Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizer preparation, and in particular to an organic fertilizer secondary aerobic fermentation device and a preparation method. Background Art

[0002] In order to avoid the secondary pollution of the atmospheric environment by odorous gases in the traditional open aerobic fermentation process, a fully enclosed fermentation tank is used for aerobic fermentation of organic fertilizer. The aerobic fermentation process of organic fertilizer is the process in which various fermentation bacteria degrade large molecular structures into small molecular structures and transform them into stable humus. The traditional open aerobic fermentation cycle is usually about 45 to 60 days, while the fermentation cycle of a fully enclosed fermentation tank can be reduced to less than 30 days. Fully enclosed fermentation is to place the entire fermentation process in a fully enclosed fermentation tank, and a large amount of oxygen needs to be provided. Therefore, all equipment related to fully enclosed fermentation needs to use pressure-resistant equipment, the equipment investment cost will increase significantly, and the investment return ratio will be greatly reduced. In the early stage of feces fermentation, the fully enclosed fermentation tank can completely seal the malodorous gases produced in the early stage of fermentation in the tank body, and as the fermentation process progresses, the malodorous gases are absorbed and converted into elements required for plant growth. Most of the malodor of the fermented material will disappear within two days, and the fermentation temperature is usually maintained above 55°C for 5 days, which can meet the needs of high-temperature killing of harmful bacteria and grass seeds. Therefore, for the fully enclosed aerobic fermentation with a full cycle of 30 days, the time of fermentation materials in the fully enclosed fermentation tank only needs to be controlled at 5 to 7 days. At this time, the malodor of the fermented material has completely disappeared and replaced with a slightly earthy smell. At the same time, the killing of harmful bacteria and grass seeds is also ensured. Therefore, while ensuring near-zero pollution to the environment, the rest of the time can be transferred to other equipment for aerobic fermentation, reducing the number and investment of fully enclosed fermentation tanks, improving the working efficiency and processing capacity of fully enclosed fermentation tanks, and reducing costs.

[0003] After searching, the invention with application number CN201920992425.3 in the prior art discloses a device for secondary aerobic fermentation of organic fertilizer, including an oxygen generator, a fermentation tank body, a fermentation tank top cover, a flexible air pipe, a hanging rope, a pulley, an air collecting pipe, a motor, a spray absorption tower, a spray head, a blower, an induced draft fan, a circulation pump, a circulation pipe, a material receiving trough, a belt conveyor, an oxygen pipe, a hydraulic push rod, a support frame, a bottom plate, etc.; after the organic fertilizer fermentation in the fully enclosed fermentation tank ends the initial stage, a more economical device for secondary aerobic fermentation of organic fertilizer is used to improve the working efficiency and processing capacity of the fully enclosed fermentation tank, reduce the total investment of the fermentation equipment, and make full use of the three-dimensional space of the fermentation workshop to realize a three-dimensional layout and highly automated organic fertilizer fermentation device under more economical conditions.

[0004] However, since it does not have a stirring mechanism, the organic fertilizer in the secondary aerobic fermentation cannot fully contact with oxygen, and the secondary aerobic fermentation effect is not good. In addition, due to the lack of a temperature control mechanism, the organic fertilizer in the secondary aerobic fermentation cannot be kept at a suitable temperature for a long time, resulting in low secondary aerobic fermentation efficiency.
