The heating unit 3 can heat the lubricating oil material inside the tank 1, making it heated evenly.
[0028] Heating tubes 302 are spirally distributed on the inner wall of the heating shell 301, and the output end of the power supply assembly 304 is fixedly connected to the heating tubes 302. The spiral heating tubes 302 ensure that the lubricating oil material inside the tank 1 is heated evenly.

[0030] The circulation pipes 402 are arranged in an S-shape on the inner wall of the condenser 401 and are made of copper. The S-shaped circulation pipes 402 cool the steam and turn it into liquid.
[0031] Multiple filter plates are fixedly connected to the inner wall of the air outlet 102, and the pore size of the filter plates gradually decreases from bottom to top. Impurities in the steam can be absorbed and filtered through the air outlet 102.

During the stirring process, water can be injected into the heating shell 301, and the power supply component 304 is started to heat the water through the heating tube 302. The heat generated by heating is transferred to the tank 1, thereby raising the temperature of the lubricating oil raw material in the tank 1 and promoting evaporation. The steam generated during the heating process enters the condenser 401 through the outlet 102 and the circulation pipe 402. The condenser 401 cools the steam in the circulation pipe 402 and forms a pure liquid, which is then collected through the collection tank 403. The purified lubricating oil can be discharged through the outlet at the bottom of the tank 1.
