Description

Technical Field

[0001] This utility model relates to the field of metal refining technology, specifically to a pyrometallurgical refining apparatus with a flue gas filtration mechanism. Background Technology

[0002] Pyrometallurgical refining refers to the refining process of removing impurities from crude metals by various methods under conditions of high-temperature melting. After the crude metal is heated and melted, the temperature is controlled during the cooling process of the melt. Due to the differences in solubility and specific gravity between impurities and metals, stratification occurs, thereby achieving the purpose of separating impurities.

[0003] Pyrometallurgical refining equipment generates fumes during the metal refining process. Most refining equipment directly discharges the fumes, which greatly affects air safety. When the refining equipment is connected to a filtration mechanism to filter the fumes, some filtration mechanisms become covered with soot after filtering fumes for a long time. If this soot is not cleaned in time, it will affect the normal filtration efficiency.

[0004] There is an urgent need for a pyrometallurgical refining apparatus with a flue gas filtration mechanism to address the technical deficiencies mentioned above. Utility Model Content

The flue gas filter plate and the flue gas filter screen inside the filter box can filter the flue gas. The filtered flue gas can be discharged from the exhaust port. Then the servo motor drives the cleaning brush shaft to rotate. The brush on the outside of the cleaning brush shaft can clean the flue gas filter plate and the flue gas filter screen so that the soot on the surface falls into the interior of the dust collection box. Then the dust collection box can be removed for cleaning. This structure realizes the function of easy flue gas filtration and cleaning.

[0017] (3) By setting up a collection screen, a sealing door and a cleaning port, the metal material to be refined is put into the interior of the refining furnace from the feed port. The metal material first accumulates on the collection screen, and then the spray gun refines it at high temperature. During the refining process, the collection screen can collect the slag.

After processing, the molten metal is discharged from the discharge port. The slag on the collection screen can be cleaned by opening the sealing door. This structure realizes the function of facilitating the collection and cleaning of slag. Attached Figure Description
