DETAILED DESCRIPTION

[0028] In order for the person skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0029] As Figure 1 and Figure 2As shown, the utility model discloses a spraying device installation, including first spraying pipe 1, first spraying pipe 1 is set up with several first through -hole 101, first spraying pipe 1 is connected on the inlet pipe on waste water treatment pond. When using, water is sprayed from first through -hole 101, and the foam in waste water treatment pond is eliminated.

[0030] In order to be able to adjust the size of the water column that is sprayed in first through -hole 101, as Figures 2 to 6 As shown, the first spraying pipe 1 is rotatably connected with a spraying assembly, a plurality of spray openings are formed in the spraying assembly, the inner diameters of the plurality of spray openings are different, and the spray openings are on the same horizontal line with the first through -hole 101. By rotating the spraying assembly, the spray openings on the spraying assembly are aligned with the first through -hole 101, and the water in the first spraying pipe 1 flows into the spray openings from the first through -hole 101, and the water flowing out of the spray openings can eliminate the foam in the waste water treatment pond.

[0031] Specifically, the spraying assembly includes a second spraying pipe 2, the second spraying pipe 2 is sleeved on the first spraying pipe 1, the upper end face of the second spraying pipe 2 is integrally formed with a sealing ring 23, the outer wall of the first spraying pipe 1 is integrally formed with a fixing ring 11, the fixing ring 11 is formed with a rotating groove 111 matched with the sealing ring 23, and the sealing ring 23 is rotatably connected in the rotating groove 111. The spray opening includes a second through -hole 201 and a third through -hole 202, and the second through -hole 201 and the third through -hole 202 penetrate the side wall of the second spraying pipe 2. The diameter of the second through -hole 201 is the same as that of the first through -hole 101, and the diameter of the third through -hole 202 is smaller than that of the first through -hole 101.

[0032] When the sewage is initially treated, the impurity concentration in the water is relatively low, and at this time, the foam generated in the sewage can be easily eliminated. By rotating the second spraying pipe 2, the third through -hole 202 is aligned with the first through -hole 101, and since the diameter of the third through -hole 202 is smaller than that of the first through -hole 101, the water flowing out of the third through -hole 202 can increase the pressure of the water flow, the sprayed water column becomes thinner, can be sprayed farther, covers a wider area, and increases the ability of the spraying device to eliminate foam.

[0033] Further, if the foam in the waste water treatment pond is relatively viscous, and the finer water column cannot be eliminated, the second spraying pipe 2 is rotated again, so that the second through -hole 201 is aligned with the first through -hole 101, so that the sprayed water column can be thickened, and the relatively viscous foam in the waste water treatment pond can be eliminated.

[0034] It is worth noting that after long-term use, scale will be formed in the water inlet pipe, which will cause the water quality flowing through the first spray pipe 1 to be poor. Since the third through hole 202 has a small aperture, large particles of scale in the water can block the third through hole 202. When the third through hole 202 is blocked by large particles of scale, the inner wall of the first spray pipe 1 rubs against the inner wall of the second spray pipe 2 when the second spray pipe 2 is rotated multiple times, which can grind the large particles of scale blocking the third through hole 202. When the third through hole 202 is aligned with the first through hole 101 again, the pressure of the water can flush out the residual scale in the third through hole 202, preventing the third through hole 202 from being blocked by scale.

[0035] In order to quickly align the second through hole 201 and the third through hole 202 with the first through hole 101, as shown in Figures 4 to 7 The second spray pipe 2 is fixedly connected to the end face away from the sealing ring 23, and the second spray pipe 2 is integrally formed with a first limiting block 21 and a second limiting block 22 on the outer wall.

[0036] Specifically, when the side wall of the first limiting block 21 is in contact with the side wall of the third limiting block 31 during rotation of the second spray pipe 2, the second through hole 201 is concentric with the first through hole 101, and the third through hole 202 is blocked by the outer wall of the first spray pipe 1, so that the water in the first spray pipe 1 can be sprayed out of the second through hole 201. When the side wall of the second limiting block 22 is in contact with the side wall of the fourth limiting block 32, the third through hole 202 is concentric with the first through hole 101, and the second through hole 201 is blocked by the outer wall of the first spray pipe 1, so that the water in the first spray pipe 1 can be sprayed out of the third through hole 202.

[0037] Preferably, the third limiting block 31 and the fourth limiting block 32 are made of magnetic material and can attract the first limiting block 21 and the fourth limiting block 32, respectively, to prevent vibration during operation, which can cause misalignment of the second through hole 201 or the third through hole 202 with the first through hole 101, resulting in failure of water to be sprayed.

[0038] Further, a fourth through hole 301 is formed in the lower panel of the spray head 3, and water can also be sprayed downward from the fourth through hole 301 to eliminate foam directly below the spray head 3. Meanwhile, a scraper 12 is integrally formed on the inner wall of the first spray pipe 1 and is in contact with the lower panel of the spray head 3. When the second spray pipe 2 is rotated, the spray head 3 rotates with the second spray pipe 2, and the scraper 12 can scrape the large particles of scale blocking the fourth through hole 301 on the lower panel of the spray head 3, preventing the fourth through hole 301 from being blocked.

[0039] Because the water level in the wastewater treatment tank changes frequently, when the water level is high, the distance between the second spray pipe 2 and the water surface is close, resulting in a smaller spray area and reduced efficiency in eliminating foam. When the water level is low, the spray area becomes too large, and the sprayed water column is too dispersed to effectively eliminate foam.

[0040] To solve the above problems, such as... Figures 1 to 3 As shown, an adjusting pipe 5 is slidably connected to the first spray pipe 1. Adjusting components are installed on both the first spray pipe 1 and the adjusting pipe 5. These adjusting components are used to adjust the position of the first spray pipe 1 within the adjusting pipe 5.

[0041] Specifically, the adjusting assembly includes a connecting plate 4 and a hollow column 7. One end of the connecting plate 4 is welded to the outer wall of the fixing ring 11. Multiple first wedge plates 41 are integrally formed on the connecting plate 4, and a fifth limiting block 42 is welded to the upper end surface of the first wedge plates 41. The hollow column 7 is welded to the outer wall of the adjusting tube 5. A sliding column 72 is slidably connected inside the hollow column 7. A second wedge plate 721 that matches the first wedge plates 41 is integrally formed on the sliding column 72. A spring 71 is provided inside the hollow column 7. One end of the spring 71 is welded to the sliding column 72, and the end of the spring 71 away from the sliding column 72 is welded to the outer wall of the adjusting tube 5.

[0042] Specifically, by pulling the fifth limiting block 42 upwards, when the upper end face of the first wedge plate 41 is in contact with the lower end face of the second wedge plate 721, the second wedge plate 721 will compress the spring 71 towards the adjusting pipe 5. When the first wedge plate 41 moves away from the second wedge plate 721, the spring 71 will pop out the sliding column 72, causing the upper end face of the second wedge plate 721 to be in contact with the lower end face of the first wedge plate 41. This allows the position of the first spray pipe 1 in the adjusting pipe 5 to be adjusted, changing the distance between the first spray pipe 1 and the water surface, thereby controlling the size of the spray area.

[0043] Furthermore, a thrust plate 7211 is integrally formed on the second wedge plate 721. When it is necessary to lower the height of the first spray pipe 1 above the water surface, the thrust plate 7211 is pushed towards the regulating pipe 5, causing the second wedge plate 721 to move away from the first wedge plate 41, so that the fifth limiting block 42 falls on the valve 6, thereby lowering the first spray pipe 1. At the same time, the fifth limiting block 42 can also prevent the first spray pipe 1 from sliding out of the regulating pipe 5, thus protecting the first spray pipe 1 at its lowest position within the regulating pipe 5.

[0044] Furthermore, a valve 6 is installed on the regulating pipe 5, which can adjust the water pressure in the first spray pipe 1 by controlling the opening degree of the valve 6.

[0045] When the foam in the wastewater treatment tank is thick, the second spraying pipe 2 is rotated, the first limiting block 21 is attached to the third limiting block 31, the second through hole 201 is coincided with the first through hole 101, and the water column is large, so that the thick foam can be eliminated.

[0046] When the foam in the wastewater treatment tank is ordinary, the second spraying pipe 2 is rotated, the second limiting block 22 is attached to the fourth limiting block 32, the third through hole 202 is coincided with the first through hole 101, the water column is thin, the diffusion area is large, and the foam elimination efficiency is improved.

[0047] When the water level in the wastewater treatment tank changes, the connecting plate 4 is pulled, the position of the first spraying pipe 1 in the adjusting pipe 5 is adjusted, and the coverage area of the water column can be changed.

[0048] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application.
