The utility model discloses a screw type stirring device used for continuous desulfuration of liquid iron; wherein, a screw rod is used for mixing the liquid iron, copper water or aluminium water; a rotating shaft is fixedly connected with the upper end of the screw rod; wherein, the upper end of the rotating shaft is connected with an electric motor by a reduction devices. The rotating shaft is connected with the screw rod by a lower chuck. The utility model is characterized in that the screw type mechanical stirring is realized; the convection speed of the desulfurizer and liquid iron is improved, and the contact time of the desulfurizer and liquid iron is prolonged; the purpose of the desulfurizer dosage saving and cooling reducing is realized, and the desulfuration residue floating on the liquid iron surface is discharged smoothly along the tangent direction.
