This shows transpoitlogistic advantages that stationary processing plants do not offer.
  • the method according to the invention represents an environmentally friendly and inexpensive possibility of enriching valuable materials from metal-containing plastic waste and production residues. It forms a link between waste disposal and recycling of valuable materials by using dry-mechanical waste from metal-containing plastic and light scrap Recyclable secondary raw material concentrates can be produced at room temperature without the addition of solid or liquid auxiliaries, which, if necessary, can be further mechanically enriched and refined.
  • Fig.l shows the process flow diagram Fig.2 the inventive device
  • the free-flowing metal-containing plastic material arrives in a suitable conveyor in the device according to the invention after a magnetic separator, with which ferrous iron alloys can be removed.
  • a magnetic separator with which ferrous iron alloys can be removed.
  • a hammer mill (1) the composite material is broken, preferably at joints, by selective comminution, brittle components are greatly comminuted and larger pieces of ductile metal are only rounded off. It is relatively unaffected by larger metal and ceramic particles.
  • the use of a vertical hammer mill offers advantages when processing materials with a high content of bright metals.
  • cables and pre-cleaned, metal lump-free material fractions are preferably comminuted to a finer particle size.
  • a gravity classifier (3) after comminution ensures that the lumpy material is separated from light fiber, film and dust components, which are separated from the carrier medium by air in a dust separator (4) and can then be separated and used by suitable sieve classifying devices (5). Suitable oscillating movements of the sieve device (5) can cause fibers to agglomerate, which can then be separated by a further sieve (6).
  • a classifier heavy fraction is conveyed upwards again and freed from ferritic residual fractions with an iron separator (7). Classification is then carried out using a sieve (8).
  • the coarse fraction is passed through an electronically controlled chewing device (9), where at least one non-ferrous metal concentrate is separated.
  • the minimum piece size of the metal fraction to be separated can be set via the sensor sensitivity. This ensures that thin copper wires and other fine metal structures that are usually still attached large pieces of plastic stick, cannot be detected.
  • the fine fraction reaches devices for dry-mechanical density separation and is broken down into at least 3 basic fractions. In the device according to the invention, this is realized with two air stoves (10, 11) connected in series, which operate according to the inflow method. Vibrating movements of the inclined, air-flowed, textured surfaces of the air sources cause agglomeration phenomena of fine copper wires and strands.
  • the copper strands agglomerated into mats are regularly drawn off via a clearing device, while the heavy, lumpy metal particles leave the device via the heavy material discharge.
  • multiple use of pre-filtered exhaust air takes place inside the machine. Only a part of the air volume from the open circuit mills (1 and 2), wind sifter (3), compact dust extractor (4), blower (12) and return (13) via a distributor valve (14) into an exhaust duct (16) while the remaining air is returned to the air classifier (3) (partial air recirculation mode).
  • the amount of air required for the air sources (10 and 11) is dedusted using a compact filter (16) and only an adjustable amount of leakage air is transferred to the exhaust duct (16) via a distributor valve (15). If necessary, another air-consuming machine or an absolute filter can be connected to this exhaust duct.
  • the soundproofed containe-shaped system is brought to such a working height for operation that containers or conveyors can be placed underneath to hold the separated bulk goods.

Abstract

L'invention concerne une technologie, y compris une installation, permettant de séparer des mélanges de matières plastiques et des matières plastiques composites contenant des métaux, par exemple des déchets de l'électronique et de petits appareils, avec un prix de revient réduit, en économisant l'espace et en préservant l'environnement. Les procédés thermiques, chimiques et mécaniques connus ne sont pas suffisamment adaptés à la récupération de fractions de matériaux directement réutilisables. Dans le cadre de l'invention, il est possible non seulement de séparer dans une large mesure les métaux et les matières plastiques mais également de récupérer différentes fractions de métaux et de matières plastiques réutilisables qui constitueront, lors d'opérations de transformation ultérieures, une source importante de produits, y compris les fractions de métaux non ferreux, qui peuvent être transformés sans électrolyse en produits de la métallurgie des poudres. Les composants ferreux sont largement éliminés des matériaux composites ou des mélanges de matériaux préalablement broyés si nécessaire, et ces derniers sont transférés, selon le cas, à un broyeur à marteaux (1) ou à un granulateur à couteaux (2). Après une séparation par air (3), la fraction légère est classée en au moins trois plages de tailles de particules. Les composants ferreux restants sont également éliminés de la fraction lourde et celle-ci est également classée. Une fraction grossière passe par une machine à trier (19) où au moins un concentré de métaux non ferreux est séparée. La fraction fine est transférée à un séparateur densimétrique mécanique à sec (10, 11) et elle est décomposée en au moins trois fractions de base, et les torons en cuivre sont agglomérés. Le procédé est mis en oeuvre dans une installation spéciale, compacte et transportable, de type conteneur.
