Description

Technical Field

[0001] This invention relates to the field of engineering waste recycling equipment technology, specifically to a high-efficiency recycling and processing equipment for construction waste. Background Technology

[0002] With the acceleration of urbanization, the output of construction waste has increased dramatically. This waste is complex in composition, including concrete, bricks, and reinforcing steel. Converting this waste into reusable aggregates is a crucial way to achieve resource recycling and protect the environment. However, existing recycling technologies still face many challenges in terms of efficiency and processing quality. The vast differences in size and hardness of the waste in its raw state make even initial processing extremely difficult. In the crushing stage, the adaptability of equipment to different materials becomes a major bottleneck. Simultaneously, secondary pollution and incomplete resource recovery during material transfer and discharge are becoming increasingly prominent issues.

[0003] For raw materials with mixed compositions, many machines lack effective pretreatment mechanisms. They often crush metals and non-metals together, which not only increases the difficulty of subsequent metal sorting but also makes it impossible to accurately measure the material flow rate at the beginning of processing, resulting in a lack of data support for the management and efficiency evaluation of the entire production process. Secondly, the crushing gap of traditional crushers is mostly fixed or requires manual adjustment when the machine is stopped. This design is very rigid when dealing with waste materials with uneven hardness. The equipment either frequently clogs because it cannot handle large pieces of high-strength concrete or causes unnecessary energy waste due to over-crushing low-strength bricks, greatly reducing its operational stability and economy.

[0004] In existing technologies, fine metals or valuable impurities remaining in finished aggregates are often ignored when they are output via conveyor belts, resulting in resource waste. Recycling these impurities requires additional manual sorting lines, which is costly. More seriously, the falling and stacking of materials generates a large amount of dust. Existing dust suppression measures, such as spraying, have limited effectiveness and can affect the moisture content of the finished aggregates. Simple dust hoods cannot solve the dust problem at its source, posing a potential threat to the working environment and the surrounding atmosphere. Summary of the Invention

[0020] Please see the appendix Figure 1 - Appendix Figure 6This invention provides a high-efficiency recycling and processing device for construction waste, comprising: a crushing box 1, a support frame 2 fixed to the outside of the crushing box 1, and a hopper 10 penetrating the top of the crushing box 1; a crushing assembly 3, which is mounted on the support frame 2, the crushing assembly 3 including a feeding box 301, a top plate 302 hinged to the top of the feeding box 301, a discharge port 303 penetrating the bottom of the feeding box 301, a plurality of symmetrically arranged hinge blocks 304 fixed to the top of the feeding box 301, connecting rods 305 rotatably mounted on the outer walls of the hinge blocks 304, a fixing frame 306 fixed to the end of the connecting rods 305, a motor 307 fixed to the outer wall of the fixing frame 306, and a crushing roller 30 fixed to the drive end of the motor 307. 8. The end of the crushing roller 308 rotates inside the fixed frame 306; the collecting assembly 4 is located inside the feed box 301, and the collecting assembly 4 includes left and right symmetrical conical plates 401, the outer wall of the conical plates 401 sliding inside the feed box 301; the crushing assembly 5 is located inside the crushing box 1, and is used to further crush the crushed waste; the adjusting assembly 6 is located inside the crushing box 1, and is used to adjust the spacing of the crushing components; the discharge assembly 7 is located through the bottom of the crushing box 1, and is used to discharge the aggregate after multiple crushings; the purification assembly 8 is located on the crushing box 1, and is used to absorb the dust generated during crushing inside the crushing box 1 to prevent dust from overflowing, and the feed box 301 rotates inside. There are two symmetrical rotating rods 309. Multiple cams 313 are fixed to the outer wall of the rotating rods 309. The outer wall of the cams 313 is attached to the bottom end of the connecting rod 305. A handle 310 is fixed to the end of each rotating rod 309. A pawl 311 is fixed to the outer wall of the rotating rod 309. A ratchet 312 is bolted to the outer wall of the feed box 301. The ratchet 312 and the pawl 311 mesh. Rotating the rotating rods 309 first causes the cams 313 to push the connecting rod 305, moving the crushing roller 308 to adjust the distance between the two crushing rollers 308. After the position of the pawl 311 is determined, the ratchet 312 is installed to restrict the position of the pawl 311. A screen 314 is fixed inside the feed box 301. A screen 314 is positioned below the crushing roller 308. A first vibration motor 315 is fixed to the lower surface of the screen 314. An inclined guide pipe 9 passes through the outer side of the feed box 301. The inclined guide pipe 9 is positioned above the hopper 10 and on the lower side of the screen 314. Magnet blocks 403 are fixed to both sides of the conical plate 401. A handle 402 is fixed to the outer wall of the conical plate 401. A controller 405 is fixed to the outer wall of the conical plate 401. A mass sensor 404 is fixed to the lower surface of the conical plate 401. An indicator light 406 is fixed to the outer wall of the conical plate 401. The mass sensor 404 and the controller 405 are electrically connected. The mass sensor 404 and the indicator light 406 are electrically connected.

[0021] Specifically, through the synergistic action of the crushing component 3 and the collecting component 4, intelligent preliminary processing of construction waste is achieved. Operators can observe the contents of the feed hopper 301 via the top plate 302 and rotate the handle 310. Utilizing the locking mechanism of the pawl 311 and ratchet 312, the position of the connecting rod 305 and the fixed frame 306 is precisely adjusted by the rotating rod 309 driving the cam 313, thereby setting the working distance of the crushing roller 308 driven by the motor 307. This design enables adaptive crushing of different waste materials at the source. While the material is being initially crushed, the internal conical plate 401 captures mixed metal substances using its surface magnets 403, achieving initial processing of solid waste and metal. The immediate separation at the initial stage greatly reduces the wear of subsequent crushing equipment and ensures the purity of the finished aggregate. The quality sensor 404 weighs the recovered metal in real time, and the controller 405 automatically lights up the indicator light 406 according to the preset threshold, upgrading the traditional manual inspection to a quantitative and automated management mode. This not only prompts the operator to clean the handle 402 in time, but also provides accurate data support for resource recycling. Subsequently, the first vibration motor 315 drives the screen 314 to vibrate at high frequency, effectively classifying the crushed material. Material with qualified size enters the next process through the discharge port 303, while large-sized particles are guided to the inclined guide pipe 9 and the hopper 10 to prepare for subsequent fine crushing.

The outer wall of 508 is fixed to the outer wall of the crushing box 1. A rotating rod 510 is fixed to the drive end of the reducer 509. Multiple cams 511 are fixed to the outer wall of the rotating rod 510. Symmetrical guide rods 513 are slidably connected to the outer side of the crushing box 1. A crushing plate 515 is fixed to one end of each guide rod 513. The crushing plate 515 is positioned inside the crushing box 1 and fits against the crushing roller 503. A movable plate 512 is fixed to the other end of each guide rod 513. The outer wall of the movable plate 512 fits against the cams 511. Springs 514 are sleeved on the outer wall of each guide rod 513. One end of each spring 514 is fixed to the outer wall of the crushing box 1, and the other end is fixed... A support plate 11 is fixed to the outer wall of the moving plate 512. An arc-shaped guide plate 12 is fixed to the outer wall of the support plate 11. Multiple second vibration motors 13 are fixed to the lower surface of the arc-shaped guide plate 12. The arc-shaped guide plate 12 is located below the crushing plate 515 and the crushing roller 503. A transmission wheel 516 is fixed to the end of the rotating rod 502. A connecting belt 517 is connected to the outer side of the transmission wheel 516. A transmission wheel 518 is connected to the outer side of the connecting belt 517. A rotating rod 519 is fixed inside the transmission wheel 518. The outer wall of the rotating rod 519 rotates inside the crushing box 1. The outer wall of the crushing box 1 is fixed with a second crushing roller 520. The adjusting component 6 includes a fixing block 601. The outer wall of the fixing block 601 is fixed to the outer wall of the crushing box 1. A hydraulic rod 602 is fixed inside the fixing block 601. A sliding block 603 is fixed to the driving end of the hydraulic rod 602. The outer wall of the sliding block 603 slides on the inner side of the crushing box 1. A motor 604 is fixed to the outer wall of the sliding block 603.

The outer wall of the crushing roller 606 is located outside the crushing roller 520. The crushing roller 520 and the crushing roller 606 are located below the arc-shaped guide plate 12.

[0023] Specifically, the precise coordination of crushing component 5 and adjusting component 6 constitutes the core crushing system of the equipment, realizing a multi-stage, adjustable processing flow from coarse to fine crushing. When the material enters the crushing box 1, the rotating rod 502 driven by motor 501 not only drives the crushing roller 503 to rotate and crush, but also drives the cam 511 on the rotating rod 510 through belt 505, transmission wheel 506, drive rod 507 and reducer 509. This cam mechanism drives the crushing plate 515 to reciprocate under the reset action of spring 514 through moving plate 512 and guide rod 513, forming a highly efficient squeezing and impact crushing zone with the crushing roller 503, which can quickly break down large pieces of hard waste. The material, after initial crushing, falls onto the arc-shaped guide plate 12 driven by the second vibration motor 13, and enters evenly into the fine crushing zone composed of crushing roller 2 520 and crushing roller 3 606. The power of crushing roller 2 520 comes from the transmission of rotating rod 1 502 via connecting belt 517. The key is the adjustment component 6, which drives sliding block 603 through external hydraulic rod 602, so that crushing roller 3 606, driven by independent motor 3 604, can smoothly adjust the distance between itself and crushing roller 2 520. This eliminates the cumbersome adjustment required by traditional equipment when stopping the machine, and gives the equipment the ability to dynamically adjust in real time according to the material hardness and output particle size requirements, effectively avoiding the problem of blockage caused by uneven material distribution.

[0024] Please see the appendix Figure 12 - Appendix Figure 15The purification assembly 8 includes a purification chamber 801, the outer wall of which is fixed to the crushing chamber 1. An air pump 802 is fixed to the upper surface of the purification chamber 801.

The connecting plate 805 and the handle 807 are located on the outside of the purification box 801. An air suction pipe 808 passes through the outside of the purification box 801. The outer wall of the air suction pipe 808 passes through the inside of the crushing box 1. Two centrally symmetrical connecting pipes 809 are fixed to the end of the air suction pipe 808.

The upper surface of the connecting frame 812 is fixed to the inner top of the crushing box 1. A support plate 2 14 is fixed to the inner bottom of the crushing box 1. An arc-shaped guide plate 2 15 is fixed to the upper surface of the support plate 2 14. The outer wall of the arc-shaped guide plate 2 15 is positioned above the crushing roller 2 520 and the crushing roller 3 606. The discharge assembly 7 includes a fixing frame 701. The outer wall of the fixing frame 701 is penetrated by... At the bottom of the crushing box 1, a conveyor belt 702 is provided on the inner side of the fixed frame 701. The outer wall of the conveyor belt 702 is located below the arc-shaped guide plate 15. A robotic arm 703 is fixed on the upper surface of the fixed frame 701.

[0025] Specifically, when the final aggregate is guided to the discharge process by the arc-shaped guide plate 215 supported by the support plate 214, the purification component 8 is actively connected. The suction pump 802 generates negative pressure through the suction pipe 803 and the exhaust pipe 804, and drives multiple suction nozzles 811 strategically arranged at key dust-generating points under the support of the connecting frame 812 through the suction pipe 808, the connecting pipe 809 and the diversion pipe 810, so as to efficiently capture the dust diffused during the crushing process into the purification box 801 from the source. The dust-laden airflow passes through the handle 2 807 and the connecting plate 805. After the filter element 806 is replaced, the material is purified, preventing secondary dust pollution during the operation. At the same time, the finished aggregate falls onto the conveyor belt 702 in the fixed frame 701 for conveying. The refining function of the discharge component 7 is activated. The robotic arm 703 drives the connecting block 704, and the cylinder 705 precisely controls the clamping block 706 with the second magnet 707 to perform dynamic inspection and adsorption operations above the conveyor belt 702. This design upgrades the traditional passive discharge to an active secondary purification process, which can capture the last residual metal impurities entrained in the finished aggregate.

[0026] Working principle: After starting the equipment, opening the top plate 302 causes waste to fall into the feed box 301. The operator rotates the handle 310, which drives the pawl 311 to engage and position on the ratchet 312 via the rotating rod 309. This causes the cam 313 to lift the connecting rod 305 and the fixed frame 306, which are rotatably connected by the hinge block 304. This adjusts the distance between the two crushing rollers 308 driven by the motor 307 to perform preliminary crushing of the waste. The crushed material falls onto the screen 314 driven by the first vibrating motor 315 for screening. Qualified material is discharged through the discharge port 303. At the same time, the magnetic block 403 on the conical plate 401 of the collection component 4 adsorbs metal impurities, which are then removed by the mass transfer mechanism. The weight sensor 404 monitors the weight and illuminates the indicator light 406 via the controller 405 to prompt the operator to remove and clean the material using the handle 402. Large particles fall into the hopper 10 through the inclined guide pipe 9 and enter the crushing box 1 fixed by the support frame 2. The material entering the crushing box 1 is driven by the motor 501 to rotate the first rotating rod 502, which in turn drives the first crushing roller 503 to rotate. Simultaneously, the rotation rod 510 is driven by the transmission wheel 504, belt 505, second transmission wheel 506, drive rod 507, and reducer 509 fixed by the support block 508, which in turn drives the second rotating rod 510 to drive the second cam 511, pushing the moving plate 512 and guide rod 513 so that the crushing plate 515 is under the action of the spring 514. Using reciprocating motion, the material undergoes secondary crushing in conjunction with the first crushing roller 503. The material falls onto the arc-shaped guide plate 12, supported by the support plate 11 and driven to vibrate by the second vibration motor 13, and slides evenly towards the adjustment assembly 6. The second crushing roller 520 is driven to rotate by the rotating rod 11 via the transmission wheel 3 516, connecting belt 517, transmission wheel 4 518, and rotating rod 3 519. The hydraulic rod 602 within the adjustment assembly 6 extends from the fixed block 601 to push the sliding block 603, thereby moving the third crushing roller 606 connected to the rotating rod 2 605 driven by the motor 3 604. This adjusts the crushing gap for fine crushing, and the final finished aggregate is passed through the arc-shaped guide plate supported by the support plate 2 14. The guide plate 15 guides the final discharge component 7. During this process, the purification component 8 is activated. The air pump 802 operates through the air extraction pipe 803 and the exhaust pipe 804. The dust is sucked into the purification box 801 by the suction pipe 808, connecting pipe 809, diversion pipe 810 and multiple suction nozzles 811 under the support of the connecting frame 812. The dust is filtered by the filter element 806 that can be pulled out through the handle 807 and the connecting plate 805. The dust is then transported outward on the conveyor belt 702 in the fixed frame 701. The robotic arm 703 above drives the clamping block 706 with the magnet block 707 to move above the material to adsorb the remaining metal through the connecting block 704 and the cylinder 705, thus completing the entire processing process.
