Abstract
Description
Technical Field
[0001] This utility model relates to the field of cryogenic container technology, and in particular to a vertical cryogenic container. Background Technology
[0002] In the field of cryogenic technology, cryogenic liquids refer to gases that exist in liquid form below -160°C, such as liquid oxygen, liquid nitrogen, liquid argon, liquid hydrogen, liquid helium, and LNG, which are widely used in industrial production, hospitals, and daily life. Containers for storing cryogenic liquids typically consist of a double-layered structure composed of an inner liner and an outer shell, with an insulating interlayer between them. Supporting structures between the inner and outer liner ensure the stability of both structures. Simultaneously, it is essential to minimize the contact area between the inner and outer liner to reduce heat conduction between the inner liner and the external environment, thereby ensuring the overall insulation effect of the container.
[0003] The existing support structure consists of a supporting steel pipe placed between the inner liner and the outer shell, with the supporting steel pipe fixedly connected to the outer surface of the inner liner via a pad. However, for large-volume storage containers, this support structure becomes increasingly ineffective as the weight of the cryogenic liquid inside increases. To stabilize the inner liner, the number of supporting steel pipes needs to be increased; however, increasing the number of supporting steel pipes leads to an increase in the connection area between the inner liner and the outer shell, which in turn affects the thermal insulation performance of the storage container. Utility Model Content
[0004] The purpose of this invention is to provide a vertical cryogenic container with high load-bearing capacity.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vertical cryogenic container, comprising an outer shell and an inner liner disposed within the outer shell, wherein a cylindrical first connector for fixing the inner liner is disposed between the bottom of the outer shell and the bottom of the inner liner, and the first connector has a notch or hole.
[0006] The technical principle of this utility model is as follows: by utilizing the excellent pressure resistance of the cylinder, the inner liner can be supported by the cylinder, and by setting notches or holes, the heat transfer of metal can be greatly reduced, ensuring that the container medium can be stored for a longer time.
[0007] Furthermore, the gaps include a first gap and a second gap that are not interconnected. The first gap is circumferentially and evenly distributed on the side wall of the first connector near the inner liner, and the second gap is circumferentially and evenly distributed on the side wall of the first connector near the outer shell.
[0008] Furthermore, the first gap and the second gap are staggered.
[0009] Furthermore, both the first and second gaps are arc-shaped.
[0010] Furthermore, a first connecting platform for connecting with the inner liner is left between two adjacent first gaps, and a second connecting platform for connecting with the outer shell is left between two adjacent second gaps.
[0011] Furthermore, the surface area of the first connecting platform is smaller than the surface area of the second connecting platform.
[0012] Furthermore, a second connector for fixing the inner liner is provided between the inner liner sidewall and the outer shell inner wall.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The first connector can stably support the inner liner, and the notch on the first connector can greatly reduce metal heat transfer, ensuring that the container medium can be stored for a longer time.
[0015] 2. By setting the first and second notches, the contact area between the first connector and the inner liner is reduced. At the same time, the misaligned first and second notches can increase the area for heat transfer from the outside to the inside of the outer shell, further reducing the heat transfer of the first connector, so that the low-temperature liquid in the inner liner can be stored for a longer time.
[0016] 3. The second connector can restrict the sliding and rotation of the inner liner during transportation. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments; the structures described in various embodiments can be freely combined without conflict in terms of structure or principle.
[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0028] The following description, in conjunction with the accompanying drawings, describes some embodiments of the present invention:
[0029] like Figures 1-4 As shown, this utility model proposes a vertical cryogenic container, including an outer shell 1 and an inner liner 2 disposed inside the outer shell 1. A cylindrical first connector 3 for fixing the inner liner 2 is disposed between the bottom of the outer shell 1 and the bottom of the inner liner 2. The first connector 3 has a notch or hole.
[0030] The material selected for the first connector 3 can be low-temperature resistant steel, S30408 stainless steel, HMA400 high manganese steel, etc. Here, the material selected for the first connector 3 is HMA400 high manganese steel. HMA400 high manganese steel has excellent pressure resistance and can stably support the inner liner 2.
[0031] Furthermore, the presence of notches or holes can significantly reduce heat transfer between metals. To further reduce heat transfer, notches are preferred to ensure that the container medium can be stored for a longer period of time. The lower side of the outer shell 1 is provided with support legs 5 for supporting the container, and the number of support legs 5 is 3. The upper side of the outer shell 1 is provided with lifting lugs 6 for suspending the container, and the number of lifting lugs 6 is 2. Both support legs 5 and lifting lugs 6 are existing technologies and will not be described in detail here.
[0032] Furthermore, such as Figures 2-4 As shown, the gaps include a first gap 301 and a second gap 302 that are not interconnected. The first gap 301 is evenly distributed circumferentially on the side wall of the first connector 3 near the inner liner 2, and the second gap 302 is evenly distributed circumferentially on the side wall of the first connector 3 near the outer shell 1.
[0033] By setting the first notch 301, the contact area between the first connector 3 and the inner liner 2 can be reduced; at the same time, the first notch 301 and the second notch 302 can increase the contact area between the first connector 3 and the inside of the outer shell 1, thereby increasing the area for heat transfer from the outside to the inside of the outer shell 1, and thus reducing the heat transfer of the first connector 3, so that the low-temperature liquid in the inner liner 2 can be stored for a longer time.
[0034] Furthermore, such as Figure 3 and Figure 4 As shown, the first notch 301 and the second notch 302 are staggered, and both the first notch 301 and the second notch 302 are arc-shaped.
[0035] The above settings can further improve the load-bearing capacity of the first support member, enabling the first connector 3 to withstand greater loads.
[0036] Furthermore, such as Figure 3 and Figure 4 As shown, a first connecting platform 303 for connecting to the inner liner 2 is left between two adjacent first notches 301, and a second connecting platform 304 for connecting to the outer shell 1 is left between two adjacent second notches 302.
[0037] As the weight of the cryogenic liquid inside the inner liner 2 gradually increases, the pressure on the connection between the two first notches 301 and the inner liner 2 will gradually increase. When two adjacent first notches 301 are connected, the contact area between the connection between the two first notches 301 and the inner liner 2 is too small, which may cause the first connecting piece 3 to be crushed or the side wall of the inner liner 2 to be damaged. By setting the first connecting platform 303 and the second connecting platform 304, the contact area between the connection between the two first notches 301 and the inner liner 2 can be increased, thereby providing stable support for the inner liner 2.
[0038] Furthermore, such as Figure 3 and Figure 4As shown, the surface area of the first connecting platform 303 is smaller than the surface area of the second connecting platform 304.
[0039] By adopting the above settings, the contact area between the first connector 3 and the inner liner 2 can be reduced, thereby reducing the heat transfer of the first connector 3 and allowing the low-temperature liquid in the inner liner 2 to be stored for a longer period of time.
[0040] Furthermore, such as Figure 2 As shown, a second connector 4 for fixing the inner liner 2 is provided between the side wall of the inner liner 2 and the inner wall of the outer shell 1.
[0041] The second connector 4 is made of fiberglass. The second connector 4 is horizontally positioned between the inner liner 2 and the outer shell 1, which can restrict the sliding and rotation of the inner liner 2 during transportation. Fiberglass has high strength and low heat transfer. The number of second connectors 4 is greater than or equal to 2. To ensure the stability of the inner liner 2, the number of second connectors 4 is preferably 3, and the included angle between two adjacent second connectors 4 is 120°.
