Abstract
Description
Technical Field
[0001] This invention relates to the field of solid waste utilization, and more particularly to a device for recycling construction waste. Background Technology
[0002] In road engineering, the reuse of construction waste is an important practice for promoting resource recycling and sustainable development. Its core reuse types include waste concrete, waste asphalt, slag, waste steel, and waste wood. Waste concrete, after crushing and screening, can be made into recycled aggregate, replacing natural sand and gravel for road base courses or permeable brick production. Waste asphalt mixtures, by incorporating recycling agents and new asphalt, can be used to prepare recycled asphalt concrete with performance close to conventional materials. Waste steel, through sorting and recycling, can be made into new steel; over 80% of the steel bars in the international market rely on recycled waste steel. Waste wood, through processing into recycled boards or papermaking raw materials, achieves internal resource recycling and reduces deforestation. The reuse of these wastes not only creates significant economic value but also brings outstanding environmental benefits.
[0003] Existing construction waste recycling facilities have the following shortcomings:
[0004] 1. Crushing and Screening: Crushing efficiency is low, lacking a pre-crushing stage for large waste materials, leading to increased pressure on subsequent processing and low processing efficiency. Screening is incomplete; the screening device design is simple and cannot achieve efficient, multi-stage dynamic screening.
[0005] 2. Regarding the separation of metal impurities: The separation effect is poor. Existing technology lacks effective metal separation devices in the critical path before the diverted waste enters subsequent processing, affecting reuse value and safety performance. Material conveying is not smooth; no device is installed during the metal separation process to ensure the smooth entry of non-metallic materials into subsequent processing stages, affecting the continuity of the overall processing flow.
[0006] 3. Molding and Discharge: Molding efficiency is low; existing equipment cannot directly compress qualified waste materials into dense construction waste blocks, increasing processing steps and time. Discharge automation is low; the discharge device has a simple structure and limited function, requiring significant manual intervention and resulting in low efficiency.
[0007] 4. Process optimization and resource utilization: The process is not compact; the existing equipment's process design is not compact and reasonable enough, failing to achieve continuous and automated processing of construction waste, resulting in low processing efficiency. Resource utilization is low; it cannot maximize the utilization of different components in the waste and achieve efficient resource recycling through multi-stage screening, metal recovery, ineffective material recycling, effective material briquetting, and waste collection. Summary of the Invention
[0008] To address the problems existing in the background technology, a construction waste recycling device is proposed. Through an innovative multi-stage linkage design, the automation level, sorting accuracy and resource recovery rate of construction waste recycling are significantly improved. The recycled material blocks produced are of high purity and good quality, while effectively reducing energy consumption and secondary pollution in the processing process, providing an efficient and reliable solution for the recycling of construction waste.
[0009] This invention proposes a construction waste recycling device, comprising a base, a conveying box, a feeding component, a bulk material bin, a diversion channel, a metal recycling cylinder, a return channel, and a discharge component. Two sets of bases are arranged on the left and right sides; the conveying box is located on one set of bases, with feeding at the bottom and discharging at the top; the bulk material bin is located on the other set of bases, with a cutting component at the top and a pushing component at the bottom. The cutting and pushing components work together to compress the waste into blocks conforming to building material standards through mechanical pressure, achieving both waste reduction and resource recovery; and to cut the waste into smaller pieces to meet the diversion requirements through cutting force. The diversion channel connects the conveying box and the bulk material bin. One end of the built-in diversion component feeds the waste through the conveying box, and after diverting the waste, the other end sends the undiverted waste into the bulk material bin. One end of the metal recycling bin is connected to the main material bin, and the other end is connected to the diversion channel via a recycling pipe. The diverted waste flows through this path, and the remaining waste after the metal components are recovered returns to the main material bin, finally forming blocks that meet building material standards. The return channel is located below the diversion channel, connecting the conveyor box and the main material bin. It serves two purposes: firstly, it allows undiverted waste to enter and return to the conveyor box, and secondly, it allows the formed building waste blocks to enter. The discharge component is installed through the bottom of the return channel. It assists in the horizontal movement of undiverted waste by rotation, and secondly, it moves the formed building waste blocks out of the return channel by lifting.
[0010] Preferably, the diversion channel includes a connecting sleeve connecting the conveying box and the material box respectively, a connecting ring connected to the connecting sleeve, and a connecting cylinder connecting the two sets of connecting rings; the diversion assembly includes a double-layer drive ring structure located between the two sets of connecting rings; the double-layer drive ring structure includes an outer ring frame fixed to the inner wall of the connecting cylinder and an inner ring frame rotatably disposed inside the outer ring frame; the diversion cylinder is disposed inside the inner ring frame and rotates synchronously with it, with both ends extending into the connecting sleeves on the corresponding sides and communicating with the rotating sleeve, and a diversion cavity communicating with the recovery pipe is left between the diversion cylinder and the connecting cylinder; the rotating sleeve rotatably connects to the connecting sleeve, one set communicating with the conveying box and the other set communicating with the material box.
[0011] Preferably, the outer ring frame divides the diversion chamber into independent diversion chambers; the diversion cylinder is set with different diversion levels for different diversion chambers, and the waste is classified and processed according to the particle size to improve resource utilization efficiency; the feed end of the recycling pipe is connected to the diversion chamber one by one.
[0012] Preferably, the top of the outer ring frame is provided with a cleaning roller for cleaning the diversion cylinder, and the sides are provided with extrusion frames for pressing and pushing the diverted waste material downwards.
[0013] Preferably, the metal recovery cylinder uses magnetic separation technology to recover metal components.
[0014] Preferably, a mounting frame is provided on the top of the material box; the cutting assembly includes a lifting drive unit located on the mounting frame; the lifting end of the lifting drive unit extends into the material box and connects to the cutting plate; the cutting plate is provided with staggered hollow grooves one and two, and is also provided with drive unit one and drive unit two, with lifting plate one and lifting plate two arranged in parallel above the cutting plate; the lifting plate one is driven by drive unit one to move up and down above the cutting plate to control the cutting blade one at the bottom of the lifting plate one to enter and exit hollow groove one, and the lifting plate one is provided with hollow groove three corresponding to hollow groove two; the lifting plate two is driven by drive unit two to move up and down above the lifting plate one to control the cutting blade two at the bottom of the lifting plate two to enter and exit hollow groove three and hollow groove one.
[0015] Preferably, a discharge port is provided at the bottom of the return channel; the discharge assembly includes electric slide rails located on the bases on both sides; the lifting plate is driven by the electric slide rails to rise and fall below the discharge port, and a fixed return frame and a rotating return frame rotatably connected to the left and right sides of the fixed return frame are provided at the upper end of the lifting plate; limit frames are provided on the front and rear sides of the fixed return frame; and push rollers are provided on the fixed return frame and the rotating return frame along the direction of waste movement.
[0016] Preferably, when the fixed return frame and the rotating return frame are at 180 degrees, they form an auxiliary plane; when the fixed return frame and the rotating return frame are at 90 degrees, the rotating return frame and the limiting frame form a square limiting structure.
[0017] Compared with the prior art, the present invention has the following beneficial technical effects:
[0018] This invention first employs a feeding mechanism for initial cutting. An electric cutting blade holder within the feeding hopper pre-crushes large pieces of waste, reducing the burden on subsequent processing. Next, a diversion channel is used for graded fine screening. An inclined, vibrating, multi-aperture diversion cylinder, combined with a double-layer drive ring and independent diversion chamber design, achieves efficient, multi-stage (by size) dynamic screening of waste during transport. Smaller waste is preferentially diverted, while larger waste is deferred for subsequent processing, resulting in more thorough screening. Then, a secondary precision cut is performed using a full-material bin. The complex and sophisticated pressure-cutting assembly, through the coordinated and alternating actions of the pressure-cutting plate, lifting plate, and staggered cutting blades, powerfully and precisely cuts large / irregular pieces of undiverted waste, ensuring that the material size meets forming requirements and reducing ineffective recycling.
[0019] In the aforementioned construction waste recycling process, the metal recycling cylinder, positioned at the critical path before the diverted waste enters the material collection bin, effectively adsorbs metal impurities from the separated fine materials, improving reuse value and safety. The material collection bin features a cutting assembly; after the cutting mode, the cutting blade retracts, seamlessly switching to a pressing mode to directly compress the diverted fine materials into denser construction waste blocks, facilitating transportation and reuse. Undiverted / uncut waste is automatically returned to the conveyor box via a return channel for re-screening, forming a closed-loop processing system, reducing manual intervention and ensuring thorough material processing. The formed waste blocks are then moved out via the return channel by a fixed / rotating return frame, push rollers, limit frame, and lifting plate. The discharge assembly serves a dual purpose (conveying return material and removing finished products), with an ingenious structure and a high degree of automation.
[0020] Furthermore, the filter screen design at the top of the hollow base effectively collects dust, debris, and waste liquid generated during processing, reducing environmental pollution, keeping the work area clean, and facilitating centralized treatment. The cleaning roller design automatically cleans the screen holes of the diversion cylinder, preventing clogging, maintaining screening efficiency, and reducing downtime for maintenance. The extrusion frame helps push the screened fines into the recovery pipe, preventing accumulation in the diversion chamber.
[0021] The entire process of the device includes feeding, pre-cutting, lifting, screening, metal recovery, precision cutting / forming, and diversion / discharge. It is compact and efficient, achieving continuous and automated processing of construction waste. Through multi-stage screening, metal recovery, recycling of ineffective materials, briquetting of effective materials, and waste collection, it maximizes the utilization of different components in the waste, truly achieving "complete utilization" and providing an efficient and reliable solution for the reuse of construction waste.

[0032] Example 1: This invention proposes a device for recycling construction waste, such as... Figures 1-3As shown, the system includes a base 1, a conveyor box 2, a feeding component 16, a material collection box 3, a diversion channel 4, a metal recycling cylinder 6, a return channel 7, and a discharge assembly 8. Two sets of bases 1 are arranged on the left and right sides. The conveyor box 2 is located on one set of bases 1, with material fed from the bottom and fed upwards via a built-in feeding component 10. The feeding component 16 is located at the inlet of the conveyor box 2, performing initial cutting of the construction waste. The material collection box 3 is located on the other set of bases 1, with a cutting component 9 at the top and a pushing component 11 at the bottom. The cutting component 9 and the pushing component 11 work together to further cut and move or shape the construction waste. The diversion channel 4 connects the conveyor box 2 and the material collection box 3. One end of the built-in diversion component 13 feeds material through the conveyor box 2, and after diverting the waste, the other end sends the undiverted waste into the material collection box 3. Material bin 3; one end of metal recycling cylinder 6 is connected to the solid material bin 3, and the other end is connected to the diversion channel 4 through recycling pipe 5. The diverted waste is diverted through this path and then enters the metal recycling cylinder 6 and the solid material bin 3, and finally forms a construction waste block; the return channel 7 is located below the diversion channel 4 and is connected between the conveying box 2 and the solid material bin 3. On the one hand, it allows undiverted waste to enter and return to the conveying box 2, and on the other hand, it allows the formed construction waste block to enter; the discharge component 8 is installed through the bottom of the return channel 7. On the one hand, it assists the undiverted waste to move horizontally by rotation, and on the other hand, it moves the formed construction waste block out of the return channel 7 by lifting.
[0033] like Figure 4 As shown, the feeding component 16 includes a feeding hopper 17; the feeding hopper 17 is connected to the feeding port of the conveying box 2, and an electric cutting tool holder 14 for preliminary cutting is provided inside; the electric cutting tool holder 14 is positioned opposite to the feeding port.
[0034] It should be further noted that a feed gate is provided at the feed inlet.
[0035] Workers feed construction waste into the feed hopper 17, and the electric cutting blade holder 14 rotates, cutting the construction waste and pushing it through the feed inlet into the conveyor box 2. Through the alignment design of the electric cutting blade holder 14 and the feed inlet, large pieces of construction waste are forcibly cut and pre-crushed, effectively avoiding feed blockage; the inclined feed hopper 17 combined with the rotating blades forms a directional thrust, significantly improving the initial processing efficiency.
[0036] like Figure 3 As shown, the feeding component 10 is a spiral pusher, which transports the material from the bottom to the top by rotating.
[0037] like Figure 5As shown, the diversion channel 4 includes a connecting sleeve 402 connecting the conveying box 2 and the material collection box 3 respectively, a connecting ring 403 connected to the connecting sleeve 402, and a connecting cylinder 401 connecting the two sets of connecting rings 403. The diversion assembly 13 includes a double-layer drive ring structure located between the two sets of connecting rings 403. The double-layer drive ring structure includes an outer ring frame 1304 fixed to the inner wall of the connecting cylinder 401 and an inner ring frame 1305 rotatably disposed inside the outer ring frame 1304. The diversion cylinder 1302 is disposed inside the inner ring frame 1305 and rotates synchronously with it. Both ends extend into the corresponding side of the connecting sleeve 402 and connect to the rotating sleeve 1301. A diversion cavity connecting to the recovery pipe 5 is left between the diversion cylinder 1302 and the connecting cylinder 401. The rotating sleeve 1301 rotatably connects to the connecting sleeve 402, one set connecting to the conveying box 2 and the other set connecting to the material collection box 3.
[0038] It should be further explained that a vibrator is installed on the connecting cylinder 401; the diverting cylinder 1302 is inclined, with the high end connected to the conveying box 2 and the low end connected to the material box 3; by setting up vibration and inclined screening, the screening efficiency is made more efficient.
[0039] The diverter cylinder 1302 has one end for feeding and one end for discharging. As the waste material moves within the diverter cylinder 1302, the cylinder rotates to screen the material. Waste material that passes through the diverter enters the diversion chamber and is diverted from the waste material. Waste material that does not pass through the diverter enters the material collection box 3 for further cutting processing.
[0040] It should be further explained that the outer ring frame 1304 divides the diversion chamber into independent diversion chambers; the diversion cylinder 1302 is set with different diversion levels for different diversion chambers; the feed end of the recovery pipe 5 is connected to the diversion chamber one by one, the discharge end is inclined downwards, connected to the metal recovery cylinder 6 and equipped with a valve.
[0041] By setting multiple screening levels, smaller waste materials enter the corresponding recycling pipe 5 first, followed by larger waste materials. By setting a discharge time difference, waste materials of different sizes enter the material collection box 3 separately. Undiverted waste materials are returned to the conveyor box 2 and diversion channel 4 after secondary cutting for further screening, while diverted waste materials are shaped and removed. A double-layer drive ring structure (outer ring frame 1304 + inner ring frame 1305) supports the multi-stage rotation screening of the diversion cylinder 1302. Combined with high-frequency vibration from the vibrator, waste materials of different sizes roll in layers within the inclined channel, improving screening efficiency. The cleaning roller 1306 cleans the screen holes in real time to prevent clogging, and the extrusion frame 1303 directionally pushes the diverted waste materials to the recycling pipe 5, reducing residue.
[0042] It should be further explained that the top of the outer ring frame 1304 is provided with a cleaning roller 1306 for cleaning the diversion cylinder 1302, and the sides are provided with extrusion frames 1303 for pressing and pushing the diverted waste material.
[0043] It should be further explained that the cleaning roller 1306 rotates through the outer ring frame 1304 and cleans the screen holes of the diverter 1302 by means of bristles on its surface.
[0044] The extrusion frame 1303 rotates through the outer ring frame 1304, and extrusion plates are set on both sides to seal the upper end of the diversion chamber on the one hand, and push the diverted waste towards the recycling pipe 5 on the other hand.
[0045] like Figure 6 As shown, the metal recycling cylinder 6 includes a cylinder body; one end of the cylinder body is connected to the recycling pipe 5, and the other end is connected to the side wall of the material collection box 3; the magnetic separator 12 and the pusher 15 are coaxially connected and located inside the cylinder body; the magnetic separator 12 is located on the side of the recycling pipe 5; the pusher 15 is located on the side of the material collection box 3; before entering the material collection box 3, the waste material is magnetically intercepted to ensure the efficiency of recycling. The coaxial linkage design of the magnetic separator 12 and the pusher 15 enables the metal-containing waste material to continuously adsorb iron impurities during the spiral propulsion process inside the cylinder, achieving metal separation; the pusher 15 simultaneously pushes the non-metallic waste material into the material collection box 3, avoiding secondary mixing and pollution.
[0046] like Figure 7 As shown, a mounting bracket 301 is provided on the top of the material box 3; the pressure cutting assembly 9 includes a lifting drive 901 located on the mounting bracket 301; the lifting end of the lifting drive 901 extends into the material box 3 and connects to the pressure cutting plate 902; the pressure cutting plate 902 is provided with staggered hollow grooves 903 and 910, and also with drive components 909 and 908; a lifting plate 905 and a lifting plate 904 are arranged parallel to each other above the pressure cutting plate 902; the lifting plate 905... Driven by a drive component 909, the lifting plate 905 moves up and down above the cutting plate 902 to control the cutting blade 906 at the bottom of the lifting plate 905 to enter and exit the slot 903. The lifting plate 905 is provided with a slot 911 corresponding to the slot 910. The lifting plate 904 is driven by a drive component 908 to move up and down above the lifting plate 905 to control the cutting blade 907 at the bottom of the lifting plate 904 to enter and exit the slot 911 and the slot 903.
[0047] It should be further explained that the lifting drive component 901 is a cylinder, the cylinder body is located outside the material box 3 and is fixed by the mounting bracket 301, and the end of the telescopic rod is connected to the pressure cutting plate 902; both drive component one 909 and drive component two 908 are combined structures of screw and motor, which drive the lifting plate one 905 and lifting plate two 904 to lift independently.
[0048] During waste material cutting, the pressure cutting plate 902 drives the lifting plates 905 and 904 to descend synchronously. Then, the cutting blades 906 and 907 alternately extend from the slots 903 and 910 to cut the waste material at the bottom. The slots 903 / 910 of the pressure cutting plate 902 and the cutting blades of the lifting plates 905 / 904 form an interlaced dynamic cutting mesh. The lifting and lowering of the blades are independently controlled by the drive components 909 and 908, achieving precise bidirectional cutting of the waste material and improving the uniformity of crushing. During pressing and shaping, the cutting blades 906 and 907 retract, and the pressure cutting plate 902 forms a complete pressing plane, pressing down on the waste material to shape it and ensuring the density of the waste block.
[0049] like Figure 3 As shown, the pushing assembly 11 includes a drive box and a pushing plate that is driven to move horizontally by the drive box; the pushing plate is opposite to the feed end of the return channel 7. By moving the pushing plate, the waste material can be pushed into the return channel 7.
[0050] like Figure 8 As shown, a discharge port is provided at the bottom of the return channel 7; the discharge assembly 8 includes electric slide rails 805 located on the bases 1 on both sides; the lifting plate 801 is driven by the electric slide rails 805 to rise and fall below the discharge port; a fixed return frame 802 and a rotating return frame 803 rotatably connected to the left and right sides of the fixed return frame 802 are provided at the upper end of the lifting plate 801; a limiting frame 804 is provided on the front and rear sides of the fixed return frame 802; a push roller 806 is provided on the fixed return frame 802 and the rotating return frame 803 along the direction of waste material movement; when the fixed return frame 802 and the rotating return frame 803 are at 180 degrees, the auxiliary plane formed by them matches the discharge port; when the fixed return frame 802 and the rotating return frame 803 are at 90 degrees, the rotating return frame 803 and the limiting frame 804 form a square limiting structure.
[0051] Undiverted waste material is cut and pushed into return channel 7 by the movement of the pusher plate. The waste material moves with the pusher roller 806 through return channel 7 and enters conveyor box 2 for further screening. Diverted formed waste blocks are pushed into return channel 7 by the movement of the pusher plate. The waste material moves with the pusher roller 806 and falls onto the fixed return frame 802. The rotating return frame 803 flips over, forming a square limiting structure with the limiting frame 804. The lifting plate 801 moves down, removing the waste block. The hinged design of the fixed return frame 802 and the rotating return frame 803 allows for angle switching controlled by the electric slide rail 805. When horizontally 180°, the pusher roller 806 assists in waste material circulation; when flipped 90°, the limiting frame 804 forms a rigid support, working with the lifting plate 801 to achieve damage-free removal of the formed waste block. This dual-purpose machine reduces equipment complexity.
[0052] like Figure 9As shown, the base 1 is hollow, and a recycling port connected to the conveying box 2 or the material box 3 is set on the top; a filter screen 101 is set on the recycling port; solid-liquid separation is achieved through the filter screen 101 on the top of the hollow base 1, and waste liquid, dust and debris generated during cutting are collected simultaneously to reduce environmental pollution; the modular base design facilitates regular cleaning and improves the sustainable operation capability of the device.
[0053] Example 2: Based on the construction waste recycling device in Example 1, this example proposes a construction waste recycling method, the steps of which are as follows:
[0054] S1. The staff put the construction waste into the feed hopper 17, the electric cutting blade holder 14 rotates, the blade cuts the construction waste, pushes it through the feed inlet and into the conveyor box 2;
[0055] S2, the feeding component 10 is used to transport the material from the bottom to the top by rotating;
[0056] S3. The diverter 1302 has one end for feeding and one end for discharging. As the waste moves within the diverter 1302, the diverter 1302 rotates and grades the waste for screening. By setting multiple screening levels, small-sized waste enters the corresponding recycling pipe 5 first, and large-sized waste enters the corresponding recycling pipe 5 later. Undiverted waste enters the main material box 3 first.
[0057] S4. The pressure cutting plate 902 drives the lifting plate 1 905 and the lifting plate 2 904 to descend synchronously. Then, the cutting blade 1 906 and the cutting blade 2 907 extend alternately from the hollow groove 1 903 and the hollow groove 2 910 to cut the waste material at the bottom that has not been diverted.
[0058] S5. The cut waste material is pushed into the return channel 7 by the movement of the pusher plate; the waste material moves through the return channel 7 with the pusher roller 806 and enters the conveyor box 2 so that it can re-enter the screening cycle.
[0059] S6. The diverted waste material is first magnetically intercepted by metal substances before entering the material bin 3.
[0060] S7. The upper cutting blades 906 and 907 retract, and the bottom of the pressure plate 902 forms a pressing plane, pressing down the waste material to shape it.
[0061] S8. The formed waste block is pushed into the return channel 7 by the movement of the pusher plate, and falls on the fixed return frame 802 as the pusher roller 806 moves. The return frame 803 is rotated and flipped, forming a square limiting structure with the limiting frame 804.
[0062] S9, the lifting plate 801 moves down, and the waste block can be removed;
[0063] S10. Repeat the above process for the secondary diversion and undiverted waste materials until all waste materials are formed and removed.
[0064] S11. Waste liquid, powder, and debris from the waste treatment process enter the base 1. The base 1 is cleaned after the treatment is completed.
[0065] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
