Description
Technical field
The utility model belongs to technology for detonators, particularly the plumbous delay element detonating primer of a kind of high precision secondary for the mine.
Background technology
The detonating primer that present domestic mine is used generally all is to adopt delay powder structure and the plumbous delay element structure of one-part form.But, also there is the frequent misfire of accuracy delay time poor, high section detonator in this detonator, delay powder contaminated wastewater environment is large and production cost than the high-technology problem, institute
With, can't satisfy the high precision of with all strength promoting in present mine and pursue the needs of hole elementary errors network explosion.Therefore, the utility model designs the plumbous delay element detonating primer of the high precision secondary of using in a kind of mine, not only guaranteed the reliability that detonator is detonated, high section detonator is misfire not, can guarantee that simultaneously detonator presses predefined defer time burn steadily and effect thereof, can satisfy the high precision with all strength promoted in present domestic mine by the needs of hole elementary errors network explosion.
Summary of the invention
The purpose of this utility model is to have the technical problems such as low, the high section detonator of accuracy delay time misfire with detonator in order to solve existing mine, the utility model provide a kind of simple in structure,
Product performance are reliable, defer time is accurate, can reach ± 2%, high section detonator is misfire not, can satisfy the high precision of promoting the use of in present domestic mine and pursue the needs of hole elementary errors network explosion.
The utility model comprises primacord, rubber plug, cap shell, igniting delay element medicament, igniting delay element overcoat, igniting delay element inner sleeve, transitional medicine, main delay element medicament, main delay element overcoat, main delay element inner sleeve, priming explosive, extension shell and explosive etc.Primacord is installed in the rubber plug, rubber plug is arranged in the cap shell, the extension shell is fixed in the cap shell, igniting delay element medicament is contained in the igniting delay element inner sleeve, igniting delay element inner sleeve is made of three semicircle lead pipes, and be pressed in the extension shell by igniting extension extracorporeal set, transitional medicine is arranged between igniting delay element medicament and the main delay element medicament, main delay element medicament is arranged in the main delay element inner sleeve, main delay element inner sleeve is made of three semicircle lead pipes, and be pressed in the extension shell by main extension extracorporeal set, priming explosive is arranged between main delay element medicament and the explosive, and explosive is contained in the bottom in the cap shell.
The utlity model has simple in structure, product performance are reliable, defer time is accurate, can reach ± 2%, high section detonator is the advantage such as misfire not, can satisfy the high precision promoted the use of in present domestic mine by the needs of hole elementary errors network explosion.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1 primacord, 2 rubber plugs, 3 cap shells, 4 igniting delay element medicaments, 5 igniting delay element overcoats, 6 igniting delay element inner sleeves, 7 transitional medicines, 8 main delay element medicaments, 9 main delay element overcoats, 10 main delay element inner sleeves, 11 priming explosives, 12 extension shells, 13 explosives.
Embodiment
As shown in the figure, further specify organization plan of the present utility model and working process below in conjunction with example.
As shown in Figure 1, the plumbous delay element detonating primer of a kind of secondary comprises 1 primacord, rubber plug 2, cap shell 3, igniting delay element medicament 4, igniting delay element overcoat 5, igniting delay element inner sleeve 6, transitional medicine 7, main delay element medicament 8, main delay element overcoat 9, main delay element inner sleeve 10, priming explosive 11, extension shell 12, explosive 13.Primacord 1 is fixed in the rubber plug 2, and rubber plug 2 is arranged in the cap shell 3, and extension shell 12 is fixed in the cap shell 3.Igniting delay element medicament 4 is contained in the igniting delay element inner sleeve 6, and igniting delay element inner sleeve 6 is made of three semicircle lead pipes, and is pressed in the extension shell 12 by igniting delay element overcoat 5 dresses.Transitional medicine 7 is arranged between igniting delay element medicament 4 and the main delay element medicament 8.Main delay element medicament 8 is arranged in the main delay element inner sleeve 10, and main delay element inner sleeve 10 is made of three semicircle lead pipes, and is pressed in the extension shell 12 by main delay element overcoat 9 dresses.Priming explosive 11 is arranged between main delay element medicament 8 and the explosive 13, and explosive 13 is contained in the bottom in the cap shell 3.
Working process of the present utility model is: after primacord 1 is ignited by percussion, lead fire delay element medicament 4, transitional medicine 7 and main delay element medicament 8 again ignite, igniting delay element medicament 4 has the one-way conduction effect, in the transitional medicine 7 that ignites, self then is in a kind of sealed state, main delay element is burnt in a metastable space, thereby the burning that makes main delay element medicament 8 is not subjected to 1 pinch of seal of primacord diameter, what the impact of transitional medicine dose, the defer time of guaranteeing detonator is accurate, pursues the needs of hole elementary errors network explosion so can satisfy the high precision of promoting the use of in present domestic mine.And the advantages such as production cost is low, and is profitable.
