[0003] The existing biogas fermentation tanks have low stirring efficiency. Generally, biogas fermentation tanks are equipped with stirring mechanisms to ensure uniform fermentation of raw materials. The stirring mechanisms stir the raw materials by rotating a stirring rod driven by a motor. This stirring mechanism has a single stirring direction and low stirring efficiency. It is difficult to quickly stir the raw materials evenly, which affects the quality of fermentation and is also inconvenient to clean the solar panels. Generally, biogas fermentation tanks use solar power generation to save energy. Solar panels are generally installed on the top of the fermentation tank. After long-term use, a large amount of dust will adhere to the solar surface, affecting the efficiency of power generation and requiring cleaning. Since the solar panel is installed on the top of the fermentation tank, when cleaning, the staff needs to climb up the fermentation tank and use tools such as brushes to clean it, which is very troublesome, increases the workload, reduces the cleaning efficiency, and is inconvenient to use. In order to solve the above problems, we propose a biogas fermentation tank with a pressure protection component. Utility Model Content
