The invention discloses a self-stirring type
biogas digester based on electro-magnetic induction. The self-stirring type
biogas digester based on the electro-magnetic induction comprises a digester body and a head cover, the head cover is located at the upper end of the digester body, a feeding
pipe is arranged on the side wall, close to the upper end, of the digester body in a communicating mode,a discharging
pipe is arranged on the side wall, close to the lower end, of the digester body, a stirring mechanism is arranged in the digester body, an
exhaust pipe is arranged on the side wall, close to the upper end, of the head cover, an installation
barrel is arranged on the upper wall of the head cover, the head cover communicates with the installation
barrel through two air holes, a drivemechanism capable of driving the stirring mechanism is arranged in the installation
barrel, the drive mechanism comprises a sliding plug, the sliding plug is slidably connected to the inner wall of the installation barrel in a sleeving mode, a
copper bar is fixedly inserted and connected to the side wall of the sliding plug, and the
copper bar is in a U shape. According to the self-stirring type
biogas digester based on the electro-magnetic induction, time of people is shortened, vigor of the people is saved, and the stirring cost is reduced; and the self-stirring type biogas digester based onthe electro-magnetic induction stirs biogas
slurry only when air pressure is lower according to the air pressure of the interior of the biogas digester, and danger cannot occur due to excessive air pressure in the biogas digester.
