The invention discloses a production system of high-purity manganese carbonate for a high-density trimanganese tetroxide precursor, and relates to the technical field of metallurgical chemical production devices. In allusion to the technical problems that in the prior art, heating is nonuniform and the situation inside a reaction kettle cannot be mastered in real time, a control cabinet in coordination with the reaction kettle is used for achieving control, the discharge pipes of pipelines for supplying gas, an ammonia solution and a manganese sulfate solution which serve as three raw materials are overlapped up and down in a disc type, and in a unique staggered discharge opening mode, the three raw materials can be converged together better; after completion of a synthesis reaction inside the reaction kettle, a disc-type precipitant solution pipeline sprays out a precipitant, so that manganese carbonate crystal nuclei can more easily adsorb new precipitant crystal nuclei and microcrystals to form manganese carbonate particles which sink to the bottom of the reaction kettle; a heat-conducting coil inside the reaction kettle divides the reaction kettle into an inner part and an outer part, and under the rotation of a stirrer, with the coil as an axis, up-and-down circulating flow is achieved to uniformly heat internal reactants, so as to solve the problems in the prior art.
Description
technical field [0001] The invention relates to the technical field of metallurgical and chemical production equipment, in particular to a production system for high-density trimanganese tetraoxide precursor and high-purity manganese carbonate. Background technique [0002] In recent years, in order to gradually solve the three major problems of energy shortage, greenhouse gas and air pollution that restrict the current economic development, a climax of the development of new energy industry has been set off in the world. Some developed countries have successively issued a series of encouraging policies to stimulate new Development of energy vehicles. As a green energy storage secondary battery, lithium-ion battery has the advantages of high working voltage, high energy density, long cycle life, low self-discharge rate, no memory effect, and no environmental pollution. The market has achieved rapid development, and a large new energy industry has been formed, which has rece...
