Description

Technical Field

[0001] This utility model relates to the field of anaerobic fermentation technology, and in particular to an anaerobic fermenter. Background Technology

[0002] Anaerobic digesters are core equipment that decompose organic waste into biogas and organic residues in a closed environment by utilizing the metabolic activities of anaerobic microorganisms. They are widely used in energy production, waste treatment and environmental protection. The core of anaerobic digesters is to create a stable anaerobic environment for microorganisms, and complete the degradation of organic matter through multi-stage synergistic metabolism of microorganisms.

[0003] The applicant has discovered that existing technologies suffer from at least the following technical problems: Traditional anaerobic digesters often lack targeted material pretreatment structures, or the crushing rate in the pretreatment stage is fixed and cannot be adjusted. When processing organic materials of different particle sizes and hardnesses, such as coarse straw and soft manure, the fixed-rate crushing mechanism cannot adapt to the material characteristics. Insufficient crushing of coarse materials can easily lead to uneven mixing of materials and insufficient contact area between microorganisms and organic matter during subsequent fermentation, thus reducing degradation efficiency. For soft materials, over-crushing may occur, increasing energy consumption and easily causing screen blockage, affecting the material conveying and screening process. Utility Model Content
