Conte,
  • This invention relates to a double-walled container having an evacuated space in between which is adapted to be provided with a thermal insulating system including insulation material, reflective barrier layers and heat conductive shields, and it relates more particularly to an insulated container of the type described which is adapted for use with material having a temperature that differs widely from the temperature adjacent the outer wall of the container.

  • a low boiling liquefied gas such as helium, neon, hydrogen and the like
  • the container of this invention finds equal use in the storage and transportation of other low boiling liquefied gases such as liquefied oxygen, nitrogen, methane, LNG, ammonia and the like, or for use with fluids at high temperature, such as in the storage or transportation of molten metal or in the housing of sodium or potassium for power cell conversion and the like.
  • insulated containers have been proposed for storage and transportation of low boiling liquefied gases.
  • such containers are formed with an inner vessel for housing the liquefied gas and an outer vessel which surrounds the inner vessel with a spaced relation in between to provide an intervening insulated space which is preferably, though not necessarily, maintained under vacuum.
  • An insulation system composed of multiple layers of a low conductive material, with an occasional heat reflective barrier sheet, is disposed within the intervening space with the layers disposed generally parallel to the walls of the vessel so as to extend normal to the direction of heat flow between the walls.
  • a fluid conduit in the form of a neck tube, extends vertically from the inner vessel through the top of the outer vessel for communication with the interior of the inner vessel for the passage of liquid and gases into and out of the container.
  • the neck tube serves to support the inner vessel while the insulation system provides lateral support, while in other containers, the neck tube does not serve to support the inner vessel but nevertheless is interconnected both with the inner vessel and the outer vessel.
  • axially spaced apart disc members are secured to the outer wall of the neck tube.
  • the layers of insulation material, including the occasional radiant heat barrier layer are wrapped, preferably spirally, about the innermost vessel to a desired thickness, corresponding to the level of a first disc member.
  • a shield of conductive metal such as copper or aluminum, is installed about the built-up insulation with an overlap onto the disc to which it is secured by a soldering or other metal bonding means to provide a connection of low thermal resistance or of high thermal conductivity for transfer of heat from the shield to the disc and neck tube.
  • the operations are repeated serially until the insulation system with the heat conductive shields has been installed.

  • FIG. 4 is a top plan view of disc members employed in the support means for the neck tube.
  • the insulated container is formed of an inner vessel 12 and an outer vessel 14 with an insulated space 16 in between, said space preferably being an evacuated space.
  • the inner vessel is preferably supported by a hollow fluid conduit, hereinafter referred to as a neck tube 18, secured to the top of the inner vessel by means of an adaptor 20 for communicating the interior of the inner vessel with valve means (not shown) beyond the outer vessel.
  • the portion of the neck tube 18, disposed in the space between the inner and outer vessels, is provided with a plurality of ring members 32 of highly conductive material, which are joined to the outer wall of the neck tube portion in axially spaced apart relation.
  • the metal ring members may be spun onto the neck tube prior to assembly, or the ring members can be provided in the form of metal disc members having a central opening corresponding to the outer wall to wall diameter of the neck tube and to which the ring members are secured by a metal bonding means, such as silver soldering 34 and the like, in the desired axially spaced apart relation.
  • the neck tube and ring members can be molded as an integral unit.
  • plastic such as carbon filled plastic, ceramic filled plastic, or of such plastic materials as Teflon (tetrafluoroethylene) or Nylon (polyester) or the like
  • Teflon tetrafluoroethylene
  • Nylon polyylon
  • the peripheral end portions of the ring members are turned to extend downwardly substantially perpendicularly to provide a short skirt 36 of cylindrical shape, preferably having openings to enable use ofa pop rivet 38 for securing an annular flange 40, having a central opening 42 dimensioned to correspond to the diameter of the ring member 32, with an upturned portion 44 at the inner periphery which telesopes onto the skirt.
  • the upturned flanged portion 44 is provided with aligned openings for enabling the rivet to extend therethrough to connect the flange 40 onto the ring 32.
  • the flange 40 is split, as at 43, to facilitate mounting onto the ring 32. Instead of riveting the flange onto the ring, the flange can be secured to the ring by other fastening means, with the flange being dimensioned to extend horizontally outwardly for a distance beyond the ring members.
  • the neck tube with the ring members 32 preassembled thereon is joined via the adaptor 46 to the inner vessel, with the opening of the neck tube in communication with the inlet opening 48 through the inner vessel.
  • the inner container is mounted in the insulation fixture and the desired number oflayers ofinsulating material and intermittent layers of heat reflecting barrier strips are applied, as by spiral winding, onto the inner vessel.
  • the insulating operation is stopped and a flange member 40 is secured to the next adjacent ring member, and the heat conducting shield, such as 4 to 20 layers of aluminum foil, are applied, as by winding, onto the insulation to form a layer which overlaps the outer portion of the flanged member 40 short of the ring 32.
  • the application of the insulation layer and occasional reflective barrier sheet is repeated followed by attachment of the next flanged member and application of the heat conductive shield, until the insulation system has been built up in the insulated space.
  • An annular space 50 will exist between the neck tube 18 and the inner edge of the insulation wrapped about the flanged members 40 since the insulation and conductive sheets will be wrapped in a manner which may overlap the flange and a portion of the ring, with such wrapping usually terminating short of the neck tube.
  • the neck tube 18 is provided at its upper end, beyond the insulation, with means for attachment to the outer vessel, but in a manner which enables a limited amount of relative movement while maintaining a sealed relation for evacuation of the space in between.
  • a dome cap 52 having an outlet opening 54 at the top and oftentimes a skirt portion 56 which is received in fitting relation in an opening through the top of the outer vessel 12 and to which it is secured in sealing relation, as by welding 60, whereby the interior of the dome communicates with the insulated space but is sealed from the atmosphere.
  • the neck tube 18 is joined to the dome by way of an expandable bellows 62 secured at its upper end to the dome member by a top neck flange 64 in the form of a sleeve member which is joined at its lower portion to the upper end of the bellows and at its upper portion to the domed member about the outlet opening 54, with a sealing relation between the top neck flange 64 and the dome member.
  • Rod members 66 interconnect the lower end portion of the bellows 62 at the upper end portion of the neck tube 18, whereby the interior of the inner vessel communicates with the outlet in the dome via the aligned openings through the neck tube 18 and bellows 62, with the mounting sleeve members 64 and rods 66.
  • the rod members 66 can be fabricated of poor thermal insulating material, such as titanium, nylon, reinforced plastics, and the like.
  • Means are provided to support the neck tube fro the dome by a suspension which permits angular and turning movements as well as axial movement.
  • the neck tube 18 is supported from the sleeve 64 by way of a plurality of circumferentially spaced apart suspension rods 66 operatively engaged at their upper end portion by a horizontally disposed disc member 68 secured to the neck flange 64 for rigid attachment to the dome and which are pivotally attached at their lower end portion to another disc member 70 secured to the sleeve section 64 rigid with the upper end portion of the bellows 62 which, in turn, receives the upper end of the neck tube in sealing engagement.
  • the rod length is equal to and preferably shorter than the bellows 62.
  • the disc members 68 and 70 are provided with vertically aligned openings 72 through which the rods extend with the through-extending portions having head sections 74 and 76 dimensioned to be greater than the openings 72, and bearing portions 78 and 80 immediately inwardly of the head portions 74 and 76, and which are dimensioned to be slightly less in crosswise dimension than the openings 72 and which are located within the openings in a manner to permit relative axial movements and limited play for relative angular movement.
  • one or both of the through-extending end portions of the suspension rods can be threaded while the head member is in the form of a nut member in threaded engagement therewith to permit axial adjustment of the spaced relationship between the supporting upper and low r discs.
  • the head portion and the adjacent bearing portion at the opposite ends of the bearing rods are connected by a spindle portion 82 of considerably lesser cross section.
  • the disc members 68 and 70 are designed to enable insertion of the rod members into position of use.
  • each of the disc members are formed with a central opening 84 for connection to the top and bottom neck flanges.
  • a number of openings 72, corresponding to the number of suspension rods, are provided in circumferentially spaced apart relation a short distance inwardly from the periphery of the disc member with the openings dimensioned to be less than that of the head portions 74 and 76 but slightly larger than the bearing portions 78 and 80 of the rods.
  • a radial slot 86 extends radially inwardly from the periphery to the opening with the slot dimensioned to have a width slightly greater than the width of the spindle portion 82 but less than the bearing portion to enable the rod to be inserted into the disc by radial displacement of the spindle portion through the slot to the opening and then axial displacement in the opening until the bearing portion is seated within the opening.
  • means are provided to restrict rotation of the inner vessel 12 relative to the outer vessel and dome support.
  • a round disc plate 90 is provided with openings 92 extending therethrough, corresponding in number to the number of suspension rods 66. and on the same circle diameter, so that one opening 92 will be located in axial alignment with each rod.
  • the rods 66 are dimensioned to have a length whereby a machined down end portion 94 extends through the aligned opening 92 in the disc 90, with a clearance therebetween which defines the maximum amount of relative movement between the rod 66 and the disc 90.
  • the outer periphery of the disc member 90 is fixed, as by welding, to the lower end portion of a tubular member 96, which, in turn, is fixed at its upper end portion to the disc member 68 and the sleeve 64 rigid with the dome 52 and the outer container 10.
  • a tubular member 96 which, in turn, is fixed at its upper end portion to the disc member 68 and the sleeve 64 rigid with the dome 52 and the outer container 10.
  • the neck bellows 62 is capable is defined by the clearance between the diameter of the openings 92 and the diameter of the throughextending end portion 94 of the rods 66.
  • block 100 is secured, as by welding, to the tubular member 96 in position to overhang the disc plate 70 in an area between the suspension rods 66.
  • Disc plate 70 being fixed to the neck tube and the block 100 being fixed to the dome and outer container 10, relative vertical movement is restricted to the distance between the top of the disc plate 70 and the bottom of the overhanging block 100.
  • the described construction enables the use of a lesser number of heat conductive shields. This, in turn, enables the use of a shorter neck tube as well as a neck tube of greater wall thickness thereby to provide a structurally strong neck tube assembly which is capable of taking more load and more bend to withstand deflective loads which are many times greater than deflective loads capable of being withstood by prior constructions of the type described.
  • the amount of heat required to be intercepted by the heat shields by conductive conveyance to the neck tube is relatively minor, such that the contact achieved by merely wrapping the heat shield over a portion of the flanged member 40 is sufficient to obtain the desired flux in the insulation system.
  • This minimizes the importance of the neck 'tube as a heat conductive member and therefore enables utilization of a shorter neck tube of greater wall thickness with the advantages as outlined above.
  • a double walled liquefied gas container having an inner storage vessel with an opening at the top for access into the interior of the vessel, an outer shell substantially enclosing said inner shell with an insulation space in between, a neck tube connected at one end to the inner vessel about the opening and at the other end with an opening through the outer shell for the transmission of liquid and vapors therethrough into and out of the vessel, and a composite multi-layered insulation disposed about the inner vessel within said insulated space comprising multi-layers of low thermal insulating material alternating with one or more layers of reflective barrier sheets, the improvement comprising a plurality of rings of high heat conductive material secured in thermally contacting relation along longitudinally spaced apart portions of the neck tube and which extend outwardly from the neck tube for a short distance, disc members formed of thermally conductive material each having a central opening corresponding to the cross section dimension of the rings with one disc member secured at its inner edge portion to each of corresponding ones of said rings in thermally contacting relation, and heat conductive layers extending into the multi-layered
