Description

Technical Field

[0001] This invention relates to the field of construction waste treatment technology, and in particular to a sorting device and method for construction waste. Background Technology

[0002] Construction waste is a type of construction debris. Construction debris refers to slag, soil, waste materials, silt, and other waste generated by construction units or individuals during the construction, laying, demolition, or repair of various buildings, structures, pipelines, etc.

[0003] Construction waste refers to building debris generated during construction projects due to human or natural causes, including slag, excavated soil, silt, and other waste materials. These materials offer no benefit to the building itself, but they are substances generated during the construction process and require appropriate treatment to achieve the desired project completion. Because it is a holistic process, consideration of each stage is crucial.

[0004] Most existing construction waste needs to be crushed for subsequent processing. However, during crushing, some of the construction waste contains mesh-like materials (such as construction safety nets), which can easily become entangled on the surface of the crushing equipment, affecting its normal operation or even causing damage. Summary of the Invention

[0005] This invention discloses a classification device and method for construction waste, aiming to solve the technical problem that in the prior art, most construction waste needs to be crushed during processing to facilitate subsequent treatment. However, during crushing, some of the construction waste contains mesh-like materials (such as construction safety nets), which easily become entangled on the surface of the crushing device, affecting the normal use of the device or even causing damage to the equipment.

[0006] This invention proposes a classification device for construction waste, comprising a support base, with a water separation chamber fixedly connected to the inner walls of both sides of the support base, and a crushing chamber fixedly connected to the top of the water separation chamber. An anti-winding component is installed inside the crushing chamber, and filtration and dust suppression components are installed inside both the crushing chamber and the water separation chamber. Rectangular openings are provided on both outer walls of the water separation chamber, and a lead screw and a limiting rod are installed inside the water separation chamber. A separation motor is fixedly connected to one outer wall of the water separation chamber, and the output shaft of the separation motor is connected to one end of the lead screw via a coupling. A common separation scraper is installed on the outer walls of the lead screw and the limiting rod. A collection and separation component is installed at the bottom of the water separation chamber, and the collection and separation component is located inside the support base.

[0007] Equipped with a separation motor, lead screw, limit rod, separation scraper, anti-winding component, filtration and dust suppression component, and collection and separation component, the device separates lower-quality waste materials (such as wood or plastic) from construction waste for classification. The separation motor, lead screw, and separation scraper simultaneously adsorb and separate ferrous waste materials, further classifying the construction waste. The filtration and dust suppression component reduces dust generated during crushing, preventing dust from escaping and causing environmental pollution or inhalation, thus meeting the requirements for safe operation and environmental cleanliness. The anti-winding component cuts through the mesh-like structures inside the construction waste, preventing them from entangled with the crushing rollers and affecting the device's operation, thus meeting the device's crushing requirements.

[0008] In a preferred embodiment, the anti-winding assembly includes drive shafts, both ends of which are movably connected to the inner walls of both sides of the crushing chamber. Crushing rollers are fixedly connected to the outer walls of both drive shafts. Four movable openings are equidistantly provided on one side of the outer walls of both crushing rollers. Two circular ring frames are movably connected to the outer walls of both drive shafts. Multiple elastic plates are equidistantly provided on the outer walls of the four circular ring frames. The inner walls of every two elastic plates are fixedly connected to the same movable rod. The multiple movable rods are located inside the multiple movable openings. Multiple annular openings are equidistantly provided on the outer walls of the two crushing rollers. Rubber retaining rings are fixedly connected to the inner walls of both sides of the multiple annular openings. Multiple blades are equidistantly fixed to the outer walls of the multiple movable rods. The multiple blades are located inside the multiple annular openings. Inside, and on the outside of each of the two drive shafts, there are two mounting housings. One side of the outer wall of each of the four mounting housings is fixedly connected to the inner walls of both sides of the crushing chamber. One side of the outer wall of each of the four mounting housings is connected to one side of the outer wall of each of the four ring frames, and multiple through holes are opened. The outer walls of each of the four mounting housings are provided with mounting openings. Rotary motors are fixedly connected to the inner walls of each of the four mounting openings. The output shafts of the four rotary motors are connected to pushers through couplings. The four pushers are located inside the four mounting housings. One side of the inner wall of each of the four mounting housings is fixedly connected to a return spring. One end of each of the two return springs on the same side is fixedly connected to the same connecting plate. Four locking rods are fixedly connected to the outer walls of the opposite sides of the two connecting plates. The eight locking rods are located inside the eight through holes.

[0009] By incorporating an anti-winding component, the device prevents mesh-like materials in the construction waste from entangled in the crushing rollers during crushing, thus avoiding disruption to normal operation or even equipment damage. This enhances the device's effectiveness. Furthermore, the anti-winding component operates intermittently, preventing the blades from prolonged contact with the waste material and causing damage, thereby extending the device's lifespan. Additionally, a rubber retaining ring prevents the retracted blades from entering the circular opening and getting stuck, further improving the device's practicality.

[0010] In a preferred embodiment, a drive motor is fixedly connected to one side of the outer wall of the crushing chamber. The output shaft of the drive motor and one end of the two drive shafts are each provided with a transmission wheel. A steering wheel is movably connected to one side of the outer wall of the crushing chamber. The outer walls of the two transmission wheels and the steering wheel are provided with the same transmission belt, and the outer walls of the transmission belt are in contact with the outer walls of the transmission wheels.

[0011] In a preferred embodiment, the dust suppression filtration assembly includes two conveying pumps, each fixedly connected to one outer wall of the water separation chamber. The input ends of both pumps are connected to a water supply chamber via pipes, and the output ends of both pumps are fixedly connected to conveying pipes. The output ends of both conveying pipes are fixedly connected to dust suppression fittings. Filter frames are fixedly connected to one outer wall of each of the two water supply chambers. Mounting rods are movably connected to one outer wall of each of the two filter frames. One end of each mounting rod is fixedly connected to a winding reel. Connecting wires are fixedly connected to the inner walls of each winding reel. One end of each connecting wire is fixedly connected to the outer walls of both sides of the separation scraper. Cleaning brushes are fixedly connected to one outer wall of each winding reel. Torsion springs are fitted onto the outer walls of both mounting rods. One end of each torsion spring is fixedly connected to one outer wall of each of the two filter frames, and the other end of each torsion spring is fixedly connected to one outer wall of each of the two winding reels.

[0012] By incorporating a dust suppression filter, the dust suppression filter can effectively reduce dust during the crushing of construction waste, preventing large amounts of dust generated during crushing from being inhaled by workers, thereby increasing the safety of the device and reducing dust pollution to the working environment. Simultaneously, during dust suppression, the filter can also filter the water entering the conveying pump, preventing debris in the water from clogging the equipment. Furthermore, the device ensures the filtration effect of the filter frame during use.

[0013] In a preferred embodiment, the collection and separation assembly includes a collection chamber, a water separation chamber with an insertion interface at its bottom, the outer wall of the collection chamber contacting the inner wall of the insertion interface, a power motor fixedly connected to the bottom of the collection chamber, the output shaft of the power motor connected to a gear one via a coupling, a gear two movably connected to the bottom of the inner wall of the collection chamber, four stirring rods fixedly connected to the top of the gear two, and the gear two meshing with the gear one; a gear ring is provided at the bottom of the inner wall of the collection chamber, the gear ring meshing with the gear one, multiple power sockets are provided at equal intervals on the top of the gear ring, each power socket having an electromagnet on its top, and a limit frame is fixedly connected to the bottom of the inner wall of the collection chamber, the inner wall of the limit frame contacting the outer wall of the gear ring.

[0014] By incorporating a collection and separation component, the device can collect waste materials that have already undergone low-quality separation, facilitating their collection and processing by staff. Simultaneously, the component further separates the waste materials, adsorbing and separating iron-containing waste. This allows the device to classify and separate construction waste, facilitating subsequent processing and increasing its effectiveness. Furthermore, during the adsorption of iron-containing waste, the device can agitate the waste entering the collection chamber to enhance its contact with the electromagnet, thereby improving separation efficiency.

[0015] A method for using a construction waste sorting device, comprising the following steps:

[0016] Step 1: Start the drive motor. The drive motor drives the transmission wheel to rotate, which in turn causes the transmission belt and steering wheel to run. This causes the transmission wheel to drive the two drive shafts to rotate, which in turn causes the two crushing rollers to rotate to crush the construction waste.

[0017] Step 2: While crushing, the rotating motor starts and drives the pusher to rotate, causing the pusher to intermittently push the connecting plate to move to the opposite side, and drive the locking rod to engage with the through hole. At this time, the ring frame is locked and fixed, the crushing roller continues to run, and the deformation of the elastic plate causes the movable rod to move inside the movable opening, and drives the blade to unfold to the outside of the crushing roller to cut the mesh.

[0018] Step 3: During use, the crushed construction waste falls into the water separation chamber. At this time, the separation motor is started, which drives the lead screw to rotate, thereby moving the separation scraper to separate the construction waste with lower quality floating on the water surface. At the same time, the separation scraper can pull the connecting line, which causes the winding reel to drive the cleaning brush to rotate and clean the filter frame. The conveying pump is started to deliver water to the dust suppression pipe for crushing and dust suppression.

[0019] Step 4: After the lower-quality construction waste is separated, it enters the collection bin. The power motor and power base are started. The power motor drives gear one to rotate, which in turn drives gear two, the stirring rod and the gear ring to rotate. At the same time, the power base drives the electromagnet to attract the iron inside the waste. Finally, the staff classifies and collects the waste.

[0020] As can be seen from the above, the construction waste sorting device provided by the present invention has the effect of preventing the mesh from getting tangled. When in use, the device can intermittently cut the mesh on the crushing roller through the movable rod and the blade, thereby avoiding the mesh from getting tangled and affecting the normal use of the device or even causing damage to the equipment.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] The present invention discloses a sorting device for construction waste, which is mainly used in scenarios where the mesh-like materials in construction waste are easy to entangle in the crushing device, affecting the use of the device.

[0032] Reference Figure 1-8 A sorting device for construction waste includes a support base 1. A water separation chamber 3 is fixedly connected to the inner walls of both sides of the support base 1. A crushing chamber 4 is fixedly connected to the top of the water separation chamber 3. An anti-winding component 5 is installed inside the crushing chamber 4. A dust-reducing filter 6 is installed inside both the crushing chamber 4 and the water separation chamber 3. Rectangular openings are provided on both outer walls of the water separation chamber 3. A lead screw 12 and a limiting rod 14 are installed inside the water separation chamber 3. A separation motor 11 is fixedly connected to one outer wall of the water separation chamber 3. The output shaft of the separation motor 11 is connected to one end of the lead screw 12 via a coupling. A separation scraper 13 is installed on the outer walls of the lead screw 12 and the limiting rod 14. A collection and separation component 2 is installed at the bottom of the water separation chamber 3 and is located inside the support base 1.

[0033] Specifically, during use, the separation motor 11, lead screw 12, and separation scraper 13 can separate low-quality waste materials (such as wood or plastic) from construction waste for classification. At the same time, the collection and separation component 2 can adsorb and separate iron waste materials from the waste materials for further classification. The dust filtering component 6 can reduce the dust generated during crushing, thereby preventing dust from escaping and causing environmental pollution or being inhaled by people, thus meeting the requirements for safe use of the device and environmental cleanliness. The anti-entanglement component 5 can cut off the mesh inside the construction waste during use, preventing the mesh from entangled with the crushing roller 501 during crushing and affecting the operation of the device, thus meeting the crushing requirements of the device.

[0034] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 In a preferred embodiment, the anti-winding component 5 includes drive shafts 507. Both ends of the two drive shafts 507 are connected to the inner walls of both sides of the crushing chamber 4 via bearings. Crushing rollers 501 are fixedly connected to the outer walls of both drive shafts 507. Four movable openings 502 are equidistantly provided on one side of the outer wall of each of the two crushing rollers 501. Two circular ring frames 509 are connected to the outer walls of both drive shafts 507 via bearings. Multiple elastic plates 508 are equidistantly provided on the outer walls of the four circular ring frames 509. The same movable rod 505 is fixedly connected to the inner wall of every two elastic plates 508. The multiple movable rods 505 are located inside the multiple movable openings 502. Multiple annular openings are equidistantly provided on the outer walls of both crushing rollers 501. Rubber retaining rings 504 are fixedly connected to the inner walls of both sides of the multiple annular openings. Multiple blades 506 are equidistantly fixed to the outer walls of the multiple movable rods 505. The multiple blades 506 are located in the multiple annular openings. Inside the four mounting housings 503, two mounting shells 503 are provided on the outside of the two drive shafts 507. The outer wall of one side of the four mounting shells 503 is fixedly connected to the inner walls of both sides of the crushing chamber 4. The outer wall of one side of the four mounting shells 503 is provided with multiple through holes 510 connected to the outer wall of one side of the four ring frames 509. The outer wall of each of the four mounting shells 503 is provided with a mounting opening. The inner wall of each of the four mounting openings is fixedly connected to a rotating motor 514. The output shaft of each of the four rotating motors 514 is connected to a pusher 515 through a coupling. The four pushers 515 are located inside the four mounting shells 503. The inner wall of one side of each of the four mounting shells 503 is fixedly connected to a return spring 513. One end of each of the two return springs 513 on the same side is fixedly connected to the same connecting plate 511. The outer wall of each of the two connecting plates 511 is fixedly connected to four locking rods 512. The eight locking rods 512 are located inside the eight through holes 510.

[0035] Specifically, during crushing, the rotating motor 514 starts, driving the pushing component 515 to rotate. During rotation, the pushing component 515 intermittently contacts the connecting plate 511. Upon contact, the pushing component 515 pushes the connecting plate 511, causing the two connecting plates 511 to move towards opposite sides. This, in turn, causes the locking rod 512 to pass through the through hole 510 on the mounting housing 503 and engage with the through hole 510 on the ring frame 509. At this time, the locking rod 512 can fix the ring frame 509. As the drive shaft 507 and the crushing roller 501 continue to rotate and crush, the movable rod 505 can move inside the movable opening 502 along with the rotation of the crushing roller 501. At the same time, the elastic plate 508 on the ring frame 509 deforms. At this time, the movable rod 505 moves with the movable opening 502 and drives the blade 506 to unfold outward from the ring opening and to the outside of the rubber retaining ring 504, thereby contacting the mesh wrapped on the crushing roller 501 and cutting it. After the cutting is completed, the pusher 515 separates from the connecting plate 511, and the return spring 513 drives the connecting plate 511 to reset, so that the through hole 510 of the snap rod 512 separates, so that the ring frame 509 rotates with the drive shaft 507. At this time, the elastic plate 508 returns to its original state and drives the movable rod 505 to reset, so that the blade 506 retracts into the rubber retaining ring 504.

[0036] In specific application scenarios, the anti-winding component 5 is suitable for the crushing of construction waste. That is, when crushing construction waste, the anti-winding component 5 can prevent the mesh-like objects in the waste from entangled in the crushing roller 501, thereby avoiding affecting the normal use of the device or even causing damage to the equipment, thus increasing the effectiveness of the device. Moreover, the anti-winding component 5 operates intermittently during use, preventing the blade 506 from being in a cutting state for a long time and coming into contact with the waste and being damaged, thereby increasing the service life of the device. At the same time, the rubber retaining ring 504 can block and protect the retracted blade 506 during use, preventing the waste from entering the inner ring and getting stuck, thus increasing the practicality of the device.

[0037] Reference Figure 1 , Figure 3 and Figure 4 In a preferred embodiment, a drive motor 8 is fixedly connected to one side of the outer wall of the crushing chamber 4. The output shaft of the drive motor 8 and one end of the two drive shafts 507 are provided with transmission wheels 7. A steering wheel 10 is connected to one side of the outer wall of the crushing chamber 4 through a bearing. The outer walls of the two transmission wheels 7 and the steering wheel 10 are provided with the same transmission belt 9. The outer wall of the transmission belt 9 is in contact with the outer wall of the transmission wheel 7.

[0038] Specifically, during use, the drive motor 8 starts, drives one of the transmission wheels 7 to rotate, and through the transmission wheel 7 and the steering wheel 10, it drives the transmission belt 9 to run. At the same time, the transmission belt 9 can drive the other transmission wheel 7 to rotate, so that the two transmission wheels 7 drive the two drive shafts 507 to rotate in opposite directions, thereby driving the crushing roller 501 to rotate to crush construction waste.

[0039] Reference Figure 2 , Figure 6 and Figure 7 In a preferred embodiment, the dust suppression filter assembly 6 includes two conveying pumps 601, both fixedly connected to one outer wall of the water separation chamber 3. The input ends of both pumps 601 are connected to a water supply chamber 602 via pipes, and the output ends of both pumps 601 are fixedly connected to conveying pipes 604. The output ends of both conveying pipes 604 are fixedly connected to dust suppression pipe fittings 603. Filter frames 605 are fixedly connected to one outer wall of each of the two water supply chambers 602, and mounting rods 609 are connected to one outer wall of each of the two filter frames 605 via bearings. Each mounting rod 609 has a winding reel 607 fixedly connected to one end. The inner walls of the two winding reels 607 are fixedly connected to connecting wires 608. One end of each connecting wire 608 is fixedly connected to the outer walls of the two sides of the separating scraper 13. A cleaning brush 606 is fixedly connected to one side of the outer wall of each winding reel 607. A torsion spring 610 is fitted on the outer wall of each mounting rod 609. One end of each torsion spring 610 is fixedly connected to one side of the outer wall of each of the two filter frames 605. The other end of each torsion spring 610 is fixedly connected to one side of the outer wall of each of the two winding reels 607.

[0040] Specifically, during use, the delivery pump 601 is started, which draws water from inside the water separation chamber 3 into the water supply chamber 602 and delivers it to the dust suppression rod through the delivery pipe 604. The water is then sprayed out through the dust suppression pipe 603 to suppress dust. As the separation scraper 13 moves, it pulls the connecting line 608, causing the connecting line 608 to rotate the winding reel 607, which in turn rotates the cleaning brush 606. The cleaning brush 606 cleans the filter frame 605 on the water supply chamber 602. At the same time, on the other side of the separation scraper 13, the connecting line 608 is relaxed, and the torsion spring 610 can drive the winding reel 607 to reset and rotate, thereby driving the cleaning brush 606 to clean and prevent the filter frame 605 from becoming clogged.

[0041] In specific application scenarios, the dust suppression filter 6 is suitable for the crushing and separation of low-quality waste materials. That is, the dust suppression filter 6 can perform dust suppression when construction waste is crushed, preventing a large amount of dust generated during crushing from being inhaled by workers, thereby increasing the safety of the device and reducing the pollution of the working environment caused by dust. At the same time, when performing dust suppression, the dust suppression filter 6 can filter the water entering the conveying pump 601 to prevent impurities in the water from clogging the equipment. Meanwhile, the device can ensure the filtration effect of the filter frame 605 during use.

[0042] Reference Figure 1 , Figure 2 and Figure 8 In a preferred embodiment, the collection and separation component 2 includes a collection chamber 201, a water separation chamber 3 with an insertion interface at the bottom, the outer wall of the collection chamber 201 in contact with the inner wall of the insertion interface, a power motor 203 fixedly connected to the bottom of the collection chamber 201, the output shaft of the power motor 203 connected to a gear 204 via a coupling, a gear 209 rotatably connected to the bottom of the inner wall of the collection chamber 201, four stirring rods 206 fixedly connected to the top of the gear 209, and the gear 209 meshing with the gear 204; a gear ring 202 is provided at the bottom of the inner wall of the collection chamber 201, the gear ring 202 meshing with the gear 204, a plurality of power supply seats 205 are provided at equal intervals on the top of the gear ring 202, each of the power supply seats 205 is provided with an electromagnet 207, and a limit frame 208 is fixedly connected to the bottom of the inner wall of the collection chamber 201, the inner wall of the limit frame 208 in contact with the outer wall of the gear ring 202.

[0043] Specifically, construction waste enters the collection bin 201. At this time, the power motor 203 is started, which drives gear 204 to rotate. Since gear 204 meshes with gear 209 and gear ring 202, the power motor 203 can drive gear 209 and gear ring 202 to rotate. In turn, gear 209 drives the stirring rod 206 to rotate, stirring the waste inside the collection bin 201. At the same time, the power base 205 is started, which makes the electromagnet 207 run. The gear ring 202 drives the power base 205 and electromagnet 207 to rotate in the opposite direction to the stirring rod 206 to increase the stirring effect. The electromagnet 207 adsorbs and separates the ferrous waste. Finally, the staff removes the collection bin 201 to classify and collect the waste and ferrous waste.

[0044] In specific application scenarios, the collection and separation component 2 is suitable for the separation of iron waste from construction waste. That is, the collection and separation component 2 can collect the waste after the low-quality waste has been separated, so that the workers can collect and process it. At the same time, the collection and separation component 2 can separate the waste again, separating and adsorbing the iron waste contained in the waste. This allows the device to classify and separate construction waste, which is convenient for subsequent processing and increases the effectiveness of the device. In addition, when adsorbing iron waste, the device can stir the waste entering the collection bin 201 to increase its contact with the electromagnet 207 and improve the separation efficiency.

[0045] A method for using a construction waste sorting device, comprising the following steps:

[0046] Step 1: The drive motor 8 starts and drives one of the transmission wheels 7 to rotate. The transmission wheel 7 and the steering wheel 10 assist in driving the transmission belt 9 to run. At the same time, the transmission belt 9 can drive the other transmission wheel 7 to rotate, so that the two transmission wheels 7 drive the two drive shafts 507 to rotate in opposite directions, thereby driving the crushing roller 501 to rotate to crush the construction waste.

[0047] Step 2: Simultaneously with crushing, the rotating motor 514 starts, driving the pusher 515 to rotate. During rotation, the pusher 515 intermittently contacts the connecting plate 511. Upon contact, the pusher 515 pushes the connecting plate 511, causing the two connecting plates 511 to move towards opposite sides. This, in turn, causes the locking rod 512 to pass through the through hole 510 on the mounting housing 503 and engage with the through hole 510 on the ring frame 509. At this time, the locking rod 512 can fix the ring frame 509. As the drive shaft 507 and the crushing roller 501 continue to rotate and crush, the movable rod 505 can move inside the movable opening 502 along with the rotation of the crushing roller 501. When the elastic plate 508 on the ring frame 509 deforms, the movable rod 505 moves with the movable opening 502 and drives the blade 506 to unfold outward from the ring opening and to the outside of the rubber retaining ring 504, thereby contacting and cutting the mesh wrapped on the crushing roller 501. After the cutting is completed, the pusher 515 separates from the connecting plate 511, and the return spring 513 drives the connecting plate 511 to reset, so that the locking rod 512 separates from the through hole 510, and the ring frame 509 rotates with the drive shaft 507. At this time, the elastic plate 508 returns to its original state, drives the movable rod 505 to reset, and causes the blade 506 to retract into the rubber retaining ring 504.

[0048] Step 3: During use, the crushed construction waste falls into the water separation chamber 3. At this time, the separation motor 11 is started, which drives the lead screw 12 to rotate, thereby causing the separation scraper 13 to move and separate the construction waste with lower quality floating on the water surface. At the same time, the conveying pump 601 is started, which can draw water from the water separation chamber 3 into the water supply chamber 602 and deliver it to the dust suppression rod through the conveying pipe 604. Then, it is sprayed out through the dust suppression pipe 603 to suppress dust. At this time, as the separation scraper 13 moves, the separation scraper 13 can pull the connecting line 608, which drives the winding reel 607 to rotate, thereby driving the cleaning brush 606 to rotate. At this time, the cleaning brush 606 can clean the filter frame 605 on the water supply chamber 602. Meanwhile, on the other side of the separation scraper 13, the connecting line 608 is relaxed, and the torsion spring 610 can drive the winding reel 607 to reset and rotate, thereby driving the cleaning brush 606 to clean and prevent the filter frame 605 from clogging.

[0049] Step 4: After the lower-quality construction waste is separated, it enters the collection bin 201. At this time, the power motor 203 is started, which drives gear 204 to rotate. Since gear 204 meshes with gear 209 and gear ring 202, the power motor 203 can drive gear 209 and gear ring 202 to rotate. In turn, gear 209 drives the stirring rod 206 to rotate, stirring the waste inside the collection bin 201. At the same time, the power base 205 is started, which makes the electromagnet 207 run. The gear ring 202 drives the power base 205 and electromagnet 207 to rotate in the opposite direction to the stirring rod 206, so that the electromagnet 207 adsorbs and separates the ferrous waste. Finally, the staff removes the collection bin 201 to classify and collect the waste and ferrous waste.
