TECHNICAL FIELD

[0001] The utility model relates to the technical field of nickel carbonate production, in particular to multifunctional integrated precipitation reactor. BACKGROUND

[0002] Nickel carbonate is an important inorganic compound, mainly used in battery manufacturing, catalysts and other industrial applications. Its wide application is due to its excellent chemical properties and relatively low production cost. The production of nickel carbonate is usually carried out by solution precipitation method, which involves mixing nickel-containing solution with carbonate solution to form nickel carbonate precipitate.

[0003] The patent with publication number CN221847136U discloses a reaction kettle for nickel carbonate production, which comprises a reaction kettle body, an installation frame is arranged on the top of the inner cavity of the reaction kettle body, a filter screen is arranged in the installation frame, a stirring roller is rotatably installed on the bottom wall of the inner cavity of the reaction kettle body, the top end of the stirring roller penetrates through the filter screen, and the stirring roller is rotatably connected with the filter screen, a first motor is fixedly installed at the bottom of the reaction kettle body, and the output end of the first motor is drivingly connected with the stirring roller. The utility model can filter and roll the input raw materials, crush some large-particle raw materials, make the stirring more uniform, uniformly scatter the filtered and rolled raw materials in the reaction kettle body through the air blowing mechanism, make the mixture of the stirring roller more uniform, reduce the mixing time of the raw materials, and improve the working efficiency during stirring.

[0004] Although the above-mentioned prior art improves the uniformity and working efficiency during stirring by adopting the design of filter screen and stirring roller, the solution and precipitate are still mixed together after the formation of nickel carbonate precipitate by the direct output mode through the discharge pipe, which leads to the failure to realize the effective separation of the precipitate.

Such separate process not only occupies a large space, increases the equipment investment and maintenance cost, but also easily leads to the waste of energy and materials. In view of this, the multifunctional integrated precipitation reactor is proposed to integrate the precipitation, separation and drying processes in one, so as to improve the production efficiency and reduce the resource consumption.
