Definitions

  • the invention relates to a process for the production of recycled plastic material, in particular recycled PET material, which is at least substantially free of toxic contaminants, the entire plastic material being in at least one treatment room, e.g. a cutting compactor is subjected, by at least one rotating processing element, to a processing which causes heating and possibly compression and / or crystallization of the material, in which, in the presence of impurities, volatile substances are released, the presence of which is indicated by at least one sensor sensitive to these substances ,

  • WO 01/21321 Essentially physical processes work at much lower temperatures so that the structure (in particular the molecular chain length) of the recycled plastic is essentially preserved.
  • One method suitable for this (WO 01/2132) consists in first heating the PET material to be recycled in the course of a pretreatment and drying it at elevated temperature and crystallizing it at the same time. This material is then plasticized or melted previous main treatment under vacuum conditions a renewed drying and crystallization at an elevated temperature compared to the pretreatment.
  • a device suitable for carrying out this method is known from AT 407 235 B. This method and this device work satisfactorily when handled properly. If the method or the device is used improperly, however, there is a risk that undesirable toxic residues are contained in regenerate batches, so that these regenerate batches are therefore not food-safe.
  • PET polyethylene terephthalate
  • the invention has for its object to improve a method of the type described in such a way that with comparatively little investment in plant equipment using commercially available plant components it is possible to correctly assess whether the plastic material to be recycled is suitable or not, whether the treated plastic material is suitable for direct contact with food ,
  • the invention solves this problem in that the sensor continuously monitors the entire material introduced into the treatment room in the treatment room and / or a gas outlet connected to it for existing impurities and in the treatment room and / or in the Gas removal detected impurities causes contaminated goods to branch off from the material flow passing through the treatment room.

Abstract

La présente invention concerne un procédé pour produire un produit en plastique recyclé qui est exempt d'impuretés toxiques. Ce procédé consiste à faire chauffer le produit dans une enceinte de traitement, éventuellement à le comprimer et/ou à le faire cristalliser, afin que les impuretés présentes libèrent des substances volatiles. Cette libération est indiquée par un capteur sensible à ces substances, qui contrôle en continu le produit dans l'enceinte de traitement et/ou dans un système d'évacuation des gaz relié à cette enceinte. Si des impuretés sont détectées, le capteur dévie le produit contaminé du flux de matériau traversant l'enceinte de traitement. La présente invention concerne également un dispositif conçu pour mettre en oeuvre ce procédé, qui comprend un boîtier (2) destiné au traitement du produit en plastique, dans lequel se trouve un organe de traitement (16) entraîné en rotation. Un capteur (28) sensible aux substances volatiles libérées par les impuretés toxiques dans l'enceinte de traitement (3) détecte les gaz libérés par le produit dans l'enceinte de traitement (3) ou dans un système d'évacuation des gaz. Si des impuretés toxiques sont détectées dans le matériau à traiter, une ouverture d'évacuation (36) pour le produit présentant des impuretés toxiques, venant s'ajouter à une ouverture de sortie (22), est libérée.
