Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, in particular to a fermentation tank with a turnover mechanism. Background Art

[0002] The fertilizer fermentation tank is an environmentally friendly technical facility designed to convert agricultural waste, livestock and poultry manure and other organic matter into high-efficiency biological organic fertilizer through natural biological processes. This process not only processes a large amount of organic waste and reduces environmental pollution, but also promotes the recycling of resources and enhances the sustainability of the agricultural ecosystem. The working principle of the fermentation tank is based on the activity of microorganisms. These microorganisms decompose the organic materials put into the tank under suitable temperature, humidity, pH and ventilation conditions. With the metabolism of microorganisms, organic matter is gradually degraded into smaller molecules, such as amino acids, peptides and various soluble organic acids, which are easier for plants to absorb and utilize. During this process, microorganisms also generate heat, which helps maintain the temperature required for fermentation and accelerates material conversion.

[0003] Traditional fermentation tanks often have a simple structure and lack an effective oxygen supply system, which directly limits the activity and efficiency of aerobic microorganisms within the tank. Since oxygen is an essential element for aerobic microorganisms to decompose organic matter, insufficient oxygen supply will cause fermentation to tend towards an anaerobic or microaerobic state, affecting the thoroughness and speed of fermentation. Although fermentation reactions can still occur in anaerobic or low-oxygen environments, this method tends to produce more harmful gases such as hydrogen sulfide and ammonia rather than the desired carbon dioxide and water. How to invent a fermentation tank with a turnover mechanism to improve these problems has become a pressing issue for those skilled in the art. Utility Model Content
