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
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, city domestic sewage discharge capacity is rapid growth.Once warning prediction in " foundation of China's city domestic sewage forecasting of discharged quantity in 2020 and freshwater resources wealth GDP index " literary composition, within 2020, China's city domestic sewage discharge capacity will reach 41024 × 1010 t, and environmental pressure will be very large.Country pays much attention to sewage disposal and discharge, in " 12 " planning, explicitly points out, and improves energetically town domestic sewage and garbage disposal ability, and by 2015, treatment rate of domestic sewage and level of harmless treatment rate of life waste reached respectively 85% and 80%.From 1998, city domestic sewage discharge capacity exceeded discharged volume of industrial waste water, municipal sewage treatment cause develops rapidly, at the bottom of ending the third season in 2011, and 3078 of built sewage treatment plants of China, sewage disposal total capacity reaches 1.36 hundred million tons/day, and actual treatment ability is about 1.1 hundred million tons/day.
Sewage disposal mixer is as a kind of important sewage disposal Mixing Machine, and it is that a kind of novel diving is processed mixing plant, is applicable to city and rural sewage treatment field, is widely used in the biochemical reaction tanks such as anaerobic pond, sedimentation basin and aeration tank.Sewage disposal mixer stirs cesspool, makes pond inner fluid average speed remain on 0.3m/s left and right, and the activated sludge that is rich in microorganism in pond is suspended in pond, and microorganism fully reacts with sewage, reaches mix and blend effect.At present, the sewage disposal mixer generally using is both at home and abroad single impeller mixer, on a submersible motor, an impeller is installed, and the number of blade is generally three or two.In the time that pond is larger, many sewage disposal mixers are installed in position that just can only be inner suitable in pond, jointly stir and reach stirring requirement.Complexity is installed, wastes time and energy, improved cost.
Through retrieval, the relevant patent of declaring has at present: with the diving mixer of cutting function, and application number 201020295726.X; Glass fiber reinforced plastic diving thrust impeller of agitator, application number 200320126437.7.These patents, main by improving existing blade material, increase impeller accessory and improve mixer performance.
Summary of the invention
The object of the invention is to overcome the defect that multiple sewage disposal mixers need to be installed when larger in current pond, a kind of back of the body formula bilobed wheel sewage disposal mixer is provided, in large pond, only need a sewage disposal mixer is installed, can reach stirring requirement.
A kind of sewage disposal mixer, comprise Dual-output shaft motor, be located at Dual-output shaft motor two output shaft ends power transmission shaft, be located at the bearing block of power transmission shaft periphery and prevent that sewage from entering the mechanical sealing base of mixer inner chamber, impeller A and impeller B are positioned at the both sides of described Dual-output shaft motor, described impeller A is connected with power transmission shaft respectively with described impeller B, and described impeller A is identical with described impeller B shape size and torsional direction is contrary.
The invention has the advantages that: compared with the sewage disposal mixer of the single impeller of same diameter, this Novel back formula bilobed wheel sewage disposal mixer stirs sewage volume and will double, plug-flow distance and stirred volume obviously increase, mixing effect obviously strengthens, can be applicable to larger pond, cost when this has saved sewage disposal, only needs that a sewage disposal mixer is installed and just can meet sewage disposal requirement, save the set-up time, time saving and energy saving.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, a kind of sewage disposal mixer, comprise Dual-output shaft motor 5, be located at 5 liang of output shaft ends of Dual-output shaft motor power transmission shaft 3, be located at the bearing block 4 of power transmission shaft 3 peripheries and prevent that sewage from entering 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 Dual-output shaft motor 5, and described impeller A 1 is identical with impeller B6 shape size and torsional direction is contrary.
Implement time of the present invention, first choose on request suitable submersible motor, transform as two shaft submersible motors 5; On impeller A 1 and impeller B6, can be arranged to two blades, also can be arranged to the blade twist opposite direction of three blades and two impellers; The blade shape of two impellers designs according to lift line theory, chooses suitable NACA4406-NACA4415 wing, and two broad in the middle is little.Vane thickness is even attenuate from root to top, aerofoil profile length evenly shortens from root to top, and the runner of this distortion airfoil fan more can meet current characteristics of streamline, guarantees good hydraulic performance, to realize better, water is done work, make water obtain the object of more energy.
First manufacture impeller wooden model according to design, adopt sand casting to carry out moulding by casting, wherein adopt ripe pouring technology, strict guarantee casting quality.Then cast blade.And to the part of needs processing, reserve enough allowance.Choose suitable wheel hub, in order to facilitate installing/dismounting and maintenance, blade bolt is fastened on the relevant position on wheel hub.
While installation as Fig. 2, first utilize the guide rod 7 that is arranged on sewage disposal mixer upper end that sewage disposal mixer 8 is placed on to middle part, pond, be seen as and turn clockwise from impeller A 1 import.As shown in Figure 3, impeller A 1 advances sewage left vertically, and radial diffusion, with the interact reflux cycle of formation water of the fluid of speed and pool wall of pool A9.Impeller B6 advances sewage to the right vertically, and radial diffusion, with the interact reflux cycle of formation water of the fluid of speed and pool wall of pool B11.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 for the treatment of tank inner fluid distributes axisymmetricly along sewage disposal mixer 8 axles substantially, at the bottom of pond 10 with pond in fluid fully exchange, activated sludge is suspended in treatment tank, contact fully reaction with microorganism, reach the effect of sewage disposal.
