[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1 to 4 , the present utility model provides a hafnium metal production device, including a base 1, a purification reaction tank 9 and a reduction furnace 10. The purification reaction tank 9 and the reduction furnace 10 are existing devices. The purification reaction tank 9 is fixedly installed on the left side of the upper surface of the base 1, and a back plate 12 is fixedly installed on the right side of the upper surface of the base 1. The back plate 12 is vertically arranged and is used to provide an installation foundation for other components. The back plate 12 is provided with an L-shaped through groove 11. The L-shaped through groove 11 is smoothly transitioned by a vertical section, a horizontal section and an arc section. The vertical section is located on the left side of the horizontal section, and the vertical section is higher than the horizontal section.

[0024] A first electric cylinder 15, a reduction motor 4 and a transfer mechanism 2 are installed on the front side of the back plate 12. The first electric cylinder 15 is located above the vertical section, the reduction motor 4 is located above the horizontal section, and the transfer mechanism 2 is located on the right side of the horizontal section. A crucible 13 is placed inside the reduction furnace 10. A flange 14 is provided at the upper end of the circumferential side of the crucible 13. The lower end of the push rod of the first electric cylinder 15 is fixedly installed with a sealing cover 7 for covering the crucible 13. The reduction motor 4 is equipped with a transmission mechanism 5 for swinging the reduction furnace 10, and the transfer mechanism 2 is equipped with a hook 3 for moving the crucible 13.

[0025] The reduction motor 4 can swing the reduction furnace 10 along the L-shaped through groove 11 via the transmission mechanism 5, moving the reduction furnace 10 and the crucible 13 to the top of the vertical section (i.e., the high position station) or to the right end of the horizontal section (i.e., the low position station). The sealing cover 7 capable of performing a lifting action via the first electric cylinder 15 can seal the crucible 13 at the high position station, and the hook 3 that can swing via the transfer mechanism 2 can pick up, place and move the crucible 13 at the low position station.

[0026] Specifically, please refer to Figure 2 , the transmission mechanism 5 includes a swing arm 54 and a support rod 51. The output end of the reduction motor 4 penetrates the back plate 12 and is fixedly installed with one end of the swing arm 54. Here, a spline connection method is preferably used between the output end of the reduction motor 4 and the swing arm 54 to ensure the stability of torque transmission. A long slot 53 is provided at the other end of the swing arm 54. A support rod 51 is fixedly installed at the rear side of the reduction furnace 10. The support rod 51 is slidably assembled in the L-shaped through groove 11 and the long slot 53. When the swing arm 54 swings, it can apply a swinging force to the support rod 51 via the long slot 53, and the support rod 51 is restricted in the L-shaped through groove 11 and can only move along the L-shaped through groove 11, thereby driving the reduction furnace 10 to move to the high position station or the low position station.

[0027] The transmission mechanism 5 further includes two sleeves 52 rotatably assembled on the support rod 51. One sleeve 52 is located in the L-shaped through groove 11, and the other sleeve 52 is located in the long slot 53. The sleeves 52 are used to reduce the friction between the support rod 51 and the L-shaped through groove 11, and between the support rod 51 and the long slot 53. In addition, the support rod 51 is located at the middle of the upper end of the reduction furnace 10, ensuring that the center of gravity of the reduction furnace 10 is below the support rod 51, which is beneficial for the reduction furnace 10 to maintain a vertical use posture.

[0028] Specifically, please refer to Figure 2, the transfer mechanism 2 includes an electric lead screw module 25 and a second electric cylinder 21. The electric lead screw module 25 is fixedly installed on the front side of the back plate 12. A base 22 is rotatably installed on the upper side of the slide table of the electric lead screw module 25. A second electric cylinder 21 is fixedly installed on the upper side of the base 22. The push rod of the second electric cylinder 21 is fixedly assembled with the hook 3. The electric lead screw module 25 and the hook 3 are horizontally arranged, and the second electric cylinder 21 is vertically arranged. When the electric lead screw module 25 horizontally moves the slide table, the hook 3 can be horizontally translated left and right through the base 22 and the second electric cylinder 21. The second electric cylinder 21 is used to lift and move the hook 3. The base 22 enables the second electric cylinder 21 and the hook 3 to have the ability to flip.

[0029] The transfer mechanism 2 further includes a rack 23 and a gear 24. The rack 23 is fixedly installed on the front side of the back plate 12 and is parallel to the upper side of the electric lead screw module 25. The base 22 is fixedly installed with the gear 24, and the rear side of the gear 24 is meshed and assembled with the rack 23. When the base 22 is driven to translate, the meshing relationship between the gear 24 and the rack 23 can make the base 22 rotate synchronously. That is, when the base 22 translates to the left, the base 22 can also rotate clockwise, thereby rotating the second electric cylinder 21 and the hook 3 clockwise; when the base 22 translates to the right, the base 22 can also rotate counterclockwise, thereby rotating the second electric cylinder 21 and the hook 3 counterclockwise; here, "clockwise" and "counterclockwise" are based on Figure 2 the direction of the top view in

[0030] Please refer to Figure 4 , the hook 3 is mainly composed of a U-shaped hook body and a connecting plate welded together. The hook 3 is used to be clamped with the crucible 13. When clamped, the hook 3 is located below the flange 14, and at the same time, it is also convenient to remove the crucible 13 from the hook 3.

[0031] Two roller belts 8 are fixedly installed on the front side of the back plate 12. Both of the two roller belts 8 are vertically arranged. One roller belt 8 is located on the left side of the L-shaped through groove 11, and the other roller belt 8 is located on the right side of the L-shaped through groove 11. The roller belt 8 is an existing component composed of a frame body and rollers evenly rotatably assembled in the frame body. The left roller belt 8 is used to block the reduction furnace 10 at the high-position station to ensure the vertical state of the reduction furnace 10 and facilitate the sealing of the sealing cover 7; while the right roller belt 8 is used to block the reduction furnace 10 at the low-position station to ensure the vertical state of the reduction furnace 10 and facilitate the clamping of the hook 3.

[0032] In addition, please refer to Figure 4, a clamping jaw assembly 6 for clamping the flange 14 is installed on the sealing cover 7; the clamping jaw assembly 6 is an existing component composed of a jaw arm, a connecting rod, a linear bearing seat, and a push-pull electromagnet. The jaw arm is provided with a groove matching the flange 14. The clamping jaw assembly 6 can move up and down with the sealing cover 7. When the sealing cover 7 is buckled on the crucible 13, the push-pull electromagnet in the clamping jaw assembly 6 retracts the push rod upward, and a pair of jaw arms are pulled up through the linear bearing seat. Since the jaw arms are rotationally assembled on the sealing cover 7 through the connecting rod, the jaw arms can move close to the crucible 13 until the groove is clamped with the flange 14, further strengthening the firmness of the buckling of the sealing cover 7; before the sealing cover 7 moves up, first control the push-pull electromagnet in the clamping jaw assembly 6 to extend the push rod downward, and the jaw arms are opened after transmission, releasing the clamping of the groove and the flange 14.

[0033] The back plate 12 is also fixedly installed with a control cabinet and a control panel. Electrical appliances such as the purification reaction tank 9, the reduction furnace 10, the reduction motor 4, the first electric cylinder 15, the second electric cylinder 21, and the electric lead screw module 25 are all electrically connected to the controller in the control cabinet, and can be uniformly controlled through the control panel.

[0034] The working principle of this embodiment:

[0035] In the initial state, the transfer mechanism 2 drives the hook 3 to flip to the right to avoid affecting the placement action of the crucible 13. The reduction motor 4 can swing the reduction furnace 10 to the lower working position to the right along the L-shaped through groove 11 through the transmission mechanism 5. Prepare the magnesium melt through an external melting furnace, place the magnesium melt into the crucible 13 and place the crucible 13 into the reduction furnace 10;

[0036] The reduction motor 4 then swings the reduction furnace 10 to the higher working position to the left along the L-shaped through groove 11 through the transmission mechanism 5. At this time, the first electric cylinder 15 moves down the sealing cover 7 to cover the crucible 13, and the clamping jaw assembly 6 clamps the flange 14 for further locking. Argon gas is added for protection and heating in the reduction furnace 10 to keep it in a molten state. Hafnium tetrachloride input from the purification reaction tank 9 reacts with the magnesium melt to obtain a sponge hafnium mixture;

[0037] After completion, the clamping jaw assembly 6 first releases the clamping, the first electric cylinder 15 drives the sealing cover 7 to reset upward, and the reduction furnace 10 is transferred to the lower working position again. At this time, the transfer mechanism 2 flips the hook 3 to the left, so that the hook 3 is clamped with the crucible 13 and is located below the flange 14. After the second electric cylinder 21 jacks up the hook 3, the crucible 13 can be taken out. At this time, the transfer mechanism 2 flips and resets to the right, which is convenient to remove the crucible 13 from the hook 3 and transfer it to the distillation furnace, and is also convenient to put a new crucible 13 filled with magnesium melt into the reduction furnace 10 to repeat the above actions for a new round of reduction reaction.
