[0001] PALLET TYPE CASE FOR PROPELLANT CHARGE USING PCM [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet type propellant charge container using a PCM, and more particularly, to a propellant charge container capable of maintaining a constant internal temperature by inserting a PCM BEAM inside a container.

In general, propellant charge is a gunpowder which pushes the warhead forward in the gun, and it consists of several unit charges so that it can fire by adjusting the gun number according to the range.

The charge in the barrel is ignited by the primer and propels the shell forward by the explosive force. These charges are housed in a metal bag and stored in most ammunition cartridges. Some of them are loaded from combat equipment, such as self-propelled booms, and are promptly opened and loaded into barrel in case of emergency.

In other words, the propulsion charge is packed in steel tantalum and then palletized (steel banding) usually in 20 ~ 30 foot units, and the military takes over most of the propulsion charge in the ammunition warehouse, And then, after opening the lid of the long pail, in case of emergency, the propulsion charge is taken out and shot.

However, according to the above-described related art, since the long and short barrels are manufactured individually and the pallet is packaged, it is required to bend the reinforcing neck with the iron strip, which requires a lot of time, effort, and cost.

In addition, since the intestinal pouch is made of a material having high thermal conductivity, it easily assimilates to an external temperature, shortens the service life of the medicine, and is easily corroded.

In addition, the corrugated cardboard is sandwiched between the propellant charge and the inner wall to exhibit the effect of heat insulation and hygroscopicity inside the intestinal canal. However, since it has a low persistence and acts as a warming effect, the natural decomposition reaction accelerates, shortening the life span and spontaneous ignition have.

Also, conventionally, in order to prevent the moisture from being introduced into the intestinal canal, it is packed at a level of 3 to 4 psi and packed. However, there is a problem that the airtightness is weak and the pressure easily leaks and moisture is introduced.

In addition, since each propellant charge is individually sealed in a steel tin tube, it is impossible to identify the charge state from the outside, so two or three samples are taken at random from each lot and then subjected to physicochemical tests to maintain or dispose of the propellant charge It is judged whether or not to dispose of only a few samples out of the thousands or tens of thousands of feet per lot, and the usable charges are also discarded at the same time, resulting in waste of budget.

In order to prevent such a mistake, it is necessary to increase the number of samples and to increase the number of physicochemical inspection personnel in order to judge whether or not the waste is more accurately discarded. In the reality that the personnel reduction of the military is inevitable, It will be appropriate to pursue improvement in the future.

Preferably, the intestinal can (400) is in the form of a cylinder in which a medicine can be stored, and is preferably made of a conductive material such as metal.

A support portion 600 for supporting the insertion tube 400 is installed in the case 200 so that the insertion tube 400 can be maintained vertically standing on the space portion 210. As an example, the support portion 600 may be formed as a support bracket (not shown) having a predetermined width and a predetermined length. In this case, it is preferable that a pair of support brackets are provided at the upper and lower ends of the space portion 210 so as to be spaced apart from each other. The outer rim of the support bracket is tightly supported on the inner wall of the case 200, The intestine can be inserted into the groove and the outer circumferential surface of the intestine 400 can be supported by the support bracket.

According to the present embodiment, the support portion 600 is formed of a pair of plates 610 and 620, the rims being supported on the inner wall of the case 200 and spaced apart from each other in the vertical direction of the space portion 210. The mounting holes 630 of the upper plate 610 and the mounting holes 630 of the lower plate 620 are formed to be opposed to each other through the plurality of mounting holes 630 in the plates 610 and 620, .

As another example, coupling protrusions (not shown) may be formed on the upper plate 610 and the lower plate 620, and coupling grooves (not shown) may be formed on the inner wall of the case 200 to couple them. Of course, it is also possible to form coupling grooves in the upper plate 610 and the lower plate 620, and to form coupling protrusions on the inner wall of the case 200.

FIG. 3 is a schematic view showing the arrangement of a latent heat unit according to an embodiment of the present invention, and FIG. 4 is a plan view of a pallet-type propellant charge vessel using a PCM according to an embodiment of the present invention.

As shown in FIGS. 3 and 4, at least one latent heat unit 500 is accommodated in a space between the upper plate 610 and the lower plate 620. The latent heat unit 500 includes a beam-shaped pouch containing a latent heat material containing a phase change material (PCM). The pouch is made of a thin metal thin film material such as synthetic resin or aluminum, . As another example, the latent heat unit 500 is in the form of a thin sheet having a rectangular shape, and includes a resin layer having a honeycomb structure, a phase change material in the form of a capsule filled between the resin layers, And a cover layer attached to the resin layer. In this case, the phase change material itself may be in the form of a capsule, while a separate microcapsule may be prepared and filled with a phase change material inside the capsule. The user can cut the sheet filled with the phase change material to a desired size and roll it into the space 210 of the case 200 in the form of a beam to easily use the sheet. The latent heat unit 500 inserted into the space 210 serves to fix the intestinal canal 400 and to protect the intestinal canal 400 from external impacts.

PCM (phase change material) is a substance that absorbs or releases latent heat by changing the phase of a solid and a liquid at a certain temperature, and usually has a low melting point (melting point) and has a high heat storage capacity. Since PCM stores various types of energy (unutilized and waste energy) at a high concentration, it can be suitably converted to the use field, timing and purpose, so that the energy can be utilized efficiently and reasonably. In addition, since the latent heat and heat storage performance are excellent, even when heat is penetrated from the outside, the phase of the material changes, and the temperature can be kept constant by absorbing the penetrated heat.

If necessary, a dehumidifying agent such as charcoal, zeolite, or silica gel may be contained in a separate space separated from the latent heat material. Preferably, the dehumidifying agent is placed in a pocket of a breathable paper or cloth material and disposed on one side of the space 210 do.

The latent heat unit 500 is accommodated in a space between adjoining intestinal canisters 400 so that one side is supported on one side of the outer circumferential surface of the intestinal can body 400 and the length of the latent heat unit 500 accommodated in the case 200 The specification, the number and the installation position can be appropriately selected as needed. Heat and moisture generated in the upper and lower plates 610 and 620 are transferred to the latent heat unit 500 through the upper plate 610 and the lower plate 620, A communicating hole 640 for air circulation is formed so as to be opposed to the latent heat unit 500 so that the latent heat material and the dehumidifying agent of the latent heat source and the dehumidifying agent can be absorbed. That is, as shown in FIG. 4, a communication hole 640 is formed through the plurality of mounting holes 630 through which the insertion slot 400 is inserted.

According to an embodiment of the present invention, as described above, the latent heat unit 500 is disposed between the long containers 400, so that the inside of the case 200 can be maintained at a predetermined temperature and humidity (for example, , A temperature of about 15 ° C / year, and a relative humidity of 50% or less), thereby guaranteeing the life and performance of the propellant charge.

Referring again to FIG. 2, the cover 300 is coupled to cover the opening of the case 200. A vacuum nozzle 220 communicating with the space 210 is provided on one side of the case 200 such as the bottom of the case 200. After the insertion of the long container 400 and the coupling of the cover 300, A vacuum pipe (not shown) is connected to the nozzle 220 and a vacuum pump (not shown) is operated to form the inside of the propellant charge container 100 in a vacuum atmosphere. After forming the vacuum atmosphere, it is preferable to close the vacuum nozzle 220 with a component such as a cap. According to the embodiment of the present invention, the humidification of the propellant charge vessel 100 is removed in the vacuum atmosphere forming process, and the natural decomposition reaction of the charge is minimized.

At this time, a vacuum valve 700 made of a thin insulating material such as glass fiber is interposed between the case 200 and the cover 300 so that a vacuum atmosphere by the vacuum nozzle 220 can be maintained. The vacuum valve 700 may be attached to the upper end of the case 200 by thermal fusion or the like and may have a shallow broken groove (not shown) in a dotted line along the rim for easy opening in the field, It is preferable to be able to be easily cut and separated by applying a certain pressure or impact.

The vacuum valve 700 is provided at one side thereof with a temperature and humidity indicator 710 (see FIG. 5) for measuring the temperature and humidity of the space 210 in which the container 400 is mounted. An observation window 310 made of a transparent material is formed so that the numerical value of the temperature and humidity indicator 710 can be visually confirmed. That is, according to one embodiment of the present invention, the numerical values of the temperature and humidity indicator 710 provided on the vacuum valve 700 through the observation window 310 of the cover 300 are visually observed, Temperature and humidity. Of course, as another example of the present invention, a thermometer and / or a hygrometer may be provided in place of the temperature and humidity indicator 710.

A cushioning material 800 made of an elastic material such as rubber or silicone may be attached to the bottom surface of the case 200 and the bottom surface of the case 200 in order to absorb shock transmitted to the long- (Not shown). The cushioning material 800 is provided so as to face both ends in the lengthwise direction of each of the insertion containers 400.

In general, the design life of a propellant charge is 30 years. Traditionally, thousands of individual long packs (400) were bundled in pallet packages and random samples of each lot were inspected for maintenance or disposal. In some cases, thousands of propulsion charges were simultaneously discarded, resulting in a waste of funds. In addition, since the intestinal canal has been closed in the past, there is no way to check the internal temperature and humidity, so the physicochemical test was conducted every 10 years.

On the other hand, in the case of the pallet type propellant charge vessel 100 using the PCM according to the embodiment of the present invention, since the internal temperature and humidity state can be confirmed, the physicochemical test can be carried out for 25 years or 30 years of the design life Do. As a result, the number of physicochemical tests for single-lot ammunition is greatly reduced, allowing for more samples (now sampling from 2 to 3 samples per lot) and more chemistry tests for more lot ammunition, It is possible to judge categorization of ammunition by lot and contribute to budget reduction.

In addition, since the long barrel and the pallet banding material are made of iron in the past, corrosion is progressed in the igloo ammunition especially in the summer when moisture and condensation are severe, and the banding is broken or the long barrel is rusted, Moisture may be introduced. If it gets worse, the propellant charge should be disposed of. Therefore, before the explosion is checked, the intestinal canal and the bending state are inspected. If the corrosion is serious, the intestinal canal is replaced or repainted and rebounded.

At this time, the condition of the propellant stabilizer is also inspected together and repackaged if there is no abnormality. According to the embodiment of the present invention, the maintenance procedure is also significantly simplified as follows.

First, the cover 300 is opened and the vacuum valve 700 is removed. The propellant charge is drawn out from the intestinal canal 400 to perform the physicochemical test. If there is no abnormality, the intestinal canal is repacked and inserted into the intestinal canal 400 again. If necessary, the dehumidifying agent is replaced, the vacuum valve 700 is attached, and then the cover 300 is coupled. After the cover 300 is coupled, a vacuum pump is connected to the vacuum nozzle 220 to decompress and seal the inside of the cover 300 and store the same in a storage place.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
