Large-scale high-mass-transfer circulating type ventilation fermentation tank

Abstract

The invention discloses a large high-mass-transfer circulating type ventilation fermentation tank which structurally comprises a support, a tank body and a motor, the tank body is vertically welded tothe top of the support, the motor is vertically installed in the center of the top of the tank body, and the tank body is provided with a liquid inlet pipe, a liquid outlet pipe, a dispersing plate,a sleeve and a pushing mechanism. The liquid inlet pipe penetrates through the left side of the bottom of the tank body, fermentation broth is continuously blocked by fermentation broth solids due tothe fact that the fermentation broth precipitates downwards under the gravity of the fermentation broth and is easily stacked at the top end of the liquid inlet pipe, the fermentation solids retainedat the top of the liquid inlet pipe are pushed through the pushing mechanism, the solids stacked at the top end of the liquid inlet pipe are reduced, continuous introduction of the fermentation brothis facilitated, and the fermentation speed is increased; due to the fact that fermentation liquid in the tank body easily flows back into the liquid inlet pipe through the opening, the swing plate inthe opening is movably matched with the fermentation liquid, the fermentation liquid in the tank body can be easily blocked, backflow of the fermentation liquid into the liquid inlet pipe is reduced,an appropriate amount of the fermentation liquid in the tank body can be easily kept, and mixed fermentation of the fermentation liquid and fermentation substances is accelerated.

Description

technical field [0001] The invention belongs to the field of mechanically stirred ventilated fermentation tanks, and more specifically relates to a large-scale high-mass-transfer circulating ventilated fermentation tank. Background technique [0002] Circulating ventilated fermentation mixes the fermented material with the fermented liquid. During the circulation process, the fermented liquid obtains oxygen consumption. The fermented liquid is fed into the liquid inlet pipe at the bottom of the tank, and the fermented material is stirred through the dispersing plate in the fermenter and the oxygen is diffused. , so that the fermented substance fully reacts with oxygen. When the liquid level of the fermented liquid is higher than the sleeve inside the tank when stirring, the fermented liquid passes along the sleeve and returns to the bottom of the tank; At this time, because part of the fermented product is a round solid shape, when the fermented product is continuously pushe...

[0002] Circulating ventilated fermentation mixes the fermented material with the fermented liquid. During the circulation process, the fermented liquid obtains oxygen consumption. The fermented liquid is fed into the liquid inlet pipe at the bottom of the tank, and the fermented material is stirred through the dispersing plate in the fermenter and the oxygen is diffused. , so that the fermented substance fully reacts with oxygen. When the liquid level of the fermented liquid is higher than the sleeve inside the tank when stirring, the fermented liquid passes along the sleeve and returns to the bottom of the tank; At this time, because part of the fermented product is a round solid shape, when the fermented product is continuously pushed upward by the liquid, the fermented product will settle down under its own gravity, and it will easily pile up on the top of the liquid inlet pipe, causing the fermented liquid to be constantly affected by the fermented product. Blocked by solids, the fermentation broth is intermittently introduced, which slows down the fermentation speed
