Abstract

The invention belongs to the technical field of biogas digesters, and particularly relates to a self-circulation fermentation biogas digester for animal husbandry. The self-circulation fermentation biogas digester comprises a fermentation tank, a top cover, a fixed disc, a protective cover, a motor, a first belt wheel, a second belt wheel, a belt, a rotating shaft, a spiral blade and a cutting device. The motor is controlled to drive the rotating shaft to rotate, the rotating shaft drives the spiral blade to rotate, the spiral blade spirally ascends along the rotating shaft, the spiral blade drives excrement to move upwards along the rotating shaft, the excrement in the middle of the fermentation tank is conveyed to the top of the fermentation tank along with the rotation of the spiral blade, then flows to corners around the fermentation tank, moves to the bottom of the fermentation tank and finally flows to the middle of the fermentation tank, the excrement is driven by the spiral blade to circularly flow, the excrement in the fermentation tank is fully mixed in the process, fermentation of the excrement in the fermentation tank is facilitated, the decomposition speed of the excrement is increased, biogas yield stability is guaranteed, and normal use of users is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of biogas digesters, in particular to a self-circulating fermentation biogas digester for animal husbandry. Background technique [0002] Biogas digesters are used to produce biogas. Biogas is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain temperature, humidity, and pH conditions. Therefore, biogas is a cheap and high-quality fuel. The waste from the biogas digester is biogas slurry and biogas residue, which can be used as pesticide additives, fertilizers, feed, etc., which greatly reduces the harm caused by chemical fertilizers and pesticides, and is conducive to the production of green and pollution-free products. [0003] Animal husbandry is one of the components of agriculture, and it is listed as the two pillars of agricultural production along with planting. Animal husbandry produces a large amount of excrement. If the excrement is dis...
