Welding fume treating device

Abstract

The invention discloses a welding fume treating device which comprises a box body, wherein a fan is arranged at the upper end of the right side in the box body, the upper end of the fan is fixedly connected with an air inlet pipe, the lower end of the fan is fixedly connected with a first guiding pipe, a sedimentation box is welded to the lower end of the right side in the box body, a first sealing plate is arranged at the top of the sedimentation box, a second guiding pipe is arranged at the left end of the first sealing plate, the other end of the second guiding pipe is communicated with anoxidization chamber, a second sealing plate is arranged at the top of the oxidization chamber, a third guiding pipe is arranged at the bottom of the oxidization chamber, the other end of the third guiding pipe is communicated with a drying chamber, a third sealing plate is arranged at the top of the drying chamber, an air outlet pipe is arranged on the left side of the third sealing plate, and universal wheels are arranged at the bottom of the box body. The welding fume treating device has the advantages of convenience in moving and ability in fully removing metallic oxide particles, metal ions and poisonous and harmful gas in the fume.

Description

technical field [0001] The invention belongs to the technical field of welding, and in particular relates to a welding fume treatment device. Background technique [0002] The dust in the welding fume is a very complex substance. More than 20 elements have been found in the dust, among which Fe, Ca, Na, etc. are the most abundant, followed by Si, Al, Mn, Ti, Cu Wait. The main harmful substances in welding fume are Fe2O3, SiO2, HF, etc. Among them, Fe2O3 is the most abundant, accounting for 35.56% of the total fume, followed by SiO2, which accounts for 10-20%. The main components of toxic and harmful gases in welding fume are CO, CO2, O3, NOX, CH4, etc., among which CO accounts for the largest proportion. [0003] During metal welding, a large amount of smoke and dust is suspended in the working environment. The smoke and dust are inhaled into the lungs of the human body, which will seriously affect the health of the body. In severe cases, it can also cause diseases such as...

Problems solved by technology

[0003] During metal welding, a large amount of smoke and dust is suspended in the working environment. The smoke and dust are inhaled into the lungs of the human body, which will seriously affect the health of the body. In severe cases, it can also cause diseases such as chronic manganese poisoning and welder pneumoconiosis, which is extremely harmful to operators.
