DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram showing the configuration of an aluminum foil regeneration processing system according to an embodiment of the present invention.
[0010]
In the figure, 1 is a hopper for feeding a sheet material with an aluminum foil, 2 is a shredder (crusher) for crushing the fed sheet material into small pieces, and 3 is an aluminum material by heating the crushed sheet piece at a predetermined temperature. In a vacuum furnace (heating means) for burning paper materials other than the above, it is burned in a reduced pressure state by a vacuum pump at a temperature of about 500 ° C to 600 ° C.
[0011]
Reference numeral 4 denotes a secondary combustion furnace provided in the vacuum furnace 3, which is connected to an exhaust gas cooling device, a cyclone, a bag filter, and an exhaust fan, not shown.
[0012]
5 is a granulator for forming a sheet piece heated by the vacuum furnace 3 into particles, and 6 is a vibrating screen (separating means) for removing carbon generated by the above-mentioned combustion from the granulated material. Aluminum material and carbon are accommodated in the respective containers 7 and 8. Although not shown, a small dust collector is connected to the vibrating screen 6.
[0013]
The heating temperature in the vacuum furnace 3 is preferably controlled to around 600 ° C.
[0014]
FIG. 2 is a flowchart showing the operation of the reproduction processing system configured as described above. The sheet material put in from the hopper 1 is first transported to the shredder 2 by a conveyor, where it is crushed into small pieces (step S1).
[0015]
The small crushed sheet pieces are fed into the vacuum furnace 3, and at this time, they are fed by a certain amount by a weight sensor (not shown). And it heats with this vacuum furnace 3 (step S2), and a paper material is combusted.
[0016]
The sheet piece (aluminum material) from which the paper material has been removed in the vacuum furnace 3 is guided from the conveyor to the granulator 5 and formed into granular pellets (step S3). Then, the aluminum pellet and the carbon are separated by the vibrating screen 6 (step S4), and the aluminum pellet is collected in a predetermined container 7.
[0017]
In this way, the aluminum material is recovered from the sheet material. In this embodiment, the vacuum furnace 3 is used to separate the paper material and the aluminum material, and the aluminum material is heated at a temperature of about 600 ° C. The material can be recovered with high purity without being oxidized. Further, a simple and inexpensive configuration is possible.
[0018]
FIG. 3 is a block diagram showing the configuration of another embodiment of the present invention. The same reference numerals as those in FIG. 1 indicate the same components. In the figure, reference numeral 21 denotes a press-feeding device for pressing and feeding a sheet material with an aluminum foil to an appropriate size.
[0019]
In this embodiment, a plurality of sheet materials are press-molded and charged, and the press-molded product is heat-treated in the vacuum furnace 3. Then, after the heated press-molded product is crushed into small pieces by the shredder 2, it is formed into granules by the granulator 5. Similarly to the above-described embodiment, the carbon is removed by the vibrating screen 6 and high-purity aluminum is recovered.
[0020]
Even with such a configuration, the same effect as the above-described embodiment can be obtained, and valuable metal resources are not wasted.
[0021]
In addition, it is effective in terms of transportation and storage to compress the recovered aluminum material with a press to form a solid material, and can be used in a wide range of applications.
[0022]
【The invention's effect】
As described above, according to the present invention, an aluminum material can be recovered with high purity from a sheet with an aluminum foil with a simple and inexpensive configuration, and there is an effect that valuable metal resources are not wasted. .
