Description
The utility model relates to a kind of blasting cap, specifically, is a kind of antistatic engineering electrical detonator.
The engineering electrical detonator is a purposes explosive the most widely in engineering explosion and the geological prospecting.Common electrical detonator is generally metal shell, and oral area is sealed with gland, and payment to a porter is welded with scorching hot material by gland and in two payment to a porter, applies priming around scorching hot material, and formations such as priming explosive (or alms giver's medicine) and explosive are housed in its shell.In production, transportation and use because static is once being attached between payment to a porter and the Can, then priming and near meeting cause spark discharge, can cause when serious that priming gets angry and cause unexpected explosion.Therefore, common electrical capsular use range is subjected to restriction to a certain degree.Along with the development of oil, colliery, geological prospecting industry, requirement has been proposed to some extent all on antistatic property for the use of electrical detonator.
Present domestic and international project electrical detonator roughly has following several mode in anlistatig measure, first kind of mode is insulation mode, promptly covers the integral body of metal body with insulant, perhaps encases near igniting head and the igniting head payment to a porter with insulant; Even this mode igniting head and near insulation very thorough, but in the external insulation of metal tube and insufficient, adopt that the effective measures difficulty is very big more; The second way is an electrically conducting manner, promptly gives gland with electroconductibility, as is coated with electric conduction paint, the major part of electrostatic energy is not released by match board head, but the manufacturability of its electro-conductive material is poor, and its resistance value is difficult to grasp; The third mode is the gap discharge formula, i.e. design air discharging gap between payment to a porter in gland and the body is in order to the static of the accumulation of releasing.Because the gap between payment to a porter and body is incomplete same for two payment to a porter, then can produce shunting, its effect is just bad, and the gap adjustment is very difficult; The 4th kind of mode is to get angry part at electrical detonator at introducing the security transformation circuit of being made up of magnet ring etc., and CN871034 75A discloses this design, its objective is in order to isolate the static charge of low-frequency range, and is equipped with the distinctive frequency detonating primer electrical detonator that detonates.But the static charge for higher frequency band is inapplicable, and production cost is increased, and it is complicated that production technique becomes.
The purpose of this utility model, just provide a kind of new antistatic engineering electrical detonator, it can guarantee the performance index of electrical detonator regulation, can prevent the harm that static brings effectively again, and product structure and manufacturing process are simple, and suitable requirement of mass production.
To achieve these goals, technical solution adopted in the utility model is, the structure of this antistatic engineering explosion electrical detonator comprises shell 1, from tube shell bottom pack into successively explosive 2, priming explosive 3 and strengthening cap 4, the shell oral area is equipped with payment to a porter 7 and gland 6, and be connected with glowing filament 8 in the end that payment to a porter feeds shell, and apply priming 9 on glowing filament, and encapsulation is formed with shell.Characteristics of the present utility model are that payment to a porter 7 and the gland 6 in this structure is electrode plugs of making one, gland 6 is electrical conductor, by conductive rubber or conductive engineering plastics manufacturing, resistance range between its payment to a porter and stick harness is between 1k Ω～900K Ω, and the locating sleeve 5 that insulating material is made also is housed between gland 6 and strengthening cap 4.Another characteristics are that priming 9 is compound primings, are made up of lead trinitroresorcinate and industrial Potcrate and pyroxyline lacquer.
The utility model is owing to adopted conductive rubber or the gland of conductive engineering plastics making, make between payment to a porter and the gland and become conductor, and its resistance value is easy to control and adjusts, because the resistance of the bleed-off circuit that this conductor forms is less than the insulation resistance of the compound medicament of igniting, thereby the leakage path when having formed static and various strays and impacting, can prevent the accidental explosion phenomenon that static and various strays bring to electrical detonator effectively.Do the time spent at this detonator of needs, owing to adopt the positioning action of locating sleeve, the compound priming on the electrode plug is instantaneous ignition priming explosive and explosive reliably, forms detonation.This antistatic engineering electrical detonator is compared with traditional electrical detonator, does not have big change on the structure substantially, and production technique is simple, is fit to large batch of suitability for industrialized production.Can satisfy the service requirements in the environment such as geology, exploration, oil, colliery, seismic prospecting.
