Description

Technical Field

[0001] This utility model relates to the field of drying technology, and in particular to a drying device for lightweight calcium carbonate powder. Background Technology

[0002] Light calcium carbonate, also known as precipitated calcium carbonate, is produced through chemical synthesis and has wide applications in various industries such as plastics, rubber, coatings, and papermaking. During its production, the calcium carbonate precipitate has a high water content and needs to be dehydrated and dried to produce the finished product. Existing equipment for dehydrating and drying light calcium carbonate generally uses hot steam or hot air circulation. While some equipment can dry light calcium carbonate, it has several problems. For example, a top-moving sieve is often insufficient for efficiently breaking up clumps of calcium carbonate, requiring prolonged and repeated sieving to achieve breakage. Even then, it sometimes only breaks the calcium carbonate into small fragments, not into powder, resulting in low production efficiency. Furthermore, when drying calcium carbonate raw materials that are prone to clumping after absorbing moisture, the equipment cannot ensure uniform heating, limiting the drying effect.

[0003] Currently, a light calcium carbonate powder drying device has shortcomings:

[0004] 1. During the drying process of light calcium carbonate powder, the powder may be locally overheated or clump together, resulting in incomplete drying and reduced efficiency.

[0005] 2. During the drying process of light calcium carbonate powder, air circulation is not possible, resulting in high humidity inside the device, which will affect the drying effect. Utility Model Content

[0006] The purpose of this utility model is to provide a drying device for lightweight calcium carbonate powder, which includes a first motor, a stirring paddle, and a first rotating shaft. The first motor drives the first rotating shaft to rotate, and the first rotating shaft drives the stirring paddle to rotate, thereby achieving stirring and preventing the powder from clumping or overheating in some areas during the drying process. The device also includes a second motor, a second rotating shaft, an impeller, a first air inlet, a second air inlet, and an air outlet. The second motor drives the second rotating shaft, and the second rotating shaft drives the impeller. The impeller draws in moisture from the device and discharges it through the air outlet.
