One-time aramid fiber gas blaster and manufacturing method thereof

Abstract

The invention discloses a one-time aramid fiber gas blaster. The one-time aramid fiber gas blaster comprises an energy storing device 1, a detonating structure 2 and an inflation mechanism 3. The detonating structure 2 and the inflation mechanism 3 are mounted at one end of the energy storing device 1. The other end of the energy storing device 1 is sealed or integrally formed. The energy storing device 1 is made from a material with the compressive strength being higher than 345 Mpa. The one-time aramid fiber gas blaster has the advantages that 1, the one-time aramid fiber gas blaster is small in thickness, low in weight and convenient to transport and mount; 2, the one-time aramid fiber gas blaster is easy to manufacture, low in material cost and low in production cost; 3, inflation is rapid; 4, the tightness is good, the service life is long, and the cycle life is long; 5, the one-time aramid fiber gas blaster is easy to restore after blasting deformation, the maintaining cost is quite low, and the one-time aramid fiber gas blaster can be restored on site and is good in stability after energy is stored; 6, the yield is high; and 7, the manufacturing process is simple.

Description

technical field [0001] The invention belongs to the field of blasting, and relates to a blasting device, in particular to a gas blaster. 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 energy, 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 structure used in gas blasting technology is mainly a steel pipe or ...

AI Technical Summary

Problems solved by technology

[0011] The object to be realized by the present invention is: to reduce the weight of the existing gas blaster, reduce the production cost, and compare with the prior art, the storage energy of the steel cylinder with the same size is larger, simplify the inflation process, and overcome the sealing problem; to solve the above-mentioned background technology Existing in the existing gas blasters: 1. The thickness of the blasting cylinder is 8-60mm, and the density of the steel is high, and the gas blasters generally have the problems of heavy weight, time-consuming and laborious transportation and installation process; 2. The cylinder body The manufacturing process (more than ten steps, each step is time-consuming and laborious) is cumbersome, time-consuming, and the cost of labor and consumables is relatively high; 3. The inflation process is time-consuming; 4. The tube body is easily deformed and the sealing stability is poor; 5. Failure 6. High maintenance cost or difficult maintenance; 7. The mouth of the reusable steel cylinder is easy to scratch and corrode, resulting in air leakage and poor sealing; 8. The stability of the blaster after energy storage is poor; 9. Small gas storage capacity
