<p>A device and method for removing impurities in aluminum melt. The device comprises an upper furnace body, a lower furnace body, an intermediate partition plate, a crucible, heating elements and a charging opening. The intermediate partition plate is mounted between the upper furnace body and the lower furnace body. The upper furnace body, a mixing chamber and the heating element are above the intermediate partition plate. The crucible is amounted in the lower furnace body. The heating element is provided around the lower furnace body. The lower furnace body is provided with the charging opening and a pipeline. The upper furnace body is provided with an inlet valve and an exhaust valve. The mixing chamber and the crucible are connected by a jet pipe passing through the intermediate partition plate. A ceramic seal pad is used for sealing between the mixing chamber and the jet pipe. During use, the aluminum melt and a liquid flux are placed in the crucible, the liquid flux covers the aluminum melt, the pressure of the lower furnace body is increased, the aluminum melt first stably enters the mixing chamber along the jet pipe, then the liquid flux enters the mixing chamber in a manner of confined jet flow and is uniformly mixed with the aluminum melt, last the pressure of the lower furnace body is unloaded, so that the mixed liquid falls back into the crucible, and this operation may be repeated for multiple times. For the device and the method, the impurity removal is quick, the efficiency is high and the process is closed, so there is no environmental pollution, and the aluminum melt after the impurity removal may be directly cast.</p> |
