Description

Technical Field

[0001] This utility model relates to the field of organic solid waste resource utilization, and in particular to an adjustable diversion device for real-time control of the carbon-nitrogen ratio in organic solid waste resource utilization. Background Technology

[0002] In the resource utilization of organic solid waste, such as through pyrolysis and landfill, in order to regulate carbon and nitrogen to the ideal range, high-carbon (straw / wood chips) and high-nitrogen materials (manure / sludge) are generally dynamically separated to ensure the coordinated supply of energy (carbon source) and cell synthesis (nitrogen source) for microorganisms. At the same time, stabilizing the C / N ratio can reduce the accumulation of volatile fatty acids (VFA) and reduce the activity of host bacteria with antibiotic resistance genes. Therefore, in the resource treatment of organic solid waste, it is necessary to use a separation device to reasonably separate high-carbon and high-nitrogen materials for subsequent treatment.

[0003] However, existing organic solid waste resource recovery methods are inconvenient for material diversion, resulting in difficulties in the treatment and transportation of different organic solid wastes. Therefore, we propose an adjustable diversion device for real-time control of the carbon-nitrogen ratio in organic solid waste resource recovery, which facilitates the diversion and control of carbon and nitrogen solid wastes. Utility Model Content

[0004] In order to overcome the problem that the existing organic solid waste resource utilization process is inconvenient to separate materials, which makes the treatment and transportation of different organic solid wastes inconvenient.

[0005] The technical solution of this utility model is: an adjustable diversion device for real-time control of carbon-nitrogen ratio in the resource utilization of organic solid waste, including a feeding device and a storage hopper installed at the discharge end of the feeding device. The storage hopper is fixedly installed in a fixed support. A mixing box is set on the inner side of the fixed support below the storage hopper. A conveying device is set between the mixing box and the storage hopper. The feeding device is used to feed organic solid waste into the storage hopper for storage. There are two storage hoppers. A diversion component is set at the upper end of the fixed support between the two storage hoppers. The diversion component is used to control the sorting of organic solid waste.

[0006] Preferably, the feeding device can feed different organic solid waste materials into the storage hopper, and guide the material flow according to the opening and closing of the diversion component, so as to facilitate the real-time control of organic solid waste.

[0007] Preferably, the feeding device includes a conveyor frame, a conveyor belt is provided inside the conveyor frame, and baffles are provided on the surface of the conveyor belt for feeding organic solid waste into the storage hopper.

[0008] Preferably, the storage hopper has a funnel-shaped structure with an open top.

[0009] Preferably, the conveying device and the storage hopper correspond one-to-one. The conveying device includes a conveying pipe, inside which is a conveying auger. A motor is installed at the end of the conveying pipe to drive the conveying auger to rotate. The bottom of the conveying pipe and the storage hopper are connected. When the conveying auger rotates, it pushes the organic solid waste to move in the conveying pipe. The lower end of the conveying pipe is connected to the bottom of the mixing box.

[0010] Preferably, the mixing tank is equipped with a stirring component for mixing.

[0011] The mixing assembly includes a drive motor fixedly mounted on the surface of the mixing tank. The mixing tank is equipped with a stirring rod, and the drive motor is used to drive the stirring rod to rotate, thereby mixing the organic solid waste.

[0012] Preferably, the diversion assembly includes a first guide plate and a second guide plate. A connecting bracket is fixedly installed on the left side of the upper end of the fixed bracket. The first guide plate is rotatably installed on the right side of the upper end of the connecting bracket via a rotating shaft, and the right end of the first guide plate is adapted to the second guide plate. An installation rod is provided on the inner side of the connecting bracket. A first electric push rod is rotatably installed on the surface of the installation rod. The output end of the first electric push rod is rotatably connected to the lower end face of the first guide plate. The first electric push rod is used to drive the first guide plate to flip.

[0013] Preferably, a mounting frame is fixedly installed on the upper end of the fixed bracket. The second guide plate is rotatably installed on the inner side of the mounting frame via a rotating shaft. The second guide plate and the first guide plate have the same width. One end of the second guide plate is in contact with the first guide plate, while the other end of the second guide plate extends to the top of one of the storage hoppers to guide the fed organic solid waste into one of the storage hoppers. Second electric push rods are rotatably installed on both sides of the surface of the mounting frame. The output ends of the two second electric push rods are rotatably connected to the two ends of the second guide plate, respectively. The second electric push rods are used to drive the second guide plate to flip.

[0014] The beneficial effects of this utility model are:

[0015] 1. Organic solid waste is conveyed by a feeding device and fed into a storage hopper. During feeding, the first and second guide plates form a flow divider. When the first and second guide plates are in contact, they form a flow guide, and the organic solid waste enters one storage hopper. Under the action of an electric push rod, the guide plates flip, causing the first guide plate to flip downward and the second guide plate to flip upward, thus spreading out and allowing the organic solid waste to enter another storage hopper. This facilitates the separation of organic solid waste according to carbon and nitrogen ratio, and allows for the mixing and treatment of organic solid waste according to the carbon-nitrogen ratio, which is convenient for subsequent resource recovery treatment.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Organic solid waste can be classified into urban organic solid waste, industrial organic solid waste, and agricultural and forestry organic solid waste according to its source. Urban organic solid waste includes sewage sludge and urban domestic solid waste. According to statistics, by 2025, the annual output of urban domestic waste worldwide will reach 2.2 billion tons. Due to the large population, the annual output of urban domestic waste in my country can reach 200 million tons, and it is expected that the total amount will double by 2030. If urban domestic solid waste can be used rationally, waste disposal problems can be reduced and environmental pressure can be alleviated, turning it into a harmless resource.

[0024] Industrial organic solid waste refers to the collective term for solid and semi-solid waste containing organic matter discharged during industrial production. As of 2020, my country's annual industrial solid waste production was approximately 3.675 billion tons, of which furfural residue accounted for 3.6 to 4.5 million tons annually. Furfural residue is a byproduct of furfural production from biomass such as corn stalks, corn cobs, rice straw, and rice husks. During furfural production, the hemicellulose component in the raw materials hydrolyzes under acidic conditions to produce furfural, leaving behind most of the cellulose and lignin components to form furfural residue. Furfural residue is acidic and has a high ash content; large-scale accumulation not only wastes space but can also pollute the environment.

[0025] Agricultural and forestry organic solid waste mainly includes crop straw and forestry processing waste. It is widely used due to its zero CO2 emissions throughout its entire life cycle and can be transformed into various types of products according to market demand. Currently, my country's annual output of agricultural and forestry organic solid waste is approximately 4 billion tons, accounting for 67% of the total organic solid waste. Given the enormous quantity of organic solid waste, its rational development and utilization can effectively address environmental pollution and resource scarcity issues.

[0026] Currently, conventional treatment methods mainly include landfilling, pyrolysis, and microbial degradation. Degradation is also a form of composting. Composting is a process that transforms organic waste or plant and animal waste into a stable, nutrient-rich soil conditioner. Microorganisms play a crucial role in this process, decomposing organic matter and converting it into nutrients usable by plants. The carbon-to-nitrogen ratio (C / N) refers to the ratio of the total carbon content to the total nitrogen content in organic matter. It is usually expressed as C / N. The ratio of carbon to nitrogen in organic matter is one of the key factors for successful composting.

[0027] When the carbon-to-nitrogen ratio of composting materials is within the optimal range required for microbial growth (generally considered to be between 25:1 and 35:1), the decomposition rate of microorganisms will accelerate, the composting temperature will rise rapidly, and the composting cycle will be shortened. This is because microorganisms can efficiently utilize carbon and nitrogen sources for growth and metabolic activities.

[0028] Situations where the carbon-to-nitrogen ratio is too high or too low: If the carbon-to-nitrogen ratio is too high, microorganisms will slow down their activity due to a lack of sufficient nitrogen source, resulting in a decrease in compost temperature and a slower decomposition rate; conversely, if the carbon-to-nitrogen ratio is too low, microorganisms may over-reproduce, consuming a large amount of oxygen and generating excessive heat, causing the compost temperature to rise sharply, and even causing "compost burning".

[0029] In the field of organic solid waste treatment, aerobic fermentation technology, due to its high efficiency in resource utilization, has become a core solution to the challenges of "circular agriculture." If the carbon-to-nitrogen ratio of the raw materials is high, the growth of bacteria and other microorganisms is limited, resulting in slower organic matter decomposition and a longer fermentation process. This also leads to an excessively high carbon-to-nitrogen ratio in the finished compost. When compost is applied to the soil, it depletes the soil of nitrogen, causing nitrogen deficiency and affecting crop growth. Conversely, if the carbon-to-nitrogen ratio is too low, there is less energy available for consumption, leading to a relative surplus of nitrogen nutrients. This causes nitrogen to be converted into ammonia nitrogen and volatilize, resulting in a significant loss of nitrogen and reduced fertilizer efficiency. For example, to achieve a suitable carbon-to-nitrogen ratio, 1 / 3 to 1 / 4 of cow manure is typically added to corn stalks to achieve rapid heating.

[0030] The development of an adjustable diversion device for real-time control of the carbon-nitrogen ratio in organic solid waste resource recovery is also an automated structure for realizing the resource recovery of organic solid waste. It can adjust the proportion of different materials according to the carbon-nitrogen ratio, increasing convenience.

The storage hopper 2 is fixedly installed in a fixed support 3. The fixed support 3 has an inner... A mixing box 4 is located below the storage hopper 2. A conveying device is installed between the mixing box 4 and the storage hopper 2. The feeding device is used to feed organic solid waste into the storage hopper 2 for storage. There are two storage hoppers 2. A diversion component is installed at the upper end of the fixed support 3 between the two storage hoppers 2. The diversion component is used to control the sorting of organic solid waste. The feeding device 1 can feed different organic solid waste materials into the storage hopper 2 and guide the material according to the opening and closing of the diversion component, which facilitates the real-time control of organic solid waste.

[0032] Please see Figure 1 and Figure 2 In this embodiment, the conveying device and the storage hopper 2 correspond one-to-one. The conveying device includes a conveying pipe 5, and a conveying auger is installed inside the conveying pipe 5. A motor is installed at the end of the conveying pipe 5. The motor is used to drive the conveying auger to rotate. The bottom of the conveying pipe 5 and the storage hopper 2 are connected. When the conveying auger rotates, it pushes the organic solid waste to move in the conveying pipe 5. The lower end of the conveying pipe 5 is connected to the bottom of the mixing box 4. The conveying device receives materials from different storage hoppers 2. The conveying auger is driven by the motor to rotate. When the material enters the conveying pipe 5, it can push the material to move and send it into the mixing box 4.

[0033] Please see Figure 2 In this embodiment, the mixing tank 4 is equipped with a stirring assembly for stirring and mixing; the stirring assembly includes a drive motor fixedly installed on the surface of the mixing tank 4, and a stirring rod is provided inside the mixing tank 4. The drive motor is used to drive the stirring rod to rotate, so as to stir and mix the organic solid waste, and to mix organic solid waste with different carbon and nitrogen contents, thereby facilitating subsequent resource utilization treatment.

[0034] Please see Figure 3 . Figure 4 and Figure 5In this embodiment, the diversion assembly includes a first guide plate 6 and a second guide plate 7. A connecting bracket 61 is fixedly installed on the left side of the upper end of the fixed bracket 3. The first guide plate 6 is rotatably installed on the right side of the upper end of the connecting bracket 61 via a rotating shaft, and the right ends of the first guide plate 6 and 6 are adapted to each other. An installation rod is provided on the inner side of the connecting bracket 61. A first electric push rod 62 is rotatably installed on the surface of the installation rod. The output end of the first electric push rod 62 is rotatably connected to the lower end face of the first guide plate 6. The first electric push rod 62 is used to drive the first guide plate 6 to rotate. An installation frame is fixedly installed on the upper end of the fixed bracket 3. The second guide plate 7 is rotatably installed on the inner side of the installation frame via a rotating shaft, and the width of the second guide plate 7 is the same as that of the first guide plate 6. The first guide plate 6 and the second guide plate 7 are attached to each other, while the other end of the second guide plate 7 extends above one of the storage hoppers 2 to guide the fed organic solid waste into one of the storage hoppers 2. The two sides of the mounting frame are rotatably mounted with second electric push rods 71. The output ends of the two second electric push rods 71 ​​are rotatably connected to the two ends of the second guide plate 7 respectively. The second electric push rods 71 ​​are used to drive the second guide plate 7 to flip. The first electric push rod 62 and the second electric push rod 71 push the two guide plates respectively. When the first guide plate 6 and the second guide plate 7 are attached, a guide structure is formed. When the first guide plate 6 and the second guide plate 7 are unfolded, the first guide plate 6 flips downward and the second guide plate 7 flips upward, thereby diverting the organic solid waste.

[0035] During operation, organic solid waste is conveyed by the feeding device 1 and fed into the storage hopper 2. The two storage hoppers 2 can accommodate high-nitrogen and high-carbon materials. The first electric push rod 62 and the second electric push rod 71 push the two guide plates respectively. When the first guide plate 6 and the second guide plate 7 are in contact, they form a guide structure. When the first guide plate 6 and the second guide plate 7 are unfolded, the first guide plate 6 flips downward and the second guide plate 7 flips upward, thereby diverting the organic solid waste. The bottom of the storage hopper 2 is connected to the conveying pipe 5, so that the organic solid waste enters the storage hopper 2. The motor drives the conveying auger to rotate. When the material enters the conveying pipe 5, it can be pushed to move and sent into the mixing box 4. The high-nitrogen material and the high-carbon material are mixed in the mixing box 4 according to the appropriate carbon-nitrogen ratio, which facilitates subsequent resource recovery treatment.

[0036] Through the above steps, the feeding device 1 can feed different organic solid waste materials into the storage hopper 2, and guide the material according to the opening and closing of the diversion component, so as to facilitate the real-time control of organic solid waste. This solves the problem that in the existing organic solid waste resource treatment, it is inconvenient to divert the material, which makes the treatment and transportation of different organic solid wastes inconvenient.
