Description

Technical Field

[0001] This utility model relates to the field of crop-livestock recycling technology, and in particular to a high-efficiency fertilizer treatment system for crop-livestock recycling. Background Technology

[0002] Animal manure is a crucial raw material for organic fertilizer used in crop cultivation, embodying a cycle of crop and livestock farming. Large-scale livestock farms, such as large chicken farms, typically have many identical or different standard feeding units, generating enormous amounts of manure daily. To address issues like excessive bacteria or high humidity, current technologies often pre-treat collected manure by mixing, crushing, and heating it in a mixing and crushing device before composting to produce organic fertilizer for crops. However, this mixing and heating equipment has extremely limited capacity, and the subsequent composting process is lengthy, failing to meet the massive manure processing requirements of large-scale livestock farms. Therefore, it is necessary to develop a treatment system that significantly improves equipment utilization and processing efficiency, shortens the subsequent composting cycle, and, most importantly, adapts to the specific conditions of standard feeding units in livestock farms. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency fertilizer treatment system for crop-livestock cycles.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency fertilizer treatment system for crop-livestock cycles includes: At least one pair of standard feeding units, each of which is equipped with a manure discharge section, and the manure discharge sections of the pair of standard feeding units are arranged opposite to each other; A pair of mixing and crushing machines, matched with the pair of standard feeding units, are located near the manure discharge section of the corresponding standard feeding unit, and are used to receive the manure discharged from the manure discharge section and mix and crush it. A rotary mixing tank, located below ground level between the pair of standard feeding units, is used to receive manure from the pair of mixers and crushers and to continuously mix it with fermentation additives. A rotary fermenter, located on the ground between the pair of standard feeding units, is used to receive manure from the rotary mixing tank and perform continuous pre-fermentation treatment.

[0005] The efficient fertilizer treatment system for crop-livestock cycle described above is further characterized in that a feed inlet is provided above the mixing and crushing machine, and the manure discharged from the manure discharge section is fed to the mixing and crushing machine from the feed inlet above the mixing and crushing machine through the first material guide section.

[0008] The efficient fertilizer treatment system for crop-livestock cycle described above is further characterized in that each of the pair of mixing and crushing machines has a discharge port at its bottom, and the front end of the rotary mixing tank has an upward-facing inlet. The manure discharged from the discharge ports of the pair of mixing and crushing machines is fed to the inlet of the rotary mixing tank through the second guide section.

[0009] The efficient fertilizer treatment system for crop-livestock cycle described above is further characterized in that the top of the feed inlet of the rotary mixing tank is not higher than the ground, and the second material guide is arranged at an angle from below the discharge port of the mixing crusher to above the feed inlet of the rotary mixing tank.

[0016] Figure 2 This is a schematic diagram of the efficient fertilizer treatment system for crop-livestock recycling according to this utility model, within the entire crop-livestock recycling system.

[0017] The components represented by the labels in the diagram are: 1. Standard feeding unit; 2. Mixing and crushing machine; 3. Rotary mixing tank; 4. Rotary fermentation tank; 5. Composting device; 6. Manure discharge section; 7. First feeding section; 8. Second feeding section; 9. Lifting conveyor. Detailed Implementation

[0018] Exemplary embodiments of this disclosure will now be described in more detail.

[0019] Example 1 like Figure 1 The above describes a high-efficiency fertilizer treatment system for crop-livestock cycles, comprising: At least one pair of standard feeding units 1, each of which is equipped with a manure discharge section 6, and the manure discharge sections 6 of the pair of standard feeding units 1 are arranged opposite to each other. The standard feeding unit 1 in this embodiment is a standardized layer hen house in the prior art, equipped with a belt-type manure collection device, which can discharge manure through an auger device or a manure discharge pipe, that is, the manure in the manure discharge section 6 can come from the existing auger device or manure discharge pipe.

[0020] The system includes a pair of mixing and crushing machines 2 that are matched with the pair of standard feeding units 1. They are located near the manure discharge section 6 of the corresponding standard feeding unit 1 and are used to receive the manure discharged from the manure discharge section 6 for mixing and crushing. In this embodiment, the mixing and crushing machine 2 is a non-heated horizontal mixing and crushing machine. A twin-shaft mixer is selected from the market. The horizontal mixing and crushing machine without heating function is selected to receive fresh chicken manure sent from the manure discharge section 6. Its main function is to crush and disperse the clumps of wet manure and perform preliminary homogenization.

[0021] from Figure 1 As can be seen, a first feeding section 7 is installed below the manure discharge section 6 of the standard feeding unit 1, and a feed inlet is opened above the mixing and crushing machine 2. The manure discharged from the manure discharge section 6 is fed to the mixing and crushing machine 2 from the feed inlet above the mixing and crushing machine 2 through the first feeding section 7.

[0022] The first feeding section 7 can also be installed on the ground, as long as its position is below the manure discharge section 6 of the standard feeding unit 1 and can guide the material to the mixing and crushing machine 2. The first feeding section 7 can guide the material by its own inclination and the weight of the manure without the need for additional power.

[0023] The system includes a rotary mixing tank 3. Figure 1 What we see is the direction of the circular cross-section. Figure 2 The diagram shows its length direction. It is located below ground level between the pair of standard feeding units 1 and is used to receive manure from the pair of mixing and crushing machines 2 and to continuously mix it with fermentation auxiliary materials such as straw, sawdust, and rice husks.

[0024] The market product corresponding to rotary mixing tank 3 is a rotary mixing machine. Select equipment with internal lifting plates and auxiliary heating components. The throughput is selected according to the amount of manure in the standardized chicken house. Selecting equipment with internal lifting plates is to facilitate the thorough mixing of manure with fermentation auxiliary materials added by the feeding vehicle (such as a small loader) during the rotation process. Selecting equipment with jacketed or contact auxiliary heating components is to effectively kill pathogens during the mixing and transportation process, and to reduce the moisture content of the mixture to a suitable level for pre-fermentation, such as below 60%.

[0025] Steam jackets are a preferred and more energy-efficient auxiliary heating component, but if the breeding base cannot be equipped with a boiler system, contact heating such as hot air heating can also be selected.

[0026] This patent removes the heating function from multiple dispersed mixing and crushing machines 2 and concentrates it in the rotary mixing tank 3, which simplifies the structure of the mixing and crushing machine 2, reduces its manufacturing cost and failure rate, and at the same time, centralized heating can improve thermal energy utilization efficiency and reduce energy consumption.

[0027] like Figure 1 As shown, each of the pair of mixing and crushing machines 2 has a discharge port at its bottom, and the rotary mixing tank 3 has an upward-facing inlet at its front end. The manure discharged from the discharge ports of the pair of mixing and crushing machines 2 is fed into the inlet of the rotary mixing tank 3 through the second guide section 8. Figure 1 As can be seen, the rotary mixing tank 3 of this patent is positioned below the ground between a pair of standard feeding units 1 in order to make full use of the advantages of space and gravity. The top of the feed inlet of the rotary mixing tank 3 is also not higher than the ground, which allows the second guide section 8 to be arranged at an angle from below the discharge port of the mixing crusher 2 to above the feed inlet of the rotary mixing tank 3.

[0028] The second feeding section 8 can rely on gravity feeding or be arranged as a powered conveyor belt. In some other embodiments, there may be more standard feeding units 1 (e.g., four) using the same rotary mixing tank 3, which may be more suitable for transporting manure by a powered conveyor belt due to the lengthened manure transport path.

[0029] The system includes a rotary fermenter 4, similarly Figure 1 What we see is the direction of the circular cross-section. Figure 2 The diagram shows its length. Rotary fermenters, also called fermentation drums, are equipped with ventilation and oxygen supply systems. In this patent, they receive manure treated by rotary mixing tank 3 and perform continuous pre-fermentation. The material rotates at low speed within the tank, undergoing continuous pre-fermentation under the action of aerobic microorganisms. The temperature can be maintained at 55-65℃, achieving preliminary degradation of organic matter. Its processing capacity matches that of rotary mixing tank 3. From Figure 1 As can be seen, the rotary fermenter 4 is set on the ground between a pair of standard feeding units 1, combined with Figure 1 and Figure 2 Understandable, Figure 1 In the middle, the end of the blocked rotary mixing tank 3 is close to the front end of the rotary fermentation tank 4, but there is a height difference between the two. That is to say, the end of the rotary mixing tank 3 has a discharge port that is lower than the ground, and the front end of the rotary fermentation tank 4 has a feeding port with the opening facing upward. Therefore, the manure discharged from the discharge port of the rotary mixing tank 3 needs to be fed to the feeding port of the rotary fermentation tank 4 by a lifting conveyor 9. The lifting conveyor 9 can be a known screw conveyor or conveyor belt.

[0030] The principle of this patent is to utilize the layout of paired standard feeding units 1 on-site, and to set up an independent mixing and crushing machine 2 for each standard feeding unit 1 for preliminary treatment, thereby dispersing the pretreatment pressure. Subsequently, a high-capacity rotary equipment is used for centralized mixing and pre-fermentation, thus forming a continuous production line. This meets the needs of large-scale breeding bases with large output of manure and urgent treatment. By using a rotary mixing tank 3 and a rotary fermentation tank 4, continuous or semi-continuous feeding and discharging of materials can be achieved, reducing waiting time, greatly improving equipment utilization and processing efficiency, and shortening the overall production cycle from manure to fertilizer.

[0031] Each component of this patent can be selected from existing mature equipment. The processing capacity can be designed based on the amount of manure produced by the standardized feeding unit 1. Assuming that each standard feeding unit 1 produces about 5 tons of manure per day, if the two mixing and crushing machines 2 are selected with a processing capacity of 2.5 tons / hour, the manure can be processed in less than 2 hours. If the rotary mixing tank 3 is selected with a processing capacity of 6-8 tons / hour, considering the weight of auxiliary materials, the mixing and heating can be completed in as little as 2 hours. If the rotary fermentation tank 3 is selected with a processing capacity of 6-8 tons / hour, it can operate continuously and process one batch of materials per day.

[0032] Example 2 As can be seen from the principle described in Example 1, the rotary mixing tank 3 and the rotary fermentation tank 4 are designed to reduce the subsequent composting fermentation cycle. Therefore, as Figure 2 As shown, this embodiment provides a complete crop-livestock cycle system including the processing system of Embodiment 1. It can be seen that the organic fertilizer made from chicken manure undergoes final composting in the composting device 5 before leaving the factory or returning to the field. The composting device 5 is used to receive the material processed by the rotary fermentation tank 4.

[0033] The most common composting device 5 is a fermentation tank structure, and multiple devices are usually installed in large-scale breeding bases. The solution in this patent adds efficient pre-fermentation in the rotary fermentation tank 4, and the composting device 5 is in the final stage of decomposition, which can shorten the fermentation cycle of the subsequent composting device 5. This stage can also use traditional forced ventilation dynamic composting or even static composting.

[0034] The composting device 5 can be located near the rotary fermenter 4 and equipped with an auger, conveyor belt, etc. for material transfer, or it can be located elsewhere and fed by a feeding vehicle.

[0035] It should be noted that the treatment examples based on standardized layer hen houses listed in this patent are merely typical examples to more fully disclose the solution of this patent, and are not intended to limit this patent. Based on the embodiments described in this application, those skilled in the art can flexibly design conventional equipment selection and capacity matching according to the specific livestock species (pigs, cattle, sheep, etc.) and manure production. Therefore, the above embodiments are only a few preferred implementations of this utility model, and the scope of protection of this utility model patent should be determined by the appended claims.
