Description

Technical Field

[0001] This utility model relates to the field of separation devices, and in particular to a separation device for isotope ions. Background Technology

[0002] Isotope ion separation technology plays a crucial role in nuclear physics experiments, radiotherapy, and geological dating. In nuclear physics research, high-purity isotopes are fundamental to exploring the properties of nuclides; in the medical field, specific isotopes can be used for disease diagnosis and targeted therapy; in geological research, isotope ratio analysis can provide important evidence for stratigraphic evolution. Therefore, efficient and stable isotope ion separation devices are essential for carrying out work in these fields.

[0003] Existing isotope ion separation devices suffer from significant deficiencies in the installation and sealing of the ion source. Traditional installation methods require multiple bolts for step-by-step fixing, which is cumbersome and time-consuming. Furthermore, the difficulty in uniformly controlling the force at multiple connection points easily leads to gaps between the sealing components and the tank interface, making subsequent vacuum extraction difficult. Even if a vacuum is achieved, continuous leakage disrupts the stable environment for ion separation. Simultaneously, the ion source's electrical connection method has flaws. Traditional electrode connections require precise alignment in a non-vacuum state, which is complex. Due to the lack of precise positioning and a stable structure, once the device enters vacuum operation, vibrations or temperature changes can alter the contact state between the electrodes and the ion source, leading to poor contact. This results in unstable rubidium ion release power supply and large fluctuations in release volume, severely impacting the separation accuracy and efficiency of isotope ions and failing to meet the high-efficiency and precise separation requirements of relevant fields.

[0004] In response to this technical problem, this application proposes a device for separating isotope ions. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] Reference Figures 1-3 This utility model provides an embodiment of an isotope ion separation device, comprising a tank 1, a slider 2 slidably connected to the bottom inner side of the tank 1, a spring 3 at one end of the slider 2, a connecting rod 4 rotatably connected to the top end of the slider 2, a sealing ring 5 rotatably connected to the other end of the connecting rod 4, a baffle 6 at the lower side of the sealing ring 5, a positioning groove 15 at the top of the baffle 6, a spring 7 at the lower side of the baffle 6, the outer wall of the spring 7 being disposed inside the tank 1, a positioning groove 8 at the bottom of the tank 1, a power supply device 11 fixedly connected to the bottom of the tank 1, a rotating groove 9 at the top of the power supply device 11, a tank cover 14 at the top of the tank 1, a sealing block 13 fixedly connected to the bottom of the tank cover 14, the outer wall of the sealing block 13 being disposed inside the tank 1.

[0020] Specifically, in the rubidium ion separation process, a suitable amount of high-purity rubidium chloride is first calcined at high temperature, and after cooling, it forms a working substance, which is then loaded into the ion source 12. The ion source 12 and receiver 20 are assembled on the device. A vacuum is drawn by the vacuum device 18, and the rubidium ions in the ion source 12 are excited by the power supply device 11. The rubidium ions in the ion source 12 are then separated by the separator 17 and the water cooling device 19, and finally collected by the receiver 20 for further purification. During the assembly of the ion source 12, insufficient sealing often affects the working efficiency of the device and the purity of the collected rubidium ions. Therefore, it is placed on the top of the baffle 6 and pressed down, so that the locking block 10 at the bottom of the ion source 12 is engaged in the corresponding position in the positioning groove 15 at the bottom of the tank 1. When the baffle 6 is not pressed down, under the pushing force of the spring 3, the slider 2 approaches and stops at the center position near the bottom of the tank 1. At this time, the connecting rod 4 is in an inclined state, so that the sealing ring 5 connected to it is located below. The bottom periphery of the baffle plate 6 is arc-shaped. As the ion source 12 continues to descend, causing the baffle plate 6 to move downwards, the arc-shaped periphery of the bottom of the baffle plate 6 will abut against the connecting rod 4, using its arc-shaped surface to apply a thrust that expands outwards towards the tank body 1. As the baffle plate 6 continues to descend, it will compress the second spring 7 and force the connecting rod 4 to move outwards continuously and gradually tend towards upright. The outward and straightening movement of the connecting rod 4 overcomes the force of the first spring 3, causing the slider 2 to gradually move outwards towards the tank body 1. As the connecting rod 4 changes from an inclined state to a near-upright state, the sealing ring 5 is lifted. When the ion source 12 descends to the limit, the locking block 10 passes through the positioning groove 8 at the bottom of the tank body 1 and finally slides into the rotating groove 9. At this time, the baffle plate 6 continues to abut against the connecting rod 4, making the connecting rod 4 completely upright or nearly upright, thereby ensuring that the sealing ring 5 is lifted to the highest position and pressed tightly against the interface at the top of the tank body 1. Next, the ion source 12 is rotated, causing the locking block 10 to rotate 90 degrees within the rotating groove 9. When the locking block 10 reaches its limit, it is locked inside the end of the rotating groove 9 and the bottom of the tank body 1, preventing it from being lifted upwards, thus limiting the ion source 12. The tank lid 14 is then placed on top. The sealing block 13 at the bottom of the lid 14 precisely matches the shape of the already lifted and compressed sealing ring 5, jointly pressing the lid tightly. Simultaneously, sealing material is also provided between the bottom of the lid 14 and the top of the tank body 1 to ensure a complete seal at the joint surface. The lid 14 is then tightly connected and fixed to the tank body 1 using a flange. Simultaneously, the sealing block 13 presses downwards against the ion source 12, preventing it from rotating. This achieves quick and reliable installation of the ion source 12 and a complete seal of the tank body 1, providing the necessary conditions for subsequent safe and efficient vacuum extraction and ion separation operations.

[0021] Reference Figures 2-4The rotating tank 9 has a locking block 10 inside, with an ion source 12 fixedly connected to its top. The outer wall of the ion source 12 is located inside the tank body 1. A baffle 6 is positioned at the bottom of the ion source 12 to position and support it. A spring 3 is located inside the tank wall of the tank body 1 to rebound the slider 2. A separator 17 is fixedly connected to the right side of the tank body 1, a water cooling device 19 is fixedly connected to the right side of the separator 17, a receiver 20 is fixedly connected to the right side of the water cooling device 19, and a vacuum device 18 is fixedly connected to the rear side of the separator 17. A control system 16 is fixedly connected to the front side of the power supply device 11, and the other end of the control system 16 is fixedly connected to the front side of the separator 17 to control the operation of each device.

[0022] Specifically, during the operation of the ion source 12, an electric current is required to excite the ions within it for emission. Traditional methods are relatively complex, and the docking method is not conducive to maintaining a vacuum state during operation. Therefore, there is an electrode at the bottom of the locking block 10 that provides power support to the ion source 12. When the locking block 10 falls into the rotating groove 9 and rotates, it connects with the electrode at the top of the power supply device 11 inside the rotating groove 9. Magnets are used to position the electrode inside the rotating groove 9, so that the locking block 10 can perfectly contact and connect with the electrode at the top of the power supply device 11 in the rotating groove 9 after rotating to the limit. Furthermore, after the can lid 14 at the top of the canister 1 is installed, the sealing block 13 will tightly press against the top of the ion source 12, preventing the ion source 12 from rotating or displacing. This allows the electrode at the bottom of the locking block 10 to be firmly connected with the electrode at the top of the power supply device 11 in the rotating groove 9, enabling rapid power supply to the ion source 12. The control system 16 controls the current applied to the ion source 12 by the power supply device 11, thereby controlling the release of rubidium ions from the ion source 12.

[0023] Working principle: In the rubidium ion separation process, a suitable amount of high-purity rubidium chloride is first calcined at high temperature and cooled to form a working substance. After being loaded into the ion source 12, it is placed on the top of the baffle 6 and pressed down, causing the locking block 10 to engage with the corresponding position in the positioning groove 15. At this time, the slider 2, under the action of the spring 3, gathers towards the center of the bottom of the tank 1 to the limit position, and the connecting rod 4 is tilted, causing the sealing ring 5 to move down to the limit position. As the ion source 12 descends, the outer arc of the bottom of the baffle 6 abuts against the connecting rod 4 and causes it to expand outwards from the tank 1. The slider 2 moves outwards accordingly, the connecting rod 4 gradually straightens, and the sealing ring 5 rises. When the ion source 12 descends to the limit position, the locking block 10 falls into the rotating groove 9 through the positioning groove 8, and the baffle 6 abuts against the connecting rod 4, causing the sealing ring 5 to rise to the top interface inside the tank 1 and be pressed tightly. The rotating ion source 12 causes the locking block 10 to rotate within the rotating groove 9 and be locked by the bottom of the tank body 1 to achieve positioning. The tank cover 14 is then closed, so that the sealing block 13 fits with the sealing ring 5, and the tank cover 14 and the tank body 1 are connected by sealing material and flange to achieve complete sealing. At the same time, after the bottom electrode of the locking block 10 falls into the rotating groove 9 and rotates, it connects with the electrode at the top of the power supply device 11 within the rotating groove 9 (magnets around the electrode within the rotating groove 9 assist in positioning). After the tank cover 14 is sealed, it prevents the ion source 12 from rotating and shifting to ensure that the electrode connection is firm. The power supply device 11 supplies power to the ion source 12 through the electrode to stimulate rubidium ion emission. Under the control of the control system 16, the rubidium ions pass through the separator 17 and the water cooling device 19 in sequence, and are finally collected by the receiver 20 to prepare for subsequent purification processing.
