Description

  The present invention relates to a container for loading a bomb or bomb used in a heated blast furnace for safely blasting explosives such as a bomb or a bomb.

Explosives such as ammunition and ammunition that have expired have been discarded in the ocean, deep lakes, or mine shafts. However, such a disposal method is not allowed from the viewpoint of environmental problems. In addition, some of the materials constituting these explosives can be effectively reused as resources, and it is economically disadvantageous to discard them without collecting them.
For this reason, an apparatus has been proposed in which the explosive material is safely blown up and metal scrap is recovered.

In Patent Document 1, a spherical blast furnace is accommodated in an airtight casing heated by a burner, ammunition is accommodated in the blast furnace and heated, the ammunition is blasted and processed, and metal scrap is collected. An ammunition processing apparatus is described.
However, this apparatus has a drawback in that since the structure of the apparatus is complicated, the manufacturing cost is high and only ammunition with a diameter of 60 mm can be processed.

Patent Document 2 proposes an apparatus invention that eliminates the disadvantages of the apparatus described in Patent Document 1. Since the spacer container of the present invention can be applied to such an apparatus, first, this apparatus will be described with reference to the drawings.

FIG. 10A is a cross-sectional view of the heating blast furnace, and FIG. 10B is a cross-sectional view taken along line II in FIG. 10A. FIG. 10C is a cross-sectional view similar to FIG. 10B, but shows a state in which the metal scrap 22 generated by the blasting is taken out.
In FIG. 10, the heat-insulated outer container 1 is suspended on a gantry 2 and can rotate around a horizontal axis 3. The wall of the outer container 1 is provided with a burner 4 for heating the inside of the container and a gas discharge port 5 for discharging combustion gas generated in the burner.

  The outer container 1 is provided with an opening 7 serving both as a shell / bomb loading port for the inner container 6 and a metal scrap discharge port. The opening 7 communicates with the opening 23 of the inner container 6. . The inner container 6 is of a double cone type and has a great resistance to explosion occurring inside, and is supported by the opening 7 portion and the bottom support portion 8 of the outer container 1. The inner container 6 is provided with a discharge pipe 16 for discharging explosive gas.

  In the apparatus configured as described above, the shell and bomb are supplied from the container 21 onto the scrap layer 22 of the inner container 6, and at the same time, the inner container 6 is heated by the burner 4. The explosive material inside the ammunition burns by heating, and the cannonballs and bombs are destroyed, and the metal part forms the scrap layer 22 as scrap. When the processing amount increases and the scrap layer 22 increases, the outer container 1 is rotated by 180 ° C. as shown in FIG. 1 (c), and the metal scrap is discharged from the opening 23 of the inner container 6 into the scrap box 25. . The weir member 24 is provided so that the entire scrap 22 is not discharged.

  Since the heating blast furnace described in Patent Document 2 is a batch type, in order to increase the processing efficiency, a plurality of shells and bombs are accommodated in a container and loaded into a heating blast furnace to generate a plurality of shots. It is necessary to be able to process the shells and bombs at the same time. However, if the cannonballs / bombs come into contact with each other in the container or come into contact with other metal parts at the time of carrying in, a strong impact is generated, and the impact may cause the cannonballs / bombs to explode.

  Regarding the container for transporting artillery and bombs, Patent Document 3 discloses an explosion-proof container that does not harm the human body or surrounding equipment when explosives explode when storing and transporting explosives that may explode. Although this invention is described, it does not provide a means for preventing explosions.

  In the present invention, when a plurality of bombs or bombs (hereinafter referred to as “bombs / bombs”) are processed in a blast furnace, a spacer for loading bombs or the like for preventing the bombs from contacting each other. The purpose is to provide a container.

As a result of intensive studies to solve the above problems, the present inventors have provided a container / bomb holding mechanism on the container so that the shell / bombs do not come into contact with each other, and are provided in the container wall and the container. The present invention has been completed by finding that the above problems can be solved by making holes in the partition wall as much as possible.
That is, the present invention has the following configuration.

(1) A canister or bomb loading spacer container used for simultaneously loading a plurality of bombs or bombs into a batch-type heating and blasting furnace, wherein an atmosphere gas flows through the container wall of the container; A bullet or bomb characterized in that a hole is drilled so that radiant heat directly hits a bullet or bomb, and a spacer is disposed in the container so that the plurality of bullets or bombs do not contact each other. Spacer container for charging.
(2) The canister or bomb loading spacer container of (1) above, wherein the container is made of a combustible material.
( 3 ) The shell or bomb mounting of (1) or (2) above, wherein the opening ratio of the holes in the container wall is 35% or more of the total container wall area, and the opening ratio of each wall including the partition walls is 20% or more. Entering spacer container.
( 4 ) The canister or bomb loading spacer container of the above (1) to ( 3 ), wherein the container is made of cardboard.
( 5 ) The canister or bomb loading spacer container of the above (1) to ( 3 ), wherein the container is made of wood.

The spacer container of the present invention is composed of an outer wall part that forms the outside of the container and a spacer part that holds the plurality of shells / bombs so that they do not contact each other in the container. In this specification, a combination of the outer wall portion and the spacer portion is referred to as a spacer container, and the spacer container wall refers to a wall surface constituting the spacer container.

  The spacer container of the present invention is preferably composed of a combustible material. In the case where the spacer container is made of a combustible material, the spacer container is not combusted, thereby eliminating the heat insulation inhibiting effect. In addition, the heat generated by the combustion of the spacer container can be expected to heat the shells and bombs. However, if the material of the spacer container is a material that generates excessive combustion heat, the upper part of the chamber of the blast furnace is overheated, which is not preferable. Therefore, it is preferable that the material of the spacer container has as little combustion heat as possible. In addition, from the viewpoint of ease of transportation, the material of the spacer container is preferably lightweight.

Specific examples of such combustible materials include, in addition to corrugated cardboard, single board or plywood wood, and plastics such as polypropylene.
Among them, corrugated cardboard can automatically produce containers, and has the advantage that it can be reduced in weight even when it has the same strength as compared with other materials, and there are few variations in products.
Wood can increase the aperture ratio, but it has the disadvantage that it is heavier than cardboard and cannot be produced automatically. In addition, plastic can increase the aperture ratio and has high strength and can be automatically produced, but has the disadvantage that the combustion heat is very large relative to the weight.

To prevent explosion, it is necessary to prevent the shells and bombs from contacting each other, and the simplest spacer container structure to prevent the bombs from contacting each other is the inside of the outer wall without holes. A structure in which a spacer portion (partition plate) without a hole is also conceivable. However, in this case, since the outer wall and the spacer part function as a heat insulating material until the spacer container is burned away, there is a problem that the transmission of radiant heat and conduction heat is excluded and the processing efficiency is lowered.

  In the blasting treatment, it is preferable to shorten the time from when a bomb is placed in one batch to the last explosion as much as possible, for example, 7 to 10 minutes, preferably at most 20 minutes. For this purpose, it is necessary that each of the cannonballs and bombs contained in the spacer container be blown up as simultaneously as possible. However, heat transfer and heat distribution in the blast furnace are not uniform, and at the same time, the blasting cannot be performed and the processing time cannot be shortened.

  For this reason, it is preferable to make a hole in the wall of the spacer container as one embodiment of the present invention. By making a hole in the wall of the spacer container, radiant heat from the furnace wall or scrap bed heated to high temperature (about 550 ° C), conduction heat transfer by contact with the scrap bed, high temperature combustion air in the furnace Heating by conduction heat by passing through and contacting with shells and bombs is performed efficiently. Further, since the end of the box is increased, the box is burned efficiently, and the combustion is finished quickly.

Moreover, it is preferable that the opening ratio is as high as possible within the range that maintains the strength to be lifted in a state where a cannonball is inserted. In particular, it is preferable to increase the opening ratio of the box around the bullet tip so that the bullet tip containing the gunpowder is sufficiently heated. However, on the shell tip axis, do not make a hole in case the shell is displaced.
The opening ratio of the hole should be as large as possible as long as the condition that a person can be lifted in a state where a cannonball is inserted is satisfied, but is preferably 35% or more of the total container wall area, and more preferably 40%. % Or more. Moreover, it is preferable that the opening ratio of each wall including a spacer is 20% or more. The spacers 7 and 8 shown in FIGS. 1, 4 and 7, which will be described later, are shell and bomb support portions, and it is not always necessary to provide openings in these portions.
Below, the example of preparation of a spacer container is shown as an Example. Further, in the embodiments, the description has been given by taking “standard shaped bullets” as an example, but the spacer container of the present invention is used when processing other types of bullets such as “non-shaped bullets” or “red bullets”. It can also be used as a spacer container.
