Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, and in particular to a cryogenic storage tank. Background Technology

[0002] A storage tank is a container used to store liquid or gaseous materials. It comes in various shapes, the most common being vertical cylindrical, horizontal cylindrical, and spherical. In the petroleum and chemical industry, large vertical cylindrical storage tanks can store large quantities of liquid materials such as crude oil and gasoline.

[0003] Metallic materials undergo a brittle transition at low temperatures. Taking carbon steel as an example, as the temperature decreases, its toughness decreases significantly, and the material changes from a tough state to a brittle state. When the storage tank is in a low-temperature environment, if it is subjected to external force, ordinary carbon steel materials are prone to brittle fracture, which can lead to the rupture of the storage tank. Therefore, this utility model provides a low-temperature resistant storage tank. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a cryogenic storage tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a low-temperature resistant storage tank, including an outer ring and a temperature control component, the temperature control component including a top plate fixedly connected to the top of the outer ring, a bottom outlet pipe fixedly connected to the bottom of the outer ring, a honeycomb anti-icing grid fixedly connected to the bottom of the top plate, and a temperature-sensitive color-changing patch fixedly connected to the outer side of the outer ring.

[0006] In this embodiment, an inner ring is fixedly connected to the inner side of the bottom end of the top plate, and a partition is provided between the outer ring and the inner ring. In a preferred embodiment, a top switch valve is fixedly connected to the bottom outer side of the outer ring.

[0007] In a preferred embodiment, a bottom switch valve is fixedly connected to the outer top edge of the outer ring.

[0008] In a preferred embodiment, the bottom end of the honeycomb anti-icing grid is fixedly connected to the top end of the bottom outlet pipe.

[0009] In a preferred embodiment, a central rod is fixedly connected inside the top plate.

[0010] In a preferred embodiment, a flip cover is rotatably connected to the outer side of the central rod.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. The top of the honeycomb anti-icing grid is fixed to the bottom of the top plate, and the bottom is fixed to the top of the bottom outlet pipe. The honeycomb structure increases the contact surface. This design achieves the effect of slowing down the large-scale formation and accumulation of ice crystals, thereby preventing ice blockage and structural stress. It solves the problem of pipeline blockage caused by ice crystal accumulation in low-temperature environments, while reducing structural stress and avoiding brittle fracture of carbon steel materials caused by stress. This ensures the stability of the low-temperature liquid state inside the storage tank and the smooth flow of pipelines.

[0012] 2. When the external ambient temperature changes, the color of the temperature-sensitive color-changing patch fixedly connected to the outer edge of the ring changes. This design provides an intuitive temperature status indication, allowing operators to understand the impact of ambient temperature on the storage tank in a timely manner. It enables operators to monitor the impact of changes in external ambient temperature on the storage tank in real time, so as to take timely measures to prevent the carbon steel material from undergoing brittle transformation due to excessively low ambient temperature, thereby avoiding the tank from rupturing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, this embodiment provides a technical solution: a cryogenic storage tank, including an outer ring 1, a central rod 6 fixedly connected inside a top plate 21, and a flip cover 5 rotatably connected to the outside of the central rod 6; the outer ring 1 serves as the main structure of the storage tank, providing sufficient space and structural strength to ensure the overall shape and stability of the storage tank; the top plate 21 is located at the top of the storage tank, sealing the top opening of the tank to prevent leakage of stored materials, and providing a foundation for the installation and connection of other components; it is fixedly connected to the top of the outer ring 1 to ensure the stability of the storage tank. The top is sealed and structurally intact. The central rod 6 is fixedly connected to the inside of the top plate 21, providing support and a central axis for rotation. A flap 5 is rotatably connected to the outside of the central rod 6, allowing the flap 5 to rotate around the central rod 6. The flap 5 is used to close or open the opening at the top of the tank. When it is necessary to add substances to the tank or to perform internal operations, the flap 5 can be opened. Under normal storage conditions, the flap 5 is closed to maintain the sealing of the tank. The opening and closing of the flap 5 is convenient and quick, improving the operability and ease of use of the tank.

[0024] It also includes a temperature control component 2, which includes a top plate 21 fixedly connected to the top of the outer ring 1, a bottom outlet pipe 22 fixedly connected to the bottom of the outer ring 1, a honeycomb anti-icing grille 23 fixedly connected to the bottom of the top plate 21, and a temperature-sensitive color-changing patch 24 fixedly connected to the outer side of the outer ring 1; wherein, an inner ring 4 is fixedly connected to the inner side of the bottom of the top plate 21, a partition 27 is provided between the outer ring 1 and the inner ring 4, a top switch valve 26 is fixedly connected to the bottom of the outer side of the outer ring 1, a bottom switch valve 25 is fixedly connected to the top of the outer side of the outer ring 1, and the bottom of the honeycomb anti-icing grille 23 is fixedly connected to the top of the bottom outlet pipe 22;

[0025] The temperature control component 2 includes a top plate 21, a bottom outlet pipe 22, a honeycomb anti-icing grille 23, and a temperature-sensitive color-changing patch 24. Together, they maintain a low-temperature environment inside the storage tank and prevent ice formation. The top plate 21, as part of the temperature control component 2, is fixedly connected to the top of the outer ring 1, providing a mounting base for other temperature control components 2. The bottom outlet pipe 22 is fixedly connected to the bottom of the outer ring 1, serving as a channel for discharging stored materials from the tank, facilitating the output of the stored materials to other locations where needed. The honeycomb anti-icing grille 23 is fixedly connected to the bottom of the top plate 21. Its unique honeycomb structure increases the contact area with the stored materials, preventing the large-scale formation and accumulation of ice during temperature changes. When the temperature of the stored materials is low, the honeycomb anti-icing grille 23 provides some insulation, reducing heat transfer; while during temperature fluctuations, it alleviates the pressure on the tank structure caused by ice formation. The temperature-sensitive color-changing patch 24 is fixedly connected to the outside of the outer ring 1, visually reflecting changes in the external ambient temperature of the tank through color changes. When the ambient temperature rises or falls to a certain level, the patch color changes accordingly, providing operators with a simple and intuitive means of temperature monitoring. The inner ring 4 is fixedly connected to the bottom inner side of the top plate 21, and a partition 27 is provided between it and the outer ring 1. The inner ring 4 and the outer ring 1 together form a double-layer structure of the storage tank, which enhances the heat preservation performance and structural stability of the storage tank. The partition 27 is set between the outer ring 1 and the inner ring 4. Utilizing the heat insulation performance of the partition 27, the heat transfer between the inside of the storage tank and the external environment is effectively reduced. Because there is no medium such as air in the partition 27 for heat conduction and heat convection, the heat loss or entry into the storage tank can be greatly reduced, thereby maintaining a low-temperature environment inside the storage tank and reducing the temperature change of the stored items due to heat exchange. The top switch valve 26 is fixedly connected to the bottom outer side of the outer ring 1 and is mainly used to control the input or output of the stored items. The bottom switch valve 25 is fixedly connected to the top outer side of the outer ring 1 and is used to release cold air by switching the bottom switch valve 25 when the temperature of the partition 27 is too high.

[0026] Working principle:

[0027] like Figure 1 - Figure 5 As shown:

[0028] In use: First, the operator rotates the flip cover 5, which in turn rotates the flip cover 5 around the central rod 6 fixed inside the top plate 21, thereby opening or closing the top opening of the storage tank, facilitating the addition of stored items or internal maintenance. Second, the partition 27, located between the outer ring 1 and the inner ring 4 fixed to the inner side of the bottom of the top plate 21, utilizes its vacuum or insulation material properties to block external heat from entering the tank, thereby maintaining a stable low-temperature environment inside the storage tank. Simultaneously, the honeycomb anti-icing grid 23, with its top fixedly connected to the bottom of the top plate 21 and its bottom fixedly connected to the top of the bottom outlet pipe 22, increases the contact surface through its honeycomb structure, thus mitigating the large-scale formation and accumulation of ice crystals. To prevent ice blockage and structural stress, the internal cryogenic liquid state is stabilized and the pipeline is unobstructed. When the temperature of the interlayer 27 rises abnormally, the operator opens the bottom switch valve 25 located at the top of the outer ring 1. Because its fixed connection position is in the top area of ​​the storage tank, it can release the core cold air inside the storage tank into the space of the interlayer 27, thereby reducing the temperature of the interlayer. This achieves active adjustment of the interlayer temperature and enhances the overall insulation effect. First, the external ambient temperature changes, which in turn causes the color of the temperature sensing color-changing patch 24 fixedly connected to the outer ring 1 to change, thus providing a clear temperature status indication. This allows the operator to understand the impact of the ambient temperature on the storage tank in a timely manner, achieving convenient external temperature monitoring.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
