DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the method and apparatus of the embodiment of the present invention will be explained. FIG. 1 shows the steps of the method of the present invention and the apparatus used in each step. In FIG. 1, the process numbers are circled and shown in each block. In FIG. 1, the shredder dust step 1 includes a shredder dust supply device (for example, a hopper or the shredder itself). The shredder dust has a composition as shown in FIG. 2 and contains about 11% of dust of asphalt sheet (laid on the floor of an abandoned vehicle). Asphalt sheet dust has a viscous screen, trommel,
Since it causes the clogging of the crusher, it must be removed in the previous process of those devices. Therefore, the iron powder generated in the shredder stage is adhered to the asphalt sheet dust, which is sticky due to heat generated during shredding by the shredder or heating. In the eddy current classification step 2 of FIG. 1, an eddy current classification device is arranged, and this device separates magnetic materials and non-magnetic materials from non-ferrous metals such as Cu, Al and brass into three parts. The asphalt sheet dust to which the magnetic substance is attached is treated as a magnetic substance and separated and removed together with the iron dust.

Asphalt sheet dust was removed,
Dust containing resin, rubber, glass, wire harness, and non-magnetic stainless steel is sent to the sieving step 3 where it is separated into dust with a size smaller than a predetermined value (for example, 15 mm) and dust with a size larger than the predetermined value. To be done. In the sieving step 3, the sieve 30 shown in FIG. 3 is arranged. The sieve 30 has, for example, a sieve element 31 in which square eyes each having a side of 15 mm arranged in a grid pattern are connected to each other, and is rotated by a chain-driven sprocket 32.
The pan 33 receives dust having a size equal to or smaller than a predetermined value that has passed through the zeros, and the container 34 receives dust having a size that exceeds the predetermined value and has not passed through the eyes of the sieve 30. Dust having a size of a predetermined value or less mainly includes glass, resin, and rubber dust,
It is sorted in the order of 6 and 7. Further, the dust having a size exceeding the predetermined value mainly includes wire harness, resin, rubber, non-magnetic stainless steel, and relatively large glass dust, and is sorted in the order of steps 8, 9, 10, 11, and 12. .

Dust having a size less than a predetermined value is passed through a rotary sieve (Trommel 40) in step 4, and rubber and resin dust finer than the size k of Trommel's eyes and dust larger than the size of eyes (glass is here). It is included). Trommel 40, as shown in FIG.
Cylinder with many holes 41 (holes) on the wall
With a sieve that is rotated around the axis with an inclination of -10 °, dust is put in from one end, fine dust passes through the eye 41 and falls, is received by the pan 42, and other dust is received from the other end of the trommel 40. It comes out and is received by the receiving container 43.

Dust larger than the trommel eye size k is sent to step 5, and a slide type sorter 50 is used to make the dust more slippery (glass dust and some resins) and dust less slippery ( Rubber and the rest of the resin). As shown in FIG. 5, the slide-type sorter 50 supplies dust to the upper part of an inclined slide (iron plate) 51 and causes it to slide down by its own weight, which has good slipperiness and mainly dusts containing glass dust. Receive in the receiving container 52,
The container 53 is configured to receive dust including rubber, resin dust, and the like, which have a low slidability and fall nearby. A relationship of 0.1 ≦ k / j ≦ 0.5 is established between the size k of the trommel and the size j of the sieve in the step 3. The reason is that if k / j is smaller than 0.1, the trommel may be clogged.
This is because the recovery rate of glass dust decreases when j exceeds 0.5.

Dust mainly containing glass dust is sent to the permeation separation step 6 and is separated into transparent glass dust and resin, rubber, and colored glass dust by using the permeation type separator 60. As shown in FIG. 6, the transmission type sorting machine 60 includes a hopper 61 for supplying dust, a dust aligning device 62 including an electromagnetic vibration feeder for aligning the dust, and a belt 63 for transporting the aligned dust at an appropriate speed. A light source 64 provided on one side of the dust path flying away from the end of the belt 63, and a CCD camera 65 provided opposite to the light source 64 on the opposite side of the dust path from the light source 64;
An air gun 66 provided on the downstream side of the D camera 65 in the dust flow direction, an air nozzle 67 provided on the downstream side, and a non-transparent dust receiving container 68 provided so as to face the air gun 66.
And a transparent glass dust container 6 provided on the most downstream side
It consists of 9 and. The CCD camera 64 determines whether the dust is highly transparent (transparent glass dust) or low in transparency (resin, rubber, colored) based on the intensity of light passing through the dust from the light source 64. (Glass dust) is determined, and when the dust has low transparency, air is instantaneously ejected from the air gun 66 to receive the non-transparent dust in the container 68. In the case of transparent glass, the air gun 66 does not eject air.

When the size of the dust becomes fine, it becomes difficult for the CCD camera 65 to judge the transparency of the dust. Therefore, the air with a small force is constantly ejected from the air nozzle 67 to remove the fine dust from the dust flow path. This prevents the non-transparent fine dust from entering the transparent glass dust receiving container 69, and improves the purity of the transparent glass dust. Thus, step 7
The transparent glass dust obtained in step 1 has high purity.

Dust having a size exceeding a predetermined value is processed in Step 3.
Sent to step 8. Specific gravity separation is performed in step 8,
It is classified into dust such as glass having a large specific gravity and non-magnetic stainless steel, and dust such as a wire harness, resin and rubber having a small specific gravity. In step 8, a specific gravity sorter 80 is arranged. As shown in FIG. 7, the specific gravity sorter 80 includes a vibrating and tilting sieve 81 and a blower 8 for sending wind from below.
And 2. The wind of the blowing unit 82 may be turbulent. Dust having a large specific gravity is caught on the vibration sieving sieve 81 and moves to the upper side by vibration, and dust having a small specific gravity is lifted by the wind from the vibration sloping sieve 81 and moves to the lower side of the vibration sieving sieve 81, so that both can be separated. .

The dust containing the wire harness, resin and rubber is sent to the crushing step 9. In step 9, the wire harness is separated into a core wire and a covering material by crushing, and the covering material, other resins, and rubber are extruded through the eyes of the crusher to be granulated. In step 9, the crusher 90 shown in FIG. 8 is installed. Crusher 9
Reference numeral 0 has a fixed blade 91, a rotary blade 92, and a screen 93. The fixed blade 91 and the rotary blade 92 crush the wire harness to separate it into a core wire and a covering material. Further, the coating material, the other resin, and the rubber are heated by crushing, and are granulated when passing through the eyes 94 of the screen 93,
It becomes a granular material. The core wire remains elongated. There is a relationship of 0.1 ≦ z / j ≦ 0.5 between the size z of the screen 93 of the crusher 90 and the size j of the sieve of step 3. The reason is that when z / j is smaller than 0.1, the screen is clogged, and when z / j is larger than 0.5, the crushing function is lost.

The dust containing the core wire and the resin and rubber particles crushed in step 9 is sent to step 10 where it is vibrated and sieved to remove the dust mainly containing the core wire and the resin and rubber particles. It is separated into contained dust. As shown in FIG. 9, the vibrating and sieving machine 100 installed in the step 10 has a plurality of elongated rectangular eyes 101. The eye 101 is shown in FIG.
All the eye directions may be arranged in the same direction as shown in (a) of FIG. 9, or the eye direction of one group and the eye direction of another group may be arranged as shown in (b) of FIG. The eyes may be arranged so as to be different from each other, or the eyes of a plurality of groups having different eye directions may be combined and arranged as shown in FIG. If the length of the long side of the eye 101 is x and the length of the short side is y, the shape and size of the eye are determined so as to have a relationship of 0.02 ≦ y / x ≦ 0.3. The reason for setting this range is x when y / x becomes smaller than 0.02.
Is larger and the sieve is bent, and when y / x is larger than 0.3, y is large, and at the same time as the copper wire, the resin and the rubber granules fall under the sieve, and the purity of the copper wire is lowered. Further, the plate thicknesses t and y of the sieve are set to 0.2 ≦ t / y ≦ 5 in order to prevent the copper core wire from being entangled. Further, the relationship between the diameter z of the screen mesh 94 of the crusher in the previous step 8 and y of the vibrating screen is set to 0.1 ≦ y / z ≦ 0.5. The reason is that when y / z is smaller than 0.1, the copper wire does not flow under the sieve of the vibrating sieving machine 100, and when y / z is larger than 0.5, resin and rubber flow into the sieve and the copper This is because the purity of the wire is reduced.

The core wire of the wire harness in step 10 and the dust of fine resin and rubber flowing under the sieve together with the core wire are sent to the specific gravity separation step 11 and are separated in specific gravity in step 11 to obtain a core wire having a large specific gravity (copper). ), A resin having a small specific gravity, and rubber particles. In step 10, a vibrating tilted sieve type specific gravity separator 110 is arranged. This specific gravity sorter 110, as shown in FIG.
11, a blowing means 112 for sending air from the lower side of the vibrating tilted sieve 111, a blowing means 112 and the vibrating tilted sieve 111
And a laminarization means 113 which is disposed between the blasting means 112 and makes a laminar flow of air from the blower means 112, and causes the oscillating inclined sieve 111 to flow.
Consists of The laminarization means 113 is composed of, for example, a rectifying plate having a honeycomb structure, and has an air flow Reynolds number of 300.
0 or less, preferably 2500 or less. By providing the laminarization means 113 in this way, the air that has passed through the wire mesh of the vibration slanting screen becomes a laminar flow, and the lightweight resin and rubber dust can be effectively floated away from the wire mesh, and thereby the heavy core wire The accuracy of separation is increased, and the purity of the core wire (copper) collected separately can be increased. As a means of reducing the Reynolds number, there is a method of heating air to increase the viscosity of the air.

Further, the vibration slanting screen 111 in the step 11
As shown in FIG. 11, is composed of a crosspiece 114 and a wire net 115 stretched over the crosspiece 114. The crosspiece 114 is a vibrating inclined sieve 11
1 extends in the vibrating direction, which prevents the core dust from being caught in the crosspiece, which has occurred in the conventional type in which the crosspiece extends in the direction orthogonal to the vibration direction. Therefore, the classification is smoothly performed.

When the shredder dust having the components of FIG. 2 (shredder dust of an abandoned automobile) is used for fractionation according to the process of FIG. 1, glass dust having a purity of 99.6% is obtained in the process 7, and the process 12 As a result, a copper wire having a purity of 99.3% was obtained. To attach the iron powder (magnetic material) to the asphalt sheet dust, use a hammer-type shredder machine to hit the scrap car body and parts with a hammer.
The iron powder generated during shredder was attached to the asphalt sheet dust. Also, due to frictional heat during shredding, the dust increased to 50 to 100 ° C., so the asphalt sheet dust was also softened and the tackiness was further increased.
Iron powder became easier to adhere.

The conditions of each step and the separation state were as follows. In the eddy current fractionation in step 2, 85% of iron, 95% of asphalt sheet dust, 90% of aluminum and 60% of brass were excluded. Further, the thermoplastic resin also increased in tackiness due to heat, and 35% was eliminated. When a square sieve having a side length j of 15 mm was adopted as the sieve of Step 3, the weight ratio of dust having a size of more than 15 mm and dust having a size of 15 mm or less was 1: 8. Step 4
The sieve used had a diameter of 5 mm. 5 mm
The ratio of the dust having a size exceeding 5 to the dust having a size of 5 mm or less was 7: 3 by weight. The rotation speed of the rotary sieve was 10 RPM. The glass purity after the slide type fractionator 50 in step 5 was 85%. Transmission type sorter 6 in step 6
The glass purity after 0 was 99.6%. A halogen bulb was used as the light source 64. 90% of the colored glass was blown off by the air gun 66. The wind speed of the air nozzle 67 is 3 ~
It was set to 5 m / sec.

In step 8, the wire harness, resin, rubber side and discharge side such as stainless steel have a separation ratio of 8: 2.
Met. The same sorter as that without the laminarization means 113 in step 11 was used. The frequency was 10 Hz and the amplitude was 5 mm. In step 9, the eyes 94 of the screen 93
The diameter z of the blade is 5 mm and the rotation speed of the rotary blade 92 is 400 RP
M. The shape of the sieve in step 10 was the type (a) in FIG. The size of the sieve mesh is x 10m
m and y were 1 mm, and the thickness t was 2 mm. The purity of the copper wire after vibrating and sieving was 70%. Frequency is 10Hz,
The amplitude was 5 mm. The Reynolds number by the laminarization means 113 of the specific gravity sorter 110 in step 11 is 2500, and the crosspiece 1
The direction of 14 was the vibration direction. The purity of copper wire after separation is 9
It was 9.3%. As a comparative example, when the direction of the crosspiece was made orthogonal to the vibration direction, the purity of copper was lowered to 82%. However, the frequency was 10 Hz and the amplitude was 5 mm. In this way, highly accurate automatic sorting has become possible, and the shredder dust that had previously been landfilled has been utilized as a resource, and it has become possible to extend the life of a shortage of landfill. .
