The treatment system 1 of the pulverizing residue shown in Fig. 1 possesses: screening plant 20, and it is as screening installation pulverizing residue 10 being screened the pulverizing residue 10a below into given size and pulverizing residue 10b more than given size; Iron class removing production line 3, its from screened go out given size more than pulverizing residue 10b except de-iron class; Nonferrous metal removing production line 5, it is from the pulverizing residue 10c eliminating iron class, further removing nonferrous metal class; Pulverizer 7, its be by the given size after eliminating iron class and nonferrous metal class more than pulverizing residue 10d be ground into screening plant 20 given size below reducing mechanism; Feeding device 9, it is that the pulverizing residue 10a being ground into below given size and the pulverizing residue 10e that is ground into below given size is dropped into the used device dissolving stove to gasification.
Originally, pulverize residue 10 namely to foam ammonia (base) formic acid (second) ester, synthetic resin, fiber, metal species, glass, wirning harness etc. containing, for example the material trade waste disintegrating machines such as abandoned car being carried out break process as described above.Pulverize the treatment system 1 of residue to possess: the platform 51 born the lorry 50 being mounted with that pulverizing residue 10, will residue 10 be pulverized be fed into the funnel (ホ Star パ) 60 of the treatment system 1 pulverizing residue.And, between funnel 60 and screening plant 20, be configured with the conveyer belt (コ Application ベ ア) 71 for the pulverizing residue 10 be fed in funnel 60 being delivered to screening plant 20.In the present embodiment, conveyer belt 71 is band (belt) formula conveyer belts, but as long as can conveying crushing residue 10, is not limited to tape conveyor belt, can adopts the various conveyer belts such as chain conveyor.
Screening plant 20 the pulverizing residue 10 being fed into funnel 60 is carried out according to its size the device that screens.Specifically, be the screening plant of so-called cylinder sieve-type (ト ロ Application メ Le) as shown in Figure 2.That is, screening plant 20 possesses the inclination angle with about 3 ~ 10 ° and the swing roller of the cylindrical shape rotatably configured (De ラ system) 21, simultaneously swing roller 21 side face break-through and be formed with the hole portion 23 of multiple given size.And, pulverize residue 10 and swing roller 21 is rotated if drop into from the input port 26 of the other end being arranged on swing roller 21, then the pulverizing residue 10 passing hole portion 23 below hole portion 23 diameter dimension and falling.They are collected by funnel 29a and become the pulverizing residue 10a of below given size.In addition, the pulverizing residue 10a below this given size filtered out directly is fed into not shown aerification by feeding device 9 and dissolves stove and process.
On the other hand, pulverizing residue 10b more than given size discharges from the outlet 27 of end face of the opposite side being arranged at swing roller 21, becomes the pulverizing residue 10b of more than given size.Pulverizing residue 10b more than given size is transported to iron class removing production line 3 after being collected by funnel 29b.

Secondly, the treatment system 1 pulverizing residue has nonferrous metal class removing production line 5, carries out the removing of nonferrous metal class from the pulverizing residue 10c eliminating iron class further.The removing of nonferrous metal class is, such as, processed by the pulverizing residue 10c eliminating iron class by not shown rod mill or ball mill, resin or glass are by thinner all to pieces, due to its extensibility ductility, area increases metal species, therefore can be distinguished by not shown sieve.In addition, replacement sieve processes also can operate by hand to these and screens, and then also can direct operation by hand distinguish and remove nonferrous metal class from the pulverizing residue 10c eliminating iron class.
Secondly, the treatment system 1 the pulverizing residue pulverizing residue 10d possessed more than by the given size eliminating iron class and nonferrous metal class carries out the pulverizer 7 pulverized.Pulverizer 7 to by nonferrous metal removing production line 5 eliminate iron class and nonferrous metal class after given size more than pulverizing residue 10d more carefully pulverize, thus pulverizing is, below the size identical with the pulverizing residue 10a below the given size filtered out by above-mentioned screening plant 20.In the present embodiment, the size of size and below the 40mm screened with screening plant 20 is ground into.The downstream of nonferrous metal removing line 5 possess to removed by nonferrous metal line 5 remove nonferrous metal class after pulverizing residue the 10d funnel 63, the conveyer belt 74 that the pulverizing residue 10d supplied from funnel 63 is delivered to pulverizer 7 that drop into, thus, pulverize residue 10d and be fed into pulverizer 7.In pulverizer 7, when carrying out reducing volume owing to pulverizing, the frictional heat that produces and shear heat can remove the moisture pulverized and contain in residue 10d, and volume also can be compressed to about about 1/3.And, by pulverizer 7 be crushed to below 40mm pulverizing residue 10d and by the pulverizing residue 10a that screening plant 20 screens, be fed into not shown melting furnace by feeding device 9 together and process.
Secondly, a just embodiment of processing method of pulverizing residue preferably involved in the present invention and the action of the treatment system 1 of above-mentioned pulverizing residue, is described in the lump.
First, pulverizing residue 10 lorry 50 after carrying out break process with the trade waste of disintegrating machine to the abandoned car containing foaming ammonia (base) formic acid (second) ester, synthetic resin, fiber, metal species, glass, wirning harness etc. etc. is transported to platform 51 and drops into funnel 60, and start process (operation S0).
Pulverizing residue 10 conveyer belt 71 being fed into funnel 60 is delivered to screening plant 20, is that benchmark carries out screening (operation S1) with given size by pulverizing residue 10.Screening plant 20 is screening plants of cylinder sieve-type, and pulverize residue 10 if drop into and swing roller 21 is rotated, then the pulverizing residue 10a passing hole portion 23 below the diameter dimension in the hole portion 23 established in side break-through falls, and is collected by funnel 29a.On the other hand, pulverizing residue 10b more than given size discharges from the outlet 27 of swing roller 21, is collected and be transported to iron class removing production line 3 by funnel 29b.In addition, screening here, is preferably set as diameter 40mm by the size in the hole portion 23 of screening plant 20, is that boundary is screened with 40mm.Thus, as described above compared with prior art, the treating capacity of the pulverizing residue 10 of about 10 ~ 20% can be increased.
Then, pulverizing residue the 10b more than given size distinguished by screening plant 20 is sent to iron class removing production line 3.That is, pulverizing residue the 10b more than given size distinguished by screening plant 20, is transported with conveyer belt 72 and is carried out iron class removing (operation S2) by magnetic separator 3a.
Pulverizing residue 10c after eliminating iron class by magnetic separator 3a is then delivered to vibrating scalper 4, sorts out the residue such as rubber and resin by vibrating scalper 4.The residues such as the lighter rubber contained in pulverizing residue 10b more than dress given size on a vibration table and resin are induced to downside, are induced by upstream side containing nonferrous metal residues such as copper.Thus, carry out the classification that grade is higher.
Pulverizing residue 10c except de-iron class carries out the removing (operation S3) of nonferrous metal class further.The removing of nonferrous metal class, such as, also with not shown rod mill or ball mill process or can carry out handwork.
