[0002] A dust explosion is a phenomenon in which dust particles suspended in the air fully come into contact with oxygen in the air and react instantaneously under specific conditions, releasing a large amount of heat, thereby generating high temperature and high pressure. Any dust explosion must have the following three conditions: an ignition source, combustible fine dust, and dust suspended in the air that reaches the limit range of explosive concentration.

[0003] Although explosion-proof dust collectors can effectively prevent dust explosions, traditional explosion-proof dust collectors allow dust to fall directly into the dust storage box in the discharge barrel, causing dust to fly and leak, which not only harms the health of users but also fails to guarantee the explosion-proof effect.
