Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering, and more specifically, to a device for recycling urban construction waste. Background Art

[0002] With the aging of some old buildings and urban infrastructure and the expiration of their service life, more and more civil engineering construction projects are scrapped and demolished, resulting in a large amount of construction demolition waste.

[0003] In the prior art, for example, a Chinese invention patent with the publication number of CN112845262B discloses a method for recycling and reusing building color steel plates. It cleans the impurities on the surface of the steel plate through a cleaning branch chain, so that the outer surface of the steel plate remains clean. And a scraper is used to perform a secondary scraping treatment on the residual foam inside the steel plate. After the secondary scraping treatment, the inner wall of the steel plate is heated by a heating plate to melt the glue fixing the foam to the inner wall of the steel plate. Then, a reprocessing roller is used to collect and process the melted glue and broken foam mixture, and the inner wall of the steel plate is further cleaned. However, the above technical solution still has the following defects: 1. Unpleasant and toxic odors will be generated during the heating and melting process of the foam and glue, and inhalation by the staff will cause harm to the body; 2. During the process of demolishing a building, it is inevitable that the surface of the waste color steel plate will be deformed such as bulges. Therefore, when the foam processing mechanism cuts the foam, the scraper is likely to collide with the bulging part, resulting in damage to the scraper. Summary of the Invention

[0022] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0023] As Figures 1-4 shown, in the embodiment, a device for recycling urban construction waste is provided, which includes a processing table 1, a fixing mechanism 2 and a cleaning mechanism 3. The fixing mechanism 2 and the cleaning mechanism 3 are arranged on the processing table 1. The fixing mechanism 2 includes a feeding module 21 for driving the movement of the color steel plate 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 calibration roller 34 and a scraping module 35. The position adjustment module 31 includes two vertically and parallel moving frames 311. The grinding motor 32 is arranged on the moving frame 311. The output end of the grinding motor 32 is connected to the grinding roller 33. The calibration rollers 34 are symmetrically arranged on both sides of the grinding roller 33, and the calibration roller 34 is rotatably connected to the moving frame 311. The scraping module 35 is also arranged on one of the moving frames 311. In this embodiment, the processing table 1 is installed on the ground, and it should be ensured that the top surface of the processing table 1 is in a horizontal state during installation. The fixing mechanism 2 is used to fix the waste color steel plate to be recycled. Among them, the feeding module 21 can be used to place the waste color steel plate to be recycled and drive it forward to the cleaning mechanism 3 to achieve the purpose of automatic feeding; the clamping module 22 is used to clamp both sides of the color steel plate to be recycled to prevent its position from shifting during the process of cleaning the color steel plate. The cleaning mechanism 3 is used to remove the dirt on the outer surface of the color steel plate and impurities such as glue and foam board adhered to the inner surface, so that the color steel plate meets the recycling requirements. Among them, the position adjustment module 31 is used to adjust the position of the moving frame 311 and can adjust the distance between two adjacent moving frames 311 to meet the processing requirements of color steel plates with different thicknesses. The two moving frames 311 are respectively located outside and inside the color steel plate; the grinding motor 32 is used to drive the grinding roller 33 to rotate. The two grinding rollers 33 can respectively perform grinding operations on the inner and outer walls of the color steel plate to remove impurities such as concrete and rust adhered to it, so as to obtain a clean color steel plate for convenient recycling; the two calibration rollers 34 are respectively in close contact with the outer and inner walls of the color steel plate. On the one hand, it can flatten the protrusions on the surface of the color steel plate to facilitate the grinding roller 33 to perform grinding. On the other hand, it 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 provided scraping module 35 is used to separate the foam board from the inner wall of the color steel plate.

[0024] Specifically, the position adjustment module 31 further includes a first motor 312, a first lead screw 313, a sliding seat 314, a second motor 315 and a second lead screw 316. The first motor 312 is fixedly arranged on the processing table 1. The output end of the first motor 312 is connected to the first lead screw 313. The sliding seat 314 is threadedly connected to the first lead screw 313 and is slidably 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 lead screw 316. Two thread segments with opposite spiral directions are arranged on the second lead screw 316. Each thread segment is threadedly connected to one of the moving frames 311 respectively, and the moving frames 311 are slidably connected to the sliding seat 314. In this embodiment, the first lead screw 313 is horizontally arranged on the processing table 1. The first motor 312 can drive the first lead screw 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 moving frames 311, so that one side of the color steel plate is aligned with the gap between the two moving frames 311. The second lead screw 316 is horizontally arranged above the sliding seat 314, and the central axis of the first lead screw 313 is parallel to the central axis of the second lead screw 316. The second motor 315 can drive the second lead screw 316 to rotate, and the rotation of the second lead screw 316 can drive the two moving frames 311 to approach or move away from each other, so as to adjust the distance between two adjacent grinding rollers 33 and two adjacent straightening rollers 34, so as to realize the grinding and flattening of color steel plates with different thicknesses. In addition, since the connection between the first lead screw 313 and the sliding seat 314, and the connection between the second lead screw 316 and the moving frame 311 both adopt threaded connection, which has a self-locking function, it can prevent the sliding seat 314 and the moving frame 311 from shifting due to vibration during the processing, and ensure the grinding effect.

[0025] Specifically, the scraping module 35 includes a U-shaped rod 351, a cutting wire 352, an adjusting pressing plate 353, a guiding rod 354 and a tension adjusting module. One end of the moving frame 311 is torsionally rotatably connected to the U-shaped rod 351. 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 in the U-shaped rod 351 and is connected to the adjusting pressing plate 353. The guiding rod 354 is vertically fixed on the top of the U-shaped rod 351, and the adjusting pressing plate 353 is slidably connected to the guiding rod 354. A tension adjusting module is also connected to the adjusting pressing plate 353. In this embodiment, the U-shaped rod 351 is located at one end of the moving frame 311 close to the clamping module 22, and the opening of the U-shaped rod 351 also faces the side of the clamping module 22. The upper and lower ends of the U-shaped rod 351 are torsionally rotatably connected to the moving frame 311, 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 less resistant when cutting the foam, and it will not cause the U-shaped rod 351 to rotate. If there are protrusions on the inner side wall of the color steel plate, the cutting wire 352 will adaptively deform when passing through the protrusions and pull the adjusting pressing plate 353 to slide downward to prevent the cutting wire 352 from breaking, and the cutting wire 352 is in contact with the inner side wall of the color steel plate. Furthermore, 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 the separate recycling of the color steel plate. The provided tension adjusting module can adjust the tension of the cutting wire 352. In addition, an arc-shaped plate is also provided on the moving frame 311 located inside the color steel plate, and one end of the arc-shaped plate is connected to the wire. Furthermore, during the process of the feeding module 21 driving the color steel plate to move, the foam board that has been peeled off can be compressed, which is convenient for recycling; the connecting part between one end of the arc-shaped plate and the cutting wire 352 is made of a flexible steel sheet, so that it can adaptively deform when the U-shaped rod 351 rotates.

[0026] Specifically, the tension adjusting module includes an adjusting bolt 355, a abutting block 356 and a first spring 357. The adjusting bolt 355 is rotatably connected to the U-shaped rod 351. Abutting block 356 is threadedly connected to the adjusting bolt 355, and the abutting block 356 is slidably connected to the guiding rod 354. One end of the first spring 357 is connected to the abutting block 356, and the other end of the first spring 357 is connected to the adjusting pressing plate 353. In this embodiment, the adjusting bolt 355 is vertically arranged, and by screwing the adjusting bolt 355, the abutting block 356 can be driven to slide up and down. The first spring 357 is used to provide tension for the cutting wire 352. When the abutting block 356 and the adjusting pressing plate 353 approach each other, the first spring 357 will be compressed, and thus the tension of the cutting wire 352 will become larger. A screwing groove is also provided on the adjusting bolt 355 to facilitate the user's screwing operation.

[0027] Specifically, the cleaning mechanism 3 further includes a glue removal module 36. The glue removal module 36 includes a liquid storage tank 361, a pump body 362, an infusion hose 363, a spray head 364, and a triangular block 365. The liquid storage tank 361 is arranged on the processing table 1. The liquid storage tank 361 contains a glue remover. A pump body 362 is arranged on the liquid storage tank 361. One end of the infusion hose 363 is connected to the pump body 362, and the other end of the infusion hose 363 is connected to the spray head 364. The spray head 364 is fixedly arranged on the U-shaped rod 351, and a triangular block 365 is also arranged on the U-shaped rod 351. In this embodiment, after 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. The arranged glue removal module 36 is used to remove the remaining 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 harm to the body caused by inhalation by the staff; the infusion hose 363 is preferably a metal hose, which can undergo adaptive deformation when the moving frame 311 moves; the pump body 362 can pump the glue remover in the liquid storage tank 361 to the spray head 364 through the infusion hose 363 and then spray it out, so that the glue remover flows down along the inner side wall of the color steel plate, making the glue lose its viscosity and facilitating its peeling off; the triangular block 365 is arranged vertically, and one of the right-angled surfaces of the triangular block 365 abuts against the inner side wall of the color steel plate. Thus, during the movement of the color steel plate, a triangular groove can be opened at the top of the foam board, and the outlet of the spray head 364 is aligned with the triangular groove. Since the gap cut by the cutting wire 352 is very narrow, it is difficult for the spray head 364 to accurately spray the glue remover into the gap. By opening the triangular groove, the glue remover can be sprayed into the triangular groove during processing, and then the glue remover will gradually flow into the gap cut by the cutting wire 352 along the inclined surface of the groove, reducing the operation difficulty.

[0028] Specifically, a collection box 37 is arranged at one end of the processing table 1, and a liquid collection bin 38 is further arranged at the inner bottom of the collection box 37, and a filter screen 39 is arranged on the liquid collection bin 38. In this embodiment, the arranged collection box 37 is used to collect the waste liquid of the glue remover and the cut foam scraps to avoid environmental pollution. The arranged filter screen 39 is used to separate the waste liquid of the glue remover and the foam scraps, and make the waste liquid of the glue remover flow into the liquid collection bin 38 for separate storage, which is convenient for subsequent treatment. An opening is also arranged 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 operation difficulty.

[0029] Specifically, the feeding module 21 includes a conveyor belt 211, an electromagnetic chuck 212, and a baffle 213. A receiving groove 11 is provided at the top of the processing table 1. The conveyor belt 211 is arranged in the receiving groove 11. A baffle 213 is vertically arranged on the conveyor belt 211, and an electromagnetic chuck 212 is arranged inside the conveyor belt 211. In this embodiment, the receiving groove 11 is arranged along the length direction of the processing table 1. The conveyor belt 211 is horizontally and 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. A motor is connected to the roller of the conveyor belt 211 to drive its rotation. 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 achieve 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, avoiding the situation of the color steel plate slipping during the feeding process. When the electromagnetic chuck 212 is energized, it can generate electromagnetic force to assist in adsorbing the color steel plate on the conveyor belt 211 and prevent its up and down vibration from 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.

[0030] Specifically, the clamping module 22 includes an electric push rod 221, a clamping plate 222, and a guide roller 223. 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, and more than two guide rollers 223 are arranged on one side of the two clamping plates 222 close to each other. In this embodiment, the two electric push rods 221 are coaxially arranged, and the electric push rod 221 is a telescopic structure that can drive the two clamping plates 222 to approach or separate from each other, so as to clamp color steel plates of different sizes, with better applicability. The clamping plate 222 is a flat plate structure and is vertically arranged. The arranged guide rollers 223 can rotate, so as to reduce the friction between the color steel plate and the clamping plate 222 and make the feeding process proceed smoothly.

[0031] 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, and the electric push rod 221 drives the two clamping plates 222 to approach each other and abut against the outer side wall of the color steel plate. At this time, start the electromagnetic chuck 212, and the magnetic force generated by the electromagnetic chuck 212 adsorbs and fixes the color steel plate on the conveyor belt 211. Then start the first motor 312, and the first motor 312 drives the first lead screw 313 to rotate. The rotation of the first lead screw 313 drives the sliding seat 314 to slide, so as to adjust the position of the moving frame 311, and make both sides of the color steel plate align with the gaps between the two moving frames 311 of one of the cleaning units respectively. Then start the second motor 315, and the second motor 315 drives the second lead screw 316 to rotate. The rotation of the second lead screw 316 drives the two moving frames 311 to approach each other, so that the gaps between the adjacent two grinding rollers 33 and the adjacent two straightening rollers 34 are adapted to the thickness of the color steel plate. Then start the conveyor belt 211, and the conveyor belt 211 drives the color steel plate to move towards the side close to the moving frame 311. During the movement of the color steel plate, it will first contact the cutting wire 352. 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 contact with the inner side wall of the color steel plate along the gap cut by the cutting wire 352, so that the glue loses its viscosity and is easy to remove. And the excess degumming agent will flow into the liquid collection bin 38 below for temporary storage, which is convenient for subsequent treatment. Then the color steel plate will pass through the gap between the adjacent two straightening rollers 34, and the straightening rollers 34 will squeeze and flatten the protrusions and bent parts on the surface of the color steel plate. At the same time, the grinding motor 32 will drive the grinding rollers 33 to rotate to grind the inner side and the outer side of the color steel plate, so as to remove surface rust and other impurities, which is convenient for recycling. And heat will also be generated during the grinding process of the grinding rollers 33, and then heat the color steel plate to eliminate the internal stress to prevent the color steel plate from rebounding.

[0032] In addition, all the components used in this embodiment are commercially available.
