Since most of the packaging machines are powders and granules, it is inevitable that there will be dust. Particles are fine, and those ultra-fine powder materials (such as milk powder, toner, etc.) are particularly dusty.
At this time, due to a large amount of material dust floating in the air, most of those flammable and explosive dusts contain chemical elements such as H, C, N, S, etc. When they oxidize in the air, they will generate heat and explode. Dangerous, especially when aluminum powder explodes in a carbon dioxide atmosphere.
The difficulty of material dust explosion is related to its own nature and environment, and the reasons for the explosion are not the same. Some materials are easy to conduct electricity, and some materials are non-conductive but will be static due to machine operation and air friction. .
Therefore, it is very necessary to do a good job of explosion-proof measures for packaging machines. Here are a few points:
1. Ensure that the surrounding air is stable and avoid exposure to oil mist. Inflammable and explosive environments such as gas;
2. By using dust-proof means such as a dust-free feeding station and ensuring the airtightness of the packaging machine and conveying system to completely eliminate dust, the explosion can be avoided with a high probability;
3. Use explosion-proof motors (explosion-proof, increased safety, positive pressure, non-sparking and dust explosion-proof, etc.) and explosion-proof touch screens and other explosion-proof equipment to assemble and manufacture packaging machines.
