The combined use of the first hydraulic cylinder 14 and the push plate 15 can realize the automatic pushing of raw materials in the collection box 13. When the raw materials in the collection box 13 reach a certain amount, the first hydraulic cylinder 14 drives the push plate 15 to push the raw materials into the leaching barrel 17 without manual operation, thereby improving the production efficiency and automation level.

[0033] Specifically, the setting of the filter 34 can effectively intercept impurities and particles in the liquid, so that the effective ingredients in the liquid can be preliminarily purified. This filtering method is simple and efficient, ensuring the efficiency and accuracy of the purification process.

[0034] See also Figure 1 , Figure 2 and Figure 3 A loading port 2 is provided on the upper surface of the grinding box 1, a first motor 3 is arranged on the back of the grinding box 1, and a grinding roller 4 is fixedly connected to the output shaft of the first motor 3.

[0035] Specifically, the grinding roller 4 is driven by the first motor 3 to achieve efficient grinding of the raw material, ensure that the particle size of the raw material is uniform, and provide a good raw material basis for the subsequent leaching and purification process.

The heating controller 29 at the bottom of the leaching barrel 17 can accurately control the temperature during the leaching process to ensure that the effective ingredients in the raw material can be fully dissolved. This precise temperature control can not only improve the leaching efficiency, but also reduce energy consumption and reduce production costs. The leachate is transported to the separation box 31 through the transport pipe 30, and the separated liquid is introduced into the purification box 33 for further purification using the connecting pipe 32.

At the same time, the combined use of the separation box 31 and the purification box 33 can also achieve continuous production and improve the production efficiency of the equipment.

[0036] Working principle: when separating and extracting zirconium and hafnium, first, the zirconium and hafnium ore can enter the grinding box 1 through the feeding port 2, and then the first motor 3 can drive the output shaft of the first motor 3 to rotate, and then the ground zirconium and hafnium ore powder can enter the transparent discharge pipe 5. When quantitative addition is performed, when the mineral powder in the transparent discharge pipe 5 reaches a certain amount, the hinge seat 7 set between the fixed mounting bracket 6 on the right side of the transparent discharge pipe 5 can drive the use angle of the closed control panel 8 to change according to the actual situation, so as to control the amount of discharge, and the power of the electric telescopic rod 10 can drive the use of the closed control panel 8 fixedly installed at one end of the electric telescopic rod 10. The angle is changed by the hinge seat 7, so that the mineral powder can enter the interior of the collecting box 13, and then the pushing plate 15 is pushed inside the collecting box 13 by the power of the first hydraulic cylinder 14, so that a certain amount of mineral powder can be pushed into the leaching barrel 17 through the collecting box 13 for the next operation, and then the leaching agent can be introduced into the leaching barrel 17 through the action of the feeding port 18, and the mineral powder and the leaching agent are mixed. Synchronously, before leaching and mixing the mineral powder and the leaching agent, the temperature inside the leaching barrel 17 can be more accurately controlled by the action of the heating controller 29 set at the bottom of the leaching barrel 17, and then the second motor 21 can be driven by the power of the second motor 21. The output shaft is fixedly connected to the rotation of the three-leaf connecting plate 19. When the three-leaf connecting plate 19 rotates, the second gear 22 fixedly installed on the upper surface of the three-leaf connecting plate 19 can be driven to mesh with the outer surface of the first gear 20 fixedly installed inside the leaching barrel 17. When the second gear 22 is meshed with the first gear 20, the third gear 24 connected to the outer surface of the first connecting rod 23 fixedly installed inside the second gear 22 can be driven to rotate. When the third gear 24 rotates, the fourth gear 25 meshing with the outer surface of the third gear 24 can be synchronously driven to rotate. Then, the second connecting rod 26 fixedly installed inside the fourth gear 25 can drive the connecting block 27 and the stirring blade 28 to rotate in a circular arc trajectory inside the leaching barrel 17, so that the stirring blade 28 entering the leaching barrel 17 can be driven. The leaching agent and the mineral powder are fully mixed, and after mixing, they can enter the interior of the separation box 31 through the action of the transport pipe 30. By utilizing the difference in solubility of zirconium and hafnium in a specific solvent, efficient and rapid separation can be achieved. When purifying, the separated solution is allowed to enter the interior of the purification box 33 through the action of the connecting pipe 32. Then, the impurities in the separated solution can be filtered through the action of the filter 34. Then, the filtered solution can enter the right side of the purification box 33. After entering, the power of the third hydraulic cylinder 38 can be used to drive the baffle 39 to move downward, so that the baffle 39 can completely cover the filter 34. Then, the solution can be evaporated and purified through the action of the heating wire 40.The purified object can be opened by the clamping plate 41 to open the purification box 33, and then the purified material can be taken out, and the unpurified impurities can be discharged through the through slot on the right side of the purification box 33, and when the surface of the filter 34 is cleaned after long-term use, the scraper 37 can be driven up and down by the second hydraulic cylinder 36 to clean the surface of the filter 34.
