    专利说明:

    The invention relates to non-ferrous metallurgy, in particular to devices for degassing melted aluminum. A device for refining aluminum VIE by blowing gas is known. installed between the nozzles of the height of the chamber 2, the disadvantage of both devices is the low degree of degassing. The purpose of the invention is to increase the degree of degassing. This goal is achieved by the fact that in the device for continuous degassing of molten aluminum, which includes branch pipes for inlet and outlet of the melt and nozzles for introducing wash gas placed in the chamber and located one above another, the side wall of the chamber is made of upper cylindrical and the lower conic-gh parts or the upper and lower cylindrical parts of different diameters, with the nozzles respectively located in the lower, conical part or in the cylindrical lower and in It zone top cylindrical portion. The nozzles for introducing the wash gas are located tengeally with respect to the indicated part of the side wall and in the same direction as the nozzle for the inlet of the melt. When the side wall of the cylindrical conical nozzle is formed, they are located at the spilled level of the conical part 1 2. The diameter of the holes of the nozzles for gas inlet is 0.127 - 1.905 mm. Figure I shows a cylinder-kinokichesky version of the device, side view} in Figure 2 - a cylindrical version with upper and lower parts of different diameters, side view. The device consists of a chamber 1, which has an upper cylindrical part 2 (in FIGS. 1 and 2) and a lower part 3 (conical in FIG. 1 and cylindrical in FIG. 2), the inlet 4 for the melt inlet and the inlet 5 for the discharge of the melt, the nozzle 6 for the introduction of leaching. gas. Gas injection nozzles may be located tengeally with respect to a portion of the side wall and in the same direction as the nozzles for melt inlet. When performing the side wall of the chamber of the cylindrical nozzle are located at different levels of the conical part. Nozzles with a bore diameter of 0.127 - 1.955 mm can be used to inject gas. The device works as follows. Refined molten aluminum through the inlet pipe 4 is supplied to the upper part 2 of the chamber 1. From the upper part the metal is lowered to the lower part of the chamber 1, while the flushing gas supplied through the nozzles 6 barges through the melt and degasses it. The degassed melt is discharged through the nozzle 5. The use of this device allows the degassing of aluminum by 50-55%.
