Description
Technical field
The invention belongs to technical field of biological fermentation, and in particular to a kind of machinery for biological fermentation tank is stirred
Mix device.
Background technology
At present, microbial fermentation is widely used in various industries such as chemical industry, medicine and food.Seeding tank and
Main fermentation tank is the key equipment during production, and generally constant rotational speed mechanical agitation container is due to micro- life
Thing is very sensitive to the shearing force that stirring is produced, so speed of agitator control ratio is stricter, it is impossible to too high.
In addition, flourishing with Chinese biological technology industry, fermentation tank maximizes increasingly, and agitating shaft is not yet
It is disconnected to lengthen, become apparent the resonance problem of such axle, to solve the generation of covibration, engineering practice
In it is much more general using increasing the diameter of axle or increase supporting-point, but so place comprehends and brings some to adversely affect：Cross
The increasing diameter of axle (solid shafting) is divided to not only increase axoplasm amount, and effect is not also obvious, because solid shafting
By it is curved, turn round when, the material of center section is not fully used；The excessive supporting-point that increases can increase
The microbiological contamination chance of biological fermentation tank.Therefore, the optimization design of agitating shaft is significant.
Meanwhile, the structure design of bioreactor depends on the stream in experience, but fermentation whipping process
Field is that extremely complex, general design is often difficult to reach expected design effect.Accurate simulation and retouch
The mobility status and mixed process in fermentation tank are stated, is the difficult point of bioreactor design.The oar of agitator
Leaf form mainly has radial flow agitator and axially stream agitator.In fermentation arts, radial flow agitator
The characteristics of be that gas dispersibility is strong, simple structure, but power consumption is larger, sphere of action is limited, axially stream
Agitator is preferable, low in energy consumption to the material mixed performance in fermentation process, but its weak point is to gas
The dispersibility of body is poor, because the volume scale of modern fermentation tank constantly expands, depend alone individual layer blade or
The need for the agitator of blade form can not meet industrial production, therefore the multilayers of two kinds of flow patterns of combination,
Combined blender arises at the historic moment.
The content of the invention
It is above-mentioned to solve it is an object of the invention to provide a kind of mechanical agitator for biological fermentation tank
The problem proposed in background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of machine for biological fermentation tank
Tool agitator, including motor, speed-changing gear box and agitating shaft, the motor are nibbled with speed-changing gear box
Connection is closed, the speed-changing gear box is rotated with agitating shaft and is connected, and the agitating shaft is fixed successively from top to bottom
There is spiral to overturn blade, turbine stirring leaf, New type agitation oar and hexagonal turbine stirring leaf, the agitating shaft
Inside be set to cavity.
Preferably, the motor is provided with frequency converter.
Preferably, the spiral upset blade is circumferentially positioned on the circumference of agitating shaft.
Preferably, the hexagonal turbine stirring leaf is arranged on the bottom of agitating shaft.
Technique effect of the invention and advantage：This is used for the mechanical agitator of biological fermentation tank, and traditional
Mechanical agitator, in the fermentation tank of industrialized production, longer axis (single span axial length L >=4000mm)
Critical speed is the Con trolling index of the agitating shaft diameter of axle, the solid shafting of same external diameter is replaced with hollow shaft, significantly
The consumption of steel is reduced, while also making its critical speed improve, axle is more long, and effect is brighter
It is aobvious；When its fermenter base of the invention is passed through gas, the hexagonal turbine stirring leaf installed in bottom is by gas
Minute bubbles are dispersed as, increase the contact area of gas-liquid two-phase；It is mixed using New type agitation oar and turbine stirring leaf
The characteristics of conjunction performance is good, makes whole liquid into loop cycle, and gas-liquid mixed is realized on a large scale, fully profit
With four groups of advantages of agitator, learn from other's strong points to offset one's weaknesses, be large-scale fermentation from now on using multilayer, combined type paddle
One developing direction of tank design.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the invention, and
It is not all, of embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under the premise of creative work, belong to the scope of protection of the invention.
The invention provides a kind of mechanical agitator for biological fermentation tank as Figure 1-4, including
Motor 1, speed-changing gear box 2 and agitating shaft 3, the motor 1 are provided with frequency converter, described electronic
Machine 1 is connected with the engagement of speed-changing gear box 2, and the speed-changing gear box 2 is rotated with agitating shaft 3 and is connected, institute
State agitating shaft 3 and be fixed with spiral upset blade 4, turbine stirring leaf 5, New type agitation oar successively from top to bottom
6 and hexagonal turbine stirring leaf 7, the spiral upset blade 4 is circumferentially positioned on the circumference of agitating shaft 3,
The hexagonal turbine stirring leaf 7 is arranged on the bottom of agitating shaft 3, and its fermenter base of the invention is passed through gas
During body, gas is dispersed as minute bubbles by the hexagonal turbine stirring leaf 7 installed in bottom, increases gas-liquid two-phase
Contact area；The characteristics of using New type agitation oar 6 and turbine stirring 5 good mixing property of leaf, make whole
Liquid realizes gas-liquid mixed on a large scale into loop cycle, makes full use of four groups of advantages of agitator, takes
Benefit long is short, is the developing direction that large fermentation tank is designed from now on using multilayer, combined type paddle；
The inside of the agitating shaft 3 is set to cavity 8, and traditional mechanical agitator, by hollow shaft and solid shafting
Contrast, the critical speed of longer axis (single span axial length L >=4000mm) is the control of the diameter of axle of agitating shaft 3
Index processed, the solid shafting of same external diameter is replaced with hollow shaft, drastically reduce the area the consumption of steel, while
Its critical speed is set to improve, axle is more long, and effect is more obvious.
