AI Technical Summary
The existing high-purity carbon powder purification crucibles have uneven airflow distribution, especially the periphery and edges of the crucible, where the effect is poor and the pores are easily blocked, affecting the purification efficiency.
The design combines an airflow distribution ring and an airflow distribution plate. The airflow distribution ring has inclined vertical and horizontal through-holes, which, together with the through-holes on the airflow distribution plate, achieve uniform airflow distribution inside the crucible. The design of the support ring and the cleaning plate facilitates the cleaning of blockages.
It achieves uniform distribution of inert gas inside the crucible, improving purification efficiency. In particular, the airflow disturbance effect on the periphery of the crucible improves heating efficiency and impurity volatilization rate, and is easy to clean.
