Definitions

  • This invention pertains to the means for supporting the inner vessel of a multi-walled container such as useable for storing liquefied gases.
  • the invention pertains to inner vessels supported by thin elongated suspension members such as disclosed in US. Pat. Nos. 2,926,810 and 3,163,313.
  • the foregoing patents disclose using thin elongated rods to suspend the inner vessel of a multi-walled container.
  • the rods are used to restrain the'inner vessel and are sized so that expansion or contraction of the inner vessel causing varying loads on the suspension members do not cause the suspension members to fail. This necessitates over designing suspension members since the loads caused by temperature changes are in addition to those required to support the inner vessel.
  • the novel suspension system overcomes the difficulties of the prior art in that thin elongated suspension members are used to support the inner vessel.
  • the support system is arranged so that only tension loads of predetermined levels are placed on any one of the support members. Only one end of the inner vessel, according to the present invention, is completely restrained so that size changes of the inner vessel do not change the load configurations on any of the individual support members.
  • the present invention comprises using thin elongated structural members to support the inner vessel of a multi-walled container.
  • One end of the inner vessel is restrained and the other end of the inner vessel is supported in such a manner as to be free to move relative to the restrained end.
  • the support mechanism is designed so that only tension loading of the elongated support members is achieved.
  • There is also provided removable restraining devices so the container can be shipped via conventional carriers without damage to the inner vessel. The restraining members can be readily removed when the container reaches its destination.
  • FIG. 1 is a sectional view taken along line 1-1 of FIG. 2 showing a multi-walled container according to the present invention.
  • FIG. 2 is a view taken along line 2-2 of FIG. 1.
  • FIG. 1 a multi-walled storage vessel 10 comprising an outer vessel 12 and inner vessel 14 and disposed therebetween a radiation shield 16.
  • the particular embodiment shown in FIG. 1 has reference to a storage vessel for a very low boiling point liquefied gas such as helium.
  • the apparatus of the invention is applicable to other types of multi-walled storage vessels.
  • the outer vessel 12 contains supports 18 and 20 for supporting the container 10 in a horizontal position.
  • Vessel 10 has a pair of dished heads 22, 24 with access ways 26 and 28.
  • the access ways (manway) 26, 28 are provided with closure means 30, 32 for sealing of the outer vessel 12 after onsite installation of the container is complete.
  • closure means 30, 32 for sealing of the outer vessel 12 after onsite installation of the container is complete.
  • Such devices are known in the art.
  • the inner vessel 14 is provided with a pair of dished heads 34 and 36 with support mounting means 38, 40.
  • the support mounting means 38 and 40 are adapted to receive the inner vessel suspension members shown as 42, 44 associated with head 34 (FIG. 2) and 46 being only one of a pair mounted similarly to 42, 44 shown in FIG. 2, for head 36.
  • the suspension members 42, 44, 46 comprise a pair of thin elongated structural elements 48, 50 pivotably connected to outer vessel 12 as shown in reference to support member 42 in FIG. 2.
  • the purpose of the pivotal connection on either end of all support members is to prevent bending stresses on the supports as the inner vessel changes size with temperature changes.
  • the structural members 48, 50 are readily fabricated from plates of stainless steel or other structural materials.
  • the structural members 48, 50 are passed through the radiation shield 16 and pivotably connected to a suitable receiving member 52 on the inner wall of the outer vessel 12.
  • the supports 42, 44, 46 are pivotably connected to the inner vessel at 38 and 40 respectively.
  • suitable insulating members 54, 56, and 58 Associated with the support members 42, 44, 46 are suitable insulating members 54, 56, and 58 tothermally insulate the support members from the radiation shield.
  • Such insulation members can comprise insulating materials such as fiberglass, mats, aluminized mylar, or polyurethane foam.
  • the support members 60, 62 are of a similar construction to members 42, 44, 46 and are used to rigidly fix the end of inner vessel 14 containing head 34. It is shown in the drawings that the left end of the inner vessel 14 is restrained; however, either end can be restrained without departing from the teaching of the present invention.
  • the inner vessel 14 is suspended under pure tension loads on the support members 42, 44, 46, 60 and 62. It will be further appreciated that there is a second support member supporting end 36 of inner vessel 14 and that the support members are fastened so that they can move relative to the fixed end of vessel 14 and placed in identical configuration to those shown in FIG. 2 so that the inner vessel 14 is supported by four members in tension. Members 60 and 62 are then added to restrain one end of inner vessel 14 by applying a tension load to members 60, 62. The inner vessel 14 suspended in this manner allows for movement of said inner vessel 14 due to temperature changes caused by the addition or removal of the cryogenic fluid from the inner vessel.
  • Such size changes in the inner vessel causes the freely movable end (36) of the inner vessel 14 and its associated supports to move relative to the fixed end (34) of vessel 14 because the supports associated with head 36 are pivoted to allow movement thereof. Therefore, it will be appreciated that the size changes do not induce loads on the support members other than those caused by the weight of the inner vessel 14 and the cryogenic fluid addedthereto. Such loads are pure tension loads readily predictable and not subject to change. Therefore, the support system can be designed up to the safe working stress of the structural material and the heat leak due to conduction can be predicted and vthereby minimized by selecting the proper size and composition of the support members.
  • the structural .members are elongated thereby helping to decrease heat losses since the heat loss varies directly with crosssectional area and inversely with length of the support members.
  • Support members 64 and 66 are adapted to restrain movement of the inner vessel 14 during shipment of the container.
  • a suitable connecting device such as a flange with a threaded aperture to receive the bottom threaded end of the support 64 and 66.
  • apertures, such as 68 (FIG. 2) in the radiation shield 16 for passage of the support members therethrough.
  • cover plates 67 and 69 to receive the opposite end of members 64, 66 to be secured to the vessel 12.
  • Supports 64, 66 are made to be engaged in a socket or receiving recess in members 38, 40 respectively and to protrude above cover plates 67, 69 so that cover plates'67, 69 when put in place force rods 64, 66 downwardly and thereby pretension the upper support members 42, 44, 46 and hold the inner vessel securely.
  • Member 63 is removably placed between the inner and outer vessel prior to shipment to prevent rotational and axial movement of the inner vessel 14 and radiation shield 16. Member 63 can be removed at the site by access through manway 26.
  • Restraining of the inner vessel is necessary because the most severe loading is encountered during shipment by rail, truck or other common carrier. Such vibrating and shock loading can cause severe damage to the inner vessel 14 if it is not properly restrained. Members 64, 66 provide the necessary restraint so that the entire container can be shipped without damage to the inner vessel 14. At destination the restraining members 63, 64, and 66 can be readily removed.
  • a container such as disclosed can be used for storing fluids other than the cryogenic fluids.
  • the method of removal of the cryogenic fluid and conversely filling of the container can be of any known type and forms no part of this invention.
  • a stationary double-walled container for storing fluids at other than ambient temperature wherein the double-wall consists of an outer cylindrical vessel and an inner cylindrical vessel held in spaced-apart relation with their principal axes horizontal the improvement which comprises:
  • said means comprising a plurality of elongate tension members said tension members comprising a first pair of tension members one end of each member being secured to the upper inner surface of the outer vessel and the other'end of each member secured to a receiving member on the outer surface of the inner vessel, each of said pair of members being disposed at an angle greater than 0 and less than to a vertical plane containing the principal axis of the container and a second pair of tension members angularly related to each other as said first pair of tension members in a plane generally horizontal rigidly secured at a first end to the inner surface of the outer vessel end wall and at the other end to the outer surface of the corresponding end wall of the inner vessel; means supporting the unrestrained end of the inner vessel, said means including a third pair of elongate tension members in'an angular relationship similar to that of said first pair of tension numbers has been inserted pivotally mounted on the outer vessel to permit the unrestrained end of the
