Definitions

  • the invention relates to a device for discharging combustion residues in combustion plants, in particular waste incineration plants, with a water-fillable trough, to which the combustion residues are fed via a chute, a partially water-fillable discharge chute that leads obliquely upward from the trough and at its top End has an overflow edge, and a reciprocating piston for conveying the combustion residues from the tub to a circulation device arranged in the application chute of the type of a conveyor belt or a scraper chain, which in turn conveys the combustion residues through the discharge chute to the overflow edge.
  • a device of this type is suggested, for example, by the combination of the patents CH-360 152 and CH-867 121, but would have the disadvantage that it could not be used when burning wood waste, tree bark and such sorted, sorted waste.
  • This type of garbage produces small amounts of very light and poorly wettable ash, which settles very slowly in the water. Also, the water level cannot be lowered because the air seal between the Discharge chute and the chute through the ash alone would not be guaranteed.
  • DE-OS 2 739 396 and DE-OS 2 539 615 devices are known in which the discharge of the combustion residues from the tub to the chute by means of the piston is only possible if the chute is sufficiently filled with combustion residues. Only then, after each stroke of the piston, can enough combustion residues reach the trough from the chute to fill up the piston displacement there and form a plug that is conveyed to the chute during the next stroke. In the facilities mentioned, the combustion residues can only be conveyed through the chute if the chute is sufficiently filled with combustion residues.
  • the object of the invention is to eliminate these disadvantages mentioned and to provide a device of the type mentioned at the outset which, even if the chute is incomplete or insufficiently filled, does not have to be shoveled by hand through the maintenance opening and which is also suitable for conveying combustion residues from wood waste, Tree bark and such sorted crushed garbage is suitable.
  • the device according to the invention is characterized by the features specified in claim 1.
  • Advantageous developments of the invention result from the dependent claims.
  • Combustion residues fall from a combustion system (not shown) through a chute 2 into a trough 3.
  • a piston which can be moved back and forth, of which only the front face 4 is shown, pushes these combustion residues into a chute 5, which leads obliquely upwards from the tub 3 and has an overflow edge 6 at its upper end.
  • the stroke of the piston to its extended position leads its front surface, designated 7 in this position, to approximately the location designated 8, where the bottom of the tub 3 merges into the bottom of the chute 5 via a sealing or end cross-member, ie in substantially below the wall 9 of the chute 2 facing the front surface of the piston.
  • the trough 3 and the chute 5 are filled with water 10, the water level fluctuating between an upper water level 11 and a lower water level 12.
  • a discharge device 13 is arranged on the bottom of the chute 5, which essentially consists of a conveyor belt indicated by dashed lines, which is designed as a plate, hinge or Z-belt, or as a scraper chain, in particular as a two-strand scraper chain. This discharge device 13 conveys the combustion residues through the chute 5 to the overflow edge 6.
  • the closing device 14a can be designed as a flap which is freely suspended on the wall 15 by means of joints 30.
  • the termination device 14b can be designed as a rubber apron hanging freely on the wall 15. Thanks to the closing device 14, which is immersed in the water 10, the water level can be lowered to the lower water level 12 if necessary, without thereby allowing the air from the chute 5 to the tub 3 to create what would affect the combustion conditions in the furnace.
  • closure device 14 prevents the suspension of the ash in the chute 5 from being swirled in the water by the turbulence of the suspension in the trough 3, which enables the ash in the chute 5 to settle faster and then be transported away by the discharge device 13 to become.
  • the discharge device 13 consists, as indicated above, essentially of the conveyor belt 17, which is guided over two deflection rollers 18 and 19. Both guide rollers 18 and 19 should preferably be assigned chain tensioning devices, not shown in any more detail.
  • the conveyor belt 17 moves around a schematically shown conveyor frame 20 with a closing surface and is covered at the bottom by a base plate 21.
  • a blow-off device 22 is arranged near the upper deflection roller 18. With this, air or a flushing medium is applied to the back of the conveyor belt 17 and adhesive slag parts are removed in this way. Another flushing device can be assigned to the lower deflection roller.
  • Both the discharge device 13 and the trough 3 are underpinned by support columns 23, 24 which stand on a floor 25.
  • Traverses 26 can be provided as carriers and retaining traverses 27 on the conveyor belt 17 or the skeleton 20. These can be used to prevent the cinder cones from slipping back when household waste, in particular untreated, is discharged.
  • the retention crossbeam 27 is normally designed so that the slag pin cannot slide back on the one hand and on the other hand does not hinder the pin feed. This is ensured by a wedge-shaped shape.
  • the conveyor belt 17 can be equipped in the upper area (conveyor skeletons area 20) with at least one retaining crossbar 27 and in the lower area with at least one driving crossbar. This means that all described operating states can be operated without changing the chain or conveyor belt.
