Description

Technical Field

[0001] The invention belongs to the technical field of fermentation, and in particular relates to a mixed fermentation device and a fermentation method for livestock and poultry manure and plant straw. Background Art

[0002] Agricultural wastes such as livestock and poultry manure and straw are difficult to control agricultural pollution. The mixed fermentation of livestock and poultry manure and straw has the following advantages: 1. Reduce environmental pollution: The mixed fermentation of livestock and poultry manure and plant straw can effectively reduce environmental pollution. After fermentation, manure and straw can be converted into organic fertilizer or biomass fuel, avoiding direct discharge pollution to soil, water and air; 2. Resource utilization: Through mixed fermentation, waste can be converted into valuable resources. The organic fertilizer produced during the fermentation process can improve soil structure, increase soil fertility and promote crop growth; while biomass fuels such as biogas can be used for energy supply in rural areas and reduce dependence on fossil fuels; 3. Improve soil quality: The organic fertilizer produced during the fermentation process contains rich organic matter and microbial flora, which can improve the physical properties of the soil, enhance the soil's air permeability, water retention and fertilizer retention capabilities, prevent soil compaction and acidification, and thus improve the quality of arable land.

[0003] In the existing mixed fermentation of livestock and poultry manure and plant straw, in order to achieve large-scale fermentation, it is necessary to prepare more fermentation pools or fermentation barrels for fermentation operations. However, when fermenting, traditional fermentation barrels lack the exchange of raw materials between barrels. Due to the different environments in different barrels, the degree of fermentation is also different. For example, some barrels have fewer fermentation bacteria, resulting in slow fermentation. Moreover, during fermentation, the top is usually open to contact the air for aerobic fermentation, and air cannot enter the interior to fully contact the raw materials, affecting the efficiency of aerobic fermentation. For this reason, we propose a mixed fermentation device and fermentation method for livestock and poultry manure and plant straw. Summary of the invention

[0060] When the large disc 705 rotates, it drives the guide rod 801 to rise and fall through the guide groove 707, and the guide rod 801 drives the movable rod 803 to rise and fall through the movable ring 802, and the movable rod 803 drives the piston 804 to rise and fall in the air cylinder 805, which squeezes the air into the fixed pipe 3 through the one-way valve 807. After the piston 804 comes to the top of the air inlet hole 806, the air will be replenished into the air cylinder 805 through the air inlet hole 806. At the same time, the movable rod 803 also drives the lifting rod 808 to rise and fall, and the lifting rod 808 drives the lifting plate 810 to rise and fall through the fixed seat 809. The lifting and lowering of the lifting plate 810 will drive the swing rod 906 to move up and down, and the swing rod 906 will drive the movable arm 907 to move around the fixed rod 908. When the swing rod 906 moves, it also drives the push-pull plate 905 to move up and down.
