Description

Technical Field

[0001] The present invention relates to the technical field of reclaimed rubber production, and particularly relates to a magnetic separation device for continuous production of reclaimed rubber. Background Art

[0002] Reclaimed rubber is rubber processed from vulcanized scrap and waste in rubber product production, with a certain plasticity and can be reused. Reclaimed rubber can partially replace raw rubber in rubber products. The production process of reclaimed rubber mainly includes three processes: crushing, regeneration (desulfurization), and refining. When waste rubber products are crushed, metal objects such as steel wires inside will also be broken and incorporated into the crushed rubber material. Therefore, a magnetic separation device is needed to separate the metal wires from the rubber powder.

[0003] There are various types of magnetic separation devices in the prior art, such as belt magnetic separators, drum magnetic separators, and roll magnetic separators. They mainly adsorb metal impurities in the rubber powder by permanent magnets when the rubber powder moves, so as to achieve the purpose of magnetic separation. There are relatively many metal impurities in reclaimed rubber powder, and it cannot be separated by magnetic separation only once. Therefore, multiple magnetic separation operations are required to separate the metal wires to make the rubber material meet the requirements. In the belt magnetic separator, since the permanent magnet is located above the conveyor belt, when separating the metal wires on the permanent magnet, the metal wires will fall again, affecting the magnetic separation quality; the multi-stage roll magnetic separator can achieve multi-stage magnetic separation of reclaimed rubber material through the setting of roll magnets in multiple stages, but the roll magnets are arranged closely, which is prone to magnetic agglomeration or magnetic inclusion phenomena; in addition, after multiple magnetic separations, the metal wires that have not been screened will have rubber particles wrapped on their surfaces, making them difficult to be adsorbed, affecting the final quality of the material. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of unreasonable arrangement of multi-stage magnetic separation devices in the prior art, so as to provide a magnetic separation device for continuous production of reclaimed rubber.

[0005] The above technical object of the present invention is achieved by the following technical solutions:

[0006] A magnetic separation device for continuous production of recycled rubber, comprising a batching device, a plurality of production devices and a post-treatment device arranged in sequence along the production process. The batching device includes a feeding member, a plurality of large bins arranged in parallel and a plurality of batching bins arranged in parallel. The feeding member is connected to the large bins through a feeding conveyor belt. The plurality of batching bins are connected to the production devices through batching conveyor members. The number of the production devices is correspondingly set with the number of the batching bins. Each production device includes a crushing device, a return material device and a magnetic separation device. The feeding end of the crushing device is connected to the batching conveyor member. The return material device and the magnetic separation device are both arranged beside the crushing device. The magnetic separation device includes a first magnetic separation member, a second magnetic separation member, a third magnetic separation member and a fourth magnetic separation member. The second magnetic separation member is installed above the first magnetic separation member close to the third magnetic separation member. The third magnetic separation member and the first magnetic separation member are oppositely arranged above the top of the fourth magnetic separation member. The bottom discharge end of the fourth magnetic separation member is connected to the post-treatment device. The post-treatment device includes a material transporting device and a screening device. The material transporting device is connected to the discharge end of the magnetic separation device. The screening device is arranged at the end of the material transporting device.

[0007] By adopting the above technical solution, the raw materials are fed through the feeding member and stored in the large bins. During the production process, the feeding is adjusted through the large bins and the batching bins and sent to the crushing device for crushing production. The rubber materials in the crushing process are sent to the magnetic separation device for multi-stage magnetic separation operation only after being screened and qualified. The unqualified particles are sent back for crushing operation through the return material device to ensure the quality of the rubber materials. The multi-stage magnetic separation members arranged in a staggered manner and of different types can effectively remove the metal impurities in the rubber materials, avoid affecting the quality of the rubber materials, and collect the removed metal impurities for easy recycling of the materials.

[0008] Further, the feeding member includes a plurality of cutting machines and a direct feeding bin. The discharge ends of the plurality of cutting machines are connected to the same horizontal cutting conveyor belt. The conveying end of the cutting conveyor belt is arranged above the feeding conveyor belt and the conveying direction of the cutting conveyor belt is perpendicular to the conveying direction of the feeding conveyor belt. One end of the feeding conveyor belt extends to the bottom of the direct feeding bin and the other end extends to the top of a large bin. The height of the feeding conveyor belt near the feeding bin is lower than the height of the end near the large bin. Storage conveyor belts are arranged on the tops of adjacent large bins and are arranged in a vertical stagger between adjacent storage conveyor belts. The conveying end of the feeding conveyor belt extends above the storage conveyor belt. The height of the storage conveyor belt on the side close to the feeding conveyor belt is higher than the height of the storage conveyor belt on the side far from the feeding conveyor belt. The plurality of large bins are all connected to the batching bins through bin transporting members. The batching bins supply materials to the crushing device through batching conveyor members.

[0009] By adopting the above technical solution, different feeding components are selected for feeding according to the types of raw materials. For raw materials such as waste tires, cut blocks are selected for cutting and conveying for feeding, and the already cut and formed rubber blocks are fed and conveyed through a direct feeding bin. After the raw materials are supplied, they are stored in a large bin. According to the workload, the corresponding number of large bins are stored, and when needed, they are fed to the crushing device through the bin transportation component and the batching conveying component.

[0010] Furthermore, the crushing device includes a crushing frame, multiple pairs of crushing rollers arranged in pairs, a crushing driving member, and a vibrating blanking belt. A crushing inlet is provided at the top of the crushing frame, and a crushing outlet is opened on one side at the bottom. Both ends of each pair of crushing rollers are rotatably positioned and installed on the crushing frame, and a pair of crushing rollers in the same group rotate relatively. The axes of the crushing rollers are all arranged along the length direction of the crushing frame. The crushing driving member is installed on the crushing frame and is arranged at one end of the crushing rollers to drive multiple groups of crushing rollers to rotate. The vibrating blanking belt extends out from the bottom of the crushing frame, and the length direction of the vibrating blanking belt is perpendicular to the axis direction of the crushing rollers. A return material outlet is provided at one end of the vibrating blanking belt away from the crushing frame, and a screening outlet is provided on the side of the vibrating blanking belt away from the crushing frame.

[0011] By adopting the above technical solution, the distributed raw materials fall into the crushing frame and are crushed by multiple groups of crushing rollers. The crushed rubber material falls on the vibrating blanking belt. The vibrating blanking belt selects a screen with a suitable aperture for vibrating screening and blanking. The rubber material that meets the requirements is discharged through the screening outlet and enters the magnetic separation device for subsequent magnetic separation, while the rubber material that does not meet the diameter requirements is returned through the return material outlet and undergoes a further return material crushing operation through the return material device.

[0012] Furthermore, a magnetic separation conveyor belt is provided on one side of the vibrating blanking belt away from the batching conveying component. The magnetic separation conveyor belt is arranged along the length direction of the vibrating blanking belt. The feeding end of the magnetic separation conveyor belt is close to the screening outlet, and the discharging end of the magnetic separation conveyor belt is close to the crushing device. The magnetic separation conveyor belt is of an inclined structure, and the height of the feeding end of the magnetic separation conveyor belt is lower than the height of the discharging end of the magnetic separation conveyor belt. A U-shaped baffle is also provided at the feeding end of the magnetic separation conveyor belt. The baffle is perpendicular to the upper surface of the magnetic separation conveyor belt. A first magnetic separation component and a second magnetic separation component are provided above the magnetic separation conveyor belt near the discharging end.

[0013] By adopting the above technical solution, the rubber material that meets the requirements is screened and then conveyed by the magnetic separation conveyor belt into multiple magnetic separation components for magnetic separation operations. The magnetic separation conveyor belt is inclined and a baffle is provided at the end to prevent the rubber material from falling on the ground. The magnetic separation conveyor belt conveys the rubber material through the magnetic separation operations of the first magnetic separation component and the second magnetic separation component.

[0014] Further, the first magnetic separation member is installed in parallel on the magnetic separation conveyor belt. The first magnetic separation member includes a first magnetic separation frame and a first magnetic separation roller set. Both ends of the first magnetic separation roller set are rotationally installed on the first magnetic separation frame in a positioned manner, and the axial direction thereof is perpendicular to the conveying direction of the magnetic separation conveyor belt. The first magnetic separation roller set includes a first magnetic separation roller, a second magnetic separation roller, a third magnetic separation roller, and a fourth magnetic separation roller arranged in sequence along the conveying direction of the magnetic separation conveyor belt. Arc-shaped first magnetic blocks are installed near the bottom inside the first magnetic separation roller, the second magnetic separation roller, the third magnetic separation roller, and the fourth magnetic separation roller. Transfer ports are formed in the top of the first magnetic separation frame corresponding to the third magnetic separation roller and the fourth magnetic separation roller. The transfer ports are arranged along the length direction of the magnetic separation frame, and a second magnetic separation member is arranged in parallel above the transfer ports.

[0015] By adopting the above technical solution, the first magnetic separation roller set includes four magnetic separation rollers. The multi-roller arrangement increases the magnetic separation distance, ensuring that the rubber material on the magnetic separation conveyor belt can all undergo magnetic separation operations. The first magnetic blocks in the first magnetic separation roller, the second magnetic separation roller, the third magnetic separation roller, and the fourth magnetic separation roller are adjusted according to their positions. The metal filaments and fine wires adsorbed on the first magnetic separation roller and the second magnetic separation roller can be transferred to the third magnetic separation roller and the fourth magnetic separation roller, and the metal filaments and fine wires on the third magnetic separation roller and the fourth magnetic separation roller can be adsorbed and transferred by the second magnetic separation member.

[0016] Further, the second magnetic separation member is installed above the first magnetic separation member and is arranged in parallel with the upper surface of the magnetic separation conveyor belt. The movement direction of the second magnetic separation member is perpendicular to the conveying direction of the magnetic separation conveyor belt. The second magnetic separation member includes a second magnetic separation frame, a second magnetic separation belt, and second magnetic blocks. The second magnetic separation frame is installed on the first magnetic separation frame and extends away from the vibration feeding belt side. The second magnetic separation belt is reciprocally rotationally installed on the second magnetic separation frame. The second magnetic blocks are fixed at both ends inside the second magnetic separation frame near the bottom and are arranged along the rotation axis of the second magnetic separation belt. The length of the second magnetic blocks is less than the length of the second magnetic separation frame. A metal material recovery member is further arranged below one end of the second magnetic separation frame away from the vibration feeding belt. A guiding plate in an L shape is correspondingly arranged on the top of the metal material recovery member for the second magnetic separation frame. The guiding plate has an upward opening and is arranged away from the first magnetic separation member. A gap is left between the top of the guiding plate and the bottom of the second magnetic separation belt, and it is fixed on the side wall of the first magnetic separation frame.

[0017] By adopting the above technical solution, the second magnetic separation member adsorbs and transfers the metal filaments and fine wires and recovers them through the metal material recovery member. The second magnetic separation member extends out of the magnetic separation conveyor belt through the second magnetic separation belt, preventing the adsorbed metal material from falling back onto the magnetic separation conveyor belt and continuing to be transported, ensuring the magnetic separation effect.

[0018] Further, a horizontal third magnetic separator is oppositely arranged at a position far from the first magnetic separator and the second magnetic separator at the discharge end of the magnetic separation conveyor belt. The height of the third magnetic separator is lower than the height of the discharge end of the magnetic separation conveyor belt. The third magnetic separator includes a third magnetic separation frame, a third magnetic separation belt, and third magnetic blocks. The third magnetic separation belt is reciprocally rotatably installed on the third magnetic separation frame and is horizontally arranged. The third magnetic blocks are arranged at one end of the third magnetic separation frame close to the magnetic separation conveyor belt. The third magnetic blocks are arc-shaped and the length direction of the third magnetic blocks is arranged along the rotation axis of the third magnetic separation belt. A plurality of conveying partitions are also arranged on the outer circumference of the third magnetic separation belt in a circumferential array. The conveying partitions are arranged along the width direction of the third magnetic separation frame.

[0019] By adopting the above technical solution, the third magnetic separator is oppositely arranged with the first magnetic separator and the second magnetic separator. After passing through the first magnetic separator and the second magnetic separator, the materials are continuously conveyed to the end by the magnetic separation conveyor belt and freely fall. During this process, the third magnetic separator receives and adsorbs the metal materials with rubber materials adhered to their surfaces. Since they are adhered with more rubber materials, they are not easily adsorbed upward. However, the metal materials will be deflected under the influence of magnetic attraction when falling, so they will fall into the side of the third magnetic separation belt and be stuck in the accommodation space formed by the conveying partitions and the third magnetic separation belt. Then, the third magnetic separation belt conveys the metal materials with rubber materials adhered to their surfaces into the subsequent equipment.

[0020] Further, the material return device includes a material return conveyor belt and a crushed material return belt. The material return conveyor belt is arranged below the material return discharge port and extends above the batching conveyor member. The crushed material return belt connects the third magnetic separation belt and the vibrating blanking belt. One end of the crushed material return belt extends and is arranged below the end of the third magnetic separation belt far from the magnetic separation conveyor belt, and the other end of the crushed material return belt extends and is arranged above the vibrating blanking belt.

[0021] By adopting the above technical solution, the material return conveyor belt recycles and crushes the unqualified rubber materials after vibrating screening to ensure the fine crushing of the rubber materials; the third magnetic separation belt conveys the metal materials with rubber materials adhered to their surfaces to the crushed material return belt and then conducts vibrating blanking again through the vibrating blanking belt, and then conducts magnetic separation operation again together with the newly crushed rubber materials.

[0022] Further, the fourth magnetic separator is arranged below the middle of the third magnetic separator and the magnetic separation conveyor belt. The fourth magnetic separator includes a fourth magnetic separation frame and two fourth magnetic separation rollers. The fourth magnetic separation rollers are installed on both sides inside the fourth magnetic separation frame and are arranged in an upper and lower staggered manner. The top of the fourth magnetic separation frame is provided with a rubber material inlet and the bottom is provided with a rubber material outlet connected to the material conveying device. Opposite sides of the fourth magnetic separation frame near the bottom are also provided with crushed material outlets. An L-shaped discharge chute is arranged below each fourth magnetic separation roller and is connected to the crushed material outlet. The openings of the two discharge chutes face away from each other.

[0023] By adopting the above technical solution, the rubber material that continues to be conveyed to the end of the magnetic separation conveyor belt and freely falls is subjected to rotary magnetic separation and blanking again by the fourth magnetic separation component. Some rubber material metal clusters that fail to be adsorbed by the third magnetic separation component can impact and break up the magnetic clusters when colliding with the fourth magnetic separation frame, and finally are adsorbed and separated by the fourth magnetic separation component and discharged through the crushing material outlet. The fine powder that has undergone multiple magnetic separations is sent out from the rubber material outlet and connected to the subsequent material conveying device.

[0024] Further, the material conveying device includes a screw conveyor and a pneumatic conveyor arranged underground. One end of the screw conveyor is connected to the rubber material outlet and the other end is connected to the pneumatic conveyor. The pneumatic conveyor is connected to the feeding end of the screening device, and a dust removal component is also arranged at the pneumatic conveyor.

[0025] By adopting the above technical solution, the screw conveyor and the pneumatic conveyor cooperate to send the magnetically separated rubber material to the screening device for sizing operation. The pneumatic conveyor also plays a role in cooling the rubber material, and better cooling of the rubber material is achieved through cold air. The pneumatic conveyor transfers in the middle before screening and reduces the dust in the rubber material through the dust removal component.

[0026] In summary, the technical solution of the present invention has the following advantages:

[0027] 1. The magnetic separation equipment for continuous production of recycled rubber provided by the present invention integrates a batching device, a production device and a post-treatment device to form the production and grading operations of rubber particles before refining of recycled rubber, effectively reducing the manual labor intensity, improving the production efficiency. The number of integrated equipment and the length of the overall production line are moderate, and multiple production devices are arranged side by side to work simultaneously, avoiding the mutual influence of each process equipment in case of failure due to the too long continuous production line of recycled rubber.

[0028] 2. The magnetic separation equipment for continuous production of recycled rubber provided by the present invention sends the rubber material to the magnetic separation device for multi-stage magnetic separation operation only after the qualified rubber material is screened during the crushing process. The unqualified particles are returned for crushing operation through the return device, ensuring the quality of the rubber material, ensuring that the size of the rubber particles in the subsequent magnetic separation device is uniform and as regular as possible. The return device is set to realize the repeated fine crushing of large particle rubber material, and the automatic return without manual return effectively realizes the automated production.

[0029] 3. The magnetic separation equipment for continuous production of recycled rubber provided by the present invention has multiple magnetic separation components arranged in a staggered manner and of different types, which can effectively remove the metal impurities in the rubber material, avoid affecting the quality of the rubber material, and collect the removed metal impurities for convenient recycling of the materials.

DETAILED DESCRIPTION

[0039] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] A magnetic separation device for continuous production of regenerated rubber, such as Figure 1As shown, it includes a batching device 1, multiple production devices 2, and a post-treatment device 6 arranged in sequence along the production process. In this embodiment, two parallel production devices 2 are taken as an example. The batching device 1 includes a feeding member 11, multiple parallel large bins 12, and multiple parallel batching bins 13. In this embodiment, three parallel large bins 12 and two parallel batching bins 13 are provided. The feeding member 11 is uniformly connected to the large bins 12 through a feeding conveyor belt 113. The multiple batching bins 13 are connected to the production device 2 through corresponding batching conveyor members 131. The number of production devices 2 is set corresponding to the number of batching bins 13. Each production device 2 includes a crushing device 3, a return material device 4, and a magnetic separation device 5. The feeding end of the crushing device 3 is connected to the batching conveyor member 131. The return material device 4 and the magnetic separation device 5 are both arranged beside the crushing device 3. The magnetic separation device 5 is connected to the post-treatment device 6. The post-treatment device 6 includes a material transportation device 61 and a screening device 62. The screening device 62 is arranged at the end of the material transportation device 61. The feeding conveyor belt 113, the bin transportation member 122, the batching conveyor member 131, etc. mentioned in this embodiment are all commonly used belt structures driven by motors that can rotate forward and backward in the prior art. Only a simple schematic is shown in the figures of this application, and their driving structures and working principles will not be elaborated.

[0041] As Figure 1 and Figure 2As shown in the figure, the feeding part 11 includes three cutting machines 111 and a direct feeding bin 112. The discharging ends of the three cutting machines 111 are connected to the same horizontal cutting conveyor belt 1111. The cutting conveyor belt 1111 transports the cut rubber blocks from left to right to the feeding conveyor belt 113. The conveying end of the cutting conveyor belt 1111 is arranged above the feeding conveyor belt 113 and the conveying direction of the cutting conveyor belt 1111 is perpendicular to the conveying direction of the feeding conveyor belt 113. One end of the feeding conveyor belt 113 extends to the bottom of the direct feeding bin 112 and the other end extends to the top of the rightmost large bin 12. The large bins 12 are arranged in an array perpendicular to the direction of the feeding conveyor belt 113. The end of the feeding conveyor belt 113 near the rightmost feeding bin is lower than the end near the large bin 12. Storage conveyor belts 121 are provided at the tops of adjacent large bins 12 and are arranged staggeredly up and down between adjacent storage conveyor belts 121. The conveying end of the feeding conveyor belt 113 extends above the storage conveyor belt 121. The height of the storage conveyor belt 121 on the side close to the feeding conveyor belt 113 is higher than the height of the storage conveyor belt 121 on the side far from the feeding conveyor belt 113. In this embodiment, that is, the height of the right storage conveyor belt 121 is higher than the height of the left storage conveyor belt 121. A plurality of large bins 12 are all connected to the batching bin 13 through the bin transportation parts 122. The bin transportation parts 122 include a horizontal belt arranged beside the plurality of large bins 12, a feeding belt perpendicular to the horizontal belt, and a distributing belt installed on the tops of the two batching bins 13. The large bins 12 can discharge materials uniformly onto the horizontal belt or discharge materials onto the horizontal belt in sequence. The horizontal belt then sends the materials to the feeding belt and distributes the materials to different batching bins 13 through the distributing belt. The batching bin 13 feeds the crushing device 3 through the batching conveying parts 131. The batching conveying parts 131 include a batching belt arranged at the bottom of the batching bin 13, a lifting belt perpendicular to the conveying direction of the batching belt, and a feeding belt. After the batching belt receives the materials, it lifts the materials through the lifting belt to the main feeding belt. Since the feeding belt also needs to cooperate with the return material device 4, it is twisted at a certain angle, which is convenient for the erection of the overall structure and also convenient for reducing the floor area. Raw materials are fed using different feeding parts 11 according to their types. Raw materials such as waste tires are selected for cutting and then fed after cutting. The already cut rubber blocks are fed and transported through the direct feeding bin 112. After the raw materials are supplied, they are stored in the large bins 12. According to the workload, the corresponding number of large bins 12 are stored. When in need of use, they are fed to the crushing device 3 through the bin transportation parts 122 and the batching conveying parts 131.

[0042] As Figure 1 , Figure 2 and Figure 4As shown, the material conveying device 61 includes a screw conveyor 611 and a pneumatic conveyor 612 arranged underground. One end of the screw conveyor 611 is connected to the rubber compound outlet 5412, and the other end is connected to the pneumatic conveyor 612. The pneumatic conveyor 612 is connected to the feeding end of the screening device 62, and a dust removal member 6121 is also provided at the pneumatic conveyor 612. The screw conveyor 611 and the pneumatic conveyor 612 cooperate to send the magnetically separated rubber compound to the screening device 62 for mesh classification operation. The pneumatic conveyor 612 also plays a role in cooling the rubber compound, achieving better cooling of the rubber compound through cold air. The pneumatic conveyor 612 transfers in the middle before screening and reduces the dust in the rubber compound through the dust removal member 6121.

[0043] As Figure 3 and Figure 4 shown, the crushing device 3 includes a crushing frame 31, two sets of paired crushing rollers 32, a crushing drive member 33 and a vibrating blanking belt 34. A crushing feed inlet 311 is provided at the top of the crushing frame 31, and a crushing discharge outlet 312 is opened at one side of the bottom. Both ends of each set of crushing rollers 32 are rotationally positioned and installed on the crushing frame 31, and a pair of crushing rollers 32 in the same group rotate relatively. The two sets of crushing rollers 32 are arranged up and down, and a shearing roller surface (not shown in the figure) is provided on the outer surface. The axes of the crushing rollers 32 are all arranged along the length direction of the crushing frame 31 and perpendicular to the length direction of the vibrating blanking belt 34. The crushing drive member 33 is installed on the crushing frame 31 and is arranged at the same end of the multiple sets of crushing rollers 32 to drive the multiple sets of crushing rollers 32 to rotate. The vibrating blanking belt 34 extends out from the bottom of the crushing frame 31, and the length direction of the vibrating blanking belt 34 is perpendicular to the axis direction of the crushing rollers 32. A return material discharge outlet 341 is provided at one end of the vibrating blanking belt 34 far from the crushing frame 31, and a screening discharge outlet 342 is provided on the side of one end of the vibrating blanking belt 34 far from the crushing frame 31. The distributed raw materials fall into the crushing frame 31 and are crushed by the multiple sets of crushing rollers 32. The crushed rubber compound falls on the vibrating blanking belt 34. The vibrating blanking belt 34 selects a sieve mesh with an appropriate aperture for vibrating screening and blanking. The rubber compound that meets the requirements is discharged through the screening discharge outlet 342 and enters the magnetic separation device 5 for subsequent magnetic separation, while the rubber compound that does not meet the diameter requirements is returned through the return material discharge outlet 341 and undergoes a further return material crushing operation through the return material device 4.

[0044] As Figure 2 , Figure 3 and Figure 4As shown in the figure, a magnetic separation conveyor belt 55 is provided on the side of the vibrating blanking belt 34 away from the batching conveyor 131. In this embodiment, the batching conveyors 131 are all arranged on the right side of the vibrating blanking belt 34. Therefore, a magnetic separation conveyor belt 55 is arranged in parallel on the left side of the vibrating blanking belt 34. The magnetic separation conveyor belt 55 is arranged along the length direction of the vibrating blanking belt 34. The feeding end of the magnetic separation conveyor belt 55 is close to the screening discharge port 342, and the discharging end of the magnetic separation conveyor belt 55 is close to the crushing device 3. The magnetic separation conveyor belt 55 is of an inclined structure, and the height of the feeding end of the magnetic separation conveyor belt 55 is lower than the height of the discharging end of the magnetic separation conveyor belt 55. A U-shaped baffle 551 is also arranged at the feeding end of the magnetic separation conveyor belt 55, and the baffle 551 is perpendicular to the upper surface of the magnetic separation conveyor belt 55. The qualified rubber materials are screened and then conveyed by the magnetic separation conveyor belt 55 into multiple magnetic separation components for magnetic separation operations. The magnetic separation conveyor belt 55 is inclined and a baffle 551 is arranged at the end to prevent the rubber materials from falling to the ground. The magnetic separation conveyor belt 55 conveys the rubber materials through the magnetic separation operations of the first magnetic separation component 51 and the second magnetic separation component 52. The magnetic separation conveyor belt 55 with low feeding can also prevent the rubber materials from rolling directly under the influence of gravity without passing through magnetic separation.

[0045] The magnetic separation device 5 includes a first magnetic separation component 51, a second magnetic separation component 52, a third magnetic separation component 53, and a fourth magnetic separation component 54 arranged along the material conveying direction. The second magnetic separation component 52 is installed above the first magnetic separation component 51 close to the third magnetic separation component 53. The third magnetic separation component 53 is arranged opposite to the first magnetic separation component 51 above the top of the fourth magnetic separation component 54. The discharging end at the bottom of the fourth magnetic separation component 54 is connected to the post-treatment device 6.

[0046] As Figure 2 and Figure 3 shown in the figure, the return material device 4 includes a return material conveyor belt 41 and a crushed material return belt 42. The return material conveyor belt 41 is arranged below the return material discharge port 341 and extends above the batching conveyor 131. The crushed material return belt 42 connects the third magnetic separation belt 532 and the vibrating blanking belt 34. One end of the crushed material return belt 42 extends and is arranged below the end of the third magnetic separation belt 532 away from the magnetic separation conveyor belt 55, and the other end of the crushed material return belt 42 extends and is arranged above the vibrating blanking belt 34. The return material conveyor belt 41 recycles and crushes the unqualified rubber materials after vibration screening to ensure the fine crushing of the rubber materials; the third magnetic separation belt 532 conveys the metal materials with rubber materials adhered to the surface to the crushed material return belt 42, and then performs vibrating blanking again through the vibrating blanking belt 34. Subsequently, it is magnetically separated again together with the newly crushed rubber materials.

[0047] As Figure 4 、 Figure 5 and Figure 6As shown in the figure, the first magnetic separation component 51 is installed in parallel on the magnetic separation conveyor belt 55. The first magnetic separation component 51 includes a first magnetic separation frame 511 and a first magnetic separation roller group 512. The first magnetic separation component 51 is arranged along the width direction of the magnetic separation conveyor belt 55. Both ends of the first magnetic separation roller group 512 are positioned and rotatably installed on the first magnetic separation frame 511, and the axial direction is perpendicular to the conveying direction of the magnetic separation conveyor belt 55. The magnetic separation conveyor belt 55 conveys the rubber material from the lower right to the upper left. The first magnetic separation roller group 512 includes a first magnetic separation roller 5121, a second magnetic separation roller 5122, a third magnetic separation roller 5123, and a fourth magnetic separation roller 5124 arranged in sequence along the conveying direction of the magnetic separation conveyor belt 55. Arc-shaped first magnetic blocks 5125 are installed near the bottom inside the first magnetic separation roller 5121, the second magnetic separation roller 5122, the third magnetic separation roller 5123, and the fourth magnetic separation roller 5124. The first magnetic separation roller group 512 includes four magnetic separation rollers. The multi-roller arrangement increases the magnetic separation distance to ensure that all the rubber material on the magnetic separation conveyor belt 55 can undergo magnetic separation operations. The first magnetic blocks 5125 inside the first magnetic separation roller 5121, the second magnetic separation roller 5122, the third magnetic separation roller 5123, and the fourth magnetic separation roller 5124 are adjusted according to their positions. The sizes and angles of the multiple first magnetic blocks 5125 are different. The first magnetic block 5125 inside the first magnetic separation roller 5121 is biased to the right and the angle is about 270°. The first magnetic block 5125 inside the second magnetic separation roller 5122 is biased towards the first magnetic separation roller 5121 and the angle is also about 270°. The first magnetic block 5125 inside the third magnetic separation roller 5123 is biased towards the second magnetic separation roller 5122 and the angle is 190 - 250°. The first magnetic block 5125 inside the fourth magnetic separation roller 5124 is symmetrically arranged left and right and the angle is smaller than the first magnetic block 5125 inside the third magnetic separation roller 5123. The angle of the first magnetic block 5125 inside the fourth magnetic separation roller 5124 is greater than 180°. The first magnetic blocks 5125 are all installed on the roller cores of the corresponding rollers. When the corresponding rollers rotate, only the outer cylinders rotate, and the first magnetic blocks 5125 do not rotate.

[0048] At the top of the first magnetic separation frame 511, material transfer openings 5111 are provided corresponding to the third magnetic separation roller 5123 and the fourth magnetic separation roller 5124. The material transfer openings 5111 are arranged along the length direction of the magnetic separation frame. A second magnetic separation component 52 is arranged in parallel above the material transfer openings 5111. The metal filaments and fine wires adsorbed on the first magnetic separation roller 5121 and the second magnetic separation roller 5122 can be transferred to the third magnetic separation roller 5123 and the fourth magnetic separation roller 5124, and the metal filaments or fine wires on the third magnetic separation roller 5123 and the fourth magnetic separation roller 5124 can be adsorbed and transferred by the second magnetic separation component 52.

[0049] The second magnetic separation component 52 is installed above the first magnetic separation component 51 and is arranged parallel to the upper surface of the magnetic separation conveyor belt 55. The moving direction of the second magnetic separation component 52 is perpendicular to the conveying direction of the magnetic separation conveyor belt 55. The second magnetic separation component 52 includes a second magnetic separation frame 521, a second magnetic separation belt 522, and second magnetic blocks 523. The second magnetic separation frame 521 is installed on the first magnetic separation frame 511 and the second magnetic separation frame 521 extends away from the vibrating blanking belt 34. The second magnetic separation belt 522 is reciprocally rotatably installed on the second magnetic separation frame 521. The two ends of the second magnetic blocks 523 are fixed near the bottom inside the second magnetic separation frame 521 and are arranged along the rotation axis of the second magnetic separation belt 522. The length of the second magnetic blocks 523 is less than the length of the second magnetic separation frame 521 and there are no second magnetic blocks 523 on the side away from the vibrating blanking belt 34. A metal material recovery component 5211 is further arranged below one end of the second magnetic separation frame 521 away from the vibrating blanking belt 34. An L-shaped material guiding plate 5212 is further arranged on the top of the metal material recovery component 5211 corresponding to the second magnetic separation frame 521. The material guiding plate 5212 has an upward opening and is arranged away from the first magnetic separation component 51. A gap is left between the top of the material guiding plate 5212 and the bottom of the second magnetic separation belt 522 and it is fixed on the side wall of the first magnetic separation frame 511. The top of the material guiding plate 5212 contacts the adhered metal filaments and scrapes them off and drops them into the metal material recovery component 5211. The material guiding plate 5212 does not directly contact the second magnetic separation belt 522 to avoid the surface of the second magnetic separation belt 522 being magnetized due to contact friction, which is not conducive to separating the metal filaments from the second magnetic separation belt 522. The second magnetic separation component 52 adsorbs and transfers the fine metal filaments and recovers them through the metal material recovery component 5211. The second magnetic separation component 52 extends out of the magnetic separation conveyor belt 55 through the second magnetic separation belt 522, preventing the adsorbed metal materials from falling back onto the magnetic separation conveyor belt 55 and continuing to be transported, ensuring the magnetic separation effect.

[0050] Such as Figure 4 , Figure 5 and Figure 6As shown, a horizontal third magnetic separator 53 is oppositely arranged at a position where the discharge end of the magnetic separation conveyor belt 55 is far from the first magnetic separator 51 and the second magnetic separator 52. The height of the third magnetic separator 53 is lower than the height of the discharge end of the magnetic separation conveyor belt 55. The third magnetic separator 53 includes a third magnetic separation frame 531, a third magnetic separation belt 532, and third magnetic blocks 533. The third magnetic separation belt 532 is reciprocally rotatably installed on the third magnetic separation frame 531 and the third magnetic separation belt 532 is horizontally arranged. In the illustrated position, the third magnetic separation belt 532 is transported from right to left. The third magnetic blocks 533 are arranged at one end of the third magnetic separation frame 531 close to the magnetic separation conveyor belt 55, that is, at the right end within the third magnetic separation belt 532. The third magnetic blocks 533 are arc-shaped and the length direction of the third magnetic blocks 533 is arranged along the rotation axis of the third magnetic separation belt 532. The third magnetic blocks 533 are installed on the axis core of the rotation shaft of the third magnetic separation belt 532. When driving the third magnetic separation belt 532 to rotate, it is the outer cylinder of the rotation shaft that rotates, but its axis core does not rotate. A plurality of conveying partitions 5321 are also arranged in a circumferential array on the outer periphery of the third magnetic separation belt 532. The conveying partitions 5321 are arranged along the width direction of the third magnetic separation frame 531. The third magnetic separator 53 is oppositely arranged with the first magnetic separator 51 and the second magnetic separator 52. After passing through the first magnetic separator 51 and the second magnetic separator 52, it is continuously conveyed to the end by the magnetic separation conveyor belt 55 and freely falls. During this process, the third magnetic separator 53 receives and adsorbs the metal materials with rubber materials adhered to their surfaces. Because they adhere more rubber materials themselves, they are not easily adsorbed upwards. However, the metal materials will be deflected under the influence of the magnetic attraction force when falling, so they will fall into the side of the third magnetic separation belt 532 and be stuck in the accommodation space formed by the conveying partitions 5321 and the third magnetic separation belt 532. After that, the third magnetic separation belt 532 conveys the metal materials with rubber materials adhered to their surfaces into the subsequent equipment.

[0051] As Figure 4 , Figure 5 and Figure 6As shown in the figure, the fourth magnetic separation component 54 is arranged below the middle part of the third magnetic separation component 53 and the magnetic separation conveyor belt 55. The fourth magnetic separation component 54 includes a fourth magnetic separation frame 541 and two fourth magnetic separation rollers 542. The fourth magnetic separation rollers 542 are installed on both sides inside the fourth magnetic separation frame 541 and are arranged vertically and staggeredly. The top of the fourth magnetic separation frame 541 is provided with a rubber material inlet 5411, and the bottom is provided with a rubber material outlet 5412 connected to the material conveying device 61. On the opposite sides of the fourth magnetic separation frame 541 near the bottom, there are also provided broken material outlets 5413. Below each fourth magnetic separation roller 542, there is an L-shaped discharge chute 5421 connected to the broken material outlet 5413. The openings of the two discharge chutes 5421 face away from each other. Inside each fourth magnetic separation roller 542, there is an arc-shaped fourth magnetic block 5422 installed. The arc-shaped convex surfaces of the two fourth magnetic blocks 5422 face each other, and the arc angles are both greater than 180°. The fourth magnetic block 5422 is installed at the axis core of the fourth magnetic separation roller 542. When the fourth magnetic separation roller 542 performs magnetic separation, the outer cylinder rotates, but its axis core does not rotate. The rubber material that continues to be conveyed to the end of the magnetic separation conveyor belt 55 and freely falls passes through the fourth magnetic separation component 54 again for rotational magnetic separation and blanking. Some rubber material metal clusters that fail to be adsorbed by the third magnetic separation component 53 can impact and disperse the magnetic clusters when colliding with the fourth magnetic separation frame 541, and finally are adsorbed and separated by the fourth magnetic separation component 54 and discharged through the broken material outlet 5413. The fine powder that has undergone multiple magnetic separations is sent out through the rubber material outlet 5412 and connected to the subsequent material conveying device 61.

[0052] The working principle and usage method of this magnetic separation equipment for continuous production of recycled rubber: Select whether to cut the raw materials into pieces by the cutting machine 111 or directly feed the feed bin 112 through the feed conveyor belt 113 to feed and store the large feed bin 12. The three large feed bins 12 are evenly stored through the storage belt to ensure sufficient supply to the batching bin 13. The large feed bin 12 is divided and transported to the batching bin 13 through the bin transportation component 122. The batching bin 13 feeds the materials to the crushing device 3 through the batching conveyor component 131 for crushing. The crushing device 3 crushes the coarse materials into fine materials and differentiates and discharges the materials through the vibrating blanking belt 34. The unqualified rubber materials are connected to the return conveyor belt 41 through the return material discharge port 341 for return material circulation. The qualified fine materials are discharged through the screening discharge port 342 and sent to the magnetic separation device 5 for magnetic separation operations. The magnetic separation first passes through the roller magnetic separation of the first magnetic separation component 51, and then transfers the metal filaments on the first magnetic separation component 51 to the second magnetic separation component 52. The second magnetic separation component 52 transfers the filament metals to the metal material recovery component 5211, and then the materials fall and pass through the third magnetic separation component 53 and the fourth magnetic separation component 54 for rotational magnetic separation. The rubber materials after magnetic separation are sent to the screening device 62 through the auger conveyor component 611 and the pneumatic conveyor component 612 for multi-stage screening, and finally are discharged according to the mesh number and stored waiting for the refining process.
