AI Technical Summary
The existing arc welding room fume extraction device cannot be flexibly adjusted in position, resulting in poor fume adsorption effect. The simple filtration system leads to unsatisfactory purification effect and inconvenient maintenance, affecting work safety and efficiency.
A fume hood with a multi-layer filtration structure and a hinged linkage adjustment system was designed. The adsorption head can be flexibly adjusted by adjusting the linkage in conjunction with the cylinder. The fume is purified by a combination of HEPA filter and activated carbon. The structure is easy to disassemble and install, and the filter material can be easily replaced.
It achieves precise adsorption of smoke sources, improves smoke capture rate and purification effect, reduces occupational disease risk, improves welding precision and production efficiency, and reduces safety hazards.
