Mobile automatically cleaning welding dust collector/eliminator
Separation: dust laden fume are sucked into the extractor by the suction force induced by fan’s working, with deflector fume’s flowing speed is slowed, big practical and sparks are cooled, separated and then settle into dust collector. Fine fume and dust enter into filter compartment to be filtered by the filter cartridge. The filter cartridge is coated with PTFE film which is covered with uniform pores, it has good air permeability, and dusts are filtered out on its surface. Purified air enters into the filter cartridge’s interior and then discharged into workshop directly or out of the workshop through pipe line.
Cleaning: when dusts accumulate continuously on filter cartridge’s surface, the pressure difference between its interior and exterior will increase steadily, when the pressure difference reach pre-set value(1500Pa), the pulse valve will open, dry, oil-free compressed air rush into the reverse blow cleaning system. The system rotate and high pressure air stream jet at the interior of filter cartridge, blow off dusts accumulated on the filter cartridge’s surface, dusts fall into dust collector under gravity, thus the whole cartridge’s surface is cleaned.
This extractor can be automatically cleaned and manually cleaned, automatically cleaning is as following:
1. When air pressure difference reach 1500Pa between the interior and exterior of the filter cartridge, the system will implement interval rotation pulse blow cleaning.
2. When the fan stops working, the system will implement rotation pulse blow cleaning for three times.
Smart mobile welding fume extractor has two directional and two rotary polyurethane casters with brake device for easy moving and stationing. It is suitable for the purification of fume and dust generated in all kinds of welding, grinding and other places as well as for collecting rare metal particles and precious material.
Suction arm can be rotated by 360 °and can reach the position flexibly and easily by pulling the handle on the hood and position in the absence of external force. Depending on needs, 3m or 4m flexible suction arms are available. Suction arm uses high temperature resistant, flame retardant and wearable composite material, it will not crack after burning through by spark and has a longer usage life. The diameter of suction arm is 160mm.
The fume comes from the processing will be sucked into the extractor through the hood, first the fume passes the 1st layer spark intercept steel mesh which will separate and intercept the spark initially. And the fume enters into second layer namely filter preventer plate to avoid residual sparks enter into main filter layer directly through ramifying the fume. At last the fume enters the third layer namely the main filter cartridge for ultimate purification.The filtration efficiency can reach 99.9%.
As the filtering precision of the main filter cartridge reach the indoor emission standards, after filtration clean air can be directly discharged indoor through the air vent in the back of the extractor. The filter inside makes use of full automatically rotating blowing (pulse nuzzle cleaning) system for cleaning ash while connecting the compressed air source, it makes the surface of filter more clean and tidy. So the dust collector is always keeping the constant air flow.
1. CE certification and EMC test report is approvable.
2. Application for large fume occasion. For example, GSAW (CO2),MMA,,Laser welding, floating dust and so on.
3. Large air flow, automatically cleaning, maintaining easy, two units arms to be more competitive price.
4. Good parts make sure the qualilty, for example, Schneider,CHNT electrics, Siemens PLC and montoring screen, USA gas-pressure switch, Japan Toray filtering material, AKZO Nobel spraying powder etc.
