[0026] In this embodiment: The heating and gasification mechanism 2 includes an outer cylinder 201 disposed above the base 1. Inside the outer cylinder 201, there is a distillation cylinder 2011. A heating component is installed on the outer surface of the distillation cylinder 2011. An oil inlet pipe 204 is installed on the distillation cylinder 2011. A pressure gauge 205 is disposed on one side of the oil inlet pipe 204. A driving motor 206 is arranged on the distillation cylinder 2011. A rotating stirring component is provided at the power end of the driving motor 206. An oil outlet pipe 210 is installed below the distillation cylinder 2011. A vacuum pump 211 is installed on the distillation cylinder 2011. The heating component includes a heating pipe 202 arranged on the outer surface of the distillation cylinder 2011. One end of the heating pipe 202 is provided with a heater 203. The rotating stirring component includes a rotating shaft 207 disposed at the power end of the driving motor 206. A stirring hollow plate 208 is arranged on the outer surface of the rotating shaft 207. A scraping plate 209 is installed on the outer surface of the rotating shaft 207. A temperature controller is arranged on the heater 203. The heating pipes 202 are evenly wound around the outer surface of the distillation cylinder 2011 so that the petroleum inside the distillation cylinder 2011 is heated evenly during stirring. The vacuum pump 211 is used to evacuate the distillation cylinder 2011.

[0027] In this embodiment: The condensation mechanism 3 includes a condensation cylinder 301 disposed on one side of the heating and gasification mechanism 2. An exhaust component is arranged above the condensation cylinder 301. A condensation coil 303 is vertically installed inside the condensation cylinder 301. An air-cooling component is disposed in front of the condensation coil 303. A water tank 306 is arranged at the rear of the condensation cylinder 301. A circulation pump 308 is provided on the water tank 306. A connecting pipe 307 is installed on the circulation pump 308. A circulation pipe 3071 is installed below the water tank 306.

[0028] Working principle: When in use, first inject petroleum into the distillation cylinder 2011 through the inlet oil pipe 204. Start the vacuum pump 211 to evacuate the air in the distillation cylinder 2011 to form a vacuum chamber to accelerate the distillation speed. Start the heater 203 so that the heating pipes 202 uniformly arranged on the outer surface of the distillation cylinder 2011 uniformly heat the distillation cylinder 2011, with high heat conduction efficiency. Start the drive motor 206 to drive the rotation of the rotating shaft 207, the stirring hollow plate 208, and the scraper 209 to accelerate the distillation speed of the petroleum. The scraper 209 rotates along the inner wall of the distillation cylinder 2011 to scrape off the petroleum sticking to the inner wall. The heat generated inside will cause the internal pressure of the distillation cylinder 2011 to change. Monitor the pressure in the tank through the pressure gauge 205. When the pressure reaches the set value, the pressure relief valve 3021 automatically opens, allowing the steam gathered in the exhaust pipe 302 to enter the condensation cylinder 301. Start the power motor 305 to drive the air-cooling fan 304 to blow cold air for cooling. The cooling water in the water tank 306 is injected into the condensation coil 303 through the connecting pipe 307. The condensation coil 303 cools down the steam to make it liquefy and flow into the collection tank 309. Start the water pump 310 to extract the steam water in the collection tank 309 for recycling, which accelerates the distillation efficiency, is not likely to affect the quality of petroleum, and has good condensation effect with the cooperation of air-cooling and water-cooling heat exchange.
