[0002] The bag dust collector is a dust removal device that is efficient, reliable, economical, has a large processing capacity and is easy to use. The filter bag is the core dust removal component of the bag dust collector. During use, the filter function of the bag is used to filter the dust, so that the dust adheres to the outside of the bag, and the heavy dust particles will settle due to their own weight. Every time it works for a period of time, the pulse dust blowing system automatically starts, using compressed air to blow from the inside of the bag to the outside, so that the dust particles fall off and extend the service life of the filter bag.

[0003] Although the filter bag can be cleaned by the pulse soot blowing system, it is still a consumable material and needs to be replaced regularly. The filter bag is generally connected to the flower plate through the bag cage. When it is repaired and replaced, it needs to be operated individually and installed on site, which is time-consuming and labor-intensive. Utility Model Content
