Welding &grinding industrial dust purifier/extractor/collector with full-automatic cleaning filter cartridge
1. Mobile intelligent 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.
2. 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%.
3. The filter elment of the welding fume extractor is made of imported PTFE membrane filter material of high filtration precision, and the filtration precision reaches 0.1 μm. In accordance with the extractor work intensity and the amount of dust, the usage life of the filter is different.The corresponding indicator on the control panel will light up to indicate different conditions and a power phase sequence indicator, phase absence and short-circuit protection are set inside. It’s equipped with automatic shutdown mechanism when the temperature is too high (optional).
4. On the control panel, it includes:
- Power switch
- Power indicating light
- PLC implementation of filter automatically cleaning
- Fan rotation direction monitor (Inside the control box)
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.
1. CE certification and EMC test report is approvable.
2. It can make explosion-proof type machine for aluminum & aluminum alloy dust.
3. Application for large fume occasion, the force of sucking is large.
4. Large air flow is adjustable through the air flow valve on the suction hood.
5. Automatically cleaning, maintenance easy, filter cartridge service is long.
