Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a stirring device for a sewage treatment flocculant. Background Art

[0002] The flocculation precipitation method is to select inorganic flocculants (such as aluminum sulfate) and organic anionic flocculants polyacrylamide (PAM) to prepare aqueous solutions and add them to wastewater, which will produce a compressed double layer, making the suspended particles in the wastewater lose stability, and the colloids coagulate each other to increase the size of the particles, forming floccules and alum flowers. After the floccules grow to a certain volume, they will separate from the water phase and precipitate under the action of gravity, thereby removing a large amount of suspended matter in the wastewater, thereby achieving the effect of water treatment. At present, when using flocculants for sewage treatment, it is easy to have insufficient stirring and mixing, and at the same time, there will be too much flocculant injection, which will cause the flocculant to agglomerate, which is not conducive to sewage treatment. Therefore, a stirring device for sewage treatment flocculants is proposed to solve the problems described in the above background technology.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0009] Preferably, the bevel gear 1 is fixed on the rotating shaft, the ends of the stirring shafts on both sides extend into the driving box, and the two bevel gears 2 are respectively fixed on the ends of the stirring shafts on both sides.

[0010] Preferably, the motor is transmission-connected to the rotating shaft, and the two bevel gears 2 are meshed with the bevel gear 1.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By designing a stirring mechanism, during sewage treatment, the motor drives the rotating shaft to rotate, so that the rotating shaft drives multiple drive boxes to rotate. At this time, the sewage is stirred and mixed by the stirring rods on both sides of the multiple drive boxes. When the rotating shaft rotates, it drives the bevel gear 1 to rotate, and the bevel gear 1 meshes with the two bevel gears, so that the bevel gear 1 drives the two bevel gears 2 to rotate, thereby driving the stirring shafts on both sides to rotate through the two bevel gears 2, so that the stirring shafts on both sides drive multiple material-pickling rods to mix and stir the sewage. Compared with the prior art, this design can perform multiple stirring on the injected flocculant, thereby improving the efficiency of flocculant dissolution and avoiding agglomeration.

[0013] 2. By designing an injection mechanism, during sewage treatment, the flocculant is injected into the storage barrel through the injection port, and then the cross bar is driven to rotate through the rotating shaft, so that the cross bar pushes the movable ring to rotate through the protrusion. When the movable ring rotates, the sealing plate is driven to rotate a quarter of a turn through the connecting rod. When the sealing plate rotates one circle, the flocculant inside the storage barrel is injected into the sewage barrel. Compared with the existing technology, this design can automatically and intermittently inject materials, thereby reducing the workload of workers. At the same time, it also allows the flocculant to be fully dissolved in the sewage, thereby avoiding agglomeration caused by excessive injection. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the sewage is stirred and mixed by the stirring rods 9 on both sides of the multiple driving boxes 8. When the rotating shaft 7 rotates, it will drive the bevel gear 12 to rotate, and the bevel gear 12 will mesh with the two bevel gears 2 13, so that the bevel gear 12 drives the two bevel gears 2 13 to rotate, thereby driving the stirring shafts 10 on both sides to rotate through the two bevel gears 2 13, so that the stirring shafts 10 on both sides drive the multiple material tapping rods 11 to mix and stir the sewage.
