Abstract
The utility model relates to a multi-section counter-flow stirring paddle which effectively solves the problems that the prior stirring paddle has high manufacturing cost and cannot be promoted and used in medium-sized and small-sized stirring troughs; the stirring paddle comprises a stirring shaft and blades; the blades are symmetrically arranged on the stirring shaft, and comprise an inner blade and an outer blade; the inner end of an inner vane is arranged on the stirring shaft, and an inner flange is welded on the outer end; an outer flange is welded on the inner end of an outer vane; the inner vane and the inner flange on the outer end form the inner blade; the outer vane and the outer flange on the inner end form the outer blade; the inner blade and the outer blade are connected together by the inner and the outer flanges; the angle between the root of the inner vane and the center line of the stirring shaft is 45 degrees to 60 degrees, the angle between the end of the inner vane and the center line of the stirring shaft is 70 degrees to 80 degrees, and the angle between the outer vane and the stirring shaft is 55 degrees to 65 degrees. The multi-section counter-flow stirring paddle can be widely applied in medium-sized and small-sized stirring troughs, and has good economic and social benefit.
Description
One, technical field
The utility model relates to agitating device, particularly a kind of multistage counter current paddle.
Two, background technology
The alumina industry use at home and abroad of MIG or IMIG oar is very extensive, and the MIG meaning is the multistage counter current agitator.The design principle of this impeller is that when impeller rotated, the end and the root of blade advanced liquid respectively in the opposite direction, promoted liquid to form axial circulation.It is particularly suitable for the transition basin work of finishing drilling.In the transition basin, there is little vortex near the impeller, in the occasion of using multi-layer impeller, the turbulent area of adjacent impeller can couple together, form the whole axial circulation of complete jar inner fluid, so have and the suitable mixing rate of inside and outside ribbon impeller, the power levels of these two kinds of impellers is counted N on the other hand
PLess than inside and outside single ribbon impeller.During it is very suitable for, the solid-liquid suspension of end viscosity liquid, liquid-liquid disperses and conduct heat.This kind blade use at present is very general, but the manufacturing cost height generally is used for large-scale tank diameter, and when using in middle-size and small-size tank diameter, overall cost performance is very low.
Three, utility model content
At above-mentioned situation, for overcoming the defective of prior art, the purpose of this utility model just provides a kind of multistage counter current paddle, can effectively solve existing paddle manufacturing cost height, and the problem that can not in middle-size and small-size tank diameter, promote the use of, the technical scheme of its solution is, comprise shaft and blade, the blade symmetry is contained on the shaft, blade is made of interior blade and outer blade, interior blade sheet the inner is contained on the shaft, the outer end is welded with interior oar flange, outer blade sheet the inner is welded with outer oar flange, blade in the interior oar flange of interior blade sheet and outer end is formed, outer blade sheet and inner outer oar flange are formed outer blade, and inside and outside blade links together by inside and outside oar flange, interior blade sheet root (the inner) is 45 °～60 ° with the angle of shaft center line, the angle of interior blade sheet end of blade and shaft center line is 70 °～80 °, and the angle of outer blade sheet and shaft is 55 °～65 °.
The utility model is simple in structure, low cost of manufacture, and mixing effect is good, and the scope of application is extensive, can be extensive use of in middle-size and small-size tank diameter, has good economic and social benefit.
Four, description of drawings
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is a left view of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing detailed explanation is done in concrete enforcement of the present utility model.
Provide by Fig. 1-3, the utility model comprises shaft and blade, the blade symmetry is contained on the shaft, blade is made of interior blade and outer blade, interior blade sheet 6 the inners are contained on the shaft 7, the outer end is welded with interior oar flange 5, outer blade sheet 1 the inner is welded with outer oar flange 2, blade in the interior oar flange 5 of interior blade sheet 6 and outer end is formed, outer blade sheet 1 and inner outer oar flange 2 are formed outer blade, inside and outside blade links together by inside and outside oar flange, interior blade sheet root (the inner) is 45 °～60 ° with the angle of shaft center line, interior blade sheet end of blade (outer end) is 70 °～80 ° with the angle of shaft center line, and the angle of outer blade sheet and shaft is 55 °～65 °.
For safeguard and use easy to assembly, said in oar flange 5 and outer oar flange 2 be connected and fixed by nut 3 and bolt 4.
On the said shaft 7 journal stirrup 8 is housed, interior blade and shaft are connected and fixed with bolt and nut 9 by the journal stirrup that is welded on the shaft.
Working condition of the present utility model is, the running of driven by motor reductor, and reductor drives shaft and rotates, and shaft drives the blade motion, by curved surface, the inclined plane shape of interior blade and outer blade, the realization multistage counter current, thus material is stirred.
When using, adopts the utility model the multilayer arrangement, by curved surface, the inclined plane shape of interior blade and outer blade, thereby realize multistage counter current, saved the use cost of MIG oar in middle-size and small-size mixing plant greatly, and reaching desirable mixing effect, the scope of application is also more extensive simultaneously.
