The design of the fresh air pipeline 203 ensures that the clean air filtered by the filter bag body 302 can be smoothly discharged out of the system. The detachable connection design not only facilitates the cleaning and maintenance of the assembly, but also improves the flexibility and upgradability of the entire dust removal system. The air filtering assembly 3 is the core part of the dust removal filter bag, which is composed of the bag cage 301 and the filter bag body 302. The bag cage 301 provides a stable support structure for the filter bag body 302, while the filter bag body 302 is responsible for the actual filtering task.
