Description

Technical Field

[0001] The utility model relates to the technical field of concentrators, in particular to a stable driving device for a central transmission concentrator. Background Art

[0002] A concentrator is a continuously operating concentrating and clarifying device primarily used for dewatering concentrate and tailings slurries in wet beneficiation operations. It is also widely used for concentrating and purifying solid-containing slurries in industries such as coal, steel, chemicals, building materials, water resources, and sewage treatment. During the concentrating process, existing center-drive rake concentrators rotate a main shaft driven by a drive mechanism. A rake frame, located at the base of the main shaft, scrapes the material within the concentrating tank. This high-speed rotation of the main shaft can easily cause the rake frame to shift, which can affect the rake frame's rotation. Collision between the rake frame and the concentrator's inner wall can damage the concentrator, increasing costs. Therefore, the stability of the drive mechanism is crucial. Utility Model Content

[0028] A rotatable detection mechanism 3 is provided under the working bridge 11. The detection mechanism 3 includes a first gear 31. The first gear 31 is fixedly sleeved on the outer wall of the main shaft 13. The driving assembly 12 drives the main shaft 13 to rotate, and the first gear 31 also rotates accordingly. An axially distributed first slide groove 14 is provided at the bottom of the working bridge 11. An elastically connected first slider 15 is provided in the first slide groove 14. A fixedly connected second rotating seat 32 is provided at the bottom of the first slider 15. A rotatable second gear 33 is provided in the second rotating seat 32. The axially distributed second gears 33 are all engaged with the first gear 31.

[0029] An installation cavity 34 is provided in the second gear 33. An elastically connected first fixed block 35 and a fixedly connected contact sensor 36 are provided at the bottom of the installation cavity 34. The contact sensor 36 is located below the first fixed block 35. The first fixed block 35 abuts against the first gear 31. The rotation of the first gear 31 drives the second gear 33 to rotate. The outer wall of the first gear 31 squeezes the first fixed block 35. The first fixed block 35 moves toward the bottom of the installation cavity 34 and hits the contact sensor 36. The contact sensor 36 sends a signal. When the contact sensor 36 no longer sends a signal, it indicates that the main shaft 13 drives the second gear 33 to deviate.

[0030] A movable adjustment mechanism 4 is provided in the concentrator 1, and the adjustment mechanism 4 includes a first connecting rod 41. The adjustment mechanism 4 is located below the detection mechanism 3. An axially distributed first connecting rod 41 is fixedly provided at the bottom of the working bridge 11, and a rotatably connected second connecting rod 42 is provided at the bottom of the first connecting rod 41. A torsion spring is provided in the second connecting rod 42, and the other end of the axially distributed second connecting rod 42 is also provided with a fixedly connected ring 43. An axially distributed third rotating seat 44 is fixedly provided on the outer wall of the ring 43, and elastically connected arc blocks 45 are evenly provided on the inner wall of the ring 43. The arc blocks 45 abut against each other, and the number of arc blocks 45 is consistent with the number of third rotating seats 44. When the main shaft 13 deviates, the corresponding arc blocks 45 are also squeezed.

[0031] The inner wall of the arc block 45 is provided with axially distributed balls, which abut against the main shaft 13. The rotation of the main shaft 13 drives the balls to rotate. A rotatable third connecting rod 46 is provided in the third rotating seat 44, and the other end of the third connecting rod 46 is provided with a fixedly connected second fixed block 47. A slidable fourth connecting rod 48 is provided in the second fixed block 47. The other end of the fourth connecting rod 48 extends to the outside of the second fixed block 47 and is rotatably connected to the first rotating seat 21. The second fixed block 47 is hollow inside, and a rotatable third gear 471 and a fixedly connected first telescopic column 472 are provided in the second fixed block 47. A spring is wound around the outside of the first telescopic column 472.

[0032] The other end of the first telescopic column 472 is fixedly connected to the fourth connecting rod 48 at the internal port of the second fixed block 47. A uniformly distributed tooth block 481 is fixed on one side wall of the fourth connecting rod 48. The tooth block 481 is located inside the second fixed block 47, and the tooth block 481 is engaged with the third gear 471. The rotation of the third gear 471 drives the tooth block 481 to move, and the fourth connecting rod 48 also moves toward the inside of the second fixed block 47. A uniformly distributed first wedge block 482 is fixed on the other side wall of the fourth connecting rod 48. The first wedge block 482 is located inside the second fixed block 47. A fixedly connected motor 473 is installed on the top of the second fixed block 47, and a protective cover is provided on the outside of the motor 473.

[0033] The output shaft of the motor 473 is fixedly connected to the rotating shaft of the third gear 471. The rotation of the motor 473 drives the third gear 471 to rotate. An electric cylinder 474 is connected to the side wall of the second fixed block 47. A protective cover is provided on the outside of the electric cylinder 474. The telescopic end of the electric cylinder 474 is provided with a fixedly connected second telescopic column 475. The second telescopic column 475 is located inside the second fixed block 47. A spring is wound around the outside of the second telescopic column 475. The other end of the second telescopic column 475 is provided with a fixedly connected second wedge block 476. The second wedge block 476 is engaged with the first wedge block 482, which plays a limiting role in the process of the fourth connecting rod 48 moving into the second fixed block 47.

[0034] After the concentrator 1 is completed, the electric cylinder 474 is started, and the telescopic rod of the electric cylinder 474 contracts to drive the second wedge block 476 to move outside the second fixed block 47. The second wedge block 476 is separated from the first wedge block 482, and the fourth connecting rod 48 can be restored to its original position.

[0035] In the present invention, during actual operation, the drive assembly 12 in the concentrator 1 drives the main shaft 13 to rotate, and the first gear 31 also rotates accordingly, driving the axially distributed second gear 33 to rotate. The outer wall of the first gear 31 squeezes the first fixing block 35, and the first fixing block 35 moves toward the bottom of the installation cavity 34 and hits the contact sensor 36. The contact sensor 36 sends a signal. When the contact sensor 36 no longer sends a signal, it indicates that the main shaft 13 has driven the second gear 33 to deviate.

[0036] When the main shaft 13 is offset, the corresponding arc block 45 is also squeezed, and the motor 473 in the direction where there is no signal from the contact sensor 36 is started. The rotation of the motor 473 drives the third gear 471 to rotate, and the tooth block 481 also moves, driving the fourth connecting rod 48 to move toward the inside of the second fixed block 47. The second wedge block 476 engages with the first wedge block 482 to limit the fourth connecting rod 48. The total length of the third connecting rod 46 and the fourth connecting rod 48 becomes shorter, and the offset main shaft 13 can be fine-tuned to ensure that the drive assembly 12 drives the main shaft 13 to rotate more stably.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
