Fermentation tank with air distributor

Abstract

The invention provides a fermentation tank with an air distributor, belongs to the technical field of fermentation tanks and solves the problem that the fermentation liquid in the existing fermentation tank is not uniformly mixed with the air. The fermentation tank with the air distributor comprises a tank body, wherein the air distributor is located at the bottom of the tank body and comprises a necking pipe, a shunting pipe and a nozzle; the necking pipe is fixedly connected to the tank body; the upper part and the lower part of the necking pipe are conical flaring-shaped; the shunting pipe is conical; the shunting pipe is fixed into the upper part of the necking pipe; a plurality of through holes are formed in the shunting pipe at intervals; a gap is defined between the shunting pipe and the upper part of the necking pipe; an air outlet of the nozzle is located in the lower part of the necking pipe; an air inlet of the nozzle is located outside the tank body; a gap is defined between the nozzle and the lower part of the necking pipe. The fermentation tank with the air distributor has the advantage of uniformly mixing the fermentation liquid with the air.

Description

technical field [0001] The invention belongs to the technical field of fermentation tanks and relates to a fermentation tank with an air distributor. Background technique [0002] Fermentation tanks are an important part of equipment used in research in the fields of biomedicine and microbial fertilizers. During the fermentation process, aerobic microorganisms need to provide continuous and uniform oxygen to the fermentation tanks. [0003] Existing fermentation tanks, such as Chinese patent documents disclose an air-lift stirring fermentation tank [application number: 201520034006.0; authorization announcement number: CN204569910U], which includes a tank body, the bottom end of the tank body is provided with an air inlet nozzle, and the top end of the tank body An air outlet is provided; a tension cylinder is arranged vertically inside the tank; several jackets are arranged outside the tank; one end of the air inlet connection in the tank is connected to the air nozzle; the...

AI Technical Summary

Problems solved by technology

[0004] In the fermenter of this structure, the contact area between the air and the fermentation liquid is increased by making the nozzle into a spherical shape, and the amount of dissolved oxygen in fermentation is increased; but the air ejected from the air nozzle of this structure can only interact with the nearby fermentation liquid. Mixing, the sprayed air cannot drive the fermentation liquid in the fermenter to flow well, that is, the air is not mixed evenly with the fermentation liquid in the fermenter, resulting in poor fermentation effect of the fermenter
