Description

Technical Field

[0001] This invention relates to the field of waste sorting equipment technology, and in particular to a system for separating aged waste. Background Technology

[0002] Aged waste is a mixture formed from household waste after long-term landfilling. It typically contains lightweight aggregates such as plastic bags, rags, and sawdust, as well as medium-weight aggregates such as stones and bricks. These materials vary significantly in particle size, mass, and morphology. To achieve subsequent resource utilization or harmless treatment, aged waste usually needs to be screened and separated. Currently, equipment such as roller screens, drum screens, or vibrating screens are commonly used to sort aged waste, classifying materials of different particle sizes.

[0003] However, due to the strong entanglement properties of flexible materials such as plastic bags and cloth strips in aged waste, existing screening equipment easily separates large aggregates, but medium and light aggregates often stick together, making separation difficult and prone to material entanglement on the screen shaft, accumulation and blockage of screen holes or screening areas. This reduces material agitation and screening efficiency, and affects the continuous and stable operation of the equipment, sometimes even requiring shutdown for cleaning, thus lowering the equipment's working efficiency and reliability. Therefore, how to improve the agitation of aged waste during transportation, reduce material entanglement, and achieve continuous and stable separation of different materials has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a system for separating aged waste.

[0005] The technical solution adopted by this invention to solve its technical problem is: This invention provides a system for separating aged waste, including a base, on which a chain drive mechanism and a drive assembly for driving the chain drive mechanism are mounted. The chain drive mechanism includes a chain, on which a plurality of first rollers and a plurality of second rollers are spaced apart, the first rollers and second rollers being alternately arranged along the direction of chain movement. The base is provided with a reverse constraint structure, which applies rotational constraints in opposite directions to the first rollers and second rollers respectively, causing the first rollers and second rollers to rotate in opposite directions under the action of the reverse constraint structure. A separation gap for screening is formed between adjacent first rollers and second rollers. Under the action of the drive assembly and the reverse constraint structure, the chain drive mechanism drives the first rollers and second rollers to change their posture along a preset conveying direction, thereby separating different materials.

[0006] Preferably, the first roller and the second roller are rotatably arranged relative to the chain, and the ends of the first roller and the second roller in the length direction are respectively provided with a first gear and a second gear; the reverse constraint structure includes a first toothed plate and a second toothed plate fixedly mounted on the base. The first toothed plate is used to mesh with the first gear of the first roller, and the second toothed plate is used to mesh with the second gear of the second roller. The first toothed plate and the second toothed plate respectively apply meshing constraints in opposite directions to the first roller and the second roller, so that under the drive of the chain, the first roller and the second roller generate rotational motion in opposite directions. This structure allows the first roller and the second roller to not only perform translational conveying during the movement with the chain, but also to be subjected to meshing constraints in opposite directions by the first toothed plate and the second toothed plate respectively, thereby forming a stable reverse rotation state, so that the material is continuously moved and turned during the conveying process, avoiding slippage in a single conveying state, increasing the degree of disturbance of the material in the separation area, making the screening process more thorough, and reducing entrainment and accumulation.

[0007] Preferably, a rod is also fixed on the roller body. The rod is located at the end of the roller body along its length, and the central axis of the rod coincides with the central axis of the corresponding roller body. The chain has a mounting position, and the roller body is rotatably mounted on the mounting position via the rod. By setting a rod coaxial with the roller body and cooperating with the mounting position on the chain, the roller body can be stably rotated and connected to the chain. This structure ensures the free rotation of the roller body while improving the overall assembly stability, making it less prone to swaying or jamming during continuous operation, thereby enhancing the reliability of the chain conveyor mechanism under complex material conditions.

[0008] Preferably, the first gear and the second gear are respectively mounted on the first roller and the second roller via corresponding rods. The distance between the first gear and the first roller is not equal to the distance between the second gear and the second roller. By differentiating the distances between the first gear and the first roller and between the second gear and the second roller, and by coordinating the staggered arrangement of the first and second gear plates, interference is avoided between the two sets of rollers during meshing constraint, making the control of the roller rotation direction more reliable.

[0009] Preferably, the base is further provided with two first plates, which are respectively located at both ends of the base in the width direction to limit external materials. A second plate is provided on the side of the two first plates that are close to each other. The Shore hardness of the second plate is greater than that of the first plate. The second plate is used to withstand the impact of external materials to protect the first plate. The two first plates are used to form the material boundary in the width direction. Since the second plate has higher hardness, it bears the main impact contact surface in actual operation, so that the direct impact of external materials is preferentially applied to the second plate, thereby reducing the force frequency and damage risk of the first plate, and thus improving the durability of lateral protection, making the boundary structure less prone to failure during long-term operation of the equipment.

[0010] Preferably, the base also includes two frames located at both ends of the base's width. One end of each frame, furthest from the base, bends and extends towards the other frame, forming an inverted L-shape. A first plate is fixed to the bent end of the frame furthest from the base. By setting the frame in an inverted L-shape and arranging the first plate at the bent end, a spatially separated force path is created between the lateral protection structure and the main body of the equipment. This arrangement concentrates material impacts on the outer support area rather than directly transmitting them to the main structure of the base, thereby improving the overall impact resistance distribution and enhancing the overall structural rigidity.

[0011] Preferably, the first toothed plate is located at the bent end of the frame away from the base, and the second toothed plate is located at the end of the frame close to the base. The first toothed plate and the second toothed plate are parallel and not coplanar, and the distance between the first gear and the first roller is smaller than the distance between the second gear and the second roller. The first toothed plate and the second toothed plate are respectively arranged in different height areas of the frame and form a staggered meshing relationship with the first gear and the second gear. At the same time, with different gear spacing settings, the two rollers on both sides form asymmetrical meshing conditions during the constraint process. This design avoids the overlap of meshing conflict areas, makes the reverse rotation process smoother, reduces the probability of tooth surface interference, and improves long-term operating stability.

[0012] Preferably, a shock-absorbing component is provided between the first plate and the frame. This component reduces the impact transmitted from the first plate to the frame. Arranged between the first plate and the frame, the shock-absorbing component absorbs and buffers energy when material impacts are transmitted to the lateral protection structure, preventing the impact load from directly acting on the rigid frame. This structure reduces the localized impact concentration effect, slows down the rate of structural fatigue accumulation, thereby extending the overall service life of the lateral protection component and reducing the impact on the toothed plate.

[0013] Preferably, the base is also equipped with a load-bearing roller, which is located on the moving path of the chain to support the chain, thereby reducing the sagging deformation of the chain under load. The load-bearing roller is located below the running path of the chain to provide intermittent or continuous support to the chain, which can share the material load borne by the chain, improve the chain's load-bearing capacity, and ensure that the chain drive mechanism can stably transport large amounts of aged waste.

[0014] A separation method for a system for separating aged waste includes the following steps: S1. The material to be separated is conveyed to the chain drive mechanism; S2. The drive assembly drives the chain transmission mechanism to move along the preset conveying direction. Under the action of the reverse constraint structure, the first roller and the second roller generate rotational motion in opposite directions. S3. The material to be separated is conveyed by the chain drive mechanism and screened at the separation gap formed by the first roller and the second roller. S4. Materials of different particle sizes pass through or remain in the separation gap to achieve separation. In actual operation, this method continuously conveys materials into the separation area via a chain structure. Under the disturbance of the roller's reverse rotation, the particles are constantly tumbled and redistributed, causing materials of different particle sizes to naturally classify at the separation gap. Medium-sized materials cannot pass through the gap and continue to move in the conveying direction, while smaller particles pass through the gap under the action of disturbance and gravity to complete screening. This achieves a continuous dynamic separation process, avoiding the clogging and accumulation problems that easily occur in static screening.

[0015] The beneficial effects of this invention are as follows: by setting a chain transmission mechanism, a drive component, and a reverse constraint structure on the base, the chain drives the first roller and the second roller to move along the preset conveying direction while generating rotational motion in opposite directions. The separation gap formed between adjacent first and second rollers is used to screen the material, thereby promoting the turning, breaking up, and screening of aged waste, realizing continuous separation of materials of different particle sizes, improving screening efficiency and separation effect, reducing the probability of material blockage, entanglement, and accumulation, and ensuring continuous and stable operation of the equipment.

[0027] The following is a brief introduction to some relevant content, terms, or nouns involved in this application. Example 1

[0028] Reference Figures 1 to 5 A system for separating aged waste includes a base 1, on which a chain drive mechanism 2 and a drive assembly 3 for driving the chain drive mechanism are mounted. The chain drive mechanism 2 includes a chain 20, on which a plurality of first rollers 21 and a plurality of second rollers 22 are spaced apart, and the first rollers 21 and second rollers 22 are alternately arranged along the movement direction of the chain 20. The base 1 is provided with a reverse constraint structure 4, which is used to apply rotational constraints in opposite directions to the first rollers 21 and second rollers 22 respectively, and the first rollers 21 and second rollers 22 generate rotational motions in opposite directions under the action of the reverse constraint structure 4. A separation gap 200 for screening is formed between adjacent first rollers 21 and second rollers 22. Under the action of the drive assembly 3 and the reverse constraint structure 4, the chain drive mechanism 2 drives the first rollers 21 and second rollers 22 to change their posture along a preset conveying direction, so as to separate different materials.

[0029] With the above-described structural configuration, during use, the chain transmission mechanism 2, drive assembly 3, and reverse constraint structure 4 are installed on the base 1, causing the chain 20 to drive the first roller 21 and the second roller 22 to move along the preset conveying direction while simultaneously generating rotational motions in opposite directions. The separation gap 200 formed between the adjacent first roller 21 and second roller 22 is used to screen the material, thereby promoting the turning, breaking up, and screening of aged waste, achieving continuous separation of materials of different particle sizes, improving screening efficiency and separation effect, reducing the probability of material blockage, entanglement, and accumulation, and ensuring the continuous and stable operation of the equipment.

[0030] The materials referred to in this technical solution are light aggregates and medium aggregates in aged waste. Light aggregates include plastic bags, cloth strips, etc., and medium aggregates include stones, etc. The aged waste separation system also includes at least a screen conveyor that works in conjunction with the base 1. The screen conveyor is used to transport the separated light aggregates.

[0031] The separation gap 200 is naturally formed by the alternating arrangement of adjacent first rollers 21 and second rollers 22 on the chain 20, and the size of the gap is defined by the outer diameter of the adjacent rollers, the installation spacing and the pitch of the chain 20.

[0032] During the operation of the chain drive mechanism 2, the separation gap 200 moves synchronously with the chain 20, and its geometric dimensions remain relatively stable, thus forming a continuously moving screening channel.

[0033] Under the counter-rotation of the first roller 21 and the second roller 22, the material is continuously disturbed and its contact posture is changed above the gap 200, so that the light aggregate with a particle size smaller than the gap size passes through the gap 200 and is separated under the action of gravity and friction, while the medium aggregate with a larger particle size is continuously conveyed to the discharge end.

[0034] Specifically, the first roller 21 and the second roller 22 are rotatably arranged relative to the chain 20. A first gear 210 and a second gear 220 are respectively provided at the ends of the first roller 21 and the second roller 22 along their length. The reverse constraint structure 4 includes a first toothed plate 41 and a second toothed plate 42 fixedly mounted on the base 1. The first toothed plate 41 meshes with the first gear 210 of the first roller 21, and the second toothed plate 42 meshes with the second gear 220 of the second roller 22. The first toothed plate 41 and the second toothed plate 42 apply opposite directions of meshing to the first roller 21 and the second roller 22, respectively. The combined constraint causes the first roller 21 and the second roller 22 to rotate in opposite directions under the drive of the chain 20. This structure allows the first roller 21 and the second roller 22 to not only translate and convey during the movement with the chain 20, but also to be subjected to meshing constraints in opposite directions by the first toothed plate 41 and the second toothed plate 42, thereby forming a stable reverse rotation state. This ensures that the material is continuously moved and turned during the conveying process, avoiding slippage in a single conveying state, increasing the degree of disturbance of the material in the separation area, making the screening process more thorough, and reducing entrainment and accumulation.

[0035] In this technical solution, the first toothed plate 41 and the second toothed plate 42 refer to rigid plates with teeth that cooperate with gears. The gears referred to in this technical solution are the general term for the first gear 210 and the second gear 220. The first gear 210 and the second gear 220 can be spur gears or bevel gears. Similarly, the roller body is the general term for the first roller body 21 and the second roller body 22. For example, the roller body refers to the first roller body 21 and the second roller body 22.

[0036] A partition plate is provided between the chain 20 and the lightweight aggregate feeding space.

[0037] In order to enable the first roller 21 and the second roller 22 to stably form opposite rotational motions during synchronous movement with the chain 20, in this embodiment, the first gear 210 and the second gear 220 respectively form intermittent or continuous meshing relationships with the first tooth plate 41 and the second tooth plate 42 fixedly disposed on the base 1.

[0038] When the chain 20 moves along the preset conveying direction under the action of the drive assembly 3, the first roller 21 and the second roller 22 located on the working surface move in translational motion with the chain 20, and at the same time, their end gears respectively engage in relative rolling meshing with the corresponding tooth plates.

[0039] Since the first toothed plate 41 and the second toothed plate 42 are located on both sides of the chain 20 and are subjected to opposite tangential constraint forces, the first gear 210 and the second gear 220 are subjected to opposite tangential friction torques during meshing, thereby driving the first roller 21 and the second roller 22 to generate opposite rotational motions. This reverse rotation state is maintained intermittently or continuously during the continuous conveying process of the chain 20, so that the material is continuously moved, turned over and redistributed on the conveying path.

[0040] To achieve a continuous meshing relationship, the first toothed plate 41 and the second toothed plate 42 can be configured as an annular structure on the seat 1.

[0041] Specifically, a rod 23 is fixedly installed on the roller body. The rod 23 is located at the end of the roller body along its length, and the central axis of the rod 23 coincides with the central axis of the corresponding roller body. The chain 20 is provided with a mounting position, and the roller body is rotatably mounted on the mounting position via the rod 23. By setting the rod 23 coaxial with the roller body and cooperating with the mounting position on the chain 20, the roller body can be stably rotated and connected to the chain 20. This structure ensures the free rotation of the roller body while improving the overall assembly stability, making it less likely for the roller body to wobble or jam during continuous operation, thereby enhancing the reliability of the chain conveyor mechanism under complex material conditions.

[0042] In addition to enabling the rotational connection between the roller and the chain 20, the rod 23 is also used to construct the coaxial support reference of the roller, so that the roller can rotate around the stable axis when subjected to material impact load.

[0043] Meanwhile, a clearance fit structure is formed between the rod 23 and the chain 20 mounting position, which enables the roller to have a certain micro displacement compensation capability during rotation, thereby absorbing the impact load caused by uneven material distribution and avoiding roller jamming or eccentric wear.

[0044] The rod 23 passes through the mounting position, which can help prevent garbage from contaminating the gears.

[0045] Specifically, the first gear 210 and the second gear 220 are respectively mounted on the first roller 21 and the second roller 22 via corresponding rods 23. The distance between the first gear 210 and the first roller 21 is not equal to the distance between the second gear 220 and the second roller 22. The first toothed plate 41 and the second toothed plate 42 are respectively located below the first gear 210 and above the second gear 220. By differentiating the distances between the first gear 210 and the first roller 21 and between the second gear 220 and the second roller 22, and by staggering the first toothed plate 41 and the second toothed plate 42, interference is avoided between the two sets of rollers during meshing constraint, that is, the possibility of interference between the corresponding meshing areas of the first gear 210 and the second gear 220 is avoided, making the control of the roller rotation direction more reliable.

[0046] The rod 23 corresponding to the first gear 210 and the second gear 220 can be configured with different structural strengths (such as diameter) according to different lengths to meet different torque transmission requirements.

[0047] Preferably, the first toothed plate 41 and the second toothed plate 42 are respectively disposed above the first gear 210 and below the second gear 220.

[0048] To avoid motion interference between the first gear 210 and the second gear 220 during spatial arrangement and meshing, this embodiment differentiates the radial installation distance between the first gear 210 and the first roller 21 and the radial installation distance between the second gear 220 and the second roller 22, so that the two sets of gears form a staggered distribution structure in the axial and radial directions.

[0049] Meanwhile, the first toothed plate 41 and the second toothed plate 42 are staggered vertically along the height direction on the seat body 1, so that the two sets of meshing pairs are in different meshing planes, thereby avoiding the intersection and overlap of meshing trajectories.

[0050] Through the above spatial decoupling design, the first roller 21 and the second roller 22 each form an independent meshing constraint path during operation, avoiding the risk of tooth surface collision and jamming, and improving the stability of long-term continuous operation.

[0051] Specifically, the base 1 is also provided with two first plates 11, which are respectively located at both ends of the width direction of the base 1 to limit external materials. A second plate 12 is provided on the side of the two first plates 11 that are close to each other. The Shore hardness of the second plate 12 is greater than that of the first plate 11. The second plate 12 is used to withstand the impact of external materials to protect the first plate 11. The two first plates 11 are used to form the material boundary in the width direction. Since the second plate 12 has higher hardness, it bears the main impact contact surface in actual operation, so that the direct impact of external materials is preferentially applied to the second plate 12, thereby reducing the force frequency and damage risk of the first plate 11, and thus improving the durability of lateral protection, making the boundary structure less prone to failure during long-term operation of the equipment.

[0052] Specifically, the base 1 is also provided with two frames 10, which are located at both ends of the width direction of the base 1. The end of the frame 10 away from the base 1 bends and extends toward the other frame 10 to form an inverted L-shape. The first plate 11 is fixedly installed at the bent end of the frame 10 away from the base 1. By setting the frame 10 as an inverted L-shape and arranging the first plate 11 at the bent end, the lateral protection structure and the main body of the equipment form a spatially separated force path, which reduces the possibility of the impact force acting directly on the base 1. This arrangement makes the material impact more concentrated on the outer support area, rather than directly transmitted to the main structure of the base 1, thereby improving the overall impact resistance distribution and enhancing the overall structural rigidity.

[0053] Specifically, the first toothed plate 41 is located at the bent end of the frame 10 away from the base 1, and the second toothed plate 42 is located at the end of the frame 10 close to the base 1. The first toothed plate 41 and the second toothed plate 42 are parallel and not coplanar. The distance between the first gear 210 and the first roller 21 is smaller than the distance between the second gear 220 and the second roller 22. The first toothed plate 41 and the second toothed plate 42 are respectively arranged in different height areas of the frame 10, and form a staggered meshing relationship with the first gear 210 and the second gear 220. At the same time, with different gear spacing settings, the two rollers on both sides form a staggered meshing relationship during the constraint process. This design avoids the overlap of meshing conflict areas, makes the reverse rotation process smoother, reduces the probability of tooth surface interference, and improves long-term operating stability.

[0054] The first toothed plate 41 and the second toothed plate 42 are preferably straight toothed plates, and the first gear 210 and the second gear 220 are preferably straight gears. For example, the first toothed plate 41 and the second toothed plate 42 can also be helical toothed plates, and correspondingly, the first gear 210 and the second gear 220 are selected as helical gears.

[0055] Specifically, a shock-absorbing component is provided between the first plate 11 and the frame 10. This component reduces the impact transmitted from the first plate 11 to the frame 10. Arranged between the first plate 11 and the frame 10, the shock-absorbing component absorbs and buffers energy when material impacts are transmitted to the lateral protection structure, preventing the impact load from directly acting on the rigid frame 10. This structure reduces the localized impact concentration effect, slows down the rate of structural fatigue accumulation, thereby extending the overall service life of the lateral protection component, and simultaneously reduces the transmission of impact loads to the frame 10 and the first toothed plate 41.

[0056] The elastic buffer unit can be any one or a combination of rubber damping blocks, polyurethane elastomers, spring damping structures or gas spring structures, used to generate elastic deformation in the compression direction to absorb and attenuate the impact force and vibration energy generated by the operation of the chain drive mechanism.

[0057] Specifically, the base 1 is also equipped with a load-bearing roller 5, which is located on the moving path of the chain 20 to support the chain 20, thereby reducing the sagging deformation of the chain 20 under load. The load-bearing roller 5 is located below the running path of the chain 20 to provide intermittent or continuous support to the chain 20, which can share the material load borne by the chain 20, improve the load-bearing capacity of the chain 20, and ensure that the chain drive mechanism 2 can stably transport large weights of aged waste.

[0058] The load-bearing roller 5 is positioned below the chain 20 to form a support contact surface, which is used to provide reverse support force when the chain 20 carries materials, thereby reducing the deflection deformation of the chain 20 when the span is large.

[0059] By applying segmented support to the chain 20 through the load-bearing roller 5, the stress state of the chain 20 is changed from cantilever stress to multi-point support stress structure, which improves the overall running stability of the chain 20 and reduces the load fluctuation of the drive component 3.

[0060] A separation method for a system for separating aged waste includes the following steps: S1. The material to be separated is conveyed to the chain drive mechanism 2; S2. The drive assembly 3 drives the chain transmission mechanism 2 to move along the preset conveying direction. Under the action of the reverse constraint structure 4, the first roller 21 and the second roller 22 generate rotational motion in opposite directions. S3. The material to be separated is conveyed by the chain drive mechanism 2 and screened at the separation gap 200 formed by the first roller 21 and the second roller 22. S4. Materials of different particle sizes pass through or remain in the separation gap 200 to achieve separation of different materials. In actual operation, the material is continuously conveyed into the separation area by the chain structure. Under the disturbance of the reverse rotation of the roller, it is constantly turned over and the particle state is redistributed, so that materials of different particle sizes form a natural grading behavior at the separation gap 200. Medium aggregate cannot pass through the gap and continues to move with the conveying direction, while light aggregate passes through the gap under the action of disturbance and gravity to complete the screening. This achieves a continuous dynamic separation process and avoids the clogging and accumulation problems that are easy to occur in static screening. Example 2

[0061] Embodiment 2 of this application can be implemented alone or in combination with Embodiment 1 described above, and this application does not impose any restrictions.

[0062] A system for separating aged waste includes a base 1; the base 1 is provided with a first roller 21 and a second roller 22, and a separation gap 200 is formed between the first roller 21 and the second roller 22, the separation gap 200 being used for the flow of lightweight aggregate. The base 1 is provided with a drive assembly 3, which drives the first roller 21 and the second roller 22 to rotate toward one side of the separation gap 200 so that materials with a particle size smaller than the width of the separation gap 200 can pass through the separation gap 200. The first roller 21 and the second roller 22 are at different heights at their two ends in the axial direction. That is, the first roller 21 and the second roller 22 are inclined on the seat 1 so that materials with a particle size larger than the width of the separation gap 200 are discharged along the inclined direction of the first roller 21 and the second roller 22, while light aggregates can be discharged through the separation gap 200.

[0063] In this embodiment, the chain drive mechanism 2 and the reverse constraint structure 4 in Embodiment 1 are omitted. The drive component 3 directly drives the first roller 21 and the second roller 22 to rotate, and can achieve a similar effect. Of course, this embodiment can be applied to Embodiment 1.
