Abstract

The invention discloses a thimble sealed type trigger and a cracking device. The thimble sealed type trigger comprises a shell, a filling cavity, an ignition mechanism and an air inflation mechanism. The inside of the shell is the filling cavity, and the shell is connected with the sealed ignition mechanism and the air inflation mechanism. The filling cavity is filled with supercritical oxygen and carbonaceous organic material or elementary substance with reductibility. The air inflation mechanism comprises an air inflation hole, a valve rod and an air inflation valve seat. The middle of the air inflation hole is an air locking cavity, and the valve rod is movably installed in the air locking cavity through a thread structure. An ejector header and an ejector header sealed ring are installed at the top of the valve rod, and the ejector header is sleeved with the ejector header sealed ring. The thimble sealed type trigger and the cracking device have the advantages that manufacturing cost is low, mixing uniformity of reaction materials is high, heat releasing efficiency is high, and conveying safety is good.

Description

technical field

[0001] The invention belongs to the technical field of detonators, and in particular relates to a thimble-sealed detonator and a cracker. 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...
