Description

The storage module, the primary screening module, the stripping and crushing module, and the secondary screening module are integrally connected, and the particle size of the asphalt concrete screened by the primary screening module and the secondary screening module decreases in turn. The asphalt concrete recycling material is quickly dispersed by the stripping and crushing module, and part of the asphalt on the surface of the asphalt concrete recycling material is stripped off, thereby realizing aggregate crushing of the asphalt concrete recycling material and reducing the agglomeration rate of the asphalt concrete recycling material. However, it is found that the crushing method is extensive and has poor adaptability during long-term use. Once the crushing cavity structure and working parameters of the crusher are set, they are difficult to change. For asphalt concrete blocks of different particle sizes, the "one-size-fits-all" crushing method is used, which easily leads to insufficient crushing or equipment overload. SUMMARY

DETAILED DESCRIPTION

[0038] The application will be further described in conjunction with the drawings and specific embodiments.

[0039] With reference to Figures 1 to 14 The embodiment provides a recycled asphalt concrete recycling system for recycling asphalt concrete blocks, which comprises a control module and an input conveying module, a visual recognition module and a self-adaptive stripping and crushing module arranged in sequence along the conveying direction of the asphalt concrete blocks.

[0040] The input conveying module comprises a screening device 1, a first conveying belt 2 and a conveying belt 21, the screening device 1 is preferably a grizzly screen, the recycled asphalt concrete blocks pass through the screening device 1, the asphalt concrete blocks smaller than the maximum screening size of the screening device 1 are screened as common asphalt concrete blocks, and the remaining super-large asphalt concrete blocks on the screening device 1 are conveyed through the first conveying belt 2, and the common asphalt concrete blocks are output through the conveying belt 21;

[0041] The visual recognition module is installed above the conveying belt 21 in the input conveying module, is used for collecting image information of the common asphalt concrete blocks on the conveying belt 21 in real time and non-contact, and analyzes characteristic data of the common asphalt concrete blocks through an image processing technology, wherein the characteristic data comprises a particle size distribution of the common asphalt concrete blocks.

[0042] The self-adaptive stripping and crushing module receives the common asphalt concrete blocks conveyed by the conveying belt 21, and crushes the input common asphalt concrete blocks, specifically adjusts the interval between the first crushing roller 102 and the second crushing roller 104 to crush the common asphalt concrete blocks.

[0043] The control module is electrically connected with the visual recognition module and the self-adaptive stripping and crushing module, is used for receiving the characteristic data output by the visual recognition module, and calculates optimal crushing parameters of the current self-adaptive stripping and crushing module in real time according to a preset control algorithm or a database, and automatically adjusts the self-adaptive stripping and crushing module to the optimal crushing parameters, namely the interval between the first crushing roller 102 and the second crushing roller 104 and the rotating speed of the crushing motor 112, and then sends a control instruction to the crushing motor 112 and the driving cylinder 105 in the self-adaptive stripping and crushing module, so as to complete the automatic adjustment of the optimal crushing parameters.

[0044] The visual recognition module preferably adopts a near-infrared hyperspectral imager, which scans the ordinary asphalt concrete blocks on the conveying belt 21. Different functional groups in asphalt (such as carbonyl C=O and sulfoxide S=O) have characteristic absorption peaks in the near-infrared spectral region (900-1700 nm). Further, by analyzing the intensity and position of the absorption peaks, a chemometrics model can be established to real-time invert the aging index (such as carbonyl index and sulfoxide index) of the old asphalt and the asphalt content. The aging index and the asphalt content can also be used as characteristic data, which are received by the control module to control the optimal distance between the first crushing roller 102 and the second crushing roller 104 and the optimal rotating speed of the crushing motor 112.

[0045] The self-adaptive stripping and crushing module includes a crushing frame 101, a first crushing roller 102 rotatably arranged on one side of the crushing frame 101, a moving plate 103 slidably arranged on the other side of the crushing frame 101, a second crushing roller 104 rotatably arranged on the top of the moving plate 103, a drive cylinder 105 for driving the moving plate 103 to move laterally, a fixed shell 106 arranged on both sides of the crushing frame 101 in front of and behind the first crushing roller 102 and on the left side of the crushing frame 101, a right side shell 107 arranged on the right side of the moving plate 103, a discharge port 108 arranged at the bottom of the crushing frame 101, a first face gear 109 arranged at the front end of the first crushing roller 102, a second face gear 110 arranged at the front end of the second crushing roller 104, a drive gear 111 rotatably arranged on the crushing frame 101 and meshing with the first face gear 109 and the second face gear 110, and a crushing motor 112 for rotating the drive gear 111. The width of the drive gear 111 is greater than the interval distance between the first face gear 109 and the second face gear 110, and the second face gear 110 can move laterally on the drive gear 111.

[0046] The crushing motor 112 rotates the drive gear 111, which rotates the first face gear 109 and the second face gear 110 at the same time, and the first face gear 109 and the second face gear 110 rotate the first crushing roller 102 and the second crushing roller 104. The ordinary asphalt concrete blocks poured into the crushing frame 101 are crushed by the first crushing roller 102 and the second crushing roller 104. When the control module needs to control the distance between the first crushing roller 102 and the second crushing roller 104, the drive cylinder 105 drives the moving plate 103 to move laterally, and the moving plate 103 drives the second crushing roller 104 and the second face gear 110 to move when it moves laterally. The second face gear 110 can be in contact with the drive gear 111 in real time, so that the distance between the first crushing roller 102 and the second crushing roller 104 can be adjusted in real time according to the ordinary asphalt concrete blocks.

[0047] The right side shell 107 is located between the front and rear of the fixed shell 106, and during the movement of the moving plate 103, the right side shell 107 will be moved between the fixed shell 106, which can keep the first crushing roller 102 and the second crushing roller 104 closed without affecting the movement of the right side shell 107 and the second crushing roller 104.

[0048] The first crushing roller 102 is provided with a plurality of trapezoidal protruding blocks 113 on the outside, the trapezoidal protruding blocks 113 are wide at the bottom and narrow at the top, the trapezoidal protruding blocks 113 are provided with abrasive plates 114 on the top, the abrasive plates 114 are arc-shaped away from one side of the trapezoidal protruding blocks 113, the inside of the first crushing roller 102 between the trapezoidal protruding blocks 113 is provided with an embedded plate 115, the embedded plate 115 is provided with a recess 116 in the middle, the embedded plate 115 is provided with stepped holes 117 on the left and right sides, the stepped holes 117 of the embedded plate 115 are provided with fasteners 118 matched with the first crushing roller 102, springs 119 are arranged between the embedded plate 115 and the stepped holes 117, and the first crushing roller 102 and the second crushing roller 104 are the same in structure.

[0049] During the rotation of the first crushing roller 102 and the second crushing roller 104, the abrasive plates 114 on the trapezoidal protruding blocks 113 are close to the embedded plate 115, and because the embedded plate 115 has a recess 116, the abrasive plates 114 and the recess 116 will crush ordinary asphalt concrete blocks. Because the trapezoidal protruding blocks 113 are protruding at the tip, the part directly contacts the ordinary asphalt concrete blocks and wears out quickly during actual use, and the abrasive plates 114 can delay the wear time, the arc-shaped abrasive plates 114 wear more evenly and have stronger fatigue resistance. When used with the embedded plate 115, the embedded plate 115 is connected with the first crushing roller 102 through the fasteners 118 and the springs 119, the rotation depth of the fasteners 118 can be controlled, the interval distance between the stepped holes 117 and the fasteners 118 can be adjusted, the embedded plate 115 is pushed up by the spring 119, and the embedded plate 115 is moved downward under the force of the spring 119. When the abrasive plates 114 and the embedded plate 115 crush ordinary asphalt concrete blocks, the embedded plate 115 is moved downward under the force of the spring 119, some ordinary asphalt concrete blocks can be buffered and crushed by the spring 119, and some ordinary asphalt concrete blocks with low coagulation are crushed.

[0050] The feed conveying module of the asphalt concrete recycling system also has a device for processing oversized asphalt concrete blocks output by the first conveying belt 2, which can be specifically referred to Figures 8-14, including a pre-crushing frame 3 arranged below the first conveying belt 2, a first crushing roller 4 rotatably arranged on the top of the pre-crushing frame 3 and arranged along the z-axis direction of the pre-crushing frame 3, a horizontal baffle plate 5 arranged on the top of the pre-crushing frame 3, a middle groove 6 arranged on the horizontal baffle plate 5, a guide plate 7 arranged on the top of the pre-crushing frame 3, a fixed roller 8 arranged on the horizontal baffle plate 5 at the position of the middle groove 6 and arranged in a staggered manner with the first crushing roller 4, a second crushing roller 9 rotatably arranged on the middle of the pre-crushing frame 3 and arranged along the x-axis direction of the pre-crushing frame 3, a second baffle plate 10 arranged on the top of the pre-crushing frame 3 and below the second crushing roller 9, a second horizontal hole 11 arranged on the second baffle plate 10 and used for the second crushing roller 9 to pass through, a first driving device (not shown in the figure) used for driving the first crushing roller 4 to rotate, a second conveying belt 12 arranged below the second baffle plate 10, and a synchronization mechanism 14 used for synchronizing the rotation of the second crushing roller 9.

[0051] The screening device 1 conveys the oversized asphalt concrete blocks into the pre-crushing frame 3 through the first conveying belt 2, the first driving device drives the first crushing roller 4 and the second crushing roller 9 to rotate, when the oversized asphalt concrete blocks fall into the top of the pre-crushing frame 3, the oversized asphalt concrete blocks in the pre-crushing frame 3 are in contact with the fixed roller 8 on the horizontal baffle plate 5 along with the rotation of the first crushing roller 4, after the first crushing roller 4 passes through the fixed roller 8 on the horizontal baffle plate 5, the oversized asphalt concrete blocks are crushed and fall down by being extruded by the first crushing roller 4 and the fixed roller 8, the first crushing roller 4 is arranged in the z-axis direction, which crushes the oversized asphalt concrete blocks, part of the horizontal asphalt concrete blocks without being crushed will also fall down to the position outside the second crushing roller 9 and be crushed by the second crushing roller 9 and the second baffle plate 10. The crushed oversized asphalt concrete blocks will fall through the second horizontal hole 11 of the second baffle plate 10 to the second conveying belt 12 at the bottom, which pre-crushes the oversized asphalt concrete blocks into pieces, avoiding the slow crushing speed of the oversized asphalt concrete blocks when they fall into the jaw crusher for primary crushing.

[0052] The first crushing roller 4 is provided with external rollers (not marked in the figure) distributed in a spiral shape from top to bottom, if the external rollers of the first crushing roller 4 are distributed in a circumferential array, the falling oversized asphalt concrete blocks are easy to be stuck above the first crushing roller 4 and easy to fall down to the position of the second crushing roller 9 without being crushed by the first crushing roller 4, the oversized asphalt concrete blocks will be inclined and attached to the outside of the first crushing roller 4, and the oversized asphalt concrete blocks will be crushed by being extruded by the first crushing roller 4 and the fixed roller 8 along with the rotation of the first crushing roller 4.

[0053] The first driving device comprises a driving frame 1301 arranged in the front crushing frame 3, a first gear shaft 1302 arranged on the top surface of the driving frame 1301 and located in the z-axis direction, a second gear shaft 1303 arranged in the middle of the driving frame 1301 and located in the x-axis direction, and a crushing motor 1304 for driving the first gear shaft 1302 to rotate, the first gear shaft 1302 is engaged with the second gear shaft 1303, the first crushing rod 4 is arranged on the top surface of the first gear shaft 1302, and the synchronous mechanism 14 can be a chain transmission mechanism, when the first gear shaft 1302 rotates, the second gear shaft 1303 is driven to rotate by the synchronous mechanism 14, and other existing mechanisms can also be replaced, which are prior art and will not be described here.

[0054] The crushing motor 1304 drives the first gear shaft 1302 to rotate, the first gear shaft 1302 drives the first crushing rod 4 and the top surface second gear shaft 1303 to rotate, the second gear shaft 1303 drives the second crushing rod 9 to rotate through the synchronous mechanism 14, and the first crushing rod 4 and the second crushing rod 9 can be driven to rotate synchronously, and the first crushing rod 4 and the second crushing rod 9 can be driven to rotate by the single crushing motor 1304.

[0056] The inclined pipe 301 is arranged inside the front crushing frame 3 close to the position of the second crushing rod 9, and the included angle between the inclined pipe 301 and the front crushing frame 3 is 70°-80°.

[0057] Part of the uncrushed oversized asphalt concrete block will be driven upward by the second crushing rod 9, and will be crushed again through the inclined pipe 301, and since the inclined pipe 301 is downwardly inclined, the oversized asphalt concrete block will fall again to the second baffle 10 after being crushed.

[0058] The driving frame 1301 is located above the top surface of the first rubbing roller 4 and is provided with a rotating shaft 1305. One side of the rotating shaft 1305 is provided with a cross block 1306. The top surface of the first rubbing roller 4 is provided with a protrusion 401. The transversely two side ends of the cross block 1306 are provided with protruding columns 1307 which are in contact with the protrusion 401 to rotate the rotating shaft 1305. The other side of the rotating shaft 1305 is provided with a swing arm 1308. The outer side of the swing arm 1308 is provided with a side frame 1317. The side frame 1317 is located at the bottom of the swing arm 1308 and is provided with a longitudinally slidable adjusting sliding block 1309. The bottom of the swing arm 1308 is provided with an arm sliding block 1310 which is in sliding connection. An elastic member 1311 is arranged between the arm sliding block 1310 and the swing arm 1308. A connecting rod 1312 is in rotational connection between the arm sliding block 1310 and the adjusting sliding block 1309. The bottom of the driving frame 1301 is provided with an adjusting lead screw 1313 for driving the adjusting sliding block 1309 to move longitudinally.

The material cleaning plate 1314 is provided with third transverse holes 1315 which are arranged at the same positions as the second transverse holes 11. The material cleaning plate 1314 is provided with triangular blocks 1316 between adjacent third transverse holes 1315. When it is needed to control the swing distance of the swing arm 1308, the adjusting lead screw 1313 is rotated. The adjusting lead screw drives the connecting rod 1312 to move downward through the adjusting sliding block 1309, so as to reduce the swing distance of the swing arm 1308. In actual use, the width of the third transverse holes 1315 can be adjusted.

[0059] When the second crushing roller 9 rotates, the protrusion 401 will contact the protrusion column 1307 on one side of the cross block 1306. After the cross block 1306 is contacted for the first time, the side will be raised and drive the rotating shaft 1305 to rotate, and the rotating shaft 1305 drives the swing arm 1308 to rotate by a distance. The swing arm 1308 drives the cleaning plate 1314 to move by a distance, which is the interval distance between the third horizontal holes 1315. The cleaning plate 1314 moves to the position of the third horizontal holes 1315. At this time, the smooth surface of the second crushing roller 9 will face the position of the third horizontal holes 1315. The super large asphalt concrete block vertically on the second crushing roller 9 will fall and be placed flat on the top surface of the second baffle 10. As the second crushing roller 9 continues to rotate, the protrusion 401 will contact the protrusion column 1307 on the other side of the cross block 1306. The cross block 1306 is raised again in the opposite direction and drives the rotating shaft 1305 to rotate to the original position. The rotating shaft 1305 drives the cleaning plate 1314 to move to the original position through the swing arm 1308, without shielding the position of the second horizontal holes 11. The roller surface of the second crushing roller 9 moves to the position of the second baffle 10 (the second crushing roller 9 has a roller surface and a smooth surface. The roller surface refers to the part of the second crushing roller 9 outside with a roller shape. The smooth surface refers to the part of the second crushing roller 9 outside without a roller shape). The super large asphalt concrete block on the second baffle 10 is crushed. The cleaning plate 1314 can clean the super large asphalt concrete block remaining in the gap between the second horizontal holes 11 on the second baffle 10. As the smooth surface of the second crushing roller 9 moves to the second baffle 10, it can shield the position of the second horizontal holes 11, avoiding the super large asphalt concrete block stuck on the roller surface of the second crushing roller 9 from sliding off the second horizontal holes 11. The fallen super large asphalt concrete block will reattach to the top surface of the cleaning plate 1314 due to gravity. As the cleaning plate 1314 moves back to the original position, the second crushing roller 9 will pass through the third horizontal holes 1315 and the second horizontal holes 11 to crush the super large asphalt concrete block, further improving the crushing effect.

[0060] A method for recycling reclaimed material by an asphalt concrete reclaimed material recycling system, comprising the following steps:

[0061] In the first step, the feed conveying module connects the externally input asphalt concrete block. The asphalt concrete block passes through the grid sieve. The asphalt concrete block smaller than the maximum screening size of the screening device 1 is screened as a common asphalt concrete block. The remaining super large asphalt concrete block on the screening device 1 is output through the first conveying belt 2. The common asphalt concrete block is conveyed to the self-adaptive stripping and crushing module through the conveying belt 21.

[0062] In the second step, the visual recognition module recognizes the common asphalt concrete block passing through the conveying belt 21. The image information of the common asphalt concrete block on the conveying belt 21 is collected in real time and non-contact. The particle size distribution of the common asphalt concrete block is analyzed through image processing technology.

[0063] In the third step, the control module receives the common asphalt concrete block feature data from the visual recognition module, and calculates the optimal breaking parameters of the current self-adaptive stripping and breaking module according to the preset control algorithm or database, and automatically adjusts the self-adaptive stripping and breaking module to the current optimal breaking parameters, wherein the optimal breaking parameters include the distance between the first breaking roller 102 and the second breaking roller 104, and the rotating speed of the breaking motor 112.
