Next, the waste treatment apparatus 1 having the above structure
The operation of 0 will be described. First, the waste treatment device 10
Is operated to load the garbage bag B containing the waste from the charging port 12 of the small crusher 14. The small crusher 14 crushes the waste together with the garbage bag B and discharges it as a crushed product H into the pipeline 18. Each small crusher 14 crushes and discharges the waste. The waste can be thrown into a plurality of small crushers 14 at the same time to carry out a crushing process, and it is also possible to throw the waste continuously into one small crusher 14. Therefore, the waste can be taken out from the entrance / exit 16 of the vehicle T or the garbage outlet and put into any small crusher 14 installed in the vicinity thereof, so that the garbage bag B containing the waste can be manually or turreted. No need to transport.

The crushed material H crushed by the small crusher 14 and discharged is pressure-fed in the pipeline 18 and discharged into the first air chamber 24. Since the inside of the first air chamber 24 is sucked by the power unit 30 via the light material pipe 26 and the second air chamber 28, the crushed material H that has been pressure-fed through the pipeline 18 and has entered the first air chamber 24 is a relative member. Will be depressurized first
The particles are dispersed and float inside the body 24a of the air chamber 24. In addition, in the first air chamber 24, the inlet nozzle 24
Since air flows from b to the body 24a to the outlet nozzle 24c, the light material of the crushed material H dispersed / floating in the body 24a is discharged from the outlet nozzle 24c according to the above-described air flow, and the light material is discharged. It is transferred to the second air chamber 28 via the pipe 26. On the other hand, the heavy substances of the crushed material H gradually settle and are deposited on the upper side of the damper 24d installed at the lower portion of the case 24a. The heavy material deposited on the upper side of the damper 24d is the damper 24d at an appropriate timing,
It is discharged to the crusher 32 by the opening / closing operation of 24e.

It floats inside g and is discharged from the discharge pipe 42d together with air. In addition, heavy materials are accumulated in the lower part of the rotary drum 42g and fall from the drop port 42h to the screw conveyor 42b.

The light material discharged from the discharge pipe 42d is discharged to the light material pipe 26 through the outlet nozzle 36c and transferred to the second air chamber 28. On the other hand, the heavy objects dropped from the drop port 42h are
It is conveyed by 2b and discharged from the lower part 36b. The conveyance by the screw conveyor 42b also exerts an effect of decomposing the above-mentioned agglomerates that have not been sufficiently agglomerated, so that the agglomerates that have not been agglomerated are prevented from being discharged from the lower portion 36b.

The heavy substances discharged from the lower portion 36b of the third air chamber 36 are transferred to the fourth air chamber 44 and dispersed / floated in the same manner as in the first air chamber 24 described above. As a result, the light material mixed in the heavy material is separated and discharged from the outlet nozzle 44b to the light material pipe 26. On the other hand, the heavy material settles and accumulates on the bottom of the fourth air chamber 44, and is discharged from the lower portion 44c at an appropriate timing.

The heavy substances discharged from the lower portion 44c of the fourth air chamber 44 are put into the electromagnetic sorter 48. In the electromagnetic sorter 48, first, the permanent magnet 48c and the rotary cylinder 48 are
The magnetic metal F is separated by the action of b and accumulated in the magnetic metal recovery box 48e. In the case of waste generated in the train, the magnetic metal F is iron or steel derived from a beverage can or the like, and thus can be recovered and effectively reused.

The heavy material separated from the magnetic metal F falls on the endless belt 48j and is transferred by the endless belt 48j. When a heavy object reaches the rotation shaft 48h, the electromagnet 48
By the action of the eddy current generated by the alternating magnetic field due to k, the non-magnetic metal AL such as aluminum contained in the heavy material is blown off from the endless belt 48j, the falling course is regulated by the partition plate 48m, and the non-magnetic metal recovery box 48n is provided. Fall,
Accumulated. In the case of waste generated in trains, most non-magnetic metal AL is aluminum derived from beverage cans and the like, so it can be recovered and reused effectively. Also, the endless belt 4
The non-metal G that has been transferred by 8j and reached the folded portion of the endless belt 48j is separated from the endless belt 48j and falls. At this time, the partition plate 48m prevents the non-magnetic metal AL and the non-metal G from mixing during the fall.

As described above, in the electromagnetic separator 48, the magnetic metal F, which is mainly iron or steel, the non-magnetic metal AL, which is mainly aluminum, and the non-metal G, are efficiently and accurately separated and accumulated. Therefore, it is easy to recycle iron and steel (magnetic metal F) and aluminum (non-magnetic metal AL).

On the other hand, the air is discharged from the first air chamber 24, the third air chamber 36 and the fourth air chamber 44,
The light substances transferred to the second air chamber 28 via the light substance pipe 26 gradually settle inside the second air chamber 28 and are deposited on the bottom. The accumulated light material is discharged from the lower portion 28c at an appropriate timing and is carried out to an incineration facility or the like by a truck, for example.

As shown in, in the lower portion 28c of the second air chamber 28,
The packing unit 62 is connected and used. As described above, the light substances accumulated in the second air chamber 28 are discharged from the lower portion 28c into the packing unit 62, the connection nozzle 70 is opened, and the suction unit 66 is operated. Then, the inside of the packing unit 62 is decompressed,
The light material accumulated in the packing unit 62 is compressed,
Volume is reduced. Further, after the set amount of light material is accumulated and reduced in the packing unit 62, the lever 72 is operated to close the connection nozzle 70 and stop the roots pump 64. After this, the flexible hose 68 is connected to the connecting nozzle 70.
The packing unit 62 and the suction unit 66 are separated from each other.

The separated packing unit 62 is loaded into a truck or the like while containing the light items, and is transported to, for example, an incineration facility. In the incineration facility, the light material is taken out from the packing unit 62 and incinerated. The empty packing unit 62 is collected and repeatedly used.

Also, another packing unit 62 can be connected to the suction unit 66 separated from the packing unit 62 to perform the same work as described above. As described above, in the waste treatment device 10 of the present embodiment, the small crushers 14 installed under the platform of the station and between the lines are used to collect the dust taken out from the entry / exit 16 of the vehicle T and the trash exit. The bag B is crushed, sorted, and discharged by simply loading the bag B. Therefore, the manual work only needs to collect waste in the vehicle and load the compact crusher 14. Therefore, a large amount of waste can be quickly processed.

Further, since it is not necessary to collect the dust bags B, it is not necessary to carry out the work in an environment that is not necessarily good such as transportation on the track or transportation under the platform. Moreover, the metals in the waste can be effectively recovered, which is effective in recycling resources.

Further, since the apparent volume of the light material can be reduced by using the volume reduction packing machine 60, the work can be efficiently performed in the subsequent processing, for example, when the light material is carried out to an incineration facility or the like.
