Definitions

  • the invention relates to a discharge device with a housing, into which a discharge pipe of a smoldering drum opens and from which a residue discharge chute emanates, which goes into a Conveyor opens, which ends at an outlet, on A fill level meter is arranged in the residue discharge shaft.
  • Such a discharge device is from the DE 30 05 205 A1 known.
  • the discharge device shown there for a pyrolysis plant is characterized in that a discharge container is always filled with smoldering residue during operation is to form a gastight seal
  • a level meter monitors the level in the tank. At the exit of the container is the smoldering residue by a conveyor removed and brought to an outlet. With only as much residual material is removed from the conveyor that the level in the housing is not below the Position of the level meter drops.
  • a separation of the residual material into fine and coarse components is not intended for the acquaintance.
  • Such a separating device is known from EP 0086 488 A3.
  • a bar screen is provided, the one Vibration exciter is assigned.
  • the smoldering residue to be sorted falls on this bar screen.
  • Below the bar screen there is an outlet for fine residue and at the end of the bar screen is an outlet for coarse residues available.
  • the invention was based on the object of a discharge device, which has a gastight closure, by a Separating device to complement the coarse residue and fine Separates residue and thereby the coarse residue from adhering particles of the fine residue.
  • the Conveying device has a profiled partition the one facing away from the mouth of the residue discharge chute End of a bar screen is formed that the conveyor a vibration exciter is assigned and that the Bar screen covers a discharge opening for fine residual material and ends at a coarse residue outlet.
  • the advantage is achieved that on the partition that is caused by the vibration exciter Vibrations are set, the fine residue from the coarse Residual material is shaken off without further fine residual material could fall onto the coarse residue. While the coarse residue on the raised parts of the profile the fine residue collects in the valleys of the Profiles. When the residue reaches the molded bar screen, the coarse residue is cleaned. The fine residue then falls through the bar screen into the delivery opening for fine residue and the cleaned coarse residue due to the vibration of the conveyor over the The bar screen is transported further and falls into the outlet for coarse residue.
  • the residue discharge chute is in front of it Mouth in the conveyor in the direction of the conveyor bent towards it. This ensures that the Residual material always from the residual material discharge shaft to the conveyor slides.
  • the profiled partition consists, for example, of a profiled sheet or from a profiled casting.
  • the partition has a sawtooth-like cross-section.
  • the partition has, for example curved recesses. This is advantageous prevents coarse residue, the wire crust may include, hooked at the end of the partition.
  • the conveyor is, for example, two separately controllable Vibration exciter assigned.
  • the Speed of the two vibration exciters may be different.
  • the conveyor consists of a profiled partition 9, which is near the mouth of the residue discharge chute 7 is located, and from one in the transport direction rod screen 10 formed on the partition 9, and from a Vibration exciter 11. This can use springs for storage the conveyor and eccentric rollers by a Motor, not shown, are included.
  • the residue discharge chute 7 is against the conveyor sealed a flexible compensator 12.
  • the vibration exciter 11 can be controllable. This can ensure be that the residual material discharge shaft 7 always by the Residual material is sealed gas-tight.
  • This discharge opening 13 can be placed in a container, but also in a device for further treatment, e.g. open into a high temperature combustion chamber.
  • the rough residue is transported over the bar screen 10 to its end, from where he into an outlet 14 arranged there for coarse residue falls.
  • At this outlet 14 can Connect container 15. Between the discharge opening 13 and edge-free partition walls 16 are arranged at the outlet 14 where no residue gets stuck.
  • FIG. 2 shows a cross section through a partition 9 has a sawtooth-shaped profile 9a. In the valleys this Profiles 9a accumulates the fine residual material during the coarse residue lies on the tips of the profile 9a. By the oscillating movement of the partition 9 becomes fine residue, which adheres to the coarse residue, shaken off, so that a coarse residue that is as pure as possible remains.
  • Figure 3 shows the transition of the partition 9 to the bar screen 10.
  • the partition 9 has curved Recesses 9b. This prevents being coarser Residue, e.g. Wirewalls, hang at the end of the partition 9 remains.
