Welding smoke filter cylinder dust collector is mainly designed to control a large amount of fine metal particles that are harmful to human bodies suspended in the air during welding.
Working principle of welding smoke filter cylinder dust collector:
After the dust-containing gas enters the dust hopper of the filter drum dust collector, due to the sudden expansion of the air flow section and the action of the air flow distribution plate, a part of the coarse particles in the air flow settle in the ash hopper under the action of dynamic and inertial forces; After the chamber, through the combined effects of Brownian diffusion and sieve filtering, the dust is deposited on the surface of the filter material, and the purified gas enters the clean room and is discharged by the exhaust pipe through the fan.
The resistance of the welding smoke filter cylinder dust collector increases with the thickness of the dust layer on the surface of the filter material. Clean the dust when the resistance reaches a certain specified value. At this time, the PLC program controls the opening and closing of the pulse valve. First, the one-chamber lift valve is closed to cut off the filtered air flow, and then the electromagnetic pulse valve is opened. The expansion deformation produces vibration, and under the action of the reverse air flow, the dust attached to the outer surface of the dust removal filter bag is stripped and falls into the ash hopper. After cleaning, the electromagnetic pulse valve is closed, the poppet valve is opened, and the chamber is restored to the filtering state. The cleaning chambers are carried out in sequence, from the first chamber cleaning to the next cleaning cycle is a cleaning cycle. The falling dust falls into the ash hopper and is discharged through the ash valve.
Features of welding smoke filter cylinder dust collector:
1.High purification efficiency, 99% purification efficiency for dust with a particle size above submicron;
2. The welding smoke filter cylinder dust collector has a small volume and a small footprint, which effectively saves the use space;
3. The welding smoke filter cylinder dust collector is integrated with the fan. According to different dust producing points, the equipment can be flexibly moved to remove dust
4. The welding smoke filter cylinder dust collector has a simple structure, simple maintenance, and low operating cost.
