Generally, dynamite such as gelatin dynamite, ammonium nitrate dynamite and the like has been used for industrial explosives in blasting, road construction, mine, building dismantling, fire suppression, towing, tunnel excavation, and other explosion applications.

However, the above-mentioned dynamite is disadvantageous in that the raw material is very expensive and thus the manufacturing cost of the explosive is very high, and when exposed to high temperature, it easily explodes in a natural state, and when it is exposed to moisture, it is hard to be stored and durability is low.

In particular, according to the dynamite manufacturing method disclosed in Korean Patent Publication No. 1992-0014748, the conventional dynamite has a disadvantage in that the manufacturing process is complicated and difficult, and a large number of kinds of materials are used and the manufacturing cost is excessively high.

The above-mentioned dynamite has disadvantages in that it is difficult to manufacture and handle, and frequent safety accidents occur due to the use of a raw material having a high risk of explosion.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view showing explosives using non-explosive solid or liquid according to the first embodiment of the present invention.

1, an explosive 1 using a non-explosive solid or liquid according to a first embodiment of the present invention comprises an explosion container 11 having a housing space formed therein, And an inflation material 12 to be introduced.

The explosion vessel 11 may be configured in various ways without limitation to the shape and structure as long as it has a housing space in which the inflated body 12 can be stored. However, in this embodiment, the container body 111 An insertion port 112 is formed for inputting the inflated material.

The container body 111 is provided with a container stopper 13 which is coupled to seal the insertion opening 112. The container body 111 may be formed of various materials, but in the present embodiment, the container body 111 is formed of an aluminum material having a relatively high thermal conductivity. The container body 111 is preferably formed as thin as possible so that it can explode before the container stopper 13 is detached or destroyed by the inflating force.

The insertion port 112 is formed integrally with the container body 111 and has an insertion hole formed in the insertion port body having an outer diameter smaller than that of the container body and a threaded portion for fastening the container stopper 13 to the container stopper 13 is formed on the outer circumferential surface .

The container stopper 13 is not limited in its shape and structure as long as it can seal the insertion port 112 of the explosion container 11, but in this embodiment, a female screw portion is formed on the inner circumferential surface so as to be fastened to the screw portion formed in the insertion port 112 And is formed in a circular cap shape.

The inflated product 12 can be selected and applied without limitation as long as it is selected and applied from a solid or a liquid which is bulky at the time of heating, and is safe without adversely affecting the human body, animals and plants in a natural state. For example, liquefied nitrogen, liquefied carbon dioxide, or the like can be injected into the expanded material. In this embodiment, however, the expanded volume is relatively large during expansion and is easy to input into the explosive vessel 11, It is characterized by the application of ice (dry ice, which is a solid form of carbon dioxide). At this time, dry ice is applied in the form of pellets. The dry ice pellets can be applied without limitation as long as they have a particle diameter enough to be inserted into the insertion port 112. In this embodiment, the dry ice pellets have a particle diameter of about 1.7 to 3 mm.

2 is a perspective view showing a modified example of an explosive using non-explosive solid or liquid according to the first embodiment of the present invention.

Referring to FIG. 2, the explosive 1 'using a non-explosive solid or liquid has a plurality of dividing grooves 113 formed in the container body 111 in order to enable the explosive monster to be effectively exploded at the time of explosion.

The dividing groove 113 is formed by a plurality of grooves which are recessed in the horizontal, vertical or oblique direction in the container body 111. Since the groove portion is thin and relatively weak in rigidity, When it is applied to the body 111, it is easily cracked and broken. If a plurality of division grooves 113 are formed in the container body 111 as described above, the divided fragments are divided into a plurality of fragments at the time of explosion and scattered, so that the fragments can be more effectively exploded.

The operation of the explosive using non-explosive solid or liquid according to the first embodiment of the present invention as described above will be briefly described.

First, a large number of explosives are prepared simply and safely in such a manner that the container stopper 13 is opened from the explosion container 11, the dry ice (inflator) 12 is injected, and the container stopper 13 is closed again. Such prepared explosives can be used as safe explosives in various industrial fields in place of dangerous dynamite.

For example, in a blast furnace (not shown) of a steel mill, the input iron ore and coke are accumulated in the form of sediments in the blast furnace due to incomplete combustion, and these sediments are formed as walls that block the injection and circulation of oxygen. . At this time, when the explosive prepared as described above is injected through the blast hole of the blast furnace, it penetrates into the deposit layer and is exposed to a high temperature of 1400 ° C or higher. When the explosion container is exposed to a high temperature, the dry ice contained therein is sublimated and rapidly expanded, so that the explosion container explodes with a crack due to the expansion pressure.

When the explosion vessel 11 is exploded, the deposited layer is destroyed and collapsed due to the rapid volume expansion force of the dry ice, so that oxygen injection and circulation inside the blast furnace are smoothly performed, thereby improving the productivity and quality of the iron. Particularly, since dry ice is vaporized by CO ₂ gas in the blast furnace and is annihilated, it does not remain as a foreign substance in the iron ore, so that there is no adverse effect on the quality of iron.

Since the explosive container 21 explodes with the crack due to the expansion pressure of the dry ice, it can be safely used as an explosive that explodes the explosive (decomposed material) at a distance.
