Abstract
The utility model discloses a diversion - type agitator for height glues fermentation system, including wheel hub (1) and equipartition at wheel hub (1) on every side and rather than paddle (2) of location connection, the diversion - type agitator is installed on central (mixing) shaft (5), arranged on paddle (2) water conservancy diversion spare (3), water conservancy diversion spare (3) are for lining up the structure, the projection line of its central line on the work surface of revolution is 15-75 with paddle (2) the extension line contained angle that stirs the axle center excessively, can change the fluid medium who passes through transmission direction makes fluid medium flow direction center, thereby improve the mass transfer and mix the effect.
Description
Technical field
The utility model relates to chemical industry and stirs fermentation system is glued in field agitator for height, comprises 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 problems to be solved in the utility model improves the mass transfer mixed effect of stirred tank inner fluid medium in whipping process by improving agitator structure.
The technical scheme that the utility model technical solution problem 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.While this flow guiding type agitator can also be arranged in central stirring shaft, central stirring shaft is not limited only to this flow guiding type agitator is installed.
The beneficial effects of the utility model be design flow guiding type agitator by its with conducting element guide functions, greatly can improve mass transfer and the mixed effect of stirred tank inner fluid medium.

Fig. 2 is flow guiding type agitator front view.
Fig. 3 is the top view of the agitator of flow guiding type shown in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, following explanation is done to a kind of embodiment of the present utility model.
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 utility model, 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.
Claims (5)
