Description

Technical Field

[0001] This utility model relates to the field of composting technology, and in particular to an animal manure composting device. Background Technology

[0002] Animal manure composting is an important technology for treating livestock waste and achieving resource recycling. In existing technologies, composting devices typically employ static composting or mechanical turning methods, converting manure into organic fertilizer through natural fermentation or artificial assistance. Some devices are equipped with stirring mechanisms to promote material mixing, while others incorporate aeration systems to provide oxygen and support aerobic microorganisms in decomposing organic matter. Furthermore, some advanced equipment uses heating devices to regulate composting temperature and accelerate the fermentation process. These devices are widely used in livestock farms and organic agriculture, effectively reducing environmental pollution from manure and producing organic fertilizer suitable for farmland. However, existing composting devices still have certain limitations in terms of structural design and functional integration, making it difficult to fully meet the demands for high efficiency, environmental protection, and automation.

[0003] The shortcomings of existing composting equipment are mainly reflected in the following aspects: First, the mixing mechanism is simply designed, making it difficult to achieve uniform mixing of materials, resulting in low fermentation efficiency; second, the ventilation system is mostly simple ventilation, leading to uneven oxygen distribution and affecting the aerobic fermentation effect; third, the temperature control capability is insufficient, especially in low-temperature environments, resulting in a longer composting cycle; in addition, existing equipment generally lacks effective odor control, and secondary pollution is easily generated during exhaust; finally, the degree of automation is low, requiring more manual intervention, increasing operational complexity and labor costs. These shortcomings limit the application effect of composting equipment in large-scale farms, and there is an urgent need for a solution that integrates efficient mixing, precise temperature control, and environmentally friendly exhaust. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an animal manure composting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An animal manure composting device includes a composting bin, which is a cylindrical structure with a flat bottom and four legs. The top of the bin is an open interface with a hinged top cover. A stirring mechanism is rotatably mounted at the bottom of the bin, including a rotating shaft with spiral stirring blades arranged sequentially from top to bottom. A temperature sensor is also embedded in the shaft. An air injection mechanism is fixed to the inner wall of the bottom of the bin, including an annular pipe with several first exhaust ports evenly spaced on its top surface. One end of the annular pipe is closed, and the other end has a connecting part. The device also includes several heating plates attached to the inner wall of the bin and a second exhaust port located on the upper part of the outer wall of the bin.

[0007] Preferably, the bottom end of the mixing mechanism passes through a sealed bearing, which is located at the center of the bottom of the compost bin. A driven pulley is fixedly installed at the bottom end of the mixing mechanism. The driven pulley drives the driving pulley through a transmission belt. The driving pulley is fixed to the power output end of the motor, and the motor is fixed to the outer wall of the compost bin.

[0008] Preferably, it also includes an air pump, the exhaust end of which is connected to a high-pressure pipe, the end of which is connected to an interface, the interface being disposed through the outer wall of the compost bin, and the end of the interface engaging with a connecting part.

[0009] Preferably, the interior of the second exhaust port is provided with several activated carbon filter plates.

[0010] Preferably, it also includes a controller disposed on the outer wall of the compost bin, the controller being electrically connected to a temperature sensor, a heating plate, a motor, and an air pump.

[0011] Preferably, a matching latch is installed between the compost bin and the top cover.

[0012] This utility model has the following beneficial effects:

[0013] 1. This device significantly improves the composting efficiency of animal manure through the synergistic action of the stirring mechanism, aeration mechanism, and heating plate. The spiral stirring blades ensure uniform mixing of materials, promoting full contact between aerobic microorganisms and manure; the annular pipe design of the aeration mechanism delivers oxygen evenly through multiple primary exhaust ports, optimizing the aerobic fermentation environment; the heating plate, fitted against the inner wall, provides stable heat, maintains a suitable fermentation temperature, and shortens the composting cycle. Temperature sensors monitor in real time and the controller automatically adjusts the operating status of each component, avoiding temperature fluctuations during fermentation. This multi-functional integrated design makes the composting process more efficient, particularly suitable for small and medium-sized farms to quickly process manure and produce high-quality organic fertilizer.

[0014] 2. This device features an activated carbon filter screen built into the second exhaust port, effectively adsorbing odorous gases such as ammonia and sulfides generated during composting, significantly reducing environmental pollution. The interlocking design between the top cover and the compost bin ensures a tight seal, preventing gas leakage and further reducing odor diffusion. The aeration mechanism provides a stable supply of oxygen via a high-pressure air pump, promoting aerobic fermentation and reducing the malodorous gases produced by anaerobic decomposition. The controller's precise control of ventilation and exhaust makes waste gas emissions more manageable. This environmentally friendly design not only improves the environmental quality around the farm but also meets the requirements of modern agriculture for green and sustainable development, making it suitable for use in environmentally sensitive areas.

[0015] 3. This device is equipped with a controller, electrically connected to a temperature sensor, heating plate, motor, and air pump, enabling automated management of the composting process. The temperature sensor monitors the compost temperature in real time, and the controller automatically adjusts the heating plate power, stirring frequency, and aeration rate based on the data, eliminating the need for frequent manual intervention. The interlocking top cover and stable support structure simplify material feeding and equipment maintenance. The automated design reduces manual monitoring and operating costs, improves the stability and reliability of equipment operation, and is particularly suitable for farms or ranches with limited labor resources, significantly enhancing the convenience and economic benefits of composting.
