Background technology
With carrying forward vigorously for civil explosive industry safety management dynamics and engineering explosion technology, the popularization of mixed explosive has turned into
The dominant direction of following blasting engineering, either underground mixed explosive or general mixed explosive, sensitivity to initiation is compared with conventional roll
Blasting charge is presented and is decreased obviously, and this is also beneficial to the safety of transport and powder charge process, therefore the deep hole blasting of general large-scale mine is adopted
Detonated with detonation tool.
Indivedual mines are made detonating material using 8# detonators and Explosive roll and detonated, and blasting cap detonation occurs once in a while and fries
The situation that medicine miss-fires, detonation reliability is poor, and larger potential safety hazard is brought to follow-up blind big gun disposal.
Though in addition, solving detonation integrity problem using detonation tool detonation, complicated, water repelling property is limited, into
This height, manufacturing process is relatively cumbersome, and its main charge melts note using TNT, and production process toxicity is big, easily causes human injury and environment
Pollution.
The content of the invention
The purpose of the present invention, which is that, provides a kind of high-power priming device, to solve the above problems.
To achieve these goals, the technical solution adopted by the present invention is such：A kind of high-power priming device, including
Shell, prang powder column, inert filler and detonator or primacord insertion apparatus, wherein, it is described prang powder column, inert filler and
Detonator or primacord insertion apparatus are respectively positioned in shell, and the powder column that prangs is located at the outer casing bottom, the inert filler
Positioned at pranging above powder column, detonator or the primacord insertion apparatus be located above inert filler and insert inert filler and
Powder column is pranged, the centre of detonator or the primacord insertion apparatus is provided with patchhole.
In use, detonator or primacord are inserted into detonator or primacord insertion apparatus, detonator or primacord are fixed
In case surface, then the priming device of the present invention is fitted into blasthole and is in close contact with explosive, you can realizes reliable initiation
Purpose.
As preferable technical scheme：The material of the shell is PP or modified plastics or metal material.
The color of shell is preferably sky blue or other eye-catching colors, and surface of shell is preferably printed on enterprise's mark and product
Title.
As preferable technical scheme：The material for pranging powder column is RDX or pacified very much.
As preferable technical scheme：For the powder column that prangs for cylinder, external diameter is 30~35mm, highly for 10~
40mm, centre are provided with through hole.
As preferable technical scheme：The density for pranging powder column is not less than 1.5g/cm3, dose is 12~100g/
Set.Pranging the dose of powder column can be adjusted according to different blasting engineerings.
As preferable technical scheme：The material of the inert filler is foam.It can also be or other are beneficial to filling
Inert material, the purpose for setting inert filler is that effect is fixed to prang powder column and increase counterweight.
As preferable technical scheme：The material of detonator or the primacord insertion apparatus is PP or modified plastics or gold
Belong to material.
As preferable technical scheme：The diameter of the patchhole of detonator or the primacord insertion apparatus and 8# detonators are led
Quick-fried rope matching.
The present apparatus using high density due to pranging powder column (1.55 g/cm3More than, preferably g/cm3-1.65g/cm3), it is real
Explosion velocity is tested in more than 6500m/s in border, and the raw material ammonium nitrate for the commercial explosive that can detonate, and ammonium nitrate is shaped as doing
State, powdery or granular, therefore there is excellent detonation performance；Reach for the percentage of initiation of the raw material ammonium nitrate of commercial explosive
More than 99%, there is excellent detonation reliability, and use in general detonation tool, can not reliable initiation commercial explosive raw material
Ammonium nitrate, therefore the priming device that the present invention develops has obvious high-power attribute.
Further, since shell of the present invention preferably uses high-quality plastics, and has certain thickness and excellent toughness, just
Under normal operating condition and blasting environment, sharp object（Such as rubble corner angle in blasthole）Shell will not be caused to damage, in addition
Shell and detonator or primacord insertion apparatus no-float, and preferably scribble waterproof Instant cement in both binding sites（Such as modification
Epoxy resin）, therefore water repelling property can be controllable.
Compared with prior art, the advantage of the invention is that：The priming device of the present invention is simple in construction, and assembling is quick, makes
With conveniently, various outdoor and underground explosion engineering can be widely applied for；Manufacturing cost is cheap, and water repelling property is excellent, manufacturing process
Safety non-pollution, traditional detonation tool can be substituted, there are good market prospects.
