Abstract
Description
Technical Field
[0001] This invention belongs to the field of composting technology, specifically relating to a drum-type continuous turning aerobic composting device. Background Technology
[0002] In the fields of agricultural production, livestock and poultry breeding, and urban organic waste treatment, composting is an important technical means to realize the resource utilization of waste and reduce environmental pollution. Among them, aerobic composting is widely used in the harmless and resource-based treatment of various organic wastes due to its advantages such as high composting efficiency, good product quality, and no secondary pollution. The core requirements of aerobic composting are to ensure sufficient oxygen inside the compost pile and uniform material mixing, while achieving continuous operation to improve composting efficiency, reduce labor costs, and meet the actual needs of large-scale treatment. Currently, existing aerobic composting equipment is mainly divided into fixed bed type, turner type, and drum type. Among them, drum composting equipment has become the preferred equipment for small and medium-sized composting scenarios due to its compact structure, small footprint, and relatively uniform turning effect. However, existing drum composting devices mostly have fixed turning structures. The rotating drum only achieves simple tumbling of the material, making it difficult to fully break up and mix the pile. This leads to localized clumping and poor ventilation within the pile, resulting in localized anaerobic fermentation. This not only reduces composting efficiency but also produces odors, impacting the surrounding environment. Furthermore, the ventilation methods are mostly passive or fixed-position, unable to dynamically adjust the ventilation location and volume according to the pile's turning state. This results in uneven oxygen distribution within the pile, with excessive oxygen near the ventilation openings and oxygen deficiency in areas further away, further affecting composting effectiveness. Summary of the Invention
[0003] The purpose of this invention is to provide a drum-type continuous turning aerobic composting device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a drum-type continuous turning aerobic composting device, comprising a guide frame, a turning frame slidably connected to the outside of the guide frame, a drum body rotatably connected to the inside of the turning frame, an air-venting component at the top of the turning frame, and a shaking component on one side of the turning frame.
[0005] In a preferred embodiment, the guide frame is provided with guide grooves on both sides, and the flipping frame is fixedly connected to the drive frame which is slidably connected to the outside of the guide grooves on both sides. The drive frame is provided with a drive box facing outwards, and the top and bottom of the inner cavity of the drive frame are provided with moving wheels that fit with the guide grooves.
[0006] In a preferred embodiment, a motor is fixedly connected to one side of the top of the turning frame, a rotating column is fixedly connected to the output shaft of the motor, a driving gear is fixedly connected to the outside of the rotating column, a driven gear is fixedly connected to the outside of one side of the drum body, and the driven gear and the driving gear are connected by a transmission belt.
[0007] In a preferred embodiment, the ventilation assembly includes an air box fixedly connected to the top of the turning frame. Inside the air box, a plurality of piston sleeves facing the main body of the roller are fixedly connected at equal intervals. The bottom end of each piston sleeve is provided with a one-way valve that only allows outflow and not inflow.
[0008] In a preferred embodiment, an eccentric plate is fixedly connected above each piston sleeve of the rotating column. A connecting rod is rotatably connected to the outside of the eccentric part of the eccentric plate. A movable piston that is slidably connected inside the piston sleeve is hinged to the bottom end of the connecting rod, and the movable pistons inside every two adjacent piston sleeves are staggered and distributed vertically.
[0009] In a preferred embodiment, one side of the piston sleeve is provided with a connecting pipe that communicates with the inside of the air box, and one side of the top of the air box is provided with an air inlet pipe.
[0010] In a preferred embodiment, a first bevel gear is fixedly connected to the other end of the rotating column, a central column is rotatably connected inside the throwing frame, a second bevel gear that meshes with the first bevel gear is fixedly connected to the top of the central column, and a half gear is fixedly connected to the bottom end of the rotating column.
[0011] In a preferred embodiment, the shaking assembly includes a side groove disposed on one side of the turning frame, a side shift plate disposed on one side of the side groove, a movable plate slidably connected to one side of the side shift plate, and a mating tooth that meshes with the half gear on the side of the movable plate facing the half gear.
[0012] In a preferred embodiment, a collision cone is fixedly connected to one side of the side-shifting plate facing the throwing frame, a force-bearing platform is fixedly connected to the side of the throwing frame facing the collision cone, and a guide post is fixedly connected to the side of the side-shifting plate facing the throwing frame and slidably connected inside the throwing frame, with a spring sleeved on the outside of the guide post.
[0013] In a preferred embodiment, multiple sets of turning arms are fixedly connected in a ring at equal intervals on the outside of the drum body, and each turning arm is fixedly connected to a turning tooth at its end.
[0014] Compared with the prior art, the beneficial effects of the present invention are: This drum-type continuous turning aerobic composting device, by setting up a guide frame, a turning frame, and a drive component, allows the turning frame to slide along the guide frame. In conjunction with the rotation of the drum body, it expands the turning coverage area. At the same time, the turning arms and turning teeth on the outside of the drum body can fully disperse and mix the materials, effectively solving the problems of insufficient turning and easy material agglomeration in existing devices, improving the uniformity of material mixing, and providing a good foundation for aerobic composting.
[0015] This drum-type continuous turning aerobic composting device uses an aeration component. A motor drives a rotating column to rotate an eccentric plate, which in turn pushes a moving piston to reciprocate within a piston sleeve, achieving active aeration. The moving pistons of adjacent piston sleeves are staggered and distributed vertically, allowing the aeration position to be dynamically adjusted according to the tumbling state of the compost pile. This ensures a more uniform distribution of oxygen within the pile, avoids localized anaerobic fermentation, improves composting efficiency and product quality, and simplifies the driving method of the aeration structure, thus reducing energy consumption.
[0016] This drum-type continuous turning aerobic composting device, through the setting of a shaking component, uses a rotating column to drive a half gear to rotate, and in conjunction with the cooperating gear, spring and other structures to drive the side plate to move back and forth, so that the collision cone and the force-bearing platform repeatedly collide. The resulting vibration can shake off the material adsorbed on the inner wall of the drum and the surface of the turning components, reduce the accumulation of material adsorption, reduce turning resistance and energy consumption. At the same time, this component shares a power source with the drum and the aeration component, reducing the number of power sources required, reducing the manufacturing and maintenance costs of the device, and improving operational stability.

[0019] The present invention will be further described below with reference to embodiments.
[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0021] Please see Figures 1-6This invention provides a drum-type continuous turning aerobic composting device, including a guide frame 1, a turning frame 2 slidably connected to the outside of the guide frame 1, a drum body 4 rotatably connected inside the turning frame 2, a ventilation component at the top of the turning frame 2, guide grooves 101 on both sides of the guide frame 1, a drive frame 3 slidably connected to the outside of the guide grooves 101 on both sides of the turning frame 2, a drive box 301 facing outwards on the drive frame 3, and movable wheels 302 fitted to the guide grooves 101 at the top and bottom of the inner cavity of the drive frame 3, a motor 5 fixedly connected to one side of the top of the turning frame 2, a rotating column 501 fixedly connected to the output shaft of the motor 5, a drive gear 502 fixedly connected to the outside of the rotating column 501, a driven gear 4001 fixedly connected to the outside of one side of the drum body 4, and a transmission belt 503 connecting the driven gear 4001 and the drive gear 502. The ventilation assembly includes an air box 504 fixedly connected to the top of the turning frame 2. Inside the air box 504, multiple piston sleeves 505 facing the drum body 4 are fixedly connected at equal intervals. The bottom of the piston sleeve 505 is provided with a one-way valve that only allows outflow and not inflow. The rotating column 501 is located above each piston sleeve 505 and is fixedly connected with an eccentric plate 506. The eccentric part of the eccentric plate 506 is rotatably connected to a connecting rod 507. The bottom end of the connecting rod 507 is hinged to a movable piston 508 that is slidably connected inside the piston sleeve 505. The movable pistons 508 inside every two adjacent piston sleeves 505 are staggered and distributed vertically. One side of the piston sleeve 505 is provided with a connecting pipe that communicates with the inside of the air box 504. One side of the top of the air box 504 is provided with an air inlet pipe. Multiple sets of turning arms 401 are fixedly connected in a ring at equal intervals outside the drum body 4. The end of each turning arm 401 is fixedly connected with a turning tooth 402. During operation, the drive box 301 on the outside of the drive frame 3 provides power, driving the moving wheels 302 at the top and bottom of the inner cavity of the drive frame 3 to roll along the guide grooves 101 on both sides of the guide frame 1, thereby driving the turning frame 2 to slide back and forth along the guide frame 1; at the same time, the motor 5 on the top side of the turning frame 2 starts, and its output shaft drives the rotating column 501 to rotate. The drive gear 502 outside the rotating column 501 drives the driven gear 4001 on one side of the drum body 4 to rotate through the transmission belt 503, so that the drum body 4 rotates at a uniform speed inside the turning frame 2. The turning arms 401 and the turning teeth 402 at the ends of the drum body 4 are distributed in a ring shape at equal intervals outside the drum body 4, and they rotate with the drum body 4 to break up and turn the internal materials. The reciprocating sliding of the turning frame 2, combined with the rotation of the drum body 4, greatly expands the turning coverage area, preventing local materials from being missed. The combination of the turning arm 401 and the turning teeth 402 effectively breaks up material clumps, making the material mix more even. This solves the problems of insufficient turning and easy material clumping in existing devices, providing a uniform material base for subsequent aerobic fermentation. At the same time, the drive structure operates smoothly, enabling continuous turning operations and improving composting efficiency. While the motor 5 drives the rotating column 501 to rotate, multiple eccentric plates 506 fixed on the rotating column 501 rotate synchronously with it. The connecting rod 507 connected to the eccentric part of the eccentric plate 506 is driven to swing back and forth, thereby pulling the hinged moving piston 508 to slide up and down in the piston sleeve 505 inside the air box 504. Outside air enters the air box 504 through the air inlet pipe on one side of the top of the air box 504, and then enters each piston sleeve 505 through the connecting pipe on one side of the piston sleeve 505. When the moving piston 508 moves downward, the air pressure inside the piston sleeve 505 increases, pushing the one-way valve at the bottom to open, blowing air into the material inside the drum body 4. The moving pistons 508 in each two adjacent piston sleeves 505 are staggered and distributed up and down, so that the ventilation action of each piston sleeve 505 is alternate. The active ventilation method, compared to existing passive or fixed-position ventilation, can actively deliver oxygen into the material. The staggered moving pistons 508 can dynamically adjust the ventilation position, making the oxygen distribution inside the pile more uniform. This effectively avoids anaerobic fermentation in some areas due to lack of oxygen, reduces odor generation, and improves composting efficiency and product quality. The ventilation component and the drum body 4 share the same motor 5 as the power source, eliminating the need for an additional power mechanism, simplifying the device structure, and reducing energy consumption and manufacturing costs.
[0022] Please see Figures 1-6 A shaking assembly is provided on one side of the turning frame 2. A first bevel gear 509 is fixedly connected to the other end of the rotating column 501. A central column 5011 is rotatably connected inside the turning frame 2. A second bevel gear 5010 that meshes with the first bevel gear 509 is fixedly connected to the top of the central column 5011. A half gear 5012 is fixedly connected to the bottom end of the rotating column 501. The shaking assembly includes a side groove 202 provided on one side of the turning frame 2. A side shift plate 6 is provided on one side of the side groove 202. A sliding plate is fixedly connected to one side of the side shift plate 6. A movable plate 604 is connected inside the side groove 202. The movable plate 604 has a mating tooth 605 that meshes with the half gear 5012 on the side facing the half gear 5012. A collision cone 603 is fixedly connected to both sides of the side plate 6 on the side facing the throwing frame 2. A force-bearing platform 201 is fixedly connected to the side of the throwing frame 2 on the side facing the collision cone 603. A guide post 601 that is slidably connected inside the throwing frame 2 is fixedly connected to the side plate 6 on the side facing the throwing frame 2, and a spring 602 is sleeved on the outside of the guide post 601. When the rotating column 501 rotates, the first bevel gear 509 fixed at its other end drives the meshing second bevel gear 5010 to rotate, which in turn drives the central column 5011 inside the turning frame 2 to rotate. The half gear 5012 at the bottom of the central column 5011 rotates synchronously with it. During the rotation of the half gear 5012, it periodically meshes with the mating teeth 605 on the moving plate 604, pushing the moving plate 604 to reciprocate along the side groove 202 on one side of the turning frame 2. The moving plate 604 drives the side plate 6 to reciprocate synchronously. The collision cones 603 on both sides of the side plate 6 move with the side plate 6 and repeatedly collide with the force platform 201 on the turning frame 2, generating vibration. At the same time, the guide column 601 on the side plate 6 slides along the inside of the turning frame 2, and the spring 602 on its outside plays a buffering and restoring role, ensuring that the side plate 6 reciprocates smoothly. The vibration generated by the collision can quickly shake off the material adsorbed on the inner wall of the drum body 4, the surface of the turning arm 401 and the turning teeth 402, avoiding the accumulation of material which would increase the turning resistance and energy consumption. At the same time, it can prevent the adsorbed material from failing to participate in the composting process and thus prevent the growth of bacteria, ensuring the purity of the compost products. This shaking component also shares the same power source as the motor 5, further reducing the number of power sources required, lowering the maintenance cost and failure rate of the device, improving the overall operational stability of the device, and the buffering effect of the spring 602 can reduce the wear caused by the collision and extend the service life of the device.
[0023] The working principle and usage process of this invention are as follows: First, when working, the drive box 301 on the outside of the drive frame 3 provides power, which drives the moving wheels 302 at the top and bottom of the inner cavity of the drive frame 3 to roll along the guide grooves 101 on both sides of the guide frame 1, thereby driving the turning frame 2 to slide back and forth along the guide frame 1; at the same time, the motor 5 on the top side of the turning frame 2 starts, and its output shaft drives the rotating column 501 to rotate. The driving gear 502 outside the rotating column 501 drives the driven gear 4001 on one side of the drum body 4 to rotate through the transmission belt 503, so that the drum body 4 rotates at a uniform speed inside the turning frame 2. The turning arms 401 and the turning teeth 402 at the ends of the drum body 4 are distributed in a ring shape at equal intervals outside the drum body 4, and the internal materials are broken up and turned over as the drum body 4 rotates. While the motor 5 drives the rotating column 501 to rotate, multiple eccentric plates 506 fixed on the rotating column 501 rotate synchronously with it. The connecting rod 507 connected to the eccentric part of the eccentric plate 506 is driven to swing back and forth, thereby pulling the hinged moving piston 508 to slide up and down in the piston sleeve 505 inside the air box 504. Outside air enters the air box 504 through the air inlet pipe on one side of the top of the air box 504, and then enters each piston sleeve 505 through the connecting pipe on one side of the piston sleeve 505. When the moving piston 508 moves downward, the air pressure inside the piston sleeve 505 increases, pushing the one-way valve at the bottom to open, blowing air into the material inside the drum body 4. The moving pistons 508 in each two adjacent piston sleeves 505 are staggered and distributed up and down, so that the ventilation action of each piston sleeve 505 is alternate. When the rotating column 501 rotates, the first bevel gear 509 fixed at its other end drives the meshing second bevel gear 5010 to rotate, which in turn drives the central column 5011 inside the turning frame 2 to rotate. The half gear 5012 at the bottom of the central column 5011 rotates synchronously with it. During the rotation of the half gear 5012, it periodically meshes with the mating teeth 605 on the moving plate 604, pushing the moving plate 604 to reciprocate along the side groove 202 on one side of the turning frame 2. The moving plate 604 drives the side plate 6 to reciprocate synchronously. The collision cones 603 on both sides of the side plate 6 move with the side plate 6 and repeatedly collide with the force platform 201 on the turning frame 2, generating vibration. At the same time, the guide column 601 on the side plate 6 slides along the inside of the turning frame 2, and the spring 602 on its outside plays a buffering and restoring role, ensuring that the side plate 6 reciprocates smoothly.
