Description

Technical Field

[0001] The present invention relates to the field of solid waste utilization, in particular to a construction waste recycling device. Background Art

[0002] In road construction, the reuse of construction waste is a key practice in promoting resource recycling and sustainable development. Core recycling methods include waste concrete, waste asphalt, slag, scrap steel, and waste wood. Waste concrete, after crushing and screening, can be made into recycled aggregate, replacing natural sand and gravel for use in road bases or permeable brick production. Waste asphalt mixtures can be mixed with regeneration agents and new asphalt to produce recycled asphalt concrete with properties similar to those of conventional materials. Scrap steel can be sorted and recycled into new steel; over 80% of rebar in the international market relies on recycled scrap steel. Waste wood can be processed into recycled board materials or papermaking raw materials, achieving internal resource recycling and reducing deforestation. The reuse of these waste materials not only creates significant economic value but also brings outstanding environmental benefits.

[0003] The existing construction waste recycling devices have the following deficiencies:

[0004] 1. Crushing and screening: Low crushing efficiency and a lack of pre-crushing for large waste blocks increase the pressure on subsequent processing and result in low processing efficiency. Screening is incomplete and the screening device is simple in design, making it impossible to achieve efficient, multi-stage dynamic screening.

[0005] 2. Metal impurity separation: The separation effect is poor. Existing technologies lack effective metal separation equipment at the critical path before diverted waste enters subsequent processing, affecting its reuse value and safety performance. Material transportation is not smooth. During the metal separation process, there is no equipment to ensure that non-metallic materials can smoothly enter subsequent processing links, affecting the continuity of the overall processing process.

[0006] 3. Forming and discharging: The forming efficiency is low. The existing equipment cannot directly press the waste that meets the requirements into a compact structure of construction waste blocks, which increases the processing steps and time. The discharging automation level is low. The discharging device has a simple structure and a single function, requiring a lot of manual intervention and low efficiency.

[0007] 4. Process Optimization and Resource Utilization: The process is not compact and the process design of the existing equipment is not compact and reasonable enough to achieve continuous and automated processing of construction waste, resulting in low processing efficiency. Resource utilization is low, and it is impossible to maximize the utilization of different components in the waste through multi-stage screening, metal recovery, waste material recycling, effective material briquetting, and waste chip collection to achieve efficient resource recycling. Summary of the Invention

[0008] In response to the problems existing in the background technology, a construction waste recycling device is proposed. Through the innovative multi-level linkage design, the degree of automation, sorting accuracy and resource recovery rate of construction waste recycling processing are significantly improved. The recycled material blocks produced are of high purity and good quality. At the same time, the energy consumption and secondary pollution in the processing process are effectively reduced, providing an efficient and reliable solution for the recycling of construction waste.

[0009] The present invention proposes a construction waste recycling device, including a base, a conveying box, a feed piece, a material box, a diversion channel, a metal recovery cylinder, a return channel and a discharge assembly. Two groups of bases are provided, one on the left and one on the right; the conveying box is located on one group of bases, with feeding at the lower end and discharging at the upper end; the material box is located on the other group of bases, with a pressing and cutting assembly on the top and a pushing assembly on the bottom; under the cooperation of the pressing and cutting assembly and the pushing assembly, on the one hand, the waste is compressed into blocks that meet the building material standards through mechanical pressure, thereby achieving reduction and resource utilization; on the other hand, the waste is cut into smaller pieces through cutting force, so that its size meets the diversion requirements. The diversion channel is connected between the conveying box and the material box, and one end of the built-in diversion assembly feeds the material through the conveying box. After diverting the waste, the other end feeds the undiverted waste into the material box. One end of the metal recovery drum is connected to the bulk bin, and the other end is connected to the diversion channel through a recovery pipe. The diverted waste is diverted along this path. After the metal components are recovered, the remaining waste enters the bulk bin and is finally formed into blocks that meet building material standards. The return channel is located below the diversion channel and connected between the conveyor box and the bulk bin. It allows undiverted waste to enter and return to the conveyor box, and also allows formed construction waste blocks to enter. The discharge assembly is set through the bottom of the return channel. It not only assists the horizontal movement of undiverted waste by rotating, but also removes the formed construction waste blocks from the return channel by lifting.

[0010] Preferably, the diversion channel includes a connecting sleeve respectively connecting the conveying box and the whole material box, a connecting ring connected to the connecting sleeve and a connecting cylinder connected between the two groups of connecting rings; the diversion assembly includes a double-layer drive ring structure located between the two groups of connecting rings; the double-layer drive ring structure includes an outer ring frame fixed on the inner wall of the connecting cylinder and an inner ring frame rotatably arranged inside the outer ring frame; the diversion cylinder is arranged in the inner ring frame and rotates synchronously with it, and the two ends extend into the connecting sleeves on the corresponding sides respectively, and are connected to the rotating sleeve, and a diversion cavity connected to the recovery pipeline is left between the diversion cylinder and the connecting cylinder; the rotating sleeve rotatably connects the connecting sleeve, one group is connected to the conveying box, and the other group is connected to the whole material box.

[0011] Preferably, the outer ring frame divides the diversion cavity into independent diversion chambers; the diversion cylinder sets different diversion levels corresponding to different diversion chambers, and classifies and processes the waste according to its particle size to improve resource utilization efficiency; the feed end of the recovery pipeline is connected to the diversion chamber one by one.

[0012] Preferably, a cleaning roller for cleaning the diverter cylinder is provided on the top of the outer ring frame, and an extrusion frame for pressing down the diverted waste is provided on both sides.

[0013] Preferably, the metal recovery drum uses magnetic separation technology to recover metal components.

[0014] Preferably, a mounting frame is provided on the top of the whole material box; the pressing and cutting assembly includes a lifting drive member located on the mounting frame; the lifting end of the lifting drive member extends into the whole material box and is connected to the pressing and cutting plate; the pressing and cutting plate is provided with staggered hollow grooves 1 and hollow grooves 2, and also provided with drive member 1 and drive member 2, and lifting plate 1 and lifting plate 2 are arranged in parallel above the pressing and cutting plate; lifting plate 1 is driven by drive member 1 to move up and down above the pressing and cutting plate to control the cutting knife 1 at the bottom of lifting plate 1 to enter and exit hollow groove 1, and lifting plate 1 is provided with hollow groove 3 corresponding to hollow groove 2 one to one; lifting plate 2 is driven by drive member 2 to move up and down above lifting plate 1 to control the cutting knife 2 at the bottom of lifting plate 2 to enter and exit hollow groove 3 and hollow groove 1.

[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, the fixed return frame and the rotating return frame form an auxiliary plane when they are 180 degrees apart; when the fixed return frame and the rotating return frame are 90 degrees apart, 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] The present invention first sets up a feed piece for preliminary cutting, and the electric cutting tool holder in the feed hopper pre-crushes large pieces of waste to reduce the pressure of subsequent processing. Then, the diversion channel is used for graded fine screening. The multi-aperture diversion cylinder with a tilted setting and a vibrator, combined with the double-layer drive ring and independent diversion chamber design, realizes efficient, multi-stage (by size) dynamic screening of waste during transportation. Small-sized waste is diverted first, and large-sized waste is delayed for subsequent processing, and the screening is more thorough. Then, the whole material box is used for secondary fine cutting. The structure of the pressing and cutting assembly is complex and sophisticated. Through the coordinated and alternating actions of the pressing and cutting plate, the lifting plate and the staggered cutting knife, the large / irregular waste that has not been diverted can be powerfully and precisely cut for the second time, ensuring that the material size meets the molding requirements and reducing invalid cycles.

[0019] During the above-mentioned construction waste recycling process, the metal recovery drum is set on the key path before the diverted waste enters the whole material box through magnetic separation interception, which can effectively absorb the metal impurities in the sorted fine materials, thereby improving the reuse value and safety performance. The whole material box is equipped with a pressing and cutting component. After the cutting mode, the cutting knife retracts, and it can be seamlessly switched to the pressing mode, and the diverted fine materials are directly pressed into a more compact construction waste block for easy transportation and reuse. The undiverted / uncut waste is automatically returned to the conveying box through the return channel for re-screening, forming a closed processing loop, reducing manual intervention, and ensuring that the materials are fully processed. The molded waste blocks are removed through the return channel by the fixed / rotating return frame, push roller, limit frame, and lifting plate. The discharging component serves two purposes (transporting return materials and removing finished products), with a clever structure and a high degree of automation.

[0020] Furthermore, a filter screen atop the hollow base effectively collects dust, debris, and waste liquid generated during processing, reducing environmental pollution, keeping the work area clean, and facilitating centralized processing. A cleaning roller automatically cleans the diverter drum sieve, preventing clogging, maintaining screening efficiency, and reducing downtime for maintenance. A squeeze rack helps push screened fine material into a recovery pipe, preventing accumulation in the diverter chamber.

[0021] The entire process, encompassing feeding, pre-cutting, lifting, screening, metal recovery, fine cutting / forming, and diversion / discharging, is compact and streamlined, enabling continuous, automated processing for the reuse of construction waste. Through multi-stage screening, metal recovery, waste material recycling, effective material briquetting, and waste chip collection, the device maximizes the utilization of the various components in the waste, achieving a truly "full utilization" strategy and providing an efficient and reliable solution for the reuse of construction waste.

[0032] In the first embodiment, the present invention provides a construction waste recycling device, such as Figure 1-Figure 3As shown, it includes a base 1, a conveying box 2, a feed piece 16, a whole material box 3, a diversion channel 4, a metal recovery cylinder 6, a return channel 7 and a discharge assembly 8. Two groups of bases 1 are set up, one on the left and one on the right; the conveying box 2 is located on one group of bases 1, feeding from the lower end and feeding upwards through the built-in feeding piece 10; the feed piece 16 is located on the feeding port of the conveying box 2, and performs preliminary cutting of the construction waste; the whole material box 3 is located on the other group of bases 1, with a pressing and cutting assembly 9 set on the top and a pushing assembly 11 set on the bottom; under the cooperation of the pressing and cutting assembly 9 and the pushing assembly 11, the construction waste is cut and moved again or shaped and moved; the diversion channel 4 is connected between the conveying box 2 and the whole material box 3, and the built-in diversion assembly 13 feeds through the conveying box 2 at one end, and after diverting the waste, the other end feeds the undiverted waste into the whole material box. Material box 3; one end of the metal recovery cylinder 6 is connected to the whole material box 3, and the other end is connected to the diversion channel 4 through the recovery pipe 5. The diverted waste is diverted from this path, and then enters the metal recovery cylinder 6 and the whole material box 3, and is finally formed into construction waste blocks; the return channel 7 is located below the diversion channel 4, connected between the conveying box 2 and the whole material box 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 formed construction waste blocks to enter; the discharge component 8 is set through the bottom of the return channel 7. On the one hand, it assists the horizontal movement of undiverted waste by rotation, and on the other hand, it moves the formed construction waste blocks out of the return channel 7 by lifting.

[0033] like Figure 4 As shown, the feed member 16 includes a feed hopper 17; the feed hopper 17 is connected to the feed port of the conveying box 2, and an electric cutting blade holder 14 for preliminary cutting is provided inside; the electric cutting blade holder 14 is opposite to the feed port.

[0034] It should be further explained that a feed gate is provided on the feed port.

[0035] Workers place construction waste into feed hopper 17. The electric cutting blade 14 rotates, cutting the waste with its blades and pushing it through the feed inlet and into conveyor box 2. The alignment of the electric cutting blade 14 with the feed inlet ensures forced cutting and pre-crushing of large pieces of construction waste, effectively preventing feed blockage. The tilted feed hopper 17, combined with the rotating blades, creates a directional thrust, significantly improving initial processing efficiency.

[0036] like Figure 3 As shown, the feeding member 10 is a spiral pushing frame, which transports the feed at 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 bulk material box 3 respectively, a connecting ring 403 connected to the connecting sleeve 402, and a connecting cylinder 401 connected between 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 arranged inside the outer ring frame 1304. The diversion cylinder 1302 is arranged within the inner ring frame 1305 and rotates synchronously with the inner ring frame 1305. The two ends of the diversion cylinder 1302 extend into the connecting sleeve 402 on the corresponding side and connect to the rotating sleeve 1301. A diversion cavity is left between the diversion cylinder 1302 and the connecting cylinder 401, which is connected to the recovery pipeline 5. The rotating sleeve 1301 rotatably connects to the connecting sleeve 402, one set of which is connected to the conveying box 2 and the other set of which is connected to the bulk material box 3.

[0038] It should be further explained that a vibrator is provided on the connecting tube 401; the diverter tube 1302 is tilted, with the high end connected to the conveying box 2 and the low end connected to the whole material box 3; by setting vibration and tilt screening, the screening is made more efficient.

[0039] The diverter drum 1302 has a feed port at one end and a discharge port at the other. As the waste material moves within the diverter drum 1302, it rotates and screens the material. Waste material that passes the diverter enters the diverter chamber and is separated from the waste material. Waste material that fails the diverter enters the bulk bin 3 for further cutting and processing.

[0040] It should be further explained that the outer ring frame 1304 divides the diversion cavity into independent diversion chambers; the diversion cylinder 1302 sets different diversion levels corresponding to different diversion chambers; the feed end of the recovery pipe 5 is connected to the diversion chamber one by one, and the discharge end is tilted downward, connected to the metal recovery cylinder 6 and a valve is set.

[0041] By setting multiple screening levels, small-sized waste can enter the corresponding recovery pipe 5 first, and large-sized waste can enter the corresponding recovery pipe 5 later. By setting the discharge time difference, waste materials of different size grades can enter the whole material box 3 respectively. Among them, the undiverted waste is returned to the conveying box 2 and the diversion channel 4 after secondary cutting, and screened again, and the diverted waste is removed after forming. The diversion cylinder 1302 is supported by a double-layer drive ring structure (outer ring frame 1304 + inner ring frame 1305) for multi-stage rotation screening, and the high-frequency vibration generated by the vibrator is used to make waste materials of different sizes roll in layers in the inclined channel, thereby improving the screening efficiency; the cleaning roller 1306 cleans the sieve holes in real time to avoid blockage, and the extrusion frame 1303 pushes the diverted waste to the recovery pipe 5 in a directional manner to reduce residue.

[0042] It should be further explained that a cleaning roller 1306 for cleaning the diverter cylinder 1302 is provided on the top of the outer ring frame 1304, and an extrusion frame 1303 for pressing down the diverted waste is provided on both sides.

[0043] It should be further explained that the cleaning roller 1306 rotates through the outer ring frame 1304 and cleans the sieve holes of the diverter cylinder 1302 through the bristles provided on the surface.

[0044] The extrusion frame 1303 rotates and penetrates the outer ring frame 1304. By setting extrusion plates on both sides, on the one hand, it seals the upper end of the diversion chamber, and on the other hand, it pushes the diverted waste to move toward the recovery pipe 5.

[0045] like Figure 6 As shown, the metal recovery drum 6 comprises a drum; one end of the drum is connected to the recovery pipe 5, and the other end is connected to the side wall of the bulk bin 3. A magnetic separation roller 12 and a pusher rack 15 are coaxially connected and located within the drum; the magnetic separation roller 12 is located on the side of the recovery pipe 5; and the pusher rack 15 is located on the side of the bulk bin 3. Before the waste enters the bulk bin 3, metal materials are magnetically intercepted to ensure efficient recycling. The coaxial linkage design of the magnetic separation roller 12 and the pusher rack 15 allows the metal-containing waste to continuously absorb iron impurities during the spiral propulsion of the metal-containing waste within the drum, achieving metal separation. The pusher rack 15 simultaneously pushes non-metallic waste into the bulk bin 3 to avoid secondary mixing and contamination.

[0046] like Figure 7 As shown, a mounting frame 301 is provided on the top of the material box 3; the pressing and cutting assembly 9 includes a lifting drive member 901 located on the mounting frame 301; the lifting end of the lifting drive member 901 extends into the material box 3 and is connected to the pressing and cutting plate 902; the pressing and cutting plate 902 is provided with a staggered hollow groove 1 903 and a hollow groove 2 910, and is also provided with a driving member 1 909 and a driving member 2 908. A lifting plate 1 905 and a lifting plate 2 904 are sequentially provided above the pressing and cutting plate 902 in parallel; the lifting plate 1 905 Driven by driving member 1 909, it moves up and down above the cutting plate 902 to control the cutting knife 1 906 at the bottom of the lifting plate 1 905 to enter and exit the hollow groove 1 903. The lifting plate 1 905 is provided with a hollow groove 3 911 corresponding to the hollow groove 2 910 one by one; the lifting plate 2 904 is driven by driving member 2 908 and moves up and down above the lifting plate 1 905 to control the cutting knife 2 907 at the bottom of the lifting plate 2 904 to enter and exit the hollow groove 3 911 and the hollow groove 1 903.

[0047] It should be further explained that the lifting drive member 901 is a cylinder, the cylinder body of which is located outside the whole material box 3 and is fixed by the mounting bracket 301, and the end of the telescopic rod is connected to the cutting plate 902; the driving member 1 909 and the driving member 2 908 are both a combination structure of a screw + motor, which drives the lifting plate 1 905 and the lifting plate 2 904 to rise and fall independently.

[0048] When cutting waste, the pressure plate 902 drives the lifting plate 1 905 and the lifting plate 2 904 to descend synchronously. Then, the cutting blades 1 906 and 2 907 alternately extend from the hollow slots 1 903 and 2 910 to cut the waste at the bottom. The hollow slots 1 903 / 2 910 of the pressure plate 902 and the cutting blades of the lifting plates 1 905 / 2 904 form an interlaced dynamic cutting network. The driving elements 1 909 / 2 908 independently control the raising and lowering of the blades, achieving precise cutting of the waste in both the vertical and horizontal directions, improving the uniformity of the crushing. During compaction, the cutting blades 1 906 and 2 907 retract, and the pressure plate 902 forms a complete compaction plane, pressing down on the waste to shape it and ensure the density of the waste block.

[0049] like Figure 3 As shown, the pusher assembly 11 includes a drive box and a pusher plate driven by the drive box to move horizontally; the pusher plate is opposite to the feed end of the return channel 7. By moving the pusher 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 an electric slide rail 805 located on the base 1 on both sides; the lifting plate 801 is driven by the electric slide rail 805 to rise and fall below the discharge port, and 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 on 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 pushing roller 806 is provided on the fixed return frame 802 and the rotating return frame 803 along the moving direction of the waste material; the auxiliary plane formed by the fixed return frame 802 and the rotating return frame 803 when they are 180 degrees coincides with the discharge port; when the fixed return frame 802 and the rotating return frame 803 are 90 degrees, the rotating return frame 803 and the limiting frame 804 form a square limiting structure.

[0051] After the undiverted waste is cut, it is pushed into the return channel 7 by the movement of the push plate. The waste moves with the push roller 806 through the return channel 7 and enters the conveying box 2 for re-screening. The diverted molded waste blocks are pushed into the return channel 7 by the movement of the push plate. The waste moves with the push roller 806 and falls on the fixed return frame 802. The rotating return frame 803 flips over and forms a square limiting structure with the limit frame 804. The lifting plate 801 moves down to remove the waste block. The fixed return frame 802 and the rotating return frame 803 are hingedly designed, and the angle switching is controlled by the electric slide rail 805. When it is horizontal at 180°, the push roller 806 assists in the recycling of waste. When it is flipped 90°, the limit frame 804 forms a rigid bracket, which cooperates with the lifting plate 801 to realize the lossless removal of the molded waste blocks. The dual-purpose machine reduces the complexity of the equipment.

[0052] like Figure 9As shown, the base 1 is hollow, and a recovery port connected to the conveying box 2 or the whole material box 3 is set on the top; a filter screen 101 is set on the recovery 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 by 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 are as follows:

[0054] S1. The staff puts the construction waste into the feed hopper 17. The electric cutting blade 14 rotates, and the blade cuts the construction waste, pushing it through the feed port and into the conveying box 2.

[0055] S2, the feeding piece 10 is used to transport the feed from the bottom to the top by rotating;

[0056] S3, the diverter drum 1302 has one end for feeding and the other end for discharging. During the movement of the waste in the diverter drum 1302, the diverter drum 1302 rotates and grades the waste. By setting multiple screening levels, the small-sized waste enters the corresponding recovery pipe 5 first, and the large-sized waste enters the corresponding recovery pipe 5 later. The undivided waste enters the bulk bin 3 first.

[0057] S4. The 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 that has not been diverted at the bottom;

[0058] S5. The cut waste is pushed into the return channel 7 by the movement of the push plate; the waste moves through the return channel 7 along with the push roller 806 and enters the conveying box 2 to enter the screening cycle again;

[0059] S6, the diverted waste is first intercepted by magnetic attraction to remove metal substances, and then enters the whole material box 3;

[0060] S7, the upper cutting blade 1 906 and the cutting blade 2 907 retract, and the bottom of the cutting plate 902 is pressed to form a pressing plane, pressing the waste material downward to shape it;

[0061] S8, the formed waste block is pushed into the return channel 7 by the movement of the push plate, and falls on the fixed return frame 802 as the push roller 806 moves. The rotating return frame 803 flips over and forms a square limiting structure with the limiting frame 804;

[0062] S9, the lifting plate 801 moves downward to remove the waste block;

[0063] S10, repeat the above steps for the secondary diverted and undiverted waste until all the waste is formed and removed;

[0064] S11. Waste liquid, powder, and debris from the waste treatment process enter the base 1, and the base 1 is cleaned after the treatment is completed.

[0065] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but 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.
