Description

{RECYCLING SYSTEM FOR WASTE OPTICAL FIBER}

The present invention relates to an optical fiber having an optical fiber layer on which a waterproof tape is wound along the periphery of an optical fiber ribbon to prevent moisture penetration, an inner skin of metal provided along the periphery of the optical fiber layer, Styrene) -container, comprising: a separator for continuously cutting along the longitudinal direction from the outer surface to the inner surface while continuously feeding the charged optical cable; A cutter for cutting the abandoned light cable incised up to the inner skin into a predetermined length while grinding; A mixing hopper for separating the abandoned light cable into an inner layer, an outer layer and an optical fiber layer while retaining the pulverized abandoned light cable of predetermined length for a predetermined time to remove the oil contained in the abandoned light cable; A first separator connected to the mixing hopper through a conveying conveyor and having a PE material shell and an optical fiber layer, and a metal separator; A first dehydrator for removing moisture contained in the outer shell and the optical fiber layer separated through the first separator, and a second dehydrator for removing moisture contained in the inner shell; And a secondary sorting device connected to the first dehydrator through a conveying conveyor for sorting the metal contained in the sheath and the optical fiber layer in the sorting or transferring process.

When compared with conventional coaxial cables, optical cables can transmit a large amount of information quickly, and therefore their use in the transmission of electrical and electronic signals such as computers, TVs, and telephones is vigorous.

A large number of optical fiber ribbons are stacked in the center of the optical cable, and a core wire made of a steel wire or high strength synthetic fiber for protecting the optical fiber ribbon is inserted to correspond to an external force.

In addition, an outer layer of the optical fiber ribbon is formed with a waterproof layer coated with a waterproof tape so as to prevent moisture penetration, and an endothelial layer of a metal material made of aluminum or steel is formed on the outer circumferential surface of the waterproof layer to reduce moisture penetration and external impact. And an outer skin layer made of a material such as poly (styrene) (PE) is formed along the periphery of the inner skin at the outermost layer.

In general, optical fiber cables that are discarded are peeled off the outer surface of a material such as PE in order to be recycled for each type of material. Since the outer surface of the optical cable is firmly pressed around the inner surface, It is not easy to separate. Therefore, when the disposal of such a discarded optical cable is manually performed by using a blade or the like, the workability is very low and the disposal cost of the discarded optical cable is increased.

However, since the outer surface of the optical cable is firmly pressed on the inner surface, the workability of the optical cable is deteriorated, so that a large amount of the waste optical cable is separated from the outer surface of the optical cable. It is difficult to do.

In addition, although it is possible to collect only the inner skin by burning the outer surface of the discarded optical cable, there is a problem of environmental pollution due to combustion of the outer skin, the outer skin can not be recycled, and only the inner skin is recycled.

It is also possible to dissociate the outer skin from the inner skin by dissipating the heat to the melting point of the PE, which is the outer skin, using the electric wire insulation method using the electric resistance heat. However, this method also requires a large amount of separation of the outer skin and the inner skin of the optical fiber cable There is a difficult problem.

First, the stripping machine 100 includes a tubular inlet 101 formed with a predetermined length so as to feed a scrapped cable, an upper roller 110 having a predetermined length rotated through the driving motor M1 in one direction, A lower roller 120 spaced apart from the upper roller by a predetermined distance and rotated in a direction opposite to the upper roller through a driving motor Ml rotating in a direction opposite to the driving motor M1 rotating the upper roller, And continuously transfers the abandoned light cable C injected through the upper roller 110 and the lower roller 120, which are rotated in opposite directions to each other.

The upper roller 110 is formed with a first guide groove 111 formed in a concave shape or a beveled surface so as to be in close contact with the upper outer circumferential surface of the abandoned light cable, And a first cutter blade 112 for cutting along the longitudinal direction.

The lower roller 120 is formed with a second guide groove 121 formed in a concave shape or a beveled surface so as to be in close contact with the lower outer circumferential surface of the obsolete light cable, And a second cutter blade 122 for cutting along the longitudinal direction.

The first cutter blade 112 and the second cutter blade 122 are formed in a disk shape and have a predetermined width so that the cutter blade 120 can be cut from the outer skin 30 of the abatement cable C to the inner skin 20, The first guide groove 111 and the second guide groove 121 are formed at positions corresponding to each other so that when the abscissa cable C passes between the upper roller 110 and the lower roller 120, The first cutter blade 112 and the second cutter blade 122 are pressed between the first guide groove 111 and the second guide groove 121 so that the outer skin 30 and the inner skin 20 are smoothly cut .

Next, the cutter 200 is cut into a predetermined length while grinding the abandoned light cable cut to the inner skin. The cutter 200 includes a main body 210, a cover 220, a first fixed cutter 230, A rotary shaft 240, a rotary shaft 250, and a rotary cutter 260.

A cover 220 is hinged to the upper part of the main body 210 to prevent the abandoned light cable cut off from the inside of the main body 210 from escaping to the outside.

In addition, a discharge port (not shown) for discharging the pulverized abandoned light cable of a predetermined length is formed at one side of the main body, and a conveying conveyor for conveying the abandoned light cable discharged to the discharge port to the mixing hopper is provided. The discharge port may have a width or shape corresponding to a length of a waste cable cut to a predetermined length or less so as to be discharged to the outside or a discharge port having a plurality of discharge holes formed in a width or shape corresponding to the discharge port, So that the abandoned light cable can be discharged to the outside.

The cover 220 is provided with a charging port 221 for charging the abandoned light cable transferred from the removing device 100 into the main body. The input port 221 may be formed in a trumpet shape having a predetermined length so that the abatement cable C can be smoothly inserted into the interior and can be stably inserted into the main body without shaking during the transportation process.

The first stationary cutter 230 has one end fixed to the front side inner circumferential surface of the main body, and the other end has a blade for cutting the abandoned light cable.

The second fixed cutter 240 has one end fixed to the inner circumferential surface on the rear side of the main body, and the other end made of a blade for cutting the optical cable.

Both ends of the rotation shaft 250 are inserted into a bearing 251 provided at both ends of the main body and are rotated through the power of the drive motor 252.

The rotary cutter 260 includes a disk-shaped body 261 fitted to the rotary shaft, and a plurality of blades 262 disposed radially from the outer circumferential surface of the body. The rotary cutter 260 rotates along the rotary shaft, Is continuously cut to a predetermined length.

In addition, the rotary cutter 260 may be configured such that the end of the blade is connected to the first and second fixed cutters 260 and 260 so that the abandoned light cable can be crushed into the inner skin, the sheath and the optical fiber layer in the mixing hopper 300, (230, 240).

The abandoned light cable C is continuously inserted into the main body 210 through the upper roller 110 and the lower roller 120 of the removing machine so that the abandoned light cable C Is cut, the abscissa cable is drawn in a predetermined length toward the rotating shaft until the next blade 262 " (hereinafter referred to as the " second blade ") cuts the abraded cable. Since the second blade 262 'rotates while abutting the ablated light cable C between the first fixed cutter and the second blade, the abandoned light cable C is crushed and crushed between the first fixed cutter and the second blade, do.

It is preferable that the driving motor for rotating the rotating shaft rotates at a speed not too high so that the abandoned light cable can be cut and cut smoothly by the blade of the rotary cutter. If the rotation speed of the driving motor is too high, there is a problem that the time for the abatement cable to be squeezed between the first fixed cutter and the blade can not be ensured, so that it may not be smoothly pulverized. If the rotation speed is too slow, However, since the amount of the abatement cable that can be treated is reduced so much, there is a problem that the working efficiency is significantly lowered.

The present invention is also characterized in that the second fixed cutter 240 is further provided on the inner circumferential surface on the rear side of the cutter main body so as to smoothly move among the pieces of the abandoned light cable C cut between the rotary cutter 260 and the first fixed cutter 230 The crushed pieces can be crushed once more between the rotary cutter and the second fixed cutter and then discharged to be smoothly separated into the outer skin, the inner skin and the optical fiber layer when the mixture is introduced into the mixing hopper at the rear end.

Next, the present invention is characterized in that a plurality of input ports 221 are provided on the cover 220 at predetermined intervals so that a larger amount of abandoned light cable can be crushed and cut per unit time, A plurality of second cutter blades 122 may be provided on the upper and lower rollers 110 and 120 at regular intervals along the longitudinal direction so as to correspond to the input ports. The plurality of rotary cutters 260 may be provided on the rotating shaft.

In addition, when the plurality of rotary cutters are arranged on the rotary shaft so that the abandoned light cable charged into the cutter is smoothly crushed without being sandwiched between the rotary cutter and the first fixed cutter or between the rotary cutter and the second fixed cutter, It is preferable that the blade is staggered with the blade of the adjacent rotary cutter.

When a plurality of rotary cutters 260 are coupled on the rotary shaft so that the blades are staggered with each other as described above, when the abraded-light cable is sandwiched between the blade of the one-side rotary cutter and the first fixed cutter, Since the protruding portion is twisted to the rotary cutter side, it is possible to cut the crushed end portion through the blade of the adjacent rotary cutter, thereby preventing malfunction or breakdown of the cutter.

If a plurality of rotary cutters are coupled to the rotary shaft so that the blades of one rotary cutter are arranged in line with the blades of the adjacent rotary cutter, if the abraded light cable is sandwiched between the blade of one rotary cutter and the first stationary cutter, Even if the end portion of the cable is twisted to the adjacent rotary cutter side, there is no space between the blade of the adjacent rotary cutter and the first fixed cutter, so that the rotation axis can not rotate any more.

In addition, the cover 220 is provided with a plurality of input ports 221. When the plurality of rotary cutters 260 are provided on the rotation axis so that the blades are formed on the same axis, the input ports need to be input at the same timing In addition, when a plurality of abandoned light cables are simultaneously supplied, abandoned light cables having the same or at most similar lengths must be selected for the next process, resulting in a problem that the workability is remarkably deteriorated.

Even if a plurality of rotary cutters 260 are sequentially inserted into the plurality of input ports 221 by engaging with the rotary shaft 250 such that the blades 262 are staggered with each other, It is possible to solve the problem naturally through the arrangement characteristics of the rotary cutter blade even if the abandoned light cable is interrupted.

The pulverized light cable C having a predetermined length while passing through the cutter 200 can be introduced into the mixing hopper 300 through the conveying conveyor and a magnetic belt (not shown) may be provided in front of the conveying conveyor It is also possible to separate the iron component from the inner skin of a metal material and then introduce it into a mixing hopper.

The mixing hopper 300 is filled with a separating liquid consisting of a functional liquid which is easily separated into an endothelium, an outer skin, and an optical fiber layer while removing water and oil contained in the abatement cable.

The separation liquid is composed of 60 to 90% by weight of water and 10 to 40% by weight of a functional liquid.

The functional liquid may be selected from a surfactant or sodium aluminate. For example, the separation liquid may be prepared by mixing 75% by weight of water and 25% by weight of a surfactant. The surface active agent can obtain an effect of cleaning the outer surface of the abandoned light cable. When the foreign matter is applied, the surfactant penetrates between the foreign matter and the external skin to decrease the surface tension, thereby smoothly separating foreign matter. And between the endothelium and the optical fiber layer to act as a lubricant, thereby facilitating the separation.

The mixing hopper 300 is formed in the same shape as the mixer drum of the ready-mixed vehicle and is rotatable in the forward and reverse directions so that the pulverized abandoned light cable can be smoothly separated into the inner skin, the outer skin, and the optical fiber layer. do.

When the mixing hopper 300 has no fluidity, the waste cable is separated only by the chemical separation method using the separation liquid. However, when the mixing hopper has fluidity, the physical separation method is performed in parallel, so that the waste cable is smoothly connected to the outer skin, .

Further, when the mixing hopper 300 rotates in the forward and reverse directions as in the present invention as compared with the method in which the mixing hopper 300 rotates only in one direction, the flowability of the abatement cable is remarkably improved, so that it can be separated more smoothly.

As described above, according to the present invention, since the chemical method for staying the abandoned light cable in the separated liquid for a predetermined period of time and aging, and the physical method for promoting the separation by rotating the mixing hopper in the forward direction and the reverse direction simultaneously, Can be smoothly separated.

The outer shell, the inner skin, and the optical fiber layer separated through the mixing hopper 300 are discharged through the outlet of the mixing hopper and then introduced into the first separator 400 through the conveying conveyor.

The primary separator (400) is a water tank which is opened at the top and filled with water, and is separated into an envelope, an optical fiber layer and an endothelium by a specific gravity separation method. The PE shell and optical fiber layer float on the water, and the metal end caps are submerged in the water, so they are naturally classified according to the material.

A first conveying screw 410 for discharging the outer shell of the PE material floating on the water and the optical fiber layer is provided in the upper part of the inside of the primary sorting device and a second conveying screw 410 for discharging the inner film of the metal material settled in the water A transfer screw 420 is provided.

The outer surface of the PE material and the optical fiber layer discharged through the first conveyance screw 410 are conveyed to the first dehydrator 500 through the conveying conveyor and passed through the dehydrating and drying process (for example, air drying) (600).

The inner skin of the metal (aluminum, iron) material discharged through the second conveyance screw 420 is transferred to the second dehydrator 510 through the conveying conveyor and recycled after dehydration and drying process (for example, air drying).

The secondary sorting machine 600 is for sorting the metals mixed in the sorting operation or the transferring operation through the primary sorting machine 400. In the same way as the primary sorting machine, And a conveying screw for discharging the separated PE and the separated metal may be provided on the lower part and the upper part of one side. The metals selected through the secondary sorting machine are collected as metals and PE-type as PE-type, dehydrated and dried, and then recycled.

According to the present invention as described above, a plurality of first cutter blades and a plurality of second cutter blades are cut along the longitudinal direction of the upper and lower shells and the inner skin of the cable, while passing through the upper and lower rollers, It can be separated into metals and PE from inside of the mixing hopper by crushing by crushing with a rotary cutter inside the cutter, and then sorted by material through the 1st and 2nd sorting machines so that it can be picked up by melting. It is possible to contribute to the protection of the environment by preventing it from being originated and it is possible to smoothly separate into the outer shell, the inner skin and the optical fiber layer by the chemical method and the physical method in parallel within the mixing hopper after the pulverizing operation of the abandoned light cable through the cutter, It can process large quantity of abandoned light cable, which is advantageous in efficiency and economy. have.
