Vacuum environment-friendly explosive welding workshop

Abstract

The invention discloses a vacuum environment-friendly explosive welding workshop which comprises a workshop body, a vacuum pump and an explosive welding table. A vacuum gas suction opening is formed in a roof beam at the upper end of the workshop body. The vacuum pump communicates with the vacuum gas suction opening through a vacuum suction pipe. A vacuum valve is further installed at the positionof the vacuum gas suction opening. The explosive welding table is installed at the bottom end of the inner side of the workshop body. By means of the vacuum environment-friendly explosive welding workshop, due to the fact that the interior of the airtight workshop body is sucked to be in a vacuum state through the vacuum pump, impact waves and noise generated by exploding are reduced, in addition, energy generated by explosives does not make contact with air and is dispersed, and effective energy of an explosive composite plate is improved; and water-resisting type low-exploding-speed emulsion explosives are selected as the explosives, a water column covering layer is broken at the exploding moment of the explosives, the water column covering layer is broken, splashed flying mist attenuates the exploding impact waves and noise, meanwhile, part of waste gas is diluted, and part of dust is attached; and the rest of waste gas and dust can be recycled in the airtight workshop through a water mist spraying and gas extracting and exhausting system after standing, and the environment is prevented from being polluted.

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
