Problems solved by technology

Through practice, the existing non-priming detonators, such as: the patent No. 89210088.5 "coal mine safety type non-priming explosive detonator", the patent No. 86200656 "nonel type non-priming explosive detonator", the patent No. 90105695.2 The "Inner Cap Type Industrial Detonator Without Detonator", etc., have the following deficiencies: ① the assembly process is complicated
④ The same type of detonator has a large amount of charge
⑤ Insufficient detonation energy of non-electric detonator with simple structure
⑥ It is unsafe to use electric detonation detonator tube
⑦ high cost
⑧The detonation system of non-electric detonator without detonator is not perfect enough

Embodiment 1

[0038] A detonator 11 with iron shell 1 of Ф10mm and length of 80mm manufactured according to the structure of Fig. 1 without priming charge is used in the energy gathering hole 7 at the bottom: 7.2 parts of aluminum powder, 72.8 parts of high explosive and 20 parts of black powder, the mixing density is 1.2g / cm 3 of mixed explosive pads are compacted flat. A plastic detonating tube 5 with an average length of 1.5m is used, and a flared opening 10 is set on one side of one end, the T-shaped plug 9 is replaced by a tack, the longitudinal elastic member 8 is an elastic rubber strip, and the horizontal fixing member is used. 12 Use general ropes. Plug the tack on the hole at the end of the detonating tube 5, and use an elastic rubber strip to tightly hoop the middle of the outside. The said check valve 13. Insert the plastic detonating tube 5 with the end of the check valve 13 into the tube shell 1 that has been cushioned with mixed explosives in the energy gathering hole 7, a...

Embodiment 2

[0040] The non-priming charge detonator manufactured by the structure of Fig. 1, as the detonator made in Example 1, wherein the composition weight ratio of the mixed explosive is: 5~15 parts of aluminum powder, 65~80 parts of high explosive and 15~15 parts of black powder 25 parts, the density is 0.7~1.2g / cm 3 . If a mixed powder ratio is: 7.2 parts of aluminum powder, 72.8 parts of dynamite and 20 parts of black powder, the mixed density is 0.9g / cm 3 The other mixing ratio is: 7.7 parts of aluminum powder, 77.3 parts of high explosive and 15 parts of black powder, and the mixing density is 1g / cm 3 When using a fire detonator to detonate two detonators at the same time, both detonators can be detonated, but there are differences in the sound and light source of the detonation of the two detonators.

Embodiment 3

[0042] A non-electric type detonation system without primer detonator formed according to Figure 3, its firing device 14 is a fire detonator, and the detonating element is a plastic detonator 15 and one-to-one joints 16, one-to-two joints 17 and One is connected to the three-joint 18 branch connection structure, and the working end element is made of a plastic detonator type non-priming charge detonator 11 or a fuse (which replaces the fuse type non-priming charge detonator) and other non-electric type non-priming charge detonators. After connection and detonation, all non-electric detonators without detonators are detonated.

Abstract

The invention provides a detonating tube type non-priming detonator and a non-electric detonating connecting method and is characterized in that: a detonator comprises a detonator shell and a detonating tube for inserting to the detonator shell and also comprises a tapered energy collecting hole arranged on the bottom of the detonator shell, a back valve arranged on the bottom of the detonating tube which is inserted to the detonator shell and an explosive mixture with high explosive which is filled among the energy collecting hole, the inner side of the detonator shell and the plastic detonating tube. A detonating system comprises a firing gear and a detonating tube; one end of the detonating tube is connected with the firing gear; the detonating system also comprises a one-to-one joint, a one-to-two joint and a one-to-three joint which are formed by that the detonating tube is connected with each branch detonating tubes; each joint is connected with each branch detonating tube to form a detonating tube branch with different level; the bottom end of each branch detonating tube of the bottom level is connected with the detonator. The non-priming detonator of the invention avoids unsafe factors of pollution, transportation, processing and use and has good detonating system performance and convenient use. The invention is suitable for various detonating operations and salute firing.

Description

technical field [0001] The invention relates to a blasting device, in particular to a detonating detonator and an detonating system thereof. Background technique [0002] Detonating detonators are widely used in various fields as a point explosion source. It is not only used as a point explosion source in the military, but also in mining, stone processing, engineering foundation excavation, demolition of old buildings (structures), blasting forming, It is also used as a point explosion source for civilian use such as blasting processing and salute casting. The point source detonators currently used in the general civilian blasting field, such as electric detonators, fire detonators, non-electric millisecond detonators, etc. The detonator is usually equipped with a detonating charge and a high explosive, and the detonating charge has a high explosion sensitivity, which is also called a sensitive explosive. The process of non-conductive detonator used for blasting is general...
