How to Protect Bai Gang Charging Funnel with Nitrogen?

1. Before starting nitrogen protection, it is necessary to empty the air in the funnel and replace it with nitrogen. Nitrogen will enter from the top entrance and push out the air in the funnel until the whole funnel is filled with nitrogen.

2. Secondly, once the funnel is filled with nitrogen, it is necessary to maintain a certain nitrogen pressure to prevent air from entering. This can be achieved by installing a pressure regulator at the nitrogen inlet to adjust the nitrogen pressure to a suitable value.

3. Finally, in the process of feeding, nitrogen should be continuously supplied to prevent the materials from being oxidized. This can be achieved by keeping the nitrogen valve open during the feeding process. When the material enters the hopper, nitrogen will enter the next process with the material, thus protecting the material from oxidation.
