High-safety initiating-explosive-free basic detonator

Abstract

The invention relates to the technical field of civil explosives, in particular to a high-safety initiating-explosive-free basic detonator. The high-safety initiating-explosive-free basic detonator comprises a basic detonator shell, a high explosive is pressed on the inner wall of the bottom of the basic detonator shell, pentaerythrite tetranitrate I is pressed at the position, over the high explosive, inside the basic detonator shell, pentaerythrite tetranitrate II is pressed at the position, over the pentaerythrite tetranitrate I, inside the basic detonator shell, a reinforcing cap attachedto the top of the pentaerythrite tetranitrate II is connected to the inner side wall of the basic detonator shell in a clamped mode, pentaerythrite tetranitrate III is pressed inside the reinforcing cap, and a boss is arranged at the position, close to the reinforcing cap, of the inner side wall of the basic detonator shell. The high-safety initiating-explosive-free basic detonator has the beneficial effects that the pentaerythrite tetranitrate I, the pentaerythrite tetranitrate II and the pentaerythrite tetranitrate III are adopted as explosive agents, an initiating explosive with high sensitivity is not adopted, the detonation growth period of the initiating explosive with high sensitivity is short, detonation is fast, and compared with the initiating explosive with high sensitivity, thedetonation period of the pentaerythrite tetranitrate is long, the effects of being safer, more practical and more reliable are achieved, and the production process of the pentaerythrite tetranitrateis more environment-friendly compared with the production process of the initiating explosive with high sensitivity.

Description

technical field [0001] The invention relates to the technical field of civil explosives, in particular to a high-safety primary detonator without primary explosives. Background technique [0002] Most detonators use primary explosives, and their structure includes: shell, reinforced cap, etc. The shell is cylindrical. The charge structure and ignition method of the basic detonator are basically consistent. With the maturity of detonator technology, people are more concerned about the safety performance of detonators. The requirements are also getting higher and higher. [0003] Chinese Patent No. CN201053852Y provides a new type of non-priming detonator, including: a shell, a reinforced cap, the middle and upper part of the inner cavity of the outer shell has a downward taper, and the middle and lower parts of the inner cavity are provided with a raised platform. The upper support is provided with a bowl-shaped reinforced cap, under the reinforced cap, false explosives and ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of high-safety type non-primer base detonator, to solve the existing base detonator proposed in the above-mentioned background technology all is to use the higher detonator of sensitivity as explosive, because the higher detonator of sensitivity The growth period is short, the detonation is fast, and the high-sensitivity primary explosive produces a large amount of waste water, strong coloring power, and serious heavy metal pollution in the pharmaceutical process, which does not conform to the development direction of my country's environmental protection. At the same time, the existing detonator In the process of production, storage and transportation, there are many hidden dangers
