Definitions

  • the invention relates to a storage container for liquid and / or solid chemical precipitants, which consists at least on the inside of its walls from material resistant to these.
  • Storage containers of this type are known, which consist of high quality metal alloys, as such
  • Alloys have the property of being resistant to chemical precipitants and also have the necessary strength for the construction of containers.
  • This type of container is relatively expensive and difficult to adapt to the often specified geometry at the installation site.
  • Such known storage containers consist of a
  • glass fiber reinforced plastic layer on spacer heltern is applied from aluminum ribs.
  • the object of the invention was therefore to provide storage containers which are simple and inexpensive to manufacture, to which the often predetermined geometry can be easily adapted and which moreover take account of the constantly increasing need for security.
  • the material of the walls of the storage container consists at least partially of a low-pressure polyethylene layer and that on this layer a further polyethylene layer, preferably provided with knobs on one side, is provided lying on the knobs side.
  • the pimpled cover ensures that between two polyethylene layers in a simple manner
  • Cavity is created which, in the event of a leak in the first film, on the one hand securely stores the leakage liquid and on the other hand creates the possibility of detecting the leakage using measuring devices.
  • the walls which also means the bottom of the storage container, are according to the training of
  • Invention can be designed in many ways.
  • a special embodiment according to the invention can be seen in the fact that the walls of the storage container consist entirely of low-pressure polyethylene.
  • the walls of the storage container from any solid

  • the Walls of the storage container made of any solid support material with an inner one, provided with knobs on one free side
  • Polyethylene layer exists.
  • Another solution consists in that the walls of the storage container consist of a hardenable carrier material with a studded polyethylene layer on the knob side, and that the knobs are embedded in the hardenable carrier material.
  • the need for security is met in that the cavity formed by the knobs of the further polyethylene layer resting on the walls of the storage container is hermetically sealed and connected to a vacuum monitoring device.
