Description

Technical Field

[0001] The utility model belongs to the technical field of nonferrous metal processing, in particular to a nonferrous metal smelting furnace with a built-in regulating device. Background Art

[0002] Nonferrous metals generally refer to metals other than iron and iron alloys, such as copper and other metal materials. In the process of nonferrous metal processing, a smelting furnace is required for heating and melting. According to the patent document entitled "A Nonferrous Metal Smelting Furnace" with the authorization announcement number CN210292797U, the crucible is hinged on the inner wall of the smelting chamber, and a cam driving mechanism is arranged in the smelting chamber. The operating shaft of the cam driving mechanism extends to the outside of the smelting chamber. By operating the operating shaft, the cam can drive the crucible to flip around its hinge axis toward the discharge channel to pour out the molten metal in the crucible. This avoids setting a closing structure on the crucible, avoids blockage, and improves the stability of the smelting furnace. At the same time, due to the use of the cam driving mechanism, there is no need to set other transmission mechanisms on the crucible, so that the structure of the smelting furnace is simplified and the stability is enhanced. However, the following defects still exist:

[0003] When nonferrous metals are placed in a crucible for smelting, the heating coil can only melt the nonferrous metals on the side of the inner cavity of the crucible first, and then melt the nonferrous metals in the middle, thereby affecting the smelting efficiency of the nonferrous metals.
