[0001] This invention relates to the field of poultry manure treatment technology, and in particular to an environmentally friendly poultry manure treatment system. Background Technology

[0002] Poultry farming is an important part of global agricultural production. During the farming process, poultry produce manure, a complex substance composed of excrement, food residue, metabolic waste, and microorganisms. Poultry manure treatment is a crucial and indispensable aspect of modern poultry farming. With the expansion of poultry farming, poultry manure treatment has increasingly become a source of environmental pollution.

[0003] In related technologies, the manure produced by poultry and livestock farming is usually processed into organic fertilizer. The manure is often separated into solid and liquid components using a solid-liquid separator, and then dried or piled up.

[0004] However, traditional processing methods require manual operation step by step, which is time-consuming, labor-intensive, inefficient, and involves complicated and cumbersome steps that cannot be integrated. In addition, the accumulation of feces during the processing can cause secondary pollution to the environment and breed bacteria, affecting the growth of poultry. Summary of the Invention

[0005] This invention addresses the problems of traditional poultry manure treatment methods, which require manual, step-by-step operations, are time-consuming, labor-intensive, inefficient, and involve complex and cumbersome processes that cannot be integrated.

Detailed Implementation

[0019] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0020] like Figures 1 to 8 As shown, this invention discloses an environmentally friendly poultry manure treatment system, including a chamber 1, a collection mechanism 2, a separation device 3, and a treatment mechanism. The chamber 1 is used to house poultry. The bottom of the chamber 1 is provided with a bottom plate 12 and a perforated manure-leaking plate 11 spaced apart. The bottom plate 12 is located below the manure-leaking plate 11 and forms a cavity 13 between them. The cavity 13 is used to collect manure and prevent leakage and pollution of the breeding environment. The structure of the manure-leaking plate 11 can be square or circular, and can be adapted as needed. In one example, the manure-leaking plate 11 is composed of multiple square structures spliced ​​together. The perforated manure-leaking plate 11 allows manure to fall through the holes into the cavity 13 below when poultry defecate. In addition, the manure-leaking plate 11 can separate poultry and manure, ensuring a clean poultry environment and preventing poultry from falling and causing life-threatening situations.

[0021] The collection mechanism 2 is located inside the cavity 13. The collection mechanism 2 is used to collect and transport feces. The collection mechanism 2 includes a scraper 22 connected to the chamber 1 via a moving mechanism 21. The moving mechanism 21 can drive the scraper to move back and forth along a preset trajectory. The moving mechanism 21 can be a gear mechanism, a screw motor drive structure, or a chain mechanism, etc., as long as it can move the scraper 22. It can be adapted to meet the requirements. The scraper 22 is installed on the moving mechanism 21 through a support structure. The scraper 22 has an arc-shaped structure. The arc-shaped scraper 22 can evenly distribute the force used to scrape the feces, thereby improving the feces collection efficiency. During use, the scraper 22 is in close contact with the manure-leaking plate 11 and the bottom plate 12. The moving mechanism 21 is driven to move the scraper 22 along the length of the chamber 1, thereby pushing the collected feces to the required position.

[0022] Continue to refer to Figures 1 to 8 The separation device 3 is located outside the housing 1. It is used to separate the collected manure into solid and liquid components. The device includes an L-shaped connector 31 and a separator 32. One end of the connector 31 is connected to the housing 1, and the other end is connected to the separator 32, allowing the cavity 13 to communicate with the interior of the separator 32. This enables a sealed transport of manure from the cavity 13 to the separator 32, preventing leakage or odor spread, thus avoiding environmental pollution and harm to poultry hygiene. The separator 32 effectively separates the liquid (e.g., wastewater) from the solid (e.g., manure residue) in the manure, facilitating subsequent processing or resource utilization. A processing mechanism is connected to one side of the separator 32. This mechanism processes the separated manure and can be a fermentation module, a purification module, or a recycling module, thereby improving environmental efficiency and resource utilization.

[0023] During use, poultry live in chamber 1, and their droppings fall through the slatted floor 11 onto the base plate 12. The operator drives the moving mechanism 21 to move the scraper 22 along the length of chamber 1 (e.g., ...). Figure 1 The reciprocating motion (in the x direction shown in the figure) scrapes the feces through the connector 31 into the separator 32 for solid-liquid separation. Both the solid and liquid parts are processed by the treatment mechanism to prevent fecal pollution and improve resource utilization.

[0024] In this application, the automatic collection and transportation of feces is achieved by combining and integrating the collection mechanism, separation device, and treatment mechanism, reducing the frequency of manual cleaning. The moving mechanism drives the scraper to move, and the L-shaped connectors are connected to the chamber and the separator, which can realize closed solid-liquid separation and pollution isolation, preventing secondary pollution and odor diffusion. This results in efficient resource utilization and the production of stable fertilizers and energy, effectively protecting the environment.

[0025] In some embodiments, such as Figure 1 As shown, along the width direction of room 1 (e.g.) Figure 1 (As shown in the y-direction), the length of the connector 31 is greater than the length of the scraper 22, allowing the scraper 22 to cover a wider area throughout its movement range. The connector 31 can also effectively limit the position of the feces transport, thereby ensuring that the feces fall precisely into the separator 32 for efficient solid-liquid separation.

[0026] In one example, the moving mechanism 21 employs a gear mechanism, comprising a sector gear 211 and a rack 212 mounted on a gear 210. Multiple gears 210 are provided, with both the sector gear 211 and rack 212 mounted on each gear 210. Two sector gears 211 are provided, and the rack 212 is located between the two sector gears 211. A scraper 22 is mounted on the rack 212 via a support structure. In one example, the scraper 22 is angularly adjustable relative to the rack 212 along the circumferential direction of the support structure. This achieves precise and efficient collection, reduces the cost of manual intervention, improves overall collection efficiency, and enhances the hygiene of the livestock shed. Simultaneously, the scraper 22, along the gear 210, drives the sector gear 211 and its meshing rack 212 to move linearly, causing the scraper 22 to move closer to or further away from the separation device 3. That is, when the feces in the cavity 13 need to be cleaned, the angle of the scraper 22 is adjusted so that the bottom of the scraper 22 is tightly fitted with the bottom plate 12, driving the sector gear 211 to move the scraper 22 on the rack 212 along the length of the shed 1 (e.g., ...). Figure 5 The scraper 22 moves linearly (indicated by the x-arrow in the diagram) to bring it closer to the separator 32 and scrape the feces into the separator 32. After cleaning, the angle of the scraper 22 is adjusted again so that the scraper 22 moves away from the bottom plate 12. At the same time, the sector gear 211 is driven to drive the scraper 22 on the rack 212 along the length of the chamber 1 (e.g., as shown by the x-arrow in the diagram). Figure 5 The x-arrow shown indicates the opposite direction. Move the scraper 22 away from the separator 32 in a straight line to move the scraper 22 back to its original position to avoid affecting normal operation. When there is still residual feces on the bottom plate 12, clean the feces on the bottom plate 12 again according to the above steps to improve flexibility and thoroughness.

[0027] In some embodiments, such as Figures 1 to 5 As shown, the scraper 22 is composed of a flexible scraping part 220 and a fixing part 221, along the height direction of the scraper 22 (e.g., Figure 5(shown in the z-direction) The scraping part 220 is located on both sides of the fixing part 221. The scraping part 220 is made of flexible material, such as rubber, plastic and fiber. In one example, the scraping part 229 is made of silicone and is connected to the fixing part 221 by a spring. The silicone material has good flexibility and wear resistance, and can effectively fit the irregular parts of the surface. The spring provides elastic support, so that the scraping part 229 can adapt to the surface undulations. During the scraping process, it forms a good fit with the top surface of the base plate 12 and the bottom surface of the manure leakage plate 11. This ensures that while cleaning the feces on the surface of the base plate 12 and the manure leakage plate 11, it avoids damage to the surface and wear, thus enhancing durability. The fixing part 221 is used to stabilize the overall structure of the scraper 22 and is connected to the rack 212 on the moving mechanism 21 through the support structure, so as to realize the cleaning and transportation of feces and improve the stable operation of feces collection.

[0028] In some embodiments, such as Figure 1 and Figure 6 As shown, the separator 32 has a screw shaft 321, a discharge port 322, and a drain port 323. The discharge port 322 is located on one side of the separator 32, and the drain port 323 is located at the bottom of the separator 32. The screw shaft 321 is located along the direction of manure conveying (e.g., ...). Figure 1 As shown in the y-direction, the diameter of the spiral shaft 321 gradually increases, effectively compressing and squeezing the feces. During the feces transportation process, the increasing diameter of the spiral shaft 321 gradually enhances the pushing force on the feces, thereby effectively pushing the feces to flow along the transportation direction. By continuously increasing the pressure, the solid and liquid parts of the feces are more thoroughly separated. The spiral shaft 321 has spiral grooves on its surface, which can improve the friction between the spiral shaft 321 and the feces, making the feces move more smoothly on the axial surface of the spiral shaft 321 and effectively enhancing the gripping force on the feces. This helps to separate the solid part of the feces from the liquid, pushing the solid part to the discharge port 322, while the liquid part is discharged along the drain port 323. This makes the solid part of the feces drier, which is convenient for subsequent composting, and the liquid part of the feces purer, which is beneficial for subsequent processing such as fermentation. At the same time, it can improve the processing efficiency and processing capacity of the separator 32, making the solid-liquid separation process in the feces more efficient and uniform.

[0029] In some embodiments, such as Figure 1 and Figure 6As shown, the drain outlet 323 is equipped with a screen device 324, which can further improve the separation effect and the precise control of the draining process. The screen device 324 consists of multiple independently openable and closable small units, each equipped with an individual control mechanism that can automatically adjust its opening or closing according to the characteristics of the liquid and the separation requirements. In one example, the control mechanism includes a pressure sensor 325 and a controller 326. Each unit is connected to the pressure sensor 325, and the pressure sensor 325 is electrically connected to the controller 326 for the screen aperture size of the control unit. During use, the pressure sensor 325 can monitor the pressure on each unit in real time and transmit the detected pressure signal to the controller 326. The controller 326 can monitor the changes in liquid flow rate in real time and whether there is blockage or excessive accumulation in each unit. When the pressure in a certain area is too high, the corresponding unit automatically enlarges the screen hole size to accelerate the liquid outflow and balance the pressure, preventing screen blockage. After the pressure returns to normal, the unit restores the original hole diameter to ensure separation accuracy. This ensures that the screen device 324 at the drain port 323 is always kept in the best condition, effectively improving the adaptability and stability of the solid-liquid separation module, improving the efficiency and quality of solid-liquid separation, and reducing equipment failure and maintenance frequency.

[0030] In some embodiments, such as Figure 1 , Figure 7 and Figure 8 As shown, the processing mechanism includes a composting device 41 and a fermentation tank 42. The discharge port 322 is connected to the composting device 41 via a first pipe fitting 5. The composting device 41 is used to process the solid portion discharged from the discharge port 322 of the separator 32. The solid portion contains organic matter that can be converted into organic fertilizer for use in agricultural or horticultural applications. The composting device 41 can provide suitable temperature, humidity, and oxygen supply to promote the rapid decomposition of microorganisms, thereby accelerating the degradation process of organic matter. The liquid outlet 323 is connected to the fermentation tank 42 via a second pipe fitting 6. The fermentation tank 42 is a closed reaction vessel used for biological fermentation of the liquid portion, decomposing the organic matter therein and removing harmful components. Under controlled temperature and humidity conditions, it can gradually convert the organic matter in the liquid portion into useful products (such as biogas, fertilizer liquid, etc.), thereby making reasonable use of manure and reducing environmental pollution.

[0031] In some embodiments, continue to refer to Figure 1 , Figure 7 and Figure 8The composting equipment 41 has a multi-layered internal structure, with each layer connected by an adjustable partition 410. The adjustable partition 410 facilitates the transfer of the solid parts of the manure between different layers, achieving layered composting. At the same time, the side walls of the composting equipment 41 have openings, allowing operators to use a turner to turn the solid parts at the bottom to the top, and so on, to achieve composting. Adjusting the partition 410 ensures that the solid parts between each layer can be evenly supplied with oxygen and that microorganisms can work together, thereby accelerating the decomposition process.

[0032] The composting equipment 41 also includes an airflow-guided ventilation device 411. The ventilation device 411 is located at the bottom of the composting equipment 41 and can effectively guide air to be evenly distributed in each layer of the internal structure of the composting equipment 41, so that the air can circulate between each layer of the structure, ensuring that each layer of solid part can obtain sufficient oxygen supply, thereby accelerating the degradation process of the solid part and improving the quality of the final compost solid part, while reducing the impact on the environment, making the composting process more efficient and environmentally friendly.

[0033] In some embodiments, such as Figure 1 and Figure 8 As shown, the fermenter 42 consists of an inner layer 420 and an outer layer 421. The inner layer 420 has a stirring blade 422 with a spiral structure. The spiral blade 422 rotates to continuously agitate and stir the liquid in the fermenter 42, ensuring that the liquid comes into full contact with the microorganisms and oxygen in the fermenter 42, thereby promoting the degradation of organic matter. The rotation direction of the blade 422 is opposite to the flow direction of the liquid, ensuring that the liquid is evenly heated and inoculated during fermentation, thereby accelerating the fermentation reaction and improving processing efficiency. The outer layer 421 is equipped with a heating device 423, which is located between the inner layer 420 and the outer layer 421. The heating device 423 provides heat to the fermenter 42. In one example, the heating device 423 generates heat through a resistance wire with a temperature between 40°C and 70°C, which is beneficial to the activity of microorganisms in the liquid and the degradation of organic matter, and can accelerate the fermentation rate.

[0034] A biogas collection device 7 is also installed on one side of the fermentation tank 42. The biogas collection device 7 is used to collect the biogas produced during the fermentation process. The biogas collection device 7 is connected to the top of the fermentation tank 42 through a pipe 9. During use, the fermentation tank 42 effectively treats the liquid part and makes reasonable use of the biogas produced, thereby improving resource utilization efficiency.

[0035] In some embodiments, such as Figure 1As shown, it also includes a wastewater treatment unit 8, which is used to treat wastewater generated during use. The wastewater treatment unit 8 can be connected to both the composting equipment 41 and the fermentation tank 42. In one example, the wastewater treatment unit is connected to the fermentation tank 42. During the processing in the fermentation tank 42, a certain amount of water is generated in the liquid portion. This water is transported to the wastewater treatment unit 8 through pipe 9 for treatment. The wastewater treatment unit 8 is equipped with a filter to remove solid particles and suspended matter, facilitating subsequent effective utilization (e.g., the treated wastewater can be used for agricultural irrigation and to provide valuable fertilizer for agriculture and horticulture). In another example, the wastewater treatment unit 8 is connected to the composting equipment 41, and its function is similar to the wastewater treatment in the composting equipment 41; this will not be elaborated further in this application.

[0036] In some embodiments, such as Figure 1 As shown, the system also includes an intelligent control module 10, which is electrically connected to the collection mechanism 2, the separation device 3, and the processing mechanism. The intelligent control module 10 can automatically adjust the operating parameters of each mechanism. For example, it adjusts the working state of the separation device 3, controlling the movement and separation speed of the scraper 22 to improve the efficiency of cleaning feces and ensure optimal subsequent solid-liquid separation. It also adjusts the temperature, humidity, and ventilation device 411 inside the composting equipment 41 to ensure optimal microbial activity during composting and promote the degradation of organic waste. Furthermore, the intelligent control module 10 controls the working state of the heating device 423 and the stirring blades 422 inside the fermentation tank 42 to ensure fermentation temperature and mixing effect, allowing the liquid portion to fully ferment. The intelligent control module 10 not only automates and intelligently manages the entire processing system but also makes precise decisions based on real-time data, thereby improving overall processing efficiency. It also reduces the need for manual operation and intervention, enhances system stability and response speed, reduces secondary pollution from waste, and achieves true green environmental protection and resource utilization.

[0037] The working principle of the environmentally friendly poultry manure treatment system in this application is as follows: like Figures 1 to 8 As shown, poultry manure first falls from the slatted floor 11 into the cavity 13. The moving mechanism 21 on the bottom plate 12 drives the scraper 22 to move. The scraper 22 scrapes the manure on the bottom plate 12 and the slatted floor 11 and moves it toward the separation device 3, so that the manure falls into the separator 32 through the connector 31. The variable diameter spiral shaft 321 in the separator 32 can separate the solid part and the liquid part of the manure. It should be noted that the solid part of the manure includes manure particles, undecomposed organic matter, etc., while the liquid part is sewage rich in water and organic matter.

[0038] Subsequently, the solid portion of the manure enters the composting equipment 41 through the discharge port 322 and the first pipe fitting 5. The composting equipment 41 has a multi-layered structure, with adjustable partitions 410 between each layer to ensure that the solid portion ferments under suitable temperature and humidity conditions. The ventilation device 411 during the composting process ensures good ventilation, promotes microbial activity, and accelerates manure decomposition. The liquid portion of the manure enters the fermentation tank 42 through the drain port 323 and the second pipe fitting 6. Under high temperature and high humidity, the organic matter is further decomposed by the spiral stirring of the paddle 422 and the heating device 423. During this period, the biogas generated by fermentation flows into the biogas collection device 7 through the pipe 9 for collection and is used for power generation, heating, or other energy purposes. The wastewater generated in the fermentation tank 42 or the composting equipment 41 flows into the wastewater treatment facility 8 for cleaning and recycling, removing suspended solids, organic matter, nitrogen, phosphorus, and other pollutants from the wastewater to ensure that the wastewater meets the discharge standards. The treated wastewater can be used for agricultural irrigation or further recycling.

[0039] Finally, the entire system is automatically adjusted through the intelligent control module 10, which monitors various data (such as temperature, humidity, flow rate, air pressure, etc.) in real time to ensure that the operation of each link is accurate and stable, and alarms or automatic adjustments are made when a fault occurs to ensure the efficient operation of the system.

[0040] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
