The invention discloses a quick homogenization stirrer for a petroleum auxiliary additive. The stirrer comprises a mixing barrel. The cross-section of the mixing barrel is rectangular. The upper end of the mixing barrel is provided with a feeding inlet. The side end of the mixing barrel is provided with a first motor and a second motor. The first motor is connected to a first rotating shaft located in the mixing barrel. The second motor is connected to a second rotating shaft located in the mixing barrel. The first rotating shaft is provided with a first stirring blade in a spiral shape. The second rotating shaft is provided with a second stirring blade in a spiral shape. The spiral directions of the first stirring blade and the second stirring blade are opposite. The lower end surface ofthe mixing barrel is provided with a funnel-shaped discharge port. The funnel-shaped discharge port and the lower end of the second rotation shaft form a discharge cavity for rapid material discharge.The first rotating shaft, the second rotating shaft, the first stirring blade and the second stirring blade are arranged in the mixing barrel, and the first stirring blade and the second stirring blade are in a continuous spiral shape so that the device has good effects of uniformly stirring petroleum raw and auxiliary materials.
