Definitions

  • the present invention relates to the field of tanks and more particularly those intended for transporting cryogenic liquids by semi-trailers, trailers, carriers and wagons, or even by containers or swap bodies.
  • cryogenic liquids because of the temperature difference between the transported liquid and the ambient air is often of the order of 200 ° C, which requires thermal insulation of the tank.
  • the traditional solution for insulation is made by polyurethane materials or other combustible materials, however these are forbidden by ADR (A greement for the transport of goods D anger recipients by R oute) for products to - below -182 ° C.
  • the other solid materials, such as perlite, for the same insulation performance often require a greater thickness, hence a greater total mass. Given the limit of the total authorized rolling mass, any additional mass consequently leads to a reduction in the mass of transportable product. Even for light products such as methane, too thick insulation would exceed the authorized road clearance.
  • a device consisting of two fixed studs and two movable studs arranged in the lower part.
  • the pads consist of a stack of welded cones to limit conduction.
  • the resistance over time is not controllable.
  • the object of the invention is to respond to these problems and to guarantee reliable maintenance of the inner tank while allowing recovery of the longitudinal expansion, in particular for tanks installed on semi-trailers, trailers, carriers, wagons, containers or swap bodies.
  • the cryogenic liquid transport tank comprises an inner tank, of substantially cylindrical shape, arranged in an outer casing, the inner reservoir and the outer casing are coaxial with axis X, said inner reservoir being connected to the outer casing by a support device, it is characterized in that the support device consists of a single cone of axis X located in the center of the tank and connecting the inner tank to the outer casing.
  • the support device consists of a single cone of axis X located in the center of the tank and connecting the inner tank to the outer casing.
  • the cone comprises a base and a top, the top being fixed to the center of the inner reservoir.
  • the base will preferably be placed behind the top, above the running gear of the tank to take up the forces.
  • the tank comprises pipes for filling the tank in the center of the tank.
  • the pipes are thus arranged close to the fixed part of the reservoir and are therefore little affected by the contraction of the reservoir.
  • this position of the cone limits the differential expansions and the stresses in the inter-wall piping, because, in effect, the further the drainages are from the fixed point, the more they are subjected to the contractions of the wall of the tank.
  • the cone has holes. They make it possible to limit the thermal flows between the inner tank and the outer casing while reducing the weight of the tank.
  • the cone is fixed by welding.
  • the cone has a length greater than 400mm, preferably 500mm. This makes it possible to limit the heat flow between the tank and the casing.
  • the cone will preferably have a length of 1.10m.
  • the cone has a wall thickness of between 3 and 10mm.
  • the thickness of the cone must guarantee sufficient strength of the inner tank.
  • the tank is a semi-trailer.
  • the outer casing consists of two parts each with a half-shell and a bottom.
  • the assembly of the reservoir in the casing is thus easier, each part being less heavy to move than the complete casing.
  • a first part of the outer casing is longer than a second part. This in the case where the base of the cone is offset from the center of the tank.
  • the assembly can be done horizontally or vertically.
  • the front corresponds to the front 10 of the tank 1 on the coupling side and the rear to the rear 11 of the tank 1 where the wheels 5 of the semi are located. -trailer.
  • the tank 1 is a cylindrical double-walled tank consisting of an inner tank 2 and an outer casing 3, the assembly is oriented along a substantially horizontal axis X.
  • a cone 4 is fixed to the center 12 of the tank 1 between the tank 2 and the casing 3.
  • the cone 4 comprises a base 40 and a top 41.
  • the base 40 has a larger diameter than the top 41.
  • the base 40 is connected to the casing 3 and offset towards the rear of the tank 1, while the top 41 is connected to the center of the tank 2.
  • the middle of the cone is disposed at the center 12 of the tank or that the base 40 is fixed to the center 12 of the tank 1 without departing from the scope of the present invention.
  • the cone 4 being connected in a fixed manner between the tank 2 and the casing 3 next to the pipes 6, it makes it possible to limit as much as possible the stresses in these pipes 6 during the expansion of the tank 2.
  • the base 40 being connected near the running gear 5, it facilitates the recovery of loads from the tank 2.
  • the cone 4 is pierced with bores 42 in order to lighten it and to limit the thermal conduction between the inner tank 2 and the outer casing 3.
  • the bores 42 are round and of identical size but they could be of shape and size. different.
  • the tank 1 has a space between the walls of the tank 2 and the casing 3. When loading the cryogenic liquid into the tank 2, the latter will retract due to the cold while the casing 3 will remain at ambient temperature. and keep the same dimensions.
  • the inner tank 2 being fixedly connected to the outer casing 3, the space between them will increase, but as only the central part is fixed, the movement of the ends will have no effect on the casing 2 or on the piping 6.
  • the outer casing 3 consists of two parts 30 and 31 each with a half-shell, respectively 300 and 310, and a bottom, respectively 301 and 311.
  • first part 31 of the casing 3 is longer than the second part 30.
  • This first part 31 is, in the example illustrated, arranged at the front 10 of the tank while the second part 30 is arranged at the 'rear 11.
  • the top 41 of the cone 4 is placed in the center of the tank 2, therefore the base 40 is offset from the center 12 of the tank 1.
  • the two parts of the casing 3 are therefore of sizes different.
  • the middle of the cone 4 is at the center 12 of the tank, its base 40 and its top 41 are arranged symmetrically with respect to this center 12 and the two parts 30 and 31 of the casing 3 are the same size.
  • the assembly can be carried out flat (horizontally) or vertically without departing from the scope of the present invention.
  • the advantage of having an envelope in two parts is that these two parts are easier to handle whatever the chosen assembly.
