Abstract
The utility model discloses a multi-functional primer which comprises a shell body and an explosive injection shell body accommodated in the shell body, wherein the explosive injection shell body is a hollow cylinder with the top sealed, a space for main charge pouring is formed between the shell body and the explosive injection shell body, a priming system is arranged in an inner cavity of the hollow cylinder, a detonator hole is formed in each of the two sides of the inner cavity, the top of each detonator hole is sealed, a gap is reserved between the top of each detonator hole and the top of the explosive injection shell body, a through hole is formed in the middle of the inner cavity to serve as a wire hole, and an energy gathered hole is formed in the bottom of the explosive injection shell body. According to the multi-functional primer, the paper or plastic shell bodies are used, explosive injection molds are not needed, main charges are directly poured into the shell body to form a finished product instantly, the procedure and time for cooling mold release are saved, production efficiency is effectively improved, unsafe factors of mold release of the product are eliminated fundamentally, and meanwhile, the priming rate of the product is improved, and blasting quality is ensured.
Description
Technical field
The utility model relates to explosion utensil, specifically a kind of initiating source for mine blasting, engineering explosion, water borehole blasting and large outdoors colliery explosion.
Background technology
Detonation tool structure of the prior art is mainly comprised of housing and main charge two parts, product has a detonator hole and a wire guide, when exciting, by the detonator in detonator hole, excites main charge, reaches the whole blast of detonation tool, thereby ignition desensitized explosive, makes it reach very soon steady detonation.
Because detonation tool product requirement has the features such as sensitivity to initiation is high, explosion velocity is high, degree of packing is high, power is large, therefore the main charge of detonation tool product is all to mix with two kinds of high explosives, and main charge itself will have cap-sensitivity, cause product cost very high.Existing detonation tool notes dress product is main charge is cast in the papery housing of metal die cooperation; cause product cooling move back the mould time long, move back mould unsafe factor and increase; serious impact production efficiency, number of molds far can not meet the demand of large-scale production.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Multifunctional primer, and it has the advantages that not need with mould production.
In order to solve the problems of the technologies described above, the utility model has been done further improvement on the basis of existing technology, described Multifunctional primer, comprise housing, also comprise an injection housing being placed in housing, described injection housing is the hollow cylinder of top seal, between housing and injection housing, form the space of cast main charge, inner chamber at hollow cylinder is provided with initiation system, inner chamber both sides are respectively provided with a detonator hole, the top seal in detonator hole and leave space with injection case top, is provided with through hole as wire guide at inner chamber middle part.
Between housing and injection housing, main charge is housed, priming is housed in initiation system, detonator is fixing to be inserted in two detonator holes, by detonator, excites main charge, and wherein any one detonator normal operation, can reach 100% propagation of explosion.During production, do not need to use injection mould, main charge is cast directly in plastic casing and shell, after main charge casting complete, at once become finished product.
As a kind of preferred technical scheme, injection housing bottom is provided with sockets for collecting energy, can play the effect of energy accumulating in the initiation process of product.Sockets for collecting energy is pyramidal structure, loop configuration or cylindrical structural.
In prior art, detonation tool is noted dress product and is main charge is cast on metal die to cooling pattern of moving back mould again, and the utility model is used papery or plastic casing, do not need injection mould, directly main charge is poured into a mould in housing and is at once become finished product.Change primary explosive column into initiation system, the compacting expense that can save primary explosive column on the one hand, also can improve sensitivity to initiation in addition, can improve product percentage of initiation, guarantees blasting quality after use; Can also obviously reduce bursting work cost.
The design application of initiation system, can make the moment excitation energy of detonation tool product be greatly improved, to igniting desensitized explosive, play positive role, not only reach good propagation of explosion, ignition effect, and effectively raise the relevant explosive parameters such as product power, can also be by the adjustment of product main charge formula be reduced to product cost.
In sum, compared with prior art, the utility model realized detonation tool product without mold produce and initiation system in the application of detonation tool inside, and product structure is simple, reasonable in design, explosion transfer performance is good, percentage of initiation, the moment excitation energy that effectively raises product is greatly improved.Thereby the relevant explosive parameters such as power are effectively improved, better improve the detonation propagation reliability of nonel tube of product, can be by the adjustment of product main charge formula be reduced to product cost under the prerequisite that does not reduce its product main performance index; And saved cooling moving back die process and time, effectively enhanced productivity, fundamentally solved the unsafe factor that product moves back mould.
Detonation tool described in the utility model all kinds of desensitized explosives or the enhancing shock wave that detonates that is mainly used in detonating, makes main charge reach very soon steady detonation.It has high density, high-power, good, safe, the free of contamination feature of water-resistance, is applicable to the reliable initiation of all kinds of desensitized explosives under various weather conditions.
