Description

Technical Field

[0001] The invention relates to the field of road construction and maintenance, and in particular to a standardized construction process for recycling the entire structure of waste municipal roads. Background Art

[0002] At present, with the acceleration of urbanization, a large number of old municipal roads are facing the need for renovation and reconstruction. The traditional way of dealing with them is usually to treat the waste pavement materials as construction waste, which not only wastes a lot of precious resources, but also causes serious pollution to the environment.

[0003] There are some commonly used methods and technical means in the industry, for example, on-site cold recycling, which is to directly mix the waste asphalt mixture with other materials on site and then spread and compact it. Although this method reduces transportation costs, it is prone to uneven mixing problems in actual operation, resulting in unstable project quality. Therefore, technical personnel in this field provide a standardized construction process for the full-structure recycling of waste municipal roads to solve the problems raised in the above background technology. Summary of the invention

[0004] 1. Technical problems solved In view of the shortcomings of the prior art, the present invention provides a standardized construction process for the recycling of the entire structure of waste municipal roads, which solves the problem of uneven mixing after directly mixing waste asphalt mixture with other materials on site and then paving and compacting.

[0005] 2. Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: A standardized construction process for recycling the entire structure of a waste municipal road comprises a first conveying device, a first crushing device, a second conveying device, a second crushing device and a screening device, wherein the first crushing device comprises a first base, a hammer crusher, a driving motor, a threaded nail, an adjustment groove, a nut, a first guide plate and a second guide plate, wherein four adjustment grooves arranged on the mounting base of the driving motor correspond to four threaded nails passing through them respectively, and nuts are arranged on the outer walls of the four threaded nails; A third material guide plate is fixedly arranged at one end of the second conveying device, and the second crushing device includes a second base and a jaw crusher; The screening device comprises a support frame, a sealing plate and bolts, two vertical plates are fixedly arranged on the upper end of the support frame, a servo motor is fixedly arranged on one side of one of the vertical plates through a fixing block, a screw rod is fixedly connected to the output end of the servo motor through a coupling, and screening frames are fixedly arranged on two sliders connected to the screw rod through outer wall threads, and vibration motors are fixedly arranged on one side of the two screening frames, and one of the screening frames is arranged at the bottom end of the discharge port of the jaw crusher; Through the above technical scheme, the device sets a first conveying device, a first crushing device, a second conveying device, a second crushing device and a screening device and other structures, and processes the waste materials to make them reusable materials for reuse. The waste materials can be recycled and processed and reused, thereby realizing the reuse of resources and reducing the consumption of raw materials. At the same time, by setting two screening frames, when there are more unqualified raw materials in one of the screening frames during screening, the screening frame is controlled by a servo motor to move, so that the other one can perform screening, and then the unqualified materials in the removed screening frame are taken out. The unqualified materials can be taken out without affecting the process, without shutting down the device, avoiding the problem of repeated starting of the device, and improving work efficiency. By linking the processing devices, each device can cooperate with each other to work, reducing the intermediate process, and turning the work process into an automated operation, which can not only reduce the use of manpower, but also improve construction efficiency, shorten construction period, and reduce construction costs.

[0006] Furthermore, two first reinforcement frames are fixedly arranged between the first base and the hammer crusher; Through the above technical solution, by setting the first reinforcement frame, since the hammer crusher has a large movement during crushing, the setting of the first reinforcement frame can strengthen the connection between the first base and the hammer crusher, thereby avoiding problems with the hammer crusher during processing.

[0007] Further, the first guide plate is arranged at the lower end of the inlet of the hammer crusher, and one end of the first guide plate away from the hammer crusher is arranged at the bottom end of the conveyor belt of the first conveyor device; Through the above technical solution, the crushed material enters the hammer crusher through the first conveying device. Since the material has not been crushed yet and has a large volume, the material falls on the first guide plate and enters the hammer crusher. On the one hand, it can reduce the impact force generated by the material falling directly into the hammer crusher, and on the other hand, it can also play a guiding role.

[0008] Further, the second material guide plate is fixedly arranged on one side of the discharge port at the bottom end of the hammer crusher, and the second material guide plate is arranged on the upper end of the second conveying device; Through the above technical solution, the crushed material falls onto the upper end of the second conveying device through the drop opening, and the material discharged from the drop opening is blocked by the second material guide plate.

[0009] Furthermore, a plurality of baffles are fixedly provided on the upper end of the conveyor belt of the second conveying device; Through the above technical solution, the material after being crushed by the hammer crusher is smaller. The smaller material will be impacted when falling and may also flow downward. The baffle is set to block the material falling on the second conveying device to prevent the material from flowing downward.

[0010] Further, the third guide plate is arranged at the upper end of the feed inlet of the jaw crusher; Through the above technical solution, the third guide plate is arranged to guide the material conveyed by the second conveying device, so that the material can accurately fall into the jaw crusher through the third guide plate, so that the jaw crusher can finely crush the material.

[0011] Furthermore, two second reinforcement frames are fixedly arranged between the second base and the jaw crusher; Through the above technical solution, by setting the second reinforcement frame, since the jaw crusher has a large movement during crushing, the second reinforcement frame can strengthen the connection between the second base and the jaw crusher to avoid problems with the jaw crusher during processing.

[0012] Furthermore, a push plate is nested inside the two screening frames, and a sealing plate is fixed on one side of the two screening frames by two bolts; Through the above technical solution, the sealing plate is fixedly connected by bolts. When cleaning unqualified materials in the screening frame, the sealing plate is removed by loosening the bolts, and then the push plate is pushed to push the unqualified materials out of the opening. The pushed out materials can be placed on the upper end of the second conveying device and continue to be conveyed into the jaw crusher for crushing again.

[0013] Furthermore, one end of the screw rod away from the servo motor is rotatably arranged inside the fixing seat, and the fixing seat is fixedly connected to the vertical plate; Through the above technical solution, a section of the screw rod needs to be restricted to ensure that the transmission device can move.

[0014] The invention is applied to a standardized construction process for recycling the entire structure of waste municipal roads, including the following steps: S1: Clean up the construction site, remove debris, and level the site; S2: Start the excavator and start to dig the materials on the surface of the waste road; S3: The excavated materials are sent to the hammer crusher in the first crushing device through the first conveying device for the first step of preliminary crushing, and the materials after the preliminary crushing are sent to the jaw crusher in the second crushing device through the second conveying device for fine crushing; S4: The finely crushed material enters the screening frame through the discharge port of the jaw crusher and is screened by the vibrating motor; S5: Qualified fine particles are sent to the mixer for mixing, the bolts are loosened and the sealing plate is removed, the push plate is pushed to push out the unqualified materials and then placed on the upper end of the second conveyor for re-crushing; S6: Qualified fine particles, fresh asphalt and other additives are fed into the mixer; S7: Start the mixer and adjust the parameters to ensure uniform mixing; S8: Deliver the mixed recycled mixture to the construction site and spread it evenly using a paver; S9: Start the roller and perform compaction at the specified times and speed; S10: Test the density and strength of the compacted road to ensure that it meets the design requirements; S11: After completing the construction of one section of road, proceed to the next section.

Obviously, the specific embodiments described are only part of the specific embodiments of the present invention, not all of the specific embodiments. Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The crushed materials pass through the first conveyor device 1. The material 1 enters the interior of the hammer crusher 202. Since the material has not been crushed yet and has a large volume, the material falls on the first guide plate 207 and enters the interior of the hammer crusher 202. On the one hand, it can reduce the impact force generated by the material falling directly into the hammer crusher 202. On the other hand, it can also play a guiding role.

The third guide plate 302 is arranged to guide the materials conveyed by the second conveying device 3 so that the materials can accurately fall into the jaw crusher 402 through the third guide plate 302, so that the jaw crusher 402 can finely crush the materials. Two second reinforcing frames 403 are fixedly arranged between the second base 401 and the jaw crusher 402. By setting the second reinforcing frames 403, since the jaw crusher 402 has a larger movement during crushing, the connection between the second base 401 and the jaw crusher 402 can be strengthened through the arrangement of the second reinforcing frames 403, so as to avoid problems with the jaw crusher 402 during processing.
