The invention discloses a high-efficiency lubricating oil production blending device. The high-efficiency lubricating oil production blending device comprises a stirring box, a blending box and a condensation box, wherein a material inlet is formed in one side of the top of the stirring box, the other side of the top of the stirring box is fixedly connected with a motor, one end of a motor output shaft is fixedly connected with a driving wheel, the outer surface of the driving wheel is connected with the outer surface of a driven wheel in a transmission manner by virtue of a belt, the axis of the driven wheel is sleeved with a rotating shaft, one end of the rotating shaft penetrates through the stirring box and is fixedly connected with one side of the inner wall of the stirring box, the rotating shaft disposed on the outer surface, disposed in of the inner cavity of the stirring box, of the rotating shaft is sleeved with a sleeve plate, and the outer surface of the sleeve plate is fixedly connected with a stirring rods. According to the high-efficiency lubricating oil production blending device, lubricating oil to be processed is arranged into the stirring box by virtue of the material inlet, and the driving wheel, the driven wheel and the rotating shaft are driven by the motor to rotate so as to drive the sleeve plate and the stirring rods to rotate and to stir and scatter the lubricating oil, so that the accumulation of impurities contained in the lubricating oil can be prevented, and the subsequent processing effect is not influenced.
