Description

Technical Field

[0001] This utility model relates to the field of road construction dust removal, specifically to a road construction filtration and dust removal device that avoids secondary pollution. Background Technology

[0002] The main purpose of dust control during road construction is to reduce dust pollution and protect the environment and worker health. A Chinese patent (authorization announcement number CN 113171657A) discloses a road construction dust control device to avoid secondary pollution. This patented technology, through its suction mechanism, prevents large plastic bags or other objects from entering the device and causing blockages, thus reducing its dust control efficiency. It also extracts dust generated during road construction, reducing airborne dust and effectively preventing construction dust from affecting the visibility of construction workers. Furthermore, it reduces the risk of construction dust affecting the health of pedestrians or construction workers. However, the filter mechanism and dust collection mechanism in this design cannot be easily disassembled and assembled. Additionally, adjusting the angle of the suction mechanism causes the connected hollow filter mechanism to adjust as well, posing a risk of equipment damage. Therefore, those skilled in the art have developed a road construction dust control device to avoid secondary pollution and address the problems mentioned in the background. Utility Model Content
