Semi-buried biogas mixed jacking fluffy soft body anaerobic fermentation system

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a semi-buried anaerobic fermentation system for biogas mixing and jacking fluffy soft body to solve the problems of the fermentation tank due to the anaerobic fermentation of biogas that needs to be buried in the septic tank. The semi-buried docking will form the upper part to circulate air and the lower part to absorb biogas fermentation effect, but the fully enclosed work in the anaerobic process will cause the software to separate the upper and lower air pressure after twisting, resulting in continuous expansion and compression of the lower air pressure. On the other hand, the circulating air on the upper road will squeeze the left and right outer rows along the top of the soft arc, causing the super-density compression of the biogas to easily cause explosion hazards, and after fermentation after sealing, when people need to dismantle the tank cover for inspection, the cover will be turned upside down and crushed. Due to the situation of personnel, the pressure difference between the internal and external environment cannot be properly handled, which affects the problem of the ratio of the loading capacity and the gas collection capacity in the fermentation space.
