[0016] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0017] like Figure 1-4 As shown, in the embodiment, a device based on recycling of urban construction waste is provided, including a processing table 1, a fixing mechanism 2 and a cleaning mechanism 3. The processing table 1 is provided with a fixing mechanism 2 and a cleaning mechanism 3. The fixing mechanism 2 includes a feeding module 21 for driving the color steel plate to move and a clamping module 22 for clamping and fixing the color steel plate. The cleaning mechanism 3 includes cleaning units symmetrically arranged on both sides of the top surface of the processing table 1. The cleaning unit includes a position adjustment module 31, a grinding motor 32, a grinding roller 33, a correction roller 34 and a scraping module 35. The position adjustment module 31 includes two vertical and parallel mobile frames 311. The mobile frame 311 is provided with a grinding motor 32. The output end of the grinding motor 32 is connected to the grinding roller 33. The correction rollers 34 are symmetrically arranged on both sides of the grinding roller 33, and the correction rollers 34 are rotatably connected to the mobile frame 311. A scraping module 35 is also provided on one of the mobile frames 311. In this embodiment, the processing table 1 is installed on the ground, and the top surface of the processing table 1 should be ensured to be in a horizontal state during installation. The fixing mechanism 2 is used to fix the waste color steel plates to be recycled, wherein the feeding module 21 can be used to place the waste color steel plates to be recycled and drive them to move forward to the cleaning mechanism 3 to achieve the purpose of automatic feeding; the clamping module 22 is used to clamp the two sides of the color steel plates to be recycled to prevent their position from shifting during the cleaning process. The cleaning mechanism 3 is used to remove dirt on the outer surface of the color steel plate and impurities such as glue and foam board adhering to the inner surface, so that the color steel plate meets the recycling requirements, wherein the position adjustment module 31 is used to adjust the position of the mobile frame 311, and can adjust the distance between two adjacent mobile frames 311 to meet the processing requirements of color steel plates of different thicknesses, and the two mobile frames 311 are respectively located on the outside and inside of the color steel plate; the grinding motor 32 is used to drive the grinding roller 33 to rotate, and the two grinding rollers 33 can respectively grind the inner wall of the color steel plate. The outer wall and the outer wall are ground to remove the concrete and rust and other impurities adhered thereto, thereby obtaining a clean color steel plate for easy recycling; the two correction rollers 34 are respectively in close contact with the outer wall and the inner wall of the color steel plate. On the one hand, they can flatten the protrusions on the surface of the color steel plate to facilitate grinding by the grinding roller 33, and on the other hand, they can also crush the solid impurities such as concrete particles adhered to the surface of the color steel plate to make them fall off, which helps to improve the grinding effect of the grinding roller 33; the scraping module 35 is provided to separate the foam board from the inner wall of the color steel plate.

[0018] Specifically, the position adjustment module 31 also includes a first motor 312, a first screw rod 313, a sliding seat 314, a second motor 315 and a second screw rod 316. The first motor 312 is fixed on the processing table 1. The output end of the first motor 312 is connected to the first screw rod 313. The sliding seat 314 is threadedly connected to the first screw rod 313, and the sliding seat 314 is slidingly connected to the processing table 1. The second motor 315 is arranged on the sliding seat 314. The output end of the second motor 315 is connected to the second screw rod 316. The second screw rod 316 is provided with two threaded sections with opposite spiral directions. Each threaded section is threadedly connected to one of the moving frames 311, and the moving frame 311 is slidingly connected to the sliding seat 314. In this embodiment, the first screw rod 313 is transversely arranged on the processing table 1, and the first motor 312 can drive the first screw rod 313 to rotate, so that the sliding seat 314 slides back and forth on the processing table 1 to adjust the positions of the two mobile frames 311, so that one edge of the color steel plate is aligned with the gap between the two mobile frames 311. The second screw rod 316 is transversely arranged above the sliding seat 314, and the central axis of the first screw rod 313 is parallel to the central axis of the second screw rod 316. The second motor 315 can drive the second screw rod 316 to rotate, and the rotation of the second screw rod 316 can drive the two mobile frames 311 to move closer to or away from each other, thereby adjusting the distance between two adjacent grinding rollers 33 and two adjacent correction rollers 34, so as to achieve grinding and leveling of color steel plates of different thicknesses. In addition, since the first screw rod 313 and the sliding seat 314, and the second screw rod 316 and the moving frame 311 are all threadedly connected, they have a self-locking function, which can prevent the sliding seat 314 and the moving frame 311 from shifting due to vibration during the processing, thereby ensuring the grinding effect.

[0019] Specifically, the scraping module 35 includes a U-shaped rod 351, a cutting wire 352, an adjusting plate 353, a guide rod 354 and a tension adjusting module. One end of the mobile frame 311 is connected to the U-shaped rod 351 by torsion rotation. The bottom end of the cutting wire 352 is connected to the bottom end of the U-shaped rod 351. The top end of the cutting wire 352 passes through the through hole on the U-shaped rod 351 and is connected to the adjusting plate 353. The guide rod 354 is vertically fixed on the top of the U-shaped rod 351, and the adjusting plate 353 is slidably connected to the guide rod 354. The adjusting plate 353 is also connected to the tension adjusting module. In this embodiment, the U-shaped rod 351 is located at one end of the mobile frame 311 close to the clamping module 22, and the opening of the U-shaped rod 351 is also facing one side of the clamping module 22. The upper and lower ends of the U-shaped rod 351 are connected to the mobile frame 311 by torsion rotation, so that the user needs to apply a certain force to drive the U-shaped rod 351 to rotate, and the cutting wire 352 is subject to less resistance when cutting the foam, which will not cause the U-shaped rod 351 to rotate. If there is a protrusion on the inner wall of the color steel plate, the cutting wire 352 will be adaptively deformed when passing through the protrusion and pull the adjustment plate 353 to slide downward to prevent the cutting wire 352 from breaking, and the cutting wire 352 is arranged to abut against the inner wall of the color steel plate, so that when the cutting wire 352 and the color steel plate move relative to each other, the foam board can be separated from the color steel plate to achieve separate recovery of the color steel plate. The set tension adjustment module can adjust the tension of the cutting wire 352. In addition, an arc plate is also provided on the movable frame 311 located on the inner side of the color steel plate, and one end of the arc plate is connected to the steel wire, so that when the feeding module 21 drives the color steel plate to move, the peeled foam board can be compressed for easy recycling; the connection part between one end of the arc plate and the cutting steel wire 352 is made of flexible steel sheet, so that it can undergo adaptive deformation when the U-shaped rod 351 is rotated.

[0020] Specifically, the tension adjustment module includes an adjusting bolt 355, an abutment block 356 and a first spring 357. The adjusting bolt 355 is rotatably connected to the U-shaped rod 351. The adjusting bolt 355 is threadedly connected with the abutment block 356, and the abutment block 356 is slidably connected to the guide rod 354. One end of the first spring 357 is connected to the abutment block 356, and the other end of the first spring 357 is connected to the adjustment plate 353. In this embodiment, the adjusting bolt 355 is arranged vertically, and the abutment block 356 can be driven to slide up and down by screwing the adjusting bolt 355. The first spring 357 is used to provide tension for the cutting wire 352. When the abutment block 356 and the adjustment plate 353 are close to each other, the first spring 357 will be compressed, thereby increasing the tension on the cutting wire 352. A screwing groove is also provided on the adjusting bolt 355 to facilitate the user to perform the screwing operation.

[0021] Specifically, the cleaning mechanism 3 further includes a glue removal module 36, which includes a liquid storage tank 361, a pump body 362, a liquid infusion hose 363, a nozzle 364 and a triangular block 365. The liquid storage tank 361 is arranged on the processing table 1, and the liquid storage tank 361 is filled with a glue remover. The liquid storage tank 361 is provided with a pump body 362, one end of the liquid infusion hose 363 is connected to the pump body 362, and the other end of the liquid infusion hose 363 is connected to the nozzle 364, and the nozzle 364 is fixed on the U-shaped rod 351, and the U-shaped rod 351 is also provided with a triangular block 365. In this embodiment, since the foam board is cut and separated by the cutting wire 352, glue and foam will still remain on the inner side wall of the color steel plate, and the provided glue removal module 36 is used to remove the residual glue to prevent it from adhering to the correction roller 34 or the grinding roller 33. Among them, the glue remover is preferably a non-toxic solvent such as alcohol or WD40 to prevent workers from inhaling it and causing harm to their bodies; the infusion hose 363 is preferably a metal hose, which can adaptively deform when the movable frame 311 moves; the pump body 362 can pump the glue remover in the liquid storage tank 361 to the nozzle 364 through the infusion hose 363 and spray it out, so that the glue remover flows down along the inner wall of the color steel plate, so that the glue loses its viscosity and is easy to peel off; the triangular block 365 is vertically arranged, and one of the right-angled faces of the triangular block 365 is in contact with the inner wall of the color steel plate, so that during the movement of the color steel plate, a triangular groove can be opened on the top of the foam board, and the outlet of the nozzle 364 is aligned with the triangular groove. Since the gap cut by the cutting wire 352 is very narrow, it is difficult for the nozzle 364 to accurately spray the degumming agent into the gap. By opening a triangular groove, the degumming agent can be sprayed into the triangular groove during processing, and then the degumming agent will gradually flow into the gap cut by the cutting wire 352 along the inclined surface of the groove, thereby reducing the difficulty of operation.

[0022] Specifically, a collection box 37 is provided at one end of the processing table 1, and a liquid collection bin 38 is also provided at the bottom of the collection box 37, and a filter screen 39 is provided on the liquid collection bin 38. In this embodiment, the collection box 37 is used to collect the degumming agent waste liquid and the cut foam debris to avoid polluting the environment. The filter screen 39 is used to separate the degumming agent waste liquid and the foam debris, and allows the degumming agent waste liquid to flow into the liquid collection bin 38 for separate storage, which is convenient for subsequent processing. An opening is also provided on one side of the collection box 37, and the liquid collection bin 38 can be taken out of the collection box 37 through the opening, reducing the difficulty of operation.

[0023] Specifically, the feeding module 21 includes a conveyor belt 211, an electromagnetic suction cup 212 and a baffle 213. A receiving groove 11 is provided on the top of the processing table 1, a conveyor belt 211 is provided in the receiving groove 11, a baffle 213 is vertically provided on the conveyor belt 211, and an electromagnetic suction cup 212 is provided inside the conveyor belt 211. In this embodiment, the receiving groove 11 is provided along the length direction of the processing table 1, the conveyor belt 211 is horizontally fixedly installed in the receiving groove 11, and it is ensured that the top surface of the conveyor belt 211 is slightly higher than the top surface of the processing table 1. The roller of the conveyor belt 211 is connected with a motor for driving it to rotate. The color steel plate to be recycled is placed on the conveyor belt 211, and the conveyor belt 211 drives the color steel plate to move forward to realize automatic feeding. The baffle 213 abuts against one end of the color steel plate, and can assist in pushing the color steel plate to move synchronously when the conveyor belt 211 rotates, so as to avoid the color steel plate from slipping during the feeding process. When the electromagnetic chuck 212 is powered on, it can generate electromagnetic force, thereby assisting the color steel plate to be adsorbed on the conveyor belt 211, preventing the color steel plate from vibrating up and down and affecting the processing quality. In addition, the rotation direction of the grinding roller 33 is opposite to the moving direction of the color steel plate.

[0024] Specifically, the clamping module 22 includes an electric push rod 221, a clamping plate 222 and a guide roller 223. The electric push rods 221 are symmetrically arranged on both sides of the conveyor belt 211. The output end of the electric push rod 221 is connected to the clamping plate 222. Two or more guide rollers 223 are arranged on the side where the two clamping plates 222 are close to each other. In this embodiment, the two electric push rods 221 are coaxially arranged, and the electric push rod 221 is a retractable structure, which can drive the two clamping plates 222 to move closer to or away from each other, so as to clamp color steel plates of different sizes, and the applicability is better. The clamping plate 222 is a flat plate structure, and the clamping plate 222 is arranged vertically. The guide roller 223 is able to rotate, so as to reduce the friction between the color steel plate and the clamping plate 222, so that the feeding process can proceed smoothly.

[0025] Working principle: When in use, first place the color steel plate to be recycled on the conveyor belt 211, and make one end of the color steel plate abut against the baffle 213, then start the electric push rod 221, the electric push rod 221 drives the two clamping plates 222 to approach each other and abut against the outer wall of the color steel plate, then start the electromagnetic suction cup 212, and the magnetic force generated by the electromagnetic suction cup 212 adsorbs and fixes the color steel plate on the conveyor belt 211. Then start the first motor 312, the first motor 312 drives the first screw rod 313 to rotate, the first screw rod 313 rotates to drive the sliding seat 314 to slide, so as to adjust the position of the mobile frame 311, and make the two sides of the color steel plate respectively aligned with the gap between the two mobile frames 311 of one of the cleaning units, then start the second motor 315, the second motor 315 drives the second screw rod 316 to rotate, the second screw rod 316 rotates to drive the two mobile frames 311 to approach each other, so that the gap between the two adjacent grinding rollers 33 and the two adjacent correction rollers 34 is adapted to the thickness of the color steel plate. Then start the conveyor belt 211, which drives the color steel plate to move to the side close to the movable frame 311. During the movement, the color steel plate will first contact the cutting wire 352, and the cutting wire 352 will separate the foam board inside the color steel plate from the color steel plate body. At the same time, the triangular block 365 will open a triangular groove on the top of the foam board. At this time, the pump body 362 pumps the degumming agent in the liquid storage tank 361 to the nozzle 364 for spraying, so that the degumming agent is sprayed into the triangular groove, and then flows into the gap cut by the cutting wire 352 and contacts the inner wall of the color steel plate, so that the glue loses its viscosity and is easy to remove, and the excess degumming agent will flow to the liquid collection bin 38 below for temporary storage, which is convenient for subsequent processing. Then the color steel plate will pass through the gap between two adjacent correction rollers 34, and the correction roller 34 will squeeze the protrusions and curved parts on the surface of the color steel plate to make it flat. At the same time, the grinding motor 32 will drive the grinding roller 33 to rotate to grind the inner and outer sides of the color steel plate to remove impurities such as surface rust for easy recycling. The grinding roller 33 will also generate heat during the grinding process, thereby heating the color steel plate to eliminate internal stress and prevent the color steel plate from rebounding.

[0026] In addition, all the components used in this embodiment are commercially available.
