Description

Technical Field

[0001] The utility model relates to the technical field of waste rhodium recovery and roasting, in particular to a roasting device for recovering rhodium from waste rhodium catalysts. Background Art

[0002] Rhodium is a silvery-white, hard metal with the element symbol Rh. It belongs to the platinum group and has the property of high reflectivity. Due to the limited reserves of mineral resources, production difficulties and low output, many industrially developed countries have turned their attention to the recycling of precious metal resources and recycling them as secondary resources, which can not only directly obtain certain economic benefits, but also improve the utilization rate of resources and reduce the environmental problems caused by catalysts.

[0003] When waste rhodium is roasted for a long time, the temperature of the roasting furnace will gradually rise. At present, when the roasting is completed, most of the roasted rhodium is taken out manually. The high temperature will cause burns, thereby reducing safety issues. Utility Model Content
