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.
[0017] Please see Figure 1 , Figure 4 and Figure 5 A flotation machine for recycling waste aluminum alloy includes a body 1. An inner cylinder 2 for holding waste aluminum alloy is movably installed inside the body 1. Several nozzles 3 are evenly distributed above the inner cylinder 2 at the upper end of the body 1. A water pump 4 located on the left side of the body 1 is fixedly connected to the upper end of each nozzle 3 via a pipe. The water pump 4 allows for the recycling of the flotation solution from the waste aluminum alloy within the body 1. A turntable 5 is rotatably connected to the middle of the lower end of the inner cylinder 2. A brush plate 7 located inside the inner cylinder 2 is detachably connected to the upper end of the turntable 5 via a spring clip 6. By changing the connection between the spring clip 6 and the brush plate 7 or the turntable 5, the brush plate 7 can not only be mounted on the turntable 5, but also moved from the turntable 5. The disassembly of the turntable 5 facilitates the replacement of worn brush plates 7. The lower end of the turntable 5 is movably connected to the drive motor 8 located below the machine body 1, and the upper end of the drive motor 8 is fixedly connected to the bottom surface of the machine body 1. The drive motor 8 drives the brush plates 7 to rotate in the inner cylinder 2 through the connection of the turntable 5, so that the waste aluminum alloy can move in the inner cylinder 2, and fully contact the waste aluminum alloy with the flotation liquid, thereby improving the flotation effect of the waste aluminum alloy. An overflow outlet 10 is fixedly installed on the upper right side of the machine body 1. A scraper 9 is set above the connection between the overflow outlet 10 and the machine body 1. The rotation of the scraper 9 can scrape the light impurities floating on the surface of the flotation liquid to the overflow outlet 10.
[0018] A drain pipe 11 is fixedly installed at the lower end of the machine body 1, located behind the drive motor 8. The drain pipe 11 facilitates the discharge of flotation liquid from the machine body 1. Support plates 12, located on the outer side of the inner cylinder 2, are fixedly installed on the front and rear sides of the inner wall of the machine body 1, respectively. A pressure plate 13 is movably connected above the support plate 12. The installation of the pressure plate 13 can fix the inner cylinder 2 on the support plate 12. An electric push rod 14 is fixedly installed on the outer side of the pressure plate 13. The outer wall of the inner end of the electric push rod 14 is fixedly sleeved with the inner wall of the machine body 1, and the inner end of the output shaft of the electric push rod 14 is fixedly connected to the outer side of the pressure plate 13. By utilizing the telescopic movement of the output shaft inside the electric push rod 14, the pressure plate 13 can not only press on the support plate 12 to fix the inner cylinder 2, but also be removed from the support plate 12 to disassemble the inner cylinder 2.
[0019] Extension rods 15 are fixedly installed on the front and rear sides of the outer wall of the inner cylinder 2, and the outer wall of the extension rods 15 is movably engaged with the inner wall of the support plate 12. Pull rods 16 are fixedly installed on the left and right sides of the upper end face of the inner cylinder 2.
[0020] Please see Figure 2 , Figure 8 and Figure 9 A water outlet pipe 18 is fixedly installed on the upper end of the water pump 4. A connecting pipe 17 is fixedly connected to the end of the water outlet pipe 18 away from the water pump 4. The lower end of the connecting pipe 17 is fixedly connected to the upper end of the nozzle 3. The front and rear sides of the connecting pipe 17 are fixedly connected to the upper end of the machine body 1. A water inlet pipe 19 is fixedly installed on the right side of the water pump 4, and the end of the water inlet pipe 19 away from the water pump 4 extends into the interior of the machine body 1. When the power to the water pump 4 is turned on, the flotation liquid in the machine body 1 flows into the interior of the water inlet pipe 19. A filter screen is installed at the connection of body 1. The flotation liquid before entering the inlet pipe 19 can be filtered to remove impurities. After the impurities are removed, the flotation liquid enters the outlet pipe 18 and the connecting pipe 17 in sequence, and then is sprayed into the interior of body 1 from the nozzle 3. A filter screen is fixedly installed on the inner wall of the connection between the inlet pipe 19 and body 1. By installing a filter screen at the connection between the inlet pipe 19 of the water pump 4 and body 1, the flotation liquid before entering the inlet pipe 19 can be filtered to remove impurities, thereby avoiding the blockage of the pipe and nozzle 3 by impurities in the flotation liquid.
[0021] The outer wall of the turntable 5 is evenly distributed with several balls 21 located on the inner side of the lower end of the inner cylinder 2. The side of the balls 21 away from the turntable 5 is rotatably connected to the inner wall of the lower end of the inner cylinder 2. The lower end of the turntable 5 is provided with a slot 20 located above the drive motor 8. The upper end of the turntable 5 is fixedly installed with a locking block 22.

The outer wall of the round rod 24 is fixedly connected with a connecting rod 23, and the end of the connecting rod 23 away from the round rod 24 is fixedly connected to the inner side of the brush plate 7.
[0022] Please see Figure 3 , Figure 6 and Figure 7 A housing 26 is fixedly mounted on the outer wall of the drive motor 8, and the upper end of the housing 26 is fixedly connected to the bottom surface of the body 1. A rotating shaft 27 is fixedly connected to the upper end of the output shaft of the drive motor 8. An installation plate 28 located inside the body 1 is fixedly mounted on the upper end of the rotating shaft 27. A locking block 29 is fixedly mounted inside the installation plate 28. A rubber gasket 30 is fixedly sleeved on the outer wall of the locking block 29, and the outer wall of the rubber gasket 30 is movably engaged with the inner wall of the slot 20. Since the rubber gasket 30 has a certain elasticity, the rubber gasket 30 installed between the locking block 29 and the slot 20 can increase the tightness of the turntable 5 installed in the installation plate 28.
[0023] A rotating rod 31 is fixedly installed on the inner side of the scraper 9, and a rotary motor 32 is fixedly installed at the rear end of the rotating rod 31. After the rotary motor 32 is turned on, it drives the scraper 9 to move on the surface of the flotation liquid through the connection of the rotating rod 31, thereby accelerating the outflow of light impurities on the surface of the flotation liquid. A housing 33 is fixedly installed on the outer wall of the rotary motor 32, and the housing 33 is fixedly installed on the machine body 1.
[0024] Working principle: In use, firstly, the waste aluminum alloy with flotation is added into the inner cylinder 2, and then the inner cylinder 2 is placed into the machine body 1 through the pull rod 16. At this time, the slot 20 and the block 29 are engaged. Since the rubber gasket 30 has a certain elasticity, the rubber gasket 30 installed between the block 29 and the slot 20 can increase the tightness of the turntable 5 installed in the mounting plate 28. At the same time, the extension rod 15 is engaged in the tray 12. Turn on the power of the electric push rod 14, and use the extension of the output shaft in the electric push rod 14 to move the pressure plate 13 to the upper end of the extension rod 15, so that the pressure plate 13 can restrict the position of the extension rod 15 in the tray 12. Then, the external flotation solution, which can be water, is continuously introduced into the interior of the machine body 1 from above. When the level of the flotation solution inside the machine body 1 reaches the overflow outlet 10, the light impurities floating on the surface of the flotation solution can be discharged from the overflow outlet 10 to the outside of the machine body 1. The flow rates of the external flotation solution and the water pump 4 can be adjusted according to specific circumstances. The power supply of the rotary motor 32 is turned on. After the rotary motor 32 is turned on, it drives the scraper 9 to move on the surface of the flotation solution through the connection of the rotating rod 31, accelerating the flow of light impurities on the surface of the flotation solution. Subsequently, the power supply of the drive motor 8 is turned on. Then, the rotating disk 5 is driven to rotate at the bottom of the inner cylinder 2 through the connection of the rotating shaft 27, mounting plate 28, rubber pad 30, locking block 29, and locking groove 20. At this time, the ball bearing 21 rolls between the rotating disk 5 and the inner cylinder 2, reducing the friction between the contact surface of the rotating disk 5 and the inner cylinder 2. While the rotating disk 5 is moving, the brush plate 7 is driven to rotate in the inner cylinder 2 through the connection of the locking block 22, fixing block 25, spring clip 6, round rod 24 and connecting rod 23, so that the brush plate 7 comes into contact with the waste aluminum alloy, and the waste aluminum alloy comes into full contact with the flotation liquid, thereby improving the flotation effect of the waste aluminum alloy and preventing impurities from being hidden in the accumulated waste aluminum alloy. Then, the power of the water pump 4 is turned on. The water pump 4 turns on and the flotation liquid in the machine body 1 flows into the water inlet pipe 19. Since a filter screen is installed at the connection between the water inlet pipe 19 and the machine body 1, the flotation liquid before entering the water inlet pipe 19 can be filtered to remove impurities. The flotation liquid after removing impurities enters the water outlet pipe 18 and the connecting pipe 17 in sequence, and then is sprayed into the machine body 1 from the nozzle 3, so that the flotation liquid of the waste aluminum alloy can be recycled. Finally, after the waste aluminum alloy in the machine body 1 has completed flotation, turn off the power of the drive motor 8, and the brush plate 7 will stop rotating in the inner cylinder 2. Open the valve on the drain pipe 11, and the flotation liquid in the machine body 1 can be discharged from the drain pipe 11 to the outside of the machine body 1. Turn on the power of the electric push rod 14, and use the retraction of the output shaft in the electric push rod 14 to drive the pressure plate 13 to move on the extension rod 15. After the pressure plate 13 separates from the extension rod 15, the pressure plate 13 can be taken out from the inside of the support plate 12. The operator takes out the inner cylinder 2 from the inside of the machine body 1 through the pull rod 16. When the inner cylinder 2 is lifted upward, the extension rod 15 separates from the support plate 12, and at the same time, the locking block 29 separates from the locking groove 20, thus completing the removal of the waste aluminum alloy in the inner cylinder 2 from the machine body 1.
