Definitions

  • the present invention relates to a combustion carrier as part of a conveying device in a plant for burning off explosives, with a base plate and a trough made of scale and temperature-resistant material mounted on the base plate for receiving the explosives, the combustion system having a combustion reactor which the Burn-off carriers pass one behind the other in assembly line operation through an entrance area and through an exit area.
  • the term "explosives” is intended to encompass both the explosive substances, to which the explosives belong according to a recognized definition, and the explosive substances.
  • the latter are, in relation to the present invention, solid or liquid substances which, when certain test methods are carried out, are chemically converted to a certain extent by heating without complete solid confinement or by an unusual stress due to impact or friction without additional heating either high-tension gases arise in such a short time that a sudden pressure effect is caused (explosion) or an effect occurs that is equivalent to the explosion.
  • the explosive substances also contain substances that were not produced for the purpose of blasting or shooting, for example organic peroxides as catalysts, gas release agents for today's foam and plastics technology, some pesticides and much more.
  • This includes, for example, the generally known mixture " Thermit” which is understood to mean mixtures of aluminum and iron oxide which convert to aluminum oxide and iron with strong heat development. This heat development is used, for example, for rail welding.
  • Explosives are defined as solid, liquid and gelatinous substances and mixtures of substances that are produced for the purpose of blowing up or blowing up. They include characterized by their metastable state, i.e. they are capable of a rapid chemical decomposition reaction without the addition of other reaction partners, in particular without air-oxygen.
  • metastable state i.e. they are capable of a rapid chemical decomposition reaction without the addition of other reaction partners, in particular without air-oxygen.
  • the combustion of explosives is a rapidly developing process, which is relatively unpredictable in terms of its progress and can hardly be influenced after the initiation of the decay reaction, and which is also highly exothermic, that is to say with great heat development of up to 3000 ° C in the vicinity of the combustion source .
  • Such a temperature is reached in a matter of seconds and is maintained throughout the combustion process, so that the immediate surroundings of the combustion source, and in particular the combustion carrier, heat up extremely strongly.
  • the consequence for the erosion carrier is that he deformed irreversibly due to the action of heat, yes "crumpled", so that the known combustion supports of the type mentioned at the outset have only a very limited reusability.
  • combustion carriers are used successively and alternately, by first loading them with the explosives to be burned off, then feeding them to a combustion reactor or generally: to a combustion site and after the combustion of solid or liquid has ended Reaction products are disposed of.
  • a pot annealing furnace system for firing porcelain and other ceramic products is known.
  • This pot-type annealing furnace is tunnel-shaped and the products to be burned are transported on wagons that pass one behind the other in assembly line operation through an entrance area and through an exit area of the furnace tunnel.
  • the loading areas of the wagons are separated from each other by bulkheads, the bulkheads being arranged perpendicular to the base plate of the wagons and at least in height exceeding the loading area of the wagons.
  • US Pat. No. 1,893,123 also belongs to the field of furnaces for ceramic articles.
  • the base plate there of a carrier for the ceramic products is designed as a chassis with wheels, and an upper coupling plate is fastened to the front side of the base plate, which has the width of the base plate and which projects beyond the base plate in the longitudinal direction to such an extent that it fits into a corresponding transverse groove of an adjacent, connectable wagon.
  • combustion carriers as part of a conveyor in a combustion system is known from EP-A-0 349 865, where the combustion carriers pass through a security building in circular operation through an entrance area and through an exit area, in which the explosives are detonated.
  • the high heating of the erosion carriers that occurs during the erosion of the explosives is cooled down in a cooling zone after the erosion.
  • a loading zone then follows the cooling zone in the direction of transport, where the explosives are placed on the burn-off carriers, safety devices in the form of doors or security gates being arranged between the fire site and the cooling zone and between the cooling zone and the loading zone.
  • the object of which is to construct a combustion carrier as part of a conveying device in a plant for burning off explosives in such a way that a high degree of operational safety is achieved despite the aforementioned assembly line operation.
  • the advantages of the solution according to the invention lie, in particular, in the fact that the tub is surrounded on the outside by cooling air due to its attachment spaced apart from the base plate, and the enormous heating of the tub body is thereby considerably reduced.
  • the fastening of the tub body to the base plate according to the invention has proven to be extreme in tests in this regard with regard to stabilization and the dimensional stability of the tub body successfully proven.
  • the tub body tends to an extremely reduced extent to the described deformation and, in particular due to a distribution of the columnar supports over the surface of the tub bottom, essentially resumes its general shape after the burning process has ended.
  • the bulkheads fulfill three essential functions: firstly, when the explosives are burned off on a combustion carrier Sparks can be prevented from spilling onto subsequent combustion supports (which are still loaded with explosives); on the other hand, the high-temperature thermal radiation that arises during the combustion is to be diverted upward, in order to prevent the thermal radiation from spreading to the subsequent combustion carriers that still carry explosives.
  • the closure of the entrance and the exit area of the combustion plant by the bulkheads should ensure that the combustion reactor is constantly flowed through by a defined air flow in the conveying direction of the combustion carrier, which fulfills several important tasks: on the one hand, it provides the quantitative transport of the gaseous reaction products and the aerosols contained therein in a cleaning device connected downstream of the combustion reactor. Furthermore, the air flow should limit the inlet temperature of the exhaust gases on the equipment belonging to the downstream cleaning device and overall the air temperature in the combustion reactor to a maximum value of, for example, about 300 ° C.
  • the air flow serves to remove sparks that spray up during the combustion and, finally, the oxygen content of the air flow in the combustion reactor sets oxidizing conditions which promote a residual combustion of the substances not oxidized during the combustion.
  • the trough is formed so as to be angularly cantilevering at its upper edge.
  • the resulting circumferential edge, as it is directed outwards, is not caught by the hot exhaust gas flow that arises when the explosives burn off and is directed upward, and thus remains at a relatively cooler temperature, which contributes to the dimensional stability of the tub during the burn-off and afterwards.
  • the bulkheads of the burn-off supports also have a cleaning function within the burn-up reactor, the inner walls of which are preferably lined with temperature-resistant fiber material, in that the width of the bulkheads is such is chosen that the side edges of these bulkheads slide along the fiber material.
  • a number of solid reaction products settle which, according to the advantageous further development, are “scraped off” by the bulkhead walls when they pass them on the conveyor line.
  • the width of the bulkheads is less than that of the base plate by a defined amount, and that the base plate engages under the lining with fiber material on the inner walls of the combustion reactor laterally. This ensures that the residues scraped off from the lining of the inner walls do not remain in the burn-off reactor, but fall onto the base plate and are transported out of the burn-up reactor with the burn-off carrier.
  • the use of the combustion carrier within a combustion system is preferably a further development of the invention, according to which the base plate is designed as a chassis with wheels, and according to which an upper coupling plate and a lower coupling plate are attached to one end face of the base plate, which have the width of the bulkhead and which protrude beyond the base plate in the longitudinal direction so far that they accommodate the base plate of an adjacent, coupled-up combustion carrier, at least in their edge region between them.
  • the coupling area of the mobile erosion carrier designed in this way has a number of advantageous functions: on the one hand, the thrust forces are transmitted from one erosion carrier to the adjacent erosion carrier via the respective base plates.
  • the upper and lower coupling plate By the width of the upper and lower coupling plate corresponding to the width of the bulkhead and by the two coupling plates of a combustion carrier reaching over or under the base plate of the adjacent, coupled combustion carrier, it is achieved that the lined-up combustion carriers in the combustion reactor provide continuous partitioning against the floor form, whereby the roadway of the erosion carrier is protected from falling reaction products. Furthermore, the upper clutch plate causes the abutting There is no explosive on the end faces of the base plates of adjacent erosion carriers that could be detonated by the clutch pressure.
  • these can have devices for receiving or holding bodies which contain explosives to be burned off. These bodies can be separated or opened ammunition parts of various sizes.
  • a further development is to increase the operational safety of the erosion carrier, according to which, in the direction of travel, a brush made of conductive material is arranged in front of each wheel of the erosion carrier, which, when pressurized, slides on the lane in front of the edge and is conductively connected to the erosion carrier.
  • This brush essentially fulfills two advantageous functions: on the one hand, electrostatic charges between the roadway and the erosion carrier are dissipated via the brush, and on the other hand, the brush acts as a cleaning brush for the lane.
  • These advantageous developments of the erosion carrier can further be supported by the fact that the material of the wheels of the erosion carrier and the material of the lane in the combustion reactor is coordinated in a favorable manner.
  • An example of material pairing is plastic for the wheels and brass for the lanes.
  • the erosion carrier 1 shows a plurality of combustion carriers 1 which are coupled one behind the other by means of couplings 20 and which are designed in the form of mobile carriages.
  • the erosion carrier 1 essentially consists of a base plate 4 and a trough made of scale and temperature-resistant material, for example steel, which is mounted on the base plate 4 and which receives the explosives to be burned off.
  • the tub 2 is mounted at a distance from the base plate 4 by means of column-like spacers or supports 6, so that a space remains between the tub floor and the base plate 4.
  • the supports 6 are arranged in a symmetrical five-piece shape, as a result of which the forces generated during the burning process due to thermal stressing of the tub material are derived in a particularly advantageous manner and thus a deformation of the tub is counteracted.
  • the erosion supports also have wheels 14 mounted under the base plate 4, so that the erosion supports 1 by means of a corresponding one own or third-party drive can be moved on a conveyor line through the burn-up reactor.
  • each erosion carrier 1 located in the direction of travel, a bulkhead 12 is fastened vertically on the base plate 4, which both jumps sparks from the erosion carrier 1, which is currently loaded with explosives, to subsequent erosion carriers, as well as a spreading over of the thermal elements formed during the erosion Prevent radiation on the subsequent erosion carrier 1.
  • the upper and lower coupling plates 18, 20 extend so far beyond the base plate 4 that they accommodate the base plate 4 of the adjacent, coupled-on combustion carrier 1 between them.
  • the adjacent erosion carriers shown here in FIG. 1 have not yet been completely coupled together; this is only the case when the adjacent base plates 4 touch on their end faces, since the thrust forces are thus transmitted from one erosion beam to the other.
  • the upper coupling plate 18 prevents explosives in the coupling area - in particular in the area of the two abutting base plates 4 - which could be caused to explode by the pressure of the abutting base plates 4.
  • the lower coupling plate 20 additionally ensures that neither explosives nor reaction products can fall down into the lane 25 between the combustion carriers.
  • the lower coupling plates 20 also form, in cooperation with the abutting base plates 4 and the upper coupling plates 18, a continuous bulkhead against the floor, which favors a cooling air flow sliding between the undercarriage supports 1 between the undercarriages.
  • the upper edge 8 of the tub 2 is formed so as to be cantilevered around the circumference, so that a circumferential border 15 is present is not detected by the upward thermal radiation and gives the trough 2 considerable stability during the burning process.
  • FIG. 2 shows a plan view of one of the erosion carriers 1 of FIG. 1.
  • the size distribution of the trough 2 with its surrounding border 15 in relation to the bulkhead wall 12 located on the end face 10 of the erosion carrier 1 and to the base plate 4 can be seen.
  • the width of the bulkhead 12 exceeds that of the trough 2 in order to ensure the shielding explained above against sparks as well as against the thermal radiation of the preceding combustion carrier.
  • the width of the bulkhead 12 is, however, less than that of the base plate 4, which will be explained below with reference to FIG. 3.
  • the symmetrical division of the spacers or supports 6 can be seen from FIG. 2, which gives the tub 2 good dimensional stability despite the high thermal stress.
  • Fig. 3 shows a cross section through a burn-up reactor 9, the inner walls of which are lined with temperature-resistant fiber material 13, for example rock wool.
  • a suction nozzle 19 is shown, which is arranged in the exit area 5 above the exit passage 5 'of the burn-off reactor 9 (Fig. 4).
  • the burn-off carrier 1 rolls with its wheels 14 on a travel path 25 which is embedded in the concrete foundation 21 of the burn-up reactor 9.
  • a brush made of conductive material (not shown) fastened to the erosion carrier 1, which is conductively connected to the erosion carrier 1 and thus an electrostatic one, slides under pressure Charging of the erosion carrier 1 or the wheels counteracts.
  • the lanes of the route 25 have, for example, a brass coating and the wheels 14 of the erosion carrier 1 are made of plastic.
  • the base plate 4 grips laterally under the fiber material lining 13, as a result of which the solid reaction products scraped off from the lining 13 by means of the bulkhead 12 are collected by the base plate 4 and transported out of the burn-up reactor 9.
  • Fig. 4 shows the burn-up reactor 9 in a longitudinal section.
  • a large number of combustion carriers 1 are coupled in series by a conveyor (not shown here) one after the other only through an input passage 3 'through the input region 3, then are conveyed further into the combustion region 7 to the burners 22 and then the combustion reactor 9 through the output passage 5 'leave again.
  • a spark flap 23 is arranged, which is intended to prevent sparks from the burn-off area 7 from jumping onto the burn-off carriers already loaded with explosives in the entrance passage 3 '.
  • the combustion reactor 9 is flowed through by a continuous air flow in the direction of arrow 26, which is generated by an air intake device via one or more intake ports 24 and a suction port 19.
  • This air flow can be influenced by a Venetian blind 27 which is adjustable and lockable with respect to the slat position.
