Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tank accessories, in particular to an aeration structure of an aerobic fermentation tank. Background Art

[0002] With the development of society, national and local governments are paying increasing attention to environmental pollution issues. Livestock and poultry manure pollution is a top priority in agricultural environmental pollution control. Traditional manure disposal methods, such as direct removal to fields or fermentation in troughs, can easily cause groundwater, soil, and air pollution. Therefore, the development of an effective manure treatment technology is particularly important. To address the environmental pollution problems caused by livestock and poultry farming, aerobic fermenters suitable for livestock and poultry manure have emerged to convert poultry manure into organic fertilizer through fermentation, achieving resource recycling and environmental protection. However, existing aerobic fermenters have defects in their aeration structures, resulting in loss of air output and uneven air output between the upper and lower tank bodies. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides a novel aeration structure for an aerobic fermentation tank for livestock and poultry manure, which facilitates the aeration of the fermentation tank and ensures more uniform fermentation.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] An aeration structure for an aerobic fermentation tank comprises: a stirring main shaft arranged in the aerobic fermentation tank body, the stirring main shaft comprising a detachable lower end shaft head and an upper end shaft head; a first aerator and a second aerator are connected to the bottom of the lower end shaft head; a first blade layer and a second blade layer are distributed on the lower end shaft head; a seal is provided in the lower end shaft head at the second blade layer, and a ventilation pipe is connected between the seal and the second aerator.

[0006] Furthermore, the sealing component includes an upper wind shield, a lower wind shield, a sealing ring arranged between the lower wind shield and the ventilation duct, and a sealing plate abutting against the sealing ring.

[0007] Furthermore, the lower wind shield has an opening in the middle to allow air to pass to the second blade layer.

[0008] The beneficial effects of the utility model are as follows: the present application improves the aeration structure of the existing stirring device, and two groups of aerators are arranged at the bottom of the stirring device. The main aerator supplies air to the inside of the main shaft, and the other group of aerators is connected to the upper blades, so that the aeration inside the main shaft is layered, and the gas supply can be evenly distributed. At the same time, a seal is provided to avoid loss of air output and improve the aeration efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
