Method for manufacturing bio-dynamic agricultural compost and compost fermentation vat

Abstract

The invention relates to the field of utilization of agricultural resources, in particular to a method for manufacturing a bio-dynamic agricultural compost and a compost fermentation vat. The method comprises the following steps: putting composting raw materials into a vat body; supplementing oxygen for the bottoms of the composting raw materials through an oxygenating device; after the beginning of fermentation, pushing the composting raw materials to move forwards along the vat body step by step by use of a turning and pushing machine; along with step-by-step propulsion of the composting raw materials, sequentially adding composting regulation elements, and supplementing oxygen for the composting raw materials; in every step of movement, turning the composting raw materials mixed with the composting regulation elements through the turning and pushing machine. The method has the following beneficial effects; the regulation elements can be added according to the fermentation progress, oxygen can be supplemented, and together with turning, the fermentation time is shortened, fertilizer composting is quickened, the method is suitable for industrial production of the bio-dynamic agricultural compost, and the problems in the prior art are economically and effectively solved.

Description

technical field [0001] The invention relates to the field of utilization of agricultural resources, in particular to a method for producing biodynamic agricultural compost and a compost fermentation tank. Background technique [0002] Use natural microorganisms or inoculated microorganisms to quickly deodorize and decompose domestic waste. It has the characteristics of fast fermentation speed, short cycle, and easy mechanization operation. Pathogenic bacteria, insect eggs, etc. are killed, and the transformed organic fertilizer belongs to "hygienic fertilizer". Therefore, this method has been adopted by many enterprises. [0003] At present, the main composting method is to set up an air channel at the bottom of the raw material pile after cleaning the fermentation point to ensure sufficient oxygen supply during the fermentation process; to screen the raw materials and make the mixed raw material pile into a pile with a width of no more than 2 meters and a height of no more ...

Problems solved by technology

[0003] At present, the main composting method is to set up an air channel at the bottom of the raw material pile after cleaning the fermentation point to ensure sufficient oxygen supply during the fermentation process; to screen the raw materials and make the mixed raw material pile into a pile with a width of no more than 2 meters and a height of no more than 1.5 meters. or stack the fertilizer raw materials in layers to form a fertilizer pile with a width of no more than 2 meters and a height of no more than 1.5 meters; 5 holes are evenly dug on the piled manure, with a diameter of about 10 cm and a depth of about 60 cm ; Put BD502-BD506 into the hole, and ensure that BD reaches the bottom of the hole; evenly spray BD507 on the entire compost heap surface, but this method not only takes a long time to ferment and compost, but also is not conducive to large-scale industrial production

Other composting methods, such as strip piles, are to mix the raw materials and pile them into strip piles, and turn the piles regularly, and the composting can be completed after 1 to 4 months. The biggest defect of this method is that the fermentation time is long; static aeration is the use of It is a composting method in which the ventilation pipe is artificially blown and ventilated. This composting method does not allow stacking, and the composting can usually be completed in 3 to 5 weeks. Because of its moderate fermentation time and the advantages of less investment, it has a wide range of applications. The application prospect, but this method often blocks or even damages the ventilation pipe when loading and unloading materials, such as forklifts, resulting in poor ventilation, which not only prolongs the fermentation time, but also affects the quality of organic fertilizer products. Cleaning and repairing the ventilation pipe It takes a lot of manpower
