Abstract

The invention discloses a gas detonation device convenient to inflate. The gas detonation device comprises an inner pipe, an inner pipe filling cavity, a first inflation conductive head, a second inflation conductive head and an outer pipe. The inner pipe filling cavity is formed in the inner pipe, a first inner sealing cover and a second inner sealing cover are connected to the two ends of the inner pipe in a sealed mode correspondingly, and the outer pipe is arranged outside the inner pipe. A first outer sealing cover and a second outer sealing cover are connected between the inner pipe and the outer pipe. The inner pipe is in clearance fit with the first outer sealing cover and the second outer sealing cover, and the outer pipe is connected with the first outer sealing cover and the second outer sealing cover in a sealed mode. The first inner sealing cover and the second inner sealing cover are connected with the first outer sealing cover and the second outer sealing cover in a sealed mode correspondingly. The first inflation conductive head and the second inflation conductive head are mounted on the first inner sealing cover and the second inner sealing cover correspondingly, and an outer pipe filling cavity is located between the inner pipe and the outer pipe. The gas detonation device has the advantages of being low in manufacturing cost, high in reaction material mixing uniformity, high in heat releasing efficiency, good in transporting safety and high in detonation power.

Description

technical field [0001] The invention belongs to the technical field of blasters, in particular to a gas blasting device which is easy to inflate. 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 vaporize easil...
