Description

Technical Field

[0001] The invention relates to the technical field of aquaculture waste fermentation, in particular to an organic waste fermentation device for animal husbandry. Background Art

[0002] Fermentation of organic waste from animal husbandry is a key link in realizing the resource utilization of animal husbandry waste. This process uses the decomposition of microorganisms to convert organic waste such as livestock and poultry manure and feed into nutrient-rich organic fertilizer or feed raw materials. In the fermentation facility, a suitable growth environment is created for microorganisms by reasonably regulating conditions such as temperature, humidity, and ventilation. For example, medium-temperature fermentation generally maintains the temperature at 30℃-40℃, and high-temperature fermentation at 50℃-60℃ to accelerate the decomposition and transformation of organic matter. Appropriate humidity can maintain the activity of microorganisms, usually controlled at 50%-60%. Good ventilation can ensure the smooth progress of aerobic fermentation and avoid the production of harmful gases. After a period of fermentation, pathogens and parasite eggs in organic waste are killed, and macromolecular organic matter is decomposed into small molecular humic acid, amino acids, etc., which not only solves the problem of environmental pollution caused by animal husbandry waste, but also provides high-quality fertilizers for agricultural production, promotes the ecological cycle of animal husbandry and agricultural planting, and promotes the development of green agriculture.

[0003] During the fermentation process of livestock organic waste, if the waste gas in the fermentation tank is not discharged, it will cause many serious hazards. First, fermentation will produce a large amount of carbon dioxide. If it accumulates in the tank, it will reduce the oxygen content in the tank, leaving the microorganisms in an oxygen-deficient environment, greatly inhibiting their activity, causing a sharp drop in fermentation efficiency, extending the fermentation cycle, and even causing fermentation to stagnate, making it impossible to effectively transform organic waste. Secondly, the accumulation of waste gas in the tank will also increase the pressure in the tank, threatening the structure of the fermentation tank, and may cause safety accidents such as tank rupture and leakage, causing casualties and environmental pollution.

[0021] Working principle: When in use, the operator pours the waste generated by animal husbandry into the inner cavity of the fermentation tank 1, then aligns the locking rod 7 on the lower surface of the top cover 8 with the locking ring 4, and squeezes downward until the sealing ring 3 is in tight contact with the lower surface of the top cover 8; then turns on the switch of the storage battery 52, so that the heating plate 53 heats the water flow in the inner cavity of the water tank 55, and then the operator connects the water pump 57 to the power supply and turns on the switch, so that the water pump 57 starts to work, and the water flow in the inner cavity of the water tank 55 is discharged into the inner cavity of the first spiral tube 58, and cooperates with the second spiral tube 59 to make the water flow generate a spiral flow in the inner cavity of the fermentation tank 1 , and finally the temperature in the inner cavity of the fermentation tank 1 is increased, so that the waste can complete the fermentation at an appropriate temperature.

When the rotating tube 610 drives the second gear 621 to rotate clockwise, the first gear 64 drives the connecting frame 65 to rotate counterclockwise, so that the stirring plate 66 is located in the middle and upper part of the inner cavity of the fermenter 1, and the organic waste in the middle and upper part can be stirred. When the rotating tube 610 drives the second gear 621 to rotate counterclockwise, the first gear 64 drives the connecting frame 65 to rotate clockwise, so that the stirring plate 66 is located in the middle and lower part of the inner cavity of the fermenter 1, and the waste at the bottom of the inner cavity of the fermenter 1 is stirred. Therefore, by adjusting the flow direction of the water pump 57, the effect of shaking up and down is achieved. When a large amount of waste gas is generated during the fermentation process, the air pressure in the inner cavity of the sealing tube 946 increases with the increase of the air pressure in the inner cavity of the fermentation tank 1, thereby causing the piston 947 to move and the sealing frame 944 no longer blocks the air inlet 910. Then, the air flow enters the inner cavity of the circular tube 93 through the air inlet 910 and flushes the second spiral sheet 917, thereby causing the straight tube 915 to drive the second rotating column 97 to rotate, so that the waste gas in the inner cavity of the fermentation tank 1 can be discharged. After the discharge, the air pressure returns to balance, and the sealing frame 944 blocks the air inlet 910 again, making the inner cavity of the fermentation tank 1 a closed environment.
