Technique effect of the present utility model is:
The utility model water treatment with vertical stirring impeller because its revolution curve that constitutes surface of revolution is one section Archimedes spiral of reducing successively of curvature from top to bottom, the variation of this curve curvature radius current flow velocity variation from slow to fast from axially transfer radially process to that coincide, reduced resistance to water-flow, make the downward current of following current can the impeller edge assemble to form rapidly to around the impact current that arrange, it is stronger to be equivalent under identical rotary power whipping power, therefore further improved the stirring fluidised form, and low in energy consumption, fault rate is low.
The water conservancy diversion rib is set further prays the plug-flow effect, when the mashing beam wheel body turns round in water body, the water of pond bottom under the plug-flow effect of water conservancy diversion rib rapidly to around arrange, after arriving pool wall, rise along pool wall by the pool wall blocking effect, cover to the eddy current center by water level potential energy, it is impeller body top, flow to the impeller body at last again, thereby the water body in the pond is formed: lower curtate from inside to outside, periphery from bottom to top, top from outside to inside, center axial circulation and the whole water body eddy current fluidised form of making circular motion around the axle center from top to bottom, reach solid, liquid, the abundant stirring of gas three-phase flow or two-phase flow with mix, eliminated the defective that stirs the dead angle.
The hollow and thin-walled structure of the described impeller body of utility model has not only alleviated the weight of impeller body self, and when rotation, because the vacancy produces negative pressure in the impeller below, this place negative pressure can make the impeller body keep centralized positioning, automatic deviation correction, and prevention impeller body rocks.Circular and smooth wheel rim can prevent to be twined by fibre object.The surface of revolution surface is not twined by foreign material such as fibre object owing to this impeller, and is in light weight.
The described stirring impeller of utility model adopts the nonmetallic materials manufacturing, and arc water conservancy diversion rib and impeller surface of revolution cast solid are in light weight, corrosion-resistant.
Description of drawings
Fig. 1 is the structural representation of the utility model water treatment with the stirring impeller;
Fig. 2 uses for the utility model water treatment and stirs impeller camber line schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail.
Embodiment 1
Water treatment among Fig. 1 is with vertical stirring impeller, comprise that its stirring face 2 encloses 21 around stirring the umbrella shape mashing beam wheel body 1 that the axis rotation constitutes surface of revolution for the revolution curve, revolution curve 21 is one section Archimedes spiral (see figure 2), and on this impeller body 1 axis direction, the big line end of this section helical curvature is last, the line end that curvature is little is descending, and promptly surface of revolution 2 (promptly stirring face 2) is the surface of revolution that one section Archimedes spiral forms around the rotation of impeller body 1 axis.Preferably, described Archimedes spiral polar equation is ρ=α θ (α=υ/ω).The variation of this curve curvature radius has coincide current from axially transferring radially the flow velocity variation from slow to fast the rotary movement along the circumferential direction of process and current to, therefore current are rolled smoothly up and down, stirred uniformly, avoided the dead angle, and minimizing flows to the resistance to water-flow of impeller below from the impeller top, make pool inner water downwards and to around flow more unimpeded, and then minimizing energy consumption, the whole potential energy that forms when outwards throwing is bigger simultaneously, impact after arriving pool wall is also bigger, therefore stirs more abundant.
At mashing beam wheel body 1 stirring face 2 the arc water conservancy diversion rib 3 of many projectioies is arranged, arc water conservancy diversion rib 3 radially is evenly distributed.Distance between the arc refluence rib 3 preferably equates.Preferably, arc water conservancy diversion rib 3 starting altitude h1 originate in impeller body 1 outer rim 4, end at the 1/3-1/2 place of impeller body 1 height h2, and arc water conservancy diversion rib 3 up extends De Taigao on impeller body 1 surface of revolution, be unfavorable for that on the contrary taking advantage of a situation of current is dirty, increases energy consumption.Arc water conservancy diversion rib 3 height successively decreases to center position from mashing beam wheel body 1 edge 4.Arc water conservancy diversion rib 3 cross section a are right angled triangle, and the turning of right angled triangle is an arc transition.Cambered surface b perpendicular to the arc refluence rib 3 of impeller body 1 surface of revolution 2 is a upstream face, can effectively promote water movement.Certainly, the shape of cross section a also can be other polygons, can adjust according to different reactive fluids and power.
Preferably, the wheel rim 4 of mashing beam wheel body 1 (being outer rim 4, also is edge 4) is circular and smooth wheel rim 4, can prevent that fibre object is wrapped on the impeller body.The surface of revolution surface is not twined by foreign material such as fibre object owing to this impeller, and is in light weight.
Mashing beam wheel body 1 is the hollow and thin-walled part, and adopts the nonmetallic materials manufacturing.Preferably, arc water conservancy diversion rib 3 and impeller body 1 surface of revolution cast solid.The hollow and thin-walled structure has not only alleviated the weight of impeller body 1 self, and during rotation, because the vacancy produces negative pressure in impeller body 1 below, this place negative pressure can make impeller body 1 keep centralized positioning, automatic deviation correction, and prevention impeller body rocks.Described impeller body 1 adopts fiberglass with water conservancy diversion rib 3, and cast solid, and this material weight is light, and is corrosion-resistant, improves its service life.This impeller body 1 also can adopt fibre reinforced plastics or other light material to make.
This stirring impeller is particularly useful for the stirring technique in the water treatment technology, stirs and mixes as regulating reservoir, anaerobic pond, Aerobic Pond, nitrification and denitrification pond, sludge-tank etc.
During the rotation of the utility model impeller body, can make the pool inner water body obtain radially plug-flow and axial circulation fluidised form, form eddy current.Existing oar blade type agitator arm has: stir no dead angle, mixing efficiency height; Automatic deviation correction does not have location bearing at the bottom of the pond, the reliability height; Power consumption is 2-3W/m only
3, energy consumption is low; Revolution shape, antiwind; Nonmetal thin-wall construction, in light weight, corrosion-resistant.Especially the stirring of the regulating reservoir in the suitable water treatment process, anaerobic pond, Aerobic Pond, nitrification and denitrification pond, sludge-tank etc. with mix.
