Description

Technical Field

[0001] The present invention relates to the technical field of separation and purification, and in particular to a zirconium and hafnium separation and extraction device and an extraction method. Background Art

[0002] Zirconium exists primarily as baddeleyite (ZrO2) and zircon (ZrSiO4) in the Earth's crust. Hafnium, on the other hand, does not exist as a separate mineral. It coexists naturally with zirconium, with no separate hafnium ore found. The hafnium content in natural zirconium is generally 2-3%. Therefore, heating the zirconium-hafnium mixed solution is necessary to effectively separate the zirconium and hafnium. However, current purification equipment can only heat and fractionate the zirconium-hafnium mixed solution, rather than stirring it. This results in low heating efficiency and poor fractionation results.

[0003] To address these issues, Chinese patent application CN222878037U discloses a zirconium-hafnium fractionation extraction device. The device comprises a separation box with a fractionation chamber disposed above the separation box. A rotating shaft is disposed within the fractionation chamber. Multiple sets of stirring blades are fixedly mounted on the rotating shaft. A cleaning plate is fixedly mounted at the bottom of the rotating shaft. The cleaning plate is in contact with a sealing plate disposed in the center of the separation box. This device continuously stirs the zirconium-hafnium mixed solution via the stirring blades while the heating wire heats it. This accelerates heating efficiency, enhances purification, and ensures quality.

[0004] The above device has the following problems during actual use: the heating wire of the device is fixed in one position, so heat can only be transferred from bottom to top, which makes the heat transfer method relatively single and heat cannot be transferred from multiple directions, resulting in poor mixing effect of heat and zirconium-hafnium mixed solution and low mixing efficiency. Summary of the Invention

[0005] The present invention provides a zirconium and hafnium separation and extraction device to solve the problem that the existing extraction device can only diffuse heat in a single direction.

[0006] In order to achieve the above object, the present application adopts the following technical scheme: a zirconium-hafnium separation and extraction device, comprising a processing cylinder with an inlet and an outlet, a discharge pipe connected to the processing cylinder, a rotating shaft arranged in the processing cylinder, a circular block, extraction mechanisms symmetrically arranged on both sides of the rotating shaft along the axial direction of the rotating shaft, a driving assembly for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the processing cylinder; the circular block is fixedly connected to the rotating shaft and attached to the inner wall of the processing cylinder; the extraction mechanism comprises a conduit, a hot air component, air passage assemblies symmetrically arranged on both sides of the conduit along the axial direction of the conduit, through holes opened in the circular block, and a power assembly for driving the conduit to rotate; the conduit is rotatably connected to the through holes; the hot air component is connected to the inner wall of the conduit; the air passage assemblies comprise a plurality of air passage portions equally arranged along the axial direction of the conduit; the air passage portion comprises a through pipe and through hole groups symmetrically opened on both sides of the through pipe along the length direction of the through pipe; the through pipe is in communication with the conduit; the through hole groups comprise a plurality of through holes equally opened on the through pipe along the length direction of the through pipe.

[0007] The principle and advantages of the present application are as follows: 1. The zirconium-hafnium mixed solution is placed into the processing cylinder through the inlet, and then hot air is discharged through the conduit, the through pipe, and finally the through holes. During the discharge of hot air, the hot air has a certain flow rate, thereby enabling the hot air to contact more zirconium-hafnium mixed solution, improving the utilization rate of hot air, and enabling the hot air to more efficiently distill the zirconium-hafnium mixed solution, thereby ensuring the purification effect.

[0008] 2. During the discharge of hot air, the rotating shaft drives the through pipe to move circumferentially, thereby expanding the discharge range of hot air, enabling the hot air to be fully and uniformly diffused in the processing cylinder, thereby further improving the utilization rate of hot air and enabling the hot air to more quickly distill and purify the zirconium-hafnium mixed solution.

[0009] 3. During the circumferential movement of the conduit, the conduit can also rotate under the action of the power assembly. Therefore, during the rotation of the conduit, the action range of hot air can be expanded again, thereby comprehensively improving the utilization rate of hot air and enabling the hot air to more completely heat the zirconium-hafnium mixed solution, further ensuring the purification quality of the zirconium-hafnium mixed solution.

[0010] 4. Since the through pipe moves circumferentially while also rotating, the through pipe can comprehensively and uniformly stir the zirconium-hafnium mixed solution, enabling the hot air to more efficiently mix with the zirconium-hafnium mixed solution, thereby accelerating the distillation progress of the hot air on the zirconium-hafnium mixed solution, shortening the distillation time of the zirconium-hafnium mixed solution, and improving the distillation and purification efficiency of the zirconium-hafnium mixed solution.

[0011] Further, the ventilation part further comprises a bidirectional screw, an auxiliary unit symmetrically arranged on both sides of the bidirectional screw along the length direction of the through pipe, and a moving unit for driving the bidirectional screw to rotate; the bidirectional screw is rotationally connected with the inner wall of the through pipe; the auxiliary unit comprises a side pipe, a guide rod, a nut seat, an auxiliary block, and a side hole opened on the through pipe; the side pipe is fixedly connected with the through pipe and communicates with the side hole; the guide rod is fixedly connected with the inner wall of the through pipe; the nut seat is threadedly connected with the bidirectional screw and slidably connected with the guide rod; the auxiliary block is fixedly connected with the nut seat and can slide in and out of the side pipe.

[0012] The side pipe is arranged to increase the exhaust path of the hot air, so that the hot air can be exhausted from both sides of the through pipe, thereby enriching the diversity of the hot air exhaust, enabling the hot air to heat and purify the zirconium-hafnium mixed solution from multiple paths, and further improving the processing efficiency of the zirconium-hafnium mixed solution.

[0013] During the exhaust of the hot air from the through hole and the side pipe, the exhaust flow of the hot air through the through hole and the side pipe can be adjusted by the mutual approach or separation of the two auxiliary blocks: when the two auxiliary blocks approach each other, the hot air is mainly exhausted from the upper and lower sides of the through pipe; when the two auxiliary blocks are separated from each other, the hot air is mainly exhausted from the left and right sides of the through pipe. Therefore, by adjusting the exhaust flow of the hot air, the exhaust effect of the hot air can be more effectively enhanced, enabling the hot air to perform more uniform distillation and purification treatment on the zirconium-hafnium mixed solution.

[0014] Further, the auxiliary unit further comprises an auxiliary member; the auxiliary member comprises a sliding pipe and a fixing block; the sliding pipe is slidably connected with the inner wall of the side pipe; the free ends of the bidirectional screw and the unidirectional screw extend into the sliding pipe, and the auxiliary block extends into the sliding pipe; the fixing block is fixedly connected with the auxiliary block and the sliding pipe, respectively.

[0015] The sliding pipe can reciprocate along the length direction of the side pipe under the drive of the auxiliary block. During the movement of the sliding pipe, the length of the sliding pipe can be relatively extended, thereby enhancing the stirring effect of the left and right sides of the through pipe on the zirconium-hafnium mixed solution, and further improving the stirring quality of the through pipe on the zirconium-hafnium mixed solution.

[0016] Meanwhile, during the movement of the sliding pipe, the hot air can be exhausted from near to far and from far to near relative to the side pipe, thereby further enhancing the exhaust effect of the hot air from the left and right sides of the through pipe, enabling the hot air to more completely purify the zirconium-hafnium mixed solution.

[0017] Further, the ventilation part further comprises a bidirectional screw, an auxiliary unit symmetrically arranged on both sides of the bidirectional screw along the length direction of the through pipe, and a moving unit for driving the bidirectional screw to rotate; the bidirectional screw is rotationally connected with the inner wall of the through pipe; the auxiliary unit comprises a side pipe, a guide rod, a nut seat, an auxiliary block, and a side hole opened on the through pipe; the side pipe is fixedly connected with the through pipe and communicates with the side hole; the guide rod is fixedly connected with the inner wall of the through pipe; the nut seat is threadedly connected with the bidirectional screw and slidably connected with the guide rod; the auxiliary block is fixedly connected with the nut seat and can slide in and out of the side pipe.

[0018] Through the vertical reciprocating movement of the linkage block, the linkage block can stir the hafnium-zirconium mixed solution in one step, so that the hafnium-zirconium mixed solution can be stirred in different directions, thereby accelerating the mixing efficiency of the hafnium-zirconium mixed solution and the hot air, and ensuring that the hafnium-zirconium mixed solution can be quickly heated and purified under the action of the hot air.

[0019] Further, a plurality of sealing blocks are equidistantly arranged along the length direction of the linkage block; the sealing blocks are fixedly connected with the linkage block, the through hole is located on the movement track of the sealing block, and the sealing block can slide in and out of the through hole.

[0020] Through the vertical reciprocating movement of the sealing block, the sealing block can intermittently block the through hole at the bottom of the through pipe. That is, during the blocking of the through hole at the bottom of the through pipe, the hot air can only flow from the through hole at the top of the through pipe. Therefore, by reducing the number of through holes discharging hot air, the flow rate of the hot air discharged through the through hole can be increased, the discharge effect of the hot air can be enhanced, and the hot air can be efficiently and comprehensively contacted and mixed with the hafnium-zirconium mixed solution, thereby improving the heating and purification quality.

[0021] Further, the air passage further comprises an exhaust unit; the exhaust unit comprises a piston cylinder, a piston block, a spring, a side pipe, an air pipe, and a side block; the piston cylinder is fixedly connected with the through pipe; the piston block is slidingly connected with the piston cylinder; the two ends of the spring are connected with the piston block and the piston cylinder respectively; the side pipe and the air pipe are in communication with the piston cylinder; the side pipe is in communication with the through pipe; the side block is fixedly connected with the linkage block; and the piston block is located on the movement track of the side block.

[0022] Through the cooperation of the piston block and the piston cylinder, the hot air can be discharged from different directions, further ensuring that the hot air can heat and mix the hafnium-zirconium mixture from multiple directions, thereby improving the utilization rate of the hot air and ensuring that the hot air can be more uniformly and fully mixed with the hafnium-zirconium mixed solution.

[0023] The piston cylinder is arranged to accelerate the flow rate of the hot air discharged through the air pipe, so that the hot air can flow a longer distance after being discharged through the air pipe, the hot air can be more fully contacted with the hafnium-zirconium mixed solution, the utilization rate of the hot air is further improved, and the purification quality of the hafnium-zirconium mixed solution by the hot air is ensured.

[0024] Further, the air passage further comprises an agitation unit; the agitation unit comprises a box body, a rotating shaft, a plurality of agitation blocks symmetrically arranged on both sides of the rotating shaft along the length direction of the through pipe, and a power member for driving the rotating shaft to rotate; the box body is fixedly connected with the through pipe; the rotating shaft is rotatably connected with the box body; the agitation block group comprises a plurality of agitation blocks equidistantly arranged along the circumferential direction of the rotating shaft; and the agitation blocks are fixedly connected with the rotating shaft.

[0025] The zirconium and hafnium mixed solution is stirred by the stirring block, thereby enriching the diversity of the stirring of the zirconium and hafnium mixed solution, so that the zirconium and hafnium mixed solution can be subjected to different forms of stirring treatment, thereby facilitating the zirconium and hafnium mixed solution to be stirred more fully and uniformly, i.e., ensuring the effect and quality of the heating and mixing of the zirconium and hafnium mixed solution.

[0026] Further, the annular rack is fixed on the processing cylinder, the power assembly is the first gear, the first gear is fixed on the guide pipe, and the first gear is engaged with the annular rack.

[0027] During the circumferential movement of the guide pipe, the first gear moves synchronously; during the circumferential movement of the first gear, the first gear drives the guide pipe to rotate through the engagement between the first gear and the annular rack. Therefore, the guide pipe can rotate while moving circumferentially.

[0028] Further, the movement unit is the second gear, the second gear is fixed on the bidirectional screw, and the sliding block is the first rack, which is engaged with the second gear.

[0029] During the vertical reciprocating movement of the first rack, the first rack drives the second gear to rotate through the engagement between the first rack and the second gear; during the rotation of the second gear, the bidirectional screw rotates synchronously.

[0030] To achieve the above object, the present application adopts the following technical scheme: a zirconium and hafnium separation and extraction method, comprising the following steps: Step (1): placing the zirconium and hafnium mixed solution into the processing cylinder through the inlet, and then diffusing the heat air range through the rotation of the pipe; Step (2): adjusting the flow of the heat air in the pipe through the action of the auxiliary block; Step (3): further diffusing and discharging the heat air by the piston cylinder; Step (4): further stirring the zirconium and hafnium mixed solution through the vertical reciprocating movement of the linkage block; Step (5): stirring the zirconium and hafnium mixed solution in different directions by the stirring block.

[0031] The principle and advantages of the present application are as follows: Through the revolution and rotation of the pipe, the zirconium and hafnium mixed solution can be fully stirred, and the discharge range of the heat air can be diffused, thereby ensuring the processing quality of the zirconium and hafnium mixed solution.

[0032] Through the auxiliary action of the vertical block and the stirring block on the pipe, the zirconium and hafnium mixed solution can be more efficiently stirred.

[0033] Through the joint action of the sliding pipe, the air pipe, the auxiliary block and the sealing block, the hot air discharging effect can be further enhanced, so that the hot air discharging efficiency is improved, and it is ensured that the hot air can be heated with the hafnium-zirconium mixed solution comprehensively and uniformly.

[0054] An annular rack 27 is further fixedly connected to the inner wall of the top of the processing cylinder 1; the power assembly is a first gear 28; the first gear 28 is fixedly connected with the guide pipe 5, and the first gear 28 is in meshing connection with the annular rack 27.

[0055] The movement unit is a second gear 29; the second gear 29 is fixedly connected with the bidirectional screw rod 9; the sliding block 16 is a first rack; the first rack is in meshing connection with the second gear 29.

[0056] The linkage unit includes a second rack 30, a linkage shaft 31, a third gear 32, a guide hole opened on the catheter 5, and a linkage part for driving the linkage shaft 31 to rotate; the second rack 30 is fixedly connected to the first rack; the linkage shaft 31 is rotatably connected to the inner wall of the catheter 5; the third gear 32 is fixedly connected to the linkage shaft 31, the third gear 32 can rotate in the guide hole, and the third gear 32 is engaged with the second rack 30.

[0059] Specific implementation process: The zirconium-hafnium mixed solution is placed into the processing cylinder 1 through the inlet. A hot air blower then directs the hot air along the conduit 5 and through the pipe 6, ultimately discharging it through the through hole 7. During this discharge, the hot air has a certain flow rate, allowing it to come into contact with more of the zirconium-hafnium mixed solution, thereby increasing its utilization rate and enabling it to more efficiently distill the zirconium-hafnium mixed solution, thereby ensuring the purification effect. During the distillation of the zirconium-hafnium mixed solution, the distilled gas is discharged through the exhaust pipe 2.

[0060] During the hot air discharge process, the motor is started, and the motor's output shaft drives the rotating shaft 3 to rotate. During the rotation of the rotating shaft 3, the rotating shaft 3 drives the through-tube 6 to move in a circumferential direction through the guide tube 5, thereby expanding the discharge range of the hot air and allowing the hot air to be fully and evenly diffused within the processing cylinder 1. This further improves the utilization rate of the hot air, allowing the hot air to more quickly distill and purify the zirconium-hafnium mixed solution.

[0061] During the circumferential motion of the catheter 5, the first gear 28 moves synchronously. During the circumferential motion of the first gear 28, the engagement between the first gear 28 and the annular rack 27 causes the first gear 28 to drive the catheter 5 to rotate. Therefore, the catheter 5 can rotate while performing circumferential motion.

[0062] Therefore, during the rotation of the conduit 5, the scope of action of the hot air can be further expanded, thereby comprehensively improving the utilization rate of the hot air, so that the hot air can heat the zirconium and hafnium mixed solution more thoroughly, further ensuring the purification quality of the zirconium and hafnium mixed solution.

[0063] Since the through pipe 6 can rotate while moving circumferentially, the through pipe 6 can fully and uniformly stir the zirconium hafnium mixed solution, so that the hot air can be more efficiently mixed with the zirconium hafnium mixed solution, thereby accelerating the distillation progress of the hot air on the zirconium hafnium mixed solution, shortening the distillation time of the zirconium hafnium mixed solution, and improving the distillation and purification efficiency of the zirconium hafnium mixed solution.

[0064] The side pipe 10 is arranged to increase the discharge path of the hot air, so that the hot air can be discharged from both sides of the through pipe 6, thereby enriching the diversity of the hot air discharge, so that the hot air can be heated and purified from multiple paths. The zirconium hafnium mixed solution, that is, further improves the processing efficiency of the zirconium hafnium mixed solution.

[0065] During the movement of the guide pipe 5, the output shaft of the air cylinder 33 drives the vertical block 34 to move vertically. During the movement of the vertical block 34, the disc moves synchronously. During the movement of the disc, the third rack 36 moves synchronously. During the movement of the third rack 36, the third rack 36 is engaged with the third gear 32, and the third gear 32 rotates. During the rotation of the third gear 32, the third gear 32 is engaged with the second rack 30, and the second rack 30 can move vertically. During the movement of the second rack 30, the first rack moves synchronously.

[0066] During the vertical reciprocating movement of the first rack, the first rack drives the second gear 29 to rotate through the engagement of the first rack and the second gear 29. During the rotation of the second gear 29, the bidirectional screw rod 9 rotates synchronously. During the rotation of the bidirectional screw rod 9, the distance between the two auxiliary blocks 13 can approach or move away from each other.

[0067] Therefore, during the discharge of the hot air from the through hole 7 and the side pipe 10 respectively, the discharge flow of the hot air through the through hole 7 and the side pipe 10 can be adjusted by the mutual approach or movement away of the two auxiliary blocks 13: when the two auxiliary blocks 13 approach each other, the hot air is mainly discharged from the upper and lower sides of the through pipe 6; when the two auxiliary blocks 13 move away from each other, the hot air is mainly discharged from the left and right sides of the through pipe 6. Therefore, by adjusting the discharge flow of the hot air, the discharge effect of the hot air can be more effectively enhanced, so that the hot air can be more uniformly distilled and purified from the zirconium hafnium mixed solution.

[0068] The sliding pipe 14 can move reciprocally along the length direction of the side pipe 10 under the drive of the auxiliary block 13. During the movement of the sliding pipe 14, the sliding pipe 14 can extend the length of the side pipe 10, thereby enhancing the stirring effect of the left and right sides of the through pipe 6 on the zirconium hafnium mixed solution, thereby further improving the stirring quality of the through pipe 6 on the zirconium hafnium mixed solution.

[0069] At the same time, the hot air can be discharged from the side pipe 10 from near to far and from near to far during the movement of the sliding pipe 14, thereby enhancing the effect of discharging the hot air from the left and right sides of the through pipe 6 again, so that the hot air can more completely purify the zirconium hafnium mixed solution.

[0070] During the vertical reciprocating movement of the first rack, the linkage block 17 moves synchronously. Through the vertical reciprocating movement of the linkage block 17, the linkage block 17 can stir the zirconium hafnium mixed solution in one step, so that the zirconium hafnium mixed solution can be stirred in different directions, thereby speeding up the mixing efficiency of the zirconium hafnium mixed solution and the hot air, and ensuring that the zirconium hafnium mixed solution can be quickly heated and purified under the action of the hot air.

[0071] During the movement of the linkage block 17, the sealing block 18 moves synchronously. Through the vertical reciprocating movement of the sealing block 18, the sealing block 18 can intermittently block the through hole 7 at the bottom of the through pipe 6. That is, during the blocking of the through hole 7 at the bottom of the through pipe 6, the hot air can only flow from the through hole 7 at the top of the through pipe 6. Therefore, by reducing the number of through holes 7 discharging hot air, the flow rate of hot air discharged through the through hole 7 can be increased, the discharging effect of hot air can be enhanced, and the hot air can be efficiently and comprehensively contacted and mixed with the zirconium hafnium mixed solution, thereby improving the heating and purification quality.

[0072] During the movement of the linkage block 17, the piston block 20 can be driven to move vertically under the joint action of the side block 37 and the spring 21. Therefore, through the cooperation of the piston block 20 and the piston cylinder 19, the hot air can be discharged from different directions, further ensuring that the hot air can be heated and mixed with the zirconium hafnium mixed solution from multiple directions, thereby improving the utilization rate of the hot air and ensuring that the hot air can be more uniformly and fully mixed with the zirconium hafnium mixed solution.

[0073] The piston cylinder 19 is provided to accelerate the flow rate of the hot air discharged through the air pipe 23, so that after the hot air is discharged through the air pipe 23, the hot air can flow a longer distance, the hot air can be more fully contacted with the zirconium hafnium mixed solution, the utilization rate of the hot air is further improved, and the purification quality of the hot air on the zirconium hafnium mixed solution is ensured.

[0074] During the vertical reciprocating movement of the first rack, the fourth gear is driven to rotate by the meshing of the first rack and the fourth gear. During the rotation of the rotating shaft 25, the stirring block 26 rotates synchronously.

[0075] During the rotation of the stirring block 26, the stirring block 26 stirs the zirconium hafnium mixed solution, thereby enriching the diversity of stirring the zirconium hafnium mixed solution, so that the zirconium hafnium mixed solution can be subjected to different forms of stirring treatment, thereby promoting the zirconium hafnium mixed solution to be more fully and uniformly stirred, thereby ensuring the effect and quality of heating and mixing of the zirconium hafnium mixed solution.

[0076] In summary, by discharging hot air from multiple directions and stirring the zirconium and hafnium mixed solution in different forms, the heating and purification effect of the zirconium and hafnium mixed solution is comprehensively enhanced, so that the separation of zirconium and hafnium can be quickly and efficiently completed, that is, the separation and purification quality is improved.
