During the preparation process of lithium carbonate, carbon dioxide needs to be introduced into the carbonization tower to hydrogenate the lithium carbonate.

[0003] For example, patent number CN218250244U discloses a device for continuous carbonization and purification of lithium carbonate in a fixed bed, which belongs to the technical field of lithium carbonate purification equipment; it includes a tower body, a cooling coil is provided inside the tower body, and a stirring shaft 1 and a stirring shaft 2 are provided directly below the cooling coil, the stirring shaft 1 and the stirring shaft 2 are distributed vertically, and the stirring mechanism is fixedly connected to the stirring shaft 1 and the stirring shaft 2 respectively, the stirring mechanism includes a stirring rib and a stirring support rod, and a strip cylinder is fixedly connected to the surface of the stirring support rod, and two air intake devices are provided in the lower end of the tower body, which are distributed vertically, and the air intake device includes a shell fixedly connected to the inner wall of the tower body and an inflation pipe connected to one side of the shell, the interior of the shell is a hollow structure, and a vent is provided on the surface of the shell, and the other end of the inflation pipe passes through the tower body and extends to the outside thereof; it solves the problems of low energy conservation and low reaction efficiency; the cooling structure of the lithium carbonate continuous carbonization purification equipment in this patent is only installed in the upper half, resulting in low cooling efficiency. At the same time, its internal structure is relatively complex and cannot be disassembled, making it difficult to clean and maintain the internal structure of the device after use, which affects the service life of the device.

[0004] Therefore, in view of the problem that the cooling structure and solution cooling efficiency of the above-mentioned continuous carbonization and purification equipment for lithium carbonate are low, and its internal structure is relatively complex and cannot be disassembled, resulting in difficulty in cleaning and maintaining the internal structure of the device after use, a continuous carbonization and purification equipment for preparing high-quality lithium carbonate can be designed. By setting a cooling mechanism on the outside of the reaction vessel, the solution can be continuously and evenly cooled to improve the cooling efficiency. By setting a detachable stirring and gas supply structure, the cleaning and maintenance of each structure can be facilitated. Utility Model Content
