Technical field
The invention belongs to field of sewage treatment equipment, relate to a kind of three-dimensional corner thruster, be specifically related to a kind of oxidation ditch or aeration tank bend thruster.
Background technology
In urban sewage treatment process, the stirring of mixed solution, hybrid propulsion are critical processes wherein, and that applies at present mostly is the horizontal double bladed paddle of impeller shaft, leafy slurry agitator etc., the structure formation of these blades, for specifically stirring demand, all play a role.Such as, but more or less come with some shortcomings: stirring region local velocity is excessive, plug-flow scope is little, the mud group through impeller is easily broken; There is certain stirring dead angle, cause sludge settling; The fluidised form that tradition underwater propeller produces be turbulent flow, and there is backflow in most of region, backflows, helical flow phenomenon, and plug-flow region flow velocity inequality, causes energy loss; The air bubble rapid aggregation that underwater propeller helical flow can impel aerating system to produce fast merges, and reduces aerating system oxygen transfer efficiency; Advance the energy consumption that consumes higher, power density is comparatively up to 5 ~ 8W/m
3; In addition, drive-motor, step-down gear safeguard that more difficult, impeller is easily linked with impurity and causes overload fault under water.
Summary of the invention
The object of the invention is the above-mentioned deficiency for prior art, a kind of three-dimensional corner thruster is provided.
Object of the present invention realizes by following technical scheme:
A kind of three-dimensional corner thruster, comprises driving part, main shaft, thruster main body; Driving part comprises parallel-shaft bevel wheel reducer, motor coupling shaft, pin coupler from top to bottom successively; Uniform guide vane in described thruster main body, motor coupling shaft upper end is connected with parallel-shaft bevel wheel reducer, motor coupling shaft lower end is connected by pin coupler with between main shaft, and main shaft is connected with thruster main body, drives thruster main body to rotate in fluid medium.
The sheet number of described guide vane is 12 ~ 25, preferably 15 ~ 20, preferably 16, in radiation horn shape.
Described guide vane and the angle of the alignment of shafts are 10 ° ~ 30 °.
Described driving part is fixedly installed on the horizontal part of erection bridge.Support is not established, under water without consumable accessory bottom three-dimensional corner thruster.On the stressed support erection bridge of whole weight.
Described erection bridge is also provided with a vertical corner flow deflector.
Described erection bridge is concrete foundation or Steel Bracket.
Beneficial effect:
The invention provides a kind of three-dimensional corner thruster being installed on oxidation ditch or other form aeration tank angle positions, replace the underwater propeller being installed on straight channel, because head loss is minimum on straight channel, the underwater propeller being installed on this can only form general puopulsion efficiency, and the nook head loss of oxidation ditch or aeration tank is maximum, the three-dimensional corner thruster of the present invention being assemblied in this can form the highest puopulsion efficiency, thrust power can be passed to oxidation ditch or aeration tank section along the channel degree of depth expeditiously, its power density can reach 1.6 ~ 2.0W/m
3, energy-conservationly reach more than 50 ~ 60%.Three-dimensional corner thruster of the present invention runs on oxidation ditch and aeration tank, and mixed solution is produced without turbulent flow rate, the balanced fluidised form of gradient, flow velocity dead angle can not be produced, can not sludge settling be produced, because its fluidised form constant speed is steady, the aerator in pond can not be damaged because of eddy flow.The even laminar flow of thruster generation in addition, at utmost can extend the residence time of air bubble in oxidation ditch and aeration tank mixed solution that aerating system produces, improve the oxygen-transfer efficiency of aerating system.This three-dimensional corner thruster power system is installed on oxidation ditch and the aeration tank water surface, does not have consumable accessory installation and maintenance very convenient under water.Driving part is connected with main shaft by motor reducer coupling shaft, main shaft connects with thruster main body, the connection of key position adopts shaft coupling to connect, thus the problem that when solving startup, instantaneous torque is larger, thruster body normal is to 4 ~ 4.5 meters under water at the bottom of pond, and bottom during operation, plug-flow synchronous with the water surface is without any dead band.
The attainable technical superiority of the present invention has: (1) can put forward the soft all permanent thrust of three-dimensional depth at oxidation ditch and aeration tank, and release rate gradient, increases mixing efficiency; (2) three-dimensional corner thruster perfection incorporates oxidation ditch and aeration tank system, can realize denitration at oxidation ditch and region, aeration tank; (3) three-dimensional corner thruster is arranged on rotation angle position, makes oxidation ditch and aeration tank have more space to install aerator; (4) this corner thruster can increase the oxidation ditch depth of water about 0.5 ~ 1.0m, makes oxidation ditch reduce floor space about 20%; (5) corner thruster runs does not have aerosol and noise to produce; (6) drive-motor, bearing, filling-up area are all more than the water surface, and corner thruster is under water without consumable accessory, and parts all adopt long-lived stainless steel to make under water, and long service life is safeguarded simple and convenient.
