[0002] In the process of preparing calcium carbonate powder, limestone will produce calcium carbonate of different particle sizes and small-particle limestone. Therefore, the preparation of calcium carbonate powder needs to be dried and screened through a vibrating screen or other screening devices. At present, the common calcium carbonate powder screening system can generally only screen calcium carbonate powder from small-particle limestone, and cannot further screen smaller and lighter calcium carbonate powder from larger and heavier calcium carbonate powder. And this production process cannot be sustained, and a large amount of manpower needs to be invested, which greatly increases the production cost of calcium carbonate. Therefore, the screening device and drying device in the prior art are not only limited in screening varieties, but also have high drying costs. In addition, the entire production process cannot be sustained and automated, thereby reducing production efficiency and increasing production costs. Utility Model Content

[0003] Therefore, in order to solve the above-mentioned deficiencies, the utility model provides an automated drying and sorting system for precipitated calcium carbonate powder, which can not only screen out multiple varieties of calcium carbonate powder, but also solve the problems of calcium carbonate powder agglomeration, difficulty in completely drying out the moisture, easy moisture absorption of the powder, and moisture increase. This system can not only greatly reduce the manpower requirements in the preparation process of calcium carbonate powder, but also improve the drying and sorting efficiency, thereby greatly reducing the production cost of calcium carbonate powder. The utility model dries the calcium carbonate filter cake twice, effectively dries and depolymerizes the calcium carbonate filter cake, effectively controls the moisture content of calcium carbonate, and maintains good dispersibility of the powder. Continuous production of drying-grading and screening is realized, production costs are reduced, and the production efficiency of calcium carbonate powder is improved.

[0005] Furthermore, the A drying module includes a dryer A and a dryer B; the dryer A and the dryer B are docked.

[0006] Furthermore; the B dispersion module includes a lift A, an air pump, and a classifier; the classifier includes a material tank for loading calcium carbonate, a classifying wheel arranged at the discharge end of the material tank, and a breaking up component arranged at the feed end of the material tank, and the breaking up component includes a motor arranged on the material tank; the air pumps are respectively arranged on both sides of the inner wall of the classifier.

[0007] Furthermore, the feed port of the elevator A corresponds to the outlet of the dryer B.

The high-quality calcium carbonate powder enters the grading module through the elevator of the dispersion module. Air pumps are installed on both sides of the grading module. The air pump can effectively disperse the high-quality calcium carbonate powder in the grading module, thereby effectively avoiding the calcium carbonate powder from blocking the feed or discharge port.
