Abstract
The utility model relates to a pushing flow-typed aerator rotary table, wherein, a shaft hole is arranged in the disk plate. A plurality of dents and processes are arranged in both sides of the disk surface. A plurality of no-frills are arranged in circumference of the disk edge. Wherein, in order to resolve the defect that oxygenation is insufficient because current pushing flow-typed aerator rotary table push the air in the vertical plane, a plurality of no-frills are arranged in the disk edge, therefore shape of the disk is gear-shaped, which increases pushing force of the aerator rotary table and flowing pulse of the water flow in vertical diction. One result is that the parabolic water increases, which prolongs contacting time between the air and the liquid membrane. The other result is that amount of the parabolic water increases, which increases aerator wear amount. Therefore not only dynamic efficiency of the aerator rotary table is improved, but also oxygenation efficiency of the aerator rotary table is improved. The utility model improves the oxygenation ability and the flow pushing ability of wastewater.
Description
Technical field
The utility model relates to the rotating disk of a kind of sewage disposal oxidation ditch with mechanical aeration equipment, relates in particular to a kind of pulling flow type aerator rotating disk.
Background technology
The oxidation ditch bioremediation of method water be mixed solution with sewage and active sludge in oxidation ditch, utilize aerator that it is carried out plug-flow, oxygenation, the cycle operation that it is not stopped.Biological inoculums such as the aerobic microbiological of turning out and the oxygen of holding concurrently, bacterial classification is nutriment with the organic poison, carries out metabolism, carries out the effect of denitrogenation dephosphorizing simultaneously, and sewage quality is purified.Existing pulling flow type aeration turn plate is mainly arranged projection formula water-sprinkling lobe and recessed round formula storage oxygen ditch in its two sides.At present, oxidation ditch process is used widely, and the rotating disk aerator is the most critical equipment of oxidation ditch process, and the performance of aeration turn plate is the main factor that influences rotating disk aerator performance.Therefore, under the prerequisite that guarantees rotating disk mechanical property and reasonable structure, it is very necessary improving aeration turn plate rhythm oxygen-transfer efficiency and dynamic efficiency to greatest extent.
The dish edge of existing rotating disk is circular, and its plug-flow effect mainly realizes that by the projection on the card, pit the plug-flow effect is bad, can not effectively improve and throw the water height and throw the water yield.
The utility model content
The purpose of this utility model provides the rotating disk that a kind of outline is a profile of tooth, makes it have the pulling flow type aerator rotating disk of higher oxygen-transfer efficiency and dynamic efficiency.
The utility model purpose is achieved in that its disc middle part is provided with axis hole, and the both side surface of card all is arranged with some pits, projection, and dish upwards is equipped with some notches in edge week.
The skeletal lines of described notch is semi arch, major arc, minor arc, trilateral, trapezoidal, or asymmetric arc, trilateral, trapezoidal.
It is regularly arranged to the curved line of dish edge by core that some pits on the described card, projection are.
The utility model makes the oxygenation defect of insufficient for overcoming existing pulling flow type aerator rotating disk plug-flow in perpendicular, establishes some notches at the disc edge, makes dish type be gear shape, has strengthened the thrust of aerator rotating disk, increases the pulsation of current at vertical direction.Its result one throws water to increase, and has prolonged the duration of contact of liquid film and air, and the 2nd, throw the water yield and strengthen, increased the aeration water yield.Therefore both improve the dynamic efficiency of aeration turn plate, improved the oxygen-transfer efficiency of aerator rotating disk again.The utility model makes the oxygenation of sewage, and the plug-flow ability is strengthened.

Fig. 1 is the structural representation of the utility model aerator rotating disk.
1 is pit among the figure, the 2nd, and projection, the 3rd, notch, the 4th, axis hole, the 5th, disc.
Fig. 2 is the partial schematic diagram of second kind of embodiment of the utility model.
Fig. 3 is the partial schematic diagram of the third embodiment of the utility model.
Fig. 4 is the partial schematic diagram of the 4th kind of embodiment of the utility model.
Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
In Fig. 1, the uniform projection 2 of arrangement and the circular pit 1 that between these projection 2 row, is shaped on of being shaped on of the both side surface of disc 5, it is regularly arranged to the curved line of dish edge by core that projection 2, pit 1 are on the card of disc 5.Disc 5 middle parts are provided with axis hole 4, and the dish edge week of disc 5 upwards is equipped with some notches 3.Be provided with the disc 5 of notch 3, its shape is gear-like.The profile of tooth that notch 3 forms, its depth, radian, symmetry can be according to the practical situation adjustment.The skeletal lines of notch 3 can be semi arch, major arc, minor arc, trilateral, trapezoidal, or asymmetric arc, trilateral, trapezoidal.
Fig. 2, Fig. 3, Fig. 4 be of the present utility model second and third, the structural representation of four kinds of embodiments.
Principle of work of the present utility model is: before protrusion of surface stirs water layer promotion current direction when relying on the rotating disk rotation, centrifugal force by aeration turn plate goes out water surface formation liquid film with water throwing simultaneously, liquid film carries the air in the aeration turn plate surface crater, form the globule of gas-liquid mixed, the globule of dishing out contacts with atmosphere again airborne oxygen brought in and reaches the oxygenation purpose in the water.Aeration turn plate edge periphery is provided with notch 3.Notch 3 and the 2 the same main plug-flow effects that play of card upper process because notch 3 is in the edge of aeration turn plate, have stronger thrust and centrifugal force to water layer, set up notch 3 after, its facade meets water has increased the thrust of aeration turn plate.Its result one throws water to increase, and has prolonged the duration of contact of liquid film and air, and the 2nd, throw the water yield and strengthen, increased the aeration water yield.Therefore, the utility model is set up notch 3 on aeration turn plate edge periphery, both improved the dynamic efficiency of aeration turn plate, has improved the oxygen-transfer efficiency of aeration turn plate again.
