Description

Technical Field

[0001] The present invention relates to the technical field of livestock breeding, and particularly relates to a deep-tank off-site fermentation bed system for converting fecal and sewage into organic fertilizer. Background Art

[0002] The off-site fermentation bed system is an innovative technology for treating livestock and poultry fecal and sewage, aiming to convert the fecal and sewage generated during the livestock and poultry breeding process into organic fertilizers. This system sets up a fermentation bed outside the livestock and poultry breeding house, evenly sprays the fecal and sewage collected every day (such as pig manure and urine) onto the bedding in the fermentation tank, and uses the fermentation of microorganisms for high-temperature aerobic fermentation, thereby realizing the harmless treatment and resource utilization of fecal and sewage. This technology not only solves the ecological environmental pollution problems caused by improper treatment and random discharge of livestock and poultry fecal and sewage, but also realizes the effective recovery and utilization of resources by producing organic fertilizers.

[0003] However, although the off-site fermentation bed system has many advantages, in practical applications, there are still some obvious defects in the existing technology. First of all, currently, livestock and poultry breeding generally faces the problem of insufficient matching of fecal and sewage treatment facilities and equipment, resulting in low fecal and sewage treatment efficiency and being unable to meet the demand for expanding the breeding scale under the condition of limited land use. The existing off-site fermentation bed technology has limited fecal and sewage treatment capacity and poor treatment effect. For example, in the patent with the authorization announcement number "CN 206909383U", the height of the off-site fermentation bed is <1.2 m, and the bedding thickness is only 60 - 70 cm, which is significantly insufficient in terms of fecal and sewage treatment volume. This seriously affects the treatment volume effect of fecal and sewage and the expansion of the breeding scale. The ventilation and oxygen supply conditions inside the fermentation bed are limited, resulting in poor fermentation effect and easy occurrence of dead bed phenomenon. In addition, the existing technology also has problems such as insufficient ventilation and oxygen supply and no sewage reflux. Insufficient ventilation and oxygen supply will lead to insufficient oxygen supply inside the fermentation bed, affecting the fermentation of microorganisms and thus reducing the fecal and sewage treatment efficiency. Without sewage reflux, the humidity of the fermentation bed will be too high, further affecting the fermentation effect. These problems not only limit the application effect of the off-site fermentation bed system, but also may lead to incomplete fecal and sewage treatment and even cause secondary pollution. At the same time, due to limited fecal and sewage treatment, the breeding scale is restricted, seriously affecting the income-generating ability of the breeding industry.

[0004] In summary, although the off-site fermentation bed system has significant environmental protection and resource utilization advantages, there are still some technical defects in practical applications. To solve these problems, it is necessary to further optimize the system design. Summary of the Invention

[0005] To solve the above problems, the present invention provides a deep-tank off-site fermentation bed system for converting manure into organic fertilizer, which is used to increase the volume and efficiency of manure treatment, strengthen the ventilation and oxygen supply conditions, and set up a sewage reflux system to ensure the maximization of manure treatment effect and resource utilization, and promote the development of the aquaculture industry.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A deep-tank off-site fermentation bed system for converting manure into organic fertilizer, comprising a fermentation shed and a fermentation bed. The fermentation bed is located inside the fermentation shed and is used to collect and accommodate the mixture of livestock and poultry manure and bedding. It also includes a control system, a monitoring instrument, and a processing device that are signal-connected to each other. The processing device is used to process the manure in the fermentation bed, the monitoring instrument is used to collect the environmental conditions inside the fermentation bed and transmit them to the control system, and the control system is used to issue information warnings according to the monitoring data collected by the monitoring instrument and control the processing device to perform operations on the manure in the fermentation bed.

[0007] The processing device includes a transmission unit, a turning unit, an aeration unit, a feeding unit, and a spraying unit. The monitoring instrument includes a temperature and humidity sensor, a flow sensor, a camera, and a gas sensor.

[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 it operates according to the initially set operation 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 warning module.

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

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

[0017] Furthermore, the spraying unit is used to increase the manure and humidity of the bedding in the spraying fermentation bed. The spraying unit includes a storage tank and several spraying pipes. The storage tank is arranged on one side of the fermentation bed, and a sewage pump is arranged inside the storage tank. The output end of the sewage pump is communicated with the input end of the spraying pipe. The spraying pipes are all fixedly connected to the top of the fermentation house, and the output ends of the spraying pipes are all communicated with spray heads, and the spray heads are all fixedly connected to the turning rake machine.

[0018] Furthermore, the feeding unit is used to analyze the temperature and humidity of the bedding according to the data analysis module and 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 rake machine, and a material spraying pipe is communicated with the bedding box. The material spraying pipe is fixedly connected to the connecting rod of the turning rake machine.

[0019] Furthermore, the camera is used to monitor and record the on-site operation scenario of the off-site fermentation bed to make up for the situation where there is data but no picture from the monitoring sensor or no effective data can be monitored due to the failure of the monitoring equipment, and to help the farm make an auxiliary judgment on the operation effect of the off-site fermentation bed.

[0020] Furthermore, the temperature and humidity sensor is used to monitor the temperature and humidity of the fermentation house, fermentation bed and bedding pile and transmit them to the receiving module.

[0021] Furthermore, the flow sensor is used to monitor and collect the manure treatment volume, and calculate the manure treatment capacity of the off-site fermentation bed in each time period through time parameter accumulation.

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

[0023] The above-mentioned solution has the following beneficial effects:

[0024] 1.

[0025] 2. In this solution, the setting of the aeration unit can intelligently adjust the aeration volume according to the real-time monitoring data of oxygen, carbon dioxide, ammonia, hydrogen sulfide gas and particulate matter in the fermentation house, ensuring that the internal materials of the fermentation bed are fully in contact with oxygen, promoting the activity and reproduction of microorganisms, thereby improving the fermentation efficiency and quality, and avoiding the problem of poor fermentation effect caused by insufficient oxygen supply.

[0026] 3. In this solution, the design of the spraying unit can not only add appropriate manure and humidity to the bedding in the fermentation bed, but also realize the effective reflux and reuse of sewage through the connection between the storage tank and the spraying pipeline, reducing the waste of water resources, and at the same time helping to maintain the humidity balance in the fermentation bed and improving the fermentation effect.

[0028] 5. In this solution, through the design of the recording module and the display module, users can conveniently view the operating status, monitoring data, control instructions and historical records of the system, providing great convenience for the maintenance and management of the system. At the same time, the existence of the warning module can timely notify users when abnormal situations occur, avoiding potential risks and enhancing the reliability of the system; the setting of the camera can not only provide effective on-site pictures when the monitoring sensor fails, but also help farmers intuitively understand the operating conditions of the fermentation bed, providing important visual information for assisting in judging the fermentation effect.

[0046] The transmission unit is used to transmit the manure generated in the livestock and poultry house to the fermentation bed 3.

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

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

[0049] The spraying unit is used to increase manure and humidity for the bedding in the spraying fermentation bed 3. The spraying unit includes a storage tank and several spraying pipes. The storage tank is arranged on one side of the fermentation bed 3. A sewage pump is arranged in the storage tank. The output end of the sewage pump is communicated with the input end of the spraying pipe. The spraying pipes are all fixedly connected to the top of the fermentation house 1. The output ends of the spraying pipes are all communicated with spray heads, and the spray heads are all fixedly connected to the turning rake machine 2.

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

[0051] The camera is used to monitor and record the on-site operation scene of the off-site fermentation bed 3 to make up for the situation where there is data but no picture for the monitoring sensor or no effective data can be monitored due to the failure of the monitoring equipment, and help the farm make an auxiliary judgment on the operation effect of the off-site fermentation bed 3.

[0052] The temperature and humidity sensor is used to monitor the temperature and humidity of the fermentation house 1, the fermentation bed 3 and the bedding pile, and transmit them to the receiving module.

[0053] The flow sensor is used to monitor and collect the manure treatment volume, and calculate the manure treatment capacity of the off-site fermentation bed 3 in each time period through time parameter accumulation.

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

[0055] The specific implementation process is as follows: First, the ground of the fermentation bed 3 is leveled, and the height difference between the front and the back does not exceed 5 cm. It is also necessary to ensure that rainwater cannot enter the fermentation bed 3 on rainy days, and make a good ditch to ensure that rainwater can be drained smoothly. The fermentation house 1 should be a closed rectangular parallelepiped, and the building area should be determined according to the breeding volume and the size of the site; the structural frame of the fermentation house 1 should be a reinforced concrete structure, and the roof should be paved with transparent lighting tiles. This design can make full use of solar energy and is conducive to the fermentation of fermented materials. The wall of the fermentation house 1 should be reinforced concrete with a thickness of 20-25cm, so that it is perpendicular to the horizontal plane. After the wall is completed, it is required to reach a height of 2-2.5m. A 25cm high concrete ring beam should be made at the top of the wall. To ensure that the turning and rake machine 2 is not easily worn, the top of the ring beam should be smooth and flat; to prevent the turning and rake machine 2 from derailing, the width of the empty space in the wall should be uniform, reaching 5-10 meters wide; the area of ​​the fermentation bed 3 should be designed according to the maximum number of seedlings in the pig house, and calculated according to the minimum demand of 0.25 square meters / head (preferably 0.3 square meters / head or more); a door should be left on the narrow side of the fermentation house 1, and a cut should be reserved so that the bedding can be cleaned and transported in the future; the bottom surface thickness of the fermentation bed 3 should be more than 20cm, and a sewage return ditch should be set. The return ditch should be 20cm wide and 15cm deep. The return ditch should be filled with gravel and covered with tiles to prevent the fermented material from entering the ditch. The return ditch is connected to the temporary storage tank through a pipe.

[0056] When in use, a large amount of dry bedding is put into the fermentation tank at one time. The height of the bedding in the fermentation tank should not be less than 1.8 meters, and the volume of the bedding should be greater than 60 times the daily amount of manure and sewage processed. The manure and sewage (solid content ≥5%) collected every day in the livestock and poultry house will be evenly sprayed on the bedding, and will be regularly or continuously transmitted to the fermentation bed 3 through the transmission unit. During the transmission process, a flow sensor can be set to monitor the flow of manure and sewage to calculate the amount of manure and sewage processed and evaluate the manure and sewage processing capacity of the fermentation bed 3. The turning and raking machine 2 is started according to the preset operation cycle. The turning and raking machine 2 adopts a low-power multi-layer turning and throwing device. The bedding strain adopts an efficient degradation strain that can quickly decompose the residual starch in the manure and sewage. The turning and raking machine 2 slidably connected to the side wall of the fermentation bed 3 starts to work and mixes and stirs the bedding and manure and sewage. The raking depth is greater than 1.5m, and preferably between 1.5 and 1.8m, to ensure that the litter and manure are fully mixed. At the same time, the raking machine 2 is 10 to 15cm above 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 litter cannot be mixed evenly with the manure slurry, reducing the processing efficiency. After the litter and manure are evenly mixed, the moisture content should be controlled at 50%-60%. Manure can be sprayed once and the material can be raked once a day. The number of raking can be appropriately increased in summer and reduced in winter.

[0057] The aeration unit adjusts the working state of the vortex air pump through the control module according to the concentration data of oxygen, carbon dioxide, ammonia, hydrogen sulfide and other gases and particulate matter in the fermentation house 1 monitored by the gas sensor, and provides an appropriate amount of air to the fermentation bed 3 to promote the uniform distribution of materials and sufficient contact with oxygen. The aeration pipe is fixedly connected to the aeration ditch at the bottom of the fermentation house 1 to ensure that the air can be evenly distributed throughout the fermentation bed 3.

[0058] The spray unit adjusts the working state of the sewage pump through the control module according to the humidity data of the litter in the fermentation bed 3 monitored by the temperature and humidity sensor, and sprays an appropriate amount of water into the fermentation bed 3 to maintain appropriate humidity. The nozzle is fixedly connected to the rake turning machine 2, and sprays evenly with the movement of the rake turning machine 2 to ensure uniform humidity of the litter. The effective volume of the temporary storage pool is determined according to the feeding amount, and is not less than 0.35m per pig in stock. 3 The temporary storage pool is built underground and anti-seepage treated. The surrounding area is higher than the ground and a cover is installed to prevent rainwater from entering.

[0059] The feeding unit adds an appropriate amount of microorganisms to the fermentation bed 3 through the control module according to the litter temperature and humidity data analyzed by the data analysis module. The microorganisms are evenly sprayed on the litter through the spraying pipe, which helps to improve the fermentation effect and accelerate the process of converting manure into organic fertilizer.

[0060] During the operation of the fermentation house 1 and the fermentation bed 3, the temperature and humidity sensor, flow sensor, camera and gas sensor continuously monitor the environmental conditions in the fermentation bed 3 and transmit the data to the receiving module. The temperature and humidity sensor monitors the temperature of the fermentation bed 3 to grasp the fermentation process. The temperature of the fermentation bed 3 is between 40°C and 80°C. The data comparison module compares the received data with the preset threshold or standard. If the temperature is lower than 40°C, the early warning module is triggered. The early warning module notifies the user through sound alarm, flashing lights or remote information, and adjusts the temperature of the fermentation bed 3 litter. When the temperature of the fermentation bed 3 is higher than 50°C, the transmission unit adds manure to the fermentation bed 3 litter. If the temperature information received by the data comparison module is 40°C to 50°C, the control module only starts the rake machine 2 to rake the litter, and the transmission unit does not add manure until the litter temperature rises to 50°C.

[0061] The temperature and humidity sensor also monitors the moisture status of the fermentation bed 3 and adjusts the spray unit to add water appropriately. The humidity range of the fermentation bed 3 in the data comparison module is 50% to 60%; when the humidity of the bedding is less than 40%, the control module starts the sewage pump to extract manure from the temporary storage tank and spray it evenly on the bedding of the fermentation bed 3 until the humidity of the fermentation bed 3 measured by the temperature and humidity sensor reaches 55%. When adding manure to the bedding of the fermentation bed 3, according to the fermentation bed 3 bedding per m 3Add a manure volume not exceeding 25 kg. Meanwhile, the recording module records the operation record of the fermentation bed 3, providing a reference basis for the added manure volume.

[0062] When the central temperature of the bedding measured by the temperature and humidity sensor is lower than 50%, the data comparison module determines that the activity of probiotics in the bedding has decreased. The control module adds microorganisms into the fermentation bed 3 and the warning module issues a notice to the user to supplement the bedding. During the operation, when the camera captures that the settlement of the bedding is too large or the humidity of the bedding obtained by the temperature and humidity sensor is too high, the warning module also notifies the user to supplement the bedding in time to avoid heat loss due to insufficient bedding thickness or dead bed caused by too high humidity.

[0063] The recording module records the historical data of abnormal events for subsequent analysis and improvement by the user. The display module presents information such as the operation status of the system, monitoring data, control instructions, and recorded data to the user in a graphical or text-based manner, facilitating the user to monitor the operation of the system in real time and conduct data analysis. The recording module is used to record key data such as the turning times of the turning unit, the spraying volume of the spraying unit, the feeding volume of the feeding unit, and the temperature and humidity of the fermentation house 1 and the fermentation bed 3, providing an important reference for the optimization and maintenance of the system.

[0064] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. The obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
