Drying system capable of preventing agglomeration of calcium carbonate powder

Abstract

The invention discloses a drying system capable of preventing agglomeration of calcium carbonate powder. The drying system comprises an oven shell, a feeding unit, and a heat supply unit for providingheat; the oven shell is provided with a feed port, a discharge port and an exhaust port; the feeding unit is formed by joining multiple feeding modules end to end; each feeding module comprises a traction roller, and a conveying belt arranged on the traction roller; the head end of the first feeding module is positioned under the feed port; the tail end of the final feeding module is positioned above the discharge port; a dispersing device is arranged in the oven shell, is mounted in the oven shell, and is positioned under discharge ends of the feeding modules; the dispersing device comprisesa leading plate, an outer shell and a centrifugal device; the leading plate takes the shape of a funnel with large top and small bottom; and a large end of the leading plate is positioned under a discharge end of the conveying belt. The drying system can effectively prevent agglomeration of calcium carbonate during drying, can effectively improves the product quality, and meanwhile, achieves a better drying effect.

Description

technical field [0001] The invention relates to a drying device, in particular to a drying system for preventing caking of calcium carbonate powder. Background technique [0002] Calcium carbonate is an inorganic compound, commonly known as limestone, limestone, stone powder, marble, calcite, is a compound, the chemical formula is CaCO 3 , Neutral, basically insoluble in water, soluble in acid. It is a common substance on earth and exists in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also the main component of animal bones or shells. Calcium carbonate is an important building material, widely used in industry, and also a common reagent in middle and high school chemistry (commonly used to react with hydrochloric acid to generate CO 2 Wait). [0003] In the process of processing calcium carbonate, it needs to be dried to facilitate subsequent processing and production. In the existing technology, the drying of calcium carbonate is ge...

Problems solved by technology

[0004] This utility model makes calcium carbonate dry when transported on the conveyor belt. Although the setting of the conveyor belt can prolong the drying time of calcium carbonate, when the calcium carbonate is transported on the conveyor belt, the calcium carbonate is always on the conveyor belt. Keep still, only the surface of the conveyor belt can be dried, and the calcium carbonate near the conveyor belt is not dried thoroughly; especially when drying powdered calcium carbonate, the calcium carbonate powder is easy to agglomerate on the conveyor belt during drying, resulting in product poor quality
