Description

Technical Field

[0002] In recent years, the amount of waste tires generated in my country has increased at an annual rate of 8-10%. In 2015, the amount of waste tires generated nationwide was about 330 million, weighing 12 million tons. In fact, waste tires are "full of treasures". They can be used to produce recycled rubber, rubber asphalt, waterproof materials and other products. At high temperatures, they can also be separated and extracted for gas, oil, carbon black, steel or directly used for thermal energy. The industrial potential is huge. Thermal cracking is currently the conventional method for recycling waste tires, and the cracking furnace is a necessary equipment for implementing this method.

[0003] However, when the existing waste rubber tire pyrolysis equipment is in use, its internal heating efficiency is low, which easily causes energy waste. After the waste tire is pyrolyzed, a large amount of residue will remain on its inner wall. When it accumulates to a certain thickness, it will greatly affect its heat conduction rate. Manual cleaning requires a lot of manpower and material resources, affecting work efficiency. In addition, the waste tire contains some steel wires, and it is very necessary to collect and utilize them.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 7 , the present invention provides a technical solution:

[0030] An environmentally friendly waste rubber tire cracking device comprises a support base 1, wherein the upper outer surface of the support base 1 is fixedly connected with a cracking furnace 2, the annular outer surface of the cracking furnace 2 is provided with a heat preservation furnace 3, a heating ring 4 is provided between the heat preservation furnace 3 and the cracking furnace 2, a feed pipe is embeddedly connected with a position near the left side of the upper outer surface of the cracking furnace 2, and an air outlet pipe is embeddedly connected with a position near the right side of the upper outer surface of the cracking furnace 2, a cleaning mechanism 5 is provided inside the cracking furnace 2, a collecting component 7 is fixedly connected with a position near the right side of the lower outer surface of the cracking furnace 2, and the cleaning mechanism 5 cooperates with the collecting component 7 to effectively clean the inside of the cracking furnace 2 and automatically discharge and collect the cleaned residue.

[0031] By adopting the above technical scheme, when working, waste rubber tires are put into the feed port, and then the feed port is closed, and the heating ring 4 is energized to heat the cracking furnace 2 to promote the cracking of tires in the cracking furnace 2. By annularly covering the cracking furnace 2, the temperature rise rate in the cracking furnace 2 is effectively improved, and by providing the insulation furnace 3, the heat loss can be reduced. After the cracking is completed, the cleaning mechanism 5 can be controlled to effectively clean the cracking furnace 2 to prevent the cracking residues from accumulating on the inner wall of the cracking furnace 2 and affecting the heat transfer rate. The collecting component 7 can effectively discharge the cracking residues from the inside of the cracking furnace 2, which greatly reduces the labor intensity of the staff and improves the work efficiency. The structure is simple and the practicability is strong.

[0032] As an embodiment of the present invention, Figure 2 , Figure 3 and Figure 4 As shown, the cleaning mechanism 5 includes a motor 51, a threaded rod 52, a slider 53, a slide groove 54, a support frame 55, a scraper block 56, and a scraping assembly 6. The motor 51 is fixedly connected to the center position of the upper outer surface of the cracking furnace 2, and the interior of the cracking furnace 2 is rotatably connected to the threaded rod 52 through a bearing. The output shaft of the motor 51 is fixedly connected to the threaded rod 52, and the position of the threaded rod 52 near the bottom end of the cracking furnace 2 is threadedly connected to the slider 53. The annular inner surface of the cracking furnace 2 is equidistantly provided with a plurality of groups of slide grooves 54. The annular outer surface of the slider 53 is fixedly connected to the support frame 55, and the support frame 55 and the slide groove 54 are matched with each other and slidably connected. The upper outer surface of the support frame 55 is fixedly connected to the scraper block 56 near the inner wall of the cracking furnace 2, and the scraping assembly 6 is arranged above the support frame 55.

[0033] By adopting the above technical solution, after the cracking is completed, the motor 51 is controlled to rotate, driving the threaded rod 52 to rotate. Since the threaded rod 52 is threadedly connected to the slider 53, the slider 53 is driven to move upward, and the support frame 55 is driven to move upward along the slide groove 54. The scraper block 56 then moves upward along the inner wall of the cracking furnace 2 to scrape and clean the inner wall of the cracking furnace 2, effectively cleaning the residue attached to the inner wall of the cracking furnace 2 to prevent the subsequent cracking work from being affected.

[0034] As an embodiment of the present invention, Figure 2 As shown, a filter plate 16 is fixedly connected to the upper part of the support frame 55 , and the filter plate 16 is designed as an inclined structure and matches the support frame 55 .

[0035] By adopting the above technical solution, when the support frame 55 moves upward, it can drive the filter plate 16 to move upward, effectively filter the cracking residue above it, separate the metal steel wire from the cracking carbon black, and effectively classify the cracking residue without the need for subsequent manual classification, thereby greatly improving work efficiency. The filter plate 16 is designed with an inclined structure, which can effectively prevent the cracking residue from accumulating in the middle of the filter plate 16.

[0036] As an embodiment of the present invention, Figure 6 As shown, the scraping assembly 6 includes a guide groove 61, a fixed rod 62, a gear 63, a scraper 64, and a gear ring 65. The guide groove 61 is opened at the right position of the inner surface of the cracking furnace 2, and the rear end of the inner surface of the guide groove 61 is opened with teeth. The support frame 55 extends to the inside of the guide groove 61, and the upper end outer surface thereof is fixedly connected with the fixed rod 62 near the position of the inner guide groove 61. The left outer surface of the fixed rod 62 is rotatably connected with the gear 63 near the upper end through a rotating shaft, and the right half of the gear 63 is meshed with the teeth. The annular outer surface of the slider 53 is rotatably connected with the scraper 64 near the upper end through a bearing, and the upper end outer surface of the scraper 64 is fixedly connected with the gear ring 65 at a position corresponding to the gear 63, and the left half of the gear 63 is meshed with the gear ring 65.

[0037] By adopting the above technical solution, when the support frame 55 moves upward, it can drive the fixed rod 62 to move upward, and the gear 63 moves upward accordingly. Since the gear 63 is meshed with the teeth inside the guide groove 61, the gear 63 will rotate. Since the left half of the gear 63 is meshed with the gear ring 65, the scraper 64 will be driven by the gear ring 65 to scrape and clean the upper outer surface of the filter plate 16, which can prevent the accumulation of cracked carbon black on its upper outer surface and accelerate the filtration rate of the cracked carbon black. At the same time, the metal steel wires are scraped together to facilitate their collection and processing later.

[0038] As an embodiment of the present invention, Figure 2 , Figure 4 and Figure 5As shown, the collecting assembly 7 includes a guide box 71, a through groove 72, a fixed block 73, a limiting groove 74, a limiting rod 75, and a bottom plate 76. The guide box 71 is fixedly connected to the outer surface of the lower end of the cracking furnace 2 near the right side, and a through groove 72 is provided on the outer surface of the bottom end of the cracking furnace 2 at a position corresponding to the guide box 71. A fixed block 73 is fixedly connected to the position near the bottom of the slider 53 on the threaded rod 52. A limiting groove 74 is provided on the outer surface of the lower end of the fixed block 73. The limiting groove 74 is designed as a wavy structure. The inner part of the limiting groove 74 is slidably connected to the limiting rod 75. The limiting rod 75 penetrates the cracking furnace 2 and is slidably connected to the cracking furnace 2, and extends to the inside of the guide box 71. The bottom end of the inner surface of the guide box 71 is slidably connected to the bottom plate 76, and the limiting rod 75 is fixedly connected to it.

[0039] By adopting the above technical scheme, when the cracking carbon black falls into the guide box 71, since the bottom plate 76 is designed as an inclined structure, it will flow out of the cracking furnace 2 along the bottom plate 76, which greatly facilitates the staff to collect it, and when the threaded rod 52 rotates, it will drive the fixed block 73 to rotate, and the limiting groove 74 will follow the rotation. Since the limiting groove 74 is designed as a wavy structure, it will resist the limit rod 75 inside it to make up and down reciprocating motion, and will drive the bottom plate 76 fixedly connected thereto to make up and down reciprocating motion, which can effectively shake off the cracking carbon black inside it, prevent it from being blocked during the discharge process, and ensure the normal discharge of the cracking carbon black.

[0040] As an embodiment of the present invention, Figure 2 As shown, a sealing block 8 is fixedly connected to the lower end of the support frame 55 , and the sealing block 8 and the through groove 72 are both T-shaped structures and match each other.

[0041] By adopting the above technical solution, when the support frame 55 moves upward, it will drive the sealing block 8 to move upward and automatically open the through groove 72, which is conducive to the cracking carbon black flowing into the collection component 7 through the through groove 72 and then discharged, which is convenient for the staff to collect and process. When the support frame 55 moves downward, it can drive the sealing block 8 to automatically close the through groove 72, and the T-shaped structure design of the two greatly improves the sealing between them.

[0042] As an embodiment of the present invention, Figure 2 and Figure 3 As shown, a cleaning plate 15 is fixedly connected to the left outer surface of the fixed block 73, and the cleaning plate 15 matches and is close to the bottom end of the inner surface of the cracking furnace 2.

[0043] By adopting the above technical solution, when the fixed block 73 rotates, it can drive the cleaning plate 15 fixedly connected thereto to make a circular motion around the threaded rod 52, so as to scrape the cracking carbon black that falls to the bottom of the cracking furnace 2. When the cleaning plate 15 makes a circular motion and passes over the through groove 72, the carbon black can be effectively scraped into the through groove 72, so that the user can handle it conveniently and prevent the carbon black from accumulating at the bottom of the cracking furnace 2.

[0044] As an embodiment of the present invention, Figure 7 As shown, the front end outer surface of the cracking furnace 2 is embedded and fixedly connected with a guide rail 9, the lower end outer surface of the guide rail 9 is fixedly connected to a collecting box 10 at a position close to the outer wall of the insulation furnace 3, and the two are connected to each other, the interior of the guide rail 9 is rotatably connected with a threaded rod 11 through a bearing, the rear end of the threaded rod 11 is fixedly connected with a bevel gear 12, the outer surface of the threaded rod 152 is fixedly connected with a bevel gear 13 at a position corresponding to the bevel gear 12, and the bevel gear 13 is meshed with the bevel gear 12, and a magnet block 14 is threadedly connected to the threaded rod 11 at a position close to the left side of the inside of the guide rail 9, and the magnet block 14 matches the guide rail 9.

[0045] By adopting the above technical scheme, when the cleaning mechanism 5 is controlled to rise to clean the inside of the cracking furnace 2, the rotation of the threaded rod 1 52 can drive the bevel gear 2 13 to rotate, which will drive the bevel gear 12 to rotate, and the threaded rod 2 11 will rotate accordingly, which will drive the magnet block 14 threadedly connected thereto to move to the right along the inside of the guide rail 9 until it enters the inside of the cracking furnace 2. When the scraper 64 scrapes the metal steel wire together and moves upward synchronously to approach the magnet block 14, the magnet block 14 can effectively adsorb the metal steel wire on the outer surface of its lower end. When the control motor 51 is reversed, the cleaning mechanism 5 moves downward accordingly, and the magnet block 14 moves to the left and resets accordingly. When it moves to the left above the collection box 10 and continues to move to the left, under the action of scraping the outer surface of the lower end of the guide rail 9, a large amount of metal steel wire can be effectively scraped off and dropped into the inside of the collection box 10, which greatly facilitates the collection and processing of the staff and has high practicality.

[0046] Working principle: When working, put the waste rubber tire into the feed port, then close the feed port, energize the heating coil 4, heat the cracking furnace 2, promote the tire cracking in the cracking furnace 2, and effectively improve the temperature rise rate in the cracking furnace 2 by annularly covering the cracking furnace 2. And by providing the heat preservation furnace 3, the heat loss can be reduced. After the cracking is completed, the motor 51 is controlled to rotate, driving the threaded rod 52 to rotate. Since the threaded rod 52 is threadedly connected with the slider 53, the slider 53 is driven to move upward, and the support frame 55 is driven to move upward along the slide 54. The scraper block 56 moves upward along the inner wall of the cracking furnace 2 to scrape and clean the inner wall of the cracking furnace 2, effectively cleaning the residue attached to the inner wall of the cracking furnace 2, and when the support frame 55 rises, the scraper block 56 moves upward along the inner wall of the cracking furnace 2 to scrape and clean the residue attached to the inner wall of the cracking furnace 2. At the same time, it can drive the filter plate 16 to move upward, effectively filter the pyrolysis residue above it, separate the metal steel wire from the pyrolysis carbon black, and effectively classify the pyrolysis residue without the need for manual classification in the later stage, which greatly improves the work efficiency. When the support frame 55 moves upward, it can drive the fixing rod 62 to move upward, and the gear 63 moves upward accordingly. Since the gear 63 is meshed with the teeth inside the guide groove 61, the gear 63 will rotate. Since the left half of the gear 63 is meshed with the gear ring 65, the scraper 64 will be driven by the gear ring 65 to scrape and clean the outer surface of the upper end of the filter plate 16, which can prevent the pyrolysis carbon black from accumulating on its upper end outer surface and accelerate the filtration rate of the pyrolysis carbon black. At the same time, the metal steel wire is scraped together, and the support frame 55 can be easily removed. When the support frame 55 moves upward, it will drive the sealing block 8 to move upward, automatically opening the through groove 72, which is conducive to the cracking carbon black flowing into the collecting assembly 7 through the through groove 72, and the cracking carbon slag that falls through the screen falls to the bottom of the cracking furnace 2. When the fixed block 73 rotates, it can drive the cleaning plate 15 fixedly connected thereto to make a circular motion around the threaded rod 52 to scrape the cracking carbon black that falls to the bottom of the cracking furnace 2. When the cleaning plate 15 makes a circular motion and passes above the through groove 72, it can effectively scrape the carbon black into the through groove 72, which is convenient for users to handle it and prevent the carbon black from accumulating at the bottom of the cracking furnace 2. When the cracking carbon black falls into the guide box 71, since the bottom plate 76 is designed as an inclined structure, it will flow out of the cracking furnace 2 along the bottom plate 76, which greatly facilitates the staff to handle it. When the threaded rod 52 rotates, the fixed block 73 is driven to rotate, and the limiting groove 74 rotates accordingly. Due to the wavy structure design of the limiting groove 74, the limiting rod 75 inside it will be resisted from reciprocating up and down, and the bottom plate 76 fixedly connected thereto will be driven to reciprocate up and down, which can effectively shake off the cracking carbon black inside it to prevent it from being blocked during the discharge process, thereby ensuring the normal discharge of the cracking carbon black. When the cleaning mechanism 5 is controlled to rise to clean the inside of the cracking furnace 2, the rotation of the threaded rod 52 can drive the bevel gear 13 to rotate, which will drive the bevel gear 12 to rotate, and the threaded rod 11 will rotate accordingly, which will drive the magnet block 14 threadedly connected thereto to move to the right along the inside of the guide rail 9 until it enters the inside of the cracking furnace 2.When the scraper 64 scrapes the metal wires together and moves upward synchronously to approach the magnet block 14, the magnet block 14 can effectively adsorb the metal wires on its lower outer surface. When the control motor 51 is reversed, the cleaning mechanism 5 moves downward, and the magnet block 14 moves to the left and resets. When it moves to the left above the collection box 10, under the action of the scraping of the lower outer surface of the guide rail 9, a large amount of metal wires can be effectively scraped down and dropped into the collection box 10, which greatly facilitates the collection and processing of the staff. The overall structure is simple and practical.
