For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0029] Example 1 See also Figures 1 to 6 The present invention provides a waste asphalt mixture separation and recovery device, comprising a frame 1, a separation barrel 2 is fixedly arranged on the frame 1, a feed inlet is arranged at the upper end of the side wall of the separation barrel 2, and a discharge outlet is arranged at the lower end, a stripping mechanism 3 for stripping waste asphalt is arranged in the separation barrel 2, and a driving mechanism 4 for driving the stripping mechanism 3 to work; A conveyor 5 is arranged below the frame 1 , and an inlet end of the conveyor 5 is located below the discharge port of the separation barrel 2 .

[0030] When using the waste asphalt mixture separation and recovery device, first turn on the driving mechanism 4, which drives the stripping mechanism 3 to work. Then, pour the waste asphalt mixture into the separation barrel 2 from the feed port at the upper end of the side wall of the separation barrel 2. At this time, the driving mechanism 4 drives the stripping mechanism 3 in the separation barrel 2 to operate, and the spiral blades 14 rotate rapidly, driving various types of cutters to strip the waste asphalt mixture. After the separation is completed, the separated materials are discharged from the discharge port at the lower end of the separation barrel 2 and directly fall on the inlet end of the conveyor 5 below. The conveyor 5 transports the materials to the designated location.

[0031] The stripping mechanism 3 includes a rotating shaft 6 rotatably arranged inside the separation barrel 2, on which a primary inner stripping unit 7, a secondary inner stripping unit 8 and a tertiary inner stripping unit 9 are arranged, the primary inner stripping unit 7 is located above the secondary inner stripping unit 8, and the secondary inner stripping unit 8 is located above the tertiary inner stripping unit 9; A rotating frame 10 is also sleeved on the rotating shaft 6 , and a primary outer peeling unit 11 , a secondary outer peeling unit 12 and a tertiary outer peeling unit 13 are arranged on the rotating frame 10 . The primary outer peeling unit 11 is located above the secondary outer peeling unit 12 , and the secondary outer peeling unit 12 is located above the tertiary inner peeling unit 9 .

[0032] When the materials in the separation barrel 2 are accumulated to a certain height, the materials at different heights are subjected to different pressures, and the interior of the separation barrel 2 can be divided into three areas: upper, middle and lower. The materials in the upper area are stripped by the first-level internal stripping unit 7 and the first-level external stripping unit 11, the materials in the middle area are stripped by the second-level internal stripping unit 8 and the second-level external stripping unit 12, and the materials in the lower area are stripped by the third-level internal stripping unit 9 and the third-level external stripping unit 13.

[0033] The first-stage inner stripping unit 7 and the first-stage outer stripping unit 11 both include a spiral blade 14, and a plurality of sharp-toothed cutters 15 are arranged in an array along the outer edge of the blade 14; The secondary inner stripping unit 8 and the secondary outer stripping unit 12 both include a spiral blade 14, and a plurality of flat-toothed cutters 16 are arranged in an array along the outer edge of the blade 14; The three-stage inner stripping unit 9 and the three-stage outer stripping unit 13 both include a spiral blade 14 , and a plurality of scalloped cutters 17 are arranged in an array along the outer edge of the blade 14 .

[0034] Waste asphalt mixtures from different sources may have different properties such as the degree of asphalt aging and the bonding strength with aggregates. The pointed tooth cutter 15 is suitable for processing waste asphalt mixtures with high bonding strength and large material clumps, and can effectively crush and separate them with its sharp shape; the flat tooth cutter 16 can further separate materials with moderate bonding strength after preliminary treatment; the round tooth cutter 17 is used to process materials with low bonding strength and require fine processing. This combination of multi-stage and different cutters enables the separation and recovery device to adapt to a wider range of waste asphalt mixtures, thereby improving the versatility and applicability of the device.

[0035] The unique movement mode of the spiral blade 14 allows the material to circulate continuously in the process of longitudinal lifting and circumferential movement, which enables the material to pass through each level of stripping units more quickly and speeds up the separation speed; The bottom material is lifted to the upper layer and then falls down from the side and the blade 14. The material circulation formed ensures that all materials can pass through the stripping area repeatedly. No matter it is new material that has just entered the equipment or material that has not been completely processed before, it has multiple opportunities to be stripped, thereby ensuring that each piece of material can be fully stripped of asphalt, improving the recovery quality of aggregates; Ensure that the material is evenly distributed and continuously circulated in the processing chamber, avoiding excessive accumulation of materials in a certain place or concentrated impact on equipment components. This makes the force on each part of the equipment more balanced, reduces the risk of local wear and damage, extends the overall service life of the equipment, and reduces the frequency and cost of equipment maintenance.

[0036] The pointed-tooth cutter 15 comprises a cutter body in the shape of an isosceles trapezoid, and a plurality of triangular cutter heads are arranged in an array on two waists of the cutter body.

[0037] The waste asphalt mixture enters the separation barrel 2 from the feed port at the upper end of the side wall, and first contacts the sharp-toothed cutter 15 located at the upper layer. The triangular cutter head on the isosceles trapezoidal cutter body of the rotating sharp-toothed cutter 15 quickly cuts through the material. Since the material is in a loose state when it first enters, and the pressure in the upper layer is relatively small, and the force is easily moved upward, the surface asphalt is cut by the sharp-toothed cutter 15 with a sharp cutter head; After the sharp-toothed cutter 15 cuts and peels the material, part of the asphalt is separated, and the initially separated material continues to fall downward and enters the next-level peeling unit for further processing.

[0038] Specially designed for the characteristics of the upper layer of materials, the cutter head can better contact and cut the materials by taking advantage of the upward force of the materials. Compared with other shapes of cutter heads, it is more suitable for processing materials in this area, improving the pertinence and effectiveness of the entire separation process; The isosceles trapezoidal cutter body has a stable structure and can withstand greater cutting forces while carrying the triangular cutter head. The reasonable design of the cutter body prevents the cutter head from being damaged during the cutting process, thereby extending the overall service life of the sharp-tooth cutter 15 and reducing the frequency of tool replacement and maintenance costs.

[0039] The flat-tooth cutter 16 comprises a cutter body in the shape of an isosceles trapezoid, and a plurality of rectangular cutter heads are arranged in an array on two waists of the cutter body.

[0040] The waste asphalt mixture initially stripped by the sharp-toothed cutter 15 continues to fall and enters the middle layer. The rectangular cutter head on the isosceles trapezoidal cutter body of the rotating flat-toothed cutter 16 contacts the material falling there. Since the pressure on the material in the middle layer is moderate, the rectangular cutter head cuts into the asphalt on the surface of the material aggregate by virtue of its sharpness. The cutter head continuously cuts and peels the material during the rotation process, further removing the residual asphalt on the aggregate. After completing the separation work in the middle layer area, the material continues to fall downward and enters the next level of processing.

[0041] The rectangular cutter head has appropriate sharpness. When the pressure on the middle layer of material is moderate, it can accurately cut into the asphalt on the surface of the aggregate, effectively stripping the asphalt, ensuring the accuracy of the separation work and improving the separation quality.

[0042] The shape of the cutter head enables it to withstand greater loads and impacts. When processing middle-layer materials, even if it encounters some parts with higher hardness or tighter adhesion, the flat-tooth cutter 16 can work stably and is not easily damaged, thus ensuring the continuous and stable operation of the equipment.

[0043] Specially designed for the moderate pressure of the middle layer material, this tool shape and structure perfectly adapts to the characteristics of the middle layer material. Compared with other tool shapes, it can exert a better separation effect in this area and optimize the entire separation and recovery process.

[0044] The scalloped cutter 17 comprises a cutter body in the shape of an isosceles trapezoid, and a plurality of semicircular cutter heads are arranged in an array on two waists of the cutter body.

[0045] The material processed by the sharp-toothed cutter 15 and the flat-toothed cutter 16 falls into the lower processing area. At this time, the lower area is under great pressure due to the accumulation of a large amount of material above, and is in a state of difficult and slow movement; Through the rotating spherical tooth tool 17, the semicircular cutter head on its isosceles trapezoidal cutter body contacts the compressed material. Although the cutter head has given up sharpness, due to its high-strength structure, it can utilize a larger cutting depth when in contact with the material, forcibly cut into the material, and perform the final asphalt stripping on the material.

[0046] After the cutting process by the scalloped cutter 17 , the asphalt in the material is separated as much as possible, and the separated material is discharged from the discharge port of the separation barrel 2 and enters the subsequent conveyor 5 for transportation.

[0047] When the pressure of the lower material is high and the movement is slow, the semicircular cutter head of the spherical tooth cutter 17 has a high-strength structure, which ensures that it can still work normally at a large cutting depth, effectively overcome the resistance of the material, realize the stripping of the asphalt, and ensure the integrity of material processing.

[0048] Since the scalloped cutter 17 can withstand the huge pressure of the lower material, it is not easy to be damaged during the cutting process, which prolongs the service life of the cutter, reduces the cost of tool replacement, and improves the economy of the equipment.

[0049] In view of the characteristics of the lower layer material, a design that sacrifices sharpness in exchange for blade strength is adopted, so that the tool can play the maximum role in this area, optimize the entire material handling process, and improve the separation effect and recycling quality of waste asphalt mixture.

[0050] During the stripping process of waste asphalt mixture, since the entire tool is subjected to the impact and grinding of the material, the materials of the blade and the tool body are both made of high-speed steel. By using cutter heads with round teeth, flat teeth and pointed teeth respectively, the cutter heads are arranged in a continuous and evenly distributed form on the trapezoidal structure of the cutter body, ensuring that the asphalt mixture stripping task can be efficiently completed in different working areas.

[0051] The design parameters of the tool, such as the inclination of each blade and the tool tooth profile parameters, play a key role in the sharpness and strength of the cutting edge, and also directly affect the asphalt stripping efficiency, quality and cost. Taking the multi-pointed tooth knife as an example, the choice of the blade inclination is crucial. If the blade inclination is too small, the asphalt cutting effect will be greatly reduced; if the inclination is too large, the resistance during the cutting process will increase significantly, leading to serious wear of the tool; the choice of blade angle also requires careful consideration; when the blade angle takes a larger value, the strength of the blade teeth will increase, but it will have an adverse effect on the asphalt cutting effect; if the blade angle is too sharp, the blade teeth are prone to chipping, greatly shortening the service life of the tool.

[0052] Based on the above factors and according to the established initial structure of the tool, a series of tool design variables were determined. Specifically, the design variables of the multi-pointed tooth cutter are the cutter body inclination angle a and the blade angle b; the design variables of the multi-flat tooth cutter are the cutter body inclination angle c and the blade width d; and the design variables of the multi-circular tooth cutter are the cutter body inclination angle e and the blade height f.

[0053] After optimization analysis, the range and optimal values ​​of these design variables are as follows: the inclination angle a of the multi-pointed tooth cutter is preferably 13-17 degrees, of which 15 degrees is the optimal value; the blade angle b can be selected between 50-55 degrees, with 55 degrees being the best; The blade inclination angle c of the multi-flat tooth cutter is preferably 8-12 degrees, preferably 10 degrees; the blade width d is 1-3mm, and 2mm is the best choice; The blade inclination angle e of the multi-circular tooth cutter is recommended to be between 3-8 degrees, with 5 degrees being the preferred option; the blade height f is selected to be 2-4mm, with 3mm being the best option.

[0054] The highest points of the blades 14 of the secondary inner stripping unit 8 and the secondary outer stripping unit 12 are located above the lowest points of the blades 14 of the primary inner stripping unit 7 and the primary outer stripping unit 11; The highest points of the blades 14 of the tertiary inner peeling unit 9 and the tertiary outer peeling unit 13 are located above the lowest points of the blades 14 of the secondary inner peeling unit 8 and the secondary outer peeling unit 12 .

[0055] The material passes through different levels of stripping units in sequence, and the position of the blades 14 of each unit is reasonably designed, ensuring that the material can be processed step by step in sequence and stably. Each level of stripping is aimed at the remaining asphalt after the previous level of processing, making the asphalt stripping more thorough, improving the recovery quality and purity of the aggregate, and greatly improving the separation accuracy.

[0056] The materials flow in an orderly manner between the stripping units and can naturally enter the next level of processing without the need for additional guiding devices, which reduces the residence time of the materials in the equipment, increases the material processing volume per unit time, speeds up the separation and recovery process of the entire waste asphalt mixture, and improves production efficiency.

[0057] The driving mechanism 4 includes a bracket 18 fixedly mounted on the separation barrel 2, a driving motor 19 fixedly mounted on the bracket 18, a driving gear 20 coaxially fixedly mounted on the motor shaft of the driving motor 19, and the driving gear 20 is coaxially fixed with the rotating shaft 6; A gear rack 21 is fixedly mounted on the bracket 18, and a plurality of intermediate gears 22 are rotatably mounted on the gear rack 21. The plurality of intermediate gears 22 are evenly distributed on the outside of the driving gear 20 and mesh with the driving gear 20. A gear ring 23 is rotatably provided on the separation barrel 2 , the gear ring 23 is meshed with the intermediate gear 22 , and the gear ring 23 is coaxially fixed with the rotating frame 10 .

[0058] The driving motor 19 starts to run. The motor shaft drives the driving gear 20 fixed coaxially to start rotating. When the driving gear 20 rotates, the multiple intermediate gears 22 meshing therewith start rotating on the gear frame 21. During the rotation process, the intermediate gears 22 mesh with the ring gear 23, driving the ring gear 23 to rotate. Because the ring gear 23 is coaxially fixed with the rotating frame 10, the rotating frame 10 rotates with the ring gear 23. Due to the transmission effect of the intermediate gears 22, the rotating frame 10 rotates in the opposite direction to the rotating direction of the rotating shaft 6.

[0059] The waste asphalt mixture is fed into the separation barrel 2 from the feed port at the upper end of the side wall of the separation barrel 2, and the rotating shaft 6 drives the primary inner stripping unit 7, the secondary inner stripping unit 8 and the tertiary inner stripping unit 9 to rotate, while the reversely rotating rotating frame 10 drives the primary outer stripping unit 11, the secondary outer stripping unit 12 and the tertiary outer stripping unit 13 to rotate; The rotation directions of the blades 14 on the primary inner stripping unit 7 and the primary outer stripping unit 11, the secondary inner stripping unit 8 and the secondary outer stripping unit 12, the tertiary inner stripping unit 9 and the tertiary outer stripping unit 13 are opposite; The opposite rotation directions of the inner and outer stripping units at each level and the rotation direction of the blades 14 make the material subject to forces in different directions at each processing stage, which greatly enhances the disturbance degree of the material in the separation barrel 2, which helps the material to contact the cutter more fully and improves the separation efficiency and effect of asphalt and aggregate; Through multi-level and different-directional treatment, the waste asphalt mixture can be stripped more comprehensively and deeply. From the primary stripping to the third-level fine treatment, each stage can remove asphalt with different adhesion degrees, effectively improving the quality and purity of the recycled aggregates. Under the action of the counter-rotation of the rotating shaft 6 and the rotating frame 10, the material is subjected to forces in different directions, and can contact with the cutter more fully, thereby improving the stripping effect of asphalt and aggregate.

[0060] A filter screen is arranged at the discharge port of the separation barrel 2 .

[0061] The filter can screen the materials discharged from the discharge port after the stripping process. It can intercept large pieces of asphalt that have not been completely separated, impurities or other substances that do not meet the recycling standards, and only allow qualified aggregates to pass through. In this way, the aggregates finally recovered are of higher purity and more guaranteed quality, which can better meet the needs of subsequent reuse. For example, when used in projects such as road paving, it can improve the overall quality of the project.

[0062] When the present invention is used, when using the waste asphalt mixture separation and recovery device, first turn on the drive mechanism 4, the drive mechanism 4 drives the stripping mechanism 3 to work, then pour the waste asphalt mixture into the separation barrel 2 from the feed port at the upper end of the side wall of the separation barrel 2, at this time, the drive mechanism 4 drives the stripping mechanism 3 in the separation barrel 2 to operate, and the spiral blades 14 rotate rapidly, driving various types of cutters to strip the waste asphalt mixture, after the separation is completed, the separated materials are discharged from the discharge port at the lower end of the separation barrel 2, directly fall on the inlet end of the conveyor 5 below, and the conveyor 5 transports the materials to the designated location.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
