[0023] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.
[0024] It should be noted that in the embodiments of the present application, the first feeding pipe 2 and the second feeding pipe 3 are arranged at the top of the kettle body 5, the refined lithium chloride mother liquor enters the reaction cavity through the first feeding pipe 2, the refined sodium carbonate solution enters the reaction cavity through the second feeding pipe 3, and the sodium carbonate solution and the lithium chloride mother liquor are fully reacted in the reaction cavity. Control valves can be arranged on the first feeding pipe 2 and the second feeding pipe 3 respectively to control the feeding amount of the lithium chloride mother liquor and the sodium carbonate, so as to meet the process requirements.
[0025] As Figures 1 to 3 As shown, an embodiment of this utility model provides a lithium deposition reactor. The lithium deposition reactor includes a reactor body 5, a drive unit, a stirring unit, and a crushing unit. The reactor body 5 defines a reaction chamber. The reactor body 5 is equipped with a first feed pipe 2, a second feed pipe 3, and a discharge pipe 12 that communicate with the reaction chamber. A drive unit is located on the reactor body 5, comprising a drive component 1 and a stirring shaft 14. The top end of the stirring shaft 14 extends out of the reaction chamber and connects to the output shaft of the drive component 1, while the bottom end of the stirring shaft 14 extends to the bottom of the reaction chamber. The stirring unit includes multiple stirring blades 15 located between the top and bottom ends, spaced circumferentially along the stirring shaft 14, and each stirring blade 15 is connected to the stirring shaft 14. The crushing unit includes multiple crushing blades connected to the bottom end, spaced circumferentially along the stirring shaft 14. Each crushing blade includes a main blade segment 6 connected at an angle to the main blade segment 6 and a crushing blade segment 8. The crushing blade segment 8 is located on the side of the main blade segment 6 facing the bottom wall of the reaction chamber and is inclined towards the bottom wall of the reaction chamber, so that the crushing blade segment 8 and the bottom wall of the reaction chamber together crush the blocky material at the bottom of the reaction chamber.
[0026] In the above technical solution, the driving component 1 drives the stirring blades 15 and the crushing blades to rotate via the stirring shaft 14. The stirring blades 15 can fully stir the materials in the reaction chamber. Under the action of the stirring blades 15, the lithium chloride mother liquor and the sodium carbonate solution are fully mixed and reacted to generate a lithium carbonate slurry with lumpy substances. The lumpy substances fall to the bottom of the reaction chamber under the action of gravity. Then, with the stirring of the crushing blades, the crushing blade section 8 and the bottom wall of the reaction chamber jointly squeeze and rub the lumpy substances, which can crush the lumpy substances that have fallen to the bottom of the reaction chamber. The crushed substances flow with the lithium carbonate slurry to the discharge pipe 12 and are pumped to the buffer tank of the horizontal belt filter by the power pump 16 for solid-liquid separation. In this way, by continuously crushing the lumpy substances that fall to the bottom of the reaction chamber by the crushing part, the probability of blockage of the discharge pipe 12 and the power pump 16 can be reduced, so that the lithium precipitation reactor can operate continuously and stably for a long time, thereby improving production efficiency.

[0029] It should be noted that in the embodiment of the utility model, the main body leaf segment 6 is broken leaf segment 8 and the bottom wall of the reaction cavity is inclined, which means that along the axis of the stirring shaft 14, from the top end of the stirring shaft 14 to the bottom end of the stirring shaft 14, the distance between the broken leaf segment 8 and the vertical plane where the main body leaf segment 6 is located gradually increases.
[0030] Preferably, in the embodiment of the utility model, the stirring shaft 14 drives the stirring blade 15 and the broken blade to rotate clockwise, Figure 3 The broken leaf segment 8 in the broken blade is located on the left side of the main body leaf segment 6, so that during the rotation of the broken blade, the broken leaf segment 8 and the bottom wall of the reaction cavity can jointly crush the blocky material; in an embodiment, if the stirring shaft 14 drives the stirring blade 15 and the broken blade to rotate counterclockwise, then Figure 3 The broken leaf segment 8 in the broken blade is located on the right side of the main body leaf segment 6.
