Problems solved by technology

[0002] Welding is an indispensable technology in modern manufacturing, but the welding process produces a large amount of harmful fumes including metal oxides and some non-metallic oxides. Untreated welding fumes are discharged into the air and cause air pollution. To cause harm to the body, the currently commonly used welding fume processing machines are some large equipment, and the welding fume generated during high-altitude welding cannot be effectively purified, so a simple structure, small size, and high processing efficiency is needed.

Embodiment 1

[0016] A portable welding fume purification device, which consists of: a device housing 1, the front end of the device housing is connected to the end of the suction pipe 2, the front end of the suction pipe is connected to the drainage hood 3, the device housing Coarse filter cotton 4, fine filter cotton 5, blower fan 6, and activated carbon adsorption cotton 7 are installed in sequence in the interior, a settling tank 8 is installed at the bottom of the device housing, and a handle 9 is installed at the top of the device housing. The handle is connected with a strap 10 .

Embodiment 2

[0018] According to the portable welding fume purification device described in Embodiment 1, a hanging ring 11 is installed on the top of the draft hood, a support frame 12 is installed on the bottom of the draft hood, and a flame-proof net is installed at the inner end of the draft hood 13. The suction pipe is a high temperature resistant flexible pipe; the number of the settling tanks is three; the number of the handles is two.

Embodiment 3

[0020] A purification method using the portable welding fume purification device described in Embodiment 1 or 2, the fume generated during the welding process is passed into the device housing through the drainage hood and the suction pipe under the negative pressure of the fan, with The large particles of Mars are blocked by the flame-proof net to protect the suction pipe. The welding smoke passes through the coarse filter cotton, and the particles with larger diameters are caught by the coarse filter cotton. The particles gather under the action of gravity and fall into the sedimentation tank. The escaped small particles collide with the fine filter cotton, are intercepted by the surface of the fine filter cotton, and finally fall into the settling tank. The harmful fume is finally absorbed by the activated carbon adsorption cotton, and the welding fume after adsorption is discharged into the air. This process realizes Multi-stage dust removal and filtration of welding fume, ...

Abstract

The invention relates to a portable welding flue gas purifying device and a purifying method. Currently, equipment for processing welding flue gas is basically large-sized equipment, and the treatment effect of welding flue gas at a high place is not ideal. The purifying device comprises a device shell (1), wherein the front end of the device shell is connected to the tail end of an air suction pipe (2), the front end of the air suction pipe is connected to a drainage cover (3); coarse filtration cotton (4), fine filtration cotton (5), a draught fan (6) and activated carbon adsorption cotton (7) are sequentially mounted in the device shell; a settling groove (8) is formed in the bottom of the device shell, and a handle (9) is mounted on the top of the device shell and is connected with a back strip (10). The portable welding flue gas purifying device is used for purifying flue gas.
