Description

Technical Field

[0001] This utility model relates to the field of asphalt emulsification reaction technology, and in particular to a reaction vessel for emulsifying asphalt mixtures. Background Technology

[0002] In today's era of booming infrastructure construction, road engineering, as a key component, places extremely high demands on the performance of asphalt mixture emulsification reactors. With the increasing traffic volume and the continuous improvement of road quality standards, emulsified asphalt is being used more and more widely in road paving, maintenance and other fields. In the mixing stage, most traditional asphalt mixture emulsification reactors use a simple single-shaft stirring method, which has a single stirring action and cannot achieve all-round turning of materials. This results in a situation where, during the emulsification process, the material near the mixing shaft moves violently and mixes quickly, while areas far from the mixing shaft are prone to forming mixing dead zones. The asphalt mixture and emulsifier cannot fully contact and mix evenly. Furthermore, single-shaft mixing is inefficient, often requiring extended mixing time to achieve the desired uniformity. This undoubtedly increases production costs and reduces efficiency, making it unsuitable for the large-scale, high-efficiency pace of modern road construction. On the other hand, traditional reactors present significant maintenance challenges. Their covers are typically secured with numerous bolts or feature complex welded structures. Cleaning the internal mixing components and reactor walls requires operators to spend considerable time unscrewing each bolt and using specialized tools, making the process cumbersome and prone to errors, significantly increasing labor costs and reducing cleaning and maintenance efficiency. Therefore, we propose a reactor for asphalt mixture emulsification to address this problem. Utility Model Content

[0003] The purpose of this invention is to provide a reaction vessel for emulsifying asphalt mixtures to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A reaction vessel for emulsifying asphalt mixtures includes: a reaction vessel, a cover provided on the top of the reaction vessel body, and a stirring assembly provided inside the reaction vessel body. The stirring assembly includes: a first gear, a gear ring, and two sets of second gears. The gear ring is fixedly installed on the inner wall of the cover. Both sets of second gears mesh with the first gear and the gear ring. A stirring shaft first and a stirring shaft second are fixedly installed at the bottom of the first gear and the two sets of second gears, respectively. Multiple sets of connecting rings first and connecting rings are fixedly installed on the outer sides of the first stirring shaft and the two sets of second stirring shafts, respectively. Multiple sets of stirring rods are fixedly installed on the outer sides of connecting ring one and connecting ring two, respectively. Shells are fixedly installed on both sides of the reactor. Placement grooves, sliding grooves, and rectangular grooves are provided inside the two sets of shells. Disassembly components are provided inside the placement grooves, sliding grooves, and rectangular grooves on the same side. The disassembly components include: a first inclined block, with a second inclined block movably abutting against its inclined surface; a rod is fixedly installed on one side of the first inclined block, movably inserted into the inside of the cover; a pull rod is fixedly installed at the bottom of the second inclined block, and a circular plate is fixedly installed on the outer side of the pull rod.

[0006] Preferably, a motor is fixedly installed on the top of the cover, a connecting rod is fixedly installed on the output end of the motor, a fixed shaft and a rotating shaft are fixedly installed on the top of the first gear and the two sets of second gears, respectively, the fixed shaft is fixedly connected to the connecting rod, and both sets of rotating shafts are rotatably connected to the connecting rod.

[0007] Preferably, the first and second inclined blocks located on the same side are slidably installed inside the corresponding placement slots, and springs are sleeved on the outer sides of both sets of insertion rods. The two ends of the springs are fixedly connected to the inner wall of the corresponding first inclined block and the placement slot.

[0008] Preferably, the two sets of circular plates are slidably installed inside the corresponding slide grooves, and springs are sleeved on the outer sides of the two sets of pull rods. The two ends of the springs are fixedly connected to the inner wall of one side of the corresponding circular plate and slide groove, respectively.

[0009] Preferably, both sets of pull rods slide through into the interior of corresponding rectangular slots, and both sets of pull rods have sliders fixedly installed at their bottom ends. The two sets of sliders are slidably installed inside the corresponding rectangular slots, and both sets of sliders have connecting blocks fixedly installed on one side. Both sets of connecting blocks have pull plates fixedly installed on one side.

[0010] Preferably, a feed hopper is fixedly installed on one side of the reactor, a sealing cover is provided on the top of the feed hopper, and a discharge pipe and three sets of support legs are fixedly installed at the bottom of the reactor.

[0011] In this invention, an asphalt mixture emulsification reactor is provided with a stirring assembly, a cover, and a motor. The motor drives a connecting rod, a first gear, and two sets of second gears to rotate. Both sets of second gears mesh with the first gear, and also with a gear ring. This causes the first gear to rotate the bottom stirring rod and its outer connecting ring and stirring rod. Simultaneously, the two sets of second gears rotate the bottom stirring shaft while moving outside the gear ring. This allows the two sets of second gears to rotate the outer connecting ring and its outer stirring rod, resulting in coordinated and counter-rotating stirring of the stirring rods. This complex and sophisticated motion pattern ensures that the material is thoroughly agitated within the reactor, eliminating any mixing blind spots and ensuring that each particle of asphalt mixture is uniformly mixed with the emulsifier. This effectively avoids problems such as poor emulsification and product stability caused by uneven mixing, resulting in higher quality emulsified asphalt. Furthermore, the multiple sets of stirring shafts and rods accelerate the mixing efficiency.

[0012] In this invention, an asphalt mixture emulsification reactor is provided with a shell, a cover, and a disassembly assembly. By pulling the pull plates on both sides of the shell, the two sets of pull plates drive the corresponding connecting blocks and sliders to move. The sliders drive the pull rod, the circular plate, and the second inclined block to move, while simultaneously squeezing the second spring. At this time, the spring returns to its original position, ensuring that the inclined surfaces of the first and second inclined blocks are always in contact with the inclined surface of the second inclined block. This allows the insert rod on one side of the first inclined block to detach from the inside of the cover, facilitating the disassembly of the cover. This structure is simple and easy to operate, allowing for quick installation and disassembly of the cover. Workers can quickly access the stirring assembly and the inner wall of the reactor, enabling timely cleaning of asphalt mixture adhering to the stirring rod and the reactor wall, preventing the material from drying and hardening, providing a clean equipment environment for the next batch of production, ensuring stable product quality, and timely cleaning and maintenance can effectively prevent material residue from corroding and wearing equipment components, reducing maintenance costs and extending the service life of the stirring assembly and the reactor.

The placement grooves, sliding grooves and rectangular grooves on the same side are provided with disassembly components 5. Disassembly components 5 include: inclined block 1 502, inclined block 1 502 movably abutting against inclined block 2 503, a plug rod 501 is fixedly installed on one side of inclined block 1 502, the plug rod 501 is movably inserted into the inside of the cover 2, a pull rod 504 is fixedly installed at the bottom of inclined block 2 503, and a circular plate 505 is fixedly installed on the outer side of the pull rod.

[0020] In this embodiment, a motor 6 is fixedly installed on the top of the cover 2, and a connecting rod 704 is fixedly installed on the output end of the motor 6. A fixed shaft and a rotating shaft are fixedly installed on the top of the first gear 702 and the two sets of second gears 703, respectively. The fixed shaft is fixedly connected to the connecting rod 704, and the two sets of rotating shafts are rotatably connected to the connecting rod 704. This facilitates the rotation of the first gear 702 driving the bottom stirring shaft 706, the connecting ring 707, and the stirring rod 710. It also facilitates the movement and rotation of the bottom stirring shaft 705, the connecting ring 708, and the stirring rod 709 driven by the two sets of second gears 703. The first inclined block 502 and the second inclined block 503 located on the same side are slidably installed inside the corresponding placement slots. Springs 509 are sleeved on the outer side of the two sets of insertion rods 501. The two ends of the two sets of springs 509 are fixedly connected to the corresponding inclined block 502 and the inner wall of one side of the placement slot, respectively. This facilitates the reset of the inclined block 502 and the installation and disassembly of the cover 2.

[0021] In this embodiment, two sets of circular plates 505 are slidably installed inside corresponding grooves. Springs 510 are sleeved on the outer sides of both sets of pull rods 504. The two ends of the springs 510 are fixedly connected to the corresponding circular plate 505 and one inner wall of the groove, respectively, facilitating the reset of the inclined block 503 and the quick disassembly and installation of the cover 2. Both sets of pull rods 504 slide through the interior of corresponding rectangular grooves. A slider 506 is fixedly installed at the bottom of each set of pull rods 504. The two sliders 506 are... The sliding blocks are installed inside the corresponding rectangular slots. Connecting blocks 507 are fixedly installed on one side of each of the two sets of sliding blocks 506. Pull plates 508 are fixedly installed on one side of each of the two sets of connecting blocks 507, which facilitates the rapid movement of the pull rod 504 and makes it easier to disassemble and install the cover 2. A feed hopper 4 is fixedly installed on one side of the reactor 1. A sealing cover 8 is provided on the top of the feed hopper 4. A discharge pipe 9 and three sets of support legs are fixedly installed at the bottom of the reactor 1, which facilitates the feeding of materials and the mixed asphalt mixture into the reactor 1.

[0022] In this embodiment, during use, the asphalt mixture and emulsifier are fed into the reactor 1 through the feed hopper 4, and then the sealing cover 8 is closed. The drive motor 6 rotates the connecting rod 704, gear 1 702, and two sets of gears 2 703. Both sets of gears 2 703 mesh with gear 1 702, and also mesh with the gear ring 701. As the gears 2 703 rotate, they travel on the gear ring 701. This causes gear 1 702 to rotate the bottom stirring rod 1 710 and its outer connecting ring 1 707 and stirring rod 1 710. The two sets of gears 2 703 simultaneously rotate the bottom stirring shaft 2 705 and travel outside the gear ring 701. This causes the two sets of stirring shaft 2 705 to rotate and move the outer connecting ring 2 708 and its outer stirring rod 2 709, moving in the opposite direction to the stirring direction of stirring rod 1 710. This facilitates better, more thorough, and more uniform mixing of the asphalt mixture inside the reactor 1. Finally, the asphalt mixture, after being fully mixed, is discharged from the discharge pipe 9. By pulling the pull plates 508 on both sides of the housing 3, the two sets of pull plates 508 drive the corresponding connecting blocks 507 and sliders 506 to move. This causes the sliders 506 to drive the pull rods 504, the circular plate 505, and the second inclined block 503 to move, while simultaneously squeezing the second spring 510. At this time, through the reset of the first spring 509, the inclined surfaces of the first inclined block 502 and the second inclined block 503 are always in contact, so that one side of the first inclined block 502... The insertion rod 501 is disengaged from the inside of the cover 2, which facilitates the disassembly of the cover 2 and the cleaning of the inner wall of the stirring assembly 7 and the reactor 1. During installation, the reset of the second spring 510 causes the inclined surface of the second inclined block 503 to press against the inclined surface of the first inclined block 502, which causes the first inclined block 502 to drive the insertion rod 501 to re-insert into the inside of the cover 2 while pressing the first spring 509. This makes it easier to fix the cover 2 and facilitates the normal operation of the cleaned and maintained stirring assembly 7 and reactor 1.
