Definitions

  • the invention relates to a gas container, and in particular to a liquid gas container, such as a propane gas container, for use in the home and industry.
  • Liquid gas containers in particular propane gas bottles, are used in many areas of household, trade and industry, for example as fuel gas storage containers. Such gas containers pose a risk of explosion, especially if a gas-air mixture has formed in the area of the bottle and sudden overheating occurs.
  • the invention has for its object to provide a gas container of the type mentioned, which is reliably protected against the formation and spread of flames. And explosions with a simple structure and economical manufacture.
  • This object is inventively achieved in that the walls of the container made of aluminum or an aluminum consisting alloy, and that is arranged in the interior of the container a heat-conducting filling insert made of a metallic spatial lattice that is made of aluminum or an aluminum alloy .
  • the gas container according to the invention consists of aluminum or an aluminum alloy. This eliminates the risk of corrosion potential between the container walls and the thermally conductive filler insert, which according to the invention is arranged in the container and also consists of aluminum or an aluminum alloy, and also largely eliminates the possibility of friction and heat-generating points in the interior of the container.
  • the gas container according to the invention can be used, for example, as a camping gas bottle or fuel gas bottle for burning points in the house stop or used as a liquid gas container for the automotive sector. Due to the filling insert arranged in the interior of the gas container, the heat is dissipated and distributed very quickly over the entire filling insert in the event of heat, thus preventing local overheating and the formation and spread of flames and explosions.
  • the container according to the invention can be produced in a simple and economical manner, for example from sheets, tubes or round blanks. Elaborate and expensive anti-corrosion or anti-friction coatings of the container wall material before the container is assembled, in particular on the inner wall sides, are not required in the container according to the invention.
  • the container according to the invention has a very low weight and is therefore convenient and practical to handle.
  • the gas container according to the invention is advantageously designed such that the filling insert is made of expanded metal.
  • Expanded metal which can be produced in a manner known per se from a metal sheet strip or a metal foil by cutting or punching a plurality of slots of limited length and then pulling the sheet or foil apart in a direction transverse to the direction of the slots lattice-like structure, which has honeycomb-like openings with oblique or vertical to the main plane of the lattice opening walls.
  • Such an expanded metal can, for example, be rolled into a coil or folded into a folding mechanism, individual layers of the expanded metal coming into contact with one another without penetrating into one another. In this way, a spatial network can be formed which has a relatively high inherent stability and shape retention of the individual lattice components, and in which the lattice material itself takes up only a very small proportion of the volume covered by the lattice work.
  • a favorable design of the gas container according to the invention is also given in that the filling insert is made from a mesh.
  • a mesh can be made of wire and can also be combined in a number of layers to form packages and larger spatial structures, even if the individual layers come into contact with each other, they do not penetrate into each other, but form a spatial network that is used for most of its volume is an receptive cavity.
  • a favorable embodiment of the gas container according to the invention is achieved in that the filling insert is designed as a winding.
  • a winding can be made both from an expanded metal and from a mesh.
  • a wrap is particularly suitable as a filling insert for gas containers with a cylindrical interior, for example for propane gas bottles of the commercially available shape. After the roll-up, such a roll has a certain radial compressibility, both when it is wound from expanded metal and when it is wound from mesh.
  • the wrap can be made in such a size that it must be slightly compressed when it is placed in a container in order to fit into the interior of the container.
  • such a wrap After insertion, such a wrap tries to expand a little and then comes to rest against the inner wall of the container and is thus positioned in the container.
  • a wrap can be introduced into an initially open cup-shaped lower part of the container during the production of a gas container, a container cap then being subsequently welded onto the cup-shaped lower part.
  • the filling insert covers practically the entire interior of a container produced in this way and is secured therein against slipping.
  • the gas container according to the invention is advantageously designed in such a way that the filling insert is made of at least two interlocking coils, of which the outer one essentially has the shape of a hollow cylinder, the outside diameter of which is adapted to the inside diameter of the container interior to be filled, and of which the inside diameter are in each case matched to the outer diameter of the respective inner winding which immediately adjoins the inside.
  • the outer wrap is inserted through the top opening of the bottle into the interior of the container.
  • the outer roll which is designed as a hollow cylinder, can be temporarily provided with indentations or gusset folds in order to reduce its outer diameter to such an extent that it fits through the narrow bottle opening.
  • the outer winding automatically returns to its original shape and fills the radially outer regions of the interior of the container.
  • the inner roll the outer diameter of which may, for example, substantially correspond to the diameter of the opening of the bottle-shaped container, is then pushed into the interior of the bottle and there into the cavity of the outer roll.
  • the inner winding can be compressed slightly elastically so that it can be easily introduced into the space in the outer winding.
  • the inner wrap After insertion, the inner wrap then expands again elastically and then comes into contact with the inner area of the outer wrap. If necessary, one or more further inner windings can then be introduced into the first inner wind. Overall, there is a unit forming after the introduction of the winding Filling insert in the container. In this configuration, it is possible to introduce the filling insert even at bottle-shaped containers until the bottle-shaped loading - is already completed container itself. It is not necessary to first insert the filling insert into a pot-shaped lower part of the bottle and then to weld a bottle cap, in which the opening is made, onto the lower part.
  • the filling insert is designed as a folding mechanism.
  • the production of a filler insert by folding a strip-shaped expanded metal or a strip-shaped mesh grid onto one another leads to an essentially rectangular spatial network.
  • Such a structure is particularly suitable as a filling insert for containers with an essentially cuboid interior.
  • a gas container according to the invention is advantageously designed in such a way that the filling insert is arranged in the container and is secured against relative movement.
  • Such an arrangement is given in the configuration of the filling insert as a winding and corresponding dimensioning of the same in relation to the inside diameter of the container interior.
  • a particularly favorable embodiment of the gas container according to the invention is provided in that the expanded metal is produced from a foil made of aluminum or an aluminum alloy with a thickness in the range from 0.02 mm to 0.1 mm, in particular 0.085 mm, by punching and stretching .
  • An expanded metal made of an aluminum or an aluminum alloy in the specified thickness range not only has a particularly low weight, but it also ensures an advantageous honeycomb structure of the individual openings of the expanded metal and sufficient inherent rigidity as well as a certain inherent elasticity of a roll or multilayer structure made therefrom.
  • a spatial network made from such an expanded metal only occupies between 2 and 4% of the volume covered by the network. Such a filling insert thus only insignificantly reduces the usable volume of the gas container.
  • a favorable design of the gas container is also achieved by using AlMgSi1 as the aluminum alloy for the filling insert.
  • This aluminum alloy has proven to be particularly suitable as a material for a heat-dissipating and thus explosion-preventing network in the gas container according to the invention.
  • the gas container according to the invention can also advantageously be designed such that AlMgSi1 itself is used as the aluminum alloy for the container.
  • FIG. 1 shows an exemplary embodiment of a gas container according to the invention designed as a propane gas bottle.
  • the actual container 1 is produced by welding a circular cylindrical pot-shaped lower part to a circular cover part.
  • the walls 2 of the container 1 consist of the aluminum alloy AlMgSi1.
  • At the lower end of the container an annular foot 3 is attached, which is made of the same material.
  • a thermally conductive filler insert 4 made of a metallic spatial lattice, which in the present example also consists of the aluminum alloy AlMgSi1.
  • the spatial lattice work is shown schematically in FIG. 1 by a bevy of oblique lines and essentially fills the interior of the container 1.
  • the lattice work is fixed relative to the container both in the axial and in the radial direction. A relative movement between the container and the filling insert which generates friction cannot therefore take place.
  • the filling insert is designed as an expanded metal coil in the illustrated embodiment.
  • Fig. 3 shows a section of an expanded metal made of AlMgSil, which was produced from a film of 0.085 mm thickness by punching and stretching. The individual honeycomb openings of the expanded metal are visible in FIG. 3.
  • an expanded metal is rolled into a winding 6, the outer diameter of which is dimensioned such that the winding 6 only compresses gently into the initially open pot-shaped lower part the insulating gas bottle can be inserted. After insertion, the wrap 6 elastically expands again in the container and comes into contact with the Inner wall of the container.
  • the height of the winding 6 can be such that it also largely fills the interior of the container in the axial direction.
  • the winding 6 is thus fixed in its position relative to the container and cannot execute any relative movements.
  • the roll 6 of expanded metal forms a spatial lattice work that only occupies between 2 and 4% of the volume over which it extends.
  • the lid can be placed on the lower part and connected to it in a gastight manner by a weld seam running all around.
  • the tightness of the weld seam can be checked in a known manner, for example by means of X-rays or also by means of an endoscope.
  • An endoscope also enables a check of the lattice work installed inside the container.
  • a connection and opening valve 5 is arranged on the top of the container.
  • both the filling insert made of expanded metal and the container itself are made of the aluminum alloy AlMgSil, no corrosion potential can arise between these parts and there is no abrasion. Local warming caused by such phenomena is therefore avoided from the outset. Furthermore, damage to the propane gas bottle by corrosion is prevented.
  • the filling insert acts as a heat-conducting and distributing spatial network, which immediately dissipates any local heat development by dissipating the heat over the entire filling insert area. This makes the filling insert a safety network that prevents and prevents the development of flames and explosions.
  • the propane gas bottle according to FIGS. 1 to 3 has a very low weight and is simple and economical to manufacture and easy to handle. Because of their good Flame retardancy and good explosion protection do not require the installation of pressure relief devices and additional valves next to the connection valve.
  • a removable cover 7 is provided on the upper part of the propane gas bottle, which is indicated in broken lines in FIG. 1.
  • the filling insert is made up of two coils of expanded metal arranged one inside the other.
  • the material of each of these coils corresponds to the material of the material specified in the exemplary embodiment according to FIGS. 2 and 3.
  • the outer winding 8 (FIG. 4) and the inner winding 9 (FIG. 5) are each manufactured individually.
  • the outer diameter of the outer coil is adapted to the inner diameter of the container to be filled by the filling insert so that the outer coil, after being introduced into the container, lies against the inner wall of the container with a certain intrinsic elasticity.
  • the hollow cylindrical outer wrap Because of the relatively small “wall thickness" of the hollow cylindrical outer wrap, it can also be introduced through relatively narrow openings, such as the opening 11 of the bottle 12 (FIG. 6), the cylindrical wrap being temporarily deformed by bending or folding using its own elasticity and is reduced in its outer diameter so that it can be inserted through the opening 11 into the interior of the bottle 12. As soon as the outer roll 8 is in the interior of the bottle 12, it assumes its cylindrical shape again under its own elasticity and expands again so far that it comes to rest on the inner wall of the bottle 12. The inner wrap 9 (FIG. 5) can subsequently be introduced into the bottle 12 through the opening 11. The outside diameter of the inner winding 9 is adapted to the inner diameter of the outer winding 8.
  • the inner diameter of the inner wrap can be reduced to such an extent that it can be inserted through the opening 11 of the bottle 12 into the interior of the outer wrap 8.
  • a hollow tube 13 of small diameter can be provided in the center of the inner winding 9.
  • a test tube or a dip tube can be inserted into such a cavity.
  • both coils are hergestllt from the managerial g chen aluminum alloy AlMgSi1 8 and 9, showing also the walls of the bottle 12 are formed do not generate between the two winding of the filling insert or between the filling insert and the container corrosion potentials.
  • Both coils 8 and 9 consist of expanded metal made of an AlMgSi foil of 0.085 mm thickness.
  • FIG. 7 shows a container according to the invention designed as a fuel gas tank for motor vehicles.
  • 7 has a substantially cylindrical shape.
  • the filler insert of this container can consist of a wrap made of expanded metal.
  • the container itself can be formed from two pot-shaped parts welded together.
  • the expanded metal coil which is designed in its diameter, that it can be introduced into the interior of the container with slight deformation, first inserted into a pot-like part of the container.
  • the other pot-like part of the container is then pushed over the free-standing end of the coil until it comes into contact with the other pot-like part, after which the two pot-like parts are welded around the circumference at their abutting edges.
  • the cylindrical container is then completely filled by the filling insert designed as a winding.
  • the aluminum alloy AlMgSil is an advantageous material for both the winding and the walls of the container.
  • the coil can be made of expanded metal from a foil of 0.085 mm thickness.
  • the length and diameter of the cylindrical LPG tank depend on the required tank capacity. For example, the length can be approximately 1200 mm and the outer diameter can be, for example, 200 to 300 mm.
  • Gas containers according to the invention can be produced in different shapes and for a large range of capacities and can be used to store a large number of gases or liquid gases or flammable liquids. In addition to the storage of propane, storage of butane or methane can also be considered.
