Description

Technical Field

[0001] This invention relates to the field of animal husbandry technology, specifically to a deep-trough in-situ fermentation bed system for converting manure into organic fertilizer. Background Technology

[0002] The in-situ fermentation bed system is an innovative technology for treating livestock and poultry manure, designed to convert manure generated during livestock and poultry farming into organic fertilizer. This system involves setting up a fermentation bed outside the livestock and poultry shed, evenly spraying the daily collected manure (such as pig manure and urine) onto the bedding material inside the fermentation tank. High-temperature aerobic fermentation is then carried out using microorganisms, achieving the harmless treatment and resource utilization of the manure. This technology not only solves the environmental pollution problems caused by improper treatment and indiscriminate discharge of livestock and poultry manure, but also achieves effective resource recovery and utilization through the production of organic fertilizer.

[0003] However, despite the numerous advantages of in-situ fermentation bed systems, existing technologies still have some significant shortcomings in practical applications. Firstly, current livestock and poultry farming generally faces the problem of insufficient matching of manure treatment facilities and equipment, resulting in low manure treatment efficiency and an inability to meet the needs of expanding farming scale under limited land use conditions. Existing in-situ fermentation bed technologies have limited manure treatment capacity and poor treatment effects. For example, the patent with authorization announcement number "CN 206909383U" describes an in-situ fermentation bed height of <1.2m and a bedding thickness of only 60-70cm, which is significantly insufficient in terms of manure treatment volume. This severely affects the manure treatment volume effect and the expansion of farming scale. Limited ventilation and oxygenation conditions inside the fermentation bed lead to poor fermentation effects and a tendency for bed stagnation. Furthermore, existing technologies also suffer from insufficient ventilation and oxygenation, and the lack of wastewater return systems. Insufficient ventilation and oxygenation result in insufficient oxygen supply inside the fermentation bed, affecting the fermentation of microorganisms and thus reducing manure treatment efficiency. The lack of wastewater return systems leads to excessive humidity in the fermentation bed, further affecting the fermentation effect. These problems not only limit the application effectiveness of off-site fermentation bed systems, but may also lead to incomplete manure treatment and even secondary pollution. Furthermore, the limited capacity for manure treatment restricts the scale of livestock farming, severely impacting the income-generating capacity of the livestock industry.

[0004] In summary, while ex-situ fermentation bed systems offer significant advantages in environmental protection and resource utilization, some technical shortcomings remain in practical applications. Further optimization of the system design is needed to address these issues. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a deep-trough in-situ fermentation bed system for converting manure into organic fertilizer. This system improves the volume and efficiency of manure treatment, enhances ventilation and oxygenation, and incorporates a wastewater recirculation system to ensure maximum manure treatment effectiveness and resource utilization, thereby promoting the development of the livestock industry.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a deep-trough in-situ fermentation bed system for converting manure into organic fertilizer, comprising a fermentation shed and a fermentation bed, wherein the fermentation bed is located inside the fermentation shed and is used to collect and contain a mixture of livestock and poultry manure and bedding material, and further comprising a control system, monitoring instruments and processing equipment that are interconnected by signals, wherein the processing equipment is used to process the manure in the fermentation bed, the monitoring instruments are used to collect environmental conditions inside the fermentation bed and transmit them to the control system, and the control system is used to issue information warnings and notifications based on the monitoring data collected by the monitoring instruments and to control the processing equipment to process the manure in the fermentation bed;

[0007] The processing equipment includes a transmission unit, a turning unit, an aeration unit, a feeding unit, and a spraying unit. The monitoring instruments include temperature and humidity sensors, flow sensors, cameras, and gas sensors. The control system includes a receiving module, a control module, a data comparison module, a display module, a recording module, and an early warning module.

[0008] The receiving module is used to receive data from the monitoring instrument and transmit the data to the data comparison module for processing and analysis.

[0009] The data comparison module is used to compare the received data with a preset threshold or standard. If the monitored data is normal, no response is made and the operation is carried out according to the initially set operating cycle. If the monitored data is abnormal, it is transmitted to the control module for processing. If the monitored data exceeds the preset range, the data comparison module will transmit it to the early warning module.

[0010] The control module is used to control the operation of the processing equipment according to the initially set operating cycle. The control module is also used to receive abnormal monitoring data from the data comparison module, control the environmental conditions of the fermentation bed, and control the processing equipment until the monitoring data transmitted by the monitoring instrument returns to normal, and then operate according to the initially set operating cycle.

[0011] The recording module is used to record the number of times the turning unit turns, the spraying volume of the spraying unit, the feeding volume of the feeding unit, and the temperature and humidity of the fermentation house and fermentation bed;

[0012] The display module is used to present information such as the system's operating status, monitoring data, control commands, and recorded data to the user in a graphical or textual manner;

[0013] The early warning module is used to receive data that exceeds the preset range from the data comparison module and transmit it to the user through sound alarm, light flashing or remote information. The early warning module is also used to record historical data of abnormal events so that users can conduct subsequent analysis and improvement.

[0014] Furthermore, the transmission unit is used to transport manure generated in livestock and poultry houses to the fermentation bed.

[0015] Furthermore, the turning unit includes a turning machine, which is slidably connected to the side wall of the fermentation bed. The turning machine is used to mix and stir the bedding material and manure. The turning depth of the turning machine is greater than 1.5m, and the turning machine is 10-15cm off the ground.

[0016] Furthermore, the aeration unit is used to analyze the concentrations of oxygen, carbon dioxide, ammonia, hydrogen sulfide, and particulate matter in the fermentation chamber according to the data analysis module, and to aerate the fermentation bed through the control module to promote the uniform distribution of materials and full contact with oxygen. The aeration device includes interconnected vortex air pumps and aeration pipes. The vortex air pumps are fixedly connected in the fermentation chamber, and an aeration ditch is opened at the bottom of the fermentation chamber, with the aeration pipes fixedly connected in the aeration ditch.

[0017] Furthermore, the spraying unit is used to add manure and moisture to the bedding material in the spray fermentation bed. The spraying unit includes a temporary storage tank and several spray pipes. The temporary storage tank is located on one side of the fermentation bed. A sewage pump is installed in the temporary storage tank. The output end of the sewage pump is connected to the input end of the spray pipe. All spray pipes are fixedly connected to the top of the fermentation house. The output end of each spray pipe is connected to a nozzle, and the nozzle is fixedly connected to the turning machine.

[0018] Furthermore, the feeding unit is used to analyze the temperature and humidity of the bedding material according to the data analysis module, and to add microorganisms to the fermentation bed through the control module. The feeding unit includes a bedding box fixedly connected to one side of the turning machine, and a sprinkling pipe is connected to the bedding box. The sprinkling pipe is fixedly connected to the connecting rod of the turning machine.

[0019] Furthermore, cameras are used to monitor and record the on-site operation of the off-site fermentation bed, supplementing situations where monitoring sensors have data but no video or monitoring equipment malfunctions and cannot detect effective data, thus helping farms to make auxiliary judgments on the operational effectiveness of the off-site fermentation bed.

[0020] Furthermore, temperature and humidity sensors are used to monitor the temperature and humidity of the fermentation chamber, fermentation bed, and bedding pile, and transmit the data to the receiving module.

[0021] Furthermore, flow sensors are used to monitor and collect the amount of manure treated, and the manure treatment capacity of the off-site fermentation bed is calculated cumulatively over time periods based on time parameters.

[0022] Furthermore, the gas sensor is used to monitor the concentrations of oxygen, carbon dioxide, ammonia, hydrogen sulfide, and particulate matter in the fermentation bed and fermentation chamber, and transmits the data to the receiving module.

[0023] The above approach has the following beneficial effects:

[0024] 1. This solution, through the optimized design of the fermentation bed structure, as well as the efficient transmission unit, turning unit, aeration unit, feeding unit and spraying unit, enables the system to accommodate and efficiently process large amounts of livestock and poultry manure, significantly improving the volume and efficiency of manure treatment, and providing strong technical support for the expansion of livestock and poultry breeding and the utilization of manure treatment.

[0025] 2. In this solution, the aeration unit is set up to intelligently adjust the aeration rate based on real-time monitoring data of oxygen, carbon dioxide, ammonia, hydrogen sulfide, and particulate matter in the fermentation chamber. This ensures that the materials inside the fermentation bed are in full contact with oxygen, promotes the activity and reproduction of microorganisms, thereby improving fermentation efficiency and quality, and avoiding the problem of poor fermentation effect caused by insufficient oxygen.

[0026] 3. The design of the spray unit in this scheme not only increases the appropriate amount of manure and moisture in the bedding material of the fermentation bed, but also realizes the effective return and reuse of wastewater through the connection between the temporary storage tank and the spray pipe, reducing the waste of water resources. At the same time, it helps to maintain the humidity balance in the fermentation bed and improve the fermentation effect.

[0027] 4. This solution integrates a control system, monitoring instruments, and processing equipment, enabling real-time monitoring and intelligent control of the environment within the fermentation bed. The data comparison module promptly detects and processes abnormal data, while the control module automatically adjusts the operating status of the processing equipment based on data analysis results, ensuring a stable and efficient fermentation process. Through refined management and control, it not only effectively reduces environmental pollution from manure but also transforms manure into high-quality organic fertilizer, maximizing resource utilization and promoting the development of circular agriculture.

[0028] 5. This solution, through the design of recording and display modules, allows users to easily view the system's operating status, monitoring data, control commands, and historical records, greatly facilitating system maintenance and management. Simultaneously, the early warning module can promptly notify users in case of abnormal situations, avoiding potential risks and enhancing system reliability. The camera setup not only provides effective on-site images when monitoring sensor malfunctions but also helps farmers intuitively understand the fermentation bed's operating status, providing crucial visual information for assessing fermentation effectiveness.

[0029] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0037] Example:

[0038] As attached Figure 1 and Figure 2As shown: A deep-trough in-situ fermentation bed system for converting manure into organic fertilizer includes a fermentation shed 1 and a fermentation bed 3. The fermentation bed 3 is located inside the fermentation shed 1 and is used to collect and contain a mixture of livestock and poultry manure and bedding material. It also includes a control system, monitoring instruments, and treatment equipment that are interconnected. The treatment equipment is used to treat the manure in the fermentation bed 3.

If the monitored data is normal, no response is made and the system operates according to the initially set operating cycle. If the monitored data is abnormal, it is transmitted to the control module for processing. If the monitored data exceeds the preset range, the data comparison module will transmit it to the early warning module.

[0042] The control module is used to control the operation of the processing equipment according to the initially set operating cycle. The control module is also used to receive abnormal monitoring data from the data comparison module and control the environmental conditions of the fermentation bed 3 until the monitoring data transmitted by the monitoring instrument returns to normal, and then operate according to the initially set operating cycle.

[0043] The recording module is used to record the number of times the turning unit turns, the amount of spraying by the spraying unit, the amount of feeding by the feeding unit, and the temperature and humidity of fermentation chamber 1 and fermentation bed 3.

[0044] The display module is used to present information such as the system's operating status, monitoring data, control commands, and recorded data to the user in a graphical or textual manner.

[0045] The early warning module is used to receive data that exceeds the preset range from the data comparison module and transmit it to the user through sound alarm, light flashing or remote information. The early warning module is also used to record historical data of abnormal events so that users can conduct subsequent analysis and improvement.

[0046] The transmission unit is used to transport manure from livestock and poultry houses to fermentation bed 3.

[0047] The turning unit includes a turning machine 2, which is slidably connected to the side wall of the fermentation bed 3. The turning machine 2 is used to mix and stir the bedding material and manure. The turning depth of the turning machine 2 is greater than 1.5m, and the turning machine 2 is 10-15cm off the ground.

[0048] The aeration unit is used to analyze the concentration of oxygen, carbon dioxide, ammonia, hydrogen sulfide and particulate matter in fermentation chamber 1 according to the data analysis module, and to aerate fermentation bed 3 through the control module to promote the uniform distribution of materials and full contact with oxygen. The aeration device includes a vortex air pump and aeration pipes that are connected to each other. The vortex air pump is fixedly connected to fermentation chamber 1. An aeration ditch is opened at the bottom of fermentation chamber 1, and the aeration pipe is fixedly connected to the aeration ditch.

[0049] The spray unit is used to add manure and moisture to the bedding material in the spray fermentation bed 3. The spray unit includes a temporary storage tank and several spray pipes. The temporary storage tank is located on one side of the fermentation bed 3. A sewage pump is installed in the temporary storage tank. The output end of the sewage pump is connected to the input end of the spray pipe. All spray pipes are fixedly connected to the top of the fermentation house 1. The output end of the spray pipes is connected to a nozzle. All nozzles are fixedly connected to the turning machine 2.

[0050] The feeding unit is used to analyze the temperature and humidity of the bedding material according to the data analysis module, and add microorganisms to the fermentation bed 3 through the control module. The feeding unit includes a bedding box fixedly connected to one side of the turning machine 2, and a sprinkling pipe is connected to the bedding box. The sprinkling pipe is fixedly connected to the connecting rod of the turning machine 2.

[0051] The camera is used to monitor and record the on-site operation of the off-site fermentation bed 3, in order to make up for the situation where the monitoring sensor has data but no picture or the monitoring equipment is malfunctioning and cannot monitor effective data, and to help the farm to make auxiliary judgments on the operation effect of the off-site fermentation bed 3.

[0052] Temperature and humidity sensors are used to monitor the temperature and humidity of fermentation chamber 1, fermentation bed 3, and bedding pile, and transmit the data to the receiving module.

[0053] The flow sensor is used to monitor and collect the amount of manure treated, and the manure treatment capacity of the off-site fermentation bed 3 is calculated cumulatively over time periods based on time parameters.

[0054] The gas sensor is used to monitor the concentrations of oxygen, carbon dioxide, ammonia, hydrogen sulfide and particulate matter in fermentation bed 3 and fermentation chamber 1, and transmits the data to the receiving module.

[0055] The specific implementation process is as follows: First, level the ground of fermentation bed 3, ensuring a height difference of no more than 5 cm between the front and back. It is also crucial to prevent rainwater from entering fermentation bed 3 during rainy days. Construct drainage ditches to ensure smooth drainage. Fermentation shed 1 should ideally be a closed rectangular structure, with the building area determined based on the breeding volume and site size. The structural framework of fermentation shed 1 should preferably be made of reinforced concrete, with a roof covered with transparent translucent tiles. This design fully utilizes solar energy, which is beneficial for the fermentation of the fermenting materials. The walls of fermentation shed 1 should be reinforced concrete, 20-25cm thick, and perpendicular to the horizontal plane. After completion, the walls should reach a height of 2-2.5m. A 25cm high concrete ring beam should be constructed at the top of the walls. To ensure the turning machine 2 is not easily worn, the top of the ring beam should be smooth and flat. To prevent the turning machine 2 from derailing, the internal width of the wall should be uniform, reaching 5-10 meters. The area of ​​fermentation bed 3 should be designed according to the maximum number of piglets that can be introduced into the pigsty, calculated based on a minimum requirement of 0.25 square meters per piglet (preferably 0.3 square meters per piglet or more). A door should be left on the narrower side of fermentation shed 1 near the road, with a pre-reserved opening for future cleaning and transportation of bedding material. The bottom thickness of fermentation bed 3 should exceed 20cm, and a wastewater return ditch should be provided. The return ditch should be 20cm wide and 15cm deep, filled with gravel and covered with ceramic tiles to prevent fermentation material from entering. The return ditch should be connected to the temporary storage tank via a pipe.

[0056] During use, a large amount of dry bedding material is added to the fermentation tank at once. The height of the bedding material in the fermentation tank should not be less than 1.8 meters, and the volume of the bedding material should be greater than 60 times the daily manure treatment volume. The manure collected daily in the livestock and poultry house (solid content ≥5%) is evenly sprayed onto the bedding material and transported to the fermentation bed 3 periodically or continuously through the transmission unit. During the transmission process, a flow sensor can be set to monitor the flow rate of the manure to calculate the manure treatment volume and evaluate the manure treatment capacity of the fermentation bed 3. The turning machine 2 starts according to the preset operating cycle. The turning machine 2 adopts a low-power multi-layer turning and churning device. The bedding material inoculum uses a highly efficient degrading strain that can quickly decompose the residual starch in the manure. The turning machine 2, which is slidably connected to the side wall of the fermentation bed 3, starts to work, mixing and stirring the bedding material and manure. The turning and raking depth should be greater than 1.5m, ideally between 1.5 and 1.8m, to ensure thorough mixing of the bedding material and manure. The turning and raking machine 2 should be 10-15cm off the ground to avoid excessive wear on the bottom of the fermentation bed 3. The rake teeth should not be too short, otherwise the bottom bedding material will not mix evenly with the manure slurry, reducing treatment efficiency. After the bedding material and manure are evenly mixed, the moisture content should be controlled at 50%-60%. A suitable amount of manure can be sprayed once a day, and the material turned and raked once a day. The frequency of turning and raking can be increased in summer and reduced in winter.

[0057] The aeration unit, based on the concentration data of gases such as oxygen, carbon dioxide, ammonia, hydrogen sulfide, and particulate matter in fermentation chamber 1 monitored by gas sensors, adjusts the working status of the vortex air pump through the control module to provide an appropriate amount of air to fermentation bed 3, promoting uniform distribution of materials and sufficient contact with oxygen. Aeration pipes are fixedly connected to the aeration ditch at the bottom of fermentation chamber 1 to ensure that air is evenly distributed throughout the entire fermentation bed 3.

[0058] The spraying unit, based on the humidity data of the bedding material in fermentation bed 3 monitored by temperature and humidity sensors, adjusts the working status of the sewage pump through the control module to spray an appropriate amount of water into fermentation bed 3 to maintain suitable humidity. The spray nozzles are fixedly connected to the turning machine 2, and spray evenly as the turning machine 2 moves, ensuring uniform bedding material humidity. The effective volume of the temporary storage tank is determined according to the number of pigs raised, with a minimum of 0.35 m³ per pig. 3 The temporary storage pool is constructed underground with anti-seepage measures, and is surrounded by a roof to prevent rainwater from entering.

[0059] Based on the temperature and humidity data of the bedding material obtained from the data analysis module, the feeding unit adds an appropriate amount of microorganisms to the fermentation bed 3 through the control module. The microorganisms are evenly sprayed onto the bedding material through the sprinkler pipe, which helps to improve the fermentation effect and accelerate the process of converting manure into organic fertilizer.

[0060] During the operation of fermentation chamber 1 and fermentation bed 3, temperature and humidity sensors, flow sensors, cameras, and gas sensors continuously monitor the environmental conditions inside fermentation bed 3 and transmit the data to the receiving module. The temperature and humidity sensors monitor the temperature of fermentation bed 3 to track the fermentation process. The temperature of fermentation bed 3 is between 40℃ and 80℃. The data comparison module compares the received data with a preset threshold or standard. If the temperature is below 40℃, an early warning module is triggered. The early warning module notifies the user via sound alarm, flashing lights, or remote information to adjust the temperature of the bedding material in fermentation bed 3. When the temperature of fermentation bed 3 exceeds 50℃, the transmission unit adds manure to the bedding material. If the temperature information received by the data comparison module is between 40℃ and 50℃, the control module only activates the turning and rake machine 2 to turn the bedding material, and the transmission unit does not add manure until the bedding temperature rises to 50℃.

[0061] The temperature and humidity sensor also adjusts the spray unit to replenish water appropriately based on the monitored moisture status of fermentation bed 3. The humidity range of fermentation bed 3 in the data comparison module is 50%–60%. When the bedding material humidity is less than 40%, the control module starts the sewage pump to draw manure from the temporary storage tank and spray it evenly onto the bedding material of fermentation bed 3 until the humidity of fermentation bed 3 measured by the temperature and humidity sensor reaches 55%. When adding manure to the bedding material of fermentation bed 3, the amount is calculated based on the per cubic meter of bedding material in fermentation bed 3. 3Add no more than 25 kg of manure, and the recording module records the operation of fermentation bed 3 to provide a reference for the amount of manure to be added.

[0062] When the temperature and humidity sensor detects that the center temperature of the bedding material is below 50%, the data comparison module determines that the activity of probiotics in the bedding material has decreased. The control module adds microorganisms to the fermentation bed 3 and sends an early warning module to notify the user to replenish the bedding material. During operation, when the camera detects that the bedding material has settled too much or the temperature and humidity sensor detects that the bedding material humidity is too high, the early warning module also notifies the user to replenish the bedding material in time to avoid heat loss due to insufficient bedding material thickness or excessive humidity leading to bed death.

[0063] The recording module records historical data on abnormal events for subsequent analysis and improvement. The display module presents the system's operating status, monitoring data, control commands, and recorded data to the user in graphical or textual form, facilitating real-time monitoring and data analysis. The recording module also records key data such as the number of times the turning unit turns, the spraying volume of the spraying unit, the feeding volume of the feeding unit, and the temperature and humidity of fermentation chamber 1 and fermentation bed 3, providing important references for system optimization and maintenance.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.

It is higher than the ground on all sides and is covered with a top cover to prevent rainwater from entering. Temperature and humidity sensors are used to monitor the temperature and humidity of the fermentation house (1), fermentation bed (3) and bedding pile, and transmit the data to the receiving module. The temperature of the fermentation bed (3) is between 40℃ and 80℃. The data comparison module compares the received data with the preset threshold or standard. If the temperature is below 40℃, the warning module is triggered. The warning module notifies the user by sound alarm, light flashing or remote information to adjust the bedding temperature of the fermentation bed (3). When the temperature of the fermentation bed (3) is above 50℃, the transmission unit adds manure to the bedding of the fermentation bed (3). If the temperature information received by the data comparison module is between 40℃ and 50℃, the control module only starts the turning machine (2) to turn the bedding, and the transmission unit does not add manure until the bedding temperature rises to 50℃.
