Description

Electrostatic double-zone purifier for fume

The utility model relates to a kind of welder's of improvement occupational health condition, strengthens the two-region static dust purifier of indoor environment protection.This machine is mainly used in large-scale welding shop air cleaning, the local and inner solder joint smoke and dust treatment aspect of weldment.

In many mechanical industries, all have large-scale welding shop, as fields such as shipbuilding, generating set manufacturing, vehicle manufacturing, the manufacturings of heavy-duty machinery boiler.In these workshops, tens, up to a hundred electric welding machines or tens of large-scale automatic welding devices are generally all arranged, when these welding equipments were worked simultaneously, flue gas manganese dust content was generally up to 30mg/m in the workshop ³More than, wherein also have other metal vapors and oxide, seriously polluting air, personnel's was healthy around the harm welding personnel reached.At present, domestic butt welding cigarette administers most of employing work filter clothes or filter paper is added process of active carbon improvement, and its effect and service life are not good, safeguard very difficulty yet.Domestic also have another kind to weld fume purifying apparatus; it is that range hood is fixed on the welding gun; this point is impracticable to the welding gun of non-carbon-dioxide arc welding; because welding rod is all about 30cm; when welding at the beginning; the weld spacing welding gun just has 30cm; so the range hood that is fixed on the welding gun can not all suck the weldering cigarette in the purifier at all; this is an one; its two its condensation region be adopt two at a high speed the rosettes of rotation form; just can not carry out at any time the work of cleaning with water of the collecting plate in the condensation region like this, must wait high pressure to interrupt just carrying out collecting plate and clean work with water.If the band high pressure is cleaned collecting plate with water, high pressure very easily punctures, and burns device, its three because it is subjected to the restriction of structural design, its produced product is also very heavy, and does not have light-operated start stop apparatus, so to workman's operation and safeguard very inconvenience.

The high pressure that the purpose of this utility model adopts inversion transformation technique (or high-tension transformer) to produce exactly, corona principle by high-pressure electrostatic makes small soot dust granule be condensed into very big particle phenomenon, designs a kind ofly to be suitable for that large-scale welding shop purifies air and inner equipment---the two-region static dust purifier that purifies flue dust of widget.

Two-region described in the utility model static dust purifier is made up of a few parts such as triangle crane, range hood, silicon photocell (photo resistance), smoking pipeline, flue dust condensation region, filtrating smoke dust districts.It is that triangle crane one end is fixed on above the rifle head of welding gun, and the other end is fixed on the range hood, range hood is moved with welding gun and moves, and can make range hood follow the tracks of solder joint again, so, in the whole inhalation masks of flue dust that this range hood can welding produces.Range hood links to each other with main frame by heatproof spring plastic flexible pipe.Flue dust is through Smoking pipe, under the suction function that blower fan produces, be inhaled in the dust purifier, after flue dust process flue gas-dividing plate and the mesh homogenizer homogenizing, import the one-level condensation region by the one-level smoke guiding cover, carry out the one-level cohesion under the high voltage electric field effect, the particle that the small charged one-tenth of soot dust granule initial ionization is bigger (being corona effect) is imported into the secondary condensation region again through the flue dust of one-level cohesion, is condensed into bigger particle in high voltage electric field once more.These are adsorbed on the soot dust granule on the high-speed motion belt sheet metal, are cleaned out through cleaning brush, enter filtering area, are caught by the filter bag group then.Under the negative-pressure air fan effect, outside the cleaned air passes discharge machine, and flue dust is blocked and stays in the dust purifier, regularly to falling.

Range hood of this machine and welding gun, solder joint are that one is in two-dimensional space motion deeply.When welding personnel was worked, welding gun during arc light, made the controllable silicon conducting by silicon photocell (or photo resistance) together, started clearing machine, and arc light one disappears the clearing machine autostop.Therefore welder's operation is extremely convenient, and range hood again can be with in the whole inhalation masks of flue dust, and this range hood adopts the lightweight thin aluminum sheet to make, and Smoking pipe adopts the light plastic bourdon tube, so whole welding gun is not gained in weight too much.Test through environmental administration and labour department to flue gas manganese dirt chemical method, this machine purification efficiency can reach 98%.Various ways such as this machine can be made portable, and is portable and fixed can be followed the tracks of absorption cleaning to the flue dust that welding gun produces in all directions to any one in the workshop, and cleaned air passes is discharged outside the machine.
