Description

Technical Field

[0001] The invention relates to the technical field of scrapers, in particular to a scraper for ore flotation. Background Art

[0002] Flotation machine is the abbreviation of flotation concentrator, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the slurry treated with reagents is stirred and aerated so that some of the mineral particles are selectively fixed on the bubbles, float to the surface of the slurry and are scraped off to form foam products, while the rest are retained in the slurry to achieve the purpose of separating minerals. There are many structural forms of flotation machines, and the most commonly used one is the mechanical stirring flotation machine.

[0003] The existing ore flotation machine is mostly used in the process of using the ore pulp and water injected into the flotation machine, and then the motor drives the impeller to rotate through the belt, so that the impeller rotates in the water and generates centrifugal effect to form negative pressure. On the one hand, sufficient air is sucked in to mix with the ore pulp to generate bubbles, and on the other hand, the ore pulp is stirred and mixed with the drug, and the bubbles are refined at the same time, so that the useful minerals are adhered to the bubbles, so that the useful ore floats to the surface with the bubbles to form mineralized foam, and the useless waste rock remains in the flotation machine. Then the scraper is driven by the motor to rotate to scrape off the mineralized foam with useful ore, thereby realizing the flotation of the ore. However, with the flotation of the ore pulp, the small volume of slag in the ore pulp is difficult to be floated, which causes the flotation effect to deteriorate, and the slag precipitation is easy to form in the flotation bin, and the slag precipitated at the bottom is difficult to be floated by the bubbles.

[0004] In order to solve the above problems, a flotation machine with announcement number CN118060078B is provided, which is equipped with components such as an annular electromagnet, a metal disk, a turntable and a pressure sensor. When the annular electromagnet is intermittently energized, the driven shaft will be reciprocated and lifted. When the driven shaft is reciprocated and lifted, the metal disk and the ring sleeve will vibrate, so that the bubbles adhered to the outer wall of the flotation tube will be detached, and the lifting of the turntable will cooperate with the circular disk to form bubbles of different sizes to achieve the effect of enhancing the flotation of the ore pulp.

[0005] However, when this equipment is in use, the scraper surface will always be attached with minerals when scraping the floating mineralized foam, resulting in the minerals remaining on the scraper surface cannot be effectively processed, requiring personnel to perform secondary recovery and processing, which affects the flotation efficiency of the minerals.

At the same time, the gas cylinder 520 drives the round rod 522 to rotate during the rotation process, so that the round rod 522 drives the support frame 523 to rotate, and the support frame 523 drives the rotating frame 524 and the knocking rod 525 to rotate. When the knocking rod 525 rotates to a position where it collides with the surface of the rectangular block 515, the knocking rod 525 rotates along the inner wall of the rotating frame 524 toward the direction close to the first spring 526, so that the rectangular block 515 drives the filter cover 513 to vibrate under the impact of the knocking rod 525, so that the minerals remaining on the surface of the filter cover 513 roll quickly to the guide plate 514 for discharge under the action of vibration and gas blowing, thereby completing the collection of minerals and the screening of water stains. The plate 514 is discharged into the round box 61. At this time, the hot air blower 62 is started to blow hot air into the round box 61, so that the hot air dries the surface of the mineral entering the round box 61. At the same time, the first gear shaft 528 drives the brush 68 and the rectangular rod 69 to rotate along the inside of the round box 61 during the rotation, so that the rectangular rod 69 drives the second gear shaft 610 to rotate. Under the action of the second gear shaft 610 meshing with the gear ring 63, the second gear shaft 610 rotates during the movement along the inside of the cylinder 512, so that the second gear shaft 610 drives the cross rod 613 and the multiple balls 614 to rotate, so that the multiple balls 614 rotate during the movement and grind the minerals inside the round box 61.At this time, the brush 68 rotates with the first gear shaft 528 to sweep the mineral into the inlet position of the discharge hole 66 and discharge it into the collection box 67 for storage, thereby completing the drying and secondary crushing of the mineral.
