Definitions

  • the present invention relates to a flexible tank used for transportation and/or storage of liquid fluids of any kind, and more particularly to a flexible tank that provides the elimination of the components supporting the tank (i.e. bulkhead) at the region corresponding to the door of a vehicle transporting said tank, and the reduction of the liquid wave within the tank due to forces resulting from the vehicle's transportation conditions.
  • the feature that the flexible transportation tank shows an adequate resistance against the internal liquid pressure and against external strains is one of the significant design criteria that should be considered.
  • transportation tanks made from flexible materials are placed into containers which have rigid walls and are typically positioned on the rear part of vehicles such as trucks, TIRs, etc. for transportation purposes.
  • liquid material within the tank can freely move to any direction so that once the door of the container is opened, the liquid tends to flow towards this free direction, this fact resulting in accumulation of stresses on connection points or surfaces of the flexible tank and forces the structural strength of the same.
  • a set i.e. bulkhead
  • the present invention provides a flexible tank, having a closed form, and in which liquid is stored and transported from one location to the other by means of a vehicle, characterized in that the tank is separated to include plurality of partitions allowing liquid transfer between at least two partitions.
  • one entrance partition is formed close to the door of the container carrying the flexible tank, and an main partition is provided in connection with said entrance partition.
  • a large surface having holes on itself of varying sizes is provided between the main partition and the entrance partition to ensure a controlled liquid transfer.
  • this transfer area can also be formed as a baffle element.
  • valve hole region whereby liquid is inlet into (or outlet from) the tank is closed by means of a protective cover in order to provide tank's hygiene.
  • Figure 1 illustrates a side view of the flexible tank in a container.
  • Figure 2 illustrates a front view of the flexible tank in a container.
  • Figure 3 illustrates a front view of the transfer surface of the flexible tank in a container.
  • Figure 4 illustrates a view of the cross-section A-A indicated in Figure 3.
  • Figure 5 illustrates a view of the cross-section B-B indicated in Figure 3.
  • Figure 1 provides a side view of the flexible tank in a container (1).
  • the term "container” (1) will refer to a carrier means adaptable to any kind of land, air, and marine vehicles, or to an embodiment functioning as the carrier body of such vehicles.
  • the flexible tank comprises an entrance partition (3) positioned close to the doors (12) of a container, and a main partition (2) that is in connection with this entrance partition (3).
  • the entrance partition (3) is preferably smaller than the main partition (2) with respect to its volume and with respect to its height. In this preferred embodiment, no bulkhead is used in connection to the container on the surfaces of the entrance partition (3) being close to the container doors (12).
  • the flexible tank is formed from four inner layers (5) each with an approximate 125 micron thickness and an outer layer (4).
  • the inner layers (5) are preferably made from a plastic- based material and particularly from a thermoplastic material (such as PP, PE, PVC, nylon ® ), whereas the outer layer (4) is made from those materials used in producing big bags.
  • the flexible tank can also be formed with more or less than four layers, and if a single layer is to be used, a material with a thickness of around 1000 microns may be utilized.
  • a transfer surface (10) is provided between the entrance partition (3) and the main partition (2).
  • the transfer surface (10) contains various numbers of holes of different sizes along its thickness.
  • the transfer surface (10) is preferably obtained by interconnecting/welding together the entrance partition (3) and the main partition (2) (preferably interconnecting the inner layers thereof) and by producing holes (6) on said interconnection/welding surface (10). It is hereby aimed to control the rate of liquid transfer from the entrance partition (3) to the main partition (2) (or vice versa) and any liquid pressures to form. For instance, when the container doors (12) are opened as the tank is filled; the reaction force of the transfer surface (10) shall avoid the instant liquid flow tendency from the main partition (2) into the entrance partition (3).
  • the transfer partition (3) can also be positioned between the entrance partition (3) and the main partition in the form of a baffle element, as an external element, containing holes in itself.
  • preferably stripe-like support elements (8) can be provided, which extend vertically and are fastened by their ends to the outer layer (4) in order to enhance the strength of the transfer surface (10) that becomes stressed due to the liquid moving in the flexible tank.
  • Said support elements (8) are preferably welded to the layers on the transfer partition (10) or are interconnected by any other convenient method known in the relevant art.
  • the edges of holes (6) at the transfer surface (10) are also interconnected by means of welding (11).
  • the entrance partition (3) contains a valve (7) for liquid inlet into the flexible tank. Once the tank is filled, the valve (7) is covered by a protective cover (9) that is preferably connected to the inner layer (5) for providing isolation from the exterior.
  • the protective cover (9) is fastened as illustrated in Figure 5.
