Abstract

This utility model discloses a continuous operation lithium precipitation reactor, belonging to the field of chemical equipment. It includes a reactor body, a first feeding device, a stirring device, a lifting pipe, a discharge port, and at least one sodium carbonate feeding pipe. The reactor body is formed by an elliptical upper head, a cylindrical section, and an elliptical lower head connected sequentially from top to bottom. The first feeding device is located on the elliptical upper head and is used to inject lithium-containing reactants into the reactor body. The stirring device is used to stir the reactants injected into the reactor body. The lifting pipe is located on the inner wall of the reactor body, with its upper and lower ends located in the upper and lower spaces of the reactor body, respectively. The discharge port is located on the outer wall of the cylindrical section and laterally connects to the interior of the lifting pipe. The sodium carbonate feeding pipe is located on the outer wall of the cylindrical section. One end of the sodium carbonate feeding pipe connects to the interior of the reactor body, and the other end extends downwards at an angle away from the cylindrical section. This utility model has a simple structure, enables continuous production, ensures lithium carbonate production efficiency, and avoids blockage of the feed port by lithium carbonate precipitation.
