Abstract
The utility model provides a comprehensive treatment device for removing welding fume, and is suitable for the large scale welding department to use. A face protector is provided with a dust hood which is connected with a universal joint, an air hose, a big rocker arm, a rotation mechanism, a branch pipe and an air main which opens into the outdoors. The air main is connected with an exhaust fan and a welding fume purifier. The big rocker arm of the comprehensive treatment device is provided with a bear and a small rocker arm, and then, the rotation of the comprehensive treatment device and the operation of the face protector are flexible. The welder holds the face protector which is provided with the dust hood when working. When the welding gun raises the arc light and generates the smoke, the welding fume can be inbreathed into the dust hood right away because that the dust hood is near to the position of the generation of the smoke. The flue gas and the smoke are transacted by the centralized processing after passing through the pipeline and going into the purifier.
Description
The utility model belongs to a kind of device of strengthen environmental protection.Be mainly used in the smoke pollution of administering large-scale welding shop, so that air cleaning.
At large-scale welding shop, welding sequence as rivet welding workshops such as coal mine machinery factory, mining machinery plant, rolling stock plant, automobile factory, shipyards, in the workshop, generally all there are tens or up to a hundred electric welding machines to work simultaneously, flue gas manganese dust content is up to every cubic metre 30 milligrams in the workshop, the serious air that polluting is endangering the healthy of workman.The dust suction purifier of domestic a large amount of uses at present has fixed purifier of unit and the fixing additional dry collector of dust shield, these two kinds device suction air volumes are little, dust shield can not move along with the welding gun that the welder uses, therefore, when the flue gas of welding when dust shield is far away, dust shield just can not all be drawn into flue gas in the purifier timely, makes the rapid diffuse pollution environment of flue gas.Fixedly dust shield adds dry collector, and secondary pollution in time be handled so that be caused to dust exhaust apparatus can not to flue dust after flue gas manganese dirt sucks.
In order to overcome above-mentioned shortcoming, the utility model is established a kind of device that uses of skill in large-scale welding shop, this device can be to the flue gas that each welding gun produced in the workshop, flue dust follow the tracks of to absorb, and makes firm generations of flue gas also have little time diffusion and then is inhaled into to concentrate then in the dust shield and adopts the wet dust removal processing to prevent secondary pollution.
The utility model is an electric welding smoke comprehensive controlling device, this device is that a dust shield (4) is installed on protective face mask (6), dust shield (4) and protective face mask (6) are become one, during work, dust shield (4) protective face mask (6) moves along with moving of welding gun simultaneously, in time the flue gas that welding gun produced is sucked in the dust shield, dust shield (4) links to each other with pneumatic hose (3) by universal joint (5), pneumatic hose (3) connects big rocking arm (1), big rocking arm (1) is a tubulose, connect rotating mechanism (12) and connect branch wind pipe (13) by rotating mechanism (12), branch wind pipe (13) connects air main (7), and air main (7) leads to centrifugal iron sheet air exhauster of the homemade 4-72-11 type of outdoor connection and HY-Q type weldering fume purifier.On big rocking arm (1), supporting (9) is installed, the other end of supporting (9) is made cover tubular skewer and is gone on the axle (10), axle (10) can be fixed on the factory building column (11), big rocking arm (1) can be by the rotation of supporting (9) on axle (10) and rotatable 180 degree of rotation of rotating mechanism (12), on big rocking arm (1), a small rocker (2) is housed, rotatable 360 degree of small rocker (2), and drive pneumatic hose (3), dust shield (4) and protective face mask (6) rotate, the tumbler of small rocker (2) can be realized with bearing, universal joint (5) can make on the protective face mask (6) of band dust shield (4), down, a left side, right rotation flexibly, the protective face mask (6) of band dust shield (4) is gone up and is suspended on the industrial building column (11) with steel wire rope (8) in small rocker (2) with balance weight hanging, can alleviate the weight of the hand-held protective face mask of workman.
This device dust shield and protective face mask are molten to be one, when Welder's man-hour one hand-held welding gun, one hand-held protective face mask, welding gun arc light is together given birth to cigarette immediately, and this moment, dust shield was apart from arcing point about 200 millimeters, and the weldering cigarette has little time diffusion and is inhaled in the dust shield therefore pick-up performance the best at once, move on welding gun side weld limit, the dust shield protective face mask also moves thereupon, therefore can follow the tracks of absorption by the butt welding cigarette, and the absorptivity of flue dust can be reached more than 96%.It is little that this device takies construction area, do not influence overhead traveling crane work.Be drawn into flue gas, flue dust in the air main by dust shield, concentrate and adopt wet cleaning to handle, non-secondary pollution, air exhauster and weldering cigarette cleaning equipment are installed in outdoor, are convenient to unified management.A weldering fume purifier and air exhauster can be finished the dust suction work of treatment of 15 to 20 electric welding smoke comprehensive controlling devices, save the energy, the utilization rate of equipment and installations height.
Accompanying drawing is this device installation diagram.
Number in the figure is as follows:
1. big rocking arm 2. small rockers
3. pneumatic hose 4. dust shields
5. universal joint 6. protective face masks
7. air main 8. steel wire ropes
9. support 10.
11. column 12. rotating mechanisms
13. branch wind pipe
This device dust shield (4) is installed in above the protective face mask (6), dust shield (4) is connected with pneumatic hose (3) by universal joint (5), pneumatic hose connects big rocking arm (1), big rocking arm (1) connects branch wind pipe (13) by rotating mechanism (12), branch wind pipe (13) can be fixed on the column (11), and then connect air main (7), air main (7) leads to outdoor connection air exhauster and weldering fume purifier, big rocking arm (1) is by the rotation of supporting (9) on axle (10) and rotatable 180 degree of rotation of rotating mechanism (12), rotatable 360 degree of small rocker (2), dust shield tracking weldering in man-hour cigarette sucks flue dust in the dust shield, flue dust is through pneumatic hose (3), big rocking arm (1), branch wind pipe (13) enters air main (7), and then the outer weldering fume purifier of inlet chamber is concentrated wet processed.
