Description
Technical Field
[0001] This invention relates to the field of asphalt concrete waste recycling technology, specifically to a waste raw material recycling treatment device and its processing technology. Background Technology
[0002] Asphalt mixture recycling technology refers to the technology of recycling asphalt mixture pavement waste that cannot meet the requirements of use, mixing it with new aggregates, new asphalt, recycling agents and other materials, and then repaving the pavement. This technology achieves resource utilization by excavating, crushing and screening old materials, and using hot recycling or cold recycling processes.
[0003] For example, a mobile asphalt concrete waste recycling device, as disclosed in announcement number CN121407463A, relates to the field of asphalt concrete waste recycling technology. It includes: a base with a box on top, containing a storage tank; a fixed cylinder fixed to the top of the base, with a stirring assembly rotatably mounted inside; a power assembly located on top of the fixed cylinder, used to drive the stirring assembly; a return assembly located at the bottom of the fixed cylinder and connected to the box; and an asphalt conveying assembly mounted on the inner wall of the box. The asphalt conveying assembly, driven by the power assembly, simultaneously drives the stirring assembly, feeding asphalt from the storage tank into the stirring assembly to mix the asphalt and waste, thereby achieving the recycling of asphalt concrete waste.
[0004] The mixing of recycled asphalt concrete (RAP) involves multiple stages, including old material recycling, mix design, heating and temperature control, and mixing process. The mixing temperature is maintained between 160 and 180 degrees Celsius. Before mixing, it is necessary to remove the large particles remaining in the recycled material to reduce the reduction of the mixture density caused by excessively large particles, which can lead to uneven paving, difficulty in compaction, and consequently affect the smoothness and durability of the road surface. Furthermore, the aged asphalt inside the large particles is more difficult to be fully softened by the recycling agent. Screening out large particles helps to improve the subsequent mixing and recycling effect. Since recycled asphalt concrete contains aged asphalt binder, which has a certain degree of viscosity, conventional vibrating screens are difficult to screen completely and thoroughly, which can easily cause screen blockage. Summary of the Invention
[0005] The purpose of this invention is to provide a waste raw material recycling device and its processing technology to solve the problem that it is inconvenient to remove the large-diameter particles remaining in the recycled material, which reduces the density of the mixture, leading to uneven paving, difficulty in compaction, and thus affecting the smoothness and durability of the road surface.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a waste raw material recycling treatment device, comprising a placement plate and a bracket fixedly installed at the bottom of the placement plate, wherein a mixing cylinder is fixedly connected to one side of the top of the placement plate, and a pretreatment cylinder is installed on the top of the mixing cylinder; Also includes: The mixing cylinder is equipped with a regeneration component inside, and a feeding component is provided on the other side of the top of the placement plate. An annular cylinder is fixedly installed on the outside of the pretreatment cylinder, and a preheating cylinder is fixedly installed on the outside of the mixing cylinder. The regeneration assembly includes a square-hole screen plate fixedly installed inside the pretreatment cylinder. A vertical rod is rotatably installed on the top of the square-hole screen plate. Two push plates are fixedly connected to the outer side of the vertical rod. The outer side of the two push plates is fixedly connected to the same rotating ring. A sealing push plate is slidably installed on the inner ring of the rotating ring. A scraper is slidably installed on the bottom of the push plate.
[0007] Preferably, a servo motor is fixedly installed on one side of the bottom of the placement plate, and the output end of the servo motor is fixedly connected to a main shaft.

[0008] By adopting the above technical solution, the servo motor drives the spiral blades and also drives the rotating ring to rotate. The rotating ring drives the push plate to rotate and push, so that the recycled material on the top of the square hole screen plate will be spread out in a rotating manner. The scraper simultaneously scrapes the square hole screen plate intermittently and pushes the recycled material on the outer ring towards the middle, thereby fully disturbing and screening the recycled material to be screened.

A guide rod is slidably connected inside the square groove. A trapezoidal plate is fixedly connected to the top of the guide rod. The push rod abuts against the inclined surface of the trapezoidal plate.
[0012] By adopting the above technical solution, the push rod presses the inclined surface of the trapezoidal plate, causing the trapezoidal plate to descend. The trapezoidal plate compresses the second spring, which in turn drives the guide rod and scraper to descend, so that the scraper is in contact with the square hole screen plate for a period of time. The scraper then intermittently scrapes away debris from the square hole screen plate.
[0013] Preferably, a second spring is sleeved on the outer side of the guide rod, and the two ends of the second spring are fixedly connected to the trapezoidal plate and the scraper, respectively. A lower cover plate is fixedly installed on the top of the mixing cylinder, and the bottom of the connecting pipe is connected to the lower cover plate. A spiral blade is fixedly connected to the outer side of the main shaft, and a rotating component is also fixedly connected to the outer side of the main shaft. The rotating component is rotatably connected to the mixing cylinder.
[0014] By adopting the above technical solution, the main shaft will also drive the rotating parts to rotate, and the rotating parts will then drive the side plates and the fitting inclined plates to rotate, which facilitates the annular guidance of hot air inside the preheating cylinder.
[0015] Preferably, two side plates are fixedly connected in parallel to one side of the outer ring of the rotating component, and a side rod is fixedly connected between the two side plates. The interior of the preheating cylinder is provided with two upper and lower fitting inclined plates, and a connecting rod is fixedly connected between the two fitting inclined plates.

The top end of the spring three is fixedly connected to the upper side plate, and the bottom end of the spring three is fixedly connected to the lower fitting inclined plate. Two annular inclined rings are fixedly connected in parallel to the inner wall of the preheating cylinder, and the tops of the two fitting inclined plates abut against the tops of the two annular inclined rings respectively.
[0016] By adopting the above technical solution, due to the inclined ring setting of the annular inclined ring, the bonding inclined plate will also move back and forth, and the hot air will uniformly heat the outside of the mixing cylinder.
[0017] Preferably, the feeding assembly includes a support plate fixedly connected to the placement plate, a feeding box fixedly connected to the top of the support plate, a feed pipe fixedly connected to the top of the feeding box, an outer ring body fixedly installed on the outside of the feeding box, an electric heating coil fixedly installed inside the outer ring body, a fixing plate fixedly connected to the outside of the outer ring body, a hydraulic rod fixedly installed at the bottom of the fixing plate, an extrusion plate fixedly connected to the telescopic end of the hydraulic rod passing through the feeding box, the extrusion plate having the same longitudinal cross-sectional area as the inner wall of the feeding box, and a discharge pipe fixedly connected between the feeding box and the mixing cylinder.
[0018] By adopting the above technical solution, external asphalt is fed into the feeding box through the feed pipe, and asphalt is fed into the mixing cylinder through the discharge pipe. The hydraulic rod extends and drives the extrusion plate to move. The extrusion plate assists in pushing the asphalt, which facilitates the rapid and stable addition of asphalt.
[0019] Preferably, an air inlet pipe is fixedly connected to one side of the top of the annular cylinder, an air guide pipe is fixedly connected between the annular cylinder and the preheating cylinder, a pressure relief valve is fixedly installed on the upper outer side of the preheating cylinder, an air outlet pipe is fixedly connected to the lower outer side of the preheating cylinder, and a discharge pipe is fixedly installed at the bottom of the mixing cylinder, the discharge pipe passing through the placement plate and communicating with the outside.
[0020] By adopting the above technical solution, the external hot air duct is connected to the air inlet pipe, the hot air enters the annular cylinder, and then enters the preheating cylinder through the air guide pipe, and the discharge pipe facilitates material discharge.
[0021] The process for recycling raw waste materials involves the following steps: Step 1: The recycled material is fed into the pretreatment cylinder through the feeding pipe, and the external asphalt is fed into the feeding box through the feeding pipe. The external hot air pipe is connected to the air inlet pipe. The hot air enters the annular cylinder and then enters the preheating cylinder through the air guide pipe, thereby heating the pretreatment cylinder and the mixing cylinder. Step 2: Next, start the servo motor. The servo motor drives the main shaft and vertical rod to rotate. The main shaft drives the spiral blades to rotate, which facilitates the mixing process. The push plate rotates and spreads the recycled material on the square hole screen plate. The sealing push plate squeezes the recycled material on the outer ring towards the center. The scraper simultaneously scrapes the square hole screen plate intermittently to maintain the high efficiency of screening and feeding. Step 3: The main shaft will also drive the rotating parts to rotate, which in turn drives the side plates and the bonding inclined plates to rotate. Due to the inclined ring setting, the bonding inclined plates will also move back and forth, thereby maintaining the hot air to heat the outside of the mixing cylinder evenly and keeping the stirring temperature stable.
[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up a regeneration component, the regenerated material is fed into the pretreatment cylinder through the cooperation of components such as spiral blades, push plates, and rotating rings, and is screened through a square-hole screen plate. At the same time, the servo motor drives the spiral blades and also drives the rotating ring to rotate. The rotating ring drives the push plate to rotate and push, so that the regenerated material at the top of the square-hole screen plate is spread out in a rotating manner. The scraper simultaneously scrapes the square-hole screen plate intermittently and pushes the regenerated material in the outer ring towards the center, thereby fully agitating the regenerated material to be screened. This reduces the clogging of the square-hole screen plate by the large-diameter regenerated material at the bottom and facilitates the rapid screening and discharge of the small-diameter regenerated material at the top, maintaining high efficiency in screening and discharge. At the same time, it also slowly drives the inclined plate to rotate upwards, thereby maintaining uniform heating of the outside of the mixing cylinder by hot air, maintaining a stable stirring temperature, and improving the stirring and regeneration effect. The specific details are as follows: 1. By setting up a recycling component, the operator feeds recycled material into the pretreatment cylinder through the feeding pipe, and asphalt into the mixing cylinder through the feeding component. An external hot air pipe is connected to the air inlet pipe, and hot air enters the annular cylinder and then the preheating cylinder through the air guide pipe, thus heating the pretreatment and mixing cylinders. Next, the servo motor is started, driving the main shaft and vertical rod to rotate. The main shaft drives the spiral blades to rotate, facilitating mixing. The vertical rod drives the push plate and rotating ring to rotate. A distance is left between the bottom of the push plate and the square-hole screen plate to allow the push plate to spread the recycled material on the square-hole screen plate. The rotating ring drives the sliding rod and the arc plate to rotate, and the arc plate rotates to the position of the guide inclined plate. When the device is in place, it will move. The arc-shaped plate first slides onto the rotating ring, and after being in contact with the rotating ring for a period of time, it separates. The arc-shaped plate will drive the sliding rod to move, and the sliding rod will drive the sealing push plate to move. The sealing push plate stretches the first spring, and the sealing push plate will squeeze the recycled material on the outer ring towards the middle. The arc-shaped plate will also drive the push rod to slide, and the push rod will squeeze the inclined surface of the trapezoidal plate, causing the trapezoidal plate to descend. The trapezoidal plate compresses the second spring, and drives the guide rod and scraper to descend, so that the scraper is in contact with the square hole screen plate for a period of time. The scraper will simultaneously scrape the square hole screen plate intermittently, which can reduce the blockage of the square hole screen plate by the large-diameter recycled material below, and facilitate the rapid screening and discharge of the small-diameter recycled material above, maintaining the high efficiency of screening and discharge. 2. The main shaft will also drive the rotating parts to rotate, which in turn drives the side plates and the bonding inclined plates to rotate. Due to the inclined ring setting of the ring inclined ring, the bonding inclined plates will also move back and forth. The bonding inclined plates drive the connecting rod to move. When the lower bonding inclined plates rise, they will compress the third spring. When the bonding inclined plates fall, the third spring will rebound and reset, thereby maintaining the hot air to heat the outside of the mixing cylinder evenly, maintaining the stability of the mixing temperature, and improving the mixing and regeneration effect. 3. By setting up the feeding component, external asphalt is fed into the feeding box through the feeding pipe and into the mixing drum through the discharging pipe, which facilitates the subsequent heating and recycling of recycled materials. The inner part of the outer ring is equipped with an electric heating coil to keep the asphalt warm and reduce solidification during asphalt transportation. At the same time, the operator starts the hydraulic rod to work. The hydraulic rod extends and drives the extrusion plate to move. The extrusion plate assists in pushing the asphalt, which facilitates the rapid and stable addition of asphalt and facilitates subsequent reaction operations. Attached Figure Description

The air outlet pipe 12 is used to discharge the hot air inside the preheating cylinder 10 after processing.
[0029] like Figure 2 - Figure 11 As shown, the recycling assembly 5 includes a square-hole screen plate 53 fixedly installed inside the pretreatment cylinder 4. A vertical rod 57 is rotatably installed on the top of the square-hole screen plate 53. Two push plates 58 are fixedly connected to the outer side of the vertical rod 57.

A scraper 520 is slidably installed on the bottom of the push plate 58. The top of the rotating ring 59 is tightly fitted with the inner wall of the pretreatment cylinder 4 to prevent recycled material from falling into the position of the arc plate 511. When the sealing push plate 512 slides, it is tightly fitted with the square-hole screen plate 53 and the push plate 58 to prevent recycled material from entering the interior of the sealing push plate 512.

One end of the spring 513 is fixedly connected to the rotating ring 59. The other end of the spring 513 is fixedly connected to the sealing push plate 512, which facilitates the stable sliding of the sliding rod 510 and subsequent reset.
[0032] The inner wall of the pretreatment cylinder 4 is symmetrically and fixedly connected with guide inclined plates 514, and there are no less than three guide inclined plates 514. A push rod 515 is fixedly connected to the side of the arc plate 511 near the rotating ring 59. The push rod 515 is slidably connected to the push plate 58. A square groove 516 is opened inside the push plate 58. A guide rod 517 is slidably connected inside the square groove 516. A trapezoidal plate 518 is fixedly connected to the top of the guide rod 517. The push rod 515 abuts against the inclined surface of the trapezoidal plate 518, so that when the push rod 515 squeezes the trapezoidal plate 518, it will drive the guide rod 517 and the scraper 520 to descend.
[0033] A second spring 519 is sleeved on the outside of the guide rod 517. The two ends of the second spring 519 are fixedly connected to the trapezoidal plate 518 and the scraper 520, respectively. A lower cover plate 521 is fixedly installed on the top of the mixing cylinder 3. The bottom of the connecting pipe 56 is connected to the lower cover plate 521. A spiral blade 522 is fixedly connected to the outside of the main shaft 52. A rotating component 523 is also fixedly connected to the outside of the main shaft 52. The rotating component 523 is rotatably connected to the mixing cylinder 3. The spiral blade 522 is used for mixing and treating the internal recycled material and asphalt.
[0034] Two side plates 524 are fixedly connected in parallel to one side of the outer ring of the rotating component 523. A side rod 525 is fixedly connected between the two side plates 524. The interior of the preheating cylinder 10 is provided with two upper and lower fitting inclined plates 526. A connecting rod 527 is fixedly connected between the two fitting inclined plates 526. The lower fitting inclined plate 526 is slidably connected to the side rod 525. A spring 3 528 is sleeved on the outside of the side rod 525. The top end of the spring 3 528 is fixedly connected to the upper side plate 524, and the bottom end of the spring 3 528 is fixedly connected to the lower fitting inclined plate 526. Two annular inclined rings 529 are fixedly connected in parallel to the inner wall of the preheating cylinder 10. The tops of the two fitting inclined plates 526 and the two annular inclined rings 529 respectively abut against each other.
[0035] Damping blocks are installed at both ends of spring 1 (513), spring 2 (519), and spring 3 (528) to reduce reciprocating vibration and maintain stable telescopic use.
[0036] Example 1: As Figure 2 - Figure 11 As shown, the operator feeds the recycled material into the pretreatment cylinder 4 through the feeding pipe 55, and the asphalt into the mixing cylinder 3 through the feeding assembly 6. The external hot air pipe is connected to the air inlet pipe 8, and the hot air enters the annular cylinder 7 and then enters the preheating cylinder 10 through the air guide pipe 9, thereby heating the pretreatment cylinder 4 and the mixing cylinder 3. Then, the servo motor 51 is started to work. The servo motor 51 drives the main shaft 52 and the vertical rod 57 to rotate. The main shaft 52 drives the spiral blade 522 to rotate, which facilitates the mixing process.
[0037] The vertical rod 57 drives the push plate 58 and the rotating ring 59 to rotate. A distance is left between the bottom end of the push plate 58 and the square hole screen plate 53 to facilitate the rotation and spreading of the recycled material on the square hole screen plate 53. The rotating ring 59 drives the slide rod 510 and the arc plate 511 to rotate. When the arc plate 511 rotates to the position of the guide inclined plate 514, it will move. The arc plate 511 first slides onto the rotating ring 59, and after being in contact with the rotating ring 59 for a period of time, it separates. The arc plate 511 will drive the slide rod 510 to move. The slide rod 510 drives the sealing push plate 512 to move. The sealing push plate 512 stretches the spring 513 and squeezes the recycled material on the outer ring towards the middle.
[0038] The arc plate 511 also drives the push rod 515 to slide. The push rod 515 presses the inclined surface of the trapezoidal plate 518, causing the trapezoidal plate 518 to descend. The trapezoidal plate 518 compresses the second spring 519, which in turn drives the guide rod 517 and the scraper 520 to descend, so that the scraper 520 is in contact with the square hole screen plate 53 for a period of time. This allows the scraper 520 to intermittently scrape the square hole screen plate 53 in sync, which can reduce the blockage of the large-diameter recycled material below on the square hole screen plate 53, and facilitate the rapid screening and discharge of the small-diameter recycled material above, thus maintaining the high efficiency of screening and discharge.
[0039] The main shaft 52 also drives the rotating component 523 to rotate, which in turn drives the side plate 524 and the bonding inclined plate 526 to rotate. Due to the inclined ring setting of the annular inclined ring 529, the bonding inclined plate 526 will also move up and down reciprocally. The bonding inclined plate 526 drives the connecting rod 527 to move. When the lower bonding inclined plate 526 rises, it will compress the spring 3 528. When the bonding inclined plate 526 falls, the spring 3 528 will rebound and reset, thereby maintaining the hot air to uniformly heat the outside of the mixing cylinder 3, maintaining the stability of the stirring temperature, and improving the stirring and regeneration effect.
[0040] like Figure 2 and Figure 12 - Figure 13 As shown, a feeding assembly 6 is provided on the other side of the top of the placement plate 1. The feeding assembly 6 includes a support plate 61 fixedly connected to the placement plate 1. A feeding box 62 is fixedly connected to the top of the support plate 61. A feed pipe 63 is fixedly connected to the top of the feeding box 62. An outer ring body 64 is fixedly installed on the outside of the feeding box 62. An electric heating coil is fixedly installed inside the outer ring body 64 to facilitate heating and heat preservation of the asphalt.
[0041] A fixing plate 65 is fixedly connected to the outer side of the outer ring body 64. A hydraulic rod 66 is fixedly installed at the bottom of the fixing plate 65. The telescopic end of the hydraulic rod 66 passes through the feeding box 62 and is fixedly connected to an extrusion plate 67. The extrusion plate 67 has the same longitudinal cross-sectional area as the inner wall of the feeding box 62. A discharge pipe 68 is fixedly connected between the feeding box 62 and the mixing cylinder 3.
[0042] Example 2: Figure 12 - Figure 13 As shown, external asphalt is fed into the feeding box 62 through the feed pipe 63, and the asphalt is fed into the mixing drum 3 through the discharge pipe 68, which facilitates the subsequent heating and recycling of recycled materials. An electric heating coil is installed inside the outer ring body 64 to keep the asphalt warm and reduce solidification during asphalt transportation. At the same time, the operator starts the hydraulic rod 66 to work. The hydraulic rod 66 extends and drives the extrusion plate 67 to move. The extrusion plate 67 assists in pushing the asphalt, which facilitates the rapid and stable addition of asphalt and facilitates subsequent reaction operations.
[0043] Working principle: When using this device, firstly, as... Figure 1 - Figure 13 As shown, the operator feeds recycled material into the pretreatment cylinder 4 through the feeding pipe 55, and external asphalt into the feeding box 62 through the feeding pipe 63. The external hot air pipe is connected to the air inlet pipe 8, and the hot air enters the annular cylinder 7 and then enters the preheating cylinder 10 through the air guide pipe 9, thereby heating the pretreatment cylinder 4 and the mixing cylinder 3. Then, the servo motor 51 is started, which drives the main shaft 52 and the vertical rod 57 to rotate. The main shaft 52 drives the spiral blades 522 to rotate, which facilitates the mixing process. The pushing plate 58 rotates and spreads the recycled material on the square hole screen plate 53. The sealing push plate 512 squeezes the recycled material on the outer ring towards the middle, and the arc plate 511 also drives the push rod 515 to slide. The push rod 515 squeezes the inclined surface of the trapezoidal plate 518, causing the trapezoidal plate 518 to descend. 518 compresses the second spring 519, which in turn drives the guide rod 517 and scraper 520 to descend, causing the scraper 520 to adhere to the square hole screen plate 53 for a period of time. This allows the scraper 520 to synchronously scrape the square hole screen plate 53 intermittently, maintaining efficient screening and feeding. The main shaft 52 also drives the rotating part 523 to rotate, which in turn drives the side plate 524 and the contacting inclined plate 526 to rotate. Due to the inclined ring setting of the annular inclined ring 529, the contacting inclined plate 526 will also move back and forth. The contacting inclined plate 526 drives the connecting rod 527 to move. When the lower contacting inclined plate 526 rises, it will compress the third spring 528. When the contacting inclined plate 526 descends, the third spring 528 will rebound and reset, thereby maintaining uniform heating of the outside of the mixing cylinder 3 by hot air and maintaining a stable stirring temperature.
