Description

A kind of pair of blower fan weldering cigarette absorption cleaning device
Technical field
The invention belongs to weldering cigarette processing technology field, more particularly, the present invention 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, tens of, up to a hundred electric welding machines or several large-scale automatic welding devices are generally arranged, when these welding machines are worked simultaneously, in workshop, weld fumes content is very high, is seriously polluting air, and around the harm welding personnel reaches, personnel's is healthy.The welding method that produces the 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 the modern industry field, the welding of metal material is one of most basic structural member manufacturing procedure.Yet, in the 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, in the situation that improper ventilation, dust concentration exceeds the national standard several times usually, can cause the multiple occupational hazards such as electric welder pneumoconiosis, manganese poisoning, respiratory inflammation, nervous breakdown.
At present, the method that the 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 zone of workpiece, and smog is carried out to collection and treatment, although the method is simple to operate, the exhausting area is larger, therefore whole exhausting amount is large, energy consumption is high, and the smoke abatement effect is undesirable; Another kind is to adopt point-to-point mode, and the weldering cigarette produced 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 can't 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 can't 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 in prior art, the suction journey of weldering cigarette absorbing and purifying device is generally 300mm, and the suction journey is shorter, the inconvenient weldering cigarette that fully absorbs.At present, it is that range hood is fixed on the mask that the welder uses that a kind of device is arranged, 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 be arranged on mask can not all suck the weldering cigarette in clearing machine, and pipeline is larger in addition, so to very inconvenience of workman's operation.
By patent retrieval, the technical scheme existing relevant about the purifying treatment method of weld fumes is open, 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 the dust suction casing, water tank, described dust suction casing top is provided with dust suction and advances joint, be provided with the dust suction bottom half is separated to the filter for dust suction drawer chamber in the dust suction casing, the dust suction drawer is provided with the drawer that can pull open in chamber, dust suction casing upper portion side wall is equipped with pipe joint, be connected to aluminium platinum flexible pipe on pipe joint, be positioned at the dust suction casing and also vertically be provided with the screen pack that covers pipe joint and suction box body sidewall connectivity part, what be provided with smoke joint, access aluminium platinum flexible pipe on described water tank advances the cigarette joint, and tank top is equipped with water inlet pipe, and water tank bottom is equipped with outlet pipe.The flue dust that this application case can produce the built-up welding reparation is purified, 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 can't absorb the weldering cigarette according to the speed of welding and the needs tracking in each orientation of welding.
