Definitions

  • the invention relates to a method for extracting foreign bodies from a bulk material flow, and an apparatus for performing this method.
  • This conveyor can be designed as a conveyor trough, conveyor chute, sieve or belt conveyor (US-A-4,929,342).
  • the transport takes place either via the inclined conveyor by means of gravity or according to the vibratory conveyor principle or by belt.
  • the object of the present invention is to provide a method for extracting foreign bodies from a bulk material flow with which high degrees of separation can be achieved with large throughput quantities. Furthermore, an apparatus for carrying out the method is to be proposed.
  • the suction is not limited to the bulk material flow transported from a conveying device, but also includes the parts in free fall. Naturally, suction is also carried out at the outlet edge of the nozzle, so that the material flow located on the further conveying device is also subjected to cleaning. It is obvious that the material flow is shifted by falling from the first conveying device to the further conveying device, so that now other particles lie on the surface and are subjected to suction.
  • the invention further relates to a device for extracting foreign bodies from a bulk material flow with a conveying device for transporting the bulk material flow and a nozzle arranged essentially above the conveying device for suctioning the foreign bodies.
  • the conveying device has a discharge edge in the region of the nozzle and that a further conveying device is provided for transporting the discharged bulk material flow.
  • conveyor devices can be designed as conveyor troughs, conveyor chutes or sieves.
  • the discharge edge can be designed as a small elevation in order to control the discharge of the bulk material flow.
  • the nozzle has a flap which is variable in height on the side of the incoming bulk material flow.
  • the flap height can be adjusted to the bulk material flow manually or automatically.
  • the nozzle has a pivotable flap on the side of the bulk material flow being transported away.
  • the flap is pulled inwards by the negative pressure in the nozzle.
  • the device according to the invention consists of a first conveyor device 1, which is provided with a discharge edge 2 at its end.
  • a further conveyor device 3 is arranged below this conveyor device 1.
  • a suction nozzle 4 is provided in the region of the discharge edge 2.
  • the nozzle 4 has on the side of the incoming material flow a flap 5 which is adjustable in height b, on the opposite side a further flap 6 is provided which is designed to be pivotable about a point 6a and thus also adjustable in height a .
  • This flap 6 can be designed to swing freely and / or be fastened.
  • the air flow sucked in through the nozzle 4 flows through the device in various ways.
  • the device according to the invention is designed so that the main part of the air flow is fed through the gap 7 between the first conveyor 1 and the further conveyor 3.
  • certain air streams flow directly into the nozzle 4 directly under the flaps 5 and 6, but the adjustability of these flaps 5 and 6 is intended to keep these air flows relatively low.
  • Another possibility for the air flow is given by the fact that the conveying devices 1 and 3 are designed to be air-permeable in a manner known per se. This can either be due to the fact that vibrating sieves are used or ventilation slots are provided in the case of conveyor chutes, which forces a certain air flow to also pass through the bulk material flow located on the conveyor device 1 and loosen it up.
