Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waste wire separating and recycling apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste wire separating and recycling apparatus for separating copper wire covered with a resin or the like by crushing a copper wire and coating such as resin and recycling copper wire and cloth.

As the industry develops, the demand for electric wires is increasing in various industries such as electric, telecommunication, and electronics industries. As a result, the amount of generated waste wires is rapidly increasing, and various efforts are being made to regenerate such waste wires.

Such a waste wire is usually arranged such that a copper wire is disposed at the center thereof or a bundle of copper wire is bundled together and a periphery thereof is covered with a resin coating of various materials depending on the purpose.

The copper wire forming the waste wire can be reproduced by itself, and most of the resin coating surrounding it is incinerated. When the resin coating is incinerated, dioxin, which is a carcinogenic substance, is discharged to the atmosphere, causing another type of environmental pollution.

Recently, there has been developed a device for crushing waste wires and selectively recycling the copper wire and the resin coating surrounding the copper wire.

In the case of copper wire, it is selected from waste wires and melted and regenerated. In the case of resin coatings, combustible coatings and non-combustible coatings are selected, and in the case of combustible coatings, pyrolysis is performed to refine them with light oil, heavy oil and gasoline .

Nevertheless, when the resin coating surrounding the copper wire from the waste wire is crushed and then screened, the dry method or the wet method using the difference in specific gravity between them is used. However, there is a limit in the yield of separation between these methods, There is a problem of environmental pollution due to the dust generated during the operation and the problem of harming the health of workers is very high.

Generally, the waste wire from the production process or the construction process is separated by separating the copper wire and the wire cover, then the copper wire is recycled, and a large amount of the wire jacket is incinerated. However, in the process of incinerating the wire covering, harmful substances such as dioxin are discharged to cause environmental pollution problem, and also problems that are not good in terms of energy utilization have occurred.

Accordingly, a method for recycling such a waste wire has been proposed. For example, Korean Patent Publication No. 2000-000311 discloses a method for separating waste wires and waste communication cables.

However, since the above-mentioned conventional waste wire recycling apparatus has to transport the waste wire processed individually by each worker between each step such as the collection step of collecting the waste wire and the crushing step, the work is inconvenient and the productivity is deteriorated .

2 to 4 show a waste wire separation and recycling apparatus according to one preferred embodiment of the present invention.

Referring to FIG. 2, an apparatus for separating and recycling waste wires according to one preferred embodiment of the present invention includes a hopper-type charging unit 10 to which a crushing object such as a waste wire is charged, And a wet type separation and sorting unit 70 for sorting the waste wire crushed material into copper crushed material and resin crushed material by specific gravity difference, .

The construction of the hopper-type charging unit 10 into which the waste wire is charged and the crushing unit 12 for crushing the waste wire charged into the hopper charging unit 10 are well known in the art, It will be able to use its shape appropriately. Therefore, a detailed description thereof will be omitted.

The waste wire charged into the hopper-type charging unit 10 is crushed by the crushing unit 12 well known in the art and then supplied to the crushing supply line 16 via the blower 14 as shown in FIG. To the cyclone dust collecting unit (20).

The pulverized wire wire (the pulverized wire wire and the pulverized wire of the coating material such as the resin are mixed) supplied to the inside of the cyclone dust collecting part 20 flows into the inside thereof, and falls while rotating in friction contact with the inner circumferential surface. For this purpose, the cyclone dust collecting unit 20 is formed in a cylindrical shape on the upper portion thereof, as shown in FIG. 2, and is formed in an inverted conical shape in which the diameter becomes narrower downward.

At this time, a vacuum is formed in the center of the inside of the cyclone dust collecting part 20, and the air in the vacuum space is formed of a relatively clean air layer. This air layer is discharged to the outside through the air blowing line 18 shown in Fig. 2, and the internal pressure of the cyclone dust collecting part 20 is adjusted.

As shown in Fig. 2, the pulverized wire which has dropped while rotating in the state of being in frictional contact with the inner circumferential surface of the cyclone dust collecting unit 20 is subjected to vibration of the diaphragm 64, which is arranged obliquely, The resin crushed material moves upward along the inclined surface of the vibration plate 64 and the resin crushed material having a relatively low specific gravity moves downward along the inclined surface of the diaphragm 64 so that the copper crushed material forming the waste wire and the resin crushed material surrounding the waste crushed material are primarily separated Are selected.

At this time, the diaphragm 64 has a plurality of voids smaller than the size of the copper crushed and / or resin crushed material on its surface, as shown in Fig. 3 in particular, and an air flow is formed upward from the lower portion thereof, The air supply means (62, 62a) are arranged so that the crushed material is floated by the pressure of the air.

Although not shown, the air supply conduit 62 has a structure in which air is supplied by a blower.

The copper particles and the resin particles floated through the air supply nozzles 62a from the outside are sensitive to the vibration of the diaphragm 64 so that they are quickly separated and sorted into copper particles and resin particles.

The copper particles separated and sorted by the dry type separation and sorting section 60 are transferred to and stacked in a primary copper reservoir 54 symbolically shown at 54, And then falls down from the inclined lower portion of the diaphragm 64 to reach the inclined diaphragm 77 disposed therebelow.

At the same time, water is fed downward by the water supply means 72 in the direction of the top surface of the inclined vibration plate 77. At this time, since the inclined diaphragm 77 causes the vibration to the left and right in the drawing by the drive motor 81, the copper crushed material having a relatively large specific gravity moves along the upwardly inclined surface on the right side in the figure, This small resin crushed material moves along with the water along the downward sloping surface on the left side in the drawing.

As shown in Fig. 6, the resin crushed material having a relatively small specific gravity falls along with the water by the sieve, so that water is discharged downward, and the resin crushed material is filtered by the sieve. The resin lumps filtered by the screen are again transported upward along the diagonal diaphragm.
