Description

Technical Field

[0001] This invention relates to the field of organic waste treatment equipment technology, specifically to a co-processing equipment for kitchen waste and agricultural and forestry organic waste. Background Technology

[0002] In the field of resource recovery from kitchen waste and agricultural and forestry organic waste, existing technologies typically divide the pretreatment process into several independent steps. A common approach is to first perform preliminary solid-liquid separation through gravity sedimentation or mechanical pressing, and then transfer the separated solid material to the next stage for crushing via manual labor or additional conveying equipment.

[0003] However, this step-by-step traditional process has revealed its inherent limitations in practical applications. First, the entire pretreatment process lacks an integrated design, with separation, cleaning, and transfer steps disconnected from each other. This not only results in a lengthy processing cycle but also relies on manual intervention, has a low degree of automation, and cannot form a continuous and efficient workflow, thus limiting the overall processing efficiency from the source.

[0004] Secondly, there are insurmountable bottlenecks in the grading and conveying of materials during subsequent processing. Crushed materials, especially kitchen waste, are highly moist and viscous, making them prone to sticking and clogging when graded using traditional mechanical screens. This is an unavoidable and persistent problem; once it occurs, it leads to rapid failure of the screening function, large accumulation of material, and ultimately forces the entire equipment to shut down for cleaning.

[0005] Furthermore, the clogging problem of highly moist and viscous materials is not limited to screens. Material adhesion and aggregation are equally severe in various conveying channels within the system, especially at critical choke points such as narrow conveyor openings. Existing technologies often rely solely on the material's gravity or conventional vibration to promote flow, lacking proactive and mandatory anti-clogging measures. This leads to frequent equipment interruptions due to localized blockages during operation, severely impacting the long-term stability and reliability of the system. These issues collectively limit the automation level and adaptability of existing processing equipment to complex materials. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a co-processing device for kitchen waste and agricultural and forestry organic waste, which solves the problems of poor solid-liquid separation, low processing efficiency, easy wear and tear of equipment, and easy clogging of screens by highly wet and sticky materials during screening and blockage of key channels during transportation, resulting in poor overall operational stability.

[0018] This invention provides a device for the co-processing of kitchen waste and agricultural and forestry organic waste. It has the following beneficial effects:

[0019] 1. This invention achieves continuous automation of kitchen waste pretreatment by highly integrating centrifugal dehydration, mobile transfer and synchronous scraping cleaning functions. Compared with the traditional method that relies on static separation and manual transfer, this invention solves the problems of long processing cycle, incomplete separation and process disconnection, and greatly improves pretreatment efficiency.

[0020] 2. This invention replaces traditional screens with air separation by installing a high-pressure blower on the outside of the second processing chamber. When the crushed material falls, qualified light and fine powder is blown away and collected by the air, while unqualified heavy pieces fall directly and are sent back by the auger for further crushing. This method achieves the technical effects of precise grading and closed-loop circulation processing. Compared with the existing technology that uses mechanical screens, it fundamentally solves the stubborn problem of high-moisture materials easily clogging the screen, causing screening failure and equipment shutdown, and greatly improves the equipment's adaptability to complex materials.

[0021] 3. This invention, by incorporating a striking component driven by a third motor through a second transmission component, utilizes the intermittent meshing of incomplete gears and racks to periodically strike both conveyor inlets one and two, achieving stable operation of the equipment when processing high-moisture, high-viscosity materials. Compared to existing technologies that rely solely on gravity or vibration, which easily lead to blockages from wet waste, this invention effectively solves the problem of blockages in key channels caused by material adhesion, ensuring long-term, trouble-free operation of the entire co-processing equipment for kitchen waste and agricultural and forestry organic waste.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a co-processing device for kitchen waste and agricultural and forestry organic waste, including a first processing box 1 and a second processing box 5. A lifting device 2 is provided on the outside of the first processing box 1, and a rotating component and a moving component are provided inside the first processing box 1. The rotating component is used to separate the solid and liquid in the organic waste. After the rotating component finishes the solid-liquid separation, the moving component drives the scraper 19 to clean the drainage filter screen 42. At the same time, the first inclined plate 14 and the second inclined plate 13 provided on the outside cooperate with the first spring 17 to control the opening and closing of the baffle 15, so that the separated organic waste is transported to the top of the crushing component. After being processed by the crushing component, it falls into the screening component area, so that the unqualified organic waste enters the auger conveying component through the second conveying port 30 under the action of gravity, and is transported to the second conveying port 30 and falls above the crushing component for secondary crushing. At the same time, the crushing component drives the striking component through the second transmission component to reciprocate to strike the first conveying port 31 and the second conveying port 30.

[0033] The moving component includes a support frame 3 and a baffle 15. The outer side of the baffle 15 is slidably connected to the inside of the first processing box 1. A second limiting plate 16 is fixed to the bottom of the baffle 15. Multiple first springs 17 are fixed to the bottom of the second limiting plate 16. The outer side of the support frame 3 is fixed to the outside of the first processing box 1. An electric push rod 4 is fixed to the inner wall of the support frame 3. A connecting plate 6 is fixed to the output end of the electric push rod 4. A first limiting ring 10 is fixed to the outer side of the connecting plate 6. A toothed ring 11 is rotatably connected to the inner wall of the first limiting ring 10. A water filter cylinder 12 is fixed to the inner wall of the toothed ring 11. A first inclined plate 14 is fixed to one side of the first limiting ring 10. A second inclined plate 13 is fixed to the other side of the first limiting ring 10. The bottom surfaces of the first inclined plate 14 and the second inclined plate 13 are flush with the bottom surface of the water filter cylinder 12. A thin shell 18 is fixed to the outer side of the connecting plate 6. A scraper 19 is slidably connected inside the thin shell 18. Multiple second springs 20 are fixed to the top of the scraper 19.

[0034] Specifically, the lifting device 2 is used to lift and feed externally collected kitchen waste and agricultural and forestry organic waste into the first processing tank 1. The first processing tank 1 serves as a container for the pre-treatment stage, providing space for solid-liquid separation and material transfer. The rotating assembly applies centrifugal force to the organic waste in the first processing tank 1, efficiently separating its liquid components, such as water and oil, from the solid phase. After solid-liquid separation, the moving assembly, as the core actuator, drives the entire dewatering assembly in linear motion to achieve automatic material transfer and equipment self-cleaning. In the moving assembly, the support frame 3 provides a stable mounting base for the drive source; the electric push rod 4, as the main power source, outputs precise linear push-pull force to drive the connecting plate 6 in reciprocating motion, thereby initiating the entire material transfer and screen cleaning process. The connecting plate 6 is a multi-functional bearing platform used to integrate and drive multiple components related to dewatering, screen scraping, and unloading to move synchronously. The first limiting ring 10, as a rotating support structure, ensures that the toothed ring 11 can rotate freely while being translated by the connecting plate 6. The gear ring 11 serves as a transmission component, transmitting power from the rotating assembly to the filter cylinder 12. The filter cylinder 12 is the core container for centrifugally drying organic waste; its sidewalls form the drain filter screen 42, which allows liquid to pass through while intercepting solid materials during rotation. The thin shell 18 is a cover mounted on the connecting plate 6, used to house and guide the scraper 19. The core function of the scraper 19 is to adhere closely to and scrape away residual material adhering to the surface of the drain filter screen 42 during the movement of the moving assembly, preventing clogging and maintaining good permeability. The second spring 20 provides continuous elastic pressure to the scraper 19, ensuring it always maintains effective contact with the drain filter screen 42. The baffle 15 acts as an automatic door, controlling the opening and closing of the passage between the first processing tank 1 and the second processing tank 5. The first inclined plate 14 and the second inclined plate 13 are ingenious mechanical linkages, cleverly driving the baffle 15 to open or close during the reciprocating motion of the moving assembly through contact with it. The second limiting plate 16 is an accessory to the baffle 15, providing a base point for the first spring 17. The first spring 17 provides a restoring force to the baffle 15, ensuring it automatically returns to the closed state when no external force is applied. When the material enters the second processing box 5, which serves as the deep processing zone, the crushing assembly powerfully crushes large solid materials, reducing their particle size. The crushed material is then classified in the screening assembly area by air separation or gravity. For non-conforming materials, the second conveyor port 30 serves as the inlet of the circulation system, accurately guiding these materials to the auger conveyor assembly. The auger conveyor assembly forcibly lifts these non-conforming materials from the bottom of the equipment and returns them to the top of the crushing assembly for further crushing, forming a closed-loop circulation. To ensure material flowability at critical locations, the striking assembly is configured to periodically and actively physically impact the easily clogged conveyor ports 31 and 30 to break up material adhesion and bridging.The second transmission component is used to extract a portion of the power from the power source of the crushing component and transmit it to the striking component to drive its operation.

[0035] Please see the appendix Figure 3 and attached Figure 7 The rotating assembly includes a fixed frame 7, the top of which is fixed to the bottom of the connecting plate 6, a first motor 8 is fixed to the bottom of the fixed frame 7, a first gear 9 is fixed to the output end of the first motor 8, and the first gear 9 is meshed with the gear ring 11.

[0036] Specifically, the rotating assembly, as a core functional module, provides stable and efficient rotational power to the filter cylinder 12, generating a strong centrifugal force field to achieve solid-liquid separation. The mounting frame 7 within this assembly serves as a rigid support structure, primarily providing a stable mounting base for the first motor 8 and ensuring that it does not vibrate or shift during operation, thus guaranteeing a precise meshing distance and positional relationship between its output shaft and the gear ring 11. The first motor 8 serves as the power source for the entire rotating assembly, starting upon receiving instructions from the control system and converting electrical energy into high-speed mechanical energy. The first gear 9 acts as the drive transmission wheel, stably transmitting the torque and speed output by the first motor 8. Through the reliable meshing transmission between the first gear 9 and the gear ring 11, the power of the first motor 8 is transmitted to the filter cylinder 12 without loss. The purpose of this gear transmission design is to precisely convert the rotational motion of the motor into the high-speed rotation of the coaxial filter cylinder 12, which ultimately generates centrifugal force inside the cylinder that meets the process requirements. This force tightly throws the solid particles in the organic waste toward and adheres to the drainage filter screen 42, while the liquid phase passes through the filter screen and is discharged, achieving a rapid and thorough solid-liquid separation effect.

[0037] Please see the appendix Figure 3 and attached Figure 7 The crushing assembly includes a third motor 45 and two crushing rollers 44. The outer side of the crushing rollers 44 is rotatably connected to the inside of the second processing box 5. The outer side of the third motor 45 is fixed to the second processing box 5. A second gear 22 is fixed to the outer side of the crushing rollers 44. The two second gears 22 are meshed and connected. The output end of the third motor 45 is fixed to one end of one of the crushing rollers 44 away from the second gear 22.

[0038] Specifically, the crushing assembly is used to efficiently mechanically crush the dehydrated organic waste transferred from the first processing tank 1, aiming to process it from large pieces into fine particles that meet the requirements of subsequent air classification. The third motor 45 within this assembly serves as an independent power source for the entire crushing operation, its core function being to provide a powerful and stable torque output to drive the crushing system. Two crushing rollers 44 are the core working components for performing the crushing task. By rotating in opposite directions, they utilize specially designed teeth, grooves, or textures on their roller surfaces to apply strong squeezing, shearing, and tearing forces to the material entering them, thereby achieving forced crushing. The second gear 22 is used to achieve power synchronization and reverse transmission between the two crushing rollers 44. Specifically, when the third motor 45 drives one of the driving crushing rollers 44 to rotate, the meshing between the two second gears 22 precisely transmits power to the other driven crushing roller 44, ensuring that the two rollers rotate in opposite directions at the same angular velocity, forming a highly efficient material biting and crushing zone, entraining and thoroughly crushing the material.

[0039] Please see the appendix Figure 4 and attached Figure 8 The striking assembly includes a connecting plate 36, the outer side of which is fixed to the outer side of the second processing box 5. A second rotating rod 35 is rotatably connected inside the connecting plate 36. An incomplete gear 39 is fixed to the outer side of the second rotating rod 35. A movable frame 37 is slidably connected inside the connecting plate 36. Two striking rods 40 are fixed to the outer side of the movable frame 37. Two racks 38 are fixed to the inner wall of the movable frame 37. The incomplete gear 39 and the racks 38 are meshed together.

[0040] Specifically, the striking component, as an active anti-clogging module, generates regular reciprocating impacts to effectively break up adhesions or blockages formed by highly moist and sticky materials at conveying bottlenecks. The connecting plate 36 within the component acts as a rigid mounting frame, providing stable support and precise guidance for all internal moving parts. The second rotating rod 35 introduces continuous rotational power from the external transmission system into this component. The incomplete gear 39 is the core element for intermittent motion conversion, transforming its own continuous rotational motion into discontinuous meshing with the rack 38. The moving frame 37 acts as a linear slider, supporting the rack 38 and the final actuator, the striking rod 40. The entire working mechanism is that the incomplete gear 39 meshes with the rack 38 in its toothed section, driving the moving frame 37 to drive the striking rod 40 to generate a rapid impact stroke; while in its toothless section, the meshing relationship is released, allowing the moving frame 37 to reset. This cycle repeats, and finally the striking rod 40 performs periodic and efficient striking on the material channel, thereby ensuring the smooth flow of material transportation.

[0041] Please see the appendix Figure 2 and attached Figure 7The transmission assembly 2 includes a third pulley 32, a fourth pulley 33, and a protective cover 41. The outer side of the protective cover 41 is fixed to the outer side of the second processing box 5. The outer side of the third pulley 32 is fixed to the outer side of one of the crushing rollers 44. The outer side of the fourth pulley 33 is fixed to the outer side of the second rotating rod 35. The fourth pulley 33 and the third pulley 32 are connected by a second belt 34.

[0042] Specifically, transmission component two achieves a clever power distribution. Its core function is to divert power from the crushing component's power system and stably transmit it to the striking component, thereby driving the striking component. This eliminates the need for an additional motor for the striking component, achieving efficient energy utilization and simplifying the overall structure of the equipment. The third pulley 32 within this component serves as the driving pulley, capturing the rotational kinetic energy of the crushing roller 44 in real time, acting as the power source for the entire transmission chain. The fourth pulley 33 serves as the driven pulley, receiving the power transmitted through the second belt 34 and transmitting it losslessly to the second rotating rod 35 of the striking component. The second belt 34 acts as a flexible transmission medium, not only precisely transmitting torque and motion but also utilizing its elasticity to buffer and dampen shocks generated during system operation, protecting the components at both ends. The protective cover 41 is used to provide necessary safety isolation. Its main purpose is to isolate the high-speed rotating pulleys and belts from the external environment to prevent operators from accidentally touching them and causing injury. At the same time, it can also effectively block dust and moisture generated during the process from entering the transmission system, ensuring its operational reliability and service life.

[0043] Please see the appendix Figure 3 The auger conveying assembly includes an auger cylinder 26, the outer side of which is fixed to the outer side of the conveying port 2 30. A second motor 27 is fixed to the top of the auger cylinder 26, and an auger shaft 28 is fixed to the output end of the second motor 27. Spiral blades 29 are fixed to the outer side of the auger shaft 28.

[0044] Specifically, the auger conveyor assembly is used to construct a crucial closed-loop circulation system. Its core function is to forcibly lift the substandard materials that have settled after air classification from the lower conveyor port 30 of the equipment back to the upper crushing component inlet for secondary crushing. The auger cylinder 26 within this assembly serves as a sealed conveying channel, providing a trajectory for the directional movement of materials and effectively preventing material spillage and dust overflow during the conveying process. The second motor 27 serves as the independent power source for this conveying assembly, its main function being to provide strong and continuous torque. The auger shaft 28 transmits the torque output from the second motor 27, acting as the central frame for rotation. The spiral blades 29 are the direct working components performing the conveying task, converting the rotational motion of the auger shaft 28 into continuous axial thrust on the material. Through this positive displacement, even substandard materials with a certain degree of viscosity and large particle size can be forcibly and stably conveyed upwards along the inner wall of the auger cylinder 26, ensuring that 100% of the substandard materials are returned to the crushing stage, guaranteeing the uniformity of the final output quality.

[0045] Please see the appendix Figure 1 and Figure 8 The scraper 19 and the drainage filter 42 are always in contact. The bottom end of the first spring 17 is fixed to the inner wall of the first treatment box 1. The outer side of the second treatment box 5 is fixedly connected to the protective shell 21. The end of the second spring 20 away from the scraper 19 is fixed to the inner top wall of the thin shell 18. The lower part of the outer side of the first treatment box 1 is provided with a box door 43. The outer side of the connecting plate 6 is slidably connected to the inner wall of the first treatment box 1. The outer side of the connecting plate 6 is slidably connected to the inside of the second treatment box 5.

[0046] Specifically, the second spring 20 provides a continuous and stable preload for the scraper 19. Its core function is to ensure that the blade of the scraper 19 remains tightly fitted to the inner surface of the drainage filter screen 42 throughout its reciprocating motion, thereby achieving efficient and thorough scraping and cleaning of the filter screen. The first spring 17 serves as a reset device for the baffle 15. Its function is to quickly push the baffle 15 back to its initial closed position using its stored elastic energy after the unloading action is completed and the first inclined plate 14 disengages, ensuring a reliable seal of the material channel. The sliding characteristics of the connecting plate 6 are fundamental to automated transfer. Its function is to act as a guide and load-bearing platform for linear motion, guiding the entire moving assembly to reciprocate smoothly and precisely between the first processing box 1 and the second processing box 5. The protective shell 21 is used to safely isolate the moving parts such as the transmission mechanism outside the second processing box 5, aiming to protect operators from potential mechanical injury and prevent external impurities from affecting equipment operation. The door 43 is a convenient access point for maintenance and repair. Its main function is to allow staff to easily open and access the interior space of the first processing box 1 when necessary to carry out cleaning or maintenance work.

[0047] Working principle: First, kitchen waste and agricultural and forestry organic waste are fed into the filter cylinder 12 inside the first treatment tank 1 via the lifting device 2. Then, the rotating assembly starts working; the first motor 8 inside drives the first gear 9, which meshes with the gear ring 11, causing the filter cylinder 12 to rotate at high speed. Through centrifugal force, liquid water or oil in the waste is ejected and separated into solid and liquid phases through the drainage filter screen 42.

[0048] After solid-liquid separation is completed, the electric push rod 4 in the moving assembly is activated, pushing the connecting plate 6 and the entire filter cylinder 12 assembly fixed thereto towards the second processing tank 5. During the movement, the scraper 19, fixed inside the thin shell 18 and held in place by the second spring 20, will adhere to and scrape the surface of the drainage filter screen 42, achieving automatic cleaning. At the same time, the first inclined plate 14 on one side of the connecting plate 6 will press against the baffle 15, overcoming the elastic force of the first spring 17 to open the baffle 15, and the dewatered material in the filter cylinder 12 will fall onto the crushing assembly of the second processing tank 5. After the material transfer is completed, the electric push rod 4 resets. During the reset process, the second inclined plate 13 on the other side will act on the baffle 15 again. After the filter cylinder 12 has completely retracted, the baffle 15 resets and closes under the action of the first spring 17.

[0049] After the material enters the second processing chamber 5, the third motor 45 of the crushing assembly starts, driving the two crushing rollers 44 to rotate in opposite directions through the meshing second gear 22, thus powerfully crushing the material. The crushed material falls downwards, at which point the screening assembly located on the side wall of the second processing chamber 5 begins to work, and its high-pressure blower 25 generates a strong airflow that blows horizontally across the falling material. Powder with the correct particle size and low specific gravity is blown into the feed pipe 24 by the airflow and conveyed to the cyclone separator 23 for collection; while larger, less crushed, and heavier materials fall directly due to inertia.

[0050] These heavy materials fall into the lower conveyor port 30 and enter the auger conveyor assembly. The second motor 27 of the auger conveyor assembly drives the auger shaft 28 and the spiral blades 29 to forcibly lift these unqualified materials through the auger cylinder 26 and send them back to the top of the crushing assembly for secondary crushing, forming a closed loop until all materials are processed to meet the standards.

[0051] To ensure smooth system operation, the crushing component drives the striking component via the second transmission component. The rotation of one crushing roller 44 is transmitted to the second rotating rod 35 via the third pulley 32, the second belt 34, and the fourth pulley 33. The incomplete gear 39 on the second rotating rod 35 intermittently meshes with the rack 38 on the moving frame 37, driving the striking rod 40 to reciprocately strike the conveyor port 31 where the material enters the second processing box and the conveyor port 30 where it enters the circulation system, effectively preventing wet and sticky materials from clogging at key bottlenecks.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
