The high-explosive primer disclosed by the invention has the advantages that the design is reasonable; the size is small; the use is convenient, safe and reliable; the usage amount of the high-energy primary explosive is reduced; the cost is reduced; and a priming effect which is same as that of a large-charge primer is achieved.
Description
Technical field
The invention belongs to the industrial explosive material production technical field, especially relate to a kind of high quick-fried type detonation tool.
Background technology
Detonation tool is the explosive that is used to ignite desensitized explosive or chamber great explosion, belongs to the relaying explosive.Existing detonation tool is that to adopt with TNT be the main body powder charge basically, and press-fiting or sneak into fusing is cast into behind Tai An or the hexogen cylindric expansion can initiating equipment, and the outsourcing fitted tube adopts the paper web packing mostly, and the plastic barrel of employing manner of packing is also arranged.The detonation under the exciting of detonator of this kind detonation tool is by the output detonation energy insensitiveness main charge in the big gun hole that detonates.Require the explosive payload of detonation tool big; Too peace in the powder charge or hexogen large percentage, otherwise be difficult to guarantee the initiating ability of detonation tool, but too peace, hexogen price are very expensive; Cause the production cost of detonation tool significantly to rise, also brought the safety problem in the detonation tool production process.
Summary of the invention
For addressing the above problem; The purpose of this invention is to provide a kind of reasonable in design, high quick-fried type detonation tool easy to use; It is guaranteeing under the product quality premise; Use less dose just can reach the effect of detonating of big powder charge, reduced too peace or these uses expensive, high explosive of hexogen.
For realizing the foregoing invention purpose, the present invention adopts following technical scheme:
A kind of high quick-fried type detonation tool, it comprises shell body, common priming and high energy priming, the shell body open upper end, lower end closed, the blind end of shell body is provided with two functional holes, is furnished with two positioning pipes over against two functional holes in the shell body; The shell body set inside has an inner housing, and the inner housing lower end is fixed on the shell body bottom, the inner housing open upper end, and two positioning pipes are positioned at the cavity of inner housing, and the high energy priming is contained in the cavity of inner housing, and common priming is contained in the shell body.
The quick-fried type detonation tool of described height; Its shell body lower end is sealed by base plate, and the base plate center offers notch, and notch is provided with the location-plate that shape with it adapts; Location-plate top is stretched in the shell body; Location-plate is provided with two functional holes, and inner housing is positioned at location-plate top, and the shape of cross section of inner housing, size and the shape of cross section of location-plate, big or small identical.
The quick-fried type detonation tool of described height, the height of its inner housing is not more than the shell body height, is not less than the half the of shell body height, and is not less than the height of minimum gauge detonator.
The quick-fried type detonation tool of described height, its high energy priming main component are hexogen or pacify very much.
The quick-fried type detonation tool of described height, its common priming main component is a TNT.
The quick-fried type detonation tool of described height, it is according to weight percent meter, and the content of high energy priming is 20～40%, and the content of common priming is 60～80%.
The quick-fried type detonation tool of described height, its shell body, location-plate, positioning pipe and inner housing are once injection moulding.
Because adopt aforesaid technical scheme, the present invention has following superiority:
The quick-fried type detonation tool of this height, its reasonable in design, volume is little, and is easy to use; Safe and reliable, shell body, location-plate, positioning pipe and inner housing are once injection moulding, and water repelling property is good, inner housing be provided with the cast that is beneficial to priming; When manufacturing a finished product, simplified production technology, increased substantially production efficiency, reduced the use amount of high energy priming; Reduced cost, initiating ability is big, has reached the detonate effect identical with big charge detonates tool.

The specific embodiment
Below through embodiment and combine accompanying drawing that technical scheme of the present invention is done further explain.
Like Fig. 1,2, shown in 3, the quick-fried type detonation tool of height of the present invention, it comprises shell body 1, common priming 2 and high energy priming 4; Shell body 1 open upper end, the lower end is sealed by base plate, and the base plate center offers notch; Be provided with the location-plate 6 that shape with it adapts in the notch, location-plate top is stretched in the shell body, and location-plate is provided with two functional holes; Be furnished with two positioning pipes over against two functional holes in the shell body 1, be respectively first positioning pipe 5, second positioning pipe 7; Shell body 1 set inside has an inner housing 3; The inner housing lower end is fixed on the location-plate 6; The shape of cross section of inner housing, size and the shape of cross section of location-plate, big or small identical, the inner housing open upper end, first positioning pipe 5, second positioning pipe 7 are positioned at the cavity of inner housing 3; High energy priming 4 is contained in the cavity of inner housing 3, and common priming 2 is contained in the shell body 1.
Two above-mentioned positioning pipes are used for two detonators of plug-in mounting or primacord and detonator.
The height of described inner housing is not more than the shell body height, is not less than the half the of shell body height, and is not less than the height of minimum gauge detonator.The height of minimum gauge detonator is 60mm, and therefore, the height of inner housing is not less than 60mm.
