Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixture recycling, in particular to a large-proportion recycling device for road waste asphalt mixture. Background Art

[0002] With the development of society and the continuous advancement of road construction, more and more asphalt pavements need to be repaired and renovated, resulting in a large amount of waste asphalt mixtures. These waste asphalt mixtures not only occupy a large amount of land resources, but also cause serious pollution to the environment. At present, the recycling of waste asphalt mixtures has become an important research topic.

The large-scale recycling device for waste road asphalt mixture is fixedly connected to the bottom of the two sides of the shell. After the waste asphalt is crushed and recycled, the vibration motor fixedly connected to the middle position of the bottom end of the connecting cross plate is started, and the connecting cross plate and the screening net are driven to vibrate by the vibration motor to screen the asphalt after the crushing process. The asphalt that meets the crushing standards is screened out and guided to the first discharge port for discharge for secondary recovery. In the process of vibration screening, the buffer spring is used for buffering, which reduces the impact of vibration on the shell, improves the stability of the equipment during operation, and solves the problem of inconvenience in screening the crushed asphalt and poor treatment effect.

[0004] However, since asphalt has a certain ductility, it may deform when passing through the crushing roller to adapt to the extrusion force, resulting in unqualified crushing. In addition, the inclination direction of the new connecting cross plate and the screening net is consistent with the horizontal direction of the crushing roller. If the waste falls from the right side of the crushing roller after being crushed, it may fall directly into the second discharge port, causing the qualified waste to be crushed for the second time, wasting resources.

The device reduces the ductility of the waste asphalt by spraying cooling water, making it easier to be crushed, speeding up the processing speed, and improving the recycling efficiency.

[0022] A screening motor 11 is installed on the right side of the recycling box 1, and a crankshaft 12 is fixedly connected to the driving end of the screening motor 11. Two connecting sleeves 13 are rotatably connected to the crankshaft 12, and a connecting handle 14 is fixedly connected to the connecting sleeve 13. A connecting piece 15 is rotatably connected to the other end of the connecting handle 14. A sieve plate 16 is rotatably connected inside the recycling box 1, and the sieve plate 16 is fixedly connected to the connecting piece 15. A sieve slot 17 is provided on the sieve plate 16, and a guide rod 18 is fixedly connected to the sieve plate 16. There is a guide groove 19. After the crushing roller crushes the waste, no matter where it falls from the crushing roller, it will fall on the higher side of the screen plate 16. At this time, the screening motor 11 is started to drive the crankshaft 12 to rotate. The connecting sleeve 13 and the connecting handle 14 are connected with the crankshaft 12 and the connecting piece 15 to make the higher side of the screen plate 16 fluctuate up and down.

[0027] The working principle of a large-scale recycling device for waste asphalt mixture used in roads provided by the utility model is as follows:

[0028] The staff shovels the waste onto the waste conveyor belt 4, and the waste conveyor belt 4 conveys the asphalt waste to the feed port 2. In the process, it passes through the refrigeration water tank 5. There is a refrigeration pipe 6 inside the refrigeration water tank 5 for heat exchange, so that the water temperature in the water tank is reduced. The asphalt waste is sprayed on the surface of the waste through the spray head 7 to reduce the temperature of the asphalt waste, destroying its ductility, so that it can be easier to break during subsequent asphalt crushing. Water is added to the cooling water tank 5 through the water injection pipe. At the same time, since there is moisture on the surface of the waste, the dust generated by the waste during crushing can be suppressed.

[0029] Compared with the related art, the large-scale recycling equipment for road waste asphalt mixture provided by the utility model has the following beneficial effects:

[0030] By spraying cooling water, the equipment reduces the ductility of asphalt waste, making it easier to crush, speeding up the processing speed and improving the recycling efficiency. At the same time, the cooling water can suppress the dust generated during the crushing process, reduce pollution to the environment, protect the health of operators, and ensure that qualified waste does not enter the secondary crushing stage, avoiding excessive crushing that affects the quality, improving the quality of recycled waste, reducing energy costs, and having economic benefits.
