Description

Special stirrer for biogas fermentation Technical Field The utility model relates to the technical field of biogas fermentation, in particular to a stirrer special for biogas fermentation. Background Biogas fermentation is a technology for producing combustible gas by utilizing organic waste under anaerobic condition through the action of microorganisms, and is widely applied to the fields of agriculture, aquaculture, urban sewage treatment and the like, and is an important means for recycling and energy recovery. Biogas fermentation equipment plays an important role in the process, and as one of core components, the stirring effect of the biogas fermentation equipment has a decisive influence on fermentation efficiency, gas production rate and stability of the whole system. Particularly in the core link of stirring, the conventional stirring device gradually exposes a series of obvious limitations and technical problems when processing fermentation materials with high viscosity and high solid content. For example, the utility model patent CN220907474U discloses a stirring mechanism based on biogas fermentation, which comprises a fermentation tank, a driving mechanism and a stirring mechanism, wherein the stirring mechanism enlarges the stirring range and improves the stirring efficiency through the design of a movable block, a pneumatic cylinder, a connecting rod and a scraper. Although the structure improves the stirring effect to a certain extent and can clean the inner wall of the tank body, obvious defects still exist in practical application. Specifically, the existing stirring equipment has the prominent problems of uneven stirring, low mixing efficiency and the like in the stirring process. Because the biogas fermentation material generally has the characteristics of high viscosity and poor fluidity, local accumulation or caking phenomenon is easy to form in the stirring process, so that the material is insufficiently contacted with microorganisms, and the fermentation efficiency is affected. In addition, the stirring range of the existing stirrer is limited, the bottom and edge area of the fermentation tank cannot be effectively covered, stirring blind areas are caused, and the problem of uneven material distribution is further aggravated. Therefore, in order to solve the problems of the prior art, an innovative stirrer special for biogas fermentation is urgently needed.
