[0002] In today's era, with the rapid expansion of road traffic networks, asphalt mixtures, as the core material in road paving projects, are increasingly widely used. However, while asphalt mixtures help traffic development, they also bring a heavy burden to the ecological environment. When heating asphalt, a large amount of energy resources are often consumed, and a large amount of smoke and harmful gases such as sulfur dioxide and nitrogen oxides are also generated, which not only causes a sharp deterioration in the surrounding air quality, posing a serious threat to people's health, but also exacerbates the global greenhouse effect.

[0003] At the same time, with the booming development of the global automobile industry, the amount of waste tires is increasing day by day. Waste tires are not only difficult to degrade naturally, but also easily cause long-term and serious pollution to soil and water bodies by landfilling, incineration and other treatment methods. Landfilling leads to waste of land resources and high potential pollution risks, while incineration releases a large amount of harmful gases, aggravating air pollution.

[0032] The embodiments of the present application disclose a production device and method for an environmentally friendly asphalt mixture.

[0033] Example 1 Please refer to Figures 1 to 8 In one embodiment of the present application, an environmentally friendly asphalt mixture production device includes a reactor 100, a driving pipe 101 penetrating the bottom of the reactor 100 is provided at the center, a driving shaft 102 is rotatably connected to the driving pipe 101, and the driving pipe 101 and the driving shaft 102 are connected to the same driving assembly 200 at one end near the bottom of the reactor 100, the driving pipe 101 and the driving shaft 102 are synchronously reversely connected, and a reactor cover 103 is detachably connected to the top of the reactor 100, and a crushing device 200 is installed on the reactor cover 103 that is simultaneously connected to the driving pipe 101 and the driving shaft 102. Component 300, a first material preparation component 400 is installed on the crushing component 300, a second material preparation component 500 connected to the interior of the reactor 100 is installed on the kettle cover 103, the second material preparation component 500 is connected to the first material preparation component 400, the first material preparation component 400 is connected to the exhaust gas treatment component 600, the interior of the reactor 100 is located on the driving pipe 101 and is rotatably connected to the driving shaft 102, an electric heating component 800 is arranged on the inner wall of the reactor 100, and a discharging component 900 connected to the driving component 200 is arranged at the bottom of the reactor 100.

[0034] The implementation principle of the production device of the environmentally friendly asphalt mixture in the embodiment of the present application is: The first material preparation component 400 is used to put in solid raw materials such as waste tire blocks, and the second material preparation component 500 is used to put in liquid or powdered raw materials such as asphalt raw materials and chemical additives. During the raw material input process, the driving component 200 is started and controlled to rotate forward, and the driving component 200 will simultaneously drive the crushing component 300, the stirring component 700, and the discharging component 900 to operate forward. Solid raw materials such as waste tire blocks will enter the crushing component 300 through the first material preparation component 400, and the crushing component 300 will crush the solid raw materials such as waste tire blocks, and the crushed solid raw materials such as waste tire blocks will enter the reactor 100 through the crushing component 300. At the same time, liquid or powdered asphalt raw materials and chemical additives are continuously put into the reactor 100 from the second material preparation component 500. During the working process, the exhaust gas treatment component 600 can collect and treat the harmful gases or odorous gases volatilized when the raw materials are put in, so as to prevent environmental pollution. The stirring component 700 fully stirs the mixed raw materials in the reactor 100. At the same time, the electric heating component 800 provides a suitable reaction temperature for the mixture in the reactor 100, promoting a mixing reaction between the waste tires, asphalt raw materials and chemical additives to form an environmentally friendly asphalt mixture. When the reaction reaches the set time and the mixture is prepared, the driving component 200 changes the transmission direction and drives the discharging component 900 to work. The discharging component 900 discharges the prepared asphalt mixture from the bottom of the reactor 100 for subsequent use.

[0035] Please refer to Figures 1 to 8 In one embodiment of the present application, the driving assembly 200 includes a power member 201, the output shaft of the power member 201 is transmission-connected with a driving shaft 202, the driving shaft 202 is rotationally connected to the bottom of the reactor 100, a first driving bevel gear 203 is fixedly mounted on the driving shaft 202, a first driven bevel gear 204 meshing with the first driving bevel gear 203 is mounted on the driving tube 101, the outer end of the driving shaft 102 passing through the first driven bevel gear 204 is fixedly connected with a second driven bevel gear 205, the second driven bevel gear 205 is meshed with the first driving bevel gear 203, a third driven bevel gear 206 meshing with both the first driven bevel gear 204 and the second driven bevel gear 205 is fixedly mounted on the discharging assembly 900, the first driven bevel gear 204 is coaxially symmetrically arranged with the second driven bevel gear 205, and the third driven bevel gear 206 is coaxially symmetrically arranged with the first driving bevel gear 203.

[0036] During operation, the power member 201 first drives the driving shaft 202 to rotate in the forward direction, and the first driving bevel gear 203 fixed on the driving shaft 202 rotates accordingly. Since the first driving bevel gear 203 is meshed with the first driven bevel gear 204 on the driving tube 101, the first driven bevel gear 204 is driven to rotate, and then the driving tube 101 starts to rotate. At the same time, the first driving bevel gear 203 is meshed with the second driven bevel gear 205 at the outer end of the driving shaft 102, and the first driven bevel gear 204 and the second driven bevel gear 205 are coaxially symmetrically arranged, which ensures that the driving tube 101 and the driving shaft 102 can achieve synchronous reverse rotation. Furthermore, the first driven bevel gear 204 and the second driven bevel gear 205 will drive the third driven bevel gear 206 to rotate in the opposite direction to the first driving bevel gear 203 during the forward rotation, thereby driving the discharging assembly 900 to rotate in the opposite direction. At this time, the discharging assembly 900 will reversely transport the material entering it to the interior of the reactor 100. After the asphalt mixture is prepared, as long as the power part 201 is controlled to drive the driving shaft 202 to rotate in the opposite direction, the discharging assembly 900 will rotate forward, and the forward rotation of the discharging assembly 900 will output the material entering it from the interior of the reactor 100.

[0037] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the power component 201 is configured as an electric motor, a driving pulley 207 is fixedly installed on the output shaft of the motor, a driven pulley 208 is fixedly installed on the driving shaft 202 corresponding to the driving pulley 207, and a belt 209 is connected between the driven pulley 208 and the driving pulley 207.

[0038] During operation, the motor as the power part 201 can drive the driving pulley 207 to rotate. The driving pulley 207 is connected to the driven pulley 208 installed on the driving shaft 202 through the belt 209. According to the belt transmission principle, the rotation of the driving pulley 207 is transmitted to the driven pulley 208 with the help of the belt 209, thereby driving the driving shaft 202 to rotate. The belt transmission has certain elasticity and slip characteristics. When the motor is suddenly started or the load increases instantly, the belt 209 can slip to avoid the rigid impact being transmitted to the subsequent bevel gear transmission system and other components, play a buffering and overload protection role, and effectively extend the service life of the entire drive component.

[0039] Please refer to Figures 1 to 8In one embodiment of the present application, the crushing assembly 300 includes an outer cylinder 301, which is fixedly connected to the kettle cover 103. A crushing ring 302 is slidably connected to the inner side of the outer cylinder 301. The inner side of the crushing ring 302 is set near the bottom thereof as a conical surface 303, and the conical surface is provided with crushing teeth 304 evenly distributed in an annular shape. A crushing cone 305 is fixedly installed on the outer side of the driving pipe 101 that passes through the center of the crushing ring 302, corresponding to the conical surface 303. The crushing cone 305 is eccentrically arranged, and the outer side of the crushing cone 305 is close to the top thereof. A shearing groove 306 is provided at the position corresponding to the crushing tooth 304, and the top of the crushing cone 305 is rotatably connected to a shearing disk 307 fixedly installed on the driving shaft 102, and the shearing disk 307 is provided with a shearing opening 308 corresponding to the shearing groove 306; an oblique groove 309 is provided on the outer cylinder 301, and an adjusting rod 310 is fixedly connected to the crushing ring 302, and an adjusting handle 311 is screwed on the outer end of the adjusting rod 310 that passes through the oblique groove 309, and a friction pad 312 mounted on the adjusting rod 310 is abutted and connected between the adjusting handle 311 and the outer wall of the outer cylinder 301.

[0040] During operation, after the drive assembly 200 is started, it will drive the drive shaft 102 and the drive tube 101 to rotate synchronously in opposite directions. The drive tube 101 will drive the eccentrically arranged crushing cone 305 to rotate, and the drive shaft 102 will drive the shear disk 307 to rotate.

[0041] Solid raw materials such as scrap tire pieces in the first material preparation component 400 will enter between the shearing opening 308 on the shearing disk 307 and the shearing groove 306 on the crushing cone 305 under the action of their own gravity. Under the synchronous reverse rotation of the crushing cone 305 and the shearing disk 307, the solid raw materials such as scrap tire pieces in the shearing opening 308 and the shearing groove 306 will be subjected to shear force and complete preliminary crushing. When the material after preliminary crushing enters the area between the crushing ring 302 and the crushing cone 305. Due to the eccentric rotation of the crushing cone 305, the shearing groove 306 on the outside thereof and the crushing teeth 304 on the inner side cone surface 303 of the crushing ring 302 continuously interact with each other. As the crushing cone 305 rotates, the material is squeezed and scraped between the crushing teeth 304 and the crushing cone 305 and is crushed into smaller particles, and then falls into the interior of the reactor 100.

[0042] The degree of crushing of the material can be adjusted by operating the adjustment handle 311. When adjusting, the adjustment handle 311 is first rotated in the opposite direction with the central axis of the adjustment handle 311 as the center. Since the adjustment rod 310 passes through the oblique groove 309 and is screwed with the adjustment handle 311, the adjustment handle 311 will move radially away from the crushing ring 302 under the action of the thread, loosening the squeeze on the friction pad 312, thereby releasing the lock on the adjustment rod 310. After releasing the lock on the adjustment rod 310, the adjustment handle 311 is rotated along the oblique groove 309 with the central axis of the crushing ring 302 as the center, which will drive the crushing ring 302 to rotate inside the outer cylinder 301, thereby adjusting the gap between the crushing ring 302 and the crushing cone 305. After the adjustment is completed, the adjustment handle 311 is rotated forward with the central axis of the adjustment handle 311 as the center, so that the end of the adjustment handle 311 pushes the friction pad 312 to fit tightly against the outer wall of the outer cylinder 301, thereby locking the crushing ring 302 inside the outer cylinder 301.

[0043] When the adjusting rod 310 rotates to the highest point close to the oblique groove 309, the gap between the crushing ring 302 and the crushing cone 305 is the largest; when the adjusting rod 310 rotates to the lowest point close to the oblique groove 309, the gap between the crushing ring 302 and the crushing cone 305 is the smallest; by changing the gap between the crushing ring 302 and the crushing cone 305, the crushing requirements of raw materials of different hardness and size can be met, and the crushing effect can be optimized.

[0044] Please refer to Figures 1 to 8 In one embodiment of the present application, the first material preparation component 400 includes a first outer bucket 401, which is installed on the top of the outer cylinder 301, and the first outer bucket 401 is sealed inside with a first inner bucket 402. The first outer bucket 401 is made of heat insulating material, and the first inner bucket 402 is made of heat conductive material. A first heat conductive space 403 is formed between the first outer bucket 401 and the first inner bucket 402. The outer side of the first outer bucket 401 is connected to the exhaust gas treatment component 600 near the top of the first heat conductive space 403, and the outer side of the first outer bucket 401 is connected to the second material preparation component 500 near the bottom of the first heat conductive space 403.

[0045] During operation, the waste gas inside the reactor 100 enters the waste gas treatment component 600 through the second material preparation component 500 and the first material preparation component 400, and the heat emitted by the reactor 100 is also taken away. When the solid raw material (waste tire blocks) is poured into the first inner bucket 402 in the first outer bucket 401. Since the first inner bucket 402 is made of heat-conducting material, the first inner bucket 402 can absorb the heat emitted by the reactor 100. At the same time, the first outer bucket 401 is made of heat-insulating material, which can effectively reduce the heat loss from the first inner bucket 402 to the outside, so that the heat accumulates in the first inner bucket 402 and the first heat-conducting space 403 between the first inner bucket 402 and the first outer bucket 401. In this way, the raw materials can be preheated to a certain extent when passing through the first inner bucket 402, which helps to participate in the reaction faster in the reactor 100 and improve production efficiency.

[0046] Please refer to Figures 1 to 8 In one embodiment of the present application, the second material preparation component 500 includes a second outer bucket 501, which is fixedly installed on the kettle cover 103, and a second inner bucket 502 is installed inside the second outer bucket 501. The second outer bucket 501 is made of heat insulating material, and the second inner bucket 502 is made of heat conductive material. A second heat conduction space 503 is formed between the second outer bucket 501 and the second inner bucket 502. The second outer bucket 501 is connected to the interior of the reactor 100 near the bottom of the second heat conduction space 503, and a connecting pipe 504 is installed on the second outer bucket 501 near the top of the second heat conduction space 503. The end of the connecting pipe 504 away from the second outer bucket 501 is sealed and connected to a position on the first outer bucket 401 near the bottom of the first heat conduction space 403.

[0047] During operation, when liquid or powdered raw materials (such as asphalt raw materials, chemical additives) are poured into the second inner bucket 502 in the second outer bucket 501. The second inner bucket 502 is made of heat-conducting material and can absorb the heat generated when the reactor 100 is running. At the same time, the second outer bucket 501 is made of heat-insulating material, which can reduce internal heat loss, so that the heat is accumulated in the second inner bucket 502 and the second heat-conducting space 503 between the second inner bucket 502 and the second outer bucket 501. In this way, the raw materials can be preheated to a certain extent in the second inner bucket 502, which helps them to fuse faster after entering the reactor 100, thereby improving production efficiency. Under the action of gravity, the raw materials flow into the reactor 100 through the channel connected to the inside of the reactor 100 near the bottom of the second outer bucket 501 near the second heat-conducting space 503.

[0048] In addition, a connecting pipe 504 is installed at the top of the second outer bucket 501 near the second heat conduction space 503, and the connecting pipe 504 is sealed and connected to the position of the first outer bucket 401 near the bottom of the first heat conduction space 403. In this way, when the exhaust gas treatment component 600 is working, the exhaust gas inside the reactor 100 will enter the first heat conduction space 403 from the second heat conduction space 503 and finally enter the exhaust gas treatment component 600, and the heat carried by the exhaust gas will be transferred to the raw materials in the second inner bucket 502 and the first inner bucket 402 through the second heat conduction space 503 and the first heat conduction space 403, respectively, to achieve secondary utilization of heat, which is conducive to reducing the energy consumed by the reactor 100 to heat the raw materials, saving production costs, and improving energy utilization, which is in line with the concept of green production.

[0049] Please refer to Figures 1 to 8 In one embodiment of the present application, a feed motor 505 is fixedly and sealedly installed on the second outer bucket 501, and a feed shaft 506 is fixedly connected to the output shaft of the feed motor 505. The feed shaft 506 can rotatably pass through the side walls of the second outer bucket 501 and the second inner bucket 502, and a feed plate 507 is fixedly installed on the feed shaft 506 at a position inside the second inner bucket 502, and the outer side surface of the feed plate 507 is slidably connected to the inner side surface of the second inner bucket 502.

[0050] During operation, the feed motor 505 can drive the feed shaft 506 and the feed plate 507 to rotate inside the second inner bucket 502. When it is necessary to add liquid or powdered raw materials (such as asphalt raw materials, chemical additives, etc.) into the second material preparation component 500, the feed motor 505 is started. The feed motor 505 will drive the feed shaft 506 fixedly connected thereto to rotate synchronously, and the feed shaft 506 will drive the feed plate 507 to rotate. When the feed plate 507 rotates to be parallel to the axial direction of the second inner bucket 502, the liquid or powdered raw materials inside the second inner bucket 502 can automatically fall under the action of gravity. When the feed plate 507 rotates to be parallel to the radial direction of the second inner bucket 502, the liquid or powdered raw materials inside the second inner bucket 502 are blocked by the feed plate 507. When the feed plate 507 rotates continuously, the feed plate 507 will scrape the materials above it to below it, thereby realizing continuous quantitative feeding.

[0051] In one embodiment of the present application, the feed motor 505 is a stepper motor. The notable feature of the stepper motor is that it can convert electrical pulse signals into precise angular displacement or linear displacement. When conveying liquid or powdered raw materials to the second material preparation component 500, each time a pulse signal is received, the feed motor 505 will rotate a certain angle according to a fixed step angle, thereby driving the feed shaft 506 and the feed plate 507 to accurately push the raw materials. This allows the operator to accurately control the feed amount each time according to the production formula requirements, ensure the high precision of the raw material ratio, and help to ensure the production quality and stable performance of environmentally friendly asphalt mixtures.

[0052] Please refer to Figures 1 to 8 In one embodiment of the present application, the exhaust gas treatment component 600 includes an exhaust pipe 601, which is connected to the first heat-conducting space 403. One end of the exhaust pipe 601 is fixedly connected to the first outer bucket 401 near the top of the first heat-conducting space 403, and the end of the exhaust pipe 601 away from the first outer bucket 401 is connected to the exhaust gas treatment device.

[0053] During operation, when the raw materials inside the reactor 100 are mixed, volatile gases are continuously generated due to factors such as temperature and material properties, and the exhaust gas treatment device will extract the exhaust gas inside the first heat transfer space 403 through the exhaust pipe 601. After the exhaust gas inside the first heat transfer space 403 is extracted, a negative pressure will be formed, and then the exhaust gas inside the second heat transfer space 503 and the reactor 100 will be extracted through the connecting pipe 504. Finally, the odorous substances, harmful chemicals, etc. in the exhaust gas are effectively removed by the exhaust gas treatment device to ensure that the gas discharged to the external environment meets environmental protection standards. It effectively prevents the exhaust gas from leaking into the workshop environment, protects the health of the operators, and also prevents pollution to the surrounding atmospheric environment.

[0054] In a specific embodiment of the present application, the waste gas treatment device mainly includes an exhaust device, a filtering device, and an adsorption device. The exhaust device can be used to extract the waste to the filtering device and the adsorption device. The filtering device can filter the waste gas, and the adsorption device uses an adsorbent (such as activated carbon) to adsorb and purify the waste gas before discharging it. As a prior art, the waste gas treatment device will not be described in detail herein on its structural principle.

[0055] During operation, when the exhaust gas passes through the filter device, larger particles of impurities, dust, etc. are first intercepted by the coarse filter. As the exhaust gas goes deeper, finer particles will be captured by the subsequent finer filter. This helps to remove solid impurities in the exhaust gas, preventing them from clogging or affecting the treatment effect of subsequent adsorption and other treatment links, and can also purify some odorous substances. When the exhaust gas passes through the adsorption device, the harmful components in the exhaust gas (especially volatile organic compounds, or VOCs) will be adsorbed by the micropores on the surface of the activated carbon and attached to the activated carbon, thereby separating them from the exhaust gas. For example, for volatile aromatic substances such as benzene and toluene generated during the treatment of waste tires, activated carbon can effectively adsorb them and purify the exhaust gas.

[0056] Please refer to Figures 1 to 8 In one embodiment of the present application, the stirring assembly 700 includes a mounting cylinder 701, which is fixedly mounted on the driving tube 101, and a plurality of annularly evenly distributed stirring paddles 702 are rotatably connected to the side wall of the mounting cylinder 701, and a fourth driven bevel gear 703 is fixedly mounted on one end of the stirring paddle 702 located inside the mounting cylinder 701, and a second active bevel gear 704 is fixedly mounted on the driving shaft 102 at a position located inside the mounting cylinder 701, and the second active bevel gear 704 is meshed with the fourth driven bevel gear 703.

[0057] During operation, when the driving tube 101 and the driving shaft 102 rotate in opposite directions, the driving tube 101 will drive the stirring paddle 702 to revolve around the central axis of the driving tube 101 and the driving shaft 102 through the mounting tube 701. At the same time, the second active bevel gear 704 on the driving shaft 102 will drive the stirring paddle 702 to rotate around its own central axis through the fourth driven bevel gear 703. During the revolution and rotation, the stirring paddle 702 will repeatedly turn over, shear and mix the waste tire blocks, asphalt raw materials and chemical additives put into the reactor 100. On the one hand, the revolution of the stirring paddle 702 can push the materials to move in the horizontal direction, so that the materials at different positions can exchange positions with each other; on the other hand, the rotation of the stirring paddle 702 generates a vertical thrust on the materials, which can not only break up the agglomerated materials, but also prevent the materials from being deposited and stratified; it stably and reliably ensures the uniform mixing of various raw materials, which is conducive to accelerating the physical and chemical reactions and promoting the formation of environmentally friendly asphalt mixtures.

[0058] Please refer to Figures 1 to 8In one embodiment of the present application, the electric heating component 800 includes an electric heating tube 801, which is spirally arranged around the inner wall of the reactor 100, and an insulating tube 802 is embedded between the outer side of the electric heating tube 801 and the inner wall of the reactor 100. A heat-conducting tube 803 is inserted into the inner side of the electric heating tube 801, and both ends of the heat-conducting tube 803 and the heat-insulating tube 802 are sealed and connected. A temperature sensor 804 is fixedly and sealedly installed inside the reactor 100, and the temperature sensor 804 is electrically connected to a temperature controller, and the temperature controller is electrically connected to the electric heating tube 801.

[0059] During operation, when the mixture in the reactor 100 needs to be heated, the electric heating tube 801 is powered on and starts to work. Since the electric heating tube 801 is spirally arranged around the inner wall of the reactor 100, its heating area is large and can evenly dissipate heat to the surroundings. The heat is first transferred to the heat-conducting tube 803 in close contact with the electric heating tube 801. The heat-conducting tube 803, with its good thermal conductivity, quickly conducts the heat to the inside of the reactor 100, so that the mixture in the reactor is heated. At the same time, the temperature sensor 804 installed inside the reactor 100 monitors the temperature of the mixture in real time. The temperature sensor 804 transmits the detected temperature signal to the thermostat, and the temperature range suitable for the preparation of asphalt mixture is pre-set in the thermostat. When the temperature detected by the temperature sensor 804 is lower than the set lower limit, the thermostat keeps the electric heating tube 801 powered on to keep it heating; once the temperature reaches or exceeds the set upper limit, the thermostat immediately cuts off the power supply of the electric heating tube 801 and stops heating to prevent the performance of the mixture from being damaged due to overheating. In addition, an insulating tube 802 is embedded between the outer side surface of the electric heating tube 801 and the inner wall surface of the reactor 100. The insulating tube 802 can effectively prevent the heat generated by the electric heating tube 801 from dissipating to the outside of the reactor 100, so that the heat is concentrated in the reactor as much as possible, thereby improving energy utilization efficiency, reducing heat loss, and ensuring a stable and suitable heating environment for the mixture.

[0060] Please refer to Figures 1 to 8 In one embodiment of the present application, a discharging assembly 900 includes a discharging trough 901 fixedly connected to the bottom of the reactor 100, the discharging trough 901 is connected to the bottom of the reactor 100, the end of the discharging trough 901 away from the center of the reactor 100 is an open end, and the end of the discharging trough 901 close to the center of the reactor 100 is a closed end. The inside of the discharging trough 901 is rotatably connected to a transmission shaft 902, the outer end of the transmission shaft 902 passing through the closed end is fixedly connected to the third driven bevel gear 206, the transmission shaft 902 is located inside the discharging trough 901 and is fixedly connected to a spiral sheet 903, and the open end of the discharging trough 901 is fixedly connected to a discharging pipe 904.

[0061] During operation, when the output shaft of the power member 201 drives the driving shaft 202 to rotate, the first driving bevel gear 203 on the driving shaft 202 rotates, and then drives the third driven bevel gear 206 fixedly connected to the outer end of the transmission shaft 902 inside the discharge trough 901 to rotate, so that the transmission shaft 902 rotates synchronously. As the transmission shaft 902 rotates, the spiral piece 903 fixed on the outside thereof also rotates at high speed. The asphalt mixture will gather at the bottom of the reactor 100 under the action of gravity and flow into the inside of the discharge trough 901.

[0062] Since the rotation direction of the spiral blade 903 is fixed, during the preparation process of the asphalt mixture, the spiral blade 903 can drive the material entering the discharge trough 901 to move toward the end close to the center of the reactor 100 as long as the rotation direction of the power part 201 is controlled. The end of the discharge trough 901 close to the center of the reactor 100 is a closed end, so the material will flow from the end of the discharge trough 901 close to the center to the middle position of the reactor 100. In this way, the material can circulate inside the reactor 100 from the outside of the bottom of the reactor 100 to the center, and then from the bottom to the top, which promotes the stirring effect of the stirring assembly 700 and is also beneficial to improving the preparation of the asphalt mixture.

[0063] When the asphalt mixture in the reactor 100 is prepared, the power part 201 is controlled to rotate in the opposite direction, so that the spiral blade 903 drives the material entering the discharge trough 901 to move toward the end away from the center of the reactor 100. The rotating spiral blade 903 generates an axial outward thrust on the mixture entering the discharge trough 901, pushing the mixture to move along the discharge trough 901 toward the open end. When the mixture is pushed to the open end of the discharge trough 901 by the spiral blade 903, it is discharged through the discharge pipe 904 fixedly connected to the open end, and enters the subsequent collection, storage or direct use link, completing the entire discharge process.

[0064] Please refer to Figures 1 to 8 In one embodiment of the present application, the reactor 100 is fixedly installed with a gear box 210, and the gear box 210 covers the outer ends of the driving tube 101 and the driving shaft 102. The driving shaft 202 and the transmission shaft 902 are both rotatably connected to the side wall of the gear box 210, and the first driving bevel gear 203, the first driven bevel gear 204, the second driven bevel gear 205, and the third driven bevel gear 206 are all installed inside the gear box 210.

[0065] During operation, the gear box 210 is covered on the outer ends of the drive tube 101 and the drive shaft 102, and key transmission components such as the first active bevel gear 203, the first driven bevel gear 204, the second driven bevel gear 205, and the third driven bevel gear 206 are installed inside, so that these components are not directly exposed to the external environment. It can prevent dust, debris, moisture and other external factors from entering, reduce the erosion, wear and foreign matter interference of gears, shafts and other components, effectively extend the service life of each component, and ensure the stable and reliable operation of the entire transmission system.

[0066] Example 2 A method for producing an environmentally friendly asphalt mixture comprises the following steps: S1. Pre-treat the waste tires, separate the steel wires from the waste tires and cut them into blocks for later use; pre-treating the waste tires is to pave the way for their subsequent integration into asphalt mixtures as raw materials. Separate the steel wires to remove impurities, and cut them into blocks for easy storage, transportation, and subsequent placement and processing in production equipment, ensuring that the waste tire blocks can be evenly mixed with other raw materials.

[0067] S2. Quantitatively mix the raw materials of asphalt mixture for use, weigh 40% of waste tire blocks, 50% of asphalt raw materials, and 10% of chemical additives (chemical additives include activators and plasticizers, with activators accounting for 70% and plasticizers accounting for 30%); 40% of the waste tire blocks can provide certain special properties such as strength and elasticity, 50% of the asphalt raw materials are the main bonding component to ensure the bonding of the mixture, and 10% of the chemical additives play an auxiliary role in improving the performance of the mixture, accelerating the reaction, etc. The three are matched in proportion to provide a suitable raw material basis for subsequent reactions.

[0068] S3, start the production device, control the driving component 200 to rotate forward, continuously put the asphalt raw material and chemical additives into the second preparation component 500, and continuously put the waste tire blocks into the first preparation component 400; the asphalt raw material and chemical additives are put into the second preparation component 500, and the internal structure of the second preparation component 500 can be used to preheat the asphalt raw material and chemical additives by heat conduction; after the waste tire blocks are put into the first preparation component 400, the internal structure of the first preparation component 400 can be used to preheat the waste tire blocks, and the preheated waste tire blocks will enter the crushing component 300 for crushing, and finally enter the reactor 100 after crushing.

[0069] S4. Start the waste gas treatment device connected to the waste gas treatment component 600; use the waste gas treatment component 600 to collect and treat harmful gases volatilized from the raw materials during the production process to prevent environmental pollution.

[0070] S5. After the asphalt raw materials, chemical additives and waste tire blocks are added, the production device is allowed to continue to operate until the mixture is prepared. During this period, the stirring component 700 continues to stir under the drive tube 101 and the drive shaft 102, and the electric heating component 800 heats and maintains a suitable temperature, so that the waste tires, asphalt raw materials and chemical additives are fully mixed and a physical and chemical reaction occurs, forming an environmentally friendly asphalt mixture with excellent performance.

[0071] S6. Control the drive assembly 200 to rotate in the opposite direction, and the drive assembly 200 drives the discharging assembly 900 to discharge the prepared asphalt mixture for standby use; use the spiral blade 903 to push the finished mixture out of the discharging trough 901 and discharge it through the discharging pipe 904, completing the product collection.

[0072] S7. Turn off the exhaust gas treatment device and end the environmental protection process of this production.

[0073] The environmentally friendly asphalt mixture production method adopted in this application uses waste tires as the main raw material, which reduces the accumulation pollution of waste tires, converts waste into valuable building materials, realizes resource recycling and reuse, and conforms to the general trend of environmental protection. At the same time, the exhaust gas treatment device is fully operated to effectively purify the exhaust gas produced and reduce the pollution to the atmospheric environment, and the environmental protection concept is fully implemented from raw materials to the production process.

[0074] This application uses an integrated production device design to ensure that the raw material input, mixing, and discharging links are closely connected. The various components of the production device work in coordination, the crushing component crushes accurately, the stirring component stirs evenly, and the electric heating component controls the temperature accurately, so that the waste tire blocks, asphalt raw materials, and chemical additives are fully mixed and reacted, ensuring that the product has good strength, durability, anti-skid and other properties required for road paving, which is conducive to ensuring the quality of road projects.

[0075] The cost of waste tires used in this application is much lower than that of traditional high-quality aggregates, which is conducive to reducing the cost of raw material procurement. At the same time, the production device integrates multiple functions, reducing the purchase of additional equipment, and the energy-saving design such as heat recovery of the exhaust gas treatment component and thermal insulation of the electric heating component reduces energy consumption, reducing production costs from raw materials, equipment, and energy, and improving economic benefits.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
