Abstract
The utility model discloses an aerator with rotating claws. The aerator comprises a motor, a reducer, a coupling, a rotating shaft and rotating claws; the motor is connected with the coupling through the reducer; the rotating shaft is fixedly connected to the coupling; the rotating claws are fixed on the surface of the rotating shaft according to rotating trace in such a manner that adjacent claws are different in length; each rotating claw comprises a claw body and a claw head; the claw bodies are fixed on the rotating shaft; and the claw heads adopt pointed heads in the same rotating direction. Preferably, all the pointed heads adopt clockwise rotating direction. When in operation, air and water can be fully dissolved and mixed, so that the utility model has the advantages that oxygen in air can be fully used, the optimum effect of aeration and oxygenation is achieved; the work efficiency is improved; and the power consumption is saved. The utility model further has the advantages of simple and reasonable structural design, convenient installation, low cost, and high applicability.
Description
Technical field
The utility model relates to the surface aeration equipment in a kind of sewage treatment area, is a kind of commentaries on classics pawl aerator that is used for sewage disposal specifically.
Background technology
Aerator is the key equipment in the city sewage treatment works, and sewage work's surface aeration great majority adopt plate-spinning, brush aeration machine to carry out oxygenic aeration at present.Any mechanical aeration machine no matter, its principle of work all is to drive rotation by mechanical reduction, scrapes the water plug-flow by some blades on the impeller, wraps air, makes air and the effect of water body thorough mixing, oxygen dissolution water oxygen organism reaches the water purifying purpose.Because blade can only push away water and rotate, blade bump water causes bubble cracked, flows to disorderly.Be difficult to improve after the surface melts oxygen to reach certain value again, cause the aeration effect bad, power usefulness is low, inefficiency.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of aeration ability is good, the commentaries on classics pawl aerator of high efficiency.
Technical scheme: for solving the problems of the technologies described above, this use is novel has adopted following technical scheme, a kind of commentaries on classics pawl aerator, it comprises electric motor, speed reduction unit, shaft coupling, rotating shaft and commentaries on classics pawl, electric motor links to each other with shaft coupling by speed reduction unit, be fixedly connected with rotating shaft on the shaft coupling, it is alternate and be fixed on the surface of rotating shaft by helical trajectory to change pawl length.
Wherein, described commentaries on classics pawl comprises pawl body and pawl head, and the pawl body is fixed in the rotating shaft, and the pawl head is the tip with identical rotation direction.Preferably, described tip be dextrorotation to.
Wherein said pawl is provided with groove on one's body, and groove has alleviated the overall weight of equipment, thereby has alleviated operating load, improves the efficient of gas-vapor mix.
Beneficial effect: during the work of (1) commentaries on classics pawl of the present utility model aerator, air is fully dissolved with water mix, airborne oxygen is fully used, reach the best effect of aeration aerating, improve working efficiency, save power consumption.(2) spiral shell rotary pawl aerator structure design advantages of simple of the present utility model, easy for installation, cost is low, and suitability is strong.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be Fig. 1 A-A to enlarged diagram.
Embodiment:
As shown in Figures 1 and 2, commentaries on classics pawl aerator of the present utility model comprises electric motor 1, speed reduction unit 2, shaft coupling 3, rotating shaft 4 and commentaries on classics pawl 5 and base, and electric motor 1 links to each other with shaft coupling 3 by speed reduction unit 2, and speed reduction unit 2 is fixed on the base.Be fixedly connected with rotating shaft 4 on the shaft coupling 3, rotating shaft 4 is the step axle,, it is alternate and be fixed on the surface at step axle middle part by helical trajectory to change pawl 5 length, forms the spiral claw shaped body of concavo-convex arrangement.Change that pawl 5 can make that size differs but the identical a lot of corpus unguis of structure.Change pawl 5 and comprise pawl body 51, pawl head 52 and groove 53, pawl body 51 is fixed on the step axle, and the end of pawl body 51 is a pawl head 52, and pawl body 51 is provided with groove 53, and groove 53 can make water contact more fully with air, strengthens the aeration effect.Each pawl head 52 that changes pawl 5 all have a dextrorotation to plagiocephaly, dextrorotation to pawl head 52 convenient whole impellers partly change in the water, reduce the resistance of water to impeller.In the present embodiment, the long commentaries on classics pawl 5 of 50cm and 30cm is intervally arranged in rotating shaft 4, some commentaries on classics pawls 5 that perhaps also can be 50cm, 40cm, three kinds of sizes of 30cm are arranged in the rotating shaft 4, this concavo-convex arrangement can alleviate the overall weight of equipment, alleviate operating load, improve the gas-vapor mix effect, thereby increase oxygen-transfer efficiency.In rotary course, make air produce centrifugation along changeing pawl 5, increase the contact area of air and water, hydraulic load during reduction equipment operation simultaneously improves oxygenation capacity.Be provided with groove simultaneously on commentaries on classics pawl 5, groove 53 has also alleviated the overall weight of equipment, thereby has alleviated operating load, and improves the efficient of gas-vapor mix, can make water that bigger surging force be arranged in the rotary course kind, thereby strengthens oxygenation capacity.
During the operation of commentaries on classics pawl aerator, drive unit drives changes pawl 5 rotations, and commentaries on classics pawl 5, enters successively and produces even power in the water by certain helical trajectory with air, has reduced the stressed load of equipment; Make air and water in pawl type shape body, produce certain reactive force under the turning effort simultaneously, and diffusion from inside to outside, thereby improve oxygenation capacity, dynamic efficiency widely and reduced running cost.In addition, by changeing the running of pawl 5, promote sewage and in oxidation ditch, circulate with certain flow velocity, can prevent the precipitation of active sludge, organism, microorganism are contacted with the oxygen thorough mixing, thereby effectively reach the needs of oxidation ditch process mixing, oxygenation.
The utility model provides a kind of thinking and method of changeing the pawl aerator; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
