Description

Technical Field

[0001] The utility model relates to the field of organic waste regeneration, in particular to an ecological fermentation bin for rural organic waste. Background Art

[0002] In the field of rural organic waste recycling, traditional composting fermentation technologies mainly include vertical fermentation tanks and turning composting. These technologies play an important role in converting organic waste into fertilizers, but they also have some limitations and disadvantages.

[0003] The vertical fermentation tank is a common composting fermentation equipment, which promotes the decomposition of organic matter through continuous stirring and intermittent micro-oxygenation. However, this type of equipment usually requires high construction and operation costs, and may produce more odor during the fermentation process, causing pollution to the surrounding environment. The design and operation complexity of the vertical fermentation tank also leads to its high maintenance cost, requiring professional technicians to operate and maintain it. In addition, the vertical fermentation tank consumes a lot of energy during operation, resulting in high processing costs, which is not conducive to large-scale promotion and application. Today, when energy consumption and environmental protection are increasingly valued, these disadvantages of vertical fermentation tanks have gradually become a bottleneck restricting its development.

[0004] Turning composting is a more traditional composting method, which increases the supply of oxygen and promotes the activity of microorganisms by turning the composting regularly. However, this method has problems such as complex operation, long fermentation cycle, and large floor space. Turning composting needs to be turned regularly, which is complicated to operate and labor-intensive. In addition, due to uneven turning, it is easy to cause incomplete fermentation and low maturity. In addition, turning composting is easily affected by weather in an open-air environment. For example, too much rain may cause the fermentation process to be blocked, affecting the fermentation effect. In continuous rainy weather, it becomes particularly difficult to control the moisture of turning composting, which easily causes the material to be over-wet, affecting the fermentation efficiency and product quality. At the same time, turning composting is also prone to produce odor in an open-air environment, causing pollution to the surrounding environment and affecting the quality of life of surrounding residents.

[0005] In addition, composting also faces the problem of large nitrogen loss. During the fermentation process, ammonia produced by the decomposition of organic matter is easily volatilized, resulting in the loss of nitrogen. Nitrogen is an important nutrient element necessary for plant growth. Large nitrogen losses not only affect the fertilizer efficiency, but also reduce the market competitiveness of compost products. In addition, composting in an open-air environment is also susceptible to pests and diseases, resulting in a decline in the quality of the compost product and increasing the difficulty of subsequent processing.

[0006] Therefore, it is necessary to improve the equipment for recycling rural organic waste to overcome the drawbacks of the prior art. Utility Model Content

DETAILED DESCRIPTION

[0042] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the ecological fermentation bin for rural organic waste of the utility model in conjunction with the accompanying drawings.

[0043] The utility model can be applied to the regeneration of rural organic waste, and finally obtain organic fertilizer for use in agricultural production. The ecological fermentation bin for rural organic waste disclosed by the utility model solves the technical problem of incomplete fermentation in the prior art due to the difficulty of sufficient contact of organic waste with oxygen.

[0044] See also Figure 1 and Figure 2 , based on the technical problems solved above, the utility model discloses an ecological fermentation warehouse for rural organic waste, which is used to aerobic ferment the organic waste to form organic fertilizer, including a warehouse body 100, wherein the warehouse body 100 is a closed structure and has a cavity inside;

[0045] A feeding system 200 is provided at one end outside the silo 100 for uniformly conveying organic waste into the silo 100;

[0046] A discharge port 108 is provided at the bottom of the other end of the bin body 100 for discharging the organic fertilizer obtained after fermentation out of the bin body 100;

[0047] A load-bearing frame 101 is fixed in the cavity of the silo 100, and a conveying assembly is arranged in the load-bearing frame 101. The conveying assembly includes a conveyor belt 103, and the conveyor belt 103 extends in the horizontal direction. The surface of the conveyor belt 103 is used to evenly spread the organic waste. The starting end of the conveyor belt 103 is close to the feeding system 200, and the end of the conveyor belt 103 is close to the discharge port 108. The conveying assembly is used to convey the organic waste from the starting end to the end of the conveyor belt 103;

[0048] A fan 106 is disposed at the bottom of the warehouse body 100 . The fan 106 is evenly distributed below the conveyor belt and is used to provide oxygen to the interior of the warehouse body 100 , so that the interior of the warehouse body 100 is in an aerobic state.

[0049] The technical principle of this solution is: the ecological fermentation bin adopts a closed design with a cavity inside, which helps to control the fermentation environment, maintain constant temperature and humidity conditions, and reduce interference from the external climate and the escape of odor. One end of the fermentation bin is equipped with a feeding system 200. The design of this system allows organic waste to enter the fermentation bin efficiently and evenly, providing a uniform and consistent material basis for the subsequent fermentation process. A discharge port 108 is provided at the bottom of the other end of the fermentation bin to facilitate the convenient output of materials, collection and subsequent use. The conveyor belt 103 in the bin body 100 extends in a horizontal direction, and its surface is used to evenly spread the organic waste to ensure uniform fermentation and ventilation of the material throughout the fermentation process. The conveying component is driven by a motor and can convey the organic waste from the starting end of the conveyor belt 103 (close to the feeding system) to the bottom of the fermentation bin. 200) is continuously transported to the end (near the discharge port 108), realizing the orderly movement of materials in the fermentation bin. Below the conveyor belt 103, the fan 106 evenly distributed at the bottom of the bin body 100 provides necessary oxygen for the inside of the fermentation bin, ensuring the activity of aerobic microorganisms in the bin body 100 and promoting the decomposition and transformation of organic matter. Under aerobic conditions, microbial metabolic activity is vigorous, and organic matter is decomposed and transformed into stable organic fertilizer. After a period of aerobic fermentation, pathogens and weed seeds in the organic waste are eliminated, and the organic matter is transformed into nutrient-rich organic fertilizer, which can be used in agriculture, realizing the resource utilization of waste. This solution realizes the efficient treatment and resource utilization of organic waste through the above principle, and avoids the environmental problems that may occur in the traditional composting process.

[0050] Compared with the composting method commonly used in the prior art, the present solution does not require regular turning of the organic waste, thereby avoiding the disadvantages of incomplete fermentation caused by untimely or incomplete turning, and also simplifies the operating difficulty and workload of the operator. At the same time, since the entire bin body 100 is a closed structure, both the fermentation liquid and the odor generated during the fermentation process can be conveniently collected and purified, reducing the probability of odor being emitted at any time during the fermentation process or the fermentation liquid flowing crosswise.

[0051] Preferably, the conveyor belt 103 is a mesh belt with evenly distributed mesh holes, so that the air blown up from the bottom can pass through the mesh belt and fully contact the organic waste placed on the surface of the conveyor belt 103, so that the organic waste is always in an aerobic state during fermentation, which is conducive to the smooth progress of the fermentation process;

[0052] Preferably, the mesh has an aperture range of 1 to 20 mm.

[0053] Preferably, the mesh has an aperture range of 1 to 5 mm to prevent organic waste from leaking out of the mesh. In addition, a smaller aperture can provide better and more uniform air permeability, which helps aerobic microorganisms to contact the bottom of the organic waste more easily and evenly, thereby ensuring fermentation efficiency. At the same time, smaller meshes are not easily clogged, which affects the transmission efficiency.

The inner layer and the outer layer are both polyester fiber layers, and the middle layer is an e-PTFE membrane layer. The polyester fiber layer and the e-PTFE membrane layer are both microporous structures.

[0055] The molecular membrane top cover 400 is designed to improve fermentation efficiency and effectively control odor emissions without generating secondary pollution, and can ensure the stable operation of the warehouse body 100 under variable climate conditions, such as extremely cold or hot weather conditions. The top of the warehouse body is covered with a molecular membrane top cover, which achieves the dual functions of heat preservation and ventilation, can shorten the fermentation cycle and effectively reduce the generation of odor. The molecular membrane top cover has excellent air permeability and heat preservation, and can provide the most suitable conditions for aerobic composting fermentation. In addition, the molecular membrane top cover can effectively remove odors without the need for additional deodorization equipment, reducing construction and operating costs. At the same time, the molecular membrane top cover helps to preserve nitrogen, reduce nitrogen loss, and improve the fertilizer efficiency of fertilizer output.

[0103] The technical principle of this embodiment is: the ecological fermentation bin adopts a closed design with a cavity inside, which helps to control the fermentation environment, maintain constant temperature and humidity conditions, and reduce the interference of the external climate and the escape of odor. One end of the fermentation bin is equipped with a feeding system. The design of the system allows organic waste to enter the fermentation bin efficiently and evenly, providing a uniform and consistent material basis for the subsequent fermentation process. A discharge port is provided at the bottom of the other end of the fermentation bin to facilitate the convenient output of materials, collection and subsequent use. The conveyor belt in the bin extends horizontally, and its surface is used to evenly spread the organic waste to ensure uniform fermentation and ventilation of the material throughout the fermentation process. The conveying component is driven by a motor and can transport the organic waste from the starting end of the conveyor belt (close to the feeding port) to the bottom of the fermentation bin. The system) continuously transports the waste to the end (near the discharge port), realizing the orderly movement of the materials in the fermentation bin. The fans evenly distributed at the bottom of the bin below the conveyor belt provide the necessary oxygen for the fermentation bin, ensuring the activity of aerobic microorganisms in the bin and promoting the decomposition and transformation of organic matter. Under aerobic conditions, the microbial metabolism is vigorous, and the organic matter is decomposed and transformed into stable organic fertilizer. After a period of aerobic fermentation, the pathogens and weed seeds in the organic waste are eliminated, and the organic matter is transformed into nutrient-rich organic fertilizer, which can be used in agriculture, realizing the resource utilization of waste. This embodiment realizes the efficient treatment and resource utilization of organic waste through the above principle, and avoids the environmental problems that may occur in the traditional composting process.

[0104] Specifically, the ecological fermentation warehouse for rural organic waste of this embodiment can achieve the following technical indicators:

[0105] 1. Wastewater: no leachate discharge;

[0106] 2. Exhaust gas: The odor is measured by the "Three-compare odor bag method for determination of air quality odor" (GB / T14675-1993), meeting the third-level standard of the "Standard for Control of Odor Pollutants" (GB14554-1993);

[0107] 3. Solid waste (organic fertilizer): applicable to the relevant standards of "Organic Fertilizer" (NYT525-2021);

[0108] 4. Noise: Conform to Class 2 standard requirements of “Environmental Noise Emission Standards for Industrial Enterprises” GB12348-2008.

[0109] The ecological fermentation bin for rural organic waste disclosed in this embodiment realizes continuous conveying and uniform mixing of materials through the synergistic effect of multi-layer conveyor belts and crushers, provides sufficient oxygen and a suitable fermentation environment for microorganisms, thereby greatly improving the fermentation efficiency. At the same time, by utilizing the heating characteristics of the materials, the temperature of the newly input materials can be quickly increased, the decomposition of organic matter can be accelerated, and the fermentation cycle can be shortened. There is no need to regularly turn over the organic waste, thus avoiding the disadvantages of incomplete fermentation caused by untimely or incomplete turning, and also simplifies the operating difficulty and workload of the operators.

[0110] Compared with traditional vertical fermentation tanks and composting, the fermentation cycle of this equipment can be shortened by more than 50%; the use of multi-layer fermentation technology improves the utilization rate of oxygen, reduces ventilation, and thus reduces energy consumption. Compared with traditional vertical fermentation tanks, the energy consumption of this equipment can be reduced by more than 30%;

[0111] Since the entire warehouse is a closed structure and the top of the warehouse is covered with a molecular membrane cover, it achieves the dual functions of heat preservation and ventilation, which can shorten the fermentation cycle and effectively reduce the generation of odor. The molecular membrane cover has excellent air permeability and heat preservation, and can provide the most suitable conditions for aerobic composting fermentation. In addition, the molecular membrane cover can effectively remove odors without the need for additional deodorization equipment, reducing construction and operating costs. At the same time, the molecular membrane cover helps to preserve nitrogen, reduce nitrogen loss, and improve the fertilizer efficiency of fertilizer output;

[0112] This embodiment combines dynamic and static fermentation, which improves the fermentation maturity, makes the fertilizer more uniform and more harmless; this embodiment does not discharge leachate during the fermentation process, avoiding the occurrence of odor or fermentation liquid cross-flow at any time during the fermentation process; the waste gas emissions and noise during the operation of this embodiment meet the relevant environmental protection standards, and the solid waste (organic fertilizer) meets the relevant standards of "Organic Fertilizer" (NYT525-2021), realizing an environmentally friendly treatment method; in short, this embodiment has multiple technical advantages such as high fermentation efficiency, no need for additional deodorization equipment, low overall energy consumption, on-site decomposition of waste, and output of organic fertilizer, which is suitable for rural organic waste treatment applications.
