Description
Technical field
The utility model relates to a kind of agitator arm, and especially a kind of dual channel revolves suction and is uniformly mixed turbine.
Background technology
At present at sewage treatment area, activated sludge biochemical facture is that one will main technology mode, especially in municipal administration and large-scale trade effluent engineering of water treatment, biochemical treatment section is the core content of whole technique, usually the process seen has AO method, AAO method, SBR method etc., the reactive mode of biochemical section mainly comprises the states such as anaerobic/anoxic, under anaerobic/anoxic state, mixer is a kind of conventional key equipment, the homogeneous of solid-liquid two-phase flow and solid-liquid-gas three phase stream in biochemical process can be realized, the technological requirement of flowing, play in technical process and prevent the activated sludge suspended from precipitating, increase its mixture homogeneity, to improve the effect of biochemical reaction efficiency.Especially in recent years, along with building in a large number of domestic sewage treatment plant, simultaneously to the requirement increasing dephosphorization in sewage treatment process and denitrogenate index, in technique, anaerobic/anoxic ratio increases, and has proposed higher requirement to the high reliability of sewage disposal device therefor and long-life.Adopt land motor to coordinate the agitating mode of vertical shaft type multiaspect moulding impeller, with its good reliability, efficiency is high, more and more comes into one's own in engineer applied.But also come with some shortcomings in Practical Project, such as application number be 201220332811.8 Chinese patent disclose a kind of Double-curved-surface stirring machine, because curved blade impeller is monoblock type, when impeller diameter is larger, will inevitably produce in wheel bottom and stir dead angle, therefore must consider fluidized―bed furnace problem.
Utility model content
The purpose of this utility model is: for above-mentioned prior art Problems existing, proposes a kind of can elimination and is uniformly mixed the dual channel that turbine inner bottom part produces precipitation and revolves suction and be uniformly mixed turbine.
In order to reach above object, dual channel of the present utility model revolves suction and is uniformly mixed turbine, comprise the paddle wheel body be connected with pto, the outer surface of impeller body is that hyperbola bus rotates the hyperboloid formed around foreign steamer body axis, guide vane group is radially distributed with at the outer surface of impeller body, guide vane group comprises cross-coupled first flow deflector and the second flow deflector, water conservancy diversion through hole is provided with at the first flow deflector and the second flow deflector infall, water conservancy diversion through hole is communicated with outer surface and the inner surface of impeller body, due to be uniformly mixed turbine rotate under water time, surface of revolution surfaces externally and internally can be made to produce pressure differential, therefore by arranging that the formation of water conservancy diversion through hole rotates and being parallel to axial bumpy flow, effectively can eliminate the precipitation being uniformly mixed turbine inner bottom part and producing, improve axial velocity and the water flux density of current simultaneously, thus enhancing mixed effect.
Preferred version of the present utility model is:
Further, the hyp equation of impeller body is xy=b.
Further, in same group of guide vane group, the rotating flow guidance direction of the first flow deflector and the second flow deflector is contrary.
Further, guide vane group is 8 groups.
Further, adjacent two panels first flow deflector crosses connected near the one end at impeller body center each other, and adjacent two panels second flow deflector crosses connected near the one end at impeller body edge each other.
Further, the global shape of the first flow deflector and the second flow deflector is wedge shape or aerofoil profile.
The utility model beneficial effect is: by arrange water conservancy diversion through hole formed eight rotate and be parallel to axial bumpy flow, effectively can eliminate the precipitation being uniformly mixed turbine inner bottom part and producing, improve axial velocity and the water flux density of current simultaneously, thus strengthen mixed effect.

Detailed description of the invention
Embodiment one
The dual channel that the present embodiment provides revolves suction and is uniformly mixed turbine, as shown in Figure 2, the middle part of paddle wheel body is provided with the flange 1 connecting power output shaft, the hyperboloid of the outer surface of impeller body to be hyperbola bus equation be xy=b, 8 groups of guide vane groups are radially distributed with at the outer surface of impeller body, guide vane group comprises cross-coupled first flow deflector 2 and the second flow deflector 3, water conservancy diversion through hole 4 is provided with at the first flow deflector 2 and the second flow deflector 3 infall, water conservancy diversion through hole 4 is communicated with outer surface and the inner surface of impeller body, in same group of guide vane group, the rotating flow guidance direction of the first flow deflector 2 and the second flow deflector 3 is contrary, adjacent two panels first flow deflector 2 crosses connected near one end of impeller body center flange 1 each other, adjacent two panels second flow deflector 3 crosses connected near the one end at impeller body edge each other,
The water conservancy diversion effect of real work as shown in Figure 1, because surface of revolution surfaces externally and internally has pressure differential, therefore by arrange water conservancy diversion through hole 4 formed eight groups rotate and be parallel to axial bumpy flow, effectively can eliminate the precipitation being uniformly mixed turbine inner bottom part and producing, improve axial velocity and the water flux density of current simultaneously, thus strengthen mixed effect.
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 on the protection domain of the utility model requirement.
