Description

Technical Field

[0001] This utility model belongs to the field of cryogenic storage tank technology, specifically relating to a heat-insulating interlayer fixing structure for a vertical cryogenic storage tank. Background Technology

[0002] Vertical cryogenic storage tanks are double-layered vacuum-insulated tanks used to store cryogenic media such as liquid oxygen, nitrogen, argon, and carbon dioxide. They are typically vertical in structure. Their core features include a double-layered vacuum insulation design, an austenitic stainless steel inner liner, and outer container materials selected according to regional standards. The interlayer is filled with perlite and vacuumed to achieve efficient insulation. The main function of the insulation interlayer fixing structure in vertical cryogenic storage tanks is to ensure the stability and functionality of the insulation material, preventing displacement or failure caused by external environment or internal pressure.

[0003] In the field of cryogenic storage tanks, especially vertical tanks used for storing cryogenic liquids such as liquid nitrogen and liquid oxygen, the fixation of the insulation jacket is crucial. Traditional methods of fixing insulation jackets have several problems. On the one hand, some fixing structures are complex, and the installation and disassembly processes are cumbersome, increasing construction time and costs. On the other hand, after long-term use, some fixing structures are prone to loosening and deformation due to the effects of the low-temperature environment, leading to displacement of the insulation jacket, affecting the insulation effect, and even potentially damaging the insulation material, reducing the overall performance and service life of the storage tank. In addition, traditional fixing structures do not provide uniform constraint on the insulation jacket, with significant differences in fixing force in different directions, which also affects the stability of the insulation jacket. Therefore, we propose a new insulation jacket fixing structure for vertical cryogenic storage tanks. Utility Model Content

[0006] Preferably, the fixing ring is configured as a first half-ring and a second half-ring, a first connecting member is fixedly installed on one side of the first half-ring, a second connecting member is fixedly installed on one side of the second half-ring, and an adjusting bolt is threadedly rotatably connected between the first connecting member and the second connecting member.

[0007] Preferably, the connecting rod is provided with an outer rod and an inner rod. One end of the outer rod is fixedly connected to the inside of the fixing ring. An installation groove is provided on the inner side of the outer rod. The inner rod is slidably inserted through the inner side of the installation groove. A positioning hole is provided on one side surface of the outer rod. Multiple sets of connecting holes are provided on the surface of the inner rod. A fixing bolt is threadedly rotatably connected between the positioning hole and the connecting hole.

[0008] Preferably, one end of the inner rod is fixedly connected to one side of the elastic plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: A fixing ring is fitted onto the outer wall of the storage tank, and the tightness of the fixing ring is adjusted using adjusting bolts to ensure a tight fit. A connecting rod connects the fixing ring to an elastic clamping plate, which secures the insulation layer. The telescopic design of the connecting rod can be adjusted according to the thickness and position of the insulation layer, ensuring that the elastic clamping plate accurately clamps the insulation layer. The anti-slip texture on the inner side of the elastic clamping plate increases friction with the insulation layer, preventing slippage. Attached Figure Description
