Abstract
The invention discloses a wave blocking device for explosive welding air impact waves. The wave blocking device comprises a semispherical steel container (2) fixed and reinforced by backfill soil, wherein reinforcing rib plates (1) are arranged vertically and transversely on the outer part of the container in a crossed manner; one side of the lower part of the container is connected with a barrel-shaped wave blocking device exiting and entering channel (6) and an exiting and entering door is additionally arranged; a smoke exhausting opening (3) is formed in the top of the container; a water bag (5) for completely covering the smoke exhausting opening is arranged on the smoke exhausting opening by arranging a covering object supporting frame (4). According to the wave blocking device, the water bag at the top of the smoke exhausting opening of an air wave blocking device is additionally arranged to cover, so that an influence range of the air impact waves caused by explosive welding is reduced effectively and the strength of the air impact waves is weakened obviously; the influences on people, buildings and the like in a certain range of the periphery by the explosive welding are controlled in a safe range; meanwhile, the influences of smoke dust and harmful gas, caused by explosion, are reduced by breaking and scattering the water bag under the effect of the impact waves, so that the aim of green and environment-friendly explosive machining is realized.
Description
Technical field
The present invention relates to the explosion welding technique field, more particularly, relate to the improvement of explosive welding protection equipment.
Background technology
The clad steel plate of explosion welding technique production has been widely applied in the industries such as oil, chemical industry, metallurgy, machinery, Aero-Space, national defense construction and field in a large number, the explosive welding composite had both met the demand of each field antagonism burn into of every profession and trade special or rare expensive functional metal materials such as high temperature resistant, these material and facility manufacturing costs have also been saved, for significant contribution has been made in social development.Yet current explosion welding technique is characterized as the surface that explosive is laid in the function sheet metal and carries out exposed blast, the air-shock wave after blast, earthquake sheet, flue dust and pernicious gas become important restraining factors of this technical development.Especially the air-shock wave that explodes, its coverage is large, is the overriding concern factor of explosive welding processing enterprise Choice and process place and surrounding environment, is also that can explosive processing enterprise be engaged in the Main Basis of explosive processing operation at the three unities.At present also there is no effectively to eliminate the air-shock wave technology that explosive welding causes.
Summary of the invention
For the problems referred to above, the present invention seeks to invent a kind of wave resistance device of explosive welding air-shock wave, by the water bag that increases air wave resistance device top exhaust opening, cover, effectively dwindle the air-shock wave coverage that explosive welding causes, air-shock wave intensity is obviously weakened, by explosive welding processing to the people in certain limit on every side, the impact of construction of structures etc. is controlled in safe range, simultaneously, unrestrained the reaching of breaking under shock wave by water bag reduced flue dust that blast causes and the impact of pernicious gas, utilize water smoke reduce the flue dust of blast generation and absorb the pernicious gas that blast produces, and then reduce and explosive charge produces while weakening explosive welding air-shock wave to the security implication of the people in certain limit, construction of structures etc., reach the purpose of environmental protection explosive processing.
In order to achieve the above object, the invention provides a kind of wave resistance device of explosive welding air-shock wave, comprise the hemisphere shape steel vessel of fixing and strengthening by backfill soil, the crisscross reinforcement gusset that is provided with in the outside of hemisphere container; Described hemisphere container bottom one side connects tubular wave resistance device Vomitory, and adds access door; Described hemisphere container top is offered exhaust opening, and described exhaust opening place is provided with by the covering bracing frame is set the water bag that covers described exhaust opening fully.
Under optimal way, the domes that described access door is evagination, and be equipped with cross arch reinforcement.In addition, under optimum way, the hemisphere container is 20mm thickness 20# steel welding main body, and this selection can effectively reach the protective action of explosive welding, makes manufacturing cost minimum simultaneously.
Beneficial effect of the present invention is:
1. the present invention has designed and produced the hemispherical container of an explosive welding processing, and explosive welding operates in container and operated, and owing to having closure, the explosive welding operation is not subject to the impact of strong wind weather.
2. the wave resistance device of the explosive welding air-shock wave that the present invention designs and produces, changed the direct aerial route of transmission of air-shock wave that explosive welding causes, thereby effectively weakened the impact of shock wave on people in certain limit on every side and construction of structures.
3. the wave resistance device of the explosive welding air-shock wave that the present invention designs and produces, the metal edge strip flown out in the time of can stopping by explosive welding processing composite plate fully, thereby improved the security of explosive welding processing, the fence coverage while having dwindled construction, improved working (machining) efficiency.
4. the wave resistance device of the explosive welding air-shock wave that the present invention designs and produces, be provided with steel structure frame and the water bag of exhaust opening, after explosive charge, water bag occurs broken when stopping shock wave, water becomes water smoke from exhaust opening, this had both effectively intercepted the propagation of air-shock wave, do not affect the gas purging that blast produces, but also reduced to a certain extent the fume amount that explosive welding produces, can also the absorption portion blast produce pernicious gas (as nitrogen oxide, hydrogen sulfide, carbon dioxide etc.), make explosive welding processing environmental protection more.
The accompanying drawing explanation
Fig. 1 is the wave resistance device theory structure schematic diagram of explosive welding air-shock wave of the present invention.
In figure: 1, the reinforcement of device; 2, hemispherical wave resistance device main body; 3, exhaust opening; 4, covering bracing frame; 5, wave arrestment water bag; 6, wave resistance device gateway.
The specific embodiment
As shown in Figure 1, the present invention plants the wave resistance device of explosive welding air-shock wave, adopts during welding for steel structure to make a hemispherical container 2, and container 2 tops are provided with exhaust opening 3, and the container front end is provided with access door by Vomitory 6.
The preferred 20mm structure 20# steel welding of container 2 main body, the mode that adopts lacing wire to strengthen makes structure have mechanical stability and mechanical strength (number in the figure 1 is for strengthening gusset).Access door adopts arch to lengthen and adopt cross arch reinforced structure.Whole container adopts backfill soil be fixed and strengthen after building.Add man-hour in explosive welding, after the sheet material of explosive processing is entered and installed by gateway, adopt steel structure framework 4 to cover exhaust opening 3, and add water bag 5 coverings above steel structure framework.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
