Liquid manure is rich in nutrients such as nitrogen, phosphorus and potassium, and can be converted into efficient organic fertilizer through aerobic fermentation, realizing resource utilization. The existing fermentation device focuses on the treatment of standard discharge, and lacks design for optimizing fertilizer quality, resulting in low fertility of fermentation products and difficulty in direct use as fertilizer.

[0046] In one embodiment of the present invention, a diversion pipe 54 is connected to one side of the bottom of the fermentation tank 1. The diversion pipe 54 is connected to the fertilizer liquid storage tank 58. A solenoid valve is installed on the diversion pipe 54 to divert the manure when it is about to overflow from the fermentation tank 1. A liquid level sensor is installed inside the fermentation tank 1 and is connected to the solenoid valve signal. A sewage discharge pipe 53 is installed on the other side of the bottom of the fermentation tank 1. A solenoid valve is also installed on the sewage discharge pipe 53. The sewage discharge pipe 53 is connected to the manure solid-liquid separation device 59 through a sewage discharge conduit 62. A liquid organic fertilizer discharge port 60 is provided at the bottom of one side of the manure solid-liquid separation device 59, and a solid organic fertilizer discharge port 61 is provided at one end of the manure solid-liquid separation device 59.

[0047] Working principle: When using the liquid manure composting and fermentation organic fertilizer processing device of the present invention to process liquid manure into organic fertilizer, the relevant personnel first pour the liquid manure into the composting and fermentation tank 1 to the working liquid level, and then start the aeration component 2 to carry out aeration operation.

[0048] First, the relevant personnel start the lifting motor 9, whose push rod pushes the extension plate 10 and the annular lifting plate 7 to rise, and simultaneously lifts the clamping top cover 40 of all anti-clogging aeration devices 6 through the hoisting rod 11. The clamping top cover 40 is pulled upward by the extension rod 41 to the compressed drag part 46, and then the unfolding push rod 47 pushes each unfolding support plate 49 to the working angle, so that the aeration module 50 is fully exposed. Then, the aeration blower 5 is started, so that air is delivered to each aeration module 50 through the aeration duct 12, the annular pipe 8 and the aeration branch pipe 48, and is evenly released from the aeration head 51 as fine bubbles for aeration, so that the manure can undergo aerobic fermentation and decomposition.

[0049] Next, the relevant personnel start the composting mixing assembly 3 to mix the manure. They activate the mixing motor 16 via the controller, causing the drive shaft 15 to rotate the mixing rods 23 of each layer around the shaft, initiating basic mixing. As the mixing rods 23 rotate, their guide rollers 25 roll along the adjusting guide rail 14 on the inner wall of the composting fermentation tank 1. When the guide rollers 25 enter the protrusion 18 of the adjusting guide rail 14, a radial thrust is generated. This thrust, via the telescopic guide rod 24, pushes the drive toothed plate 31 inward within the buffer chamber 33, overcoming the elasticity of the buffer spring 34. Simultaneously, the drive toothed plate 31 drives the adjusting gear 27, which meshes with it, to rotate, thereby causing the adjusting shaft 28 and the adjusting plate 29 fixed thereon to swing. The adjusting plate 29, through the rotating support plates 30 at both ends, controls the adjusting connecting plate 38 and pulls all the mixing blades 36 to synchronously deflect a certain angle around their first connecting end 56. Conversely, when the guide roller 25 enters the recess 19, under the reset action of the buffer spring 34, the toothed plate 31 is driven to move in the opposite direction, which drives the stirring blade 36 to deflect in the opposite direction. This realizes the periodic dynamic change of the angle of attack of the stirring blade 36 with the revolution of the stirring, which effectively promotes the contact effect between the manure and the aerated air, so that the organic matter in the manure is fully decomposed, avoids local nutrient imbalance, improves the uniformity of fertilizer, and provides a guarantee for the processing of organic fertilizer.

[0050] When excessive amounts of manure are poured in or fermentation gas causes an abnormal rise in the liquid level in the tank, the anti-overflow component 4 will automatically activate (monitored in real time by a built-in liquid level sensor and connected to a solenoid valve at the diversion pipe 54 via a controller). At this time, the annular float 20 floats up along the limit rod 22 under buoyancy, unfolding the waterproof fabric 21 connected to its bottom to form a temporary expanded volume, effectively buffering the rise in the liquid level. Simultaneously, the liquid level sensor installed in the tank sends a signal to automatically open the solenoid valve on the diversion pipe 54, diverting some of the manure to the fertilizer storage tank 58 for temporary storage and fermentation. This dual mechanism works together to effectively prevent leakage accidents. When processing is complete or maintenance is required, first stop stirring and aeration, then reverse the operation of the lifting motor 9 to retract the unfolding support plate 49 of the anti-clogging aeration device 6 and lock it in place with the top cover 40 for resealing, effectively preventing sludge from clogging the aeration head 51 during shutdown and preparing for the next startup.

[0051] After fermentation, the liquid manure can be fed into the manure solid-liquid separation device 59 by opening the solenoid valve on the sewage pipe 53. By turning on the manure solid-liquid separation device 59, the solid organic impurities mixed in with the liquid manure are separated from the liquid manure, so that the liquid organic fertilizer and solid organic fertilizer are discharged from the liquid organic fertilizer discharge port 60 and the solid organic fertilizer discharge port 61, respectively. Relevant personnel use corresponding containers to collect them separately, thereby realizing the organic fertilizer processing of manure.

[0052] In summary, the liquid manure composting and fermentation organic fertilizer processing device of the present invention utilizes a linkage structure consisting of an adjustable guide rail and an adjustable vertical paddle stirring assembly. This allows the stirring paddle blades to periodically and automatically deflect their angles while revolving. This design breaks the traditional steady-state flow field, continuously disturbing the bottom of the tank and constantly changing the fluid direction, thereby preventing solid particle settling without dead angles. It also dynamically optimizes the contact path and time between manure and aeration bubbles, significantly improving oxygen transfer efficiency and mixing uniformity. This ensures the full composting of organic matter in the manure, avoids local nutrient imbalances, improves fertilizer uniformity, and provides a guarantee for organic fertilizer processing. The device also features an expandable and retractable anti-clogging aeration device. During non-aeration periods, a lifting motor drives a ring-shaped lifting plate, allowing the expanded tray and its aeration module to retract and be locked in place by the top cover, effectively isolating contaminants. When aeration is needed, it is expanded again. This mechanism fundamentally avoids clogging of the aeration heads, reduces maintenance frequency, and ensures aeration uniformity and the continuity of the entire fermentation process. The overflow prevention structure consists of an annular float, waterproof fabric, and diversion pipes. When the liquid level rises, the annular float rises and unfolds the waterproof fabric, temporarily expanding the volume to buffer the level. The liquid level sensor, in conjunction with the float, controls the solenoid valve of the diversion pipe to open, automatically diverting excess sewage to other containers, effectively preventing secondary pollution caused by spills.

[0053] For liquid manure that is about to overflow, it is temporarily stored and fermented in a fertilizer liquid storage tank connected to the composting and fermentation tank to avoid fertilizer loss and nutrient waste. At the same time, a solid-liquid manure separation device set on the other side of the composting and fermentation tank uses a screw extrusion method to separate the solid organic matter mixed in the liquid manure, so as to achieve the separate production of liquid organic fertilizer and solid organic fertilizer, so as to facilitate the classification, collection and utilization of organic fertilizer.
