Technical Field

The utility model relates to an electric detonator technical field, concretely relates to long time delay electric detonator is with high energy powder head device that ignites.

Background

The ignition powder head is a main part of an industrial electric detonator, the traditional medicament used by the ignition powder head generally consists of common combustible agent, oxidant, sensitizer and adhesive, the energy output is limited, for example, the common potassium picrate powder head, antimony sulfide is combustible agent, potassium perchlorate is oxidant, potassium picrate is taken as sensitizer, the ignition energy is generally 40-60J, and the ignition powder head can be well matched with a short-delay powder. However, under the condition of long delay, such as the delay agent used by half-second and second delay detonators is relatively insensitive, and can be reliably ignited only by large ignition energy, a relatively sensitive special ignition charge is usually additionally arranged at the front end of the main delay charge.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides a high-energy ignition explosive head device for a long-delay electric detonator, which comprises a tube shell, a high-energy ignition explosive head, a delay body and an initiating explosive, wherein the high-energy ignition explosive head, the delay body and the initiating explosive are arranged in the tube shell;

and the pipe orifice of the pipe shell is also provided with a bayonet plug which is positioned right above the high-energy ignition explosive head.

The technical scheme has the advantages that the high heat value of the metal aluminum powder or the magnesium-aluminum alloy powder is utilized, the combustion heat energy of the ignition explosive head is improved, the ignition capability of the ignition explosive head is enhanced, the electric ignition performance of the original medicament is ensured, and the energy output of the ignition explosive head can be obviously improved.

The high-energy ignition explosive head is a potassium picrate explosive head;

and metal aluminum powder or magnesium aluminum alloy powder is added into the high-energy ignition powder head.

The content of the metal aluminum powder or the magnesium aluminum alloy powder is 20-25%.

The outer wall of the middle part of the pipe shell is provided with an annular groove, the annular groove is horizontally arranged around the outer wall of the pipe shell, and the part of the inner wall of the pipe shell, which corresponds to the annular groove, is inwards convex;

the annular groove and the delay element filling part correspond to each other.

The upper end outer wall of the tube shell is further provided with a plurality of annular sealing imprints, and the bayonet plug is fixedly connected with the tube shell through the annular sealing imprints.

Adopt the beneficial effects of the utility model are that: the high heat value of the metal aluminum powder or the magnesium aluminum alloy powder is utilized to improve the combustion heat energy of the ignition powder head and enhance the ignition capability of the ignition powder head, so that the ignition powder head is in energy matching with the relatively insensitive delay powder body, and reliable ignition can be implemented on the partially insensitive delay powder body, so that a special ignition powder can be omitted, the long-delay detonator structure is simplified, and the manufacturing cost is reduced.
