Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a foam driving device for a sewage treatment pool. Background Art

[0002] Sewage generally refers to polluted water from domestic and industrial sources. It primarily includes domestic sewage, industrial wastewater, and initial rainwater. The main pollutants in sewage include pathogens, oxygen-depleting pollutants, plant nutrients, and toxic pollutants. During the production and living processes, pollutants such as wastewater and scum are generated. During the treatment process at sewage treatment plants, organic matter and oil are present in the collected sewage. These organic matter and oil are oxidized and decomposed during the treatment process, generating gases and, in turn, foam. Furthermore, some organic matter that cannot be decomposed settles, also generating a certain amount of foam.

[0003] In the related art, the patent document with application number: CN202321550904.2 discloses a foam expelling device for a sewage treatment tank, which is arranged in the sewage treatment tank and includes a fixed column arranged in the sewage treatment tank. The top of the fixed column is provided with a mounting platform. The mounting platform is provided with a plurality of nozzles arranged in a ring shape and directed outward to spray water outward from the middle of the sewage treatment tank to form a liquid level difference with the outer liquid surface. The utility model provides a plurality of nozzles in the sewage treatment tank that spray water outward. During the water spraying process, a liquid level difference is formed between the middle and the outer sides of the sewage treatment tank. The foam in the sewage treatment tank is collected at the edge with the flow of the liquid surface and then flows out to complete the foam elimination in the tank. When combined with the addition of a defoaming agent, the defoaming effect can be improved without the need for manual defoaming in the later stage. However, the device uses a nozzle to spray water, and the nozzle is tilted upward. It cannot effectively expel the foam below the nozzle and has a limited range. Therefore, we propose a foam expelling device for a sewage treatment tank.

The second connecting pipe 3 is provided at the central position of the upper end of the cross pipe. The upper end of the second connecting pipe 3 passes through the mounting plate 1. A plurality of groups of second nozzles 12 are symmetrically installed on the side of the second annular pipe 3. The second nozzle 12 is arranged horizontally. Water is sprayed outward through the inclined first nozzle 7 and the horizontally arranged second nozzle 12.

The foam in the sewage treatment is gathered to the edge with the flow of the liquid surface and then flows out to complete the elimination of the foam in the pool. In combination with the addition of a defoaming agent, the defoaming effect can be improved, and there is no need for manual cooperation in the later defoaming. In addition, the height of the nozzle can be adjusted to meet the defoaming requirements of different liquid level heights.

[0024] When the embodiments of the present invention are implemented, Figure 1 、 3 As shown, an electromagnetic stop valve 9 is installed on the second connecting pipe 3, one end of the first connecting pipe 4 and the second connecting pipe 3 is connected to the water inlet pipe 2, the first connecting pipe 4 and the second connecting pipe 3 are telescopic hoses, and a drive motor 15 is detachably installed on the upper end of the mounting plate 1, and a rotating shaft 16 is connected to the lower output end of the drive motor 15, and a gear 17 is fixedly installed on the lower end of the rotating shaft 16. The first connecting pipe 4 and the second connecting pipe 3 both adopt telescopic hoses to ensure the normal up and down movement of the first annular pipe 4 and the second annular pipe 3.

[0025] When the embodiments of the present invention are implemented, Figure 1 、 3As shown, the side of the gear 17 is engaged with the annular rack 18, and the annular rack 18 is fixedly installed on the side of the rotating sleeve 19. The rotating sleeve 19 and the annular rack 18 constitute a gear structure. The upper end of the rotating sleeve 19 is rotatably arranged inside the lower end of the mounting plate 1. The driving motor 15 rotates, which can rotate the gear 17, drive the rotating sleeve 19 engaged therewith to rotate, and then drive the driving plate 22 and the crushing net 24 on the side of the rotating sleeve 19 to rotate.

[0026] When the embodiments of the present invention are implemented, Figure 1 、 2 As shown, four groups of connecting blocks 20 are symmetrically and detachably installed on the side surface of the lower end of the rotating sleeve 19, and a mounting frame 21 is welded to the side of the connecting block 20 away from the rotating sleeve 19, wherein one end of two groups of mounting frames 21 is fixedly installed with a driving plate 22, and one end of the other two groups of mounting frames 21 is fixedly installed with a mounting frame 23, and a crushing net 24 is arranged inside the mounting frame 23. The lower end of the fixed sleeve 10 is integrally formed with a support rod 8, and the support rod 8 is vertically arranged. The first telescopic rod 5 and the second telescopic rod 11 are waterproof electric telescopic rods. The driving motor 15 rotates to drive the rotation of the driving plate 22, and then the driving plate 22 contacts the liquid surface in the pool to form waves or flow outward in the middle, driving the foam to move to the outside and then flow out. In the case of defoaming with the nozzle, the defoaming effect is improved. At the same time, the crushing net 24 can crush the foam during the rotation process, assist in defoaming, and improve the defoaming effect.

[0027] In this embodiment, all components are universal standard parts or components known to those skilled in the art. Their structures and connection principles are known to those skilled in the art through technical manuals or conventional experimental methods. When foam elimination is required, the electromagnetic shut-off valve 9 is first opened to allow clean water to flow in through the first connecting pipe 4 and the second connecting pipe 3. These connecting pipes are telescopic hoses, allowing the annular pipes to move up and down as needed; the first nozzle 7, which is set obliquely at the lower end of the first annular pipe 6, begins to spray water outward, and the second nozzle 12, which is set horizontally on the side of the second annular pipe 13, also begins to spray water outward. Due to the special arrangement of the nozzles (inclined and horizontal), a liquid level difference from the middle to the outside is formed in the sewage treatment tank during the water spraying process, causing the foam in the tank to move to the edge with the water flow; after the drive motor 15 is started, it drives the gear 17 to rotate through the rotating shaft 16. The gear 17 engages with the annular rack 18, causing the rotating sleeve 19 to rotate accordingly. A repelling plate 22 is mounted on the side of the rotating sleeve 19. During its rotation, the plate 22 contacts the liquid surface in the tank, generating waves or flow, further pushing the foam toward the pool edge. Also fixed to the rotating sleeve 19 is a mounting frame 23 with a crushing net 24. As the plate 22 pushes the foam, the crushing net 24 rotates with the rotating sleeve 19, breaking up the passing foam, accelerating its breakdown and improving defoaming efficiency. The foam pushed toward the edge eventually flows out of the wastewater treatment tank, completing the defoaming process. Throughout the operation, the first and second telescopic rods 5, 11 can adjust the height of the nozzle as needed to accommodate varying liquid levels and ensure optimal defoaming results. Defoaming agents can also be used during the spraying process to enhance the defoaming effect and effectively remove foam.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
