Description

Technical Field

[0001] The present application relates to the technical field of aluminum liquid refining equipment, and in particular to a vertical furnace refining machine that is easy to maintain. Background Art

[0002] The furnace refining machine is also called the aluminum liquid refining degassing machine. The principle is that the rotating graphite rotor will break the inert gas (argon or nitrogen) blown into the aluminum liquid into a large number of dispersed bubbles and disperse them in the aluminum liquid; the bubbles in the aluminum liquid absorb hydrogen and oxidized slag in the aluminum liquid by the gas partial pressure difference and surface adsorption principle, and are taken out of the aluminum liquid surface as the bubbles rise, so that the aluminum liquid can be purified; because the bubbles are small and dispersed, they are evenly mixed with the rotating molten metal, and slowly float up in a spiral shape as they rotate. When they come into contact with the aluminum liquid, they will not form a continuous straight-line rising airflow, thereby significantly improving the purification effect. Argon and nitrogen can both be used as gases for degassing and deslagging aluminum liquid.

[0003] In the related art, most of the aluminum liquid is refined by using a fixed vertical furnace refining machine. Figure 1 The vertical furnace refining machine includes a refining mechanism 110, a mounting frame 100 and a protective plate 120, wherein the refining mechanism 110 is fixedly installed on the mounting frame 100 in an inclined manner, and a refining rotor 111 is rotatably arranged on the refining mechanism 110; the protective plate 120 is also installed on the mounting frame 100 to protect the refining mechanism 110. The refining rotor 111 can be inserted into the aluminum liquid through the drive of the refining mechanism 110 to complete the refining and degassing operation.

[0004] Since the refining mechanism 110 is fixedly installed on the mounting frame 100 at an angle, when maintenance is needed, the staff needs to go up to perform the operation, which is inconvenient and has potential safety hazards. Utility Model Content
