[0033] In one embodiment of the present application, the bottom of the compost fermentation tank 1 is connected with a shunt pipeline 54, the shunt pipeline 54 is connected with a liquid manure temporary storage tank 58, an electromagnetic valve is arranged on the shunt pipeline 54, so that the liquid manure is shunted when the liquid manure is about to overflow the compost fermentation tank 1, a liquid level sensor is arranged in the compost fermentation tank 1 and is signal connected with the electromagnetic valve, the other side of the bottom of the compost fermentation tank 1 is provided with a sewage pipeline 53, an electromagnetic valve is also arranged on the sewage pipeline 53, the sewage pipeline 53 is connected with a liquid-solid separation device 59 of liquid manure through a sewage guide pipe 62, and the liquid-solid separation device 59 of liquid manure is provided with a liquid organic fertilizer discharge port 60 at one side of the bottom and is provided with a solid organic fertilizer discharge port 61 at one end.

[0034] Working principle: when the liquid manure compost fermentation organic fertilizer processing device is used to process liquid manure into organic fertilizer, the relevant personnel first pour the liquid manure into the compost fermentation tank 1 to the working liquid level, and then start the aeration assembly 2 to perform aeration work. First, the relevant personnel first start the lifting motor 9, the push rod pushes the extension plate 10 and the annular lifting plate 7 to rise, and the clamping top cover 40 of all the anti-blocking aeration devices 6 is synchronously lifted through the hanger rod 11. The clamping top cover 40 drags the dragging part 46 in the compressed state upward through the stretching pull rod 41, and then pushes away the various expansion supporting plates 49 to the working angle through the expansion push rod 47, so that the aeration module 50 is completely exposed, and then the aeration fan 5 is started, so that air is transported to each aeration module 50 through the aeration guide pipe 12, the annular pipeline 8 and the aeration branch pipe 48, and is uniformly released as fine bubbles from the aeration head 51 to perform aeration work, so that the liquid manure is subjected to aerobic fermentation and composting. Then, the relevant personnel open the compost stirring assembly 3 to stir the fecal pollution, the relevant personnel start the stirring motor 16 through the controller, make the driving shaft 15 drive each layer of stirring rod 23 rotate around the shaft, start the basic stirring, with the rotation of the stirring rod 23, the guide roller 25 at the end thereof rolls along the adjusting guide rail 14 of the inner wall of the compost fermentation tank 1 at this time. When the guide roller 25 enters the convex part 18 of the adjusting guide rail 14, a radial thrust is generated, which pushes the driving gear plate 31 in the buffer cavity 33 to move inward against the elastic force of the buffer spring 34, at the same time, the driving gear plate 31 drives the adjusting gear 27 meshing therewith to rotate, thereby driving the adjusting shaft 28 and the adjusting plate 29 fixed thereon to swing. The adjusting plate 29 controls the adjusting connecting plate 38 through the rotating supporting plate 30 at both ends and pulls all the stirring paddles 36 to deflect by a certain angle synchronously around the first connecting end 56. Conversely, when the guide roller 25 enters the recessed part 19, the driving gear plate 31 moves reversely under the resetting action of the buffer spring 34, driving the stirring paddles 36 to deflect reversely, realizing the periodic dynamic change of the attack angle of the stirring paddles 36 with the periodic revolution of the stirring, effectively promoting the contact effect of the fecal pollution and the aeration air, making the organic matter in the fecal pollution fully compost, avoiding local nutrient imbalance, improving the uniformity of the fertilizer, and bringing protection for the processing of organic fertilizer; When the fecal pollution is poured into excess or the fermentation gas causes the liquid level in the pool to abnormally rise, the anti-overflow assembly 4 will automatically start (real-time monitoring by the built-in liquid level sensor and connection with the electromagnetic valve of the shunt pipeline 54 through the controller), at this time, the annular floating plate 20 floats along the limiting rod 22 under the action of buoyancy, unfolds the waterproof fabric 21 connected at the bottom thereof, forms a temporary expanded volume, effectively buffers the liquid level rise, at the same time, the liquid level sensor installed in the pool sends a signal to automatically open the electromagnetic valve of the shunt pipeline 54, and part of the fecal pollution is shunted to the fertilizer liquid temporary storage tank 58 for temporary storage and fermentation. The double mechanisms work together to effectively prevent overflow accidents. When the processing is completed or needs to be repaired, first stop stirring and aeration, then reverse operation of the lifting motor 9 to make the unfolded supporting plate 49 of the anti-clogging aeration device 6 fold and be resealed by the clamping top cover 40, effectively preventing the fecal pollution from clogging the aeration head 51 during shutdown, and preparing for the next start; The liquid fecal pollution after fermentation can be discharged into the fecal pollution solid-liquid separation device 59 by opening the electromagnetic valve of the sewage pipeline 53, and the solid organic impurities mixed in the liquid fecal pollution are separated from the liquid fecal pollution by opening the fecal pollution solid-liquid separation device 59, so that the liquid organic fertilizer and the solid organic fertilizer are discharged from the liquid organic fertilizer discharge port 60 and the solid organic fertilizer discharge port 61 respectively, and the corresponding containers are used to collect them, thereby realizing the processing of organic fertilizer from fecal pollution.

[0035] To sum up, the liquid manure composting fermentation organic fertilizer processing device has the following advantages: the linkage structure composed of the adjusting guide rail and the adjustable vertical paddle stirring assembly enables the stirring paddle to periodically and automatically deflect an angle while revolving, which breaks the traditional steady flow field, continuously disturbs the tank bottom and constantly changes the fluid direction, thereby preventing the solid particles from settling in a dead angle, dynamically optimizing the contact path and time of the manure and the aeration bubbles, significantly improving the oxygen transfer efficiency and mixing uniformity, fully composting the organic matter in the manure, avoiding local nutrient imbalance, improving the uniformity of the fertilizer and guaranteeing the processing of the organic fertilizer; the anti-blocking aeration device can be expanded and contracted; during the non-aeration period, the lifting motor drives the annular lifting plate to enable the expanded supporting plate and the aeration module thereon to be folded and clamped and sealed by the top cover, thereby effectively preventing the pollution; the anti-blocking aeration device is expanded when aeration is needed, which fundamentally avoids the blocking of the aeration head, reduces the maintenance frequency, ensures the uniformity of aeration and the continuity of the whole fermentation process; the anti-overflow structure is composed of the annular floating plate, the waterproof fabric and the shunt pipeline; when the liquid level rises, the annular floating plate floats and expands the waterproof fabric, temporarily expands the volume to buffer the liquid level; the liquid level sensor cooperated with the annular floating plate controls the electromagnetic valve of the shunt pipeline to be opened, thereby automatically shunting the excess manure to other containers, effectively avoiding the secondary pollution caused by overflow.

[0036] For the liquid manure to be overflowed, the liquid manure temporary storage tank communicated with the composting fermentation tank is arranged to temporarily store the manure to be overflowed, thereby avoiding the waste of nutrients caused by the loss of the liquid manure; the solid-liquid manure separation device arranged on the other side of the composting fermentation tank separates the solid organic matter mixed in the liquid manure by the screw extrusion mode, thereby realizing the separate output of the liquid organic fertilizer and the solid organic fertilizer and facilitating the classified collection and utilization of the organic fertilizer.
