[0031] 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 creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figure 1-6, the present utility model provides a technical solution: a fine processing and defluorination device for lithium sulfate solution, comprising a reaction kettle 10, a support frame 101, an observation board 20, a motor 30, a rotating shaft 301, a stirring rod 303, a scraper 304, a cleaning rod 305, a discharge port 306, a blocking plate 307, an inlet pipe opening 308, a rotating rod 309, a feed box 40, a blanking port 401 and a diversion plate 402;

[0033] This fine processing and defluorination device for lithium sulfate solution is convenient for mixing materials and increasing the contact area of the reaction solution. The specific implementation method is as follows:

[0034] A diversion mechanism is arranged inside the reaction kettle 10, and the diversion mechanism includes: the surface of the reaction kettle 10 is fixedly connected with a feed box 40, and the bottom of the feed box 40 is fixedly connected with a plurality of blanking ports 401.

An opening is embedded on the surface of the reaction kettle 10, and the end of the blanking port 401 is inserted into the opening inside the reaction kettle 10. The diversion plate 402 is arranged in a spiral blade shape, and the diversion plate 402 is rotatably connected to the reaction kettle 10.

[0035] Pour the reaction solution into the inside of the feed box 40. At this time, the reaction solution enters the inside of the blanking port 401 through the feed box 40 and enters the inside of the reaction kettle 10 through the blanking port 401. At this time, the reaction solution falls on the surface of the diversion plate 402 through the blanking port 401, causing the reaction solution to move downward along the surface of the diversion plate 402, so that the reaction solution falls on the surface of the lithium sulfate solution through the diversion plate 402. When starting the motor 30, the motor 30 drives the rotating shaft 301 to rotate inside the reaction kettle 10. At the same time, the rotating shaft 301 drives the diversion plate 402 on its surface to rotate, so that the end of the diversion plate 402 rotates on the surface of the lithium sulfate solution. At this time, the reaction solution falls on the surface of the lithium sulfate solution through the end of the diversion plate 402, enabling it to quickly contact the lithium sulfate solution.

[0036] This fine processing and defluorination device for lithium sulfate solution can facilitate stirring and prevent blockage of the discharge port 306 during blanking. The specific implementation method is as follows:

[0037] The reactor 10 is set as a hollow cylindrical shell structure, and a support frame 101 is fixedly connected to the bottom of the reactor 10; a rotating mechanism is arranged inside the reactor 10, and the rotating mechanism includes: an observation plate 20 is embedded on the surface of the reactor 10, and a motor 30 is installed on the surface of the reactor 10.

The stirring rod 303 can stir the lithium sulfate solution, making the reaction between the lithium sulfate solution and the reaction solution more uniform. At the same time, the rotating shaft 301 drives the scraping plate 304 to rotate, so that the scraping plate 304 rotates on the bottom surface of the reactor 10 to clean the inner wall of the reactor 10 and prevent sediment from accumulating and sticking to the inner wall. At this time, the solution inside the reactor 10 can be observed through the observation plate 20. When the reaction is completed, let it stand still, and pump out the reacted solution above through the pumping mechanism. Take out the blocking plate 307 from the bottom of the outlet 306. At this time, the blocking plate 307 loses its blockage of the outlet 306, and the sediment inside the reactor 10 can be discharged through the outlet 306. At this time, start the motor 30. The motor 30 drives the rotating shaft 301 to rotate. The rotating shaft 301 drives the rotating rod 309 on its surface to rotate. The rotating rod 309 drives the cleaning rod 305 on its surface to rotate, so that the cleaning rod 305 cleans the inside of the outlet 306 and prevents sediment from accumulating on the inner wall of the outlet 306.
