Recyclable dacron gas blaster and manufacturing method thereof

Abstract

The invention discloses a recyclable dacron gas blaster and a manufacturing method thereof. The recyclable dacron gas blaster comprises an energy storage device and a gas inflating igniter, the igniter is installed at one end of the energy storage device, and the other end of the igniter is sealed or integrally formed. The recyclable dacron gas blaster is characterized in that the energy storage device is prepared from dacron materials in a cured mode, an energy-releasing inner cover is arranged on the inner layer of the bottom of the energy storage device and provided with an energy releasing window, a pressure-fixed blasting sheet is installed on the energy releasing window in a sealed mode, and the energy-releasing inner cover is made of metal materials. The recyclable dacron gas blaster has the advantages of being small in thickness and weight, convenient to transport and install, easy to manufacture, low in material cost and production cost, high in inflating speed, good in sealing 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 polyester 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 structure used in ...

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 3. The inflation process is time-consuming; 4. The tube body is easily deformed and the sealing stability is poor; 5. The failure rate is high and the yield rate is low; 6. The maintenance cost is high or Maintenance is difficult; 7. The mouth of the reusable steel cylinder is easily scratched and corroded, resulting in air leakage and poor sealing; 8. The stability of the blaster after energy storage is poor; 9. The gas storage capacity is small
