Description

Technical Field

[0001] This utility model relates to the technical field of air flotation equipment for pollution control, and in particular to an air flotation equipment for pollution control that is easy to clean. 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. This creates a density less than that of water, allowing the particles to float on the surface using buoyancy, thus achieving solid-liquid separation. DAF systems are classified into ultra-efficient shallow DAF systems, vortex DAF systems, and horizontal flow DAF systems. Currently, they are used in water supply, industrial wastewater, and municipal sewage treatment. The advantages of DAF systems include low investment, small footprint, high degree of automation, and convenient operation and management. With the development of technology, DAF equipment for pollution control that is easy to clean has been greatly developed. This development has brought great convenience to the cleaning of DAF equipment, and its types and quantities are increasing daily.

[0003] During the operation of the flotation machine, the scum is pushed into the scum discharge tank by scrapers, and then discharged through the scum discharge pipe on the scum discharge tank. The scum after flotation usually contains a variety of components, such as grease, fine suspended particles, and microbial flocs. These substances have a certain degree of stickiness, which causes the scum to adhere to the inside of the scum discharge tank and cannot be discharged through the scum discharge pipe. If it is not cleaned for a long time, the continuous accumulation of scum will cause the adhesion layer to gradually thicken, which will reduce the volume of the scum discharge tank and require more frequent scum discharge operations, thereby increasing the workload of the staff. Based on the above problems, this application proposes a flotation device for pollution prevention that is easy to clean. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an easily cleanable air flotation device for pollution control, thereby solving the problems mentioned in the background section.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1-5A pollution control flotation device that is easy to clean includes a flotation tank 1. A effluent trough 26 is fixedly installed on the right side of the flotation tank 1, and the effluent trough 26 is connected to the flotation tank 1. A drain pipe 27 is fixedly installed on the right side of the effluent trough 26, and a control valve is fixedly installed on the surface of the drain pipe 27. A discharge trough 2 is fixedly installed on the right side of the flotation tank 1, and a slag discharge pipe 3 is fixedly installed on the front side of the discharge trough 2. A control valve is fixedly installed on the surface of the slag discharge pipe 3. A scraping assembly is installed on the surface of the discharge trough 2, and a moving assembly is installed on the surface of the flotation tank 1. The flotation tank 1 has a mounting plate 20 on its top via a movable component. An adjustable scum cleaning component is mounted on the side of the mounting plate 20. A water inlet pipe 28 and an air inlet pipe 29 are fixedly mounted on the left side of the flotation tank 1. The scraping component includes a U-shaped plate 4 fixedly mounted on the right side of the discharge trough 2. A drive motor 5 is fixedly mounted on the rear side of the U-shaped plate 4. A screw 6 is fixedly mounted on the output end of the drive motor 5. A threaded sleeve 7 is threaded onto the surface of the screw 6. A guide sleeve 8 is fixedly mounted at the bottom of the threaded sleeve 7. The guide sleeve 8 has a sliding mechanism inside. A guide rail 9 is provided, which is fixedly installed inside the U-shaped plate 4. A connecting column 10 is fixedly installed on the left side of the screw sleeve 7, and a scraper 11 is fixedly installed at the bottom of the connecting column 10. The scraper 11 is made of metal and contacts the inner wall of the discharge trough 2, making the scraper 11 more durable and less prone to deformation and bending. The scraper 11 is slidably installed inside the discharge trough 2. The drive motor 5 drives the output end to drive the screw 6 to rotate, so that the screw sleeve 7 drives the guide sleeve 8 to slide on the surface of the guide rail 9. The screw sleeve 7 drives the scraper 11 to move inside the discharge trough 2 through the connecting column 10. The scraper 11 pushes the scum attached to the inner wall of the discharge trough 2 to the scum discharge pipe 3 for discharge. This avoids the situation where the scum accumulates continuously due to lack of cleaning for a long time, causing the adhesion layer to gradually thicken. This avoids the situation where the volume of the scum discharge trough decreases due to the thickening of the adhesion layer, requiring more frequent scum discharge operations, thus avoiding the situation where frequent operations increase the workload of the staff.

[0017] Specifically, the moving assembly includes a rotary motor 12 and a fixed base 17 fixedly installed on the top of the flotation tank 1. A driving synchronous pulley 13 is fixedly installed at the output end of the rotary motor 12. A synchronous belt 14 is meshed inside the driving synchronous pulley 13, and a driven synchronous pulley 15 is meshed inside the synchronous belt 14. A mounting shaft 18 is mounted inside the fixed base 17 via bearings. Four sprockets 19 are fixedly installed on the surface of the mounting shaft 18, and a transmission chain 16 meshes between the surfaces of two sprockets 19. The driven synchronous pulley 15 is fixedly installed on the left side of the mounting shaft 1. At the front end of 8, the adjustable scum cleaning component includes a connecting plate 21 overlapping and disposed on the side of the mounting plate 20. An adjusting groove 22 is provided through the surface of the connecting plate 21. A fixing column 23 is overlapping and disposed inside the adjusting groove 22. The fixing column 23 is fixedly installed on the side of the mounting plate 20. A fixing nut 24 is threaded on the surface of the fixing column 23. A scraper 25 is fixedly disposed at the bottom of the connecting plate 21. There are several scrapers 25, and the scrapers 25 are symmetrically distributed. Wastewater is transported to the interior of the flotation tank 1 through the air inlet pipe 29, and the water inlet pipe 28 is connected to the dissolved air tank. The dissolved air tank supplies dissolved air water into the flotation tank 1 through the air inlet pipe 29, causing air to adhere to the suspended particles in the form of highly dispersed microbubbles. The suspended particles float to the surface, and the output end of the rotary motor 12 drives the active synchronous pulley 13 to rotate. The active synchronous pulley 13 drives the driven synchronous pulley 15 to rotate through the synchronous belt 14, and the driven synchronous pulley 15 drives the left mounting shaft 18 to rotate. This causes the mounting shaft 18 to drive the left sprocket 19 to rotate. The left sprocket 19 drives the right sprocket 19 to rotate through the transmission chain 16, which in turn drives the right sprocket 19 to rotate through the mounting shaft 18. The moving chain 16 drives the mounting plate 20 to move. The mounting plate 20 drives the connecting plate 21 to move through the fixing column 23 and the fixing nut 24. This causes the connecting plate 21 to drive the scraper 25 to push the scum to the right, allowing the scum to enter the discharge tank 2. When the height of the scraper 25 needs to be adjusted, the fixing nut 24 is rotated, and the scraper 25 is moved through the connecting plate 21. When the scraper 25 moves to the appropriate height, the fixing nut 24 is tightened on the surface of the fixing column 23. This allows the scraper 25 and the connecting plate 21 to be used for scum of different thicknesses.

[0018] The pollution control system uses an easy-to-clean flotation device connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0019] In use: When it is necessary to discharge the scum in the discharge tank 2, open the control valve on the scum discharge pipe 3 to allow the scum to be discharged through the scum discharge pipe 3. At the same time, the drive motor 5 drives the output end to drive the screw 6 to rotate, so that the screw sleeve 7 drives the guide sleeve 8 to slide on the surface of the guide rail 9. The screw sleeve 7 drives the scraper 11 to move inside the discharge tank 2 through the connecting column 10. The scraper 11 pushes the scum attached to the inner wall of the discharge tank 2 to the scum discharge pipe 3 for discharge. The water with the scum removed enters the water outlet tank 26 and is discharged through the drain pipe 27.
