Abstract

The utility model discloses an acid leaching impurity removal device for zirconium oxide processing, which belongs to the technical field of zirconium oxide production equipment and structurally comprises a reaction unit, a diluted hydrochloric acid feeding unit, a diluted ammonia water feeding unit and a control system. According to the utility model, the online thermometer and the online pH meter on the reaction kettle are used for monitoring in real time and feeding data back to the control system, so that the temperature and the pH value are accurately controlled, the reaction conditions are ensured to be stable, zirconium ions are prevented from being hydrolyzed in advance or ferric ions are prevented from being precipitated incompletely, and meanwhile, the reaction temperature is reduced. The diluted hydrochloric acid and diluted ammonia water feeding unit is electrically connected with the control system, the feeding amount can be accurately controlled, the stirring speed of the stirring assembly is controlled by the control system, so that solutions are fully mixed, and the device is simple and convenient to operate, high in automation degree, easy to maintain and capable of improving the production efficiency and ensuring the purity and the quality of final zirconium oxide products.
