Abstract

The utility model discloses an electric welding smoke and dust purifier, which is characterized in that a plurality of universal air suction arms which can conveniently move are arranged in a workshop and are gathered on a main pipeline; the main pipeline is connected with an inlet of the purifier; the smoke dust gas is introduced into the purifier by a draught fan through the inlet and enters a shutter type spark blow-out precipitator at first, and spark and large dust particles are blocked by the blow-out precipitator and are blown out and precipitated. At the first stage, according to the spark blow-out precipitator, the spark is prevented from entering a filter layer so as not to burn a filter material, and partial large particles are precipitated; at the second stage, by adopting a needled bag, a filter effect is good; and at the third stage, the toxic gases are adsorbed by activated carbon. The purified gas can be recycled indoors.

Description

The welding soot purifying device

Technical field

The utility model relates to a kind of welding soot purifying device; This machine can use universal air-breathing arm (can hover in three-dimensional optional position; 360 degree easy and flexible arrive arbitrary orientation and send out dirt pits) purify welding fume to this clarifier of welding fume suction, also can be fixed on the circularly purifying processing that the workshop certain position is done the welding shop room air.

Technical background

The welding fume processor miscellaneous of people's use at present, for example: electrostatic precipitation purification style one-time investment is high, and many small business are unwilling to buy; The cleaning dust operating cost is high, and waste water is difficult to handle, and northern area freezes winter easily; Paper web deduster filter area is little, and filter efficiency is low, and deashing is inconvenient, and is not good to the clean-up effect of welding fume air; This dust removing purifier is when administering welding, cutting, polishing; Be created in a large amount of purifiers that suspend harmful tiny metallic particles and design in the air; Being adapted to a plurality of stations uses through the aspirating air pipe parallel connection; Its purification efficiency is high, is furnished with the long universal air-breathing arm of 2-3 rice, and is easy to operate.

Summary of the invention

The purpose of the utility model provides a kind of processor of welding soot purifying efficiently, for big rivet welding workshop environment purification uses.The weld job process is similar to a small-sized smelting process; The maximum temperature in welding arc district can reach about 5000 ℃; Under so high temperature, any metal and oxide thereof all can be melted, evaporate, and this process will produce dust, the pernicious gas of a large amount of gaseous states and graininess.Its chemical composition is very complicated, kind surplus in the of 20 nearly, and also there are pollution factors such as electromagnetic field of high frequency, ray, ionising radiation, noise in the working site.When adopting manual welding, operating personnel are apart from the not enough 1m place's operation of solder joint, and under the situation of not having effectively smoke evacuation, with sucking poisonous in a large number, harmful flue dust inevitably, the worker sucks these flue dust for a long time and is prone to suffer from occupational diseases such as pneumoconiosis and manganese poisoning.General ventilation thermal losses within doors is big, and flue gas is desirable scheme in the local ventilation clean room.

This practical sexual type is realized through following technical scheme to achieve these goals: the workshop is equivalent to a plurality of terminals of clarifier according to the universal easily air-breathing arm of a plurality of activities of location arrangements of producing flue dust; These universal air-breathing arms all are summarised on the total pipeline, and the inlet (1) of total pipeline and clarifier is connected, and flue dust gas is introduced clarifier by air-introduced machine (8) through inlet (1); At first get into blow-out settler (3), because the flue dust that has just sucked possibly have spark in the inside, spark receives stopping of venetian blind type arc arrester (2) with some big grits; Carry out simultaneously cyclonic separation here; Spark and big grit are deposited to ash bucket (14) earlier, and other flue dust continues to rise, and filters through cloth bag (5); Overwhelming majority soot dust granule just is filtered in the cloth bag outside, and what get into the cloth bag the inside generally is that harmful components are CO, CO ₂, O ₃, NO _X, CH ₄Deng gas; These gases are adsorbed when flowing through the active carbon (6) of cloth bag the inside; Clean space gets into clarifier case top (7) through cloth bag outlet (10), and the gas in the case top is drawn into discharge duct (9) through air-introduced machine (8), enters indoor then; Circulate in doors in the space, heat exhaustion is little.

The specific embodiment

For welding shop; The manual welding of stationary work-table is arranged, and hood can be taken weld fumes away basically, adopts the local ventilation mode can obtain regulation effect preferably; Indoor thermal losses is few; The northern area of special cold, the indoor hear rate of general ventilation is big, and indoor local ventilation is both economical control measures.Designed this indoor local ventilation clarifier to above situation.At first close ash discharging hole (4) before the use, open air-introduced machine 8, make whole system be in negative pressure state; The welding fume that produces when the electric welder works gets into flue dust inlet (1) through pipeline; Get into flue dust fire extinguishing, settler (3) then, flue dust receives stopping of louvre type arc arrester in the process that makes progress, and flue dust Mars extinguishes; The bulky grain grit is deposited to ash bucket under the effect of gravity simultaneously; The flue dust that rises is filtered by cloth bag (5), and dust is filtered in the cloth bag outside, and some pernicious gas CO, CO ₂, O ₃, NO _X, CH ₄And in the air entering cloth bag, pernicious gas is by the active carbon in the cloth bag (6) absorption, and clean air is through cloth bag outlet (10) entering fume purifier upper box body (7); Under the attraction of air-introduced machine (8), discharge, accomplished the purified treatment of welding fume, through timer control vibrator (11) through exhaust duct (9); Timing vibration card (12) through the vibration of card, is installed in the also vibration simultaneously of cloth bag on the card; The dust that accumulates in cloth bag outside so just drops in the ash bucket, reaches the effect of vibration ash disposal, to certain the time; Close air-introduced machine (8); Open the fan door of two on the clarifier casing (13), open ash discharging hole (4) again, discharge the dust of saving bit by bit in the ash bucket.Dust is pick-uped, and other deals with, and the active carbon in the cloth bag is regularly changed according to operating position, handles, and the active carbon after the processing can be recycled.Cleaned air passes can be emitted on indoor, and heat exhaustion is little.So just accomplished the purified treatment of indoor welding fume.
