Device and method for preparing pure metal through segregation and purification

The invention discloses a device and method for preparing pure metal through segregation and purification, and solves the problems that a spraying device is inconvenient to use and high in working intensity in the existing aluminum purification process. The segregation furnace is used for segregating and purifying molten aluminum; the crucible is used as a supporting body of the molten aluminum; the stirring device is used for stirring and mixing molten aluminum in the crucible after the crucible is put into the segregation furnace; and the spraying device is used for spraying non-stick aluminum paint to the inner wall of the crucible at the initial stage, and the spraying flow velocity can be adjusted along with the change of the inner diameter of the crucible. Compared with the prior art, the spraying device has the advantages that the flow is automatically adjusted according to the size of the inner wall of the crucible through the spraying device, so that uniform spraying is achieved, the stirring efficie
