The rotating shaft 112 drives the stirring blade 113 and the crossbar 114 to rotate. The stirring blade 113 mixes the lithium-containing solution and carbide. During the mixing process, the stirring spiral 116 can improve the mixing effect during the reaction. The hot gas generated by the heating of the liquid reaction is discharged through the exhaust pipe 12. During the exhaust, the hot gas is treated by the activated carbon filter plate 13 to prevent the waste gas from polluting the air. After the reaction is completed, the liquid reaction produces lithium carbonate crystals. The waste liquid at the bottom of the reaction tank 1 is discharged from the drain pipe 8. The collection box 6 is pulled out from the reaction tank 1 using the sealing plate 7 to collect the lithium carbonate crystals. Finally, the water inlet pipe 910 can be opened to deliver clean water to the reaction tank 1. The water is stirred by the stirring mechanism 11 to clean the inside of the tank. The wastewater is discharged from the drain pipe 8.
