Abstract
The utility model relates to a late-model non-primary explosive allowable type electric detonator, which comprises a housing (1), a booster (2), an initiation mechanism (3) and an electric firing mechanism. The utility model is characterized in that the initiation mechanism is arranged between the booster in the housing and the electric firing mechanism. The initiation mechanism is loaded with high explosive or a high explosive mixture. The utility model is of simple structure and process and safe production and use, greatly improving the environmental pollution problem which is caused by the initiation of the detonator. The utility model can be used in a coal mine underground with the danger of gas and in the presence of gas and coal dust explosive and other occasions of industrial blasting.
Description
The utility model relates to a kind of novel electric detonator without primary explosive.This electric cap can use under the coal mine that gas explosion danger is arranged, and also can use under the occasion of other industrial explosion.
In known technology, industrial detonator all is equipped with priming and booster explosive.The impact of priming, friction, flame sensitivity are all very high, make detonator all very dangerous in making, store, transport and using, and explosion accident usually meets accident.Therefore, domestic and international many units have carried out the research of nonpriming material detonator in succession at present, and have obtained certain effect.The research of external nonpriming material detonator mainly concentrates on three aspects.The firstth, the detonation way of improving detonator is to improve its ignition energy.As exploding bridge wire formula, laser type, the various types of nonpriming material detonators of the formula of bouncing.The secondth, adopted strong restrictive structure to impel explosive to change detonation into by burning.As the DDT detonator.The 3rd is synthetic new single chmical compound explosive or existing explosive is improved, and makes its safety, reliable.As the inorganic explosive CP of simple substance.Above-mentioned all nonpriming material detonators mostly are complex structure, and cost is expensive and can't adopt in a large number aborning.Domestic No. 89210088.5 patent disclosures a kind of safety of coal mines type electric detonator without primary explosive, this detonator need design special detonation element, complex process, cost height.
The purpose of this utility model is that the structure of improving above-mentioned electric cap is formed, and provides a kind of structure, technology simple, and the Permitted Detonator for Coal Mining electric detonator without primary explosive of anti-gas and dust explosion performance is arranged.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1 is housing, and 2 is booster explosive, and 3 is fuse mechanism, and 4 is ignition charge, and 5 is plastic plug, and 6 are payment to a porter, and 7 is flash hole, and 8 is strengthening cap.
The electric cap that the utility model relates to, it mainly improves is priming or the detonation element of having cancelled in the traditional electrical detonator, is replaced by fuse mechanism 3 ". Its concrete technical scheme is that it is made up of electric cap housing 1, booster explosive 2, fuse mechanism 3 and electric firing mechanism. The bottom dress booster explosive 2 of housing 1, top dress electric firing mechanism. Be provided with fuse mechanism 3 above the powder column of housing 1 interior booster explosive 2 and between the electric firing mechanism, its housing 1 loads quick-fried mechanism 3 places and is the narrow garden cylindrical shell that closes up. Fuse mechanism 3 finger powder charges are high explosive or high explosive mixture. High explosive can be hexogen, also can be other high explosive, also can add an amount of auxiliary thing such as the chlorate etc. of adding in high explosive. Electric firing mechanism is the broad-mouthed receptacle for holding liquid shape strengthening cap 8 in-built ignition charges 4 with flash hole 7, and payment to a porter 6 is directly inserted in the ignition charge 4, and seals with plastic plug 5, and plastic plug 5 is fixing with clipping machine and detonator shell. Like this, lighted the powder charge of fuse mechanism 3 by electric firing mechanism when electric current after, make it change detonation into by burning, the booster explosive 2 of last detonating primer housing 1 bottom causes blasting cap detonation.
The utility model structure, technology are all simpler, and cost is lower, and production and use are all very safe, and the problem of environmental pollution that is caused by priming is also had improvement greatly.The utility model can use under the coal mine that gas and dust explosion danger is arranged, and also can be used for other industrial explosion occasion.
Claims (1)
- A kind of Permitted Detonator for Coal Mining electric detonator without primary explosive, comprise electric cap housing 1, booster explosive 2 and electric firing mechanism, the bottom dress booster explosive 2 of housing 1, top dress electric firing mechanism, it is characterized in that above the powder column of booster explosive 2 in housing 1 and be provided with fuse mechanism 3 between the electric firing mechanism, fuse mechanism 3 refers to that powder charge is high explosive or high explosive mixture, and its housing 1 dress fuse mechanism 3 places are the narrow garden cylindrical shell that closes up; Electric firing mechanism is dress ignition charge 4 in the broad-mouthed receptacle for holding liquid shape strengthening cap 8 of band flash hole 7, and payment to a porter 6 is directly inserted in the ignition charge 4, seals with plastic plug 5.
