Detailed Description
The following embodiments are merely examples.
The present invention provides a thin film metal plate and a liquefied gas containing tank having the same, which is a containing tank for transportation equipment, particularly marine equipment such as ships, for example, a containing tank for storing concentrated natural gas for ships. The containment tank may also be a land-based device. Fig. 1 to 6 show schematic views of a thin film metal plate according to a preferred embodiment of the present invention.
It is first noted that the terms of the present invention should be construed as relative descriptions rather than absolute descriptions. For example, the terms "top side", "upward", "bottom side", "downward", etc. of the various components of the processing apparatus may be explained with reference to the placement orientation of the thin film metal sheets shown in fig. 1-5; the "first horizontal direction" and the "second horizontal direction" are two directions perpendicular to each other, wherein the first horizontal direction is indicated by D2, the second horizontal direction is indicated by D1, and the first horizontal direction D2 and the second horizontal direction D1 together define an extension plane of the thin film metal plate body 10 of the thin film metal plate. The height direction D3 is a direction perpendicular to the thin film metal plate body 10.
Referring first to fig. 1, a thin film metal plate 100 includes a thin film metal plate body 10 in the form of a flat plate, first and second horizontal corrugations 30 and 20 formed on the thin film metal plate body 10, and a protruding bulge region 40 where the second and first horizontal corrugations 20 and 30 meet. The second horizontal corrugations 20 of the thin film metal plate 100 refer to corrugations extending in the second horizontal direction D1, and the first horizontal corrugations 30 refer to corrugations extending in the first horizontal direction D2. In the embodiment shown in fig. 1, the dimension in the second horizontal direction of the first horizontal corrugation 30 tapers in the direction from the bottom side to the top side, and the dimension in the first horizontal direction of the second horizontal corrugation 20 tapers in the direction from the bottom side to the top side. And, the height of the second horizontal corrugation 20 is smaller than the height of the first horizontal corrugation 30, and the largest first horizontal dimension of the second horizontal corrugation 20 is smaller than the largest second horizontal dimension of the first horizontal corrugation 30. In other words, the transverse corrugations are large corrugations and the longitudinal corrugations are small corrugations. The heights of the second horizontal corrugation 20 and the first horizontal corrugation 30 refer to the distance between the topmost end of the corrugation and the thin film metal plate body 10 in the height direction D3.
In the present embodiment, the first horizontal corrugation 30 and the second horizontal corrugation 20 are circular arc corrugations, for example, in the projection plane shown in fig. 2 and the projection plane shown in fig. 3, the projection profiles of the first horizontal corrugation 30 and the second horizontal corrugation 20 are circular arcs, the tips of the respective circular arcs are circular arcs without edges, and the sides of the circular arcs are walls with radians. In other embodiments, not shown, the first horizontal corrugation and/or the second horizontal corrugation may be formed as triangular corrugations, for example in their respective cross-sections (which are perpendicular to the direction of extension of the corrugation), the cross-sectional profile of which is formed as a substantially triangle.
In this embodiment, the bulge area 40 is formed in a dome shape along the first horizontal corrugation as a whole, and spans the second horizontal corrugation, and has a height larger than that of the first horizontal corrugation 30. The bulge area 40 covers the top side of the first horizontal corrugation 30 in a shape-fitting manner with the first horizontal corrugation 30, which means that the bulge area 40 is substantially formed in a shape conforming to the dome shape of the first horizontal corrugation 30, that is, the cross-sectional profile of the bulge area 40 is also formed in a dome shape in a cross-section taken by the first horizontal direction D2 and the height direction D3. Further, the bulge area 40 extends substantially also in the second horizontal direction D1 and has an extension length which is larger than the largest first horizontal dimension of the second horizontal corrugation 20. Preferably, referring to fig. 2, the extension length D1 of the bulge area 40 in the second horizontal direction D1 is two to four times, preferably three times, the dimension D2 of the second horizontal corrugation 20 in the largest second horizontal direction.
In the present embodiment, referring to fig. 1, 2 and 4, the end surface 41 of the bulge area 40 in the second horizontal direction D1 is a straight wall surface perpendicular to the thin film metal plate body 10. It can be seen that the bulge region 40 has a sharp deformation at the end in the second horizontal direction D1, and such an arrangement can promote the telescoping force, elasticity and tension at the bulge region 40.
Preferably, the radius of curvature of the dome shape constituted by the bulge area 40 is different from the radius of curvature of the dome shape constituted by the transverse corrugations, so that the distance between the bulge area 40 and the corresponding area of the first horizontal corrugation 30 is not uniform in the direction along the dome shape constituted by the bulge area 40. For example, referring to fig. 3, at a top position of the bulge region 40, a spacing between an outer surface of the bulge region 40 and an outer surface of the first horizontal corrugation 30 is maximized; the outer surface of the bulge area converges downward from the top position and toward the end surface thereof in the first horizontal direction, and at the bottom position of the bulge area 40 (i.e., at the position intersecting the thin film metal plate body 10), the outer surface of the bulge area 40 almost abuts against the first horizontal corrugation 30, where the contour line of the bulge area 40 and the contour line of the first horizontal corrugation 30 almost coincide as can be seen from fig. 3. Preferably, the height of the first horizontal corrugation 30 is three to four times the distance between the tip of the bulge area 40 and the tip of the first horizontal corrugation 30.
In the present embodiment, the bulge area 40 has expansion sections 42 at positions on both sides of the second horizontal corrugation 20, and the expansion sections 42 gradually increase in size in the second horizontal direction in a direction from the top to the bottom of the bulge area 40. That is, referring to fig. 3, the profile of the expansion section 42 generally forms a tapered structure with a minimum dimension in the second horizontal direction at the top and a maximum dimension in the second horizontal direction at the bottom.
Further, the bulge region 40 further has a middle section 44 at the top side of the second horizontal corrugation 20 and end sections 43 at both ends of the bulge region 40, wherein, referring to fig. 6, a dimension d5 of the end sections 43 in the largest second horizontal direction is smaller than a dimension d4 of the expansion section 42 in the largest second horizontal direction, and a dimension d3 of the middle section 44 in the largest second horizontal direction is smaller than a dimension d5 of the end sections 43 in the largest second horizontal direction.
Turning back to fig. 1, the side wall 45 of the intermediate section 44 of the sheet metal is close to perpendicular to the plane of the sheet metal body 10. The side walls of the intermediate section 44 are steeper and the shape deformation is steeper than the side walls of the expansion section 42.
Referring to fig. 2, in a projection plane defined by the second horizontal direction D1 and the height direction D3, the top projection profile 46 of the bulge area 40 is a straight line segment extending along the second horizontal direction D1. Referring to fig. 5, in a cross section defined by a first horizontal direction D2, a height direction D3, and passing through the center of the thin film metal plate, the cross-sectional profile of the bulge area 40 includes a top profile 442 and a side profile 441 connected between the top profile 442 and the second horizontal corrugation 20, the side profile 441 being a straight line segment having an angle α with the height direction D3, 5 ° - α -15 °.
The bulge area of the film metal plate has uniform deformation amount, so that the bulge area can provide relatively uniform elasticity and tension. In addition, the bulge area is easy to form and is convenient for the production and manufacture of the thin film metal plate.
The thin film metal plate shown in fig. 1 to 6 may be used as a sealing layer of a receiving can, the structure of which is shown in fig. 7 to 9. The directional terms, positional terms referred to in connection with the canister of the present invention may be understood with reference to the positions, directions, etc. of the respective components shown in fig. 7 to 9. For example, in the present invention, "inside", "inwardly" may be understood as the side of the wall of the holding tank holding liquefied gas and the direction towards the side holding liquefied gas; "outside", "outward" are the sides of the walls facing the outside and the direction toward the outside; "circumferential direction" and "radial direction" refer to the circumferential direction and the radial direction for a circle circumscribed by a circular or nearly circular regular polygon (including a shape similar to a regular polygon) formed by the bottom wall and the bottom wall seal layer. It should be noted that the directional terms used when describing the thin film metal plate alone and the directional terms describing the accommodating tank when the thin film metal plate is mounted in the accommodating tank are not necessarily identical.
Referring first to fig. 7 and 8, the wall of the receiving can includes a base layer 400 and a sealing layer covering the inside of the base layer 400, the sealing layer being made of the thin film metal plate according to the above-described embodiment.
The wall has a central section and an annular section. Specifically, the seal layer includes a central section 310 and at least one annular section 320 disposed around the central section 310, each annular section 320 including a plurality of annular section seal plates 3210, the plurality of annular section seal plates 3210 being cut from a sheet of thin film metal. Each annular segment has a gap 350 between adjacent cells, and a first sealing connection may be provided in the gap 350, for example, between circumferentially adjacent seal plates 3220 and securing both to the base layer 400. The central section 310 is formed by a fan-shaped central sealing plate 3110. The base layer also has a base layer center section 420 and a base layer annular section 410, the base layer annular section 410 being made up of base layer cell plates 4110.
Further, the annular sections 320 are at least two, the at least two annular sections 320 are circumferentially arranged in sequence, and the sealing layer further includes a second sealing connector 340, the second sealing connector 340 being disposed between adjacent annular sections 320 and securing the adjacent annular sections to the base layer 400. Three annular sections are shown-a first annular section 420a, a second annular section 420b and a third annular section 420c. In other embodiments not shown, there may be fewer or more annular sections.
The first horizontal corrugation and the second horizontal corrugation of each ring segment sealing plate 3210 of the ring segments form radial corrugation and circumferential corrugation of the ring segments 320, respectively, wherein a part of the radial corrugation 380 extends from the radial inner end to the center segment 310, and the other part of the radial corrugation 360 is located at the middle of the ring segments 320 and away from the center segment 310, which arrangement can avoid that the circumferential length (S1 and S2 shown in the figure) between adjacent radial corrugations is too large at the radial outer position of the ring segments, resulting in poor stability and ductility, and a radial corrugation is additionally arranged between such adjacent radial corrugations, so that the maximum circumferential distance between the adjacent radial corrugations in the circumferential direction can be within a predetermined range. For example, if the distance between the radially inner ends of an adjacent pair of radial corrugations 380 is X, the maximum circumferential distance between circumferentially adjacent radial corrugations in the annular section may be between 1.5X-5X. Preferably, a sealing end cap 370 is mounted at the radially inner end of each of said radial corrugations.
Fig. 9 shows a rectangular wall. The sealing layer includes sealing layer film metal plates 520 arranged in an array, wherein adjacent sealing layer film metal plates along a first horizontal direction are connected and sealed by a first sealing connector 5210, and adjacent sealing layer film metal plates along a second horizontal direction are connected and sealed by a second sealing connector 5220. The base layer 510 also includes base layer plates arranged in an array, gaps 5110 are provided between adjacent base layer plates, and the thin film metal plates have corrugations extending in the same direction as each gap, and the corrugations cover the gaps.
As can be seen from the above embodiments, the sealing layer of the accommodating tank of the present invention can be made of standard components with regular shapes, no section with special shape is needed, and the standard components can be obtained by simply cutting a rectangular plate, so that the processing is simple and the materials are saved; the sealing layer has good flatness, has small damage degree to the heat insulation layer structure, and can reduce the influence of the sealing layer on the strength of the heat insulation box; the sealing layer structure determines that the sealing layer can be made thinner, so that the overall heat conduction coefficient of the heat storage container can be reduced, and the heat preservation effect is improved. Furthermore, sealing connecting pieces serving as universal pieces can be adopted between adjacent standard pieces, and certain sealing connecting pieces have certain heat elasticity and can provide certain cold shrinkage deformation for sealing layers. In addition, the sealing connecting piece does not need to carry out additional processing operations such as edging and the like on the sealing layer unit plates, so that the flatness of the sealing layer can be improved, and the sealing effect is ensured. The bottom wall sealing layer has no convex part, and two layers of sealing layers and heat insulation layers are paved, so that the back surface of the heat insulation layer on the upper layer does not need to be grooved, and the structural strength of the heat insulation layer is improved. The holding tank of the invention is a marine equipped liquefied gas holding tank or a land cryogenic liquid plant.
Modifications, rearrangements and adaptations of the embodiments described herein will occur to those skilled in the art without departing from the scope of the invention.
