In addition, the top of the collecting box 141 is fastened with a cover plate 160, one end of the cover plate 160 is provided with a plurality of cover plate holes 161, the cover plate holes 161 are matched with the water flowing pipe 154, the cover plate holes 161 are in insertion fit with the water flowing pipe 154, the other end of the cover plate 160 is provided with a mounting groove 162, a baffle 163 is fastened in the mounting groove 162, the baffle 163 is preferably made of transparent glass, so that the mineral oil capacity in the collecting box 141 can be observed conveniently, and the cover plate 160 can seal the collecting box 141, so that the mineral oil in the collecting box 141 can be prevented from contacting with dust.

Besides, the fixing block 211 has one side provided with a threaded counter bore 230, the threaded counter bore 230 is internally threaded with a threaded rod 231, the other end of the threaded rod 231 is fixedly connected with a rotating ring 232, the rotating ring 232 is matched with the second fixing shaft 214, the second fixing shaft 214 is rotatably connected with the rotating ring 232, and the threaded connection can enable the second fixing shaft 214 to be rapidly installed and detached so as to improve the maintenance efficiency in the later period.

When the distillation device for waste mineral oil based on buoyancy control automatic feeding is used specifically, waste mineral oil is poured into the distillation barrel 110, the heating wire 113 is connected to enable the distillation barrel 110 to work, the heating wire 113 works to transfer heat to the distillation barrel 110, the distillation barrel 110 transfers heat to the waste mineral oil, the waste mineral oil is heated and boiled to generate steam, the steam is discharged through the drain pipe 123 and is converted into liquid through cooling, when the waste mineral oil in the distillation barrel 110 is reduced, the connecting ball 217 moves downwards, the connecting ball 217 drives the connecting column 216, the connecting column 216 drives the rectangular plate 215, one end of the rectangular plate 215 moves downwards through the second fixed shaft 214 to enable the other end of the rectangular plate 215 to move upwards, the rectangular plate 215 drives the rotating block 219, the rotating block 219 drives the supporting plate 226, the supporting plate 226 moves towards the water inlet pipe 221 through the shaft hole 228, the supporting column 224 is driven by the supporting column 224, the spherical column 224 drives the, the round ball 223 moves to open the blocked opening of the water inlet pipe 221, the waste mineral oil flows into the distillation barrel 110 through the opened opening, and when the mineral oil in the distillation barrel 110 is enough, the waste mineral oil in the distillation mechanism 100 drives the connecting ball 217 to rise, so that the round ball 223 moves to block the opening.
