Description

Technical Field

[0001] This invention belongs to the technical field of biotransformation and resource recycling, specifically, it relates to an apparatus for producing feed based on livestock and poultry manure. Background Technology

[0002] With the rapid development of livestock and poultry farming, the treatment and resource utilization of livestock and poultry manure has become a key issue for environmental protection and sustainable development. Black soldier fly larvae, due to their highly efficient bioconversion capabilities, have shown great potential in converting livestock and poultry manure into high-value feed ingredients.

[0003] While solid waste resource utilization technologies, such as pyrolysis and gasification methods for mixed urban and rural solid waste, or thermal washing and separation methods for oily solid waste, have achieved certain results in their respective fields, they have significant limitations when applied to the specific scenario of black soldier fly larvae converting livestock and poultry manure. These technologies generally suffer from complex processes, high equipment investment costs, and high energy consumption. More importantly, their core designs are mostly physical or chemical treatment processes, failing to effectively integrate and support the biotransformation mechanism of black soldier fly larvae. Furthermore, these solutions often fail to fully consider the high water content and high organic matter content of livestock and poultry manure, resulting in deficiencies in conversion efficiency, system integration, and ease of operation. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention provide an apparatus for producing feed based on livestock and poultry manure, which has the advantage of high conversion rate of livestock and poultry manure.

Detailed Implementation

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] like Figures 1-3 As shown, the apparatus for producing feed based on livestock and poultry manure according to an embodiment of the present invention includes: a crushing component 1, a conveying component 2, a biochemical component 3, and a separation component 4.

[0024] The crushing assembly 1 includes a crushing chamber 11 and a crushing component 12. The crushing component 12 includes a first clamping plate 121, at least a portion of which is disposed within the crushing chamber 11 and is movable along the length of the crushing chamber 11 for crushing livestock and poultry manure clumps. The conveying assembly 2 includes a driving component 21 and a conveying component 22, which are connected to each other. The conveying component 22 has a conveying inlet and a conveying outlet. The crushing chamber 11 is connected to and movable relative to the conveying component 22, and communicates with the conveying inlet. The biochemical assembly 3 is connected to the conveying outlet and has a biochemical chamber 31 in which livestock and poultry manure undergoes biotransformation treatment. The separation assembly 4 is connected to the biochemical assembly 3 and is used to separate larvae from residues in the livestock and poultry manure.

[0025] Specifically, such as Figures 1-3 As shown, the crushing chamber 11 is the initial processing unit of the entire device. It is located at the front end or input of the system and can directly receive the raw livestock manure blocks to be processed. A portion of the first clamping plate 121 can be installed inside the crushing chamber 11 to directly apply force to the manure blocks entering the chamber, causing them to be crushed and fall directly into the crushing chamber 11. The driving mechanism of the first clamping plate 121 (such as a hydraulic cylinder or a motor-driven linkage) can be located outside the crushing chamber 11 or integrated into the chamber structure.

[0026] The outlet of the crushing chamber 11 can be connected to the inlet of the conveying component 22 via a hinge or rotary joint, allowing for a certain angle of oscillation. Alternatively, a hose, bellows, or elastic sealing sleeve can be used for connection to absorb vibration and displacement. The crushing chamber 11 can be mounted on a guide rail or slide rail, allowing for small-amplitude linear movement or adjustment relative to the fixed conveying component 22 in the left-right direction to improve the flowability of manure blocks and prevent manure blocks from clogging the conveying inlet.

[0027] The biochemical chamber 31 is used to receive materials from the conveying outlet. Depending on the actual working conditions, mechanisms such as ventilation, temperature and humidity control, and fabric thickness adjustment can be installed in the biochemical chamber 31 to ensure that the internal environment (temperature, humidity, oxygen) is most suitable for larval growth and efficient conversion of organic matter.

[0028] Separation component 4 is connected to the outlet of biochemical chamber 31 and is the terminal equipment for separating insect residue. Separation component 4 (such as a vibrating screen or air classifier) ​​can separate larvae and residue with high purity, obtaining clean larvae as feed raw materials, while collecting residue as organic fertilizer, realizing the maximization and high-value utilization of resources, making the device a complete closed-loop system from raw material input to the output of two products (insect bodies and residue).

[0029] The apparatus for producing feed from livestock and poultry manure in this invention employs a movable clamping plate for compression crushing, solving the problem of clumping in highly moist and viscous manure and creating suitable physical conditions for subsequent bioconversion. The conveying design ensures continuous and stable material transport from pretreatment to the conversion core, laying the foundation for automated operation. The biochemical chamber 31 provides an optimized growth environment for black soldier fly larvae, improving the efficiency of converting organic matter in manure into insect protein.

[0030] In some embodiments, the crushing component 12 includes a crushing drive (not shown in the figure), and there are two first clamping plates 121. The two first clamping plates 121 are arranged at intervals along the length direction of the crushing chamber 11. The crushing drive is connected to at least one of the two first clamping plates 121 to drive the first clamping plate 121 to move.

[0031] Specifically, such as Figures 1-3 As shown, the two clamping plates are spaced apart in the left-right direction, enabling more uniform and multi-point crushing of livestock and poultry manure clumps. The crushing drive is connected to at least one clamping plate and can drive the movement of one or both clamping plates as needed, achieving flexible pressure adjustment and crushing mode switching.

[0032] Understandably, single-clamp crushing can easily cause localized stress concentration, while a double-clamp arrangement can evenly divide and crush large pieces of manure in stages, effectively preventing uncrushed pieces from entering subsequent stages. By adjusting the clamp spacing and movement amplitude, it can adapt to manure with different moisture contents and cohesiveness, enhancing the device's adaptability to different raw materials.

[0033] Furthermore, the synergistic effect of the double clamps creates a combined shearing and compression crushing mechanism within the crushing chamber 11, effectively breaking down the clump structure of highly moist and viscous fecal matter and significantly reducing the risk of material blockage at the conveying inlet. Combined with the movable connection design between the crushing chamber 11 and the conveying component 22 in the previous embodiment, this embodiment further enhances the stability and smoothness of the system during continuous operation.

[0034] In some embodiments, the crushing assembly 1 further includes a second clamping plate 122. There are two second clamping plates 122, which are arranged at intervals along the length of the crushing chamber 11. The second clamping plates 122 are connected to the inner peripheral wall of the crushing chamber 11 and are movable relative to the crushing chamber 11. The second clamping plates 122 are located below the first clamping plate 121. A crushing zone is defined between the two second clamping plates 122 along the length of the crushing chamber 11. The crushing zone is connected to the conveying inlet. A plurality of crushing spikes 124 are provided on the side of the second clamping plate 122 adjacent to the crushing zone.

[0035] Specifically, such as Figures 1-3 As shown, the first clamping plate 121 and the second clamping plate 122 form a two-layer crushing structure above and inside the crushing chamber 11. The two first clamping plates 121 perform preliminary compression crushing, while the two second clamping plates 122 perform fine crushing. In other words, the upper first clamping plates 121 perform preliminary compression of large pieces of manure, breaking down the main clump structure. The lower second clamping plates 122, with their spiked design, perform fine crushing of the material, ensuring uniform particle size of the output. This staged crushing method is more adaptable to manure raw materials with different hardness and moisture content than single-stage crushing.

[0036] Furthermore, the spiked structure can effectively pierce and tear highly viscous fecal clumps, solving the problem of slippage when traditional flat clamps are used to handle wet and sticky materials. The localized high-pressure points created by the spikes can disrupt the surface tension of the fecal clumps, reducing the adhesion of the material to the clamp surface.

[0037] In some embodiments, the crushing component 12 further includes an elastic element 123. The elastic element 123 is connected between the crushing chamber 11 and the second clamping plate 122 along the length direction of the crushing chamber 11. The crushing chamber 11 is movable along the length direction of the crushing chamber 11 so as to drive the second clamping plate 122 to reciprocate along the length direction of the crushing chamber 11 under the elastic action of the elastic element 123.

[0038] Specifically, such as Figures 1-3 As shown, the elastic element 123 is connected between the crushing chamber 11 and the second clamping plate 122. The movement of the crushing chamber 11 is transmitted to the second clamping plate 122 through the elastic element 123. Under the action of elasticity, the second clamping plate 122 moves back and forth along the length of the crushing chamber 11 to form a dynamic crushing zone with elasticity.

[0039] Understandably, when encountering exceptionally large or hard clumps of manure, the elastic element 123 provides cushioning to prevent overload damage to the equipment. Furthermore, it automatically adjusts the crushing pressure based on material resistance to avoid insufficient pressure or excessive compression. The dynamic changes in the gap between the crushing zones during reciprocating movement adapt to the passage requirements of materials with different particle sizes.

[0040] In other words, the impact force generated by the reciprocating movement of the crushing chamber 11 is more effective than static pressure in crushing. The dynamic movement allows the crushing spikes 124 to act on the material from different angles, improving the thoroughness of crushing. The reciprocating motion helps to shake off the material adhering to the clamps and spikes, reducing blockage.

[0041] In some embodiments, the apparatus for producing feed based on livestock and poultry manure according to the present invention further includes a screening component 5, which includes a screening chamber 51 and a filter screen 52. The filter screen 52 is installed in the screening chamber 51, and the screening chamber 51 is connected to the conveying outlet and the biochemical chamber 31.

[0042] Specifically, such as Figures 1-3 As shown, the screening chamber 51 is located between the outlet of the conveying assembly 2 and the inlet of the biochemical chamber 31. A filter screen 52 is installed inside the screening chamber 51 as the core screening element. The screening chamber 51 is connected to both the conveying outlet and the biochemical chamber 31, forming a necessary passage for materials and adding a fine screening step between crushing and biochemical treatment.

[0043] Understandably, the filter screen 52 can precisely control the particle size range of the material entering the biochemical chamber 31, effectively screen out excessively large particles or uncrushed impurities that may be generated during the crushing process, and ensure that the particle size of the material entering the biochemical conversion stage is uniform.

[0044] The screened materials form a loose and uniform fermentation substrate, which is conducive to the activity and feeding of black soldier fly larvae. The uniform particle size ensures uniform ventilation in the biochemical chamber 31 and avoids local hypoxia. The consistent thermal conductivity of the screened materials is beneficial for precise temperature control.

[0045] Of course, by changing the filter screen with different pore sizes according to the different characteristics of manure, the process can be flexibly adjusted. The screening process can serve as an important monitoring point for the material state, ensuring the screening effect and providing early assurance for the quality of subsequent biochemical conversion.

[0046] In some embodiments, the filter screen 52 is inclined in the height direction of the screening chamber 51, and the filter screen 52 divides the screening chamber 51 into a first chamber and a second chamber. The first chamber is located above the second chamber. The screening assembly 5 has a discharge port 53, which is connected to the first chamber and the second chamber is connected to the biochemical chamber 31.

[0047] Specifically, such as Figures 1-3 As shown, the filter screen 52 is installed at an angle and divides the screening chamber 51 into an upper first chamber and a lower second chamber. The inclined screen surface, combined with gravity, promotes the material to slide naturally down the screen surface. Compared with a horizontal screen surface, the inclined arrangement provides a longer effective screening distance. The material sliding process generates a cleaning effect on the screen surface, reducing clogging.

[0048] Understandably, the first chamber collects large particles that fail to pass through the filter screen 52 and discharges them from the system through the discharge port 53 or returns them to the upstream section for further processing. The second chamber collects qualified fine materials and directly conveys them to the biochemical chamber 31, achieving real-time separation and diversion of unqualified and qualified materials.

[0049] In some embodiments, the biochemical component 3 further includes a stirring member, at least a portion of which is disposed within the biochemical chamber 31. The biochemical chamber 31 has a reagent inlet for spraying microbial agents into the biochemical chamber 31 to allow livestock and poultry manure to ferment within the biochemical chamber 31.

[0050] Understandably, at least part of the stirring component is located within the biochemical chamber 31, allowing for direct mechanical stirring of the livestock and poultry manure within the chamber. The biochemical chamber 31 is equipped with a dedicated reagent inlet for precise spraying of microbial agents. Through stirring and agent addition, the livestock and poultry manure undergoes controlled fermentation within the biochemical chamber 31, providing pre-treated organic matter for black soldier fly larvae.

[0051] The stirring components ensure uniform distribution of microbial agents, manure, temperature, and humidity, preventing insufficient or excessive fermentation in certain areas and improving fermentation consistency and efficiency. The reagent inlet allows for targeted spraying of microbial agents, controlling agent concentration and timing of addition, enhancing the controllability and specificity of fermentation. Microbial agents (such as cellulose-decomposing bacteria and protein-decomposing bacteria) can rapidly degrade complex organic matter in manure, converting it into nutrients easily absorbed by black soldier fly larvae, thus increasing the rate of subsequent biotransformation.

[0052] In some embodiments, the apparatus for producing feed based on livestock and poultry manure in this invention further includes an air collection component 6, which includes a fan 61 and an air collection chamber 62. The fan 61 is connected to the air collection chamber 62, and the air collection chamber 62 is connected to the biochemical chamber 31 for introducing oxygen or air into the biochemical chamber 31.

[0053] Specifically, such as Figures 1-3 As shown, the gas collection assembly 6 is a complete gas supply unit consisting of a fan 61 and a gas collection chamber 62. The gas collection chamber 62 is directly connected to the biochemical chamber 31, establishing a stable gas channel. The fan 61 actively supplies oxygen or air to the biochemical chamber 31, thereby achieving controllable adjustment of the oxygen concentration within the biochemical chamber 31.

[0054] Understandably, by controlling the ventilation volume and frequency through the blower 61, the optimal dissolved oxygen concentration is maintained in the biochemical chamber 31. Sufficient oxygen supply enhances the metabolic activity of aerobic microorganisms (including added inoculants and natural microorganisms). Under aerobic conditions, the decomposition rate of organic matter is significantly higher than that under anaerobic conditions, thus shortening the fermentation cycle.

[0055] In other words, black soldier fly larvae require sufficient oxygen for normal growth and development. Introducing gas creates micro-airflows within the manure substrate, improving pore ventilation. This gas flow helps to evenly distribute temperature and humidity within the chamber. Furthermore, ventilation parameters can be adjusted based on factors such as fermentation stage, material characteristics, and larval density. The blower 61 can be linked with temperature, humidity, and oxygen sensors for automatic control, supporting flexible switching between different ventilation strategies (continuous ventilation, intermittent ventilation, etc.).

[0056] In some embodiments, the separation component 4 includes a separation chamber 41 and a temperature control component 42. The separation chamber 41 is connected to the biochemical chamber 31, and at least a portion of the temperature control component 42 is disposed within the separation chamber 41 for monitoring and controlling the temperature within the separation chamber 41.

[0057] Specifically, such as Figures 1-3 As shown, the separation chamber 41 is directly connected to the biochemical chamber 31, ensuring continuous flow of materials from biochemical conversion to separation. At least part of the temperature control component 42 is located within the separation chamber 41, enabling real-time temperature monitoring and active control. The temperature control component 42 can be a temperature sensor, heating / cooling elements, etc., forming a complete temperature management system.

[0058] Understandably, black soldier fly larvae are sensitive to temperature. A suitable temperature (e.g., 25-30°C) maintains their activity, making them easier to separate from residue and improving separation speed and purity. Temperature control prevents excessively high or low temperatures during separation, which could lead to larval death or stress, ensuring the larvae's activity and nutritional value as feed. Temperature control also regulates the viscosity and flowability of residue, reducing adhesion to separation equipment (such as vibrating screens) and improving separation efficiency.

[0059] In other words, the temperature control component 42 continuously monitors the temperature inside the separation chamber 41 and automatically adjusts it according to the set parameters, reducing manual intervention and improving process stability. The temperature settings can be dynamically optimized based on material characteristics (such as moisture content and residue amount) and environmental changes, enhancing the system's adaptability to different operating conditions.

[0060] In some embodiments, the gas collection chamber 62 is connected to the separation chamber 41 for introducing oxygen or air into the biochemical chamber 31.

[0061] Understandably, the gas collection chamber 62 is not only connected to the biochemical chamber 31, but also to the separation chamber 41. The same gas supply system serves the two key links of biochemical conversion and separation, reducing independent components and improving the compactness and synergy of the equipment.

[0062] The heat generated by the temperature control of the separation chamber 41 can be transferred to the biochemical chamber 31 through gas flow, reducing additional heating energy consumption. Gas circulation helps to homogenize the temperature distribution of the entire system and avoid local overheating or undercooling.

[0063] In other words, oxygen is continuously supplied from the biochemical transformation to the separation stage to ensure the survival and vitality of black soldier fly larvae throughout the process. Fresh air is introduced into the separation chamber 41 to dilute any harmful substances such as ammonia that may be generated. Through a unified gas management system, the stability of parameters such as oxygen concentration and humidity within the system is maintained.
