The purification main pipe of the welding air purifier is consistent with the model parameters of the vacuum cleaner and the blower. The materials are carbon pipe and galvanized pipe. The main pipe is configured on the site and the wall of the site, branched to each station, and the small workpiece is welded with the suction arm That is, the suction arm can be moved in any direction, which is very convenient. When welding large workpieces, it is necessary to install the Dust hood pulse filter device and the bag filter device. The working principle is the same; after the dusty gas enters the filter hopper, the air flow end surface suddenly increases. Large, some coarse dust particles settle under the action of gravity and inertia. After the dust particles enter the filter chamber, through the combined effects of Brown diffusion and filtration, the dust particles are deposited on the surface of the filter, and the purified gas entering the filter is exhausted. The pipe is exhausted by a fan.

The resistance of the welding air purifier increases with the increase of the thickness of the dust layer on the surface of the filter material. After the resistance reaches a certain value, the automatic dust removal system will be pneumatic. When the dust is removed, the pulse controller controls the opening of the pulse valve, and when the pulse valve is opened , The compressed air in the air bag sprays high-speed, high-pressure jet airflow through the small hole of the blowpipe through the pulse valve, forming a guided airflow equivalent to 1~2 times the volume of the jet airflow, and enters the bag and filter cartridge of the vacuum cleaner at the same time. The instantaneous positive pressure causes the swelling and fretting of the dust deposited on the filter material to fall off, and the dust in the ash hopper.

Welding air purifier runs smoothly, with low noise, and low maintenance costs. The small design not only takes up a small space, but is also movable without affecting the normal operation of other equipment; stable replacement of consumables, fast and convenient after-sales, and worry-free after-sales.
