Self-stirring type biogas digester based on electro-magnetic induction

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of biogas fermentation equipment, in particular to a self-stirring biogas digester based on electromagnetic induction. Background technique [0002] Biogas refers to a flammable gas produced by microbial fermentation of organic matter. Biogas digesters are built in many rural areas. Biogas digesters have played a great role in improving the rural environment, and biogas can be produced through the fermentation of manure , It can also produce a large amount of organic fertilizer, which promotes the development of agriculture. [0003] However, if the biogas slurry in the biogas digester wants to fully react, it needs to be stirred. Manual stirring requires a lot of time and energy, and the work efficiency is low. It needs to consume a lot of electric energy, and the cost is too high. Moreover, the motor and other devices cannot stir according to the air pressure in the biogas tank. A self-stirring biogas di...
