A kind of reaction kettle with net cover type stirrer

Abstract

The invention discloses a reaction kettle of a grill type stirrer, relates to the technical field of production of high-density trimanganese tetraoxide precursor high-purity manganese carbonate, in particular to a high-purity manganese carbonate precursor used for producing high-density trimanganese tetraoxide precursor The reaction kettle of the net cover type agitator adopts blade type agitation for the prior art. During the agitation process, the moving track distance of the agitated raw materials is short, and the intermingling is uneven, which directly affects the reaction rate, resulting in manganese carbonate generated during the reaction process. The number of crystal nuclei is small, the crystal nuclei are small, and the technical problems of low reaction efficiency. Using a unique multi-layer grille stirrer combined with a coil heater can make the raw material of high-purity manganese carbonate being stirred move axially and radially. , Accelerate the speed of molecular movement and increase the probability of collision, thus completely solving the problem of small number and small crystal nuclei of manganese carbonate produced in the internal reaction process of the traditional reactor, and improving the reaction efficiency.

Description

technical field [0001] The invention relates to the technical field of production of high-density trimanganese tetroxide precursor high-purity manganese carbonate, in particular to a reaction kettle with a grille stirrer for producing high-density trimanganese tetraoxide precursor 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. In the past ten years, it has achiev...

Problems solved by technology

[0005] The invention provides a reaction kettle with a mesh cover type agitator, which is used to solve the problem that the blade type agitation is used in the prior art. During the agitation process, the moving track distance of the agitated raw materials is short, and the mixing is uneven, which directly affects the reaction rate and leads to reaction The number of manganese carbonate crystal nuclei produced in the process is small, the crystal nuclei are small, and the technical problems of low reaction efficiency
