Description

technical field [0001] The invention belongs to the technical field of blasters, in particular to an integrated gas blaster with an inflatable lead wire. Background technique [0002] Gas blasting technology is to use the vaporization and expansion of easily vaporized liquid or solid substances to generate high-pressure gas, which makes the surrounding medium expand to do work and cause fragmentation. It has the characteristics of no open flame, safety and high efficiency. [0003] Carbon dioxide gas blasters are typical blasting equipment in gas blasting technology, and are widely used in mining, geological exploration, cement, steel, electric power and other industries, subways and tunnels, municipal engineering, underwater engineering, and emergency rescue. [0004] The existing gas blaster mainly includes a vaporization liquid storage pipe and a heating detonator installed in the vaporization liquid storage pipe; the heating detonator ignites and generates heat to vapori...

AI Technical Summary

Problems solved by technology

[0006] Adopt the gas blaster of above-mentioned detonator structure, existing problem is: 1, the thermal reaction material that needs to fill in the detonator needs to carry out the processing of processes such as material mixing, mixing evenly, rolling material or bagging, filling process It is time-consuming and labor-intensive, and the manufacturing cost is high; 2. During the filling process of the detonator, the oxidant and reducing agent are prone to uneven mixing, resulting in low heat release efficiency; 3. The thermal reaction material needs to be mixed and filled in advance. If the medium temperature is too high, it will easily cause combustion or explosion, which has great potential safety hazards; 4. Due to the damp, deterioration or deformation of the detonating material, it is easy to cause squibs, and it is impossible to determine the cause of the squibs, so it cannot pass The squib method eliminates potential safety hazards; 5. The detonation method of the existing gas blaster uses a solid activator to burn to generate high temperature, which directly conducts heat to the liquid carbon dioxide, causing the liquid carbon dioxide to gasify and expand, and the heat absorption efficiency of the liquid carbon dioxide is low; 6. The detonator The heat release rate is slow, the chemical reaction is insufficient, the heat release efficiency is low, the pressure of the liquid is relatively small after gasification, and the blasting power is small; 7. After the blasting, the reactants in the detonator produce a large amount of toxic and harmful gases. , such as hydrogen sulfide, sulfur dioxide, nitrogen monoxide, nitroge
