[0002] High-purity strontium chloride (SrCl2) is an important chemical raw material widely used in electronics, optics, pharmaceuticals, and the nuclear industry. Its purity has a crucial impact on the performance of the final product. The preparation of high-purity strontium chloride involves dissolving pure strontium chloride in water, adding various reagents, and then reacting the solution. After the reaction, the reaction mixture needs to be filtered. However, because the reagents are usually added directly to the reaction vessel through the inlet, they cannot be evenly distributed, resulting in poor mixing efficiency and effectiveness, thus affecting the purity and yield of the high-purity strontium chloride.

[0003] Therefore, a multi-stage filtration device for the preparation of high-purity strontium chloride has been developed that can effectively improve the mixing efficiency and effect of the reaction solution, ensuring the purity and yield of high-purity strontium chloride. Utility Model Content

Detailed Implementation

The preparation tank 2 is connected to the upper side of the base 1. The support 3 is connected to the upper middle part of the preparation tank 2. The feed hopper 4 is connected to the upper left part of the preparation tank 2. The motor 6 is connected to the inner upper part of the support 3. The stirring rod is connected to the output shaft of the motor 6. The stirring rod 7 is rotatably connected to the preparation tank 2. The liquid outlet pipe 9 is connected to the lower side of the preparation tank 2. Three stirring blades 11 are connected to the lower part of the stirring rod 7, and each stirring blade 11 communicates with the stirring rod 7. Ten liquid inlets 13 are opened on the upper side of each stirring blade 11. The first filter plate 14 is snapped into the inside of the feed hopper 4. The first side door 15 is rotatably connected to the left side of the feed hopper 4. The first side door 15 is equipped with a handle for easy gripping. The liquid outlet pipe 9 is fitted with a second side door 16, which has a handle for easy gripping. The lower part of the liquid outlet pipe 9 is fitted with a second filter plate 17. The preparation tank 2 is equipped with a temperature assembly, which includes a temperature sensor 8 and a heating wire 80. The temperature sensor 8 is connected to the front of the preparation tank 2, and the heating wire 80 is connected inside the preparation tank 2. The heating wire 80 is electrically connected to the temperature sensor 8. A liquid addition assembly is provided between the support 3 and the stirring rod 7. The liquid addition assembly includes a liquid addition pipe 5 and a connecting sleeve 10. The liquid addition pipe 5 is fitted to the rear of the support 3. The connecting sleeve 10 is rotatably connected to the upper part of the stirring rod 7. The connecting sleeve 10 communicates with the stirring rod 7. The liquid addition pipe 5 is connected to the connecting sleeve 10. The preparation tank 2 is also equipped with a partition assembly, which includes a partition plate 12 and a solenoid valve 18. The partition plate 12 is connected to the lower part of the preparation tank 2, and the solenoid valve 18 is provided on the partition plate 12.

[0021] When using this invention, first place the base 1 in the high-purity strontium chloride preparation area, then pour the weighed pure strontium chloride into the feed hopper 4. The first filter plate 14 filters the pure strontium chloride, allowing pieces of strontium chloride of the appropriate size to enter the preparation tank 2. Larger pieces of pure strontium chloride remain on the first filter plate 14, making it easier for workers to crush them before adding them to the preparation tank 2, thus improving the dissolution efficiency of the pure strontium chloride. Then, pour an appropriate amount of water from the feed hopper 4 into the preparation tank 2 to dissolve the pure strontium chloride in the water. After the pure strontium chloride dissolves, sequentially introduce 30% hydrogen peroxide, hydrochloric acid, and sulfuric acid into the liquid addition pipe 5, then flow from the connecting sleeve 10 into the stirring rod 7, and finally discharge from the liquid addition port 13 into the preparation tank 2. During the addition of liquid, the motor 6 is started, driving the stirring rod 7 and the stirring blade 11 to rotate, stirring the solution evenly. This effectively improves the mixing efficiency and effect of the reaction solution, ensuring the purity and yield of high-purity strontium chloride. Then, the heating wire 80 is used to heat the solution, and the temperature sensor 8 senses the temperature in the preparation tank 2, keeping the solution at 40°C for 2 hours. After that, the solenoid valve 18 is opened, allowing the reacted solution to be discharged from the outlet pipe 9 through the partition 12. The reaction solution is then filtered through the second filter plate 17, and the filtrate is evaporated and crystallized to obtain high-purity strontium chloride. The first side door 15 and the second side door 16 can be opened to easily clean the first filter plate 14 and the second filter plate 17.
