Beneficial effect:
The invention provides a kind of three-dimensional corner thruster that is installed on oxidation ditch or other form aeration tank angle positions, replace being installed on the underwater propeller of straight channel, because head loss is minimum on the straight channel, the underwater propeller that is 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 that is 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-conservation reaching 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, can not produce the flow velocity dead angle, can not produce sludge settling, because its fluidised form constant speed is steady, can not damage aerator in the pond because of eddy flow.The even laminar flow of thruster generation can at utmost prolong the residence time of air bubble in oxidation ditch and aeration tank mixed solution that aerating system produces in addition, improves 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 the consumable accessory installation and maintenance very convenient under water.Driving part is connected with main shaft by the motor reducer coupling shaft, main shaft connects with the thruster main body, the connection of key position adopts shaft coupling to connect, thereby solved the larger problem of moment moment of torsion when starting, the thruster main body perpendicular to the pond at the bottom of to 4～4.5 meters under water, bottom and the synchronous plug-flow of the water surface are without any the dead band during operation.
The attainable technical superiority of the present invention has: (1) can put forward the soft all thrust of perseverance of three-dimensional depth at oxidation ditch and aeration tank, and the release rate gradient increases mixing efficiency; (2) the three-dimensional corner thruster perfection incorporates oxidation ditch and aeration tank system, can realize denitration at oxidation ditch and zone, aeration tank; (3) three-dimensional corner thruster is installed in rotation angle position, so that oxidation ditch and aeration tank have more space that aerator is installed; (4) this corner thruster can increase the about 0.5～1.0m of the oxidation ditch depth of water, so that oxidation ditch reduces floor space about 20%; (5) the corner thruster operation does not have aerosol and noise producing; (6) all more than the water surface, corner thruster is under water without consumable accessory for drive-motor, bearing, filling-up area, and parts all adopt long-lived stainless steel to make under water, and long service life is safeguarded simple and convenient.
