By adopting the technical scheme, the multistage countercurrent stirring paddle has the advantages of simple structure, low manufacturing cost, good stirring effect and wide use range, can be widely used in medium and small stirring tanks, and has good economic and social benefits.
Description
Technical field:
The present invention relates to agitating device, especially a kind of multistage counter current paddle.
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 manufacturing cost is high, generally is used for large-scale tank diameter, and when in middle-size and small-size tank diameter, using, overall cost performance is very low.
Summary of the invention:
Goal of the invention: a kind of multistage counter current paddle is provided, and it is high effectively to solve existing paddle manufacturing cost, and the problem that can not in middle-size and small-size tank diameter, promote the use of.
In order to reach as above purpose, the present invention takes following technical scheme: comprise shaft and blade, said blade comprises the interior blade sheet and relative outer blade sheet away from shaft near shaft.
The further technical scheme of the present invention is: the blade sheet is connected through flanged connection system with outer blade sheet in said.
The further technical scheme of the present invention is: oar flange and outer oar flange in said flanged connection system comprises connect through nuts and bolt between the two.
The further technical scheme of the present invention is: the blade sheet is different with the angle of shaft center line with outer blade sheet in said.
The further technical scheme of the present invention is: the blade sheet is 45 °～60 ° near the root of shaft and the angle of shaft center line in said.
The further technical scheme of the present invention is: the blade sheet is 70 °～80 ° away from the end of shaft and the angle of shaft center line in said.
The further technical scheme of the present invention is: the angle of said outer blade sheet and shaft center line is 55 °～65 °.
The further technical scheme of the present invention is: on the said shaft journal stirrup is housed, interior blade sheet is connected fixing with shaft through the journal stirrup that is welded on the shaft with bolt and nut.
Adopt as above the present invention of technical scheme, have following beneficial effect: simple in structure, low cost of manufacture, mixing effect is good, and the scope of application is extensive, can in middle-size and small-size tank diameter, be widely used, and has good economic and social benefit.
Description of drawings:
In order to further specify the present invention, further describe below in conjunction with accompanying drawing:
Fig. 1 is a structural front view of the present invention;
Fig. 2 is a vertical view of the present invention;
Fig. 3 is a left view of the present invention;
Wherein: 1. outer blade sheet; 2. outer oar flange; 3. nut; 4. bolt; 5. interior oar flange; 6. interior blade sheet; 7. shaft; 8. journal stirrup; 9. bolt and nut.
The specific embodiment:
Below in conjunction with accompanying drawing embodiments of the invention are described, embodiment is not construed as limiting the invention:
Shown in Fig. 1-3; The present invention includes shaft and blade, the blade symmetry is contained on the shaft, and blade is made up 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, and 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 is formed outer blade with inner outer oar flange 2; Inside and outside blade links together through inside and outside oar flange, and the angle of interior blade sheet root (the inner) and shaft center line is that 45 °～60 °, interior blade sheet end of blade (outer end) are 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 with bolt 4 by nut 3 and fix.
On the said shaft 7 journal stirrup 8 is housed, interior blade is connected fixing with shaft through the journal stirrup that is welded on the shaft with bolt and nut 9.
Blade sheet 6 is to utilize twist machine to reverse certain angle to elongated steel sheet to form in said; Promptly; The angle of blade sheet root (the inner) and shaft center line is that the angle of 45 °～60 °, interior blade sheet end of blade and shaft center line is 70 °～80 ° in making, and the angle of outer blade sheet and shaft is 55 °～65 °.
The further technical scheme of the present invention is: blade sheet 6 is different with the angle of shaft center line with outer blade sheet 1 in said.Can conveniently realize the mixing effects that need more.
Working condition of the present invention is, the running of driven by motor reductor, and reductor drives shaft and rotates, and shaft drives the blade motion, through curved surface, the inclined plane shape of interior blade sheet 6 and outer blade sheet 1, the realization multistage counter current, thus material is stirred.
When using, the present invention adopts the multilayer arrangement; Through curved surface, the inclined plane shape of interior blade and outer blade, thereby realize multistage counter current, practiced thrift 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.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; The present invention also has various changes and modifications under the prerequisite that does not break away from spirit and scope of the invention, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
