Definitions

  • the invention relates to a discharge device with a housing into which a discharge tube of a smoldering drum opens and from which a residue discharge chute opens, which opens into a conveyor device that ends at an outlet, a level meter being arranged on the residue discharge shaft.
  • Such a discharge device is known from DE 30 05 205 AI.
  • the Austragsvorrich ⁇ shown there processing for a pyrolysis plant is characterized in that an A ⁇ is stragsbehalter always filled in operation with overall carbonization to form a gas tight seal.
  • a level meter monitors the level in the container. At the outlet of the container, the smoldering residue is removed by a conveyor and brought to an outlet. With the conveying device, only so much residual material is transported away that the fill level in the housing does not drop below the position of the fill level meter.
  • a separation of the residual material into fine and coarse components is not intended for oeira acquaintances.
  • Such a separating device is known from EP 0086 488 A3.
  • a bar screen is provided, which is assigned to the vibration exciter.
  • the smoldering residue to be sorted falls on this rod screen.
  • the dwell time on the bar screen is not sufficient to get through the vibrations of the bar screen to shake off the fine residue from the coarse residue, because constantly new fine residue falls onto the coarse residue.
  • the invention was based on the object of supplementing a discharge device which has a gas-tight seal by a separating device which separates coarse residual material and fine residual material from one another and thereby cleans the coarse residual material from adhering particles of the fine residual material.
  • the conveying device has a profiled separating bottom, to which a rod screen is formed at the end facing away from the mouth of the residue discharge chute, that the vibrating exciter is assigned to the conveying device and that the rod sieve has a discharge opening for covers fine residue and ends at an outlet for coarse residue.
  • the fine residue is shaken from the coarse residue without further fine residue could fall onto the coarse residue. While the coarse residue rests on the elevated areas of the profile, the fine residue collects in the valleys of the profile. When the residual material reaches the molded rod sieve, the coarse residual material is cleaned. The fine residue then falls through the bar screen into the discharge opening for fine residue and the cleaned coarse residue is transported further via the bar screen due to the oscillation of the conveying device and falls into the outlet for coarse residue.
  • the residue discharge chute is bent in front of its mouth in the conveying device in the direction of the conveying direction. This ensures that the residual material always slides from the residual material discharge shaft onto the conveying device.
  • the residue discharge chute is against
  • Conveying device sealed by a flexible compensator. This provides a seal between these two components, which withstands the movements of the conveying device relative to the waste material discharge shaft.
  • the profiled partition consists for example of a profiled sheet or a profiled casting.
  • the dividing floor has a sawtooth-like cross section.
  • the dividing floor has, for example, curved recesses. This advantageously prevents coarse residues, which may include wire piles, from getting caught at the end of the partition.
  • edge-free partitions are arranged between the discharge opening for fine residue and the outlet for coarse residue. This also has the advantage that no wire bulges can get caught.
  • two separately controllable vibratory exciters are assigned to the delivery device.
  • the speed of the two vibration exciters can be different.
  • the advantage is also achieved that the use of a conveyor equipped with a vibration exciter compresses the sulfur residue plug in the residue discharge shaft, so that an entry of atmospheric oxygen into the sulfurization device is prevented better than previously possible.
  • the advantage is achieved that coarse residue is separated from fine residue much better than was previously possible.
  • profiled partition and bar screen can also be used for the separation or cleaning of other materials.
  • FIG. 1 shows a discharge device according to the invention.
  • FIG. 3 shows a plan view of a profiled separating base on which a bar screen is molded.
  • FIG. 1 shows a housing 1 of a discharge device into which a discharge tube 2 of a smoldering drum 3 opens, in which waste is carbonized. This produces carbonization gas and carbonization residue, which reach the housing 1 via the discharge tube 2.
  • the rotatable discharge pipe 2 is sealed off from the housing 1 via seals 4.
  • the carbonization gas leaves the housing 1 via a dispensing opening 5 arranged in the upper part, which is gas-tight with a device, not shown, for further treatment of the carbonization gas, for example with a high temperature combustion chamber is connected.
  • the solid smoldering residue falls down in the housing 1. From the lower outlet of the housing 1, which can be closed by an emergency slide 6, em residue discharge chute 7 starts.
  • a fill level meter 8 is arranged on the upper section of the residue discharge chute 7.
  • the conveyor is regulated so that there is always a dense bed of smoldering residue in the residue discharge chute 7, which prevents the backflow of gases, in particular atmospheric oxygen, from the smoldering drum 3.
  • the conveying device consists of a profiled separating floor 9, which is located in the vicinity of the mouth of the residual material discharge chute 7, and of a rod screen 10 formed on the separating floor 9 in the transport direction, and of a vibration exciter 11.
  • This can provide springs for Storage of the conveyor and eccentric rollers, which are driven by a motor, not shown, include.
  • the residue discharge chute 7 is sealed against the conveyor by a flexible compensator 12.
  • the vibration exciter 11 can be controllable. This can ensure that the residue discharge chute 7 is always sealed gas-tight by the residual material.
  • the vibration of the conveyor means that coarse and fine residues are separated from one another on the separating tray 9 and simultaneously moved. The fine residues then fall through the rod sieve 10 and reach a discharge opening 13 arranged there for fine residues.
  • This discharge opening 13 can open into a container, but also into a device for further treatment, for example in a high-temperature combustion chamber.
  • the coarse residual material is transported over the bar screen 10 to its end, from where it passes into an outlet 14 arranged there coarse residue falls.
  • a container 15 can connect to this outlet 14.
  • Edge-free partition walls 16 are arranged between the discharge opening 13 and the outlet 14, on which no residue remains.
  • Figure 2 shows a cross section through a partition 9, which has a sawtooth-shaped profile 9a.
  • the fine residual material accumulates in the valleys of this profile 9a, while the coarse residual material lies on the tips of the profile 9a.
  • the oscillating movement of the separating base 9 shakes off fine residual material which adheres to the coarse residual material, so that a coarse residual material remains as pure as possible.
  • FIG. 3 shows the transition from the dividing plate 9 to the rod screen 10.
  • the dividing plate 9 has curved recesses 9b. This prevents coarse residue, e.g. Wire wool, remains hanging at the end of the partition 9.
  • the discharge device on the one hand, backflow of atmospheric oxygen is avoided, and on the other hand, the coarse residue is almost completely separated from the fine residue. While the fine residue is usually treated further, the coarse residue consists of metal and glass parts that can be used directly as raw materials.

Abstract

L'invention concerne un dispositif de déchargement comportant un boîtier (1) dans lequel débouche le tuyau d'évacuation (2) d'un tambour de carbonisation à basse température (3). Un puits de d'évacuation de résidus (7) partant du boîtier (1) débouche dans un convoyeur qui se termine au niveau d'une sortie (14). Un système de mesure du niveau (8) est monté sur le puits d'évacuation de résidus (7). Il est prévu que le convoyeur présente un fond de séparation (9) profilé sur lequel est formé un crible à barreaux (10) à l'extrémité opposée à l'endroit où débouche le puits d'évacuation de résidus (7). Le crible à barreaux (10) recouvre une ouverture de déchargement (13) pour les résidus fins et se termine au niveau d'une sortie (14) réservée à l'évacuation de gros résidus. Un générateur de vibrations (11) est associé au convoyeur.
