  • This in turn comprises a separation chamber and an air inlet leading into it, through which the cross-flow device introduces air into the separation chamber in an angular direction of flow to the main longitudinal extension direction of the flow channel.
  • the separation chamber comprises at least a first separation region adjacent to the air inlet and at least one second separation region located farther away from the air inlet.
  • a separation device in particular designed as a baffle element, is arranged between the first and the second separation region.
  • the separation device combines a down drafting process with a cross-flow sifting.
  • light parts such as foils in the flow channel are initially drawn off the discontinued material flow towards the exit.
  • heavier materials falling downwards are decelerated differently in their fall depending on the density and mass, and reach the area of the separation chamber in which they are blown and further separated by means of a cross flow
  • stones or the like land in the first separation area or are reflected there by the separation device, and on the other hand, the lighter fraction through the cross flow over the separation device are passed away into the at least one further separation region.

  • the detection device can be of any nature. For example, it may be an NIR sensor. Such a sensor can be adjusted very selectively to very specific material components of a material mixture.
  • the detector detects, for example, a plastic part, then this is flown through by a material inflow means and selectively removed from the rest of the material flow.
  • the corresponding detector is preferably arranged in the direction of fall above the Materialanströmstoffs so that the Materialanströmstoff can be activated with the appropriate time delay and immediately deactivated again on the control upon detection of a separate part, so not more parts be detected and separated from the Materialanströmstoff, which should not be discarded.

  • a material input region 34 is arranged, through which a material flow 2 can be introduced with therein, to be separated parts in the flow channel 3.
  • the air flow 5 is preferably generated by the fact that behind the end 36 of the flow channel 3, a fan is connected. By the moving air in the flow channel 3, the material 2 is sucked in the material input area.
  • an air inlet 31, 32, 33 can be provided at several points, via which additional air can be drawn in from the outside area.
  • Such an air inlet may be provided with a controllable valve, so that the intake amount can be varied.
  • a separation chamber connects, which is part of a cross-flow device 4 and a plurality of sections 44, 45, 49 includes.
  • a channel 41 is charged with air, which injects air in the example shown transversely, in particular perpendicular, to the vertical direction Z or to the main longitudinal extension direction of the flow channel 3 into the separation chamber.
  • the amount of air to be injected can be varied via a valve or frequency converter 43.
  • another air inlet 33 may also be provided above the channel 41, which sucks air into the region 49 of the separation chamber immediately before the start of the flow channel 3.

  • the separation device 46 is designed as a partition which can be pivoted in the direction of the arrow P 2 and can be extended or shortened in the direction of the arrow P 1.
  • the device 1 functions as follows: As already described, the air flow 5 is generated in the flow channel 3 by means of a fan, a material mixture 2 being supplied to the material inlet region 34 and being sucked into the interior 35 of the flow channel 3 as a result of the air flow. Lighter objects in the stream 2 of material are entrained in the upward flow and reach the exit 36, while heavier parts due to gravity, sink down towards the separation chamber. There they reach the area 49 of the separation chamber.

With this measure, therefore, an additional air flow is achieved, which further enhances the buoyancy in the flow channel 3.
  • FIG. 2 is exemplary in FIG. 2 shown separating device 1 shown in the system diagram.
  • the so-laden air enters a separator 9, on which light parts present in the air stream, such as films, paper or the like are deposited.
  • the air flowing through the fan 10 then passes to a filter 12, on which particles still present in the air are filtered out and optionally collected in a collecting device 13, while the cleaned air 14 leaves the line 8 behind the filter 12.
  • the system works with the intake of fresh air, and also the fan 42 blows fresh air into the system for the cross flow.
  • FIG. 5 A variant of in FIG. 4 shown configuration is in FIG. 5 shown, the only difference is that here the return line 16 between the fan 10 and filter 12 is located.
  • This configuration is particularly advantageous when the dimensioning of the filter 12 is important, since in this case the use of energy due to smaller volume flows through the filter 12 is minimized.
