Description

Technical Field

[0001] This utility model relates to the field of metal purification technology, specifically a rare earth metal dust collection device. Background Technology

[0002] Rare earth metals, as strategically critical materials, are widely used in high-tech fields such as new energy, electronic information, and aerospace. With the increasing demands for material purity from downstream industries, zone melting has become one of the core processes for rare earth metal purification due to its efficient ability to separate impurities. However, after the rare earth metals volatilize at high temperatures, the temperature gradient-induced condensation effect causes loose metal dust to form on the surface of the quartz boat, which then falls back into the boat. When the material is removed from the furnace, it needs to be wiped with a lint-free cloth or blown off the loose metal dust with an air gun. Wiping with a lint-free cloth can contaminate the material; when blowing off with an air gun, the instantaneous airflow causes the metal dust to scatter, making it difficult to capture.

A vacuum cleaner 6, communicating with the interior of the operation box 1, is installed on the third side wall of the operation box 1. Multiple dust discharge holes 18 are opened on the side wall of the operation box 1. The vacuum cleaner 6 is connected to the operation box 1 via a flexible steel wire hose 5, which consists of a main pipe and multiple branch pipes. The branch pipes are connected to the multiple dust discharge holes 18 one-to-one, and the end of the main pipe is connected to the negative pressure inlet of the vacuum cleaner 6. A blowing assembly is installed inside the operation box 1. The air inlet of the blowing assembly is connected to an external air source 8 via an air pipe 7. The air pipe 7 is a PU air pipe; the air source 8 is a nitrogen cylinder.

[0020] Furthermore, the purging assembly includes a tube head 9 that penetrates the operation box 1. The end of the tube head inside the operation box 1 is connected to a telescopic spring tube 10, and the other end of the telescopic spring tube 10 is connected to a purging gun head 11. The purging gun head 11 is an air pump gun, and the end of the tube head outside the operation box 1 is connected to an air pipe 7. This facilitates the use of the purging gun head 11 to purge the material inside the operation box 1 from all directions.

[0021] Furthermore, the sleeve assembly includes a fixing ring 14 fixed to the inner wall of the operating box 1, and a sleeve 15 is fitted on the fixing ring 14.
