Definitions

  • the invention relates to a sorting device comprising a magnetic separator of non-ferrous metal particles and pieces comprising a conveyor belt extending between a rear return roller and a front active cylindrical casing around which this conveyor belt is partially wound. to join and partially wrap around at least one other downstream return roller located below and in front of the active cylindrical envelope.
  • the present invention will find application in the field of industrial waste recycling comprising ferrous and non-ferrous metal products.
  • the particles to be sorted are poured onto the upper strand of the conveyor belt over which extends a magnetization device for the purpose of removing the particles that can be magnetized.
  • the waste to be sorted should be devoid of particles and ferrous pieces.
  • the magnetic system or polar wheel To return to the magnetic system or polar wheel, it consists of a succession of permanent magnets or electromagnets arranged radially relative to an axis of rotation corresponding to the axis of rotation of the active cylindrical envelope.
  • the latter is driven by a speed of rotation substantially slower than that of said pole wheel so as to subject the particles and pieces remaining to be sorted, especially the particles and non-ferrous pieces, to an alternating magnetic field.
  • electric motors are made of different magnetic and nonmagnetic metallic materials so that, after grinding, it remains in the presence of particles and pieces consisting of a mixture of these materials pursuing totally random trajectories.
  • the particles originating from the first device are first poured onto a vibratory plate which itself feeds , distributed, these particles on the conveyor belt of the device downstream.
  • this second sorting operation uses specific detection means acting more particularly in the portion of the conveyor belt between the upstream and downstream return roller, detection device coming to control sorting means located immediately beyond the downstream return roller.
  • these sorting means may be constituted by a pneumatic nozzle ramp from propelling, for the purpose of its recovery, a particle detected by the upstream detection means.
  • these sorting and ejection means can still be mechanical type.
  • the current sorting devices are generally binary type, knowing that beyond the first sorting operation, the particles must again be properly distributed in monolayer and controlled rate on the conveyor belt of the device. sorting downstream and there is therefore a duplication of the means for a reproduction of the functions already provided during the first sorting operation.
  • the present invention is intended to respond advantageously to this problem.
  • it is within the framework of an inventive step that it was imagined to exploit the geometry and the characteristics of a magnetic separator, as described in the document EP-A-0439983 , to carry out and cascade various sorting operation, without it being necessary to repeat, between these operations, the multiple functions of distribution and presentation of the particles and pieces to be sorted.
  • the invention relates to a device for sorting particles and pieces of waste for recycling, in particular non-ferrous metals
  • a device for sorting particles and pieces of waste for recycling comprising a conveyor belt on which are poured the particles and pieces to be sorted, this conveyor belt extending between a rear return roller and a front active cylindrical casing incorporating a magnet system in the form of a pole wheel designed to subject the particles and pieces to an alternating magnetic field, beyond said active cylindrical casing, the conveyor belt being extended , again, between this last and a downstream return roller, characterized in that beyond the active cylindrical envelope, the particles on the conveyor belt are subjected to detection means designed to control downstream sorting means.
  • the return roller downstream of the active cylindrical envelope is located below the latter.
  • the sorting means controlled by the detection means are constituted by ejection means located beyond the downstream return roller.
  • the present invention relates to a device for sorting particles and pieces 2, waste, especially industrial, for recycling, more particularly, particles and pieces of ferrous and non-ferrous metals.
  • this sorting device 1 comprises a conveyor belt 3 describing a looped circuit coming to extend between a rear return roller 4 and an active cylindrical envelope 5.
  • this conveyor belt 3 On this conveyor belt 3 are poured particles and pieces 2 to sort. Note that to ensure a perfect distribution of these particles on the conveyor belt 3, this spill can be provided by a vibrating plate upstream, not shown in the figure.
  • a magnetization device 6 can be extended (there still not shown), for attracting these magnetic particles to evacuate laterally.
  • a magnetic system in the form of a pole wheel 8 designed to subject the particles 2 deposited on the strip conveyor 3 to an alternating magnetic field.
  • tray 9 for sorted particles on which are projected said particles downstream of the active cylindrical envelope 5, under the influence of the rotating magnetic field.
  • the pole wheel 8 is composed of a plurality of permanent magnets or electromagnets 10 arranged radially relative to the axis of rotation 11 of the wheel.
  • said pole wheel 9 can be mounted centrally in the active cylindrical envelope 5 or eccentrically by adopting, at this time, a section smaller than the internal section of said active cylindrical envelope 5.
  • the position of the axis 11 of the pole wheel 8 can be defined adjustable in an angular range around the axis of rotation 7 of the active cylindrical envelope 5.
  • this conveyor belt 3 can, but not necessarily, partially wrap around this roller downstream 12 to join the rear return roller 4.
  • this downstream return roller 12 is disposed below the active cylindrical envelope 5 so as to ensure the partial winding of the conveyor belt 3 around the latter on a determined zone lying preferentially in the two upper quarters of this active cylindrical envelope 5.
  • this downstream return roller 12 is disposed below the active cylindrical envelope 5 so as to give the conveyor belt 3 an inclination which is, at most, equal to 45.degree. compared to the horizontal.
  • the sorting device 1 comprises detection means 13 to which the particles 2 remaining on the conveyor belt 3 downstream of the active cylindrical envelope 5 are subjected, detection means 13 designed capable of controlling sorting means. 14 to precisely separate the detected particles from other particles.
  • the detection means 13 may take different embodiments.
  • these detection means 13 may be of the inductive type reacting according to the nature of the detected metals, of the capacitive, infrared, optical or laser beam type.
  • these detection means 13 may be constituted by a camera for detecting, perfectly the pixels, different types of materials composing the particles to be treated.
  • laser beam detection means with which a spectrometer is associated, make it possible to detect, here again, the nature of the particles moving on the conveyor belt 3, downstream of the active cylindrical envelope 5.
  • the sorting means 14 consist, advantageously, of ejection means located downstream of the downstream return roller 12.
  • these ejection means may be of the pneumatic type and constituted by an air nozzle ramp activated under the influence of the detection means 13 to eject a previously identified particle.
  • These ejection means can still be hydraulic or mechanical type. In this case they may take the form of a series of small flapper hammers, again making it possible to separate from other particles, those identified by the detection means 13.
  • downstream return roller 12 may be mounted, as the case may be, a pole wheel to subject, again the particles to a rotating magnetic field and sort, therefore, non-metal particles ferrous material distinguished by their conductivity with respect to the previously sorted particles at the height of the active cylindrical envelope 5.
  • downstream return roller 12 can also be mounted a magnetic device for retaining the previously unsorted magnetic particles.
