A condenser 3 is connected in series with the middle of the air pipe 14 to condense water vapor. A primary filter 5 is connected in series with the front end of the oil inlet pipe 8. A cylindrical metal mesh is provided inside the primary filter 5. During the flow of oil in the oil inlet pipe 8, the primary filter 5 is used to filter larger solid particles in the impure oil. The end of the oil inlet pipe 8 and the end of the liquid outlet pipe of the filter cartridge 4 are both connected in series with an electromagnetic valve 15. The input end of the electromagnetic valve 15 is electrically connected to the output end of the PLC controller 10 to control the oil to enter the oil inlet pipe 8 and control the filtered oil to be discharged from the liquid outlet pipe of the filter cartridge 4.

[0022] The oil injection mechanism 9 is arranged in the middle of the vacuum cylinder 2. The oil inlet of the oil injection mechanism 9 is provided with an oil inlet pipe 8. The middle of the oil inlet pipe 8 is connected in series with a heating cylinder 11. The interior of the heating cylinder 11 is provided with an electric heating pipe. The input end of the electric heating pipe is electrically connected to the output end of the PLC controller 10. When the oil flows in the oil inlet pipe 8, the electric heating pipe inside the heating cylinder 11 heats the oil to 100 degrees Celsius. The oil injection mechanism 9 includes a nozzle 91 and a guide shell 92. The nozzle 91 is respectively arranged on the outer arc of the vacuum cylinder 2. In the mounting hole in the middle of the surface, the nozzles 91 are distributed in a ring shape with the central axis of the vacuum cylinder 2 as the center. The guide shell 92 is set on the outer arc surface of the vacuum cylinder 2. The nozzles 91 are connected to the inside of the guide shell 92. The oil inlet of the guide shell 92 is provided with an oil inlet pipe 8. The oil injection mechanism 9 also includes a swivel 93 and a guide hole 94. The swivel 93 is rotatably connected to the inside of the guide shell 92. The outer arc surface of the swivel 93 is provided with a guide hole 94.

[0023] The working principle of a vacuum oil filter vehicle provided by the present invention is as follows: when in use, the vacuum pump 12 is started by the PLC controller 10 to evacuate the interior of the vacuum cylinder 2. Under the action of the external atmospheric pressure, the impure oil enters the interior of the guide shell 92 through the oil inlet pipe 8. During the flow of the oil in the oil inlet pipe 8, the primary filter 5 is used to filter the larger solid particles in the impure oil. At the same time, the electric heating tube inside the heating cylinder 11 is used to heat the oil to 100 degrees Celsius. When the oil enters the interior of the guide shell 92, the motor 97 is started, and the output shaft of the motor 97 drives the gear 96 to rotate. The gear 96 is meshed with the outer gear ring 95, so that the outer gear ring 95 drives the rotating ring 93 to rotate. When the guide hole 94 coincides with the nozzle 91, the oil is discharged from the corresponding nozzle 91. The nozzle 91 sprays into the interior of the vacuum cylinder 2, and the moisture in the oil quickly evaporates into water vapor under the vacuum environment. When the guide hole 94 is misaligned with the nozzle 91, the oil is blocked from spraying into the interior of the vacuum cylinder 2. As the rotating ring 93 rotates, the oil is intermittently sprayed through the annularly distributed nozzles 91, so that the oil enters the interior of the vacuum cylinder 2 from multiple angles, providing time for the separation of steam and oil. The water vapor enters the condenser 3 through the air pipe 14 for condensation, and the condensed water flow is directly discharged. The uncondensed water vapor is discharged into the atmosphere by the vacuum pump 12, and the oil pump 7 is started at the same time, so that the oil collected at the lower end of the vacuum cylinder 2 enters the interior of the filter cylinder 4 through the oil pipe 6, and the impurities in the oil are filtered by the filter paper inside the filter cylinder 4, while further absorbing trace water to complete the filtration of the oil.
