The ends of the transverse partition 2 and the vertical partition 3 abut against the inner wall of the electrolytic cell 1, and the bottom of the transverse partition 2 and the top of the vertical partition 3 extend to the middle of the inner cavity of the electrolytic cell 1, so as to facilitate the circulation of the electrolyte. The transverse partition 2 and the vertical partition 3 divide the electrolytic cell 1 into the first anode cell 4, the first cathode cell 5, the second anode cell 6 behind the transverse partition 2, and the third anode cell 7, the second cathode cell 8, and the fourth anode cell 9 in front of the transverse partition 2 along the length direction. The volume size of the first anode cell 4 is equal to the volume size of the second anode cell 6, the volume size of the third anode cell 7 is equal to the volume size of the fourth anode cell 9, which is smaller than the volume size of the first cathode cell 5, and the volume size of the first cathode cell 5 is equal to the volume size of the second cathode cell 8. In this way, the setting of double anode cells and single cathode cells is achieved, which effectively improves the electrolysis efficiency.

The first anode tank 4, the second anode tank 6, the third anode tank 7, and the fourth anode tank 9 are used to hold crude gallium, which undergoes an oxidation reaction and dissolves in the electrolyte to form gallate ions, and the gallate ions in the electrolyte move to the first cathode tank 5 and the second cathode tank 8 to undergo a reduction reaction to form metallic gallium. A slag discharge port 24 is provided at the bottom of the first anode tank 4, the first cathode tank 5, the second anode tank 6, the third anode tank 7, the second cathode tank 8, and the fourth anode tank 9, and the slag discharge port 24 facilitates the discharge of impurities from the slag discharge port 24 after the crude gallium is precipitated, thereby facilitating the next impurity removal treatment of the crude gallium.

[0027] The first anode tank 4, the first cathode tank 5, the second anode tank 6, the third anode tank 7, the second cathode tank 8 and the fourth anode tank 9 are all composed of a structure with a rectangular parallelepiped at the upper part and an inverted quadrangular pyramid at the lower part. The first anode tank 4 and the third anode tank 7 are provided with a first anode plate 10, and the first cathode tank 5 and the second cathode tank 8 are provided with a cathode plate 11, the cathode plate 11 includes a cathode connecting plate 16, a cathode sheet 17 and a cathode connector 18, the cathode connecting plate 16 is provided with a plurality of cathode connectors 18 on the top, and the cathode connector 18 is used to connect the wire, and the cathode sheets 17 are evenly distributed at both ends of the bottom of the cathode connecting plate 16, and the cathode sheets 17 at both ends of the bottom of the cathode connecting plate 16 are respectively located in the first cathode tank 5 and the second cathode tank 8.
