Definitions

  • the present invention relates to the field of devices, means and arrangements used for the containment, storage and / or transport of solid, pasty and / or fluid products, generally in medium and large sized containers, particularly refers to a container which circumscribes said product within a flexible bag contained in said container and insulates the product from the container to avoid the treatment, such as cleaning, of the container after emptying and, more particularly, refers to a liquid container flammable which, unlike conventional containers, allows adequate, correct and safe discharge to earth of the static charges that are generated on the surfaces of the container and the fluid, in order to avoid generating potential differences that produce ignitions and that jeopardize the integrity of individuals and the place, particularly when tasks are performed s loading, closing, opening or unloading of containers.
  • medium and large capacity liquid transport containers such as the well-known drums, for example 200 liters, and the IBC (Intermediate Bulk Container) containers, suitable for transporting all types of liquids.
  • Such containers once emptied at the destination of use, must be subjected to cleaning, washing, degreasing, etc., which causes them to be referred to special facilities that must do this cleaning, sometimes within a few hours of emptying, to avoid damaging the container.
  • the task of emptying under certain environmental conditions is added to prevent electrostatic charges generated during transport between the container and the product from producing arcs electrical resulting in the explosion of the container.
  • the generation of electrostatic charges is a natural phenomenon that is related to the atomic structure of matter, whose generation is produced as a result of the relative movement between two surfaces in contact, whether liquid or solid.
  • Static electricity represents a temporary imbalance in the division of charges on the surface of at least two materials that are in contact by electron transfer, thus creating an electric field and a potential difference between them, which can become very high
  • the magnitude of the load depends mainly on the speed of separation and / or friction of the materials and their electrical resistivity.
  • the amount of energy released at the time of the spark is the main factor that determines the danger of a spark, which usually manifests itself in the form of radiation, ionization and heat. Thus, when such electrostatic discharge with spark occurs in a flammable atmosphere, fires occur.
  • ground that is, electrically connect to ground, the medium that contains the fluid or material that is electrostatically charged, making sure that the charges that form can easily dissipate Without causing danger. This can be partially achieved by interconnecting all conductive surfaces on which static electricity can be formed, while the assembly is grounded.
  • the container is grounded, in practice the containers have potential differences between the liquid and the walls of the container, which will remain until the corresponding time of "dissipation" of the loads of the container liquid has elapsed in its entirety.
  • time is not allowed to pass necessary for the loads to dissipate in their entirety, the operator runs the risk of opening the container and that the combustion of the liquid occurs due to the potential difference generated by the spark and the subsequent fire.
  • no type of equipotential or ground connection can avoid this internal surface charge, which can generate, in case of being high enough, a disruptive discharge between the free surface of the liquid and the inner wall of the container, causing serious accidents in the facilities where the container tanks are located.
  • a container for fluid container wherein said container has two side walls, a lower lid and an upper lid provided with at least one fluid loading / unloading mouth, the container being comprised of less an expandable body that is disposed within the container, and which comprises a bottom wall from whose perimeter extend side walls defined by an outer part and an inner part, a neck defined by the extension of the side walls, which is projecting out and beyond the loading / unloading mouth of the container, a discharge means that is in contact with at least a portion of the bottom wall and with at least one of the side walls of the expandable body, being said discharge means project and extend beyond the neck, and at least one linkage means that is mounted in said container loading / unloading mouth and which is in contact with said neck and means of discharge of the expandable body.
