Disposable spherical gas blaster of composite structure and manufacturing method of disposable spherical gas blaster

Abstract

The invention discloses a disposable spherical gas blaster of a composite structure. The disposable spherical gas blaster comprises an energy storage device and an inflating and detonating device. The inflating and detonating device comprises an inflating mechanism and a detonating mechanism which are installed in the energy storage device. The disposable spherical gas blaster is characterized in that the energy storage device is made of a material of which the compressive strength is larger than 345 Mpa, and the energy storage device is of at least two layers of structures and of a spherical structure. The disposable spherical gas blaster of the composite structure has the advantages of being small in thickness, light in weight, convenient to transport and install, easy to manufacture, low in consumable cost and production cost, rapid in inflating, 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 disposable spherical composite structure 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 sto...

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
