Description

Technical Field

[0001] The invention relates to the technical field of modified asphalt processing, and in particular to a modified asphalt processing device and method. Background Art

[0002] Modified asphalt is a new type of building material that improves the performance of asphalt by adding modifiers such as rubber, resin or high molecular polymer to the base asphalt. Modified asphalt usually uses base asphalt and modifier as raw materials during processing. First, the base asphalt is heated to a certain temperature, and then the ground modifier is added to the base asphalt. The base asphalt is continuously stirred to make the modifier evenly dispersed in the base asphalt. Finally, the mixed base asphalt is cooled to a certain temperature to complete the processing of the modified asphalt.

[0003] Regarding the processing of modified asphalt, the utility model patent with publication number CN212396541U discloses a modified asphalt mixing tank, which stirs the modifier and base asphalt through stirring shafts evenly distributed in the tank body. At the same time, the stirring rods connected to the sides of the stirring shaft cooperate with each other, which can effectively reduce the resistance of the stirring shaft when the modified asphalt is stirred, and effectively improve the stirring efficiency of the modified asphalt.

[0004] The above technical solution has problems when processing modified asphalt: 1. Since the heated base asphalt has a certain viscosity, when the base asphalt is stirred, if the stirring time is too short, the base asphalt at the bottom cannot be evenly mixed with the modifier, resulting in a decrease in the quality of the modified asphalt after processing. If the base asphalt and the modifier are stirred for a long time, the processing efficiency of the modified asphalt will be reduced; 2. When the modifier is added to the base asphalt, the modifier may accumulate together and easily agglomerate into lumps, which in turn causes the modifier to still not be evenly dispersed during the stirring process, further resulting in a decrease in the quality of the modified asphalt after processing.

[0038] It should be noted that the left end of the loading port 22 is connected to an external grinding unit.

[0039] The conveying unit 2 intermittently discharges the modifier to the surface of the base asphalt in a circular manner; specifically, the heated base asphalt is first fed from the feed barrel 12 into the mixing barrel 1, and then the grinding unit is started to feed the ground modifier from the feed port 22 into the conveying barrel 21, and then the material shifting mechanism 24 is started to continuously shift the modifier into each storage groove 23, so that the modifier can pass through the inclined surface of the storage groove 23 and the corresponding inclined surface of the square hole 11 and fall into the surface of the base asphalt in the mixing barrel 1, and the square holes 11 are evenly arranged circumferentially, thereby achieving uniform feeding of the modifier to the surface of the base asphalt through circular feeding, preventing the modifier from piling up, and ensuring uniform mixing of the modifier and the base asphalt. After the mixing of the modifier and the base asphalt is completed, the modified asphalt in the mixing barrel 1 can flow out of the mixing barrel 1 by opening the sealing door 13, and the modified asphalt is collected and cooled to complete the processing of the modified asphalt.

The material-discharging mechanism 24 includes a plurality of evenly arranged material-discharging plates 241 that are slidably installed in the conveying cylinder 21.

[0044] The stirring unit 3 is used for continuously stirring the base asphalt and the modifier; specifically, the starting motor 31 drives the rotating rod 33 to rotate counterclockwise through the transmission shaft 32, and the rotating rod 33 can drive its corresponding stirring rod 35 to rotate. At the same time, the transmission shaft 32 drives the connecting sleeve 34 to rotate synchronously through the shaking mechanism 36, so that the connecting sleeve 34 drives its corresponding stirring rod 35 to rotate, thereby realizing continuous stirring of the base asphalt and the modifier, and the shaking mechanism 36 can drive the rotating rod 33 and the connecting sleeve 34 to shake up and down, so that the stirring rod 35 can shake up and down while rotating the base asphalt and the modifier, thereby increasing the stirring effect of the base asphalt and the modifier.

[0046] The shaking mechanism 36 is used to drive the stirring rod 35 to shake up and down; specifically, when the transmission shaft 32 rotates, the transmission shaft 32 drives the shaking plate 361 to rotate, and the shaking plate 361 drives the synchronous plate 364 to rotate through the connecting rod 363, so that the synchronous plate 364 drives the connecting sleeve 34 to rotate through the round rod 365 and the fixed rod 366, and then the connecting sleeve 34 drives the corresponding multiple stirring rods 35 to rotate, and at the same time, the shaking plate 361 can drive the matching column 367 to rotate.

When the matching column 367 and the fixed block 15 are separated, the shaking plate 361 can The shaking plate 361 is used to return to its initial position downward, and under the action of the inclined surface of the lower pressure block 17, the matching column 367 can drive the shaking plate 361 to return to its initial position downward, thereby preventing the stirring rod 35 from being unable to return to its initial position downward under the action of the base asphalt, and the fixed block 15 and the lower pressure block 17 are both provided with multiple ones, thereby realizing the up and down shaking of the shaking plate 361, so that the shaking plate 361 drives the synchronous plate 364 to shake up and down through the connecting rod 363, and then the synchronous plate 364 drives the stirring rod 35 corresponding to the rotating rod 33 to shake up and down through the rotating rod 33, and at the same time, the synchronous plate 364 drives the stirring rod 35 corresponding to the connecting sleeve 34 to shake up and down through the round rod 365 and the fixed rod 366, thereby increasing the stirring effect of the stirring rod 35 on the base asphalt.

[0047] See also Figure 2 and Figure 7 The lifting unit 4 includes a rotating disk 41 which is slidably sleeved on the outside of the transmission shaft 32, and the rotating disk 41 is slidably connected to the mixing barrel 1 through a driving member 42.

The circular plate is driven to move up and down by starting the multi-stage push rod, so that the circular plate drives the rotating disk 41 to move up and down through the sliding rod.

[0050] The lifting unit 4 is used to lift the base asphalt at the bottom to the upper surface, thereby ensuring that the modifier can be evenly mixed into the base asphalt, while increasing the mixing efficiency of the modifier and the base asphalt; specifically, when the transmission shaft 32 rotates, the transmission shaft 32 drives the lifting plate 44 to rotate synchronously through the rotating disk 41, and at the same time, the driving member 42 is started to drive the rotating disk 41 to move upward, so that the rotating disk 41 can drive the lifting plate 44 to move upward, and then the horizontal section of the lifting plate 44 can lift the base asphalt at the bottom to the upper surface, and at the same time, the containment mechanism 45 can form an open cavity with the horizontal section of the lifting plate 44, thereby ensuring that the base asphalt at the bottom can be completely lifted to the upper surface.

[0054] When the horizontal section of the lifting plate 44 moves to the upper surface of the base asphalt, the lifting plate 44 moves upward to the initial position relative to the rotating disk 41 under the action of the extension spring 43, and the sliding plate 456 returns to the initial position relative to the square groove 431, so that the sliding plate 456 drives the two guard plates 451 to rotate away from each other through the transmission rod 452, and at the same time, the sliding plate 456 drives the square plate 453 to rotate away from the vertical section of the lifting plate 44 through the square rod 455 and the L-shaped rod 454, so that the lifting plate 44 lifts the base asphalt at the bottom to the upper surface, and when the rotating disk 41 moves downward, the rotating disk 41 can drive the lifting plate 44 to return to the initial position downward, so that the lifting plate 44 continues to lift the base asphalt at the bottom upward.

Matching rods 368 are fixedly installed at the positions of the outer side of the synchronous plate 364 corresponding to the corrugated grooves 412, and the matching rods 368 are all slidably installed in their corresponding corrugated grooves 412. A plurality of staggered shear rods 351 are fixedly installed on the opposite sides of two adjacent stirring rods 35.

[0056] When the synchronous plate 364 moves up and down, the synchronous plate 364 rotates back and forth under the action of the matching rod 368 and the corrugated groove 412, so that the synchronous plate 364 drives the connecting sleeve 34 to rotate back and forth through the round rod 365 and the fixed rod 366, and the synchronous plate 364 and the rotating rod 33 are rotationally connected, so that the stirring rod 35 corresponding to the connecting sleeve 34 rotates back and forth relative to the stirring rod 35 corresponding to the rotating rod 33, and the stirring rod 35 corresponding to the connecting sleeve 34 and the stirring rod 35 corresponding to the rotating rod 33 are staggered up and down, so that the shear rods 351 on the opposite sides of two adjacent stirring rods 35 can shear the modifier in the base asphalt to prevent the modifier from agglomerating and causing the modifier to be unable to be evenly mixed with the base asphalt.

[0057] See also Figure 2 and Figure 3 The positions of the mixing barrel 1 corresponding to the square holes 11 are all equipped with baffle plates 19 for sliding up and down through the downward pressure spring 18, and the lower end of the baffle plate 19 is arranged in close contact with the lower inner wall of the corresponding square hole 11, and the upper ends of the plurality of baffle plates 19 are commonly equipped with lifting rings 10 on the opposite sides, and the lifting rings 10 are used to cooperate with the lifting plate 44 to drive the baffle plate 19 to move upward.

[0058] When the modifier moves through the storage trough 23 to its corresponding square hole 11, the baffle plate 19 can block the modifier, and when the lifting plate 44 moves upward to the upper limit position, the lifting plate 44 can drive the lifting ring 10 to move upward, and then the lifting ring 10 drives all the baffle plates 19 to move upward, so that the modifier in all the square holes 11 can be evenly discharged to the surface of the base asphalt, and when the lifting plate 44 moves downward, the baffle plate 19 returns to its initial position under the action of the downward pressure spring 18, thereby realizing intermittent annular discharge of the modifier, further ensuring that the modifier and the base asphalt are evenly mixed.

[0059] In addition, the present invention also provides a modified asphalt processing method, which is completed by using a modified asphalt processing device, and the specific steps are as follows: S1, base asphalt loading: the base asphalt heated to a certain temperature is placed from the feeding cylinder 12 into the mixing cylinder 1.

[0060] S2. Loading of modifier: Start the annular electric slider assembly 242 to drive multiple material stripping plates 241 to move synchronously in the conveying cylinder 21, so that the material stripping plate 241 pushes the modifier in the conveying cylinder 21 into each storage groove 23, and moves the modifier to the square hole 11 corresponding to the storage groove 23, and the baffle plate 19 can block the modifier. When the lifting plate 44 moves upward to the upper limit position, the lifting plate 44 drives all the baffle plates 19 to move upward through the lifting ring 10, so that the modifiers in all the square holes 11 can be evenly discharged to the base asphalt surface at the same time, thereby realizing intermittent annular discharge of the modifier.

[0061] S3, raw material mixing and lifting: start the motor 31 and finally drive the stirring rod 35 to continuously stir the base asphalt and the modifier through the transmission shaft 32. When the transmission shaft 32 drives the shaking plate 361 to rotate, the shaking plate 361 can drive the matching column 367 to rotate, and the matching column 367 drives the shaking plate 361 to move up and down under the action of the fixed block 15 and the lower pressing block 17, so that the shaking plate 361 drives the synchronous plate 364 to shake up and down through the connecting rod 363, and then the synchronous plate 364 drives the stirring rod 35 corresponding to the rotating rod 33 to shake up and down through the rotating rod 33. At the same time, the synchronous plate 364 drives the stirring rod 35 corresponding to the connecting sleeve 34 to shake up and down through the round rod 365 and the fixed rod 366, thereby increasing the stirring effect of the stirring rod 35 on the base asphalt. When the synchronous plate 364 moves up and down, the synchronous plate 364 reciprocates under the action of the matching rod 368 and the corrugated groove 412, so that the synchronous plate 364 drives the connecting sleeve 34 to reciprocate through the round rod 365 and the fixed rod 366, so that the shear rods 351 on the opposite sides of two adjacent stirring rods 35 can shear the modifier in the base asphalt to prevent the modifier from agglomerating and causing the modifier to be unable to be evenly mixed with the base asphalt.

[0062] At the same time, the driving member 42 is started to drive the rotating disk 41 to move upward, so that the rotating disk 41 drives the sliding plate 456 to move upward through the pulling rod 457, and the horizontal section of the lifting plate 44 cannot move upward under the pressure of the base asphalt and compresses the extension spring 43, so that the sliding plate 456 drives the two guard plates 451 to rotate in the direction of approaching each other through the transmission rod 452, and at the same time, the sliding plate 456 drives the square plate 453 to rotate in the direction close to the vertical section of the lifting plate 44 through the square rod 455 and the L-shaped rod 454, so that the two guard plates 451 and the square plate 453 and the horizontal section of the lifting plate 44 form an open cavity, and at the same time, the sliding plate 456 moves to the upper inner wall of the square groove 431, so that the rotating disk 41 drives the lifting plate 44 to move upward through the pulling rod 457 and the sliding plate 456, thereby lifting the bottom base asphalt upward.

[0063] S4, cooling the modified asphalt: opening the sealed door 13, taking out the modified asphalt after production from the mixing drum 1 and cooling it, thus completing the processing of the modified asphalt.

[0064] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
