Description

Technical Field

[0001] The utility model relates to the technical field of extraction equipment, in particular to extraction equipment for separation of hafnium and zirconium. Background Art

[0002] Zirconium is a metallic element, symbol Zr (zirconium). It is silver-grey, hard, has a high melting point and is corrosion-resistant. It is used to make alloys, flash powder, etc. It is also used as a degassing agent in a vacuum. Tightly compressed pure zirconium is used as the outer jacket of uranium rods in nuclear reactors. Hafnium is also a metallic element. In nature, hafnium often coexists with zirconium. Zircon-containing minerals all contain hafnium. Hafnium and zirconium are isomorphous. Hafnium is mainly found in zircon. The amount of HfO2 in zircon used in industry is 0.5%-2%. The HfO2 content of beryllium zircon in secondary zircon ore can be as high as 15%. There is also a metamorphic zircon, qubilt, which contains more than 5% HfO2. The reserves of the latter two minerals are small and have not yet been used in industry. Hafnium is mainly recovered in the process of zircon production.

[0003] The Chinese utility model patent with patent application number 202322956266.0 provides an extraction device in the hafnium and zirconium separation process. By setting up a tank body, a shell and a stirring shaft, it is convenient to evenly mix the hafnium zirconium and the extract liquid and stir them fully. A scraper, a heating device and a supporting plate are set to facilitate uniform distillation of the hafnium zirconium, thereby achieving the extraction effect.

[0004] However, during the use of the above-mentioned equipment, it was found that during distillation, a certain amount of gas would be generated.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] See also Figure 1-Figure 3 The extraction equipment for separating hafnium and zirconium shown in the figure comprises a mixing box 1, an extraction box 2 is arranged on one side of the mixing box 1, a connecting pipe 5 is connected to the top of the extraction box 2, a cooling assembly 6 is arranged on the connecting pipe 5, and the extraction box 2 is connected to the collecting box 3 through the connecting pipe 5;

[0021] A motor 11 is installed on the top of the mixing box 1, and a rotating shaft 12 is connected to the output end of the motor 11. A plurality of stirring blades 13 are fixedly arranged on the rotating shaft 12. A connecting rod 14 is fixedly connected to the bottom of the rotating shaft 12. Cleaning plates 15 are installed at the bottom and both sides of the connecting rod 14. A feeding port 16 is opened on the top of the mixing box 1, and a discharging port 17 is arranged at the bottom of the mixing box 1.

[0022] The discharge port 17 is connected to a connecting pipe 4, a valve 41 is provided on the connecting pipe 4, one end of the connecting pipe 4 is connected to one side of the extraction box 2, and the mixing box 1 is connected to the extraction box 2 through the connecting pipe 4;

[0023] A control panel 21 is provided on the outer side of the extraction box 2. The control panel 21 is connected to a heating plate 23. The heating plate 23 is provided at the bottom of the extraction box 2. A carrying plate 24 is provided above the heating plate 23. A liquid outlet 22 is provided on one side of the extraction box 2.

[0024] The cooling assembly 6 includes a liquid storage tank 64, a ventilation hole 66 is provided on the top of the liquid storage tank 64, one end of the liquid storage tank 64 is connected to a liquid inlet pipe 62, the liquid storage tank 64 is connected to the cooling box 61 through the liquid inlet pipe 62, a spiral tube 611 is provided in the cooling box 61, one end of the spiral tube 611 is connected to the liquid inlet pipe 62, the other end of the spiral tube 611 is connected to the liquid outlet pipe 63, the liquid outlet pipe 63 is connected to the liquid storage tank 64 through a pump 65, and a liquid infusion port 67 is provided on the top of the liquid storage tank 64;

[0025] A door plate 31 is rotatably connected to one side of the collection box 3 , and a collection tank 32 is provided inside the collection box 3 .

[0026] In this solution, when the equipment is in use, the material and the extract enter the mixing box 1 from the feed port 16, and the motor 11 is used to drive the rotating shaft 12 to rotate rapidly. At the same time, the material and the extract are mixed and stirred by using multiple groups of stirring blades 13 fixedly arranged on the rotating shaft 12 to form a mixed liquid. After the mixing is completed, the staff opens the valve 41 on the connecting pipe 4 so that the mixed liquid can enter the extraction box 2 through the connecting pipe 4. When the mixed liquid flows into the connecting pipe 4 from the discharge port 17, the motor 11 is used to drive the rotating shaft 12 to control the connecting rod 14 to rotate, so that the cleaning plate 15 on the connecting rod 14 can clean the mixed liquid attached to the inner wall of the mixing box 1, so that the cleaned mixed liquid can also flow into the extraction box 2 along the connecting pipe 4.

[0027] In the extraction box 2, hafnium and zirconium are separated by distillation. A heating plate 23 is provided at the bottom of the extraction box 2. The heating plate 23 is controlled by a control panel 21 on the outside of the extraction box 2. The heating plate 23 is connected to an external power supply component. The mixed liquid flowing in from the connecting pipe 1 4 falls on the carrier plate 24. When distilling, the control panel 21 is used to control the power supply component to supply power to the heating plate 23, so that the heating element inside the heating plate 23 can generate heat to distill the mixed liquid. The gas formed by distillation enters the connecting pipe 2 5 through the top of the extraction box 2. The gas entering the connecting pipe 2 5 will be cooled by the cooling box 61. The liquid outlet 22 on one side of the extraction box 2 is convenient for discharging the extracted liquid in the extraction box 2.

[0028] During cooling, the pump 65 is used to extract the coolant in the liquid storage tank 64, and the coolant enters the spiral tube 611 through the liquid inlet pipe 62, and flows into the liquid storage tank 64 from the liquid outlet pipe 63 connected to one end of the spiral tube 611. When the coolant passes through the spiral tube 611, the contact between the spiral tube 611 and the connecting tube 2 5 allows the coolant to absorb the heat of the gas in the connecting tube 2 5 in the cooling box 61, so that the gas in the connecting tube 2 5 in the cooling box 61 is liquefied, and flows into the collecting box 3 along the connecting tube 2 5, thereby preventing the gas from always being in the extraction box 2, preventing the gas from always being in contact with the mixed liquid, causing part of the gas to dissolve in the mixed liquid and affecting the extraction effect of the mixed liquid. The spiral tube 611 can increase the contact area with the connecting tube 2 5, so that the gas in the connecting tube 2 5 can be fully liquefied. The ventilation hole 66 on the liquid storage tank 64 is provided with a filter screen, and the ventilation hole 66 facilitates the heat dissipation of the coolant in the liquid storage tank 64;

[0029] The liquid entering the collection box 3 will fall into the collection tank 32. The staff can take out the collection tank 32 by rotating the door panel 31, so as to facilitate the treatment of the liquid.
