AI Technical Summary
[0003]但现有的液氩储罐保温结构在使用过程中，通常将保温材料填充在液氩储罐的中间层中，然而利用保温绝热材料起到保温的作用，然而此种结构设置的液氩储罐难以有效隔绝热辐射传递，导致液氩储罐保温结构保温效果差的问题，为此我们提出一种液氩储罐保温结构
该种液氩储罐保温结构，通过设置的保温机构，在使用液氩储罐保温结构时，工作人员将液氩内胆位于储罐外壳内，使储罐外壳与液氩内胆之间形成空腔随后将包裹层包裹住金属箔层，并将金属箔层包裹保温填料，随后将保温机构位于空腔中，且在进行保温液氩时，因包裹层采用玻璃纤维加工而成，且包裹层具有导热系数低的作用，形成一层隔热的作用，同时金属箔层具有低辐射的作用，进一步降低辐射热的传递，最后由珠光砂加工而成保温填料起到屏蔽和隔离辐射的作用，将气体热也减弱，并进一步起到隔热作用，因此提高了液氩储罐的保温效果。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid argon storage tank technology, specifically to a liquid argon storage tank insulation structure. Background Technology
[0002] The insulation structure of a liquid argon storage tank refers to a composite structural system with high-efficiency thermal insulation performance designed and constructed on the liquid argon storage tank body to prevent heat from the external environment from entering the tank, reduce vaporization loss of liquid argon due to heat absorption, and maintain a low-temperature storage environment (the boiling point of liquid argon is about -185.85℃).
[0003] However, existing liquid argon storage tank insulation structures typically fill the middle layer of the liquid argon storage tank with insulation material during use, thus relying on the insulation material to achieve the insulation effect. However, this type of liquid argon storage tank structure is difficult to effectively isolate heat radiation transmission, resulting in poor insulation performance. To address this issue, we propose a liquid argon storage tank insulation structure. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a liquid argon storage tank insulation structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a liquid argon storage tank insulation structure, comprising a tank shell, a liquid argon inlet pipe threaded through one side of the tank shell, a vacuum pipe and a vacuum pressure measuring pipe threaded through the other side of the tank shell, a liquid argon outlet pipe threaded through the center of the bottom of the tank shell, a liquid argon inner liner installed inside the tank shell, a cavity formed between the tank shell and the liquid argon inner liner, an insulation mechanism installed inside the cavity, the insulation mechanism comprising insulation filler, a metal foil layer wrapped around the outside of the insulation filler, and a wrapping layer wrapped around the outside of the metal foil layer.
[0006] Preferably, the thermal insulation filler is made of perlite material and has a granular structure.
[0007] Preferably, the metal foil layer is provided in multiple layers, and each metal foil layer has the same thickness.
[0008] Preferably, the wrapping layer is made of glass fiber material and is attached to the outer surface of the liquid argon inner liner and the inner surface of the tank shell.
[0009] Preferably, the bottom of the tank shell is welded with support legs, and three support legs are provided, which are arranged at equal intervals.
[0010] Preferably, the liquid argon liner has a hollow structure and the inner wall of the liquid argon liner is smooth.
[0011] This utility model provides a thermal insulation structure for a liquid argon storage tank, which has the following beneficial effects: This liquid argon storage tank insulation structure, through its designed insulation mechanism, involves placing the inner liquid argon liner inside the outer shell of the storage tank, creating a cavity between the outer shell and the inner liner. A metal foil layer is then wrapped around the outer shell, followed by insulation filler. The insulation mechanism is then positioned within the cavity. During liquid argon insulation, the fiberglass outer layer, with its low thermal conductivity, provides insulation. The low-emissivity of the metal foil further reduces radiant heat transfer. Finally, the perlite-coated insulation filler acts as a shield and isolates radiation, further reducing gas heat and providing insulation. Therefore, the insulation effect of the liquid argon storage tank is improved. Attached Figure Description

[0014] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-4This utility model provides a technical solution: a liquid argon storage tank insulation structure, including a tank shell 1, a liquid argon inlet pipe 2 threaded through one side of the tank shell 1, a vacuum pipe 5 and a vacuum pressure measuring pipe 6 threaded through the other side of the tank shell 1, a liquid argon outlet pipe 4 threaded through the center of the bottom of the tank shell 1, a liquid argon inner liner 9 installed inside the tank shell 1, a cavity 7 opened between the tank shell 1 and the liquid argon inner liner 9, an insulation mechanism 8 installed inside the cavity 7, the insulation mechanism 8 including insulation filler 801, a metal foil layer 802 wrapped around the outside of the insulation filler 801, and a wrapping layer 803 wrapped around the outside of the metal foil layer 802.
[0016] Furthermore, the thermal insulation filler 801 is made of perlite material. The thermal insulation filler 801 has a granular structure and is made of perlite. The thermal insulation filler 801 plays a role in shielding and isolating radiation, reducing gas heat, and further playing a role in heat insulation.
[0017] Furthermore, the metal foil layer 802 is provided with multiple layers, each with the same thickness, which gives the metal foil layer 802 a low radiation effect and further reduces the transfer of radiant heat.
[0018] Furthermore, the wrapping layer 803 is made of glass fiber material. The wrapping layer 803 is attached to the outer surface of the liquid argon inner liner 9 and the inner surface of the tank shell 1, so that the wrapping layer 803 has a low thermal conductivity and forms a heat insulation layer.
[0019] Furthermore, support legs 3 are welded to the bottom of the tank shell 1. There are three support legs 3, which are arranged at equal intervals and can provide support.
[0020] Furthermore, the liquid argon liner 9 has a hollow structure and a smooth inner wall, which allows for better storage of liquid argon.
[0021] Working Principle: After installation, the installation, fixation, and safety protection of this utility model are checked first. When using the liquid argon storage tank insulation structure, the worker places the liquid argon inner liner 9 inside the outer shell 1 of the storage tank, forming a cavity 7 between the outer shell 1 and the liquid argon inner liner 9. Then, the wrapping layer 803 wraps the metal foil layer 802, and the metal foil layer 802 wraps the insulation filler 801. The insulation mechanism 8 is then placed in the cavity 7. When insulating liquid argon, the wrapping layer 803, made of glass fiber, has a low thermal conductivity, forming a heat insulation layer. At the same time, the metal foil layer 802 has low radiation, further reducing the transfer of radiant heat. Finally, the insulation filler 801, made of perlite, acts as a shield and isolates radiation, weakening the gas heat and further providing heat insulation. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
