Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature liquid storage, in particular to a sealed tank for low-temperature liquid storage. Background Art

[0002] Cryogenic liquids, such as liquid oxygen, liquid nitrogen, liquid argon, and liquefied natural gas (LNG), evaporate rapidly and turn into gas at room temperature and pressure. This rapid evaporation not only results in the loss of a large amount of material, but may also cause safety hazards due to the rapid accumulation of gas, such as increased pressure or even explosion. Therefore, cryogenic liquids need to be stored in sealed tanks to effectively prevent evaporation and leakage of cryogenic liquids, thereby ensuring the stability and safety of cryogenic liquids.

[0003] Existing sealed tanks are often installed in a fixed installation manner of an inner tank and an outer tank. Although this design ensures the stability and sealing of the structure to a certain extent, it is inconvenient in terms of disassembly, assembly and maintenance.

[0004] For example, a movable low-temperature-resistant liquid storage device is disclosed with announcement number CN214268789U. In this patent, the insulation layer is fixedly arranged inside the outer tank, the pearlescent sand layer is laid inside the insulation layer, and the inner tank is fixedly arranged inside the pearlescent sand layer. Since the inner tank, the pearlescent sand layer and the insulation layer are all fixedly arranged inside the outer tank, once any of the layers is damaged or needs repair, the entire sealed tank needs to be disassembled to a considerable extent before it can be repaired or replaced. This not only increases the difficulty of maintenance, but may also result in a longer maintenance time, affecting the normal use of the sealed tank.

[0005] Therefore, it is necessary to invent a low-temperature liquid storage sealed tank to solve the above problems. Utility Model Content

The multiple No. 1 reinforcing ribs are welded and fixed to the No. 2 reinforcing ribs. The No. 1 and No. 2 reinforcing ribs increase the structural strength of the outer tank body and improve the stability and durability of the overall structure.

[0010] Preferably, the inner wall of the outer tank body is tightly fitted with the outer wall of the insulation layer, and the inner wall of the insulation layer is tightly fitted with the outer wall of the inner tank body. The insulation layer reduces the heat exchange between the cryogenic liquid in the inner tank body and the external environment, maintains the storage temperature of the cryogenic liquid, and improves storage efficiency.
