Technical Field

[0001] The utility model mainly relates to the field of explosive packaging, in particular to an industrial explosive composite packaging tube used in special working environments. Background Art

[0002] Emulsion explosives are commonly used explosives in mining, tunneling, underwater operations and other projects. When conducting mountain opening or tunnel directional blasting, in order to ensure sufficient explosive power, it is usually necessary to connect multiple emulsion explosives for simultaneous blasting. At present, construction workers usually use a bundling method to tie the emulsion explosives to the same bamboo pole and insert them into the drilled holes for use. This method requires complex operations on site, which not only ensures the stability of the bundle, but also controls the distance between the emulsion explosives. At the same time, it is also necessary to pay attention to the state of the inserted detonator to prevent the detonator from loosening and falling. In short, the current method of using emulsion explosives has a complicated operation process and poor connection status. Utility Model Content

DETAILED DESCRIPTION

[0024] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0025] like Figure 1-6 As shown, the utility model discloses an industrial explosive composite packaging cylinder for special working environments, comprising a shell 1 and a cap 2, wherein the shell 1 is made by blow molding and the cap 2 is made by injection molding. The shell 1 is a circular vertical cylinder, and the top of the shell 1 has an opening 11, which serves as an inlet for the emulsion explosive. The shell 1 serves as a secondary packaging shell for the emulsion explosive, and the emulsion explosive is re-placed into the shell 1 after being packaged with a plastic film. The cap 2 serves as a closing component of the opening 11, and can complete the closed packaging of the emulsion explosive.

[0026] The top of the shell 1 has an internal threaded portion 12, which is expanded, and the diameter of the internal threaded portion 12 is larger than the bottom diameter of the shell 1. The bottom of the shell 1 is provided with an external threaded portion 14. The internal threaded portion 12 at the top of one packaging shell is matched with the external threaded portion 14 at the bottom of another packaging shell for connection, so that multiple emulsion explosives can be stably connected for use. The threaded connection makes the whole after connection more stable, ensuring better use effect.

[0027] An engaging groove 13 is provided below the internal threaded portion 12. The engaging groove 13 is an annular groove extending from the inside to the outside. In this embodiment, two engaging grooves 13 are provided in an upper and lower position relationship. The bottom of the cap body 2 has an insertion end 21. The bottom of the insertion end 21 is a pointed end, so that it is easy to insert into the emulsion explosive. The insertion end 21 is a hollow structure. The top of the insertion end 21 has a receiving channel 23 that passes through the cap body 2. The receiving channel 23 serves as the placement position of the detonator. The bottom of the insertion end 21 is closed to prevent the detonator from falling excessively.

[0028] A clamping block 22 is provided on the outer edge of the cap body 2, and the clamping block 22 cooperates with the fitting groove 13. When the cap body 2 is installed, the insertion end 21 is inserted into the emulsion explosive of the shell 1, and the clamping block 22 squeezes the top of the shell 1, and then is clamped into the fitting groove 13 for fixing, so as to seal the emulsion explosive. A wire hole 15 is provided on the outer wall between the internal thread part 12 and the fitting groove 13, and the detonating wire of the detonator passes through the wire hole 15 and is connected to the detonator.

[0029] More specifically, the clamping block 22 is an arc-shaped structure, and two clamping blocks 22 are symmetrically arranged on both sides of the cap body 2. When the cap body 2 is installed, the cap body 2 and the shell 1 are deformed by extrusion, so that the clamping block 22 of the cap body 2 is squeezed into the fitting groove 13, so that the cap body 2 can be stably fixed in the shell 1.

[0030] The emulsion explosive can be pre-loaded into the shell 1, or the two can be shipped separately and assembled by on-site construction personnel. When the emulsion explosive is connected for use, the cap body 2 is inserted into the emulsion explosive, and the cap body 2 and the fitting groove 13 on the shell 1 are clamped, and then the detonator is placed in the channel of the insertion end 21, and the detonator connection line is passed through the wire hole 15. Then, multiple shells 1 are connected by hanging and tightening the internal thread part 12 and the external thread part 14, and the connection is more stable and convenient, and there is no need to worry about the detonator falling off, which can ensure a more stable use effect.

[0031] The internal thread of the internal thread part 12 is in a discontinuous state, and a plurality of notches 16 for interrupting the internal thread are arranged in an array on the internal thread part 12. The notches 16 can keep the gas discharged smoothly during the threaded connection, making the connection more stable.

[0032] More specifically, a ring 17 is provided at the top of the internal threaded portion 12, and a boss 18 is provided at the top of the external threaded portion 14. After the internal threaded portion 12 and the external threaded portion 14 of another shell 1 are tightened, the ring 17 and the boss 18 cooperate to complete the positioning and sealing of the connection between the two shells 1.

[0033] The top of the cap body 2 is flat and can be used in conjunction with a manipulator. The cap body 2 can be automatically pre-loaded by grabbing it with a vacuum suction cup before leaving the factory, thereby further improving efficiency, reducing the degree of human involvement, and ensuring safe production in explosives production plants.
