Definitions

  • the invention relates to a device for storing a fluid, comprising an outer container and an inner container arranged in the outer container for receiving the fluid, the inner container being made of stainless steel, the outer container being made of a non-corrosive material other than stainless steel and the outer container with the inner container arranged therein is at least partially arranged in the ground.
  • the "drinking water tank 10000 liters made of stainless steel" offered and described in the webshop of the UdoJenfels trading agency is installed underground and is made of INOX stainless steel.
  • the drinking water tank consists of a container and has an inner layer and an outer coating.
  • the outer coating consists of a glass fiber reinforced plastic.
  • the object of the invention is to provide such a device for storing a fluid, for example drinking water, which protects the device from mechanical damage and at the same time enables a cost-effective construction.
  • a device for storing a fluid comprising an outer container and an inner container arranged in the outer container for receiving the fluid, wherein the inner container consists of stainless steel, the outer container consists of a non-corrosive material different from stainless steel, the outer container with the inner container arranged therein is at least partially arranged in the ground and the inner container is dimensioned such that it would not be load-bearing in the ground without the outer container, so that a device that is load-bearing in the ground is achieved only through the combination with the outer container.
  • the fact that the inner container is dimensioned in such a way that it would not be load-bearing in the ground without the outer container means that the inner container would not be able to withstand the forces acting on it due to the soil surrounding it or the device due to its dimensions alone.
  • the inner container can therefore also be just a stainless steel inner lining or a stainless steel inner coating of the outer container, for example.
  • the outer container can be alone in the ground.
  • the outer container is also dimensioned in such a way that it is not load-bearing on its own in the ground, and the dimensioning of the inner container and the dimensioning of the outer container are selected such that they are only joined to one in the Earth-bearing facility leads.
  • the outside of the inner container rests directly on the inside of the outer container and the outer container is designed in such a way that it itself serves to provide mechanical protection and / or to isolate the inner container.
  • the inner container and the outer container are arranged at a distance from one another, so that there is an intermediate space between the outside of the inner container and the inside of the outer container, one for mechanical protection and / or for insulation of the inner container Has container designed filling.
  • the force-resistant properties of the outer container can be combined with the hygienic properties of the stainless steel container.
  • An insulating layer between the containers can increase the stability and at the same time enables an even better insulation of the inner container than in the case of designs in which the containers fit tightly against one another.
  • a plastic material is being used, it is preferably polypropylene and / or polyethylene, but otherwise, of course, any other sufficiently stable plastic is also meant.
  • the advantages of a container made of a plastic material include above all malleability, hardness, elasticity, breaking strength, temperature and heat resistance and chemical resistance.

This saves material costs and weight of the container. In addition, according to a preferred development of the invention, it is provided that the inner container consists entirely of stainless steel.
  • the space between the inner container and the outer container has a width of> 1 cm, preferably> 4 cm, very particularly preferably> 10 cm.
  • a filling is preferably arranged, which serves to protect against mechanical damage by external forces and / or serves to isolate the inner container and its contents.

  • the filling of the space can have different materials and shapes.
  • the filling of the space has an insulating foam comprising polyurethane.
  • the insulating foam has the advantage that it has a high insulating capacity, since the heat conduction of polyurethane foam is very low. It is therefore used in particular to isolate the inner container.
  • the filling of the gap comprises at least one spacer, the spacer preferably comprising a plastic material or metal material and being designed such that the inner container can be positioned immovably in the outer container in the radial direction.

  • a homogeneous plasticized tape is spirally wound onto an inner core, which is preferably designed as a steel core and is removed again after the tube has been produced.
  • the turns of the tape are connected to one another by overlaps so that they ultimately form the winding tube.
  • Due to the solid inner core used in the manufacture of the winding tube a constant inner diameter is given even with different wall thicknesses or loads.
  • the wall thicknesses and gradations are designed and manufactured individually according to the operating conditions.
