Problems solved by technology

[0003] In actual situations, because the detonator may be half-exploded or rejected, in order to improve the reliability of the blast hole, two or even multiple detonators are often connected in parallel in the same blast hole in the industry to reduce the probability of a dumb shot. Although this can improve The reliability of the system, but it doubles the usage of the detonator. In view of this situation, a circular energy output detonator with bidirectional input is designed. Using the characteristics of axial energy output, combined with the energy gathering effect, to increase the radial output energy, it can achieve the characteristics of simultaneous input from both ends and radial output

Embodiment 1

[0020] see figure 1 and image 3 , choose an aluminum shell with a length of 80mm, an outer diameter of 6.8mm and a wall thickness of 0.6mm as the shell (label 2). On the shell, conical grooves with a bottom diameter of 1.2mm and a height of about 0.75 are distributed sequentially from the middle to both sides. Ring (label 10), the distance between adjacent conical rings is 3mm, a total of 11 conical rings, first symmetrically load the main charge in the center position and compact the Taian 0.42g (label, 7, density 1.7g / cm 3 ) or RDX, and then the density of the symmetrical packing is 1.2g / cm 3 Taian each 0.18g (label 6), and then symmetrically packed in bulk Taian each 0.3g (label 5, the density is about 0.88g / cm 3 ), then plug the inner cap (mark 8) to the positioning step (mark 9), and then load the excitation drug (mark 4, the composition is KCLO 3 : RDX mass ratio is 1:1) 0.1g, and finally put the detonating tube tightly wrapped with rubber plugs at both ends, and the...

Embodiment 2

[0022] see figure 1 and Figure 4 , choose the copper shell of the above size as the shell, firstly load the main charge symmetrically in the center to compact Taian 0.42g or RDX, and then load them symmetrically with a density of 1.2g / cm 3 Taian each 0.18g, then symmetrically put in bulk Taian each 0.3g, then plug the inner cap to the positioning step, then fill the excitation drug 0.05g, stuff it into a 4mm long lead wire extension body at one end, and use a closing machine Squeeze and fix it on the shell wall, and finally put the detonating tubes tightly wrapped with rubber plugs at both ends, and then squeeze and fix it tightly on the shell with a closing machine. Using this device, and detonating from both ends at the same time, it was found that 11 rows of dents were made on the steel gasket under it, and the depth of the dents gradually increased from the outside to the inside, and the 3 dents in the middle were obviously deeper than the others. It shows that the devi...

Embodiment 3

[0024] see figure 1 and image 3 , the size is as above, using a copper tube shell, using an emulsion explosive (5% glass microsphere sensitized industrial emulsion matrix) package to wrap the double-head detonator, and the double-head detonator is detonated by inputting signals at the same time. After 10 experiments, it can be detonated smoothly. It shows that its detonation ability meets the industrial detonation requirements.

Abstract

The invention discloses a two-way initiating explosive-free annular energy output detonator. The two-way initiating explosive-free annular energy output detonator comprises a metal pipe shell with an annular energy gathering groove and opened at two ends, two energy input signal channels in the pipe shell, two laser parts and two main charging parts; the two energy input signal channels can be explosion guide pipes, rubber plugs or explosion guide cables or charge input leg wires; and the whole structure is totally and symmetrically filled along the middle of the round pipe. The two-way initiating explosive-free annular energy output detonator can synchronously detonate from two ends, and enhances the detonation initiating reliability; and the two-way initiating explosive-free annular energy output detonator adopts an initiating explosive-free flight piece technology, is safe and reliable, is combined with an annular energy gathering jet principle, and is high in explosion initiating capacity.

Description

technical field [0001] The invention belongs to the technical field of blasting equipment, and in particular relates to a double-head detonator without priming charge and circular energy output. Background technique [0002] Highway excavation, roadway excavation, earthwork blasting, resource mining, urban blasting, and large-scale projects that are related to national interests are inseparable from the use of explosives, and at the same time cannot be separated from the dependence on blasting equipment. From this we can see the demand for blasting equipment in our country Very large, especially the use of detonators is extremely large. These detonators are a considerable fortune. If the use of detonators can be reduced, it will definitely save a lot of expenses. [0003] In actual situations, because the detonator may be half-exploded or rejected, in order to improve the reliability of the blast hole, two or even multiple detonators are often connected in parallel in the sa...
