The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0020] An embodiment of the present invention provides an asphalt recycled material mixer, as Figures 1 - 3As shown in the figure, the asphalt recycling material mixer includes: a base 1; a mixing box 2, which is fixedly installed on the base 1. A funnel-shaped partition 3 is fixedly installed in the mixing box 2. The funnel-shaped partition 3 divides the mixing box 2 into a pretreatment chamber 4 in the upper part and a stirring chamber 5 in the lower part; a storage tank 6, which is fixedly installed on the base 1 and is used to store new asphalt and recycling agent; a blower 7, which is fixedly installed on the top of the mixing box 2. The air outlet end of the blower 7 is fixedly communicated with a heat preservation shell 8. A heating element 9 is arranged in the heat preservation shell 8 and is laid on the air outlet end of the blower. The air outlet end of the heat preservation shell 8 is fixedly communicated with a corrugated cloth air duct 10, and the air outlet end of the corrugated cloth air duct 10 extends into the pretreatment chamber 4; a turning mechanism, which is arranged on the mixing box 2 and is used to turn the waste asphalt during heating.

[0021] In this embodiment, the base 1 serves as the support structure of the entire mixer, ensuring the stability and safety of the equipment. The interior of the mixing box 2 is divided into a pretreatment chamber 4 and a stirring chamber 5 by the funnel-shaped partition 3, enabling the waste asphalt to be first heated and pretreated in the pretreatment chamber 4 and then enter the stirring chamber 5 to be mixed with new asphalt, recycling agent and other materials, improving the mixing uniformity and efficiency. The unique shape of the funnel-shaped partition 3 not only effectively separates the pretreatment and stirring areas but also may play a role in guiding the material flow, promoting the smooth transfer of the waste asphalt. The pretreatment chamber 4, as the heating and pretreatment area of the waste asphalt, realizes the rapid heating and softening of the waste asphalt through the hot air introduced by the blower 7 and the corrugated cloth air duct 10, preparing for the subsequent mixing with new materials. In the stirring chamber 5, the pretreated waste asphalt is fully mixed with new asphalt, recycling agent and other materials to form high-quality recycled asphalt. The storage tank 6 is used to store new asphalt and recycling agent, facilitating replenishment into the stirring process at any time and ensuring the continuity and stability of the mixing operation. The blower 7, the heat preservation shell 8 and the heating element 9 form a hot air supply system. The blower 7 transports the hot air generated by the heating element 9 in the heat preservation shell 8 to the pretreatment chamber 4, realizing the uniform heating of the waste asphalt and improving the pretreatment efficiency. The turning mechanism is arranged on the mixing box 2 and is used to turn the waste asphalt during heating, enhancing the heat transfer effect, preventing the asphalt from caking and further improving the pretreatment quality. Through the pretreatment process, the waste asphalt is fully softened and uniformly heated, which is beneficial to the subsequent mixing with new materials and improves the overall quality of the recycled asphalt.

[0022] In a further preferred embodiment of the present utility model, the turning mechanism includes a transverse movement motor 11, a transverse movement screw 12, a sliding seat 13, and a turning plate 14. The transverse movement motor 11 is fixedly installed on the upper part of one side of the mixing box 2. The transverse movement screw 12 is rotatably installed on the mixing box 2. One end of the transverse movement screw 12 is fixedly connected to the output shaft of the transverse movement motor 11. The sliding seat 13 is threadedly installed on the transverse movement screw 12. The sliding seat 13 is in sliding fit with the inner top wall of the pretreatment chamber 4. The sliding seat 13 is connected to the corrugated cloth air duct 10. The turning plate 14 is fixedly installed on one side of the sliding seat 13.

[0023] In this embodiment, the transverse movement motor 11 serves as the power source of the turning mechanism and is fixedly installed on one side of the mixing box 2. The transverse movement motor 11 drives the transverse movement screw 12 to rotate through its output shaft, providing power for the transverse movement of the sliding seat 13. One end of the transverse movement screw 12 is fixedly connected to the output shaft of the transverse movement motor 11. The threaded part of the transverse movement screw 12 cooperates with the sliding seat 13 to convert the rotational movement of the motor into the linear movement of the sliding seat 13. The sliding seat 13 is threadedly installed on the transverse movement screw 12 and can move along its axial direction under the drive of the screw rotation. The sliding seat 13 is in sliding fit with the inner wall of the pretreatment chamber 4, ensuring stability and sealing during the movement. In addition, the sliding seat 13 is also connected to the corrugated cloth air duct 10. The corrugated cloth air duct is L-shaped and can be stretched a certain distance along the horizontal direction, which helps to guide the hot air more evenly to different areas of the pretreatment chamber 4. However, the specific connection method and its influence on the hot air distribution need further analysis. The turning plate 14 is fixedly installed on one side of the sliding seat 13 and moves with the transverse movement of the sliding seat 13. The turning plate 14 acts directly on the waste asphalt and turns the asphalt through its movement to prevent it from caking and promote heat transfer. The turning action of the turning plate 14 causes the waste asphalt to continuously turn in the pretreatment chamber 4, increasing the contact area between the asphalt and the hot air, thereby improving the heat transfer efficiency and enabling the asphalt to reach the required softening temperature faster and more evenly. Through continuous turning, large particles and caking in the waste asphalt are effectively broken up, avoiding problems such as uneven heating caused by caking and subsequent mixing difficulties.

[0024] In a further preferred embodiment of the present utility model, a stirring motor 15 is fixedly installed on one side of the mixing box 2. A stirring rod 16 is rotatably installed on the stirring chamber 5. One end of the stirring rod 16 is fixedly connected to the output shaft of the stirring motor 15. A plurality of stirring blades are provided on the stirring rod 16.

[0025] In this embodiment, the stirring motor 15 is fixedly installed on one side of the mixing tank 2 and serves as the power source of the stirring mechanism. The stirring motor 15 drives the stirring rod 16 to rotate through its output shaft, thereby realizing the mixing of the materials in the stirring chamber 5. The stirring rod 16 is rotatably installed on the stirring chamber 5, and one end of it is fixedly connected to the output shaft of the stirring motor 15. The stirring rod 16 rotates under the drive of the motor, driving the stirring blades arranged thereon to mix the materials in the stirring chamber 5. The stirring blades are arranged on the stirring rod 16 and are multiple in number, which is used to increase the contact area between the stirring rod 16 and the materials and improve the stirring effect. The shape and arrangement of the stirring blades may be optimized to ensure that the materials can be fully mixed during the stirring process and dead corners are not easily generated. The stirring motor 15 drives the stirring rod 16 and the stirring blades to rotate, fully mixing the materials such as waste asphalt, new asphalt, and regenerant in the stirring chamber 5, ensuring uniform distribution of each component, and improving the quality stability of the recycled asphalt.

[0026] In a further preferred embodiment of the present utility model, a feeding pump 17 is fixedly installed on the base 1. The feeding end of the feeding pump 17 is fixedly communicated with a feeding pipe 18, the feeding end of the feeding pipe 18 extends into the storage tank 6, the discharging end of the feeding pump 17 is fixedly communicated with a feeding pipe 19, and the discharging end of the feeding pipe 19 extends into the stirring chamber 5.

[0027] In this embodiment, the feeding pump 17 is fixedly installed on the base 1 and serves as the power for material transportation. The feeding pump 17 sucks the materials (such as new asphalt and regenerant) in the storage tank 6 and transports them into the stirring chamber 5 through the feeding pipe 19 according to its working principle (such as centrifugal pump, plunger pump, etc.). The feeding end of the feeding pipe 18 extends into the storage tank 6 and is used to connect the feeding pump 17 and the storage tank 6. The feeding pipe 18 ensures that the materials can be smoothly sucked into the feeding pump 17 from the storage tank 6 and is a key component of the material transportation path. The discharging end of the feeding pipe 19 extends into the stirring chamber 5 and is used to introduce the materials transported by the feeding pump 17 into the stirring chamber 5. The introduction of the feeding pump 17 and its pipeline realizes the automatic transportation of materials from the storage tank 6 to the stirring chamber 5, reduces manual operation, improves production efficiency and safety. By precisely controlling the transportation volume of the feeding pump 17, it can be ensured that the amount of materials added each time meets the production requirements, reducing material waste caused by excessive or insufficient amounts.

[0028] In a further preferred embodiment of the present utility model, a feeding hopper 20 is fixedly communicated with one side of the pretreatment chamber 4, a discharge port 21 is opened on one side of the stirring chamber 5, and a discharge plate 22 is arranged on the discharge port 21. The discharge plate 22 is inclined.

[0029] In this embodiment, the feed hopper 20 is fixedly connected to one side of the pretreatment chamber 4, providing a convenient channel for feeding waste asphalt. The discharge port 21 is opened on one side of the mixing chamber 5 for discharging the uniformly mixed recycled asphalt. The discharge plate 22 is arranged on the discharge port 21 and is inclined. The design of the discharge plate 22 helps to guide the flow direction of the recycled asphalt so that it can be smoothly discharged along the inclined surface.

[0030] In a further preferred embodiment of the present utility model, an electric telescopic rod 23 is fixedly installed on one side of the mixing box 2. The output rod of the electric telescopic rod 23 is provided with a baffle plate 24, and the baffle plate 24 is adapted to the discharge port 21 and the discharge plate 22.

[0031] In this embodiment, the electric telescopic rod 23 is fixedly installed on one side of the mixing box 2 and serves as a power source for controlling the movement of the baffle plate 24. Through its telescopic movement, the electric telescopic rod 23 drives the baffle plate 24 to perform opening and closing operations at the discharge port 21 and the discharge plate 22, thereby achieving precise control of the discharge process of the recycled asphalt. The shape and size of the baffle plate 24 should be carefully designed to ensure that it can closely fit the edges of the discharge port 21 and the discharge plate 22 to form an effective seal. When the electric telescopic rod 23 contracts, the baffle plate 24 opens to allow the recycled asphalt to be discharged from the discharge port 21. When the electric telescopic rod 23 extends, the baffle plate 24 closes to prevent the recycled asphalt from continuing to be discharged.

[0032] In a further preferred embodiment of the present utility model, a feeding pipe is provided on the funnel-shaped partition 3, and a sealing valve is provided on the feeding pipe. The feeding pipe is used to discharge the waste asphalt in the pretreatment chamber 4 into the mixing chamber 5.

[0033] In this embodiment, the feeding pipe is arranged on the funnel-shaped partition 3, connecting the pretreatment chamber 4 and the mixing chamber 5. The feeding pipe provides a direct channel for the waste asphalt, enabling it to be smoothly discharged from the pretreatment chamber 4 into the mixing chamber 5 for subsequent mixing treatment. The sealing valve is installed on the feeding pipe to control the opening and closing state of the feeding pipe. The presence of the sealing valve ensures the sealing performance of the waste asphalt during the transfer process, preventing material leakage and pollution.

[0034] In summary, compared with the related technologies, this device realizes the efficient, automatic regeneration treatment and precise control of waste asphalt as a whole. By integrating functional modules such as pretreatment, mixing and stirring, automatic feeding and discharging, it not only significantly improves the production efficiency, reduces manual intervention, and reduces material waste and environmental pollution.
