Abstract

The invention discloses a bottom air supply device of an air supply stirrer. The bottom air supply device comprises an oxygen fan, an air supply check valve, a ventilation pipeline, a flow guide pipeline and a bearing assembly, wherein an air outlet pipe of the oxygen fan and the ventilation pipeline are horizontally arranged and connected through the air supply check valve to form an air supply unit; the flow guide pipeline is internally provided with air partition plates and is divided into a plurality of separated flow guide air supply channels, and air inlets and air outlets of the flow guide air supply channels are located in the side wall and the top end of the flow guide pipeline correspondingly; and the free ends of the ventilation pipelines of the air supply units are arranged around the flow guide pipeline and connected with the air inlets of the flow guide air supply channels, and the bearing assembly is fixed to the flow guide pipeline and connected with the air outlets of the flow guide air supply channels, so that a main shaft can perform air supply while stirring. The air supply check valve can keep high synchronism with on and off of the oxygen fan. Compared with an existing butterfly valve, the air supply check valve has the advantage that manual on-off time is saved.

Description

【Technical field】 [0001] The invention relates to the technical field of fermentation tanks, in particular to the technical field of a bottom air supply device of an air supply agitator. 【Background technique】 [0002] The fermenter is an important device used in the biocomposting fermentation process. A stirrer is usually installed in the fermenter, and the stirrer generally includes a main shaft, stirring blades and a motor. Among them, the motor drives the main shaft equipped with stirring blades to rotate, so as to stir the fermentation raw materials in the tank to ensure the smooth progress of fermentation. However, the existing agitator cannot directly utilize the main shaft to simultaneously supply air during the agitation process, which is inconvenient to use. In addition, a butterfly valve is usually set at the air inlet of the fermenter to control the opening and closing of the air supply. However, the opening and closing of the butterfly valve is usually manual...
