Definitions

  • the present invention relates to an improved arrangement for destruction of ammunition and ammunition components with limited inherent explosive force inside a detonation-proof chamber intended for this, which on the one hand screens the destruction process from the environment and on the other hand makes it possible separately to retain and clean the explosion gases formed during the combustion, deflagration and/or detonation of the explosive substances included in the goods for destruction.
  • the destruction process itself is based on the explosive substances included in the goods for destruction being, by indirect heating, provided with a sufficiently high temperature in order to be combusted, to detonate or to deflagrate.
  • a destruction arrangement of this particular type must be robust and capable of being manufactured at as low a price as possible at the same time as it is a significant advantage if it can be made mobile and can easily be transported to the place where the ammunition is located so that transporting old, unsafe ammunition over long distances is avoided.
  • the arrangement according to SE 9403528-4 thus describes a destruction arrangement for treatment i.e. destruction of ammunition and ammunition components with limited inherent explosive force, which in principle concerns ammunition up to approximately 60 mm calibre.
  • the arrangement in question comprises a ball-shaped inner detonation or destruction chamber which is dimensioned so as to stand up to the detonations which the goods which are to be destroyed in the same might give rise to.
  • the detonation chamber is in turn rotatably arranged inside a heat-insulated outer chamber, in which burners for external heating of the detonation chamber are also arranged.
  • a sand layer is then arranged, which, through the external heating of the chamber together with the radiant heat, rapidly provides the ammunition components introduced into the chamber with such a high temperature that explosive substances included in them are ignited and combusted, detonated or deflagrated.
  • the advantages of the sand layer are firstly that the heat transfer to the ammunition components introduced is very effective and also that it functions as a heat accumulator and retains and stores the heat which is formed during the combustion, detonation or deflagration of the explosive substances in question.
  • the sand layer therefore has a number of advantages, it also has the disadvantage that it takes up space and therefore increases the requirement for available chamber volume at the same time as the previously mentioned chamber equipment, which makes it possible to empty the scrap out of the chamber but keep the sand, is expensive to manufacture on the one hand and on the other hand restricts the life of the chamber because it is not possible to avoid it being gradually damaged.
  • the aim of the present invention is to provide an arrangement which can solve the same problem as our earlier ammunition destruction arrangement described in the abovementioned patent application but which can be manufactured at a considerably lower cost.
  • a further advantage which this basic shape provides is that the chamber volume in the downwardly facing tip of such a chamber is very concentrated and we have now been able to establish that, thanks to the very good heat transfer obtained in this case in this part of the chamber via radiant heat and via direct transfer through the chamber wall, we can provide the goods for destruction inside the chamber with the high temperature which is required for ignition of all types of explosive substances which may be involved.
  • this type of chamber it has therefore been possible for us completely to dispose of the sand layer and the chamber equipment previously necessary for its maintenance. When the destruction process is then m full-scale operation inside the chamber, the gradually formed scrap layer then takes on the role of the sand as heat accumulator.
  • Fig. 1 shows a sectioned longitudinal projection with the inner destruction chamber in the filling/destruction position
  • Fig. 2 shows a sectioned lateral projection of Fig. 1 along the line I-I
  • Fig. 3 shows the same projection as Fig. 2 but with the inner destruction chamber m the emptying position.
  • the destruction arrangement thus comprises a heat-insulated outer chamber 1 suspended m a stand 2 which is only drawn in part in the figures.
  • the outer chamber 1 can be rotated about the horizontal axis 3 by means of rollers fixed m the stand which are not shown in the figures.
  • a burner 4 for heating the interior of the chamber and the inner destruction chamber 6 suspended therein.
  • a gas outlet 5 for the combustion gases generated in the oil or LPG burner 4.
  • the inner destruction chamber 6 has the shape of two identical frustocomcal gable pieces 9 and 10 which face away from one another with their tapering parts and which between them have a cylindrical intermediate part 11
  • the chamber is constructed in two parts which are joined together with one another.
  • the dividing line between them runs along tne line 12 along a central dividing plane through the cylindrical part
  • the joining-together between the parts has, as shown in the figures, been effected by means of flanges arranged on the parts and a joint band 15 holding tne flanges 13 and 14 together
  • This basic shape gives the inner detonation chamber 6 great resistance to internal detonations but is at the same time relatively easy to manufacture and it is or parts of it are therefore easy to replace.
  • the stresses are m fact very great on a destruction chamber of this type and it is therefore essential to be ready to replace the same after a relatively long period of continuous operation.
  • the previously mentioned inlet/outlet 7 consists of a first pass-through part 17 in which an openable and closable detonation closing hatch or lock hatch 18 is arranged. Detachably connected to this pass-through part is a second lock part 19.
  • the latter part comprises a second openable and closable closing hatch 20 and also a container 21 designed for goods for destruction in a suitably adapted quantity.
  • the ammunition components which are to be destroyed are introduced into the destruction chamber 6 batchwise from container 21 at a rate adapted to the material and the capacity of the arrangement.
  • the burner 4 acts on the outside of the chamber 6.
  • Explosive substances included in the ammunition components are combusted, detonated or deflagrated and metal parts involved gradually form a broken-up scrap. This forms a scrap layer in the interior of the chamber 6 which, as it grows, becomes an increasingly effective heat accumulator for all the heat which is formed during combustion of the explosive substances.
  • the supply of external heat is therefore adjusted according to the need to heat the chamber.

Abstract

L'invention concerne un dispositif permettant de détruire des munitions et des composants de munitions, et de transformer ces articles à détruire en mitraille prête à être réutilisée. Selon le procédé, on introduit les articles à détruire dans une chambre de destruction (6) configurée d'une manière particulière, dans laquelle on les chauffe à une température qui permet de faire brûler, détoner ou déflagrer les substances explosives qu'ils contiennent. La chambre est chauffée par des brûleurs (4) disposés à l'intérieur, et la mitraille (22) restant des articles qui y ont été précédemment détruits sert d'accumulateur de chaleur pour retenir la chaleur libérée durant la destruction des articles explosifs. Une caractéristique de la chambre de destruction (6) est qu'elle a la forme d'un cône double (9, 10) avec une partie intermédiaire cylindrique courte (11) disposée entre les bords de la base des cônes. L'un des avantages de la présente construction est que la forme particulière de la chambre de destruction rend sa fabrication relativement facile, en même temps qu'elle contribue activement à l'obtention de températures élevées qui lui donnent une bonne capacité de traitement.
