Abstract
The utility model provides a double-hole and high-energy detonating appliance, which is composed of a casing, an ordinary detonating explosive post, and a detonating sensitive explosive post, wherein the detonating sensitive explosive post is fixed in the casing by the ordinary detonating explosive post and is positioned in the middle of the ordinary detonating explosive post, and an ordinary detonating fuse insertion hole and a low-energy detonating fuse insertion hole are arranged between the ordinary detonating explosive post and the detonating sensitive explosive post. Compared with the prior art, the double-hole and high-energy detonating appliance has the characteristics of reasonable design, simple structure, easy manufacture, good moisture-proof and water-resistant performance, safe and reliable storage and transportation, etc., and the explosive body can be fully and tightly contacted with various detonating devices, so the double-hole and high-energy detonating appliance has good popularization and use value.
Description
Technical field
The utility model relates to a kind of engineering and ignites tool production technology, specifically a kind of diplopore high energy detonation tool.
Technical background
Angle from safety and cost, in large-scale civil engineering, hydroelectric project construction and mining, use the low sensitivity composite explosives of industry more and more widely, the low sensitivity composite explosives of this kind mostly are the pulpous state ammonium nitrate-fuel oil mixture, be difficult to use the detonator direct initiation, must carry out detonation by the relaying detonation tool and just can make the energy of low sensitivity composite explosives obtain bringing into play fully effectively.Present widely used detonation tool mainly contains following several;
1, the detonation tool that press-fits with powder type explosive, replanting the deficiency that detonation tool in use exists is that energy can not be given full play to, and the dangerous danger of processing is big;
2, the detonation tool that forms with trinitrotoluene, pentaerythritol tetranitrate composite explosives casting dress, this kind detonation tool improves the production cost of detonation tool because the content of pentaerythritol tetranitrate is higher.
3, place the detonation tool of detonator in casting dress trinitrotoluene, the deficiency that this kind detonation tool in use exists is the existence owing to detonator, and the production of detonation tool, transportation, storage and use are all dangerous, have very big danger.
4, the detonation tool of primacord is set in casting dress trinitrotoluene, and the deficiency that this kind detonation tool in use exists is that quick-fried sensitivity is low, and it is unreliable to use, mute quick-fried probability height.
5, in casting dress trinitrotoluene, press-fited medicine core with cap-sensitivity, the composition of medicine core is the mixture of trinitrotoluene, pentaerythritol tetranitrate, wherein the content of pentaerythritol tetranitrate is very high, generally be no less than 60%, the deficiency of this kind booster gains is that water-resistance is poor, moisture-sensitive can not be stored for a long time.
Summary of the invention
The diplopore high energy booster gains that the purpose of this utility model provides a kind of high explosion velocity high-power high waterproof and has good primacord sensitivity.
Realize in the following manner during embodiment of the present utility model, adopting pentaerythritol tetranitrate is quick-fried quick powder column, be fixed in the middle of the common primary explosive column, in common primary explosive column intermediate vertical two primacord jacks are set, one of them is common primacord jack, and another is the low energy fuse jack.The center line of two primacord jacks and quick-fried quick powder column cylindrical join.That is to say no matter use which kind of primacord, be inserted in that primacord jack, all can ignite common primary explosive column or quick-fried quick powder column, or ignite two kinds of body of explosive simultaneously and carry out detonation and detonate.
Description of drawings
The purpose of this utility model realizes in the following manner,
Accompanying drawing 1 is the cross-sectional view of diplopore high energy detonation tool;
Accompanying drawing 2 is that the A-A of diplopore high energy detonation tool is to the cross section structure schematic diagram.
Description of reference numerals: shell 1; Common primary explosive column 2; Quick-fried quick powder column 3; Moisture-proof film 4; Common primacord perforation 5; Low energy fuse perforation 6.
Explain below with reference to Figure of description Double-hole high-energy booster grains of the present utility model being done.
Diplopore high-energy detonation apparatus of the present utility model, its structure are by shell 1, common primary explosive column 2, quick-fried quick medicine Post 3, quick-fried quick medicine post 3 are fixed on by common primary explosive column 2 among the shell 1, and quick-fried quick medicine post 3 is positioned at common detonating The centre of medicine post 2 is provided with common primacord perforation 5 and low between common primary explosive column 2 and the quick-fried quick medicine post 3 Can primacord perforation 6.
The center line of common primacord jack 5 and low energy fuse jack 6 and the cylindrical of quick-fried quick medicine post 3 join.
The outer setting of quick-fried quick powder column 3 has plastics moisture-proof film 4.
Embodiment:
Its processing and fabricating of diplopore high energy detonation tool of the present utility model is very simple and convenient, and processing and fabricating both can shown in the by specification accompanying drawing.
The processing technology processing technology of booster gains is routinely carried out.Priming in the quick-fried quick powder column be pentaerythritol tetranitrate or with the mixture of other primings, damp-prrof packing can adopt vacuum overlay film, blown film or soak modes such as film.Select the difference of priming for use according to quick-fried quick powder column, damp-prrof packing can with or need not.Housing can be made with cardboard or blowing.Common primary explosive column is the manufacture craft that is shaped to general detonation tool by die casting in housing.In housing, set in advance stem stem and quick-fried quick powder column during making, then common primary explosive column die casting is advanced in the housing, after the powder column moulding, the stem stem extraction can be formed common primacord perforation and low energy fuse perforation.
The performance of the booster gains that this use is novel is as follows:
Weight: 450 grams/send out
Density: be not less than 1.50g/cm3
Sensitivity to initiation: available No. 6 detonator or 3.6 gram primacord direct initiations;
Water-resistance: can depress in the normal-temperature water of 0.7MPa after the thermoplastic encapsulation and not make moist in 48 hours, detonation property is good.
Explosion velocity: be not less than 7000M/s
Diplopore high energy detonation tool of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, moistureproof water-tolerant, store transportation safety reliably reach the medicine physical efficiency fully with characteristics such as various apparatus to cause burstings closely contact, thereby, have good value for applications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
