When the driving gear 14 rotates, it will drive the crown gear 2 10 and the crown gear 1 7 to rotate at the same time, and the rotation directions of the crown gear 2 10 and the crown gear 1 7 are opposite, thereby making the stirring paddle 1 8 and the stirring paddle 2 12 rotate in opposite directions inside the processing barrel 1, so that the waste mineral oil inside the processing barrel 1 can be cross-stirred, so that various liquids in the waste mineral oil can be evenly mixed.

[0025] The bottom end of the treatment barrel 1 is fixedly connected to a sedimentation barrel 3, and the bottom end of the sedimentation barrel 3 is fixedly connected to a discharge valve 4, wherein heavier materials will be deposited inside the sedimentation barrel 3, facilitating subsequent pretreatment of the waste mineral oil.
