Description

Technical Field

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

[0002] With the acceleration of urbanization and the rapid development of the construction industry, the amount of construction waste generated is increasing. Construction waste mainly includes concrete blocks, bricks, wood, metal, plastic, etc. If these wastes are directly landfilled or piled up without treatment, they will not only occupy a large amount of land resources, but also pollute the environment. Therefore, construction waste can be recycled through sorting. Sorting of construction waste usually starts with primary screening to achieve preliminary sorting of materials. Traditional construction waste primary screening devices usually use simple screens or drum screens to classify the waste by size through mechanical vibration or rotation. However, wooden boards, plastic parts and aggregates of similar sizes cannot be separated, resulting in the need for additional manual sorting workers or more screening steps. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a construction waste sorting device.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] The sieve is a device for separating materials into smaller pieces and arranged in a downwardly inclined direction so as to guide the materials to flow toward the lower sieve assembly. The sieve assembly is provided with a screening drop-out port so that part of the materials fall from the screening drop-out port and the remaining materials are output from the end of the sieve assembly along the flow direction. The guide mechanism is arranged at intervals on the lower side of the material output side of the lower sieve assembly for receiving the heavy materials output from the end of the lower sieve assembly and at the same time blocking the light materials output from the end of the lower sieve assembly so that the light materials fall from the gap between the guide mechanism and the sieve assembly. The material-dipping anti-hanging device is arranged on the side of the guide mechanism facing the sieve channel for dipping the materials hanging on the end of the guide mechanism close to the sieve channel.

[0006] Furthermore, the flow guide mechanism includes a round rod and a flow guide plate, and the round rod is provided at the end of the flow guide plate facing the screening channel.

[0007] Furthermore, the material-moving and anti-hanging device includes a rotary drive mechanism installed on the frame, the output shaft of the rotary drive mechanism is connected to the material-moving shaft, and the material-moving rods are arranged on the peripheral wall of the material-moving shaft. The rotary drive mechanism is used to drive the material-moving rods to rotate, thereby moving the material hanging on the round rod off.

[0008] Furthermore, it also includes a scraper anti-winding mechanism installed on the frame, which is used to scrape off the material wound around the material diverter shaft.

[0009] Furthermore, the scraper anti-winding mechanism includes a mounting rod, which is mounted on the frame. A plurality of scraper rods are arranged on the mounting rod, and one end of the scraper rod facing away from the mounting rod is adjacent to the material diverting shaft.

[0010] Furthermore, the output shaft of the rotary drive mechanism is connected to the material-diverting shaft via a flexible member.

[0011] Furthermore, the output shaft of the rotary drive mechanism is provided with a first connecting plate, the first connecting plate is connected to a first pressure plate, the end of the material-discharging shaft is provided with a second connecting plate, the second connecting plate is connected to a second pressure plate, and the flexible part has two clamping parts, one of which is clamped and fixed by the first connecting plate and the first pressure plate, and the other clamping part is clamped and fixed by the second connecting plate and the second pressure plate.

[0012] Furthermore, the end of the scraper rod facing away from the mounting rod is provided with a scraper portion that is bent and tilted downward toward the material shifting axis.

[0013] Furthermore, the stepped frame includes two spaced side plates, the screening channel is formed between the two side plates, the screening material assembly is connected to the side plates, and the two side plates are connected and fixed by a connecting tube.

[0014] Furthermore, the step frame is elastically and movably mounted on the frame; a connecting shaft is provided on the outside of the step frame, a connecting frame is fixedly mounted on the connecting shaft, a mounting seat is provided below the corresponding connecting frame of the frame, and an elastic member is installed between the connecting frame and the mounting seat; the mounting seat is provided with a first positioning protrusion protruding upward, and a second positioning protrusion is provided at the bottom of the connecting frame, the lower end of the elastic member is sleeved with the first positioning protrusion, and the upper end is sleeved on the second positioning protrusion.

[0015] The present invention has the following beneficial effects:

[0016] The combination of a stepped frame and a vibrating drive mechanism enables efficient vibration sorting of construction waste within the screening channel. The vibrating drive mechanism provides stable vibration power, ensuring sufficient loosening of the waste within the screening channel, improving sorting efficiency. The screening components are arranged in a downward-sloping pattern, utilizing the waste's own gravity for sorting. Small particles fall through the screening dropout, achieving the first level of screening. The remaining material is discharged from the end of the screening component along the flow direction. Larger, denser, heavier materials (such as aggregates) are drawn into the diversion mechanism due to their greater forward inertial velocity, where they are received for the second level of screening. Larger, lighter materials (such as wood and plastic bags) are blocked by the diversion mechanism due to their lower forward inertial velocity, allowing them to fall through the gap between the diversion mechanism and the lowest screening component, achieving the third level of screening. The anti-hanging device is located on the side of the diversion mechanism facing the screening channel. It can promptly remove materials (mainly large plastic bags) that are stuck on the diversion mechanism, preventing material accumulation on the diversion mechanism and ensuring the continuity and stability of the sorting process. This reduces the phenomenon of material hanging and improves the accuracy and reliability of sorting.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] Please refer to Figure 1 and Figure 2 A construction waste sorting device in a preferred embodiment of the present invention includes a frame 100, a ladder frame 200, a screening material assembly 300, a guide mechanism 400 and a material anti-hanging device 500, which is used for preliminary coarse screening of construction waste.

[0040] The step frame 200 is movably mounted on the frame 100 . The step frame 200 forms a screening channel 210 . The upper end of the screening channel 210 is provided with a feed port 211 . A vibration drive mechanism 220 is mounted on the step frame 200 . The vibration drive mechanism 220 may specifically be a vibration motor.

[0041] The screening material assembly 300 is arranged in the screening channel 210 and arranged in an inclined downward direction to guide the material to flow toward the lowest screening material assembly 300, so as to utilize the garbage's own gravity for screening. The material output side of the lowest screening material assembly 300 can be considered as the material screening outlet 212. The screening material assembly 300 is provided with a screening drop-out port 311, so that part of the material falls from the screening drop-out port 311 and the remaining material is output from the end of the screening material assembly 300 along the flow direction; specifically, the screening material assembly 300 includes a plurality of screening material rods 310 arranged along the width direction of the screening channel 210. There are gaps between the screening material rods 310 to form a screening drop-out port 311, so that small materials can fall and be screened out.

[0042] The guide mechanism 400 is arranged at intervals below the material output side of the lowest screening component 300. The material output side of the lowest screening component 300 is that side of the lowest screening component 300 facing away from other screening components 300. For example, the screening components 300 are arranged in a direction inclined downward to the left. The lowest screening component 300 is that at the end of the arrangement direction, that is, the leftmost screening component 300. The material output side of the leftmost screening component 300 is that on the left side of the leftmost screening component 300. The guide mechanism 400 is arranged at intervals below the left side of the leftmost screening component 300.

[0043] A material discharge gap is formed between the guide mechanism 400 and the bottom screening component 300 for light materials to fall through. The guide mechanism 400 is used to receive the heavy materials output from the end of the bottom screening component 300 and guide this part of the materials along a preset direction. This part of the materials is heavy materials (aggregates) with larger size and higher density, and at the same time blocks the light materials output from the end of the bottom screening component 300, so that other materials fall through the gap between the guide mechanism 400 and the screening component 300. The other materials are light materials with larger size and lower density.

[0044] Specifically, as the vibration drive mechanism 220 vibrates, the material flows downward along the arrangement direction of the screening assembly 300, and in the process of flowing, the smaller materials in the material are screened out and fall into the first conveying mechanism 130 below from the screening drop port 311. In order to achieve material concentration and prevent the material from falling out of the first conveying mechanism 130, the width of the first conveying mechanism 130 can also be reduced, such as Figure 3 As shown, a collecting funnel 120 may be provided at the bottom of the ladder rack 200 .

[0045] Larger materials flow downward and are discharged from the material output side of the lowest screening assembly 300. Larger materials are generally coarse aggregates, large plastics, wood boards, etc. Coarse aggregates are heavy materials with high density, while plastics and wood boards are light materials with low density.

[0046] The material removal and anti-hanging device 500 is located on the side of the flow guide mechanism 400 facing the screening channel 210 and is used to remove material that is stuck on the end of the flow guide mechanism 400 near the screening channel 210. Generally, denser materials, due to their greater inertia, have a certain initial velocity when exiting the material sieve outlet 212. They are thrown a certain distance before falling into the flow guide mechanism 400 and being guided by the flow guide mechanism 400 to the second conveying mechanism 140. Large, lightweight materials with lower density, however, have a lower velocity when exiting the material sieve outlet 212 due to their lighter weight and lower inertia. Most of these materials will fall into the gap between the flow guide mechanism 400 and the lowest screening assembly 300, ultimately falling into the third conveying mechanism 150 below. Of course, some plastic may become stuck on the end of the flow guide mechanism 400 near the screening channel 210. This material needs to be handled by the material removal and anti-hanging device 500 to be redirected to the third conveying mechanism 150.

[0047] A preferred embodiment of the present invention provides a construction waste sorting device that achieves efficient vibration sorting of construction waste within a screening channel 210 through the combination of a stepped frame 200 and a vibration drive mechanism 220. The vibration drive mechanism 220 provides stable vibration power, ensuring that the waste is fully loosened within the screening channel 210, thereby improving sorting efficiency. The screening assemblies 300 are arranged in a downwardly inclined direction, utilizing the waste's own gravity for sorting. Some small-sized materials fall through the screening dropout 311, achieving the first level of screening. The remaining materials are discharged from the ends of the screening assemblies 300 along the flow direction. Larger and denser heavy materials (such as aggregates) enter the diversion mechanism due to their greater forward inertia and are received by the diversion mechanism, achieving the second level of screening. Larger, lighter materials (such as wood and plastic bags) are blocked by the diversion mechanism 400 due to their less forward inertia, causing them to fall through the gap between the diversion mechanism and the lowest screening assembly, achieving the third level of screening. The material removal and anti-hanging device 500 is located on the side of the diversion mechanism 400 facing the screening channel. It can promptly remove material (primarily large plastic bags) that is stuck on the diversion mechanism 400, preventing material accumulation on the diversion mechanism 400 and ensuring the continuity and stability of the sorting process. This reduces the phenomenon of material hanging and improves the accuracy and reliability of sorting. Existing technology typically only implements two levels of screening, causing large aggregates and large pieces of plastic to flow downstream together, requiring a large number of personnel to sort downstream. The concept of the present invention is to use the inertia of falling materials to further separate a portion of the large pieces of plastic. Of course, some plastic will still flow into the diversion mechanism 400 along with the heavy materials (large aggregates), but the present invention can at least reduce the amount of lightweight material mixed with the heavy materials, thereby reducing the majority of lightweight materials flowing downstream and reducing the number and workload of downstream sorting personnel.

[0048] Reference Figure 4 and Figure 5 In some embodiments of the present invention, the guide mechanism 400 includes a round rod 410 and a guide plate 420. The round rod 410 is arranged at the end of the guide plate 420 facing the screening channel 210. The round rod 410 can reduce the impact damage of the material and reduce the resistance caused to the material, effectively reducing the material hanging. In addition, even if a plastic bag is hung on it, it can be easily and smoothly removed by the material anti-hanging device 500 due to the structure of the round rod 410.

[0049] Reference Figure 4 and Figure 6In a further embodiment of the present invention, the material-preventing device 500 includes a rotary drive mechanism 510 mounted on the frame 100. The output shaft of the rotary drive mechanism 510 is connected to a material-preventing shaft 520. Material-preventing rods 521 are arranged around the circumference of the material-preventing shaft 520. The rotary drive mechanism 510 is used to drive the material-preventing rods 521 to rotate, thereby removing material hanging on the round rod 410. The rotary drive mechanism 510 drives the material-preventing rods 521 to rotate, which can promptly remove material hanging on the round rod 410, thereby reducing the amount of material hanging on the round rod 410. In addition, continuous rotation can promptly process material hanging on the round rod 410. In order to limit the hanging material, an arc-shaped baffle 411 is connected to the bottom of the round rod 410 near the material-preventing shaft 520, so that the material will not be thrown out by the material-preventing rod 521 and cannot accurately fall onto the third conveying mechanism 150.

[0050] The plastic bag that falls directly or the plastic bag that is pushed off from the round rod by the material pusher 521 will be entangled on the material pusher shaft 520. Over time, the material pusher shaft 520 is prone to be entangled with more materials, thereby affecting the rotation and normal operation of the material pusher shaft 520, requiring frequent maintenance and cleaning. Figure 2 and Figure 4 In a further embodiment of the present invention, a scraper and anti-winding mechanism 600 is further included, which is mounted on the frame 100 and is used to scrape off material wrapped around the feed shaft 520. The scraper and anti-winding mechanism 600 can scrape off material wrapped around the feed shaft 520, reducing material accumulation on the feed shaft 520, further improving the continuity and stability of sorting, and reducing the frequency of maintenance and cleaning.

[0051] Reference Figure 8The scraper anti-winding mechanism 600 includes a mounting rod 610, which is mounted on the frame 100. A plurality of scraper rods 611 are arranged on the mounting rod 610. The end of the scraper rod 611 facing away from the mounting rod 610 is adjacent to the material-diverting shaft 520, so that when the material-diverting shaft 520 rotates, the end of the scraper rod 611 adjacent to the material-diverting shaft 520 can scrape off the material wound on the material-diverting shaft 520 to prevent the material from accumulating and winding around the material-diverting shaft 520. Usually, as soon as the plastic bag is rewound on the material-diverting shaft 520, it will be scraped off by the scraper rod 611. The plastic bag has not been wrapped around the material-diverting shaft 520 for many turns, so that the plastic bag has not been tightly wrapped around the material-diverting shaft 520 at this time and can be easily scraped off by the scraper rod 611. The resistance is not large, and the normal rotation of the material-diverting shaft 520 is not affected. It can be understood that the connection position between the material stripping rod 521 and the material stripping shaft 520 is most likely to be entangled with materials such as plastic bags. For this reason, there are usually two scraper rods 611 on both sides of each material stripping rod 521, and the material stripping rod 521 will pass through the gap between the two scraper rods 611, that is, multiple groups of scraper rods 611 will be provided, and there will be two scraper rods 611 in the same group. The number of groups of scraper rods 611 will be greater than or equal to the number of material stripping rods 521, that is, it is ensured that the material stripping rod 521 will correspond to a group of scraper rods 611, so that the group of scraper rods 611 will be adjacent to the two sides of the corresponding material stripping rod 521, and the root position where the material stripping rod 521 is connected to the material stripping shaft 520 will be scraped and cleaned in a targeted manner.

[0052] Reference Figure 6 and Figure 7 In some embodiments of the present invention, the output shaft of the rotary drive mechanism 510 is connected to the material tapping shaft 520 via a flexible member 530. The deformability of the flexible member 530 not only improves the flexibility of the connection, but also reduces the impact force of the material transmitted from the material tapping shaft 520 to the rotary drive mechanism 510 through its cushioning effect, thereby reducing the impact and damage to the rotary drive mechanism 510 and improving the stability and reliability of the device. The flexible member 530 is arranged in a circular arrangement to achieve multi-position connection, thereby improving the stability of the connection and torque transmission.

[0053] Reference Figure 7The first and second clamping plates 523 are connected to each other to form a plurality of springs, and the springs 531 are connected to the first and second clamping plates 523 to form a plurality of springs. After the tightening portion 531 is rotated and subjected to force, both ends will be subjected to force, and only one end will not be subjected to force, resulting in the end being detached or damaged by stress concentration. Therefore, the two ends will not easily detach from the first connecting plate 511 and the first pressing plate 512, the second connecting plate 522, and the second pressing plate 523. If the flexible member 530 is not annular, the two clamping portions 531 are only connected to one end by a connecting portion 532, so that one end of the two clamping portions 531 is disconnected. When the force is large, only one end of the clamping portion 531 is subjected to tension, which can easily be pulled out or broken. If the force is applied at both ends, stress concentration on one end can be avoided, and the flexible member 530 can also be avoided from being pulled out, thereby increasing the life of the flexible member 530. In addition, the flexible member 530 is annular, and even if it moves due to pulling, it moves along its own annular contour, which does not affect its operation. The flexible member 530 can be made of elastic metal material, canvas, rubber tape, etc.

[0054] Reference Figure 8 In some embodiments of the present invention, a scraper portion 612 is provided at one end of the scraper rod 611 facing away from the mounting rod 610, and is bent and tilted downward toward the material diverting shaft 520. The scraper portion 612 is provided at one end of the scraper rod 611 facing away from the mounting rod 610, and is bent and tilted downward toward the material diverting shaft 520. The downward bend and tilt of the scraper portion 612 prevents the scraped material from moving along the scraper rod 611 toward the mounting rod 610. Instead, the scraped material remains between the scraper portion 612 and the material diverting shaft 520, and is subsequently carried away by the rotating diverting rod 521, and is then carried into the third conveying mechanism 150 below.

[0055] Reference Figure 1 and Figure 3In some embodiments of the present invention, the stepped frame 200 includes two spaced-apart side panels 230. The screening channel 210 is formed between the two side panels 230. The screening assembly 300 is connected to the side panels 230. The two side panels 230 are fixedly connected by a connecting tube 231. The fixing effect of the connecting tube 231 improves the stability of the stepped frame 200. It is understood that the tops of the two side panels 230 are connected together by a connecting bracket, which is away from the feed port 211.

[0056] Reference Figure 2 and Figure 9 In some embodiments of the present invention, the ladder frame 200 is elastically mounted on the frame 100; a connecting shaft 240 is provided on the outside of the ladder frame 200, and a connecting frame 250 is fixedly mounted on the connecting shaft 240. The upper end of the connecting frame 250 is connected to the cover plate 252 to clamp the connecting shaft 240. The connecting frame 250 and the cover plate 252 are provided with corresponding holes to be connected and fixed by fasteners. A mounting seat 110 is provided below the corresponding connecting frame 250 of the frame 100, and an elastic member 260 is installed between the connecting frame 250 and the mounting seat 110, thereby realizing the elastic activity of the ladder frame 200, so that when vibrating, the ladder frame 200 can vibrate elastically, better transmit the vibration to the material, and reduce the vibration transmitted to the frame 100, thereby reducing the impact of the vibration on the components installed on the frame 100, and making the components installed on the frame 100 easy to loosen. The mounting base 110 is provided with an upwardly projecting first positioning protrusion 111, and the bottom of the connecting frame 250 is provided with a second positioning protrusion 251. The lower end of the elastic member 260 is sleeved with the first positioning protrusion 111, and the upper end is sleeved with the second positioning protrusion 251. The first positioning protrusion 111 and the second positioning protrusion 251 are used to limit the ends of the elastic member 260, allowing the elastic member 260 to be stably installed. The elastic member 260 can be a component with elastic deformation capabilities, such as a rubber tube or a compression spring. It is understood that the connecting shaft 240 can be provided on the outer side of the side plate 230, and each side plate 230 can be provided with multiple connecting shafts 240 to achieve multi-position elastic support and improve support stability. Multiple elastic members can be provided between each connecting frame 250 and the mounting base 110 to achieve sufficient elastic support.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
