Description
Technical Field
[0001] The utility model relates to the technical field of dust removal and explosion prevention, in particular to a dust collector explosion-proof device. Background Art
[0002] The explosion-proof valve of the dust collector plays a role in preventing secondary explosions of dust, such as dust from planers in furniture factories, metal dust from grinding and polishing, and secondary explosions of hardware dust in foundries. It can effectively protect the development of indoor workshop industries and increase the potential danger of dust explosions. In actual production, if explosion-proof panels are used to vent explosions and explosion isolation is not done well, the flames and pressure waves generated by the explosion will be transmitted to other connected equipment through the connected pipes, causing secondary or even more powerful explosions. Explosion-proof technology can prevent the explosion from spreading from the initial location to other process equipment, avoid the occurrence of "secondary" explosions or system explosion accidents, and thus reduce explosion disasters.
[0003] Pipeline explosion-proof valves are normally used in dust removal pipelines. They are simple, economical and reliable explosion-proof products. They are mainly used to prevent the flames and shock waves generated by the explosion inside the equipment from being transmitted to the upstream pipelines and equipment. However, traditional explosion-proof valves only have a blocking effect and cannot handle the high-temperature flue gas in the pipeline, resulting in the flue gas in the dust removal pipe not being able to be dispersed in time, posing a safety hazard.
