Description
Technical Field
A safety detonator without primary explosive utilizes a 'set of explosive charging structure' to convert a high explosive from combustion into detonation to detonate other industrial explosives, mainly solves the problem of high sensitivity of the primary explosive in the conventional detonator, improves the safety of the detonator in the processes of production, transportation and use, and belongs to the technical field of detonator production and use.
Background
The detonator is a detonating element, and the function of the detonator is to generate detonating energy to detonate various high explosive materials. The current detonator generally comprises a shell, initiating explosive, high explosive and the like. The tube shell is generally made of metal materials; lead azide or dinitro azido phenol is generally adopted as the initiating explosive; normally, hexogen (RDX) is used for high explosive charges. When the high explosive is detonated by the initiating explosive, enough initiation explosive is output to detonate other industrial explosives, so that the aim of doing work by explosion is fulfilled.
The sensitivity of the initiating explosive in the detonator is high, and the initiating explosive can be excited to explode by external extremely small energy (such as heat energy and mechanical energy) at normal temperature and normal pressure and instantaneously grow into detonation, namely the initiating explosive is extremely easy to be excited by the external energy to explode. The working principle of the detonator is that the characteristic of the primary explosive is utilized, the primary explosive is excited by small energy (such as sparks), the primary explosive is excited to detonate high explosive (main charge) of the detonator, and then other industrial explosive is further detonated.
Because the sensitivity of the initiating explosive in the detonator is high, the initiating explosive is easy to be excited by external energy to explode, great potential safety hazards are buried in production, transportation, use, storage and other links of the detonator, and many safety accidents are caused by the high sensitivity of the initiating explosive. Therefore, since the 80 s of the last century, manufacturers and related units put a great deal of manpower and material resources into the detonators without the initiating explosive to research and develop, and great research results are obtained. In recent years, there are many domestic patent technologies for detonators without initiating explosive, and most of the technologies abandon traditional initiating explosive (lead azide and dinitro azido phenol) and change the initiating explosive or mixed explosive with lower sensitivity, so that the safety is greatly improved compared with the traditional detonators, but the problem of high sensitivity of the initiating explosive cannot be fundamentally solved, so that the detonators without initiating explosive which are produced at present are only limited in variety and cannot be widely applied.
The safe detonator without the initiating explosive solves the problem of high sensitivity of the initiating explosive in the existing detonator, uses the hexogen (RDX) with lower sensitivity as an excitation unit, and utilizes a charging structure to convert the RDX from combustion to explosion and rapidly grow into the main charging of the detonation initiating detonator.
RDX is a high explosive with relatively stable chemical properties, has low friction and impact sensitivity, is not easy to detonate, and needs to be detonated by a detonator when being used alone. Therefore, the RDX is used for replacing the primary explosive in the 'set charging structure', so that various accidents caused by external impact of the detonator are greatly reduced.
This application has replaced the detonating mode of detonator in former patent with the electric ignition mode on the basis of former patent "a no initiating explosive safety detonator", has optimized former patent structure simultaneously, has further improved the reliability of booster. The patent structurally cancels a check valve (5) in the original design, comprises a valve body (11) and a limit switch (13), and reserves a valve plate (12) in the check valve (5), which is numbered as the valve plate (11); meanwhile, the primary supercharging device is characterized by being made of metal and plastic and having a tubular structure; the two-stage supercharging device in the original patent is divided into a two-stage supercharging device and a three-stage supercharging device; the fire transfer holes (8) in the original patent structure are defined as energy-gathering fire transfer holes.
