Solid waste in which various solids such as metals, glasses, and plastics are mixed is put into the hopper 21 of the crusher 20, crushed at the crushing section 22, and discharged from the discharge port to the take-out conveyor 2 below. To do.
The crushed solid waste is transferred from the take-out conveyor 2 to the carry-in conveyor 3 and sent to the first wind power sorter 30, and falls from the charging port 34 onto the mounting plate 35. Here, heavy objects such as metals and glasses that are not affected by the wind force fall on the flat portion 35a of the mounting plate 35 and gradually move to the first blower opening 36 side due to the vibration of the mounting plate 35. Then, it is discharged from the heavy material discharge port 39 to the first sorting conveyor 4. On the other hand, lightweight materials such as plastics are floated by being blown from the bottom of the mounting plate 35 by being blown from the second blower pipe 371 and being blown off in the lateral direction by being blown from the first blower pipe 361.

And the solid waste other than iron is sent to the second wind sorter 40 by the first sorting conveyor 4. In this second wind power sorter 40, the first wind power sorter 30
In the same manner as the above, the first wind sorter 30 does not sort the light weight objects that have been entangled with the heavy objects and are discharged together with the heavy objects by the wind blown from the bottom of the mounting plate, and the horizontal direction. Then, it is blown off to the second light weight conveyer conveyor 11 from the discharge part 41, while the heavy weight is discharged to the second sorting conveyor 6.

The solid waste sorted by the second wind sorter 40 as a heavy load and discharged onto the second sorting conveyor 6 is sent to the final sorting conveyor 7, where non-ferrous metals are sorted by hand while being transported. The remaining solid waste is conveyed by the final sorting conveyor 7 and stored in the residue storage unit 9 while being stored in the non-ferrous metal storage unit 8.

On the other hand, the solid waste sorted by the first wind power sorter 30 and the second wind power sorter 40 as a light weight product is sent to the fixed amount supply hopper 61 of the volume reducer 60 by the second light weight transfer conveyor 11. The volume-reducing machine 60 compresses and extrudes to form a volume-reduced material, and the volume-reduced material is stored in the volume-reduced material storage unit 13 by the discharge conveyor 12.

The present invention is not limited to the above-described embodiment,
The vibration mechanism of the wind power sorters 30, 40 is directly connected to the mounting plate 35, or the shape of the protruding portion 35b of the mounting plate 35 is not a triangular shape with a sharp top, but a semicircular shape. The top may be rounded. Also, the mounting member 38
It is also possible to change the mounting angle of the machine body 32 by changing the height of 3,384.
If one of 83 and 384 with adjustable height is adopted, the mounting angle can be changed without replacing the mounting members 383 and 384. Further, various modifications can be made such that the non-ferrous metals and other heavy objects may be stored in the same non-ferrous heavy object storage unit as the non-ferrous heavy objects without providing the final selection conveyor 7.

[0026]

As is apparent from the above description,
According to the wind power sorter of the present invention, solid waste in which various solid substances are mixed is thrown in and vibrated on the mounting plate on which the solid waste is mounted, and air is blown from below and in the lateral direction to reduce the weight of plastics and the like. Since objects and heavy objects such as iron and glass are selected, reliable selection is possible even when the lightweight objects are in the form of a film.In addition, the mounting plate can be tilted or flat parts can be attached to the mounting plate. By forming the protrusions or by sloping the through holes of the mounting plate and providing them on the tops of the protrusions, it is possible to achieve more reliable selection. Further, according to the sorting and collecting apparatus of the present invention, the solid waste in which various solids are mixed is sorted into a lightweight object such as plastic and a heavy object such as iron or glass by vibrating. By using the wind force sorter that uses wind pressure in two stages, there is an effect that it can be reliably performed.
