Description

Technical Field

[0001] This utility model belongs to the technical field of asphalt mixing equipment, specifically relating to a downstream asphalt mixture recycling equipment. Background Technology

[0002] my country generates a massive amount of waste asphalt mixtures annually from road maintenance and reconstruction. Simply dumping these waste materials occupies vast amounts of land resources, and the asphalt and fine aggregates within them cause long-term pollution of soil and water bodies, representing a significant waste of resources. Therefore, recycling and reusing waste asphalt mixtures is a crucial step in implementing a sustainable development strategy and developing a circular economy.

[0003] Currently, hot-mix asphalt recycling is the most widely used and relatively mature asphalt recycling method. It involves reheating and mixing a certain proportion of old asphalt with new asphalt, recycling agents, and new aggregates in specialized equipment to produce recycled asphalt mixtures that meet road use requirements. However, traditional equipment often has simple open-type feed inlets, which easily generate large amounts of dust when adding cold, wet old asphalt and powdered recycling agents, polluting the working environment and endangering the health of operators. The shaft seals of the mixing tank also often have poor sealing, allowing asphalt fumes to escape during mixing. Furthermore, when discharging the finished product, traditional equipment may experience material spillage and leakage due to improperly closed discharge gates or mismatched collection devices, resulting in material loss, additional cleaning, and reduced production efficiency.

[0004] In summary, existing asphalt mixture recycling equipment still needs improvement in terms of sealing and environmental friendliness, mixing efficiency, and ease of discharge collection.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, such as Figure 1 As shown, a downstream asphalt mixture recycling equipment includes a support column 1 with a fixed base 2 at its bottom. The support column 1 serves as the supporting structure for the entire equipment, steadily raising the mixing tank 3 to a suitable working height. The fixed base 2 is located at the bottom of the support column 1 and is used to fix the equipment to the foundation or working platform, providing a stable foundation. The support column 1 and the fixed base 2 ensure the overall stability and safety of the equipment during the mixing operation, preventing it from tipping over due to vibration or load. The design of the fixed base 2 enhances the equipment's anti-tipping ability.

[0022] A mixing tank 3 is installed at the top of support column 1. Mixing tank 3 is the core chamber of the equipment, where all materials, including waste asphalt mixture, new aggregate, and recycling agent, are heated, stirred, and mixed to complete the recycling process. As a sealed container, mixing tank 3 effectively prevents dust and asphalt fumes from escaping, ensuring a safe working environment. A feeding port 4 is located at the top of mixing tank 3, serving as the inlet for solid materials. A conical discharge port 15 is located at the bottom of mixing tank 3. After mixing, the mixed recycled material gathers by gravity into the conical discharge port 15. The conical design facilitates the concentrated, smooth, and thorough discharge of materials, reducing residue.

[0023] The top of the mixing tank 3 is also equipped with a stirring motor. The output end of the stirring motor extends into the interior of the mixing tank 3 and is equipped with stirring blades. The stirring motor is the drive source. It drives the stirring blades to rotate through the output shaft, which strongly stirs and mixes the materials in the tank. It provides strong and controllable stirring power, ensures that the materials are mixed evenly, the regenerator is fully dispersed, and the quality of the recycled material is guaranteed.

[0024] A liquid injection pipe 13 is installed on the side wall of the mixing tank 3. This pipe serves as a conduit for the liquid regenerant, allowing for independent and precise addition of the liquid component. This avoids interference with solid feed, and the closed-loop pipeline reduces the possibility of liquid evaporation and leakage, making it environmentally friendly and saving raw materials. A collection box 18 is located below the conical discharge port 15, connected to the outer wall of the port. A discharge gate 16 is located at the bottom of the collection box 18. The collection box 18 receives the finished recycled material discharged from the conical discharge port 15. The discharge gate 16, located at the bottom of the collection box 18, is used to finally unload the collected material, forming an integrated, closed finished material collection system. This completely prevents spillage and leakage of the finished material before final loading or bagging, reducing material loss and on-site pollution. The collection box 18 is directly connected to the discharge port, resulting in a compact structure that improves the efficiency and cleanliness of the discharge operation.

[0025] The specific design of the aforementioned key components will be discussed in detail below:

[0026] The feeding port 4 is inverted conical in shape, and a flip cover 6 is provided at the top of the feeding port 4. The flip cover 6 is hinged to the side wall of the feeding port 4 via a rotating shaft 8. The inverted conical feeding port 4 is designed to facilitate material introduction, the flip cover 6 is used to close the inlet of the feeding port 4, and the rotating shaft 8 enables the flexible opening and closing of the flip cover 6. A handle 7 is provided at the top of the flip cover 6 for easy opening and closing. A fixed support 5 is provided on the side wall of the feeding port 4 to enhance the fixing structure. The inverted conical design makes feeding smoother, reduces dust and material splashing, and the hinged flip cover 6 structure enables convenient opening and effective sealing of the feeding port 4, maintaining the airtightness of the mixing vessel 3 when not feeding, locking in heat and odor.

[0027] One end of the stirring motor is electrically connected to the controller 10, which is located on one side of the top of the mixing vessel 3. A dust cover 9 is installed outside the stirring motor, extending from the motor to the controller 10. The dust cover 9 protects the stirring motor from dust contamination. The controller 10 controls the motor's start / stop and speed. The dust cover 9 effectively extends the service life and operational reliability of the stirring motor, while the controller 10 achieves automated and precise control, improving production efficiency.

[0028] The side wall of the mixing vessel 3 is also equipped with an observation door 11, and a handle 12 is provided on the observation door 11. The observation door 11 is an openable door with a viewing window located on the side wall of the mixing vessel 3, used to observe the stirring state and mixing degree of the materials inside the vessel. The handle 12 is used to easily open and close the observation door 11. This allows operators to visually monitor the production process without interrupting production, facilitating timely adjustment of process parameters or detection of problems. The easy-to-open design also facilitates internal inspections and minor cleaning of the equipment.

[0029] The top of the injection pipe 13 is provided with a filling port 14. The filling port 14 is the inlet of the injection pipe 13, and can usually be connected to a hose or funnel. A pull handle switch 17 for controlling the discharge is provided on one side of the outer end of the conical discharge port 15. The pull handle switch 17 is a valve mechanism for controlling the opening and closing of the conical discharge port 15. The pull handle switch 17 is simple and reliable to operate and can accurately control the discharge flow rate and timing.
