Embodiment
The exemplary embodiments embodying the utility model feature & benefits will describe in detail in the following description.Be understood that the utility model can have various changes in different embodiments, it neither departs from scope of the present utility model, and explanation wherein and to be shown in be use when explain in essence, and be not used to limit the utility model.
The utility model embodiment provides a kind of supporting structure of low-temperature pressure container, and this low-temperature pressure container has outer container 7 and an inner container 6, and low-temperature pressure container cross section is generally cylindrical shape, and outer container 7 is positioned at outside inner container 6, and there is certain gap centre; Multiple supporting structure is installed between outer container and inner container, and for supporting the gap between outer container 7 and inner container 6, supporting structure comprises: location closure plate 1, sandwich plate 2, thermal-protective coating 3, heat insulation support pipe 4, support ring 5.
As shown in Figure 2, in this embodiment, location closure plate 1 is installed on outer container 7, location closure plate can be cylindrical, it is stepped hollow structure inside it, the periphery of inner side can be a ring-shaped step 11, and ring-shaped step 11 is formed at least one annular heat groove 12, and it is mainly in order to extend heat transfer length; The middle part of location closure plate 1 is locating slot 13, locating slot bottom surface is formed a location indentations 14.
As shown in Figure 2, in this embodiment, sandwich plate 2 is layed in the locating slot 13 of location closure plate 1, as shown in (a) in Fig. 4, sandwich plate 2 forms a positioning convex portion 21 towards the Middle face of locating closure plate 1 and (certainly also can be recessed structure, a protuberance is established to carry out engaging as long as locating slot 13 bottom surface also coordinates), the engaging that positioning convex portion 21 and location closure plate 1 location indentations 14 of sandwich plate 2 can be male-female engagement is located.And be provided with a thermal-protective coating 3 between sandwich plate 2 and location closure plate 1, material can be the cryogenic insulating paper of glass fibre and/or aluminium foil compound, and its main purpose is utilize the slower principle of heat transfer rate between unlike material to reduce cold draining amount.Here the height of positioning convex portion 21 is greater than the degree of depth of location indentations 14, so can ensure to have certain intervals between sandwich plate 2 and location closure plate 1, thus keep insulation effect, thermal-protective coating 3 also can be allowed to play a role better simultaneously.
Sandwich plate 2 generally selects stainless steel, certainly, also can be identical with location closure plate 1, all select carbon steel forging.
As shown in Figure 2, in this embodiment, it is cylindrical that heat insulation support pipe 4 corresponds to location closure plate 1, and positioning end 41 and the sandwich plate 2 of heat insulation support pipe 4 abut against, and is locked in the locating slot 13 of location closure plate 1; The support end 42 of heat insulation support pipe 4 is positioned support ring 5 in the mode of inner hole sleeve group, support ring 5 be fixedly installed on the outer surface of inner container by modes such as welding, support ring 5 changes into being fixed on inside heat insulation support pipe 4 can increase heat conduction length.When support end 42 is with during with sliding end, support ring 5 can be removed, the object reducing heat transfer can be played equally.
Heat insulation support pipe generally selects epoxy glass laminate, certainly, also can select the composite material that other intensity is high, heat-transfer coefficient is little.
As shown in Figure 3, in the utility model one preferred embodiment, the outer shape supporting closure plate 1 also can be cylindrical or bores post in conjunction with shape, and as shown in Fig. 3 (c), cone post is say that side has the shape of one section of conical surface and one section of cylndrical surface in conjunction with shape.Can strengthen like this and support the structural strength of closure plate 1, thus reduce the impact of offering on intensity after annular heat groove 12.
As shown in (b), (c) in Fig. 4, in the utility model preferred embodiment, the upper surface 22 of sandwich plate 2, that is offer at least one groove 221 or through hole 222 corresponding on the face of heat insulation support pipe 4, can certainly two kinds of mode Combination application, mainly in order to reduce the area of contact of heat insulation support pipe 4 and sandwich plate 2, thus reach the object reducing cold draining.
As shown in (d), (e) in Fig. 4, in another preferred embodiment of the utility model, in the positioning convex portion 21 of sandwich plate 2, that is correspond to support closure plate 1 face on offer at least one groove 211 and/or through hole 212, it mainly in order to reduce sandwich plate 2 and the area of contact supporting closure plate 1, thus reaches the object reducing cold draining.
Several structures of the sandwich plate 2 shown in Fig. 4, though illustrate respectively for middle part and outer peripheral portion, those skilled in the art can be clear, also two-part can be carried out Combination application, realizes the object reducing cold draining simultaneously.
As shown in Figure 5, in the utility model one preferred embodiment, the outside of outer container 7 cylindrical shell of this low-temperature pressure container is also provided with at least one stiffening ring 8, multiple stiffening ring 8 can upwards be arranged at interval by vessel axis outside, stiffening ring can be made up of channel-section steel, be welded in outside outer container, outer container stiffening ring is segment design, centre is provided with interruption part, interruption part says, when horizontal width is certain, stiffening ring symmetry two outside can be provided with parallel otch, two otch are all positioned at symmetrical outside, as shown in Figure 5, be provided with the otch being parallel to vertical line in the horizontal direction, so that be positioned in former vehicle space.Owing to changing into external by the stiffening ring of prior art, outer container volume can be increased, thus inner container volume can be increased.Shell is calculated by stress analysis and meets stability of external pressure requirement.
In sum, the utility model, by increasing sandwich plate between heat insulation support pipe and location closure plate, effectively solves when inner container volume increases, and the problem that when the interlayer gap between outer container reduces, heat-insulating property is not good; And by the stiffening ring of outside of containers increase outside, improve the stability of shell.
Although exemplary embodiment describe the utility model with reference to several, should be appreciated that term used illustrates and exemplary and nonrestrictive term.Specifically can implement in a variety of forms due to the utility model and not depart from spirit or the essence of model utility, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in claim of enclosing, therefore fall into whole change in claim or its equivalent scope and remodeling and all should be claim of enclosing and contained.
