Abstract
A sewage treatment mixer is characterized by comprising a submersible motor (1), a double-output-shaft speed reducer (2), an impeller A (3) and an impeller B (4), wherein the double-output-shaft speed reducer (2) is connected with the submersible motor (1), and the impeller A (3) and the impeller B (4) are connected with two output shafts of the double-output-shaft speed reducer (2) respectively. When the sewage treatment mixer is used for mixing sewage, four greater circulations are formed in a water tank under interaction of the two impellers and walls of the water tank, the mixing width is obviously increased, the mixing volume is greatly increased, the mixing effect is obviously enhanced, energy is saved as one motor drives the two impellers through the speed reducer, the two impellers are symmetrically arranged, and the sewage treatment mixer is high in stability and is safe and reliable when running.
Description
Technical field
The present invention relates to a kind of sewage disposal mixer, refer in particular to a kind of new type double impeller sewage disposal mixer.
Background technology
Along with industrial develop rapidly, the water resource pollution of China is more serious, and country pays much attention to the control of environment.Especially aspect sewage disposal, China spells out in " 12 " planning, improves town domestic sewage and garbage disposal ability energetically, and by 2015, treatment rate of domestic sewage and level of harmless treatment rate of life waste were with reaching 85% and 80% respectively.Sewage disposal is the important measures that current environmental administration and enterprise solve contaminated wastewater in the environmental pollution; Wherein, The sewage disposal mixer is a kind of important sewage disposal Mixing Machine; Be applicable to city and country sewage processing field, be widely used in biochemical reaction tanks such as anaerobic pond, sedimentation basin and aeration tank.The pond that mixer stirs, pond inner fluid average speed remains on about 0.3m/s, is rich in the activation of microorganism sludge suspension in the pond in the pond, and microorganism and sewage fully react, and reach the mixing stirring action.According to situation such as the actual scale of Sewage Plant, landform, the kind in pond is also a lot, and washing basin is arranged, big pond, fountain square, round pool, shapes such as rectangle pond.
At present, the domestic sewage disposal mixer that generally uses is the single impeller mixer, promptly on a submersible motor impeller is installed, and the number of blade is generally three or two.When the pond is big, just can only inner suitable position be installed by many sewage disposal mixers in the pond, come common the stirring to reach the stirring requirement.Complicacy is installed, wastes time and energy, improved cost.
Through retrieval, the relevant at present patent of declaring has: the diving mixer of band cutting function, application number 201020295726.X; Fiberglass diving pulling flow type Agitator Impeller, application number 200320126437.7.These patents, main through improving existing blade material, increase the impeller accessory and improve the mixer performance.
Summary of the invention
The objective of the invention is to overcome the defective that present fountain square need be installed a plurality of sewage disposal mixers when big, a kind of new type double impeller sewage disposal mixer is provided, in square big pond, only need a mixer is installed, can reach the stirring requirement.
A kind of sewage disposal mixer, the double output shaft decelerator that comprise submersible motor, links to each other and two identical impeller A and impeller B with submersible motor, said impeller A is connected with two output shafts of double output shaft decelerator respectively with impeller B.
The invention has the advantages that: when the present invention stirs sewage, under two impellers and pool wall of pool interaction, formed four systemic circulations in the pond; Mixing width obviously increases, and stirred volume will increase greatly, and mixing effect obviously strengthens; Drive two impellers with a motor through decelerator, practiced thrift energy, and the device symmetry; Stability is high during operation, and is safe and reliable.

Fig. 1 is a sewage disposal mixer structural representation.
Fig. 2 is a sewage disposal Agitator Impeller shape sketch map.
Fig. 3 is the scheme of installation of sewage disposal mixer.
Streamline sketch map when Fig. 4 is the operation of sewage disposal mixer.
Among the figure, 1, submersible motor, 2, the double output shaft reductor, 3, impeller A, 4, impeller B, 5, guide rod, 6, the sewage disposal mixer.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
As shown in Figure 1; A kind of sewage disposal mixer; Comprise submersible motor 1, the double output shaft that links to each other with submersible motor 1, identical impeller A 3 of decelerator 2 and two and impeller B4, said impeller A 3 is connected with two output shafts of double output shaft decelerator 2 respectively with impeller B4.
As shown in Figure 2, the blade shape of impeller A 3 and impeller B4 designs according to lift line theory, and it is wing to choose suitable NACA4406-NACA4415, and two broad in the middle is little.Vane thickness is even attenuate from the root to the top; Aerofoil profile length evenly shortens from the root to the top, and the runner of this distortion airfoil fan more can meet current streamline characteristic, guarantees good hydraulic; To realize better making water obtain the purpose of more energy to the water acting.
Make earlier the impeller wooden model according to design, adopt sand casting to carry out moulding by casting, wherein adopt ripe pouring technology, strict guarantee casting quality.Cast blade then.And the part to needs processing reserves enough allowance.Choose suitable wheel hub, installing/dismounting and maintenance for ease crossed bolted to wheel hub with blade pass.
When installing, at first utilize the guide rod 5 be installed in sewage disposal mixer upper end that sewage disposal mixer 6 is placed on pond Bian Bi, be seen as from impeller A 3 imports and turn clockwise like Fig. 3.Can know that like Fig. 4 impeller A 3, impeller B4 push ahead sewage vertically, radial diffusion has the fluid of speed and the reflux cycle that the pool wall of pool interaction forms water.Wherein, the water at middle part, pond will be shunted under the effect of impeller A 3, impeller B4, sucked by impeller A 3, impeller B5 respectively, and acting, acquisition speed axially advances once more, forms circulation.Tradition can only form two systemic circulations with the flow field of the single impeller sewage disposal mixer stirring of diameter, and the radial diffusion width is less.The present invention is under two impellers and pool wall of pool interaction; The axial advance variable in distance is little, but has formed four systemic circulations in the pond, and mixing width obviously increases; Fluid in the pond fully exchanges; Activated sludge is suspended in the treatment tank, with the reaction of microorganism full contact, reaches the effect of sewage disposal.
