The cathode body 14 is arranged in a tubular shape to increase the surface area and improve the electrolysis efficiency. At this time, the temperature regulating mechanism 5 cools the cathode body 14 to a suitable temperature so that the connected gallium crystallizes to the surface. After the electrolysis is completed, the cathode body 14 is moved upward out of the liquid surface by the moving mechanism 3. At this time, the temperature of the cathode body 14 is made higher than the melting temperature of the electrolytic gallium by the temperature regulating mechanism 5.

[0059] In the present application, when the temperature of the cathode body 14 is controlled, the temperature regulating water is transported from the water inlet pipe 51 into the cavity and output from the water outlet pipe 52 , thereby achieving the temperature regulation of the cathode body 14 .

[0061] In the present application, when the cathode body 14 moves downward, the bottom end of the cathode body 14 first contacts the limit plate 42, the spring 43 is compressed, and the telescopic rod 41 is shortened, thereby preventing the bottom end of the cathode body 14 from touching the bottom.

[0062] Specifically, the limiting plate 42 is configured as a long plate, which can achieve the effect of contacting the bottom end of the tubular cathode body 14 .

[0066] Specifically, the slide 61 is inclined at a certain angle to the horizontal plane, and the front side of the slide 61 is higher than the rear side, which can reduce the sliding rod 62 from sliding out of the slide 61 and reduce the falling off of the receiving barrel 63.

The separator 2 can separate the cathode area 12 and the anode area 11. The height adjustment component 24 of the separator 21 can be used to adjust the height of the movable plate 23 according to the amount of raw gallium. When the height adjustment component 24 drives the movable plate 23 to move upward, the multiple groups of connecting holes 22 on the lower side are blocked. At this time, the usable height of the separator 21 becomes higher, and the amount of raw gallium that can be placed increases. On the contrary, the amount of raw gallium that can be placed decreases, the liquid crude gallium at the anode dissolves, and the GaO2 in the electrolyte is dissolved. -After the ions migrate to the cathode for discharge and precipitation, the cathode body 14 is arranged in a tubular shape to increase the surface area and improve the electrolysis efficiency. At this time, the temperature regulating mechanism 5 cools the cathode body 14 to a suitable temperature so that the connected gallium crystallizes on the surface. After the electrolysis is completed, the handle 345 is turned. Under the connection between the rotating plate 344 and the third connecting shaft, the front second bevel gear 342 rotates. Under the meshing action of the second connecting shaft 343 and the teeth, the two sets of first bevel gears 341 rotate accordingly. Under the connection between the two sets of first connecting shafts Under the use, the two groups of first threaded rods 242 rotate accordingly, thereby driving the cathode body 14 to move upward out of the liquid surface. At this time, the temperature of the cathode body 14 is made higher than the melting temperature of the electrolytic gallium through the temperature regulating mechanism 5, and the slide rod 62 is inserted from the front side of the slide 61 and pushed to the rear end. At this time, the receiving cylinder 63 can receive the electrolytic gallium, and the molten electrolytic gallium is transported downward to the receiving mechanism 6, thereby realizing the separation operation of electrolytic gallium and raw material gallium, reducing the mixing phenomenon of the two, and improving the purity of electrolytic gallium.
