Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate production, in particular to a calcium carbonate concentrator. Background Art

[0002] A calcium carbonate concentrator is a mechanical device used to concentrate calcium carbonate suspension. It is usually applicable to fields such as mines, chemical industry, and wastewater treatment, and is used to separate calcium carbonate solids from the suspension.

[0003] In the prior art, generally, the suspension is fully mixed in the concentrator through the stirring system in the calcium carbonate concentrator, so that calcium carbonate particles are dispersed in water. Under the action of stirring and gravity, the calcium carbonate particles gradually settle in water to achieve solid-liquid separation. However, the traditional stirring system is fixed in the concentrator shell through a rotating shaft. Although it can make the position of the stirring system change in its own rotating direction, it is difficult to change the position in other directions. This limits the stirring range of the stirring system for the suspension, making it difficult for the suspension to be fully mixed in the concentrator, and resulting in a poor solid-liquid separation effect.
