Definitions

  • the invention relates to a detoxification device for an incineration plant, in particular for incinerating waste, according to the preamble of claim 1.
  • the invention is based on the object of specifying a detoxification device with a lever construction which is constructed in a space-saving manner and in which the points of application of the forces transmitted to the lever are not are far apart or - preferably - practically overlap, which relieves the axles and axle bearings considerably and therefore sensitive parts are not exposed to excessive loads.
  • the advantages achieved by the invention lie, in addition to a small space requirement, in a longer service life achieved by comparatively low mechanical loads and a lower maintenance requirement.
  • the deslagging device shown in Figs. 1 and 2 is arranged at the end of a combustion grate, not shown, of an incineration plant, the incombustible combustion residues falling off the grate, such as slag and other, e.g. metallic parts, get into a vertical slag shaft 1, the mouth 2 of which protrudes into a slag pan 3 which is filled with a water filling 4 to a level which closes the mouth 2 of the slag shaft 1 against the ingress of air.
  • the drive for the ram purifier is arranged on the side of the slag trough 3 opposite the extension track 6. This has the task of moving a thrust plate 10 arranged in the slag tray 3 from a rearward position, in which the slag shaft 1 is released, into an extending position at the beginning of the extending path 6.
  • the two positions of the push plate 10 are designated R for the rear position and A for the extended position.
  • a push rod 12 is supported, which can be designed essentially as a hollow tube, for example as a square hollow tube.
  • a push rod 12 is arranged on the back of the push plate 10, which over the Level 5 of the water filling 4 protrude and are pivotally mounted there on a lever 14 by means of a joint 15.
  • the lever 14 is designed as a two-armed lever, between the arms 16, 17 of which a pivot shaft 18 is arranged.
  • the pivot shaft 18 extends over the width of the slag pan 3 and is on the outside of the end face of the slag pan 3 by means of bearings, e.g. Rolling bearings, stored in two bearing housings 19 which e.g. can essentially form a continuation of the side walls of the slag tray 3.
  • the two-armed pivot lever 14 is fastened to the pivot shaft 18 within the two bearing housings 19 and is aligned with the push rod 12.
  • the pivot lever 14 and the push rod 12 thus lie in the same vertical plane of movement.
  • a support crossbeam 20 is fastened, on which a double bracket 21 for an articulated bearing 22 of one end of a thrust piston drive 24 is supported.
  • the push piston drive 24, e.g. a hydraulic lifting cylinder, is articulated at its other end to the arm 17 of the pivot lever 14 and provides the pushing force for the displacement of the thrust plate 10.
  • Fig. 1 the linkage formed from the push rod 12 and the pivot lever 14 is shown in the rear position of the push plate 10. It can be seen that the joint 15, which connects the push rod 12 to the pivot lever 14, is located far above the level 5 of the water filling 4 in the slag pan 3. But also in the extended position of the push plate 10, see FIG. 2, the joint 15 is also above the level 5 of the water filling 4. This ensures that none of the sensitive joints of the push piston drive 24 and the linkage 12, 14 and the swivel shaft 19 are within the water filling 4. In addition, it is also achieved that the movements of the Linkage 12, 14 lie in the same vertical plane, so that no additional moments are exerted.
  • the slag shaft 1 and the slag pan 3 are welded together from sheet steel.
  • the push plate 10 slides on the inside of the bottom of the slag pan 3.
  • the slag pan 3 is usually supported on two bases 26, 27 which rest on foundations 28, 29.
  • the slag tray 3 is thus at a distance above the foundation floor (not shown) so that there is sufficient space for the arrangement of the thrust piston drive 24 below the slag tray 3.
  • the slag tray 3 has an access door 30 on both side walls which is large enough that an operator can get inside the slag tray.
  • the slag shaft 1 is also welded together from steel plates, is firmly connected to the slag pan 3 and also has an access opening 31.
