Definitions

  • the present invention relates to a device for separating particles of different electrical conductivity in an inhomogeneous sorting material by means of deflection by an alternating magnetic field, which is induced by a rotationally symmetrical magnetic device, wherein the sorted material is guided through the magnetic field.
  • a non-ferromagnetic metallic element In an eddy current separation, a non-ferromagnetic metallic element is moved along magnetic field lines through a magnetic field. By the law of induction, a voltage is induced in the metal body - and so-called eddy currents are formed. In turn, these eddy currents cause a magnetic field that surrounds the metal body (Biot-Savart's Law). If the magnetic field thus generated encounters a magnetic field which has an opposite direction, the particle is repelled. In the case of eddy current separation, magnetic fields generate permanently changing magnetic fields and thus a force acting on non-ferromagnetic particles. This force is large enough to accelerate the particles to separate them from other materials.
  • This separation occurs mainly by ejecting the non-ferromagnetic metals in the same direction in which the material to be separated moves.
  • the method is used in EP 0 898 496 B1 and WO 97/44137 A1 ,

  • a pole wheel is arranged at 45 ° to the belt movement, particles can be deflected horizontally according to their conductivity and either discharged from the conveyor belt or separated at the end.
  • the machine achieves good results compared to other eddy current separators, especially in the area of small particles.
  • the oblique magnet roller results in a very long machine design, which makes integration into existing processes and systems difficult. Further, multiple roll systems can be constructed to an acceptable length to increase throughput, degree of separation, or selectivity.
  • sorting processes are necessary which offer a high degree of selectivity and allow the greatest possible output.
  • waste streams can not be separated, often considerable financial value is lost and, on the other hand, part of a raw material obtained using energy, which i.a. greenhouse gas emissions, rendered unusable, which would be of great environmental concern.

  • the transport device has a very low surface roughness so as to keep the expended force of the Wirbelstromscheiders as low as possible. The surface roughness is chosen so that the particles are barely caught by the conveyor belt.

  • the particles perform this movement until they leave the flow of material and are either carried along due to the frictional forces of the conveyor belt or reach the end of the magnetic device.
  • the sorted material which is not magnetized due to its physical properties, continues to run without deflection and leaves the conveyor belt at the same position where it was placed.
  • the deflected particles perform a sort of wave motion, similar to a sinusoid, during sorting.
  • This impulsive deflection leads to the fact that light material composites can be opened up and the spreading is increased.
  • the impulsive concern of the magnetic field causes the so-open material composites to re-undergo the sorting process upon reentering the alternating magnetic field, the particles to be sorted each undergo a sorting by conductivity upon each entry into the magnetic field.

  • the device according to the invention also called helical vortex flow separator, allows the separation of non-ferromagnetic particles from a process stream at a substantially vertical angle (about 80 ° to 90 °) to the transport direction. This creates an interaction between friction force on the conveyor belt and generated by eddy currents particle acceleration.
