Definitions

  • the invention relates to the field of fire extinguishers. More particularly, the invention relates to an extinguisher comprising a cylinder adapted to contain a fire extinguisher, means for releasing the extinguishing product from the cylinder and comprising at least one compressed gas cartridge, at least two tanks each capable of containing at least one additive product, and means for releasing the at least one additive product from the at least two reservoirs and for mixing it with the extinguishing product during the release of the extinguishing product.
  • the invention also relates to fire extinguisher cartridges and the use of such cartridges.
  • extinguishers exist on the market. They can be classified according to the type of extinguishing product they use: water extinguisher, foam, powder or gas (carbon dioxide). The use of one type of extinguisher over another depends essentially on the burning material. Water extinguishers are used for class A fires, foam and gas fire extinguishers for class A or B fires. Powder fire extinguishers can be used for class A and B, AB and C, or D. The formulations present in the fire extinguisher also vary depending on the type of fire extinguisher.
  • Known extinguishers comprise a reservoir, for example a cartridge, containing all the additive products. This one is usually arranged inside the bottle.
  • fire extinguishers containing several additive chambers have been described.
  • an extinguisher comprising a percussion head and a protective tube in which is arranged a gas capsule and two additive receiving chambers permanently attached to the protection tube.
  • the additive receiving chambers are not accessible independently by the user.
  • EP 1 935 458 a fire extinguisher consisting of two outer tanks attached to the body of the fire extinguisher cylinder. This configuration requires the use of numerous connectors to connect the additive compartments, the compressed gas cartridge and the interior of the cylinder.
  • Additive cartridges in fire extinguishers have an expiry date. In the majority of cases, they have not been used before this expiry date and must therefore be changed. The unused cartridges are burned without establishing a recycling scheme or specific treatment of the additives present in said cartridge. However, some of said additives are polluting or dangerous for the environment. The recycling of these known cartridges, or their contents, is not easy considering their configuration or their location vis-à-vis the bottle extinguisher. The change of these cartridges can therefore be dangerous and expensive. There is a need for an extinguisher for better recycling of the cartridges containing the additives.
  • the invention proposes to overcome the disadvantages mentioned above while retaining the advantages of known cartridges.
  • the present invention provides an extinguisher comprising at least two tanks each capable of containing at least one additive product and means for releasing the at least one additive product from each of the at least two tanks, and characterized in that at least one of the tanks is removable from the fire extinguisher.
  • the term "at least one "tank” is considered to include, in particular, the terms “one or more tanks” and "a plurality of tanks”.
  • said at least two tanks are removable relative to the fire extinguisher.
  • the term "removable from fire extinguisher” means that the tanks may be detached or removed from the fire extinguisher to form a separate, separate or disjointed element from the fire extinguisher.
  • At least two tanks is considered to include, in particular, the terms “two or more tanks” and "a plurality of tanks".
  • the presence of several reservoirs each able to contain one or more additives makes it possible to partition the additives in the different reservoirs.
  • the different tanks can be filled according to the subsequent purpose sought from a point of view of the recycling or treatment of said additives.
  • one or more additives classified as highly polluting for the environment and which can be treated or recycled separately according to the same procedure may be placed inside a first reservoir.
  • a second tank may for example contain one or more non-polluting additives and not requiring treatment or recycling.
  • the additives in the different tanks can also be separated according to their chemical structure, for example separating the fluorinated additives and the non-fluorinated additives, or separating the long-chain hydrocarbons from the shorter-chain hydrocarbons.
  • the presence of tanks having a removable relative to the fire extinguisher makes it possible to extract or remove the tank or tanks from the extinguisher and to treat them individually according to a precise recycling scheme.
  • the tanks containing the additive products can thus be directly accessible to the user responsible for controlling the proper functioning of the fire extinguisher.
  • the at least two reservoirs are disposed inside the cylinder.
  • the arrangement of the tanks inside the cylinder facilitates their use in several types of fire extinguisher. This embodiment avoids the use of complex connection between the tank and the extinguishant product.
  • said at least two tanks are disjoint.
  • tanks can be treated or recycled independently one of the other. For example, if one of the tanks contains an additive product with an expiry date that is shorter than that of the additive product contained in the second tank, only the tank with expired contents may be removed from the fire extinguisher.
  • the at least two tanks are provided with means to be interconnected by their end or by their side wall.
  • the tanks can be interconnected and grouped in a small space of the fire extinguisher.
  • the mixture between the additives and the extinguishing product will be more homogeneous.
  • this embodiment will facilitate the gripping of all the tanks and their subsequent separation.
  • At least one of the tanks has a side wall connected to another tank, preferably to the side wall of another tank, more preferably at least one of the tanks has a side wall at least partly common with a side wall of another tank.

  • at least one of the tanks is removable relative to the cartridge.
  • the term "removable relative to the cartridge” means that the reservoir can be detached or removed from the cartridge to form a separate, separate or disjoint element of said cartridge.
  • said tanks are fixed relative to the cartridge.
  • said tanks may have a side wall or upper at least partly common to that of the cartridge. This alternative configuration also makes it possible to provide separate tanks whose lower opening is accessible directly to a user wishing to remove or modify the contents of the tanks or to fill them with a solution of freshly prepared additive products.
