[0002] Waste oil refers to the oil that is contaminated by physical or chemical impurities after being used, which is refined from crude oil or synthesized, and waste oil pretreatment refers to the process of removing impurities and pollutants in waste oil to purify oil quality through a series of methods.

[0003] According to the search, the Chinese patent with the publication number CN218740757U discloses a waste oil pretreatment filtering device. The waste oil is poured into the inside of the sedimentation tank through the feeding pipe, and then the adsorbent is poured into the inside of the sedimentation tank from the medicament pouring pipe. At this time, the first motor is turned on, and the rotation of the output shaft of the first motor drives the rotating rod to rotate, thereby driving the stirring blades on the outer surface of the rotating rod to rotate, so that the adsorbent and the waste oil are fully stirred. After a period of standing, the impurities in the waste oil are adsorbed on the surface of the adsorbent. Further, the valve is opened, and the waste oil is discharged into the inside of the filtering barrel through the conveying pipe. At this time, a large amount of waste oil is poured into the inside of the annular filter screen, and the impurities adsorbed by the adsorbent are filtered out through the annular filter screen. The filtered oil flows to the bottom of the filtering barrel, thereby further achieving the effect of filtering waste oil.
