Next, a method of removing the jelly from the communication cable by the device 100 for removing the communication cable jelly according to the preferred embodiment of the present invention will be described. 3 is a flowchart illustrating a method of removing jelly from a communication cable jelly removing apparatus according to a preferred embodiment of the present invention. Hereinafter, the jelly removing method will be described with reference to FIG.

First, the jelly-filled communication cable 151 is cut to an appropriate size. The reason for splitting the cable 151 into an appropriate size is to greatly improve the efficiency of the work so as to obtain high purity copper.

Next, the cable 151 cut into a proper size is stored in the treatment tank 111 by using a conveying belt, a moving vehicle, or the like (S310). At this time, in order to prevent the cable 151 cut to a predetermined size from being discharged through the discharge hole 114 of the treatment tank 111 before or during the execution of the operation, (151).

The process vessel 111 is provided inside the housing unit 101 so that the door 133 opened in the opening part of the housing unit 101 is opened prior to the above process S300. The opened door 133 is provided on the side of the housing part 101 and it is necessary to adjust the inclination of the treatment bath 111 to accommodate the cable 151 in the treatment bath 111 (S305). The air pump 124 injects air and then the motor 123 and the shaft 122 are driven according to the pressure provided by the air pump 124 during the tilt adjustment of the treatment tank 111.

It should be noted that the door 133 may be formed at the upper end of the housing part 101 in the embodiment of the present invention.

Thereafter, the opened door 133 is closed, and the treatment tank 111 is returned to the upward position (S315). Thereafter, the first through third processes according to the present invention are sequentially performed.

First, the first process is performed (S320). The first step is a step of removing jelly by using a dissolver at a high temperature and a high pressure. To this end, the dissolving agent is introduced through the dissolver inlet 102 and the heating unit 137 is driven (S320a). The internal temperature formed inside the housing part 101 by the heating part 137 in the embodiment of the present invention is 100 ° C. to 200 ° C. If it is required to remove the polyethylene (PE) resin from the cable 151, The unit 137 sets the internal temperature at this time higher than the above case. Meanwhile, in the embodiment of the present invention, any one of water, a base oil, and a mixture of a polyethylene resin and a jelly component is used as a dissolver.

Then, the jelly is firstly separated from the cable 151 for a predetermined time. After a predetermined period of time, the jelly is discharged to the outside together with the dissolving agent through the discharge valve 132 (S320b). Normally, jelly will float in water when separated from copper, and copper will tend to sink into water, so step S320b is quite possible.

Next, the second process is performed (S325). In the second step, the cleaning agent and the solvent for dissolving the cleaning agent are introduced and the jelly is removed using the rotation of the treatment tank 111. To this end, the treatment vessel (not shown) 111) and a solvent (S325a). In the embodiment of the present invention, a conventional detergent and water are used as a cleaning agent and a solvent, respectively. In the embodiment of the present invention, the temperature of the solvent is set to be somewhat lower than the boiling point of water. The temperature of the solvent may be adjusted in advance, but it is also possible to increase the temperature by driving the heating unit 137 to make it suitable. On the other hand, it is also possible to put the washing solution in the second step without adding the washing agent and the solvent.

Thereafter, the adjustment unit is adjusted to rotate the treatment bath 111 (S325b). In step S325b, the solvent, detergent, jelly, etc. are discharged to the outside through the discharge valve 132 (S325c). On the other hand, it is also possible to adjust the inclination of the treatment bath 111 by using the adjustment unit prior to step S325b. After the inclination of the treatment tank 111 is adjusted as described above, the steps S325b and S325c may be performed to increase the efficiency of jelly separation by applying pressure to remove the jelly in various directions.

Next, the third process is performed (S330). The third step is a process of removing jelly by using steam. To this end, the steam generator 104 is operated (S330a). Then, the steam generated in the steam generator 104 is injected in the direction of the cable 151 through the steam outlet 105 (S330b), and the jelly that has not been removed by the steam is separated from the cable 151 . Step S330b is performed for a predetermined time. After the elapse of the predetermined time, the jelly removed through the discharge valve 132 is discharged to the outside (S330c).

The above-described three steps (the first step to the third step) are generally performed in order, but the present invention is not limited thereto. It is also possible to carry out two steps or three steps at the same time. The three processes according to the present invention effectively remove the jelly separation in the cable 151 to obtain much higher purity copper than the conventional method.

It will be apparent to those skilled in the art that various modifications, substitutions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. will be. Therefore, the embodiments disclosed in the present invention and the accompanying drawings are intended to illustrate and not to limit the technical spirit of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments and the accompanying drawings .
