[0024] Example: Figure 1 As shown, the lubricating oil filter of this embodiment includes a filtering device 1, a dewatering device 2 and an oil collecting tank 3, the filtering device 1 is used to filter impurities in the lubricating oil, the outlet of the filtering device 1 is connected to the inlet of the dewatering device 2 and the inlet of the oil collecting tank 3 through a conveying pipeline, the outlet of the dewatering device 2 is connected to the inlet of the oil collecting tank 3 and the inlet of the dewatering device 2 through a pipeline, a control valve 5 is respectively provided on one end of the two conveying pipelines connected to the outlet of the filtering device 1, the pipeline between the outlet of the dewatering device 2 and its inlet, and the pipeline between the outlet of the dewatering device 2 and the oil collecting tank 3, and an oil moisture meter 4 is respectively provided at the outlet of the filtering device 1 and the outlet of the dewatering device 2.

[0025] The usage process is as follows:

[0026] The lubricating oil to be recovered is sent to the filtering device 1 for filtration to remove metal and non-metallic impurities in the oil. Then, the water content is detected by the oil moisture meter 4 at the outlet. If the water content is higher than the set value, the control valve 5 on the pipeline connected to the dehydration device 2 is opened, and the control valve 5 on the other pipeline is closed, and the oil enters the dehydration device 2 for treatment (if the water content is lower than the set value, it directly enters the oil collecting tank 3 through the pipeline after filtration). At the outlet of the dehydration device 2, the water content is detected by the oil moisture meter 4 again. If it is qualified, it enters the oil collecting tank 3, and the control valve 5 of the pipeline between the outlet and the inlet of the dehydration device 2 is closed. If it is unqualified, the control valve 5 of the pipeline between the outlet and the inlet of the dehydration device 2 is opened, and the control valve 5 of the pipeline between the outlet of the dehydration device 2 and the oil collecting tank 3 is closed, so that the oil flows back to the dehydration device 2 for treatment until the water content meets the standard. On the whole, the structural design is simple and reasonable, and it can flexibly choose whether to remove water according to the oil type. At the same time, it can effectively filter metal impurities and other non-metallic impurities in the lubricating oil.

The inner wall of the feed hopper 14 is provided with a plurality of circles of spaced magnetic convex ridges 16, and the lower end of the side wall of the outer shell 11 is provided with an outlet.

[0028] In the above embodiment, after the lubricating oil enters the filter cartridge 12, the power rotating mechanism 13 drives the filter cartridge 12 to rotate at high speed, generating centrifugal force, so that the oil in the filter cartridge 12 passes through the filter holes on the side wall of the filter cartridge 12 under the action of the centrifugal force and is filtered. At the same time, when the oil enters the feed hopper 14 and flows downward, the metal impurities inside are adsorbed by the passing magnetic convex ridges 16 and the metal impurities are removed in advance. Its structural design is simple and reasonable, and it can effectively remove metal and non-metal impurities.
