Description

Technical Field

[0001] The invention relates to the technical field of isotope separation, in particular to a circulating cooling device for isotope separation. Background Art

[0002] Isotope separation refers to the process of separating different isotopes of the same element. These isotopes have the same atomic number but different numbers of neutrons, so their atomic weights are also different. The principle of isotope separation is mainly based on the subtle differences in the physical and chemical properties of isotopes. These differences include mass, boiling point, diffusion coefficient, reactivity, etc. By utilizing these differences in properties, isotopes can be separated by various methods.

[0003] In the prior art, workers usually use the different movement trajectories of isotopes in an electromagnetic field to separate them, that is, the electromagnetic separation method. The ion acceleration tube is the core component in the working process of the isotope separation device. Its function is to ionize the sample, so that the ions have a certain energy and move in a specific direction. The energy of the ions will be transmitted to the inner wall of the ion acceleration tube to increase its temperature. When the ion acceleration tube is overheated, the material properties inside it may change, resulting in a decrease in ion acceleration performance, which may affect the speed, direction and energy distribution of the ions, and thus affect the quality and stability of the ion beam.

[0015] Preferably, magnets are fixedly mounted on the support frame, and the magnets are arranged on both sides of the ion acceleration pipeline.

[0016] Preferably, an ion curved path pipe is fixedly mounted at the tail end of the ion acceleration pipe, an end of the ion curved path pipe away from the ion acceleration pipe is fixedly connected to a collector, and a detector is fixedly mounted on the collector.

[0018] Preferably, a fixing bracket is fixedly mounted on the flange, and the flange is fixedly mounted on the support frame through the fixing bracket.

[0019] The present invention has at least the following beneficial effects:

[0020] 1. The servo motor of the present invention drives a plurality of wedge-shaped top blocks to rotate through the driving bevel gear and the first driven bevel gear. During the rotation of the wedge-shaped top block, the top block contacts with the top of the wedge-shaped push block. The oblique sides of the two blocks force the wedge-shaped top block to slide in the coolant return bin, thereby driving the coolant to circulate in the U-shaped heat exchange tube, and cooling the tail end of the U-shaped heat exchange tube through the heat exchanger, thereby achieving the purpose of circulating cooling of the ion acceleration pipeline.

[0021] 2. When the coolant enters the curved part of the present invention, the heat exchanger works to cool down the temperature. The coolant passes through the curved part and enters another coolant reflux bin connected to the U-shaped heat exchange tube. As the wedge-shaped top block passes over the first wedge-shaped push block and contacts the second wedge-shaped push block at the mouth of the U-shaped heat exchange tube, the coolant returns to the first coolant reflux bin under the action of the second piston, forming a circulating cooling effect, which can greatly increase the circulation speed of the coolant, thereby greatly improving the cooling effect of the circulating cooling device.

[0022] 3. The present invention uses heat conduction to conduct heat out of the ion acceleration pipe through the heat dissipation copper plate and fins, thereby improving the heat dissipation efficiency. At the same time, the spring can give the piston an elastic force for resetting. When the wedge-shaped top block passes over the first wedge-shaped push block and contacts the second wedge-shaped push block at the mouth of the U-shaped heat exchange tube, the spring can quickly reset the first wedge-shaped push block and the piston. The elastic force of the spring cooperates with the obliquely arranged fins to greatly reduce the resistance to the flow of the coolant.

[0023] 4. When the servo motor drives the first driven bevel gear to rotate through the active bevel gear, the first driven bevel gear drives the circulating pump through the second driven bevel gear and the shaft. The circulating pump introduces the cooling water inside the water tank into the heat exchanger through the conduit. The temperature of the coolant in the U-shaped heat exchange tube drops under the action of the cooling water inside the heat exchanger, and the excess cooling water flows back to the water tank through the outlet pipe on one side of the heat exchanger for natural cooling, which reduces the setting of the power mechanism and can reduce the manufacturing cost of the cooling circulation device.

DETAILED DESCRIPTION

[0033] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0034] like Figure 1 - Figure 7As shown, the circulating cooling device for isotope separation provided in this embodiment comprises a support frame 1 and an ion acceleration pipeline 2 fixedly mounted on the support frame 1, an ion source 3 is fixedly mounted on one end of the ion acceleration pipeline 2, a heat exchanger 4 is fixedly mounted on the other end of the ion acceleration pipeline 2, a servo motor 5 is fixedly mounted on the support frame 1, a driving bevel gear 6 is fixedly mounted on the output end of the servo motor 5, a first driven bevel gear 7 is rotatably connected to the position of the ion acceleration pipeline 2 corresponding to the driving bevel gear 6 through a bearing, and the first driven bevel gear 7 is meshed with the driving bevel gear 6, and the function of the ion source 3 is to ionize the sample so that the ions have a certain energy and enter the ion acceleration pipeline 2;

[0035] A plurality of evenly distributed U-shaped heat exchange tubes 8 are fixedly arranged on the ion acceleration pipeline 2, and both ends of the U-shaped heat exchange tubes 8 are fixedly connected with a coolant return bin 9, and a wedge-shaped push block 10 is slidably arranged inside the coolant return bin 9. A plurality of evenly distributed wedge-shaped top blocks 11 are fixedly arranged on one side of the first driven bevel gear 7 close to the coolant return bin 9, and the wedge-shaped top blocks 11 correspond to the wedge-shaped push blocks 10. The servo motor 5 drives the plurality of wedge-shaped top blocks 11 to rotate through the driving bevel gear 6 and the first driven bevel gear 7, and the wedge-shaped top blocks 11 contact the top of the wedge-shaped push blocks 10 during the rotation process;

[0036] One end of the U-shaped heat exchange tube 8 away from the ion source 3 extends to the interior of the heat exchanger 4. A plurality of evenly distributed heat dissipation copper plates 12 are fixedly arranged on the ion acceleration pipeline 2. The heat dissipation copper plates 12 are arranged between the ion acceleration pipeline 2 and the U-shaped heat exchange tube 8. The oblique edges of the wedge-shaped top block 11 and the wedge-shaped push block 10 abut against each other to force the wedge-shaped top block 11 to slide in the coolant return chamber 9, thereby driving the coolant to circulate in the U-shaped heat exchange tube 8, and cooling the tail end of the U-shaped heat exchange tube 8 through the heat exchanger 4, thereby achieving the purpose of circulating cooling of the ion acceleration pipeline 2;

[0037] Principle: The wedge-shaped push block 10 and the wedge-shaped top block 11 are both provided with inclined surfaces. The contact of the inclined surfaces of the wedge-shaped top block 11 pushes the wedge-shaped push block 10 to slide into the coolant return bin 9. The piston 13 follows the wedge-shaped push block 10 to discharge the coolant in the coolant return bin 9 into the U-shaped heat exchange tube 8. The internal pressure of the U-shaped heat exchange tube 8 increases. When the coolant enters the curved part, the heat exchanger 4 works to cool down. The coolant passes through the curved part and enters another coolant return bin 9 connected to the U-shaped heat exchange tube 8. As the wedge-shaped top block 11 passes over the first wedge-shaped push block 10 and contacts the second wedge-shaped push block 10 at the mouth of the U-shaped heat exchange tube 8, the coolant will return to the first coolant return bin 9 under the action of the second piston 13, forming a circulating cooling effect, which can greatly increase the circulation speed of the coolant, thereby greatly improving the cooling effect of the circulating cooling device.

[0038] Further, such as Figure 1 - Figure 7 As shown, a plurality of evenly distributed fins 121 are fixedly arranged on the heat dissipation copper plate 12, the fins 121 are arranged obliquely, and the fins 121 extend into the interior of the U-shaped heat exchange tube 8, a piston 13 is fixedly arranged on the side of the wedge-shaped push block 10 away from the wedge-shaped top block 11, a spring 14 is fixedly arranged inside the coolant return chamber 9, one end of the spring 14 is fixedly connected to the inner side of the piston 13, and the piston 13 is slidably arranged inside the coolant return chamber 9 through the spring 14;

[0039] Among them, the fins 121 can increase the contact area between the heat dissipation copper plate 12 and the coolant on the one hand, and the fins 121 are arranged obliquely to reduce the resistance of the coolant flow, and can produce a certain turbulence effect when the coolant flows through the fins 121. The turbulence can prevent the formation of a stable boundary layer on the surface of the fins 121. The stable boundary layer will hinder the transfer of heat, and the turbulence can continuously renew the coolant on the surface of the fins 121, so that the heat exchange is more sufficient;

[0040] Principle: The heat inside the ion acceleration pipe 2 is conducted out through the heat dissipation copper plate 12 and the fins 121, thereby improving the heat dissipation efficiency. The spring 14 can provide an elastic force for the piston 13 to reset. When the wedge-shaped top block 11 passes over the first wedge-shaped push block 10 and contacts the second wedge-shaped push block 10 at the mouth of the U-shaped heat exchange tube 8, the spring 14 can quickly reset the first wedge-shaped push block 10 and the piston 13. The elastic force of the spring 14 cooperates with the obliquely arranged fins 121 to greatly reduce the resistance to the flow of the coolant.

[0041] In order to solve the problem of water circulation inside the heat exchanger 4:

[0042] like Figure 1 - Figure 7 As shown, a water tank 15 is fixedly installed on the bottom side of the support frame 1, and a water outlet pipe 41 is fixedly installed on one side of the heat exchanger 4. The water outlet pipe 41 penetrates the support frame 1 and extends to the inside of the water tank 15. A shaft 16 is rotatably provided on the bottom side of the support frame 1. The shaft 16 penetrates the water tank 15 and extends to the other side of the water tank 15. A second driven bevel gear 17 is fixedly installed on the shaft 16, and the upper end of the second driven bevel gear 17 is meshed with the bottom side of the first driven bevel gear 7.

[0043] At the same time, if Figure 1 - Figure 7 As shown, a circulating pump 18 is fixedly installed on the inner bottom side of the support frame 1, and the circulating pump 18 is arranged inside the water tank 15. The shaft 16 penetrates the circulating pump 18 and extends to the outside of the water tank 15. The input end of the circulating pump 18 is fixedly connected to the shaft 16. The outlet of the circulating pump 18 is connected to the inside of the heat exchanger 4 through a conduit, and the inlet of the circulating pump 18 extends to the inner bottom side of the water tank 15 through a conduit.

[0044] In which, when the servo motor 5 drives the first driven bevel gear 7 to rotate through the active bevel gear 6, the first driven bevel gear 7 drives the circulating pump 18 to work through the second driven bevel gear 17 and the shaft 16. The circulating pump 18 introduces the cooling water inside the water tank 15 into the heat exchanger 4 through the conduit. The temperature of the coolant in the U-shaped heat exchange tube 8 drops under the action of the cooling water inside the heat exchanger 4, and the excess cooling water flows back to the water tank 15 through the outlet pipe 41 on one side of the heat exchanger 4 for natural cooling, thereby reducing the setting of the power mechanism and reducing the manufacturing cost of the cooling circulation device.

[0045] Further, if Figure 1 - Figure 7 As shown, a magnet 19 is fixedly mounted on the support frame 1, and the magnets 19 are arranged on both sides of the ion acceleration pipeline 2. An ion curved path pipeline 20 is fixedly mounted on the tail end of the ion acceleration pipeline 2. An end of the ion curved path pipeline 20 away from the ion acceleration pipeline 2 is fixedly connected to a collector 201, and a detector 202 is fixedly mounted on the collector 201.

[0046] Among them, the magnets 19 are arranged on both sides of the ion acceleration pipe 2, which will generate a magnetic field. When the ions are accelerated in the ion acceleration pipe 2 and enter the magnetic field area, according to the Lorentz force law, the ions will be subjected to a force perpendicular to the direction of their velocity and the direction of the magnetic field, specifically:

[0047] F=qvB

[0048] Where F is the Lorentz force, q is the charge of the ion, v is the velocity of the ion, and B is the magnetic field strength.

[0049] This force will cause the movement path of the ions to bend, thereby constraining the ions and preventing them from deviating from the expected trajectory, ensuring that the ions can accurately enter the ion curved path pipe 20. The main function of the collector 201 is to collect ions after acceleration and curved paths. The detector 202 is fixedly mounted on the collector 201 and can detect various characteristics of the ions, thereby providing data support for subsequent analysis.

[0050] In addition, if Figure 1 - Figure 7As shown, flanges 203 are fixedly installed at both ends of the ion acceleration pipeline 2, and the ion acceleration pipeline 2 is fixedly connected to the ion source 3 and the ion curved path pipeline 20 through the flanges 203. A fixed bracket 204 is fixedly installed on the flange 203, and the flange 203 is fixedly installed on the support frame 1 through the fixed bracket 204. The ion acceleration pipeline 2 is usually in a high vacuum state. The flange 203 can prevent outside air from entering the pipeline, thereby ensuring the sealing of ions in the entire transmission path, avoiding ions from colliding with air molecules and losing energy or changing the trajectory of movement. The fixed bracket 204 can effectively reduce the shaking of the device during operation, ensuring that ions can be accelerated and transmitted in a stable pipeline environment, thereby reducing the influence of the external environment on the speed, direction and energy distribution of ions, thereby improving the quality and stability of the ion beam.

[0051] like Figure 1 - Figure 7 As shown, the principle of the circulating cooling device for isotope separation provided in this embodiment is as follows:

[0052] When in use, the sample is ionized through the ion source 3, so that the ions have a certain energy and enter the ion acceleration pipeline 2, and the servo motor 5 is started. The servo motor 5 drives a plurality of wedge-shaped top blocks 11 to rotate through the active bevel gear 6 and the first driven bevel gear 7. During the rotation of the wedge-shaped top block 11, it contacts the top of the wedge-shaped push block 10. The coolant passes through the curved part and enters another coolant reflux chamber 9 connected to the U-shaped heat exchange tube 8. As the wedge-shaped top block 11 passes over the first wedge-shaped push block 10 and contacts the second wedge-shaped push block 10 at the mouth of the U-shaped heat exchange tube 8, the coolant reflux chamber 9 is closed. 0 contact, the coolant will return to the first coolant reflux chamber 9 under the action of the second piston 13, forming a circulating cooling effect. At the same time, the first driven bevel gear 7 drives the circulating pump 18 to work through the second driven bevel gear 17 and the shaft 16. The circulating pump 18 introduces the cooling water in the water tank 15 into the heat exchanger 4 through the conduit. The coolant in the U-shaped heat exchange tube 8 drops in temperature under the action of the cooling water in the heat exchanger 4. The spring 14 can quickly reset the first wedge-shaped push block 10 and the piston 13 to achieve a circulating cooling effect.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
