Title:
SMOKE AND DUST TREATMENT APPARATUS FOR WELDING
Document Type and Number:
WIPO Patent Application WO/2020/087939
Kind Code:
A1
Abstract:
A smoke and dust treatment apparatus for welding, said apparatus comprising a polishing and dust extraction module and a smoke and dust purification module. The polishing and dust extraction module comprises a double-layer dust extraction cover (3), a protective cover (2), an industrial brush (4), a first air guide portion, a second air guide portion (24) and a drive motor (22), the drive motor (22) driving the industrial brush (4) to rotate at high speed to perform polishing. During welding and polishing, a mechanical arm (6) drives the double-layer dust extraction cover (3), and a suction hole (20) of the double-layer dust extraction cover (3) and a suction guide hole (19) on the industrial brush (4) simultaneously take in toxic gas and debris such as iron filings. The smoke and dust purification module comprises a residue collection chamber (13), a smoke purification chamber (15), an exhaust fan (14) and an gas discharge passage (17), the residue collection chamber (13) collecting the debris such as iron filings produced during the welding and polishing, a substance inside the smoke purification chamber (15) performing physical filtration to convert the debris into non-toxic gas, which is then discharged via the gas discharge passage. The smoke and dust treatment apparatus integrates the three processes of polishing, welding and dust extraction during a welding procedure, thereby implementing apparatus intensification, and utilises the protective cover and air guide holes to enhance a negative pressure dust extraction effect. The residue collection chamber and the smoke purification chamber recover the residue, and further purify toxic gas in smoke.
