Embodiment 1

[0081] A gas charge and ignition integrated detonator, such as figure 1 As shown, it includes a tube body 1, a filling cavity 2 and an inflatable ignition head 3. Inside the tube body 1 is a filling cavity 2. One end of the tube body 1 is connected to the gas-filled ignition head 3, and the other end of the tube body 1 is connected to a cover body 4. The compressive strength of the pipe body 1 is greater than 5.045Mpa; the pipe body 1 is a carbon steel cylinder or a stainless steel cylinder, and the filling chamber 2 is filled with a reducing agent and an oxidizing agent, and the oxidizing agent is liquid oxygen, supercritical oxygen or high-pressure gas Oxygen, the reducing agent is carbon-containing organic matter or reducing simple substance.

[0082] Such as figure 2 and image 3 As shown, the gas charging ignition head 3 includes a blocking base 31, an air filling hole 32, a sealing ball valve 33, a heating wire 34, a conductive joint 35 and a sealing locking screw 36, a...

Embodiment 2

[0094] The difference with embodiment 1 is: as Figure 4 As shown, the pipe body 1 includes a first segmented body 11 and a second segmented body 12, the first segmented body 11 and the second segmented body 12 are connected through a threaded structure, and are matched with a threaded sealing ring 13 for Sealing; the gas-filled ignition head 3 is respectively connected to one end of the first segment body 11 or the second segment body 11; this structure is convenient for charge.

Embodiment 3

[0096] The difference with embodiment 1 is: as Figure 5 As shown, the pipe body 1 is a composite layer tube containing fiber material, the pipe body 1 is made of a composite layer, and the pipe body 1 includes a matrix layer 101, a fiber layer 102 and a hardened layer 103, and the hardened layer 103 is located at The outer layer of the fiber layer 102, the matrix layer 101 is located in the inner layer of the fiber layer 102; the two ends of the pipe body 1 are respectively sealed and wrapped with a first metal joint 111 and a second metal joint 112, and the first metal joint 111 is threaded The sealing connection structure is connected to the gas ignition head 3, and the second metal joint 112 is connected to the cover body 4; the bottoms of the first metal joint 111 and the second metal joint 112 protrude outwards to avoid falling off from the tube body 1.

[0097] As a further description of the above embodiment, the base layer 101 is made of polyethylene (PE); the fiber l...

Abstract

The invention discloses an air inflation and ignition integrated blaster and a fracturing device. The air inflation and ignition integrated blaster comprises a tube body, a filling cavity located in the tube body, as well as an air inflation and ignition head and a cover body respectively located at the two ends of the tube body, wherein the filling cavity is filled with supercritical oxygen and a reductive simple substance; the air inflation and ignition head comprises a plugging substrate, an air inflation hole, a sealing ball valve, a conductive contact and an electric heating wire; the air inflation hole penetrates through the plugging substrate; a sealing shrink mouth is formed in the lower part of the air inflation hole; the sealing ball valve is mounted above the sealing shrink mouth; the conductive contact penetrates through the sealing ball valve and is fixedly connected with the sealing ball valve in a clamping manner; the spherical surface of the lower part of the sealing ball valve is a rough surface; the degree of tightness of the sealing ball valve is adjusted by a sealing locking screw; a contact window, through which the conductive contact penetrates, is formed in the middle of the sealing locking screw; the conductive contact is connected with the electric heating wire by a wire; and a connecting piece is connected between the plugging substrate and the cover body. The air inflation and ignition integrated blaster has the advantages that a powder filling process is simple, the safety is high, the mixing uniformity of materials is high, and the end of the blaster is prevented from flying out.

Description

technical field [0001] The invention belongs to the technical field of detonators, and in particular relates to a charge-ignition integrated 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 heat generation detonator ignites and gene...
