Abstract

The invention discloses a sewage treatment mixer. The sewage treatment mixer is characterized by comprising a dual-output shaft motor (5), transmission shafts (3) arranged at the two output shaft ends of the dual-output shaft motor (5), bearing seats (4) arranged at the peripheries of the transmission shafts (3), a mechanical sealing seat (2) for preventing sewage from flowing into an inner cavity of the mixer, an impeller A (1) and an impeller B (6), wherein the impeller A (1) and the impeller B (6) are located on the two sides of the dual-output shaft motor (5), are connected with the transmission shafts (3), and have the same shape and size and opposite torsion direction. According to the invention, the mixing requirements can be met by mounting one sewage treatment mixer in a big water pool only.

Description

A kind of sewage disposal mixer
Technical field
The present invention relates to a kind of sewage disposal mixer, refer in particular to a kind of back of the body formula bilobed wheel sewage disposal mixer.
Background technology
Follow fast urbanization in current china, the city domestic sewage discharge capacity is quick growth.Once warning prediction in " foundation of China's city domestic sewage discharge capacity prediction in 2020 and freshwater resources wealth GDP index " literary composition, China's city domestic sewage discharge capacity will reach 41024 * 1010 t in 2020, and environmental pressure will be very big.Country pays much attention to sewage disposal and discharging, in " 12 " planning, spells out, and 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 reached 85% and 80% respectively.Surpass discharged volume of industrial waste water from city domestic sewage discharge capacity in 1998; The municipal sewage treatment cause develops rapidly, at the bottom of the third season in 2011, and 3078 of built in China sewage treatment plants; The sewage disposal total capacity reaches 1.36 hundred million tons/day, and the actual treatment ability is about 1.1 hundred million tons/day.
The sewage disposal mixer is as a kind of important sewage disposal Mixing Machine, and it is that a kind of novel diving is handled mixing plant, is applicable to city and country sewage processing field, is widely used in biochemical reaction tanks such as anaerobic pond, sedimentation basin and aeration tank.The sewage disposal mixer stirs cesspool, makes pond inner fluid average speed remain 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.At present, the sewage disposal mixer that generally uses both at home and abroad 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 a plurality of sewage disposal mixers need be installed when big in present pond, a kind of back of the body formula bilobed wheel sewage disposal mixer is provided, in big pond, only need a sewage disposal mixer is installed, can reach the stirring requirement.
A kind of sewage disposal mixer; Comprise the double output shaft motor, be located at double output shaft motor two output axle heads power transmission shaft, be located at the bearing block of power transmission shaft periphery and prevent that sewage from getting into the mechanical sealing base of mixer inner chamber; Impeller A and impeller B are positioned at the both sides of said double output shaft motor; Said impeller A is connected with power transmission shaft respectively with said impeller B, and said impeller A is identical with said impeller B shape size and torsional direction is opposite.
The invention has the advantages that: compare with the sewage disposal mixer with the single impeller of diameter, this novel back of the body formula bilobed wheel sewage disposal mixer stirs the sewage volume and will double, and plug-flow distance and stirred volume obviously increase; Mixing effect obviously strengthens; Can be applicable to big pond, the cost when this has practiced thrift sewage disposal only needs that a sewage disposal mixer is installed and just can satisfy the sewage disposal requirement; Practiced thrift the set-up time, time saving and energy saving.

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 double output shaft motor 5, be located at 5 liang in double output shaft motor output axle head power transmission shaft 3, be located at the bearing block 4 of power transmission shaft 3 peripheries and prevent that sewage from getting into the mechanical sealing base 2 of mixer inner chamber; Impeller A 1 is connected with power transmission shaft 3 respectively with the both sides that impeller B6 is positioned at double output shaft motor 5, and said impeller A 1 is identical with impeller B6 shape size and torsional direction is opposite.
During embodiment of the present invention, choose earlier suitable submersible motor on request, transform them as two shaft submersible motors 5; Can be arranged to two blades on impeller A 1 and the impeller B6, the blade twist that also can be arranged to three blades and two impellers is in the opposite direction; The blade shape of two impellers 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, with the blade bolted on the relevant position on the wheel hub.
When installing, at first utilize the guide rod 7 be installed in sewage disposal mixer upper end that sewage disposal mixer 8 is placed on the middle part, pond, be seen as from impeller A 1 import and turn clockwise like Fig. 2.As shown in Figure 3, impeller A 1 advances sewage left vertically, and radial diffusion has the fluid of speed and the reflux cycle that pool wall of pool A9 interaction forms water.Impeller B6 advances sewage to the right vertically, and radial diffusion has the fluid of speed and the reflux cycle that pool wall of pool B11 interaction forms water.Under the interaction of two impellers and pool wall of pool A9 and pool wall of pool B11; Whole pond inner fluid fully circulates; And the flow velocity of treatment tank inner fluid distributes along 8 in sewage disposal mixer basically axisymmetricly, at the bottom of the pond 10 with the pond in fluid fully exchange, activated sludge is suspended in the treatment tank; With the reaction of microorganism full contact, reach the effect of sewage disposal.
