Definitions

  • the invention relates to a plant for treating residues of inhomogeneous residues from a thermal waste disposal system, especially from a pyrolysis plant.
  • the pyrolysis residue largely contains non-combustible materials Shares, which essentially consist of an inert fraction, such as glass, stones or ceramics, as well as from a metal fraction put together.

  • the present invention has for its object a To specify the plant for the treatment of residues of inhomogeneous residues, which is a safe and continuous separation of the Residual guaranteed without clogging of individual Components occur.
  • the coarse screen serves to separate coarse residues from the inhomogeneous residue.
  • the remaining fine residue is in the wind sifter, also known as the zigzag sifter, into a light residue and a heavy residue Cut.
  • the previous separation of the coarse residue is of enormous importance for the functionality of the air classifier, because coarse material is in the air classifier's channel can jam.
  • the one brought into the zigzag sifter fine residue has a largely homogeneous size distribution on.
  • the coarse sieve preferably has a spiral coiled rod that extends in the direction of its spiral axis extends and is rotatable about this.

  • the spiral 40 is only on one side, namely on the rotary tube 32, attached. Your spiral end facing away from the rotary tube 32 is free of fasteners and is not supported. The spiral 40 will therefore become unpaved Curve towards the end due to their own weight.
  • the spiral 40 can also be attached on both sides. It is preferably curved.
  • the inhomogeneous residue IR is over the feed device 36 abandoned and due to the inclination of the rotary tube 32nd and due to the rotational movement in the conveying direction 44 to the spiral 40 transported there.
  • This is the coarse residue GR separated from the remaining residue R by only the coarse residue GR is transported further by the spiral 40 becomes.
  • a major advantage of the coarse screen 2 with the spiral 40 can be seen in the fact that even more fluent Coarse residues GR through the rotary movement in a simple manner Direction of conveyance 44 is transported.
  • An essential aspect of the coarse screen 2 is the curvature of the Spiral 40, through which the distance between two successive Turns during rotation.
  • Residual part R which has jammed in the spiral 40, rotates with the spiral 40 and is raised. at the same time the distance between the turns widens, so that the Residual part R can fall down.

Once these cross tabs 88 to the end pulley 82 reach, the distance between the two cross brackets 88 and the jammed residue part falls out. The inertial sieve 30 is therefore removed due to the Design with the revolving treadmills 84 between Cross brackets 88 clamped residues R automatically.
