Definitions

  • Mist pots are generally cylindrical in shape and, in order to achieve a uniform and complete burn-up, are ignited centrally with an igniter located in the cover in the cylinder axis.
  • the ignition beam ignites a secondary detonator, which is inserted or cast in the middle of the mist set.
  • the resulting fog emerges through holes in the upper area of the cylinder jacket. These holes are closed during storage and transport, the sealing material being selected such that it burns or melts when the mist pot is ignited and thus releases the outlet openings for the mist.
  • mist pots A major disadvantage of such mist pots is that the cover for receiving the igniter must be relatively stable and that the mist pot must have a height which is considerably greater than the height of the load, since the outlet openings in the jacket take up space. In spite of this space requirement, the openings cannot be chosen to be of any size, which would be necessary for optimal combustion behavior, since the stability of the mist pot suffers work steps and thus associated with effort and costs. Since the cover carries the igniter, it is generally not possible to provide the holes in the cover for reasons of stability.
  • the present invention has for its object to provide a mist pot that does not have the disadvantages mentioned, that is easy to manufacture, has a higher degree of filling and shows an improved combustion behavior.
  • mist pot consisting of a box with edge lining, pressed mist set, firing set, screw-in igniter and outflow openings for the mist in that the mist set is arranged in a substantially space-filling manner in the can and has a radial ignition channel which points to a Mother opens into which an igniter can be screwed in, that the walls of the ignition channel consist at least partially of the lighting kit and that the lid of the can consists at least partially of a material that is combustible or fusible at the combustion temperature of the smoke kit.
  • the ignition of the set takes place by means of an igniter to be arranged on the side of the mist pot through the radial ignition channel, the ignition set and firstly the mist set, usually a hexachloroethane set (HC set), being ignited.
  • an igniter to be arranged on the side of the mist pot through the radial ignition channel
  • the ignition set and firstly the mist set, usually a hexachloroethane set (HC set), being ignited.
  • HC set hexachloroethane set
  • mist pot The advantages of such a mist pot are as follows: The production is simplified since only a single opening for the igniter has to be provided in the jacket wall of the mist pot.
  • the cover of the mist pot the only task of which is to protect against moisture and mechanical stress, is much easier and cheaper to manufacture than before.
  • no opening of the fog pot according to the invention are provided in the lid.
  • the degree of filling of the mist pot according to the invention is significantly higher than in previously known mist pots, since no outflow openings for the mist have to be provided.
  • the burn-off properties are also improved, since by exposing practically the entire filling surface after the lid has melted or burned off, ideal burn-off conditions are created.
  • the mist set with ignition channel and firing set are preferably produced as a pressing body. This improves the burning behavior.
  • the conical design of the mist set makes it easier to remove from a mold.
  • the lid preferably has an inner region made of lead foil coated with a plastic foil. Such a lid is surprisingly robust enough to reliably protect the contents even with larger diameters.
  • the lid has an edge made of sheet metal, which is folded onto the can and has an inner fold in of this edge, by means of which the inner region of the lid is held. This makes it possible to fold the edge area onto the edge of the can together with a sealing ring in a manner known per se.
  • an intermediate block known per se can be provided between the ignition and the fog set.
  • the ignition channel extending from the nut in the wall of the can projects beyond the central axis of the can. This will make him it is sufficient that the focal point of ignition or the distribution of the primer is essentially in the central region of the mist set.
  • a fog set 1 (Fig. 1) is in a can 2, preferably made of tinplate, it consists e.g. from a conventional pressed hexachloroethane batch (HC batch).
  • the mist set 1 rests on the bottom 13 of the can 2, which is connected to the casing wall of the can 2 in a sealed manner by a conventional fold-in.
  • the mist set 1 fills the can 2 up to the lid 6 except for an approximately radially extending release forming the ignition channel 3.
  • an insert nut 14 is located in the jacket wall of the can 2 Shot of an igniter (not shown). The igniter is secured by a removable sealing screw 15.
  • a lighting set 5 and an intermediate set 12 located between this and the HC set are arranged approximately in the middle below the cover 6.
  • the approximately parabolic design of the ignition channel 3 and an essentially concentric distribution of the firing set 5 and the intermediate set 12 can be seen from FIG.
  • the use of the mist pot is produced in a pressing tool, the bottom of which has a core with the desired shape of the ignition channel 3.
  • the firing set 5 is first layered on the core, which does not need to cover the entire core, since it is normally sufficient or even advantageous to carry out an ignition only in the central region of the fog set 1.
  • the mold is filled with the fog set 1 and pressed into a cylindrical body. If necessary, an intermediate sentence 12 can be introduced before the fog phrase 1 is introduced.
  • the insert to be produced can be pressed into a conical body (not shown). After removal from the mold, a compact is obtained which has a groove on the head side which forms the ignition channel 3 and which is at least partially lined with the firing set 5. The compact is then housed in the can 2 and closed with the meltable and / or flammable lid 6.
  • the lid 6 has an inner region made of a two-layer material, e.g. of a lead-polyethylene film, which is held in a fold 11 of the edge 10 forming the outer region.
  • a two-layer material e.g. of a lead-polyethylene film
  • the edge 10 is preferably made of tinplate and with the outer wall of the box 2 connected by crimping and sealing ring between them.
  • a detail of the cover 6 is shown in detail and cross section in FIG. 3, namely a lead film 8 which is directed outwards and a PE film 7 which faces the fog set 1.
  • the edge 10 has the fold 11, in which the layers 7, 8 of the inner region of the cover 6, watertightly sealed, are clamped.
  • a corrugated cardboard layer 16 lies between the HC set and the tinplate wall of the can 2.
  • a holding device 17 is riveted to the can 2.
