The mesh 10 protects the bottom air stirring device and, when bubbles rise to the mesh 10, are dispersed, forming denser bubbles, thus improving the efficiency and quality of air stirring. A drain port 3 is installed at the bottom of the left side wall of the conical bottom 101.

[0027] The air mixing device includes an air outlet pipe 8 laid on the bottom 101 of the conical trough.

This forms a large number of microbubbles in the electrode liquid. The rising and mixing action of these bubbles in the liquid achieves mixing, thereby uniformizing the electrolyte concentration, reducing the concentration difference of the solution, and helping to form a uniform and dense oxide film, thus improving the quality and performance of the oxide film.

A handle 604 is arranged at the upper end of the filter plate 603 and used for conveniently taking the filter plate 603.

[0031] Specifically, the electrolyte after heat exchange enters the tank body 601 through the inlet 606, and then flows out of the outlet 605 after being filtered by the filter plate 603; in this process, the number of the filter plates 603 can be several, and the installation positions of the filter plates 603 can be selected according to actual conditions; when the filter plates 603 are installed, the sidewall of the filter plate 603 is moved downwards along the vertical clamping groove 602 until the bottom of the filter plate 603 is clamped into the clamping groove 607.
