Description

Technical Field

[0001] This utility model relates to the technical field of aluminum melting furnace devices, specifically to a side well double-chamber melting furnace for aluminum processing. Background Technology

[0002] Aluminum is a silvery-white, lightweight metal with ductility. It is commonly produced in the form of rods, sheets, foils, powders, strips, and wires. In humid air, it can form an oxide film that prevents metal corrosion. The aluminum melting furnace is a new type of high-efficiency and energy-saving furnace developed based on the aluminum smelting process. It can well meet the requirements of the aluminum smelting process.

[0003] Existing double-chamber aluminum melting furnaces employ a left-right double-chamber layout, achieving aluminum molten metal separation through interconnecting holes. Since the furnace's internal volume is fixed, strict control of the aluminum molten metal level is necessary to ensure effective separation. However, some aluminum molten metal residue still remains. Because aluminum has a relatively low melting point compared to other metals, other metals, such as iron, remain in the melting chamber after the aluminum melts and separates, making them difficult to clean and remove. Furthermore, traditional double-chamber aluminum melting furnaces use gas heating, which, while reducing pollution, suffers from slow heating speeds, difficulty in temperature control, and low operating efficiency. Further improvements are warranted. Utility Model Content

The molten aluminum leaks into the secondary heating chamber 3 for further heating and smelting. The iron impurities remain on the top surface of the filter plate 6. This device achieves rapid melting and separation through the heating coil 5, with high working efficiency and good separation effect. At the same time, after the separation is completed, the first electric cylinder 17 extends, pushing the electromagnet 19 down to attract the iron impurities.

[0029] In one embodiment, the filter plate 6 has densely and uniformly formed filter holes on its surface, and the diameter of the filter holes is smaller than the minimum size of iron impurities, which facilitates the separation of molten aluminum and other metal impurities.
