The initiating section and the detonation section are designed in a split manner, and the two parts are separated in the production, transportation and storage processes, so that the problem that a major accident is easy to cause by the integration of the two sections of an existing detonator can be well solved, when the detonator is detonated, after the two sections are assembled together, the split assembled detonator can be used like a traditional detonator, and the initiating function is stable.
Description
Technical field
The present invention relates to ignition equipment, particularly a kind of junction is with the Split-assembling-type detonator of troughs for collecting energy.
Background technology
Detonator is widely used as the main apparatus to cause bursting of explosive, its primary structure is in Can, bury high explosive, priming, delay powder and medicine head successively underground, medicine head connects payment to a porter and draws Can, wherein priming, delay powder and medicine head are as priming device, and high explosive is the primer of detonator, medicine head is lighted by payment to a porter energising during use, medicine head lights delay powder, priming lighted by delay powder, priming is ignited and is produced detonation wave, detonation wave propagates into high explosive and makes high explosive detonating primer, existing detonator is integral type, its high explosive, priming, delay powder and medicine head are placed in same shell simultaneously, in production, can because clash in the process of transport and storage, the safe Release Sensitivity Problem such as electrostatic or friction and cause security incident, when electrostatic breakdown metal shell, the high explosive of the high quick-fried energy of low sensitivity in the priming detonating primer of the low quick-fried energy of high sensitivity can be made to cause huge personnel, property loss.That is, priming in detonator is very easily detonated, but the energy detonated is low especially, if be the priming blast in detonator, power is very little, very little to the injury of people, can not cause large loss, the power of high explosive is very large, but it is not easily revealed, only have the external world to give when sizable energy stimulates it just can be made to explode, if priming and high explosive effect, heavy losses can be caused by the very large energy of abrupt release.
Summary of the invention
The object of the present invention is to provide a kind of Split-assembling-type detonator of junction with troughs for collecting energy of the function-stable that detonates, be intended to solve traditional detonator problem that risk factor is high when producing, transporting and storing.
The object of the invention is to be achieved by the following technical programs, a kind of junction is with the Split-assembling-type detonator of troughs for collecting energy, comprise shell and bury high explosive, priming, delay powder and the medicine head in shell underground, medicine head connects payment to a porter fairlead shell, wherein priming, delay powder and medicine head are as the section of detonating, high explosive is as the ignition section of detonator, the section of detonating is embedded in two shells be separated with ignition section respectively, be provided with connection fit structure between two separation shells, it is characterized in that: described connection fit structure place is with troughs for collecting energy.
Connection fit structure between described two separation shells is for being threaded.
The present invention is on the basis of original application for a patent for invention, carry out perfect to a kind of Split-assembling-type detonator, take the section of detonating and ignite section split design, in production, transport is separated with two parts in storage process, solve the problem that existing detonator two sections of one easily cause major accident well, when designing, troughs for collecting energy is provided with in the junction of the section of detonating and ignition section, the energy of the section of detonating can be assembled better, and then better ignite the high explosive of section, guarantee stable detonating, employ just the same with traditional detonator after two sections of assembly and connections when igniting, detonate function-stable.

Detailed description of the invention
As shown in Figure 1, detonator provided by the present invention is divided into the section of detonating and ignites section, produce, transport and two-phase seperation in storage process, during ignition, two sections connect use, connected mode is taked to be threaded, the section of detonating comprises payment to a porter 1, bayonet socket plug 2, medicine head 3, delay powder 4, priming 5, inner casing 7 and shell 8, ignite section to be made up of shell 9 and high explosive 6, delay powder 4 and priming 5 are first compressed in inner casing 7, then inner casing 7 is loaded in shell 8, the end of payment to a porter 1 connects medicine head 3, payment to a porter 1 is set in bayonet socket plug 2, finally bayonet socket plug 2 is loaded in shell 8, then bayonet socket compacting is reinforced, shown in composition graphs 2, the lower end of shell 8 is provided with external screw thread 10 with ignition section junction, shown in composition graphs 3, high explosive 6 is pressed into column in advance, a powder charge and two times powder charges are pressed into solid standard body respectively, load shell 9 inner sealing, shell 9 epimere inwall is furnished with the internal thread 12 being connected with external screw thread 10 and coordinating.Shown in composition graphs 2 and Fig. 3, the section of detonating and ignite section place with troughs for collecting energy 13.Shown in composition graphs 1, in the section of detonating and ignition section threaded connection place, PVC tape 11 can be used to carry out consolidation process to it.Shell 8,9 adopts nonmetallic materials (as safety glass) to be processed to form the thick hard shell of about 2mm, and its hardness meets the tying requirements of detonator, guarantees the binding character of detonator, crosses thin then binding character not strong, blocked up, affects the Detonation Initiation Effect of detonator.
The present invention takes to produce, transport and two-phase seperation in storage process, during ignition, two sections connect use, guarantee binding character, make detonator proper detonation, risk factor high, destructive strong safety problem when solving the high explosive co-production of the priming of the low quick-fried energy of high sensitivity in existing detonator and the high quick-fried energy of low sensitivity, transport, storage; Better and the relatively cheap nonmetallic materials shell of resistance to voltage is used to replace traditional metal shell, improve security, save production cost, and non-metal shell comparatively metal shell compare, it is antistatic, strays, thunder and lightning, electromagnetic wave and high-frequency signal ability significantly improve, and improves intrinsic safety.
The section of detonating is used for detonating the high explosive pranged in powder column, reach the stable ignition effect of detonator, when detonating, medicine head is lighted in payment to a porter energising, medicine head produces focus combustion delay powder, and priming lighted by delay powder, and priming detonation produces detonation wave, in conjunction with the cumulative action of troughs for collecting energy, better make detonation wave propagate into high explosive and make high explosive detonating primer.
Above-described embodiment is only better embodiment of the present invention; describe technical conceive of the present invention and essential implementation in detail; not that protection scope of the present invention is limited; all any simple modification of doing according to Spirit Essence of the present invention and equivalent structure transformation or modification, all should be encompassed within protection scope of the present invention.
