Description

Technical Field

[0001] The invention relates to the technical field of tire processing, in particular to an environmentally friendly processing device for recycling waste tire rubber. Background Art

[0002] With the rapid development of the automobile industry, the number of waste tires has increased year by year, which has brought great pressure to the environment. Rubber is a valuable resource. The rubber in waste tires has a high recycling value. Through certain technical means, the rubber in waste tires can be recycled and converted into new rubber products, thereby realizing the recycling of resources. This can not only alleviate the shortage of rubber resources, but also reduce production costs and improve economic benefits.

[0003] After searching, a Chinese patent with the announcement number CN215472420U provides an environmentally friendly treatment device for recycling and utilizing waste tires, including a crushing box, a chassis is fixedly arranged on one side of the crushing box, a motor is fixedly arranged inside the chassis, a rotating shaft is fixedly connected to the output shaft of the motor, a main gear is fixedly arranged on the surface of the rotating shaft, a slave gear is movably arranged on one side of the main gear, a second rotating shaft is fixedly arranged on the inner wall of the slave gear, a crushing roller is fixedly arranged on one end of the rotating shaft and the second rotating shaft, a collecting hopper is arranged directly below the crushing roller, a supporting plate is fixedly arranged on the bottom of the crushing box, and a movable rod, a connecting rod and a rocking rod are arranged, and the rotating rocking rod drives the movable plate at one end of the movable rod and the screening plate to move horizontally repeatedly through the connecting rod, so that the screening plate vibrates, and the vibration is used to increase the screening speed and improve the processing efficiency;

[0004] However, it was found during use that there were steel wires inside the waste tires. The device failed to effectively remove the steel wires when processing the waste tires, which resulted in a large amount of steel wires remaining in the recycled rubber, which not only affected the quality of the rubber, but also caused inconvenience to subsequent processing and use. Due to the poor effect of removing the steel wires, the device may be disturbed by the residual steel wires when screening and recycling the rubber, reducing the processing efficiency. This not only prolongs the processing cycle of waste tires, but also increases the processing cost. During the processing, if the steel wires and rubber are not effectively separated, it is easy for some of the steel wires to enter the subsequent recycling process, posing a potential threat to the environment and the quality of the recycled rubber, and is not conducive to the environmentally friendly treatment of the recycling of waste tire rubber. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides an environmentally friendly treatment device for recycling waste tire rubber, which solves the problem that the waste tire contains steel wires.

Due to the poor effect of removing the steel wires, the device may be disturbed by the residual steel wires when screening and recycling the rubber, which reduces the treatment efficiency. This not only prolongs the treatment cycle of the waste tires, but also increases the treatment cost. During the treatment process, if the steel wires and rubber are not effectively separated, it is easy to cause part of the steel wires to enter the subsequent recycling link, which poses a potential threat to the environment and the quality of the recycled rubber, and is not conducive to the technical problem of environmentally friendly treatment of the recycling of waste tire rubber.

[0022] Through the above technical scheme, the steel wire transported on the top surface of the conveyor belt of the second belt conveyor is adsorbed by the magnetic suction block, so that the steel wire is attached to the bottom surface of the conveyor belt of the third belt conveyor. Through the rotation of the third belt conveyor, the adsorbed steel wire moves to the front end, and the suction force between the steel wire and the magnetic suction block is reduced and disappears. At this time, the conveyor belt of the third belt conveyor is separated from the steel wire.

[0023] Beneficial effects of the present invention:

[0024] 1. In the present invention, the waste tire is transported to the feed hopper through an external device and then falls into the crushing box. Then, the output shaft of the first motor drives one of the crushing rollers and one of the first gears to rotate, so that one of the first gears is meshed and transmitted to the other first gear to rotate, so that the two crushing rollers rotate in opposite directions, and the waste tire is torn and crushed, ensuring that the tire is fully crushed, improving the crushing effect, and providing convenience for subsequent processing work. The crushed waste tire falls into the first groove block and the top surface of the first guide block, and slides and falls on the conveyor belt at one end of the first belt conveyor at the left end of the first guide block. The crushed waste tire rubber fragments are transported to Inside the screening box, screening is carried out through the disc screen assembly. The screened waste tire rubber fragments fall into the top surface of the second guide block and slide to the inside of the wire processing box for wire separation processing through the wire separation assembly, which is convenient for crushing and separating the wire and rubber in the waste tire, ensuring the efficient separation of the wire and rubber. The waste rubber tire fragments that fail to pass the screening are moved to the second groove block through the disc screen assembly and then enter the reflux block, slide along the reflux block and enter the crushing box for secondary crushing until the screening requirements are met, thereby improving the processing efficiency and crushing effect of waste rubber tires, improving the quality of recycled rubber, and providing strong technical support for the recycling and utilization of waste tires.

[0025] 2. In the present invention, one of the disc rollers is driven to rotate synchronously by the output shaft of the second motor, so that one of the second gears drives the adjacent second gear to rotate synchronously through the meshing transmission of the chain, so that multiple chains rotate synchronously, multiple second gears rotate synchronously, and multiple disc rollers rotate in the same direction, so that waste tire rubber fragments of appropriate size penetrate the gap between two adjacent disc rollers and fall into the top surface of the second guide block below, and the waste tire rubber fragments that fail to penetrate the gap between the two adjacent disc rollers gradually move along the upper end of the disc roller to the direction of the second groove block, and are conveniently moved to the reflux block to flow back to the crushing box for further crushing treatment, thereby ensuring the high efficiency and accuracy of screening, improving screening efficiency, avoiding the jamming and damage of waste tire rubber fragments during the screening process, ensuring the smoothness of the flow of waste tire rubber fragments, and reducing the equipment failure rate and maintenance cost.

[0026] 3. In the present invention, after being crushed and screened, the waste tire enters the steel wire processing box. At this time, the separation roller is driven by the output shaft of the third motor to rotate along the steel wire processing box, and the separation roller drives multiple first separation knives to rotate, so that the first separation knife and the second separation knife crush the waste tire fragments again, and part of the waste tire fragments fall into the arc screen through the gap between the separation roller and the second separation knife. At this time, the rotating first separation knife pushes the waste tire fragments in the arc screen to be squeezed and cut and crushed by the second separation knife. After continuous cutting and crushing to a suitable size, the sieve holes of the arc screen pass through the sieve holes and fall into the top surface of the third groove block below and the top surface of the conveyor belt at the right end of the second belt conveyor. The triangular leakage-proof block reduces the leakage of waste tires after steel wire separation, facilitates the crushing and separation of steel wire and rubber in waste tires, ensures the efficient separation of steel wire and rubber, improves the quality and purity of recycled rubber, and the steel wire in the waste tire can be separated more thoroughly, reduces the amount of steel wire remaining in the rubber, avoids the steel wire from entering the subsequent recycling link, and reduces the impact on the environment and the quality of recycled rubber.

[0027] 4. In the present invention, the triangular blocks are used to block the falling waste tire fragments during use, thereby reducing the impact of the waste tire fragments on the hexagon socket bolts installed on the second separation knife during crushing, and improving the wire separation effect. When replacing the first separation knife and the second separation knife damaged during use, the buckle locking piece is separated from the buckle fixing piece, and the cover plate is rotated open along the wire processing box, and the hexagon socket bolts on the first separation knife and the second separation knife that need to be replaced are taken out, and the new first separation knife and the second separation knife are reinstalled and fixed by the hexagon socket bolts, which makes maintenance and replacement more convenient. Multiple separate first separation knives and second separation knives reduce the cost of maintenance and replacement, making the entire maintenance process more time-saving and labor-saving, and providing reliable guarantee for the recycling and utilization of waste tires.

[0028] 5. In the present invention, after the steel wire and rubber of the waste tire are separated, they enter the conveyor belt of the second belt conveyor, and the steel wire and rubber of the waste tire are moved to the outside of the steel wire processing box through the conveyor belt. At this time, the steel wire transported on the top surface of the conveyor belt of the second belt conveyor is adsorbed by the magnetic suction block, so that the steel wire is attached to the bottom surface of the conveyor belt of the third belt conveyor. Through the rotation of the third belt conveyor, the adsorbed steel wire moves to the front end. When it moves to the front end of the second belt conveyor, the suction force between the steel wire and the magnetic suction block decreases and disappears. At this time, the conveyor belt of the third belt conveyor is separated from the steel wire, and the steel wire is adsorbed and moved to the front end of the conveyor belt of the third belt conveyor and then separated, completing the magnetic separation operation of the steel wire of the waste tire, improving the separation efficiency and magnetic separation effect of the steel wire in the waste tire, and improving the efficiency and capacity of the entire processing flow. At the same time, due to the characteristics of the magnetic force, the adsorption process causes less damage to the steel wire, ensuring the recovery quality of the steel wire, and the steel wire content in the rubber fragments after magnetic separation is significantly reduced, reducing the difficulty and cost of subsequent processing links, and improving the efficiency and economic benefits of the entire processing flow.

A triangular leak-proof block 912 is slidably connected to the top surface of the right end of the second belt conveyor 10, and the outer wall of the triangular leak-proof block 912 is fixedly connected to the inner wall of the wire processing box 8; after continuous cutting and crushing to a suitable size, the sieve holes of the arc-shaped screen 908 pass through the top surface of the third groove block 910 below and the top surface of the conveyor belt at the right end of the second belt conveyor 10, and the triangular leak-proof block 912 reduces the leakage of waste tires after wire separation, so as to facilitate the crushing and separation of steel wire and rubber in waste tires.

[0052] During wire separation, the waste tire enters the wire processing box 8 after being crushed and screened. At this time, the separation roller 901 is driven by the output shaft of the third motor 909 to rotate along the wire processing box 8, and the separation roller 901 drives multiple first separation knives 903 to rotate, so that the first separation knives 903 and the second separation knives 905 crush the waste tire fragments again, and some of the waste tire fragments fall into the arc screen 908 through the gap between the separation roller 901 and the second separation knife 905. At this time, the rotating first separation knife 903 pushes the waste tire fragments inside the arc screen 908 to be squeezed and cut by the second separation knife 905. The waste tires are crushed and continuously cut and crushed to a suitable size, and then pass through the sieve holes of the arc screen 908 and fall into the top surface of the third groove block 910 below and the top surface of the conveyor belt at the right end of the second belt conveyor 10. The triangular leak-proof block 912 reduces the leakage of waste tires after wire separation, and facilitates the crushing and separation of steel wire and rubber in waste tires, ensuring the efficient separation of steel wire and rubber, improving the quality and purity of recycled rubber, and allowing the steel wire in waste tires to be separated more thoroughly, reducing the amount of residual steel wire in rubber, avoiding the steel wire from entering the subsequent recycling process, and reducing the impact on the environment and the quality of recycled rubber.

[0053] During use, the triangular block 911 is used to block the falling waste tire fragments, thereby reducing the impact of the waste tire fragments on the hexagon socket bolts 907 installed on the second separation knife 905 when they are crushed, and improving the wire separation effect. When replacing the first separation knife 903 and the second separation knife 905 damaged during use, the buckle locking piece 15 is separated from the buckle fixing piece 18, and the cover plate 17 is rotated and opened along the wire processing box 8, and the hexagon socket bolts 907 on the first separation knife 903 and the second separation knife 905 that need to be replaced are taken out, and the new first separation knife 903 and the second separation knife 905 are reinstalled and fixed by the hexagon socket bolts 907, so that maintenance and replacement are more convenient. Multiple separate first separation knives 903 and second separation knives 905 reduce the cost of maintenance and replacement, making the entire maintenance process more time-saving and labor-saving, and providing reliable guarantee for the recycling and utilization of waste tires. Embodiment 4

[0054] like Figure 1 , Figure 2 , Figure 6 and Fig.11 As shown, this embodiment is based on the previous embodiment, and is different from the previous embodiment in that the magnetic separation component 11 includes a third belt conveyor 1101, and a magnetic suction block 1102 is arranged inside the third belt conveyor 1101. The magnetic suction block 1102 is installed on the outer wall of the wire processing box 8 through a mounting seat, and a plurality of partitions 1103 are fixedly arranged on the outer wall of the conveyor belt of the third belt conveyor 1101 in a uniformly arranged structure. The outer wall of the partition 1103 is in clearance with the top surface of the second belt conveyor 10, and the right wall of the third belt conveyor 1101 The third belt conveyor 1101 is fixedly connected to the outer wall of the steel wire processing box 8, and its front end extends to the front end of the second belt conveyor 10; the steel wire transported on the top surface of the conveyor belt of the second belt conveyor 10 is adsorbed by the magnetic block 1102, so that the steel wire is attached to the bottom surface of the conveyor belt of the third belt conveyor 1101; the third belt conveyor 1101 is rotated to move the adsorbed steel wire toward the front end, and the suction force between the steel wire and the magnetic block 1102 is reduced and disappears, at which time the conveyor belt of the third belt conveyor 1101 is separated from the steel wire.

[0055] During magnetic separation, the steel wire and rubber of the waste tire are separated and enter the conveyor belt of the second belt conveyor 10. The steel wire and rubber of the waste tire are moved to the outside of the steel wire processing box 8 through the conveyor belt. At this time, the steel wire transported on the top surface of the conveyor belt of the second belt conveyor 10 is adsorbed by the magnetic suction block 1102, so that the steel wire is attached to the bottom surface of the conveyor belt of the third belt conveyor 1101. The adsorbed steel wire is moved to the front end through the rotation of the third belt conveyor 1101. When it moves to the front end of the second belt conveyor 10, the suction force between the steel wire and the magnetic suction block 1102 is reduced and disappears. At the same time, the conveyor belt of the third belt conveyor 1101 is separated from the steel wire, and the steel wire is adsorbed and moved to the front end of the conveyor belt of the third belt conveyor 1101 and then separated, completing the magnetic separation operation of the steel wire in the waste tire, thereby improving the separation efficiency and magnetic separation effect of the steel wire in the waste tire, and improving the efficiency and capacity of the entire processing flow. At the same time, due to the characteristics of the magnetic force, the adsorption process causes less damage to the steel wire, thereby ensuring the recovery quality of the steel wire. The steel wire content in the rubber fragments after magnetic separation is significantly reduced, thereby reducing the difficulty and cost of subsequent processing links, and improving the efficiency and economic benefits of the entire processing flow.
