Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an air flotation machine for river treatment. Background Technology

[0002] A dissolved air flotation (DAF) system generates a large number of microbubbles in water, causing air to adhere to suspended particles in the form of highly dispersed microbubbles. These microbubbles create a density less than that of water, allowing the particles to float on the surface using buoyancy, thus achieving solid-liquid separation in water treatment. DAF systems are categorized into ultra-efficient shallow DAF systems, vortex DAF systems, and horizontal flow DAF systems. They are used in water supply, industrial wastewater, and municipal sewage treatment.

[0003] Existing dissolved air flotation (DAF) machines are mainly fixed in one place, and wastewater is pumped into the DAF machine for impurity treatment. It is impossible to move the DAF machine into the river to treat the flowing water in the river, resulting in poor flexibility in use.

[0025] like Figures 1-4As shown, this utility model provides an air flotation machine for river treatment, including a cleaning cylinder 3. The top of the cleaning cylinder 3 is connected to a slag scraping chamber 1. A floating mechanism is connected to the circumference of the cleaning cylinder 3. One end of the cleaning cylinder 3 is located above the bottom of the inner wall of the slag scraping chamber 1. A slag outlet is provided on the outer wall of the slag scraping chamber 1. The bottom of the cleaning cylinder 3 is connected to a sedimentation chamber 5 through a connecting rod 4. A sewage outlet 6 is provided on the sedimentation chamber 5. An air inflation mechanism and a slag scraping assembly are provided inside the slag scraping chamber 1. The air inflation mechanism is connected to the floating mechanism. A dissolved air tank is connected to the top of the slag scraping chamber 1. One end of the dissolved air tank is connected to a dissolved air pipe 7. The other end of the dissolved air pipe 7 extends into the cleaning cylinder 3 and is connected to a first aeration device.

[0026] In this embodiment, the dissolved gas pipeline 7 is also connected to multiple dissolved gas branch pipes. The end of each dissolved gas branch pipe that is away from the dissolved gas pipeline 7 extends into the impurity removal cylinder 3 and is connected to a second aeration device. Multiple second aeration devices can improve aeration efficiency and improve impurity removal effect.

[0027] In this embodiment, the inner wall of the impurity removal cylinder 3 is connected to one end of the mesh 8 by multiple fixed rods 14. The mesh 8 is a cylindrical structure. The end of the mesh 8 away from the fixed rods 14 extends into the sedimentation chamber 5 and connects to the inner wall of the sedimentation chamber 5. The mesh 8 is used to guide and settle large particles of river water in the impurity removal cylinder 3. Since the river water can enter the interior of the mesh 8 from the top, it will not block the large particles of sediment. It can guide the large particles of sediment in the dissolved air river water to fall into the sedimentation chamber 5 for sedimentation.

[0028] In this embodiment, the slag scraping assembly includes a transmission mechanism 10, a slag scraping plate 12, and a support rod 13. The transmission mechanism 10 is provided on both opposite sides of the inner wall of the slag scraping chamber 1. The two ends of the support rod 13 are respectively connected to the transmission mechanisms 10 on both sides. The slag scraping plate 12 is fixedly connected to the bottom end of the support rod 13. The slag scraping plate 12 can be moved back and forth by the transmission mechanism 10 to scrape slag, which facilitates the removal of floating slag in the water.

[0029] In this embodiment, the transmission mechanism 10 includes a support plate 10.5, a drive motor 10.1, a slider 10.2, a lead screw 10.3, and a fixing plate 10.4. The support plate 10.5 is fixed to the inner wall of the slag scraping chamber 1. The drive motor 10.1 and two fixing plates 10.4 are fixedly mounted on the support plate 10.5. The two fixing plates 10.4 are respectively located at both ends of the support plate 10.5. The output end of the drive motor 10.1 passes through the fixing plate 10.4 near the drive motor 10.1 and is connected to one end of the lead screw 10.3. The other end of the lead screw 10.3 passes through the slider 10.2 and is rotatably connected to the other fixing plate 10.4 on the support plate 10.5. The slider 10.2 is connected to one end of the support rod 13. The drive motor 10.1 can drive the lead screw 10.3 to rotate, causing the slider 10.2 to move along the lead screw 10.3. The movement of the slider 10.2 can drive the slag scraper 12 and the support rod 13 to move back and forth to scrape slag.

[0030] In this embodiment, the floating mechanism includes a floating chamber 2, the outer wall of which is provided with a plurality of water passage holes, an airbag 9 is provided inside the floating chamber 2, the airbag 9 is connected to an inflation mechanism, and an air release pipe is also connected to the airbag 9, which can release the airbag 9. An electric valve can also be provided on the air release pipe to realize remote operation of inflation and deflation of the airbag 9.

[0031] In this embodiment, the inflation mechanism includes an inflation box 11, inside which a blower 11.1 is fixedly connected. A vent hole 11.3 is provided at the top of the inflation box 11. One end of the blower 11.1 is connected to an inflation pipe 11.2, and the other end of the inflation pipe 11.2 extends into the floating chamber 2 and is connected to the airbag 9. The blower 11.1 can inflate the airbag 9 to make the air flotation machine float. In addition, the airbag 9 can be used to quickly change the water in the impurity removal cylinder 3 by allowing the air flotation machine to float and sink back and forth.

[0032] In this embodiment, the impurity removal cylinder 3 is a square cylinder.

[0033] Working principle: When in use, the air flotation machine is placed in the river water. The air bladder 9 of the air flotation machine is inflated by the blower 11.1. The air flotation machine is placed in the river water and then inflated, which will cause the river water to rise above the top of the screen 8 and then fall into the screen 8 to dissolve the air, thus purifying the river.

[0034] The dissolved air tank is started, and the dissolved air pipe 7 and the dissolved air branch pipe enter the first aeration device and the second aeration device for aeration. Since the first aeration device and the second aeration device are both located inside the mesh 8, the bubbles generated after aeration encapsulate small suspended particles and cause them to float to the surface. Large particles of sediment in the mesh 8 sink down along the mesh and accumulate in the sedimentation chamber 5. The large particles of sediment can be discharged through the drain outlet 6. The suspended particles float to the top of the impurity removal cylinder 3. The drive motor 10.1 is started. The drive motor 10.1 drives the slider 10.2 to move horizontally through the lead screw 10.3. The slider 10.2 on the transmission mechanism 10 on both sides of the scum scraping chamber 1 drives the support rod 13 and the scum scraper 12 to move back and forth to achieve scum scraping treatment on the water surface. The scum is scraped into the scum scraping chamber 1 by the scum scraper 12. Since the impurity removal cylinder 3 in the scum scraping chamber 1 is higher than the bottom of the inner wall of the scum scraping chamber 1, it can store the scum. After a certain period of use, the air flotation machine is retracted and the scum is discharged through the scum discharge port on the scum scraping chamber 1.
