Abstract

The invention discloses a plug-in type gas blaster. The plug-in type gas blaster comprises an inner tube, an inner tube filling cavity, an ignition mechanism, an inner tube gas inflation mechanism and an outer tube. The inner tube is internally provided with the inner tube filling cavity. A first sealed inner cover and a second sealed inner cover are connected to the two ends of the inner tube in a sealed manner correspondingly. The outer tube is arranged on the outer layer of the inner tube. A first sealed outer cover and a second sealed outer cover are connected between the inner tube and the outer tube in a sealed manner. The ignition mechanism and the inner tube gas inflation mechanism are mounted on the first sealed inner cover or the second sealed inner cover. The first sealed outer cover or the second sealed outer cover is provided with an outer tube gas inflation mechanism. A seal cavity formed between the inner tube and the outer tube is an outer tube filling cavity. The inner tube filling cavity is filled with supercritical oxygen and carbon-containing organic matter. The outer tube filling cavity is filled with liquid matter easy to gasify such as liquid carbon dioxide or liquid nitrogen. The plug-in type gas blaster has the beneficial effects of being low in manufacturing cost, high in reaction material mixing uniformity, high in heating efficiency, good in transportation safety and high in blasting power.

Description

technical field [0001] The invention belongs to the technical field of blasters, in particular to a plug-in gas blaster. 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 easily vaporized substances in...
