Definitions

  • the invention relates to a device for sorting metal parts, in particular scrap pieces, according to their composition in the passage over a conveyor belt, under which an X-ray or isotope radiation source is fastened near the underside of the belt, the rays of which penetrate the conveyor belt in order to reach the metal parts, thereby collecting of the beams emitted by the metal parts, at least one detector is provided, to which a computer is connected, which analyzes the electrical signals generated by the detector and controls downstream sorting devices.
  • a method and a device for sorting metal parts in a pass through a transport device in which a continuous sorting according to different metals and alloys is achieved.
  • the metal parts placed on the running transport device move through X-rays or isotope beams within a short range of motion and the beams emitted by the metal parts, in particular X-ray spectra, are collected by at least one detector and analyzed by a computer that controls downstream sorting devices.
  • the object of the invention is to improve a device of the type mentioned in the introduction in such a way that a high measurement and analysis accuracy is achieved.
  • the conveyor belt is made of plastic or rubber and has small openings or openings, that the conveyor belt is curved in a channel shape transversely to the longitudinal direction, and that the radiation source and detector are arranged approximately radially to the belt curvature and in particular emit or emit rays in this direction received.
  • Metal parts 1, in particular smaller and larger pieces of scrap, are fed one by one onto a conveyor belt 3 by a feed device 2, in particular through an inclined shaking plane.
  • the material of the conveyor belt is largely transparent to X-rays and is made of plastic or rubber.
  • the conveyor belt can also regularly have openings, openings or be of wide mesh. Fer The conveyor belt is then curved in cross section in such a way that the longitudinal edges lie higher than the intermediate central region.
  • the revolving conveyor belt 3 guides the metal parts under a radiation protection hood 4, which overlaps the belt.
  • a radiation generator 5 and, for example, a detector with a Dewar vessel 6 are fastened next to one another radially to the belt curvature, transversely to the belt direction, below the belt when the energy-disperse system is used.
  • the generator 5 generates X-ray, gamma or isotope beams, which are generated by an X-ray tube or isotope and are directed radially to the band curvature on the metal parts 1.
  • the characteristic rays emitted by the metal parts in accordance with their type of metal and their type of alloy, in particular (X-ray) radiation spectra (X-ray fluorescence radiation), are collected by the detector 6 arranged next to the generator and converted into electrical pulses. Liquid nitrogen is used to cool the detector using an energy-dispersive method. Since the beam generator 5 and detector 6 are arranged under the conveyor belt, there is a largely equal distance from all metal parts so that the beams reaching the detector do not fluctuate too much.
  • the electrical signals generated by the detector are fed to a computer with a sorting process control, which compares the measurement signals of the detector with signals that have already been stored, in particular X-ray fluorescence patterns of analyzed metals or alloys, and then controls the sorters located on the conveyor belt accordingly.
  • sorting devices 7 are provided next to or above the conveyor belt 3, which throw the metal parts into containers 8 arranged next to the belt and behind the belt in accordance with the control signals given by the computer.
  • the sorting can be done by mechanical switches or by air nozzles that blow the metal pieces to be separated off the belt.
  • the beam generator and detector can be attached to the side or above the metal parts.
  • a radioactive substance is suitable as a radiation source.
