Description

Technical Field

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

[0002] At present, cryogenic storage tanks all adopt a double-layer cylindrical structure, including an inner container and an outer container. The inner container, as the most important component of the cryogenic storage tank, stores mostly flammable, explosive and harmful liquefied gases and cryogenic liquids (such as liquid oxygen, liquid nitrogen, liquid argon, liquid natural gas, liquid carbon dioxide, liquid ethylene, etc.).

[0003] Since the outer container of the above-mentioned storage tank is generally large in size and the thickness of the outer container shell is relatively thin, most of the time during production, an annular reinforcement plate is set on the inner side of the outer container shell to strengthen the strength of the outer container. Although this strengthens the strength of the outer container shell, the interlayer between the outer container and the inner container needs to be filled with pearlescent sand to support the inner container. Since the angle between the two sides of the annular reinforcement plate and the shell is very small, generally 90 degrees, dead corners and gaps are prone to occur. During the transportation and use of the storage tank, the pearlescent sand will flow in the tank body, causing the inner container to sink, or the storage tank will sweat or even frost during use, affecting the service life of the storage tank.

[0004] In view of this, a reinforced low-temperature storage tank is urgently needed. Summary of the invention

[0005] In view of the problems existing in the prior art, the utility model solves the problems with the following technical structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A reinforced cryogenic storage tank, comprising: an outer shell and an inner shell, wherein the inner shell is arranged in an inner cavity of the outer shell, an interlayer is arranged between the outer shell and the inner shell, the interlayer is filled with thermal insulation sand, and a plurality of reinforcement members are arranged on the inner side wall of the outer shell from top to bottom;

[0008] The reinforcement member includes two annular support plates whose outer sides are connected to the inner side wall of the outer shell. The two annular support plates are connected to each other at one side close to the inner shell and form an angle with the opening facing the outer shell.

[0009] A further feature is that

[0010] The angle is not less than 90 degrees.

[0011] The angle is degrees.

[0012] The reinforcement member also includes a reinforcement plate arranged between the two annular support plates, one side of the reinforcement plate is connected to the inner side wall of the outer shell, and the other side is connected to the connection point of the two annular support plates.

[0013] A plurality of the reinforcement members are arranged in parallel.

[0014] The thermal insulation sand is pearl sand or perlite particles.

[0015] A plurality of support frames are arranged at the bottom of the outer shell.

[0016] The reinforcement member is made of steel.

[0017] At least six reinforcement members are provided.

[0018] A filling port is arranged on the top of the outer shell.

[0019] The above structure of the utility model can achieve the following beneficial effects:

[0020] By forming an obtuse angle (preferably greater than 120 degrees) between the two annular support plates and the outer shells on both sides, the fluidity of the insulating sand is greatly increased when filling it, and the insulating sand can more easily pass over the reinforcements formed by the annular support plates, which can effectively avoid the probability of dead corners on both sides of the reinforcements, making the insulating sand in the interlayer filled more compactly, reducing the sinking of the insulating sand during use or transportation, thereby effectively reducing the sweating of the storage tank, and even frosting and increasing the evaporation rate.

[0025] The following is combined with Figure 1 This application is described in further detail.

[0026] refer to Figure 1 A reinforced cryogenic storage tank shown in the figure comprises: an outer shell 1 and an inner shell 2, the inner shell 2 is arranged in the inner cavity of the outer shell 1, an interlayer is arranged between the outer shell 1 and the inner shell 2, the interlayer is filled with thermal insulation sand, and a plurality of reinforcements are arranged on the inner wall of the outer shell 1 from top to bottom; the reinforcement comprises two annular support plates 3 connected to the inner wall of the outer shell 1 on the outside, the two annular support plates 3 are connected to each other on one side close to the inner shell 2, and form an angle with the opening facing the outer shell 1, so that the inner sides of the two annular support plates 3 are connected, and an angle (shape and angle) facing the outer shell 1 is formed. Steel is similar), so that an obtuse angle greater than 90 is formed between the two annular support plates 3 and the outer shells on both sides (the annular support plate 3 on the upper side and the inner wall of the outer shell 1 on the upper side, and the annular support plate 3 on the lower side and the inner wall of the outer shell 1 on the lower side). When filling the insulating sand, the insulating sand can more easily pass over the reinforcement formed by the annular support plates 3, thus reducing the probability of dead angles, making the insulating sand in the interlayer filled more compactly, reducing the movement of the inner shell 2 relative to the outer shell 1 during use or transportation, and reducing the sweating and even frosting of the storage tank.

[0027] Further optimization is that the angle is not less than 90 degrees, and the optimal angle is 90 degrees. During production, reasonable adjustments are made according to demand.

[0028] refer to Figure 1 As shown, in order to further improve the strength of the outer shell 1, the reinforcement also includes a reinforcement plate 4 arranged between the two annular support plates 3, one side of the reinforcement plate 4 is connected to the inner wall of the outer shell 1, and the other side is connected to the connection between the two annular support plates 3. In this way, the reinforcement plate 4 is added between the two annular support plates 3, and an additional fulcrum is provided to the outer shell 1, thereby increasing the strength of the outer shell 1.

[0029] Further optimization is that the thermal insulation sand is preferably pearl sand or perlite particles.

[0030] A further optimization is that in order to make the strength of each part of the outer shell 1 more balanced and reasonable, multiple reinforcements are arranged in parallel. At the same time, in order to ensure that the strength of the outer shell 1 is greatly improved, at least six reinforcements are arranged.

[0031] refer to Figure 1 As shown, in order to facilitate the placement and use of the storage tank, a plurality of support frames 5 are provided at the bottom of the outer shell 1 to support the storage tank and ensure the stability of the storage tank.

[0032] It is further optimized that in order to ensure the strength and durability of the reinforcement member, the reinforcement member is preferably made of steel.

[0034] In summary, by forming an obtuse angle (preferably greater than 120 degrees) between the two annular support plates and the outer shells on both sides, the fluidity of the insulating sand is greatly increased when filling the insulating sand, and the insulating sand can more easily pass over the reinforcement formed by the annular support plate 3, which can effectively avoid the probability of dead angles on both sides of the reinforcement, so that the insulating sand in the interlayer is filled more compactly, and the sinking of the insulating sand during use or transportation is reduced, thereby effectively reducing the sweating of the storage tank, and even frosting and increasing the evaporation rate;

[0035] In addition, there are three fulcrums between the reinforcement member and the outer shell 1 in the present application, which makes the tank stronger.
