In order to recycle the electrolytic waste liquid, purification equipment will be used to purify the electrolytic waste liquid. Generally, specific extraction agents are used to extract and purify the electrolytic waste liquid.

[0003] The extraction of the existing purification device is mainly to add an extractant to the electrolytic waste liquid and mix it evenly, but the mixing efficiency of the extractant and the electrolytic waste liquid is not high. At the same time, the method of introducing the extractant and the electrolytic waste liquid into the purification cylinder in sequence will result in a long waiting time for adding materials, and it is not convenient to effectively pre-mix the materials during the loading process. In addition, the concentrated feeding positions of the extractant or the electrolytic waste liquid make the processing pressure of the stirring mechanism for rapid mixing relatively high.
