Abstract
The invention discloses a trapezoidal blade stirring paddle with peripheral teeth and relates to blades of stirring paddles. The trapezoidal blade stirring paddle with peripheral teeth comprises a hub, a shaft hole, and trapezoidal blades with teeth, wherein the shaft hole is formed in the center of the hub; the trapezoidal blades with teeth are uniformly distributed on the outer side of the hub. The trapezoidal blade stirring paddle is simple in structure and has a good stirring function and a strong bubble breaking function, so that the gas is well mixed with a culture medium, the medium exchange contact surface is enlarged, and oxygen is fully utilized.
Description
Technical field
What the present invention relates to is a kind of stirrer paddle, is specifically related to the toothed trapezoidal leaf paddle of a kind of periphery.
Background technology
Normally used on fermentation tank is at present the paddle of the shapes such as square straight leaf, curved leaf.Also develop many novel paddles.Increase for increase gas-liquid mass transfer etc.But often relatively heavy, have due to by reasons such as material are thinner, cause using after one-phase, stirrer paddle deforms.Destroy the Equilibrium of paddle.Increase the vibrations of stirring system.Affect the service life of shaft and associated components.
Summary of the invention
For the deficiency existing in prior art, the present invention seeks to be to provide a kind of periphery toothed trapezoidal leaf paddle, simple in structure, there is better agitating function and stronger broken bubble function, thereby make gas better mix with culture medium and increase Medium Exchange contact-making surface, make the utilization of oxygen more abundant.
To achieve these goals, the present invention realizes by the following technical solutions: the toothed trapezoidal leaf paddle of a kind of periphery, the paddle of the described trapezoidal leaf of peripheral band tooth comprises wheel hub, axis hole, toothed trapezoid blade, axis hole is arranged on wheel hub center, and wheel hub outside is evenly distributed with the toothed trapezoid blade of periphery.
As preferably, the paddle of the described trapezoidal leaf of peripheral band tooth comprises wheel hub, axis hole, toothed trapezoid blade and disk, and axis hole is arranged on wheel hub center, and wheel hub is connected and center superposition with disk, is evenly distributed with the toothed trapezoid blade of periphery on disk.
As preferably, four jiaos of toothed trapezoid blades of described periphery can be to occur with forms such as rudimentary horn, chamfering, arc chord angles; Stirring power transmission shaft top is connected with stirring driving motor through stirring tank body.Stir the paddle that the trapezoidal leaf of peripheral band tooth is housed on power transmission shaft.
The present invention is simple in structure, has better agitating function and stronger broken bubble function, thereby makes gas better mix with culture medium and increase Medium Exchange contact-making surface, makes the utilization of oxygen more abundant.

Detailed description of the invention
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with nonrestrictive detailed description of the invention, further set forth the present invention.
With reference to Fig. 1-7 detailed description of the invention by the following technical solutions: the toothed trapezoidal leaf paddle of a kind of periphery, the paddle of the described trapezoidal leaf of peripheral band tooth comprises wheel hub, axis hole, toothed trapezoid blade, axis hole is arranged on wheel hub center, and wheel hub outside is evenly distributed with the toothed trapezoid blade of periphery.
This detailed description of the invention, in the time that agitator rotates, approaches the suffered moment of torsion of paddle root (paraxial place or near leaf Pan Chu) larger, more approaches the suffered moment of torsion in the blade face of marginal portion less.Trapezoidal, under same active force, root blade face is wider, more difficult distortion.Because it has intensity booster action, under equal stirring condition, the thickness of blade is attenuate suitably, thereby entirety reduces the weight of agitator.Reduce the load of stirring motor.Save the energy.
The toothed trapezoid blade of periphery of this detailed description of the invention, the possibility of minimizing deformable blade, reduces the unbalanced probability in paddle use procedure, has extended the service life of paddle.More meet mechanics principle.More meet the user demand of aerobic fementation occasion.Trapezoidal paddle, stirring vane edge bottom generally also more more agrees with the bottom shape of tank body.(common fermentation tank bottom is arc or taper) more easily stirs the material of bottom at the bottom of tank, also more easily touches the air coming from lower square tube.Can more early air bubble must be smashed sooner.Dispersion preferably and bubble disintegration, be conducive to the transmission of oxygen.Improve the gas-liquid dispersion ability that (especially bottom) stirs.Be suitable for the fermented liquid that viscosity is higher.
Paddle periphery contains dentalation, in the time that paddle rotates, can suitably strengthen on the one hand axial flow flows, make gas in fermentation tank, stop the more time, also be the novel part of technology on the other hand, he can have the broken bubble function stronger than general paddle, thereby makes gas better mix with culture medium and increase Medium Exchange contact-making surface, further makes the utilization of oxygen more abundant.
This detailed description of the invention be more prone to make bubble breaking with the trapezoidal paddle of tooth than common anodontia paddle, the surface area of (tooth-like structure is more easily destroyed bubble surface and opened equilibrium of forces) so overall bubble will increase relatively, thereby increase the contact-making surface of gas-liquid, be conducive to gas-liquid mass transferring process.Also be more suitable for the gas-liquid mass transfer in zymotic fluid that viscosity is higher.Can say the consumption of having saved air from another angle.Accomplish energy-conservation.
Embodiment: the toothed trapezoidal leaf paddle of a kind of periphery of the present embodiment, comprise the trapezoidal leaf disc formula of four leaf band teeth agitator 1, the trapezoidal leaf open type of four leaf band teeth agitator 2, the trapezoidal leaf disc formula of six leaf band teeth agitator 3, stir power transmission shaft 4 and stir driving motor 5, the trapezoidal leaf disc formula of four leaf band teeth agitator 1, the trapezoidal leaf open type of four leaf band teeth agitator 2, the trapezoidal leaf disc formula of six leaf band teeth agitator 3 are arranged on and stir on power transmission shaft 4, stir power transmission shaft 4 tops and are connected with stirring driving motor 5 through stirring tank body; The described trapezoidal leaf disc formula of four leaf band teeth agitator 1 comprises the first axis hole 11, first wheel 12, the first band tooth trapezoid blade 13 and the first disk 14, the first disk 14 centers are provided with the first axis hole 11, the first axis hole 11 is outside equipped with and on first wheel 12, the first disks 14, is evenly provided with four first band tooth trapezoid blades 13.
