Description

Technical Field

[0001] This utility model relates to the field of animal husbandry, specifically a new type of green energy and low-carbon animal husbandry shed. Background Technology

[0002] In recent years, China's beef demand has continued to grow, driven by multiple factors such as consumption upgrading, population growth, the development of the catering industry, and increased health awareness. However, my country's beef production is limited by factors such as long breeding cycles, high costs, and the fact that most cattle are raised by small-scale farmers, resulting in a supply-demand gap that relies on imports. Improving my country's beef cattle production is the primary issue to address in terms of both quantity and quality within the beef cattle farming industry.

[0003] The main advantages of livestock farming in cold regions are: suitable for beef cattle growth, abundant and nutritious forage resources, reduced risk of disease transmission, low cost and high nutritional value of silage, and better taste of beef in cold environments.

[0004] In cold regions, the main challenges in constructing livestock sheds are insulation, ventilation, and air quality. Consequently, energy consumption is higher in these areas. Currently, livestock sheds in my country rely on municipal electricity, leading to high electricity costs, a lack of real-time monitoring and optimization of electricity usage, weak emergency response capabilities, high carbon emissions, and resource waste.

[0005] The manure produced by existing carbon-based livestock farming sheds is not effectively utilized, which not only easily pollutes the environment but also easily leads to livestock diseases and affects their growth.

[0006] Therefore, it is necessary to provide a new type of green energy and low-carbon livestock breeding shed to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a new type of green energy and low-carbon livestock breeding shed.

[0008] This utility model provides a novel green energy and low-carbon livestock breeding shed, comprising a shed body built on the ground, a manure collection pipe and a mixing tank buried underground, a conveying pump and a screw extrusion solid-liquid separation device installed on the ground, and a biogas digester embedded in the ground. The ground inside the shed body is provided with a manure collection trough, and a manure scraping device for scraping manure water in the manure collection trough is installed on the inner wall of the shed body. One end of the manure collection trough is connected to the mixing tank through a manure collection pipe. The mixing tank is connected to the inlet of the screw extrusion solid-liquid separation device through a conveying pump. The liquid discharged by the screw extrusion solid-liquid separation device is connected to the biogas digester through a pipe.

[0009] Preferably, the manure scraping device includes a guide rail and a rack fixed to the inner wall of the shed. A mounting base is slidably connected to the guide rail, and a motor is fixed to the mounting base. A gear is fixed to the output end of the motor, and the gear meshes with the rack. A scraper is provided on the mounting base, and the scraper cooperates with the inner wall of the manure collection trough.

[0010] Preferably, a cylinder is fixed on the mounting base, and the scraper is fixed to the end of the piston rod of the cylinder.

[0011] The motor drives the gears to rotate forward and backward. Because the gears and racks mesh, the mounting base slides left and right along the guide rail. When the mounting base moves towards the manure collection pipe, the piston rod of the cylinder is in an extended state, which pushes the manure in the manure collection trough into the manure collection pipe. The manure collection pipe is in an inclined state and enters the mixing tank. After mixing in the mixing tank, the mixture is transported by a conveying pump to the screw extrusion solid-liquid separator for solid-liquid separation. The solid produced by the screw extrusion solid-liquid separator is used as organic fertilizer, and the wastewater produced enters the biogas digester (anaerobic digester) to produce biogas for power generation and heating. The digestive liquid produced undergoes biological treatment, and the treated water is used for irrigation.

[0012] Preferably, the ground inside the shed is sloped to facilitate the discharge of water and feces into the manure collection trough.

[0013] Preferably, the inner wall of the shed is provided with an isolation partition near the manure collection trough to isolate the animals and prevent them from entering the manure collection trough.

[0014] Compared with related technologies, the present invention provides the following beneficial effects:

[0015] Environmental benefits: Through a systematic manure treatment process, including centralized collection in manure troughs, automated cleaning by manure scraping devices, preliminary treatment in mixing tanks, solid-liquid separation by screw extrusion solid-liquid separators, and anaerobic fermentation in biogas digesters, the pollution caused by livestock farms to the environment is effectively reduced. In particular, the biogas produced through anaerobic fermentation can be used for power generation and heating, reducing dependence on traditional energy sources.

[0016] Resource recycling: Solid waste is converted into organic fertilizer, and the liquid portion is used for farmland irrigation after biological treatment, realizing the effective recycling of resources and promoting the sustainable development of agricultural production.

[0017] Improved work efficiency: Automated manure scraping devices greatly improve manure removal efficiency, reduce labor costs, and maintain hygienic conditions in the farm, which is conducive to the healthy growth of animals. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to 1- Figure 4 A new type of green energy and low-carbon livestock breeding shed is designed to achieve efficient treatment and resource utilization of livestock and poultry manure, thereby improving the environmental protection level and energy efficiency of the farm. The shed includes a shed body 1 built on the ground, a manure collection pipe 2 buried underground and a mixing tank 3, a conveying pump 4 installed on the ground and a screw extrusion solid-liquid separation device 5, and a biogas digester 6 embedded in the ground.

[0026] A manure collection trough 7 is installed on the ground inside the shed 1 to collect animal excrement. One end of the manure collection trough 7 is connected to a mixing tank 3 via an inclined manure collection pipe 2, allowing the manure to flow smoothly into the mixing tank 3 under gravity. The mixing tank 3 is connected to the inlet of a screw extrusion solid-liquid separator 5 via a conveying pump 4, which transports the uniformly mixed manure to the solid-liquid separator for processing. The solid material separated by the screw extrusion solid-liquid separator 5 can be used as high-quality organic fertilizer, while the separated liquid is transported through a pipeline to a biogas digester 6 for anaerobic fermentation to produce biogas for power generation or heating. The resulting digestate, after further biological treatment, can be used for farmland irrigation, achieving resource recycling.

[0027] To automate the cleaning of feces in the manure collection trough 7, a manure scraping device 8 is installed on the inner wall of the shed 1. The manure scraping device 8 includes a guide rail 9 and a rack 10 fixed to the inner wall of the shed 1. A mounting base 11 is slidably connected to the guide rail 9, and a motor 12 is fixedly mounted on the mounting base 11. A gear 13 is fixedly connected to the output shaft of the motor 12. The gear 13 meshes with the rack 10, thereby driving the mounting base 11 to reciprocate linearly along the guide rail 9.

[0028] A cylinder 16 is fixed on the mounting base 11, and a scraper 15 is connected to the end of its piston rod. The scraper 15 fits tightly with the bottom and side walls of the manure collection trough 7, effectively scraping away accumulated fecal water and sludge. When the motor 12 drives the gear 13 to rotate forward and backward, the mounting base 11 slides left and right along the guide rail 9. During the movement towards the manure collection pipe 2, the piston rod of the cylinder 16 is in an extended state, causing the scraper 15 to press tightly against the bottom of the manure collection trough 7 and push the feces into the manure collection pipe 2, thus realizing the automatic manure cleaning function.

[0029] In a further optimized design, the ground inside the shed 1 is arranged at a certain angle to facilitate the natural flow of feces and sewage to the manure collection trough 7, thereby improving sewage discharge efficiency.

[0030] In addition, an isolation partition 17 is provided on the inner wall of the shed near the manure collection trough 7 to prevent animals from accidentally entering the manure collection trough 7 area, ensure the normal operation of the manure scraping device 8, and at the same time ensure the safety of the animals.

[0031] In summary, the novel green energy and low-carbon livestock breeding shed provided by this utility model integrates a manure collection trough, a manure scraping device, a solid-liquid separation system, and a biogas fermentation system, thereby achieving the harmless treatment and resource reuse of manure and wastewater. It has good environmental and economic benefits and is suitable for the construction and renovation of modern large-scale and green livestock and poultry farms.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
