[0002] In modern agriculture and animal husbandry, the treatment and resource utilization of animal manure is a crucial issue. With the widespread adoption of large-scale farming, the volume of animal manure produced is increasing dramatically. Traditional treatment methods, such as natural composting and simple composting, often fail to meet environmental protection and resource utilization requirements. These methods not only waste valuable organic resources but can also lead to environmental pollution, such as eutrophication of water bodies and soil contamination. While some existing treatment equipment and technologies have improved manure treatment efficiency to some extent, they still suffer from slow processing speeds, low resource utilization rates, and complex operations. Furthermore, these devices often require significant energy and labor inputs, increasing the operating costs of animal husbandry. Therefore, developing an efficient, economical, and environmentally friendly animal manure treatment and resource utilization system is of great significance for achieving the sustainable development of animal husbandry.

[0025] This utility model provides a device for efficient treatment and resource utilization of animal manure, aiming to solve the problems of low treatment efficiency and low resource utilization rate of animal manure in the prior art. Specifically, it includes a collection device 1 installed at the manure outlet of the farm, a pretreatment device 2 connected to the collection device 1 via a conveying pipe, a fermentation device 3 connected to the pretreatment device 2, a separation device 5 connected to the fermentation device 3, a solid fertilizer storage device 6 and a liquid fertilizer storage device 7 connected to the separation device 5, and a waste gas treatment device 8 installed above the fermentation device 3. The specific structure and working principle of the connection and control system 4 between the devices are as follows:

[0026] First, refer to Figure 1 As shown, the overall structure of the efficient animal manure treatment and resource utilization device includes a collection device 1, a pretreatment device 2, a fermentation device 3, a separation device 5, a solid fertilizer storage device 6, a liquid fertilizer storage device 7, and a waste gas treatment device 8. The collection device 1 is located at the manure outlet of the farm and is used to collect animal manure. The pretreatment device 2 is connected to the collection device 1 via a conveying pipe and is used to perform preliminary treatment on the collected manure, including crushing and mixing. The fermentation device 3 is connected to the pretreatment device 2 and is used to ferment the pretreated manure. The separation device 5 is connected to the fermentation device 3 and is used to separate the fermented material into solid and liquid components. The solid fertilizer storage device 6 and the liquid fertilizer storage device 7 are respectively connected to the separation device 5 and are used to store the separated solid and liquid fertilizers. The waste gas treatment device 8 is located above the fermentation device 3 and is used to treat harmful gases generated during the fermentation process.

[0027] Combination Figure 2The collection device 1 specifically includes a horizontally arranged manure collection plate 11, a drive wheel 12 located at the bottom of the manure collection plate 11, several columns 13 located on the upper surface of the manure collection plate 11, a solar panel 14 horizontally located at the top of the columns 13, and the drive wheel 12 mounted on a ground rail 15. The drive wheel 12 can move on the ground rail 15 to ensure that the manure collection plate 11 can cover the entire manure outlet area of ​​the farm. The solar panel 14 can provide clean energy for the collection device 1 and other electrical equipment in the entire device, reducing energy consumption. When animal manure enters the collection device 1, the drive wheel 12 drives the manure collection plate 11 to move, concentrating the manure at the inlet of the conveying pipe. The conveying pipe transports the manure to the pretreatment device 2.

[0028] Pretreatment device 2 includes a pulverizer 21 and a mixer 22 arranged in sequence, for reference. Figure 1 and Figure 2 Animal manure enters the pulverizer 21 through a conveying pipe, where it undergoes preliminary pulverization to make the particles smaller and more uniform. The pulverized manure then enters the mixer 22 through the conveying pipe, where it is thoroughly mixed to ensure even distribution before entering the fermentation device 3. The pulverizer 21 and mixer 22 are connected to the control system 4 via wires, which control the motor's operation to ensure the smooth progress of the pretreatment process.

[0029] Fermentation device 3 has a diameter greater than 10 meters and a height greater than 5 meters, for reference. Figure 1 and Figure 3 The fermentation device 3 is equipped with a temperature sensor 31 and a humidity sensor 32 for real-time monitoring of the temperature and humidity of the fermentation environment. The fermentation device 3 is also connected to a control system 4, which contains a fermentation control program. The temperature sensor 31 and humidity sensor 32 are connected to the control system 4. The control system 4 is connected to a heating device 33 and a humidification device 34 via wires. Based on the real-time data monitored by the temperature sensor 31 and humidity sensor 32, the control system adjusts the operating status of the heating device 33 and the humidification device 34 to ensure efficient and stable fermentation. The fermentation control program can refer to or adopt a biological fermentation control system. This system pre-programs the optimal fermentation conditions and adjusts the operating status of the heating and humidification devices in real-time based on monitoring data to ensure efficient fermentation.

[0030] During fermentation, the organic matter in the manure undergoes biodegradation under the action of microorganisms, generating solid and liquid fertilizers. To ensure the smooth progress of the fermentation process, the control system 4 monitors the temperature and humidity of the fermentation environment in real time using a temperature sensor 31 and a humidity sensor 32. When the temperature sensor 31 detects that the temperature is lower than the set value, the control system 4 activates the heating device 33 to raise the temperature of the fermentation environment; when the humidity sensor 32 detects that the humidity is lower than the set value, the control system 4 activates the humidification device 34 to raise the humidity of the fermentation environment. In this way, fluctuations in temperature and humidity during fermentation can be effectively avoided, ensuring the efficient and stable fermentation process.

[0031] After fermentation is complete, the fermented material is transported to the separation device 5 via a pump 51 installed on the pipeline between the fermentation device 3 and the separation device 5. (Refer to...) Figure 1 and Figure 4 The separation device 5 includes a solid-liquid separation unit and a solid-liquid separation sensor 52, which can monitor the efficiency of solid-liquid separation in real time. When the separation device 5 receives the fermented material, it separates the solid and liquid components. The solid component is transported through a pipeline to a solid fertilizer storage device 6, and the liquid component is transported through a pipeline to a liquid fertilizer storage device 7. The solid-liquid separation sensor 52 is connected to a control system 4, which controls the operating status of the pump 51 based on the monitoring data to ensure the efficient operation of the separation process.

[0032] The solid fertilizer storage device 6 is equipped with a second humidity sensor 61 and a second heating device 62, for reference. Figure 1 and Figure 4 The second humidity sensor 61 monitors the humidity of the solid fertilizer in real time and transmits the data to the control system 4. The control system 4 adjusts the operating state of the second heating device 62 based on the data from the second humidity sensor 61 to ensure the dryness of the solid fertilizer, facilitating storage and transportation. The second heating device 62 is connected to the control system 4 via a wire, allowing the control system 4 to control its operating state. When the second humidity sensor 61 detects that the humidity of the solid fertilizer exceeds a set value, the control system 4 activates the second heating device 62, which reduces the humidity of the solid fertilizer through heating, ensuring its dryness.

[0033] The main function of the liquid fertilizer storage device 7 is to store the separated liquid fertilizer. (Refer to...) Figure 1 and Figure 4The liquid fertilizer storage device 7 is connected to the separation device 5 via a pipeline. After the separation device 5 separates the liquid fertilizer, it is transported through the pipeline to the liquid fertilizer storage device 7 for storage. The capacity of the liquid fertilizer storage device 7 can be designed according to the actual scale of the farm to ensure that the storage needs of the liquid fertilizer are met. The liquid fertilizer storage device 7 is also equipped with a liquid level sensor and a temperature sensor to monitor the liquid fertilizer level and temperature in real time, ensuring the safe storage of the liquid fertilizer.

[0034] To address the harmful gases produced during fermentation, such as ammonia and hydrogen sulfide, this invention also includes a waste gas treatment device 8. (See reference...) Figure 1 and Figure 3 The waste gas treatment device 8 includes a filter 81 and an absorption tower 82 arranged sequentially, and a fan 83 positioned between the filter 81 and the absorption tower 82. The filter 81 is used to initially remove large particulate matter from the waste gas, preventing large particles from entering the absorption tower 82 and affecting the treatment effect. The fan 83 is connected to the control system 4 via wires. The control system 4 can adjust the operating status of the fan 83 according to the concentration of harmful gases to ensure effective extraction of waste gas. The absorption tower 82 is used to further treat the harmful gases in the waste gas by adding chemical agents to remove harmful gases such as ammonia and hydrogen sulfide. A dosing device 84 is connected to the control system 4 via wires. The control system 4 can adjust the operating status of the dosing device 84 according to the concentration of harmful gases to ensure accurate dosing.

[0035] In practical applications, this utility model's efficient animal manure treatment and resource utilization device can be widely used in various types of farms. For example, in large-scale pig farms, pig manure is collected centrally by a manure collection plate 11. The power wheels 12 on the manure collection plate 11 move on a ground rail 15, transporting the manure to a crusher 21 for crushing. The crushed manure is then thoroughly mixed by a mixer 22 to ensure uniform mixing, and then enters the fermentation device 3 through a conveying pipe. Temperature sensors 31 and humidity sensors 32 within the fermentation device 3 monitor the temperature and humidity of the fermentation environment in real time. The control system 4 adjusts the operating status of the heating device 33 and the humidification device 34 based on the monitoring data to ensure efficient and stable fermentation. After fermentation, the fermented material is transported to a separation device 5 by a pump 51, which separates the solid and liquid fertilizers. The solid fertilizer is transported through a pipeline to a solid fertilizer storage device 6, and the liquid fertilizer is transported through a pipeline to a liquid fertilizer storage device 7. The second humidity sensor 61 and the second heating device 62 on the solid fertilizer storage device 6 ensure the dryness of the solid fertilizer, while the liquid level sensor and temperature sensor on the liquid fertilizer storage device 7 ensure the safe storage of the liquid fertilizer. In addition, the waste gas treatment device 8 is connected to the fermentation device 3 through a pipeline, and the filter 81 and absorption tower 82 can effectively remove harmful gases generated during the fermentation process, ensuring the environmental quality of the farm.

[0036] In practice, the processing capacity of the waste gas treatment device 8 can be adjusted according to the actual amount of feces produced and the concentration of harmful gases. For example, if a large amount of harmful gases are produced during fermentation, the processing capacity of the filter 81 and the absorption tower 82 can be increased. The specific adjustment range can be determined based on actual needs. This adjustment is very easy to implement for those skilled in the art.

[0037] This utility model's efficient animal manure treatment and resource utilization device not only efficiently treats animal manure but also converts it into solid and liquid fertilizers, achieving resource utilization and possessing multi-functional technical benefits. During the design process, the connections between various devices and the configuration of the control system 4 were carefully considered and optimized to ensure the device's efficient and stable operation. Furthermore, by incorporating solar panels 14, clean energy can be provided to the device, reducing energy consumption and further improving its environmental friendliness and economic efficiency. Overall, this utility model's efficient animal manure treatment and resource utilization device has a very broad application prospect in practical applications. It can not only solve the manure treatment problem in farms but also effectively improve resource utilization, resulting in significant economic and environmental benefits.
