TECHNICAL FIELD
[0001] The utility model belongs to solid waste treatment field relates to a kind of aerobic composting equipment, especially to a kind of simple type agricultural solid waste aerobic composting equipment. BACKGROUND
[0002] Composting is to use various organic wastes (such as crop straw, weeds, leaves, peat, organic household garbage, kitchen garbage, sludge, human and animal excrements, vinasse, fungus chaff and other wastes, etc.) as main raw materials, and to use the fermentation of microorganisms widely distributed in nature, such as bacteria, actinomycetes and fungi, to promote the transformation of degradable organic matter in solid waste into stable humus in a controlled manner. As a kind of artificial humus, compost is rich in nutrients, which is beneficial to promote the formation of soil aggregate structure, and can increase the ability of soil to retain water, heat, air and fertilizer, with long and stable fertilizer effect. When mixed with chemical fertilizer, it can make up for the single nutrient contained in chemical fertilizer and the defects of soil hardening, water retention and fertilizer retention caused by long-term use of chemical fertilizer.
[0003] Currently, when aerobic composting is carried out, the following two modes are often used:
[0004] Mode one: traditional composting. Organic waste is stacked into a pile or other shapes, and is turned over by a turning machine (or a forklift or other turning equipment) to achieve the purpose of oxygen supplementation; or oxygen is supplemented by pre-laid pipes to promote the fermentation process of aerobic composting. This mode is simple to operate and has simple technology, and is suitable for large-scale fermentation of organic waste, but it occupies a large area and is easy to form clumps due to aggregation, which leads to slow decomposition of organic matter, prolongs the fermentation period, and reduces the fermentation efficiency, and causes secondary pollution. This mode is commonly used for independent operation by farmers or for connected operation by cooperatives.
[0005] Mode two: fermentation tank composting. Organic waste is placed in a closed fermentation tank, and the temperature, humidity, ventilation volume and stirring frequency in the tank are precisely controlled to create ideal environmental conditions for microorganisms to decompose organic matter, so as to promote the rapid transformation of organic waste into stable compost products. This mode can efficiently utilize space, has a short fermentation period, realizes the rapid stabilization of organic waste and the transformation of organic waste into high-quality compost, and reduces the risk of pollution; but it has high equipment cost, high technical requirements and high energy consumption, and the treatment capacity of organic waste is small, so this mode is suitable for small-scale use in cities, colleges or research institutions, and is not conducive to agricultural production.
