Description

A kind of curved surface Agitator Impeller for liquid agitation
Technical field
The utility model relates to a kind of curved surface Agitator Impeller for liquid agitation, belongs to field of hydraulic machinery.
Background technology
In the fields such as chemical industry, the energy, environmental protection especially sewage treatment process, curved surface mixer can be used, commonly in the occasions such as coagulating basin, regulating reservoir, sludge-tank, anaerobic pond, use curved surface mixer to carry out stirring at low speed.Curved surface mixer is generally made up of motor, reductor, power transmission shaft, impeller.During work, impeller stretches into fluid object, under the drive of motor and speed reducer, stirs fluid.Curved surface Agitator Impeller adopts glass steel material usually, and formed by shaping the solidifying of large mold, this kind of impeller intensity is less compared to steel, collision cracky, and junction is insecure.
Utility model content
The purpose of this utility model is: for the problems referred to above, provides a kind of curved surface Agitator Impeller for liquid agitation, adopts Steel material to make, improves the strength and stability degree of impeller.
In order to reach above object, the technical solution of the utility model is as follows:
For a curved surface Agitator Impeller for liquid agitation, comprise mandrel, impeller boss, impeller curved surface, guide vane, it is characterized in that: the upper and lower two ends of described mandrel are provided with concentric upper flange and lower flange, described upper flange place is provided with impeller boss; Described impeller curved surface is skirt revolving body, and the lower edge of its minor diameter openend and described impeller boss is connected; Described impeller curved surface is formed by several thin plate splicings, and described thin plate being projected as in the plane vertical with mandrel is trapezoidal, and described thin plate is uniform along impeller boss circumference, is connected bottom it with steel ring; The inner surface of described impeller curved surface be fixed with several ringwise in hold round, hold round with one heart in each; The outer surface of described impeller curved surface is provided with the guide vane of several Rotational Symmetry distributions centered by the axis of impeller curved surface.
The upper and lower two ends of mandrel are equipped with flange, and be convenient to mandrel upper end and be connected with power transmission shaft, lower end is connected with back shaft.Impeller curved interior surface be fixed with some in hold round, this interior holding round can be reinforced further to impeller curved surface.Impeller curved surface is skirt revolution build, and curved outer surface is provided with some arc guide vanes, when wheel rotation, the rotary motion of guide vane propelling fluid, fluid replacement enters from impeller central, through the flowing of impeller curved surface, to the pressure uniform of impeller surface, ensure that curved surface mixer is stable.Adopt this structure, water flow stationary, stir scope large.
Preferably, described impeller boss is circular platform type.
Preferably, the lower flange place of described mandrel, is fixed with the back shaft to downward-extension.Back shaft can be supported at the bottom of pond, strengthens the stability that curved surface mixer runs further.
Preferably, described guide vane is 6 ~ 8.
Preferably, the diameter of described impeller is 500 ~ 3000mm.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is the structural representation of a kind of curved surface Agitator Impeller for liquid agitation of the utility model;
Fig. 2 is the top view of Fig. 1 embodiment one impeller;
Fig. 3 is the schematic appearance of embodiment one.
Detailed description of the invention
In order to understand the utility model better, below in conjunction with accompanying drawing, a kind of detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, a kind of curved surface Agitator Impeller for liquid agitation, comprises mandrel 1, impeller boss 2, impeller curved surface 3, guide vane 4 etc. to the first embodiment of the present utility model.Mandrel about 1 two ends are provided with concentric upper flange 5 and lower flange 6.Upper flange 5 place is provided with the impeller boss 2 in circular platform type, and impeller boss 2 is connected with the upper flange 5 of mandrel 1.Impeller curved surface 3 is skirt revolving body, and the lower edge of its minor diameter openend and impeller boss 2 is connected.As shown in Fig. 2, the outer surface of impeller curved surface 3 is provided with the arc guide vane 4 of eight Rotational Symmetry distributions centered by the axis of impeller curved surface 3.Impeller curved surface 3 is spliced by 32 identical thin plates 7, and thin plate 7 is uniform along impeller boss 2 circumference, is connected bottom it with steel ring 9.Thin plate 7 being projected as in the plane vertical with mandrel 1 is trapezoidal.As shown in Figure 1, the inner surface place of impeller curved surface 3 be fixed with three ringwise in hold round 8, hold round 8 in each and to be parallel to each other and with one heart.Inside hold round 8 can reinforce impeller curved surface further.
When wheel rotation, the rotary motion of guide vane propelling fluid, fluid replacement enters from impeller central, through the flowing of impeller curved surface, to the pressure uniform of impeller surface, ensures that curved surface mixer is stable.Adopt this structure, water flow stationary, stir scope large.
Lower flange 6 place of mandrel 1, can also be fixed with the back shaft to downward-extension, and during use, back shaft can be supported at the bottom of pond, strengthens the stability of curved surface mixer work further.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
