Abstract
The utility model provides a three-hole and high-energy detonating appliance, which is composed of a casing and detonating explosives, wherein a common detonating explosive is cast inside the casing; a high-energy detonating explosive is cast in the common detonating explosive; a detonator inserting hole and a common detonating fuse inserting hole are arranged between the common detonating explosive and the high-energy detonating explosive; a low-energy detonating fuse inserting hole is vertically arranged in the high-energy detonating explosive; the detonator inserting hole is a blind hole of which the lower end has the same altitude as the lower part of the high-energy detonating explosive; the common detonating fuse inserting hole and the low-energy detonating fuse inserting hole are through holes which penetrate from the top of the common detonating explosive to the bottom of the common detonating explosive. The three-hole and high-energy detonating appliance has the characteristics of reasonable design, simple structure, easy manufacturing, good performance of moisture resistance and water resistance, safe storage and transportation, full and tight contact between the explosives and various detonating devices, etc.
Description
Technical field
The utility model relates to a kind of ignition tool, specifically a kind of three hole high energy detonation tools.
Background technology
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.Various the detonating of prior art has at present:
1, the detonation tool that press-fits with powder type explosive, the deficiency of this kind detonation tool be energy can not give full play to and also the dangerous danger of processing 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, adorn the detonation tool of placement detonator in the trinitrotoluene in casting, the deficiency that this kind detonation tool in use exists is because the existence of detonator is very dangerous in production, transportation, storage and use, has 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 the low use of detonation degree is unreliable, mute quick-fried rate height.
5, in casting dress trinitrotoluene, press-fited the detonation tool of medicine core with cap-sensitivity, medicine core composition in the detonation tool 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 detonation tool is that water-resistance is poor, moisture-sensitive.
Summary of the invention
The three hole high energy detonation tools that the purpose of this utility model provides a kind of high explosion velocity high-power high waterproof and has good primacord sensitivity.
The purpose of this utility model realizes in the following manner, casting dress pentaerythritol tetranitrate is the high energy priming composition combined type primary explosive column of primary raw material in the middle of common priming, in order to adapt to detonating of common primacord, low energy fuse and the multiple detonation mode of detonator, in the combined type primary explosive column, be provided with the detonator jack, common primacord jack and the low energy fuse jack that adapt to three kinds of detonation modes respectively.In order to prevent the protection against the tide of priming, add moisture seal lid in the upper end of housing, on seal cover, be provided with and have protection against the tide and easily put in a skylight, and on protection against the tide easily puts in a skylight, stick on and have false proof moistureproof labeling false proof, moistureproof and that easily open.
Description of drawings
Accompanying drawing 2 is the plan structure schematic diagram of three hole high energy detonation tools;
Accompanying drawing 3 is that the A-A of three hole high energy detonation tools is to the section structure schematic diagram.

Explain below doing with reference to Figure of description 1,2,3 pairs of three hole high-energy detonation apparatus of the present utility model.
Three hole high-energy detonation apparatus of the present utility model, its structure is made up of shell 1, priming 2,3, and is common Priming 2 castings are contained among the shell 1, and 3 castings of high energy priming are contained in the centre of common priming 2, common Be vertically installed with detonator jack 6 and common primacord jack 4 between quick-fried medicine 2 and the high energy priming 3, high energy rises Also be vertically installed with low energy fuse jack 5 in the middle of the quick-fried medicine 3, detonator jack 6 is blind hole, its lower end and high energy Priming 3 lower ends are contour, and common primacord jack 4 and low energy fuse jack 5 are through hole, through common Priming 2 tops are to its bottom.
The top of common priming 2 is provided with groove 7, and groove 7 is positioned at detonator jack 6, common primacord jack 4 and the upper end of low energy fuse jack 5.
The upper end of shell 1 is provided with moisture seal lid 8, and the top that the centre of moisture seal lid 8 is positioned at groove 7 is provided with skylight 9, is sealed with moistureproof adhesive label 10 on the skylight.
Embodiment:
Three hole its processing and fabricatings of high energy detonation tool of the present utility model are very simple and convenient, and processing and fabricating both can shown in the by specification accompanying drawing.Processing technology detonation tool processing technology is routinely carried out.Common priming is a trinitrotoluene, and the high energy priming is the mixture of pentaerythritol tetranitrate or pentaerythritol tetranitrate and trinitrotoluene.
The performance of the detonation tool 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
Three hole high energy detonation tools of the present utility model are compared with prior art, have reasonable in design, simple in structure, be easy to processing, moistureproof water-tolerant, storing transportation safety, reliably to reach the medicine physical efficiency abundant, can with characteristics such as various apparatus to cause burstings closely contact, thereby, have good value for applications.
