Abstract

The utility model relates to a welding smoke purifying device used for purifying smoke dust generated in a large-scale welding shop. A smoke sucking cover is firstly fixed on a torch head in the welding smoke purifying device; the smoke dust enters the corona accumulation region of the welding smoke purifying device through the smoke sucking cover, a light hose and a smoke sucking pipe; corona charge is carried out through a barrel type high pressure coagulator and a metal disc coagulator rotating at high speed to make the micro smoke dust accumulated and charged for dust collection, and then the purified air is exhausted out of the welding smoke purifying device through filtration; an automatic cleaning mechanism is arranged in a secondary accumulation region, and a filter bag group is provided with brushes which automatically rotate for brushing. The welding smoke purifying device can inhale 99.9% of the smoke dust, and the air purifying rate can achieve more than 95%. One welding smoke purifying device can simultaneously process welding smoke produced by 10-15 electric welders.

Description

The utility model relates to a kind of strengthen environmental protection, improves the dedusting and purifying device of welder's operating condition.Be mainly used in the weldering fume purifying apparatus of the flue dust that purifies large-scale welding shop welding generation.
In fields such as boiler manufacturing, heavy-duty machinery, vehicle manufacturing, the manufacturing 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 all arranged, when these welding machines were worked simultaneously, flue gas manganese dust content was generally up to 30mg/m in the workshop 3More than, also contain other metallic vapour, seriously polluting air, the harm welding personnel and around personnel healthy.Present domestic butt welding cigarette purifies great majority and adopts the industrial filter cloth filtration method, wet method and active carbon adsorption, and this several method all has the shortcoming that can't overcome.Exempt to press and weld the contradiction of flue dust grain between small as the density in industrial filter cloth wind hole and air quantity and suction; In wet-treating, exist when handling volume of smoke, with the contradiction that chemicals is frequently changed and chemical tank moves; Charcoal absorption needs long activation process again.These contradictions all can't overcome, and add present range hood great majority and adopt fixedly, and this is concerning the weldering cigarette that the welding gun that moves produces, and uptake is few, and a large amount of weldering cigarettes are diffused in the air.It is that range hood is fixed on the mask that the welder uses that a kind of device is arranged, though 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 that is positioned on the mask can not be with in the whole inhalation machines of weldering cigarette, pipeline is bigger in addition, so to very inconvenience of workman's operation.
It is the principle that corona effect makes small soot dust granule cohesion control of dust that the purpose of this utility model is exactly the applying high voltage cohesion charged, designs a kind of all kinds of equipment that carry out the workshop smoking dedusting of weld job of large, medium and small type that are applicable to---the weldering fume purifying apparatus.This function is followed the tracks of absorption to the flue dust that welding gun produces to any one in the workshop, and cleaned air passes is entered indoor.
Weldering fume purifying apparatus described in the utility model is to be made of range hood, Smoking pipe, corona flue dust condensation region, the several parts in filtrating smoke dust district.It is that range hood is installed in above the rifle head of welding gun, range hood and welding gun are become one, during work, range hood moves with welding gun and moves, in the weldering cigarette inhalation mask that can in time welding gun be produced, dust shield links to each other with the multichannel plug of Smoking pipe one end by universal heatproof lightweight flexible pipe like this, and the weldering cigarette is by multichannel plug process Smoking pipe, under the suction function that blower fan produces, be inhaled in the weldering fume purifying apparatus.After the weldering cigarette process mesh homogenizer homogenizing, import the tubular knockouts, under the effect of high voltage electric field, tentatively condense, the small charged bigger particle (being corona effect) that becomes of the preliminary cohesion of soot dust granule process by smoke guiding cover.Flue dust through preliminary cohesion is imported into the secondary high-pressure condensation region again, under the effect of high pressure and negative pressure, flue dust is gathered into larger particle, under the centrifugal action of rotation at a high speed, be projected to filtering area again, air is cleaned by the filter bag group and gets back to indoorly under the effect of blower fan, and flue dust is blocked and has stayed in the weldering fume purifying apparatus.
This device range hood and welding gun are molten to be one, when welding personnel is worked, the lonely together light of welding gun produces flue dust immediately, range hood will weld cigarette effectively and all suck and weld in the fume purifying apparatus this moment, because this range hood is on welding gun, can move and move with welding gun, therefore butt welding cigarette absorptivity can reach 99.9%, this range hood adopts aluminium sheet to make, Smoking pipe adopts the lightweight flexible pipe, so the workman is easy to operate, does not increase the weight of welding gun again too much, through the test of environmental administration's manganese electric test method, the purification efficiency of native system machine reaches more than 95%.A weldering fume purifying apparatus can be handled 10~15 weldering cigarettes that electric welding machine produced simultaneously.
