Description
Technical field
The present invention relates to a kind of electric cap in initiating equipment field, particularly a kind of Split-assembling-type electric detonator without primary explosive.
Background technology
Along with the continuous application of advanced industrial technology in civil explosive industry, make the performance of initiating equipment more safe and reliable, but with regard to initiating equipment, the insecurity of its essence still exists, as now widely used delay electric detonator and instant electric detonator are subject to the impact of extraneous electricity to be still difficult to overcome, electric cap owing to can produce contingency because the initial explosive sensitivity in detonator is higher in transportation, present stage, increasing technical staff is by changing the performance of primary explosive of detonator, change the charge constitution in detonator, other explosives are selected to substitute priming, and use the technological means such as electric detonator to make initiating equipment, what particularly electric cap and nonpriming material detonator were applied in engineering explosion is more safe and reliable.
At present, in order to improve the stability of electric cap, what domestic and international research was more is electric detonator and electric detonator without primary explosive, electric detonator have security high, be applicable to the advantages such as most of bursting work, as described a kind of electric detonator of antistatic in Chinese patent (patent No.: ZL2014200066786) " Antistatic electronic detonator ", this electric detonator can improve the performance of existing electric detonator antistatic and the problem of existing electric detonator needs solution; For another example Chinese patent (patent No.: ZL2012205324484) " a kind of high voltage withstanding electric detonator " devises a kind of high voltage withstanding electric detonator, its advantage is when preventing high voltage power line breakage electric leakage, detonator payment to a porter snaps on high pressure external power supply, produces contingency.Electric detonator without primary explosive is owing to replacing with the lower explosive with propagation of explosion ability of sensitivity by having the higher priming of sensitivity, performance is more superior to a certain extent, security is higher to make electric cap, as Chinese patent (patent No.: ZL200720095674X) " a kind of detonator without burster " describes the comparatively simple nonpriming material detonator of one, this detonator does not adopt the priming that sensitivity is higher, all drawbacks that customer service adopts priming and produces, this is also the basic characteristics of nonpriming material detonator; For another example at Chinese patent (number of patent application: 2011103215872) in " laser initiation ", laser initiation technology is applied in nonpriming material detonator by this nonpriming material detonator of design, this detonator can high temperature high voltage resistant, so this nonpriming material detonator can be applied in the adverse circumstances such as deep water and high pressure.
Although the advantage of above-mentioned electric detonator and nonpriming material detonator is numerous, but its shortcoming is relatively also more, as when electric detonator shortcoming is explosion, wiring is more loaded down with trivial details, must by special messenger's wiring, be not suitable for the bursting work of metal mine exploitation, production cost and use cost higher, also do not possess the condition promoted the use of at present on a large scale, and existing electric detonator without primary explosive adopts integral structure and charge constitution is single, make the explosive loading amount of electric cap more, and electric igniting assembly in detonator easily in detonator transportation owing to clashing into, the effects such as friction cause external electro ultrafiltration make it ignite and cause blasting cap detonation, in the Chinese patent (patent No.: 2011204809591) describe a kind of split type delay electric detonator in " a kind of Split-assembling-type detonator ", detonator be divided into the section of detonating and ignite section, both are separately produced, storage and transport, substantially reduce harm when detonator occurs unexpected, but it still have employed delay powder, this still has very large instability to a certain extent, therefore, it is high that present stage designs security, superior performance, production cost and the lower detonator of use cost are still urgent problems.
Summary of the invention
Object of the present invention, be to provide a kind of Split-assembling-type electric detonator without primary explosive, its optimal design to electric detonator without primary explosive structure, optimizing and revising charge constitution in electric detonator without primary explosive, to the redesign of strengthening cap, electric detonator without primary explosive is had advantages such as security is high, superior performance, production cost and use cost are lower, solve that existing electric detonator without primary explosive initiating ability is poor, security still lower, production cost and the problem such as use cost is higher.
