Description

Technical Field

[0001] This utility model relates to the field of air flotation machines, and in particular to a high-efficiency micro-power micron air flotation machine. Background Technology

[0002] An air flotation machine is a water treatment device that uses a dissolved air system to generate a large number of microbubbles in water. This causes air to adhere to suspended particles in the form of highly dispersed microbubbles, resulting in a density less than that of water. By utilizing the principle of buoyancy, the particles float on the water surface, thus achieving solid-liquid separation.

[0003] An air flotation machine is a device used in water treatment processes, primarily to remove suspended solids, grease, and other fine particulate matter from water. It generates microbubbles, causing these contaminants to adhere to the bubbles. These contaminants then rise to the surface with the bubbles, forming scum, which is then removed by a scraper, thus purifying the water.

[0004] Existing air flotation machines use air bubbles to move waste residue to the surface of wastewater. However, when pollutant concentrations are high, particulate matter has large density differences, and suspended solids concentrations are high, simply introducing air bubbles once can easily lead to poor waste residue removal and ineffective wastewater treatment.

[0005] Therefore, it is necessary to provide a new, high-efficiency micro-powered micron air flotation machine to solve the above-mentioned technical problems. Utility Model Content

A flow guide platform is fixedly installed on the bottom wall of the air flotation box at the second region, the third region, and the fourth region. The front view cross section of the flow guide platform is triangular. Mounting frames are fixedly installed on the inclined surfaces of the flow guide platforms in the second region and the third region. Micron aerators are fixedly installed on the two mounting frames.

[0008] Preferably, the bottom wall of the air flotation box is equipped with sludge discharge ports at the locations of the first, second, third, fourth, and fifth regions, and the middle three sludge discharge ports are staggered with the three guide platforms.

[0009] Preferably, the air flotation box is equipped with an inlet at one end and an outlet at the other end.

[0010] Preferably, a slag scraping device is installed on the top of the flotation box above the second, third, and fourth regions. A slag discharge trough is fixed inside the flotation box. The bottom of the slag discharge trough has a U-shaped structure. One end of the slag discharge trough is inclined and fixedly connected to the top of the third partition plate. A slag discharge port is installed in the flotation box at the position corresponding to the slag discharge trough.

[0011] Preferably, the slag scraping device includes a motor, two rotating rods, two first chains, and multiple scraper blades. Both rotating rods are rotatably connected to the flotation box, and sprockets are fixed at both ends of the two rotating rods. The first chains are movably connected to the two sprockets on the same side of the two rotating rods and are fixedly connected to the two first chains. The motor is fixed to the flotation box, and the output end of the motor is fixedly connected to one of the rotating rods.

[0012] Preferably, liquid inlet devices are installed on both sides of the flotation tank near the first region. Each liquid inlet device includes a storage tank, a pneumatic dosing pump, and a drain pipe. The storage tank is fixedly installed on the side wall of the flotation tank, and a perforated aerator is installed inside the storage tank. The pneumatic dosing pump is installed on the storage tank, with its input end connected to the inner cavity of the storage tank and its output end connected to the drain pipe.

[0013] Preferably, the top of the air flotation box is also fixed with a support frame, and two rotating devices are fixed on the support frame. The two drain pipes can respectively introduce liquid into the two rotating devices. The support frame is also equipped with a transmission device for driving the two rotating devices to rotate.

[0014] Preferably, the rotating device includes a main pipe closed at the bottom and multiple branch pipes. The main pipe is rotatably connected to the support frame and rotatably connected to the drain pipe. The top ends of the multiple branch pipes are all fixedly connected to the main pipe.

[0015] Preferably, the transmission device includes a drive wheel, a driven wheel, a second chain, a first support rod, and a second support rod. The drive wheel is fixedly sleeved on one of the rotating rods. The first support rod is rotatably connected to the support frame. The driven wheel is fixed to the first support rod.

[0016] Compared with related technologies, the high-efficiency micro-power micron air flotation machine provided by this utility model has the following beneficial effects:

[0017] 1. The motor drives the rotating rod to rotate. Under the action of the first chain, the other rotating rod rotates. Through the rotation of the two first chains, multiple scrapers rotate. When the rotating rod rotates, the drive wheel on the rotating rod rotates. Under the action of the second chain, the driven wheel drives the first support rod to rotate, thereby causing the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate, which in turn causes the third bevel gear to rotate. The third bevel gear drives the second support rod to rotate, and the second support rod drives the fourth bevel gear to rotate, which in turn causes the fifth bevel gear to rotate. Under the action of the second and fourth bevel gears, the two main pipes rotate. The flocculant and coagulant aid enter the main pipe through the drain pipe and are then transported to the flotation tank through various branch pipes. The rotating branch pipes can make the discharged liquid more evenly dispersed, and the continuous rotation of the branch pipes in the wastewater can effectively mix the added flocculant and coagulant aid with the wastewater, making it more efficient and improving the flocculation effect of impurities in the wastewater.

[0018] 2. Wastewater is introduced into the first zone through the inlet and mixed with the added flocculant and coagulant aid under the action of the air agitator. The waste residue is discharged through the sludge discharge port in the first zone. The wastewater enters the second zone under the action of the guide platform and is mixed evenly with the micron-sized bubbles sprayed from the micron aerator. The lighter scum flows to the third zone, while the heavier particles are periodically discharged through the slag discharge port under the action of the guide platform. The wastewater that has undergone the preliminary air flotation reaction enters the deep air flotation zone in sequence for further reaction. Smaller bubbles separate the remaining scum and particles. The scum is scraped into the slag discharge trough by the continuous skimming action of the scraper and continuously discharged through the slag discharge port. The clear water from the fourth and fifth zones is discharged from the outlet. This application improves the wastewater treatment effect through multiple aeration processes.

[0019] 3. This application uses only one motor. In special areas with high requirements for explosion-proof mechanical and electrical equipment, inconvenient installation of mechanical and electrical equipment, corrosive environments, etc., such as mining environments, this application mostly adopts pneumatic form to improve safety.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1-3 ,in, Figure 1 A schematic diagram of the structure of the high-efficiency micro-power micron air flotation machine provided by this utility model; Figure 2 for Figure 1 A cross-sectional structural diagram of the structure shown; Figure 3 for Figure 1 A partial structural diagram of the structure shown.

[0026] In the specific implementation process, such as Figures 1-3As shown, the system includes an air flotation box 1. The inner side of the air flotation box 1 is fixedly connected to a vertically arranged first partition plate 2, an inclined second partition plate 3, an inclined third partition plate 4, and a vertically arranged fourth partition plate 5. These partition plates divide the air flotation box 1 into five interconnected regions: a first region 6, a second region 7, a third region 8, a fourth region 9, and a fifth region 10. A fixing frame 11 is fixed to the bottom wall of the air flotation box 1 at the location of the first region 6. An air agitator 12 (model JA-200) is fixedly installed on the fixing frame 11, generating bubbles with a diameter of 1-3 mm. A flow guide platform 13 is fixed to the bottom wall of the air flotation box 1 at the locations of the second region 7, the third region 8, and the fourth region 9. The frontal cross-section of the flow guide platform 13 is triangular. The second region 7 and the... Mounting brackets 14 are fixed on the inclined surfaces of the guide platform 13 in the third zone 8. Both the fixing brackets 11 and the mounting brackets 14 are secured with rigid and flexible materials to reduce vibration. Micron-sized aerators 15 are fixedly mounted on both mounting brackets 14. This application can also install an air filter at one end of the flotation box 1, with an on-site air source (greater than 0.5 MPa). The on-site air source is purified by the air filter and then supplies air to the air mixer 12 and micron-sized aerators 15. The air mixer 12 continuously provides air mixing to the first zone 6, and the micron-sized aerators 15 continuously provide micron-sized bubbles to the second zone 7 and the third zone 8. The two micron-sized aerators 15 use FB-150 model 10-20µm diameter bubbles for initial air flotation separation, and then use NBG-05 model 1-5µm diameter bubbles for deep air flotation separation.

[0027] The bottom wall of the air flotation tank 1 is equipped with sludge discharge ports 16 at the positions of the first region 6, the second region 7, the third region 8, the fourth region 9 and the fifth region 10. The three middle sludge discharge ports 16 are staggered with the three guide platforms 13. One end of the air flotation tank 1 is equipped with a water inlet 17 and the other end of the air flotation tank 1 is equipped with a water outlet 18.

One end of the slag discharge trough 19 is inclined and fixedly connected to the top of the third partition plate 4. A slag discharge port 20 is installed in the flotation box 1 at the position corresponding to the slag discharge trough 19. Waste slag is discharged from the flotation box 1 through the slag discharge port 20.

[0029] The slag scraping device includes a motor 21, two rotating rods 22, two first chains 23, and multiple scraper blades 24. The two rotating rods 22 are rotatably connected to the flotation box 1. Both ends of the two rotating rods 22 are fixed with sprockets 25. The first chains 23 are movably connected to the two sprockets 25 on the same side of the two rotating rods 22. The motor 21 is fixed to the flotation box 1. The output end of the motor 21 is fixedly connected to one of the rotating rods 22. The rotating rod 22 is driven to rotate by the motor 21. The rotation of the two first chains 23 causes the multiple scraper blades to rotate. The continuously rotating scraper blades push the waste slag to the waste slag trough.

[0030] Liquid inlet devices are installed on both sides of the flotation tank 1 near the first area 6. Each liquid inlet device includes a storage tank 26, a pneumatic dosing pump 27, and a drain pipe 28. The storage tank 26 is fixedly installed on the side wall of the flotation tank 1. A perforated aerator is installed inside the storage tank 26. The pneumatic dosing pump 27 is installed on the storage tank 26. The input end of the pneumatic dosing pump 27 is connected to the inner cavity of the storage tank 26, and the output end of the pneumatic dosing pump 27 is connected to the drain pipe 28. Aeration and stirring are performed through the perforated aerator, with bubbles about 5 mm in diameter, to dissolve the powder in clean water for drug dissolution.

[0031] The top of the air flotation box 1 is also fixed with a support frame 29, and two rotating devices are fixed on the support frame 29. The two drain pipes 28 can respectively introduce liquid into the two rotating devices. The support frame 29 is also equipped with a transmission device, which is used to drive the two rotating devices to rotate.

[0032] The rotating device includes a main pipe 30 with its bottom closed and multiple branch pipes 31. The main pipe 30 is rotatably connected to the support frame 29 and is rotatably connected to the drain pipe 28. The top ends of the multiple branch pipes 31 are all fixedly connected to the main pipe 30.

[0033] The transmission device includes a drive wheel 32, a driven wheel 33, a second chain 34, a first support rod 35, and a second support rod 36. The drive wheel 32 is fixedly sleeved on one of the rotating rods 22. The first support rod 35 is rotatably connected to the support frame 29. The driven wheel 33 is fixed to the first support rod 35. The second chain 34 is movably connected to the driven wheel 33 and the drive wheel 32. A first bevel gear 37 is fixed at the end of the first support rod 35 away from the driven wheel 33. The second support rod 36 is rotatably connected to the support frame 29. A third bevel gear 39 and a fourth bevel gear 40 are fixed at both ends of the second support rod 36, respectively. A second bevel gear 38 is fixed on the main pipe 30 near the first bevel gear 37, and a fifth bevel gear 41 is fixed on the main pipe 30 away from the first bevel gear 37. The second bevel gear 38 meshes with the first bevel gear 37 and the third bevel gear 39, and the fifth bevel gear 41 meshes with the fourth bevel gear 40.

[0034] The working principle of this utility model is as follows: The motor 21 drives the rotating rod 22 to rotate. Under the action of the first chain 23, the other rotating rod 22 rotates. Through the rotation of the two first chains 23, multiple scrapers rotate. When the rotating rod 22 rotates, the drive wheel 32 on the rotating rod 22 rotates. Under the action of the second chain, the driven wheel 33 drives the first support rod 35 to rotate, thereby causing the first bevel gear 37 to rotate. The first bevel gear 37 drives the second bevel gear 38 to rotate, which in turn causes the third bevel gear 39 to rotate. The rotation of the third bevel gear 39 drives the second support rod 36 to rotate, which in turn drives the fourth bevel gear 40 to rotate, causing the fifth bevel gear 41 to rotate. Under the action of the second bevel gear 38 and the fourth bevel gear 40, the two main pipes 30 rotate. Each of the two liquid storage tanks 26 is equipped with an inlet (not shown in the figure). Flocculant and coagulant aid are added to the two liquid storage tanks 26 respectively. The flocculant and coagulant aid are pumped to the two drain pipes 28 by the pneumatic dosing pump 27, and the liquid enters the main pipe 30 through the drain pipes 28. The wastewater is transported to the flotation tank 1 through various branch pipes 31. The rotating branch pipes 31 allow for more uniform dispersion of the discharged liquid. The continuous rotation of the branch pipes 31 within the wastewater effectively mixes the added flocculant and coagulant aid with the wastewater, improving the flocculation effect of impurities in the wastewater. The wastewater is then introduced into the first zone 6 through the inlet 17, where it mixes with the added flocculant and coagulant aid under the action of the air agitator 12. Waste residue is discharged through the sludge discharge port 16 in the first zone 6, and the wastewater enters the second zone 6 under the action of the guide platform 13. In zone 7, the micron-sized bubbles sprayed from the micron aerator 15 are mixed evenly. The lighter scum flows to the third zone 8, while the heavier particles are periodically discharged from the scum outlet 20 under the action of the guide platform 13. The wastewater that has undergone the initial air flotation reaction enters the deep air flotation zone in sequence for further reaction. Smaller bubbles separate the remaining scum and particles. The scum is scraped into the scum discharge tank 19 by the continuous skimming action of the scraper and continuously discharged through the scum outlet 20. The clear water in the fourth zone 9 and the fifth zone 10 is discharged from the outlet 18.

[0035] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
