Description

Technical Field

[0001] This utility model relates to the field of air flotation devices, and in particular to an air flotation device with a quick-change dissolved gas release device. Background Technology

[0002] An air flotation (AF) unit is a highly efficient water treatment device primarily used to remove small suspended solids, colloidal particles, grease, and emulsified oils that are difficult to settle in water, achieving solid-liquid or liquid-liquid separation. The principle of an AF unit is as follows: highly dispersed microbubbles are introduced into the water. As these bubbles rise, they adhere to suspended pollutants or grease in the wastewater, forming a flotation mass with a density less than water. Due to the buoyancy of the bubbles, these flotation masses rise to the surface, forming a scum layer. Subsequently, a scum scraper removes this scum layer from the surface, thus achieving solid-liquid or liquid-liquid separation.

[0003] In existing dissolved air flotation (DAF) devices, the dissolved air release device is a crucial component, installed at the end of the pipeline via a threaded connection to achieve dissolved air release. However, in DAF devices, the dissolved air release device is typically located internally at a lower position, and the fixed pipeline installation makes disassembly inconvenient. This necessitates entering the device for disassembly, which requires draining wastewater from the system, making disassembly extremely difficult and hindering rapid replacement. Furthermore, the angle of the dissolved air release device cannot be adjusted after installation, resulting in poor flexibility and adaptability in its use. Utility Model Content

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, a flotation device for quick replacement of dissolved gas release device includes a main body 1. The interior of the main body 1 is divided into an inlet chamber 2, a separation chamber 3, a slag collection tank 4, and a discharge chamber 5 by a partition. A dissolved gas pump 6 and a dissolved gas tank 7 are installed on the outer wall of the main body 1. A conveying pipe 8 is connected to the dissolved gas tank 7, and a dissolved gas release structure 9 is connected to the conveying pipe 8. The dissolved gas release structure 9 is located in the separation chamber 3. A slag scraping structure 10 is installed on the main body 1. The partition between the inlet chamber 2 and the separation chamber 3 has a through hole, and the main body 1 has a water inlet pipe communicating with the inlet chamber 2. The dissolved gas pump 6 has a return pipe 11, which is connected to the discharge chamber 5. A dissolved gas pipe 12 is provided between the dissolved gas pump 6 and the dissolved gas tank 7. The main body 1 has a drain pipe 13 communicating with the discharge chamber 5.

[0020] The slag scraping structure 10 includes a bracket, a sprocket, a chain, a scraper, and a drive motor. The sprocket is mounted on the upper end of the device body 1 via the bracket. The chain and the scraper are connected and the chain is sleeved on the sprocket. The drive motor is fixed on the device body 1 and is connected to the sprocket.

[0021] When using an air flotation device for wastewater treatment, wastewater flows into the inlet chamber 2 inside the main body 1 of the device through the inlet pipe, and then enters the separation chamber 3 through the through hole. Some water enters the discharge chamber 5, and then enters the dissolved air pump 6 through the return pipe 11. The dissolved air pump 6 transports the water to the dissolved air tank 7 through the dissolved air pipe 12 to form mixed dissolved air water. The dissolved air water then enters the dissolved air release structure 9 through the delivery pipe 8, and is finally released from the end of the dissolved air release structure 9. The density of the released dissolved air water is less than that of the wastewater, forming countless tiny bubbles. The bubbles float to the surface. During this process, suspended solids in the wastewater adhere to the bubbles and rise together, thus forming a layer of scum on the water surface, thereby achieving solid-liquid separation of the wastewater. The scum floats on the water surface. At this time, the drive motor in the scum scraping structure 10 runs and drives the sprocket on the support to rotate. The sprocket drives the chain and scraper to move. The scraper is used to scrape the scum on the water surface. The scum enters the scum collection tank 4 for collection and is finally discharged from the scum discharge port of the scum collection tank 4. The separated water is discharged through the drain pipe 13 at the discharge chamber 5.

[0022] When needed, the dissolved gas release structure 9 can be quickly disassembled from the end of the delivery pipe 8, making it easy to replace the dissolved gas release part in the dissolved gas release structure 9. The angle of the dissolved gas release part can also be adjusted to improve the flexibility and adaptability of use.

[0023] According to the above implementation scheme, the dissolved gas release structure 9 includes a mounting flange 901, a fixed pipe 902, a connecting pipe 903, a rotary adjustment component 904, a releaser body 905, a release pipe 906, and a connector 907. The mounting flange 901 is fixedly connected to the fixed pipe 902. The connecting pipe 903 is rotatably connected to the lower end of the fixed pipe 902 through the rotary adjustment component 904. The releaser body 905 is fixedly connected to the release pipe 906. The connector 907 is located at the lower end of the connecting pipe 903 and is threadedly connected to the releaser body 905.

[0024] When installing the dissolved gas release structure 9, installation is completed via the mounting flange 901. The upper end of the connecting pipe 903 is mounted on the fixed pipe 902 via the rotary adjustment component 904, and the lower end is mounted on the releaser body 905 via the connector 907. The rotary adjustment component 904 is adjusted according to the actual situation to change the angle of the connecting pipe 903 so that the angle of the releaser body 905 is appropriate. During use, dissolved gas water enters the releaser body 905 through the fixed pipe 902, the conveying part in the rotary adjustment component 904, and the connecting pipe 903, and finally flows out smoothly from the release pipe 906. The flowing dissolved gas water generates numerous bubbles that carry suspended matter upwards, thereby achieving the purpose of solid-liquid separation. When it is necessary to replace the releaser body 905, the mounting flange 901 is removed to take off the entire dissolved gas release structure 9, and then the releaser body 905 is disassembled for replacement. The structure is simple and the performance is excellent.

[0025] The rotary adjustment assembly 904 includes a first connecting frame 9041, a second connecting frame 9042, an arc-shaped hole 9043, a pin 9044, a screw 9045, a locking block 9046, a bellows 9047, and a connecting flange 9048. The first connecting frame 9041 and the second connecting frame 9042 are respectively mounted on the fixed pipe 902 and the connecting pipe 903. The arc-shaped hole 9043 is opened on the second connecting frame 9042. The pin 9044 is fixedly connected to the first connecting frame 9041 and rotatably connected to the second connecting frame 9042. The screw 9045 is fixed on the first connecting frame 9041 and is located in the arc-shaped hole 9043. The locking block 9046 is connected to the screw 9045. The bellows 9047 is fixedly connected to the connecting flange 9048. The two connecting flanges 9048 are respectively connected to the fixed pipe 902 and the connecting pipe 903.

[0026] When adjusting the angle of the connecting pipe 903, after loosening the locking block 9046 on the screw 9045, the second connecting bracket 9042 rotates on the first connecting bracket 9041 via the pin 9044, thereby changing the angle of the connecting pipe 903 and the release body 905. During this process, the screw 9045 moves in the arc-shaped hole 9043, and the bellows 9047 between the connecting flanges 9048 bends, which does not affect the normal rotation. After the rotation adjustment is completed, the locking block 9046 is rotated to press on the second connecting bracket 9042, completing the fixed connection between the first connecting bracket 9041 and the second connecting bracket 9042, and then it can be used. During use, dissolved air water is transported normally through the bellows 9047 without affecting the normal release of dissolved air, and it will not affect the rotation adjustment.

[0027] It should be noted that, through the dissolved gas release structure 9, the releaser body 905 is installed at the lower end of the connecting pipe 903. The connecting pipe 903 is connected to the fixed pipe 902 through the rotary adjustment component 904. A mounting flange 901 is provided at the upper end of the fixed pipe 902, which allows the pipe on which the dissolved gas releaser is installed to be quickly disassembled without entering the separation chamber 3, facilitating the replacement work. The angle of the connecting pipe 903 and the releaser body 905 can be adjusted using the rotary adjustment component 904, so that the release pipe 906 is set at a suitable angle, ensuring the flexibility and adaptability of use. The first connecting frame 9041 and the second connecting frame 9042 are used for rotational adjustment, in conjunction with the corrugated pipe 9047. After the angle is adjusted, the normal delivery of dissolved gas water is not affected.

[0028] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
