Description

TECHNICAL FIELD

[0002] At present, the most widely used magnetic separator in the mining industry is divided into wet magnetic separator and dry magnetic separator. The wet magnetic separator is widely used in sorting of sticky minerals, relatively wet ores and slag and other materials. When the wet high-intensity magnetic separator works in the water medium environment, the fluidity of the ore pulp makes the ore powder more easily dispersed, effectively avoiding the ore powder agglomeration phenomenon often seen in dry sorting. The presence of water medium not only reduces the friction between the ore powder, but also reduces the weight of the ore powder through the buoyancy effect, so that the ore powder is more easily captured in the magnetic field.

[0003] In the prior art, the wet magnetic separator in the process of use, the concentrate and the tailings are uniformly fed into the feed inlet for sorting. The ore powder is prone to sedimentation in water, especially when the weak magnetic ore powder passes through the strong magnetic screening position. The weak magnetic ore powder cannot be adsorbed by the strong magnet, resulting in the loss of part of the ore powder along with the flow of water. When the strong magnetic ore powder is covered by the weak magnetic ore powder, the strong magnetic ore powder cannot be adsorbed by the strong magnet, resulting in the loss of the strong magnetic ore powder together with the weak magnetic ore powder, and the low magnetic separation efficiency.

[0041] In the prior art, when magnetite powder is sorted, the magnetite powder is fully stirred with water by a stirring device, and then the mixed slurry is directly poured into a magnetic separator for sorting. Due to the material of the magnetite powder, the magnetite powder will quickly precipitate after being mixed and stirred with water, and the precipitated magnetite powder will cause the concentrate in the magnetite powder to be unable to be adsorbed by the magnetic separation cylinder 400 when the magnetite powder passes through the magnetic separation cylinder 400, and the concentrate will be discharged with the tailings, resulting in low sorting efficiency. The device can effectively solve the above problems.

[0042] Specifically: the slurry obtained by mixing the magnetite powder with water is poured into the screening barrel 202 through the feed inlet on the screening barrel 202, the driving motor 203 is started, the output shaft of the driving motor 203 drives the floating barrel 205 to rotate through the telescopic shaft 204, the floating barrel 205 drives the sorting plate 206 to rotate, the sorting plate 206 stirs the slurry in the screening barrel 202, most of the magnetic substances in the slurry are adsorbed on the first magnet 2061 of the sorting plate 206 after the sorting plate 206 rotates, at the same time, the floating barrel 205 drives the sliding block 304 to slide along the special-shaped track 303, the sliding block 304 drives the floating barrel 205 to slide downward, the floating barrel 205 drives the circular ring 403 to slide downward along the track of the screening barrel 202 through the connecting frame 405, the circular ring 403 drives the guide rod 404 to slide downward, at this time, the first elastic member between the floating barrel 205 and the sleeve 301 is contracted under stress, when the sliding block 304 slides to the bottom of the special-shaped track 303, the floating barrel 205 can move because the sliding block 304 is no longer limited by the special-shaped track 303, at this time, the floating barrel 205 is quickly upwardly reset by the first elastic member, the floating barrel 205 drives the sorting plate 206 to quickly upwardly reset, the sorting plate 206 makes the slurry upwardly float under stress by quickly upwardly lifting, so as to prevent the magnetite powder in the slurry from precipitating, at the same time, the floating barrel 205 drives the circular ring 403 to move the guide rod 404 to reset through the connecting frame 405.

[0043] At the beginning, the blocking plate 504 is kept closed to the special-shaped groove 5031 by the fourth elastic member, and the slurry in the screening barrel 202 cannot flow into the special-shaped groove 5031 through the blocking plate 504. When the sorting plate 206 rotates, the sorting plate 206 drives the corresponding scraper 401 to rotate around the axial direction of the screening barrel 202. When the scraper 401 rotates, the corresponding convex shaft 402 is in contact with the adjacent guide rod 404. After the convex shaft 402 moves, it is extruded by the guide rod 404 and slides along the side wall of the guide rod 404, and drives the corresponding scraper 401 to slide. The scraper 401 drives the corresponding L-shaped rod 406 to slide along the sliding groove 407 of the corresponding sorting plate 206 to the side close to the floating barrel 205. The second elastic member between the L-shaped rod 406 and the corresponding sliding groove 407 is contracted under stress. After the scraper 401 slides, the magnetic material adsorbed on the inclined surface of the sorting plate 206 is scraped to the side close to the floating barrel 205. After the scraper 401 slides, it is in contact with and extrudes the sliding plate 501. The sliding plate 501 is in contact with the scraper 401 under stress and slides along the inclined groove of the sorting plate 206. When the magnetic material on the inclined surface of the sorting plate 206 is scraped off by the scraper 401, the magnetic material will accumulate on the outer wall of the scraper 401. After the sliding plate 501 slides along the inclined groove of the sorting plate 206, the magnetic material on the outer wall of the scraper 401 is scraped off. After the sliding plate 501 moves, it extrudes the T-shaped rod 502, so that the T-shaped rod 502 moves to the side close to the adjacent blocking plate 504. The T-shaped rod 502 drives the first rotating wheel 503 to extrude the blocking plate 504. After the T-shaped rod 502 moves, it extrudes the adjacent third elastic member, so that the third elastic member is contracted. After the blocking plate 504 is extruded, it rotates around the connection of the sorting plate 206. The fourth elastic member between the blocking plate 504 and the sorting plate 206 is twisted under stress. After the blocking plate 504 rotates, it no longer blocks the special-shaped groove 5031 of the floating barrel 205. At this time, the scraped magnetic material and part of the slurry enter the floating barrel 205 through the special-shaped groove 5031. After the convex shaft 402 continues to move, it is no longer in contact with the guide rod 404, so that the adjacent scraper 401 can move. At this time, the L-shaped rod 406 releases the sliding reset through the corresponding second elastic member and drives the corresponding scraper 401 to slide reset. The scraper 401 drives the corresponding convex shaft 402 to reset. After the scraper 401 resets, it no longer extrudes the sliding plate 501. The sliding plate 501 no longer limits the adjacent T-shaped rod 502. At this time, the T-shaped rod 502 releases the first rotating wheel 503 through the corresponding third elastic member and drives the first rotating wheel 503 to reset and drives the adjacent sliding plate 501 to reset. At this time, the blocking plate 504 is released from the limitation of the first rotating wheel 503. The blocking plate 504 rotates and resets through the corresponding fourth elastic member. At this time, the slurry in the screening barrel 202 still contains a small amount of magnetic material. When the floating barrel 205 rotates, the floating barrel 205 drives the two telescopic rods 603 to rotate along the sliding rail 602. The telescopic rod 603 telescopes with the floating barrel 205 moving up and down. After the telescopic rod 603 rotates, it drives the baffle plate 601 to rotate through the second magnet 6031 attracting the third magnet 6032.When the first discharge port 6011 and the second discharge port 6012 on the material blocking disc 601 coincide, the slurry in the screening barrel 202 flows into the flow guide pipe 604 through the first discharge port 6011 and the second discharge port 6012, thereby completing the preliminary separation of the magnetic substances in the slurry, and separating the slurry containing more magnetic substances from the slurry containing less magnetic substances through the floating barrel 205 and the flow guide pipe 604.

[0048] A sorting method of a magnetite powder sorting device, comprising the following steps:

[0049] S1: The ore powder is poured into the screening barrel 202 through the feed port on the screening barrel 202, the drive motor 203 is started, the output shaft of the drive motor 203 drives a plurality of sorting plates 206 to rotate around the axis of the floating barrel 205, the sorting plates 206 stir the ore powder, the floating barrel 205 rotates to make the sliding block 304 slide along the special-shaped rail 303, the sliding block 304 drives the floating barrel 205 to move downward, when the sliding block 304 slides to the bottom of the special-shaped rail 303, it is separated from the special-shaped rail 303, the floating barrel 205 drives the sorting plates 206 to slide upward quickly and reset to impact the slurry in the screening barrel 202 through the first elastic member;

[0050] S2: When the sorting plate 206 rotates, the magnetic material in the slurry is adsorbed on the first magnet 2061, the convex shaft 402 is pressed along the outer wall of the guide rod 404 and drives the scraper 401 to move, the scraper 401 converges the magnetic material adsorbed on the sorting plate 206 to the floating barrel 205, the movement of the scraper 401 drives the first rotating wheel 503 to press and block the rotating plate 504, then the scraper 401 pushes the magnetic material into the floating barrel 205, the magnetic material flows to the inner wall of the shell 100 through the floating barrel 205, and at the same time, the blocking disc 601 rotates to make the slurry with more impurities flow to the inner wall of the shell 100 through the flow guide pipe 604;

[0054] When the slurry containing less magnetic material flows to the material blocking rod 703, the slurry is blocked by the material blocking rod 703 and flows along the outer wall of the material blocking rod 703, the magnetic material in the lower layer of the slurry is adsorbed on the surface of the material blocking rod 703 by the fourth magnet 7031 on the material blocking rod 703, and the magnetic material is washed by the slurry and flows to the side of the material blocking rod 703 close to the shell 100, the remaining slurry flows over the top end of the material blocking rod 703 and continues to flow, the distance between the ore powder in the slurry and the magnetic separation cylinder 400 is shortened, the magnetic separation cylinder 400 more effectively adsorbs the concentrate in the slurry, the non-magnetic material flows with the slurry through the material throwing port 300 at the bottom of the shell 100 and falls into the water storage tank 1, and the magnetic material rotates to the scraping rod 801 on the surface of the magnetic separation cylinder 400, and the scraping rod 801 scrapes the concentrate on the surface of the magnetic separation cylinder 400 and falls into the material collecting hopper 200.
