[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model discloses an extraction device for separating zirconium and hafnium, comprising a base 1, a square frame 2 fixed to the top of the base 1, a stirring tank 3 and an extraction tank 4 disposed inside the square frame 2, an upper positioning circular plate 5 fixed to the top of the stirring tank 3, and a lower positioning circular plate 6 fixed to the bottom of the stirring tank 3, the stirring tank 3 being placed between the upper positioning circular plate 5 and the lower positioning circular plate 6, multiple stabilizing components disposed on the bottom side of the outside of the stirring tank 3, each of the multiple stabilizing components including a stabilizing side plate 7, the bottom of the stabilizing side plate 7 being fixedly connected to the top of the lower positioning circular plate 6, and a locking block 8 fixed to the outside of the stirring tank 3, the inner sides of the multiple locking blocks 8 being arc-shaped, and the back of the locking block 8 being connected to the front side of the stabilizing side plate 7, a locking spring 9 being fixed between the locking block 8 and the stabilizing side plate 7. In the prior art, when extracting and separating zirconium and hafnium, it is necessary to add The extractant is used for extraction, but during the mixing process, the outside of the container receiving the liquid is prone to instability due to the stirring force. In severe cases, it may tilt, which will affect the extraction efficiency. To address this issue, multiple stabilizing components can be installed on the bottom side of the outside of the mixing tank 3. When the extractant is mixed by the stirring components, if there is a large shaking on the outside of the mixing tank 3, the locking blocks 8 inside the multiple stabilizing components will slope outward. Then, the locking springs 9 fixed to the outside of the multiple locking blocks 8 and the stabilizing side plate 7 are used. Since the stabilizing side plate 7 is fixed to the lower positioning circular plate 6, the locking springs 9 will reduce the magnitude of the slope generated on the outside of the multiple locking blocks 8, thereby maintaining the stability of the mixing tank 3 and improving the extraction rate.

[0024] The mixing tank 3 is equipped with a stirring assembly, which includes a stirring rod 10. The stirring rod 10 is rotatably connected to the inner side of the mixing tank 3. Multiple arc-shaped support rods 11 are evenly fixed to the outside of the stirring rod 10. A drive motor 12 is fixed to the top of the upper positioning circular plate 5. The output end of the drive motor 12 extends to the inner side of the mixing tank 3 and is fixedly connected to the top of the stirring rod 10. The zirconium-hafnium-containing stock solution and the extractant are added to the inner side of the mixing tank 3 through two funnels 19, respectively. Then, the drive motor 12 is started to drive the stirring rod 10 and the multiple arc-shaped support rods 11 to rotate, thereby facilitating the thorough mixing of the zirconium-hafnium-containing stock solution and the extractant.

[0025] A heater 13 is fixed to the bottom of the extraction tank 4. The bottom of the heater 13 is fixedly connected to the top of the frame 2. A controller 14 is fixed to the outside of the heater 13. After stirring, the liquid inside the stirring tank 3 flows into the inside of the extraction tank 4 through the first flow pipe 15. Then, the heater 13 is turned on by the controller 14 to facilitate the extraction of the liquid inside the extraction tank 4. The extraction tank 4 and the stirring tank 3 are connected by the first flow pipe 15. A second flow pipe 16 is fixed to the right side of the extraction tank 4. A valve body 17 is provided at the top of both the first flow pipe 15 and the second flow pipe 16 to facilitate the control of the liquid flow. A receiving filter plate 18 is fixed inside the extraction tank 4. The receiving filter plate 18 is located below the first flow pipe 15. By setting the receiving filter plate 18, it is convenient to separate the zirconium and hafnium after the mixed liquid flows into the inside of the extraction tank 4 and by using the heater 13.

[0026] Two funnels 19 are fixed to the top of the upper positioning circular plate 5. Both funnels 19 extend into the inside of the stirring tank 3, and both funnels 19 have a shell-like opening inside. By setting two shell-like funnels 19, the flow area of ​​the zirconium-hafnium-containing stock solution and the extractant is expanded. The top of the extraction tank 4 is provided with a cover plate 20 to facilitate the protection of the inner end of the extraction tank 4. Hanging rings 21 are fixed on both sides of the outer side of the frame 2 to facilitate the hanging of other extraction tools.

[0027] Working principle: First, the zirconium-hafnium-containing stock solution and the extractant are added to the inside of the stirring tank 3 through two funnels 19. Then, the drive motor 12 is started, which drives the stirring rod 10 and multiple arc-shaped support rods 11 to rotate, thereby facilitating the thorough mixing of the zirconium-hafnium-containing stock solution and the extractant. After stirring, the liquid inside the stirring tank 3 flows into the inside of the extraction tank 4 through the first flow pipe 15. Then, the heater 13 is turned on by the controller 14, which facilitates the extraction of the liquid inside the extraction tank 4. By setting up a receiving filter plate 18, the zirconium-hafnium is easily separated after extraction. When there is a large amount of shaking outside the stirring tank 3, the locking blocks 8 inside the multiple stabilizing components will slope outward. Then, the locking springs 9 fixed to the outside of the multiple locking blocks 8 and the stabilizing side plate 7 are used. Since the stabilizing side plate 7 is fixed to the lower positioning circular plate 6, the locking springs 9 will reduce the magnitude of the slope generated outside the multiple locking blocks 8, thereby maintaining the stability of the stirring tank 3 and improving the extraction rate.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
