Description

Technical Field

[0001] The utility model relates to the technical field of metal iridium purification, in particular to a sealing device for purifying metal iridium from waste slag. Background Art

[0002] Iridium is a metal. In 1803, when British chemist Tennant and French chemist Descoty used aqua regia to dissolve crude platinum, they discovered two new elements - osmium and iridium - from the black powder remaining at the bottom of the vessel. The content of iridium in the earth's crust is one in ten million, and it is often dispersed in various ores in alluvial deposits and placer deposits together with platinum group elements.

[0003] After searching, it was found that the publication number was CN210974836U, and the name was a sealing device for purifying metallic iridium from waste slag. The application raised environmental description issues that were not mentioned in the iridium recovery and purification method with patent number CN85106777. Combined with the prior art, this work is mostly completed through a glove box to meet the sealing requirements in the purification of metallic iridium. At the same time, it was proposed that the use effect of the glove box is not good, and a targeted improvement was made. The application uses a sliding door as a separation means to isolate the cavity of the glove box into two parts, and the purified metallic iridium product and the mixture containing pungent odor are isolated through the two parts, so that the metallic iridium product can be taken out more quickly, which indirectly improves the efficiency of the purification of metallic iridium. The application reduces the leakage of pungent odors.

[0004] However, since the pungent smell has diffused to every corner inside the glove box during the purification process, even if partitions are made, there is still a pungent smell in the partition space for taking out the metal iridium, and there is still a leakage problem when taking it out. Further improvements can be made. At the same time, the pungent smell remaining in the glove box cannot be discharged quickly and promptly, which also affects the next operation. Further improvements can also be made.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
