[0002] Agricultural solid waste (hereinafter referred to as "agricultural solid waste") mainly includes straw and livestock manure, etc., and its pretreatment and carbonization are the core links to realize resource utilization (such as the preparation of biochar and energy recovery). The goal of pretreatment is to remove impurities and adjust the material properties to provide uniform and efficient raw materials for subsequent carbonization; carbonization is pyrolysis under anaerobic / anoxic conditions to convert organic components into products such as biochar.

[0003] Current agricultural solid waste treatment requires the centralized transportation of solid waste to treatment stations. Existing treatment stations have high construction costs, require a variety of equipment to achieve processes such as drying, crushing, screening and carbonization of solid waste, have long construction cycles and low integration levels. Summary of the Invention

This system adopts an integrated containerized form, has a short construction period, low cost, and is suitable for solid waste treatment scenarios such as rural areas and islands. It can combine the drying, crushing, and screening processes with the carbonization process, resulting in a high degree of integration.

[0015] Preferably, the bottom front and rear sides of the first annular heat insulation cover are respectively provided with an arc-shaped screen and a straw feeding port. An opening and closing component is installed in the straw feeding port, and the arc-shaped screen is used to screen out impurities in the chopped straw.

[0016] Preferably, the bottom front and rear sides of the second annular heat insulation cover are respectively provided with a metal impurity filter assembly and a fecal particle discharge port. The metal impurity filter assembly includes multiple arc-shaped openings equidistantly opened on the bottom front side of the second annular heat insulation cover. The top of the arc-shaped openings is provided with an arc-shaped mesh flush with the inner surface of the second annular heat insulation cover. The bottom of the second annular heat insulation cover is equipped with an arc-shaped electromagnetic suction plate that opens and closes multiple arc-shaped openings. The inner side of the arc-shaped electromagnetic suction plate is attached to the outer wall of the second annular heat insulation cover. An annular screen is installed on the rear side of the second annular pretreatment box. Multiple grinding balls are installed in multiple fecal chambers of the second annular pretreatment box. The extreme position of the second annular pretreatment box swinging backward does not reach the fecal particle discharge port.

[0017] Preferably, a second motor is installed on the top of the second annular heat insulation cover, a second gear is fixed at the output end of the second motor, a third gear ring that meshes with the second gear is fixed on the front side of the second annular heat insulation cover, and the arc-shaped electromagnetic suction plate is fixedly installed on the side wall of the third gear ring.

[0018] Preferably, the bottom of the arc-shaped screen and the multiple arc-shaped openings are respectively covered with a first arc-shaped discharge cover and a second arc-shaped discharge cover. The discharge ends of the first arc-shaped discharge cover and the second arc-shaped discharge cover extend out of the container. The bottom of the straw discharge port and the manure pellet discharge port are respectively covered with a first arc-shaped discharge cover and a second arc-shaped discharge cover. An upwardly inclined auger conveyor is fixedly installed at the bottom of the container. The discharge ends of the first arc-shaped discharge cover and the second arc-shaped discharge cover are both connected to the auger conveyor, and the conveying and mixing are completed inside the auger conveyor. The discharge end of the auger conveyor extends out of the front side of the container.

[0019] Preferably, the container also integrates an exhaust gas treatment module and a remote controller. The exhaust gas treatment module is used to treat carbonization exhaust gas, and the remote controller is used to control the rotation speed and temperature of the electromagnetic heating rotary carbonization furnace, supporting remote parameter control via the Internet of Things.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The container integrates an electromagnetic heating rotary carbonization furnace, a first annular insulation cover, a first annular pretreatment box, a second annular insulation cover, a second annular pretreatment box, an exhaust gas treatment module, and a remote controller. It adopts a containerized integrated form, which has a short construction period, low cost, and the container is easy to transport and flexible. It is suitable for solid waste treatment scenarios such as rural areas and islands. It can combine the drying, crushing, and screening processes with the carbonization process, with a high degree of integration and supports remote parameter control via the Internet of Things.

[0022] 2. By installing an electromagnetic heating rotary carbonization furnace, a first annular heat insulation cover, a first annular pretreatment box, a second annular heat insulation cover, and a second annular pretreatment box, the electromagnetic heating rotary carbonization furnace facilitates temperature control and reduces pollution. The front and rear sections of the electromagnetic heating rotary carbonization furnace are respectively a low-temperature section and a high-temperature section. The first annular pretreatment box is installed in the low-temperature section for low-temperature drying of straw, and the second annular pretreatment box is installed in the high-temperature section for high-temperature drying of poultry manure. The heat radiated outward from the electromagnetic heating rotary carbonization furnace is used as the heat source for pretreatment, which is energy-saving and environmentally friendly.

[0023] 3. By installing a rotary screening mechanism and starting the first motor, the first gear drives the electromagnetic heating rotary carbonization furnace to rotate via the first gear ring. Simultaneously, the second gear ring drives the rotating ring to rotate, which in turn drives the first and second annular pretreatment boxes to rotate synchronously via the connecting rod. Crushed straw and poultry manure are fed through their respective feeding channels and loaded into multiple straw chambers and manure chambers respectively. At the same time, the electric push rod is activated to intermittently extend and retract, synchronously pushing the first and second annular pretreatment boxes to swing up and down. Under the action of rotation and swinging, the internal materials are turned over. Combined with the rotation, the heating is uniform, the drying effect is good, the moisture content of straw and manure is reduced, the subsequent carbonization effect is improved, and energy consumption is reduced.

[0024] 4. By setting up an arc-shaped screen and a straw discharge port, small impurities, such as mud and sand, are screened out through the arc-shaped screen during the up-and-down swing of the first annular pretreatment box. The impurities are discharged from the container through the first arc-shaped discharge hood. After drying, the opening and closing component opens the straw discharge port, and multiple straw chambers are discharged through the straw discharge port in sequence.

[0025] 5. By setting multiple arc-shaped openings and manure particle discharge ports, the second annular pretreatment box can be started to swing after rotating for a period of time. The swinging process breaks up the dried and clump-like manure, which is then ground into fine particles through full contact with multiple grinding balls. The second annular pretreatment box swings up and down through multiple arc-shaped openings. Under the magnetic attraction of the arc-shaped electromagnetic suction plate, metal impurities in the fine granular manure can be collected in the arc-shaped openings through the arc-shaped mesh. The metal impurities in the manure are caused by diet and the breeding environment during the breeding process. Simply start the second motor, which drives the third gear ring to rotate through the second gear, thereby driving the arc-shaped electromagnetic suction plate to rotate and open multiple arc-shaped openings. The metal impurities can then be discharged through the second arc-shaped discharge hood. At the same time, the up and down swinging can screen out the fine granular manure through the annular screen and discharge it through the manure particle discharge port.

[0026] 6. By installing a first arc-shaped discharge hood, a second arc-shaped discharge hood, and an auger conveyor, the dried straw falls into the auger conveyor through the first arc-shaped discharge hood, and the granular manure is collected and falls into the input end of the auger conveyor through the second arc-shaped discharge hood. During the conveying process, it can be mixed with the straw in a certain proportion, which can prevent the manure from clumping during carbonization and improve the carbonization efficiency.

Detailed Implementation

[0038] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Referring to Figures 1-10, an agricultural modular containerized organic solid waste carbonization system includes a container 1 and an electromagnetic heating rotary carbonization furnace 12. The electromagnetic heating rotary carbonization furnace 12 is installed obliquely inside the container 1, with its two ends rotatably connected to the front and rear ends of the container 1, respectively. The front section of the electromagnetic heating rotary carbonization furnace 12 is a low-temperature section, and the rear section is a high-temperature section. A feeding hopper 2 for feeding material into the electromagnetic heating rotary carbonization furnace 12 is installed at the front end of the container 1, and a discharge hood 13 for connecting to the discharge end of the electromagnetic heating rotary carbonization furnace 12 is installed at the rear end of the container 1. The material after mixing straw and manure is poured into the feeding hopper 2, enters the electromagnetic heating rotary carbonization furnace 12 for carbonization, and is finally discharged through the discharge hood 13.

[0040] Furthermore, a first gear ring 20 is fixedly sleeved on the outer wall of the front end of the electromagnetic heating rotary carbonization furnace 12, and a first motor 3 is installed at the front end of the container 1. A first gear 21 that meshes with the first gear ring 20 is fixed at the output end of the first motor 3. When the first motor 3 is started, the first gear 21 drives the electromagnetic heating rotary carbonization furnace 12 to rotate through the first gear ring 20.

[0041] The first annular insulation cover 6 and the second annular insulation cover 11 are both fixedly installed inside the container 1, respectively covering the low-temperature section and the high-temperature section, to achieve the insulation effect and prevent material leakage.

[0042] The first annular pretreatment box 23 and the second annular pretreatment box 24 are respectively built into the first annular heat insulation cover 6 and the second annular heat insulation cover 11. Both have multiple partitions 34 fixed circumferentially inside. The first annular pretreatment box 23 forms multiple straw chambers through the partitions 34 circumferentially, and the second annular pretreatment box 24 forms multiple manure chambers through the partitions 34 circumferentially. Multiple heat-conducting fins 29 are installed circumferentially on the inner side of the first annular pretreatment box 23 and the second annular pretreatment box 24. The heat-conducting fins 29 can better conduct the radiated heat to the first annular pretreatment box 23 and the second annular pretreatment box 24, and the heat conduction is uniform.

[0043] A rotary screening mechanism, installed inside container 1, is used to synchronously drive the first annular pretreatment box 23 and the second annular pretreatment box 24 to rotate and swing back and forth. The rotary screening mechanism includes an annular fixing plate 4 fixedly installed inside the front end of container 1. A rotating ring 19 is rotatably connected inside the annular fixing plate 4. A second gear ring 22 that meshes with the first gear 21 is fixed on the inner side of the rotating ring 19. Multiple electric push rods 5 are installed circumferentially on the rotating ring 19. The telescopic ends of the electric push rods 5 are fixedly connected to the front end of the first annular pretreatment box 23. The first annular pretreatment box 23 and the second annular pretreatment box 24 rotate and swing back and forth. The processing boxes 24 are fixedly connected by multiple connecting rods 9 to achieve synchronous rotation and oscillation. The circumferential side walls of the first annular pretreatment box 23 and the second annular pretreatment box 24 respectively abut against the inner walls of the first annular heat preservation cover 6 and the second annular heat preservation cover 11. The electric push rod 5 is activated to extend and retract intermittently, synchronously pushing the first annular pretreatment box 23 and the second annular pretreatment box 24 to swing up and down. Under the action of rotation and oscillation, the internal materials are turned over. With the rotation, the heating is uniform, the drying effect is good, the moisture content of straw and manure is reduced, the subsequent carbonization effect is improved, and energy consumption is reduced.

[0044] For the power supply and control of the electric actuator 5, a circumferentially distributed conductive base and conductive head can be used. The conductive head makes intermittent contact during rotation, thereby causing the electric actuator 5 to start intermittently.

[0045] The bottom front and rear sides of the first annular heat preservation cover 6 are respectively provided with an arc-shaped screen 25 and a straw discharge port 27. An opening and closing component is installed inside the straw discharge port 27. During the up and down swing of the first annular pretreatment box 23, small impurities such as mud and sand can be screened out through the arc-shaped screen 25 and discharged from the container 1 through the first arc-shaped impurity discharge cover 14. After drying, the opening and closing component opens the straw discharge port 27, and multiple straw chambers are sequentially discharged through the straw discharge port 27.

[0046] The bottom front and rear sides of the second annular heat insulation cover 11 are respectively provided with a metal impurity filter assembly and a fecal particle discharge port 26. The metal impurity filter assembly includes multiple arc-shaped openings 31 equidistantly opened on the bottom front side of the second annular heat insulation cover 11. The top of the arc-shaped openings 31 is provided with an arc-shaped mesh 32 flush with the inner surface of the second annular heat insulation cover 11. The bottom of the second annular heat insulation cover 11 is equipped with an arc-shaped electromagnetic suction plate 33 that opens and closes the multiple arc-shaped openings 31. The inner side of the arc-shaped electromagnetic suction plate 33 is attached to the outer wall of the second annular heat insulation cover 11. An annular screen 30 is installed on the rear side of the second annular pretreatment box 24. Multiple grinding balls 28 are installed in the multiple fecal chambers of the second annular pretreatment box 24. The extreme position of the second annular pretreatment box 24 swinging backward is not closer to the fecal particle discharge port 26. After the second annular pretreatment box 24 rotates and dries for a period of time, it starts to swing. The swinging process breaks up the dried and clump-like fecal matter. After fully contacting the multiple grinding balls 28, it is ground into fine particles. The second annular pretreatment box 24 swings up and down through multiple arc-shaped openings 31. Under the magnetic attraction of the arc-shaped electromagnetic suction plate 33, the metal impurities in the fine granular fecal matter can be collected in the arc-shaped openings 31 through the arc-shaped mesh 32.

[0047] Furthermore, a second motor 7 is installed on the top of the second annular heat insulation cover 11, and a second gear 8 is fixed to the output end of the second motor 7. A third gear ring 10 that meshes with the second gear 8 is fixed to the front side of the second annular heat insulation cover 11. An arc-shaped electromagnetic suction plate 33 is fixedly installed on the side wall of the third gear ring 10. When the second motor 7 is started, the third gear ring 10 is rotated through the second gear 8, which in turn drives the arc-shaped electromagnetic suction plate 33 to rotate, opening multiple arc-shaped openings 31, so that metal impurities can be discharged through the second arc-shaped impurity discharge cover 18.

[0048] In addition, the bottoms of the arc-shaped screen 25 and the multiple arc-shaped openings 31 are respectively covered by a first arc-shaped waste discharge cover 14 and a second arc-shaped waste discharge cover 18. The waste discharge ends of the first arc-shaped waste discharge cover 14 and the second arc-shaped waste discharge cover 18 extend out of the container 1. The bottoms of the straw discharge port 27 and the manure pellet discharge port 26 are respectively covered by a first arc-shaped discharge cover 15 and a second arc-shaped discharge cover 17. An upwardly angled auger conveyor cylinder 16 is fixedly installed at the bottom of the container 1. The first arc-shaped discharge cover 15 and the second arc-shaped discharge cover 17... The feeding ends of both are connected to the auger conveyor cylinder 16, where the conveying and mixing are completed. The discharge end of the auger conveyor cylinder 16 extends out of the front side of the container 1. The dried straw falls into the auger conveyor cylinder 16 through the first arc-shaped feeding hood 15, and the granular manure is collected and falls into the input end of the auger conveyor cylinder 16 through the second arc-shaped feeding hood 17. During the conveying process, it can be mixed with the straw in proportion, which can avoid the clumping of manure during carbonization and improve carbonization efficiency.

[0049] The container 1 also integrates an exhaust gas treatment module and a remote controller. The exhaust gas treatment module is used to treat carbonization exhaust gas, and the remote controller is used to control the speed and temperature of the electromagnetic heating rotary carbonization furnace 12. It supports remote parameter control via the Internet of Things. The containerized integrated form has a short construction period and low cost. The container is easy to transport and is relatively flexible. It is suitable for solid waste treatment scenarios such as rural areas and islands. It can combine the drying, crushing, and screening processes with the carbonization process, and has a high degree of integration.

[0050] The electromagnetic heating rotary carbonization furnace 12 is easy to control in terms of temperature and produces less pollution. The front and rear sections of the electromagnetic heating rotary carbonization furnace 12 are low-temperature and high-temperature sections, respectively. The first annular pretreatment box 23 is installed in the low-temperature section for low-temperature drying of straw, and the second annular pretreatment box 24 is installed in the high-temperature section for high-temperature drying of poultry manure. The heat radiated outward by the electromagnetic heating rotary carbonization furnace 12 is used as the heat source for pretreatment, which is energy-saving and environmentally friendly.

[0051] When the first motor 3 is started, the first gear 21 drives the electromagnetic heating rotary carbonization furnace 12 to rotate through the first gear ring 20. At the same time, it drives the rotating ring 19 to rotate through the second gear ring 22. Then, through the connecting rod 9, it drives the first annular pretreatment box 23 and the second annular pretreatment box 24 to rotate synchronously. The chopped straw and poultry manure are fed through the corresponding feeding channels 35 and loaded into multiple straw chambers and manure chambers respectively. At the same time, the electric push rod 5 is activated to intermittently extend and retract, synchronously pushing the first annular pretreatment box 23 and the second annular pretreatment box 24 to swing up and down. Under the action of rotation and swing, the internal materials are turned over. Combined with the rotation, the heating is uniform, the drying effect is good, the moisture content of straw and manure is reduced, the subsequent carbonization effect is improved, and energy consumption is reduced.

[0052] During the up-and-down swinging process of the first annular pretreatment box 23, small impurities such as mud and sand are screened out through the arc-shaped screen 25 and discharged from the container 1 through the first arc-shaped discharge cover 14. After drying, the opening and closing component opens the straw discharge port 27, and multiple straw chambers are discharged through the straw discharge port 27 in sequence.

[0053] After the second annular pretreatment box 24 rotates for a period of time, it can be started to swing. The swinging process breaks up the dried and clump-like manure, and then it comes into full contact with multiple grinding balls 28 to grind it into fine particles. The second annular pretreatment box 24 swings up and down through multiple arc-shaped openings 31. Under the magnetic attraction of the arc-shaped electromagnetic suction plate 33, the metal impurities in the fine granular manure can be collected in the arc-shaped openings 31 through the arc-shaped mesh 32. The metal impurities in the manure are caused by diet and breeding environment during the breeding process. Just start the second motor 7, drive the third gear ring 10 to rotate through the second gear 8, and then drive the arc-shaped electromagnetic suction plate 33 to rotate, opening multiple arc-shaped openings 31, so that the metal impurities can be discharged through the second arc-shaped discharge cover 18. At the same time, the up and down swinging can screen out the fine granular manure through the annular screen 30 and feed it through the manure particle discharge port 26.

[0054] The dried straw falls into the auger conveyor cylinder 16 through the first arc-shaped discharge hood 15, and the granular manure is collected and falls into the input end of the auger conveyor cylinder 16 through the second arc-shaped discharge hood 17. During the conveying process, it can be mixed with the straw in proportion, which can prevent the manure from clumping during carbonization and improve the carbonization efficiency.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
