Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of waste tire treatment, and specifically relates to a recycling and reuse device for purifying carbon black from secondary pyrolysis of waste tires. Background Art
[0002] Currently, pyrolysis of waste tires is the most thorough method for treating waste tires. It has no pollutant emissions and can also recover fuel oil and carbon black, which is beneficial to environmental protection and resource utilization. Generally, waste tires need to be crushed, pyrolyzed, and cracked.
[0003] After pyrolyzing waste tires into waste tire powder, it is necessary to crack it to obtain carbon black. Currently, a cracking furnace is used for cracking.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.
[0021] Referring to Figures 1 - 11 , a recycling and reuse device for purifying carbon black from waste tire secondary pyrolysis includes a cracking furnace 1, and a conveying cylinder 2 is fixedly connected through the top inside the cracking furnace 1, and a storage tank 3 is fixedly connected through the top inside the conveying cylinder 2.
[0022] The inner wall of the cracking furnace 1 is fixedly connected with a heating ring 5 through a plurality of fixing plates 4. The lower end of the cracking furnace 1 is fixedly connected with a first motor 13. The movable end of the first motor 13 is fixedly connected with a vertical rod 14. The side wall of the vertical rod 14 is fixedly connected with a spiral conveyor blade 15. The side wall of the spiral conveyor blade 15 is in contact with the inner side wall of the heating ring 5. When cracking waste tire powder, drive the first motor 13 to rotate forward, drive the vertical rod 14 and the spiral conveyor blade 15 to rotate forward, continuously convey the waste tire powder from bottom to top, and the waste tire powder located above will fall through the outer side wall of the heating ring 5 for subsequent conveyance. In this way, the waste tire powder can be continuously conveyed from bottom to top, making the waste tire powder evenly heated. Under the action of the heating ring 5, the waste tire powder is cracked.
[0023] A one-way exhaust pipe 16 is fixedly communicated with the inner top of the cracking furnace 1 to discharge some waste gas in the cracking furnace 1. An outlet pipe 17 is fixedly communicated with the inner bottom of the cracking furnace 1. An electric butterfly valve is installed in the outlet pipe 17. After the waste tire powder is cracked into carbon black, at this time, open the electric butterfly valve and drive the first motor 13 to rotate reversely, drive the vertical rod 14 and the spiral conveyor blade 15 to rotate reversely, and continuously convey the waste tire powder from top to bottom and flow out through the outlet pipe 17.
[0024] The degassing mechanism, the degassing mechanism includes a hollow rod 6 rotatably connected to the inner wall of the conveying cylinder 2. A cylinder 7 is fixedly connected to the side wall of the hollow rod 6. The outer side wall of the cylinder 7 is in sealed sliding connection with the inner wall of the conveying cylinder 2. Four placement grooves 8 are opened on the side wall of the cylinder 7. The two placement grooves 8 located above and below are respectively opposite to the storage bin 3 and the cracking furnace 1. The inner walls of the four placement grooves 8 are all communicated with the inner wall of the hollow rod 6 through a plurality of air extraction pipes 11. An L-shaped plate 9 is fixedly connected to the side wall of the storage bin 3. A rigid pipe 10 is fixedly connected to the side wall of the L-shaped plate 9. The side wall of the rigid pipe 10 is in sealed rotational connection with the inner wall of the hollow rod 6. An air extraction groove 12 is opened on the inner wall of the rigid pipe 10 between the upper and lower placement grooves 8. It should be noted that the air extraction groove 12 is arranged 90 degrees clockwise along the upper placement groove 8 (as Figure 3 shown). It should be noted that filters are installed in the plurality of air extraction pipes 11 to prevent the materials in the placement grooves 8 from being sucked out.
[0025] In the present invention, the hollow rod 6 rotates intermittently clockwise by 90 degrees (as Figure 3As shown in the figure, during the rotation of the hollow rod 6, the rigid tube 10 does not rotate, that is, the position of the air extraction groove 12 remains unchanged. After the waste tire powder is stored in the placement groove 8 corresponding to the storage tank 3 and rotates clockwise by ninety degrees, a plurality of air extraction pipes 11 corresponding to the placement groove 8 are facing the air extraction groove 12. At this time, the rigid tube 10 can extract the air in the placement groove 8 through the air extraction groove 12 and the plurality of air extraction pipes 11, perform exhaust treatment on the placement groove 8. Subsequently, the hollow rod 6 rotates clockwise by ninety degrees again, rotates the exhausted placement groove 8 to face the cracking furnace 1, and then the waste tire powder enters the cracking furnace 1, realizing the avoidance of air entry during the feeding of the cracking furnace 1, effectively avoiding the reaction of the intermediate products generated during the cracking of the waste tire powder with the introduced air to generate dioxin.
[0026] A cleaning mechanism is provided on the cracking furnace 1. The cleaning mechanism includes a first plate 18 fixedly connected to the upper end of the cracking furnace 1 (as Figure 2 shown), a rectangular rod 19 is slidably connected to the side wall of the first plate 18 (as Figure 6 shown). A rectangular block 20 is fixedly connected to the side wall of the rectangular rod 19 close to the conveying cylinder 2. The side wall of the rectangular block 20 is elastically connected to the side wall of the first plate 18 through a plurality of springs 22. A first cleaning cotton 21 is fixedly connected to the side wall of the rectangular block 20. The side wall of the rectangular block 20 penetrates the side wall of the conveying cylinder 2 and faces one of the placement grooves 8. Two first guide rails 23 are fixedly connected to the side wall of the rectangular block 20 away from the rectangular rod 19. A moving plate 24 is slidably connected to the common side walls of the two first guide rails 23. A second cleaning cotton 25 is fixedly connected to the side wall of the moving plate 24.
[0027] A groove 26 is formed in the side wall of the rectangular block 20 away from the rectangular rod 19. A cross bar 27 is rotatably connected to the inner wall of the groove 26. A circular plate 28 is fixedly connected to the side wall of the cross bar 27 located in the groove 26. The side wall of the circular plate 28 away from the axis is rotatably connected to the side wall of the moving plate 24 through a rotating rod 29.
[0028] The side wall of the cross bar 27 is rotatably connected through the side wall of the rectangular rod 19. One end of the cross bar 27 away from the circular plate 28 is fixedly connected to a rifled rod 31. A second plate 30 is fixedly connected to the side wall of the L-shaped plate 9 (as Figure 7 shown). The side wall of the rifled rod 31 is threadedly connected to the side wall of the second plate 30.
[0029] When one of the placement grooves 8 is facing the rectangular block 20, at this time, the rectangular rod 19 moves towards the direction close to the placement groove 8, thereby driving the rectangular block 20 into the placement groove 8, so that the first cleaning cotton 21 cleans the inner side wall of the placement groove 8. During the process of the rectangular rod 19 moving and driving the rifled rod 31 to move, at this time, under the action of the second plate 30, the rifled rod 31 is driven to rotate continuously, and then the circular plate 28 is driven to rotate through the cross bar 27, so that the circular plate 28 drives the moving plate 24 to slide back and forth on the side walls of the two first guide rails 23 through the rotating rod 29, so that the second cleaning cotton 25 located on the side wall of the moving plate 24 moves back and forth to clean the inner wall of the placement groove 8 facing the rectangular block 20. In this way, the five inner walls of the placement groove 8 can be effectively cleaned, avoiding the adhesion of waste tire powder on the inner wall of the placement groove 8. After long-term use, there is a large amount of waste tire powder accumulated on the inner wall of the placement groove 8, resulting in a small feeding amount of waste tire powder.
[0030] The side wall of the L-shaped plate 9 is fixedly connected with a second motor 32 (as Figure 11 shown), the side wall of the movable shaft of the second motor 32 is fixedly connected with an incomplete gear 33, the side wall of the hollow rod 6 is fixedly connected with a first gear 34, and the incomplete gear 33 meshes with the first gear 34 during rotation. When the second motor 32 rotates counterclockwise (as Figure 5 shown), the incomplete gear 33 rotates counterclockwise and intermittently meshes with the first gear 34, thereby driving the first gear 34 to rotate intermittently clockwise by ninety degrees.
[0031] The inner top of the L-shaped plate 9 is fixedly connected with a second guide rail 35, the side wall of the second guide rail 35 is slidably connected with a first toothed plate 36, the side wall of the L-shaped plate 9 is rotatably connected with a second gear 37 through a rotating shaft, the side wall of the second gear 37 meshes with the side wall of the first toothed plate 36, and the incomplete gear 33 meshes with the second gear 37 during rotation. The side wall of the first toothed plate 36 is fixedly connected with the side wall of the rectangular rod 19 through a first Z-shaped rod 38.
[0032] When the incomplete gear 33 rotates counterclockwise and meshes with the second gear 37 (as Figure 7 shown), at this time, the rotation of the first gear 34 stops, that is, the rotation of the cylinder 7 stops. At this time, one of the placement grooves 8 faces the rectangular block 20. Since the second gear 37 rotates clockwise at this time, it drives the first toothed plate 36 to move to the right. Then, the first toothed plate 36 drives the rectangular rod 19 to move towards the direction close to the placement groove 8 through the first Z-shaped rod 38. When the incomplete gear 33 rotates counterclockwise and separates from the second gear 37, at this time, under the elastic force of the plurality of springs 22, the rectangular block 20, the rectangular rod 19 and the first toothed plate 36 are driven back to their original positions, completing the cleaning of the placement groove 8 and facilitating the next cleaning.
[0033] The mixing mechanisms are arranged on the plurality of fixing plates 4. The mixing mechanism includes strip-shaped cavities 39 (as Figure 9As shown in the figure, a plurality of driving rods 40 are rotatably connected to the inner walls of the plurality of strip-shaped cavities 39. A plurality of mixing plates 41 are fixedly connected to the outer side walls of the plurality of driving rods 40 located outside the fixing plate 4. A third plate 42 is hermetically and slidably connected to the lower parts of the inner walls of the plurality of strip-shaped cavities 39. A second toothed plate 43 is fixedly connected to the upper end of the third plate 42. Third gears 44 are fixedly connected to the side walls of the plurality of driving rods 40 located inside the strip-shaped cavities 39. The side wall of the second toothed plate 43 meshes with the side walls of the corresponding plurality of third gears 44.
[0034] A pump oil frame 45 is fixedly connected through the side wall of the first plate 18. A fourth plate 46 is hermetically and slidably connected to the inner wall of the pump oil frame 45. The side wall of the fourth plate 46 is fixedly connected to the side wall of the rectangular block 20 through a second Z-shaped rod 50. Flow pipes 49 are fixedly communicated with the lower parts of the inner walls of the plurality of strip-shaped cavities 39 (as Figure 10 shown in the figure). The common fixed communication of the ends of the plurality of flow pipes 49 far away from the strip-shaped cavities 39 forms an annular pipe 48. The inner wall of the pump oil frame 45 is communicated with the inner wall of the annular pipe 48 through a connecting pipe 47.
[0035] When the rectangular block 20 moves in the direction close to the placing groove 8, the fourth plate 46 is driven to move through the second Z-shaped rod 50, so that the space in the pump oil frame 45 increases. Then, oil is sucked from the plurality of strip-shaped cavities 39 through the connecting pipe 47, the annular pipe 48 and the plurality of flow pipes 49, driving the third plates 42 in the plurality of strip-shaped cavities 39 to move downward, so that the second toothed plate 43 drives the plurality of mixing plates 41 to rotate through the plurality of third gears 44 and the plurality of driving rods 40. When the rectangular block 20 moves in the direction away from the placing groove 8, the fourth plate 46 is driven to move through the second Z-shaped rod 50, so that the space in the pump oil frame 45 decreases. Then, oil is pumped from the plurality of strip-shaped cavities 39 through the connecting pipe 47, the annular pipe 48 and the plurality of flow pipes 49, driving the third plates 42 in the plurality of strip-shaped cavities 39 to move upward, so that the second toothed plate 43 drives the plurality of mixing plates 41 to rotate again through the plurality of third gears 44 and the plurality of driving rods 40, which can mix the waste tire powder flowing between the inner side wall of the cracking furnace 1 and the outer side wall of the heating ring 5 evenly, making it heat evenly.
[0036] When cracking the waste tire powder, the waste tire powder is added into the storage box 3. Subsequently, the waste tire powder will enter the placing groove 8 opposite to the storage box 3. Then, the second motor 32 is driven to rotate counterclockwise (as Figure 5As shown in FIG, the incomplete gear 33 rotates counterclockwise intermittently to mesh with the first gear 34, thereby driving the first gear 34 and the hollow rod 6 to rotate clockwise intermittently by ninety degrees. During the rotation of the hollow rod 6, the hard tube 10 does not rotate, that is, the position of the air extraction slot 12 remains unchanged. There is waste tire powder in the placement slot 8 corresponding to the storage box 3 and after rotating ninety degrees clockwise, the multiple air extraction pipes 11 corresponding to the placement slot 8 are facing the air extraction slot 12. At this time, the hard tube 10 can extract the air in the placement slot 8 through the air extraction slot 12 and the multiple air extraction pipes 11, and exhaust the air in the placement slot 8. Then the hollow rod 6 rotates clockwise again by ninety degrees, and the placement slot 8 after exhaust is rotated to face the cracking furnace 1. Then the waste tire powder enters the cracking furnace 1, thereby preventing the entry of air when feeding into the cracking furnace 1, and effectively preventing the intermediate products produced during the cracking of the waste tire powder from reacting with the air brought in to generate dioxins. At this time, when the waste tire powder is being cracked, the first motor 13 is driven to rotate forward, driving the vertical rod 14 and the spiral conveying blade 15 to rotate forward, and the waste tire powder is continuously conveyed from bottom to top, while the waste tire powder located above will fall through the outer wall of the heating ring 5 for later conveying. In this way, the waste tire powder can be continuously conveyed from bottom to top, so that the waste tire powder is heated evenly. Under the action of the heating ring 5, the waste tire powder is cracked, and the generated exhaust gas flows out through the one-way exhaust pipe 16; When the incomplete gear 33 rotates counterclockwise and meshes with the second gear 37 (as shown in FIG. Figure 7 As shown), at this time, the first gear 34 stops rotating, that is, the cylinder 7 stops rotating. At this time, one of the placement slots 8 is facing the rectangular block 20. Since the second gear 37 rotates clockwise at this time, it drives the first tooth plate 36 to move to the right. Then, the first tooth plate 36 drives the rectangular rod 19 to move toward the placement slot 8 through the first Z-shaped rod 38, driving the rectangular block 20 into the placement slot 8, so that the first cleaning cotton 21 cleans the inner wall of the placement slot 8. In the process of the movement of the rectangular rod 19 driving the rifle rod 31 to move, at this time, the second plate 30 acts on the second plate 30. Downward, the rifle rod 31 is driven to rotate continuously, and then the circular plate 28 is driven to rotate through the cross bar 27, so that the circular plate 28 drives the movable plate 24 to slide back and forth on the side walls of the two first guide rails 23 through the rotating rod 29, so that the second cleaning cotton 25 located on the side wall of the movable plate 24 moves back and forth to clean the inner wall of the placement groove 8 facing the rectangular block 20. In this way, the five surfaces of the inner wall of the placement groove 8 can be effectively cleaned to prevent the waste tire powder from adhering to the inner wall of the placement groove 8. After long-term use, the waste tire powder accumulated on the inner wall of the placement groove 8 is large, resulting in a small amount of waste tire powder feeding; When the incomplete gear 33 rotates counterclockwise and separates from the second gear 37, the elastic force of the multiple springs 22 drives the rectangular block 20, the rectangular rod 19 and the first tooth plate 36 back to their original positions, completing the cleaning of the placement slot 8 and facilitating the next cleaning. When the rectangular block 20 moves towards the direction close to the placement groove 8, the second Z-shaped rod 50 drives the fourth plate 46 to move, increasing the space inside the oil pumping frame 45. Then, through the connecting pipe 47, the annular pipe 48, and a plurality of flow pipes 49, oil is sucked from a plurality of strip-shaped cavities 39, driving the third plate 42 in the plurality of strip-shaped cavities 39 to move downward. As a result, the second toothed plate 43 drives a plurality of mixing plates 41 to rotate through a plurality of third gears 44 and a plurality of driving rods 40. When the rectangular block 20 moves away from the placement groove 8, the second Z-shaped rod 50 drives the fourth plate 46 to move, reducing the space inside the oil pumping frame 45. Then, through the connecting pipe 47, the annular pipe 48, and a plurality of flow pipes 49, oil is pumped from a plurality of strip-shaped cavities 39, driving the third plate 42 in the plurality of strip-shaped cavities 39 to move upward. As a result, the second toothed plate 43 drives a plurality of mixing plates 41 to rotate again through a plurality of third gears 44 and a plurality of driving rods 40, which can mix the waste tire powder flowing between the inner side wall of the cracking furnace 1 and the outer side wall of the heating ring 5 evenly, making it heat evenly; After the waste tire powder is cracked into carbon black, the electric butterfly valve is opened at this time, and the first motor 13 is driven to rotate reversely, driving the vertical rod 14 and the spiral conveying blade 15 to rotate reversely, continuously conveying the waste tire powder from top to bottom and flowing out through the discharge pipe 17.
