Embodiment 1

[0098] like figure 1 As shown, a reusable cylindrical aramid fiber gas blaster includes an energy storage device 1 and an inflatable detonator 2, one end of the energy storage device 1 is equipped with an inflatable detonator 2, and the other end is sealed or integrally formed; The energy device 1 is made of solidified aramid fiber material. The energy storage device 1 is cylindrical; Window 31, the energy-dissipating window 31 is sealed and installed with a constant-pressure burst disc 32, and the energy-dissipating inner cover 3 is made of metal.

[0099] As a further specific description of the above implementation, the energy storage device 1 has a two-layer structure, and the energy storage device 1 includes a mesh layer 12 and a hardened layer 13 distributed from the inside to the outside.

[0100] As a further specific description of the above implementation, the inflatable detonating device 2 includes a sealing base 21 , and an inflating mechanism 22 and an detonating...

Embodiment 2

[0114] Embodiment two: the difference with embodiment one is: (such as figure 2 As shown), the energy storage device (1) has a three-layer structure, which is a base layer (11), a mesh layer (12) and a hardened layer (13) from the inside to the outside; the mesh layer (12) is aromatic The hardened layer (13) is made of epoxy resin glue material, and the base layer (11) is made of polyethylene material.

Embodiment 3

[0115] Embodiment three: the difference with embodiment two is: (such as image 3 As shown), the threaded structure in the middle of the sealing base 21 is inwardly recessed; this structure is convenient for transportation and saves the overall volume, and at the same time, it is convenient for protecting the inflatable detonator 2 from being hit.

Abstract

The invention discloses a cylindrical aramid fiber gas blasting machine capable of being repeatedly used and a manufacturing method thereof. The cylindrical aramid fiber gas blasting machine capable of being repeatedly used comprises an energy storage device and an inflation detonation device; the detonation device is arranged at one end of the energy storage device, the other end of the energy storage device is sealed or integrally molded, and the machine is characterized in that the energy storage device is formed by curing of aramid materials, the energy storage device is cylindrical, an energy releasing inner cover is arranged on the inner layer of the bottom of the energy storage device, an energy releasing window is formed in the energy releasing inner cover, a fixed-pressure blasting piece is arranged on the energy releasing window in a sealing manner, and the energy releasing inner cover is made of a metal material; the cylindrical aramid fiber gas blasting machine capable of being repeatedly used has the beneficial effects of being small in thickness, small in weight, convenient to transport and mount, easy to manufacture, low in consumable cost, low in production cost, rapid in inflation, good in seal performance, long in service life and the like.

Description

technical field [0001] The invention belongs to the field of blasting, and relates to a blasting device, in particular to a reusable cylindrical aramid fiber gas blaster and a manufacturing method thereof. Background technique [0002] Gas blasting technology is the use of gasification and expansion of liquid or solid substances that are easy to gasify to generate high-pressure gas, so that the surrounding medium expands to do work and cause fragmentation; gas blasting technology is widely used in mining, geological exploration, cement, steel, electric power, etc. Industry, subway and tunnel and municipal engineering, underwater engineering, and emergency rescue. At present, the equipment used in gas blasting technology is a gas blasting tube. The blasting tube mainly includes an inflatable structure, a detonating structure, an expansion medium storage structure and a sealing structure. It has the following disadvantages: [0003] At present, the expansion medium storage st...
