Description

Technical Field

[0001] This utility model relates to the field of cable recycling technology, and in particular to a cable loose wire recycling device based on multi-stage sorting. Background Technology

[0002] Cable recycling is an important resource recycling effort. It aims to extract metals (such as copper and aluminum) and plastics from waste cables through scientific processing, thereby achieving resource recycling and reducing environmental pollution.

[0003] However, traditional cable recycling devices based on multi-stage sorting mostly focus on recycling metal materials in the cables, ignoring the impurities and dust that adhere to the cables during use. As the recycling process proceeds, some impurities will adhere to the metal components, making sorting difficult and causing trouble for subsequent cleaning after recycling.

[0004] For example, cable strands need to undergo a pre-treatment process before recycling. During the pre-treatment process, the crushing device will strip the cable strands, causing the internal metal components to separate from the outer sheath. In the process of separating and stripping, impurities (these impurities are mud and dirt that the cable gets into during outdoor installation, which are highly adhesive and difficult to clean) are also mixed with the metal impurities and the separated outer sheath, and need to be treated separately. Utility Model Content

[0005] This utility model discloses a cable loose wire recycling device based on multi-stage sorting, which aims to solve the technical problem that traditional cable loose wire recycling devices based on multi-stage sorting mostly focus on recycling metal materials in the cables, ignoring the impurities and dust that adhere to the cables during use. As the recycling process proceeds, some impurities will adhere to the metal components, which not only makes sorting difficult, but also causes troublesome cleaning after subsequent recycling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable loose wire recycling device based on multi-stage sorting includes a first support frame, a second support frame, and a third support frame. A screen shaking frame is installed at the bottom of the first support frame. A magnetic separator and a conveyor frame are respectively installed at the top of the second and third support frames. A discharge platform is also provided at the top of the first support frame. The device further includes: a cleanup mechanism: the cleanup mechanism includes a screen plate hinged to the inner wall of one side of the screen shaking frame. Return springs are provided on both sides of the bottom outer wall of the screen plate. Two support blocks are provided at the bottom of the screen shaking frame. The bottom ends of the two return springs are respectively connected to the tops of the two support blocks. A pneumatic vibrator is also provided at the bottom of the screen plate. A central protrusion is provided at the center of the top outer wall of the screen plate. Dispersing protrusions are provided at equal intervals on both sides of the top outer wall of the screen plate. Equally spaced perforations are opened between two adjacent dispersing protrusions on the same side of the screen plate; a magnetic separation mechanism: the magnetic separation mechanism is located at the end of the screen plate; and an eddy current separation mechanism: the eddy current separation mechanism is located at the end of the magnetic separation mechanism.

[0008] In this scheme, the raw material added through the feeding platform is pre-treated cable strands. The impurity removal mechanism is mainly used to remove dust and impurities mixed in with the various components after the outer sheath is peeled off. In the sieve plate specifically set in this scheme, the raw material from the feeding platform is first dispersed by the central convex plate, and then fed under the sieving and shaking action of the sieve plate. During this process, the multiple dispersing convex plates located on both sides of the central convex plate can play a slowing effect, reducing the speed at which the mixed components fall, and at the same time, it can make the mixed components collide more violently when crossing the dispersing convex plates, thereby more effectively cleaning out dust and impurities, and facilitating the efficient separation of subsequent conductive metal materials.

[0009] In a preferred embodiment, the magnetic separation mechanism includes a magnetic separation drum mounted on a second support frame. A first motor is mounted on one outer wall of the second support frame. One end of the output shaft of the first motor is connected to one end of the magnetic separation drum. The second support frame is also provided with equally spaced trays, and the tops of several trays support the same first collection box.

[0010] The magnetic separation mechanism features a magnetic separation drum that operates in the opposite direction to the sieve plate. The magnetic structure inside the drum attracts ferrous conductors from the mixture. As the drum rotates away from the magnetic structure, the attracted ferrous conductors detach from the drum and fall into the first collection box. Other components that have been shaken off at the end of the sieve plate are then transported to the conveyor frame by gravity for further sorting. This process, characterized by slow and dispersed sieve operation, allows for more accurate and thorough magnetic separation of ferrous conductors.

[0011] In a preferred embodiment, the eddy current sorting mechanism includes a conveyor frame disposed on top of the third support frame. The top of the conveyor frame is provided with two conveyor rollers, and the two conveyor rollers are connected to the same conveyor belt. A second motor is disposed on one side of the outer wall of the conveyor frame, and one end of the output shaft of the second motor is connected to one of the conveyor rollers. A second collection box is disposed on one side of the conveyor frame. A sorting ramp is disposed on one side of the top outer wall of the second collection box. An eddy current sorting roller is disposed inside the conveyor roller near the sorting ramp. A baffle is disposed on one side of the outer wall of the second collection box, and a groove is formed on the side of the baffle near the second collection box.

[0012] The eddy current separation mechanism can be used to magnetically separate materials such as copper and aluminum, excluding iron. The magnetic attraction structure inside the eddy current separation drum is different from the fixed setting in the magnetic separation mechanism. The internal eddy current separation drum is rotating. The disordered magnetic field will provide a reverse repulsive force on the passing metal conductor. Relying on this repulsive force, the copper and aluminum conductors in the mixture can be pushed into the second collection box, thus completing the screening of metal conductors.

[0013] As described above, a cable loose wire recycling device based on multi-stage sorting includes a first support frame, a second support frame, and a third support frame. A screen shaking frame is installed at the bottom of the first support frame, and a magnetic separator and a conveyor frame are respectively installed at the top of the second and third support frames. A discharge platform is also provided at the top of the first support frame. The device further includes: a cleanup mechanism: the cleanup mechanism includes a screen plate hinged to the inner wall of one side of the screen shaking frame. Return springs are provided on both sides of the bottom outer wall of the screen plate. Two support blocks are provided at the bottom of the screen shaking frame, and the bottom ends of the two return springs are respectively connected to the tops of the two support blocks. A pneumatic vibrator is also provided at the bottom of the screen plate. A central protrusion is provided at the center of the top outer wall of the screen plate, and equally spaced dispersive protrusions are provided on both sides of the top outer wall of the screen plate. Equally spaced perforations are opened between two adjacent dispersive protrusions on the same side of the screen plate; a magnetic separation mechanism: the magnetic separation mechanism is located at the end of the screen plate; and an eddy current separation mechanism: the eddy current separation mechanism is located at the end of the magnetic separation mechanism. The cable loose wire recycling device based on multi-stage sorting provided by this utility model has the technical effect of improving the sufficiency of sorting and facilitating direct recycling.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] The cable loose wire recycling device disclosed in this utility model is mainly applied to the traditional cable loose wire recycling device based on multi-stage sorting. In use, most of them only focus on recycling the metal material in the cable, ignoring the impurities and dust that adhere to the cable during use. As the recycling process proceeds, some impurities will adhere to the metal components, which not only makes sorting difficult, but also causes trouble for subsequent cleaning after recycling.

[0022] Reference Figure 1 , Figure 2 and Figure 3A cable loose wire recycling device based on multi-stage sorting includes a first support frame, a second support frame, and a third support frame. A screen shaking frame 3 is installed at the bottom of the first support frame. A magnetic separator 4 and a conveyor frame 8 are respectively installed at the top of the second and third support frames. A discharge platform 1 is also provided at the top of the first support frame. The device also includes a cleanup mechanism: the cleanup mechanism includes a screen plate 13 hinged to the inner wall of one side of the screen shaking frame 3. Return springs 22 are provided on both sides of the bottom outer wall of the screen plate 13. Two support blocks 21 are provided at the bottom of the screen shaking frame 3. The bottom ends of the two return springs 22 are respectively connected to the top of the two support blocks 21. The bottom of the screen plate 13 is also provided with a pneumatic vibrator 19. A central protrusion 14 is provided at the center of the top outer wall of the screen plate 13. Dispersed protrusions 15 are provided on both sides of the top outer wall of the screen plate 13 at equal intervals. There are equally spaced perforations 20 between two adjacent dispersed protrusions 15 on the same side of the screen plate 13. Magnetic separation mechanism: The magnetic separation mechanism is located at the end of the screen plate 13. Eddy current separation mechanism: The eddy current separation mechanism is located at the end of the magnetic separation mechanism.

[0023] In practical use, the raw material added through the feeding platform 1 is pre-treated cable wire. The impurity removal mechanism is mainly used to remove dust and impurities mixed in with the components after the outer skin is peeled off. On the screen plate 13 specifically set in this scheme, the raw material from the feeding platform 1 is first dispersed by the central convex plate 14, and then fed under the screening and shaking action of the screen plate 13.

[0024] During this process, the multiple dispersing protrusions 15 located on both sides of the central protrusion 14 can slow down the flow of the mixture, reduce the speed at which the mixture descends, and allow the mixture to collide more violently when it crosses the dispersing protrusions 15, thereby more effectively cleaning out dust and impurities.

[0025] The top of the feeding platform 1 is equipped with a hopper 2. Both the feeding platform 1 and the hopper 2 are set vertically downward. The screen shaking frame 3 is an inclined structure. The included angle between the screen plate 13 and the feeding platform 1 is 110°-120°. The set included angle range can ensure that the screen plate 13 and the feeding platform 1 are more stable and not steep. With the slow-speed structure of the dispersing convex plate 15, impurities can be screened and shaken out more fully.

[0026] In addition, the top of the central convex plate 14 is a angular protrusion structure, and the top of the dispersing convex plate 15 is a rounded protrusion structure. The height of the central convex plate 14 is twice the height of the dispersing convex plate 15. The central convex plate 14 is used to separate the mixed loose lines of batch feeding, ensuring that both sides can be processed separately. The dispersing convex plate 15 can be adjusted slowly, and together with the set leakage holes 20, it can more efficiently leak impurities.

[0027] Reference Figure 2In a preferred embodiment, a mounting frame 16 is installed at the bottom of the sieve shaker 3, and a third collection box 17 is slidably connected to the inner wall of the mounting frame 16. The third collection box 17 is located directly below the sieve plate 13, and a first handle 18 is provided on one outer wall of the third collection box 17.

[0028] In actual use, the third collection box 17 can be used to collect the impurities screened off by the impurity removal mechanism. Considering that the processing batch is not large, this solution mainly relies on the third collection box 17 for collection. In actual use, if the processing batch is too large, centralized collection and bagging can be adopted for transportation, which is more convenient for collection.

[0029] Reference Figure 1 and Figure 4 In a preferred embodiment, the magnetic separation mechanism includes a magnetic separation drum 4 mounted on a second support frame. A first motor 5 is mounted on one outer wall of the second support frame. One end of the output shaft of the first motor 5 is connected to one end of the magnetic separation drum 4. The second support frame is also provided with equally spaced trays 6, and the tops of several trays 6 support the same first collection box 7.

[0030] Specifically, the magnetic separation drum 4 in the magnetic separation mechanism can be in the opposite direction to the sieve plate 13. The magnetic attraction structure inside the magnetic separation drum 4 is used to attract the iron conductor in the mixed components. As the magnetic separation drum 4 rotates to the side away from the magnetic attraction structure, the attracted iron conductor will detach from the magnetic separation drum 4 and fall into the first collection box 7 for collection. Other components that are shaken off at the end of the sieve plate 13 can enter the conveyor frame 8 under the action of gravity for subsequent sorting. Because the sieve process is slow and dispersed, the iron conductor can be magnetically separated more accurately and fully.

[0031] Reference Figure 1 , Figure 4 and Figure 5 In a preferred embodiment, the eddy current sorting mechanism includes a conveyor frame 8 disposed on the top of the third support frame. The top of the conveyor frame 8 is provided with two conveyor rollers 27, and the two conveyor rollers 27 are connected to the same conveyor belt 9. A second motor 10 is disposed on one side of the outer wall of the conveyor frame 8. One end of the output shaft of the second motor 10 is connected to one of the conveyor rollers 27. A second collection box 11 is disposed on one side of the conveyor frame 8. A sorting inclined plate 28 is disposed on one side of the top outer wall of the second collection box 11. An eddy current sorting roller is disposed inside the conveyor roller 27 near the sorting inclined plate 28. A baffle 12 is disposed on one side of the outer wall of the second collection box 11. An inclined groove 26 is opened on the side of the baffle 12 near the second collection box 11.

[0032] Specifically, the eddy current separation mechanism can be used to magnetically separate materials such as copper and aluminum, excluding iron. The magnetic attraction structure inside the eddy current separation drum is different from the fixed setting in the magnetic separation mechanism. The internal eddy current separation drum is a rotating setting. The disordered magnetic field will provide a reverse repulsive force on the passing metal conductor. Relying on this repulsive force, the copper and aluminum conductors in the mixture can be pushed into the second collection box 11, thus completing the screening of metal conductors.

[0033] It should be noted that the baffle 12 can block the metal conductor and allow it to enter the second collection box 11 stably. During this process, the inclined groove 26 on the baffle 12 can also play a guiding role.

[0034] Reference Figure 5 In a preferred embodiment, there is a gap between the sorting sloping plate 28 and the conveyor belt 9, and a fourth collection box 25 is provided on one side of the bottom outer wall of the conveyor frame 8. The fourth collection box 25 is located below the gap, and the bottom of the fourth collection box 25 is provided with a moving wheel. A second handle is provided on one side of the outer wall of the fourth collection box 25.

[0035] It should be noted that in the mixed components, the outer sheath material other than the metal conductor will enter the fourth collection box 25 through the gap. The fourth collection box 25 can be transferred by means of moving wheels, so that the collected plastic sheath is uniformly transferred, collected and recycled. Relying on multi-stage sorting, the recycled cable wires are fully recycled and reused.

[0036] Working principle: In use, the pre-treated loose mixture is first added to hopper 2 (this addition can be achieved by a feeding conveyor belt, controlling the feeding speed to feed hopper 2, which is convenient for slow screening and shaking with screen plate 13). Under the action of pneumatic vibrator 19, screen plate 13 will continuously maintain high-frequency vibration to screen and shake the mixture from the discharge platform 1. During this process, the central convex plate 14 can disperse the raw material from the discharge platform 1, and then discharge it under the screening and shaking action of screen plate 13. Multiple dispersing convex plates 15 located on both sides of the central convex plate 14 can slow down the speed of the mixture falling, and at the same time, allow the mixture to collide more violently when crossing the dispersing convex plates 15, thereby more effectively cleaning out dust and impurities. The subsequent magnetic separation mechanism can remove iron components from the mixture, and the eddy current separation mechanism can remove conductive metals such as copper and aluminum from the mixture. The remaining surface material will fall into the fourth collection box 25 through the gap for collection.

[0037] It is particularly important to note that the broken cables processed in this solution have a lot of mud and dirt that has been detached during the crushing process (the dirt and dirt cannot be removed from the cable sheath by the cleaning mechanism alone). However, this mud and dirt is mixed with various components, and the cleaning mechanism in this solution is designed to treat this type of mud and dirt.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
