Description

Technical Field

[0001] The present invention relates to the field of composting technology, and in particular to a self-propelled, precisely coordinated and controlled intelligent composting reactor. Background Art

[0002] With the continuous expansion of livestock and poultry farming, the amount of livestock and poultry manure produced has increased rapidly. Composting is a common method of converting livestock and poultry manure into organic fertilizer, realizing its resource utilization. Aerobic composting technology, a biodegradable method, decomposes organic waste in livestock and poultry manure through the metabolic activity of microorganisms under aerobic conditions and converts it into stable humus-like substances.

[0003] A composting reactor is a device specifically designed for composting. It typically contains an aerobic zone, and the oxygen concentration in this zone needs to be controlled during the composting process. In related art, a threshold value is set for the oxygen concentration in the aerobic zone. During the composting process, the oxygen concentration in the aerobic zone is detected. Based on the detected oxygen concentration value and the set threshold value, the aeration rate in the aerobic zone is controlled until the detected oxygen concentration in the aerobic zone matches the set threshold value. Although this method achieves regulation of the oxygen concentration in the aerobic zone, the aerobic zone undergoes different fermentation stages, and the set oxygen concentration threshold is a fixed value that differs significantly from the oxygen concentration required for each fermentation stage, resulting in suboptimal fermentation of the compost material. Furthermore, the reactor often operates in a highly aerated state (to maintain an aerobic state), lacking a pretreatment stage for the composting materials. Furthermore, this highly aerated state can cause significant nutrient loss in the later stages of composting (cooling and maturation), hindering the achievement of a high humification level. Furthermore, the high aeration rate used throughout the composting process also leads to high operating costs and energy consumption.

[0004] Therefore, how to solve the problems of unsatisfactory material fermentation effect, low humification degree, large nutrient loss and high energy consumption in composting reactors in related technologies has become an important technical problem to be solved by those skilled in the art.

[0027] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] The following combination Figures 1 to 8 The present invention describes a self-propelled, precisely coordinated, and controlled intelligent composting reactor.

[0029] like Figures 1 to 8 As shown, the self-propelled, precise, coordinated, and controlled intelligent composting reactor provided by the embodiment of the present invention includes a reactor body, an aeration device, an oxygen concentration sensor, a normoxic zone temperature sensor 5, a normoxic zone moisture sensor 23, and a control device 6.

[0030] Specifically, the interior of the reactor body has a low oxygen zone 1, a normoxic zone 2 and an ultra-low oxygen zone 3 distributed in sequence. The low oxygen zone 1 and the ultra-low oxygen zone 3 are both connected to the normoxic zone 2. The material in the low oxygen zone 1 can move to the normoxic zone 2, and the material in the normoxic zone 2 can move to the ultra-low oxygen zone 3.

[0031] On the basis of normoxic zone 2, hypoxic zone 1 and ultra-low oxygen zone 3 are added. Hypoxic zone 1 is the pretreatment stage, which can degrade some complex organic matter or difficult-to-degrade organic matter, provide a large amount of easily degradable small-molecule organic matter, and keep some aerobic microorganisms alive, paving the way for aerobic fermentation, making it heat up faster, and achieving better fermentation results for difficult-to-degrade or complex organic matter. Ultra-low oxygen zone 3 is the cooling and composting stage, mainly because most of the organic matter in the late stage of composting is decomposed and high aeration volume is not required. When micro-aerobic aeration is performed, not only aerobic microorganisms, but also facultative microorganisms and anaerobic microorganisms can survive. Therefore, not only aerobic microorganisms can re-degrade some difficult-to-degrade complex organic matter. Ultra-low oxygen zone 3 can achieve a better level of humification.

[0032] The oxygen concentration sensor includes a low oxygen zone oxygen concentration sensor 17, a normoxia zone oxygen concentration sensor 4 and an ultra-low oxygen zone oxygen concentration sensor 8. The low oxygen zone oxygen concentration sensor 17 is used to detect the oxygen concentration in the material in the low oxygen zone 1, the normoxia zone oxygen concentration sensor 4 is used to detect the oxygen concentration in the material in the normoxia zone 2, and the ultra-low oxygen zone oxygen concentration sensor 8 is used to detect the oxygen concentration in the material in the ultra-low oxygen zone 3.

[0033] The aeration device can aerate the materials in the hypoxic zone 1, the normoxic zone 2 and the ultra-low oxygen zone 3 respectively, so as to provide appropriate amounts of oxygen to the hypoxic zone 1, the normoxic zone 2 and the ultra-low oxygen zone 3 respectively.

[0034] The normoxic zone temperature sensor 5 is used to detect the temperature of the material in the normoxic zone 2 , and the normoxic zone moisture sensor 23 is used to detect the moisture content of the material in the normoxic zone 2 .

[0035] The aeration device, the hypoxic zone oxygen concentration sensor 17, the normoxic zone oxygen concentration sensor 4, the ultra-low oxygen zone oxygen concentration sensor 8, the normoxic zone temperature sensor 5, and the normoxic zone moisture sensor 23 are all electrically connected to the control device 6. The control device 6 can control the aeration condition of each zone by the aeration device according to the oxygen concentration in the material in each zone.

[0036] The temperature and moisture content of the material in the normoxic zone 2 can indirectly reflect the degradation process of organic matter in the normoxic zone 2. When aerating the material in the normoxic zone 2, the current set value of the oxygen concentration in the material in the normoxic zone 2 is determined based on the current temperature and moisture content of the material in the normoxic zone 2. The aeration device is controlled based on the current set value of the oxygen concentration and the current oxygen concentration of the material in the normoxic zone 2.

[0037] With such a configuration, the real-time demand of the normoxic zone 2 for oxygen concentration is determined according to the real-time situation of the normoxic zone 2, and the determined real-time demand of the normoxic zone 2 for oxygen concentration is set in real time as the set value of the oxygen concentration of the normoxic zone 2. Then, the aeration amount of the aeration device is controlled according to the real-time detection value of the normoxic zone oxygen concentration sensor 4 and the real-time set set value of the oxygen concentration of the normoxic zone 2, thereby improving the consistency between the set value of the oxygen concentration of the normoxic zone 2 and the real-time actual demand of the normoxic zone 2 for oxygen concentration, effectively ensuring the fermentation effect of the normoxic zone 2, and solving the problems of unsatisfactory material fermentation effect, low humification degree, large nutrient loss and high energy consumption in the composting reactor in the related art.

[0038] In embodiments of the present invention, the relationship between the current temperature of the material in the normoxic zone 2, the current moisture content of the material in the normoxic zone 2, and the current set value of the oxygen concentration in the material in the normoxic zone 2 is expressed as C1 = a × WC - b × T1 + e. Here, C1 is the current set value of the oxygen concentration in the material in the normoxic zone 2, expressed in percentage (%); WC is the current moisture content of the material in the normoxic zone 2, expressed in percentage (%); and T1 is the current temperature of the material in the normoxic zone 2, expressed in degrees Celsius (°C). a, b, and e are all constants that can be determined through multiple experiments. In some embodiments, a = 3.366, b = 0.198, and e = 22.336 were determined experimentally.

[0039] The current temperature T1 of the material in the normoxic zone 2 is detected by the normoxic zone temperature sensor 5. The current moisture content of the material in the normoxic zone 2 is detected by the normoxic zone moisture sensor 23. Based on the above relationship C1=a×WC-b×T1+e, the current set value C1 of the oxygen concentration in the material in the normoxic zone 2 can be calculated. Simultaneously, the oxygen concentration in the material in the normoxic zone 2 is detected in real time by the normoxic zone oxygen concentration sensor 4. The aeration amount of the aeration device at the current moment is controlled based on the detected oxygen concentration in the material in the normoxic zone 2 and the calculated current set value C1 of the oxygen concentration in the material in the normoxic zone 2.

[0040] Specifically, when controlling the aeration device based on the current set value of the oxygen concentration and the current oxygen concentration of the material in the normoxic zone 2, the current set range of the oxygen concentration can be determined based on the current set value of the oxygen concentration. Then, the aeration device is controlled based on the current set range of the oxygen concentration.

[0041] The oxygen concentration setting value corresponding to each moment is within a numerical range, which is more convenient for control.

[0042] In a specific embodiment, the lower limit of the current setting range can be set to 95% of the current setting value of the oxygen concentration; and the upper limit of the current setting range can be set to 105% of the current setting value of the oxygen concentration.

[0043] When the detected oxygen concentration of the material in the normoxic zone 2 is lower than 95% of the calculated set value of the oxygen concentration of the material in the normoxic zone 2 at the current moment, the aeration device is controlled to increase the aeration volume. When the detected oxygen concentration of the material in the normoxic zone 2 is higher than 105% of the calculated set value of the oxygen concentration of the material in the normoxic zone 2 at the current moment, the aeration device is controlled to reduce the aeration volume or stop aeration. When the detected oxygen concentration of the material in the normoxic zone 2 is higher than 95% of the calculated set value of the oxygen concentration of the material in the normoxic zone 2 at the current moment and lower than 105% of the calculated set value of the oxygen concentration of the material in the normoxic zone 2 at the current moment, the aeration device is controlled to maintain the aeration volume unchanged.

[0044] In the embodiment of the present invention, when controlling the aeration amount of the hypoxic zone 1 and the ultra-low oxygen zone 3 , it is necessary to set an oxygen concentration setting range for the hypoxic zone 1 and the ultra-low oxygen zone 3 , respectively.

[0045] The hypoxic zone oxygen concentration sensor 17 detects the oxygen concentration in the material in the hypoxic zone 1 in real time, and the control device controls the aeration device according to the detected oxygen concentration in the material in the hypoxic zone 1 and the oxygen concentration setting range corresponding to the hypoxic zone 1. When the detected oxygen concentration in the material in the hypoxic zone 1 is lower than the lower limit of the oxygen concentration setting range of the hypoxic zone 1, the aeration device is controlled to increase the aeration amount. When the detected oxygen concentration in the material in the hypoxic zone 1 is higher than the upper limit of the oxygen concentration setting range of the hypoxic zone 1, the aeration device is controlled to reduce the aeration amount or stop aeration. When the detected oxygen concentration in the material in the hypoxic zone 1 is higher than the lower limit of the oxygen concentration setting range of the hypoxic zone 1 and lower than the upper limit of the oxygen concentration setting range of the hypoxic zone 1, the aeration amount of the aeration device is controlled to remain unchanged.

[0046] Similarly, the ultra-low oxygen zone oxygen concentration sensor 8 detects the oxygen concentration of the material in the ultra-low oxygen zone 3 in real time, and the control device controls the aeration device based on the detected oxygen concentration of the material in the ultra-low oxygen zone 3 and the oxygen concentration setting range corresponding to the ultra-low oxygen zone 3. When the detected oxygen concentration of the material in the ultra-low oxygen zone 3 is lower than the lower limit of the oxygen concentration setting range of the ultra-low oxygen zone 3, the aeration device is controlled to increase the aeration volume. When the detected oxygen concentration of the material in the ultra-low oxygen zone 3 is higher than the upper limit of the oxygen concentration setting range of the ultra-low oxygen zone 3, the aeration device is controlled to reduce the aeration volume or stop aeration. When the detected oxygen concentration of the material in the ultra-low oxygen zone 3 is higher than the lower limit of the oxygen concentration setting range of the ultra-low oxygen zone 3 and lower than the upper limit of the oxygen concentration setting range of the ultra-low oxygen zone 3, the aeration volume of the aeration device is controlled to remain unchanged.

[0047] In a specific embodiment, the oxygen concentration in the material in the low oxygen zone 1 can be set in the range of 3% to 5%, and the oxygen concentration in the material in the ultra-low oxygen zone 3 can be set in the range of 1% to 3%.

[0048] In the embodiment of the present invention, the aeration device includes an aerator 10 , an aeration pipeline and a first connecting pipeline 11 .

[0049] An aerator 10 is located outside the reactor body. An aeration line is located inside the reactor body, at its bottom. The sidewalls of the aeration line are provided with spaced aeration holes. A first connecting line 11 is located outside the reactor body, connecting the aeration line to the aerator 10.

[0050] When the aerator 10 is in operation, it can deliver air or oxygen or other gases into the aeration pipeline and then deliver them into the reactor body through the aeration holes, thereby replenishing oxygen for the normoxic zone 2. Placing the aeration pipeline at the bottom of the reactor body can promote the uniform distribution of oxygen throughout the material in the normoxic zone 2, significantly improving the ventilation efficiency of the normoxic zone 2.

[0051] In this embodiment, the reactor body includes a box body 12, a partition plate assembly and a partition assembly.

[0052] The interior of the box body 12 has a receiving space. The partition plate assembly is arranged at the bottom of the box body 12. There is a distance between the partition plate assembly and the bottom wall of the box body 12 to form an aeration chamber.

[0053] The partition plate assembly is provided with multiple, spaced-apart communication holes. These holes allow only air from the aeration chamber to flow upward from the partition plate assembly, while preventing moisture from flowing upward from the partition plate assembly. This can be achieved by controlling the diameter of the communication holes, which can be set within a range of 2 to 10 mm.

[0054] To prevent accidental leakage of water from above the partition plate assembly into the aeration chamber, a cleaning hole with controllable opening and closing can be provided at a position corresponding to the aeration chamber on the side wall of the housing 12 to facilitate regular cleaning of the aeration chamber. Each aeration chamber has a corresponding cleaning hole.

[0055] The partition assembly is arranged in the aeration chamber, and the partition assembly divides the aeration chamber into a microaerobic aeration chamber 14, an aerobic aeration chamber 15 and a hypoxic aeration chamber 16. The microaerobic aeration chamber 14 is located below the hypoxic zone 1, the aerobic aeration chamber 15 is located below the normoxic zone 2, and the hypoxic aeration chamber 16 is located below the ultra-low oxygen zone 3.

[0056] Specifically, the partition plate assembly includes a hypoxic zone partition plate 7, a normoxic zone partition plate 9, and an ultra-low oxygen zone partition plate 13. The hypoxic zone partition plate 7 is located above the microaerobic aeration chamber 14 and is detachably connected to the housing 12. The normoxic zone partition plate 9 is located above the aerobic aeration chamber 15 and is detachably connected to the housing 12. The ultra-low oxygen zone partition plate 13 is located above the hypoxic aeration chamber 16 and is detachably connected to the housing 12.

[0057] In this way, the partition plate assembly is divided into blocks and detachably connected to the box body 12 , so as to facilitate cleaning of any one of the micro-aerobic aeration chamber 14 , the aerobic aeration chamber 15 and the hypoxic aeration chamber 16 .

[0058] In a specific embodiment, the diameter of the communicating holes on the hypoxic zone partition plate 7 is set to 2-5 mm, and the porosity of the hypoxic zone partition plate 7 is controlled within a range of 10%-20%. The diameter of the communicating holes on the normoxic zone partition plate 9 is set to 5-10 mm, and the porosity of the normoxic zone partition plate 9 is controlled within a range of 20%-50%. The diameter of the communicating holes on the ultra-low oxygen zone partition plate 13 is set to 2-5 mm, and the porosity of the ultra-low oxygen zone partition plate 13 is controlled within a range of 10%-20%.

[0059] The aeration pipeline includes a first aeration pipeline 18, a second aeration pipeline 19, and a third aeration pipeline 20. The first aeration pipeline 18 is located in the microaerobic aeration chamber 14, the second aeration pipeline 19 is located in the aerobic aeration chamber 15, and the third aeration pipeline 20 is located in the hypoxic aeration chamber 16. This allows the gas to enter the corresponding aeration chamber and be evenly distributed therein before flowing through the connecting holes to the reaction zone. This increases the aeration area of the aeration device in each reaction zone, resulting in more uniform aeration. Furthermore, direct contact between the aeration pipeline and the material is avoided, which helps extend the service life of the aeration pipeline.

[0060] The first connecting pipeline 11 has three branch pipelines, which are respectively connected to the first aeration pipeline 18, the second aeration pipeline 19, and the third aeration pipeline 20. Each of the three branch pipelines is provided with a first control valve 21 and a flow meter 22. The first control valve 21 can control the on / off state of the branch pipeline and adjust the flow rate within the branch pipeline.

[0061] The flow meter 22 and the first control valve 21 are both electrically connected to the control device 6. The control device 6 can control the aeration amount of each zone individually according to the oxygen demand in the hypoxic zone 1, the normoxic zone 2 and the ultra-hypoxic zone 3.

[0062] The partition assembly includes a partition bar 39. The hypoxic zone 1, the normoxic zone 2 and the ultra-low oxygen zone 3 are distributed along the longitudinal direction of the reactor body. The partition bar 39 extends along the transverse direction of the reactor body. The partition bar 39 is sealed and connected to the bottom wall of the box body 12, the side wall of the box body 12 and the partition plate assembly, so that the microaerobic aeration chamber 14, the aerobic aeration chamber 15 and the hypoxic aeration chamber 16 are independent of each other to avoid mutual influence.

[0063] A support block 40 is further provided between the partition plate assembly and the bottom wall of the box body 12 for supporting the partition plate assembly to improve the rigidity of the partition plate assembly. A plurality of support blocks 40 are provided, and the plurality of support blocks 40 are distributed at intervals.

[0064] The partition plate assembly can be detachably connected to the box body 12, the partition bar 39, and the support block 40 to facilitate subsequent maintenance.

[0065] In an embodiment of the present invention, a stirring device is provided inside the reactor body, and a lifting mechanism is provided between the hypoxic region oxygen concentration sensor 17 and the top wall of the reactor body, between the normoxic region oxygen concentration sensor 4 and the top wall of the reactor body, between the ultra-low oxygen region oxygen concentration sensor 8 and the top wall of the reactor body, between the normoxic region temperature sensor 5 and the top wall of the reactor body, and between the normoxic region moisture sensor 23 and the top wall of the reactor body. The lifting mechanism can drive any one of the hypoxic region oxygen concentration sensor 17, the normoxic region oxygen concentration sensor 4, the ultra-low oxygen region oxygen concentration sensor 8, the normoxic region temperature sensor 5, and the normoxic region moisture sensor 23 to rise or fall, thereby adjusting the height of any one of the hypoxic region oxygen concentration sensor 17, the normoxic region oxygen concentration sensor 4, the ultra-low oxygen region oxygen concentration sensor 8, the normoxic region temperature sensor 5, and the normoxic region moisture sensor 23.

[0066] The stirring device and the lifting mechanism are both electrically connected to the control device 6. The control device 6 can control the low oxygen zone oxygen concentration sensor 17, the normoxia zone oxygen concentration sensor 4, the ultra-low oxygen zone oxygen concentration sensor 8, the normoxia zone temperature sensor 5, and the normoxia zone moisture sensor 23 to rise to the top of the reactor body when the stirring device is running, and control the low oxygen zone oxygen concentration sensor 17, the normoxia zone oxygen concentration sensor 4, the ultra-low oxygen zone oxygen concentration sensor 8, the normoxia zone temperature sensor 5, and the normoxia zone moisture sensor 23 to descend to immerse the material when the stirring device stops running.

[0067] In this embodiment, the stirring device includes a support base 24 , a first driving mechanism, a mounting base 25 , a second driving mechanism, a spiral stirring mechanism 26 and a scraper 28 .

[0068] The support base 24 can move relative to the reactor body along the longitudinal direction of the reactor body, and the first driving mechanism is used to drive the support base 24 to move along the longitudinal direction of the reactor body.

[0069] The mounting seat 25 is disposed on the supporting seat 24 , and the supporting seat 24 can drive the mounting seat 25 to move along the longitudinal direction of the reactor body.

[0070] The mounting base 25 can move laterally along the reactor body relative to the supporting base 24. The second driving mechanism is used to drive the mounting base 25 to move laterally along the reactor body.

[0071] The spiral stirring mechanism 26 is disposed on the mounting seat 25 , and the mounting seat 25 can drive the spiral stirring mechanism 26 to move longitudinally along the reactor body, and can also drive the spiral stirring mechanism 26 to move transversely along the reactor body.

[0072] The spiral stirring shaft 27 of the spiral stirring mechanism 26 is capable of rotating about its own axis relative to the mounting base 25. The rotation of the spiral stirring shaft 27 agitates the material. The spiral stirring shaft 27 is tilted relative to the bottom wall of the reactor body. By controlling the rotation direction of the spiral stirring shaft 27, the material can be moved from the low oxygen zone 1 to the ultra-low oxygen zone 3, thereby achieving continuous composting.

[0073] The spiral stirring mechanism 26 has the functions of stirring and longitudinal conveying at the same time, and there is no need to set up an additional longitudinal conveying device for the material, which is beneficial to simplifying the structure of the reactor, reducing the floor space and reducing energy consumption.

[0074] The scraper 28 is located below the spiral stirring shaft 27 and is fixed relative to the mounting base 25. The scraper 28 is used to scrape the materials on the bottom wall of the low oxygen zone 1, the bottom wall of the normoxia zone 2 and the bottom wall of the ultra-low oxygen zone 3 when the mounting base 25 moves along the longitudinal direction of the reactor body, so as to reduce the accumulation of materials at the bottom of the reactor body and improve the transportation efficiency.

[0075] The scraper 28 interacts with the partition plate assembly, and arranging the aeration pipe below the partition plate assembly can avoid interference of the aeration pipe with the scraper 28, avoid wear on the aeration pipe, improve durability, and extend service life.

[0076] Specifically, the spiral stirring shaft 27 can be set as a hollow shaft, and the scraper 28 has a connecting shaft. The connecting shaft is passed through the interior of the hollow shaft, and the connecting shaft is fixedly connected to the mounting seat 25.

[0077] The first driving mechanism, the second driving mechanism and the spiral stirring mechanism 26 are all electrically connected to the control device 6. The control device 6 can control the position and start and stop of the spiral stirring mechanism 26 as needed to achieve automatic control.

[0078] In a specific embodiment, the height of the spiral stirring shaft 27 at one end closer to the ultra-low oxygen zone 3 is greater than that at the other end, and the end wall of the housing 12 at the end where the discharge port is located is also inclined, with the inclination angle of the end wall of the housing 12 at the end where the discharge port is located being consistent with the inclination angle of the spiral stirring shaft 27. By placing the spiral stirring shaft 27 closer to the end wall of the housing 12 at the end where the discharge port is located, the rotation of the spiral stirring shaft 27 can transport the material in the ultra-low oxygen zone 3 to the discharge port, allowing the material to be discharged from the discharge port.

[0079] The inclination angle of the spiral stirring shaft 27 can be controlled within a range of 10° to 20°. Specifically, the inclination angle of the spiral stirring shaft 27 can be set to 15°.

[0080] It should be noted that a sealing plate is provided at the discharge port, which closes the discharge port in its natural state. When the spiral stirring shaft 27 delivers the material to the discharge port, the material exerts an extrusion force on the sealing plate, thereby causing the sealing plate to rotate to open the discharge port.

[0081] In this embodiment, the stirring device also includes a stirring oxygen concentration sensor, which is arranged on the spiral stirring mechanism 26. The stirring oxygen concentration sensor is used to detect the oxygen concentration in the material around the spiral stirring mechanism 26 in real time when the stirring device is running, so as to determine the area where the spiral stirring mechanism 26 is located based on the detected oxygen concentration in the material around the spiral stirring mechanism 26, and then control the rotation speed of the spiral stirring mechanism 26.

[0082] The spiral stirring mechanism has different rotational speeds for different areas of the hypoxic zone 1, normoxic zone 2, and ultra-hypoxic zone 3. When the spiral stirring mechanism 26 is in the hypoxic zone 1, it is controlled to rotate at 10 to 20 revolutions per minute; when the spiral stirring mechanism 26 is in the normoxic zone 2, it is controlled to rotate at 20 to 30 revolutions per minute; and when the spiral stirring mechanism 26 is in the ultra-hypoxic zone 3, it is controlled to rotate at 5 to 10 revolutions per minute.

[0083] During operation, the self-propelled, precisely coordinated, and controlled intelligent composting reactor provided by the present invention operates by running the spiral stirring mechanism 26 once from the feed port to the discharge port of the reactor body, thereby moving the material within the reactor body from the low oxygen zone to the ultra-low oxygen zone. Specifically, the spiral stirring mechanism 26 can be operated once per day.

[0084] In this embodiment, first support and guide mechanisms are respectively provided between the two transverse ends of the support seat 24 and the reactor body. The first support and guide mechanisms include a first guide groove 29 and a first roller 30 .

[0085] A first guide groove 29 is provided in the reactor body, extending longitudinally along the reactor body. A first roller 30 is rotatably provided on the support base 24. The first roller 30 is disposed transversely to the reactor body relative to the rolling axis of the support base 24 and is capable of rolling within the first guide groove 29. The interaction between the first roller 30 and the first guide groove 29 provides a guide for the sliding movement of the support base 24.

[0086] The first driving mechanism includes a first rack 31 , a first gear 32 and a first driving member 37 .

[0087] A first rack 31 is mounted on the reactor body and extends longitudinally along the reactor body. A first gear 32 meshes with the first rack 31 and is rotatably mounted on the support base 24, with the axis of the first gear 32 extending vertically along the reactor body. A first drive member 37 is mounted on the support base 24 and is in driving connection with the first gear 32. The first drive member 37 is electrically connected to the control device 6.

[0088] The bottom wall of the first guide groove 29 supports the first roller 30 and is capable of bearing load, thereby avoiding the influence of gravity and the like on the first gear 32 and the first rack 31. The meshing transmission of the first gear 32 and the first rack 31 is not affected by the gravity of components such as the support base 24, the mounting base 25, and the spiral stirring mechanism 26, thereby reducing the load on the first rack 31 and the first driving member 37, which is conducive to the miniaturization of the first driving member 37, reducing the mass of the first driving member 37, further reducing the load on the support base 24, reducing energy consumption, and reducing the deformation of the support base 24 and the first rack 31.

[0089] Similarly, a second support and guide mechanism is provided between the two longitudinal ends of the mounting seat 25 and the support seat 24 . The second support and guide mechanism includes a second guide groove 33 and a second roller 34 .

[0090] A second guide groove 33 is provided on the support base 24, extending transversely along the reactor body. A second roller 34 is rotatably mounted on the mounting base 25, with its rolling axis positioned longitudinally along the reactor body relative to the mounting base 25. The second roller 34 is capable of rolling within the second guide groove 33. The interaction between the second roller 34 and the second guide groove 33 provides a guide for the sliding movement of the mounting base 25.

[0091] The second driving mechanism includes a second rack 35 , a second gear 36 and a second driving member 38 .

[0092] A second rack 35 is mounted on the support base 24 and extends transversely along the reactor body. A second gear 36 meshes with the second rack 35 and is rotatably mounted on the mounting base 25, with the axis of the second gear 36 extending vertically along the reactor body. A second drive member 38 is mounted on the mounting base 25 and is in driving connection with the second gear 36. The second drive member 38 is electrically connected to the control device 6.

[0093] The bottom wall of the second guide groove 33 supports the second roller 34 and is capable of bearing loads, thereby avoiding the influence of gravity and the like on the second gear 36 and the second rack 35. The meshing transmission of the second gear 36 and the second rack 35 is not affected by the gravity of components such as the mounting base 25 and the spiral stirring mechanism 26, thereby reducing the load on the second rack 35 and the second driving member 38, which is conducive to the miniaturization of the second driving member 38, reducing the mass of the second driving member 38, further reducing the load on the mounting base 25, reducing energy consumption, and reducing the deformation of the mounting base 25 and the second rack 35.

[0094] In an embodiment of the present invention, the self-propelled, precisely coordinated and controlled intelligent composting reactor further includes a feeding device, which is used to add materials to the feeding port of the reactor body.

[0095] The loading device includes a guide bracket 42, a connecting bracket 43, a feeding device 41 and a third driving mechanism.

[0096] The guide bracket 42 includes a vertical bracket and an arc bracket. The vertical bracket extends vertically along the reactor body. The first end of the arc bracket is tangentially connected to the upper end of the vertical bracket. The second end of the arc bracket is connected to the reactor body, and the tangent line of the second end of the arc bracket is parallel to the longitudinal direction of the reactor body. Figure 8 .

[0097] The connecting bracket 43 can slide back and forth along the guiding bracket 42 . The third driving mechanism is used to drive the connecting bracket 43 to slide back and forth relative to the guiding bracket 42 . The third driving mechanism is electrically connected to the control device 6 .

[0098] The material conveying device 41 is used to transport materials between the material source and the reactor body. The material conveying device 41 can be, but is not limited to, a trolley.

[0099] The feed device 41 is detachably connected to the connecting bracket 43. Once disconnected, the feed device 41 can reciprocate between the reactor body and the material source to transport the material. Once the feed device 41 is transporting material to the reactor body, the feed device 41 is connected to the connecting bracket 43, and the third drive mechanism is activated to drive the feed device 41 upward along the guide bracket 42, gradually approaching the reactor body's feed port.

[0100] One end of the conveying device 41 is open. When the connecting bracket 43 is positioned on the vertical support, the opening of the conveying device 41 faces upward. Similarly, when the connecting bracket 43 is positioned on the second end of the curved support, the plane of the conveying device 41's opening is perpendicular to the longitudinal direction of the reactor body. In this case, the material in the conveying device 41 can be discharged automatically.

[0101] A sealing plate is provided at the feeding port, which seals the feeding port in a natural state. When the material in the feeding device 41 is discharged, the material exerts a squeezing force on the sealing plate, thereby enabling the sealing plate to rotate to open the feeding port.

[0102] To achieve a detachable connection between the connecting bracket 43 and the feeder 41, slots can be provided on opposite sides of the feeder 41. A pair of forked arms can be provided on the connecting bracket 43, which can be inserted into the slots. When the forked arms are inserted into the slots, the feeder 41 and the connecting bracket 43 are connected, and the connecting bracket 43 can drive the feeder 41 up and down. To detach the feeder 41 from the connecting bracket 43, the forked arms can be removed from the slots.

[0103] The third drive mechanism includes a sprocket 44, a chain 45, and a third drive member. The sprocket 44 is mounted on the upper end of the guide bracket 42, and the third drive member is capable of driving the sprocket 44 to rotate. The chain 45 is wound around the sprocket 44, with a first end connected to the connecting bracket 43 and a second end suspended in the air. The third drive member drives the sprocket 44 to rotate, thereby raising and lowering the first end of the chain 45, thereby raising and lowering the connecting bracket 43.

[0104] In order to ensure the stability and reliability of the third driving mechanism and prevent the chain 45 from being separated from the sprocket 44 , a counterweight may be provided at the second end of the chain 45 to ensure reliable engagement of the chain 45 with the sprocket 44 .

[0105] The first driving member 37 , the second driving member 38 and the third driving member may be, but are not limited to, motors. When motors are selected, they may be equipped with speed reducers.

[0106] In summary, the self-propelled, precisely coordinated, and intelligent composting reactor provided by the present invention achieves real-time automated control of aeration and stirring, reducing operator skill requirements and labor intensity, improving composting efficiency, ensuring compost product quality, and reducing operational energy consumption. Furthermore, it can be equipped with fault diagnosis and alarm functions to promptly detect and alert operators of operational anomalies.

[0107] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
