[0002] Construction projects generate a large amount of dust, which not only pollutes the construction environment but also harms the health of construction workers. Therefore, the construction industry has an urgent need for environmentally friendly dust control equipment. Efficient and stable dust control devices help improve the quality of the construction environment and ensure the smooth progress of construction.

[0003] However, existing environmental dust removal devices for construction projects still have certain shortcomings: In actual work, the amount of dust generated by construction is large and the composition is complex. The dust easily adheres to the filter screen of the dust removal device. Most existing dust removal devices lack an effective automatic cleaning mechanism for the filter screen. Once dust adheres to the filter screen, it will quickly become clogged over time. After the filter screen becomes clogged, its filtration capacity will be greatly reduced, resulting in a significant reduction in dust removal effect and failing to meet the air quality requirements of the construction site. Moreover, in order to ensure the normal operation of the dust removal device, the staff needs to frequently clean the filter screen manually. This not only increases the labor intensity of the staff but also affects the construction progress and reduces work efficiency. Utility Model Content
