Description
Technical field
The utility model belongs to weldering cigarette processing technology field, and more particularly, the utility model relates to a kind of pair of blower fan weldering cigarette absorption cleaning device.
Background technology
In the fields such as boiler manufacturing, heavy-duty machinery, vehicle manufacture, the manufacture of shipbuilding generating set, all have large-scale welding shop.In these workshops, generally there are tens of, up to a hundred electric welding machines or several large-scale automatic welding devices, when these welding machines are worked simultaneously, in workshop, weld fumes content is very high, is seriously polluting air, and harm welding personnel and around personnel's is healthy.The welding method that produces weldering cigarette is mainly that manual metal-arc welding connects and gas shielded welding.In manual metal-arc welding connects, the main component of lime-titania type acidic electrode and low hydrogen type flue dust that basic electrode produces is Fe
3o
4, MnO
2, SiO
2and Fe
2o
3, also have a certain amount of other chemical composition, as MgO, CaO, TiO
2, Na
2o, CaF
2, NaF etc.Pernicious gas and the material of in gas shielded welding, discharging mainly contain: NO
x, CO, O
3, fluoride and halide etc.In modern industry field, the welding of metal material is one of most basic structural member manufacturing procedure.Yet in solder technology develop rapidly, the harm that weld fumes brings environment and welder but not yet causes enough attention.In welding process, produce a large amount of welding fumes, pollute operating environment, the in the situation that of improper ventilation, dust concentration exceeds national standard several times conventionally, can cause the multiple occupational hazards such as electric welder pneumoconiosis, manganese poisoning, respiratory inflammation, nervous breakdown.
At present, the method that butt welding cigarette carries out collection and treatment mainly contains two kinds: a kind of is to carry out whole exhausting in the weld job region of workpiece, and smog is carried out to collection and treatment, although the method is simple to operate, exhausting area is larger, therefore whole exhausting amount is large, energy consumption is high, and smoke abatement effect is undesirable; Another kind is to adopt point-to-point mode, and the weldering cigarette producing for single pad carries out separately collection and treatment with a less suction opeing, and the exhausting amount that the method requires is little, has and uses the advantages such as flexible, convenient, energy-conservation.
At present, domestic butt welding cigarette purifies great majority and adopts industrial filter cloth filtration method, wet method and active carbon adsorption, and this several method has the shortcoming that cannot overcome.As the density in industrial filter cloth wind hole and the contradiction between air force, and need often to change filter, safeguard that use cost is high; In wet-treating, while processing volume of smoke, the contradiction that exists the frequent replacing of chemicals and chemical tank to move; Charcoal absorption needs again long activation process.These contradictions all almost cannot overcome, adding current range hood great majority adopts fixed, this weldering cigarette that mobile welding gun is produced, uptake is few, a large amount of weldering cigarettes are diffused in air, and the suction journey of welding cigarette absorbing and purifying device in prior art is generally 300mm, suction journey is shorter, the inconvenient weldering cigarette that fully absorbs.At present, having a kind of device is that range hood is fixed on the mask that welder uses, although this method has solved range hood and has moved problem, but general mask is all beyond the fluerics of weldering cigarette, so, the range hood being arranged on mask can not all suck weldering cigarette in clearing machine, and pipeline is larger in addition, so to very inconvenience of workman's operation.
By patent retrieval, open about the technical scheme that the purifying treatment method of weld fumes is existing relevant, as: Chinese Patent Application No.: 201220363674.4, the applying date: on July 25th, 2012, invention and created name is: wearing piece reparation dedusting and purifying device, this application case includes dust suction casing, water tank, described dust suction casing top is provided with dust suction and enters joint, in dust suction casing, be provided with dust suction bottom half is separated to the filter for dust suction drawer chamber, dust suction drawer is provided with the drawer that can pull open in chamber, dust suction casing upper portion side wall is provided with pipe joint, on pipe joint, be connected to aluminium platinum flexible pipe, be positioned at dust suction casing and be also vertically provided with the screen pack that covers pipe joint and suction box body sidewall connectivity part, what on described water tank, be provided with smoke joint, access aluminium platinum flexible pipe enters cigarette joint, and tank top is provided with water inlet pipe, and water tank bottom is provided with outlet pipe.The flue dust that this application case can produce built-up welding reparation purifies, and reduced to a certain extent the pollution of built-up welding reparation to environment, but the purification efficiency of its weld fumes is low, and cannot follow the tracks of and absorb weldering cigarette according to the needs in the speed of welding and each orientation of welding.
