A kind of Multi-impeller stirring system
Technical field
The utility model relates to a kind of Multi-impeller stirring system of fast and stable.
Background technology
Instantly, in the middle of real life and work, there is the material demand of a lot of liquid state or paste through stirring, use needed performance to reach.The shaft that stirring system drives one end to be provided with impeller by power facility forms, due to the physical condition of liquid in the direction stirring and whipping process, can form a whirlpool along shaft, both the uniformity and the mixing quality of stirring had been affected, easily be involved in again air, also can, because of the powerful centrifugal force of impeller end, affect the service life of shaft.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of Multi-impeller stirring system, and this Multi-impeller stirring system is stable, and mixing quality and speed obviously improve and can not be involved in air.
The utility model is achieved by the following technical solution:
A kind of Multi-impeller stirring system, it is characterized in that, comprise shaft and the identical impeller of more than two blade quantity, vertical and the interval of impeller is fixedly installed on shaft, the projection of the blade of adjacent two impellers on the face vertical with shaft is not overlapping, and on perspective plane, the angle of adjacent two blades is 30-65 degree.
Further, each impeller forms by 3 blades.
Further, on perspective plane, the angle of adjacent two blades is 60 degree.
The stress direction difference that while stirring due to Multi-impeller stirring system, adjacent two impellers form, just in time form complementary relation, in whipping process, whole system can be in a kind of stable state, the suffered centrifugal force of shaft reduces greatly, to significantly improve its service life, owing to there being the mixing power of different directions, the quality of stirring and speed also can improve, and do not have the hidden danger that is involved in air simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is illustrated.As depicted in figs. 1 and 2, a kind of Multi-impeller stirring system of the utility model comprises shaft 2 and the impeller 1 that more than two blade quantity is identical, vertical and the interval of impeller 1 is fixedly installed on shaft 2, the projection of the blade of adjacent two impellers 1 on the face vertical with shaft 2 is not overlapping, and the angle of adjacent two blades is 30-65 degree on perspective plane, preferably 60 degree.
As shown in Figure 3, existing shaft liquid in the time stirring moves along direction shown in arrow, and forms a whirlpool at A point, and while not only stirring, centrifugal force is large, and can be involved in air.The utility model shaft 2 is provided with multiple impellers 1, and there is misalignment angle between adjacent two impellers 1, so, the stress direction difference that adjacent two impellers 1 form in the time stirring, just in time forms complementary relation, in whipping process, whole system can be in a kind of stable state, the suffered centrifugal force of shaft 2 reduces greatly, and significantly improve its service life, simultaneously owing to there being the mixing power of different directions, the quality and the speed that stir also can improve, and do not have the hidden danger that is involved in air.
