Description

Technical Field

[0001] This utility model relates to the field of tire environmental protection treatment technology, specifically a large-scale waste tire crushing and steel wire separation device. Background Technology

[0002] With the rapid development of the automotive industry, the number of waste tires is increasing daily. How to efficiently and environmentally dispose of these waste tires has become an urgent problem. Large-scale waste tire crushing and steel wire separation devices have emerged, providing key technological support for the recycling of waste tires. These devices can effectively separate the rubber and steel wires from waste tires, achieving resource recycling and reducing environmental pollution. This device integrates crushing and steel wire separation functions. It can crush large waste tires, breaking them down into smaller blocks or granules. Simultaneously, the crushed tire material enters the steel wire separation stage. Using magnetic separation, the magnetic properties of the steel wires are utilized to attract the steel wires from the rubber material, facilitating subsequent reprocessing of both the rubber and steel wires.

[0003] For example, patent announcement number CN118438572B discloses an environmentally friendly waste tire rubber recycling device. After the steel wires and rubber of the waste tires are separated, they enter the conveyor belt of the second belt conveyor. The conveyor belt moves the steel wires and rubber of the waste tires to the outside of the steel wire processing box. At this time, the steel wires conveyed on the top surface of the second belt conveyor are attracted by magnetic blocks, so that the steel wires are attached to the bottom surface of the third belt conveyor. As the third belt conveyor rotates, the attracted steel wires move to the front end. When they move to the front end of the second belt conveyor, the attraction between the steel wires and the magnetic blocks decreases and disappears. At this time, the conveyor belt of the third belt conveyor separates from the steel wires. The steel wires are attracted and moved to the front end of the third belt conveyor and then separated, completing the magnetic separation operation of the waste tire steel wires.

[0004] In existing technologies for magnetic separation of steel wires, when there is a large amount of rubber material accumulated on the conveyor belt, the magnetic attraction force of the magnetic blocks on the steel wires decreases as the thickness of the rubber material accumulation increases. As a result, some steel wires are easily left behind and cannot be attracted, leading to poor separation effect. Utility Model Content

[0005] This utility model provides a large-scale waste tire crushing and steel wire separation device, which has the advantage of being able to attract steel wires pressed at the bottom of rubber particles upwards, so that the steel wires are at the top of the material pile, thereby improving the magnetic separation effect of the subsequent magnetic separation conveyor belt on the steel wires. This solves the problem that when there is a lot of rubber material piled up on the conveyor belt, the magnetic attraction force of the magnetic block on the steel wires will decrease as the thickness of the rubber material pile increases, which makes it easy for some steel wires to remain and not be attracted, resulting in poor separation effect.

[0006] To achieve the goal of attracting steel wires pressed against the bottom of rubber granules upwards and placing them at the top of the material pile, thereby improving the magnetic separation effect of the subsequent magnetic separation conveyor belt, this utility model provides the following technical solution: A large-scale waste tire crushing and steel wire separation device, including a support frame, a crusher mounted on the support frame, and further including: a conveyor belt mounted at the bottom outlet of the crusher, one end of which is inclined with a magnetic separation conveyor belt; a steel wire lifting mechanism mounted on the support frame, the steel wire lifting mechanism including a placement frame, a magnetic attraction component, and a drive component, the placement frame being mounted on the surface of the support frame, the magnetic attraction component and the drive component both being mounted on the surface of the placement frame, the magnetic attraction component being used to attract steel wires in the material pile to the top surface of the material pile, thereby facilitating the subsequent magnetic separation conveyor belt attraction, the drive component being used to drive the magnetic attraction component to reciprocate; and a vibration component mounted inside the conveyor belt, the vibration component being used to vibrate the material on the conveyor belt.

[0007] As a preferred embodiment of this utility model, the magnetic suction assembly includes a magnetic block, a partition, and a spring telescopic rod. The magnetic block is disposed on the surface of the driving assembly, the partition is disposed at the bottom of the magnetic block, one end of the spring telescopic rod is fixedly disposed on the surface of the partition, and the other end of the spring telescopic rod is fixedly disposed at the bottom of the placement rack.

[0008] As a preferred technical solution of this utility model, a magnetic strip is fixedly provided at the bottom of the magnetic block. The bottom end of the surface of the magnetic strip is set as arc. The surface of the partition is provided with a hole that matches the magnetic strip. The magnetic strip can pass through the partition through the hole.

[0009] As a preferred embodiment of this utility model, the driving assembly includes a drive motor, an eccentric wheel, a connecting rod, and a guide rod. The drive motor is mounted on one side of the placement frame via a mounting bracket. The eccentric wheel is disposed on the inner side wall of the placement frame. The output shaft of the drive motor passes through the placement frame and is fixedly connected to the eccentric wheel. The guide rod movably passes through the placement frame. The bottom end of the guide rod is fixedly disposed on the surface of the magnetic block. The bottom end of the connecting rod is connected to the top end of the guide rod via a connecting shaft. The top end of the connecting rod is connected to the eccentric shaft of the eccentric wheel.

[0010] As a preferred embodiment of this utility model, the vibration assembly includes a rotating rod and a protrusion. The rotating rod is disposed inside the conveyor belt via a fixed shaft, and the protrusion is integrally formed on the surface of the rotating rod. The rotating rod is connected to a drive motor via a transmission assembly.

[0011] As a preferred embodiment of this utility model, the transmission assembly includes a driving pulley, a driven pulley, and a transmission belt. The driving pulley is fixedly sleeved on the surface of the output shaft of the drive motor, and the driven pulley is fixedly sleeved on the surface of the rotating rod fixing shaft. The size of the driving pulley is larger than that of the driven pulley, and the two ends of the transmission belt are respectively sleeved on the surfaces of the driving pulley and the driven pulley.

[0012] As a preferred embodiment of this utility model, a connecting frame is fixedly provided on the surface of the conveyor belt, and multiple guide plates are mirror-arranged in a figure-eight shape on the surface of the connecting frame, and the connecting frame is set in an arc shape.

[0013] Compared with the prior art, this utility model provides a large-scale waste tire crushing and steel wire separation device, which has the following beneficial effects:

[0014] This large-scale waste tire shredding and steel wire separation device features a steel wire lifting mechanism. As the magnetic block moves downwards, it adheres to a partition, causing the partition to move downwards as well. Simultaneously, the partition extends a spring-loaded telescopic rod, bringing the magnetic block closer to the material. The magnetic block attracts the steel wires pressed against the bottom of the rubber granules, causing them to adhere to the surface of the partition. A guide rod then moves upwards, driving the magnetic block upwards. Simultaneously, the spring-loaded telescopic rod elastically resets, causing the partition to move upwards along with the magnetic block. When the magnetic block detaches from the partition, it loses its magnetic attraction to the steel wires, causing them to fall downwards and onto the top layer of the material. This achieves the advantage of attracting steel wires pressed against the bottom of the rubber granules upwards, placing them at the top of the material pile. This results in better magnetic separation of the steel wires by the subsequent magnetic conveyor belt. This addresses the problem that when there is a large accumulation of rubber on the conveyor belt, the magnetic attraction of the magnetic block to the steel wires decreases with the thickness of the rubber accumulation, leaving some steel wires that are difficult to attract, leading to poor separation results.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model discloses a large-scale waste tire crushing and steel wire separation device, including a support frame 1, a crusher 2 mounted on the support frame 1, and a conveyor belt 3 mounted at the bottom outlet of the crusher 2, with a magnetic separation conveyor belt 4 inclined at one end of the conveyor belt 3; a steel wire lifting mechanism mounted on the support frame 1, the steel wire lifting mechanism including a placement frame 5, a magnetic attraction component, and a drive component, the placement frame 5 being mounted on the surface of the support frame 1, the magnetic attraction component and the drive component being mounted on the surface of the placement frame 5, the magnetic attraction component being used to attract the steel wire in the material pile to the top surface of the material pile, thereby facilitating the subsequent attraction by the magnetic separation conveyor belt 4, the drive component being used to drive the magnetic attraction component to reciprocate; and a vibration component mounted inside the conveyor belt 3, the vibration component being used to vibrate the material on the conveyor belt 3.

[0023] Specifically, the magnetic suction assembly includes a magnetic block 6, a partition 7, and a spring telescopic rod 8. The magnetic block 6 is disposed on the surface of the drive assembly, the partition 7 is disposed at the bottom of the magnetic block 6, one end of the spring telescopic rod 8 is fixedly disposed on the surface of the partition 7, and the other end of the spring telescopic rod 8 is fixedly disposed at the bottom of the placement rack 5.

[0024] In this embodiment, when the guide rod 13 moves downward, it will drive the magnetic block 6 to move downward, bringing the magnetic block 6 closer to the conveyor belt 3. During the downward movement, the magnetic block 6 will come into contact with the partition 7 and drive the partition 7 to move downward together. At the same time, the partition 7 will drive the spring telescopic rod 8 to extend elastically, thereby bringing the magnetic block 6 closer to the material. The magnetic block 6 can attract the steel wire pressed at the bottom of the rubber particles upward, so that the steel wire is attracted to the surface of the partition 7. Then, the guide rod 13 moves upward, driving the magnetic block 6 to move upward. At the same time, under the elastic reset of the spring telescopic rod 8, the partition 7 will move upward together with the magnetic block 6. When the magnetic block 6 separates from the partition 7, it loses its magnetic attraction to the steel wire, causing the steel wire to detach from the partition 7 and fall downward. Thus, the steel wire will fall to the top layer of the material, making the subsequent magnetic separation conveyor belt 4 perform better on the steel wire magnetic separation.

[0025] Specifically, a magnetic strip 9 is fixedly installed at the bottom of the magnetic block 6. The bottom end of the surface of the magnetic strip 9 is arc-shaped. The surface of the partition 7 is provided with a hole that matches the magnetic strip 9. The magnetic strip 9 can pass through the partition 7 through the hole.

[0026] In this embodiment, the magnetic block 6 moves downward and comes into contact with the partition 7, causing the partition 7 to move downward as well. At the same time, the magnetic strip 9 on the surface of the magnetic block 6 passes through the insertion hole and penetrates the partition 7. The magnetic strip 9 can be inserted into the material pile, thereby improving the adsorption effect.

[0027] Specifically, the drive assembly includes a drive motor 10, an eccentric wheel 11, a connecting rod 12, and a guide rod 13. The drive motor 10 is mounted on one side of the placement frame 5 via a mounting bracket. The eccentric wheel 11 is located on the inner side wall of the placement frame 5. The output shaft of the drive motor 10 passes through the placement frame 5 and is fixedly connected to the eccentric wheel 11. The guide rod 13 movably passes through the placement frame 5. The bottom end of the guide rod 13 is fixedly located on the surface of the magnetic block 6. The bottom end of the connecting rod 12 is connected to the top end of the guide rod 13 via a connecting shaft. The top end of the connecting rod 12 is connected to the eccentric shaft of the eccentric wheel 11.

[0028] In this embodiment, the drive motor 10 is started by a switch. The output shaft of the drive motor 10 drives the eccentric wheel 11 to rotate. The eccentric wheel 11 drives the connecting rod 12 to rotate and swing around the eccentric wheel 11. At the same time, the connecting rod 12 drives the guide rod 13 to move up and down. The guide rod 13 drives the magnetic block 6 to move, thereby facilitating the up and down reciprocating motion of the magnetic block 6.

[0029] Specifically, the vibration assembly includes a rotating rod 14 and a protrusion 15. The rotating rod 14 is disposed inside the conveyor belt 3 via a fixed shaft, and the protrusion 15 is integrally formed on the surface of the rotating rod 14. The rotating rod 14 is connected to the drive motor 10 via a transmission assembly. The transmission assembly includes a drive pulley 16, a driven pulley 17, and a transmission belt 18. The drive pulley 16 is fixedly sleeved on the surface of the output shaft of the drive motor 10, and the driven pulley 17 is fixedly sleeved on the surface of the fixed shaft of the rotating rod 14. The size of the drive pulley 16 is larger than that of the driven pulley 17. The two ends of the transmission belt 18 are respectively sleeved on the surfaces of the drive pulley 16 and the driven pulley 17.

[0030] In this embodiment, when the output shaft of the drive motor 10 rotates, it will simultaneously drive the active pulley 16 to rotate. The active pulley 16 drives the driven pulley 17 to rotate via the transmission belt 18. The driven pulley 17 drives the rotating rod 14 to rotate. Through the transmission assembly, the power of the drive assembly can be used to drive the rotating rod 14 to rotate. Then, the protrusions 15 on the surface of the rotating rod 14 continuously squeeze the conveyor belt 3, causing the material on the surface of the conveyor belt 3 to vibrate, thereby making it easier for the magnetic block 6 to attract the steel wire pressed at the bottom of the rubber particles.

[0031] Specifically, a connecting frame 19 is fixedly installed on the surface of the conveyor belt 3. Multiple guide plates 20 are mirrored on the surface of the connecting frame 19 in a figure-eight shape, and the connecting frame 19 is set in an arc shape.

[0032] In this embodiment, when the conveyor belt 3 conveys materials, the guide plate 20 can guide the materials to disperse them evenly and reduce the thickness of material accumulation. By setting the connecting frame 19 to an arc shape, the strength of the connecting frame 19 can be improved, making it less prone to breakage.

[0033] The working principle and usage process of this utility model are as follows: During use, the initially crushed tire rubber blocks are fed into the crusher 2 for further crushing into rubber particles, thereby separating the steel wire. The crushed material, after reaching the required size, falls through the filter screen at the outlet of the crusher 2 onto the surface of the conveyor belt 3. The conveyor belt 3 transports the rubber particles and steel wire. When there is a large output, the material accumulates, and some of the steel wire is pressed against the bottom of the rubber particles. The drive motor 10 is started by a switch. The output shaft of the drive motor 10 drives the eccentric wheel 11 to rotate. The eccentric wheel 11 drives the connecting rod 12 to rotate and swing around the eccentric wheel 11. Simultaneously, the connecting rod 12 drives the guide rod 13 to move up and down reciprocally. When the guide rod 13 moves downward, it drives the magnetic block 6 to move downward, bringing the magnetic block 6 close to the conveyor belt 3. During the downward movement, the magnetic block 6 comes into contact with the partition 7, causing the partition 7 to move downward as well. Simultaneously, the partition 7 causes the spring to extend and retract. The rod 8 extends elastically, allowing the magnetic block 6 to approach the material. The magnetic block 6 can attract the steel wire pressed against the bottom of the rubber granules upwards, causing the steel wire to adhere to the surface of the partition 7. Then, the guide rod 13 moves upwards, driving the magnetic block 6 upwards. Simultaneously, under the elastic reset of the spring telescopic rod 8, the partition 7 moves upwards along with the magnetic block 6. When the magnetic block 6 detaches from the partition 7, it loses its magnetic attraction to the steel wire, causing the steel wire to detach from the partition 7 and fall downwards, thus falling to the top layer of the material. As the output shaft of the drive motor 10 rotates, it simultaneously drives the drive pulley 16 to rotate. The drive pulley 16 drives the driven pulley 17 to rotate via the transmission belt 18. The driven pulley 17 drives the rotating rod 14 to rotate. Then, the protrusions 15 on the surface of the rotating rod 14 continuously squeeze the conveyor belt 3, causing the material on the surface of the conveyor belt 3 to vibrate, thus making it easier for the magnetic block 6 to attract the steel wire pressed against the bottom of the rubber granules.

[0034] Afterwards, conveyor belt 3 continues to transport the material. When it passes through magnetic separation conveyor belt 4, magnetic separation conveyor belt 4 will adsorb the steel wires in the material to its surface, thereby achieving the screening of steel wires and rubber particles. After the steel wires pressed at the bottom of the rubber particles are screened to the top layer of the rubber particles, the magnetic separation conveyor belt 4 can more comprehensively adsorb the steel wires, improving the steel wire separation effect. Then, magnetic separation conveyor belt 4 will transport and collect the steel wires, while conveyor belt 3 will transport and collect the remaining rubber particles.
