Description

Technical Field

[0001] The present application relates to the field of road construction machinery, and in particular to a continuous asphalt plant hot recycled mixture mixing station. Background Art

[0002] Factory-mixed hot recycling means that the old asphalt pavement is excavated and transported back to the mixing station, and then crushed centrally. According to the quality requirements of different levels of the pavement, the mix design is carried out to determine the addition ratio of the old asphalt mixture. The regeneration agent, new asphalt material, new aggregate, etc. are re-mixed into a new mixture in a mixer in a certain proportion, thereby obtaining excellent recycled asphalt concrete and paving it into a recycled asphalt pavement.

[0003] The production of asphalt recycled materials needs to be carried out in a mixing station. When mixing hot recycled materials in the factory, the old materials processed by the crushing and screening system need to be transported to the waste heat regeneration drying drum through the supply system and the lifting system for drying and solidification. The old materials after drying and solidification are transported to the storage tank by the conveying system for storage. Since the bonding problem of recycled materials is a derivative problem of the hot recycling technology of factory-mixed asphalt, the bonding problem restricts the entire production process from the moment the temperature of the recycled materials is increased. Whether in the drying drum, or in the temporary storage unit, recycled material metering unit, chute, etc., the bonding problem is everywhere. On the one hand, bonding is related to the inherent physical properties of asphalt recycled materials, and on the other hand, it is closely related to its heating temperature. Therefore, before storing the asphalt recycled materials, it is necessary to spray anti-adhesive agent on the asphalt recycled materials and keep the asphalt recycled materials at a constant temperature.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the following defects exist: when transporting asphalt recycled materials to the storage tank, a belt line is often used for transportation, and the asphalt recycled materials are accumulated on the belt line and transported to the storage tank via the belt line. In the process of transporting the asphalt recycled materials, an anti-adhesive agent is sprayed on the asphalt recycled materials on the belt line. Due to the poor fluidity of the anti-adhesive agent, less anti-adhesive agent is attached to the asphalt recycled materials at the bottom of the belt line, which causes part of the asphalt recycled materials to adhere to the belt line, and also causes the asphalt recycled materials particles entering the storage tank to adhere to each other. Summary of the invention

[0005] In order to improve the problem of adhesion of asphalt recycled materials, the present application provides a continuous asphalt plant mixing hot recycled mixture mixing station.

[0006] The present application provides a continuous asphalt plant hot recycled mixture mixing station adopts the following technical solution:

[0007] A continuous asphalt plant hot recycled mixture mixing station, including a screening and crushing system, a supply system, a lifting system, a regeneration drying drum, a conveying system and a storage tank. A feed port is provided on the top of the storage tank, and a carrying plate is also provided on the top of the storage tank. The asphalt recycled material is transported to the carrying plate through the conveying system. A drop hole is provided at one end of the carrying plate close to the storage tank, and a discharge plate is provided on the carrying plate at the drop hole. The end of the discharge plate away from the carrying plate is movably aligned with the feed port, a storage cylinder for storing an anti-sticking agent is provided on the carrying plate, and a mixing device for mixing the anti-sticking agent with the asphalt recycled material is also provided on the carrying plate.

[0008] By adopting the above technical scheme, the asphalt regeneration material is crushed and screened through the screening and crushing system, and then transmitted to the regeneration drying drum through the supply system and the lifting system for drying and solidification. The dried and solidified asphalt regeneration material is transmitted to the storage tank through the conveying system. The conveying system transmits the asphalt regeneration material to the carrier plate, and the anti-adhesive agent in the storage cylinder is transported to the carrier plate. At the same time, the mixing device is started, and the mixing device stirs and mixes the asphalt regeneration material and the anti-adhesive agent, so that the anti-adhesive agent is fully attached to the asphalt regeneration material particles as much as possible, effectively reducing the viscosity between the asphalt regeneration material particles, and improving the bonding problem of the asphalt regeneration material. The mixed asphalt regeneration material enters the discharge plate through the drop hole, and is transmitted through the discharge plate toward the storage tank, so that the asphalt regeneration material enters the storage tank through the feed port for storage. Because the asphalt regeneration material particles are in more sufficient contact with the anti-adhesive agent under the action of the mixing device, the bonding problem of the asphalt regeneration material in the storage tank is improved.

[0009] Optionally, the supporting plate is cone-shaped, and the tip of the supporting plate is arranged to face away from the storage tank. The mixing device includes a liquid supply component for conveying the anti-sticking agent in the storage cylinder to the supporting plate, a threaded ring rotating on the supporting plate, and a driving component for driving the threaded ring to rotate. The threaded ring is slidingly fitted with the arc circumferential wall of the supporting plate, and the driving component is located at the end of the threaded ring away from the storage tank.

[0010] By adopting the above technical solution, the liquid supply component transports the anti-adhesive agent in the storage cylinder to the carrier plate, and the asphalt regeneration material is transported to the carrier plate. The driving component is started, and the driving component drives the thread ring to rotate on the carrier plate. Since the thread ring and the arc circumferential wall of the carrier plate slide and fit, the asphalt regeneration material is stirred under the action of the rotating thread ring, so that the asphalt regeneration material is fully contacted with the anti-adhesive agent as much as possible, thereby improving the adhesion problem of the asphalt regeneration material. Since the carrier plate is conical, the asphalt regeneration material on the carrier plate is stirred and transferred to the storage tank under the drive of the rotating thread ring, thereby completing the unloading process of the asphalt regeneration material.

[0011] Optionally, the liquid supply assembly includes an infusion tube fixedly connected to the threaded ring and an injection head connected to the infusion tube, the infusion tube is arranged along the bending direction of the threaded ring, a plurality of overflow holes are opened on the infusion tube, an injection head is connected to the storage cylinder, the injection head is movably docked with the injection head, a valve is provided on the injection head, and a control component for opening and closing the valve is provided on the injection head.

[0012] By adopting the above technical solution, since the driving assembly drives the threaded ring to rotate, the threaded ring drives the injection head to rotate through the infusion tube. When the injection head rotates to just below the injection head, the control component drives the valve to open, and the anti-sticking agent in the storage cylinder flows into the infusion tube through the injection head and the infusion head. The anti-sticking agent in the infusion tube overflows onto the carrier plate through multiple overflow holes. When the rotating threaded ring stirs the asphalt recycled material on the carrier plate, the anti-sticking agent can fully contact with the asphalt recycled material particles, thereby improving the bonding problem of the asphalt recycled material.

[0013] Optionally, one end of the thread ring away from the storage tank is located at the tip of the supporting plate, and the driving assembly includes a rotating rod rotatably arranged at the tip of the supporting plate and a driving member for driving the rotating rod to rotate, the central axis of the rotating rod is colinearly arranged with the central axis of the supporting plate, the end of the thread ring away from the storage tank is fixedly connected to the rotating rod, and the filling head is located on the side of the driving member away from the storage cylinder.

[0014] By adopting the above technical solution, when the asphalt recycled material needs to be stirred, the driving member is started, and the driving member drives the rotating rod to rotate. Since the rotating rod is located at the tip of the carrier plate and the rotating rod and the central axis of the carrier plate are arranged in a colinear manner, the thread ring connected to the rotating rod can rotate synchronously with the rotating rod, thereby achieving the stirring effect of the asphalt recycled material on the carrier plate. Since the injection head needs to rotate synchronously with the thread ring, the injection head is located on the side of the driving member away from the storage cylinder, so that the rotation of the injection head and the thread ring is not interfered by the driving member.

[0015] Optionally, a cover shell is provided around the supporting plate, and the side of the threaded ring away from the supporting plate is slidingly fitted with the inner wall of the cover shell. One end of the cover shell close to the storage tank is sealed with the supporting plate, and the other end is provided with a feed barrel. The end of the feed barrel away from the cover shell is open, and the discharge port of the conveying system is connected to the opening of the feed barrel.

[0016] By adopting the above technical scheme, the asphalt recycled material is transported to the feed barrel via the conveying system, and the asphalt recycled material enters the cover shell via the feed barrel. Since the two sides of the thread ring are respectively slidably fitted with the inner wall of the cover shell and the supporting plate, the rotating thread ring can fully stir the asphalt recycled material, so as to fully contact the anti-sticking agent with the asphalt recycled material particles, thereby achieving the purpose of improving the adhesion problem of the asphalt recycled material.

[0017] Optionally, a plurality of storage tanks are provided, and the plurality of storage tanks are arranged around the circumference of the supporting plate, and a rotating component for driving the supporting plate to rotate is provided between the plurality of storage tanks.

[0018] By adopting the above technical solution, multiple storage tanks can store different types of asphalt recycled materials, and the rotating component can drive the carrying plate to rotate, so as to realize automatic switching of the unloading plate between different storage tanks, so as to facilitate the transmission and storage of different types of asphalt recycled materials.

[0019] Optionally, a connecting plate is provided on the carrying plate at the drop hole, the unloading plate is rotatably provided on the connecting plate at one end away from the storage tank, convex strips are provided on both sides of the feed port on the storage tank, a guide surface is provided at one end of the convex strip close to the feed port, and the unloading plate is movably abutted against the convex strip;

[0020] When the stripper plate abuts against the end surface of the convex strip away from the storage tank, the end of the stripper plate away from the connecting plate is higher than the end of the stripper plate close to the connecting plate;

[0021] When one end of the stripping plate away from the connecting plate is located at the feed port, one end of the stripping plate close to the connecting plate is higher than one end of the stripping plate away from the connecting plate.

[0022] By adopting the above technical solution, when the rotating assembly drives the carrier plate to rotate, the carrier plate drives the connecting plate to rotate, and the connecting plate drives the discharge plate to rotate. When the discharge plate rotates to align with the feed port, the end of the discharge plate away from the connecting plate tilts downward to point to the feed port, and at this time, the asphalt recycled material on the carrier plate falls into the storage tank through the drop hole, the discharge plate and the feed port in sequence.

[0023] When the asphalt recycled material on the carrier plate needs to be stored in other storage tanks, it is only necessary to drive the carrier plate to rotate through the rotating assembly, and the carrier plate drives the discharge plate to rotate through the connecting plate. The end of the discharge plate away from the connecting plate rotates in the direction away from the storage tank under the drive of the convex guide surface, so that the end of the discharge plate away from the connecting plate slides and presses against the end surface of the convex strip away from the storage tank. At this time, the end of the discharge plate away from the connecting plate is tilted upward, so that during the rotation of the carrier plate, the asphalt recycled material retained on the discharge plate is prevented from spilling onto the top wall of the storage tank as much as possible.

[0024] Optionally, a door panel is provided on the storage tank at the feed port for opening and closing, and a control module for controlling the opening and closing of the door panel is provided on the convex strip.

[0025] By adopting the above technical solution, the control module can open and close the feed port by controlling the door panel, so that when there is no need to feed materials into the storage tank, the storage tank is a closed chamber, ensuring a stable storage environment for the asphalt recycled material.

[0026] Optionally, a temperature control system is provided in the storage tank, and a heat-insulating layer is provided on the peripheral wall of the storage tank.

[0027] By adopting the above technical solution, the temperature control system can control the temperature in the storage tank so that the temperature in the storage tank is maintained within the set temperature range, thereby ensuring the quality of the asphalt recycled material in the storage tank. At the same time, the setting of the insulation layer can reduce the heat loss in the storage tank, which can not only achieve the effect of energy saving and environmental protection, but also assist the temperature control system in maintaining the stability of the temperature in the storage tank.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The asphalt recycled material is transported to the carrier plate through the conveying system, and the anti-sticking agent in the storage cylinder is transported to the carrier plate. The asphalt recycled material is stirred by the rotating thread ring, so that the asphalt recycled material is in full contact with the anti-sticking agent as much as possible, improving the bonding problem of the asphalt recycled material;

[0030] 2. The asphalt recycled material is transported to the feed barrel through the conveying system, and then enters the housing through the feed barrel. Since the two sides of the thread ring are respectively slidably fitted with the inner wall of the housing and the carrier plate, the rotating thread ring can fully stir the asphalt recycled material, so as to fully contact the anti-adhesive agent with the asphalt recycled material particles, thereby achieving the purpose of improving the adhesion problem of the asphalt recycled material;

[0031] 3.

[0038] The following is combined with Figure 1-5 This application is described in further detail.

[0039] The present application embodiment discloses a continuous asphalt plant hot recycled mixture mixing station. Figure 1 and Figure 2 The continuous asphalt plant hot-mixed recycled mixture mixing station includes a screening and crushing system 1, a lifting system 2, a regeneration drying drum 3, a conveying system 4 and a storage tank 5. The asphalt regeneration material is crushed and screened by the screening and crushing system 1, and then transmitted to the regeneration drying drum 3 through the lifting system 2 for drying and solidification. The dried and solidified asphalt regeneration material is transmitted to the storage tank 5 through the conveying system 4 and stored in the storage tank 5. Since different types of asphalt regeneration materials need to be stored separately, multiple storage tanks 5 are provided, and the cross-section of the storage tank 5 is fan-shaped, and multiple storage tanks 5 are enclosed to form a ring shape.

[0040] Reference Figure 2 and Figure 3A compass-shaped bracket is arranged between the multiple storage tanks 5. The multiple storage tanks 5 are fixed to the bracket by screws. The bracket connects the multiple storage tanks 5 to form a stable ring. A bearing plate 7 is arranged on the top of the storage tank 5. The bearing plate 7 is conical, and the tip of the bearing plate 7 is arranged in a direction away from the storage tank 5. The bearing plate 7 is located in the middle of the ring formed by the multiple storage tanks 5. The bearing plate 7 is installed on the bracket, and the multiple storage tanks 5 are arranged around the bearing plate 7.

[0041] Reference Figure 2 and Figure 3 The side of the carrier plate 7 is surrounded by a cover 16, which is in the shape of a trumpet. One end of the cover 16 close to the storage tank 5 is sealed with the carrier plate 7, and the other end is provided with a feed barrel 17, which is integrally formed with the cover 16 and coaxially arranged with the carrier plate 7. The end of the feed barrel 17 away from the cover 16 is open, and the discharge port of the conveying system 4 is connected to the opening of the feed barrel 17. In order to facilitate the conveying system 4 to quickly transfer the asphalt recycled material to the feed barrel 17, the end of the feed barrel 17 away from the cover 16 is integrally formed with a trumpet, and the small-diameter end of the trumpet is connected to the feed barrel 17.

[0042] In order to prevent the asphalt recycled material falling into the storage tank 5 from sticking together as much as possible, refer to Figure 3 and Figure 4 A storage cylinder 10 for storing anti-adhesive agent is provided on the carrier plate 7, and the storage cylinder 10 is located on the side of the carrier plate 7 away from the storage tank 5. An inner casing 26 is fixedly sleeved on the outer periphery of the storage tank 5 by screws, and the inner casing 26 is coaxially arranged with the feed cylinder 17, and the inner casing 26 is located inside the feed cylinder 17. A gap is provided between the inner casing 26 and the feed cylinder 17 for the asphalt recycled material to pass through. A support rod for fixing the outer peripheral wall of the inner casing 26 and the inner wall of the feed cylinder 17 is fixedly connected by screws.

[0043] Reference Figure 3 and Figure 4 , a mixing device for mixing the anti-adhesive agent with the asphalt recycled material is also provided on the carrier plate 7. A drop hole 8 is provided at one end of the carrier plate 7 close to the storage tank 5, a discharge plate 9 is provided at the drop hole 8 on the carrier plate 7, a feed port 6 is also provided on the top of the storage tank 5, and an end of the discharge plate 9 away from the carrier plate 7 is movably aligned with the feed port 6. The mixed asphalt recycled material on the carrier plate 7 is transferred to the storage tank 5 through the drop hole 8, the discharge plate 9 and the feed port 6 in sequence for storage.

[0044] Reference Figure 3 and Figure 5The mixing device includes a liquid supply component 11 for conveying the anti-sticking agent in the storage cylinder 10 to the carrier plate 7, a threaded ring 12 rotatably arranged on the carrier plate 7, and a driving component 13 for driving the threaded ring 12 to rotate. One side of the threaded ring 12 is slidably fitted with the arc circumferential wall of the carrier plate 7, and the other side is slidably fitted with the inner wall of the cover 16. The end of the threaded ring 12 away from the storage tank 5 is located at the tip of the carrier plate 7, and the end close to the storage tank 5 is located at the drop hole 8. The driving component 13 is located at the end of the threaded ring 12 away from the storage tank 5.

[0045] The liquid supply component 11 delivers the anti-adhesive agent in the storage cylinder 10 to the carrier plate 7, and the asphalt regeneration material is delivered to the carrier plate 7. The drive component 13 is started, and the drive component 13 drives the thread ring 12 to rotate on the carrier plate 7. Since one side of the thread ring 12 is slidingly fitted with the arc circumferential wall of the carrier plate 7 and the other side is slidingly fitted with the inner wall of the cover 16, the asphalt regeneration material is stirred under the action of the rotating thread ring 12, so that the asphalt regeneration material is in full contact with the anti-adhesive agent as much as possible, improving the bonding problem of the asphalt regeneration material. Because the carrier plate 7 is conical, the rotating thread ring 12 can also push the asphalt regeneration material between the cover 16 and the carrier plate 7 to move toward the drop hole 8, and the mixed asphalt regeneration material can be discharged from the carrier plate 7 through the drop hole 8.

[0046] In order to achieve the stable rotation of the thread ring 12, refer to Figure 3 and Figure 5 The driving assembly 13 includes a rotating rod 131 rotatably connected to the tip of the carrier plate 7 through a rotating bearing and a driving member 132 for driving the rotating rod 131 to rotate. The central axis of the rotating rod 131 is arranged colinearly with the central axis of the carrier plate 7. The end of the rotating rod 131 away from the carrier plate 7 is rotatably connected to the bottom wall of the storage tube 10, and the end of the threaded ring 12 away from the storage tank 5 is fixedly connected to the rotating rod 131. In the embodiment of the present application, the driving member 132 includes a driven bevel gear coaxially fixed to the rotating rod 131, a driving bevel gear meshing with the driven bevel gear, and a motor for driving the driving bevel gear to rotate. The motor is fixedly connected to the outer wall of the feed barrel 17 by screws, and the output shaft of the motor passes through the barrel walls of the feed barrel 17 and the inner casing 26 and is coaxially fixedly connected to the driving bevel gear. The motor drives the active bevel gear to rotate, and the active bevel gear drives the rotating rod 131 to rotate through the driven bevel gear. The rotating rotating rod 131 drives the threaded ring 12 to rotate and stir between the carrier plate 7 and the cover 16, thereby achieving the mixing and transmission of the asphalt recycled material. In other embodiments, any structure that can drive the rotating rod 131 to rotate is acceptable.

[0047] In order to achieve full mixing of asphalt recycled materials, refer to Figure 3 and Figure 5The liquid supply assembly 11 includes an infusion tube 111 fixedly connected to the threaded ring 12 and an injection head 112 connected to the infusion tube 111. The infusion tube 111 is arranged along the bending direction of the threaded ring 12. A plurality of overflow holes are provided on the infusion tube 111, and the plurality of overflow holes are arranged at intervals along the extension direction of the infusion tube 111. In order to realize the automatic delivery of the anti-adhesive agent into the infusion tube 111, an injection head 14 is connected to the storage tube 10. The injection head 14 is located on the end surface of the storage tube 10 close to the carrier plate 7, and the injection head 14 is located in the inner casing 26. One end of the injection head 14 is connected to the storage tube 10, and the other end is located above the injection head 112 and is movably connected to the injection head 112. A valve 15 for controlling the on and off of the injection head 14 is provided on the injection head 14.

[0048] Reference Figure 3 and Figure 5 The injection head 112 is connected to the liquid delivery tube 111 through a branch pipe, and the branch pipe is arranged in parallel with the rotating rod 131. One end of the branch pipe connected to the injection head 112 is located in the inner casing 26, so as to prevent the asphalt recycled material falling into the feed barrel 17 from entering the injection head 112 as much as possible. When the driving member 132 drives the thread ring 12 to rotate, the thread ring 12 drives the injection head 112 to rotate synchronously through the liquid delivery tube 111 and the branch pipe. In order to avoid interference between the injection head 112 and the driving member 132 during rotation, the injection head 112 is located on the side of the driving member 132 away from the storage barrel 10. In order to realize automatic delivery of the anti-adhesive agent to the injection head 112, a control member for opening and closing the valve 15 is provided on the injection head 112. The control member is an induction ring disposed on the end surface of the injection head 112 away from the branch pipe. When the induction ring senses that the injection head 112 is aligned with the injection head 14, the induction ring drives the valve 15 to open through the processing system, so that the anti-adhesion agent in the storage cylinder 10 flows into the injection head 112 through the injection head 14. When the induction ring senses that the injection head 112 is no longer aligned with the injection head 14, the induction ring drives the valve 15 to close through the processing system, thereby reducing the loss of the anti-adhesion agent.

[0049] When the conveying system 4 transfers the asphalt regeneration material toward the storage tank 5, the asphalt regeneration material falls from the gap between the feed barrel 17 and the inner casing 26 onto the carrier plate 7. At this time, the driving member 132 is started, and the driving member 132 drives the threaded ring 12 to rotate. The rotating threaded ring 12 stirs and transfers the asphalt regeneration material on the carrier plate 7. When the threaded ring 12 drives the injection head 112 to rotate to align with the injection head 14, the anti-sticking agent in the storage barrel 10 is poured into the liquid infusion pipe 111. The anti-sticking agent in the liquid infusion pipe 111 overflows onto the carrier plate 7 through multiple overflow holes. When the rotating threaded ring 12 stirs the asphalt regeneration material on the carrier plate 7, the anti-sticking agent can fully contact with the asphalt regeneration material particles, thereby improving the bonding problem of the asphalt regeneration material. The asphalt regeneration material after mixing moves towards the discharge hole 8 under the push of the threaded ring 12, and the asphalt regeneration material after mixing is transferred to the storage tank 5 through the discharge hole 8, the discharge plate 9 and the feed port 6 in sequence for storage.

[0050] When it is necessary to switch different storage tanks to store asphalt recycled materials, the carrier plate 7 can be driven to rotate, so refer to Figure 3 and Figure 4 A rotating assembly 18 for driving the carrier plate 7 to rotate is arranged between the plurality of storage tanks 5. The rotating assembly 18 comprises a support tube and a driving motor. The support tube is located between the bracket and the carrier plate 7. One end of the support tube is fixedly connected to the bracket and the other end is rotatably connected to the carrier plate 7 through a rotating bearing. The support tube and the carrier plate 7 are arranged coaxially, and the support tube rotatably supports the carrier plate 7 on the bracket. The driving motor is fixedly connected to the end face of the bracket away from the carrier plate 7 by screws, and the output shaft of the driving motor rotatably passes through the bracket and is coaxially fixedly connected to the carrier plate 7 by screws.

[0051] Reference Figure 3 and Figure 4 A connecting plate 19 is provided on the carrier plate 7 at the blanking hole 8, and the connecting plate 19 is vertically fixed to the bottom wall of the carrier plate 7. A rotating bar 27 is fixed to the connecting plate 19 by screws, and the end of the rotating bar 27 away from the connecting plate 19 is tilted downward. The cross section of the rotating bar 27 is in an arc shape, and the material of the rotating bar 27 can be rubber material or spring steel material. In the embodiment of the present application, the material of the rotating bar 27 is spring steel material.

[0052] Reference Figure 3 and Figure 4, the end of the unloading plate 9 away from the storage tank 5 is fixedly connected to the end of the rotating bar 27 away from the connecting plate 19, and the cross section of the unloading plate 9 is also arc-shaped. The unloading plate 9 is rotatably connected to the connecting plate 19 through the rotating bar 27. When the end of the unloading plate 9 away from the rotating bar 27 is aligned with the feed port 6 on the storage tank 5, the end of the unloading plate 9 close to the connecting plate 19 is higher than the end of the unloading plate 9 away from the connecting plate 19, and the asphalt recycled material on the carrying plate 7 can slide to the feed port 6 through the rotating bar 27 and the unloading plate 9, and enter the storage tank 5 through the feed port 6 for storage.

[0053] In order to prevent the asphalt regeneration material remaining on the discharge plate 9 from being spilled onto the top wall of the storage tank 5 during the process of the carrier plate 7 rotating and switching the storage tank 5, refer to Figure 3 and Figure 4 The top wall of the storage tank 5 is provided with convex strips 20 on both sides of the feed port 6. The convex strips 20 are arc-shaped, and the circle where the convex strips 20 are located coincides with the center of the carrier plate 7. The convex strips 20 are provided with a guide surface 21 at one end close to the feed port 6. The guide surface 21 is inclined toward the feed port 6. The guide surface 21 can be a plane or an arc surface. In the embodiment of the present application, the guide surface 21 is an arc surface, and the discharge plate 9 is movably in contact with the convex strips 20.

[0054] When it is necessary to switch the storage tank 5 to store the asphalt recycled material, the rotating assembly 18 is started, the rotating assembly 18 drives the bearing plate 7 to rotate, the bearing plate 7 drives the connecting plate 19 to rotate, and the connecting plate 19 drives the discharge plate 9 to rotate. The end of the discharge plate 9 away from the connecting plate 19 is driven by the guide surface 21 of the convex strip 20 to rotate in the direction away from the storage tank 5, and the rotating strip 27 is bent at this time. When the discharge plate 9 moves to abut against the top surface of the convex strip 20, the end of the discharge plate 9 away from the connecting plate 19 is higher than the end of the discharge plate 9 close to the connecting plate 19. Since the rotating strip 27 is made of spring steel, the discharge plate 9 is stably pressed against the end surface of the convex strip 20 away from the storage tank 5 under the elastic force of the rotating strip 27, so as to avoid the asphalt recycled material retained on the discharge plate 9 from spilling on the top wall of the storage tank 5 as much as possible.

[0055] In order to ensure that the asphalt recycled material can be stably stored in the storage tank 5, refer to Figure 3 and Figure 4 A door panel 22 is provided on the storage tank 5 at the feed port 6. A control module 23 for controlling the opening and closing of the door panel 22 is provided on the end surface of the convex strip 20 away from the storage tank 5. The control module 23 includes a sensor embedded in the convex strip 20 and a power member for driving the door panel 22 to open and close, and the sensor is electrically connected to the power member.

[0056] The carrying plate 7 drives the unloading plate 9 to rotate. When the unloading plate 9 rotates to the sensor, the sensor transmits an electrical signal to the power component, and the power component drives the door panel 22 on one side to open and the door panel 22 on the other side to close, so that when the unloading plate 9 rotates to the opened door panel 22, the unloading plate 9 can be connected with the storage tank 5 through the feed port 6 there, and the asphalt recycled material on the unloading plate 9 can be introduced into the storage tank 5 through the feed port 6 for storage.

[0057] Since the viscosity of asphalt recycled materials is also affected by temperature, Figure 3 and Figure 4 The storage tank 5 is provided with a temperature control system 24, which is a heating layer with a resistance wire, which is bonded to the inner wall of the storage tank 5, and a heat-insulating layer 25 is bonded to the outer wall of the storage tank 5. The temperature control system 24 can control the temperature in the storage tank 5, so that the temperature in the storage tank 5 is maintained within a set temperature range, reducing the viscosity of the asphalt recycled material and ensuring the quality of the asphalt recycled material in the storage tank 5. At the same time, the setting of the heat-insulating layer 25 can reduce the loss of heat in the storage tank 5, which can not only achieve the effect of energy saving and environmental protection, but also assist the temperature control system 24 in maintaining the stability of the temperature in the storage tank 5.

[0058] The implementation principle of a continuous asphalt plant hot-mixed recycled mixture mixing station in the embodiment of the present application is as follows: the rotating assembly 18 is started, and the rotating assembly 18 drives the carrier plate 7 to rotate, so that the discharge plate 9 on the carrier plate 7 is aligned with the feed port 6 of one of the storage tanks 5. The asphalt recycled material is then crushed and screened by the screening and crushing system 1, and then transmitted to the regeneration drying drum 3 through the lifting system 2 for drying and solidification. The dried and solidified asphalt recycled material is transmitted to the storage tank 5 through the conveying system 4.

[0059] Asphalt regeneration material falls from the gap between the feed barrel 17 and the inner casing 26 onto the carrier plate 7. At this time, the driving member 132 is started, and the driving member 132 drives the threaded ring 12 to rotate. The rotating threaded ring 12 stirs and transmits the asphalt regeneration material on the carrier plate 7. When the threaded ring 12 drives the injection head 112 to rotate to align with the injection head 14, the anti-sticking agent in the storage barrel 10 is poured into the infusion pipe 111. The anti-sticking agent in the infusion pipe 111 overflows onto the carrier plate 7 through multiple overflow holes. When the rotating threaded ring 12 stirs the asphalt regeneration material on the carrier plate 7, the anti-sticking agent can fully contact with the asphalt regeneration material particles, thereby improving the bonding problem of the asphalt regeneration material. The asphalt regeneration material after mixing moves toward the direction close to the drop hole 8 under the push of the threaded ring 12. The mixed asphalt regeneration material is transported to the storage tank 5 through the drop hole 8, the discharge plate 9 and the feed port 6 in turn for storage.

[0060] 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.
