In the first processing method shown in (1), plastics having a high material composition weight of home electric appliances are landfilled or incinerated as dust. As a result, there is a major problem that a large amount of limited and valuable resources (fossil fuels) are wasted.

の篩いに絡み機能を低下させる。A second problem is that a relatively large size non-ferrous metal part is crushed and then crushed by a wind separator 5.
Can be sorted into dust group and non-ferrous metal, but copper wire for motors and compressors used in home appliances and internal wiring and power cord using copper wire are easily entangled and light, so about 50mm ~ 100mm In the wind separation device 5 for separating the crushed material by the wind, most of the crushed materials are mixed into the dust group and discarded. Furthermore, some of the copper wires that have been wind-sorted to the non-ferrous metal side are crushed and finely cut, and then sieved and sorted.

阻害する問題があった。As a result, in most home appliances except for some home appliances having a heat exchanger, most of the copper used is occupied by the copper of the motor, the internal wiring, and the power cord. In addition, there is a problem that the recovery rate of copper having a high level is extremely low, and also a problem that the sieving function of the sieving and sorting machine 6 is obstructed.

た。Further, in order to sort and recover the copper wire mixed in the dust by vibration separation, it is necessary to make the crushed size extremely fine. However, the dust group of home electric appliances has a problem in that the thermoplastic resin occupies a large part and thus has poor heat conduction, and the heat during crushing causes the thermoplastic resin to melt and cannot be crushed.

Even if the crushed plastic contains many water-repellent substances until it becomes compatible with water, even if the styrene resin b is mixed with the olefin resin a and the conditions are appropriately set, the sorting accuracy is 95%.
% Was the limit. On the other hand, in order to increase the processing capacity of water specific gravity sorting, when the amount of plastic input to the water specific gravity sorting machine is increased, plastics overlap with each other, and what is supposed to sink will be sandwiched by floating things Sorting accuracy decreases.

As a result, the mixing accuracy is remarkably deteriorated because it is mixed with the olefin resin a.

When re-contaminated by the method, when the selected polypropylene resin is re-pelletized, thermal degradation of the plastic is caused by the catalytic action of the metal, or oxidation degradation occurs during long-term use. Further, the screen of the extruder at the time of repellet is clogged, which causes a problem in mass production.

In other words, a closed system requires a large installation space and a large-sized device, which increases the cost of recycling and is not practical.

In addition, there is a problem that the ion exchange resin of the ion exchange tower must be periodically regenerated, which leads to complications and a cost for regeneration.

線が回収できない問題がある。The second problem is that, similarly to the first processing method, since the crushed material of the internal wiring and the power cord is easily entangled and light, the crushed material crushed to 50 mm to 100 mm is separated into a light-weight material separating apparatus. When separated at 13, a considerable amount enters the dust group and is discarded. In addition, copper wires such as motors and compressors and some of the internal wiring and power cord crushed materials from the previous process are sent to the metal separation process 16, but copper wires with extremely small surface area other than copper and aluminum blocks are used. Since it is extremely difficult to separate the non-ferrous metal by the eddy current separator 19, the non-ferrous metal is sent to the next step together with the plastic group, and there is a problem that the copper wire cannot be recovered.

脂を回収することができる。The film of the multilayer capacitor is obtained by depositing aluminum on a PET film, and has a higher melting point than that of a polypropylene resin. Therefore, the screen of the extruder is clogged at the time of repellet processing, and the productivity is remarkably deteriorated. In addition, if different materials are mixed, the physical properties deteriorate or black spots and the like are generated on the surface of the molded product.However, by separating and collecting an ultralight material e of a foam such as a film of a multilayer capacitor or styrofoam, the repellet processing is performed. It is possible to recover a polypropylene resin that reduces the productivity, decreases the physical properties, and reduces the contamination of the surface of the molded product with foreign substances that cause contamination.

源も有効に利用できる。As described above, according to the first aspect of the present invention, the first raw material supply means for supplying the crushed waste home appliances or the crushed waste and the sorting water is provided. A first water-specific-gravity sorting device that sorts the raw material from the raw material supply means into at least two types of crushed materials based on a specific gravity difference of the crushed materials, and a light-weight material among the crushed materials sorted into the at least two types. First supply means for supplying the sorting water to the subsequent process, and a centrifugal force acting on the light-weight material and the sorting water sent from the first supply means to separate the crushed material submerged in water and the crushed material floating in the water again A second water-specific-gravity separator, and a selected-water circulating means for circulating the selected water used in the second specific-gravity separator upstream of the first water-specific-gravity separator. In the sorting device, the specific gravity of the crushed waste home appliances is greater than 1.0 and A crushed material which is a heavy object, the less the crushed material having water repellency larger than a specific gravity of 1.0, is selected to sink side. On the other hand, since only the crushed material floating in the water whose total amount has been reduced by the first water-specific gravity separator is supplied to the second water-specific gravity separator on which the centrifugal force acts, centrifugation is performed in a state where the overlap between the crushed materials is small. In the water specific gravity selection in which the force G acts, separation is initially performed due to water repellency, or because air bubbles are attached or air is retained inside like sponges (combined foam sponge). Crushed materials that could not be obtained can be separated with high accuracy. As a result, the polypropylene resin from which the crushed material that should originally sink is separated and removed can be collected, so that a material suitable for material recycling can be provided. Further, since the water specific gravity separation device is provided with the separation water circulation means, water resources can be effectively used.

It is possible to collect copper wires and aluminum pieces as heavy-weight materials without previously removing components including copper wires such as power cords and internal wiring. As a result, it is possible to easily collect copper wires and small pieces of non-ferrous iron, which have been difficult to sort by conventional methods such as wind power sorting and eddy current. Further, since the crushed material submerged in water can be sorted into a heavy specific gravity material and a medium specific gravity material, the value of the heavy specific gravity material can be increased. Further, since the mixing of metal into the medium specific gravity can be reduced, it can be provided as a raw material for partially replacing coke as a blast furnace reducing material, or as a substitute material for boiler fuel.

る。According to the third aspect of the present invention, the second water-specific-gravity sorting device includes a rotating drum having a rotation center axis in the vertical direction and containing the sorting water inward, and a rotating drum of the rotating drum. A cylinder provided on a rotation center axis for supplying a mixture of crushed material and sorting water into the rotary drum; first recovery means on a bottom side of the rotary drum; and second recovery means on an upper portion of the rotary drum Means, the light-weight objects floating on the water supplied from the water-specific gravity separation device at the preceding stage to the second water-specific gravity separation device have 800G.
Since a very strong centrifugal force can be applied, high-precision and high-speed sorting can be performed. Further, since a dehydrator can be provided integrally with the rotating drum, dehydrated polypropylene resin can be collected. Further, since the vertical centrifugal water-specific-gravity separator (the rotation center axis of the rotating drum is in the vertical direction), imbalance hardly occurs at the start and stop of the operation, and a vibration damping device for rotational vibration is not required. As a result, the dehydrated polypropylene resin having high sorting accuracy can be recovered, and can be immediately provided for repellet processing. In addition, the vertical centrifugal water-specific-gravity sorting device can improve the processing capacity of water-specific-gravity sorting, and can save space in the waste home appliance recycling processing device.

燃焼用途に応じて中比重物を得ることができる。According to the fourth aspect of the present invention, between the first water-specific-gravity separator and the second water-specific-gravity separator,
One or more water-specific-gravity separators (third to n-th water-specific-gravity separators) for separating at least two types of crushed materials based on the difference in specific gravity of the crushed materials are provided. Since a second supply means for supplying a light-weight material and sorted water to the specific gravity sorting device is provided, the second water specific gravity sorting device is provided from the first water specific gravity sorting device via the third to n-th water specific gravity sorting devices. Since the light-weight materials floating in the water are supplied, the medium-specific-gravity separator that has been mixed in the water-specific-gravity separator at the preceding stage of the second water-specific separator gradually becomes mixed due to factors such as hydrophobicity or adhesion of bubbles. As a result, the amount of crushed material supplied to the next-stage specific gravity separator is reduced. As a result, a polypropylene resin having extremely high sorting accuracy can be recovered from the second water specific gravity sorting device. In addition, by separating the collection of the crushed material submerged in the water discharged from each water specific gravity sorting device, it is possible to collect medium specific gravity materials having different mixed amounts of heavy specific gravity. As a result, a medium specific gravity can be obtained according to a combustion application such as a blast furnace reducing material and a boiler fuel.

The surface of the crushed material is washed, and at this time, the wettability of the surface of the crushed material is also improved. As a result,
When supplied to the next-stage water-specific-gravity sorting device in a finely crushed state, crushed materials are less likely to entangle or overlap with each other, and the water wettability of the surface is improved, so that the sorting accuracy can be improved. In addition, since the surface of the crushed material is washed, it is possible to reduce the intrusion of foreign matter into the polypropylene resin.
