Description

Technical Field

[0001] This invention relates to the field of concrete recycling technology, and more particularly to a concrete waste recycling system. Background Technology

[0002] A concrete waste recycling system is a device or process specifically designed for recycling and processing concrete waste. Its purpose is to transform waste concrete into a reusable resource, thereby saving raw materials, reducing environmental pollution, and generating economic benefits.

[0003] Existing technologies, such as the invention of a rapid treatment and recycling system for concrete waste (authorization number CN113769829B), utilize a fan, recycling pipe, and recycling pool. This allows dust and powder generated during concrete waste crushing to enter the recycling pool and dissolve in water, facilitating the collection of accumulated dust and powder. This, in turn, facilitates the utilization of the powder and finer waste generated during concrete waste crushing, thereby improving the utilization rate of concrete waste.

[0004] Currently, there is a lack of a recycling system that can facilitate multiple compression and crushing of concrete waste to separate ferrous metal materials, such as steel bars and steel plates, and then crush the small pieces again to finally grind them into smaller particles for easy reuse.

[0005] Therefore, in order to address the above problems, a concrete waste recycling system is proposed. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by developing a concrete waste recycling system. This invention facilitates multiple compression and crushing of concrete waste to separate ferrous metal materials. The small pieces formed by compression are then crushed again and finally ground into smaller particles for easy reuse.

[0007] The technical solution to the technical problem solved by the present invention is as follows: The present invention provides a concrete waste recycling system, comprising: a processing box assembly and a first processing assembly; the processing box assembly includes an inlet box, the inlet box being fixedly connected to a crushing box, the crushing box being connected to a grinding box, the inlet box being connected to a protective box, the protective box being connected to symmetrical L-plates, and the symmetrical L-plates being respectively connected to a bottom plate; a converging hood is connected inside the grinding box, and the grinding box and the converging hood form two outlets; the first processing assembly includes a main motor, the inlet box being connected to the main motor, the inlet box bearing being connected to the central shaft of symmetrical crushing rollers, the output shaft of the main motor being connected to the central shaft of one of the crushing rollers, the symmetrical crushing rollers being respectively connected to a set of crushing blades, the upper bearing of the grinding box being connected to the central shaft of symmetrical sorting rollers, the symmetrical sorting rollers being respectively connected to a set of electromagnetic plates, and the bottom bearing of the grinding box being connected to the central shaft of the symmetrical grinding rollers. By employing the first processing component, concrete waste is processed. The crushing roller and crushing blade crush large pieces of concrete into smaller pieces. Some concrete adhering to the surface of steel bars, steel plates and other iron materials is attracted by the electromagnetic plate. When the electromagnetic plate is de-energized, it falls from the outlet, realizing the separation of iron materials. Then, the small pieces of concrete are ground into granules by the grinding roller, realizing the recycling and processing of concrete waste.

[0008] As an optimization, the inlet box bearing is connected to symmetrical transmission gears, which mesh with each other. The central shafts of the symmetrical crushing rollers are respectively connected to power gears, which mesh with corresponding transmission gears.

The inlet box is connected to a protective cover corresponding to the transmission gears, power gears, and upper synchronous belts. The inlet box is provided with corresponding vertical slots for the upper synchronous belts. By using gear meshing and synchronous belt drive, the movement of the crushing rollers, sorting rollers, and grinding rollers is realized, facilitating the recycling and processing of concrete waste.

Adjacent moving plates are vertically distributed, and the square groove plate and the moving plate form a square structure with constantly changing side length. Together with the extrusion hood and the crushing box, they extrude the waste material that has been reduced in size, making it even smaller. In particular, they extrude the concrete adhering to the surface of ferrous materials such as steel bars and steel plates, making the steel bars and steel plates cleaner and easier to collect later.

[0010] As an optimization, the central shaft of the drive gear is connected to a vertical shaft, which in turn is connected to a set of first crushing teeth, which are matched with the convergent cover. The first crushing teeth continue to rotate, further crushing the compressed concrete to facilitate subsequent grinding.

[0011] As an optimization, the fixed end of the swing arm is cross-connected to the telescopic shaft, the vertical shaft is set inside the telescopic shaft, the free end of the telescopic shaft is connected to a U-plate, the U-plate matches the convergence cover, and the U-plate is connected to a set of symmetrical second crushing teeth.

The eccentric parts of the two lower synchronous pulleys on the upper side are respectively connected to second circular blocks, and the two second circular blocks are respectively arranged in the horizontal groove. By arranging the second circular blocks in the horizontal groove, the second crushing teeth can move along the height direction, driving the concrete in the convergence hood to move, which facilitates the crushing of the first crushing teeth.

[0013] As an optimization, an alignment assembly is also included. This assembly comprises two mounting plates and two first sensors. The central axes of the symmetrical sorting rollers are respectively connected to the corresponding mounting plates. The protective box is connected to the two first sensors. Each of the two mounting plates is equipped with a set of evenly distributed second sensors, with the first sensors matching the second sensors. When the second sensor and the first sensor are in the same position, the corresponding electromagnetic plate is de-energized, allowing the ferrous material to fall from the outlet.

[0032] like Figures 1 to 13As shown in Embodiment 1: A concrete waste recycling system includes: a processing box assembly 1 and a first processing assembly 2; the processing box assembly 1 includes an inlet box 11 for receiving large pieces of concrete waste; the inlet box 11 is fixedly connected to a crushing box 16, a primary coarse crushing chamber; the crushing box 16 is connected to a grinding box 17, a secondary fine crushing chamber; the inlet box 11 is connected to a protective box 13, the protective box 13 is connected to symmetrical L-plates 14, and the symmetrical L-plates 14 are respectively connected to a bottom plate 15; the grinding box 17 is internally connected to a convergent hood 18 with an inverted conical liner, and the grinding box 17 and the convergent hood 18 are connected to the bottom plate 15. The cover 18 forms two outlets 19; the first processing component 2 includes a main motor 21, the inlet box 11 is connected to the main motor 21, the inlet box 11 is bearing connected to the central shaft of symmetrical crushing rollers 22, the output shaft of the main motor 21 is connected to the central shaft of one of the crushing rollers 22, and the symmetrical crushing rollers 22 are respectively connected to a set of crushing blades 23 to perform primary shearing and crushing of concrete blocks; the upper bearing of the grinding box 17 is connected to the central shaft of symmetrical sorting rollers 29, and the symmetrical sorting rollers 29 are respectively connected to a set of electromagnetic plates 210. During rotation, the electromagnetic plates 210 are energized to generate a magnetic field, attracting waste steel bars and iron blocks; after power is cut off, the magnetic metal automatically falls off, realizing online iron removal; the bottom bearing of the grinding box 17 is connected to the central shaft of symmetrical grinding rollers 211 to perform secondary roller pressing and grinding on the iron-removed material, which can be directly used as recycled aggregate. By employing the first processing component 2, concrete waste is processed. The crushing roller 22 and crushing blade 23 crush large pieces of concrete into smaller pieces. Some concrete adhering to the surface of steel bars, steel plates, and other ferrous materials is attracted by the electromagnetic plate 210. When the electromagnetic plate 210 is de-energized, the concrete falls from the outlet 19, achieving separation of the ferrous materials. Then, the small pieces of concrete are ground into granules by the grinding roller 211, realizing the recycling and processing of concrete waste. A three-stage processing main channel of "primary crushing + magnetic separation and secondary grinding" is constructed.

[0033] The inlet box 11 is connected to symmetrical transmission gears 25 by bearings. These symmetrical transmission gears 25 mesh with each other. The central shafts of the symmetrical crushing rollers 22 are respectively connected to power gears 24, and the symmetrical power gears 24 mesh with their corresponding transmission gears 25. The central shafts of the symmetrical crushing rollers 22 and the symmetrical sorting rollers 29 are respectively connected to upper synchronous pulleys 26. The two ends of the two upper synchronous belts 27 are respectively wrapped around the corresponding upper synchronous pulleys 26. The central shafts of the symmetrical sorting rollers 29 and the symmetrical grinding rollers 211 are respectively connected to lower synchronous pulleys 28, and the two ends of the two lower synchronous belts 212 are respectively wrapped around the corresponding lower synchronous pulleys 28. A protective cover 12 is connected to the inlet box 11 corresponding to the transmission gears 25, the power gears 24, and the upper synchronous belts 27. The inlet box 11 is provided with corresponding vertical slots for the upper synchronous belts 27. By employing gear meshing and synchronous belt drive, the movement of the crushing rollers 22, sorting rollers 29, and grinding rollers 211 is realized, facilitating the recycling and processing of concrete waste. Synchronous drive from a single motor to four axes is achieved using a "gear + synchronous belt" system, simplifying the transmission chain.

[0034] The system also includes an alignment assembly 4, which comprises two mounting discs 41 and two first sensors 43. The central axes of the symmetrical sorting rollers 29 are respectively connected to the corresponding mounting discs 41. The protective box 13 is connected to the two first sensors 43. Each of the two mounting discs 41 is equipped with a set of evenly distributed second sensors 42, with the first sensors 43 matching the second sensors 42. When the second sensor 42 and the first sensor 43 are in the same position, the corresponding electromagnetic plate 210 is de-energized, allowing ferrous materials to fall from the outlet 19. When the second sensor 42 rotates with the mounting disc 41 and aligns with the first sensor 43, the system records the phase angle and precisely controls the timing of de-energizing the electromagnetic plate 210. After a period of time, the system is energized again. Ferrous impurities are attracted at high points and released when the system rotates to low points.

[0035] The workflow of this embodiment is as follows: Concrete waste is manually or using equipment to be poured into the inlet box 11. The main motor 21 is controlled to rotate. The main motor 21 drives a crushing roller 22 and a power gear 24 to rotate. The power gear 24 drives the transmission gear 25, another power gear 24 and another crushing roller 22 to rotate. The crushing roller 22 drives the crushing blade 23 and the upper synchronous pulley 26 to rotate. The upper synchronous pulley 26 drives the upper synchronous belt 27 to move. The upper synchronous belt 27 drives the lower synchronous pulley 26, the upper lower synchronous pulley 28, the sorting roller 29 and the electromagnetic plate 210 to rotate. The upper lower synchronous pulley 28 drives the lower synchronous belt 212 to move. The lower synchronous belt 212 drives the lower lower synchronous pulley 28 and the grinding roller 211 to rotate.

[0036] The crushing blade 23 crushes concrete waste into smaller pieces, which then fall from the inlet box 11 through the crushing box 16 into the area formed by the electromagnetic plate 210. When the electromagnetic plate 210 is energized, it attracts ferrous materials. The sorting roller 29 drives the mounting plate 41 and the second sensor 42 to rotate. When the second sensor 42 aligns with the first sensor 43, the corresponding electromagnetic plate 210 is de-energized, causing the ferrous materials to fall from the outlet 19. The smaller waste falls into the collecting hood 18 and then between the two grinding rollers 211, where it is ground into granules.

[0037] Example 2: This example further elaborates on Example 1, and also includes a second processing component 3. The second processing component 3 includes a power motor 33. The crushing box 16 is connected to a cross plate 113. The cross plate 113 is connected to an extrusion cover 112. The extrusion cover 112 is connected to a round head cover 111. The power motor 33 is connected to the cross plate 113. The output shaft of the power motor 33 passes through the cross plate 113 and is connected to a drive gear 34. The cross plate 113 is bearing-connected to a driven gear 35. The drive gear 34 meshes with the driven gear 35. The driven gear 35 is connected to a turntable 36. The eccentric part of the turntable 36 is connected to a first circular block 317. The central shaft bearing of the drive gear 34 is connected to a swing arm cross 37. The swing arm cross 37 is provided with a set of sliding grooves 316. The first circular block 317 is placed in the corresponding sliding groove 316, converting continuous rotation into the swing arm cross 37. The reciprocating oscillation; the swing arm cross 37 is rotatably connected to one end of a set of connecting rods 320, and the other end of each connecting rod 320 is rotatably connected to an L-rod 321. The crossbar of each L-rod 321 passes through the crushing box 16, and each L-rod 321 is connected to a square groove plate 319, transforming the reciprocating oscillation into a symmetrical extrusion motion of the square groove plate 319. Two moving plates 318 are respectively arranged in each square groove plate 319, and adjacent moving plates 318 are rotatably connected. The grinding box 17 is provided with horizontal through slots corresponding to the two connecting rods 320. By employing gear meshing, the first circular block 317 is placed in the corresponding slide groove 316, enabling the movement of the square channel plate 319 and the moving plate 318 when the power motor 33 rotates. The adjacent moving plates 318 are vertically distributed, and the square channel plate 319 and the moving plate 318 form a square structure with constantly changing side length. Together with the extrusion cover 112 and the crushing box 16, they extrude the smaller waste material, making it smaller again. In particular, they extrude the concrete adhering to the surface of iron materials such as steel bars and steel plates, making the steel bars and steel plates cleaner and easier to collect later.

[0038] The workflow of this embodiment is as follows: The power motor 33 is controlled to rotate, which drives the drive gear 34 to rotate. The drive gear 34 drives the driven gear 35 and the turntable 36 to rotate. The turntable 36 drives the first circular block 317 to swing in the slide groove 316. The first circular block 317 drives the swing arm cross 37 to swing back and forth. The swing arm cross 37 drives the connecting rod 320 to swing back and forth. The connecting rod 320 drives the L rod 321 to move back and forth. The L rod 321 drives the square groove plate 319 to move back and forth. The square groove plate 319 drives the moving plate 318 to move back and forth and unfold along the square groove plate 319. Together with the extrusion cover 112 and the crushing box 16, it extrudes the smaller waste material and makes it smaller again.

[0039] Example 3: This example further elaborates on Example 2. The central shaft of the drive gear 34 is connected to the vertical shaft 313, and the vertical shaft 313 is connected to a set of first crushing teeth 314. The set of first crushing teeth 314 matches the converging cover 18. The first crushing teeth 314 rotate to further crush the compressed concrete, facilitating subsequent grinding. The first crushing teeth 314 form a shear gap with the inner wall of the converging cover 18, cutting the falling material flow and further reducing the size of the concrete, thus protecting the roller surface.

[0040] The workflow of this embodiment is as follows: The drive gear 34 drives the vertical shaft 313 and the first crushing tooth 314 to rotate. The first crushing tooth 314 rotates inside the converging cover 18 to crush the waste material again.

[0041] Example 4: This example further elaborates on Example 3. The swing arm cross 37 is connected to the fixed end of the telescopic shaft 38. The vertical shaft 313 is disposed inside the telescopic shaft 38. The free end of the telescopic shaft 38 is connected to a U-plate 39. The U-plate 39 matches the convergent cover 18. The U-plate 39 is connected to a set of symmetrical second crushing teeth 315. The second crushing teeth 315 reciprocate to strike the falling concrete, reducing its size for easier subsequent processing.

[0042] The grinding box 17 is provided with symmetrical vertical grooves 110. One end of a lifting rod 310 is respectively installed in each of the symmetrical vertical grooves 110. The free end bearing of the telescopic shaft 38 is connected to the lifting rod 310. Anti-detachment plates 312 are respectively connected to both ends of the lifting rod 310. One anti-detachment plate 312 is connected to an L-mount bracket 311. The L-mount bracket 311 is connected to a horizontal groove 32. Second circular blocks 31 are respectively connected to the eccentric points of the two lower synchronous pulleys 28 on the upper side. The two second circular blocks 31 are respectively installed in the horizontal groove 32. By installing the second circular blocks 31 in the horizontal groove 32, the second crushing teeth 315 move along the height direction, driving the concrete in the convergence cover 18 to move, facilitating the crushing by the first crushing teeth 314.

[0043] The workflow of this embodiment is as follows: The swing arm cross 37 drives the telescopic shaft 38, U-plate 39, and second crushing tooth 315 to reciprocate. The upper lower synchronous wheel 28 drives the second round block 31 to swing in the horizontal groove 32. The second round block 31 drives the horizontal groove 32 to move back and forth. The horizontal groove 32 drives the L mounting bracket 311 and anti-detachment plate 312 to move back and forth. The anti-detachment plate 312 drives the lifting rod 310 to move back and forth in the vertical groove 110. The lifting rod 310 drives the free end of the telescopic shaft 38 to move back and forth along the height direction. The telescopic shaft 38 drives the U-plate 39 and second crushing tooth 315 to move back and forth along the height direction, causing some waste material to rise and contact the first crushing tooth 314 again, resulting in a better crushing effect.

[0044] This device uses a first processing component 2 to process concrete waste and separate ferrous metal materials. The crushing roller 22 and crushing blade 23 work together to crush large pieces of concrete into smaller pieces. Some concrete adhering to the surface of ferrous materials such as steel bars and steel plates is attracted by the electromagnetic plate 210. When the second sensor 42 and the first sensor 43 are in the same position, the corresponding electromagnetic plate 210 is de-energized, allowing the ferrous materials to fall from the outlet 19 and achieve separation of the ferrous materials. Then, the small pieces of concrete are ground into granules by the grinding roller 211, realizing the recycling and processing of concrete waste, improving work efficiency, and achieving comprehensive utilization of concrete waste.

[0045] When the power motor 33 of this device rotates, the square channel plate 319 and the moving plate 318 reciprocate. The adjacent moving plates 318 are vertically distributed, and the square channel plate 319 and the moving plate 318 form a square structure with a constantly changing side length. Together with the extrusion shroud 112 and the crushing box 16, they extrude the smaller waste material, making it smaller again. In particular, they extrude the concrete adhering to the surface of iron materials such as steel bars and steel plates, making the steel bars and steel plates cleaner and easier to collect later. The first crushing tooth 314 keeps rotating and crushes the extruded concrete again, which is convenient for subsequent grinding. The second crushing tooth 315 moves along the height direction, driving the concrete in the convergence shroud 18 to move, which is convenient for the first crushing tooth 314 to crush.

[0046] Although the specific embodiments of the invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the invention. Based on the technical solutions of the invention, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the invention.
