Abstract

The invention provides a reinforced cap type industrial detonator without initiating explosive, belonging to initiating equipment for engineering blasting. The invention is characterized in that: the traditional ignition powder is added with a desensitizer and a catalyst to form the ignition powder to replace the initiating powder, so that the detonator without the initiating powder is simple in structure and suitable for being produced by the existing detonator production line. The detonation powder has large detonation impulse energy and can rapidly realize detonation to detonation under the condition of not strong constraint. The detonator of the invention can be ignited and detonated by a detonating tube, an electric ignition head, a detonating cord and a delay element, has reliable detonation and good stability, and solves the two defects of environmental pollution and unsafety of the traditional detonator.

Description

Cap type detonator having no igniter

The invention belongs to the initiating equipment that engineering explosion is used.

There are two serious defectives in traditional industrial detonator because of priming explosive is housed.The one, that priming explosive is discharged in industrial production is mercurous in a large number, the poisonous waste water of lead or phenols, causes environmental pollution; The 2nd, priming explosive brings danger to capsular manufacturing, transportation, storage and use.The industrial detonator using no priming charge of present research is mainly started with from two aspects of elementary powder charge of detonator structure and replacement priming explosive and is solved detonator transfers detonation to from burning problem.Aspect detonator structure,, increase outer edge constraint condition to improve structure, improve igniting towards reaching the purpose that causes high explosive detonation, as exploding bridge wire formula nonpriming material detonator, flying-piece auget without detonating agent etc., this class detonator structure complexity, the production cost height fails to realize civilian industryization.The described double-cap industrial detonator using no priming charge of CN87212500U is respectively to withhold a strengthening cap on alms giver's medicine of transitional medicine and non-priming.This detonator assembly technology is complicated, need increase manufacturing facilities the cost height.The described single cap type non-priming of CN90211681.9U short delay detonator is that a strengthening cap is set between transitional medicine and alms giver's medicine.This detonator alms giver medicine is the top that is seated in strengthening cap, the phenomenon of spreading pesticides in transportation with in using, and the reason of nonconforming because of vibratory test in addition and security aspect, this detonator can not directly be used the safety fuse igniting blasting.Aspect the elementary powder charge that replaces priming explosive many inventions are being arranged also at present.The described safe commercial detonator of CN85101936A is made up of a shell and inner casing, has loaded high explosive and cumulative part with accelerate combustion tendency in the inner casing, and the two constitutes a detonation element, has replaced priming explosive.Such elementary powder charge is under stronger constraint, though its initiation power can satisfy the requirement of nonpriming material detonator, but flame sensitivity is low, be difficult for being ignited by seed elements such as safety fuse, delay powders, need to remedy with priming charge, and need inner casing of compacting and power-assembling component earlier, and this has just increased the filling number of times, and current product line need be transformed.The described nonpriming material detonator of CN86102717A, CN87104857.4A, be to replace priming explosive with priming charge, generally form by oxidizer such as combustible agent plumbous rhodanate, lead ferrocyanide, boron, silicon, the elementary powder charge flame sensitivity of this class height, be easy to igniting, but blasting energy is less, and structurally needing elementary powder charge and changeing quick-fried medicine has stronger constraint, and assembly technology is also complicated.

The object of the present invention is to provide a kind of mechanical sensitivity lower, flame sensitivity is good, blasting energy is than the big priming charge of blasting energy of existing all kinds of priming charges, and guaranteeing under the reliable situation of detonation, provide a kind of simple in structure, assembly technology is identical with existing industrial detonator technology, and existing detonator production line is not made the just producible nonpriming material detonator of any transformation.

Nonpriming material detonator of the present invention comprises: housing 1, strengthening cap 2, priming charge 3, the quick-fried medicine 4 of commentaries on classics, main charge 5, bottom japanning 6, damp-proof membranes 7, bonding crack japanning 8, it is characterized in that at traditional priming charge, promptly at oxygenant: potassium perchlorate, tri-lead tetroxide or barium peroxide and reductive agent: add deterrent and catalyzer in lead ferrocyanide, plumbous rhodanate or boron powder, the zirconium powder, form priming charge, replace priming explosive with priming charge.Said deterrent is stearate or graphite, and catalyzer is sodium aluminum fluoride, carbon, stablize red phosphorus or manganese, the metallic compound of copper, cobalt, nickel.Deterrent and the catalyzer content in priming charge is 0.1～10%.The present invention is achieved in that the main charge 5 of at first packing into successively, changes quick-fried medicine 4 in housing 1, priming charge 3, above priming charge 3, directly withhold again one long be 6～10 millimeters strengthening cap 2 and japanning.The present invention adopts priming charge 3 to replace priming explosive as the elementary powder charge of capsular, because the priming charge blasting energy is big, so when priming charge 3 is exported bigger blasting energy (reduced blast situation) after lighting, making changes quick-fried medicine 4 rapid deflagration to detonation transition of realizing under the not too strong constraint of strengthening cap 2, the low velocity detonation that changes quick-fried medicine 4 causes that further main charge 5 detonations grow into the high speed steady detonation, makes the externally big detonation striking energy of output of detonator.

The present invention compared with prior art, one of its distinguishing feature is simple in structure, comprehensive cost is low, charge process is identical with existing detonator, existing detonator production line does not make any changes and just can produce, plain detonator of the present invention has only powder charge secondary suppression process three times; Two of characteristics are that the priming charge blasting energy is big, have guaranteed capsular detonation reliability, and through verification experimental verification, priming charge consistency and security are all qualified; Three of characteristics are that priming charge is to mix the tobacco curing gunpowder, change quick-fried medicine and are the violent quick-fried medicine without any physics and chemical process, and wastewater flow rate seldom in the manufacturing; Four of characteristics, available multiple mode is lighted a fire, and constitutes the non-priming plain detonator, wink is sent out and delay electric detonator and sending out in wink and the Nonel detonator of delaying.The action time of the non-priming short electric detonator that the present invention constitutes, (from being energized to detonation output) was 1 millisecond～8 milliseconds, was suitable for assembling the extension of high-precision detonator.
