Step 2: The mixed two-phase liquid enters the drum, and the drum drives the rotating shaft to rotate at high speed, generating a centrifugal force field. At this time, the flow control plate in the spoiler assembly further disturbs the liquid, enhancing the mass transfer efficiency between the two phases, promoting the extraction and distribution of zirconium and hafnium between the heavy phase and the light phase. Due to the different densities of the heavy phase and the light phase, they gradually stratify under the action of centrifugal force, with the heavy phase close to the outer side of the drum and the light phase close to the inner side. Step 3: The separated light phase passes through the light phase weir plate and flows out of the centrifugal extractor through the light phase outlet; the heavy phase passes through the heavy phase weir plate and flows out through the heavy phase outlet located above the light phase outlet, thus completing a process of centrifugal extraction and separation of zirconium and hafnium.

Detailed implementation manners
[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0014] A production device for centrifugal extraction and separation of zirconium and hafnium disclosed by the present invention is mainly applied to the scenario where the existing device lacks regulation in the extraction of zirconium and hafnium, making it difficult to change the flow rate and flow direction of the liquid flow, resulting in the inability to achieve the expected mixing ratio when the heavy and light phases are mixed.
[0015] Referring to Figure 1-8 , a production device for centrifugal extraction and separation of zirconium and hafnium, comprising a centrifugal extractor 1. A mixing flow shell 12 is fixedly connected to the bottom end of the centrifugal extractor 1. A heavy-phase inlet 7 is fixedly connected to one side of the mixing flow shell 12. A light-phase inlet 8 is arranged on the side symmetrical to the heavy-phase inlet 7. The outside of the light-phase inlet 8 is fixedly connected to the outside of the mixing flow shell 12. A rotating drum 13 is arranged inside the centrifugal extractor 1. A flow disturbing component 9 is arranged inside the rotating drum 13. A shell 5 is fixedly connected to the top end of the centrifugal extractor 1. The inside of the shell 5 is movably connected to the outside of the rotating drum 13. A light-phase weir plate 17 is arranged inside the top end of the rotating drum 13. A rotating shaft 15 is arranged above the light-phase weir plate 17. A heavy-phase weir plate 16 is arranged outside the rotating shaft 15. The outside of the heavy-phase weir plate 16 is movably connected to the inside of the shell 5. A light-phase outlet 10 is fixedly connected to one side of the shell 5 close to the light-phase inlet 8. A heavy-phase outlet is arranged on the side of the shell 5 close to the heavy-phase inlet 7. The heavy-phase outlet 11 is located above the light-phase outlet 10; The flow regulating component 4 includes symmetrical arc-shaped flow disturbing plates 407, and the arc-shaped flow disturbing plates 407 are all located inside the mixing flow shell 12; The flow disturbing component 9 includes symmetrical flow control plates 904, and the flow control plates 904 are located inside the rotating drum 13.
[0016] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6, the flow regulating component 4 further includes a servo motor 401. The power output shaft of the servo motor 401 is connected with a rotating rod 402 through a coupling, and the outer side of the rotating rod 402 is movably connected to the outer side of the bottom end of the mixing housing 12. The top end of the rotating rod 402 is fixedly connected with a horizontal bevel gear 403. The outer side of the horizontal bevel gear 403 is movably connected with a vertical bevel gear 405. The vertical bevel gear 405 is meshed with the horizontal bevel gear 403 through tooth grooves. The inner side of the vertical bevel gear 405 is fixedly connected with a rotating rod 406. One end of the rotating rod 406 far from the vertical bevel gear 405 and one side of the vertical bevel gear 405 are both movably connected with retaining members 404. The opposite sides of the retaining members 404 are fixedly connected to the inner side of the mixing housing 12. The outer side of the rotating rod 406 is fixedly connected with a fixed cylinder member 412. Both inner ends of the fixed cylinder member 412 are fixedly connected with a bidirectional telescopic rod 413. The opposite ends of the two bidirectional telescopic rods 413 are both fixedly connected with movable circular members 408. Opposite sides of the movable circular members 408 are both fixedly connected with two symmetric compression springs 414. The opposite sides of the symmetric compression springs 414 are fixedly connected to both sides of the fixed cylinder member 412. The compression springs 414 are both located outside the bidirectional telescopic rods 413. Opposite sides of the movable circular members 408 are both fixedly connected with two symmetric connecting members 409. The front ends of the connecting members 409 are both movably connected with moving rods 410. The top ends of the moving rods 410 are both movably connected with connecting seats 411. The opposite ends of the connecting seats 411 are fixedly connected to the opposite sides of the arc-shaped flow disturbing plate 407.
[0017] Specifically, when mixing occurs in the mixing housing 12, the servo motor 401 is started to drive the rotating rod 402 to rotate. The horizontal bevel gear 403 at the top end of the rotating rod 402 rotates accordingly. Since the horizontal bevel gear 403 is meshed with the vertical bevel gear 405 through tooth grooves, the rotation of the horizontal bevel gear 403 will drive the vertical bevel gear 405 to rotate around its own axis. The vertical bevel gear 405 drives the fixedly connected rotating rod 406 to rotate. When the rotating rod 406 rotates, the fixed cylinder member 412 rotates accordingly. The telescopic function of the bidirectional telescopic rod 413 cooperates with the elasticity of the compression spring 414 to drive the movable circular member 408 to move inward through the centrifugal force generated by rotation, thereby adjusting the height of the arc-shaped flow disturbing plate 407 in the mixing housing 12. The arc-shaped flow disturbing plate 407 changes the flow direction and speed of the liquid, prompting the heavy phase and the light phase to be fully mixed and contacted in the mixing housing 12. During the process, the flow rate of the heavy phase and the light phase liquid during mixing can be controlled to meet the strict requirements of different processes for the feed flow rate and mixing ratio, ensuring the stability and consistency of the extraction process.
[0018] Refer to Figure 1 、 Figure 2 、 Figure 3 、and Figure 4, a base 2 is fixedly connected to the bottom end of the driving motor 6, a plurality of support frames 3 are fixedly connected to the top end of the base 2, and one side of each support frame 3 is fixedly connected to the outside of the centrifugal extractor 1. A driving motor 6 is fixedly connected to the top end of the housing 5. The power output shaft of the driving motor 6 is connected to the top end of the rotating shaft through a coupling, and a baffle 14 is fixedly connected to the bottom end of the rotating shaft. The baffle 14 is located inside the drum 13.
[0019] Referring to Figure 3 , Figure 7 and Figure 8 , the flow disturbing component 9 further includes an upper ring member 901, which is fixedly connected between the outer side of the upper ring member 901 and the inner side of the drum 13. A lower ring member 902 is arranged below the upper ring member 901. The outer side of the lower ring member 902 is movably connected to the inner side of the drum 13. Symmetric motor brackets 906 are fixedly connected to the outer side of the drum 13. Rotating motors 905 are fixedly connected to the inner sides of the motor brackets 906. The power output shafts of the rotating motors 905 are connected to rotating members 907 through couplings. Pulling ropes 908 are movably connected to the inner sides of the two rotating members 907. Limiting members 909 are movably connected to the outer sides of the pulling ropes 908. The outer sides of the limiting members 909 are fixedly connected to the outer side of the drum 13. Circular holes are formed in the upper ring member 901, and the inside of the circular holes is movably connected to the outer side of the pulling rope 908. The bottom ends of the pulling ropes 908 are fixedly connected to the top ends of the lower ring members 902. Two symmetric fixing members 913 are fixedly connected to the outer sides of the upper ring member 901 and the lower ring member 902. Rectangular holes are formed in the opposite sides of the symmetric fixing members 913. Movable plates 910 are movably connected to the inside of the rectangular holes. Support seats 911 are movably connected to the bottom ends of the movable plates 910. A round rod 912 is fixedly connected between the opposite sides of the symmetric support seats 911. The outer side of the round rod 912 is fixedly connected to the inner side of the flow control plate 904. Spring rods 903 are fixedly connected to the bottom ends of the upper ring member 901. The bottom ends of the spring rods 903 are fixedly connected to the top ends of the lower ring members 902.
[0020] Specifically, when the centrifugal force field is generated by the high-speed rotation of the rotary drum 13, the rotary motor 905 inside the motor frame 906 on the outer side of the rotary drum 13 starts to drive the rotary member 907 to rotate. When the rotary member 907 rotates, the pulling rope 908 connected movably starts to move around the rotary member 907. During the movement of the pulling rope 908, restricted by the limiting member 909, it can only move on the specified track to avoid shaking or deviation. The pulling rope 908 passes through the round hole on the upper ring member 901. As the rotary member 907 continues to rotate, the pulling rope 908 is continuously pulled, generating an upward pulling force on the lower ring member 902. The lower ring member 902 is originally movably connected to the inner side of the rotary drum 13. Under the pulling force of the pulling rope 908, it overcomes the elastic force of the spring rod 903 and moves upward, and the distance between the upper ring member 901 and the lower ring member 902 gradually decreases. Inside the symmetric fixing members 913 on the upper ring member 901 and the lower ring member 902, when the lower ring member 902 moves upward, the connected support seat 911 and the round rod 912 move synchronously, driving the flow control plate 904 to change its position and angle. The flow control plate 904 further disturbs the mixed two-phase liquid inside the rotary drum 13, enabling the liquid to have not only the movement in the centrifugal direction in the centrifugal force field, enhancing the mass transfer efficiency between the two phases, and promoting the more sufficient extraction and distribution of components such as zirconium and hafnium between the heavy phase and the light phase. When the rotary motor 905 stops working, the spring rod 903 restores its deformation, and the lower ring member 902 returns downward under the action of the spring elastic force, and the flow control plate 904 also returns to its initial position. During this process, the extractant can be fully contacted with the heavy liquid containing zirconium and hafnium, increasing the mass transfer area and accelerating the extraction reaction.
[0021] A method for using a production device for centrifugal extraction and separation of zirconium and hafnium, using a production device for centrifugal extraction and separation of zirconium and hafnium as described above, includes the following steps: Step 1: The heavy phase (heavy liquid containing components such as zirconium and hafnium) flows into the mixing shell 12 through the heavy phase inlet 7, and the light phase (light liquid such as light extractant) flows into the mixing shell 12 through the light phase inlet 8. Inside the mixing shell 12, the arc-shaped flow disturbing plate 407 in the flow regulating assembly 4 preliminarily disturbs and mixes the two-phase liquid, enabling the heavy phase and the light phase to come into preliminary contact and creating conditions for the subsequent extraction reaction. Step 2: The mixed two-phase liquid enters the rotary drum 13, and the rotary drum 13 drives the rotary shaft 15 to rotate at a high speed, generating a centrifugal force field. At this time, the flow control plate 904 in the flow disturbing assembly 9 further disturbs the liquid, enhancing the mass transfer efficiency between the two phases and promoting the extraction and distribution of zirconium and hafnium between the heavy phase and the light phase. Due to the different densities of the heavy phase and the light phase, they are gradually stratified under the action of the centrifugal force, with the heavy phase close to the outer side of the rotary drum 13 and the light phase close to the inner side. Step 3: The stratified light phase passes through the light phase weir plate 17 and flows out of the centrifugal extractor 1 through the light phase outlet 10; the heavy phase passes through the heavy phase weir plate 16 and flows out through the heavy phase outlet 11 above the light phase outlet 10, thus completing one process of centrifugal extraction and separation of zirconium and hafnium.

10. A method for using a production device for centrifugal extraction and separation of zirconium and hafnium, which uses a production device for centrifugal extraction and separation of zirconium and hafnium as described in claim 9, characterized in that, Including the following steps: Step 1: The heavy phase (heavy liquid containing components such as zirconium and hafnium) flows into the mixing shell (12) through the heavy phase inlet (7), and the light phase (light extractant liquid) flows into the mixing shell (12) through the light phase inlet (8). In the mixing shell (12), the arc-shaped flow disturbing plate (407) in the flow regulating assembly (4) preliminarily disturbs and mixes the two-phase liquid, enabling the heavy phase and the light phase to come into initial contact and creating conditions for subsequent extraction reactions; Step 2: The mixed two-phase liquid enters the rotating drum (13). The rotating drum (13) drives the rotating shaft (15) to rotate at high speed, generating a centrifugal force field. At this time, the flow control plate (904) in the flow disturbing assembly (9) further disturbs the liquid, enhancing the mass transfer efficiency between the two phases and promoting the extraction and distribution of zirconium and hafnium between the heavy phase and the light phase. Due to the different densities of the heavy phase and the light phase, they gradually separate under the action of centrifugal force. The heavy phase is close to the outer side of the rotating drum (13), and the light phase is close to the inner side; Step 3: The separated light phase passes through the light phase weir plate (17) and flows out of the centrifugal extractor (1) through the light phase outlet (10); the heavy phase passes through the heavy phase weir plate (16) and flows out through the heavy phase outlet (11) above the light phase outlet (10), thus completing a centrifugal extraction and separation process for zirconium and hafnium.
