Description
Technical field
The present invention relates to a kind of turbine, more particularly to a kind of vertical mixer high-efficiency stirring turbine.
Background technology
In the Activated Sludge Process of sewage disposal, the sewage in biological tank will ceaselessly be stirred by mixer, with
Sludge settling is prevented, promotes beneficial microbe growth and breeding in activated sludge, the purpose of the dirty Organic substance in water of separation is reached.For
The mixer of stirring sewage mainly has diving mixer and vertical Double-curved-surface stirring machine etc..Because vertical Double-curved-surface stirring machine is than latent
Water mixer is more saved, and motor, the reductor installed on the water are easy to maintenance, therefore are stirred in recent years in biological tank sewage
Mix and obtained increasingly being widely applied in technique.However, Double-curved-surface stirring machine exists necessarily not in Practical Project operation
Foot, the Chinese patent of such as Application No. 201220332811.8 discloses a kind of Double-curved-surface stirring machine, due to mixer hyperbolic
Surface impeller is that the sewage being disposed with the latter half of impeller body upper surface in blade, pond has stirring non-uniform phenomenon,
There is bottom of pond below flow velocity very low slough, impeller above impeller has sludge settling, simultaneously as the height of blade is low, leaf
The region of piece stirring is narrower, when sewage solid content and viscosity rising, and when mobility is deteriorated, stirring efficiency declines, and mixing effect becomes
Difference, if increasing stirring intensity simply by wheel speed is improved, will cause mixer power consumption to increase considerably.In view of above-mentioned lack
Fall into, be necessary to design a kind of vertical mixer high-efficiency stirring turbine in fact.
