[0002] When preparing lithium carbonate by recycling battery cathode materials, the wet process element extraction method is usually adopted. The ternary powder of lithium nickel cobalt manganese oxide is leached by acid, chemically purified, and deeply purified or separated by extraction to obtain sulfates. The lithium-containing solution is added with sodium carbonate and evaporated and concentrated to obtain lithium carbonate.
[0003] When the existing high-purity lithium carbonate preparation device for battery cathode material recycling is in use, it is usually necessary to use a pH detector to detect the acidity and alkalinity of the reaction solution. The staff determines the addition dosage of various chemical catalysts according to the detection data. However, the existing device does not have a wiping structure for the probe of the pH detector, resulting in solution residue at the probe part after each detection, affecting the reading result.
[0004] Therefore, for the above-mentioned existing high-purity lithium carbonate preparation device for battery cathode material recycling, which does not have the function of wiping the probe of the pH detector and causes errors in the results, a high-purity lithium carbonate preparation device for battery cathode material recycling can be designed. By setting an electric push rod, its telescopic end will push the servo motor and the sponge head close to the pH detector until the sponge head fits with the probe, and then the servo motor is started. The rotating shaft of the servo motor will drive the sponge head to rotate, so as to wipe the probe. Content of the Utility Model
