Existing solid isotope storage devices usually have some technical defects and deficiencies, which affect their performance and application effects.

[0003] In many applications, solid isotopes need to be stored in a low-temperature environment to slow down their radioactive decay and chemical reaction rates. Some solid isotopes are prone to oxidation or hygroscopic reactions when exposed to oxygen and moisture in the air, which in turn affects their purity and stability. However, the current existing technology does not provide a sufficiently complete solution for the storage of solid isotopes in a low-temperature environment. In terms of temperature control, existing storage devices often have problems such as large temperature fluctuations and poor stability, which leads to changes in the performance of isotope materials and instability. At the same time, these devices often lack effective oxygen and moisture isolation measures, which makes some solid isotopes prone to oxidation or hygroscopic reactions when exposed to oxygen and moisture in the air, resulting in performance degradation or even failure.

[0004] Therefore, it is necessary to provide a new type of solid isotope storage device to solve the above problems existing in the prior art. Utility Model Content

[0034] Reference Figure 1-Figure 4 A solid isotope storage device in one embodiment of the utility model comprises a first accommodating chamber 1, a second accommodating chamber 2, a liquid cooling device 3 and a vacuum pump 4; the second accommodating chamber 2 is arranged inside the first accommodating chamber 1, and is used to store solid isotope samples, the liquid cooling device 3 is connected to the first accommodating chamber 1 through a first pipe 61, and the vacuum pump 4 is connected to the second accommodating chamber 2 through a second pipe 62; wherein, the vacuum pump 4 extracts the air in the second accommodating chamber 2 to form a vacuum environment, and the liquid cooling device 3 transports cooling liquid to the first accommodating chamber 1 through the first pipe 61, so that the cooling liquid flows inside the first accommodating chamber 1, and cools down the second accommodating chamber 2 and the solid isotope samples stored therein.

[0035] In this embodiment, by combining the vacuum pump 4 and the liquid cooling device 3, the problems existing in the temperature control and oxygen and moisture isolation of the solid isotope storage device in the prior art are effectively solved. Specifically, the vacuum pump 4 can extract the air in the second accommodating chamber 2 to form a vacuum environment, thereby effectively isolating the solid isotope from the oxygen and moisture in the air, avoiding the occurrence of oxidation or moisture absorption reactions, and ensuring the purity and stability of the solid isotope. At the same time, the liquid cooling device 3 transports the cooling liquid to the inside of the first accommodating chamber 1, so that the cooling liquid flows inside the first accommodating chamber 1, thereby realizing the cooling of the second accommodating chamber 2 and the stored solid isotope sample, effectively slowing down the radioactive decay and chemical reaction rate of the solid isotope, and improving its storage stability and safety. In addition, the storage device of the utility model also has the advantages of simple structure, convenient operation, safety and reliability. Due to the use of liquid cooling for cooling, compared with the traditional gas cooling method, the cooling efficiency is higher, and the temperature can be controlled more accurately, reducing the influence of temperature fluctuations on the performance of solid isotopes. At the same time, the combined use of the vacuum pump 4 and the liquid cooling device 3 enables the equipment to have a better effect in isolating oxygen and moisture, and can meet the special requirements of different solid isotopes during the storage process.

[0036] In summary, the solid isotope storage device of the utility model realizes stable storage and efficient cooling of solid isotopes by combining the vacuum pump 4 and the liquid cooling device 3, solves the problems existing in the prior art, and has broad application prospects and market value.

[0037] It is worth mentioning that the storage device for solid isotopes in this embodiment can also be provided with a plurality of cooling liquid inlets and outlets inside the first accommodating chamber 1, so that the cooling liquid can flow more evenly and reduce the temperature gradient. The cooling liquid can be specially treated pure water or a low conductivity liquid, or it can be a cryogenic liquid such as liquid nitrogen or liquid argon. The specific selection depends on the required cooling temperature range and the properties of the stored solid isotopes. If cryogenic liquids such as liquid nitrogen or liquid argon are used, the temperature of the storage environment can be further reduced, thereby better suppressing the radioactive decay and chemical reactions of the solid isotopes. At the same time, these cryogenic liquids have a lower latent heat of evaporation, which can more effectively absorb and take away the heat generated during the storage process, and maintain a stable low-temperature environment.

[0038] In one embodiment, it also includes a third accommodating chamber 5, which is arranged on the periphery of the first surface of the first accommodating chamber 1, and the second accommodating chamber 2 is arranged on the inner periphery of the first surface of the first accommodating chamber 1; a movable isolation plate is arranged between the second accommodating chamber 2 and the third accommodating chamber 5, and the isolation plate can move between the second accommodating chamber 2 and the third accommodating chamber 5 to separate or connect the second accommodating chamber 2 and the third accommodating chamber 5.

[0039] In this embodiment, since the solid isotope may be affected by the pressure change of the external environment during the process of being placed in the storage device, a third accommodating chamber 5 is provided, and a movable isolation plate is provided between the second accommodating chamber 2 and the third accommodating chamber 5, so that isobaric operation can be effectively achieved. In a specific embodiment, the solid isotope is first placed in the third accommodating chamber 5, and the third accommodating chamber 5 is connected to the second accommodating chamber 2 by adjusting the position of the isolation plate. At this time, since the third accommodating chamber 5 is connected to the second accommodating chamber 2, the vacuum pump 4 is connected to the second accommodating chamber 2 to simultaneously extract the air in the two accommodating chambers to form a uniform vacuum environment, and then the solid isotope is moved to the second accommodating chamber 2, and finally the second accommodating chamber 2 and the third accommodating chamber 5 are separated by moving the isolation plate, which not only ensures that the solid isotope will not be affected by the external pressure change when being placed, but also ensures that the solid isotope is in a vacuum environment during the storage process, effectively preventing the occurrence of oxidation or moisture absorption reaction. In addition, the design of the isolation plate can also be adjusted as needed, for example, it can be set to a sliding type, a rotating type or other forms for easy operation and adjustment. At the same time, the isolation plate can also be made of a material with good sealing performance to ensure that the stability of the vacuum environment is not affected when the second accommodating chamber 2 and the third accommodating chamber 5 are separated or connected.

[0040] In one embodiment, the liquid cooling device 3 and the vacuum pump 4 are arranged in parallel on a side of the third accommodating chamber 5 away from the first accommodating chamber 1 , and the third accommodating chamber 5 is in communication with the vacuum pump 4 .

[0041] In this embodiment, reference Figure 1 , the liquid cooling device 3 and the vacuum pump 4 are arranged in parallel, so that the layout of the whole equipment is more compact and reasonable, and the utilization rate of space is improved. At the same time, since the third accommodating chamber 5 is connected with the vacuum pump 4, it can be ensured that when the solid isotope is placed in the third accommodating chamber 5, the vacuum pump 4 can quickly extract the air in the area, so as to prepare for the subsequent isobaric operation and the formation of the vacuum environment. In addition, the parallel arrangement of the liquid cooling device 3 and the vacuum pump 4 also facilitates the installation, commissioning and maintenance of the equipment, and improves the convenience of use of the equipment. In a specific embodiment, the solid isotope is first placed in the third accommodating chamber 5, and then the vacuum pump 4 is started to extract the air in the third accommodating chamber 5 to form a preliminary vacuum environment. Subsequently, the third accommodating chamber 5 is connected to the second accommodating chamber 2 by moving the isolation plate. At this time, the vacuum pump 4 continues to work, and the air in the two accommodating chambers is extracted at the same time to form a more uniform vacuum environment. Next, the solid isotope is moved from the third accommodating chamber 5 to the second accommodating chamber 2, and the position of the isolation plate is adjusted to separate the second accommodating chamber 2 and the third accommodating chamber 5. At this point, the solid isotope is already in a stable vacuum environment and can be stored for a long time. At the same time, the liquid cooling device 3 starts to work, and transports cooling liquid to the first receiving chamber 1 through the first pipe 61 to cool the second receiving chamber 2 and the stored solid isotope sample. During the entire storage process, the liquid cooling device 3 and the vacuum pump 4 will continue to work to ensure the stability and safety of the storage environment.

[0042] In one embodiment, a movable door 51 is provided at the first end of the third accommodating chamber 5 , a switch for opening and closing the movable door 51 is provided on the movable door 51 , tracks 52 are provided inside the third accommodating chamber 5 , and the isolation plate is provided between the tracks 52 .

[0043] In this embodiment, reference Figure 2 and Figure 3 A movable door 51 is provided at the first end of the third accommodating chamber 5 to facilitate the placement and removal of the solid isotope. A switch is provided on the movable door 51, which can easily control the opening and closing of the door, thereby improving the convenience of operation. At the same time, a track 52 is provided inside the third accommodating chamber 5, and the solid isotope can move smoothly on the track 52, and enter the second accommodating chamber 2 through the cooperation between the guide rail and the isolation plate, which not only ensures the stability and safety of the solid isotope during the movement, but also improves the accuracy and efficiency of the operation.

[0044] In one embodiment, a check valve 7 is further included, one end of the check valve 7 is connected to the second pipeline 62 , and the other end of the check valve 7 is connected to the second accommodating chamber 2 .

[0045] In this embodiment, the check valve 7 is a device for preventing gas from flowing in reverse on the pipe connecting the vacuum pump 4 to the second accommodating chamber 2. When the vacuum pump 4 extracts air from the second accommodating chamber 2, the check valve 7 can ensure that the air can only flow in one direction, that is, from the second accommodating chamber 2 to the vacuum pump 4, so as to avoid the external air from flowing back to the second accommodating chamber 2 through the pipe when the vacuum pump 4 stops working, destroying the vacuum environment that has been formed. This design helps to maintain the vacuum degree in the second accommodating chamber 2 stable, prolong the storage time of solid isotopes, and reduce the risk of solid isotope performance changes caused by air reflux. At the same time, the use of the check valve 7 can also improve the reliability and safety of the entire storage device. When the vacuum pump 4 is working, the check valve 7 can withstand a certain pressure difference to ensure smooth gas flow in the pipe. When the vacuum pump 4 stops working, the check valve 7 can be quickly closed to prevent gas backflow, making the entire storage device more intelligent and reducing the tediousness and error rate of manual operation.

[0046] In one embodiment, reference Figure 3 The liquid cooling device 3 further includes a circulation pump 31 and a liquid storage tank 32 . The circulation pump 31 is connected to the first pipeline 61 , and is connected to the liquid storage tank 32 through a third pipeline 63 .

[0047] In this embodiment, the liquid cooling device 3 also includes a circulating pump 31 and a liquid storage tank 32, so that the cooling liquid can circulate in the first accommodating chamber 1, thereby improving the cooling efficiency and ensuring the continuous supply of the cooling liquid. The circulating pump 31 is connected to the inside of the first accommodating chamber 1 through the first pipeline 61, and the cooling liquid is transported to the inside of the first accommodating chamber 1, so that the cooling liquid wraps the second accommodating chamber 2 to cool the solid isotope. At the same time, the circulating pump 31 is also connected to the liquid storage tank 32 through the third pipeline 63, and the used cooling liquid is transported back to the liquid storage tank 32 for recycling and reuse, thereby realizing the recycling of the cooling liquid and reducing the waste of resources. The design of the liquid storage tank 32 ensures the sufficient supply of cooling liquid and avoids the situation of insufficient cooling liquid during long-term operation. In addition, the liquid storage tank 32 can also filter and purify the cooling liquid to ensure that its quality meets the use requirements and prolong the service life of the liquid cooling device 3. Through the cooperation of the circulating pump 31 and the liquid storage tank 32, the liquid cooling device 3 can continuously and stably provide cooling effect for the solid isotope and ensure the low temperature stability of the storage environment. At the same time, the entire system also has good maintainability. When the cooling liquid needs to be replaced or cleaning and maintenance is required, it can be easily operated through the liquid storage tank 32, thereby reducing maintenance costs and difficulty.

[0048] In one embodiment, a base frame 8 is further included, and the base frame 8 is a hollow structure, and both ends of the base frame 8 are open structures; the first accommodating cavity 1 is arranged on the base frame 8, and the base frame 8 and the first accommodating cavity 1 include a connected state and a disconnected state.

[0049] In this embodiment, the base frame 8 is arranged so that the cooling liquid in the second accommodating chamber 2 can flow out along the base frame 8, so as to facilitate the treatment of the cooling liquid. The base frame 8 adopts a hollow structure design with an open structure at both ends. Such a design not only makes the base frame 8 more lightweight, but also facilitates the circulation and discharge of the cooling liquid. When the base frame 8 is in a connected state with the first accommodating chamber 1, the cooling liquid can flow smoothly into the inside of the base frame 8 and flow out through the opening structure of the base frame 8, so as to achieve the treatment of the cooling liquid. When the circulation of the cooling liquid needs to be disconnected, it is only necessary to adjust the connection state between the base frame 8 and the first accommodating chamber 1 to disconnect the connection relationship between the two, thereby ensuring that the cooling liquid will not continue to flow into the inside of the base frame 8. In an optional embodiment, the connection state can be adjusted by setting a sliding plate between the base frame 8 and the first accommodating chamber 1, or by setting a detachable sealing member between the base frame 8 and the first accommodating chamber 1, and the switching between the connected and disconnected states between the base frame 8 and the first accommodating chamber 1 can be achieved by moving the sliding plate or disassembling and installing the sealing member. In another embodiment, a recovery device is further included, and the recovery device is arranged below the two ends of the opening of the base frame 8, and is used to collect the cooling liquid flowing out of the base frame 8. The recovery device is arranged to better recycle and process the cooling liquid to avoid waste and pollution of the environment. The recovery device can be arranged below the base frame 8, and connected to the base frame 8 through a pipeline or other connection method. When the cooling liquid flows out of the base frame 8, it can directly flow into the recovery device for collection. Components such as filters and liquid storage tanks can be arranged inside the recovery device to filter and purify the recovered cooling liquid, remove impurities and pollutants therein, and then connect to the liquid storage tank 32 so that it can be recycled again, which can not only save resources and reduce the impact on the environment, but also reduce the cost of use and improve the economic benefits of the entire storage device.

[0050] In one embodiment, the vacuum pump 4 is a cylindrical structure, and a plurality of triangular grooves 41 are disposed on the side of the vacuum pump 4 .

[0051] In the present embodiment, the vacuum pump 4 adopts a cylindrical structural design, which not only makes the entire pump body compact and occupies a small space, but also facilitates installation and disassembly. In addition, the cylindrical structure can also effectively disperse the heat generated by the pump body during operation, improve the heat dissipation efficiency, and ensure the stable operation of the pump body. At the same time, a number of triangular grooves 41 are set on the side of the vacuum pump 4. These grooves not only enhance the structural strength of the pump body, improve its pressure resistance and stability, but also can serve as heat dissipation ports, further increase the heat dissipation area, and improve the heat dissipation effect. In addition, the design of the triangular grooves 41 also makes the appearance of the pump body more beautiful and has a certain decorative effect. This structural design not only ensures the efficient and stable operation of the vacuum pump 4, but also improves its service life and reliability, providing a strong guarantee for the long-term safe storage of solid isotopes.

[0052] In one embodiment, reference Figure 3 The liquid cooling device 3 further includes a heat dissipation structure 33 , which is disposed on opposite sides of the circulation pump 31 and abuts against the liquid storage tank 32 .

[0053] In this embodiment, the heat dissipation structure 33 is arranged on opposite sides of the circulation pump 31 and is closely abutted against the liquid storage tank 32, that is, the heat dissipation structure 33 is arranged between the circulation pump 31 and the liquid storage tank 32, which is a semi-enclosed structure with an opening to the first accommodating chamber 1. Such a layout not only ensures the maximization of the heat dissipation effect, but also avoids the waste of space. During the operation of the liquid cooling device 3, the circulation pump 31 continuously delivers the cooling liquid to the inside of the first accommodating chamber 1 to cool the solid isotopes. At the same time, the heat dissipation structure 33 guides the heat generated by the circulation pump 31 and dissipates the heat to the environment through air convection or other heat dissipation methods. At the same time, the heat dissipation structure 33 abuts against the liquid storage tank 32 and can also assist the liquid storage tank 32 in heat dissipation, thereby improving the stability of the cooling liquid in the liquid storage tank 32. This design enables the liquid cooling device 3 to maintain a low temperature while efficiently cooling, thereby avoiding the performance and stability of the device being affected by overheating. The heat dissipation structure 33 can be made of a material with good thermal conductivity, such as a metal or alloy. At the same time, the shape and size of the heat dissipation structure 33 can also be optimized to better adapt to the layout and heat dissipation requirements of the circulation pump 31 and the liquid storage tank 32. In addition, a fan or other heat dissipation auxiliary equipment can be set on the heat dissipation structure 33 to further improve the heat dissipation effect.

[0054] In one embodiment, the liquid cooling device 3 further includes a liquid level sensor, which is disposed inside the liquid storage tank 32 and is used to monitor the liquid level of the cooling liquid in the liquid storage tank 32 in real time.

[0055] In this embodiment, the liquid level sensor is provided to monitor the liquid level of the cooling liquid in the liquid storage tank 32 in real time. Through the liquid level sensor, the remaining amount of cooling liquid in the liquid storage tank 32 can be accurately obtained, so as to determine whether the cooling liquid needs to be supplemented. A display connected to the liquid level sensor can be provided outside the liquid storage tank 32 to display the real-time liquid level of the cooling liquid in the liquid storage tank 32, so that the operator can intuitively understand the use of the cooling liquid and make corresponding supplementary operations in time. In another embodiment, when the liquid level sensor detects that the cooling liquid level is too low, an alarm signal is issued to remind the operator to add cooling liquid in time to avoid affecting the normal operation of the liquid cooling device 3 due to insufficient cooling liquid. At the same time, the liquid level sensor can also be connected to the control system to realize automatic control and monitoring. When the cooling liquid level is lower than the set value, the control system can automatically start the liquid supplementation program to ensure that the cooling liquid in the liquid storage tank 32 is always kept within a suitable range. This design not only improves the reliability and stability of the liquid cooling device 3, but also reduces the difficulty and error rate of manual operation, and improves the operating efficiency of the entire storage device.

[0056] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
