Description

Technical Field

[0001] The embodiments of this application relate to the technical field of purifying waste gas through absorption, specifically to a tail gas treatment device and an electrolytic extraction device. Background Technology

[0002] The statements herein are provided merely as background information in connection with this application and do not necessarily constitute prior art.

[0003] Dry processing of spent fuel specifically refers to the process of processing spent fuel in a non-aqueous medium to recover actinide elements such as uranium and plutonium, and to treat radioactive waste. Its core component is the electrolytic extraction process unit, which is mainly implemented through electrolytic extraction equipment to recover transuranic elements from the molten salt after electrolytic refining.

[0004] A large amount of waste gas is generated during the electrolytic extraction process, which needs to be purified before being discharged into the external environment. Existing technologies usually use adsorption, washing and other methods to purify the exhaust gas. However, the exhaust gas treatment devices currently used in actual treatment processes still have many problems such as insufficient reaction and incomplete purification. Summary of the Invention

[0005] A brief overview of this application is provided below to offer a basic understanding of certain aspects thereof. It should be understood that this overview is not an exhaustive summary of the application. It is not intended to identify key or essential parts of the application, nor is it intended to limit its scope.

[0065] It should be noted that the accompanying drawings are not necessarily drawn to scale, but are shown only in a schematic manner without affecting the reader's understanding. Detailed Implementation

[0066] Exemplary embodiments of this application will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from the content of this application.

[0067] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the equipment structure and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0068] Because the waste gas generated during the electrolytic extraction process is radioactive, it needs to undergo strict harmless treatment until it meets emission standards before being discharged. The inventors of this application have discovered that existing exhaust gas treatment devices often have problems such as insufficient reaction between the exhaust gas and the substances used to treat the exhaust gas, resulting in incomplete purification and poor treatment effect. In order to ensure sufficient reaction between the exhaust gas and the substances used to treat the exhaust gas, methods such as extending the reaction time are generally adopted, which will affect the continuity of exhaust gas treatment and lead to problems such as reduced treatment efficiency.

[0069] Based on this, embodiments of this application provide an exhaust gas treatment device, such as... Figure 1 As shown, Figure 1A schematic diagram of the exhaust gas treatment device according to an embodiment of this application is shown. The device includes: a treatment liquid supply component 61, a first exhaust gas treatment component 62, a second exhaust gas treatment component 63, and a suction component 64. The treatment liquid supply component 61 is configured to store treatment liquid capable of purifying the exhaust gas to be treated, and is configured to supply treatment liquid to the first exhaust gas treatment component 62 and the second exhaust gas treatment component 63. The treatment liquid supply component 61 is configured to provide fluid communication between the first exhaust gas treatment component 62 and the second exhaust gas treatment component 63. The first exhaust gas treatment component 62 is configured to receive the exhaust gas to be treated. The exhaust gas is initially purified by the treatment liquid in the first exhaust gas treatment component 62. The initially purified exhaust gas enters the treatment liquid supply component 61, where it is further purified. The further purified exhaust gas enters the second exhaust gas treatment component 63, where purification is completed. The suction component 64 is configured to suction the purified exhaust gas from the second exhaust gas treatment component 63 to the external environment.

[0070] The exhaust gas treatment device provided in the embodiments of this application, by setting up a first exhaust gas treatment component 62 and a second exhaust gas treatment component 63, and using a treatment liquid supply component 61 to supply treatment liquid to both, while simultaneously making the two fluidly connected, allows the exhaust gas to be treated to react with the treatment liquid in the first exhaust gas treatment component 62, the treatment liquid supply component 61, and the second exhaust gas treatment component 63 in sequence. By adding an exhaust gas treatment step, the exhaust gas is made to have sufficient contact with the treatment liquid, ensuring that the exhaust gas is fully adsorbed by the treatment liquid; wherein, the treatment liquid supply component 61 serves to supply treatment liquid to both the first exhaust gas treatment component 62 and the second exhaust gas treatment component 63, and the connection between the two is used to... The exhaust gas supply channel also serves as a container for exhaust gas purification, simplifying the device structure as much as possible when adding an exhaust gas treatment stage. Furthermore, by setting up a suction component 64, the purified exhaust gas is drawn from the second exhaust gas treatment component 63 into the external environment, providing power for the exhaust gas to flow sequentially through the first exhaust gas treatment component 62, the treatment liquid supply component 61, and the second exhaust gas treatment component 63. Thus, the exhaust gas treatment device provided in this application can effectively enhance the exhaust gas purification effect while ensuring the continuity of the treatment process, improving purification efficiency, fully meeting the treatment needs of the large amount of exhaust gas generated by electrolysis, and avoiding the accumulation of exhaust gas that affects the normal electrolytic extraction process.

[0071] like Figure 2 As shown, Figure 2The schematic diagram of the exhaust gas treatment device from another perspective of an embodiment of this application shows that in some embodiments, the treatment liquid supply component 61 includes: a treatment liquid storage member 611, a first supply pipe 612, a second supply pipe 613, and a third supply pipe 614. The treatment liquid storage member 611 forms a cavity containing treatment liquid; the first supply pipe 612 and the second supply pipe 613 are configured to connect the cavity and the first exhaust gas treatment component 62, so that the treatment liquid is input from the cavity into the first exhaust gas treatment component 62 via the first supply pipe 612 and the second supply pipe 613; the third supply pipe 614 is configured to connect the cavity and the second exhaust gas treatment component 63, so that the treatment liquid is input from the cavity into the second exhaust gas treatment component 63 via the third supply pipe 614.

[0072] In this embodiment, the treatment liquid is introduced from the treatment liquid storage device 611 into the first exhaust gas treatment component 62 through the first liquid supply pipe 612 and the second liquid supply pipe 613, and the treatment liquid is introduced from the treatment liquid storage device 611 into the second exhaust gas treatment component 63 through the third liquid supply pipe 614, so that the exhaust gas is fully adsorbed by the treatment liquid in the first exhaust gas treatment component 62 and the second exhaust gas treatment component 63, thereby the exhaust gas is initially purified in the first exhaust gas treatment component 62 and the purification is completed in the second exhaust gas treatment component 63.

[0073] like Figure 3 As shown, Figure 3 A cross-sectional view of an exhaust gas treatment apparatus according to an embodiment of this application is shown. In some embodiments, the treatment liquid storage member 611 is formed with an exhaust gas inlet 6111 and an exhaust gas outlet 6112. The first exhaust gas treatment component 62 is in fluid communication with the treatment liquid storage member 611 via the exhaust gas inlet 6111, and the second exhaust gas treatment component 63 is in fluid communication with the treatment liquid storage member 611 via the exhaust gas outlet 6112. The exhaust gas that has undergone preliminary purification enters the treatment liquid storage member 611 from the first exhaust gas treatment component 62 via the exhaust gas inlet 6111, is purified again in the treatment liquid storage member 611, and the exhaust gas that has undergone further purification enters the second exhaust gas treatment component 63 via the exhaust gas outlet 6112.

[0074] In this embodiment, the processing liquid storage component 611 is configured to form an exhaust gas inlet 6111 and an exhaust gas outlet 6112, so that the processing liquid storage component 611 is in fluid communication with the first exhaust gas treatment component 62 and the second exhaust gas treatment component 63 respectively. This provides a flow path for the exhaust gas to flow sequentially through the first exhaust gas treatment component 62, the processing liquid storage component 611 and the second exhaust gas treatment component 63, forming a transmission path for the exhaust gas. It also serves as a container for further purification of the exhaust gas, which is beneficial for structural simplification.

[0075] like Figure 1 and Figure 2As shown, in some embodiments, the treatment fluid supply assembly 61 further includes a drain pipe 615 and an inlet pipe 616. The drain pipe 615 connects the treatment fluid storage unit 611 to an external mechanism to provide a flow channel for the treatment fluid after adsorbing the exhaust gas to be discharged from the treatment fluid storage unit 611. The inlet pipe 616 connects the treatment fluid storage unit 611 to another external mechanism to provide a flow channel for replenishing the treatment fluid in the treatment fluid storage unit 611 from the other external mechanism. This facilitates the renewal of the treatment fluid in the treatment fluid storage unit 611 during the exhaust gas treatment process.

[0076] Since chlorine gas is generated during the molten salt electrolytic extraction process, in some embodiments, an alkaline solution is used as a treatment liquid to adsorb the tail gas.

[0077] like Figure 2 and Figure 3 As shown, in some embodiments, the first exhaust gas treatment assembly 62 includes: an intake pipe 621, a first treatment body 622, a first spray pipe 623, and a second spray pipe 624. The intake pipe 621 is in fluid communication with the first treatment body 622, and the exhaust gas enters the first treatment body 622 through the intake pipe 621. The first treatment body 622 is in fluid communication with the treatment liquid supply assembly 61. The first spray pipe 623 and the second spray pipe 624 are configured to communicate with the treatment liquid supply assembly 61 and input the treatment liquid into the first treatment body 622 to spray the exhaust gas. The first spray pipe 623 is configured to spray the exhaust gas entering the first treatment body 622 preferentially compared to the second spray pipe 624.

[0078] In this embodiment, the treatment liquid is introduced into the first treatment body 622 through the first spray pipe 623 and the second spray pipe 624, so as to spray the exhaust gas input through the air inlet pipe 621 in the first treatment body 622, so that the exhaust gas and the treatment liquid can be fully contacted and thus fully adsorbed by the treatment liquid; and by setting the first spray pipe 623 and the second spray pipe 624 to spray the exhaust gas entering the first treatment body 622 in sequence, so that the exhaust gas adsorbed by the treatment liquid sprayed by the first spray pipe 623 can be adsorbed by the treatment liquid sprayed by the second spray pipe 624, thereby effectively improving the initial purification effect of the exhaust gas.

[0079] The first processing body 622 is in fluid communication with the processing liquid storage unit 611 through the exhaust gas inlet 6111, so that the exhaust gas that has been preliminarily purified in the first processing body 622 can directly enter the processing liquid storage unit 611 through the exhaust gas inlet 6111 and be purified again by the processing liquid therein.

[0080] In some embodiments, the first spray pipe 623 and the second spray pipe 624 are configured such that one end is connected to the first liquid supply pipe 612 and the second liquid supply pipe 613 respectively, and the other end extends into the first processing body 622. The processing liquid is delivered to the first spray pipe 623 and the second spray pipe 624 through the first liquid supply pipe 612 and the second liquid supply pipe 613 respectively, and sprayed out from the first spray pipe 623 and the second spray pipe 624 in the first processing body 622 to adsorb the exhaust gas entering the first processing body 622.

[0081] In some embodiments, the first processing body 622 may be configured as a cylindrical structure, with an air inlet pipe 621 disposed at the top of the cylindrical structure. The bottom of the cylindrical structure is in fluid communication with the processing liquid storage component 611 through the exhaust gas inlet 6111. The first spray pipe 623 and the second spray pipe 624 extend from different heights of the cylindrical structure through the outer wall of the cylindrical structure into its interior. The first spray pipe 623 and the second spray pipe 624 are perpendicular to each other inside the cylindrical structure, so that the processing liquid sprayed from the first spray pipe 623 and the second spray pipe 624 fully covers the exhaust gas flow path, thereby achieving full contact between the exhaust gas and the processing liquid and effectively improving the purification effect of the exhaust gas.

[0082] like Figure 2 and Figure 3 As shown, in some embodiments, the second exhaust gas treatment assembly 63 includes a second treatment body 631 and a third spray pipe 632. The third spray pipe 632 is configured to communicate with the treatment liquid supply assembly 61 and to input the treatment liquid into the second treatment body 631 to spray the exhaust gas; the second treatment body 631 has an exhaust port, and a suction assembly 64 is connected to the exhaust port to suction the exhaust gas from the second treatment body 631 to the external environment.

[0083] In this embodiment, the treatment liquid is introduced into the second treatment body 631 through the third spray pipe 632, so as to spray the exhaust gas that has been purified again by the treatment liquid storage device 611 in the second treatment body 631, so that the exhaust gas and the treatment liquid can be fully contacted and thus fully adsorbed by the treatment liquid.

[0084] The second processing body 631 is in fluid communication with the processing liquid storage unit 611 through the exhaust gas outlet 6112, so that the exhaust gas that has been purified again in the processing liquid storage unit 611 can directly enter the second processing body 631 through the exhaust gas outlet 6112 and be purified by the adsorption of the processing liquid in the second processing body 631.

[0085] In some embodiments, the third spray pipe 632 is configured such that one end is connected to the third liquid supply pipe 614 and the other end extends into the second processing body 631. The processing liquid is transported to the third spray pipe 632 through the third liquid supply pipe 614 and sprayed out from the third spray pipe 632 within the second processing body 631 to adsorb the exhaust gas entering the second processing body 631.

[0086] In some embodiments, the second processing body 631 may be configured as a cylindrical structure, with an air outlet at the top of the cylindrical structure connected to the suction assembly 64, and the bottom of the cylindrical structure in fluid communication with the processing liquid storage member 611 through the exhaust gas outlet 6112. The third spray pipe 632 extends from the outer wall of the cylindrical structure into its interior to spray the exhaust gas entering the interior of the cylindrical structure from the exhaust gas outlet 6112.

[0087] The first spray pipe 623 and the second spray pipe 624 extend into the first processing body 622 at one end, and the third spray pipe 632 extends into the second processing body 631 at one end. Multiple spray holes are formed at the end of the third spray pipe 632. The treatment liquid sprays the exhaust gas through the multiple spray holes to make the treatment liquid appear as a fine and dense water mist, which facilitates full contact with the exhaust gas and saves the amount of treatment liquid used.

[0088] like Figure 3 As shown, in some embodiments, the first exhaust gas treatment assembly 62 further includes: a first support member 625 and a second support member 626, and a plurality of porous spherical members. The first support member 625 and the second support member 626 are used to support the plurality of porous spherical members; the first support member 625 is fixedly connected to the inner side of the first treatment body 622 and is configured such that the porous spherical members it supports can cover the flow path of the treatment liquid output through the first spray pipe 623; the second support member 626 is fixedly connected to the inner side of the first treatment body 622 and is configured such that the porous spherical members it supports can cover the flow path of the treatment liquid output through the second spray pipe 624.

[0089] In this embodiment, by setting a first support member 625 and a second support member 626 to support multiple porous spherical components, the porous spherical components can respectively cover the flow path of the treatment liquid output through the first spray pipe 623 and the second spray pipe 624, so that the surface of the multiple porous spherical components is covered with treatment liquid, further ensuring that the exhaust gas entering the first treatment body 622 has sufficient contact with the treatment liquid. At the same time, by utilizing the blocking effect of the multiple porous spherical components, the flow rate of exhaust gas from the first treatment body 622 into the treatment liquid storage member 611 is slowed down, and the contact time between the exhaust gas and the treatment liquid in the first treatment body 622 is extended, thereby effectively improving the purification effect of the exhaust gas.

[0090] The first support member 625 and the second support member 626 are configured as a mesh structure to facilitate the flow of exhaust gas within the first treatment body 622. Furthermore, the mesh size is set to be smaller than the outer diameter of the porous spherical member to prevent the porous spherical member from falling off.

[0091] like Figure 3 As shown, in some embodiments, the second exhaust gas treatment assembly 63 further includes: a third support member 633 and a fourth support member 634, and a porous spherical member. The third support member 633 and the fourth support member 634 are used to support a plurality of porous spherical members; the third support member 633 is fixedly connected to the inner side of the second treatment body 631 and is configured such that the porous spherical members it supports can cover the flow path of the treatment liquid output through the third spray pipe 632; the fourth support member 634 is fixedly connected to the inner side of the second treatment body 631 and is disposed near the exhaust port of the second treatment body 631.

[0092] In this embodiment, by providing a third carrier 633 and a fourth carrier 634 that support multiple porous spherical components, the porous spherical components supported by the third carrier 633 can cover the flow path of the treatment liquid output through the third spray pipe 632, so that the surfaces of the multiple porous spherical components are covered with treatment liquid. This further ensures sufficient contact between the exhaust gas entering the second treatment body 631 and the treatment liquid, while slowing down the flow rate of the exhaust gas inside the second treatment body 631 and prolonging the contact time with the treatment liquid. Furthermore, by placing the fourth carrier 634 near the outlet of the second treatment body 631, the flow rate of the exhaust gas when it is drawn into the external environment is slowed down, further ensuring sufficient contact between the exhaust gas and the treatment liquid inside the second treatment body 631, thereby improving the purification effect of the exhaust gas.

[0093] The third support member 633 is configured as a mesh structure to facilitate the flow of exhaust gas within the second processing body 631. Furthermore, the mesh size is set to be smaller than the outer diameter of the porous spherical member to prevent the porous spherical member from falling off.

[0094] like Figure 3 As shown, in some embodiments, the suction assembly 64 includes a first air supply pipe 641, a second air supply pipe 642, and a suction member 643. The first air supply pipe 641 is configured to connect one end to the air outlet of the second processing body 631 and the other end to the suction member 643. The second air supply pipe 642 is configured to connect one end to the suction member 643 and the other end to the external environment. The suction member 643 is used to provide power for the delivery of exhaust gas, enabling the exhaust gas to be delivered from the second processing body 631 to the external environment via the first air supply pipe 641 and the second air supply pipe 642.

[0095] In this embodiment, a suction component 643 is connected to the first gas supply pipe 641 and the second gas supply pipe 642 respectively. The suction component 643 provides power so that the exhaust gas flows sequentially through the first processing body 622, the processing liquid storage component 611, and the second processing body 631. During the transmission process, the exhaust gas is purified and finally delivered to the external environment. This improves the exhaust gas treatment capacity, fully meets the processing requirements for continuous treatment of large amounts of exhaust gas generated by electrolysis, and avoids the accumulation of exhaust gas affecting the normal electrolytic extraction process. Furthermore, by placing the suction component 643 between the first gas supply pipe 641 and the second gas supply pipe 642, the exhaust gas enters the first gas supply pipe 641 from the second processing body 631 first, thus preventing the exhaust gas from being directly sucked into the suction component 643 when mixed with processing liquid, which would affect the normal operation of the suction component 643.

[0096] Under the suction action of the suction component 643, the first gas supply pipe 641 or the second gas supply pipe 642 maintains a negative pressure state and cannot be directly opened, making it inconvenient to disassemble or replace the pipeline. Based on the above problems, such as... Figure 3 As shown, in some embodiments, the exhaust gas treatment device may further include: an air supply component 644, which is disposed in the first air supply pipe 641 and is used to supply air to the first air supply pipe 641 so that its interior is in a positive pressure state when the pipe needs to be opened, so as to facilitate the disassembly and assembly of the pipe.

[0097] In some embodiments, the first gas supply pipe 641 is configured to be composed of multiple straight pipes and multiple bends connected end to end, so as to further prevent the processing liquid in the second processing body 631 from being drawn into the suction member 643 and affecting the normal operation of the suction member 643.

[0098] like Figure 4 As shown, Figure 4 for Figure 3The enlarged view shows the suction assembly and part of the first and second exhaust gas treatment assemblies. In some embodiments, the first gas supply pipe 641 may include: a first straight pipe 6411, a first bend pipe 6401, a second straight pipe 6412, a second bend pipe 6402, a third straight pipe 6413, a third bend pipe 6403, a fourth straight pipe 6414, a fourth bend pipe 6404, a fifth straight pipe 6415, a fifth bend pipe 6405, and a sixth straight pipe 6416. The first straight pipe 6411 is connected to the air outlet of the second processing body 631, and the sixth straight pipe 6416 is connected to the suction component 643. The first straight pipe 6411, the first bent pipe 6401, the second straight pipe 6412, the second bent pipe 6402, the third straight pipe 6413, the third bent pipe 6403, the fourth straight pipe 6414, the fourth bent pipe 6404, the fifth straight pipe 6415, the fifth bent pipe 6405, and the sixth straight pipe 6416 are connected end to end in sequence, so that the first air supply pipe 641 is in the shape of an "arch". By changing the exhaust gas transmission path multiple times, the treatment liquid is effectively prevented from being sucked into the suction component 643 along the direction of exhaust gas flow.

[0099] The first straight pipe 6411, the third straight pipe 6413, and the fifth straight pipe 6415 are arranged parallel to each other; the second straight pipe 6412 is arranged vertically between the first straight pipe 6411 and the third straight pipe 6413, and its two ends are connected to the first straight pipe 6411 and the third straight pipe 6413 respectively by the first bend 6401 and the second bend 6402; the fourth straight pipe 6414 is arranged vertically between the third straight pipe 6413 and the fifth straight pipe 6415, and its two ends are connected to the third straight pipe 6413 and the fifth straight pipe 6415 respectively by the third bend 6403 and the fourth bend 6404; the sixth straight pipe 6416 is arranged vertically to the fifth straight pipe 6415 and is connected to the fifth straight pipe 6415 through the fifth bend 6405, so that the first gas transmission pipe 641 is in the shape of an "arch".

[0100] In some embodiments, the first processing body 622 and the second processing body 631 are arranged parallel to each other in the vertical direction. A processing liquid storage member 611 is disposed at the bottom of the first processing body 622 and the second processing body 631, and is in fluid communication with the first processing body 622 through an exhaust gas inlet 6111 and with the second processing body 631 through an exhaust gas outlet 6112. An air inlet pipe 621 is disposed at the top of the first processing body 622, and a suction assembly 64 is disposed above the first processing body 622 and the second processing body 631, and connected to the air outlet at the top of the second processing body 631. This allows the exhaust gas to enter the first processing body 622 from the top, flow downwards through the exhaust gas inlet 6111 into the processing liquid storage member 611 at the bottom, and then rise upwards through the exhaust gas outlet 6112 into the second processing body 631, thereby changing the exhaust gas transmission path and allowing the exhaust gas to be discharged from the top of the second processing body 631 to the external environment via the suction assembly 64.

[0101] Embodiments of this application also provide an electrolytic extraction apparatus suitable for electrolyzing molten salt, with metallic cadmium as the cathode for electrolysis, such as... Figure 5 As shown, Figure 5 The diagram illustrates the structure of an electrolytic extraction apparatus according to an embodiment of this application, comprising: a tail gas treatment device 60, an electrolytic extraction generating device 20, a cathode transfer and execution device 30, a gripping device 40, and a molten salt collection assembly 50, according to any embodiment of the first aspect of this application. The tail gas treatment device 60 is used to treat the tail gas generated during electrolysis; the cathode transfer and execution device 30 is configured to transfer a cathode crucible 100 containing metallic cadmium and a cathode rod to the electrolytic extraction generating device 20, so that the generated electrolytic products remain in the cathode crucible 100, and to remove the cathode crucible 100 from the electrolytic extraction generating device 20 after electrolysis is completed; the gripping device 40 is used to transfer the anode rod to the electrolytic extraction generating device 20; the electrolytic extraction generating device 20 is configured to receive molten salt and the cathode crucible 100 from the outside, and the molten salt is electrolyzed in the electrolytic extraction generating device 20; the molten salt collection assembly 50 is used to recover the molten salt after electrolysis.

[0102] In some embodiments, the cadmium metal in the cathode crucible 100 can be solid cadmium metal. After the cathode crucible 100 is immersed in the molten salt of the electrolytic extraction generator 20 by the cathode transfer and execution device 30, the solid cadmium metal is melted into liquid cadmium metal during the heating of the molten salt.

[0103] like Figure 6 As shown, Figure 6 The diagram shows a structural schematic of an electrolytic extraction generating device according to an embodiment of this application. In some embodiments, the electrolytic extraction generating device includes: an electrolytic element 21, a heating element 22, a protective component 23, a cover component 24, and a lifting component 25. Electrolytic element 21 receives molten salt from the outside, and the molten salt is electrolyzed in electrolytic element 21; heating element 22 is configured to heat the molten salt in electrolytic element 21 to reach the temperature required for electrolysis; protection component 23 is configured to detect molten salt leakage in electrolytic element 21 and isolate the leaked molten salt from heating element 22; cover assembly 24 is configured to seal electrolytic element 21 and provide channels for anode and cathode to enter and exit electrolytic element 21, so that anode and cathode can be immersed in or removed from molten salt in electrolytic element 21 via cover assembly 24, and cover assembly 24 is configured to block the heat transfer from electrolytic element 21 to the outside; lifting component 25 is configured to apply a clamping force to cover assembly 24 to seal electrolytic element 21, or to lift cover assembly 24 to separate cover assembly 24 from electrolytic element 21.

[0104] In this embodiment, a protective component 23 is provided to detect molten salt leakage and isolate the leaking molten salt from the electrolytic element 21 from the heating element 22, so as to detect and deal with the molten salt leakage problem in a timely manner, and effectively prevent the heating element 22 from being damaged by molten salt leakage, thereby improving the safety and reliability of the molten salt electrolytic extraction process; the cover component 24 is configured to provide a channel for the anode and cathode to enter and exit the electrolytic element 21, and the cover component 24 is configured to block the heat transfer from the electrolytic element 21 to the outside, thereby improving the heat preservation performance of the electrolytic element 21 and reducing the molten salt leakage. Temperature fluctuations are prevented, and heat is avoided from being transferred from the cover assembly 24 to the electronic components of the anode and cathode, such as the conductive joints of the anode and cathode, which could cause them to fail or be damaged, thereby effectively ensuring the stability of the electrolytic reaction. Furthermore, the lifting assembly 25 is used to apply a clamping force to the cover assembly 24 as a whole or to lift it, so as to achieve the sealing of the cover assembly 24 to the electrolytic component 21 and to separate the cover assembly 24 from the electrolytic component 21. This significantly reduces the complexity of the disassembly and assembly operations between the cover assembly 24 and the electrolytic component 21 and effectively improves the efficiency of inspection and maintenance work.

[0105] In some embodiments, the cover assembly 24 is configured to insulate the electrolytic element 21 and reduce its own temperature to prevent heat transfer from the electrolytic element 21 to the outside. Since heat inside the electrolytic element 21 is easily dissipated to the external environment during electrolysis, by configuring the cover assembly 24 to insulate the electrolytic element 21 and reduce its own temperature, heat loss from the electrolytic element 21 is controlled by both reducing heat transfer to the outside and enabling self-cooling. This reduces temperature fluctuations of the molten salt inside the electrolytic element 21 during electrolytic extraction and prevents heat transfer from the cover assembly 24 to the electronic components of the anode and cathode, which could cause them to fail or be damaged.

[0106] like Figure 7 As shown, Figure 7 The diagram shows a cross-sectional view of the cover assembly 24 according to an embodiment of this application. In some embodiments, the cover assembly 24 includes: a cover 241, a cooling element 242, a heat insulation element 243, a water inlet pipe 244, and a drain pipe 245. The cover 241 is sealed to the electrolytic element 21; the heat insulation element 243 is disposed in the electrolytic element 21 and is fixedly connected to one side of the electrolytic element 21 to insulate the electrolytic element 21; the cooling element 242 is fixedly connected to the other side of the cover 241, and a cavity is formed between the cooling element 242 and the cover 241 for containing cooling water to cool the cover 241; the water inlet pipe 244 and the drain pipe 245 are in fluid communication with the cooling element 242 to refresh the cooling water in the cavity.

[0107] In this embodiment, the heat insulation element 243 and the cover element 241 are fixedly connected to one side of the electrolytic element 21 to limit the heat transfer from the electrolytic element 21 to the cover element 241. Furthermore, the cooling element 242 is fixedly connected to the other side of the cover element 241 to form a cavity for containing cooling water between the cooling element 242 and the cover element 241. The cooling water in the cavity is refreshed by the water inlet pipe 244 and the drain pipe 245 to ensure sufficient cooling of the cover element 241 and prevent the heat transferred from the electrolytic element 21 to the cover element 241 from being transferred outward.

[0108] like Figure 7 As shown, in some embodiments, the cover assembly 24 further includes an anode placement member 246. The anode placement member 246 penetrates the cavity, and its two ends are fixedly connected to the cooling member 242 and the cover member 241, respectively. The cover member 241 and the heat insulation member 243 have through holes formed at positions corresponding to the anode placement member 246, so that the anode can pass through the cavity via the anode placement member 246 and sequentially pass through the through holes formed by the cover member 241 and the heat insulation member 243 to be immersed in the molten salt of the electrolytic member 21, or removed from the molten salt.

[0109] In this embodiment, an anode placement member 246 is provided, and a cover member 241 and a heat insulation member 243 are respectively configured to form through holes at positions corresponding to the anode placement member 246, so as to provide a channel for the anode to enter and exit the electrolytic unit 21. Furthermore, by configuring the anode placement member 246 as a cavity that penetrates the cooling member 242, heat from the inside of the electrolytic unit 21 is effectively isolated from the electronic components of the anode, so as to avoid affecting the electronic components of the anode and causing the anode to fail or be damaged.

[0110] In some embodiments, the anode placement member 246 is configured as a hollow structure, and the inner diameter of the through hole formed by the cover member 241 and the heat insulation member 243 is consistent with the inner diameter of the hollow portion of the anode placement member 246, so as to form a channel for the anode to enter and exit the electrolytic member 21.

[0111] like Figure 8 As shown, Figure 8 This is a cross-sectional view showing the assembled state of the electrolytic element 21, protective component 23, cover assembly 24, and lifting assembly 25 according to an embodiment of this application. In some embodiments, the anode placement component 246 includes a placement component sealing portion 2461 and a placement component main body portion 2462. The placement component sealing portion 2461 is disposed in the cavity, with one end sealed to the cover 241, and the other end sealed to one end of the placement component main body portion 2462. The other end of the placement component main body portion 2462 is sealed to the cooling component 242 and extends away from the cover 241, such that the placement component main body portion 2462 is partially disposed outside the cavity.

[0112] In this embodiment, the anode placement member 246 is configured to include a placement member sealing part 2461 and a placement member main body part 2462. The placement member main body part 2462 forms a channel for the anode to enter and exit the electrolytic unit 21, and the placement member sealing part 2461 seals the placement member main body part 2462 and the cover member 241 to prevent cooling water in the cavity of the cooling member 242 from entering the placement member main body part 2462, thereby affecting the normal operation of the anode. Furthermore, by partially placing the placement member main body part 2462 outside the cavity, it is convenient to support the anode, while preventing the anode from contacting the outer wall of the cooling member 242, further isolating the heat inside the electrolytic unit 21 from being transferred to the electronic components of the anode.

[0113] In some embodiments, the main body 2462 of the placement member can be configured as a hollow cylindrical structure, with one end of the cylindrical structure being sealed to the placement member sealing part 2461 and the other end being sealed to the cooling member 242 and extending away from the cover member 241, so that the cylindrical structure protrudes out of the cavity, so that the anode of the rod-shaped structure can pass through the cavity via the placement member main body 2462 of the cylindrical structure, and sequentially pass through the through holes formed by the cover member 241 and the heat preservation member 243 to be immersed in the molten salt of the electrolytic member 21, or removed from the molten salt.

[0114] In some embodiments, the cover 241, the cooling element 242, and the heat insulation element 243 are all configured as annular structures, and the cover 241 and the heat insulation element 243 are configured to extend toward the center of the annular structure, so that the cover 241 and the heat insulation element 243 protrude radially out of the cooling element 242; the cover 241 cooperates with the cathode so that the cathode can be immersed in the molten salt of the electrolytic element 21 or removed from the molten salt.

[0115] In this embodiment, the cover 241, cooling element 242, and heat insulation element 243 are all arranged in annular structure to provide a channel for the cathode to enter and exit the electrolytic element 21. The cover 241 and heat insulation element 243 are arranged to protrude radially from the cooling element 242 so that when the cathode is transferred into the electrolytic element 21, the cover 241 can provide support for the cathode. Furthermore, the heat insulation effect of the heat insulation element 243 prevents the heat transferred from the inside of the electrolytic element 21 to the cover 241 from being transferred to the electronic components of the cathode.

[0116] like Figure 8As shown, in some embodiments, the electrolytic element 21 may include an electrolytic element body portion 211 and an electrolytic element mating portion 212. The electrolytic element body portion 211 is configured as a cylindrical structure with one end open. Molten salt enters the electrolytic element body portion 211 for electrolysis. The electrolytic element mating portion 212 is fixedly connected to the outer edge of the open end of the electrolytic element body portion 211. The cover 241 may include a cover first portion 2411 and a cover second portion 2412. The cover first portion 2411 and the cover second portion 2412 are integrally formed. A cavity is formed between the cover first portion 2411 and the cooling element 242. The cover first portion 2411 extends toward the center of the annular structure so as to cover part of the opening of the electrolytic element body portion 211. The cover second portion 2412 extends toward the direction away from the center of the annular structure so as to cooperate with the electrolytic element mating portion 212 to achieve a seal between the cover assembly 24 and the electrolytic element 21.

[0117] The width of the insulation member 243 can be set to be the same as the width of the first part of the cover 2411, so as to further reduce the heat transfer between the electrolytic member 21 and the first part of the cover 2411, so as to further prevent the heat inside the electrolytic member 21 from being transferred to the cathode electronic components when the cathode is transferred into the electrolytic member 21 and the first part of the cover 2411 provides support for the cathode.

[0118] like Figure 8 As shown, in some embodiments, the lifting assembly 25 includes a lifting connector 251 and a lifting actuator 252. One end of the lifting connector 251 is fixedly connected to the lifting actuator 252, and the other end is fixedly connected to the cover assembly 24. The lifting actuator 252 is configured to apply a clamping force to the cover assembly 24 by pressing the lifting connector 251, or to lift the cover assembly 24 by lifting the lifting connector 251.

[0119] In this embodiment, the lifting connector 251 is fixedly connected to the lifting actuator 252 and the cover assembly 24 so that the lifting actuator 252 can apply a clamping force to the cover assembly 24 as a whole or lift it. Thus, without complicated disassembly and assembly operations, the cover assembly 24 can seal the electrolytic element 21 and separate the cover assembly 24 from the electrolytic element 21, effectively improving the efficiency of inspection and maintenance work.

[0120] In some embodiments, one end of the lifting connector 251 is fixedly connected to the lifting actuator 252, and the other end is fixedly connected to the second part 2412 of the cover. The lifting actuator 252 presses the lifting connector 251 to apply a pressing force to the second part 2412 of the cover, thereby making the second part 2412 of the cover and the electrolytic component mating part 212 fit tightly together, which helps to ensure the sealing performance between the cover assembly 24 and the electrolytic component 21.

[0121] like Figure 9 As shown, Figure 9 This is a schematic diagram showing the structure of the cover assembly 24 and the electrolytic element 21 sealed and connected by the lifting assembly 25 according to an embodiment of the present application. In some embodiments, the lifting actuator 252 includes: a first actuator 2521, two second actuators 2522 and a third actuator 2523. The first actuator 2521 is configured as a semi-annular structure and is fixedly connected to the lifting connector 251, so that the first actuator 2521 is arranged parallel above the second part 2412 of the cover. The third actuator 2523 is used to connect to an external power mechanism to provide power for applying pressure to the lifting connector 251 or lifting it. The two second actuators 2522 are configured as a triangular structure. The first actuator 2521 is fixedly connected to one corner of the two triangular structures, and the opposite side of the corner is fixedly connected to the third actuator 2523 to provide a stable support between the third actuator 2523 and the first actuator 2521, improve the load-bearing capacity of the lifting actuator 252 and the uniformity of applying pressure to the lifting connector 251, thereby effectively enhancing the stability of the lifting actuator 252 when lifting the cover assembly 24 and enhancing the sealing performance between the cover assembly 24 and the electrolytic component 21.

[0122] like Figure 9 As shown, in some embodiments, multiple lifting connectors 251 can be provided. Multiple lifting connectors 251 are fixed to the second part 2412 of the cover at predetermined intervals and are fixedly connected to the first actuator 2521 to improve the stability of the connection between the cover assembly 24 and the lifting actuator 252, thereby further improving the load-bearing capacity of the lifting actuator 252 and the uniformity of applying the clamping force to the lifting connector 251.

[0123] like Figure 10 and Figure 11 As shown, Figure 10 The diagram shows a cross-sectional view of the electrolytic element 21, the protective component 23, and the cover component 24 in an assembly state according to an embodiment of this application. Figure 11 The diagram illustrates the structure of a leak detection element 232 according to an embodiment of this application. In some embodiments, the protection component 23 includes an isolator 231 and a leak detection element 232. The isolator 231 is disposed outside the electrolytic element 21, and the heating element 22 is disposed outside the isolator 231 so that the isolator 231 receives molten salt leaking from the electrolytic element 21. The leak detection element 232 is disposed between the electrolytic element 21 and the isolator 231, and is configured to detect molten salt leakage from the electrolytic element 21, generate a molten salt leakage signal, and transmit it outward.

[0124] In this embodiment, by placing the isolator 231 between the electrolytic element 21 and the heating element 22, the molten salt leaking from the electrolytic element 21 is isolated from the heating element 22, effectively preventing damage to the heating element 22 caused by molten salt leakage. Furthermore, by setting a leakage detection element 232 between the electrolytic element 21 and the isolator 231, the molten salt leakage situation can be monitored in real time, facilitating timely detection and handling of molten salt leakage problems. This satisfies the technical requirements for molten salt leakage monitoring and protection from two aspects: improving feedback timeliness and providing isolation protection after leakage, effectively improving the safety and reliability of the molten salt electrolytic extraction process.

[0125] like Figure 11 As shown, in some embodiments, the leakage detection element 232 includes: a signal transmission part 2321, two conductive parts 2322, and a plurality of insulating parts 2323. One end of each of the two conductive parts 2322 is connected to the signal transmission part 2321, and the other end is inserted between the electrolytic element 21 and the isolator 231, extending to contact the bottom of the isolator 231; the plurality of insulating parts 2323 are sleeved on the outside of the two conductive parts 2322 at predetermined intervals; the signal transmission part 2321 is disposed in the external environment to transmit the signal of molten salt leakage outward.

[0126] In this embodiment, the conductive part 2322 is isolated by multiple insulating parts 2323, and one end of it is connected to the signal transmission part 2321. The other end is inserted between the electrolytic element 21 and the insulating part 231 and extends to contact the bottom of the insulating part 231. By utilizing the conductive properties of molten salt, when molten salt in the electrolytic element 21 leaks between the electrolytic element 21 and the insulating part 231, the two conductive parts 2322 change from a normally open state to a normally closed state. The signal transmission part 2321 then transmits the signal change outward to monitor the molten salt leakage of the electrolytic element 21 in a timely manner, which facilitates rapid response and processing. This significantly improves the safety and reliability of the molten salt electrolytic extraction process.

[0127] In some embodiments, the conductive part 2322 can be two tungsten wires, and the insulating part 2323 can be a ceramic tube, with multiple ceramic tubes sleeved around the two tungsten wires at predetermined intervals. When molten salt leaks between the electrolytic element 21 and the isolator 231, the two tungsten wires change from a normally open state to a normally closed state. This switching signal is converted into a passive switching signal by an intermediate relay and transmitted to an external PLC system via the signal transmission part 2321 for alarm purposes.

[0128] like Figure 12 As shown, Figure 12The diagram shows a schematic of the cathode transfer and execution device according to an embodiment of the present application assembled in an electrolytic extraction device. In some embodiments, the cathode transfer and execution device includes: a connecting assembly 31, a sealing member 32, a cathode rod assembly 33, a crucible support assembly 34, a reciprocating stirring assembly 35, and a rotary stirring assembly 36. The connecting assembly 31 is configured to support and drive the cathode rod assembly 33, crucible support assembly 34, reciprocating stirring assembly 35, and rotary stirring assembly 36 into and out of the electrolytic extraction generating device 20; the sealing member 32 is configured to cooperate with the electrolytic extraction generating device 20, so that the cathode rod assembly 33, crucible support assembly 34, reciprocating stirring assembly 35, and rotary stirring assembly 36 are partially sealed in the electrolytic extraction generating device 20; the cathode rod assembly 33 is used to conduct electricity to the molten salt; the crucible support assembly 34 is configured to support the cathode crucible 100, so that the cathode crucible 100 is immersed in or removed from the molten salt; the reciprocating stirring assembly 35 is used to reciprocate and stir the liquid cadmium metal in the cathode crucible 100; the rotary stirring assembly 36 is used to rotary and stir the molten salt.

[0129] In this embodiment, the cathode rod assembly 33, crucible support assembly 34, reciprocating stirring assembly 35, and rotary stirring assembly 36 are transferred together to the electrolytic extraction generator 20 via the connecting assembly 31, thereby simplifying the cathode transfer process and improving transfer efficiency. Furthermore, by configuring the sealing member 32 to cooperate with the electrolytic extraction generator 20, when the connecting assembly 31 carries the cathode rod assembly 33, crucible support assembly 34, reciprocating stirring assembly 35, and rotary stirring assembly 36 into the electrolytic extraction generator 20, the components are partially sealed within the electrolytic extraction generator 20. This optimizes the sealing performance of the electrolytic extraction generator 20 after the cathode is transferred to it, facilitating the occurrence of the electrolytic reaction.

[0130] Furthermore, the cathode rod assembly 33, crucible support assembly 34, reciprocating stirring assembly 35, and rotary stirring assembly 36 are transferred together to the electrolytic extraction generator 20 via the connecting assembly 31. This allows the cathode rod assembly 33 to conduct electricity into the molten salt, and the cathode crucible 100 containing metallic cadmium, supported by the crucible support assembly 34, to be immersed in the molten salt for electrolysis. The reciprocating stirring assembly 35 also allows the liquid metallic cadmium in the cathode crucible 100 to be reciprocated and stirred. During the molten salt electrolysis process, the electrolytic products generated between the liquid metallic cadmium and the molten salt are... The material is pressed down into the cathode crucible 100, so that the electrolysis products remain in the cathode crucible 100, which facilitates the collection and transfer of the electrolysis products. At the same time, it can reduce the surface tension between liquid cadmium metal and molten salt, increase the contact area between liquid cadmium metal and molten salt, and prevent the electrolysis products from hindering the contact and reaction between the two, which is conducive to promoting the reaction process and improving the electrolysis efficiency. Furthermore, the rotary stirring component 36 can rotate and stir the molten salt to promote the flow of molten salt, so that the molten salt can fully react with the liquid cadmium metal, thereby ensuring the uniformity and quality of the obtained electrolysis products.

[0131] In some embodiments, the cathode rod assembly 33, the crucible support assembly 34, the reciprocating stirring assembly 35, and the rotary stirring assembly 36 are fixed to the connecting assembly 31 and extend from one side of the seal 32 through the seal 32 to the other side, and are sealed to the seal 32. When the seal 32 is engaged with the electrolytic extraction generating device 20, the cathode rod assembly 33, the crucible support assembly 34, the reciprocating stirring assembly 35, and the rotary stirring assembly 36 are partially sealed in the electrolytic extraction generating device 20. This allows the cathode rod assembly 33, crucible support assembly 34, reciprocating stirring assembly 35, and rotary stirring assembly 36 to be transferred into the electrolytic extraction generator 20 via the displacement of the connecting component 31. Furthermore, the cooperation between the sealing element 32 and the electrolytic extraction generator 20 partially seals the cathode rod assembly 33, crucible support assembly 34, reciprocating stirring assembly 35, and rotary stirring assembly 36 within the electrolytic extraction generator 20. This simplifies the cathode transfer process while optimizing the sealing performance of the electrolytic extraction generator 20 after the cathode is transferred, ensuring the stability of the electrolysis process.

[0132] The sealing element 32 is arranged parallel to the connecting assembly 31 in the vertical direction so that the cathode rod assembly 33, the crucible support assembly 34, the reciprocating stirring assembly 35 and the rotating stirring assembly 36 are fixed to the connecting assembly 31, and can extend from one side of the sealing element 32 through the sealing element 32 to the other side.

[0133] like Figure 13 As shown, Figure 13The diagram shows a schematic of the cathode transfer and execution device according to an embodiment of this application. In some embodiments, the connecting component 31 includes a support member 311, a reinforcing member 312, and a sliding connector 313. The cathode rod assembly 33, the crucible support assembly 34, the reciprocating stirring assembly 35, and the rotary stirring assembly 36 are fixedly connected to the support member 311. The sliding connector 313 is slidably connected to an external mechanism and fixedly connected to the support member 311, so that the support member 311 is moved by the sliding connector 313, thereby driving the cathode rod assembly 33, the crucible support assembly 34, the reciprocating stirring assembly 35, and the rotary stirring assembly 36 to enter and exit the electrolytic extraction generator 20. The reinforcing member 312 is fixedly connected to the support member 311 and the sliding connector 313 to improve the connection strength between the support member 311 and the sliding connector 313.

[0134] In this embodiment, the cathode rod assembly 33, crucible support assembly 34, reciprocating stirring assembly 35, and rotary stirring assembly 36 are fixedly connected to the carrier 311 so that the carrier 311 can be moved by the displacement of the sliding connector 313, thereby transferring the cathode rod assembly 33, crucible support assembly 34, reciprocating stirring assembly 35, and rotary stirring assembly 36 together to or from the electrolytic extraction generating device 20; and the connection between the carrier 311 and the sliding connector 313 is strengthened by the reinforcement 312, which helps to enhance the stability during the cathode transfer process.

[0135] In some embodiments, the sliding connector 313 and the carrier 311 are arranged to be perpendicular to each other. The reinforcing member 312 can be provided in two forms and is arranged in a right-angled triangular structure. One right-angled side of the two right-angled triangular structures is fixedly connected to the carrier 311, and the other right-angled side is fixedly connected to the sliding connector 313, so as to effectively enhance the connection strength between the carrier 311 and the sliding connector 313.

[0136] like Figure 13 and Figure 14 As shown, Figure 14This diagram illustrates the assembly state of the cathode rod assembly 33 according to an embodiment of the present application. In some embodiments, the cathode rod assembly 33 includes: a cathode rod drive member 331, a cathode rod fixing member 332, a first telescopic member 333, and a cathode rod 334. The cathode rod drive member 331 is fixedly connected to the support member 311, and the cathode rod fixing member 332 is slidably connected to the cathode rod drive member 331. The cathode rod 334 passes through the cathode rod fixing member 332, the support member 311, and the sealing member 32, and is fixedly connected to the cathode rod fixing member 332. The cathode rod drive member 331 drives the cathode rod 334 to move along its axial direction by driving the cathode rod fixing member 332. The first telescopic member 333 is sleeved on the cathode rod 334, and one end of the first telescopic member 333 is fixedly connected to the support member 311, and the other end is sealed to the sealing member 32. The first telescopic member 333 is configured to compress when the sealing member 32 cooperates with the electrolytic extraction generating device 20.

[0137] In this embodiment, the cathode rod 334 is fixed to the cathode rod fixing member 332, and passes through the cathode rod fixing member 332, the carrier member 311, and the sealing member 32 in sequence. The first telescopic member 333 is sleeved on the cathode rod 334, with one end fixedly connected to the carrier member 311 and the other end sealed to the sealing member 32. When the cathode is transferred to the electrolytic extraction generating device 20, the sealing member 32 cooperates with the electrolytic extraction generating device 20 to compress and shorten the first telescopic member 333. At this time, the cathode rod 334 can still move along the cathode rod 334. Its axial movement reaches a predetermined position, thereby enabling the cathode rod 334 to move axially even when partially sealed inside the electrolytic extraction generating device 20. Furthermore, by configuring the cathode rod drive member 331 to drive the cathode rod 334 to move axially by driving the cathode rod fixing member 332, it is convenient to control the axial movement of the cathode rod 334 to immerse it in or remove it from the molten salt when the cathode rod 334 is partially sealed inside the electrolytic extraction generating device 20, thereby facilitating the control of the molten salt electrolysis process.

[0138] like Figure 13 As shown, in some embodiments, the crucible support assembly 34 includes a crucible lifting member 341, a second telescopic member 342, and a crucible support member 343. The crucible lifting member 341 is fixedly connected to the bearing member 311 and passes through the sealing member 32. The crucible support member 343 is used to support the cathode crucible 100 and is fixedly connected to the crucible lifting member 341. The second telescopic member 342 is sleeved on the crucible lifting member 341, and one end of the second telescopic member 342 is fixedly connected to the bearing member 311, and the other end is sealed to the sealing member 32. The second telescopic member 342 is configured to compress when the sealing member 32 cooperates with the electrolytic extraction generating device 20.

[0139] In this embodiment, the crucible lifting member 341 is fixedly connected to the carrier member 311 and fixedly connected to the crucible support member 343 through the sealing member 32. The second telescopic member 342 is sleeved on the crucible lifting member 341, with one end fixedly connected to the carrier member 311 and the other end sealed to the sealing member 32. When the cathode is transferred to the electrolytic extraction generating device 20, the sealing member 32 cooperates with the electrolytic extraction generating device 20 to compress and shorten the second telescopic member 342. At this time, the crucible lifting member 341 can still move along its axial direction so that the crucible support member 343 carrying the cathode crucible 100 can move to a predetermined position. Thus, the crucible lifting member 341 can still drive the crucible support member 343 to move along its axial direction even when partially sealed inside the electrolytic extraction generating device 20.

[0140] In some embodiments, two crucible lifting members 341 may be provided. One end of the two crucible lifting members 341 is fixed to the bearing member 311, and the other end is fixedly connected to the outer edge of the crucible support member 343. They are arranged symmetrically about the center of the crucible support member 343 to improve the bearing capacity of the crucible support member 343 and enhance the stability of the cathode crucible 100 transfer.

[0141] like Figure 15 and Figure 16 As shown, Figure 15 This diagram shows a structural schematic of a crucible support 343 supporting a cathode crucible 100 according to an embodiment of this application. Figure 16 This diagram illustrates a crucible support 343 supporting a cathode crucible 100 according to an embodiment of the present application. In some embodiments, the crucible support 343 includes a supporting portion 3431, a limiting portion 3432, and a blocking portion 3433. The supporting portion 3431 supports the cathode crucible 100 and is fixedly connected to the crucible lifting member 341. The limiting portion 3432 and the blocking portion 3433 protrude from the supporting portion 3431, with the limiting portion 3432 positioned relative to the blocking portion 3433 near the outer edge of the supporting portion 3431. The limiting portion 3432 limits the cathode crucible 100, and the blocking portion 3433 prevents the cathode crucible 100 from directly contacting the supporting portion 3431.

[0142] In this embodiment, a limiting part 3432 and a blocking part 3433 are provided on the supporting part 3431 for supporting the cathode crucible 100. The limiting part 3432 is positioned closer to the outer edge of the supporting part 3431 than the blocking part 3433. When the cathode crucible 100 is transferred to the supporting part 3431, the limiting part 3432 restricts the cathode crucible 100 to a predetermined position on the supporting part 3431. The blocking part 3433 prevents the cathode crucible 100 from directly contacting the supporting part 3431, avoiding the generation of electrolysis products that cause the cathode crucible 100 to stick to the supporting part 3431, thus facilitating the separation of the cathode crucible 100 from the supporting part 3431.

[0143] like Figure 15 As shown, multiple blocking portions 3433 and multiple limiting portions 3432 are provided. The multiple blocking portions 3433 are arranged at predetermined distances, and each blocking portion 3433 is equidistant from the center of the supporting portion 3431. The multiple limiting portions 3432 are arranged at predetermined distances, and each limiting portion 3432 is equidistant from the center of the supporting portion 3431. The distance between each limiting portion 3432 and the center of the supporting portion 3431 is set to be greater than the distance between each blocking portion 3433 and the center of the supporting portion 3431. Furthermore, the protrusion height of the blocking portion 3433 on the supporting portion 3431 is less than the protrusion height of the limiting portion 3432 on the supporting portion 3431, so that when the cathode crucible 100 is transferred to the supporting portion 3431, the bottom of the cathode crucible 100 is separated from the supporting portion 3431 by the blocking portion 3433, and the cathode crucible 100 is restricted to a predetermined position on the supporting portion 3431 by the limiting portion 3432.

[0144] like Figure 16 As shown, in some embodiments, the support portion 3431 is configured as a non-closed annular structure so that the crucible support 343 can be automatically connected to the cathode crucible 100 and transferred to the electrolytic extraction generator 20, and after electrolysis is completed, the cathode crucible 100 can be automatically separated from the crucible support 343.

[0145] like Figure 17 As shown, Figure 17This diagram illustrates the assembly state of the sealing member 32 with a portion of the cathode rod assembly 33, the crucible support assembly 34, the reciprocating stirring assembly 35, and the rotary stirring assembly 36 according to an embodiment of this application. In some embodiments, the crucible lifting member 341 further includes a first lifting portion 3411, a crucible lifting limiting portion 3412, and a second lifting portion 3413. The first lifting portion 3411 is fixedly connected to the bearing member 311 and passes through the sealing member 32. The second lifting portion 3413 is fixedly connected to the crucible support member 343. The crucible lifting limiting portion 3412 is used to connect the first lifting portion 3411 and the second lifting portion 3413, and to limit the displacement of the crucible support member 343 relative to the sealing member 32 when the cathode crucible 100 is lifted, thereby facilitating the automatic connection and automatic separation of the cathode crucible 100 and the crucible support member 343.

[0146] The crucible lifting limiting part 3412 is configured as a right-angle structure. The first lifting part 3411 and the second lifting part 3413 are respectively fixedly connected to the two ends of the right-angle structure so as to prevent the crucible support 343 from moving toward the sealing member 32 when the cathode crucible 100 is lifted, thereby achieving the effect of limiting the relative position between the crucible support 343 and the sealing member 32.

[0147] like Figure 13 and Figure 18 As shown, Figure 18 The diagram shows a structural schematic of a reciprocating stirring assembly 35 according to an embodiment of the present application. In some embodiments, the reciprocating stirring assembly 35 includes: a reciprocating stirring member drive 351, a reciprocating stirring member fixing member 352, a third telescopic member 353, and a reciprocating stirring member 354. The reciprocating stirring drive 351 is fixedly connected to the bearing 311; the reciprocating stirring fixing 352 is slidably connected to the reciprocating stirring drive 351; the reciprocating stirring 354 passes through the sealing member 32 and is fixedly connected to the reciprocating stirring fixing 352. The reciprocating stirring drive 351 drives the reciprocating stirring 354 to reciprocate along its axial direction by driving the reciprocating stirring fixing 352, so that the reciprocating stirring 354 reciprocates to stir the liquid cadmium metal in the cathode crucible 100; the third telescopic member 353 is sleeved on the reciprocating stirring 354, and one end of the third telescopic member 353 is fixedly connected to the reciprocating stirring fixing 352, and the other end is sealed to the sealing member 32 and passes through the sealing member 32. The third telescopic member 353 is configured to compress when the sealing member 32 cooperates with the electrolytic extraction generating device 20.

[0148] In this embodiment, the reciprocating stirring member 354 is fixedly connected to the reciprocating stirring member fixing member 352, and the third telescopic member 353 is sleeved on the reciprocating stirring member 354, with one end fixedly connected to the reciprocating stirring member fixing member 352 and the other end sealed and connected to the sealing member 32 and passing through the sealing member 32. When the cathode is transferred to the electrolytic extraction generating device 20, the sealing member 32 cooperates with the electrolytic extraction generating device 20, causing the third telescopic member 353 to compress and shorten. At this time, the reciprocating stirring member 354 can still move along its axial direction to the predetermined position. Thus, the reciprocating stirring member 354 can still move along its axial direction under the condition of being partially sealed inside the electrolytic extraction generating device 20. Furthermore, by reciprocating... The stirring element fixing member 352 is slidably connected to the reciprocating stirring element driving member 351. When the reciprocating stirring element 354 is partially sealed inside the electrolytic extraction generating device 20, the reciprocating stirring element driving member 351 drives the reciprocating stirring element fixing member 352 to drive the reciprocating stirring element 354 to reciprocate along its axial direction, thereby realizing the reciprocating stirring of the liquid cadmium metal in the cathode crucible 100. This facilitates the pressing of the electrolytic products generated between the liquid cadmium metal and the molten salt into the cathode crucible 100, so as to facilitate the collection and transfer of the electrolytic products. At the same time, it reduces the surface tension between the liquid cadmium metal and the molten salt, increases the contact area between the liquid cadmium metal and the molten salt, and avoids the electrolytic products from hindering the contact and reaction between the two.

[0149] like Figure 17 As shown, in some embodiments, the reciprocating stirrer 354 includes a stirring connection part 3541 and a stirring execution part 3542. One end of the stirring connection part 3541 is fixedly connected to the reciprocating stirrer fixing part 352, and the other end is fixedly connected to the stirring execution part 3542. The stirring execution part 3542 is configured as a plate-shaped structure that can enter and exit the cathode crucible 100. By controlling the reciprocating stirrer drive part 351 to drive the reciprocating stirrer fixing part 352 to drive the stirring connection part 3541 to reciprocate along its axial direction, the stirring execution part 3542 is driven to reciprocate the liquid cadmium metal in the cathode crucible 100.

[0150] The plate-shaped stirring actuator 3542 has multiple through holes to reduce the surface tension between the liquid cadmium metal and the molten salt and increase the contact area between them while pressing the electrolytic products generated between the liquid cadmium metal and the molten salt into the cathode crucible 100.

[0151] In some embodiments, two stirring connection parts 3541 may be provided, and the two stirring connection parts 3541 are symmetrically connected to one side of the stirring execution part 3542 with the center of the stirring execution part 3542 as the axis, so as to avoid the stirring execution part 3542 tilting and ensure the stability of its reciprocating motion.

[0152] like Figure 18As shown, in some embodiments, the reciprocating stirring member fixing member 352 may include a fixing member first part 3521, a fixing member second part 3522, and a fixing member extension 3523. The fixing member first part 3521, the fixing member second part 3522, and the fixing member extension 3523 are integrally formed. The fixing member extension 3523 is disposed between the fixing member first part 3521 and the fixing member second part 3522. Two stirring connection parts 3541 are fixedly connected to the fixing member first part 3521 and the fixing member second part 3522, respectively.

[0153] like Figure 19 As shown, Figure 19 The diagram shows a cross-sectional view of the sealing member 32, the third telescopic member 353, and the rotary stirring assembly 36 along a radial section of the third telescopic member 353 according to an embodiment of this application. In some embodiments, the third telescopic member 353 includes a first telescopic portion 3531, a second telescopic portion 3532, and a blocking portion 3533. The first telescopic portion 3531, the second telescopic portion 3532, and the blocking portion 3533 are integrally formed. The first telescopic portion 3531 is disposed at one end of the second telescopic portion 3532, and the blocking portion 3533 is disposed at the other end of the second telescopic portion 3532. The first telescopic portion 3531 is configured to be fixedly connected to the reciprocating stirring member fixing member 352 and to be sealed to the sealing member 32. The second telescopic portion 3532 is configured to penetrate the sealing member 32. The blocking portion 3533 is fixedly connected to the reciprocating stirring member 354 and is configured to limit the reciprocating stirring member 354 when it reciprocates along its axial direction.

[0154] In this embodiment, the first telescopic part 3531 is fixedly connected to the reciprocating stirring member fixing member 352 and sealed with the sealing member 32. When the cathode is transferred to the electrolytic extraction generating device 20, the sealing member 32 cooperates with the electrolytic extraction generating device 20 to compress and shorten the first telescopic part 3531. At this time, the reciprocating stirring member 354 can still move to the predetermined position along its axial direction. Furthermore, by disposing the second telescopic part 3532 between the first telescopic part 3531 and the blocking part 3533 and penetrating through the sealing member 32, the blocking part 3533 is configured to limit the reciprocating stirring member 354 when it reciprocates along its axial direction, so as to limit the displacement range of the reciprocating stirring member 354 along its axial direction.

[0155] Specifically, when the reciprocating agitator 354 moves along its axial direction toward the reciprocating agitator fixing member 352, the second telescopic part 3532 is compressed and shortened, and the blocking part 3533 moves toward the reciprocating agitator fixing member 352 until the blocking part 3533 contacts the sealing member 32, so as to restrict the reciprocating agitator 354 from continuing to move toward the reciprocating agitator fixing member 352; when the reciprocating agitator 354 moves along its axial direction away from the reciprocating agitator fixing member 352, the second telescopic part 3532 extends back to its original position.

[0156] like Figure 13 and Figure 19 As shown, in some embodiments, the rotary stirring assembly 36 includes: a rotary stirring element drive 361, a rotary stirring element 362, and a sealing connector 363. The rotary stirring element drive 361 is fixedly connected to the support member 311; the rotary stirring element 362 is fixedly connected to the rotary stirring element drive 361 and passes through the sealing member 32. The rotary stirring element drive 361 drives the rotary stirring element 362 to rotate, thereby stirring the molten salt; the sealing connector 363 is configured to seal the rotary stirring element 362 to the sealing member 32.

[0157] In this embodiment, the rotating stirring element 362 is fixedly connected to the rotating stirring element drive 361 and passes through the sealing element 32. The sealing connection 363 is configured to seal the rotating stirring element 362 and the sealing element 32, so that the rotating stirring element drive 361 drives the rotating stirring element 362 to rotate and stir the molten salt while ensuring the sealing performance, thereby promoting the flow of molten salt and enabling the molten salt to fully react with liquid cadmium metal.

[0158] In some embodiments, the rotary agitator 362 is configured such that its position for rotary agitation of the molten salt is slightly higher than the range for reciprocating agitation of the molten salt by the reciprocating agitator 354, in order to avoid mutual interference between rotary agitation and reciprocating agitation.

[0159] like Figure 17 As shown, in some embodiments, the rotary stirring member 362 includes a stirring rod 3621 and a stirring paddle 3622. One end of the stirring rod 3621 is connected to the rotary stirring member drive member 361, and the other end passes through the sealing member 32 and is connected to the stirring paddle 3622, so that the rotary stirring member drive member can drive the stirring rod 3621 to rotate, thereby driving the stirring paddle 3622 to rotate and stir the molten salt.

[0160] like Figure 20 and Figure 21 As shown, Figure 20 This diagram shows a structural schematic of the carrier 311 according to an embodiment of this application. Figure 21The diagram shows a schematic of the cathode rod assembly 33, crucible support assembly 34, reciprocating stirring assembly 35, and rotary stirring assembly 36 assembled on a carrier 311 according to an embodiment of this application. In some embodiments, the carrier 311 includes a first mounting part 3111, a second mounting part 3112, a third mounting part 3113, a fourth mounting part 3114, a fifth mounting part 3115, and a sixth mounting part 3116. The cathode rod assembly 33 is fixedly connected to the first mounting part 3111 and the second mounting part 3112, the crucible support assembly 34 is fixedly connected to the third mounting part 3113 and the fourth mounting part 3114, the reciprocating stirring assembly 35 is fixedly connected to the fifth mounting part 3115, and the rotary stirring assembly 36 is fixedly connected to the sixth mounting part 3116; the third mounting part 3113 is disposed between the first mounting part 3111 and the second mounting part 3112, and the third mounting part 3113 and the fourth mounting part 3114 are symmetrically disposed on both sides of the sixth mounting part 3116, and the fifth mounting part 3115 is disposed on the side of the fourth mounting part 3114 away from the sixth mounting part 3116.

[0161] In this embodiment, the carrier 311 is divided into multiple mounting parts, and the cathode rod assembly 33, crucible support assembly 34, reciprocating stirring assembly 35 and rotary stirring assembly 36 are fixed in different mounting parts to avoid mutual interference when the components are working. At the same time, the installation space of the carrier 311 is effectively utilized through reasonable layout to ensure that the device structure is compact.

[0162] like Figure 20 and Figure 21 As shown, the crucible lifting members 341 of the two outer sleeves of the crucible support assembly 34 are fixedly connected to the third mounting part 3113 and the fourth mounting part 3114, respectively. The cathode rod driving member 331 of the cathode rod assembly 33 is fixedly connected to the first mounting part 3111. The cathode rod fixing member 332 is parallel to the support member 311 and has no contact. The cathode rod 334 is fixed to the cathode rod fixing member 332 and passes through the second mounting part 3112. The first telescopic member 333 is fixedly connected to the second mounting part 3112 to install the cathode rod assembly 33 on the support member 311, while providing installation space for one of the crucible lifting members 341.

[0163] Furthermore, the reciprocating stirring component drive 351 of the reciprocating stirring assembly 35 is fixedly disposed on the fifth mounting part 3115, and the reciprocating stirring component fixing component 352 can be configured as a "V" shaped structure, parallel to the support component 311 without contact. Its fixing component first part 3521 and fixing component second part 3522 extend to both sides of the sixth mounting part 3116, so that the stirring connection part 3541 of the two outer sleeve third telescopic component 353 connected to the fixing component first part 3521 and fixing component second part 3522 extends from both sides of the sixth mounting part 3116 toward the sealing component 32, so as to install the reciprocating stirring assembly 35 on the support component 311, while providing installation space for another crucible lifting component 341 and the rotary stirring assembly 36, so as to achieve full and effective utilization of the installation space of the support component 311.

[0164] The rotary stirring component drive 361 of the rotary stirring assembly 36 is fixed to the sixth mounting part 3116, and the rotary stirring component 362 extends through the sixth mounting part 3116 and toward the sealing component 32, so as to mount the rotary stirring assembly 36 onto the support component 311.

[0165] like Figure 22 As shown, Figure 22 The diagram illustrates the structure of a gripping device according to an embodiment of this application. In some embodiments, the gripping device includes: a plurality of actuators 41, a first direction transmission assembly 42, a plurality of second direction transmission assemblies 43, a power member 44, and a support connection assembly 45. The plurality of actuators 41 are configured to simultaneously apply clamping forces to objects of different diameters to grip the objects. The first direction transmission assembly 42 is configured to drive the plurality of second direction transmission assemblies 43 to simultaneously move closer to or away from the first direction transmission assembly 42 through its own rotation. The plurality of second direction transmission assemblies 43 are configured to drive the plurality of actuators 41 to simultaneously move closer to or away from the first direction transmission assembly 42, so that the plurality of actuators 41 simultaneously apply clamping forces to objects of different diameters. The power member 44 is configured to drive the first direction transmission assembly 42 to rotate. The support connection assembly 45 is configured to provide support for the power member 44 and fix the first direction transmission assembly 42 and the plurality of second direction transmission assemblies 43. The support connection assembly 45 is used to connect to an external mechanism. The first direction and the second direction are perpendicular to each other.

[0166] In this embodiment, a first direction transmission component 42 and a second direction transmission component 43 with mutually perpendicular transmission directions are provided. The first direction transmission component 42 is configured to drive multiple second direction transmission components 43 to simultaneously move closer to or away from the first direction transmission component 42 through its own rotation, thereby converting the rotational motion of the first direction transmission component 42 in the first direction into the displacement of the second direction transmission component 43 in the second direction. Furthermore, multiple second direction transmission components 43 drive multiple actuators 41 to simultaneously move closer to or away from the first direction transmission component 42, so as to quickly adjust the distance between the second direction transmission components 43 and the first direction transmission component 42 according to the diameter of the object to be grasped. Then, the second direction transmission components 43 drive multiple actuators 41 to simultaneously apply clamping force to objects of different diameters. Thus, the grasping device can quickly adjust the grasping size to be suitable for grasping objects of different sizes, avoiding process interruptions caused by adjusting the grasping size, effectively ensuring the tight connection between processes, and improving the continuity of the electrolytic extraction process.

[0167] like Figure 23 As shown, Figure 23 The diagram shows a cross-sectional view of the gripping device according to an embodiment of this application along a first direction. In some embodiments, the support connection assembly 45 includes: a connector 451, a power component support 452, and a first fixing member 453. The connector 451 is used to connect to an external mechanism; the power component support 452 is supported between the connector 451 and the first fixing member 453, forming a receiving space, and the power component 44 is disposed within the receiving space and connected to the first direction transmission assembly 42; the first fixing member 453 is connected to the first direction transmission assembly 42 and a plurality of second direction transmission assemblies 43 respectively to fix the first direction transmission assembly 42 and the plurality of second direction transmission assemblies 43.

[0168] In this embodiment, a power component support 452 is provided between the connector 451 and the first fixing member 453 to provide a space for the power component 44, so that the power component 44 can be fixed between the connector 451 and the first fixing member 453, so that the power component 44 can be connected to the first directional transmission assembly 42 and drive the first directional transmission assembly 42 to rotate; and the first fixing member 453 is used to fix the first directional transmission assembly 42 and a plurality of second directional transmission assemblies 43 respectively to ensure the stability of the first directional transmission assembly 42 and the plurality of second directional transmission assemblies 43 when rotating or displacing.

[0169] In some embodiments, the connector 451 is connected to an external actuator, such as a robotic arm, for moving the gripping device as a whole.

[0170] like Figure 24 As shown, Figure 24The diagram shows an exploded view of the gripping device according to an embodiment of this application. In some embodiments, the power component support 452 includes a plurality of rods 4521 and at least one plate 4522. The plurality of rods 4521 are vertically connected to the outer edge of the plate 4522, so that the plate 4522 is snapped between the plurality of rods 4521. The connecting member 451 has through holes equal in number to the plurality of rods 4521. One end of the plurality of rods 4521 is inserted into the through holes, and the other end is fixedly connected to the first fixing member 453 to form a receiving space for mounting the power component 44. The power component 44 is fixed to the plate 4522 and passes through the plate 4522 to connect to the first direction transmission assembly 42.

[0171] like Figure 23 As shown, in some embodiments, the first direction transmission assembly 42 includes: a second fixing member 421, a rotating member 422, and a reciprocating member 423. The second fixing member 421 is used to fix the rotating member 422 and is configured to connect the power member 44 and the rotating member 422, so that the power member 44 can drive the rotating member 422 to rotate; the rotating member 422 is configured to drive the reciprocating member 423 to move along its first direction by its own rotation, and the reciprocating member 423 is configured to drive multiple second direction transmission assemblies 43 to simultaneously approach or move away from the rotating member 422, so that the multiple second direction transmission assemblies 43 drive multiple actuators 41 to simultaneously approach or move away from the rotating member 422.

[0172] In this embodiment, the rotating component 422 is fixed by the second fixing component 421 and connected to the power component 44 so that the rotating component 422 can rotate along its own axis and drive the reciprocating motion component 423 to move along its first direction. The reciprocating motion component 423 drives multiple second direction transmission components 43 to move closer to or further away from the rotating component 422 at the same time, so as to change the distance between the second direction transmission components 43 and the rotating component 422, thereby quickly adjusting the gripping size to be suitable for gripping objects of different sizes.

[0173] In some embodiments, the second fixing member 421 is fixedly connected to the power member support member 452, and the second fixing member 421 has a through hole, through which the rotating member 422 passes and is fixed, so that the power member 44 and the rotating member 422 are connected; the rotating member 422 is threadedly connected to the first fixing member 453; the reciprocating member 423 is threadedly connected to the rotating member 422, and the reciprocating member 423 is fixedly connected to a plurality of second direction transmission components 43. The rotating member 422 rotates to drive the reciprocating member 423 to reciprocate along its first direction, and the reciprocating member 423 drives the plurality of second direction transmission components 43 to reciprocate along the first direction of the rotating member 422.

[0174] In this embodiment, the second fixing member 421 is fixedly connected to the power component support member 452, and the rotating member 422 is passed through and fixed to the second fixing member 421. This ensures the stability of the connection between the rotating member 422 and the power component 44, while limiting the displacement of the rotating member 422 in the first direction to ensure the stability of the transmission from the rotating member 422 to the reciprocating motion member 423. This avoids the inability to accurately adjust the gripping size due to the rotating member 422 shifting its axis, thus affecting the stability of the gripping. Furthermore, the rotating member 422 is threadedly connected to the first fixing member 453. This ensures that the rotating component 422 can rotate along its own axis while further restricting the displacement of the rotating component 422 in the first direction. By threading the reciprocating motion component 423 to the rotating component 422, the rotation of the rotating component 422 along its own axis is converted into the displacement of the reciprocating motion component 423 in the first direction. This allows the reciprocating motion component 423 to drive multiple second direction transmission components 43 to reciprocate along the first direction of the rotating component 422, thereby changing the distance between the second direction transmission components 43 and the rotating component 422 and realizing the adjustment of the gripping size.

[0175] In some embodiments, the second fixing member 421 is a plate-shaped structure, which is arranged parallel to at least one plate 4522 of the power member support member 452, and a plurality of rods 4521 are vertically connected to the outer edge of the second fixing member 421, so that the second fixing member 421 is engaged between the plurality of rods 4521, thereby ensuring the stability of the connection between the second fixing member 421 and the power member support member 452, thereby effectively ensuring the stable connection between the rotating member 422 and the power member 44, while limiting the displacement of the rotating member 422 in the first direction.

[0176] In some embodiments, the rotating member 422 has an external thread, and the reciprocating member 423 has an internal thread that matches the external thread, so that the rotating member 422 rotates to drive the reciprocating member 423 to reciprocate along its first direction. The engagement between the external thread of the rotating member 422 and the internal thread of the reciprocating member 423 improves the conversion efficiency of the rotational motion of the rotating member 422 into the reciprocating motion of the reciprocating member 423 along the first direction. This allows for rapid adjustment of the distance between the second-direction transmission assembly 43 and the rotating member 422, and also enables precise control of the position of the reciprocating member 423 on the rotating member 422, achieving rapid and precise adjustment of the gripping size. This is suitable for meeting the technical requirements of gripping objects of different sizes in a short time.

[0177] like Figure 24As shown, in some embodiments, the reciprocating motion component 423 includes a first connecting portion 4231, a second connecting portion 4232, and an opening portion 4233. The first connecting portion 4231, the second connecting portion 4232, and the opening portion 4233 are integrally formed. The first connecting portion 4231 and the second connecting portion 4232 are arranged perpendicularly to each other in a "+" shape. The opening portion 4233 is formed at the intersection of the two. The opening portion 4233 has a through hole, and an internal thread matching the external thread of the rotating component 422 is formed on the inner side of the through hole. The rotating component 422 passes through the through hole to achieve a threaded connection with the reciprocating motion component 423. A plurality of second direction transmission components 43 are fixedly connected to the two ends of the first connecting portion 4231 and the second connecting portion 4232, so that the plurality of second direction transmission components 43 can simultaneously approach or move away from the rotating component 422 from different directions.

[0178] like Figure 23 As shown, in some embodiments, the second directional transmission assembly 43 includes: a transmission member 431, a first connector 432, a second connector 433, and a third connector 434. The first connector 432 is configured such that one end is fixed to the support connection assembly 45, and the other end is rotatably connected to one end of the second connector 433 and the third connector 434. The other ends of the second connector 433 and the third connector 434 are fixedly connected to the actuator 41. The transmission member 431 is configured to drive the second connector 433 to move closer to or away from the first directional transmission assembly 42, causing the second connector 433 to drive the third connector 434 to rotate around the first connector 432, thereby driving the actuator 41 to move closer to or away from the first directional transmission assembly 42.

[0179] In this embodiment, one end of the first connector 432 is fixed to the support connection assembly 45, and the other end is rotatably connected to one end of the second connector 433 and the third connector 434. The transmission member 431 is configured to drive the second connector 433 to move closer to or further away from the first direction transmission assembly 42, so that the second connector 433 and the third connector 434 can rotate with the support connection assembly 45 as the fulcrum through the connection between the first connector 432 and the support connection assembly 45, thereby quickly adjusting the distance between them and the first direction transmission assembly 42 under the action of the transmission member 431.

[0180] In some embodiments, one end of the first connecting member 432 is fixedly connected to the first fixing member 453, one end of the transmission member 431 is fixedly connected to the reciprocating motion member 423, and the other end is fixedly connected to the second connecting member 433. By fixing one end of the first connecting member 432 to the first fixing member 453, the second connecting member 433 and the third connecting member 434 can rotate around the first fixing member 453 as a fulcrum. By fixing one end of the transmission member 431 to the reciprocating motion member 423 and the other end to the second connecting member 433, the displacement of the reciprocating motion member 423 in the first direction is converted into the displacement of the second connecting member 433 and the third connecting member 434 in the second direction. This allows the second connecting member 433 and the third connecting member 434 to quickly adjust the distance between themselves and the first direction transmission assembly 42.

[0181] like Figure 24 As shown, in some embodiments, the actuator 41 includes a recess 411, a first pressing portion 412, and a second pressing portion 413. The recess 411 is formed between the first pressing portion 412 and the second pressing portion 413 to apply a pressing force to objects of different diameters. Since objects of different diameters have different surface areas available for gripping, by designing the actuator 41 as described above, the first pressing portion 412 can be selected to apply a pressing force to the object according to the gripping requirements of objects of different diameters, or the first pressing portion 412 and the second pressing portion 413 can be selected to apply a pressing force to the object together, thereby ensuring the stability of the grip. Furthermore, by providing the recess 411 between the first pressing portion 412 and the second pressing portion 413, compared to the actuator 41 applying a pressing force to the object as a whole, the pressure on the object surface can be reduced, ensuring non-destructive gripping.

[0182] For example, when gripping small-diameter workpieces, such as anode rods, since the surface area available for gripping is small, only the first clamping part 412 can be used to apply clamping force to ensure a stable grip. When gripping large-diameter workpieces, such as cathode crucibles, the surface area available for gripping is large, so the first clamping part 412 and the second clamping part 413 can be used together to apply clamping force to the object. At the same time, the recess 411 avoids excessive pressure on the surface of the cathode crucible, so as to achieve non-destructive gripping while ensuring a stable grip.

[0183] The first pressing part 412 and the second pressing part 413 are formed with transverse textures to enhance the friction between the first pressing part 412 and the second pressing part 413 and the object, effectively ensuring the stability of the actuator 41 when gripping objects of different diameters.

[0184] like Figure 23 and Figure 24As shown, in some embodiments, the first connector 432 includes a first fixing portion 4321, a second fixing portion 4322, and an extension portion 4323. The first fixing portion 4321, the second fixing portion 4322, and the extension portion 4323 are integrally formed. The first fixing portion 4321 is fixedly connected to the support connecting assembly 45, and the second fixing portion 4322 is rotatably connected to the second connector 433 and the third connector 434. The first fixing portion 4321 is located at one end of the extension portion 4323, and the second fixing portion 4322 is located at the other end of the extension portion 4323, so that the second connector 433 and the third connector 434 can rotate around the support connecting assembly 45 as a fulcrum, thereby moving closer to or away from the first direction transmission assembly 42.

[0185] like Figure 24 As shown, in some embodiments, the first fixing part 4321 is formed with a first fixing end 43211 and a second fixing end 43212. The first fixing end 43211 and the second fixing end 43212 extend outward parallel from the extension part 4323, and there is a gap between the first fixing end 43211 and the second fixing end 43212. The gap cooperates with the support connection component 45, and the first fixing end 43211 and the second fixing end 43212 are configured to be fixedly connected to the support connection component 45 to ensure that the first fixing part 4321 is firmly connected to the support connection component 45. This improves the stability of the connection between the first connector 432 and the support connection component 45, and ensures the flexibility and stability of the second connector 433 and the third connector 434 rotating with the support connection component 45 as the fulcrum.

[0186] like Figure 24 As shown, in some embodiments, the first fixing member 453 has a through hole 4531, and the inner side of the through hole 4531 has a thread that mates with the rotating member 422. The rotating member 422 passes through the through hole 4531 and is threadedly connected to the first fixing member 453. The outer edge of the first fixing member 453 also has a plurality of grooves 4532 for mates with the gap of the first fixing part 4321 of the first connector 432, so that the first connector 432 is inserted into the first fixing member 453, thereby increasing the contact area between the first connector 432 and the first fixing member 453, and further improving the stability and reliability of the connection between the first connector 432 and the first fixing member 453.

[0187] like Figure 5 As shown, Figure 5The diagram illustrates the structure of an electrolytic extraction apparatus according to an embodiment of this application. In some embodiments, the electrolytic extraction apparatus may further include: a body 10. The body 10 forms a receiving space, and the electrolytic extraction generating device 20 is disposed within the receiving space and communicates with the outside of the receiving space; a cathode transfer and execution device 30 is slidably connected to the body 10; a molten salt collection assembly 50 is disposed within the receiving space; and a tail gas treatment device 60 is disposed outside the receiving space.

[0188] In this embodiment, the electrolytic extraction generating device 20 for providing the molten salt electrolysis environment is placed within the accommodating space formed by the main body 10 and communicated with its exterior. The cathode transfer and execution device 30 is slidably connected to the main body 10, so as to facilitate the transfer of the cathode crucible 100 and the cathode rod 334 to the electrolytic extraction generating device 20. This improves the automation level of the cathode transfer, which is beneficial to improving the automation level of the molten salt electrolytic extraction process, optimizing the continuity of the overall electrolytic extraction process, and enhancing the safety and convenience of the equipment in a high-radioactive environment.

[0189] like Figure 5 As shown, in some embodiments, the body 10 may include: an electrolytic transfer support assembly 11, a crucible support assembly 12, and a cathode transfer support assembly 13. The crucible support assembly 12 is configured to temporarily store the cathode crucible 100 to be transferred; the electrolytic transfer support assembly 11 is configured to be arranged parallel to the crucible support assembly 12 in a first direction, forming a first receiving space 111, and the electrolytic extraction generating device 20 is disposed in the first receiving space 111 and communicates with the outside of the first receiving space 111; the cathode transfer support assembly 13 is configured to be arranged parallel to the crucible support assembly 12 and the electrolytic transfer support assembly 11 in a second direction, and the cathode transfer and execution device 30 is slidably connected to the cathode transfer support assembly 13; the cathode transfer support assembly 13 forms a second receiving space 131, and the molten salt collecting assembly 50 is disposed in the second receiving space 131; the first direction and the second direction are perpendicular to each other.

[0190] In this embodiment, the electrolytic transfer support assembly 11 is arranged parallel to the crucible support assembly 12 in the first direction, and the cathode transfer support assembly 13 is arranged parallel to the crucible support assembly 12 and the electrolytic transfer support assembly 11 in the second direction. The electrolytic extraction generating device 20 is placed in the first accommodating space 111 formed by the electrolytic transfer support assembly 11 and communicates with its exterior. The cathode transfer and execution device 30 is slidably connected to the cathode transfer support assembly 13, so that the cathode transfer and execution device 30 can transfer the cathode crucible 100 temporarily stored in the crucible support assembly 12 to the electrolytic extraction generating device 20 along the first direction, or transfer the cathode crucible 100 out of the electrolytic extraction generating device 20 after electrolysis is completed, thereby shortening the transfer distance of the cathode crucible 100 and improving the continuity of the cathode transfer process. In addition, the molten salt collection assembly 50 is placed in the second accommodating space 131 formed by the cathode transfer support assembly 13 to effectively improve space utilization and achieve a compact layout.

[0191] In some embodiments, the first direction and the second direction are perpendicular to each other in the horizontal direction. The electrolytic transfer support assembly 11, the crucible support assembly 12, and the cathode transfer support assembly 13 form a double-layer space in the vertical direction. The first accommodating space 111 formed by the electrolytic transfer support assembly 11 and the second accommodating space 131 formed by the cathode transfer support assembly 13 are located in the first layer space. The electrolytic extraction generating device 20 is disposed in the first layer space and extends into the second layer space. The cathode transfer and execution device 30 is slidably connected to the cathode transfer support assembly 13 in the second layer space. The molten salt collection assembly 50 is disposed in the first layer space, so that the cathode transfer is carried out in the second layer space and the molten salt recovery is carried out in the first layer space. This allows different functional areas to be divided into different layers of space, resulting in a reasonable and compact layout that facilitates the improvement of the overall process continuity.

[0192] like Figure 25 As shown, Figure 25 The diagram shows a partial structural schematic of the electrolytic extraction device according to another perspective of an embodiment of the present application. In some embodiments, the electrolytic element 21, the heating element 22 and the protection component 23 of the electrolytic extraction generating device 20 are disposed in the first accommodating space 111, and the electrolytic element 21 and the protection component 23 are in communication with the outside of the first accommodating space 111. The lifting component 25 is slidably connected to the electrolytic transfer support component 11.

[0193] In this embodiment, the electrolytic element 21, the heating element 22, and the protection component 23 are disposed in the first accommodating space 111, and the electrolytic element 21 and the protection component 23 are connected to the outside of the first accommodating space 111 to receive the cathode transferred by the cathode transfer and the actuator 30, and to enable the protection component 23 to transmit the detected molten salt leakage signal of the electrolytic element 21 to the outside of the first accommodating space 111; the lifting component 25 is slidably connected to the electrolytic transfer support component 11 to provide power for the lifting component 25, so that the lifting component 25 can apply a clamping force to the cover component 24 or lift the cover component 24.

[0194] like Figure 5 and Figure 25 As shown, in some embodiments, the electrolytic transfer support assembly 11 includes: a first mounting member 112, a plurality of first rods 113, a cover transfer member 114, and a second mounting member 115. One end of each first rod 113 is fixedly connected to one side of the first mounting member 112, and the other end is fixedly connected to the second mounting member 115 to form a first receiving space 111; the first mounting member 112 has a through hole, the protective assembly 23 is detachably connected to the through hole, the electrolytic element 21 is disposed in the protective assembly 23 and extends from the through hole to the outside of the first receiving space 111; the cover transfer member 114 is disposed on the other side of the first mounting member 112, the cover transfer member 114 is slidably connected to the lifting assembly 25, and is configured to drive the lifting assembly 25 to lift or rotate.

[0195] In this embodiment, a first receiving space 111 is formed by one side of the first mounting member 112, multiple first rods 113, and the second mounting member 115. The electrolytic element 21 extends from the through hole formed by the first mounting member 112 to the outside of the first receiving space 111. The cover transfer member 114 is disposed on the other side of the first mounting member 112, so that the cover transfer member 114 is slidably connected to the lifting assembly 25 outside the first receiving space 111. This facilitates the application of a clamping force to the cover assembly 24, so that the cover assembly 24 seals the electrolytic element 21, or lifts the cover assembly 24 and drives the cover assembly 24 to rotate, thereby providing space for disassembly and maintenance of the electrolytic element 21 and the protection assembly 23.

[0196] Specifically, when the electrolytic element 21 or the protection component 23 needs to be replaced or repaired, the lifting component 25 is raised and rotated by the cover transfer component 114 to lift the cover component 24 so that it is separated from the electrolytic element 21 and rotated to a position not on the replacement path of the electrolytic element 21 and the protection component 23. Then, the electrolytic element 21 and the protection component 23 are moved out of the first receiving space 111 in sequence through the through hole formed by the first mounting component 112 so as to replace or repair the electrolytic element 21 or the protection component 23.

[0197] Since the electrolytic element 21 of the electrolytic extraction generating device 20 extends from the through hole to the outside of the first receiving space 111, and there is no fixed connection between it and the first mounting member 112, it is fixed only by the connection between the protective component 23 and the first mounting member 112. Therefore, in some embodiments, the electrolytic extraction generating device 20 may also include a support member 26. The support member 26 is fixedly connected to the outer edge of the opening end of the electrolytic element 21, so that one end of the support member 26 is supported on one side of the cover transfer member 114 of the first mounting member 112, so as to support the electrolytic element 21 on the first mounting member 112 and ensure the stability of the electrolytic element 21. Furthermore, multiple support members 26 may be provided, and multiple support members 26 are equidistantly arranged on the outer edge of the opening end of the electrolytic element 21 to ensure that the opening end of the electrolytic element 21 remains parallel to the first mounting member 112, thereby further improving the stability of the electrolytic element 21 and facilitating the cooperation with the cathode transfer and execution device 30.

[0198] like Figure 5 and Figure 26 As shown, Figure 26 The diagram showing the electrolytic extraction generating device 20 and the electrolytic transfer support assembly 11 according to an embodiment of this application omits the first mounting member 112, the first rod 113, the second mounting member 115, the third mounting member 116, and the fourth mounting member 117. In some embodiments, the electrolytic transfer support assembly 11 further includes: the third mounting member 116, the fourth mounting member 117, the heating element transfer guide 118, the heating element support 119, the heating element transfer drive 1101, and the positioning member 1102. The third mounting member 116 is disposed between the second mounting member 115 and the fourth mounting member 117, and is fixedly connected to the second mounting member 115 and the fourth mounting member 117; the heating element transfer guide 118 is disposed between the second mounting member 115 and the third mounting member 116; the heating element support 119 is used to support the heating element 22 and is slidably connected to the heating element transfer guide 118; one end of the heating element transfer drive 1101 is disposed on the fourth mounting member 117, and the other end is disposed on the heating element support 119, so as to drive the heating element support 119 to slide along the heating element transfer guide 118; the positioning member 1102 is disposed at the end of the heating element transfer guide 118 away from the third mounting member 116, so as to block the heating element support 119 into position.

[0199] In this embodiment, the heating element transfer guide 118 is disposed on the second mounting member 115 and the third mounting member 116, and the heating element support 119 is slidably connected to the heating element transfer guide 118. Simultaneously, the heating element transfer drive 1101 drives the heating element support 119 to slide along the heating element transfer guide 118. When the heating element 22 needs to be replaced or repaired, the heating element transfer drive 1101 drives the heating element support 119 to move out of the first receiving space 111 along the heating element transfer guide 118, thereby moving the heating element 22. Remove the heating element 22 from the first receiving space 111; after the heating element 22 has been repaired or replaced, place the heating element 22 on the heating element support 119 and use the heating element transfer drive 1101 to drive the heating element support 119 to enter the first receiving space 111 along the heating element transfer guide 118; the positioning element 1102 is used to prevent the heating element support 119 from continuing to slide along the heating element transfer guide 118 after the heating element support 119 carries the heating element 22 to a predetermined position in the first receiving space 111, so as to limit the displacement of the heating element 22.

[0200] In some embodiments, the heating element transfer guide 118 may be configured as a slide rail, and the heating element support 119 may be configured as a tray structure that can cooperate with the slide rail, so that the tray structure can carry the heating element 22 to slide along the slide rail, thereby facilitating the heating element 22 to enter or be moved out of the first receiving space 111.

[0201] like Figure 26 and Figure 27 As shown, Figure 27 The diagram illustrates the structure of the electrolytic extraction generator 20 and the molten salt collection assembly 50 according to embodiments of this application. In some embodiments, the molten salt collection assembly 50 includes a molten salt collection element 51, a protective element 52, and a suction power element 53. The protective element 52 is disposed between the molten salt collection element 51 and the suction power element 53, and is connected to both via pipelines. The molten salt collection element 51 is connected to the electrolytic element 21 of the electrolytic extraction generator 20 via a pipeline. The suction power element 53 provides power for the output of molten salt from the electrolytic element 21, so that after electrolysis is completed, the molten salt is automatically output from the electrolytic element 21 to the molten salt collection element 51 using the suction power element 53, thereby improving the automation level of molten salt recovery. The protective element 52 is used to prevent molten salt from being sucked into the suction power element 53 and affecting its normal operation.

[0202] In some embodiments, the cathode transfer and execution device 30 is configured to automatically connect to and automatically separate from the cathode crucible 100, so as to transfer the cathode crucible 100 to the electrolytic extraction generator 20 using the cathode transfer and execution device 30, and to separate the cathode crucible 100 containing electrolytic products from the cathode transfer and execution device 30 and transfer it to the next process, thereby improving the automation level of cathode transfer and electrolytic product transfer and improving the continuity of the process.

[0203] like Figure 25 As shown, in some embodiments, the crucible support assembly 12 includes: a fifth mounting member 121, a plurality of second rods 122, a support frame 123, a crucible storage member 124, and a crucible receiving member 125. One end of each second rod 122 is fixedly connected to one side of the fifth mounting member 121, and the other end is fixedly connected to the support frame 123; the crucible storage member 124 and the crucible receiving member 125 are disposed on the other side of the fifth mounting member 121. The crucible storage member 124 is configured to confine the cathode crucible 100 within the fifth mounting member 121 to temporarily store the cathode crucible 100 to be transferred. The crucible receiving member 125 is configured to make the cathode crucible 100 protrude from the fifth mounting member 121, so that the cathode transfer and actuation device 30 can automatically connect to and automatically separate from the cathode crucible 100.

[0204] In this embodiment, a crucible storage component 124 is provided in the fifth mounting component 121 to provide space for temporarily storing the cathode crucible 100. This facilitates the timely replacement of the cathode crucible 100 with a new one after the previous cathode crucible 100 is recovered, thereby ensuring the continuity of the process and improving electrolysis efficiency. A crucible receiving component 125 is provided to facilitate the cooperation between the cathode crucible 100 and the cathode transfer and execution device 30.

[0205] In some embodiments, the fifth mounting member 121 may be configured to be on the same horizontal plane as the first mounting member 112, and the crucible storage member 124 and the crucible receiving member 125 may be disposed in the second layer space to facilitate the cooperation between the cathode transfer and execution device 30 and the crucible storage member 124 and the crucible receiving member 125, thereby improving the continuity of the process.

[0206] In some embodiments, the gripping device 40 can be used to transfer the cathode crucible 100 to be transferred from the crucible storage container 124 to the crucible receiving container 125, so that the cathode transfer and execution device 30 is automatically connected to the cathode crucible 100. After the electrolysis is completed, after the crucible receiving container 125 and the cathode crucible 100 are automatically separated, the gripping device 40 can be used to transfer the cathode crucible 100 remaining in the crucible receiving container 125 to the next process.

[0207] like Figure 25As shown, in some embodiments, the crucible receiving member 125 includes a support portion 1251 and a supporting portion 1252. The support portion 1251 is used to support the cathode crucible 100. One end of the supporting portion 1252 is fixedly connected to the fifth mounting member 121, and the other end is fixedly connected to the support portion 1251, so that the support portion 1251 protrudes from the fifth mounting member 121. This facilitates the cooperation between the cathode transfer and execution device 30 and the cathode crucible 100, enabling automatic connection and automatic separation from the cathode crucible 100.

[0208] like Figure 25 As shown, in some embodiments, the connecting component 31 of the cathode transfer and execution device 30 is slidably connected to the cathode transfer support component 13, so as to provide power for the automatic connection and automatic separation between the cathode crucible 100 and the cathode transfer and execution device 30, and to provide power for the cathode transfer to and from the electrolytic extraction generator 20.

[0209] In some embodiments, the crucible support assembly 34 is configured to cooperate with the support portion 1251 and automatically connect and disconnect from the cathode crucible 100. When the cathode crucible 100 to be transferred needs to be transferred to the electrolytic extraction generator 20, the cooperation between the crucible support assembly 34 and the support portion 1251 automatically connects the cathode crucible 100 to the crucible support assembly 34. Then, the cathode transfer support assembly 13 provides power to the connecting assembly 31, causing the connecting assembly 31 to drive the crucible support assembly 34 carrying the cathode crucible 100 to transfer to the electrolytic extraction generator 20. During electrolysis... When the cathode crucible 100 containing electrolytic products needs to be recovered after the process is completed, the cathode transfer support assembly 13 provides power to the connecting assembly 31, causing the connecting assembly 31 to drive the crucible support assembly 34 carrying the cathode crucible 100 out of the electrolytic extraction generator 20. Then, through the cooperation between the crucible support assembly 34 and the support part 1251, the cathode crucible 100 containing electrolytic products is automatically separated from the crucible support assembly 34 and remains in the support part 1251. This facilitates the recovery of the cathode crucible 100 containing electrolytic products and further improves the automation level of cathode transfer and electrolytic product recovery.

[0210] In some embodiments, the support portion 1251 may be configured as a disc-shaped structure, with the outer diameter of the disc-shaped structure being smaller than the inner diameter of the bearing portion 3431 of the annular structure of the crucible support member 343 in the crucible support assembly 34. The support portion 1252 may be configured as a rod-shaped structure, supporting the support portion 1251 so that the support portion 1251 protrudes from the fifth mounting member 121 to cooperate with the bearing portion 3431 of the crucible support member 343 in the crucible support assembly 34, which is configured as a non-closed annular structure. When it is necessary to transfer the cathode crucible 100 to the electrolytic extraction generating device 20, the cathode crucible 100 is transferred from the crucible temporary storage member 124 to the support portion 1251 of the crucible receiving member 125. Under the action of the cathode transfer support assembly 13, the connecting assembly 31 drives the crucible support assembly 34 to descend, causing the support portion 1252 to move from the crucible support member 343. The unclosed portion of the support part 3431 extends into the center of the support part 3431. At this time, under the action of the cathode transfer support assembly 13, the connecting assembly 31 drives the crucible support assembly 34 to rise, so that the cathode crucible 100 on the support part 1251 remains on the support part 3431, thereby realizing the automatic connection between the crucible support assembly 34 and the cathode crucible 100. After the electrolysis is completed, when it is necessary to recover the cathode crucible 100 containing the electrolysis products, under the action of the cathode transfer support assembly 13, the connecting assembly 31 drives the crucible support assembly 34 carrying the cathode crucible 100 to transfer out of the electrolysis extraction generator 20. When the center of the support part 3431 and the center of the support part 1251 are on the same straight line in the vertical direction, it descends, so that the cathode crucible 100 containing the electrolysis products remains on the support part 1251, thereby realizing the automatic separation between the crucible support assembly 34 and the cathode crucible 100.

[0211] like Figure 25 As shown, in some embodiments, the cathode transfer support assembly 13 includes: a sixth mounting member 132, a plurality of third rods 133, a seventh mounting member 134, a first-direction cathode transfer member 135, and a third-direction cathode transfer member 136. The third direction is perpendicular to both the first and second directions. One end of each third rod 133 is fixedly connected to one side of the sixth mounting member 132, and the other end is fixedly connected to the seventh mounting member 134 to form a second receiving space 131. The first-direction cathode transfer member 135 is disposed on the other side of the sixth mounting member 132 and is slidably connected to the third-direction cathode transfer member 136 to drive the third-direction cathode transfer member 136 to move in the first direction. The third-direction cathode transfer member 136 is slidably connected to the connecting assembly 31 to drive the connecting assembly 31 to move in the third direction upward.

[0212] In this embodiment, a first-direction cathode transfer component 135 and a third-direction cathode transfer component 136 are provided on the sixth mounting component 132, and the first-direction cathode transfer component 135 and the third-direction cathode transfer component 136 are slidably connected, so that the cathode transfer and execution device 30 can move upward in the first direction and the third direction, thereby facilitating cathode transfer and electrolysis product recovery operations.

[0213] In some embodiments, the third direction is perpendicular to the first and second directions in the vertical direction to achieve the raising or lowering of the cathode transfer and actuation device 30.

[0214] The process of extracting transuranium elements from molten salt using electrolytic extraction equipment is further explained below.

[0215] Solid cadmium metal is placed into multiple cathode crucibles to obtain multiple cathode crucibles 100 containing solid cadmium metal. These cathode crucibles 100 are then placed in the crucible storage component 124 of the crucible support assembly 12 of the main body 10 for transfer. The electrolytic element 21 is heated using the heating element 22 of the electrolytic extraction generator 20. During heating, molten salt is fed into the electrolytic element 21 using a transfer pump, and the electrolytic element 21 is continuously heated at 450°C until the molten salt melts. The anode rod 200 is inserted into the electrolytic element 21 from the anode placement component 246 of the cover assembly 24 of the electrolytic extraction generator 20 using a gripping device 40, immersing the anode rod 200 in the molten salt. Finally, the cathode crucibles 100 on the crucible storage component 124 are transferred to the crucible receiving component using the gripping device 40. The cathode transfer and execution device 30 moves in a third direction using the cathode transfer support assembly 13 of the main body 10. The crucible support member 343 of the crucible support assembly 34 of the cathode transfer and execution device 30 cooperates with the crucible receiving member 125, so that the cathode crucible 100 is automatically connected to the crucible support member 343. Then, the cathode transfer support assembly 13 of the main body 10 drives the cathode transfer and execution device 30 to move in the first direction, so as to transfer the cathode rod 334 and the cathode crucible 100 containing solid cadmium metal into the electrolytic extraction generating device 20 through the channel formed by the cover assembly 24 of the electrolytic extraction generating device 20, and immerse the cathode crucible 100 containing solid cadmium metal into the molten salt, and pass through the electrolytic extraction generating device 20. The fit between the cover 241 of the cover assembly 24 and the sealing element 32 of the cathode transfer and execution device 30 partially seals the cathode transfer and execution device 30 within the electrolytic extraction generator 20. The molten salt is held at 450°C for a predetermined time, causing the solid cadmium metal in the cathode crucible 100 to melt into liquid cadmium metal. The cathode rod drive 331 drives the cathode rod fixing element 332 to move the cathode rod 334 axially, immersing it in the molten salt. The anode rod 200 and cathode rod 334 are connected to an external power source, maintaining the electrolysis temperature at 450°C to electrolytically extract transuranic elements from the molten salt. During the electrolysis of the molten salt, the rotating stirring assembly 36 of the cathode transfer and execution device 30 is used to stir the molten salt. The liquid cadmium metal is stirred by rotating and stirring, and the electrolytic product is deposited in the cathode crucible 100 to form a transuranic cadmium alloy product. After electrolysis is completed, the cathode transfer support assembly 13 drives the cathode transfer and execution device 30 to be transferred out of the electrolytic extraction generator 20. The cathode crucible 100 is left on the crucible receiving device 125 by the cooperation between the crucible support 343 of the crucible support assembly 34 of the cathode transfer and execution device 30 and the crucible receiving device 125, so that the cathode crucible 100 is automatically separated from the crucible support 343. After the cathode crucible 100 is left to stand for a predetermined time, the cathode crucible 100 is put into a sealed container by the gripping device 40 and transferred as a whole to the next process.The gripping device 40 then transfers a new cathode crucible 100 containing solid cadmium metal from the crucible storage unit 124 to the crucible receiving unit 125 to replace the new cathode crucible 100 for electrolysis, obtaining multiple cathode crucibles 100 containing electrolysis products. These multiple cathode crucibles 100 are then subjected to vacuum distillation to separate the electrolysis products from the cadmium metal and molten salt, allowing for the extraction of transuranic elements from the electrolysis products. After the molten salt electrolysis in the electrolysis unit 21 is completed, a vacuum negative pressure suction method is used, utilizing the suction power component 53 of the molten salt collection assembly 50, to transfer the molten salt from the electrolysis extraction generator 20 to the molten salt collection unit 51. During the electrolysis process, the exhaust gas generated is continuously transferred to the exhaust gas treatment device 60 for spray adsorption treatment until it meets the standards before being discharged.
