Embodiment 1

[0027] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a self-rotating air injector is installed at the bottom of the biological fermentation tank. An air inlet pipe 1 is installed at the bottom 6 center of the biological fermentation tank to be connected with the air delivery pipe outside the fermentation tank. There are four air outlet branch pipes 2 equidistantly arranged on the top, and each air outlet branch pipe is located on the same horizontal plane, and the air outlet branch pipes are radially evenly distributed with three branch pipes 3, and a nozzle with an adjustable direction and angle is installed on each branch pipe 4. The direction of the nozzle 4 is adjusted to the concentric circle formed when the injector rotates, facing the opposite direction of the injector's rotation direction. The upper end of the air intake pipe is provided with an upper shaft sleeve 7, and the lower end of the air intake pipe and the bottom of the tank 6 have a lower ...

Embodiment 2

[0029] Such as Figure 6 , Figure 7 As shown, the upper end of the air intake pipe 1 is equipped with a coupling 9, the coupling is connected with the stirring shaft 5, and the lower end of the air intake pipe 1 and the bottom of the tank 6 have a lower bushing 8. The air launcher rotates coaxially with the stirring shaft. For large-capacity biological fermentation tanks.

[0030] The parts not described in embodiment 2 are the same as in embodiment 1.

Abstract

The invention relates to a microbial fermentation device, and in particular relates to an air ejector with own power rotation arranged at the bottom of a biological fermentation tank. The air ejector has the following structural features: an air inlet pipe connected with an air delivery pipe outside a fermentation tank is arranged in the center of the bottom in a tank body; a plurality of air outlet branch pipes are arranged at equal intervals on the circumference of the pipe wall of the air inlet pipe, and are positioned on the same horizontal plane; branch pipes of a plurality of branches are distributed in the radial direction of the air outlet branch pipes; and a nozzle arranged on the branch pipe of each branch has an adjustable direction angle. The air ejector provided by the invention has the following beneficial effects: during rotation, the air ejector ejects out air to strengthen gas-liquid mixing, thereby improving the utilization ratio of oxygen in the air; and moreover, the air ejector achieves a boosting effect, reduces the kinetic power, and achieves an aim of low energy consumption.

Description

technical field [0001] The invention relates to a microbial fermentation device, in particular to a self-rotating air injector installed at the bottom of a biological fermentation tank. Background technique [0002] During the whole process of cultivating and growing oxygen-enriched microorganisms in the fermenter, it needs power to drive the stirring device, strengthen the gas-liquid mixing, and constantly replenish fresh sterile air to absorb oxygen from the air to promote the growth of microorganisms. [0003] At present, the fermenter equipment equipped in the biopharmaceutical industry is limited by many conditions, such as the power consumption of power stirring and the utilization of oxygen in the air. It is difficult to meet the needs of the current microbial fermentation process. Therefore, corresponding technical improvements should be made to the existing biological fermenter device so that it can be effectively improved. Contents of the invention [0004] The ...
