Description

Technical Field

[0001] This utility model belongs to the field of recycled asphalt pavement production and processing technology, specifically relating to a stripping device for treating false particles in RAP material. Background Technology

[0002] RAP stands for Recycled Asphalt Mixture, which is an important material for 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 and aggregates such as crushed stone and sand, as well as possible residual additives. After recycling, it can be reused in asphalt pavement construction, which reduces costs and environmental burden, and is one of the core means of sustainable infrastructure construction.

[0003] RAP (Rich Acid Asphalt Powder) contains a large number of granular asphalt agglomerates composed of asphalt, mineral powder, and coarse and fine aggregates. These agglomerates contain a significant amount of asphalt and are similar in size to the aggregate particles; these are referred to as "pseudo-agglomerates." If these pseudo-agglomerates are not dispersed, they will be mistaken for aggregates of the same size and used in asphalt mixture design. This can lead to gradation deviations, increased asphalt content, segregation, and unstable asphalt pavement quality, creating potential for pavement damage. Furthermore, due to the high asphalt content in pseudo-agglomerates, they are prone to high-temperature aging and quality degradation during heating, resulting in increased smoke pollution and a risk of high-temperature fires.

[0004] In the existing technology, there is a lack of solutions for dealing with false particles during the processing of RAP materials. Generally, the RAP material is simply crushed and added, and the false particles are treated as stones of the same size. This cannot effectively eliminate the false particles, and the presence of false particles often leads to technical problems that affect the quality and safety of RAP materials during use. Utility Model Content

[0005] To address the lack of a treatment solution for false particles in the prior art, the common practice is to simply crush and add RAP material, treating the false particles as stones of the same size. This approach fails to effectively eliminate the false particles, often resulting in issues affecting the quality and safety of RAP material during use. This invention provides a stripping device for treating false particles in RAP material.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] The crushing mechanism is located on the upper part of the main shaft and includes multiple crushing connecting rods fixed on the main shaft for crushing RAP material entering from the feed inlet;

[0012] The stripping mechanism is located below the crushing mechanism. The stripping mechanism includes a rigid impact member and an elastic brush member, which are used to disperse and brush away false particles in the RAP material, respectively.

[0013] Optionally, the peeling mechanism includes a plurality of peeling links, which are arranged perpendicular to the main shaft;

[0014] The rigid impact component includes multiple breaking teeth, which are symmetrically arranged on the peeling link and are all located in a plane perpendicular to the main shaft.

[0015] The elastic brush sweeper includes multiple brush bodies, all of which are fixedly mounted on the peeling link, wherein some of the brush bodies and the crushing teeth are alternately arranged on the same plane;

[0016] The other brushes are symmetrically arranged on the peeling link and are all on the same plane as the main shaft.

[0017] Optionally, the breaking teeth are umbrella-shaped or tower-shaped multi-stage boss teeth.

[0018] Optionally, the brush body is made of multiple highly elastic manganese steel wires.

[0039] See Figures 1 to 4 The diagram shows a stripping device for treating RAP material particles provided in this utility model, comprising:

[0040] Tank 1, with an inlet and an outlet at its upper and lower ends respectively; a guide channel is provided on the inner wall of the tank, and the guide channel is arranged in a ring along the inner wall of the tank 1.

[0041] Drive component 2 is positioned above tank body 1;

[0042] Main shaft 3 is connected to drive component 2 and is inserted into tank 1 from top to bottom;

[0043] A crushing mechanism 4 and a stripping mechanism 5 are sequentially arranged along the axial direction of the main shaft 3;

[0044] The crushing mechanism 4 is located on the upper part of the main shaft 3 and includes multiple crushing connecting rods 41 fixed on the main shaft 3 for crushing RAP material entering from the feed inlet;

[0045] The stripping mechanism 5 is located below the crushing mechanism 4. The stripping mechanism 5 includes a rigid impact member and an elastic brush member, which are used to disperse and brush away false particles in the RAP material, respectively.

[0046] In this embodiment, the airtight structure of the tank 1 ensures no dust leakage during operation. The layout of the drive unit 2, positioned above the tank 1 and connected to the main shaft 3, makes power transmission more direct and efficient, ensuring the stable operation of the entire device. The crushing mechanism 4, located above the main shaft, can initially crush the incoming RAP material. The stripping mechanism 5, through the synergistic action of rigid impact components, can effectively impact and disperse the pseudo-particles in the RAP material. At the same time, the elastic brushing component thoroughly brushes away the dispersed pseudo-particles, ensuring that they are fully processed. This segmented processing flow has significant advantages over traditional single crushing equipment. It can adopt differentiated processing methods for the special properties of pseudo-particles, greatly improving processing efficiency and effectiveness, and providing reliable technical support for the resource utilization of RAP material.

[0047] Meanwhile, during use, the flow channel is used to guide the RAP material in the tank 1 to prevent turbulence, which would cause the RAP material to fly around or even fly out of the tank 1 due to the collision of the crushing mechanism 4 and the stripping mechanism 5.

[0048] Optionally, refer to Figure 2 The peeling mechanism in this utility model includes multiple peeling links 51, which are arranged perpendicularly to the main shaft 3.

[0049] The rigid impact component includes multiple breaking teeth 52, which are symmetrically arranged on the peeling link 51 and are all located in a plane perpendicular to the main shaft 3.

[0050] The elastic brush sweeper includes multiple brush bodies 53, all of which are fixedly mounted on the peeling link 51. Some of the brush bodies 53 and the crushing teeth 52 are alternately arranged on the same plane.

[0051] The other brush bodies 53 are symmetrically arranged on the stripping link 51, and are all on the same plane as the main shaft 3.

[0052] In this embodiment, the specific structure of the peeling mechanism 5 is further optimized. Multiple peeling links 51 are arranged perpendicularly to the main shaft, making force transmission more uniform and stable, thus improving the operational stability of the device. The symmetrical arrangement of the crushing teeth 52 on the peeling links 51 and on a plane perpendicular to the main shaft 3 ensures a balanced distribution of crushing force, avoiding uneven loading and extending the equipment's service life. The design of the brush body 53 fixedly mounted on the peeling links 51 provides a stable working platform. The innovative layout of some brush bodies 53 and crushing teeth 52 alternately arranged on the same plane achieves seamless integration of crushing and brushing functions, enabling immediate brushing of dispersed false particles during processing, improving processing efficiency. The symmetrical arrangement of other brush bodies 53 on the peeling links 51 and on the same plane as the main shaft 3 increases the brushing coverage, ensuring no processing dead zones. This structural design allows the peeling mechanism 5 to maximize its efficiency when processing false particles. The impact of the crushing teeth 52 and the brushing action of the brush bodies 53 complement each other, working together to eliminate false particles, significantly improving processing effect and operational efficiency.

[0053] Optionally, refer to Figure 2 The breaking teeth 52 in this utility model are multi-stage boss teeth in the shape of umbrellas or towers.

[0054] In this embodiment, the umbrella-shaped or tower-shaped structural design allows the crushing teeth 52 to impact the pseudo-particles with their tips during rotation, improving the crushing efficiency. The multi-stage protrusions also ensure a more uniform distribution of crushing force, avoiding excessive impact on a single point and reducing energy loss. This shape of the crushing teeth performs exceptionally well when handling highly adhesive pseudo-particles, effectively overcoming the adhesion of asphalt materials and achieving complete dispersion of the pseudo-particles. Simultaneously, this structural design improves the wear resistance and service life of the crushing teeth, reduces equipment maintenance costs, and provides a reliable guarantee for the long-term stable operation of the device.

[0055] Optionally, the brush body 53 in this invention is made of multiple high-elasticity manganese steel wires.

[0056] In this embodiment, the brush body 53, made of high-elasticity manganese steel wire, possesses excellent mechanical properties and durability. Its high elasticity allows the brush body 53 to maintain good shape recovery during operation, preserving its original brushing effect even after prolonged use. The high strength and wear resistance of the manganese steel wire ensure long-term stable operation of the brush body under harsh working conditions, reducing replacement frequency and maintenance costs. This material performs exceptionally well when handling highly adhesive asphalt materials, effectively removing the asphalt film from the aggregate surface without causing excessive damage to the aggregate itself, thus maintaining its integrity and usability. High elasticity also allows the brush body to adapt to aggregate surfaces of different shapes and sizes, ensuring comprehensive and consistent brushing results. The manganese steel wire material also exhibits good corrosion resistance, resisting the erosion of chemicals that may be present in the RAP material, extending the brush body's service life. This material selection fully considers the needs of the actual operating environment, providing material-level assurance for the reliable operation of the device.

[0057] Optionally, refer to Figure 3 The crushing mechanism 4 in this utility model includes multiple crushing connecting rods 41, which are arranged perpendicularly to the main shaft 3.

[0058] Multiple crushing teeth 52 are symmetrically arranged on the crushing connecting rod 41, and all the crushing teeth 52 are located on a plane perpendicular to the main shaft 3.

[0059] In this embodiment, the specific structure of the crushing mechanism 4 is further refined. The design of multiple crushing connecting rods 41 perpendicular to the main shaft 3 makes the transmission of crushing force more direct and efficient, improving energy utilization. The symmetrical arrangement of multiple crushing teeth 52 on the crushing connecting rods 41, all located on a plane perpendicular to the main shaft 3, ensures the balance and stability of the crushing operation, avoiding vibration problems caused by uneven force. This symmetrical arrangement also allows the crushing teeth 52 to simultaneously impact the RAP material at multiple points and in multiple directions, improving crushing efficiency and uniformity. The design of the crushing teeth on the same plane ensures the coordination of the crushing operation; all crushing teeth work together to form a combined force, enhancing the crushing effect. This structural design is suitable for processing blocky RAP material, quickly crushing it into particle sizes suitable for subsequent processing, creating favorable conditions for the operation of the stripping mechanism 5. At the same time, this standardized and symmetrical design also facilitates manufacturing and maintenance, reduces production costs and maintenance difficulty, and improves the economy and practicality of the device.

[0060] Optionally, the main shaft 3 of this utility model is also provided with a cleaning mechanism 6; the cleaning mechanism (6) is located below the peeling mechanism 5 and includes a brush body connecting rod 61 fixed on the main shaft 3, which is used to perform deep cleaning on the RAP material after peeling.

[0061] Optionally, refer to Figure 4The cleaning mechanism 6 in this utility model includes multiple brush body connecting rods 61, which are arranged perpendicularly to the main shaft 3.

[0062] Multiple brushes 53 are symmetrically arranged on the brush body connecting rod 61.

[0063] In this embodiment, the layout of multiple brushes 53 symmetrically arranged on the brush body connecting rod 61 achieves full coverage of the brushing operation and avoids the generation of dead corners. The symmetrical arrangement ensures the balanced distribution of brushing force, improves the quality and efficiency of the operation, and enables the cleaning mechanism 6 to perform final finishing on the RAP material after the first two processes, thoroughly remove the residual asphalt film on the surface of the aggregate, and improve the purity and usability of the recycled aggregate.

[0064] Specifically, the method of using the stripping device for treating RAP material false particles provided in this embodiment includes:

[0065] S1: Start the drive unit to drive the main shaft, crushing mechanism, stripping mechanism and cleaning mechanism to rotate in the tank; pour the RAP material to be processed into the tank through the feed port;

[0066] S2: When the RAP material passes through the crushing mechanism, it is crushed by the impact of the crushing connecting rod; when the crushed RAP material falls to the stripping mechanism after crushing, the crushing teeth impact and disperse the false particles in the RAP material, and the brush body sweeps away the dispersed false particles to eliminate them.

[0067] S3: After the RAP material has been stripped, it falls to the cleaning mechanism, where it is deeply cleaned by the brush linkage to further remove residual asphalt. Finally, the stripped RAP material is discharged from the outlet.
