[0002] RAP refers to recycled asphalt pavement material, which is an important material for achieving resource recycling in road engineering. During use, old asphalt pavement is recycled through milling, recycling and other methods to obtain waste asphalt mixture. This waste asphalt mixture contains old asphalt, gravel, sand and other materials, as well as possible residual additives. After recycling, it can be reused in asphalt pavement construction, which reduces costs and environmental burden. It is one of the core means of sustainable infrastructure construction.

[0003] In the RAP recycling process, heating and mixing the waste asphalt mixture is a crucial step, requiring heating and mixing equipment. Current technology commonly uses heated mixing tanks to heat and mix the waste asphalt mixture. In practice, the collected waste asphalt mixture is added to the tank for heating and mixing until completion. After the recycled asphalt mixture is poured out of the tank, the next round of heating and mixing begins. However, in this current technology, after each heating and mixing cycle, the acquired RAP must be discharged from the tank via a bottom discharge valve to completely empty the tank and remove any remaining material before proceeding to the next cycle. This process is inefficient and cumbersome. Utility Model Content

[0051] See Figures 1 to 7 The diagram shows a heating and stirring device for RAP regeneration according to the present invention. The device includes a base 1 and a first tank 2, the first tank 2 being fixedly mounted on the base 1. The device is characterized by further including: a stirring assembly 3, a heating assembly 4, and a second tank 5; the second tank 5 is detachably mounted in the first tank 2, and there is a gap between the second tank 5 and the first tank 2; the heating assembly 4 is disposed in the gap and is attached to the inner wall of the first tank 2; the stirring assembly 3 is movably mounted above the second tank 5 and partially extends into the second tank 5.

[0052] In this embodiment, a detachable second tank 5 is provided to hold the waste asphalt mixture to be processed. Heating is performed using a heating component 4, and stirring is performed using a stirring component 3. The first tank 2 is used to fix the second tank 5. After a batch of RAP recycled material has been heated and stirred, there is no need for time-consuming and laborious discharge operations via the bottom discharge valve, nor is there a need to clean the residual material inside the tank on-site. Instead, the second tank 5 can be directly removed and replaced as a whole. The processed material, along with the second tank 5, is removed for specialized unloading and cleaning. Simultaneously, another second tank 5 pre-loaded with new waste asphalt mixture to be processed is installed and heated and stirred. This significantly shortens the interval between processing cycles in the RAP recycling process, enabling the device to operate continuously and efficiently, fundamentally changing the material transfer method of traditional heating and stirring devices.

[0053] Furthermore, the heating component 4 is attached to the inner wall of the first tank 2, and an anti-wear sleeve is also provided on the heating component 4 to prevent it from being damaged by friction or impact during the removal or installation of the second tank 5. Furthermore, there may be a gap between the heating component 4 and the second tank 5, which is 3 mm to 10 mm.

[0054] Optionally, refer to Figure 2 The second tank 5 in this invention has either a limiting protrusion 51 or a limiting groove 52 on its outer wall, and the first tank 2 has the other of a limiting protrusion 51 or a limiting groove 52 on its inner wall. The limiting protrusion 51 is inserted into the limiting groove 52 to limit the second tank 5.

[0055] In this embodiment, the matching structure of the limiting protrusion 51 and the limiting groove 52 provides precise guidance for the rapid positioning of the second tank 5. During the replacement of the second tank 5, the operator can achieve precise alignment and installation without repeatedly adjusting the position, which greatly reduces the difficulty and time consumption of manual alignment. It effectively prevents the second tank 5 from being twisted under the action of the stirring component 3 during the stirring process, which would lead to a decrease in the stability of the device. Compared with the traditional flange bolt fixing method, this plug-in positioning significantly simplifies the operation process, making the replacement of the second tank 5 smoother and more efficient, further reducing the equipment standby time, and creating favorable conditions for continuous production.

[0056] Optionally, refer to Figure 2 In this utility model, at least two connectors 53 are provided inside the second tank body 5. The at least two connectors 53 are correspondingly provided on the inner wall of the second tank body 5 and are provided near the top of the second tank body 53.

[0057] In this embodiment, the connector 53 set on the inner wall of the second tank 5 forms a reliable force support point, which facilitates the grabbing operation of mechanized hoisting equipment. Through the quick docking of the connector 53 with the hoisting tool, the safe and efficient transfer of the second tank 5 is realized, avoiding the safety risks and efficiency limitations of manual handling. It is suitable for industrial production scenarios of large-scale RAP recycled materials, making the replacement process of the fully loaded second tank 5 more convenient and reliable, greatly reducing labor intensity, and significantly improving the equipment turnover efficiency in large-scale production.

[0058] Optionally, refer to Figure 1 , Figure 3 and Figure 4 The heating and stirring device for RAP regeneration in this utility model also includes a lifting assembly 6; the lifting assembly 6 is fixedly mounted on the base 1 and is located close to the outer wall of the first tank 2; the stirring assembly includes 3: a cover plate 31, a drive module 32, and a stirring module 33; wherein, the cover plate 31 is located above the second tank 5 and matches the opening of the second tank 5, and the cover plate 31 is fixedly connected to the movable end of the lifting assembly 6; the drive module 32 is fixedly mounted on the upper side of the cover plate 31; the stirring module 33 is movably mounted on the lower side of the cover plate 31, and partially extends through the cover plate 31 to connect with the drive module 32.

[0059] In this embodiment, the linkage design between the lifting component 6 and the cover plate 31 realizes the overall lifting function of the stirring component 3. When the second tank 5 needs to be replaced, the lifting component 6 raises the cover plate 31 to make room for the replacement of the second tank 5, allowing the hoisting equipment to enter the underside of the cover plate 31 to connect with the connector 53 inside the second tank 5, and lift and transfer the second tank 5, significantly shortening the preparation time and making the replacement operation of the second tank 5 smoother and more efficient. At the same time, the matching design between the cover plate 31 and the tank opening ensures the sealing performance in the working state, improving operating efficiency while ensuring that the production process is not affected by the outside world.

[0060] Furthermore, refer to Figure 8 The base 1 may include a fixed seat 11 and a movable seat 12. There are two fixed seats 11, which are disposed at both ends of the movable seat 12, and the movable seat 12 can move along the bearing ground. The first tank body 2 is fixedly disposed on the movable seat 12, and the lifting assembly 6 is disposed on the fixed seat 11.

[0061] In practical use, after the heating and mixing of a batch of RAP recycled material is completed, the cover plate 31 is first lifted by the lifting component 6 until the mixing module 33 under the cover plate is completely detached from the second tank 5. Then, the movable seat 12 is pulled to move the first tank 2 and the second tank 5 horizontally away from under the cover plate 31. At this time, the hoisting device is used to connect the connector 53 in the second tank 5 through the hook cable. The second tank 5 is lifted from the first tank 1 and transported to the next process, where the heated and mixed RAP recycled material is poured out. At the same time, the other second tank 5, which is filled with the new waste asphalt mixture to be processed, is hoisted into the first tank 1. The movable seat 12 is pushed so that the other second tank 5, which is filled with the new waste asphalt mixture to be processed, is under the cover plate 31. The lifting component 6 is lowered so that the cover plate 31 closes the opening of the second tank 5 and the mixing component 33 enters the second tank 5. The heating component 4 and the mixing component are started to carry out a new round of heating and mixing of RAP recycled material.

[0062] Furthermore, the movable seat 11 and the fixed seat 12 are provided with limit mechanisms to prevent the movable seat 11 and the fixed seat 12 from shifting or moving excessively due to difficulty in control during relative movement.

[0063] Optionally, refer to Figure 5 and Figure 6 The drive module 32 of this utility model includes a drive component 321 and a transmission box 322. The transmission box 322 is disposed on the upper side of the cover plate 31, and a first gear 323 and a second gear 324 are movably disposed in the transmission box 322. The drive component 321 is fixedly disposed on the upper side of the transmission box 322 and extends into the transmission box 322, and is connected to the first gear 323. The stirring module 33 includes a first stirring rod 331 and a second stirring rod 332. Both the first stirring rod 331 and the second stirring rod 332 partially extend through the cover plate 31. The first stirring rod 331 is connected to the first gear 323, and the second stirring rod 332 is connected to the second gear 324.

[0064] In this embodiment, the transmission structure of the first gear 323 and the second gear 324 in the transmission box 322 realizes the coordinated operation of the dual stirring rods driven by a single motor. The meshing design of the first gear 323 and the second gear 324 ensures the synchronous counter-rotation of the two stirring rods, forming a highly efficient convection stirring effect in the second tank 5. This design significantly expands the stirring coverage area, eliminates the mixing dead zones present in traditional single-shaft stirring, and enables the RAP recycled material to be more fully mixed, shortening the stirring time required to meet the process requirements. This indirectly improves the production capacity per unit time of the equipment and provides technical support for efficient continuous production.

[0065] Optionally, refer to Figure 5The second stirring rod 332 of this invention has a connecting cavity 333 arranged along the axial direction, and the connecting cavity 333 connects to the interior of the second tank 5; the heating and stirring device for RAP regeneration of this invention also includes a sampling component 7, which is arranged on the transmission box 322 and above the second gear 324; the sampling component 7 passes through the center of the second gear 324 and connects to the connecting cavity 333.

[0066] In this embodiment, the hollow second stirring rod 332 and the sampling component 7 are connected to realize the rapid sampling function in the production process. The material sample in the second tank 5 can be directly extracted through the connecting cavity 333 inside the second stirring rod 332 without interrupting production or opening the equipment. This allows the operator to monitor the reaction process in real time, accurately judge the best time to discharge the material, avoid the temperature fluctuations and production delays caused by traditional shutdown sampling, improve the controllability of the production process, and maximize the utilization rate of the equipment while ensuring product quality.

[0067] Optionally, refer to Figure 7 The sampling component 7 in this utility model includes a pump 71 and a sampling tube 72; the pump 71 is located above the second gear 324 and passes through the center of the second gear 324 to communicate with the communicating cavity 333; the sampling tube 72 is detachably connected to the pump 71.

[0068] In this embodiment, the detachable connection between the sampling pump 71 and the sampling tube 72 facilitates analysis after sampling, while ensuring the sealing reliability of the sampling system. This makes the sampling process simpler and faster, and operators can obtain samples from the second tank 5 for quality testing as needed, reducing the time consumption in the quality monitoring process and providing an effective technical means for the refined management of the production process.

[0069] Optionally, refer to Figure 2 The heating component 4 in this utility model includes multiple heating tubes 41, which are evenly arranged in the gaps.

[0070] In this embodiment, the heating tubes 41 evenly distributed in the gaps form a surrounding heating structure, which allows heat to be evenly conducted to the material through the second tank 5, improving heating efficiency. Uniform heating reduces the risk of material denaturation caused by uneven temperature, reduces scrap rate and rework probability, and ensures production efficiency.

[0071] Optionally, refer to Figure 7 The heating and stirring device for RAP regeneration in this utility model also includes a PLC component 8; at least one of the first stirring rod 331 and the second stirring rod 332 is provided with a temperature sensor 334; the temperature sensor 334, the heating tube 41 and the driving component 321 are all electrically connected to the PLC component 8.

[0072] In this embodiment, the temperature sensor 334 acquires the temperature status of the material in real time, and the PLC component 8 is used to adjust the heating power and stirring speed to ensure that the process parameters are always within the optimal range, which greatly improves the overall operating efficiency of the equipment.

[0073] In this application, PLC component 8 refers to a programmable logic controller. It should be noted that the selection of PLC components is a technical means well known to those skilled in the art, and therefore will not be described in detail here.

[0074] Optionally, refer to Figure 1 and Figure 7 The lifting assembly 6 in this utility model includes at least two lifting members 61, which are evenly arranged on the base 1, and the movable ends of the lifting members 61 are connected to the cover plate 31 through the fixing plate 62.

[0075] In this embodiment, the distributed lifting components 61 form a stable collaborative lifting mechanism through the fixed plate 62, ensuring the smoothness of the lifting process of the cover plate 31, preventing equipment damage caused by off-center loading, and improving the safety and reliability of the lifting operation.

[0076] Furthermore, the lifting component 61 in this embodiment can be selected as a hydraulic telescopic cylinder, a telescopic motor, or other lifting devices known to those skilled in the art, without further limitation.

[0077] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
