The utility model discloses a mechanical stirring ventilation
fermentation tank, which relates to the technical field of
fermentation tanks, and comprises a tank body, a pressure gauge, a support and a jacket, the pressure gauge is arranged at the top of the tank body, the support is arranged at the bottom of the tank body, the jacket is arranged outside the tank body, a motor is arranged at the top of the tank body, and the motor is connected with the pressure gauge. An output shaft of the motor is fixedly connected with a stirring shaft, the top of the tank body is communicated with a ventilation
pipe, the end, located in the tank body, of the ventilation
pipe is fixedly connected with a guide hopper, and the end of the ventilation
pipe is fixedly connected with a connecting column. A stirring shaft, a guide hopper, a connecting column, an extension rod, a spring, a dispersion plate and other parts are arranged in the tank body, when the stirring shaft stirs
viscous liquid in the tank body, the
viscous liquid is prevented from splashing to a vent pipe opening to affect the ventilation effect, when air enters the tank body from a vent pipe, the dispersion plate can disperse the air, the ventilation structure is optimized, and the ventilation effect is improved. And the ventilation effect is better.
