Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a flocculation reaction mixer for sewage treatment. Background Art
[0002] Wastewater treatment is an important environmental engineering process that aims to remove pollutants from water to protect water resources and the environment. Sewage is converted into a reusable water source through treatment. Specific pollutants in sewage can be removed by adding flocculants for reaction. Flocculation reaction mixers play an important role in sewage treatment and other chemical industries. They are mainly used to promote flocculation reactions, help particles aggregate to form larger flocs, and thus achieve solid-liquid separation.
[0003] The flocculation reaction mixer disperses the flocculant into the sewage to be treated through mechanical stirring, promotes the mutual contact and combination of particles, and forms larger flocs. After the flocculant is injected into the sewage, it will be distributed at different heights of the sewage. The curved impeller set in the mixer can only stir the sewage and flocculant at the bottom. Therefore, the stirring range of the flocculant is relatively limited, which may lead to insufficient contact between the flocculant and the sewage and inability to achieve uniform mixing. Uneven mixing will cause the flocculant concentration in some areas to be too high, while the concentration in other areas is insufficient, thereby affecting the flocculation effect. For this reason, it is particularly important to design a flocculation reaction mixer for sewage treatment. Utility Model Content

[0021] See also Figure 1-4 The utility model provides a technical solution of a flocculation reaction mixer for sewage treatment:
[0022] Example 1:

First vertical rods 10 are arranged at the bottom of the four arc plates 9, and inclined rods 13 are arranged on one side of the four arc plates 9. As the arc plates 9 rotate, the first vertical rods 10 and the inclined rods 13 are driven to rotate simultaneously. The inclined rods 13 with an inclined angle increase the area for stirring the sewage and flocculant, improve the reaction efficiency, and shorten the flocculation reaction time. The curved impeller 3 can stir the sewage and flocculant at the bottom.
[0024] Example 2:
[0025] Based on the first embodiment, Figure 1 and Figure 4As shown, a third vertical rod 15 is fixedly installed at the bottom of the four arc-shaped plates 9, and the length of the four third vertical rods 15 is greater than the length of the four second vertical rods 14. A limiting shaft 12 is provided on the top of the four inclined rods 13, and an L-shaped block 11 is fixedly installed on one side of the four arc-shaped plates 9. The utility model provides a flocculation reaction mixer for sewage treatment. By providing an embedded rod 7, a limiting shaft 12, a second vertical rod 14 and a third vertical rod 15, the auxiliary sleeve 5 and one end of the stirring bar 2 are fixedly sleeved. As the stirring bar 2 rotates, the auxiliary sleeve 5 and the two arc-shaped frames 6 are driven to rotate synchronously, and the lengths of the second vertical rod 14, the third vertical rod 15 and the first vertical rod 10 increase successively.
[0026] Working principle: Sewage treatment is an important environmental engineering process, which aims to remove pollutants in water to protect water resources and the environment. Sewage is converted into reusable water source through treatment. Specific pollutants in sewage can be removed by adding flocculants for reaction. Flocculation reaction mixer plays an important role in sewage treatment and other chemical industries. It is mainly used to promote flocculation reaction and help particles to aggregate to form larger flocs, thereby realizing solid-liquid separation. The flocculation reaction mixer disperses the flocculant into the sewage to be treated through mechanical stirring, promotes mutual contact and combination between particles, and forms larger flocs. After the flocculant is injected into the sewage, it will be distributed at different heights of the sewage. The curved impeller 3 set in the mixer can only stir the sewage and flocculant at the bottom position. Therefore, the stirring range of the flocculant is relatively limited, which may lead to insufficient contact between the flocculant and the sewage, and it is impossible to achieve uniform mixing. Uneven mixing will cause the flocculant concentration in some areas to be too high, while the concentration in other areas is insufficient, thereby affecting the flocculation effect. For this purpose, a flocculation reaction mixer for sewage treatment is designed. The mixer is particularly important. The curved impeller 3 is immersed in the sewage. The pressure-resistant frame 4 can support the stirring motor 1. After starting the stirring motor 1, it drives the stirring bar 2 and the curved impeller 3 to rotate synchronously, thereby driving the four arc-shaped plates 9 to rotate synchronously. As the arc-shaped plates 9 rotate, the first vertical rod 10 and the inclined rod 13 are driven to rotate at the same time. The inclined rod 13 with an inclined angle increases the area for stirring the sewage and flocculant, improves the reaction efficiency, and shortens the flocculation reaction time. The curved impeller 3 can stir the sewage and flocculant at the bottom. The auxiliary sleeve 5 is fixedly mounted on one end of the stirring bar 2. As the stirring bar 2 rotates, the auxiliary sleeve 5 and the two arc-shaped frames 6 are driven to rotate synchronously. The lengths of the second vertical rod 14, the third vertical rod 15 and the first vertical rod 10 increase successively. The three can stir the flocculants at different heights. The L-shaped block 11 and the tilted rod 13 are connected by a limiting shaft 12. As the arc plate 9 moves, the tilted rod 13 also moves, which increases the area of the mixer stirring the flocculant and makes the flocculant and sewage mixed more evenly.
