Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt recycling technology, specifically to an asphalt recycling device. Background Technology
[0002] Asphalt is mainly used in industrial fields such as road paving, coatings, plastics, and rubber. Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It has high viscosity and usually exists in liquid or semi-solid petroleum form. When asphalt is damaged after long-term use, if the damaged asphalt mixture is directly discarded, not only will it need to be reprocessed and repaired, but it will also cause environmental pollution because asphalt contains a large number of other products that are harmful to human health and the environment.
[0003] Existing patent CN212663756U discloses an environmentally friendly asphalt recycling device, including a recycling chamber and a crushing chamber. A crushing chamber is fixedly installed on one side of the recycling chamber. A first motor is fixedly installed on the front of the outer wall of the recycling chamber, and a control switch is fixedly installed on one side of the first motor. A rotating shaft is movably connected inside the recycling chamber, and a roller is fixedly installed around the rotating shaft. A conveyor belt is movably connected around the roller. This invention uses the control switch to start the first motor, which drives the roller to rotate via the rotating shaft. The roller then carries the conveyor belt, and asphalt is placed onto the conveyor belt. To prevent the asphalt from falling, baffles are used to block it, ensuring the asphalt is smoothly conveyed into the crushing chamber. Simultaneously, the lime in the asphalt is filtered out by the screen structure of the conveyor belt and flows to the bottom. Then, a suction fan is activated to draw the lime into the collection chamber through a perforation for collection.
[0004] Based on the search of the aforementioned patents and in conjunction with existing asphalt recycling devices, it was found that although the aforementioned asphalt recycling devices can crush asphalt and treat dust during use, their asphalt crushing method is relatively simple, resulting in a relatively poor crushing effect. Moreover, during dust treatment, the dust is not easy to flow into the cleanroom, thus reducing its practicality. Utility Model Content

[0023] Please see Figure 1 , Figure 2 as well as Figure 3This utility model provides a technical solution: an asphalt recycling device, including a crushing box 1 and a water tank 11. A crushing box 12 is fixedly connected to the top of the crushing box 1. Crushing components are provided inside the crushing box 1 and the crushing box 1. Dust removal components are provided on the crushing box 1 and the water tank 11. The crushing components include a first rotating shaft 21 connected to both sides inside the crushing box 12, a crushing roller 22 fixedly connected to the outside of the first rotating shaft 21, a first gear 23 fixedly connected to the outside of the first rotating shaft 21, a motor 24 fixedly connected to one end of one of the first rotating shafts 21, a second rotating shaft 25 connected to the bottom inside the crushing box 1, and a motor 24 fixedly connected to the outside of the second rotating shaft 25.

Two first gears 23 mesh, the first rotating shaft 21 is rotatably connected to the crushing box 12, and the second rotating shaft 25 is rotatably connected to the crushing box 1. A motor 24 is fixedly connected to the front first rotating shaft 21. The motor 24 can drive the front first rotating shaft 21 and the first gears 23 to rotate, thereby causing the back first rotating shaft 21 to rotate in the opposite direction. This, in turn, causes the two crushing rollers 22 to rotate in the opposite direction, thus performing initial compression and crushing of the asphalt. The rotation of the second shaft 25 can drive the blades 26 to rotate, thereby performing secondary crushing of the initially crushed asphalt. The asphalt is fully crushed. The power components include a driven bevel gear 41 fixedly connected to the lower outer side of the second rotating shaft 25, a driving bevel gear 42 connected to the driven bevel gear 41, a connecting shaft 43 fixedly connected to the driving bevel gear 42, a driving wheel 44 fixedly connected to the outer side of one of the first rotating shafts 21, a driven wheel 45 fixedly connected to the outer side of the connecting shaft 43, and a belt 46 disposed between the driving wheel 44 and the driven wheel 45. The driving wheel 44 and the driven wheel 45 are connected by the belt 46. The driving bevel gear 42 meshes with the driven bevel gear 41. The driving wheel 44 is fixedly connected to the first rotating shaft 21 on the front side. The first rotating shaft 21 rotates. The drive wheel 44 can rotate, which in turn drives the driven wheel 45 and the connecting shaft 43 to rotate via the belt 46. This, in turn, drives the drive bevel gear 42 to rotate, which in turn drives the driven bevel gear 41 and the second shaft 25 to rotate, which in turn drives the blade 26 to rotate. The first shaft 21 can drive the second shaft 25 to rotate without additional power, which can reduce the cost of use and maintenance. A vertical plate 71 is fixedly connected to the bottom of the crushing box 1. The connecting shaft 43 is rotatably connected to the vertical plate 71. The vertical plate 71 can support the rotation of the connecting shaft 43, prevent the connecting shaft 43 from swinging when rotating, and improve the rotational stability of the connecting shaft 43.
[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4The dust removal components include a blower 31 fixedly connected to the top of the crushing box 1, an air inlet pipe 32 fixedly connected to the output end of the blower 31, an air outlet pipe 33 fixedly connected to one side of the crushing box 1, multiple air vents 34 evenly arranged at the bottom of the air outlet pipe 33, and a shielding component to prevent dust from overflowing from the crushing box 12. The air vents 34 are connected to the air outlet pipe 33, which passes through the water tank 11 and extends into it. The air inlet pipe 32 is connected to the crushing box 1. The blower 31 can remove dust from the crushing box 12. Dust is discharged into the water tank 11 through the vent pipe 33 and diverted through the vent pipe 34, allowing the dust to be quickly discharged into the water. This enables rapid dust suppression and prevents dust from overflowing and polluting the environment. Multiple vents 81 are evenly spaced along the axis of the vent pipe 34, facilitating the rapid discharge of dust into the water and improving dust treatment efficiency. The shielding components include fixed shafts 51 connected to both sides of the top of the crushing box 12, and fixed connections to the fixed shafts 51. The system includes a baffle 52, an arc-shaped rod 53 fixedly connected to the bottom of the baffle 52, and a spring 54 sleeved on the outside of the arc-shaped rod 53. A fixed shaft 51 is rotatably connected to the crushing box 12. The arc-shaped rod 53 passes through the crushing box 12 and is slidably connected to it. Both ends of the spring 54 are fixedly connected to the baffle 52 and the inner wall of the crushing box 12, respectively. Asphalt can contact the baffle 52, causing the baffle 52 to rotate along the fixed shaft 51, thereby compressing the spring 54 and causing it to deform. The arc-shaped rod 53 prevents the spring 54 from tilting. The 54 reset mechanism can reset the baffle 52, which can seal and shield the top of the crushing box 12 to prevent a large amount of dust from overflowing and polluting the working environment. A liquid filling pipe 61 is fixedly connected to one side of the top of the water tank 11, and an exhaust pipe 62 is fixedly connected to the other side of the top of the water tank 11. A drain pipe 63 is fixedly connected to one side of the water tank 11, and a valve 64 is installed on the drain pipe 63. The liquid filling pipe 61 can easily add water to the water tank 11, the drain pipe 63 can easily discharge sewage, and the exhaust pipe 62 can easily discharge purified air.
[0025] Working principle: During operation, the motor 24 is started, which drives the first rotating shaft 21 and the first gear 23 to rotate. This, in turn, drives the other first gear 23 to rotate in the opposite direction, which in turn drives the two first rotating shafts 21 to rotate in the opposite direction. This causes the two crushing rollers 22 to rotate in the opposite direction. Simultaneously, the first rotating shaft 21 also drives the drive wheel 44 to rotate. The drive wheel 44, through the belt 46, drives the driven wheel 45 to rotate. The driven wheel 45, in turn, drives the connecting shaft 43 to rotate. The connecting shaft 43, in turn, drives the drive bevel gear 42 to rotate. The drive bevel gear 42, in turn, drives the driven bevel gear 41 to rotate. The driven bevel gear 41, in turn, drives the second rotating shaft 25 to rotate. The second rotating shaft 25, in turn, drives the blades 26 to rotate. Then, asphalt is fed into the crushing box 12. The baffle 52 can be pushed to rotate, and the rotation of the baffle 52 can cause the spring 54 to deform. When the asphalt enters between the two crushing rollers 22, the spring 54 returns to its original position, which can cause the baffle 52 to return to its original position and block the dust. At this time, the two crushing rollers 22 can perform preliminary crushing of the asphalt. The crushed asphalt falls into the crushing box 1, and can be crushed again by rotating the blade 26. The blower 31 is started, and the blower 31 can blow the dust into the water tank 11 through the air outlet 33. Then, it can be diverted through the air pipe 34 so that the dust can be quickly discharged into the water for purification. The purified air can be discharged through the exhaust pipe 62. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
