Further, FIG. 2 is a schematic view of the sorting table when viewed from above. As shown in these figures, the present device 1 includes an inclined sorting table 2, a vibration generating device 3 that gives vibration to the sorting table 2, and a water supply device 4 for supplying water to the sorting table 2. In the electric wire waste collecting device provided, the sorting table 2 has a side wall member 22 and a weir member 23 for blocking the water supplied by the water supply device 4 and at least one of the sorting table 2 on the table body 21. A partition plate 24 for partitioning the miscut material recovery passage 242 and the main sorting passage 241 is provided in the vicinity of the side wall member 22 of the main sorting passage 241, and a large number of convex portions 2411 are formed in the main sorting passage 241. It is a thing. In addition to the above, the device 1 includes a wire scrap throwing device 5 for throwing wire scraps into the sorting table 2, and a collecting container 6 for collecting metal conductors and covering materials discharged as a result of sorting. ing.

As is clear from the description described later, the present device 1 can separate and recover metal conductors and covering materials such as copper materials contained in crushed wire scraps by utilizing the difference in specific gravity thereof. Is. More specifically, water is flowed from the water supply device 4 to the upper surface 211 of the diagonally inclined sorting table 2, and the sorting table 2 is vibrated diagonally upward (inclined direction) while being placed on the sorting table. By throwing in the crushed wire waste, these can be separated by utilizing the difference in specific gravity between the metal wire and the coating material in the wire scrap, and the metal wire such as copper can be recovered with high quality. In particular, the apparatus 1 can recover a metal lead wire such as a high-purity copper material with a high recovery rate. The metal lead wire to be recovered by the present device 1 is not limited as long as it can be separated and recovered by utilizing the difference in specific gravity, and can be applied to various metals such as copper, aluminum, and gold. Further, the coating material contained in the electric wire waste of the present device 1 and to be recovered is not limited as long as it can be separated and recovered by utilizing the difference in specific gravity, but a polymer material, specifically, Is generally rubber or resin, and is preferable. In the case of resin, specific examples thereof include, but are not limited to, polyvinyl chloride, polyethylene and the like.

First, the present apparatus 1 includes a sorting table 2 having an inclined upper surface 211 formed as described above. The inclined sorting table 2 is a main member of the present device 1, and the vibration generator 3, the water supply device 4, the electric wire waste input device 5, the collection container 6, and the like are all arranged around the sorting table 2. The material of the sorting table 2 is not particularly limited, but it is preferable that the entire material is a metal such as stainless steel in that hardness and prevention of water leakage can be efficiently ensured.

Further, the sorting table 2 is provided with a side wall member 22 and a weir member 23 for blocking the water supplied by the water supply device 4 in the table main body 21, and further, by providing the partition plate 24. The upper surface 211 of the base body 21 can be divided into a main sorting passage 241 and a miscut material recovery passage 242. The sorting table 2 is provided with a support member 25, and the support member can maintain a predetermined inclination and position.

As is clear from the above description, the base body 21 of the sorting table 2 is a member forming the main skeleton of the table, and the upper surface 211 of the table body 21 is scrapped (metal lead wire and covering material). Will come into contact and move. The base body 21 also functions as a bottom when water is supplied and filled with water.

Further, as described above, the weir member 23 in the sorting table 2 is a member used for blocking water together with the side wall member 22, and is provided on the inclined upper surface in a direction (width direction) intersecting the inclined direction. It is a member. The height of the weir member 23 is not particularly limited as long as water can be stored to a desired height, but is preferably in the range of 5 mm or more and 20 mm or less, and more preferably in the range of 10 mm or more and 15 mm or less.

Further, the side wall members 22 in the sorting table 2 are formed on both sides of the table body 21 in the sorting table 2 and function as a wall for preventing water from leaking and wire scraps from spilling. The height of the side wall member 22 may be such that water does not leak and electric wire waste does not spill, and is preferably in the range of 5 mm or more and 50 mm or less, for example. The width of the sorting table 2 and the distance between the side wall members 22 are appropriately adjusted and not limited depending on the amount of electric wire waste processed and the like, but are generally preferably 30 cm or more and 100 cm or less.

Further, the partition plate 24 in the sorting table 2 is a plate arranged substantially parallel to the wall surface formed by the side wall member 22, and as described above, the main sorting passage 241 near the center and the miscut material recovery passage from the end. The area can be divided into 242. The specific principle and its effect of dividing the passage will be clarified from the description described later, but the partition plate 24 enables higher quality separation and recovery. In the example of the present device 1, two partition plates 24 are provided, a main sorting passage 241 is provided in the center, and two miscut material recovery passages 242 are provided on both sides thereof. Each of the partition plates 24 is provided with a portion bent so as to approach each other (the main sorting passage 241 is narrowed) in the vicinity of the lower end. By doing so, it is possible to separate and collect higher quality wire waste.

The inclination angle of the sorting table 2 (more specifically, the inclination angle of the upper surface) can be appropriately adjusted and is not limited depending on the specific gravity, weight, etc. of the target electric wire waste and the covering material, but is not limited to, for example, 2. The degree is preferably 20 degrees or more, and more preferably 3 degrees or more and 10 degrees or less.

In addition, a large number of convex portions 2411 are formed in the main sorting passage 241 of the sorting table 2. A specific image of the effect of the convex portion 2411 is shown in FIG. This figure is an image view when the convex portion 2411 is viewed from the side. In the present device 1, by providing a large number of convex portions 2411 on the sorting table 2, it is possible to prevent the above-mentioned agglomeration that may occur due to the introduction of electric wire waste. Specifically, even when the covering material or the like is wrapped in a metal lead wire and put into a lump in a state where it is put into a sorting table or after being put into a lump, it is given by the vibration generator 3. The lump is lifted by the vibration, and the lump collides with the convex portion 2411 to be surely loosened, and the covering material and the metal lead wire can be efficiently separated and collected separately. More specifically, the collision position between the lifted mass and the convex portion and the angle thereof greatly differ depending on the position of the convex portion and the convex portion. As a result, since the direction and strength of the impact applied to the lump are significantly different from those in the case where there is no convex portion and is smooth, the lump can be impacted from various angles and the lump is easily loosened. Of course, according to this convex portion 2411, the same separation and recovery effect can be obtained even for a so-called miscut material in which the metal lead wire and the coating material remain adhered even in the crushing step.

As is clear from this point of view, it is preferable that a large number of convex portions 2411 are arranged while forming a gap. By providing a gap in the convex portion 2411, it is possible to separate the wire waste without hindering the smooth movement of the wire waste by passing the wire waste through the gap while receiving the impact of a large number of convex portions 2411. Further, it is preferable that the positions of the gaps of the large number of convex portions 2411 are different in the width direction if the inclination direction is different. By doing so, it is less likely that the gap between the convex portions 2411 penetrates in the inclined direction and exists, and the mass can be reliably collided with the convex portion and moved while being loosened.

The gaps between the numerous convex portions are not limited as long as the functions of the present device can be exhibited, but are preferably in the range of 1 mm or more and 5 cm or less, more preferably 3 cm or less. is there. Within this range, the lump can be reliably applied to the protrusions, and there is less risk of hindering the smooth movement of wire waste.

Further, the shape of the convex portion of the main sorting passage 241 is not limited as long as it has the above functions, but is round (FIG. 4 (a)) and elliptical (FIG. 4 (b)) when viewed from above. )), A polygonal shape that may include a curved portion (FIG. 4 (c)), etc., and a particularly elongated elliptical shape is also a shape that exists as an existing commercially available striped steel plate. From the viewpoint, it is preferable because it is easy to introduce. An image of these convex portions is shown in FIG.

Further, when the shape of the convex portion 2411 is a shape other than the round shape and has an extension shaft (long axis) (as in the cases (b) and (c) in the above figure), the extension shaft is , It is preferable that the sorting table is arranged so as to be one by one or a plurality of the sorting table alternately opposite to the tilting direction. By doing so, the mass is subject to collision / impact in a plurality of directions, which has the effect of making it easier to loosen.

Further, in the convex portion 2411, the length of the extension shaft (the longest distance of the convex portion along the extension axis) is not limited as long as it has the above function, but is preferably 5 mm or more and 10 cm or less. , More preferably 5 cm or less. Within this range, the effect of efficient mass separation can be obtained, and there is little risk of hindering the smooth movement of wire waste collection.

Further, the height (maximum height) of each of the large number of convex portions 2411 is not limited because it can be appropriately adjusted depending on the size of the wire waste that is crushed and thrown in, but is not limited to 0.5 mm or more and 3 mm. The following is preferable. By setting this range, the height at which the lumps collide with each other is surely set, and the wire scraps can get over the convex portion, so that the wire scraps can move smoothly. Further, as shown in the above figure, it is preferable that the cross section of the convex portion is not a rectangle but a so-called mountain shape having an inclination in which the height changes from the peripheral portion to the apex portion. By doing so, it is possible to provide an inclination, and this inclination makes the mass bounce back in various directions, making it easier to unravel.

Further, in the present device, the formation of a large number of convex portions 2411 may be configured to directly form the convex portions on the surface of the base main body portion of the sorting table, but a large number of convex portions are formed on the base main body portion. It may be formed by arranging a striped steel plate. By doing so, when it is desired to change the shape of the convex portion, it can be changed simply by replacing the so-called striped steel plate, and maintenance becomes easy. An image in this case is shown in FIG. Further, in this case, it is preferable to have a slope for eliminating the step between the steel plate surface and the upper surface of the sorting table so that a step between the steel plate surface and the upper surface of the sorting table is not generated, or a configuration in which a depression is formed by the thickness of the steel plate. The installation of the steel plate is not particularly limited, but it is preferable to fix the steel plate to the sorting table with a claw, a screw, or the like so that the steel plate does not float due to vibration.

Further, as is clear from the above description, the present device 1 includes a vibration generator 3 that gives vibration to the sorting table. The vibration generator 3 is not limited as long as it has this function, but as shown in FIG. 1, for example, a power device 31 that causes rotation of a motor or the like, a pulley 321 that transmits the rotation of the power device, and the pulley 321 thereof. It has a transmission member 32 such as a belt 322 wound around the belt, and a vibration generating member 33 that gives vibration to an inclined table based on the movement of the transmission member.

The direction of vibration generated by the vibration generator 3 in the present device 1 is not limited, but is either the vertical direction or the direction from the vertical direction to the inclined direction (direction toward a higher position). Is preferable. By doing so, a force that moves in the direction can be applied to the wire scraps, and smooth movement and efficient separation are possible. Further, in this case, the amplitude of the vibration generated by the vibration generator 3 is not particularly limited, but is preferably 1 mm or more and 5 mm or less. Further, the frequency of vibration can be adjusted as appropriate, and is preferably 1 Hz or more and 100 Hz or less. Within this range, the wire scraps can be efficiently separated and collected in combination with the convex portion.

Further, as described above, the present device 1 includes a water supply device 4 for supplying water to the sorting table 2. The water supply device 4 is not limited as long as the function of the device 1 can be exhibited, but the pump 41 connected to the water source, the pipe 42 connected to the pump and guiding the water, and the water supply device 4 are used. It is preferable to have a water supply member 43 connected to the pipe 42 to supply water. The water supply member 43 has a configuration in which water discharge holes are formed at predetermined intervals in one direction so as to be in a so-called shower state in order to irradiate the sorting table 2 with water more widely and uniformly. It is preferable to have.

Further, the present device 1 includes an electric wire waste throwing device 5. As is clear from the above description, the electric wire waste input device 5 is provided fixedly above the upper surface of the sorting table, and can drop crushed electric wire waste little by little to the sorting table. is there. The structure is not limited as long as it can perform the above functions, but a container having a relatively wide receiving port for receiving wire scraps and having a narrower width or diameter toward the bottom and this container. It is preferable to have a discharge mechanism provided inside for discharging a predetermined amount within a certain period of time. In this way, it becomes possible to collect electric wire waste more efficiently.

In addition to the above configuration, the apparatus 1 is provided with a collection container 6, which is provided on the upstream side and the downstream side of the sorting table 2, respectively, and further, the downstream side is the main sorting passage 241 and the miscut material. It is provided in each of the collection passages 242. As a result, it becomes possible to collect the separated and separated electric wire waste for each type. The collection container 6 may be any container as long as it can collect electric wire waste, but since the electric wire waste is discharged together with water, at least the bottom of the collection container 6 provided on the downstream side is an electric wire. It is preferable that the cable is shaped like a so-called colander in which a large number of holes for draining water are formed while being able to retain waste. It is also preferable from the viewpoint of resource saving and utilization that the discharged water is recovered as it is and supplied to the water supply device again. Of course, in this apparatus 1, no additive is used for separation in principle, so that the load on the environment is low.

Next, here, the method of collecting electric wire waste by the present device 1 will be specifically described including the operation of the present device 1.

First, the user throws the crushed electric wire waste into the electric wire waste input device 5 of the present device 1, operates the water supply device 4, and starts supplying water to the sorting table 2 especially the main sorting passage. .. At the same time, the vibration generator 3 is also operated to generate vibration for the sorting table 2. In this case, the wire scraps are finely crushed and contain a metal lead wire such as copper and a covering material adhering to the periphery thereof, and further, as a miscut material in which the metal lead wire and the covering material remain adhered. It is included, and also includes a metal wire and a covering material in a lump.

Then, the electric wire waste throwing device 5 is operated, and a fixed amount is thrown into the sorting table 2. The coating material contained in the charged crushed material is resin waste, which has a lower specific gravity than water, so that it floats on water and moves below the sorting table by the water flow. On the other hand, since the metal lead wire such as copper contained in the charged crushed material has a higher specific gravity than water, it settles and comes into contact with the upper surface of the sorting table, and the vibration applied to the sorting table acts in this state. , Move the metal lead wire above the sorting table. Utilizing this phenomenon, resin scraps are separated from crushed wire scraps and copper materials are recovered.

By the way, the crushed product is not sufficiently crushed, and the crushed product (hereinafter referred to as miscut material) in which some resin waste is attached to the copper material or the like, and the metal lead wire and the coating material are lumps. In the above-mentioned copper recovery device, how to separate and recover the miscut material and the lump is a big problem.

On the other hand, in this device, a convex portion is provided in the main sorting passage, and the miscut material and the lump are impacted in various directions and positions in the convex portion. While unraveling, the covering material separated as a result of unraveling moves below the sorting table, and the metal lead wire moves in the inclined direction (upward) of the sorting table. It should be noted that the miscut material, which was difficult to separate even in this convex portion, is moved closer to the side portion because it is difficult to move perpendicularly to the flow of water supplied by the water supply device, and is moved to the side portion. It moves upward in the miscut material collection passage provided and is collected.

As described above, according to the present invention, it is possible to provide an electric wire waste collecting device capable of collecting higher quality metal conducting wires.

The present invention has industrial applicability as an electric wire waste collecting device and an electric wire waste collecting method.
