With the rapid development of the new energy vehicle industry, especially the growth in demand for lithium-ion batteries, the strategic position of lithium hydroxide has become increasingly prominent and market demand has continued to increase.

[0003] The existing lithium hydroxide preparation generally involves mixing raw materials for lithium hydroxide preparation and reacting them in a reactor to obtain lithium hydroxide slurry.

The rotating rod is rotatably connected to the base 7, and the rotating rod is provided with an acceleration mechanism 8.

[0020] like Figure 1 and Figure 3 As shown, the acceleration mechanism 8 includes a guide frame 81, a screw 82, a moving part 83 and a moving plate 84.

[0021] When using the utility model, firstly, the reactor 1 is placed in the lithium hydroxide preparation area, the upper cover 2 is connected to the reactor 1 by bolts, and then the raw materials for lithium hydroxide preparation are mixed and put into the reactor 1 from the feeding pipe 5 on the upper cover 2. The base 7 can support the reactor 1. After the feeding is completed, the motor 3 is started to rotate the rotating rod, drive the stirring frame 4 to rotate, stir the raw materials, and obtain lithium hydroxide slurry after the raw materials are fully reacted. Then the discharge pipe 6 is opened to discharge the lithium hydroxide slurry from the reactor 1 for collection. The internal situation of the reactor 1 can be observed through the upper cover 2. After the motor 3 is started, the rotating rod is rotated to drive the screw 82 to rotate, so that the moving part 83 moves up and down, and drives the moving plate 84 to slide up and down on the guide frame 81, thereby being able to flip the lithium hydroxide raw materials up and down while stirring, so that the raw materials are mixed evenly and the lithium hydroxide preparation efficiency is improved.

[0023] The demisting mechanism 9 of the device can be used to scrape off the water mist on the upper cover 2. When water mist condenses on the top of the reactor 1, the hand wheel 93 is rotated to drive the connecting piece 92 to rotate, so that the water scraper 91 rotates to scrape off the water mist on the upper cover 2, thereby scraping off the water mist condensed on the upper cover 2, making it easier to observe the reaction conditions inside the reactor 1.
