Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, specifically a material processing fermentation tank. Background Technology

[0002] A fermenter is an industrial device used for mechanically stirring and fermenting materials. High-speed air is introduced, and the air is dispersed in the liquid in the form of bubbles. Near the ventilated area, the average density of the liquid decreases, while near the non-ventilated area, the liquid density is relatively high. This creates a density difference between the liquid in the ventilated area and the liquid in the non-ventilated area, forming a liquid circulation within the fermenter.

[0003] However, most fermentation tanks on the market currently use only a single blade at the bottom for stirring, resulting in a small stirring range. Other areas are mixed only by liquid flow, which limits the stirring effect. At the same time, the foam generated by stirring accumulates and covers the liquid surface, which not only affects the fermentation efficiency, but also easily causes a large amount of foam to accumulate and expand and overflow from the gas outlet pipe, causing pipe pollution that is inconvenient to clean. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a material processing fermentation tank that solves the problems of limited stirring effect and excessive foam accumulation on the liquid surface in current material fermentation tanks on the market, which affect fermentation efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A material processing fermentation tank includes a fermentation tank body, a drive motor is installed on the top of the fermentation tank body, the drive motor is connected to a stirring shaft disposed inside the fermentation tank body, stirring blades are fixedly installed in the middle and bottom of the stirring shaft, and a movable bubbler is movably installed on the stirring shaft above the stirring blades in the middle of the stirring shaft.

[0007] The movable foam maker includes a wear-resistant sleeve and a float that are movably sleeved on the stirring shaft. A fixing sleeve fixed to the top of the float is fixedly installed on the surface of the wear-resistant sleeve. Defoaming plates are symmetrically fixed on the surface of the fixing sleeve. The bottom of the defoaming plate is provided with a serrated groove.

[0008] The surface of the stirring shaft is symmetrically provided with vertical guide ridges above the middle stirring blade, and the wear-resistant sleeve is provided with guide grooves at the corresponding positions of the guide ridges.

[0009] Preferably, the main body of the fermenter is a temperature-controlled reaction vessel with a water bath jacket on the outer wall.

[0010] Preferably, the drive motor is a speed-regulating servo motor, and a mechanical shaft seal is provided between the bottom of the drive motor and the fermentation tank body at the position corresponding to the stirring shaft.

[0011] Preferably, the float, the fixing sleeve, and the defoaming plate are integral structures made of lightweight plastic.

[0012] Preferably, the wear-resistant sleeve is fitted with the stirring shaft and the guide ridge with a clearance fit.

[0013] Preferably, it also includes a universal inlet and outlet pipe that runs through the fermenter body and extends to the lower part of the interior, located on the side of the fermenter body, and an outlet pipe located at the top of the fermenter body.

[0014] Preferably, it also includes a sampling tube disposed on the side of the fermenter body, penetrating the fermenter body and extending to the inner middle near the inner wall, and a manhole disposed on the top of the fermenter body.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention employs a double-bladed mixing system, with upper and lower blades located in the middle and lower parts of the fermenter body, respectively. This significantly increases the mixing range and improves the mixing effect. Simultaneously, a movable bubbler is installed floating on the liquid surface, its position changing with the liquid level. The movable bubbler rotates with the mixing shaft to disperse and break up bubbles, increasing the dissolved oxygen rate and fermentation efficiency. Furthermore, it prevents foam from overflowing from the outlet pipe. This solves the problems of limited mixing effect and excessive foam accumulation on the liquid surface that affect fermentation efficiency in currently available material fermenters.
