Assembly-type lead sealing gas blaster detonator and fracturing device

Abstract

The invention discloses an assembly-type lead sealing gas blaster detonator and a fracturing device. The assembly-type lead sealing gas blaster detonator comprises a shell, a filling cavity, an ignition mechanism and a gas filling mechanism. A filling cavity is formed in the shell. The shell is connected with the sealing ignition mechanism and the gas filling mechanism. The ignition mechanism comprises an electric heating wire, a guide wire, a guide wire through hole and a sealing base body. The electric heating wire is connected with the guide wire. The guide wire through hole is formed in the axis portion of the sealing base body. The guide wire penetrates through the guide wire through hole through an insulating layer outer coat. An internal thread hole is formed in one end of the guide wire through hole, and an inner sealing rubber ring is installed at the bottom of the internal thread hole. The internal thread hole is matched with a perforation screw, and a perforation hole is formed in the axis of the perforation screw. The guide wire penetrates through the inner sealing rubber ring and the perforation screw. The perforation screw is matched with the internal thread hole to compress the inner sealing rubber ring, so that the guide wire hole is sealed. The assembly-type lead sealing gas blaster detonator and the fracturing device have the advantages that manufacturing cost is low, reaction material mixing uniformity is high, heat release efficiency is high and transportation safety is good.

Description

technical field

[0001] The invention belongs to the field of detonating devices, in particular to a detonating device for an assembled lead wire sealed 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] Existing gas blasters mainly include a vaporization liquid storage pipe and a heating detonator installed in the vaporization liquid storage pipe; the heating detonation device ignites and generates...
