Description

Technical Field

[0001] This invention relates to the field of concentrators, specifically to a filtration device for an anti-clogging extraction and concentrator. Background Technology

[0002] A thickener is a continuously operating thickening and clarification device, mainly used for dewatering concentrate and tailings slurries in wet mineral processing. It is also widely used for thickening and purifying solid-containing slurries in coal, steel, chemical, building materials, water supply, and wastewater treatment industries. Ordinary thickeners are reliable, have low operating costs, and can store and buffer the feed, while high-efficiency thickeners mainly use the rational use of flocculants and bottom-feeding methods to improve settling velocity.

[0003] In existing center-driven rake thickeners, material accumulation is common during the thickening process due to the rake frame's rotation scraping the material inside the thickening tank. This prevents the material from moving promptly to the center of the tank, increases resistance on the rake frame, leads to more frequent rake lifting, and reduces efficiency. Furthermore, the slow settling and mixing of internal material before it can be scraped by the rake frame results in prolonged thickening times. When the volume of internal material is large, the discharge port is prone to blockage. Summary of the Invention

The positioning pins can pass through the third circular hole 353. A rotatable cleaning block 36 is provided between the filter plate 23 and the bottom of the flow stabilizer 21. The cleaning block 36 is located below the filter plate 23. A fourth circular hole 361 is opened at the center of the cleaning block 36. The main shaft 19 can pass through the fourth circular hole 361. The cleaning block 36 is fixedly connected to the main shaft 19.

When the cleaning block 36 rotates, the second cleaning brush 362 can clean the inner wall of the bottom of the flow stabilizer 21, reducing the probability of the first circular hole 22 being blocked.

[0049] The bottom of the main shaft 19 is provided with a rotatable second cleaning mechanism 4. The second cleaning mechanism 4 includes a rake frame 41, which is fixedly connected to the bottom of the main shaft 19. A rake lifting mechanism is installed above the rake frame 41.

The first motor 425 is provided with a waterproof cover to isolate sewage. The output shaft of the first motor 425 is fixedly connected to the first threaded rod 423. The rotation of the first motor 425 drives the first threaded rod 423 to rotate. The second motor 426 is fixedly connected to the inside of the mounting plate 42. The output end of the second motor 426 is provided with a fixedly connected second threaded rod 427. The second threaded rod 427 is provided with a fixedly connected second fixing block 428.

The side wall of the second long rake 44 is equipped with a fixedly connected first rotating seat 442. The second threaded rod 427 is rotatably connected to the first rotating seat 442. When the second motor 426 is started, the second motor 426 rotates and drives the second threaded rod 427 to rotate, and the first long rake 43 also rotates. When the rake frame 41 is lifted upward, the first long rake 43 rotates until the rake tip faces upward. When the first motor 425 is started, the limit block 424 moves and locks the second fixing block 428, and the position of the first long rake 43 is fixed. At this time, the rake frame 41 rotates, and the first long rake 43 can clean the outside of the flow stabilizing cylinder 21, reducing the chance of the flow stabilizing cylinder 21 being blocked.

[0054] The second connecting column 453 can be inserted into the circular groove 446. The bottom of the protective cover 451 and the top of the second long rake 44 are both equipped with sealing strips. The compression of the two sealing strips can prevent sewage from entering the interior of the protective cover 451. The hydraulic rod 447 can be stretched to lift the third long rake 45. The third long rake 45 is perpendicular to the second long rake 44. The third long rake 45 can clean the inner wall of the thickener 1 and reduce the chance of the thickener 1 getting clogged.

[0055] Working principle:

[0056] In use, before the wastewater enters the thickening tank, the electric hook 141 is activated to lift the first sliding column 311 to the lower end of the first through groove 25. The lever rotates, the angle sensor 26 sends a signal, and the extension rod of the second electric cylinder 357 is compressed. The first connecting column 312 at the bottom of the disc 31 is pressed by the top of the first fixed column 24, and the first connecting column 312 slides into the disc 31. The auxiliary wheel 313 slides along the second inclined groove 355, driving the locking block 35 to move closer to the main shaft 19. When the two locking blocks 35 are fully engaged... When engaged, the contact sensor 359 sends a signal. At this time, the two locking blocks 35 are threadedly engaged with the main shaft 19. When the contact sensor 359 does not send a signal, it means that the threads of the two locking blocks 35 and the main shaft 19 are not fully engaged. The drive assembly 16 is activated, and the main shaft 19 rotates until the contact sensor 359 sends a signal and then the drive assembly 16 is turned off. Then the two first electric cylinders 356 are stretched, which drives the positioning pin to engage in the third round hole 353 near the locking block 35, and the position of the two locking blocks 35 is fixed.

[0057] Start drive assembly 16, spindle 19 rotates, block 35 drives disk 31 to move upward. When the first sliding column 311 slides to the upper end of the first through groove 25, lever rotates, angle sensor 26 sends a signal. At this time, the first electric cylinder 356 extends and retracts, the first connecting column 312 at the top of disk 31 is squeezed by the bottom of bridge frame 14, the first connecting column 312 slides into disk 31, the auxiliary wheel 313 slides along the first inclined groove 354, driving block 35 to move away from spindle 19, the second electric cylinder 357 extends, driving the positioning pin to engage with the first through groove 35 away from block 35. Inside the three circular holes 353, the two locking blocks 35 separate from the main shaft 19, the disc 31 descends, and the first cleaning brush 33 also descends. The first cleaning brush 33 can pass through the filter holes in the filter plate 23 and clean the filter plate 23. Then the electric hook 141 is started again. The electric hook 141 hooks the two first sliding columns 311 and moves them upward. The disc 31 also moves upward. After moving to the specified height, it stops and the position of the disc 31 is fixed. At this time, the first cleaning brush 33 does not affect the normal filtration of the filter plate 23. The cleaning of the filter plate 23 can also be carried out after the sewage settles.

[0058] Then, the wastewater enters the inside of the flow stabilizer 21 through the feed pipe 17. The flocculant enters the flow stabilizer 21 and mixes with the wastewater. The drive assembly 16 is started, the main shaft 19 rotates, which drives the cleaning block 36 to rotate. The second cleaning brush 362 also rotates. The rotating second cleaning brush 362 can clean the bottom inner wall of the flow stabilizer 21, reducing the chance of the first round hole 22 being blocked. The treated wastewater flows out from the first round hole 22. The rake frame 41 rotates, which can make the treated internal material enter the bottom discharge pipe 18 of the thickener 1 faster and be discharged. A rake lifting mechanism is installed above the rake frame 41.

[0059] When the rake lifting mechanism drives the rake frame 41 to rise, the second motor 426 is started. The rotation of the second motor 426 drives the second threaded rod 427 to rotate, and the first long rake 43 also rotates. When the first long rake 43 rotates to the point where the rake tip is facing upward, the first motor 425 is started, the limit block 424 moves, and the second fixing block 428 is locked, and the position of the first long rake 43 is fixed. At this time, the rotating rake frame 41 can drive the first long rake 43 to rotate along the outer wall of the flow stabilizer 21, which can clean the impurities adhering to the outer wall of the flow stabilizer 21.

[0060] After all the water in the thickener 1 is drained, the third electric cylinder 445 is activated. The third electric cylinder 445 stretches and drives the limit rod 444 to slide outward along the second slide groove 449. The second connecting column 453 is unlocked from the circular groove 446. The hydraulic rod 447 is stretched to lift the third long rake 45. The third long rake 45 is perpendicular to the second long rake 44. The rake frame 41 is rotated, and the third long rake 45 also rotates. The rotating third long rake 45 can clean the inner wall of the thickener 1. After the inner wall of the thickener 1 is cleaned, the hydraulic rod 447 is compressed back to its initial state. The two sealing strips at the bottom of the protective cover 451 and the top of the second long rake 44 are squeezed to prevent sewage from entering the interior of the protective cover 451. Multiple cleaning can better prevent the thickener 1 from clogging.
