Technical Field

[0001] This utility model relates to the field of alumina production technology, specifically to a settling device for alumina production. Background Technology

[0002] In the alumina production process, settling tanks are required. The leached slurry is diluted with a primary washing solution, and the diluted slurry is pumped into the settling tank. Separation occurs due to the difference in specific gravity between solids and liquids. Simultaneously, flocculants are added to cause the dispersed fine red mud particles in the slurry to aggregate, increasing their particle size and effectively improving the settling rate, thus accelerating the settling separation process.

[0003] However, current sedimentation devices for alumina production involve directly adding flocculants into the sedimentation tank, and the reaction time between the flocculants and the slurry is long, resulting in inconvenience in use. Therefore, we propose a sedimentation device for alumina production. Utility Model Content

Detailed Implementation

[0021] 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.

[0023] Specifically, the settling mechanism 1 includes a settling box 101, a discharge pipe 102 welded to the bottom of the settling box 101, and a first gate valve 103 installed inside the discharge pipe 102. By opening the first gate valve 103, the flocculated solids are discharged from the discharge pipe 102.

[0024] Specifically, the transmission mechanism 3 includes a transmission cylinder 301. A first motor 302 is provided at one end of the transmission cylinder 301. A first rotating shaft 304 is installed at the output end of the first motor 302. A spiral blade 305 is welded to the surface of the first rotating shaft 304. A first feed cylinder 303 and a first guide cylinder 306 are provided on the surface of the transmission cylinder 301. One end of the first guide cylinder 306 is connected to the settling tank 101. The diluted slurry enters the transmission cylinder 3 through the first feed cylinder 303. The first rotating shaft 304 is driven to rotate by the first motor 302, causing the spiral blade 305 to rotate. The slurry then enters the settling tank 101 through the first guide cylinder 306.

[0025] Specifically, the storage mechanism 4 includes a storage box 401, a second feed cylinder 402 on the top of the storage box 401, a second guide cylinder 406 welded to the bottom of the storage box 401, a second gate valve 407 installed inside the second guide cylinder 406, a desiccant cylinder 403 inside the storage box 401, a plurality of round holes 404 evenly spaced on the surface of the desiccant cylinder 403, and a cover 405 threaded to the top of the desiccant cylinder 403. The flocculant is fed into the storage box 401 through the second feed cylinder 402, and then the cover 405 is removed from the top of the desiccant cylinder 403 by manually twisting it, and the desiccant is placed inside the desiccant cylinder 403 to prevent the flocculant from getting damp. Then, the second gate valve 407 is opened to allow the flocculant to enter the settling tank 101 through the second guide cylinder 406.

[0026] Specifically, the filtration mechanism 5 includes a filter box 501. A water pump 502 is installed on the top of the filter box 501. A water pump pipe 503 is installed at the input end of the water pump 502. One end of the water pump pipe 503 is connected to the settling tank 101. A water guide pipe 505 is installed at the output end of the water pump 502. One end of the water guide pipe 505 is connected to the filter box 501. A third gate valve 504 is installed inside the water pump pipe 503. Two slots 511 are symmetrically arranged on the surface of the filter box 501. Insert blocks 510 are inserted into the inside of the two slots 511. Insert holes are opened on the surface of both the insert blocks 510 and the slots 511. Insert rods 512 are inserted into the inside of the insertion holes. A connecting plate 508 is welded to one end of the insert block 510. A handle 509 is installed on the surface of the 8, and two filter plates 506 are installed on the other surface of the connecting plate 508. By opening the third gate valve 504 inside the water pump 503, water is pumped into the filter box 501 in conjunction with the water pump 502 and the water guide pipe 505. The water is then filtered by the filter plates 506 to remove any accidentally drawn flocculent solids from the water. The water is then discharged through the drain pipe 507. By removing the insert rod 512 from the insert block 510 and slot 511, the insert block 510 and slot 511 are no longer fixed. The insert block 510 is then moved out of the slot 511 by the handle 509. The used filter plates 506 can be removed from the filter box 501 for cleaning.

[0027] Specifically, the mixing mechanism 6 includes a second motor 601, which is installed on the top of the settling tank 101. A second rotating shaft 602 is installed at the output end of the second motor 601. A stirring blade 604 is welded to the surface of the second rotating shaft 602. Two connecting rods 603 are symmetrically welded to the surface of the second rotating shaft 602. Two scrapers 605 are welded to the two ends of the two connecting rods 603 respectively. The second rotating shaft 602 is driven to rotate by the second motor 601, which causes the stirring blades 604 to rotate, so that the slurry and flocculant are fully mixed and uniform, and the slurry and flocculant react quickly to flocculate. When cleaning is required, the second rotating shaft 602 is driven to rotate by the second motor 601, which causes the connecting rods 603 to rotate, and the scrapers 605 to rotate, scraping the inner wall of the settling tank 101 to clean the settling tank 101. The scrapers 605 are in close contact with the settling tank 101.

[0028] All electrical devices in this invention are powered by an external power source;

[0029] Working principle: Diluted slurry enters the transfer cylinder 3 through the first feed cylinder 303. The first motor 302 drives the first rotating shaft 304 to rotate, causing the spiral blade 305 to rotate. The slurry then enters the settling tank 101 through the first guide cylinder 306. Flocculant enters the storage tank 401 through the second feed cylinder 402. The cover 405 is manually twisted to remove it from the top of the desiccant cylinder 403, and the desiccant is placed inside. The second gate valve 407 is opened to allow the flocculant to enter the settling tank 101 through the second guide cylinder 406. The second motor 601 drives the second rotating shaft 602 to rotate, causing the stirring blade 604 to rotate, ensuring thorough and uniform mixing of the slurry and flocculant. This rapid reaction between the slurry and flocculant facilitates flocculation. Finally, the third gate valve 504 inside the water pump 503 is opened, coordinating with the water pump. Water is drawn into the filter box 501 via pipe 502 and water guide pipe 505, and then filtered through filter plate 506 to remove any accidentally drawn-out flocculent solids. The water is then discharged through drain pipe 507. By removing the insert rod 512 from the insert block 510 and slot 511, the insert block 510 and slot 511 are unsecured. The insert block 510 is then moved out of slot 511 via handle 509, and the filter plate 506 is removed from the filter box 501 for cleaning. The first gate valve 103 is then opened to discharge the flocculent solids from discharge pipe 102. The second motor 601 drives the second rotating shaft 602 to rotate, causing the connecting rod 603 to rotate, which in turn causes the scraper 605 to rotate and scrape the inner wall of the settling tank 101 for cleaning. The scraper 605 is in close contact with the settling tank 101.
