During the operation of the lubricating oil, impurities and moisture are easily mixed into the lubricating oil, causing the quality of the lubricating oil to deteriorate, which is harmful to the operation of the equipment. If the lubricating oil is replaced as a whole, not only will the cost be high, but the cost of treating the waste oil as hazardous waste will also be very high. Therefore, the lubricating oil is recycled by filtering the oil during normal production.

[0003] In the prior art, since the vacuum tank of the vacuum oil filter is not an absolute vacuum, the lubricating oil may still be oxidized and deteriorated during the filtration process. Summary of the Invention

[0007] The vacuum tank is connected to a coarse filter on the other side. The coarse filter receives oil from the lubricating oil station. After the oil is filtered out of mechanical impurities by the coarse filter, it enters the vacuum tank. The lubricating oil coming out of the vacuum tank is further filtered out of smaller impurities by the fine filter. The qualified lubricating oil is sent to the unit's thin oil station for use through the oil outlet.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0023] In the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to the up, down, left, and right shown in the reference drawings; "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0024] A best embodiment is given below:

[0025] like Figure 1 As shown, the vacuum oil filter combined production device in this embodiment includes a vacuum pump 1, the vacuum pump 1 is connected to the condenser 2, and the condenser 2 is connected to the vacuum tank 3.

[0026] The vacuum tank 3 is connected to a nitrogen tank 5, which receives nitrogen 6 from a nitrogen pipe network;

[0027] The other side of the vacuum tank 3 is connected to a coarse filter 12. The coarse filter 12 receives the oil 11 from the lubricating oil station. After the coarse filter 12 filters out mechanical impurities, it enters the vacuum tank 3. The lubricating oil from the vacuum tank 3 is further filtered out by the fine filter 14 to further filter out smaller impurities. The qualified lubricating oil is sent to the unit's thin oil station for use through the oil outlet 16.

[0028] The unqualified lubricating oil continues to return to the coarse filter 12 through the circulation pipeline 20 and is circulated and filtered to meet the lubricating oil index.

[0029] The condenser 2 is also connected to a water reservoir 4 , and a vacuum automatic control valve 7 is installed on the pipeline between the vacuum tank 3 and the nitrogen tank 5 .

[0030] A float valve 8 is installed within the vacuum tank 3 to control the amount of oil entering the automatic thermostatic electric heater 9. After being heated by the automatic thermostatic electric heater 9, the oil re-enters the vacuum tank 3. The lubricating oil flashes within the vacuum tank 3, then enters the oil pump 13 for pressure increase and enters the fine filter 14. In this embodiment, the fine filter 14 has an oil outlet 16 on the left and a sampling port 15 on the right.

[0031] A circulation pipe 20 is provided between the oil outlet 16 and the coarse filter 12 , a circulation oil inlet valve 17 is provided on the circulation pipe 20 , and an oil pump outlet pressure gauge 18 is provided on the fine filter 14 .

[0032] The coarse filter 12 is connected to an oil inlet pipe 19 . The coarse filter 12 receives oil 11 from a lubricating oil station through the oil inlet pipe 19 . An oil inlet valve 10 is provided on the oil inlet pipe 19 .

[0033] When the vacuum oil filter combined production device of this embodiment is in use, the oil 11 from the lubricating oil station is initially filtered of mechanical impurities by the coarse filter 12, and then the float valve 8 controls the oil inlet amount of the automatic constant temperature electric heater 9 and the oil level of the vacuum tank 3. After the lubricating oil is heated by the automatic constant temperature electric heater 9 and the temperature is raised, it enters the vacuum tank 3. The water contained in the lubricating oil is gasified and evaporated under the vacuum state. The evaporated material is cooled by the condenser 2 and then collected in the water reservoir 4.

[0034] During the flash evaporation process, nitrogen is used to isolate the air, and the lubricating oil after flash evaporation enters the oil pump 13 to increase the pressure. After the flash evaporation, the lubricating oil is further filtered through the fine filter 14 to filter out fine impurities. The sampling port 15 takes samples, and after the test is qualified, it is sent to the lubricating oil station for use through the oil outlet 16. The unqualified lubricating oil returns to the coarse filter 12 through the circulation pipe 20 to continue the circulation flash evaporation filtration to meet the lubricating oil index.

[0035] Nitrogen 6 from the nitrogen network is connected to the inlet of the nitrogen tank 3 through the vacuum automatic control valve 7 and the pipeline to provide isolated nitrogen for the lubricating oil.

[0036] The oil pump outlet pressure gauge 18 displays the pressure at the outlet of the fine filter 14, and determines whether the lubricating oil is taken out from the sampling port 15 or the oil outlet 16.

[0037] The embodiment described above is only one of the preferred specific implementation methods of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
