Description

Technical Field

[0001] The utility model relates to the technical field of nonferrous metal smelting, in particular to a nonferrous metal smelting smoke and dust separation device. Background Art

[0002] Nonferrous metals refer to metals other than ferrous metals such as iron, chromium, manganese, cobalt and nickel, generally referring to metals such as copper, aluminum, lead, zinc and tin. These metals usually have good electrical and thermal conductivity and are widely used in electronics, construction, automobiles and other fields. Nonferrous metals are characterized by light texture, good toughness and easy processing and molding, so they play an important role in industrial production. A large amount of smoke is generated during the smelting process of nonferrous metals, so a nonferrous metal smelting smoke separation device is needed.

[0003] During use, traditional non-ferrous metal smelting smoke dust separation devices usually use filter bags to filter smoke. Traditional non-ferrous metal smelting smoke dust separation devices do not have a cooling mechanism to cool the smoke, and the smoke will directly enter the filter bag for filtration. The filter bag is directly impacted by the high-temperature smoke, which may cause damage or burning of the filter bag, reducing the practicality of the device. Moreover, when separating the smoke, traditional non-ferrous metal smelting smoke dust separation devices usually pass all the smoke into one filter bag. After the filter bag has been used for a period of time, a large amount of dust will adhere to the surface of the filter bag, which will block the filter bag and affect the filtering effect.
