Gas blasting machine convenient to inflate

Abstract

The invention discloses a gas blasting machine convenient to inflate. The gas blasting machine comprises an inner pipe, an inner pipe filling cavity, a first inflating conductive head, a second inflating conductive head and an outer pipe, wherein the inner pipe filling cavity is formed in the inner pipe; a first sealing inner cap and a second sealing inner cap are respectively in sealing connection to two ends of the inner pipe; the outer layer of the inner pipe is the outer pipe; a first sealing outer cap and a second sealing outer cap are connected to between the inner pipe and the outer pipe; the inner pipe is in clearance fit with the first sealing outer cap and the second sealing outer cap; the outer pipe is in sealing connection with the first sealing outer cap and the second sealing outer cap; the first sealing inner cap is in sealing connection with the first sealing outer cap, and the second sealing inner cap is in sealing connection with the second sealing outer cap; the first inflating conductive head is mounted in the first sealing inner cap, and the second inflating conductive head mounted in the second sealing inner cap; and an outer pipe filling cavity is formed between the inner pipe and the outer pipe. The gas blasting machine disclosed by the invention has the advantages of being low in manufacturing cost, high in homogeneity degree of reacting materials, high in heat releasing 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 gas blaster 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 easily vapori...
