Problems solved by technology

It is required that the detonator has a large amount of charge, and the proportion of Taian or RDX in the charge is relatively large, otherwise it is difficult to ensure that the detonator has the detonation sensitivity of the detonator, resulting in a substantial increase in the production cost of the detonator, and also brings Safety Issues During Production

Embodiment Construction

[0011] A new type of energy-concentrating detonator, which is provided with a detonator 3 on the central axis near the detonation point of the through hole 2 of the detonator detonator; the detonator is an independent explosive unit, which is installed in the In a capsule and sealed; the charge of the detonator is not less than 10g / piece; 3 to 8 arc-shaped closed energy-gathering semicircular grooves 5 are evenly distributed on the outer wall of the detonator, and the grooves are closed In the outer wall of the packaging tube, the groove is filled with air, which is the growth space for the detonation wave generated during the detonation of the detonator and the energy-gathering jet 7 of the reaction product 6 .

[0012] Such as figure 1 , the detonator is inserted into the detonator from the through hole 2, pierced through the other end, and then inserted back into the detonator hole 4, and the detonator can be put into the detonated blast hole by tightening the detonating wi...

Abstract

The invention discloses a novel energy collecting primer. A priming body is arranged at a central axis position close to a priming point of a detonator hole of the primer, is an independent explosive unit, is arranged in a capsule by using penthrite or hexogen and sealed; charge quantity of each priming body is not less than 10g; 3 to 8 cambered closed energy collecting semicircular grooves are uniformly distributed on the outer wall of the primer; and the grooves are closed in the outer wall of a packaging drum. The invention has the advantages that: a low-charge primer has the same priming effect as a high-charge primer, the charge quantity is obviously reduced, and cost is also reduced.

Description

technical field [0001] The invention belongs to the technical field of the product structure of the detonator of civil explosive materials. Background technique [0002] Existing detonators basically adopt TNT as the main charge, press-packed or mixed with Taian or Hexogold and then melted and cast into a columnar energy-expanding detonator. Most of the outer packaging tubes are packed in paper tubes, and some Packaging in plastic tubes. The detonator is detonated under the excitation of the detonator, and the insensitive main charge in the gun hole can be detonated by the output detonation. It is required that the detonator has a large amount of charge, and the proportion of Taian or RDX in the charge is relatively large, otherwise it is difficult to ensure that the detonator has the detonation sensitivity of the detonator, resulting in a substantial increase in the production cost of the detonator, and also brings Safety issues in the production process.
