Abstract
The utility model relates to a new aerating turntable of mechanical aerator used for oxidation ditch of sewage treatment, which is characterized in that the waterside surface of each convex block of the convex block line is in serration; a plurality of trigonal concave gloves are equably arranged on the margin of the turntable. The trigonal concave gloves have a function of pushing flow, same with the convex blocks, therefore the push force of the aerating turntable is enhanced; the height of the throwing water and the capacity of the throwing water are increased; the contacting time of the liquid film and the air; the aerating stream is increased; the power efficiency and the oxygenizing efficiency of the aerating turntable are both improved.
Description
Affiliated field; The utility model relates to the rotating disk of a kind of sewage disposal oxidation ditch with mechanical aeration equipment, particularly a kind of novel aeration turn plate.
Background technology: 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, the oxygen-transfer efficiency and the dynamic efficiency that improve aeration turn plate to greatest extent are very necessary.
The projection upstream face of existing rotating disk is facade or scarp, can only play the plug-flow effect and can not shred liquid film; In addition, the disc circumferential outer edge is uniform regular polygon shape or is uniform circular shape, can not effectively improve and throw the water height and throw the water yield, can not effectively play the plug-flow effect.
Summary of the invention: the purpose of this utility model provides a kind of high performance novel aeration turn plate, makes it have higher oxygen-transfer efficiency and dynamic efficiency.
The utility model purpose is achieved in that
The upstream face of each projection that projection is capable is a spination, the uniform triangle groove that is shaped on the circumferential outer edge of video disc.
The upstream face of the uniform triangle groove that is shaped on is the facade of triangle groove on the circumferential outer edge of described disc, and this facade is on the radial line of disc.
Advantage of the present utility model and positively effect are:
1. the utility model changes the upstream face of projection into spination by the plane, this hackly surface can go out water throwing and shred simultaneously liquid film, form the more tiny globule, increased the oxygen carrying content of the globule dramatically, thereby can improve the oxygen-transfer efficiency of aeration turn plate greatly.
2. the utility model is set up the triangle groove on the aeration turn plate circumferential outer edge, the same main plug-flow effect that plays of triangle groove with projection, set up the triangle groove after, its facade is a upstream face, thereby has strengthened 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 both improve the dynamic efficiency of aeration turn plate, improved the oxygen-transfer efficiency of aeration turn plate again.
Description of drawings:
Fig. 1 is the semicircle disc perspective view of aeration turn plate of the present utility model;
Fig. 2 is a projection perspective view of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
In Fig. 1, the uniform projection capable 3 of arrangement and the cylindrical pit 2 that between this projection is capable, is shaped on of being shaped on of the both side surface of disc 1, the upstream face of each projection that this projection is capable is a sawtooth 5, Fig. 2 is the three-dimensional structure diagram of jagged projection for upstream face, space width is generally 3～10mm, described projection can be multiple solids such as common rectangular pyramid projection, trapezoidal tapers rib projection, trapezoidal projection, triangular bump, is trapezoidal projection shown in the present embodiment.
The uniform triangle groove 4 that is shaped on the circumferential outer edge of disc, the upstream face of this triangle groove (being the facade of triangle groove) overlaps with the radial line of disc, its inclined-plane and become 50～70 degree angles with the card medullary ray.The degree of depth of triangle groove is 10～50mm, and width is 30～70mm.
Principle of work of the present utility model is:
Change the upstream face of each projection on the disc surface into spination by the plane.The effect of aeration turn plate, before the surface projection stirred water layer promotion current direction when main dependence rotating disk rotated, 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.Because the utility model changes the upstream face that disc surface is furnished with a large amount of projections into spination by the plane, this hackly surface can go out water throwing and shred simultaneously liquid film, form the more tiny globule, increase the oxygen carrying content of the globule dramatically, thereby improved the oxygen-transfer efficiency of aeration turn plate greatly.Aeration turn plate edge periphery is provided with the triangle groove.The same main plug-flow effect that plays with projection of triangle groove because the triangle groove is in the edge of aeration turn plate, has stronger thrust and centrifugal force to water layer, set up the triangle groove 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 the triangle groove 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.
Claims (2)
1. novel aeration turn plate, it is capable that the both side surface of its disc all is arranged with projection, and be distributed with cylindrical pit between this projection is capable, it is characterized in that: the upstream face of each projection that projection is capable is a spination, the uniform triangle groove that is shaped on the circumferential outer edge of disc.
2. novel aeration turn plate according to claim 1 is characterized in that: the upstream face of the uniform triangle groove that is shaped on is the facade of triangle groove on the circumferential outer edge of described disc, and this facade is on the radial line of disc.
