The invention discloses a metallurgical electrolytic tank device comprising an electrolytic tank, a cathode and an anode. The cathode and the anode are arranged in the electrolytic tank, and an electrolytic power source is connected between the cathode and the anode. The cathode and the anode are vertically arranged in the electrolytic tank, the anode is wrapped with a protective sleeve made of aceramic material, and the protective sleeve at least wraps the portion, immersed in an electrolyte, of the anode. The anode is wrapped with the protective sleeve, thus anode consumption caused by a reaction generated by the anode in the electrolysis process is avoided, the service life of the anode is prolonged, the electrolysis use cost is reduced, and meanwhile the electrolysis effect is also guaranteed.
