Description

Technical Field

[0001] This invention relates to the field of waste asphalt roll recycling technology, and in particular to a waste asphalt roll recycling and crushing equipment. Background Technology

[0002] Waste asphalt roofing membrane is a type of solid waste generated from building demolition and repair. It is an asphalt-based waterproof membrane made with base materials such as paper, fiberglass, and polyester fiber, impregnated with petroleum asphalt or polymer-modified asphalt, and covered with a release agent. It is a waste membrane that has reached the end of its service life in waterproofing projects such as roofs, basements, and tunnels, resulting in aging, cracking, blistering, and leakage. It is also leftover from building demolition, waterproofing renovation, membrane cutting, or production of substandard or defective products, rendering it unusable for waterproofing construction. The membrane mainly consists of aged asphalt, fiber matrix, plastic film, and mineral release agent powder, and is classified as construction waste containing asphalt solid waste. Some old coal tar pitch-based membranes also contain hazardous substances, requiring standardized collection, disposal, or resource recycling. The waste asphalt roofing membrane crushing and recycling process requires the use of crushing equipment to pulverize the membrane.

[0003] However, existing crushing equipment relies solely on a single crushing process, with materials being directly discharged after only one roller crushing and cutting. This results in insufficient crushing, inconsistent particle sizes, and difficulty in meeting the material standards for subsequent recycling, leading to poor stability in crushing quality. Furthermore, the material feeding stage suffers from a height difference between the equipment's feeding port and the ground, requiring manual lifting and delivery of the rolled material. Continuous material handling during large-scale recycling significantly increases the workload for operators, resulting in high labor costs and low efficiency. Additionally, the lack of a pre-installed impurity removal mechanism at the front end of the crushing equipment means that hard debris such as sand, metal blocks, and cement lumps easily adhere to the surface of waste asphalt rolls during recycling, stacking, and dismantling. When the rolls are fed directly into the crushing rollers without pre-treatment, these hard impurities continuously rub and impact the roller teeth and surface, causing wear, tooth breakage, and deformation over time. This shortens the lifespan of core components, increases downtime for maintenance, and raises overall processing costs. Summary of the Invention

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention features a two-stage crushing structure, combined with an internal airflow turning mechanism, to address the issues of insufficient pulverization and uneven particle size in traditional single-stage crushing, which makes it difficult to meet the standards for recycled materials. Two sets of crushing rollers complete the primary crushing and cutting, while the crushing barrel, with its built-in crushing blades, completes the secondary fine crushing. Simultaneously, an air pump, along with an air storage plate and a one-way nozzle, injects airflow into the crushing barrel, blowing up the asphalt roll powder that has settled at the bottom, preventing material from accumulating in dead corners and sticking to the walls, thus further improving the uniformity of material crushing. The dual crushing process, combined with airflow turning, ensures that the material is fully crushed and has a uniform particle size, meeting the standards for subsequent recycled processing and improving the stability of crushing and processing quality.

[0026] 2. This invention features an adjustable conveying and feeding mechanism, replacing traditional manual lifting and feeding operations, and is suitable for large-scale recycling and processing of waste asphalt rolls. The forward and reverse motors drive the conveyor belt to operate, and the conveyor belt clamps the waste asphalt rolls in both directions for limited conveying and feeding. The feeding is completed by matching the feeding height of the box with the fixed structure. There is no need for operators to manually lift and deliver the rolls. The clamping and conveying stability is strong, avoiding roll conveying deviation and slippage, reducing manual labor intensity, reducing manpower consumption, and improving the efficiency of waste asphalt roll feeding and overall crushing operations. It is suitable for large-scale recycling and crushing operations in industrial parks.

[0027] 3. This invention features an adjustable front-mounted scraper for removing impurities, suitable for pre-treatment and cleaning of rolled materials stacked on the ground. The connecting screw can slide along the through groove to adjust the vertical spacing. The mounting screw, in conjunction with the mounting nut, allows for the removal and installation of the scraper. The connecting nut can lock and position the overall structure. The scraper can remove stubborn impurities such as clumps of sand and gravel and thick layers of cement debris adhering to the bottom surface of the rolled material, preventing hard impurities from entering the crushing structure in advance. It has strong impurity removal adaptability, is easy to disassemble and maintain, reduces the impact and wear of hard impurities on the crushing roller and crushing blade components, optimizes the long-term operational stability of the equipment, and reduces the frequency of equipment failure and maintenance.

[0043] Please refer to Figures 1 to 10 As shown,

[0044] A waste asphalt roll recycling and crushing equipment includes a housing 1. Inside the housing 1, two sets of crushing rollers 2 are mounted and rotated via bearings. The two sets of crushing rollers 2 are arranged in parallel and are used to initially crush the waste asphalt rolls fed into the housing 1. Two sets of mounting covers 3 are bolted to the side walls of the housing 1. The two sets of mounting covers 3 are symmetrically distributed on both sides of the housing 1. Each set of mounting covers 3 has a drive motor 4 bolted to its outer side. The drive motor 4 is positioned and fixed by the mounting cover 3 and provides power for the operation of the crushing rollers 2. A frame 5 is bolted to the rear end face of the housing 1. The frame 5 is used for feeding and conveying operations. A feeding hopper 6 is fixed through the lower part of the housing 1. The hopper 6 receives the material after the initial crushing of the box 1. The discharge end of the hopper 6 is equipped with a crushing barrel 7 via a bearing. The crushing barrel 7 receives the material from the hopper 6 and completes secondary fine crushing. The outer walls on both sides of the box 1 are fixed with mounting seats 8 by bolts. Each set of mounting seats 8 has two sets of support columns 9 vertically welded to its lower end. The two sets of support columns 9 on the same side are arranged in parallel. The lower ends of all support columns 9 are welded together to fix the base 10. The support columns 9 bear the overall load of the box 1 and mounting seats 8 and transfer the load to the base 10. The lower part of the base 10 is vertically connected to a first electric telescopic rod 12. Multiple vertical rods 13 slide vertically through the lower part of the base 10. The telescopic end 12 and the upper end of the vertical rod 13 are jointly fixedly connected to the positioning plate. The vertical rod 13 limits the lifting trajectory of the positioning plate to ensure smooth lifting. The side wall of the positioning plate is rotatably connected to the air storage plate 14 through the bearing. The air storage plate 14 can rotate freely relative to the positioning plate. Multiple sets of unidirectional nozzles 15 are inserted and arranged at the upper end of the air storage plate 14. The unidirectional nozzles 15 spray air in a directional manner. The outer wall of the crushing barrel 7 is rotatably connected to the sleeve cover 20 through the bearing. Two sets of connecting rods 21 are symmetrically welded between the outer wall of the hopper 6 and the sleeve cover 20. The connecting rods 21 limit and fix the sleeve cover 20 below the hopper 6, so that the sleeve cover 20 and the crushing barrel 7 are coaxially arranged. The lower end of the sleeve cover 20 is fixed by bolts. A servo motor 22 is fixedly mounted, and the output end of the servo motor 22 is fixedly sleeved with the main gear 23. The driven gear 24 is fixedly sleeved on the outer wall of the crushing barrel 7. An air pump 16 is fixedly mounted on the upper end of the base 10 by bolts. The output end of the air pump 16 is snapped into the air guide hose 17. The end of the air guide hose 17 passes through the positioning plate. The air pump 16 delivers high-pressure gas to the air storage plate 14 through the air guide hose 17. A solenoid valve 18 is mounted on the body of the air guide hose 17. The solenoid valve 18 controls the opening and closing of the air guide hose 17 and regulates the start and stop of the air jet. Multiple sets of crushing blades 19 are fixedly mounted on the inner wall of the crushing barrel 7. The crushing blades 19 rotate synchronously with the crushing barrel 7 and work with the inner wall of the barrel to complete the secondary crushing operation of the asphalt roll.

[0045] Please refer to Figure 1 , Figure 2 ,and Figure 6As shown, multiple sets of conveyor rollers 25 are mounted inside the frame 5 via bearings. These rollers are arranged equidistantly laterally, and a conveyor belt 26 is connected to the outer side of all the rollers 25. The conveyor belt 26 automatically feeds waste asphalt rolls by rotating the rollers 25. A sealing cover 32 is bolted to one side of the outer wall of the frame 5, protecting the internal transmission structure. A reversible motor 33 is bolted to the outer side of the sealing cover 32, providing power for the conveyor belt 26. A second, third, fourth, fifth, sixth, and seventh sets of conveyor rollers 25 are mounted laterally through the rear end of the frame 5. Two electric telescopic rods 27 are connected to a concave frame 29. Multiple sets of guide rods 28 slide laterally through the rear end face of the frame 5. The telescopic end of the second electric telescopic rod 27 and the ends of all the guide rods 28 are fixedly connected to the concave frame 29. The guide rods 28 limit the horizontal movement trajectory of the concave frame 29 to prevent deviation. Multiple sets of mounting shafts 30 are mounted inside the concave frame 29 through bearings. The outer sides of the multiple sets of mounting shafts 30 are connected to the conveyor belt 31. The conveyor belt 31 moves synchronously with the concave frame 29 to adapt to the feeding of roll materials of different sizes. It works with the conveyor belt 26 to complete the flattening and feeding operation of the roll material.

[0046] Please refer to Figure 1 As shown, the output end of the forward and reverse motor 33 is connected to the uppermost set of conveyor rollers 25 through a coupling; the forward and reverse motor 33 directly drives the set of conveyor rollers 25 to rotate, thereby driving the overall conveyor belt 26 to rotate in the forward and reverse directions, realizing the functions of feeding and unloading the roll material.

[0047] Please refer to Figure 6 As shown, multiple sets of conveyor rollers 25 are located on the same vertical plane, and multiple sets of mounting shafts 30 are located on the same vertical plane; this ensures that the conveyor belt 26 and the conveyor belt 31 operate smoothly without deviation, and avoids deviation and jamming of the roll material during conveying.

[0048] Please refer to Figure 2 , Figure 5 and Figure 8 As shown, the lower end of the base 10 is fixed with a positioning seat 34 by bolts; the rear end face of the positioning seat 34 is symmetrically fixed with two sets of connecting seats 35 by bolts. The two sets of connecting seats 35 have through slots 36 on their inner sides facing each other. Two sets of connecting screws 37 slide through each set of through slots 36. The position of the connecting screws 37 can be adjusted vertically along the through slots 36; the two sets of connecting screws 37 in the same horizontal position are welded and fixed with mounting rods 38 to realize the linkage adjustment of the connecting screws 37 on the same side; all the connecting screws 37 have washers and connecting nuts 39 movably sleeved on their outer sides. The washers reduce the wear of the connecting nuts 39 when locking; multiple sets of mounting screws 40 are vertically welded to the outer walls of the two sets of mounting rods 38. The scraper 41 is movably sleeved on the outer sides of the multiple sets of mounting screws 40 in the same horizontal position; all the mounting screws 40 have mounting nuts 11 sleeved on their outer sides to lock and fix the position of the scraper 41.

[0049] Please refer to Figure 8As shown, multiple sets of mounting screws 40 and multiple sets of mounting nuts 11 are threaded together; the scraper 41 can be locked and fixed by tightening the mounting nuts 11.

[0050] Please refer to Figure 8 As shown, the four sets of connecting screws 37 and the four sets of connecting nuts 39 are threaded together; tightening the connecting nuts 39 can lock and fix the position of the connecting screws 37, and adjust the working distance of the scraper 41 to accommodate different thicknesses of roll material.

[0051] Please refer to Figure 1 and Figure 2 As shown, an electrical control box is bolted to the end face of the housing 1, and the control box contains a control panel and a battery. The control panel is electrically connected to the battery, two sets of drive motors 4, the first electric telescopic rod 12, the air pump 16, the solenoid valve 18, the servo motor 22, the second electric telescopic rod 27, and the forward and reverse motor 33 via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0052] Please refer to Figure 1 As shown, the output ends of the two sets of drive motors 4 are connected to the two sets of crushing rollers 2 respectively through couplings; the drive motors 4 independently drive the single set of crushing rollers 2 to rotate in opposite directions, and cooperate to complete the initial crushing of the asphalt roll material.

[0053] Please refer to Figure 9 As shown, the main gear 23 and the driven gear 24 mesh with each other; the servo motor 22 drives the main gear 23 to rotate, and through meshing transmission drives the driven gear 24 and the entire crushing barrel 7 to rotate, providing power for the crushing operation of the crushing blades 19 inside the crushing barrel 7.

[0054] Working Principle: This equipment relies on the built-in control panel of the electrical control box to uniformly regulate all electrical components. The base 10 and support columns 9 provide stable support for the entire machine. Before operation, the operator can adjust the position of the connecting screw 37 inside the through groove 36 according to the specifications of the waste asphalt roll and the amount of impurities attached. The vertical spacing between the two sets of connecting screws 37 is adjusted, and the mounting rod 38 is locked in place with the connecting nut 39. The scraper 41 is then disassembled and fixed using the mounting screw 40 and mounting nut 11, suitable for cleaning the bottom surface of the roll. After operation starts, the control panel synchronously starts the forward and reverse motor 33, drive motor 4, and servo motor. Motor 22, air pump 16, and solenoid valve 18, along with reversible motor 33, drive conveyor roller 25 to rotate conveyor belt 26. Conveyor belt 26 and conveyor belt 31 work together to clamp, limit, and move waste asphalt rolls piled on the ground. During the movement of the rolls, the bottom is attached to scraper 41 to remove lumps of cement, large pieces of sand and gravel, and other stubborn impurities from the bottom surface, thus removing hard debris in advance and preventing impurities from entering the crushing mechanism and damaging the components. After the impurities are removed, the waste asphalt rolls enter the box 1 at a uniform speed. Two sets of drive motors 4 drive two sets of crushing rollers 2 to rotate in opposite directions, performing primary crushing and cutting of the rolls. The material after primary crushing... Under gravity, the material falls into the hopper 6. The servo motor 22 drives the main gear 23 to mesh with the driven gear 24, causing the entire crushing barrel 7 to rotate. Multiple sets of crushing blades 19 on the inner wall of the crushing barrel 7 rotate synchronously, performing secondary shearing and fine crushing on the primary crushed material. At the same time, the air pump 16 draws air and delivers it to the air storage plate 14 through the air guide hose 17. The solenoid valve 18 controls the air flow. The first electric telescopic rod 12, in conjunction with the positioning plate and the air storage plate 14, raises and lowers to adjust the air jet height. The one-way nozzle 15 sprays air directionally into the crushing barrel 7. The airflow blows up the asphalt roll powder that has settled at the bottom and accumulated against the wall of the crushing barrel 7, allowing... The powder material fully contacts the crushing blade 19 to complete shearing and crushing, eliminating dead corners in material crushing; the operator can adjust the speed and airflow pressure of each component through the control panel to adapt to the crushing operation of waste asphalt rolls with different aging degrees and different specifications. Finally, the material that meets the standard particle size is discharged from the lower end of the crushing barrel 7, completing the entire set of waste asphalt roll scraper 41 pretreatment and impurity removal, clamping automatic feeding, double-stage crushing, airflow-assisted turning crushing and recycling operation. The entire process is completed in linkage, without the need for high-intensity manual intervention. The clamping feeding is anti-deviation and has strong stability, taking into account both component protection and crushing uniformity, thus improving the overall crushing operation quality.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
