Embodiment Construction
[0011] In the tank-type anaerobic and aerobic fermentation to produce biogas and organic fertilizer, one end of the reinforced concrete structure of the fermentation tank is closed, and the other end is open, that is, the top and one end of the tank are open. Using the continuous process of anaerobic fermentation and aerobic fermentation, the upper surface of the tank and one end surface must be sealed for anaerobic fermentation and open for aerobic fermentation. The problem can be solved by adopting the present invention.
[0012] figure 1 , figure 2 It is a schematic diagram of the present invention, a U-shaped groove 1-1 is provided in the rigid container 1, and the edge of the flexible covering material 2 is put in close to the U-shaped groove 1-1, and the hose 3 is embedded in the U-shaped groove 1-1, and pressed against the U-shaped groove 1-1. Flexible cover material 2 on. Close the hose deflation valve 3-2 tightly, fill the hose 3 with a certain pressure of gas fro...
