Description

Technical Field

[0001] This invention relates to the field of agricultural waste treatment technology, and in particular to an animal manure fermentation device and fermentation method. Background Technology

[0002] During the livestock breeding process, a large amount of animal manure is generated. If it is discharged directly without treatment, it will not only cause serious pollution to the soil, water and air, but also easily breed bacteria and pests, affecting the surrounding environmental sanitation and the biosecurity of the farm. In order to achieve the harmless and resource utilization of livestock and poultry manure, fermentation technology is usually used to convert manure into organic fertilizer.

[0003] In practice, some problems still exist: 1. Existing animal manure fermentation devices typically use direct feeding or simple conveying methods to transport materials from the storage bin to the crushing device or fermentation tank during the material feeding stage. Due to the lack of a stable quantitative control mechanism, the material supply is prone to fluctuations, leading to a decrease in the uniformity of subsequent crushing and fermentation processes, which affects the fermentation quality. At the same time, some devices have bidirectional transmission problems in the feeding structure. In addition, the capacity adjustment function of the feeding mechanism in the existing technology is relatively simple, and it cannot flexibly change the single feeding amount according to different fermentation needs. This can easily lead to over- or under-feeding when processing animal manure with high moisture content or high fiber content, reducing the adaptability and stability of the device.

[0004] 2. Existing animal manure fermentation devices often use screw conveyors or belt conveyors to transport materials to the crushing device. Since these conveying methods are mostly continuous, they lack precise coordination with the feeding rhythm, which can easily cause accumulation at the feed inlet or insufficient feeding, thus affecting crushing efficiency and stability. At the same time, at the crushing device or feed inlet, the material is prone to adhere to the feed channel or crushing chamber inlet due to its high moisture content and strong viscosity, forming accumulation and blockage. Existing technologies mostly rely on manual knocking or vibration devices to clear the blockage, which not only increases the labor intensity but may also cause equipment damage due to improper operation. In addition, some anti-blocking mechanisms require an additional power source to drive them. Summary of the Invention

[0014] The storage tank is equipped with an auxiliary fermentation mechanism, which includes a sealed gas tank, a one-way valve, a push rod, a connector, a ball bearing, and a spring rod. The bottom of the sealed gas tank is vertically slidably connected to the push rod, and the middle of the push rod is fixedly connected to the connector. The bottom of the connector is fixedly connected to two spring rods, and the bottom of the push rod is rotatably connected to a ball bearing.

The bottom of the storage tank is fixedly connected to the top of the baffle. A filling plug is snapped into one side of the top of the storage tank. A delivery pipe is fixedly connected to the inner wall of the storage tank. One end of the delivery pipe is placed at the bottom of the inner wall of the storage tank, and the other end of the delivery pipe passes through the storage tank and is fixedly connected to a nozzle.

[0016] A method for fermenting animal manure includes the following steps: S1: Material Preparation Animal manure is fed into a metering cylinder through a storage bin, and then evenly transported into the fermentation tank through a groove on the outside of the metering cylinder. S2: Quantitative feeding When the motor starts, it drives the lead screw to rotate. The sliding support drives the rack to move along the lead screw axis, which in turn drives the gear to rotate. The gear drives the metering cylinder to rotate through a one-way clutch, realizing metered feeding. When the metering cylinder rotates clockwise, it outputs material into the fermentation tank, ensuring the uniformity and stability of the material supply. S3: Spraying of auxiliary fermentation liquid As the metering cylinder rotates, it drives the connecting rod to move, which in turn drives the transmission block and ball bearings to compress the gas inside the sealed gas tank. The gas is then transported to the storage tank through a one-way valve, thereby driving the fermentation liquid to be sprayed onto the surface of animal feces through the delivery pipe, increasing the moisture and microbial activity of the feces and promoting the decomposition of organic matter. S4: Material crushing and processing The material is fed evenly into the crushing device by a pusher plate to crush it, ensuring that the material particles are uniform, so as to facilitate the subsequent fermentation process. S5: Anti-blocking function During material transfer, the linkage between the return spring and the striking block, through contact with the squeezing block, ensures that material accumulation or blockage is prevented, thus guaranteeing the smooth flow of material. S6: Fermentation reaction The materials undergo continuous feeding, stirring, and spraying of fermentation liquid in the fermentation tank to carry out the fermentation reaction, ensuring that the animal manure completes the fermentation process under the set temperature and humidity conditions.

[0017] (III) Beneficial Effects The beneficial effects of this invention are: 1. In this invention, through the coordinated structure of a motor, lead screw, sliding support, rack, gear, one-way clutch, and metering cylinder, the sliding support can move along the axial direction of the lead screw during the rotation of the motor-driven lead screw, driving the rack fixedly connected to it to move linearly. The rack meshes and drives the gear to rotate, and the gear, under the action of the one-way clutch, drives the metering cylinder to rotate in one direction. This allows animal manure from the storage bin to be stably fed into the metering cylinder through the trough, achieving batch-by-batch metering, avoiding material backflow or reverse compression, and improving the accuracy and stability of feeding. Through the cooperation of the adjusting rod and the capacity locking plate, the effective volume of the metering cylinder can be flexibly adjusted according to the actual fermentation needs, avoiding blockage caused by excessive feeding, improving the continuity and uniformity of material supply. The overall structure is compact, with a short transmission path, which reduces energy loss and ensures that the animal manure is in a uniform and controllable state before entering the crushing device, thus providing stable material conditions for subsequent crushing and fermentation treatment.

[0018] 2. In this invention, through the setting of a push plate, a bearing support, a connecting arm, a support plate, a fixing plate, a connecting plate, a sleeve, a return spring, a transmission rod, a striking block, and a squeezing block on one side wall of the crushing device and the storage box, the animal manure inside the bearing support can be gradually pushed into the crushing device during the movement of the sliding support, realizing stable material conveying and ensuring the continuity of crushing processing. At the same time, the sliding support drives the connecting arm to move, so that the striking block and the squeezing block interact and compress the return spring. When the striking block disengages from the squeezing block, the return spring releases its elastic force to drive the striking block to periodically strike the storage box and the outer wall of the crushing device, effectively preventing material from accumulating, adhering, or blocking at the feeding port and crushing inlet, ensuring the smooth progress of the feeding and crushing process. This striking anti-blocking mechanism relies on the movement of the sliding support to achieve automated operation, requiring no additional power source, with a simple structure and high reliability, which can significantly improve the working stability and long-term operating efficiency of the animal manure fermentation device.

[0019] 3. In this invention, an auxiliary fermentation mechanism is installed inside the storage tank. This mechanism allows the metering cylinder to rotate while discharging material, driving the connecting rod to rotate. An elliptical transmission block periodically squeezes the ball bearings, thereby driving the push rod to compress the gas inside the sealed gas tank. The compressed gas enters the storage tank through a one-way valve, squeezing the fermentation liquid within. This causes the fermentation liquid to enter the nozzle along the conveying pipe and be evenly sprayed onto the surface of the animal manure. This structure not only allows for simultaneous spraying of the fermentation liquid during manure feeding and conveying, increasing the manure's moisture content and microbial activity, but also accelerates the decomposition of organic matter, significantly improving fermentation efficiency. Compared to traditional methods relying solely on manual labor or independent spraying systems, this device utilizes the power of metered feeding to achieve automatic, linked spraying, requiring no additional energy consumption. It features a compact structure and reliable operation. Furthermore, the uniform and stable spraying process effectively prevents localized drying or excessive moisture, ensuring the stability and continuity of the material throughout the fermentation cycle.

[0022] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to Figures 1 to 11 As shown, an animal manure fermentation device and fermentation method of the present invention includes a fermentation tank 1. A gear 314, a rack 315, a one-way clutch 316, a lead screw 311, a sliding support 305, and a metering cylinder 310 are provided on one side of the fermentation tank 1. The bottom end of the gear 314 is meshed with the top end of the rack 315. A one-way clutch 316 is fixedly connected to the inner side of the rack 315. The output end of the one-way clutch 316 is fixedly connected to one end of the metering cylinder 310. A sliding support 305 is threadedly connected to the middle part of the lead screw 311. One side wall of the sliding support 305 is fixedly connected to the inner side of the rack 315. In actual implementation, the motor 7 drives the lead screw 311 to rotate. The sliding support 305, which is threaded in the middle of the lead screw 311, moves axially along the lead screw 311, driving the rack 315, which is fixedly connected to it, to move linearly. The bottom end of the rack 315 meshes with the top end of the gear 314, causing the gear 314 to rotate. Through the one-way clutch 316 fixedly connected to its inner side, the power is transmitted unidirectionally to the metering cylinder 310. This drives the metering cylinder 310 to rotate in the clockwise direction to realize material feeding. In the counterclockwise direction, the one-way clutch 316 is in an idle state to prevent material backflow. The material enters the inside of the metering cylinder 310 from the storage box 6 through the groove 318 on the outside of the metering cylinder 310 and is output quantitatively, ensuring the uniformity and stability of the material supply. This avoids affecting the crushing and fermentation effect due to uneven continuous feeding. At the same time, the compact transmission chain reduces energy loss and mechanical wear, thereby improving the overall operating efficiency and service life of the animal manure fermentation device.

[0024] Optionally, a connecting pipe 2 is fixedly connected to one side wall of the fermentation tank 1, and a crushing device 5 is connected to one end of the connecting pipe 2. A support bracket 4 is fixedly connected to the front of the crushing device 5, and a pusher plate 317 is slidably connected to the inner wall of the support bracket 4. In actual implementation, after the material is output from the metering cylinder 310, it enters the interior of the support bracket 4 and is gradually pushed towards the crushing device 5 by the pusher plate 317. This ensures that the material can be evenly fed into the crushing device 5 for crushing, effectively avoiding the accumulation and blockage of material during the conveying process, maintaining the continuous and stable working state of the crushing device 5, reducing the intensity of manual operation, improving the overall level of automation, and the pushing method of this structure can reduce material breakage and loss, making the animal manure fermentation device highly durable and stable in long-term operation.

[0025] Optionally, the top of the push plate 317 is fixedly connected to the bottom of the sliding support 305. Two limiting plates 8 are fixedly connected to one side wall of the bearing bracket 4. A motor 7 is fixedly connected to the outer side of one of the limiting plates 8. The output end of the motor 7 passes through one of the limiting plates 8 and is fixedly connected to one end of the lead screw 311. In actual implementation, when the motor 7 is running, it drives the lead screw 311 to rotate, causing the sliding support 305 to move along the direction of the lead screw 311 and drive the push plate 317 forward, thereby continuously pushing the animal manure in the bearing bracket 4 into the crushing device 5, ensuring the continuity and stability of material conveying, avoiding uneven crushing caused by intermittent feeding, and at the same time, the limiting plate 8 effectively limits the stroke of the sliding support 305 to prevent it from overstepping or deviating, improving the safety and reliability of the animal manure fermentation device during long-term operation.

[0026] Optionally, the other end of the lead screw 311 is rotatably connected to the inner side of another limiting plate 8. A slide rail 312 is fixedly connected between the two limiting plates 8. One side of the bottom end of the sliding support 305 is slidably connected to the top end of the slide rail 312. A limiting rod 3 is fixedly connected to the outer side of the slide rail 312, and one end of the limiting rod 3 is rotatably connected to the outer side of the gear 314. In actual implementation, this structure ensures that the sliding support 305 remains stable and does not deviate when moving along the lead screw 311. The guiding effect of the slide rail 312, combined with the limiting function of the limiting rod 3, can prevent poor meshing during the meshing of the rack 315 and the gear 314, improve the smoothness and stability of the transmission, and reduce wear caused by uneven force on the components, thereby extending the overall service life of the animal manure fermentation device and reducing maintenance costs.

[0027] Optionally, the top of the crushing device 5 has a storage box 6, the bottom of which is rotatably connected to the metering cylinder 310. A through groove 318 is provided on the outer side of the metering cylinder 310, and a capacity locking plate 319 is slidably connected to the inner wall of the metering cylinder 310. An adjusting rod 320 is rotatably connected to the outer side of the capacity locking plate 319, and the adjusting rod 320 is threadedly connected to the outer side of the metering cylinder 310. In actual implementation, the user can rotate the adjusting rod 320 to move the capacity locking plate 319, thereby adjusting the effective volume of the metering cylinder 310. This allows for precise feeding according to material characteristics or subsequent processing requirements, avoiding feeding congestion or overfeeding caused by improper metering, improving the adaptability and flexibility of the animal manure fermentation device, and maintaining the uniformity of material supply, providing a stable material foundation for subsequent crushing and fermentation processes.

[0028] Optionally, a pressing block 301 is fixedly connected to one side wall of the crushing device 5 and one side wall of the storage bin 6. A connecting arm 304 is fixedly connected to the other side wall of the sliding support 305. A support plate 309 is fixedly connected to the top of the connecting arm 304, and a fixing plate 308 is fixedly connected to the support plate 309. In actual implementation, when the sliding support 305 moves, it can drive the connecting arm 304, the support plate 309, and the fixing plate 308 to move as a whole, so that the structure on the fixing plate 308 comes into contact with and presses the pressing block 301, thereby realizing the mechanical triggering or position adjustment of the relevant components. This ensures that the various mechanisms can operate in a coordinated manner during material transmission and crushing, reduces operational failures caused by changes in material characteristics or component wear, and improves the overall stability and durability of the animal manure fermentation device.

[0029] Optionally, a connecting plate 302 is fixedly connected to one end of the connecting arm 304. A sleeve 306 is fixedly connected to the inner side of both the fixed plate 308 and the inner side of the connecting plate 302. A return spring 322 is fixedly connected to the inner wall of the sleeve 306. In actual implementation, when the sliding support 305 moves, causing the connecting arm 304 and the connecting plate 302 to move, the return spring 322 can store elastic potential energy after being compressed and release energy when the compression is released, driving the relevant components to return to their initial position. This ensures the repeatability and stability of the mechanism's cyclical operation, while avoiding positional deviations caused by the inertia of mechanical components, improving the continuity and accuracy of the animal manure fermentation device's operation, and reducing the frequency of manual intervention.

[0030] Optionally, a transmission rod 321 is vertically slidably connected to the inner wall of the sleeve 306. One end of the return spring 322 is fixedly connected to the inner side of the transmission rod 321, and a striking block 307 is fixedly connected to the outer side of the transmission rod 321. The striking block 307 is matched with the position of the extrusion block 301. In actual implementation, when the connecting plate 302 and the fixed plate 308 move and drive the striking block 307 to contact the extrusion block 301, the return spring 322 can be compressed and rebounded quickly upon release, so that the striking block 307 strikes the outer side of the storage box 6 and the outer side of the crushing device 5. This effectively prevents the material from adhering, accumulating, or clogging at the inlet of the storage box 6 or the crushing device 5, maintains the smoothness and stability of material flow, and improves the anti-clogging performance of the animal manure fermentation device under long-term continuous operation.

[0031] Optionally, the bottom end of the pusher plate 317 is attached to the inner wall of the support bracket 4, and the bottom end of the connecting plate 302 is slidably connected to the guide rail 303, which is fixedly connected to the outer wall of the crushing device 5. In actual implementation, the pusher plate 317 is smoothly advanced along the guide rail 303 under the drive of the sliding support 305, avoiding the pusher plate 317 from tilting or getting stuck during operation. This ensures that the material can be evenly conveyed along the support bracket 4 to the feed inlet of the crushing device 5, preventing local accumulation or empty material, improving the uniformity and efficiency of material conveying, and reducing component wear caused by uneven friction of the pusher plate 317, thus extending the service life of the animal manure fermentation device.

[0032] Optionally, a connecting rail 313 is fixedly connected to the top of the two limiting plates 8, and the bottom end of the rack 315 is slidably connected to the outside of the connecting rail 313. The inner side of the rack 315 is fixedly connected to the outer wall of the sliding support 305. In actual implementation, the fixed connection between the inner side of the rack 315 and the outer wall of the sliding support 305 allows the rack 315 to move stably along the connecting rail 313 under the drive of the sliding support 305, maintaining the meshing accuracy with the gear 314. This avoids meshing failure or transmission obstruction due to deviation of the rack 315's movement trajectory, improves the reliability and durability of the transmission system, and reduces noise and energy consumption caused by poor meshing between the gear 314 and the rack 315, thereby improving the overall working performance of the animal manure fermentation device.

[0033] Optionally, the storage tank 6 is equipped with an auxiliary fermentation mechanism 9. The auxiliary fermentation mechanism 9 includes a sealed gas tank 910, a one-way valve 909, a push rod 911, a connector 912, a ball bearing 914, and a spring rod 913. The bottom end of the sealed gas tank 910 is vertically slidably connected to the push rod 911. The middle part of the push rod 911 is fixedly connected to the connector 912. The bottom end of the connector 912 is fixedly connected to two spring rods 913. The bottom end of the push rod 911 is rotatably connected to the ball bearing 914. The free ends of the two spring rods 913 are attached to the outer wall of the ball bearing 914. The middle part of the sealed gas tank 910 is connected to the one-way valve 909. The inner wall of the storage tank 6 is rotatably connected to a connecting rod 907. One end of the connecting rod 907 is rotatably connected to a transmission block 908. The bottom end of the connecting rod 907 is attached to the top of the metering cylinder 310. In actual implementation, the rotation of the metering cylinder 310 drives the connecting rod 907 to move, causing the transmission block 908 to squeeze the ball bearing 914 and push the push rod 911, thereby compressing the gas inside the sealed gas tank 910. The gas is transported under the action of the one-way valve 909, providing power for the spraying of fermentation liquid, realizing the linkage between material feeding and liquid spraying, and improving the level of automation.

[0034] A sealed gas cylinder 910 is fixedly connected to the inside of a baffle 906. A fixing pipe 901 is fixedly connected to the top of the sealed gas cylinder 910, and a storage tank 903 is fixedly connected to the bottom of the fixing pipe 901. The bottom of the storage tank 903 is fixedly connected to the top of the baffle 906. A filling plug 902 is snapped onto one side of the top of the storage tank 903. A conveying pipe 904 is fixedly connected to the inner wall of the storage tank 903. One end of the conveying pipe 904 is placed at the bottom of the inner wall of the storage tank 903, and the other end of the conveying pipe 904 passes through the storage tank 903 and is fixedly connected to a nozzle 905. In actual implementation, the sealed gas cylinder 910 provides air pressure to the storage tank 903, causing the fermentation liquid inside the storage tank 903 to be evenly compressed. After entering the nozzle 905 through the conveying pipe 904, it is sprayed onto the surface of the feces, ensuring that the humidity of the feces is suitable and the activity of the microorganisms is stable during the fermentation process, thereby accelerating the decomposition of organic matter, improving the overall fermentation efficiency, and improving the continuous operation capability of the device.

[0035] Optionally, a method for fermenting animal manure includes the following steps: S1: Material Preparation Animal manure is fed into metering cylinder 310 through storage bin 6, and then evenly transported into fermentation tank 1 through the groove 318 opened on the outside of metering cylinder 310. S2: Quantitative feeding When the motor 7 starts, it drives the lead screw 311 to rotate. Through the sliding support 305, it drives the rack 315 to move along the axial direction of the lead screw 311, thereby driving the gear 314 to rotate. The gear 314 drives the metering cylinder 310 to rotate through the one-way clutch 316, realizing metered feeding. When the metering cylinder 310 rotates clockwise, it outputs materials into the fermentation tank 1, ensuring the uniformity and stability of the material supply. S3: Spraying of auxiliary fermentation liquid While the metering cylinder 310 rotates, it pushes the connecting rod 907 to move, which in turn drives the transmission block 908 and the ball bearing 914 to compress the gas inside the sealed gas tank 910. The gas is then transported to the storage tank 903 through the one-way valve 909, thereby driving the fermentation liquid to be sprayed onto the surface of animal feces through the delivery pipe 904, increasing the humidity and microbial activity of the feces and promoting the decomposition of organic matter. S4: Material crushing and processing The material is fed evenly into the crushing device 5 by the pusher plate 317 for crushing, ensuring that the material particles are uniform, so as to facilitate the subsequent fermentation process. S5: Anti-blocking function During material transfer, the linkage between the return spring 322 and the striking block 307, through contact with the squeezing block 301, ensures that material accumulation or blockage is prevented and that the material flow is smooth. S6: Fermentation reaction The materials undergo continuous feeding, stirring, and spraying of fermentation liquid in fermentation tank 1 to carry out the fermentation reaction, ensuring that the animal manure completes the fermentation process under the set temperature and humidity conditions.

[0036] Working principle: After the motor 7 starts, its output end drives the lead screw 311 to rotate. The middle part of the lead screw 311 is threadedly connected to the sliding support 305. Therefore, during the rotation of the lead screw 311, the sliding support 305 moves axially along the lead screw 311. During the movement of the sliding support 305, one side wall is fixedly connected to the inner side of the rack 315. The bottom end of the rack 315 meshes with the top end of the gear 314. Therefore, the movement of the rack 315 will drive the gear 314 to rotate. A one-way clutch 316 is fixedly connected to the inner side of the gear 314. The output end of the one-way clutch 316 is fixedly connected to one end of the metering cylinder 310. When the gear 314 rotates clockwise, it can drive the metering cylinder 310 to rotate synchronously through the one-way clutch 316. When 314 rotates counterclockwise, the one-way clutch 316 is in an idle state and will not drive the metering cylinder 310, thus effectively preventing material backflow. The metering cylinder 310 is rotatably connected to the bottom of the storage bin 6. During the rotation of the metering cylinder 310, animal manure inside the storage bin 6 can enter its interior through the through-slot 318 on the outside of the metering cylinder 310, achieving metered feeding. The user can rotate the adjusting rod 320, which is threaded to the outside of the metering cylinder 310, to drive the capacity locking plate 319 to slide on the inner wall of the metering cylinder 310, thereby changing the effective volume of the metering cylinder 310 and preventing blockage due to excessive feeding. While the metering cylinder 310 is feeding, its outer wall is in frictional contact with the connecting rod 907, which is rotatably connected to the inner wall of the storage bin 6. Both surfaces are relatively rough, enabling reliable frictional transmission, which drives the connecting rod 907 to rotate. When the connecting rod 907 rotates, the transmission block 908, which is fixedly connected to one end, also rotates. The transmission block 908 has an elliptical structure, and during rotation, it periodically squeezes the ball bearing 914, causing the ball bearing 914 to drive the push rod 911 to move, thereby compressing the gas inside the sealed gas tank 910. Under the action of the one-way valve 909, the gas enters the fixed pipe 901 and is transported to the storage tank 903. After the gas in the storage tank 903 is compressed, it will exert a squeezing effect on the fermentation liquid inside, causing the fermentation liquid to enter the nozzle 905 along the conveying pipe 904, and thus be sprayed onto the surface of the animal manure in the storage bin 6, effectively increasing its moisture content and microbial activity. The sliding support 305 accelerates the fermentation process of feces. Simultaneously, the bottom end of the sliding support 305 is fixedly connected to the push plate 317, which is slidably connected to the inner wall of the bearing support 4. Therefore, when the sliding support 305 moves, the push plate 317 can gradually push the animal feces inside the bearing support 4 into the crushing device 5, ensuring the material continuously and evenly enters the crushing device 5 for crushing. During the movement of the sliding support 305, it also drives the support plate 309, the fixed plate 308, and the connecting plate 302 to move synchronously through the fixedly connected connecting arm 304. Both the fixed plate 308 and the connecting plate 302 have sleeves 306 on their inner sides, and a return spring 322 is fixedly connected to the inner wall of the sleeve 306. One end of the return spring 322 is fixed to the transmission rod 321.A striking block 307 is fixedly connected to the outer side of the transmission rod 321. When the sliding support 305 moves, the striking block 307 contacts and is compressed against the extrusion block 301 on the outer wall of the crushing device 5 and the storage box 6, causing the return spring 322 to store energy. When the striking block 307 disengages from the extrusion block 301, the return spring 322 releases its elastic force, causing the striking block 307 to strike the outer wall of the storage box 6 and the crushing device 5, thereby preventing material from accumulating and clogging at the discharge port or crushing inlet. After receiving the animal manure pushed in by the pusher plate 317, the crushing device 5 crushes it into relatively uniform particles, providing suitable raw materials for the subsequent fermentation process. Thus, the motor 7 drives the lead screw 311, which in turn drives the sliding support 305. The sliding support 305 drives the rack 315, which in turn drives the gear 314. The gear 314, through a one-way clutch 316, drives the metering cylinder 310 to discharge the material. Simultaneously, the rotation of the metering cylinder 310 drives the auxiliary fermentation mechanism 9, causing the compressed gas in the sealed gas tank 910 to propel the fermentation liquid onto the surface of the manure, enhancing the fermentation effect. Then, the pusher plate 317 feeds the material into the crushing device 5 for crushing, with a striking component providing anti-clogging functionality, ensuring the device maintains stability and high efficiency even during long-term operation.
