Description

Technical Field

[0001] This utility model relates to the field of waste tire resource utilization technology, and in particular to a waste tire steel wire separation device. Background Technology

[0002] With the booming development of the automotive industry, the amount of waste tires generated has also continued to rise. Since waste tires are difficult to degrade naturally, long-term open-air storage can cause environmental pollution and pose safety hazards. Therefore, mechanical recycling methods are often used to convert waste tires into renewable resources to solve the pollution problem. The waste tire recycling process typically includes the following two main stages: 1. Mechanical crushing: Waste tires undergo multi-stage crushing to transform them into a mixture of rubber granules, scrap steel wire, and fibers; 2. Material separation: First, magnetic separation technology is used to recover the scrap steel wire from the mixture, and then air separation technology is used to separate the fibers from the mixture, thereby obtaining pure rubber granules as the final product.

[0003] However, the steel cords in waste tires are difficult to completely separate during magnetic separation after mechanical crushing, resulting in some steel wires remaining in the finished rubber granules. This reduces the purity of the finished rubber granules and leads to a decline in the mechanical properties of recycled products such as reclaimed rubber and modified asphalt made from the finished rubber granules. Utility Model Content

[0004] In view of this, it is necessary to provide a waste tire steel wire separation device that can improve the purity of the finished rubber granules, thereby improving the mechanical properties of recycled products such as reclaimed rubber and modified asphalt prepared from the finished rubber granules.

[0005] This utility model provides a waste tire steel wire separation device, including a screening component and a separation component. The screening component is divided into upper and lower layers. The upper layer is used to transport primary rubber particles after magnetic separation, and during the transportation process, primary rubber particles with a particle size not larger than a predetermined size leak to the lower layer for screening. The lower layer of the screening component has a discharge port for conveying the small-diameter rubber particles obtained by screening to the separation component. The separation component includes a collection component and an adsorption component. The collection component includes a rubber box and a steel wire box. The rubber box is installed below the discharge port to receive the small-diameter rubber particles output from the lower layer of the screening component. The steel wire box is located on one side of the rubber box, and a gap is left between the rubber box and the steel wire box. The fixed end of the adsorption component is installed in the gap between the rubber box and the steel wire box. Its adsorption end rotates to stay in the rubber box or the steel wire box, adsorbing the steel wire in the small-diameter rubber particles entering the rubber box and passively releasing the adsorbed steel wire in the steel wire box.

[0006] Preferably, the screening component includes a transport assembly, which includes a transport trough, a partition, a discharge component, and a baffle. The partition is installed in the middle of the transport trough, dividing it into upper and lower layers. The upper layer of the transport trough is used to transport primary rubber particles from its first end to its second end. The partition also has a number of screen holes of a predetermined size evenly distributed to screen the primary rubber particles, allowing particles with a diameter not larger than the predetermined size to leak into the lower layer. The discharge port is located on the lower side of the transport trough near the bottom. The discharge component is installed on the discharge port and is located on the outside of the transport trough to guide the screened small-diameter rubber particles from the discharge port into the rubber box. The baffle is installed on the lower layer of the transport trough, with its installation direction perpendicular to the transport direction of the small-diameter rubber particles. The two ends of the baffle are fixedly connected to the two side walls inside the transport trough and are located on the side of the discharge port near the second end of the transport trough to block the movement of the small-diameter rubber particles and allow them to move towards the discharge port.

[0007] Preferably, the screening component further includes at least two identical lifting assemblies, each lifting assembly including a lifting frame and two lifting ropes, with the two ends of the bottom of the lifting frame located on both sides of the transport trough; the first end of the two lifting ropes is connected to the top of the lifting frame, and the second end is connected to both sides of the top surface of the transport trough to lift the transport trough.

[0008] Preferably, the screening component further includes a vibration assembly, which includes a first drive motor, a drive disk, and a connecting rod. The fixed end of the first drive motor is close to the first end of the transport trough. The inner edge of the drive disk is fixedly installed on the drive end of the first drive motor to rotate under the drive of the first drive motor. The first end of the connecting rod is rotatably installed on the drive disk and located on the side of the drive disk facing away from the first drive motor. The second end is rotatably installed on the bottom surface of the first end of the transport trough to drive the transport trough to periodically swing along its length direction as the drive disk rotates.

[0009] Preferably, the adsorption assembly includes a fixed plate, a rotating shaft, and two adsorption rods. The fixed plate is fixedly installed in the gap between the rubber box and the wire box. The first end of the rotating shaft is fixedly installed on the fixed plate. The first ends of the two adsorption rods are rotatably installed on the second end of the rotating shaft. Each adsorption rod can rotate around the rotating shaft so that its second end extends into the rubber box or the wire box as it rotates. The second end of each adsorption rod is provided with a magnetic attraction element for adsorbing the wire in the rubber box.

[0010] Preferably, the wire box is located on the right side of the rubber box, and the right side wall of the rubber box and the left side wall of the wire box are both provided with first adsorption grooves. The bottom positions of the two first adsorption grooves correspond to the 0° and 180° positions of the rotating shaft, respectively, so that each adsorption rod can extend into the rubber box or the wire box from each first adsorption groove.

[0011] Preferably, the adsorption assembly includes a second drive motor, a connecting ring, a first conductive element, a second conductive element, and at least two magnetic attraction groups. The fixed end of the second drive motor is installed in the gap between the rubber box and the wire box. The connecting ring is sleeved on the drive end of the second drive motor. The first and second conductive elements are both installed along the circumference of the connecting ring on its outer edge. The first and second conductive elements are parallel to each other and are respectively carried by currents of opposite polarities. Each magnetic attraction group is evenly distributed circumferentially along the drive end of the second drive motor, and a gap is left between it and the connecting ring. Each component includes a magnetic rod, an electromagnet, a first brush, and a second brush. The first end of the magnetic rod is mounted on the drive end of a second drive motor, allowing the magnetic rod to rotate around its first end. The electromagnet is mounted on the second end of the magnetic rod. Both the first and second brushes are mounted on the magnetic rod, with their first ends electrically connected to the electromagnet. The second end of the first brush is connected to a first conductive element. The second brush contacts the second conductive element when the magnetic rod is inside the rubber box and moving towards the wire box, and separates from the second conductive element when the magnetic rod enters the wire box.

[0012] Preferably, the first conductive element is annular in shape; the second conductive element is arc-shaped and covers an area from 45° to 315° on the surface of the wiring ring, for separating the second brush from the second conductive element when the magnetic rod enters the wire box.

[0013] Preferably, the wire box is located on the right side of the rubber box, and the right side wall of the rubber box and the left side wall of the wire box are both provided with second adsorption grooves. The shapes of the two second adsorption grooves correspond to the shapes of the combination of the magnetic rod and the electromagnet, so that the magnetic rods of each magnetic group can alternately extend into the rubber box or the wire box through the second adsorption grooves.

[0014] Preferably, each of the second adsorption tanks has a soft baffle symmetrically provided on both sides of the opening, and the soft baffle can completely cover the opening of the second adsorption tank to prevent small-diameter rubber particles inside the rubber box or steel wires inside the steel wire box from leaking out of the opening of the second adsorption tank.

[0015] The aforementioned waste tire steel wire separation device includes a screening component and a separation component. The screening component consists of upper and lower layers. The upper layer transports primary rubber particles after magnetic separation, allowing particles with a diameter not exceeding a predetermined size to leak into the lower layer for screening. The lower layer of the screening component has a discharge port for conveying the small-diameter rubber particles obtained from screening to the separation component. The separation component includes a collection component and an adsorption component. The collection component includes a rubber box and a steel wire box. The rubber box is installed below the discharge port to receive the small-diameter rubber particles output from the lower layer of the screening component. The steel wire box is located on one side of the rubber box, with a gap between the rubber box and the steel wire box. The fixed end of the adsorption component is installed in the gap between the rubber box and the steel wire box, and its adsorption end rotates to adsorb the rubber particles. The primary rubber particles, after magnetic separation, are transported through a screening component. During transport, primary rubber particles with a particle size no larger than a predetermined size are allowed to fall to the lower layer, while the small-diameter rubber particles obtained from screening are sent to the rubber box. The adsorption end of the adsorption component then adsorbs the small-diameter rubber particles inside the rubber box, adsorbing the steel wires in the small-diameter rubber particles and periodically releasing the steel wires into the steel box. This reduces the amount of residual steel wires in the small-diameter rubber particles in the rubber box, thereby improving the purity of the finished rubber particles obtained after adsorption. This, in turn, improves the mechanical properties of recycled products such as reclaimed rubber and modified asphalt prepared from the finished rubber particles. Attached Figure Description

Detailed Implementation

[0025] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please refer to Figure 1This utility model provides a waste tire steel wire separation device 10, including a screening component 20 and a separation component 30. The screening component 20 is divided into upper and lower layers. The upper layer is used to transport primary rubber particles after magnetic separation, and during the transportation process, primary rubber particles with a particle size not larger than a predetermined size are allowed to leak to the lower layer for screening. The lower layer of the screening component 20 has a discharge port 215 for conveying the small-diameter rubber particles obtained by screening to the separation component 30. The separation component 30 includes a collection component 31 and an adsorption component 32. The collection component 31 includes a rubber box 311 and a steel wire box 312. The rubber box 311 is installed below the discharge port 215 to receive the small-diameter rubber particles output from the lower layer of the screening component 20. The steel wire box 312 is located on one side of the rubber box 311, and a gap is left between the rubber box 311 and the steel wire box 312. The fixed end of the adsorption component 32 is installed in the gap between the rubber box 311 and the steel wire box 312. In this process, the adsorption end rotates to remain in the rubber box 311 or the wire box 312, adsorbing the steel wires in the small-diameter rubber particles entering the rubber box 311 and passively releasing the adsorbed steel wires in the wire box 312. Thus, the primary rubber particles after magnetic separation are transported through the screening component 20. During transport, primary rubber particles with a diameter not larger than a predetermined size are allowed to fall to the lower layer, while the small-diameter rubber particles obtained from screening are sent to the rubber box 311. The adsorption end of the adsorption component 32 then adsorbs the small-diameter rubber particles inside the rubber box 311, adsorbing the steel wires in the small-diameter rubber particles and periodically releasing the adsorbed steel wires into the wire box 312. This reduces the amount of residual steel wires in the small-diameter rubber particles in the rubber box 311, thereby improving the purity of the finished rubber particles obtained after adsorption. This, in turn, improves the mechanical properties of recycled rubber and modified asphalt prepared from the finished rubber particles.

[0027] In this embodiment, the predetermined size is the size determined according to the process requirements of the downstream recycled products. For example, the size of rubber granules used for the production of recycled rubber is usually 1 to 4 mm; the size of rubber granules used for modified asphalt is usually 0.6 to 2 mm; primary rubber granules larger than the predetermined size are discharged from the second end of the screening member 20 and returned to the upstream crushing equipment for further crushing, so as to improve the overall raw material utilization rate and ensure that the specifications of small-diameter rubber granules meet the requirements of subsequent processing.

[0028] Please refer to Figure 1 and Figure 2Furthermore, the screening component 20 includes a transport assembly 21, which includes a transport trough 211, a partition 212, a discharge component 213, and a baffle 214. The partition 212 is installed in the middle of the transport trough 211, dividing the transport trough 211 into upper and lower layers. The upper layer of the transport trough 211 is used to transport primary rubber particles from its first end to its second end. The partition 212 is also evenly provided with a number of screen holes of a predetermined size to screen the primary rubber particles, so that primary rubber particles with a particle size not larger than the predetermined size fall to the lower layer. The lower side of the transport trough 211 has a discharge port 215 near the bottom surface. The discharge component 213 is installed on the discharge port 215 and is located on the outside of the transport trough 211 to guide the small-diameter rubber particles obtained by screening from the discharge port 215 into the rubber box. A baffle 214 is installed in the lower layer of the transport trough 211, with its installation direction perpendicular to the transport direction of the small-diameter rubber particles. The two ends of the baffle 214 are fixedly connected to the two side walls inside the transport trough 211, and are located on the side of the discharge port 215 near the second end of the transport trough 211, so as to block the movement of the small-diameter rubber particles and make them move towards the discharge port 215. Specifically, the baffle 214 blocks the movement of the lower layer of small-diameter rubber particles towards the second end of the transport trough 211 and guides them towards the discharge port 215, preventing the lower layer of small-diameter rubber particles from entering the next process from the second end of the transport trough 211. The discharge component 213 guides the small-diameter rubber particles into the rubber box 311, ensuring continuous output of small-diameter rubber particles and improving the efficiency of the separation process.

[0029] Please refer to Figure 1 Furthermore, the screening component 20 also includes at least two identical lifting assemblies 22. Each lifting assembly 22 includes a lifting frame 221 and two lifting ropes 222. The two ends of the bottom of the lifting frame 221 are located on both sides of the transport trough 211. The first end of the two lifting ropes 222 is connected to the top of the lifting frame 221, and the second end is connected to both sides of the top surface of the transport trough 211 to lift the transport trough 211. Specifically, the transport trough 211 is suspended in the air by the lifting frame 221 and the lifting ropes 222 so that the transport trough 211 can move back and forth.

[0030] Please refer to Figure 3Furthermore, the screening component 20 also includes a vibration assembly 23, which includes a first drive motor 231, a drive disk 232, and a connecting rod 233. The fixed end of the first drive motor 231 is close to the first end of the transport trough 211. The inner edge of the drive disk 232 is fixedly mounted on the drive end of the first drive motor 231 to rotate under the drive of the first drive motor 231. The first end of the connecting rod 233 is rotatably mounted on the drive disk 232 and located on the side of the drive disk 232 facing away from the first drive motor 231. The second end is rotatably mounted on the bottom surface of the first end of the transport trough 211 to move with the drive disk 232. The rotation causes the transport trough 211 to oscillate periodically along its length. Specifically, the drive disk 232 rotates under the drive of the first drive motor 231, causing the first end of the connecting rod 233 to rotate coaxially with the drive disk 232, which in turn causes the transport trough 211 connected to the second end of the connecting rod 233 to oscillate periodically along its length. During the oscillation, the rubber particles in the transport trough 211 vibrate, causing the rubber particles on the upper layer of the transport trough 211 to move from the first end to the second end of the transport trough 211. During the movement, primary rubber particles with a particle size not larger than a predetermined size fall into the lower layer, thereby screening the primary rubber particles.

[0031] Please refer to Figure 4 In one embodiment, the adsorption assembly 32 includes a fixing plate 321, a rotating shaft 322, and two adsorption rods 323. The fixing plate 321 is fixedly installed in the gap between the rubber box 311 and the wire box 312. The first end of the rotating shaft 322 is fixedly installed on the fixing plate 321. The first ends of the two adsorption rods 323 are rotatably installed on the second end of the rotating shaft 322. Each adsorption rod 323 can rotate around the rotating shaft 322 so that its second end extends into the rubber box 311 or the wire box 312 as the adsorption rod 323 rotates. The second end of each of the two adsorption rods 323 is provided with a magnetic suction element 324 for adsorbing the wire in the rubber box 311.

[0032] In this embodiment, the magnetic attractor 324 is a magnet or a permanent magnet to attract the steel wire.

[0033] Please refer to Figure 4In this embodiment, the wire box 312 is located to the right of the rubber box 311. Both the right side wall of the rubber box 311 and the left side wall of the wire box 312 have first adsorption grooves 313. The bottom positions of the two first adsorption grooves 313 correspond to the rotating shaft 322. The 0° and 180° positions are used to allow each adsorption rod 323 to extend from the first adsorption groove 313 into the rubber box 311 or the wire box 312. Specifically, the top of the circumference of the rotating shaft 322 is the 90° reference position, and the angle is increased clockwise. For ease of explanation, the two adsorption rods 323 are referred to as the first adsorption rod and the second adsorption rod, respectively. When the first adsorption rod is rotated into the wire box 312, it will be blocked and limited by the bottom of the first adsorption groove 313, keeping the first adsorption rod in a horizontal state. This ensures that the first adsorption rod adsorbs the steel wire in a stable horizontal posture. When a lot of broken steel wire is adsorbed on the first adsorption rod, the operator rotates the second adsorption rod into the rubber box 311 and then rotates the first adsorption rod into the wire box 312. The operator then cleans the steel wire adsorbed on the magnetic suction part 324 of the first adsorption rod, thereby achieving passive cleaning.

[0034] Please refer to Figures 5 to 7In one embodiment, the adsorption assembly 32 includes a second drive motor 325, a connecting ring 326, a first conductive element 327, a second conductive element 328, and at least one magnetic attraction group 329. The fixed end of the second drive motor 325 is installed in the gap between the rubber box 311 and the wire box 312. The connecting ring 326 is sleeved on the drive end of the second drive motor 325. The first conductive element 327 and the second conductive element 328 are both installed along the circumference of the connecting ring 326 on the outer edge of the connecting ring 326. The first conductive element 327 and the second conductive element 328 are parallel to each other and are respectively carried by currents of opposite polarities. Each magnetic attraction group 329 is installed along the second drive motor 325. The drive ends of the 25 are evenly distributed circumferentially, with gaps between them and the wiring ring 326. Each magnetic attraction group 329 includes a magnetic rod 3291, an electromagnet 3292, a first brush 3293, and a second brush 3294. The first end of the magnetic rod 3291 is mounted on the drive end of the second drive motor 325, so that the magnetic rod 3291 can rotate around its first end as the center by the second drive motor 325. The electromagnet 3292 is mounted on the second end of the magnetic rod 3291. The first brush 3293 and the second brush 3294 are both mounted on the magnetic rod 3291, and the first ends of the first brush 3293 and the second brush 3294 are electrically connected to the electromagnet 3292. The first brush 3293 is connected to the second conductive element 327 at its second end; the second brush 3294 is used to contact the second conductive element 328 when the magnetic rod 3291 is located in the rubber box 311 and moves towards the wire box 312, and to separate from the second conductive element 328 when the magnetic rod 3291 enters the wire box 312; specifically, the second drive motor 325 drives the magnetic rod 3291 to rotate; when the electromagnet 3292 enters the rubber box 311 with the rotation of the magnetic rod 3291, the first brush 3293 continues to contact the first conductive element 327, the second brush 3294 contacts the second conductive element 328, and the electromagnet 3292 and the first conductive element 327 are in contact. The second conductive element 327 and the second conductive element 328 form a closed circuit, which energizes the electromagnet 3292 and generates magnetism, thereby attracting the steel wire mixed in the small-diameter rubber particles in the rubber box 311. When the electromagnet 3292 continues to rotate into the steel wire box 312 with the magnetic suction rod 3291, the second brush 3294 disengages from the second conductive element 328, the connection between the electromagnet 3292 and the second conductive element 328 is broken, and the closed circuit between the electromagnet 3292 and the first conductive element 327 and the second conductive element 328 is broken, so that the electromagnet 3292 loses its magnetism and is de-energized, thereby passively releasing the attracted steel wire and ensuring that the attracted steel wire is transferred into the steel wire box 312.

[0035] Please refer to Figure 5 and Figure 8In this embodiment, the wire box 312 is located on the right side of the rubber box 311. Both the right side wall of the rubber box 311 and the left side wall of the wire box 312 have second adsorption grooves 314. The shapes of the two second adsorption grooves 314 correspond to the shape of the assembly composed of the magnetic rod and the electromagnet, so that the magnetic rods 3291 of each magnetic assembly 329 can alternately extend into the rubber box 311 or the wire box 312 through the second adsorption grooves 314. Specifically, the second drive motor 325 drives the magnetic rods 3291 to perform continuous unidirectional rotational motion, as follows: 1. The magnetic rod 3291 enters the rubber box 311 from the top of the second adsorption groove 314. The first brush 3293 continuously contacts the first conductive element 327, the second brush 3294 continuously contacts the second conductive element 328, and the electromagnet 3292 is energized and attracts the steel wire. 2. The magnetic rod 3291 leaves the rubber box 311 from the bottom of the second adsorption groove 314. The first brush 3293 continuously contacts the first conductive element 327, the second brush 3294 continuously contacts the second conductive element 328, and the electromagnet 3292 is energized and continuously attracts the steel wire. 3. The magnetic rod 3291 enters the wire box 312 from the bottom of the second adsorption groove 314. The first brush 3293 continuously contacts the first conductive element 327. The second brush 3294 separates from the second conductive element 328. The electromagnet 3292 is de-energized and releases the adsorbed wire. 4. Repeat the above process to continuously draw the steel wire in the rubber box 311 into the steel wire box 312, so as to improve the purity of the rubber particles in the rubber. In this embodiment, the first conductive element 327 is annular in shape; the second conductive element 328 is arc-shaped and covers the area from 45° to 315° on the surface of the connecting ring 326. It is used to separate the second brush 3294 from the second conductive element 328 when the magnetic rod 3291 enters the wire box 312. Specifically, by controlling the length of the second conductive element 328, the energizing time of the electromagnet 3292 is precisely controlled so that it is de-energized immediately upon entering the wire box 312, thereby separating the wire from the electromagnet 3292 and preventing the wire from being pulled back into the rubber box 311 when the electromagnet 3292 rotates to the rubber box 311.

[0036] Please refer to Figure 5 and Figure 8In this embodiment, each of the second adsorption tanks 314 has a soft baffle 315 symmetrically arranged on both sides of the opening, and the soft baffle 315 can completely cover the opening of the second adsorption tank 314 to prevent the rubber particles inside the rubber box 311 or the steel wire inside the steel wire box 312 from leaking out of the opening of the second adsorption tank 314. Specifically, since the soft baffle 315 is made of a soft material, such as rubber, the magnetic suction rod 3291 can still push open the soft baffle 315 and enter and exit the rubber box 311 or the steel wire box 312 during rotation.

[0037] Example 1: The waste tire steel wire separation device 10 adopts the working process of the first embodiment. For ease of description, in this embodiment, the two adsorption rods are referred to as the first adsorption rod and the second adsorption rod, respectively.

[0038] 1. The first drive motor 231 drives the transport trough 211 to oscillate periodically through the drive disc 232 and the connecting rod 233, causing the transport trough 211 to vibrate; 2. The primary rubber particles move to the second end of the transport tank 211 under the vibration. During this process, the sieve holes screen the primary rubber particles, and small-diameter rubber particles with a size not larger than the predetermined size fall into the lower layer of the transport tank 211. 3. As the transport trough 211 vibrates, small-diameter rubber particles fall into the rubber box 311 through the discharge port 215; 4. The operator rotates the first and second adsorption rods to position the first adsorption rod in the rubber box and the second adsorption rod in the wire box. The magnetic suction device installed on the first adsorption rod continuously adsorbs the wire in the small-diameter rubber particles. 5. When the number of steel wires adsorbed on the surface of the magnetic suction component of the first adsorption rod gradually increases and the adsorption capacity tends to be saturated, the operator first rotates the second adsorption rod into the rubber box, and then rotates the first adsorption rod into the steel wire box. The magnetic suction component installed on the second adsorption rod continues to adsorb the steel wires in the small-diameter rubber particles. 6. The operator removes the steel wires attracted by the magnetic attachment of the first adsorption rod into the steel wire box; 7. Repeat the above process, so that the first and second adsorption rods alternately enter the rubber box to adsorb the steel wire; 8. Periodically remove the finished rubber granules after adsorption from rubber box 311, and remove the collected steel wire from steel wire box 312. Example 2. Working process of the waste tire steel wire separation device 10 according to the second embodiment. 1. The first drive motor 231 drives the transport trough 211 to oscillate periodically through the drive disc 232 and the connecting rod 233, causing the transport trough 211 to vibrate; 2. The rubber granules move to the second end of the transport tank 211 under the vibration. During this process, the sieve holes screen the primary rubber granules, and the small-diameter rubber granules with a size not larger than the predetermined size fall into the lower layer of the transport tank 211. 3. As the transport trough 211 vibrates, small-diameter rubber particles fall into the rubber box 311 through the discharge port 215; 4. The magnetic rod 3291 rotates periodically under the drive of the second drive motor 325, and the electromagnet 3292 attracts the steel wire mixed in the small-diameter rubber particles. 5.
