Description

Technical Field

[0001] The utility model relates to the field of thermal insulation, in particular to a detachable thermal insulation device for a liquefied gas storage tank. Background Technique

[0002] As a clean energy source, the storage and transportation of liquefied natural gas are particularly important. During the storage process of liquefied natural gas, the thermal insulation layer of the storage tank plays a crucial role. It can not only effectively prevent the temperature of liquefied natural gas from rising, but also ensure the safety and efficiency of the storage process. Thermal insulation boards are widely used on various types of storage tanks.

[0003] In the Chinese utility model patent with the publication number CN217482509U, a thermal insulation board for thermal insulation and cold protection of a liquefied gas low-temperature storage tank is disclosed, which includes two prefabricated thermal insulation board bodies. The prefabricated elastic material inside the socket can well absorb the deformation caused by thermal expansion and contraction, thus ensuring the good integrity of the overall structure. And each elastic material is covered with the thermal insulation board body material, maximizing the problem of cold leakage or poor thermal insulation effect at the expansion joint where the elastic material is located.

[0004] In the above structure, the thermal insulation board is integrally formed with sockets and plug boards. When two thermal insulation boards are butted, the sockets and plug boards are inserted and connected. Then, tape is used for connection. After being connected with tape, it is not easy to disassemble again. When one of the thermal insulation boards is broken, it is inconvenient to replace. Moreover, the sizes of different-sized tanks are also different. During installation, some thermal insulation boards need to be cut accordingly due to their sizes and the obstruction of surrounding objects, which may cause the plug boards and sockets to be cut off and unable to be effectively connected. For this reason, we have designed a detachable thermal insulation device for a liquefied gas storage tank. Summary of the Utility Model

[0005] To solve the technical problem that the thermal insulation board is not easy to disassemble, resulting in inconvenience in subsequent replacement, the utility model provides a detachable thermal insulation device for a liquefied gas storage tank.

[0006] The utility model is realized by the following technical solutions: A detachable thermal insulation device for a liquefied gas storage tank includes a thermal insulation board. A first connection groove is penetrated through the middle of the left and right sides of the thermal insulation board, and a second connection groove is penetrated through the middle of the upper and lower sides of the thermal insulation board. Connection bars are inserted into both the first connection groove and the second connection groove, and two adjacent thermal insulation boards are connected by the connection bars.

[0007] As a further improvement of the above solution, a first elastic material is tightly pressed at the connection of two adjacent thermal insulation boards. The provided first elastic material can abut against the adjacent thermal insulation board, maximizing the problem of cold leakage or poor thermal insulation effect caused by gaps due to thermal expansion and contraction at the connection.

[0008] As a further improvement of the above solution, the insulating board includes an inner plate, and a first heat preservation board is respectively arranged at four corners of the inner plate. An outer plate is installed above the four first heat preservation boards by screws. When the insulating board is produced, multiple components are prefabricated and connected into one body. It can disassemble the outer plate according to needs. Then, when there is an obstruction on the side, the insulating board can be directly clamped beside an adjacent insulating board, and the connecting strip can be inserted into the first connecting groove and the second connecting groove.

[0009] As a further improvement of the above solution, there are spaces between the four first heat preservation boards to form a first connecting groove and a second connecting groove, and the first connecting groove and the second connecting groove are in a cross-shaped structure. The connecting strip can be inserted into the first connecting groove and the second connecting groove, so as to quickly connect and splice two adjacent insulating boards;

[0010] A second heat preservation board is arranged at the overlapping part of the first connecting groove and the second connecting groove. The second heat preservation board is made of the same material as the first heat preservation board and is used to abut against the connecting strip, so that there are no gaps inside the insulating board, improving the heat preservation and heat insulation effect.

[0011] As a further improvement of the above solution, the length of the connecting strip is twice the length of the first heat preservation board, and elastic material II is adhesively bonded to the left and right surfaces of the connecting strip. The connecting strip can be inserted into the first connecting groove and the second connecting groove and can abut against the second heat preservation board, and the provided elastic material II can abut against the first heat preservation board on the side, maximizing the prevention of problems such as cold leakage or poor heat preservation caused by gaps due to thermal expansion and contraction at the connection.

[0012] As a further improvement of the above solution, the insulating board is in an overall square structure, and the structures and sizes of the first connecting groove and the second connecting groove are the same. The upper, lower, left, and right sides of the insulating board can all be cut accordingly, reducing the size of the entire insulating board, and thus facilitating its installation in a smaller space when needed finally.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, a first connecting groove and a second connecting groove are respectively arranged on the upper, lower, left, and right sides of the insulating board. With the cooperation of the provided connecting strip, multiple insulating boards can be directly inserted, thus facilitating their quick splicing. Moreover, the outer plate on the front side of the insulating board can be removed, facilitating the pushing of the insulating board in the corresponding space and the installation of the insulating board. When disassembling, only the outer plate needs to be removed to remove the corresponding insulating board, which also facilitates subsequent disassembly and replacement;

[0015] 2. By arranging the first elastic material between two adjacent heat insulation plates and arranging the second elastic material between the connecting strip and the first and second connecting grooves, they can be in contact with the heat insulation plates, thus maximizing the prevention of problems such as cold leakage or poor heat preservation caused by gaps due to thermal expansion and contraction at the joints.

[0023] Next, with reference to the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0024] Embodiment:

[0025] Please refer to Figures 1-5 , a detachable heat insulation device for a liquefied gas storage tank in this embodiment includes a heat insulation plate 1. The first connecting grooves 2 are penetrated through the middle positions on the left and right sides of the heat insulation plate 1, and the second connecting grooves 6 are penetrated through the middle positions on the upper and lower sides of the heat insulation plate 1. Connecting strips 3 are inserted into both the first connecting grooves 2 and the second connecting grooves 6, and two adjacent heat insulation plates 1 are connected by the connecting strips 3.

[0026] The first elastic material 4 is tightly pressed at the joint of two adjacent heat insulation plates 1. The arranged first elastic material 4 can be in contact with the side heat insulation plates 1, thus maximizing the prevention of problems such as cold leakage or poor heat preservation caused by gaps due to thermal expansion and contraction at the joints.

[0027] The heat insulation board 1 includes an inner board 11. At each of the four corners of the inner board 11, a first heat insulation board 12 is provided. Above the four first heat insulation boards 12, an outer board 13 is installed by screws. When the heat insulation board 1 is produced, multiple components are prefabricated and connected as a whole. It can detach the outer board 13 as needed. Thus, when there is a shield on the side, the heat insulation board 1 can be directly clamped beside an adjacent heat insulation board 1, and the connecting strip 3 can be inserted into the first connecting groove 2 and the second connecting groove 6.

[0028] There are spaces between the four first heat insulation boards 12 to form the first connecting groove 2 and the second connecting groove 6. The first connecting groove 2 and the second connecting groove 6 are in a cross-shaped structure. The connecting strip 3 can be inserted into the first connecting groove 2 and the second connecting groove 6, so as to quickly connect and splice two adjacent heat insulation boards 1.

[0029] A second heat insulation board 14 is arranged at the overlapping part of the first connecting groove 2 and the second connecting groove 6. The second heat insulation board 14 is made of the same material as the first heat insulation board 12 and is used to abut against the connecting strip 3, so that there are no gaps inside the heat insulation board 1, improving the heat insulation effect.

[0030] The length of the connecting strip 3 is twice the length of the first heat insulation board 12. Elastic materials II 5 are adhesively bonded to the left and right surfaces of the connecting strip 3. The connecting strip 3 can be inserted into the first connecting groove 2 and the second connecting groove 6 and can abut against the second heat insulation board 14. The provided elastic materials II 5 can abut against the first heat insulation boards 12 on the side, maximizing the prevention of problems such as cold leakage or poor heat insulation caused by gaps due to thermal expansion and contraction at the joints.

[0031] The heat insulation board 1 is in an overall square structure. The structures and sizes of the first connecting groove 2 and the second connecting groove 6 are the same. The upper, lower, left, and right sides of the heat insulation board 1 can all be cut accordingly, reducing the size of the entire heat insulation board 1, and thus facilitating its installation in a smaller space when needed finally.

[0032] The implementation principle of a detachable heat insulation device for a liquefied gas storage tank in the embodiment of the present application is as follows: In actual use, one heat insulation board 1 is fixed on the surface of the liquefied gas storage tank by screws or other means. Then, a connecting strip 3 can be inserted on its side and the connecting strip 3 is made to contact the second heat insulation board 14. Then, another heat insulation board 1 can be inserted on the connecting strip 3 through the first connecting groove 2 and the second connecting groove 6. Elastic material I 4 (elastic material I 4 and elastic material II 5 include melamine foam, sponge, high elastic polyurethane foam, polyethylene, elastic felt, glass wool or PEF) is filled at the joint of the two adjacent heat insulation boards 1, and the two heat insulation boards 1 are squeezed against each other.

[0033] In the above manner, multiple heat insulation boards 1 can be sequentially spliced on the surface of the liquefied gas storage tank. Just select some of the heat insulation boards 1 and connect and fix them to the liquefied gas storage tank. When there are obstacles on the side that prevent the heat insulation board 1 from being inserted, remove the outer plate 13 on the part of the heat insulation board 1 in this area, push another heat insulation board 1 from front to back into the space of the heat insulation board 1 that has been fixed, press the connecting strip 3 in for fixation, and finally fix the outer plate 13 on the front side of the heat preservation board 12;

[0034] When disassembling, remove the outer plate 13 on the front side of the corresponding heat insulation board 1, and the corresponding heat insulation board 1 can be removed as a whole;

[0035] By providing a first connecting groove 2 and a second connecting groove 6 on the upper, lower, left and right sides of the heat insulation board 1 respectively, and cooperating with the provided connecting strip 3, multiple heat insulation boards 1 can be directly inserted, which is convenient for their quick splicing. Moreover, the outer plate 13 on the front side of the heat insulation board 1 can be removed, which is convenient for pushing the heat insulation board 1 into the corresponding space, facilitating the installation of the heat insulation board 1. And when disassembling, just remove the outer plate 13 to remove the corresponding heat insulation board 1, which is also convenient for subsequent disassembly and replacement;

[0036] By providing a first elastic material 4 between two adjacent heat insulation boards 1, and providing a second elastic material 5 between the connecting strip 3 and the first connecting groove 2 and the second connecting groove 6, they can be in contact with the heat insulation board 1, maximizing the prevention of problems such as cold leakage or poor heat preservation caused by gaps due to thermal expansion and contraction at the joints.
