When the object to be sorted 20 is introduced into the zigzag pipe 11 from the insertion port 11a, the object to be sorted 20 is loosened by turbulence generated by the shape effect of the zigzag pipe 11, and among these, the light object 21 is a suction blower. 12 rises under the influence of the updraft by 12 and is recovered by being centrifuged from the stream by the cyclone 13. On the other hand, the heavy object 22 is collected from the lower side of the zigzag pipe 11 because the influence of gravity is stronger than the ascending airflow generated by the suction blower 12.

  The wet jig specific gravity separator 30 schematically shown in FIG. 5A includes a water tank 31, a pulsating water flow generator (not shown), a weir 32, and a take-out port provided at a predetermined height position of the weir 32. 33. When the separation object that sinks in water is put into the water tank 31, as shown in FIG. 5B, the low specific gravity 41 and the high specific gravity 42 are separated and stratified by the pulsating water flow, and the low specific gravity 41 is caused by the pulsating water flow. Overflowing from the upper end of the weir 32 is recovered, and the high specific gravity 42 is recovered from the outlet 33. The low specific gravity is recovered by overflowing from the upper end of the weir 32 by the pulsating water flow, the medium specific gravity is recovered from the take-out port 33, and the high specific gravity remains in the water tank. It is also possible to select and separate specific gravity and high specific gravity.

  In the flow sheet shown in FIG. 1, waste (for example, bicycles, stoves, video tapes, carpets, baskets, etc.) discharged from ordinary households and collected as non-burnable or oversized waste by the local government is crushed by a crusher.

  Next, the magnetic material such as iron is adsorbed and recovered from the crushed material crushed by the crusher using a magnetic separator.

  Next, the crushed material from which the magnetic material has been collected is separated and separated by a Trommel type sieving machine having a sieve diameter of 30 mm.

  Then, the crushed material under φ30 mm under the sieve is sorted and separated into light and heavy by a zigzag wind power sorter. Here, combustible materials mainly composed of plastics, wood / paper / cloth, rubber, and urethane are separated and recovered as lightweight materials.

  Next, what is separated as a heavy object by the zigzag type wind power sorter is separated into a low specific gravity object and a high specific gravity object by a wet jig specific gravity separation device. Here, combustible materials such as solid plastics and rubber are mainly separated and recovered as the low specific gravity material, and incombustible materials such as iron and non-ferrous metal are separated and recovered as the high specific gravity material. If necessary, iron and non-ferrous metals are separated and recovered from non-combustible materials such as iron and non-ferrous metals separated and recovered.

  On the other hand, non-ferrous metals such as aluminum are mainly separated and recovered from the crushed material on the sieve of the trommel type sieve by an aluminum sorter.

  Next, the crushed material from which the non-ferrous metal has been separated and recovered is separated into light and heavy items by a zigzag wind power sorter. Here, combustible materials mainly composed of plastics, wood / paper / cloth, rubber, and urethane are separated and recovered as lightweight materials.

  Next, what is separated and recovered as a heavy material by the zigzag wind power sorter is separated into a low specific gravity material and a high specific gravity material by a wet jig specific gravity separation device. Here, combustible materials such as solid plastics and rubber are mainly separated and recovered as the low specific gravity material, and incombustible materials such as iron and non-ferrous metal are separated and recovered as the high specific gravity material. If necessary, iron and non-ferrous metals are separated and collected from non-combustible materials such as iron and non-ferrous metals that have been separated and collected.

  As described above, in this embodiment, in the case of garbage collected as incombustible waste or bulky waste, conventionally combustible material contained in the waste is sorted and separated into incombustible material and disposed of in landfill. As a result, the amount of landfill disposal can be reduced. In addition, since the incombustible material contained in the incinerator is separated and recovered from what is conventionally separated and combusted by combustible material, the molten aluminum in the incinerator is supplied to each part in the furnace. The problem of adhesion and accumulation and the problem of foreign matter contamination in the ash melting furnace following the incinerator are avoided, enabling thermal recycling as a high-quality combustible material, and separation and recovery of valuable materials such as iron and iron metal. Become.

  That is, with respect to the garbage collected as incombustible waste or oversized waste, the incombustible material and the combustible material can be sorted and separated accurately and efficiently, and the effective use of the waste can be improved.

(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a flow sheet showing a processing procedure in this embodiment.

  The processing procedure in this embodiment shown in FIG. 2 is substantially the same as the processing procedure in the first embodiment shown in FIG. 1, except for the following points.

  That is, in the first embodiment, the crushed material under φ30 mm below the sieve that has been sorted and separated by the Trommel type sieve having a sieve diameter of φ30 mm is separated into light and heavy by a zigzag wind sorter. On the other hand, in this embodiment, the crushed material under φ30 mm under the sieve that has been sorted and separated by the Trommel type sieve having a sieve diameter of 30 mm is classified in advance by a sieve having a sieve size of 10 mm or less, and the top of the sieve is zigzag type wind power sorting. The machine sorts and separates light and heavy items. Here, the sieves classified by a sieve having a sieve size of 10 mm or less are mainly crushed glass and sand. By separating and removing these in advance, a subsequent zigzag wind power sorter and wet jig specific gravity separation are used. Sorting and separation in the apparatus can be performed more accurately and efficiently.

(Third embodiment)
A third embodiment of the present invention will be described with reference to FIGS. FIG. 3 is a flow sheet showing the processing procedure in this embodiment. FIG. 6 is an explanatory diagram of a swinging sorter used in this embodiment.

  The processing procedure in this embodiment shown in FIG. 3 is substantially the same as the processing procedure in the first embodiment shown in FIG. 1 except for the following points.

  That is, in the first embodiment, instead of sorting and separating the crushed material from which the magnetic material has been collected by a trommel type sieving machine, in this embodiment, the crushed material from which the magnetic material has been collected is swung. Sorted and separated by a type sorter.

  As shown in the perspective view of FIG. 6A and the side view of FIG. 6B, the oscillating sorter 50 includes a plurality of inclined screens 52 provided to be inclined inside the chamber 51, There are provided eccentric drive mechanisms 53 arranged at four positions on the left and right sides of the inclined screen 52, and sieve holes 52c provided on the surface of the inclined screen 52, and the inclined screen 52 is inclined upward by driving the eccentric drive mechanism 53. Thus, a swinging motion is performed so as to reciprocate in the vertical direction and the tilt direction. Then, when the sorting object 60 is put on the inclined screen 52, the mass 61 has a large repulsive force, so that it bounces downward in accordance with the inclination of the inclined screen 52, and as a result is discharged from the inclined lower side 52a. On the other hand, since the repulsive force of the sheet-like material 62 is small, the sheet-like material 62 is not lifted up on the inclined screen 52, and is conveyed upwardly by the swinging motion, and as a result, is discharged from the inclined upper side 52b. An object smaller than the diameter of the sieve hole 52 c on the surface of the inclined screen 52 is discharged as a small particle size 63 below the inclined screen 52.

  And in this embodiment, the same processing procedure as the sieving of the Trommel type sieving machine in the first embodiment is applied to the sieving (small particle size product) sorted and separated by the swing type sorting machine, By applying the same processing procedure as that for the trommel sieving machine in the first embodiment to the lump separated by the oscillating sorter, the sheet separated by the oscillating sorter is combustible. It is collected as a thing.

  As described above, in this embodiment as well, in the same manner as in the first embodiment, it is possible to sort and separate the non-combustible material and the combustible material with high accuracy from the garbage collected as non-combustible waste or bulky waste. It is possible to improve the effective use of garbage.

  An example in which sorting and separation of garbage collected as incombustible waste or bulky waste according to the above-described second embodiment of the present invention is shown below.

  Garbage collected as non-combustible waste or bulky waste was crushed, and magnetic materials such as irons were separated and collected by a magnetic separator, and then separated by a Trommel type sieve having a mesh size of 30 mm.

  And under the sieve, classification was further performed with a sieve having a sieve mesh of 2.36 mm, and the top of the sieve was sorted and separated into a light and heavy article by a zigzag wind sorter. As lightweight materials, fluffy plastics such as videotapes, wood, paper and cloth were separated and collected. Furthermore, the heavy objects in the zigzag type wind power sorter were separated and separated into three layers of low specific gravity, medium specific gravity, and high specific gravity using a wet jig specific gravity separator. Solid plastic and wood / paper / cloth were separated and recovered as low specific gravity, and glass was separated as medium specific gravity. Moreover, about the high specific gravity thing, valuables were collect | recovered by isolate | separating and collect | recovering iron with a magnetic separator and separating and recovering nonferrous with an aluminum sorter. Table 1 shows the separation and recovery ratios described above.

  Conventionally, all the sieving of the trommel sieving machine has been disposed of in landfill, but in this embodiment, the sieving of the trommel sieving machine is 5% as a lightweight material in the zigzag wind power sorter, and the wet jig specific gravity A total of 40% of 35% as low specific gravity in the separation device could be recovered as combustible material. As a result, thermal recycling became possible and a drastic reduction in landfill disposal was achieved.

  On the other hand, for the crushed material separated on the sieve of the Trommel type sieving machine, the non-ferrous metal sorter (aluminum sorter) separates and collects mainly non-ferrous metals such as aluminum and copper, and then the zigzag wind sorter reduces the weight. And separated into heavy items. As lightweight materials, fluffy plastics such as videotapes, wood, paper, cloth, and rubber were separated and collected. Further, the heavy objects in the zigzag type wind power sorter were separated and separated into two layers of a low specific gravity substance and a high specific gravity substance by a wet jig specific gravity separator. Table 2 shows the separation and recovery ratios described above.

  Conventionally, all of the sieves of the trommel type sieving machines have been incinerated, but in this example, 55% of incombustibles are used as high specific gravity substances in the wet jig specific gravity separator on the sieves of the trommel type sieving machines. It was possible to separate and recover. In addition, about the high specific gravity thing in a wet jig specific gravity separation apparatus, iron was isolate | separated and collect | recovered with the magnetic separator, and valuables were collect | recovered by isolate | separating and collect | recovering nonferrous metals with the aluminum separator. This avoids the problem of adhesion and deposition of molten aluminum to each part of the furnace in the incinerator and the problem of foreign matter contamination in the ash melting furnace following the incinerator, and enables thermal recycling as a good combustible material. At the same time, it became possible to separate and recover valuable materials such as iron and iron metal.
