Description

Technical Field

[0001] This invention relates to the field of resource recycling technology, specifically to an organic solid waste recycling device. Background Technology

[0002] Against the backdrop of increasingly urgent demands for resource recycling and environmental protection, the efficient treatment and resource recovery of organic solid waste has become one of the core research directions in the industry. Organic solid waste, as a type of waste with wide sources and complex composition, includes agricultural straw, livestock and poultry manure, kitchen waste, and organic residues generated in industrial production. If it is not treated scientifically and rationally, it will not only occupy a large amount of land resources, but may also produce harmful gases and leachate due to decomposition, causing serious pollution to the soil, water bodies, and atmospheric environment. Therefore, achieving the reduction, harmlessness, and resource recovery of organic solid waste is of great significance for promoting the development of a circular economy and alleviating environmental pressure. In existing technologies, a common approach to the resource-based treatment of organic solid waste is to process it into solid particles with a certain particle size. These solid particles can be used as biomass fuel, organic fertilizer raw materials, etc., to achieve secondary utilization and thus realize the goal of resource recycling.

[0003] Specifically, the existing processing flow typically involves three core steps: First, the organic solid waste to be treated is fed into a crusher to break it into finely crushed material with relatively uniform particle size; second, the crushed material is discharged from the crusher and transferred to another independent drying device to remove excess moisture from the material; finally, the dried material is taken out again from the drying device and transferred to an extrusion molding device to compress the material into solid particles with a fixed shape and a certain particle size, thus completing the resource-based processing of organic solid waste. However, the existing processing procedures described above have several technical drawbacks that cannot be ignored in practical applications. First, the entire processing relies on the coordinated operation of multiple independent pieces of equipment, such as crushers, drying equipment, and extrusion molding equipment. Each piece of equipment requires a certain amount of space, and material transfer channels and operating spaces must be reserved between the equipment, resulting in a significant increase in the footprint of the entire processing system. This is especially true in urban peripheries or industrial parks where land resources are scarce, where equipment layout is difficult and construction costs rise sharply. Second, during the multiple transfers of materials, due to factors such as the sealing limitations of the transfer devices, the inherent scattering characteristics of the materials, and the gaps between the inlet and outlet of the equipment, some materials may scatter, remain, or be lost due to airborne contamination. This loss rate is even higher for finer-grained crushed materials, which not only leads to a decrease in the resource utilization rate of organic solid waste but may also cause secondary environmental pollution due to scattered materials, increasing subsequent cleanup costs. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide an organic solid waste recycling device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an organic solid waste resource recycling device, comprising an outer cylinder and a base frame, wherein an inner cylinder mechanism is coaxially arranged inside the outer cylinder, and the inner cylinder mechanism includes a fixed cylinder; An extrusion molding mechanism is fixed to the bottom of the outer cylinder, and the fixed cylinder, the outer cylinder and the extrusion molding mechanism enclose an extrusion molding cavity. The fixed cylinder is coaxially provided with a rotating mechanism, and the rotating mechanism includes a rotating cylinder. The rotating cylinder and the fixed cylinder enclose each other to form a lifting and drying chamber. The outer wall of the rotating cylinder is fixed with a spiral blade located inside the lifting and drying chamber. The inner cylinder mechanism also includes a permeable plate laid at the bottom of the fixed cylinder, a support frame fixed to the top of the permeable plate, and multiple sets of mounting plates evenly fixed to the top edge of the fixed cylinder. The permeable plate is used to filter excess water in the material, and the mounting plate is used to fix the fixed cylinder and the outer cylinder relative to each other. The top of the outer cylinder has multiple sets of mounting grooves that cooperate with the mounting plate. The rotating drum has a crushing drum fixed inside, and two sets of crushing rollers are installed inside the crushing drum. The bottom of the rotating drum has a discharge port, which connects the inside of the crushing drum with the lifting and drying chamber, so that the material crushed by the crushing rollers falls into the lifting and drying chamber. The rotating mechanism also includes a connector and a transmission rod. A drive motor is installed inside the base frame. The output end of the drive motor is fixedly connected to the bottom end of the transmission rod to provide rotational power to the transmission rod. The plug-in frame is fixedly connected to the bottom of the inside of the rotating cylinder, and the rotating cylinder is plugged into the support frame of the inner cylinder mechanism through the plug-in frame to achieve relative positioning between the rotating cylinder and the fixed cylinder. One end of the transmission rod is fixedly connected to the bottom of the plug-in frame, and the other end passes through the permeable plate of the inner cylinder mechanism vertically and extends to the bottom of the fixed cylinder. The rotating mechanism also includes a bevel gear and a spur gear transmission module. The spur gear transmission module is installed on both sides of the crushing roller, and the end of the spur gear transmission module away from the crushing roller is connected to a bevel gear. The top of the outer cylinder is covered with a connecting top cover, and a fixed gear ring is fixed at the bottom of the connecting top cover. The bevel gear meshes with the fixed gear ring. When the transmission rod drives the rotating cylinder to rotate, the bevel gear revolves with the rotating cylinder and meshes with the fixed gear ring to achieve rotation. Then, it drives the crushing roller to rotate through the spur gear transmission module. Multiple sets of drying plates are fixed to the inner wall of the outer cylinder. The inner side of the drying plates extends into the lifting drying chamber. After being crushed, the material enters the lifting drying chamber through the discharge port. It is captured by the spiral blades and lifted by the rotation of the spiral blades. During the lifting process, the drying plates blow drying gas toward the material to complete the drying. The material that is spirally lifted to the top of the lifting drying chamber falls along the top edge of the fixed cylinder into the extrusion molding chamber, where the extrusion molding mechanism completes the extrusion molding operation. A fixed annular tube is fitted on the outer side of the outer cylinder. The fixed annular tube is connected to the drying plate one by one through multiple sets of connecting pipes. An input pipe for receiving external drying gas is also connected to the fixed annular tube. The drying plate has multiple sets of air holes connected to the lifting and drying chamber on its inner side. The drying gas is transported to the drying plate through the input pipe, the fixed annular pipe, and the connecting pipe, and is blown onto the material in the lifting process through the air holes. The extrusion molding mechanism includes a fixed frame fixed to the bottom of the outer cylinder, a forming ring plate installed at the bottom of the fixed frame, multiple sets of extrusion rollers movably installed above the forming ring plate, and a drive ring sleeved on the outside of the multiple sets of extrusion rollers. The surface of the forming ring plate is uniformly provided with forming holes, and the driving ring is used to drive multiple sets of extrusion rollers to revolve so as to extrude the material through the forming holes to complete the forming. A planetary speed-increasing gear module is sleeved on the outside of the transmission rod. The planetary speed-increasing gear module includes a sun gear fixedly connected to the bottom of the outer cylinder, a planet carrier fixedly connected to the transmission rod, multiple sets of planet gears movably mounted on the planet carrier, and a gear ring carrier fixedly connected to the drive ring of the extrusion molding mechanism. The planetary gears mesh with the sun gear and the gear carrier respectively, and are used to amplify the rotational speed transmitted from the transmission rod to the drive ring; The base frame is fixed to the bottom of the fixed frame, and a material discharge rack located below the forming ring plate is fixed to the outside of the base frame.

[0006] In summary, the present invention has the following main beneficial effects: 1. This invention integrates the three core functions of crushing, drying, and extrusion molding into an integrated structure consisting of an outer cylinder, an inner cylinder mechanism, a rotating mechanism, and an extrusion molding mechanism. The fixed cylinder and the outer cylinder form a lifting drying chamber, and the fixed cylinder and the extrusion molding mechanism form an extrusion molding chamber. With the crushing cylinder inside the rotating cylinder, there is no need to set up transfer channels and operating gaps between multiple devices, which significantly reduces the overall footprint of the equipment and reduces the site construction and equipment installation costs. It is especially suitable for urban peripheries or industrial parks where land resources are scarce. 2. This invention utilizes a closed internal operating process. Organic solid waste is fed into the crushing cylinder from above, crushed by the crushing rollers, and then falls into the lifting and drying chamber through the discharge port. After being lifted by the spiral blades and dried by the drying plate, it falls into the extrusion molding chamber for molding. The entire process requires no external transfer. This design completely avoids the material loss caused by insufficient sealing of the transfer device and the scattered nature of the material in the prior art. At the same time, it eliminates secondary environmental pollution caused by scattered materials. It not only improves the resource utilization rate of organic solid waste, but also reduces subsequent cleaning costs, meeting the requirements of efficient and environmentally friendly resource recycling.

[0009] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0010] The embodiments of the present invention will now be described.

[0011] Example like Figure 1-13 As shown, the core of the organic solid waste recycling equipment in this embodiment lies in integrating three major functions: "crushing-drying-extrusion molding". Integrated operation is achieved through the precise assembly of each component. The specific assembly process and component connection relationships are as follows: Assembly of basic support components: The outer cylinder 1 is processed. The outer cylinder 1 is made of metal sheet and is in the shape of a vertical cylinder. At the same time, the base frame 15 is processed. The base frame 15 is a frame structure used to support the overall weight of the equipment. The bottom of the base frame 15 has a reserved mounting groove 16 to facilitate the fixing of the equipment in a designated site.

[0012] The base frame 15 houses the drive motor, with its output end facing upwards. The drive motor is fixedly connected to the bottom end of the transmission rod 407 via a coupling, ensuring that the drive motor can drive the transmission rod 407 to rotate synchronously after starting.

[0013] Inner cylinder mechanism 2 is assembled with outer cylinder 1: The inner cylinder mechanism 2 includes a fixed cylinder 201, a permeable plate 202, a support frame 203, and a mounting plate 204. The permeable plate 202 is laid and fixed at the bottom of the fixed cylinder 201. The permeable plate 202 is used to filter excess water in the material. The support frame 203 is fixed at the bottom inside the fixed cylinder 201.

[0014] Multiple sets of mounting plates 204 are fixed to the top edge of the fixed cylinder 201. A mounting groove 16 adapted to the mounting plate 204 is opened at the corresponding position on the top of the outer cylinder 1. The mounting plate 204 is fixed to the outer cylinder 1 by bolts, so as to realize the detachable connection between the fixed cylinder 201 and the outer cylinder 1, which facilitates subsequent equipment maintenance.

[0015] Installation of rotating mechanism 4: The rotating mechanism 4 includes a rotating cylinder 401, a connector 406, and a transmission rod 407. A spiral blade 5 is fixed to the outer wall of the rotating cylinder 401. The spiral blade 5 is spiral-shaped and located entirely inside the lifting and drying chamber 6. The connector 406 is fixed to the bottom of the rotating cylinder 401, and its center is fixedly connected to the transmission rod 407, ensuring that the transmission rod 407 can drive the rotating cylinder 401 to rotate synchronously when it rotates.

[0016] The transmission rod 407 penetrates the permeable plate 202 vertically. A sealing component is installed at the penetration position between the transmission rod 407 and the permeable plate 202 to ensure that the transmission rod 407 can rotate flexibly and to prevent material moisture from leaking out from the penetration point.

[0017] Assembly of crushed components: Inside the rotating drum 401, a crushing drum 402 is coaxially fixed. The crushing drum 402 is used to contain the organic solid waste to be crushed. A discharge port 405 is opened at the bottom of the rotating drum 401. The top of the crushing drum 402 is used for feeding. The discharge port 405 connects the inside of the crushing drum 402 with the lifting and drying chamber 6, so that the crushed material can fall into the lifting and drying chamber 6 through the discharge port 405.

[0018] Two sets of crushing rollers 403 are movably installed inside the crushing cylinder 402, and the two sets of crushing rollers 403 are arranged in parallel; spur gear transmission modules 408 are installed on both sides of the crushing rollers 403, and the spur gear transmission modules 408 corresponding to the two sets of crushing rollers 403 mesh with each other; a bevel gear 404 is fixed at the end of the spur gear transmission module 408 away from the crushing rollers 403.

[0019] A connecting top cover 9 is placed on top of the outer cylinder 1, and a fixed gear ring 10 is fixed at the bottom of the connecting top cover 9. The fixed gear ring 10 meshes with the bevel gear 404 to form a transmission structure of "revolution driving rotation".

[0020] Drying system installation: Multiple sets of drying plates 12 are fixed on the inner wall of the outer cylinder 1. The drying plates 12 are evenly distributed along the circumference of the outer cylinder 1, and the inner side of the drying plates 12 extends into the interior of the lifting drying chamber 6. Multiple sets of air holes are opened on the inner side of the drying plates 12, and the air holes connect the interior of the drying plates 12 with the lifting drying chamber 6.

[0021] A fixed annular pipe 11 is fitted on the outside of the outer cylinder 1. The fixed annular pipe 11 is connected to each drying plate 12 one by one through multiple sets of connecting pipes 13. An input pipe 14 is fixed on the fixed annular pipe 11. The input pipe 14 is used to access the drying gas from the outside, so that the drying gas can enter the drying plate 12 through the fixed annular pipe 11 and the connecting pipe 13 in sequence, and then be blown into the lifting drying chamber 6 through the air hole.

[0022] Assembly of extrusion molding mechanism 7: The extrusion molding mechanism 7 includes a fixed frame 701, a forming annular plate 702, an extrusion roller 703, a discharge frame 704, and a drive ring 705. The fixed frame 701 is fixed to the bottom of the outer cylinder 1, and the forming annular plate 702 is installed at the bottom of the fixed frame 701. Multiple sets of forming holes are evenly opened on the surface of the forming annular plate 702 for extrusion molding of materials.

[0023] Multiple sets of extrusion rollers 703 are movably installed above the forming annular plate 702, and the multiple sets of extrusion rollers 703 are evenly distributed along the circumference of the forming annular plate 702; a drive ring 705 is sleeved on the outside of the multiple sets of extrusion rollers 703, and the drive ring 705 is movably connected to the extrusion rollers 703 to drive the extrusion rollers 703 to revolve.

[0024] A planetary speed-increasing gear module 8 is fitted on the outside of the transmission rod 407. The planetary speed-increasing gear module 8 includes a sun gear, a planet carrier, planet gears, and a ring gear carrier. The sun gear is fixedly connected to the base frame 15, the planet carrier is fixedly connected to the transmission rod 407, the planet gears are movably mounted on the planet carrier and mesh with the sun gear and the ring gear carrier respectively, and the ring gear carrier is fixedly connected to the drive ring 705. The speed-increasing rotation of the drive ring 705 is achieved through the planetary speed-increasing gear module 8.

[0025] The base frame 15 is fixed to the bottom of the fixed frame 701, and the discharge rack 704 is fixed to the outside of the base frame 15. One end of the discharge rack 704 extends to the bottom of the forming annular plate 702 to receive and discharge the formed material particles.

[0026] The working principle of this invention is as follows: When in use, the power is turned on, and a motor is installed inside the base frame 15. The output end of the motor is fixedly connected to the transmission rod 407. The operation of the motor can drive the transmission rod 407 to rotate. When the transmission rod 407 rotates, it can drive the rotating drum 401 to rotate through the plug-in frame 406. Since the crushing drum 402 is fixed inside the rotating drum 401, and the two sets of crushing rollers 403 rotating in opposite directions are movably installed inside the crushing drum 402, the motor can drive the rotating mechanism 4 to rotate as a whole. Furthermore, since spur gear transmission modules 408 are provided on both sides of the crushing roller 403, the two sets of crushing rollers 403 can rotate synchronously in opposite directions under the action of the spur gear transmission modules 408, thereby enabling the crushing operation of organic solid waste materials. The bevel gear 404 is connected to the spur gear transmission module 408. Since the fixed gear ring 10 is fixedly connected to the top cover 9, the fixed gear ring 10 will not rotate with the rotating mechanism 4. However, the two sets of bevel gears 404 revolve with the rotating mechanism 4. The bevel gears 404 and the fixed gear ring 10 mesh with each other. Then, under the action of the fixed gear ring 10, the two sets of bevel gears 404 rotate on their own, thereby driving the two sets of crushing rollers 403 to complete synchronous reverse rotation through the spur gear transmission module 408, so as to achieve the crushing effect of organic solid waste. After the organic solid waste material is crushed by the two sets of crushing rollers 403, it falls into the bottom of the fixed cylinder 201 through the discharge port 405 opened at the bottom of the rotating cylinder 401. At this time, the moisture in the material will be discharged to the outside through the permeable plate 202. Since the spiral blade 5 is fixed on the outer wall of the rotating cylinder 401, the spiral blade 5 rotates with the rotating cylinder 401. Under the action of the spiral blade 5, the bottom of the spiral blade 5 gradually captures the crushed material falling towards the top of the permeable plate 202. As the spiral blade 5 rotates, the crushed material is gradually lifted inside the lifting drying chamber 6. Meanwhile, multiple sets of drying plates 12 extend to the inner wall of the lifting drying chamber 6. Each set of drying plates 12 has multiple sets of air holes on its inner side. With the help of the fixed annular pipe 11 and multiple sets of connecting pipes 13, external drying gas can enter the fixed annular pipe 11 through the input pipe 14, and then be transported to the lifting drying chamber 6 through the multiple sets of drying plates 12. This allows the drying gas, i.e., hot air, to perform efficient drying of the crushed material during the lifting process. Furthermore, the spiral blade 5 has multiple sets of small holes evenly distributed on its surface. These small holes facilitate the passage of moisture or drying gas through the crushed material, thereby further improving the drying effect of the crushed material. Meanwhile, when the crushed material is lifted to the top by the spiral blades 5, the moisture content of the crushed material is greatly reduced, ensuring the drying effect of the material. At the same time, after the crushed material is lifted to the top of the fixed cylinder 201, the material will fall into the extrusion molding cavity 3. The bottom of the extrusion molding cavity 3 is equipped with an extrusion molding mechanism 7, which includes multiple sets of extrusion rollers 703 that rotate during the revolution. When the material falls to the top of the molding ring plate 702, the multiple sets of extrusion rollers 703 continuously extrude the material during the revolution. Since the molding ring plate 702 has uniformly opened molding holes on its surface, the material can be formed through the molding holes under the continuous rotation and extrusion of the extrusion rollers 703. The formed material is discharged and falls onto the discharge rack 704, so that the workers can collect the formed material in a concentrated manner. Furthermore, multiple sets of extrusion rollers 703 revolve as a whole through a drive ring 705, wherein the drive ring 705 is connected to the planetary speed-increasing gear module 8 for transmission. Specifically, the planetary speed-increasing gear module 8 includes a sun gear, multiple sets of planet gears, a planet carrier, and a ring gear carrier. The sun gear is located outside the transmission rod 407 and does not rotate with the transmission rod 407. Instead, it is fixedly connected to the base frame 15 via a connecting rod. In other words, the sun gear does not rotate. The planet carrier is fixedly connected to the transmission rod 407. When the transmission rod 407 rotates, it synchronously drives the planet carrier to rotate. Thus, the planet carrier drives multiple sets of planet gears to revolve around the sun while rotating on its own axis. The rotating planet gears then drive the ring gear carrier to rotate. As can be seen from the above, its core is to utilize the combined motion of planetary gear revolution and rotation, and amplify the output speed through the difference in the number of teeth between the gear ring carrier and the sun gear. In other words, at this time, the rotation of the drive ring 705 is greater than the rotation of the transmission rod 407, thereby improving the extrusion molding efficiency of the material. In summary, this equipment adopts an integrated design of core components such as outer cylinder 1, inner cylinder mechanism 2, rotating mechanism 4, and extrusion molding mechanism 7. It integrates the three core functions required for organic solid waste treatment—crushing, drying, and extrusion molding—into the same main body of the equipment. This eliminates the need for multiple independent devices and material transfer channels and operating gaps between devices. Compared with the existing technology of multiple devices being scattered, the space occupancy rate of the entire treatment system is significantly reduced. It is especially suitable for urban peripheries or industrial parks where land resources are scarce. This not only simplifies the difficulty of equipment layout but also greatly reduces site construction and equipment installation costs. Meanwhile, relying on the integrated operation process inside the equipment, organic solid waste is transferred from input into the equipment to the final formation of solid particles, and the entire process is completed inside the closed equipment: the crushed material falls directly into the fixed cylinder 201 through the discharge port 405 of the rotating cylinder 401, without the need for external transfer. Subsequently, driven by the spiral blades 5, the material is lifted and dried in the lifting and drying chamber 6 without needing to be transferred to a separate drying device; The dried material falls directly into the extrusion molding chamber 3 inside the equipment, eliminating the need for secondary transfer. The entire process avoids material spillage, residue, or flying loss caused by insufficient sealing of the transfer device, material scattering characteristics, and equipment connection gaps. In particular, it reduces the loss of fine crushed materials, which not only improves the resource utilization rate of organic solid waste, but also avoids secondary environmental pollution caused by scattered materials and reduces subsequent cleaning costs. Furthermore, on the one hand, the equipment drives the transmission rod 407 through a single motor to simultaneously realize multiple functions such as the overall rotation of the rotating mechanism 4, the synchronous reverse crushing of the crushing roller 403, the lifting of materials by the spiral blade 5, and the extrusion molding mechanism 7 revolving and extruding. All processes operate in coordination, eliminating the need to wait for material transfer between multiple devices, which greatly shortens the overall processing cycle. On the other hand, the planetary speed-increasing gear module 8 utilizes the combined motion of the planetary gears' revolution and rotation to amplify the output speed of the drive ring 705, thereby improving the extrusion molding efficiency of the extrusion roller shaft 703 on the material. At the same time, the small holes on the surface of the spiral blades 5 and the air hole design of the multiple sets of drying plates 12 enhance the contact area between the material and the drying gas, improve the drying efficiency, and reduce the drying energy consumption. Overall, the equipment improves processing efficiency while reducing power consumption and operating costs, making it more in line with the demand for efficient and economical organic solid waste treatment.
