[0002] Recycled aluminum is aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and scrap aluminum alloy materials or aluminum-containing waste materials. It is an important source of metallic aluminum. The recycling of scrap aluminum in my country mainly adopts pyrometallurgy, and the smelting process will produce waste gas that affects the environment. These waste gases and smoke contain various metal oxides and non-metal oxides, and may also contain harmful substances, which will pollute the environment. Therefore, corresponding purification devices are needed to purify these waste gases.

[0003] Publication No. "CN220238173U" provides a waste gas purification device for recycled aluminum smelting. Through the setting of a driving mechanism, the blades can be driven to rotate in the purification box, which can effectively and repeatedly disperse the water sprayed from the nozzle, fully atomize it, increase the contact area with the waste gas, and more fully absorb the dust, sulfides and nitrides in the flue gas. Through the setting of the filter net and the activated carbon plate, the incompletely dissolved particles and odors can be processed.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the exhaust gas purification device can effectively break up and atomize the water sprayed from the nozzle repeatedly through the rotating blades, there is no structure inside the purification device to filter impurities in the purified water, which causes the impurities in the purified water to easily clog the pump body, thereby affecting the service life of the pump body. In addition, the first bevel gear and the second bevel gear in the device are directly exposed to the outside. Therefore, in actual use, water stains are easily adhered to their surfaces to cause rust, thereby reducing the service life of the first bevel gear and the second bevel gear, and the practicality is poor.

[0033] On the basis of the first embodiment, in this embodiment, by starting the low-speed motor 31, the low-speed motor 31 drives the transmission vertical rod 35 to rotate through the transmission shaft 38, the active bevel gear 37 and the driven bevel gear 39, and then the transmission vertical rod 35 drives the scattering blades 34 and the follower plate 312 to rotate at a low speed. In this process, the rotating scattering blades 34 can repeatedly scatter the alkaline solution sprayed from the spray disk 28 to make it fully atomized, thereby increasing the contact area between the alkaline solution and the exhaust gas, and the follower plate 312 rotating at a low speed will drive the silicone scraper 311 to rotate to scrape off a part of the impurities blocked by the upper end surface of the filter residue mesh plate 22, thereby extending the cleaning cycle of the filter residue mesh plate 22.

[0034] The rotating assembly 3 includes a low-speed motor 31, a scattering blade 34, a transmission vertical rod 35, a protective shell 36, an active bevel gear 37, a transmission shaft 38, a driven bevel gear 39, a silicone scraper 311 and a follower plate 312. A protective shell 36 is installed on the upper side of the purification tank 1. The protective shell 36 is connected to the support rod 362 by welding. The protective shell 36 can protect the active bevel gear 37 and the driven bevel gear 39. The protective shell 36 is installed with a transmission vertical rod 35. The transmission vertical rod 35 is connected to the scattering blades 34, the limit ring 351 and the follower plate 312 by welding. The transmission vertical rod 35 will drive the scattering blades 34 and the follower plate 312 to rotate. The scattering blades 34 are arranged on the upper side of the annular side of the transmission vertical rod 35. The scattering blades 34 can repeatedly scatter the alkaline solution sprayed from the spray disk 28 when rotating, so as to make it fully atomized, thereby increasing the contact area between the alkaline solution and the exhaust gas, thereby removing acidic gases and dust such as sulfur dioxide in the regenerated aluminum exhaust gas.

[0035] A follower plate 312 is provided on the lower side of the annular side surface of the transmission vertical rod 35, and the follower plate 312 will drive the silicone scraper 311 to rotate. A silicone scraper 311 is installed on the front end surface of the follower plate 312, and the bottom of the silicone scraper 311 is in contact with the upper end surface of the filter residue mesh plate 22. When the silicone scraper 311 rotates, it can scrape off impurities accumulated on a part of the upper end surface of the filter residue mesh plate 22. A driven bevel gear 39 is provided on the upper side of the annular side surface of the transmission vertical rod 35, and the driven bevel gear 39 can rotate the transmission vertical rod 35. A driving bevel gear 37 is meshed with the left side of the annular side surface of the driven bevel gear 39. The driving bevel gear 37 is connected to the transmission shaft 38 by welding. The driving bevel gear 37 will drive the driven bevel gear 39 to rotate. A transmission shaft 38 is provided on the left end surface of the driving bevel gear 37. A low-speed motor 31 is installed on the left end of the transmission shaft 38. The low-speed motor 31 will drive the transmission shaft 38 to rotate at a low speed, so that the transmission shaft 38 drives the driving bevel gear 37 to rotate at a low speed.

[0036] A limit stop ring 361 is installed in the middle position of the lower end surface of the protective shell 36, and a limit ring 351 is arranged on the annular side of the transmission vertical rod 35. The limit stop ring 361 and the limit ring 351 prevent the transmission vertical rod 35 from being displaced or shaking during rotation and use. Support rods 362 are symmetrically arranged on the left and right sides of the annular side of the protective shell 36. The support rods 362 can support and fix the protective shell 36. A first mechanical seal 352 is installed on the upper side of the annular side of the transmission vertical rod 35. The first mechanical seal 352 makes the transmission vertical rod 35 and the protective shell 36 more sealed, and prevents the solution from extending into the protective shell 36 through the gap. A second mechanical seal 381 is arranged on the right side of the annular side of the transmission shaft 38. The second mechanical seal 381 makes the transmission shaft 38 and the protective shell 36 more sealed, and prevents the solution from extending into the protective shell 36 through the gap.

[0037] A guide bend 33 is fixedly connected to the right side of the annular side of the purification tank 1. The guide bend 33 can guide the impurities in the guide and drop cavity 14 downward to the collecting bucket 32. The collecting bucket 32 ​​is set on the lower side of the annular side of the guide and drop cavity 33. The collecting bucket 32 ​​can temporarily store the impurities that have been guided down. A mounting screw 321 is installed on the upper side of the collecting bucket 32. The mounting screw 321 is convenient for the staff to disassemble and clean the collecting bucket 32 ​​later. A guide and drop cavity 14 is opened on the right side of the annular side of the purification tank 1, and the guide and drop cavity 14 is connected to the guide and drop bend 33. The guide and drop cavity 14 is convenient for guiding the impurities scraped off by the silicone scraper 311 into the guide and drop bend 33. A shielding inclined plate 13 is fixedly connected to the right side of the annular side of the purification tank 1. The shielding inclined plate 13 prevents a part of the sprayed solution from flowing into the guide and drop cavity 14. A sealing ring is arranged between the collecting bucket 32 ​​and the guide and drop bend 33. The sealing ring makes the sealing between the collecting bucket 32 ​​and the guide and drop bend 33 better.

[0038] Working principle: During the purification process of the regenerated aluminum waste gas, the staff first starts the circulation pump 23 and the external blower, so that the circulation pump 23 transports the alkaline solution in the liquid storage chamber 21 to the spray plate 28 through the liquid outlet pipe 24, and the spray plate 28 will disperse and spray the alkaline solution entering the interior downward. At the same time, the air inlet pipe 4 will guide the regenerated aluminum waste gas to be purified into the purification tank 1. At this time, the alkaline solution dispersed and sprayed downward will contact the regenerated aluminum waste gas entering the purification tank 1, and remove the alkaline solution in the regenerated aluminum waste gas. Most of the acidic gases and dust such as sulfur dioxide will be removed, and the sprayed alkaline solution will continue to fall downward to the liquid storage chamber 21 for recycling. In this process, the filter residue mesh plate 22 will filter the alkaline solution and block the large particles of insoluble matter in the alkaline solution to prevent the circulation pump 23 from being easily blocked during use. The regenerated aluminum waste gas after spray purification will pass through the gas-liquid filter 29 and be sucked into the air guide shell 25. At this time, the first purification mesh plate 27 and the second purification mesh plate 26 will adsorb and purify the regenerated aluminum waste gas again. The purified regenerated aluminum waste gas will be sucked into the external blower through the outlet pipe 6 and discharged to the outside; while the regenerated aluminum waste gas is being purified, the staff starts the low-speed motor 31, so that the low-speed motor 31 drives the active bevel gear 37 to rotate through the transmission shaft 38, and the active bevel gear 37 drives the transmission vertical rod 35 to rotate through the driven bevel gear 39, and then the transmission vertical rod 35 drives the scattering blades 34 and the follower plate 312 to rotate at a low speed. In this process, the rotating scattering blades 34 can spray the alkali sprayed from the spray plate 28. The alkaline solution is repeatedly broken up to be fully atomized, thereby increasing the contact area between the alkaline solution and the exhaust gas, and the follower plate 312 rotating at a low speed will drive the silicone scraper 311 to rotate, so that the silicone scraper 311 rotating at a low speed can scrape off a part of the impurities blocked by the upper end surface of the filter residue mesh plate 22, and at the same time, the guide cavity 14 will guide most of the impurities scraped off by the silicone scraper 311 to the guide bend 33, so that the guide bend 33 can concentrate the impurities and guide them to the collection bucket 32 ​​for collection, thereby extending the cleaning cycle of the filter residue mesh plate 22.
