A sealing ring distributed along the edge of the barrel cover 4 is fixedly connected at the joint between the barrel cover 4 and the oscillating barrel 3.

A reciprocating rod 12 is slidably connected to the outside of the eccentric shaft 11, and the end of the reciprocating rod 12 away from the rotating wheel 10 is fixedly connected to one end of the oscillating barrel 3.

[0035] One end of the rotating wheel 10 away from the eccentric shaft 11 penetrates through the inside of the support foot 1, and a driven bevel gear 13 is fixedly connected to the end of the rotating wheel 10 away from the eccentric shaft 11, and the driven bevel gear 13 is located inside the support foot 1.

At the same time, a discharge control valve 20 is fixedly connected to the bottom of the discharge port 9 that is not fixedly connected to the electronic control valve 19.

[0039] Embodiment Two:

[0040] On the basis of Embodiment One, its specific working principle is as follows:

[0041] The oscillator for refining gallium metal adds crude gallium metal and cleaning liquid into the inside of the oscillation barrel 3 at the same time. At this time, the barrel cover 4 is closed, so that the sealing ring at the edge of the barrel cover 4 is engaged and connected with the inside of the sealing groove at the edge of the oscillation barrel 3 to seal the inside of the oscillation barrel 3. The stirring rod 5 is rotated by the motor, so that the stirring rod 5 fully mixes the crude gallium metal and the cleaning liquid inside the oscillation barrel 3 to clean the gallium metal. At the same time, hot water is injected into the inside of the heat preservation shell 6 through the water inlet 7, so that the hot water flows along the water channels separated by the partition plate 8 into an S-shaped distribution inside the heat preservation shell 6, and then the hot water flows outside the oscillation barrel 3. The hot water conducts heat into the inside of the oscillation barrel 3, thereby performing water bath heating on the crude gallium metal and the cleaning liquid inside the oscillation barrel 3. Water bath heating can provide a very stable temperature for the gallium metal. At the same time, because water has a very high specific heat capacity, it can transfer heat evenly, making the gallium metal heated evenly, avoiding the problem of local overheating, making the gallium metal stably maintained at a temperature higher than the melting point, preventing the gallium metal from solidifying and forming crystals during the refining process, and improving the mixing efficiency of the crude gallium metal and the cleaning liquid;

[0042] While the crude gallium metal and the cleaning liquid inside the oscillation barrel 3 are being mixed, at this time, the gear 15 is rotated by the motor, so that the gear 15 drives the drive shaft 14 to rotate inside the connecting frame 2. Furthermore, the drive shaft 14 drives the driven bevel gear 13 to rotate through the bevel gear ring. The driven bevel gear 13 will drive the rotating wheel 10 to rotate, so that the rotating wheel 10 drives the eccentric shaft 11 to rotate around the center of the rotating wheel 10. During the rotation of the eccentric shaft 11, the eccentric shaft 11 will slide inside the lower end of the reciprocating rod 12. At the same time, the eccentric shaft 11 will drive the reciprocating rod 12 to rotate around one end of the oscillation barrel 3, so that the oscillation barrel 3 reciprocates between the two support feet 1, oscillating the crude gallium metal and the cleaning liquid inside the oscillation barrel 3 to improve the mixing efficiency of the crude gallium metal and the cleaning liquid;

[0043] After the gallium metal inside the oscillation barrel 3 is cleaned by the cleaning liquid, the rotation of the stirring rod 5 and the reciprocating rod 12 is stopped. Since the density of the crude gallium metal is greater than that of the cleaning liquid, at this time, the crude gallium metal will precipitate at the bottom of the oscillation barrel 3. At this time, the electronic control valve 19 is controlled to open, so that the crude gallium metal enters the guide pipe 16 through the electronic control valve 19 and the connecting pipe 18. At the same time, the extrusion pump 17 is started to drive the crude gallium metal to flow inside the guide pipe 16 until the crude gallium metal enters another oscillation barrel 3. Since the partition plate 8 is made of a corrugated pipe structure, the partition plate 8 itself has good extensibility and elasticity, so that during the oscillation of the oscillation barrel 3, the partition plate 8 will move along with the oscillation barrel 3;

[0044] The cleaning liquid is set as an acid solution, water, and an alkali solution. The three oscillating barrels 3 are evenly distributed. The acid solution, water, and alkali solution are added into the oscillating barrels 3 in sequence. First, the crude gallium metal is cleaned inside the oscillating barrel 3 with the acid solution added, then enters the oscillating barrel 3 with water added inside through the transportation structure for cleaning, and finally enters the oscillating barrel 3 with the alkali solution added inside through the transportation structure for cleaning, completing a complete refining process for the crude gallium metal. The multiple oscillating barrels 3 are connected to each other through the transportation structure to achieve three acid picklings, three alkali washings, one acid treatment, and one alkali treatment in a cycle three times for refining the crude gallium metal. There is no need for manual operation, and only one oscillator needs to run once to meet the requirement of cleaning the crude gallium produced by the gallium production factory throughout the day into refined gallium, saving manpower.
