Abstract
The invention discloses a flow-guide-type stirrer for a high-viscosity fermentation system. The flow-guide-type stirrer comprises a hub (1) and paddles (2), wherein the paddles (2) are uniformly distributed around the hub (1) and connected with the hub (1) in a positioned manner, a flow-guide-type stirrer body is mounted on a central stirring shaft (5), flow guide parts (3) are distributed on the paddles (2) and adopt a through structure, the included angle between a projection line, on a rotary work surface, of the central line of each flow guide part (3) and an extension line, passing through the axis of the stirring shaft, of the corresponding paddle (2) ranges from 15 degrees to 75 degrees, the conveying direction of a fluid medium passing through the flow-guide-type stirrer can be changed, so that the fluid medium can flow towards the central position, and the medium conveying and mixing effects can be improved.
Description
Technical field
The present invention relates to chemical industry and stir fermentation system is glued in field agitator for height, comprise wheel hub and blade.
Background technology
For the product of biofermentation, as xanthans, gellan gum etc., viscosity can increase gradually during the fermentation, and particularly very high in middle and later periods viscosity, its fermentation liquid is typical pseudoplastic fluid, has the character of shear thinning.For shear-thinning fluid, in whipping process agitator blade tips near form high-shear region, form relatively low viscosity region.In the propeller shank central area near agitator, the lower thus viscosity of shearing rate is relatively high.In stirred tank, this non-newtonian flow knows from experience formation viscosity gradient, mixes soon in propeller-blade terminal fluid flowing velocity, and poor at the slow mixed effect of propeller-blade root central area fluid-flow rate.When passing into gas and mixing with fluid media (medium), appear at propeller-blade end regions good mixing effect, and the fluid media (medium) viscosity high fluidity difference near propeller-blade root central area is difficult to participate in the mixing of overall evenly mass transfer by circulation, this phenomenon can reduce the performance of reactor widely.How to improve agitator structure to improve the mass transfer mixed effect of stirred tank inner fluid medium in whipping process, become the difficult problem needing in the industry to consider.In usual stirred tank, shaft has installed multilayer agitator, every layer of agitator comprises wheel hub and blade, and according to design needs, blade has various ways.
Summary of the invention
The technical problem to be solved in the present invention improves the mass transfer mixed effect of stirred tank inner fluid medium in whipping process by improving agitator structure.
The technical scheme that technical solution problem of the present invention is taked is a kind of flow guiding type agitator gluing fermentation system for height of design, comprise wheel hub and be distributed on the blade be located by connecting around wheel hub and with it, flow guiding type agitator is arranged in central stirring shaft, blade to be arranged several conducting elements, conducting element is communicating structure, can make tubular type, square or triangle, its center line is at the projection line worked on the surfaces of revolution and cross the blade extended line angle stirring axle center
it is 15 ° ~ 75 °.During work, shaft rotarily drives flow guiding type agitator and rotates thereupon, conducting element on blade makes the elicitation effect power being subject to conducting element inwall by the fluid media (medium) in its through path flow to propeller shank central area, central area fluid compression is gone out to the blade tips near zone of peripheral agitator simultaneously, central area and outer peripheral areas in stirred tank can be kept like this to be in good mass transfer admixture all the time.This flow guiding type agitator can be that then specialized designs is arranged in central stirring shaft, original other types agitator in stirred tank is coordinated to work together, also can be by forming the other types agitator transformation of the way original in stirred tank, namely in stirred tank original other types agitator blade on change a social system with conducting element, make original other types agitator in stirred tank become flow guiding type agitator.
The invention has the beneficial effects as follows the flow guiding type agitator of design by its with conducting element guide functions, greatly can improve mass transfer and the mixed effect of stirred tank inner fluid medium.

Detailed description of the invention
Below in conjunction with accompanying drawing, following explanation is done to one embodiment of the present invention.
In Fig. 1 prior art, shaft (5) enters in still by the still mouth of stirred tank (6), (5) are provided with agitator to shaft, agitator comprises wheel hub (1) and blade (2), fill fluid media (medium) in still during work, agitator is by blade (2) stirred fluid media implementation mass transfer and mixing.
Fig. 2 is a kind of flow guiding type agitator gluing fermentation system for height of the present invention, comprise wheel hub (1) and be welded on upper symmetrical a pair blade (2) of wheel hub (1), a pair blade (2) first processes perforate, then the conducting element (3) of tubular type structure is welded on position of opening, and makes the projection of conducting element (3) center line on the work surfaces of revolution and cross blade (2) the extended line angle stirring axle center
be 45 °, Fig. 3 have expressed angle
schematic diagram, flow guiding type agitator coordinates the screw (4) on wheel hub (1) to install by holding screw to be positioned on shaft.
