Description

Technical Field

[0001] This utility model relates to the technical field of thermal insulation devices, and in particular to a high-efficiency thermal insulation device for independent LNG tanks. Background Technology

[0002] LNG stand-alone tanks are independent containers specifically designed for storing liquefied natural gas (LNG). They typically possess characteristics such as resistance to low temperatures, high pressures, and flammability / explosiveness. LNG temperatures are typically around -162°C, therefore special materials capable of withstanding such low temperatures must be selected to ensure its safety and stability.

[0003] The storage performance of LNG stand-alone tanks is mainly reflected in their thermal insulation performance. Because LNG needs to be stored at extremely low temperatures, the tanks need to be made of thermal insulation materials.

[0004] However, existing independent LNG tanks cannot provide efficient thermal insulation during use, which makes LNG prone to high heat transfer and evaporation during storage, affecting the safety and stability of LNG transportation and storage. Utility Model Content

[0005] The main purpose of this utility model is to provide a high-efficiency thermal insulation device for independent LNG tanks, which can effectively solve the problem of not being able to achieve high-efficiency thermal insulation effect.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-efficiency thermal insulation device for an independent LNG tank includes a chassis. Several support seats are fixedly connected in a ring array on the outer side of the upper end of the chassis. A bearing mechanism is fixedly connected to the upper part of the several support seats. A sealing mechanism I is movably connected to the left side of the bearing mechanism. Positioning components are symmetrically fixedly connected to the front and rear sides inside the sealing mechanism I. A thermal insulation mechanism is fixedly connected to the upper part of the bearing mechanism. A sealing mechanism II is movably connected to the upper right side of the thermal insulation mechanism. An inner tank is fixedly connected inside the thermal insulation mechanism. A feed valve body is fixedly connected to the middle of the upper part of the outer surface of the inner tank. A discharge valve body is fixedly connected to the middle of the lower part of the outer surface of the feed valve body.

[0007] Preferably, the heat preservation mechanism includes a heat insulation shell, and the upper right side of the outer surface of the heat insulation shell has a feed port communicating with the outside. A corrugated plate is fixedly connected to the inner cavity of the heat insulation shell.

[0008] Preferably, the second sealing mechanism includes a second limiting plate, the lower end of which is fixedly connected to a second sealing plug, and the second sealing plug is movably connected to the inner cavity of the feed inlet.

[0009] Preferably, the bearing mechanism includes a bearing frame, and a fan-shaped cavity communicating with the outside is provided on the lower left part of the outer surface of the bearing frame. Positioning grooves communicating with the outside are symmetrically provided in the middle of the front wall and the rear wall of the fan-shaped cavity.

[0010] Preferably, the sealing mechanism includes a sector-shaped plate, with a sealing plug fixedly connected to the lower end of the sector-shaped plate, and the outer surface of the sector-shaped plate is slidably connected to the inner cavity of the sector-shaped cavity.

[0011] Preferably, the positioning component includes a fixed sleeve, a spring is fixedly connected to the left wall of the inner cavity of the fixed sleeve, a clamping assembly is fixedly connected to the right side of the outer surface of the spring, and the fixed sleeve is fixedly connected to the sector plate.

[0012] Preferably, the clamping assembly includes a guide post, a positioning hemisphere is fixedly connected to the right end of the outer surface of the guide post, and the left end of the outer surface of the guide post is fixedly connected to the right part of the corresponding outer surface of the spring.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a supporting mechanism to provide stable support for the insulation mechanism and the inner tank. A sealing mechanism prevents the nano-insulation particles inside the insulation mechanism from scattering to the outside. A positioning component locks the sealing mechanism to the left side of the supporting mechanism, improving the device's practicality. The insulation mechanism allows for the loading of nano-insulation materials, and the sealing mechanism seals the opening on the upper right side of the insulation mechanism, enhancing the device's usability and versatility. This invention establishes an annular corrugated plate inside the insulation shell, allowing the nano-insulation particles placed inside the insulation shell to be evenly distributed within the shell. Furthermore, by placing a sufficient amount of nano-insulation particles, the insulation material can fully contact the interior of the insulation shell, thereby ensuring continuous heat preservation of the LNG stored in the inner tank cavity and improving the practicality and versatility of the device.

A fan-shaped cavity 32 communicating with the outside is provided on the lower left side of the outer surface of the supporting frame 31, which can accommodate the fan-shaped plate 41.

A spring 52 is fixedly connected to the left wall of the inner cavity of the fixed sleeve 51, which can guide the extension and retraction of the clamping component 53.

[0023] The working principle of this utility model is as follows: First, the sealing plug 72 is pulled out from the inner cavity of the inlet 62. Then, a sufficient amount of nano-insulation material is added to the inner cavity of the insulation shell 61. At this time, the nano-insulation material added to the inner cavity of the insulation shell 61 will fully fill the inner cavity of the insulation shell 61 along the inner and outer surfaces of the corrugated plate 63, so that the nano-insulation material can fully contact the inner wall of the insulation shell 61. Then, an appropriate amount of LNG is injected into the inner cavity of the inner tank 8 through the feed valve body 9. During this process, the nano-insulation material in the inner cavity of the insulation shell 61 can... To ensure that the LNG gas stored in the inner cavity of the inner tank 8 is fully insulated, when the nano-insulation material in the inner cavity of the insulation sleeve 61 needs to be cleaned and replaced after multiple long-term uses, first pull the fan-shaped plate 41 downward from the inner cavity of the fan-shaped cavity 32. During this process, the two positioning hemispheres 532 will compress the corresponding springs 52 and enter the corresponding inner cavity of the fixed sleeve 51. At this time, an explosion-proof industrial vacuum cleaner can be used with a flexible long-arm suction head to clean the nano-insulation particles in the inner cavity of the feed port 62.
