Description

Technical Field

[0001] This invention relates to the field of asphalt recycling technology, and in particular to a waste incineration ash modified asphalt pavement paving machine with a recycling structure. Background Technology

[0002] With the continuous acceleration of urbanization and sustained investment in infrastructure construction, a large number of asphalt pavements are entering the maintenance or reconstruction cycle, generating a huge amount of waste asphalt mixtures. At the same time, the treatment and resource utilization of incineration ash generated from the incineration of municipal solid waste has also become an environmental problem that urgently needs to be solved. Using waste incineration ash as a modifier in the recycling of asphalt mixtures can realize the resource utilization of solid waste and reduce the environmental burden. In the field of asphalt pavement recycling technology, it is usually necessary to crush, screen, heat, and remix the recycled waste asphalt mixture with new aggregates, new asphalt, or modifiers before it can be used for pavement paving.

[0003] However, in existing technical solutions, when recycling asphalt mixtures at room temperature, it is usually necessary to rapidly heat them to reach the working temperature. This process is often accompanied by high energy consumption, and since asphalt materials are sensitive to temperature, drastic temperature changes may cause them to age, affecting the final performance of the recycled mixture.

[0004] In view of this, this paper studies and improves upon existing problems, and provides a waste incineration ash modified asphalt pavement paving machine with a recycling structure. The aim is to solve the problems and improve the practical value through this technology. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a waste incineration ash modified asphalt pavement paving machine with a recycling structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waste incineration ash modified asphalt pavement paver with a recycling structure, comprising a machine body, a screening box installed at the top of the machine body, a crushing chamber fixed at the top of the screening box, a hot air blower installed on the side wall of the crushing chamber, an air supply pipe connected to the output end of the hot air blower, an electric heating plate installed on the inner wall of the crushing chamber, a rotating shaft A rotating inside the crushing chamber, and a crushing roller installed on the outer wall of the rotating shaft A; The screening box is equipped with a crushing mechanism inside. The crushing mechanism includes a frame plate that slides inside the screening box. The frame plate is fixed with mounting plates that are evenly spaced inside. The surface of the mounting plates is embedded with conical balls. The side wall of the screening box is fixed with a shell. The inner wall of the shell is rotatably connected with a rotating shaft B. A cam is installed at one end of the rotating shaft B. The side wall of the frame plate is fixed with a connecting rod. A swing arm is hinged between the cam and the connecting rod. A screening mechanism is provided below the frame plate. The screening mechanism includes a screening plate that slides inside the screening box. Two sets of symmetrical fixing plates are fixed on the inner wall of the screening box. Multiple sets of symmetrical stirring rods rotate between the two sets of fixing plates. A hinge seat is installed on the surface of the screening plate. A pull plate is hinged between the hinge seat and the stirring rod. The bottom end of the screening plate is equipped with a shearing mechanism.

[0007] Preferably, the outer walls of both the rotating shaft A and the rotating shaft B are fitted with rotating wheels, and the two sets of rotating wheels are connected by a belt drive.

[0008] Preferably, the side wall of the screening box is provided with a first sliding groove, and the connecting rod slides along the vertical direction of the first sliding groove.

[0009] Preferably, a spring rod is installed inside the housing, and a side plate located below the cam is fixed to the side wall of the screening plate, with the bottom end of the side plate fixedly connected to the top end of the spring rod.

[0010] Preferably, the side wall of the screening box is equipped with a second sliding groove, and the side plate slides along the vertical direction of the first sliding groove.

[0011] Preferably, a gear is installed at one end of the stirring rod, and a slot is provided on the side wall of one of the fixing plates, the gear is located inside the slot, and the top of the slot is provided with teeth that mesh with the gear.

[0012] Preferably, the shearing mechanism includes two sets of sliding plates that slide on the bottom of the screening plate. The two sets of sliding plates are symmetrically distributed about the central axis of the screening plate. Multiple sets of shearing plates with equal spacing are installed between the two sets of sliding plates. A guide groove is provided on the side wall of the screening box. A guide block is fixed on the side wall of the sliding plate. The guide block slides along the inside of the guide groove.

[0013] Preferably, the bottom end of the screening plate is provided with a limiting groove, and the top end of the slide plate is fixed with a slider, which slides inside the limiting groove.

[0014] Preferably, the slide plate is arranged in an inverted triangle shape, and the top of the slide plate slides back and forth against the bottom of the screening plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a hot air blower to deliver hot air into the crushing chamber through an air pipe. This preheats the asphalt inside the crushing chamber and powers the heating plate, making the temperature inside the screening box higher than that inside the crushing chamber. The temperature inside the crushing chamber softens the asphalt waste, while the temperature inside the screening box further softens the asphalt, reducing agglomeration caused by asphalt adhesion between particles. This results in a more uniform particle size distribution and a more even and gentle heating process for the asphalt, thus avoiding rapid heating that could lead to asphalt aging and ensuring the quality of asphalt recycling.

[0016] 2. This invention uses a cam protrusion to periodically push the side plate of the screening plate downwards, which, combined with a spring rod for resetting, achieves vibratory screening of the screening plate. When the screening plate moves downwards, the hinged seat pulls two sets of stirring rods closer together via a pull plate, gathering large asphalt particles and cooperating with the conical ball to complete secondary crushing. This effectively solves the problems of uneven asphalt crushing and large particle residue in traditional equipment, ensuring that the processed asphalt particles have a consistent particle size and are evenly dispersed. This provides a high-quality material guarantee for subsequent mixing and modification of asphalt with waste incineration ash and for road paving construction, improving the smoothness and structural strength of the paved road surface. At the same time, during the movement of the two sets of stirring rods closer together, the stirring rods rotate while moving horizontally, which can fully stir the asphalt material on the surface of the screening plate and separate the evenly crushed small asphalt particles from the incompletely crushed large asphalt particles, further improving the dispersibility of the asphalt material. In addition, the asphalt crushed by stirring is more easily heated evenly, further improving the heating effect.

[0017] 3. This invention uses a screening plate to drive a sliding plate to move synchronously downwards. The sliding plate slides along the inside of the guide groove, causing it to reciprocate along the bottom of the screening plate. This, in turn, drives multiple shearing plates installed between the two sets of sliding plates to reciprocate synchronously. The shearing action directly cuts the asphalt adhesion between agglomerated particles, dispersing the originally clumped mixture into single particles with uniform particle size. This effectively solves the problem of particle agglomeration that still exists after initial crushing and screening, further improving the uniformity of the asphalt mixture. At the same time, for some stubborn clogged particles that are stuck in the screen holes of the screening plate and cannot be removed by the vibration of the screening plate alone, the shearing force generated by the shearing plate during the reciprocating movement can remove them from the screen holes by cutting and peeling them off, thus clearing the screen holes and avoiding the problems of reduced screening efficiency and material accumulation caused by screen hole blockage in traditional screening equipment.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] See Figures 1 to 9 As shown, the present invention provides a waste incineration ash modified asphalt pavement paving machine with a recycling structure, including a machine body 1, a screening box 2 installed at the top of the machine body 1, a crushing chamber 3 fixed at the top of the screening box 2, a hot air blower 4 installed on the side wall of the crushing chamber 3, an air supply pipe connected to the output end of the hot air blower 4, an electric heating plate 7 installed on the inner wall of the crushing chamber 3, a rotating shaft A5 rotating inside the crushing chamber 3, and a crushing roller 6 installed on the outer wall of the rotating shaft A5. It should be noted that when asphalt needs to be recycled, the hot air blower 4 is started before the asphalt enters the crushing chamber 3. The hot air blower 4 generates hot air and introduces it into the crushing chamber 3 through the air pipe, so that the hot air inside the crushing chamber 3 preheats the asphalt. The electric heating plate 7 is energized, so that the temperature inside the screening box 2 is higher than the temperature inside the crushing chamber 3. The temperature inside the crushing chamber 3 can make the asphalt waste relatively soft, while the temperature inside the screening box 2 promotes further softening of the asphalt, reducing the agglomeration caused by asphalt adhesion between particles, making the particle size distribution of each grade of particles more uniform, and making the heating process of the asphalt more uniform and gentle. This avoids the asphalt aging caused by rapid heating and ensures the quality of asphalt recycling.

[0022] The screening box 2 is equipped with a crushing mechanism, which includes a frame plate 81 that slides inside the screening box 2. The frame plate 81 is fixed with equally spaced mounting plates 82. The surface of the mounting plates 82 is embedded with conical balls 83. The side wall of the screening box 2 is fixed with a housing 88. The inner wall of the housing 88 is rotated with a rotating shaft B84. One end of the rotating shaft B84 is equipped with a cam 85. The side wall of the frame plate 81 is fixed with a connecting rod 86. A swing rod 87 is hinged between the cam 85 and the connecting rod 86. A screening mechanism is provided below the frame plate 81. The screening mechanism includes a screening plate 91 that slides inside the screening box 2. Two sets of symmetrical fixing plates 94 are fixed on the inner wall of the screening box 2. Multiple sets of symmetrical stirring rods 97 rotate between the two sets of fixing plates 94. A hinge seat 95 is installed on the surface of the screening plate 91. A pull plate 96 is hinged between the hinge seat 95 and the stirring rod 97. It should be noted that when processing recycled asphalt, two sets of motors are started, and the output ends of the motors synchronously drive the two sets of rotating shafts A5 in the crushing chamber 3 to rotate, causing the two sets of rotating shafts A5 to drive the corresponding crushing rollers 6 to rotate in opposite directions. When the asphalt material falls between the two sets of crushing rollers 6, the crushing rollers 6 rotating in opposite directions form shearing and extrusion forces, completing the initial crushing process of the asphalt. The initially crushed asphalt material falls naturally onto the surface of the screening plate 91 inside the screening box 2. Simultaneously, the rotating shaft A5 rotates, and the rotating wheel fitted on its outer wall drives the rotating shaft B84 inside the side wall shell 88 of the screening box 2 to rotate synchronously via the transmission action of the belt. This causes the cam 85 at the drive end of the rotating shaft B84 to begin rotating counterclockwise. Since the cam 85 is hinged to the connecting rod 86 on the side wall of the frame plate 81 via the rocker arm 87, the rotation of the cam 85 generates a pushing and pulling force on the connecting rod 86 through the rocker arm 87, causing the connecting rod 86 to rotate counterclockwise. The cam 86 moves up and down along the first slide groove on the side wall of the screening box 2. Simultaneously, the connecting rod 86 drives the connected frame plate 81 and the multiple sets of conical balls 83 fixed inside the frame plate 81 to move up and down. As the cam 85 rotates counterclockwise, its structural characteristics cause the protruding end to periodically contact the surface of the side plate 92 on the side wall of the screening plate 91. When the protruding end of the cam 85 rotates downwards, it exerts a downward thrust on the side plate 92, pushing it down along the second slide groove of the screening box 2. The side plate 92 then drives the screening plate 91, which is fixed to it, to move downwards simultaneously. The cam 85 rotates away from the side plate 92, and under the elastic reset action of the spring rod 93, the side plate 92 and the screening plate 91 will move upward again, so that the screening plate 91 can realize the up-and-down reciprocating vibration screening action. When the screening plate 91 moves downward, the hinge seat 95 mounted on its surface moves downward accordingly. Since the hinge seat 95 is hinged to two sets of symmetrically arranged stirring rods 97 through the pull plate 96, the downward movement of the hinge seat 95 will generate a pulling force on the stirring rods 97 through the pull plate 96, causing the two sets of stirring rods 97 to move closer to each other. During this process, the stirring rods 97 can... The larger asphalt particles on the surface of the screening plate 91 are intercepted and gathered to the top of the plate. At this time, the plate 91 works in conjunction with the cone ball 83 that moves down synchronously. The cone ball 83 impacts and crushes the gathered large asphalt particles, completing the secondary refinement of the asphalt. This effectively solves the problems of uneven asphalt crushing and large particle residue in traditional equipment, ensuring that the processed asphalt particles have a consistent particle size and are evenly dispersed. This provides a high-quality material guarantee for the subsequent mixing and modification of asphalt and waste incineration ash, as well as for road paving construction, and improves the smoothness and structural strength of the paved road. Meanwhile, as the two sets of stirring rods 97 move closer to each other, the gear 98 installed at one end of the rod will mesh with the teeth at the top of the slot of the fixed plate 94. The meshing action of the gear 98 causes the stirring rod 97 to rotate while moving horizontally. The rotating stirring rod 97 can not only fully stir the asphalt material on the surface of the screening plate 91, but also separate the uniformly crushed small particles of asphalt from the incompletely crushed large particles of asphalt, further improving the dispersibility of the asphalt material. At the same time, the asphalt that is stirred and crushed by the stirring rod 97 is more easily heated evenly, further improving the heating effect.

[0023] The bottom end of the screening plate 91 is equipped with a shearing mechanism.

[0024] In an optional embodiment: both the outer walls of the rotating shaft A5 and the rotating shaft B84 are fitted with rotating wheels, and the two sets of rotating wheels are connected by a belt drive. The power of the rotating shaft A5 can synchronously drive the rotating shaft B84 to rotate, eliminating the need to configure a separate drive device for the rotating shaft B84. This simplifies the structure of the equipment's power system, reduces energy consumption and manufacturing costs, and ensures the synchronicity of the crushing operation of the crushing roller 6 driven by the rotating shaft A5 and the subsequent crushing, screening and shearing mechanism driven by the rotating shaft B84 and the cam 85.

[0025] In an optional embodiment: a first groove is provided on the side wall of the screening box 2, and the connecting rod 86 slides along the vertical direction of the first groove, limiting the connecting rod 86 to slide only in the vertical direction.

[0026] In an optional embodiment: a spring rod 93 is installed inside the housing 88, and a side plate 92 located below the cam 85 is fixed to the side wall of the screening plate 91. The bottom end of the side plate 92 is fixedly connected to the top end of the spring rod 93, and the spring rod 93 provides an elastic restoring force to the screening plate 91.

[0027] In an optional embodiment: a second slide groove is installed on the side wall of the screening box 2, and the side plate 92 slides along the vertical direction of the first slide groove, limiting the side plate 92 to slide only in the vertical direction.

[0028] In an optional embodiment: a gear 98 is installed at one end of the stirring rod 97, and a slot is provided on the side wall of one of the fixing plates 94. The gear 98 is located inside the slot, and the top of the slot is provided with teeth that mesh with the gear 98. The gear 98 meshes with the teeth of the slot to drive the stirring rod 97 to rotate while translating, which not only enhances the stirring and dispersing effect on the asphalt material, but also more fully gathers large particles of asphalt into the cone sphere 83.

[0029] In an optional embodiment: the shearing mechanism includes two sets of sliding plates 101 that slide on the bottom of the screening plate 91. The two sets of sliding plates 101 are symmetrically distributed about the central axis of the screening plate 91. Multiple sets of shearing plates 102 are installed between the two sets of sliding plates 101. The side wall of the screening box 2 is provided with a guide groove 104. A guide block is fixed to the side wall of the sliding plate 101. The guide block slides along the inside of the guide groove 104.

[0030] In an optional embodiment: a limiting groove 103 is provided at the bottom end of the screening plate 91, and a slider is fixed at the top end of the slide plate 101. The slider slides inside the limiting groove 103 to ensure that the slide plate 101 always moves in contact with the bottom end of the screening plate 91 and avoids deviation and separation.

[0031] In an optional embodiment, the slide plate 101 is arranged in an inverted triangle shape, and the top of the slide plate 101 slides back and forth against the bottom of the screening plate 91.

[0032] It should be noted that when the protruding end of the cam 85 rotates downward and pushes the side plate 92 downward, the side plate 92 simultaneously drives the screening plate 91 to move downward. The two sets of sliding plates 101, connected to the bottom of the screening plate 91 via the limiting groove 103 and the slider, will move synchronously with the downward movement of the screening plate 91. During this process, the guide block fixed to the side wall of the sliding plate 101 will slide along the guide groove 104 opened on the side wall of the screening box 2. The structural design of the guide groove 104 allows the sliding plate 101 to move up and down with the screening plate 91 while also reciprocating along the bottom of the screening plate 91. This, in turn, drives the multiple sets of shearing plates 102 installed between the two sets of sliding plates 101 to simultaneously complete the reciprocating movement. When the shearing plates 102 reciprocate along the bottom of the screening plate 91, their... The blade-like edge performs secondary shearing and crushing on the small pieces of mixture that have just passed through the screen holes of the screening plate 91 and fallen below. The shearing action can directly cut off the asphalt adhesion between agglomerated particles, dispersing the originally clumped mixture into single particles with uniform particle size. This effectively solves the problem of particle agglomeration that still exists after initial crushing and screening, further improving the uniformity of the asphalt mixture. At the same time, for some stubborn clogged particles that are stuck in the screen holes of the screening plate 91 and cannot be removed by the vibration of the screening plate 91 alone, the shearing force generated by the reciprocating movement of the shearing plate 102 can remove them from the screen holes by cutting and peeling them off, thus clearing the screen holes and avoiding the problems of reduced screening efficiency and material accumulation caused by screen hole blockage in traditional screening equipment.

[0033] Working principle: When asphalt needs to be recycled, before the asphalt enters the crushing chamber 3, the hot air blower 4 is started. The hot air blower 4 generates hot air and sends it into the crushing chamber 3 through the air pipe, so that the hot air inside the crushing chamber 3 preheats the asphalt. The electric heating plate 7 is energized, so that the temperature inside the screening box 2 is higher than the temperature inside the crushing chamber 3. The temperature of the crushing chamber 3 can make the asphalt waste relatively soft. When processing recycled asphalt, two sets of motors are started, and the output of the motors synchronously drives the two sets of rotating shafts A5 in the crushing chamber 3 to rotate. This causes the two sets of rotating shafts A5 to drive the corresponding crushing rollers 6 to rotate in opposite directions. When the asphalt material falls between the two sets of crushing rollers 6, the crushing rollers 6 rotating in opposite directions form shearing and extrusion forces, completing the initial crushing process of the asphalt. The initially crushed asphalt material falls naturally onto the surface of the screening plate 91 inside the screening box 2. Simultaneously, the rotating shaft A5 rotates, and the rotating wheel fitted on its outer wall drives the rotating shaft B84 inside the side wall shell 88 of the screening box 2 to rotate synchronously via a belt drive. This causes the cam 85 at the drive end of the rotating shaft B84 to begin rotating counterclockwise. Since the cam 85 is hinged to the connecting rod 86 on the side wall of the frame plate 81 via the rocker arm 87, the rotation of the cam 85 generates a pushing and pulling force on the connecting rod 86 through the rocker arm 87, causing the connecting rod 86 to move up and down along the first sliding groove on the side wall of the screening box 2. The connecting rod 86 then synchronously drives the frame plate 81 it connects to and the multiple sets of conical balls 83 fixed inside the frame plate 81 to move up and down synchronously. During the continuous counterclockwise rotation of the cam 85, its structural characteristics... This causes the protruding end to periodically contact the surface of the side plate 92 on the side wall of the screening plate 91. When the protruding end of the cam 85 rotates to the lower position, it will exert a downward thrust on the side plate 92, pushing the side plate 92 down along the second slide groove of the screening box 2. The side plate 92 will then drive the screening plate 91 fixed thereto to move down synchronously. When the protruding end of the cam 85 rotates away from the side plate 92, under the elastic reset action of the spring rod 93, the side plate 92 and the screening plate 91 will move back up, so that the screening plate 91 can realize the up-and-down reciprocating vibration screening action. When the screening plate 91 moves down, the hinge seat 95 installed on its surface moves down accordingly. Since the hinge seat 95 is hinged to two sets of symmetrically arranged stirring rods 97 through the pull plate 96, the downward movement of the hinge seat 95 will generate a pulling force on the stirring rods 97 through the pull plate 96, causing the two sets of stirring rods 97 to move closer to each other. Meanwhile, as the two sets of stirring rods 97 move closer to each other, the gear 98 installed at one end of them will mesh with the teeth at the top of the slot of the fixed plate 94. The meshing action of the gear 98 causes the stirring rod 97 to rotate while it is translating. When the protruding end of the cam 85 rotates downward and pushes the side plate 92 to move down, the side plate 92 simultaneously drives the screening plate 91 to move downward. The two sets of sliding plates 101 connected to the bottom of the screening plate 91 through the limiting groove 103 and the slider will move synchronously with the downward movement of the screening plate 91. During this process, the guide block fixed on the side wall of the sliding plate 101 will slide along the guide groove 104 opened on the side wall of the screening box 2. The structural design of the guide groove 104 makes the sliding plate 101 move up and down with the screening plate 91, and at the same time, it will also move back and forth along the bottom of the screening plate 91, thereby driving the multiple sets of shearing plates 102 installed between the two sets of sliding plates 101 to complete the reciprocating movement synchronously. When the shearing plate 102 moves back and forth along the bottom of the screening plate 91, its blade-shaped edge will perform secondary shearing and crushing on the small pieces of mixed material that have just passed through the screen holes of the screening plate 91 and fallen to the bottom.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
