Vacuum environmental protection explosion welding workshop

Abstract

The invention discloses a vacuum environment-friendly explosive welding workshop, which comprises a main body of the workshop, a vacuum pump, and an explosive welding table. A vacuum exhaust port is provided on the roof beam at the upper end of the workshop main body. A vacuum valve is also installed at the center, and an explosive welding table is installed at the bottom of the inner side of the main body of the workshop. The invention uses a vacuum pump to evacuate the interior of the main body of the airtight workshop into a vacuum state, reducing the shock wave and noise generated by the explosion, and the energy generated by the explosive is not lost in contact with the air, and the effective energy of the explosive composite board is improved; the explosive uses a water-resistant low detonation velocity Emulsion explosives, when the explosive explodes, the water column covering layer breaks, the water column covering layer breaks, and the sprayed mist attenuates the explosion shock wave and noise, and at the same time, dilutes part of the exhaust gas and attaches part of the dust; After standing still, it can be recycled by spraying water mist and exhaust system to avoid polluting the environment.

Description

technical field [0001] The invention relates to the technical field of explosive welding, in particular to a vacuum environment-friendly explosive welding workshop. Background technique [0002] With the development of the global economy, the demand for explosive composite materials in both international and domestic markets is increasing year by year. At present, it can be seen from market research that my country's explosive welding composite panel products account for almost half of the world's composite panel market. This requires our explosive welding companies to carry out technological innovations in order to cope with fierce market competition. Under the premise of meeting the national environmental protection requirements , to produce more and better explosive composite products. [0003] At present, when the clad plate is prepared by the conventional explosive welding method, there is air in the gap between the base and the clad plate before detonation. Therefore, ...

AI Technical Summary

Problems solved by technology

[0003] At present, when the clad plate is prepared by the conventional explosive welding method, there is air in the gap between the base and the clad plate before detonation. Therefore, during the explosive cladding process, problems such as bulging, low bonding rate and welding failure may occur due to the gap gas, which seriously affects the explosion. The efficiency and cost of welding; at the same time, a large amount of explosives are required in the conventional explosive welding process, but in fact only a small amount of explosives play the role of explosively driving the doubler plate, and most of the energy of the explosives is dissipated in the air in the form of shock waves. And the noise produced by the explosion can still reach 80-90 decibels 5 kilometers away, which has caused serious harm to the surrounding environment and the physical and mental health of personnel; damage

In order to reduce the above adverse effects, most of the current explosive welding sites are in remote mountainous areas, and the traffic is extremely inconvenient, which requires a lot of material transportation costs

In addition, a large amount of exhaust gas generated after the explosion will cause serious pollution to the surrounding atmospheric environment if it is operated in an open environment
