Description

Technical Field

[0001] The utility model relates to the technical field of red mud treatment, in particular to a dust collecting mechanism for flue gas after red mud fission reaction. Background Art

[0002] Red mud is the waste residue discharged after the extraction of alumina, which contains iron, titanium and other rare and precious metals. However, the extraction of other elements in red mud is relatively complicated in the existing technology. Red mud is also polluting and directly discharging it into the environment will pollute the surrounding environment. It is difficult to directly recover the useful components in red mud. The existing technology mixes red mud and a reducing agent together for calcination. The properties of the calcined red mud may change, and then the calcined red mud is poured into an aqueous solution for further reaction. The calcined red mud is prone to produce a large amount of smoke when it comes into contact with an aqueous solution. If these fumes are directly discharged into the environment, they will cause harm to environmental safety.

[0003] The utility model patent with the announcement number CN218079615U discloses a red mud thermal reaction fission treatment device, in which a fission chamber and a pressing mechanism are set up; the fission chamber includes a fission chamber, a feed port, a discharge port and a liquid inlet; the fission chamber is a closed structure; the feed port is set in the middle of the side wall of the fission chamber, and the red mud material enters the fission chamber from the feed port; the discharge port is set at the bottom of the fission chamber, and the discharge port is used to discharge the mixed red mud slurry; wherein the liquid inlet is set on the side wall of the fission chamber, and the liquid inlet is used to add an aqueous solution to the fission chamber; the pressing mechanism includes a pressing plate, a rotating shaft and a driving assembly. The pressing mechanism presses the red mud material entering the aqueous solution into the aqueous solution by rotating, so that the high-temperature red mud material is fully in contact with the aqueous solution to carry out a fission reaction.

[0004] However, there are still some shortcomings in the above scheme. The above scheme has poor treatment effect on the flue gas after the red mud reaction. In the above scheme, the smoke dust is only treated by spraying water. The flue gas generated by the red mud after the reaction is mostly insoluble solid particles. After the flue gas is treated by spraying water, the smoke dust will flow along the treatment structure with the water flow and adhere to the inner wall of the treatment structure after the spraying water evaporates. It is difficult to clean, which can easily lead to blockage of the treatment structure and affect its use. In view of this, we propose a dust collection mechanism for flue gas after red mud fission reaction. Utility Model Content

[0026] A dust collecting mechanism for flue gas after red mud fission reaction, such as Figure 1-Figure 5As shown, it includes a flue gas treatment tank 1; a dust removal mechanism 2 is arranged inside the flue gas treatment tank 1, and the dust removal mechanism 2 includes a dust filter plate 201, the dust filter plate 201 is fixedly connected to the top of the flue gas treatment tank 1, a collecting tube 202 is fixedly connected in the middle of the dust filter plate 201, a sealing cover 203 is movably connected to the bottom of the collecting tube 202, a collecting groove 204 is provided on the side of the collecting tube 202, a collecting frame 205 is rotatably connected inside the collecting groove 204, a collecting pipe 206 is fixedly connected to the collecting frame 205, and a collecting hole 207 is provided on the collecting pipe 206. The dust removal mechanism 2 can be used to collect the flue gas generated after the red mud fission reaction. The smoke filter 201 is a double-layer structure, which can filter the smoke particles in the exhaust gas and block the smoke on the smoke filter plate 201. At the same time, the collecting tube 202 can process the smoke accumulated on the smoke filter plate 201 while filtering the smoke, so as to avoid the blockage of the smoke filter plate 201 affecting the filtering and dust removal effect. The collecting tube 202 with an opening at the lower end can conveniently process the smoke impurities collected inside. The collecting frame 205 structure can rotate continuously and cooperate with the collecting tube on the collecting frame 205. 206 continuously scrapes and cleans the surface of the smoke filter plate 201, and at the same time cooperates with the collection hole 207 to collect the smoke. A driving groove 208 is opened on the side of the collection tube 202. A filter screen 209 is fixedly connected to the inside of the driving groove 208. A scraper 210 is slidably connected to the inside of the filter screen 209. The scraper 210 is fixedly connected to the bottom of the collection frame 205. The driving groove 208 structure can drive the air inside the collection tube 202, so that the air inside the collection tube 202 flows from the collection hole 207 to the driving groove 208. The filter screen 209 on the driving groove 208 can filter the smoke in the air and remove it on the scraper 210. The smoke is collected inside the collecting tube 202 under continuous cleaning. A motor 211 is fixedly connected to the top of the smoke treatment tank 1. The output shaft of the motor 211 passes through the smoke treatment tank 1. A gear 212 is fixedly connected to the end of the output shaft of the motor 211. A gear ring 213 meshing with the gear 212 is fixedly connected to the top of the collecting frame 205. The motor 211 structure can drive the gear 212 to make the gear 212 rotate continuously and drive the collecting frame 205 through the meshing gear ring 213, so that the collecting tube 206 rotates continuously on the smoke filter plate 201 and collects the smoke on the smoke filter plate 201.

[0027] like Figure 1-Figure 4As shown, a switching mechanism 3 is provided inside the flue gas treatment tank 1, and the switching mechanism 3 includes a sealing plate 301, which is slidably connected to the inside of the collection pipe 206, and a sealing plug corresponding to the collection hole 207 structure is fixedly connected to the bottom end of the sealing plate 301. The switching mechanism 3 can switch the smoke filter plate 201, and the double-layer smoke filter plate 201 can realize convenient switching between filtering and cleaning collection, so that when filtering and dust removal by one smoke filter plate 201, the other smoke filter plate 201 can be cleaned, without affecting the smoke passing through. While filtering, keep the smoke filter plate 201 unobstructed to avoid blocking of the smoke filter plate 201 and affecting normal use. One end of the sealing plate 301 is rotatably connected to a guide wheel 302, and a guide rod is fixedly connected to the inside of the collection pipe 206. The guide rod passes through the sealing plate 301. The guide wheel 302 structure can support the sealing plate 301, and the guide rod structure can guide the movement of the sealing plate 301. The top of the flue gas treatment tank 1 is slidably connected to a guide frame 303, and the guide wheel 302 is slidably connected to the guide frame 303. The top of the guide frame 303 is fixedly connected There is a buffer spring 304, a driving rod 305 is fixedly connected to the side of the collection frame 205, and a driving block 306 is fixedly connected to the end of the driving rod 305. The guide frame 303 can drive the sealing plate 301 through the guide wheel 302, so that the collection hole 207 can be conveniently switched between opening and closing. At the same time, the guide frame 303 can facilitate the rolling of the guide wheel 302. The driving rod 305 structure can drive and press the guide frame 303 through the driving block 306, and realize the opening and closing of a layer of the sealing plate 301 during the movement of the guide frame 303. Another layer of sealing plate 301 is closed, and an air inlet pipe 4 is fixedly connected to the bottom end of one side of the flue gas treatment tank 1. The end of the air inlet pipe 4 is arranged at the top of the inside of the flue gas treatment tank 1. A through hole 5 corresponding to the structure of the air inlet pipe 4 is opened on the guide frame 303. An exhaust pipe 6 is fixedly connected to the middle of the inside of the flue gas treatment tank 1. The exhaust pipe 6 structure can discharge the gas after internal filtering and treatment. The bottom end of the exhaust pipe 6 passes through the collecting tube 202 and is connected to the inside of the smoke dust treatment tank. At the same time, a fan is connected to the end of the exhaust pipe 6, which can actively discharge the internal gas to the outside, thereby improving the smoke dust treatment effect.

[0028] When the dust collecting mechanism of flue gas after red mud fission reaction of the utility model is in use, the flue gas after red mud fission reaction enters the interior of the smoke treatment tank from the air inlet pipe 4. When the flue gas moves to the interior of the smoke treatment tank, the flue gas contacts the smoke filter plate 201, and the dust inside the flue gas is filtered through the smoke filter plate 201. The filtered flue gas passes through the smoke filter plate 201 and is discharged from the exhaust pipe 6. At the same time, the motor 211 continues to run and drives the gear ring 213 to rotate through the gear 212, and the driving rod 305 rotates synchronously. When the driving block 306 on the driving rod 305 moves from one guide frame 303 to the other guide frame 303, the guide frame 303 on one side is restored under the elastic action of the buffer spring 304, and at the same time, the sealing plate 301 is driven to rise synchronously when the guide frame 303 rises, and the guide frame 303 then closes the pipe opening of the air inlet pipe 4, and the sealing plate 301 opens the collecting hole 207 when it rises, while the guide frame 303 on the other side When squeezed by the driving block 306, 303 continues to descend and opens the other air inlet pipe 4. At the same time, the sealing plate 301 closes the collecting hole 207 when descending with the guide frame 303, thereby realizing the switching of the smoke filter plate 201. At the same time, the exhaust pipe 6 discharges the filtered gas to the outside during the exhaust process. Therefore, the air pressure at the driving groove 208 is reduced. The collecting pipe 206 with the opened collecting hole 207 sucks the smoke from the smoke filter plate 201 into the collecting tube 202 during the rotation. The scraper 210 that continues to rotate with the collecting frame 205 scrapes the smoke from the filter net 209, and the smoke finally falls into the collecting tube 202 for collection. When the collecting pipe 206 is opened, the corresponding air inlet pipe 4 is closed, and when the collecting pipe 206 is closed, the corresponding air inlet pipe 4 is opened, so that the smoke can be filtered through the smoke filter plate 201 to avoid the smoke directly passing through the collecting pipe 206 and affecting the filtering effect.
