Description

Technical Field

[0001] The utility model relates to the technical field of fermentation machines, in particular to a film-covered livestock and poultry excrement aerobic composting fermentation machine which is convenient for mixing materials. Background Art

[0002] At present, the treatment of livestock and poultry manure is an important part of agricultural waste management. The traditional treatment method is mainly open-air composting, but there are problems such as odor pollution, soil and water pollution. In order to solve these problems, the film-covered livestock and poultry manure aerobic composting fermentation machine came into being. The film-covered livestock and poultry manure aerobic composting fermentation machine is a device specially used for treating livestock and poultry manure. It promotes the decomposition and composting fermentation process of organic matter in livestock and poultry manure by controlling factors such as temperature, humidity and ventilation. The equipment can efficiently convert livestock and poultry manure into organic fertilizer and can effectively reduce the release of odor and pollutants.

However, the sandbag sealing operation is cumbersome and the sealing is not easy to ensure, which leads to gas leakage and environmental pollution. In addition, the horizontal air supply pipe is laid on the ground, which will cause the air supply head to be limited, the air distribution to be inadequate, and the intermediate fermentation to be incomplete, thereby reducing the quality and efficiency of the fermentation.
