The invention discloses a shaft ventilation type efficient stirrer, and relates to the technical field of stirring equipment.The shaft ventilation type efficient stirrer comprises a tank body, a sealing plate is arranged at an opening in the upper end of the tank body, a feeding port is formed in the sealing plate, and a discharging port is formed in the bottom of the tank body; the bracket is used for bearing the tank body; the center shaft is rotationally arranged at the axis of the sealing plate, the upper end of the center shaft is located above the tank body, the top of the center shaft is communicated with an air source, and the lower end of the center shaft is located in the tank body; the driving
assembly is arranged at the upper end of the sealing plate and used for driving the center shaft to rotate; through the three layered
aeration units, comprehensive
aeration of materials on the upper layer and the lower layer of the tank body is achieved, the defect that existing equipment can only conduct bottom
aeration is overcome, meanwhile, the design that the hole
diameter is gradually reduced from top to bottom is adopted in a center shaft
airflow channel, step-by-step pressurization is achieved in the gas flowing process, the aeration efficiency is improved, and the aeration efficiency is improved. The air outlet resistance caused by lower-layer
water pressure is effectively counteracted.
