Description

Technical Field

[0001] This invention belongs to the field of radioactive isotope production technology, specifically relating to an automatic feeding and discharging device and a target feeding and discharging method for an exothermic chamber. Background Technology

[0002] In the production of radioisotopes, to exponentially increase the yield of radioisotopes produced by the accelerator, a "multi-target + stacked target + beam scanning" scheme can be used for target bombardment. This involves evenly distributing thermal deposition across multiple target sheets and uniformly modulating the beam. By irradiating multiple target sheets in a single pass, the power areal density on the target sheets decreases exponentially. The target sheets are primarily fixed within the heat-exposed chamber by a fixed structure arranged in a specific spatial pattern. To reduce the difficulty of transporting the target sheets inside and outside the heat-exposed chamber, the target sheet is typically defined as the smallest transfer unit for feeding and discharging. When the target sheet is discharged, the fixed structure remains within the heat-exposed chamber for reuse. Assembly and disassembly of the target sheet and the fixed structure are completed within the heat-exposed chamber.

[0003] Currently, target plates can be transferred using multiple sets of master-slave robotic arms. A viewing window is installed on the exothermic chamber, allowing operators to assemble and disassemble the target plates with the fixed structure using the viewing window and the master-slave robotic arms. Since the target plates exhibit high radioactivity after being bombarded by a high-power beam, multiple target plates need to be disassembled and discharged in batches to reduce the cost of transferring activated target plates and the shielding cost of the downstream separation system.

[0004] However, handling the disassembly and unloading of a large number of target pieces at high frequency is an extremely challenging task for manual operation. Moreover, the accuracy of the operation depends on the operator's proficiency, and repeatability is difficult to guarantee. Manual operation cannot complete the disassembly and unloading of target pieces multiple times with high precision. Summary of the Invention

[0005] To address the shortcomings of the prior art, this invention provides an automatic feeding and discharging device and target feeding and discharging method for an exothermic chamber. By cooperating with an irradiation component, an encapsulation component, and a shielding discharging component, the automatic discharging of the target can be achieved, ensuring the accuracy, stability, and safety of the target disassembly and discharging operations.

[0006] The technical effects to be achieved by this invention are realized through the following technical aspects: In a first aspect, the present invention provides an automatic feeding and discharging device for an exothermic chamber, comprising an operating table; a transfer tank for storing and transferring target sheets; an encapsulation assembly disposed on the operating table, the encapsulation assembly opening or closing the transfer tank; a shielding discharge assembly disposed on one side of the encapsulation assembly, the shielding discharge assembly including a shielding tank and a transfer roller conveyor, the transfer tank being placed inside the shielding tank, the transfer roller conveyor conveying the shielding tank to discharge the target sheet; and an irradiation-resistant moving component disposed between the encapsulation assembly and the shielding discharge assembly, the irradiation-resistant moving component being used to grip the target sheet and the transfer tank.

[0007] In some implementations, the transfer container includes a container body and a lid, which are detachably connected. The encapsulation assembly includes: a rotating structure disposed on the operating table, the rotating structure clamping the container body and driving the container body to rotate; and a limiting structure disposed on one side of the rotating structure, the limiting structure restricting the rotation of the lid body. The container body rotates relative to the lid body to open or close the transfer container.

[0008] In some implementations, the rotating structure includes a chuck, in which the can is placed, the chuck clamps the can, and drives the can to rotate.

[0009] In some implementations, the cover has a perforated hole, and the limiting structure includes: a lifting plate; a lifting drive connected to the lifting plate, the lifting drive driving the lifting plate to move to one side of the cover; a flip cover rotatably mounted on the lifting plate, the flip cover having a limiting pin, which, when inserted into the perforated hole, restricts the rotation of the cover; and a flip drive connected to the flip cover, which, when the lifting plate moves to one side of the cover, drives the flip cover to flip so that the limiting pin is inserted into the perforated hole.

[0010] In some implementations, the operating platform is provided with a discharge port for discharging material from the transfer tank. A first shielding cover is rotatably installed on the operating platform at the discharge port. The first shielding cover seals the discharge port. When the first shielding cover is opened, the shielded tank receives the transfer tank at the discharge port.

[0011] In some implementations, the shielding tank includes an outer tank and an inner tank, with the inner tank located inside the outer tank. The transfer tank is placed inside the inner tank for transfer and discharge. The inner tank is provided with a second shielding cover for sealing the inner tank. A lifting structure for driving the inner tank to move up and down is provided on one side of the outer tank. The lifting structure passes through the outer tank via the transfer roller conveyor and lifts the inner tank to the discharge port. When the lifting structure lifts the inner tank, the first shielding cover aligns with the second shielding cover, and the first shielding cover drives the second shielding cover to rotate synchronously.

[0012] In some implementations, a shielding compensation structure is provided between the operating platform and the shielding tank, and the shielding compensation structure blocks or opens the discharge port on the outside of the operating platform.

[0013] In some implementations, the operating table is provided with a feed track for feeding the target sheet.

[0014] In some implementations, a fixing frame and an integrated component for fixing the target piece are also included, wherein the target piece is inserted into the integrated component; the fixing frame is provided with grippers that grip or release the integrated component.

[0015] Secondly, the present invention provides a target plate feeding and discharging method, employing the aforementioned automatic feeding and discharging equipment within an exothermic chamber, the target plate feeding and discharging method comprising the following steps: The radiation-resistant moving component grasps the transfer container, and the transfer container is moved to the encapsulation component. The transfer container is opened by the encapsulation assembly, the radiation-resistant moving part picks up the target sheet and places it into the transfer container, and the encapsulation assembly closes the transfer container. The radiation-resistant mobile component is moved from the transfer tank to the shielding tank, and the shielding tank is conveyed by the transfer roller conveyor, and the target sheet is discharged.

[0016] In summary, the present invention has at least the following advantages: 1. The automatic feeding and discharging equipment in the exothermic chamber provided by this invention includes an irradiation moving component that grasps a transfer tank and moves it to an encapsulation component. The encapsulation component opens the transfer tank, allowing the irradiation moving component to disassemble the bombarded target sheet into the transfer tank. The transfer tank holds the target sheet, enabling batch transfer to reduce the frequency of operation of the irradiation moving component and thus improve the target sheet discharge efficiency. After the target sheet is disassembled, the encapsulation component closes the transfer tank, sealing the target sheet within it for transport. The radiation-resistant moving component then transfers the transfer tank to a shielding tank, and a conveyor roller conveyor transports the shielding tank to discharge the target sheet.

[0017] The target sheet is automatically disassembled and unloaded through the cooperation of the irradiation moving part, the encapsulation component and the shielding unloading component. Compared with the traditional target sheet disassembly and unloading operation, it can match the "multi-target point + stacked target + beam scanning" scheme, meet the operation requirements of high power, high frequency and high precision scenarios. Moreover, in the small space of the heat-exposed chamber, the automatic feeding and unloading equipment in the heat-exposed chamber can also successfully complete the disassembly and unloading operation of the target sheet, ensuring the repeatability and accuracy of the operation.

[0018] 2. The target feeding and discharging method provided by the present invention automates the entire target discharging process, eliminating the need for operators to perform multiple repetitive operations through master and slave robotic arms. The automated discharging process has the advantages of high safety, high accuracy, good stability, and low transportation cost. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of the present invention.

[0028] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0029] Example 1: Please see Figures 1-3 and Figure 5 The automatic feeding and discharging device for the heat-exothermic chamber of the present invention can realize the fully automated operation of the assembly, disassembly and discharge of the target plate 8, so as to improve the accuracy and stability of the operation.

[0030] Please see Figure 1 The automatic feeding and discharging device for the exothermic chamber of the present invention includes an operating table 1 and a transfer tank 2 for storing and transferring target plates 8. Specifically, the operating table 1 can be set in an area far away from the irradiation point of the target plate 8 to reduce the absorbed dose of the automatic feeding and discharging device for the exothermic chamber, extend its service life, and reduce maintenance costs.

[0031] The transfer tank 2 loads the target wafers 8 during the target wafer discharge process, enabling batch discharge of the target wafers 8 and reducing the impact of the high radioactivity exhibited after bombardment, thus ensuring the safety of the discharge operation. Specifically, the transfer tank 2 can be made of titanium alloy. In some specific embodiments, the operating table 1 is provided with a storage point 12 for storing the transfer tank 2, which can be temporarily stored at the storage point 12 when not in use.

[0032] The control panel 1 is equipped with a sealing assembly 3 for opening or closing the transfer tank 2. A shielding discharge assembly 4 is located on one side of the sealing assembly 3. Please refer to [link / reference]. Figure 5 The shielding discharge assembly 4 includes a shielding tank 42, a transfer tank 2 is placed inside the shielding tank 42, and a transfer roller 46 transports the shielding tank 42 to discharge the target sheet 8. An irradiation-resistant moving part for gripping the target sheet 8 and the transfer tank 2 is provided between the encapsulation assembly 3 and the shielding discharge assembly 4.

[0033] Please see Figure 1 In some specific embodiments, the radiation-resistant moving component is a radiation-resistant robotic arm 5. The radiation-resistant robotic arm 5 and the packaging assembly 3 can be connected to the inner wall of the heat-exposed chamber via the operating table 1 for easy maintenance. The working radius of the radiation-resistant robotic arm 5 covers the area where the packaging assembly 3 and the shielding discharge assembly 4 are located. The radiation-resistant robotic arm 5 includes quick-change grippers, which enable it to automatically perform operations such as gripping, inserting, pulling, filling, and transferring the target sheet 8 in a strong radiation environment.

[0034] Please see Figures 1-3 In some specific embodiments, the automatic loading and unloading device for the radioactive and radiothermal chamber of the present invention further includes a fixing frame 6 and an integrated component 62 for fixing the target plate 8. The target plate 8 is inserted into the integrated component 62, which serves as a carrier structure for the transfer and irradiation of the target plate 8. This integrated component 62 is reusable and helps reduce radioactive solid waste at the source. The target plate 8 is set as the smallest unit for loading and unloading, which can significantly reduce transfer costs. Specifically, the integrated component 62 includes a carrier plate for placing the target plate 8. The carrier plate has multiple layers, each layer serving as a single target point. Multiple slots are provided on the carrier plate, and the target plate 8 is inserted into the slots for fixing. Multiple target plates 8 are stacked along the beam injection direction within a single target point. During target plate assembly, the radiation-resistant robot 5 can insert multiple target plates 8 into the corresponding slots to integrate them onto the integrated component 62. During target plate disassembly, the radiation-resistant robot 5 can sequentially pull multiple target plates 8 out of the integrated component 62, making the operation convenient.

[0035] The fixed frame 6 is equipped with a gripper 61, which grips or releases the integrated component 62. When the integrated component 62 is fixed on the fixed frame 6 by the gripper 61, the fixed frame 6 and the gripper 61 support the integrated component 62 and assist the integrated component 62 in positioning, providing a reliable reference for the radiation-resistant robot 5. The radiation-resistant robot 5 can perform assembly or disassembly operations on the target 8. The fixed frame 6 and the gripper 61 ensure the stability of the integrated component 62.

[0036] In some other specific embodiments, the operating table 1 is provided with a feeding track 7 for the target pieces 8 to enter the heat dissipation chamber. The feeding track 7 guides the target pieces 8 to be smoothly delivered to the surface of the operating table 1. Furthermore, a glove box may be provided on one side of the feeding track 7, and the glove box cooperates with the feeding track 7 to realize the feeding of multiple target pieces 8 in a single batch.

[0037] During the assembly of the target piece 8, the target piece 8 is first transported to the operating table 1 via the feeding track 7. Specifically, a master-slave robot or a powered robot is installed in the heat-exposed chamber to transfer the integrated component 62 and the target piece 8 between the irradiation area and the operating table 1. The master-slave robot or the powered robot places the empty integrated component 62 on the fixing frame 6, and the gripper 61 clamps and fixes the integrated component 62. The radiation-resistant robot 5 transfers the target piece 8 from the feeding track 7 to the integrated component 62 and picks up the target piece 8 and inserts it into the integrated component 62 in sequence until all target pieces 8 are assembled. Then, with the help of the master-slave robot or the powered robot in the heat-exposed chamber, the integrated component 62 is transferred to the irradiation area, where the accelerator bombards the target piece 8.

[0038] During the disassembly and unloading of target plate 8, the master-slave or powered robot in the heat-exothermic chamber transfers the integrated component 62 and target plate 8 to the fixed frame 6 within the irradiation area. The fixed frame 6 supports and fixes the integrated component 62 via grippers 61. The radiation-resistant robot 5 picks up the transfer tank 2 stored at storage point 12 and moves it to the encapsulation assembly 3. The encapsulation assembly 3 opens the transfer tank 2, and the radiation-resistant robot 5 disassembles the target plates 8 one by one from the integrated component 62 and transfers them one by one into the transfer tank 2, thus completing the disassembly of the target plates 8. The encapsulation assembly 3 closes the transfer tank 2, and the radiation-resistant robot 5 picks up the transfer tank 2 to move it into the shielding tank 42. The transfer roller 46 transports the shielding tank 42, and the target plate 8 is discharged from the transfer tank 2 along with the shielding tank 42.

[0039] The assembly, disassembly, and unloading of the target plate 8 within the radiation and heat-exposing chamber are fully automated. Moreover, the entire process can be performed within the confined space of the radiation and heat-exposing chamber. Compared with the traditional method of manually operating master and slave robots for repetitive operations, this method is beneficial to improving the positioning accuracy of the operation and ensuring the stability of multiple operations.

[0040] Example 2: The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the encapsulation component 3 of the present invention. Please refer to [link to embodiment 1].Figure 4 .

[0041] The transfer tank 2 in this embodiment includes a tank body 21 and a cover 22. The tank body 21 and the cover 22 are detachably connected. In some specific embodiments, the cover 22 is provided with a slot, which is specifically an L-shaped hole. The tank body 21 is provided with a connecting pin, which passes through the slot. By rotating the tank body 21, the connecting pin is disengaged from the slot, and the tank body 21 and the cover 22 are separated from each other.

[0042] The packaging assembly 3 includes a rotating structure disposed on the operating table 1. The rotating structure clamps the can 21 and drives the can 21 to rotate. In some specific embodiments, the rotating structure includes a chuck 31, in which the can 21 is placed. The chuck 31 clamps the can 21 and drives it to rotate. Furthermore, the chuck 31 is driven by a rotary drive component for driving the rotation of the chuck 31. The rotary drive component is preferably, but not limited to, a motor.

[0043] A limiting structure 32 is provided on one side of the rotating structure to restrict the rotation of the cover 22. The chuck 31 drives the tank 21 to rotate relative to the cover 22 to open or close the transfer tank 2. In some specific embodiments, the cover 22 has a hollow hole 221. The limiting structure 32 includes a lifting plate 321, which is connected to a lifting drive component 322. The lifting drive component 322 drives the lifting plate 321 to move up and down relative to the operating table 1.

[0044] A flip cover 323 is rotatably mounted on the lifting plate 321. A limiting pin 324 is provided on the flip cover 323. When the limiting pin 324 is inserted into the hollow hole 221, it restricts the rotation of the cover 22. The flip cover 323 is driven by a flipping drive 325. The flipping drive 325 is preferably, but not limited to, a cylinder. Specifically, the flip cover 323 is provided with a flipping shaft, which is rotatably mounted on the lifting plate 321. The flipping shaft is driven by the output end of the flipping drive 325. When the flipping drive 325 drives the flipping shaft to rotate, it can drive the flip cover 323 to rotate synchronously. When the lifting plate 321 moves to one side of the cover 22, the flipping drive 325 drives the flip cover 323 to rotate, so that the limiting pin 324 is inserted into the hollow hole 221.

[0045] When the radiation-resistant robotic arm 5 transfers the transfer canister 2 to the encapsulation assembly 3, the transfer canister 2 is first placed into the chuck 31, which clamps the canister 21. The lifting drive 322 drives the lifting plate 321 to rise away from the operating table 1. The lifting plate 321 drives the flip cover 323 to move to one side of the cover 22. The flip drive 325 drives the flip cover 323 to flip via the flip shaft, so that the flip cover 323 rotates to the top of the cover 22, aligning the limiting pin 324 with the hollow hole 221. Then, the lifting drive 322 drives the flip cover 323 to descend via the lifting plate 321, and the flip cover 323 drives the limiting pin 324 to insert into the hollow hole 221 to restrict the rotation of the cover 22.

[0046] Subsequently, the chuck 31 drives the tank 21 to rotate relative to the cover 22, and the connecting pin slides along the slot to unlock. The lifting drive 322 drives the lifting plate 321 and the flip cover 323 to rise relative to the cover 22, the limiting pin 324 disengages from the hollow hole 221, the flip drive 325 drives the flip cover 323 to flip and reset, and the lifting drive 322 then drives the flip cover 323 and the lifting plate 321 to descend and reset. At this time, the cover 22 can be separated from the tank 21 by the radiation-resistant robot 5, and the transfer tank 2 is in the open state. Specifically, the operating table 1 is provided with a temporary storage seat 33 for temporarily storing the cover 22. The radiation-resistant robot 5 grabs the cover 22 and places it on the temporary storage seat 33. The radiation-resistant robot 5 then picks up the target piece 8 and disassembles multiple target pieces 8 from the integrated part 62 in sequence. The target pieces 8 are placed into the tank 21.

[0047] Once the tank 21 is filled with the target sheet 8, the radiation-resistant robotic arm 5 grasps the cover 22 on the temporary storage seat 33 and closes the cover 22 onto the tank 21. The lifting drive 322 drives the lifting plate 321 and the flip cover 323 to rise relative to the operating table 1. The flip drive 325 drives the flip cover 323 to flip over to above the cover 22. The lifting drive 322 then drives the lifting plate 321 and the flip cover 323 to descend a certain height, causing the limiting pin 324 to re-insert into the hollow hole 221, and the cover 22 is limited by the limiting pin 324. The chuck 31 drives the tank 21 to rotate in the opposite direction relative to the cover 22, and the connecting pin enters the slot, putting the transfer tank 2 in the closed state. After the lid 22 seals the can 21, the lifting drive 322 drives the lifting plate 321 and the flip cover 323 to rise, the limiting pin 324 disengages from the drop hole, the flip drive 325 drives the flip cover 323 to flip and reset, and the lifting drive 322 drives the lifting plate 321 and the flip cover 323 to descend and reset. The target plate 8, through the coordinated action of the encapsulation assembly 3 and the radiation-resistant robotic arm 5, completes the automated disassembly and canning operations.

[0048] Example 3: The difference between this embodiment and the above embodiments is that this embodiment makes further structural optimizations to the shielded material discharge component 4 of the present invention. Please refer to [link to relevant documentation]. Figures 5-7 .

[0049] In this embodiment, the operating table 1 has a discharge port 11 for discharging material from the transfer tank 2. Specifically, the operating table 1 includes a base plate 13, which can be made of thick carbon steel plate to provide overall support and seismic rigidity. For example, according to the shielding requirements of the maximum residual activity of the target plate 8, the base plate 13 is a 200mm thick carbon steel plate, and the residual activity reaches the shielding requirement of 5E12Bq level, so as to provide a certain amount of additional shielding compensation during the discharge process of the transfer tank 2.

[0050] A shielding container 42 is located on one side of a base plate 13. A first shielding cover 41 is rotatably mounted on the base plate 13 at the discharge port 11, sealing the discharge port 11. The shielding container 42 is located on the outer side of the base plate 13. Specifically, the shielding container 42 can be a lead shielding container with a wall thickness of 180 mm, meeting the shielding requirement of a specific activity of 2E10 Bq / g. The shielding container 42 includes an outer container 421 and an inner container 422. The inner container 422 is located inside the outer container 421. A transfer container 2 is placed inside the inner container 422 for transfer and discharge. Specifically, after opening the first shielding cover 41, the irradiation robot grabs the transfer container 2 containing the target sheet 8 at the encapsulation assembly 3 and transfers the transfer container 2 through the discharge port 11 into the inner container 422. The shielding container 42 carries the transfer container 2 away from the exothermic chamber, and the target sheet 8 is discharged.

[0051] In a preferred embodiment, the shielding container 42 includes a second shielding cover 423, which covers the inner container 422 to seal it. A lifting structure 43 is provided on one side of the outer container 421 to drive the inner container 422 to move up and down. The lifting structure 43 penetrates the outer container 421 and lifts the inner container 422 to the discharge port 11. The first shielding cover 41 and the second shielding cover 423 are detachably connected to open the second shielding cover 423. The lifting structure 43 lifts the inner container 422 to the discharge port 11, facilitating the transfer container 2 to be transferred into the inner container 422 by the radiation-resistant robotic arm 5, thus improving operational convenience.

[0052] In some specific embodiments, a lifting structure 43 is located at the bottom of the outer tank 421. The outer tank 421 has a lifting hole, through which the lifting structure 43 passes to lift the inner tank 422. The outer diameter of the inner tank 422 is larger than the diameter of the lifting hole, preventing the inner tank 422 from detaching from the outer tank 421 through the lifting hole. When the lifting structure 43 lifts the inner tank 422 into the discharge port 11, the inner tank 422 seals the discharge port 11, maintaining the sealing and safety of the discharge channel throughout the process. Specifically, the lifting structure 43 may include a lifting cylinder, which drives the inner tank 422 to move up and down through changes in the stroke of its piston rod.

[0053] Furthermore, the first shielding cover 41 and the second shielding cover 423 can be plugged in. The first shielding cover 41 is driven by the opening drive member 47. When the first shielding cover 41 and the second shielding cover 423 are docked, the opening drive member 47 drives the first shielding cover 41 to rotate 90° relative to the base plate 13. The first shielding cover 41 can drive the second shielding cover 423 to rotate synchronously, and the first shielding cover 41 and the second shielding cover automatically complete the sealing and opening / closing operation. Specifically, the opening drive member 47 is preferably, but not limited to, a cylinder. It is understood that the detachable connection between the first shielding cover 41 and the second shielding cover 423, and the method by which the opening drive member 47 drives the first shielding cover 41 and the second shielding cover 423 to rotate as a whole, are all known to those skilled in the art and are achievable. They will not be described in detail in this embodiment.

[0054] During the discharge of the target plate 8, the lifting structure 43 first lifts the inner tank 422, which then detaches from the outer tank 421 and moves towards the discharge port 11 until the second shielding cover 423 precisely aligns with the first shielding cover 41. The opening drive 47 drives the first shielding cover 41 and the second shielding cover 423 to open simultaneously. The radiation-resistant robotic arm 5 picks up the transfer tank 2 from the encapsulation assembly 3 and places it into the inner tank 422. The opening drive 47 then drives the first shielding cover 41 and the second shielding cover 423 to close simultaneously. The lifting structure 43 drives the inner tank 422 to descend and reset, separating the second shielding cover 423 from the first shielding cover 41. The transfer tank 2 can then be transferred through the shielding tank 42 to leave the heat-exposed chamber.

[0055] In some specific embodiments, a shielding compensation structure is provided between the bottom plate 13 and the outer tank 421. The shielding compensation structure blocks or opens the discharge port 11 on the outside of the bottom plate 13. Specifically, the shielding compensation structure includes a shielding slide plate 45, which is slidably connected to the bottom plate 13. The shielding slide plate 45 is preferably, but not limited to, a lead shielding plate with a thickness of 100mm. The shielding slide plate 45 is driven by a first sliding drive member 451, which drives the shielding slide plate 45 to move laterally to block or open the discharge port 11. The shielding slide plate 45 can flexibly compensate for the local shielding loss caused by the discharge port 11. Specifically, the first sliding drive member 451 can be a cylinder.

[0056] Furthermore, a shielding cover seat 44 is provided on one side of the shielding slide plate 45. The shielding cover seat 44 is located on the top of the outer tank 421. Specifically, a sliding groove is provided at the bottom of the shielding cover seat 44. When the shielding tank 42 is conveying material, the outer tank 421 moves along the sliding groove, and the shielding cover seat 44 guides the conveying of the outer tank 421. A shielding cover is provided on the shielding cover seat 44. The shielding cover is driven by a second sliding drive component for driving the shielding cover to move. The shielding cover and the shielding slide plate 45 form a double cover structure to compensate for shielding deficiencies. The second sliding drive component can be a cylinder.

[0057] Before the lifting structure 43 drives the inner tank 422 to rise, the first sliding drive 451 drives the shielding slide plate 45 to move laterally to open the discharge port 11. The second sliding drive drives the shielding cover and shielding cover seat 44 to move in the same direction as the shielding slide plate 45. At this time, the lifting structure 43 can lift the inner tank 422 to the discharge port 11, and the second shielding cover 423 is precisely aligned with the first shielding cover 41. After the transfer tank 2 is transferred to the inner tank 422, the lifting structure 43 drives the inner tank 422 to descend, the second shielding cover 423 separates from the first shielding cover 41, the inner tank 422 leaves the discharge port 11 and enters the interior of the outer tank 421, the second sliding drive drives the shielding cover and shielding cover seat 44 to reset, and the first sliding drive 451 drives the shielding slide plate 45 to reset. The shielding slide plate 45 and the shielding cover ensure the sealing of the heat dissipation chamber and improve the shielding effect.

[0058] In some specific embodiments, the transfer roller conveyor 46 is located on the outside of the base plate 13. A lifting area is provided on the transfer roller conveyor 46, and a lifting structure 43 is located at the bottom of the transfer roller conveyor 46. Within the lifting area, the inner tank 422 is lifted. The lifting structure 43 can pass through the transfer roller conveyor 46 and the outer tank 421 to lift the inner tank 422. Before the target plate 8 is discharged, the transfer roller conveyor 46 moves and positions the shielding tank 42 to the lifting area. The lifting structure 43 lifts the inner tank 422. After the transfer tank 2 is transferred to the inner tank 422, the lifting structure 43 drives the inner tank 422 to descend and return to the interior of the outer tank 421. The transfer roller conveyor 46 can transport the shielding tank 42 to the downstream receiving end. For example, in a nuclide separation system, the transfer tank 2 and the target plate 8 enter the downstream receiving end along with the shielding tank 42.

[0059] Example 4: This embodiment, based on the above embodiments, provides a target plate feeding and discharging method. Using the aforementioned automatic feeding and discharging equipment within the heat-exothermic chamber facilitates the full automation of the target plate 8 assembly, disassembly, and discharge process. Please refer to [link to relevant documentation]. Figures 1-7 .

[0060] The target feeding and discharging method of the present invention includes the following steps: Radiation-resistant robotic arm 5 grasps the transfer container 2, and the transfer container 2 moves to the encapsulation component 3; The transfer container 2 is opened by the encapsulation assembly 3. Specifically, the radiation-resistant robot 5 places the transfer container 2 in the chuck 31, and the limiting structure 32 restricts the rotation of the cover 22. When the chuck 31 drives the container 21 to rotate relative to the cover 22, the transfer container 2 opens, the limiting structure 32 resets, and the radiation-resistant robot 5 places the cover 22 on the temporary storage seat 33. The radiation-resistant robot 5 picks up the target piece 8 and places it into the transfer container 2. Specifically, the radiation-resistant robot 5 disassembles the target piece 8 on the integrated component 62 piece by piece at the fixing frame 6, and then transfers the target piece 8 into the container 21. After all the target pieces 8 have been disassembled, the encapsulation assembly 3 closes the transfer container 2. Specifically, the radiation-resistant robot 5 closes the cover 22 on the temporary storage seat 33 onto the container 21, the limiting structure 32 repositions the cover 22, the chuck 31 drives the container 21 to rotate in the opposite direction, and the cover 22 and the container 21 are sealed together. The radiation-resistant moving component moves the transfer tank 2 to the shielding tank 42. The transfer roller conveyor 46 transports the shielding tank 42, and the target plate 8 is discharged. Specifically, the first sliding drive component 451 drives the shielding slide plate 45 to move laterally away from the discharge port 11. The second sliding drive component drives the shielding cover plate and the shielding cover plate seat 44 to move in the same direction as the shielding slide plate 45. The shielding tank 42 is conveyed to the lifting area via the transfer roller conveyor 46. The lifting structure 43 lifts the inner tank 42221 to the discharge port 11. The first shielding cover 41 and the second shielding cover 423 are precisely aligned. The opening drive component 47 drives the first shielding cover 41 and the second shielding cover 423 to flip over, and the discharge port 11 is opened. The radiation-resistant robot arm 5 grabs the transfer tank 2 and puts the transfer tank 2 into the inner tank 42221. The first shielding cover 41 and the second shielding cover 423 are closed. The lifting structure 43 drives the inner tank 42221 and the second shielding cover 423 to descend and reset. The first sliding drive 451 drives the shielding slide plate 45 to reset. The second sliding drive drives the shielding cover plate and the shielding cover plate seat 44 to reset. The transfer roller conveyor 46 conveys the shielding tank 42 and the target plate 8 is discharged.
