    The invention relates to non-ferrous metallurgy and can be used in the refining of aluminum, magnesium, copper, zinc, tin, lead and their alloys.
    The purpose of the invention is to increase the productivity of the device, '
    The drawing shows the proposed device.
    The device comprises a bath 1 with inlet 2, exhaust 3 and two refining 4 and 5 cells, with three transverse partitions 6-8 and two parallel partitions 9 and 10. On the lid 11 of the bath 1 in the center of each refining cell 4 and 5 there is a device 12 for gas distribution with a drive at the upper end of the vertical shaft and a rotor at its lower end. The longitudinal partition 9 is blind, the partitions 6, 7 and 10 do not reach the bottom 13 of the bath, and the upper edge of the partitions 8 and 6 is below the level of the drain threshold 14. In the first refining cell 4 opposite the partition 7 there is an additional partition 15, the upper edge of which is , below threshold level 14, Longitudinal partitions 9 and 10 divide inlet 2 and outlet 3 cells into metal inlet and outlet compartments and throttle compartments. In the throttle compartment, the longitudinal partition 9 is solid and the transverse partition-6 is fixed so that its upper edge 16 is below the threshold level 14, and the lower edge 17 is located at a distance from the bottom 13 of the bathtub.
    In the dividing compartment of the cell 3, the longitudinal partition 10 is made with a lower edge 18 located at a distance from the bottom 13. The flow of the melt is shown in the drawing by arrows.
    The device operates as follows.
    The molten metal enters the bath through the inlet compartment of the cell 2, goes down under the partition 6 and then in the cell 4, interacting with the gas supplied from the distribution device 12, is refined. The throttle returns to the cell compartment 2 by flowing over the edge 16 of the partition 6. The melt from the cell 4, bypassing the walls 15 and 7, enters the second refining cell 5, where it interacts with the gas again and enters the exhaust compartment of the outlet cell 3 over the partition 8. The throttle is removed in this cell, 5 and the melt cleaned from non-metallic impurities under the lower edge 18 of the partition 10 is discharged.
    An example. Two refining cells with a width of 584 mm, a length of 737 mm and a melt depth of 737 mm are equipped with gas distribution devices 12 with rotors with a diameter of 190.5 mm, carrying eight blades located15 from the bottom of the bathtub at a distance of 125 mm. The inlet and outlet compartments have a length of 279 mm and a width of 102 mm. Partitions 6,7 and 10 have a height of 152 mm, the distance between partitions 7 and 15
    76 mm. In the model of the device, when 0.16 m E / min of gas (hydrogen) and a rotor speed of 550 rpm are supplied, the productivity is 54.5 t / h for aluminum.
