A top cover 2 is provided at the top of the housing 1. There is a partition 3 at the middle position of the inner cavity of the housing 1. A first charge area 4 and a second charge area 5 are formed between the partition 3 and the housing 1. The first charge area 4 is located at the top of the second charge area 5. A through wire tube 6, a stepped detonating cord tube 7 and a detonator blind tube 8 are arranged on the surface of the partition 3. The two ends of the through wire tube 6, the stepped detonating cord tube 7 and the detonator blind tube 8 penetrate through the partition 3 and extend into the interiors of the first charge area 4 and the second charge area 5 respectively. A conical shaped charge cavity 9 is provided at the bottom of the inner cavity of the housing 1. Two wire clamping grooves 10 and one wire clamping groove 10 are integrally formed respectively at the bottom of the housing 1 and below the through wire tube 6 and below the detonator blind tube 8. The housing 1 is of a cylindrical structure and is made of integrally formed polyamide material. The top cover 2 is adapted to the top structure of the housing 1. The through wire tube 6 and the detonator blind tube 8 are both cylindrical tubes. The stepped detonating cord tube 7 is composed of an upper thin tube and a lower thick tube that are interconnected. The partition 3 is of a circular structure, and the outer wall of the partition 3 fits the inner wall of the housing 1. The partition 3 is made of cardboard or plastic board.

[0025] Specifically, in this embodiment, the functions of each structure are as follows:

[0026] The housing 1 of the detonator is of a cylindrical structure and is made of integrally formed polyamide material, which can effectively restrain the radial load generated during explosion, so that the detonation wave is transmitted axially;

[0027] The diameter of the partition 3 is slightly lower than the inner diameter of the housing 1, and it is made of materials such as paper or plastic with a thickness of 1 mm - 3 mm. Its function is to form a partition effect during the detonation wave transmission process, enhance the shock wave energy of the detonator. The partition 3 divides the housing 1 into a first charge area 4 and a second charge area 5. Among them, the first charge area 4 is a mixture of retired and disassembled and recycled TNT or TNT - RDX explosive, retired propellant grains or retired propellant grains, which is used to improve the initiation sensitivity and ensure the initiation reliability of the detonator. The second charge area 5 is retired and disassembled and recycled TNT or TNT - RDX explosive, which is used to form a stable shock wave jet, enhance the power of the detonator, and further enhance the work - doing ability of the detonator;

[0028] The conical shaped charge cavity 9 at the bottom of the housing 1 is integrally formed inside the detonator housing 1, and its taper is 15 degrees to 150 degrees. Its function is that after the injection charge explodes, the detonation wave forms a shaped charge effect through the conical structure design, enhancing the detonation wave energy and penetration depth, thereby improving the power of the detonator;

[0029] The through wire tube 6 is a cylindrical tube, and its function is to form a detonator through - hole to facilitate the reliable passage of the detonator and the detonator wire. There are two wire clamping grooves 10 at the lower end, and the groove width is 2 mm - 3 mm. Its function is to clamp the detonator wire passing through the through wire tube 6 to prevent the detonator wire from falling off during the charge - loading downward process of the detonator;

[0030] The function of the detonator blind tube 8 is to form a detonator groove for assembling detonators. A wire clamping groove 10 is provided at the lower end. The groove width is 2mm-3mm. The function of the detonator blind tube 8 is to clamp the detonator wire of the assembled detonator to prevent the detonator from falling off downwards during use, thereby improving the detonation reliability of the detonator.

[0031] The stepped detonating cord tube 7 has a thin tube with a diameter of 6.2mm-7mm at the upper end and a thick tube with a diameter of 8mm-9mm at the lower end. It can be used to assemble both detonating cords and detonators. At the same time, the detonator assembly height can be adjusted by adjusting the stepped position, so that the detonator has the function of double detonator detonation or detonating cord detonation, thereby improving the detonation reliability of the detonator.

[0032] The specific assembly method is as follows: the partition plate 3 is assembled in the middle of the shell 1, the mixture of melted retired disassembled and recycled TNT or TNT black explosive, retired propellant grains or retired propellant grains is loaded into the first charging area 4, the retired propellant grains or retired propellant grains are loaded into the second charging area 5, the detonator upper cover 2 is covered, and the product is cooled to obtain the finished product;

[0033] The specific principle is that, by designing a conical energy-gathering hole 9 with an angle of 15 to 150 degrees, a partition plate 3 made of paper, plastic or other materials with a diameter slightly lower than the inner diameter of the outer shell 1 and a thickness of 1mm-3mm, a reasonable blasting height design and a detonator wire pressure groove at the bottom, the detonation wave capability, penetration depth, energy and power of the detonator are improved, while the reliability of detonating insensitive explosives is enhanced. At the same time, retired explosives are used, and through reasonable formula design, the detonator has excellent detonation performance, while retired explosives are processed and disassembled for recycling, thereby reducing waste of resources, reducing pollution to the environment, and saving time and labor costs for processing waste explosives.

[0036] In order to improve the tightness of the connection between the upper cover 2 and the outer shell 1 in this embodiment, first, the threaded plug 11 at the bottom of the upper cover 2 can be threadedly connected to the inner wall of the outer shell 1, so that the upper cover 2 and the outer shell 1 are stably connected, preventing the upper cover 2 from falling off from the top of the outer shell 1. The setting of the sealing ring 12 can improve the sealing performance of the connection between the upper cover 2 and the outer shell 1, preventing the inside of the detonator from being affected by moisture and affecting its use.
