Definitions

  • the invention relates to a tank system, in particular for storing and dispensing liquid fuels with a closed liquid tank accessible via an opening and with devices for filling the tank and for removing liquid stored therein.
  • Such tank systems are typically part of a gas station for refueling of motor vehicles or tank farms.
  • a gas station ver ⁇ usually adds several such tank systems and indeed one of the number of offered fuels corresponding number.
  • the liquid tanks are typically installed in the soil, whereby special precautions have been taken to ensure that the environment of a liquid tank does not have groundwater accessibility. Also above ground fluid tanks are known. In accordance with the safety regulations, the liquid tanks are double-walled.
  • Such liquid tanks typically have a dome through which the fittings are led out.
  • These valves are spielnem a filling tube, a sampling tube, a vent tube and a direction finder and safety equipment, which can be provided as a safety orientation, for example, a limit sensor.
  • the dome itself is closed at the top by a closure plate. This likewise constitutes an inspection opening.
  • the closure plate is connected to the dome by means of a flange connection.
  • the closure plate carries the connections for the supply lines on the top side.
  • This tank system is characterized by the fact that an existing liquid tank with its safety and environmental suitability is used in order to arrange one or more individual and separate tank inner containers in it.
  • the useful volume of the liquid tank is reduced by the volume of the or - tank inner container.
  • the inner tanks of the tank are made of a flexible casing, for example a fabric or fiber-reinforced plastic, the entire original useful volume of the liquid tank for a liquid, for example a fuel, can nevertheless be used if necessary in the case of emptied or emptied tank inner containers. Only when the tank inner container or containers are also filled, the useful volume of the liquid tank is reduced by the volume of Tankinnenbe ⁇ container.
  • the useful volume of the liquid tank can vary. This allows adaptation of the use of the useful volumes provided by the tank system to suit the needs, with the result that, in the installation of a flexible tank inner tank, the useful volume of the liquid tank is not necessarily reduced by the maximum volume of the tank inner tank (s).
  • the tank inner container will be used for storing additives, for example aqueous urea solution, as the Reducing agent is required for Entsticken diesel engine exhaust. Due to the preferably flexible nature of the tank inner containers, the respective useful volumes can be adapted to the throughput achieved. For this reason, the tan inner container (s) will be rather larger in terms of their respective useful volume than actually required at the time of planning. Partial filling of the tank inner tank (s) is readily possible. Dement ⁇ speaking then the useful volume of the outer liquid tank is greater.
  • Each tank inner container has its own filling, extraction and vent lines, which are also suitably guided to the dome of the liquid tank and led out of this top side.
  • a filling line or a withdrawal line can consist of a dimensionally stable, flexible hose, which connect the tank inner container with connections on the dome of the liquid tank.

  • a support tube can also be used in a tank inner container, which is arranged in the region of the end remote from the dome of the liquid tank and thus not suspended from the dome or its closure plate. It is then only necessary to ensure that the support tube remains vertically aligned, independently of the filling state of the tank inner container, due to the level detection probe arranged in the support tube.
  • the support tube can also be suspended from the ceiling of the tank of liquid surrounding this tank. Then the support tube does not need to be on the bottom side in contact with the shell of this tank inner container.

  • the determination of a flexible shell as tank inner container takes place according to a preferred embodiment only in the region of the sole of the inner wall of the liquid tank, so that on the determination of Tan ⁇ inner container of the tank, the Gearge ⁇ weight of the tank inner container does not have to be collected.
  • the flexible casing of such an inner tank of tank can carry buoyant bodies in the region of its upper end, by which the inner tank of the tank is arranged with its upper side in a horizontal arrangement corresponding to the liquid level within the liquid tank.
  • Such limit switches can also be arranged in floating bodies within the inner tank of the tank.
  • an outer frame can be used. This is preferably articulated in the vertical direction, so that the frame does not have to absorb the weight of the filled tank inner container. In principle, however, it is also possible to do something in other directions.
