Definitions

  • Known cremation ovens have a grate consisting of several transverse struts, one after the other, seen in the longitudinal direction of the coffin.
  • the distance between two struts is usually 300 mm.
  • the coffin with the body to be cremated is placed on this grate, which closes off a main combustion chamber of the cremation furnace. The combustion process can now begin.
  • the coffin is designed so that the coffin lid burns through first. The body water then evaporates, and the body is then burned with the lower pan of the coffin.
  • Bones of the body are often only incompletely burned. These rest on the grate and cannot fall through the grate in an unfavorable position. It is therefore necessary to manually open the coffin insertion door of the main combustion chamber and, on the one hand, to promote the combustion process with a poker and, on the other hand, to position bones so that they can fall through the grate. Above all, the lower and upper arm bones as well as the upper and lower leg bones are problematic in this respect.
  • the invention is based on the problem of creating a device for carrying the coffin within a main combustion chamber of a cremation furnace, by means of which the combustion process is improved and in particular no manual stoking and grate cleaning intervention from the outside is required.
  • the coffin can be set in a shaking motion by the movable grate during the combustion process, so that burnt layers are detached from unburned layers. As a result, the combustion material is stoked. Furthermore, the movement of the Rust, cross the bones that are initially seen in the longitudinal direction of the unburned coffin so that they also fall through the grate. A manual intervention from the outside is therefore no longer necessary due to the device according to the invention.
  • the grate is preferably formed by a plurality of rollers, one behind the other, seen in the longitudinal direction of the coffin, rotatable about its axis.
  • the rollers can advantageously be driven in a rotating sense, it being expedient if the rollers are driven individually. As a result, the rollers can be driven in the same direction, sometimes in opposite directions, so that a particularly good stoking effect is achieved. Due to their rotary drive, the rollers can also be used as a conveyor to retract the coffin. However, the feet of the coffin must be removed or wooden slats placed under them.
  • the cremation furnace 10 is designed in the usual way, namely with a main combustion chamber 11 and a glow zone 12.
  • the glow zone 12 and the main combustion chamber 11 are separated from one another by a rotary plate 13, on which the post-combustion of the falling solids is also carried out (afterburning zone 43).
  • a new coffin 14 is being burned in the main combustion chamber 11, the ashes of the previous coffin can burn out in the annealing zone 12.
  • the ash rests on a rotating ash grate 15 within the annealing zone 12.
  • the cremation furnace 10 has the usual lining 16, which is enclosed by an external cooling jacket 17. Cooling air can be introduced into the cooling jacket 17 through an inlet 18, which then flows around the brick lining and is discharged through an outlet 19.
  • the coffins 14 to be burned can be moved into the main combustion chamber through a coffin insertion door 20.
  • the exhaust gas generated during the cremation is discharged through an exhaust pipe 21.
  • the coffin 14 rests with its trough 22 on a grate 23.
  • the grate 23 is formed from rollers 24, 25, 26 and 27 lying one behind the other in the present case, seen in the longitudinal direction of the coffin 14.
  • the rollers 24..27 extend transversely to the longitudinal direction of the coffin 14.
  • the clear distance between the rollers 24..27 is 300 mm.
  • the rollers 24..27 are mounted in the main combustion chamber 11 in such a way that they are arranged flush below a coffin insertion level 42.
  • the roles 24..27 are essentially from a tube 28, for. B. made of heat-resistant (approx. 500 ° C) and oxidation-resistant steel, which is coated with a heat-insulating solid jacket 29.
  • the casing 29 is guided into the area of bores 30 in the lining 16 of the cremation furnace 10.
  • the tube 28 of each roller 24.27 is guided into the cooling jacket 17. Cooling air can be introduced into the tube from the cooling jacket 17 through radially directed bores 31. The cooling air flows through the tube and exits the tube 28 through bores 32 at the other end.
  • the diameter of the tube 28 is advantageously 100 mm with a wall thickness of more than 8 mm.
  • the jacket 29 is made of a wear-resistant ramming compound with a heat resistance of approx. 1200 ° C. and a thickness of approx. 100 mm. This results in a total diameter of the rolls 24-27 of 300 mm.
  • Shafts 33 and 34 are fixedly attached to the end faces of the tube 28.
  • the tubes 28 are supported by the shafts 33, 34 by bearings, in particular ball bearings 35.
  • 17 bearing flanges 36 are attached to the outside of the cooling jacket.
  • Each of the rollers 24..27 can be driven by a motor.
  • an electric rotary motor 37 is provided, which is attached to the shaft 34.
  • the rotary motor 37 is supported on the bearing flange 36 via a torque arm 38.
  • Each of the rollers 24..27 has its own rotary motor 37.
  • Each of the rotary motors 37 can be controlled independently.
  • Each of the rollers 24..27 can thus be driven individually.
  • the rotary motors 37 are thermally decoupled from the cremation furnace 10, for example by an intermediate insulating layer (not shown).
  • rollers 24-27 are driven in a rotating sense.
  • the rollers 24..27 are briefly driven (e.g. 1/5 of a turn) counterclockwise and then clockwise.
  • the maximum speed of the rollers 24..27 is about 0.5 min -1 .
  • Already burned layers fall off due to the movement of the coffin 14. Oxygen access to unburned layers is facilitated and the fire is thereby fueled.
  • the rolls 24..27 do not have to have a round cross-section as shown. You can also advantageously have a triangular, quadrangular or polygonal cross section.
