Characteristics:
1) small size, small floor area, and can be matched with compact space.
2) equipped with caster and handle, easy to move.
3) equipped with 3-meter flexible suction arm, the suction pipe can be moved 360 degrees at will, and the suction hood can be moved to the appropriate position according to the operation situation, so as to achieve the dust collection effect.
4) the double station products are controlled by frequency converter, and three gears of "high", "medium" and "low" are set internally. The gears are changed according to the actual situation of the working environment, with strong suction, stable performance and low noise.
5) the filtered clean air is evenly and reasonably guided and dispersed from the well-designed air outlet, and the clean room is designed with reasonable noise reduction, which can reduce the noise to.
6) add delay relay control, set the delay time at will, easy to operate, carry out automatic pulse back blowing cleaning for the filter cartridge, so as to extend the service life of the filter cartridge.
7) when the equipment is overloaded, the frequency converter has the alarm function.      
8) the filter element is made of imported nano flame-retardant fiber medium, with large filtering area and high filtering accuracy, which can meet the indoor emission standard.
How it works:
After the fan is started, under the action of negative pressure, the dust containing gas flows through the suction arm and enters the dust remover. First, it impacts the splitter plate to change the direction of air flow. Part of the dust with larger particle size in the air flow settles into the ash hopper under the action of gravity; the dust with smaller particle size enters into the filter chamber. Through the filtering effect of the flame-retardant nano filter cartridge, the dust is deposited on the outer surface of the filter cartridge, and the purified gas The body enters the air purification room and is discharged from the air outlet through noise elimination to complete the filtration process. The resistance of the dust remover increases with the increase of dust accumulation on the surface of the filter cartridge. The relay controls the solenoid valve to work. The compressed air back blowing system carries out pulse dust cleaning. The compressed air enters into the filter cartridge through the nozzle. Under the action of the reverse positive pressure air flow, the filter cartridge produces microseism, which makes the dust deposited on the outer surface of the filter cartridge fall off into the dust collector.
Application occasion:
The mobile welding fume purifier is used in the welding, polishing, cutting, polishing and other processes where dust and dust occur, as well as the recovery of rare metals and precious materials. It can purify many fine metal particles that are harmful to human body and reduce the damage to workers' body. The utility model has the characteristics of high purification power, low noise, flexible operation, small floor area, etc. Suitable for arc welding, carbon dioxide maintenance welding, MAG welding, carbon arc gouging welding, gas fusion cutting, separate welding, etc. Equipment operation is simple and maintenance is simple. The pollution source can be processed by mobile single machine or multi station system.
Structural features:
1. The welding fume purifier is composed of centrifugal fan, high-precision filter element, purifier box, active carbon plate, electric control device and flexible suction arm with dust cover.
2. The welding fume purifier adopts filter cartridge filter, which has large filtering area and low filtering flow rate per unit area, so it has high filtering efficiency.
3. The welding fume purifier adopts the optimized design and the inlet air flow sharing and diversion technology, which solves the problem of uneven air flow in each room which is difficult to avoid in the general bag filter.
4. The air distribution design of the welding fume purifier is reasonable, the resistance loss is small, the shape of the machine is small, the movement is flexible, the operation is simple, and the maintenance is convenient.
5. The filter cartridge is made of imported high-efficiency filter material, with a filter efficiency of. 9%. The service life of the filter cartridge is much longer than that of ordinary filter material under normal service conditions.
6. The uniform air guide plate is used in front of the high-efficiency filter cartridge to greatly extend the service life of the filter cartridge.
7. The suction arm of the welding fume purifier can rotate 360 degrees and move up, down, left and right.
8. The bottom of the welding fume purifier is equipped with four wheels, which are portable and applicable to the field of dust purification with frequent changes of working points
