Description

Technical Field

[0001] The present invention relates to a production line system for microbial fertilizer production, belonging to the technical field of microbial fermentation equipment. Background Art

[0002] Microbial fertilizer is developed based on the principles of soil microecology, plant nutrition, and the basic concept of modern "organic agriculture". Microbial fertilizer is a new type of fertilizer biological product in which the life activities of active (reproducible) microorganisms lead to crops obtaining the required nutrients (fertilizers), and it is a type of fertilizer in agricultural production (also known as the third-generation fertilizer).

[0003] Microbial fertilizer is suitable for various crops. It can activate nutrients, improve nutrient utilization rate, and has universality, breaking the inherent weaknesses of "specificity", "limitation", and "special fertilizer" of ordinary biological fertilizers, which is incomparable to other biological fertilizers. It can be applied to various types of soil. Generally speaking, microbial fertilizer can be used to improve soil and reduce the use of chemical fertilizers to promote crop growth on any land where plants grow. Microbial fertilizer has the functions of improving soil fertility, increasing the number and activity of beneficial microorganisms in the soil, improving the activated properties of the soil, preventing soil compaction; improving the soil's fertilizer and water retention, cold resistance, quickly multiplying to form beneficial microbial populations to enhance the disease resistance of crops; increasing the organic matter in the soil, preventing the invasion of pathogenic bacteria, reducing the growth of plant diseases and pests, promoting the growth of crops, increasing crop yields, and improving and restoring the quality of agricultural products.

[0004] The core of microbial fertilizer production is the cultivation of active microbial bacteria, which is fermented and cultured through a set of microbial fermentation production lines (abbreviated as microbial factories). During the microbial fermentation process, there are anaerobic fermentation and aerobic fermentation. Among them, the fermentation tank system technology for aerobic fermentation is very mature. However, for anaerobic fermentation, issues such as how to achieve anaerobic control of the fermentation tank, how to achieve the emission of fermentation tail gas, how to achieve the pressure balance inside the anaerobic fermentation tank, and how to overcome the shear stress of the fermentation tank stirring mechanism need to be further studied and solved. In addition, the pH value of the fermentation system needs to be controlled. Usually, ammonia water or liquid caustic soda is added. Ammonia water occupies a large storage volume and is easy to volatilize, causing environmental pollution and personal injury; liquid caustic soda is usually purchased in the form of flake caustic soda and used as it is prepared. The appropriate concentration can be configured according to needs. The usual method is to add flake caustic soda to water and stir to dissolve it. However, a large amount of heat is usually released during the dissolution process, posing safety hazards. Therefore, a caustic soda solution tank device that separates caustic soda from water and dissolves it dynamically is needed to achieve efficient and automated operation.

[0005] Furthermore, after the active microbial bacteria are fermented and cultured, it is necessary to further add trace elements such as N, P, and K, and finally through compounding, the finished microbial fertilizer is obtained. The present invention aims to solve the aforementioned technical problems and designs a production line system to achieve the automated and efficient production of microbial fertilizers.
