Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fermentation tank, concretely to a biological molecule industrial fermentation tank. BACKGROUND

[0002] In the field of biological molecule industrial production, the fermentation tank is one of the core equipment, and its performance directly affects the fermentation efficiency of biological molecules, product quality and production cost. The microbial fermentation process has extremely harsh requirements on environmental conditions, and the mixing effect of the fermentation broth is a key factor. Suitable stirring mode can ensure the uniform distribution of nutrients, microorganisms and dissolved oxygen in the fermentation broth, provide a suitable environment for the growth and metabolism of microorganisms, and thus promote the efficient synthesis of biological molecules.

[0003] Most of the traditional fermentation tank blades are of fixed structure, and the stirring intensity and mode are single, which is difficult to meet the diversified demand of stirring in different fermentation stages and different fermentation processes. In the early stage of fermentation, the microorganisms grow slowly, and only gentle stirring is needed to preliminarily mix the nutrients, so as to avoid damage to the microorganisms caused by excessive stirring. However, the existing fixed blades often have too large stirring intensity in this stage, which not only consumes too much energy, but also may destroy the growth environment of the microorganisms. In the middle and later stages of fermentation, with the increase of the number of microorganisms and the intensification of metabolic activity, stronger stirring is needed to promote the sufficient mixing of nutrients and the transmission of dissolved oxygen. At this time, the fixed blades cannot provide enough shear force and convection effect, resulting in uneven distribution of nutrients in the fermentation broth, too high or too low local nutrient concentration, affecting the growth and metabolism of microorganisms, and thus reducing the fermentation efficiency and the stability of product quality. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing a biological molecule industrial fermentation tank to solve the problem of the limitation of the fixed blades of the conventional fermentation tank in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a biological molecule industrial fermentation tank, comprising a tank body, a driving device and a hollow shaft arranged in the inner cavity of the tank body, a pair of fixed sleeves are fixedly installed on the outer wall of the hollow shaft, a plurality of fixed blades distributed in a circle are fixedly installed on the side wall of the fixed sleeve, rotating blades are rotatably installed at the end of the fixed blade, the rotating blade and the fixed blade are connected through an elastic member, an electric telescopic rod is fixedly installed in the inner cavity of the hollow shaft, a pair of discs are fixedly installed on the output end of the electric telescopic rod, the bottom of the rotating blade penetrates the hollow shaft through a pull rope and is fixedly connected with the disc, so that the output end of the electric telescopic rod drives the disc to make vertical motion, and the rotating blade is driven to rotate and adjust the angle by cooperating with the pull rope.

[0006] Preferably, a plurality of round holes for the pull rope to penetrate are arranged on the side wall of the hollow shaft.

[0007] Preferably, the elastic member is a tension spring, and two ends of the tension spring are respectively connected with the fixed blade and the rotating blade.

[0008] Preferably, the hollow shaft is assembled by a pair of arc-shaped sheets, and an inner wall of one of the arc-shaped sheets is fixedly provided with a partition plate, and an end of the electric telescopic rod is fixedly provided on the partition plate.

[0009] Preferably, the end of the fixed blade is integrally provided with a protruding portion.

[0010] Preferably, the bottom of the hollow shaft is provided with a plurality of water outlets.

[0011] Compared with the prior art, the beneficial effects of the present application are:

[0012] The present application is assembled by the electric telescopic rod, the fixed blade, the rotating blade, the pull rope and the tension spring in the tank body to form an adjustable paddle, so that different mixing effects can be achieved under different stirring intensities. When the fixed blade and the rotating blade are flush during slight stirring, the nutrients in the fermentation liquid can be preliminarily mixed uniformly to provide a relatively stable growth environment for microorganisms. When the rotating blade is inclined during strong stirring, stronger shear force and convection effect can be generated to more fully mix the materials in the fermentation liquid, avoid local high or low nutrient concentration, and ensure that microorganisms can contact sufficient nutrients in the whole fermentation system, which is beneficial to improving the fermentation efficiency and the stability of product quality.
