Problems solved by technology

[0002] The feeding point of the conventional co-precipitation reactor is fixed and single, and the length of the feeding pipe is not enough, so it can only submerge the reaction liquid level. Since the horizontal dispersion effect of the solution is obvious by stirring, the vertical dispersion effect is poor. On the horizontal plane, the relative supersaturation of the solution is large, the homogeneous nucleation effect is significant, and the crystal form precipitation of small particles is easy to obtain, and the crystal grains are not easy to grow further, resulting in uneven particle growth speed. During the precipitation process, there is a particle size distribution The two-level trend is not conducive to the normal distribution of material particle size and affects product quality

Abstract

The invention relates to a co-precipitation reaction kettle. The co-precipitation reaction kettle comprises a kettle body, wherein the kettle body is provided with a stirring apparatus with stirring blades and a feeding apparatus, the feeding apparatus comprises a feeding pipe, and the bottom end of the feeding pipe is disposed on the bottom of the kettle body. In the structure, material inlets are formed in the side wall of the feeding pipe. In the structure, the length of the feeding pipe is 1.8 m. In the structure, 4 to 7 material inlets are provided. In the structure, the number of the material inlets is six. In the structure, the material inlets are successively enlarged from the upper part to the lower part. In the structure, a distance between two material inlets is 50mm.

Description

technical field [0001] The invention relates to a reaction container, in particular to a co-precipitation reaction kettle. Background technique [0002] The feeding point of the conventional co-precipitation reactor is fixed and single, and the length of the feeding pipe is not enough, so it can only submerge the reaction liquid level. Since the horizontal dispersion effect of the solution is obvious by stirring, the vertical dispersion effect is poor. On the horizontal plane, the relative supersaturation of the solution is large, the homogeneous nucleation effect is significant, and the crystal form precipitation of small particles is easy to obtain, and the crystal grains are not easy to grow further, resulting in uneven particle growth speed. During the precipitation process, there is a particle size distribution The two-level trend is not conducive to the normal distribution of material particle size and affects product quality.
