A reaction apparatus for preparing calcium carbonate whiskers from ammonia-soda waste liquid

Abstract

This utility model relates to the field of calcium carbonate whisker preparation technology from ammonia-soda waste liquid, and discloses a reaction device for preparing calcium carbonate whiskers from ammonia-soda waste liquid, comprising: a reaction cylinder with a top cover; two feed pipes located on the cover; a discharge valve located at the bottom of the reaction cylinder; and at least one corner stirring mechanism, including a corner stirring motor fixed at the bottom corner of the reaction cylinder and stirring blades connected thereto. The corner stirring mechanism and the central stirring mechanism work together to significantly improve the mixing effect of the reactants. The corner stirring motor drives the stirring blades to stir at the bottom corner of the reaction cylinder, ensuring that the material at the bottom of the reaction cylinder is fully mixed and dispersed, avoiding local oversaturation. At the same time, the central stirring motor drives the central rod to rotate through a reducer, and the stirring blades on the central rod form a strong stirring vortex inside the reaction cylinder, further promoting the uniform mixing of the reactants.
