Abstract

The invention discloses a closed calcium carbonate reaction device. The closed calcium carbonate reaction device comprises a reaction still. A transmission shaft penetrating through the reaction still is arranged above the reaction still. The transmission shaft stretches into the reaction still. A stirring vane is arranged at the bottom end of the transmission shaft. Cavities are formed in the transmission shaft and the middle of the stirring vane. The cavity of the transmission shaft and the cavity of the stirring vane are connected to form a channel which is enterable from the exterior of the reaction still. Through holes are formed in the surface of the stirring vane. A discharge port is formed in the bottom of the reaction still. The closed calcium carbonate reaction device is reasonable in design and high in continuous operational capacity, discharging is carried out through the cavity of the transmission shaft and the cavity of the stirring vane, excessive impurities are prevented from being brought in, meanwhile, it is guaranteed that the reaction is continuously conducted in the forward direction, and generated intermediates are reduced.

Description

Technical field [0001] The invention belongs to the field of chemical engineering, and specifically relates to a calcium carbonate sealed reaction device. Background technique [0002] Calcium carbonate is usually synthesized by reaction in a reactor, and taken out after the temperature drops. However, under heating conditions, calcium carbonate is not very stable and may react with other substances to form impurities, or due to insufficient reaction to generate a certain amount of intermediates, which affects the purity of the product. Summary of the invention [0003] Object of the invention: The object of the present invention is to provide a closed reaction device for calcium carbonate in view of the shortcomings of the prior art. [0004] Technical scheme: In order to achieve the above objective, the present invention is specifically accomplished as follows: a calcium carbonate sealed reaction device, including a reactor, above the reactor is provided with a transmission shaft...
