Description
Technical field
The present invention relates to the inversed umbrella type composite impeller surface aeration machine that a kind of sewage disposal is used.
Background technology
The inversed umbrella type surface aeration machine is the key equipment that the city sewage treatment works oxidation ditch uses, all impellers of traditional inversed umbrella type surface aeration machine, its shape all resembles one and is falling the paper shape umbrella of opening, be installed in the water surface of oxidation ditch, adopt mechanical reduction to drive rotation, scrape the water plug-flow by several blades on the impeller and hold under the arm and wrap up in air, reach the water purifying purpose by oxygen dissolution water oxygen organism.Because blade can only push away water and rotate, blade bump water causes bubble cracked, flows to disorder, is difficult to improve after surperficial dissolved oxygen reaches certain value again, and it is not fine causing the aeration effect, and dynamic efficiency is low, generally can only reach 1.6-2.4kgO
2/ kWh the highlyest also can only reach 2.5-2.6kgO
2/ kWh makes the energy consumption cost in China's municipal sewage treatment cost high.
Summary of the invention
The invention provides and a kind ofly can improve oxygen-transfer efficiency, the inversed umbrella type composite impeller surface aeration machine that power usefulness is high greatly.
Technical scheme of the present invention is as follows: inversed umbrella type composite impeller surface aeration machine, motor and speed reducer connects with impeller body by transmission connection piece, impeller body is for falling umbrella, blade is fixed on the impeller body radially, be evenly equipped with the gas-liquid mixed pipe radially on the outer convex surface of cone more than the described impeller body skeleton supporting face, the impeller body of the inner ingress of gas-liquid mixed pipe is provided with air-breathing through hole.
In the present invention, be provided with air-breathing through hole between the crack of adjacent gas-liquid mixed pipe; The either side of described blade or the impeller body of both sides are provided with a plurality of air-breathing through holes; The radial section of described gas-liquid mixed pipe is trilateral, semicircle, circle or rectangle.
The upper surface of described blade or lower surface are dentation, and perhaps upper and lower end face is dentation.
Described transmission connection piece comprises shaft coupling, the lower end of shaft coupling is arranged in the central through hole of impeller body, the diameter of central through hole is greater than the diameter of shaft coupling lower end, evenly is fixed with several vane sheets between the periphery of shaft coupling and impeller body central through hole, constitutes blade water lift mechanism.
The radial section of described blade is the plane, perhaps is folding surface, and its bending angle is between 100 degree are spent to 180; The blade edge that is positioned at the outer convex surface of impeller body linearly or arc shaped.
After adopting as above technical scheme, when the impeller body high speed rotating, the impeller cone is being pressed the water surface, water is just thrown out by centrifugal force from the gas-liquid mixed pipe, the inner of gas-liquid mixed pipe becomes negative pressuren zone simultaneously, air just enters the gas-liquid mixed pipe from the negative inspiratory pressure through hole of the impeller body of gas-liquid mixed pipe the inner, so water, gas are thrown away behind the thorough mixing in the gas-liquid mixed pipe continuously, has improved aeration aerating efficient greatly.Crevice place between the gas-liquid mixed pipe also is a negative pressuren zone, and by the air-breathing through hole that this place is provided with, water is carrying out mixing fully with gas, has further improved oxygen-transfer efficiency again.During the blade rotation, also can form negative pressuren zone in blade one side, the impeller body of negative pressuren zone is provided with the air inlet through hole, has also improved oxygen-transfer efficiency.When the upper and lower end face of blade is dentation, the water of contact with it there is combing effect, plays the effect of rectification, current stabilization, the current attitude after the oxygenation is improved.Be provided with blade water lift mechanism between impeller body central through hole and the shaft coupling lower end periphery, the water at rotation center position is upwards rolled, the water in centre just can fully stir oxygenation like this, has eliminated the blind area, center of aerator oxygenation.The present invention has made full use of the locus of impeller with mechanical movement principle and the ingenious combination of liquid motion principle, has improved oxygen-transfer efficiency, compares with traditional surface aeration machine, and dynamic efficiency reaches 4.0kgO
2/ kWh, dynamic efficiency has improved more than 70%, thus the energy consumption cost that has reduced sewage disposal is more than 50%.
