Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a separating apparatus for separating copper, a covering material and jelly from a waste communication line,

The present invention relates to an apparatus and method for separating copper, cladding material and jelly from waste communication lines by applying a cryogenic cooling system.

There has been a lot of waste communication lines and waste wires every year due to the replacement of old communication lines and the disposal of electronic products. In particular, Korea Telecom (KT) plans to collect copper cable (Jelly Cable) over the next 10 years from 2012 according to the collection plan of the waste communication line which overlaps with the optical cable. Meanwhile, since the communication line encloses a copper wire made of copper (21) with a covering material (22) (see also an enlarged view of FIG. 1), the amount of copper that can be extracted from a communication line to be discarded is 450 thousand tons It is expected to reach.

High-purity high-purity copper wire or aluminum wire is used for wire and communication wire because electric resistance is low. These communication lines are usually covered with a covering material such as polyethylene (PE, PP, PVC) in order to avoid damage due to external exposure or leakage. That is, each of the copper wires used in the cable is coated with a coating material having a thickness of 1 mm or more to manufacture a thin and long communication line, and then these communication lines are consolidated into a bundle so as to prevent the communication line from being damaged from external impact, It is impregnated with jelly made of highly viscous material as a polymer compound and then packed so as to be waterproof. The communication line waterproofed and immersed in jelly is called jelly line. Therefore, in order to extract expensive copper from waste communication lines, especially jelly lines, copper, cladding and jelly should be separated. Korean Patent Application No. 2003-0070086 discloses a method in which a waste paper conveyed on a conveyor is conveyed along a conveying direction and is molten in a sedimentation tanks containing waste cooking oil to dissolve and separate the covering material of waste paper, The present invention proposes a separating and collecting device for waste communication lines using waste cooking oil which allows only copper wire to be separated and recovered by a conveyor at the exit side. Korean Patent Application No. 2006-0040992 also discloses a device for increasing the separation rate between copper and waste wires A separation plate having a separation distance for increasing the mutual separation rate of copper and pulsed electric wires according to the electrostatic capacity of the electrodes, Discloses a electrostatic separation system for removing particulate copper from an electrical wire covering . However, this method can be used when separating copper from ordinary communication lines or wires, but it can not be applied to a jelly line which is waterproofed by being bundled after impregnating the jelly in the communication line. The reason for this is that the jelly used in the waste communication line is a pollutant-causing substance, so it should be separated into designated waste and treated with care. Currently, there are cleaning methods and incineration methods. The cleaning method is to clean the jelly with organic solvent (toluene, thinner, acetone, etc.) first, dry it, then peel off the copper, but this method uses organic solvent and there is a risk of fire and explosion. There is a problem that a health problem occurs due to the exposure, and the copper is oxidized by the organic solvent during the washing process, resulting in discoloration and deteriorating the product value. On the other hand, the incineration method has a problem in that the processing cost is high, the loss rate of copper is high, and the separated copper is discolored due to high heat, thereby deteriorating the product value.

Therefore, there is a need to develop a technology that can economically recover high-purity copper from waste communication lines, especially jelly lines, without discoloring. It is also necessary to collect the covering material and the jelly wrapping the wire so as not to cause pollution.

The above problem is solved by taking into consideration that copper, cladding material and jelly are frozen at a cryogenic temperature, cutting a waste communication line into a piece of waste communication line, rapidly freezing the waste piece of waste communication line with liquid nitrogen and crushing it with a cutter, And jelly dust, and then separating the copper pieces, the cover material pieces and the jelly dust using a separator.

According to the apparatus and method for separating copper, cladding and jelly from the waste communication line of the present invention, the cryogenic cooling system is used to separate and collect jelly which is classified as copper and cladding material, So that it can be recycled. It is also possible to produce high calorific solid fuel by adding charcoal and dioxin reducing agent to the residues of the coverings and jellies.

Furthermore, since pollutants or waste residues that are inevitably generated in the process of treating the waste communication line are not discharged at all, the concern of environmental pollution can also be eliminated.

The present invention is based on the idea that the jelly is frozen at a cryogenic temperature. The waste communication line is cut into a piece of waste communication line by a cutter, and the waste piece of the waste communication line is cooled with liquid nitrogen and then pulverized by a pulverizer to obtain copper pieces, And separating the copper, the covering material and the jelly dust using a separator. Hereinafter, this will be described in detail with reference to the drawings. In principle, the same names and symbols are used for devices having the same function among the devices of the present invention.

1 to 3 are views showing a first embodiment of the present invention. FIG. 1 is a side view of an apparatus for separating copper and a covering material from a waste communication line, FIG. 2 is a perspective view showing an internal structure of the sorter, and FIG. 3 is a plan view .

First, the collected waste communication line is cut to a length of 10 to 60 mm in the cutter 10 to be made into a piece of waste communication line 20, and the waste communication line is transferred to the cooling storage unit 100 using the conveyor 11.

The cutter 10 is a machine used for cutting objects in the industry. The cutter 10 can be installed integrally with the copper and cover material separating apparatus 1 of the present invention or can be installed separately to cut the waste communication line, And the cut waste communication line piece 20 may be transferred to the cooling storage unit 100. FIG.

As shown in FIG. 1, the copper and cladding material separating apparatus 1 comprises a waste paper piece 20 filled with liquid nitrogen (LN), cut into a length of 10 to 60 mm in the cutter 10, LN) and freezes to the inside; The conveying means 210 is installed inside the pipe or the inside of the crusher 300 to form a piece of waste communication line 20 which is frozen in the cooling storage unit 100 by using the conveying means 210. [ A conveying unit 200 for conveying the toner image to the recording medium; The pulverizing means 340 is installed inside the pulverizing means 340 and the pulverized communication line pieces 20 transferred through the transferring means 200 are pulverized to a volume of 0.5 to 3 mm using the pulverizing means 340, (Hereinafter referred to as " dust "); And a sorter (400) for sorting the copper pieces, the pieces of covering material and the dusts, which have been pulverized in the pulverizer (300), by using the vibration separator (420).

The frozen jelly is dust in the frozen jelly when the frozen jelly is transported to the shredder 300 in the frozen state in the frozen state in the cooling storage part 100. The frozen jelly is dusted to form a piece of copper and a covering material, (400).

A liquid nitrogen inlet 110 for introducing the liquid nitrogen LN is formed on one side of the cooling storage unit 100 so that the liquid nitrogen is supplied from the liquid nitrogen storage tank LN can be introduced into the cooling storage unit 100 to be charged. Therefore, when the waste piece 20 of the waste communication line transferred from the cutter 10 is settled in the liquid nitrogen LN, the waste piece 20 of the waste communication line is frozen to the inside and is easily broken by impact.

The conveying unit 200 has a pipe or a U shape and the conveying unit 210 is installed inside the conveying unit 200 so that the piece of waste communication line 20 is conveyed to the crusher 300 by the conveying unit 210. It is effective to use a screw for the conveying means 210.

The pulverizer 300 is a device for pulverizing the pulverized communication line piece 20 refrigerated and frozen in the cooling storage unit 100 into a volume of 0.5 to 3 mm and separating the pulverized product into a copper piece and a cover material piece. There is provided a crushing means 340 for crushing the waste communication line fragments 20. The pulverizing means 340 is composed of a body 341 and a blade 342 so that the pulverized communication line piece 20 is pulverized to a volume of 0.5 to 3 cm to form a piece of copper and a covering material and dust. Since the slice 20 is frozen to the inside, it can be pulverized to a finer size, that is, a volume of 0.5 to 3 mm, without difficulty by impacting with the heavy pulverization means 340. As described above, the jelly in the frozen state is further finely pulverized and dusted as described above in the process of pulverizing the waste communication line piece 20, and the pulverized copper piece, the covering material piece and the dust are mixed together, And then is transferred to the separator 400. The separator 400 separates the pulverized material from the pulverized material conveying pipe 360 through the discharge net 350 formed at the bottom of the pulverized material conveying pipe 360. [

The discharge net 350 is formed with fine holes so as to pass only fine pulverized material pulverized in a volume of 0.5 to 3 mm. Therefore, since the pulverized material having the above-mentioned size can not pass through the discharge net 350, the pulverized material is pulverized in the pulverizer 300 until the volume becomes 0.5 to 3 kPa while moving around the pulverizer 340.

The pulverized water transfer pipe 360 is closed at one side and the blower I 361 is installed at the closed position and the other side is opened to form a pulverized water discharge port 362, (362) is connected to a pulverized material transfer pipe (370) for transferring pulverized material to the sorter (400). Accordingly, when the pulverized material, that is, the copper pieces, the cover material pieces, and the dust are crushed by the crusher 300, the blower I (361) is operated to blow the wind strongly to transfer the copper pieces, the covering material pieces and dust to the separator The pulverized water is conveyed through the pulverized water conveyance pipe 370 in an instant, that is, for 1 to 5 seconds, and is introduced into the sorter 400 through the mixture inlet 411 and discharged onto the diaphragm 421.

As described above, since the waste piece 20 of the waste communication line has been transferred to the inside in a frozen state, heat is not generated in the ordinary pulverizing process. However, in order to completely reprocess the copper for high-price communication lines, it is necessary to fundamentally block the space for generating heat in the grinding process. A liquid nitrogen inlet 330 through which the liquid nitrogen LN flows into the one side of the crusher 300 and a spraying means 331 through the liquid nitrogen inlet 330 are connected to the crusher 300 Spraying the supplied liquid nitrogen (LN) at -196 占 폚 into the pulverized communication line piece 20 in a mist state can prevent the heat that might otherwise occur during the pulverization of the waste line piece 20 from occurring.

The sorting device 400 is a device for sorting copper pieces, cover material pieces and dusts from a mixture in which the copper pieces crushed, crushed, and the dust particles are mixed and transported by the crusher 300. The sorting device 400 includes a cube A mixture inlet 411 through which a mixture of the copper pieces crushed by the crusher 300 and the clay pieces and dust is introduced is formed in the upper part of the main body 410 which is a chamber of a rectangular parallelepiped, A vibration isolator (420) is provided on the platform (426). The vibration isolator 420 is a rectangular plate type in which holes 421-1 having a diameter of 0.4 mm or less are closely formed and is inclined by 10 to 30 degrees and includes a vibrator (not shown) A diaphragm 421 for separating the piece and the piece of covering material, and a copper piece gathering portion 422 formed at the upper end of the diaphragm 421; A covering material piece meeting portion 423 formed at the lower end of the diaphragm 421 and a diaphragm 421 located directly below the diaphragm 421 and connected to the diaphragm 421 by a connecting member 428, That is, both ends of the diaphragm 421, that is, the copper piece gathering portion 442 and the covering material gathering portion 423, also move upward and downward so that the copper pieces are fed to the copper piece gathering portion 422, A diaphragm support 424 for collecting the covering material piece into the covering material gathering portion 423; A strap 425 connecting both upper portions of the diaphragm 421 and the seat 426 to prevent the diaphragm 421 from rising above a predetermined height; And a blower II (430) installed on the seat (426). The strap 425 is made of leather or nonwoven fabric.

The hole 421-1 may be a quadrangular or hexagonal shape having a side of 0.4 mm or less in addition to the circular shape. The diaphragm 421 is formed to be inclined so as to easily separate the copper pieces and the cover material pieces which are different in weight. That is, after the diaphragm 421 is inclined as described above, the copper pieces and the covering material pieces are placed on the diaphragm 421 and vibrated, so that the heavy copper pieces are collected above the diaphragm 421, . This is like the principle of gathering relatively heavier rice at the top of a rice bowl, and rice flakes and rice bran at a lower height than rice.

A process of separating the copper piece and the covering material piece using the vibration means 420 is as follows.

The vibrator is actuated to vibrate the diaphragm 421 by vibrating the copper piece, the covering material piece, and the dust through the mixture inlet 411 from the crusher 300 through the mixture inlet 411, , The heavier copper pieces move over the slope and the lighter weight pieces of the covering material move down the slope. That is, when the diaphragm support 424 is operated by operating the vibrator, both ends of the diaphragm support 424 move up and down like a seesaw so that both ends of the diaphragm 421, that is, the copper piece meeting portion 422, So that the copper pieces are gathered in the copper piece gathering portion 422 and the covering material pieces are collected in the covering material gathering portion 423. This is similar to the principle of extracting rice with rice as described above. However, since the dust is very small in size, it does not go to either side, but rather drops below the diaphragm 421 and tries to accumulate on the seat. Accordingly, when the dust collector 600 is driven and the blower II 430 is driven to blow the wind gently through the holes 421-1 of the diaphragm 421, the dust is blown by the wind and sucked by the suction force of the dust collector 600, And is sucked into the dust collector 600 through the discharge port 412 and the dust discharge pipe 413.

Copper pieces gathered in the copper piece gathering portion 422 are discharged through the copper piece outlet 414, collected in a copper piece collecting box (not shown), packed and then shipped for recycling. The covering material pieces collected in the covering material gathering portion 423 are also discharged through the covering material discharging port 415, collected in a cover material collecting box (not shown), packed and then shipped for recycling. Combination of charcoal and dioxin reducing agent in the covering material and dust can produce a high-calorie solid fuel, so that pieces of coating material and dust can also be recycled. Therefore, no pollutants or waste residues inevitably generated during the processing of the waste communication line are discharged.

It is preferable that the cooling storage unit 100, the transfer unit 200, the crusher 300, and the sorter 400 are kept at a low temperature in order to eliminate the viscosity of the waste communication line 20. 1, the cooling storage unit 100, the transfer unit 200, the crusher 300, and the sorter 400 are installed in a cold room 500 (not shown) in which refrigeration means (not shown) As shown in Fig.

Next, a process for efficiently separating the copper and the covering material embedded in the waste communication line using the above apparatus will be described.

First, the waste communication line is transported to the cutter 10 and then cut to produce a waste communication line piece 20 having a length of 10 to 60 mm.

Liquid nitrogen LN is supplied from the liquid nitrogen storage tank into the cooling storage unit 100 through the liquid nitrogen supply pipe 150 and the liquid nitrogen inlet 110 and is stored in the cooling storage unit 100.

The waste piece 20 of the waste communication line transferred from the cutter 10 is settled in the liquid nitrogen LN to cool the waste piece 20 of the waste communication line.

The waste piece 20 of the waste communication line cooled in the cooling storage unit 100 is transferred to the crusher 300 through the transfer unit 200 and is input to the crusher 300 through the input port 310.

And the pulverized communication line piece 20 transferred to the pulverizer 300 is pulverized to a volume of 0.5 to 3 cm. As described above, when the pulverized communication line piece 20 is frozen to the inside as described above, it is pulverized to a volume of 0.5 to 3 cm by a crushing impact to form a copper piece and a covering material piece. However, the frozen jelly is finely and in detail, The volume of the pulverized and separated copper pieces, the covering material pieces and the dust are mixed in the pulverizer 300.

When the copper pieces, the covering material pieces and the dust are mixed with each other, the vibration separator 420 is immediately activated when the mixture is discharged to the main body 410 of the sorter 400, so that it is separated into relatively heavy and relatively light covering material and very light dust depending on its weight. The separated copper pieces are collected in a copper scrap collection box (440) and the scrap pieces are collected in a cover material collection box (442). Meanwhile, the dust is sucked and collected by the dust collector 600 through the dust outlet 412 and the dust outlet tube 413.
