Description

Technical Field

[0001] This invention relates to the field of mineral powder sorting technology, and in particular to a sorting device and method for magnetite powder. Background Technology

[0002] Currently, the most widely used magnetic separators in the mining industry are divided into wet magnetic separators and dry magnetic separators. Wet magnetic separators are widely used for separating materials such as clay minerals, relatively wet ores and slag. When wet high-intensity magnetic separators work in a water medium environment, the fluidity of the slurry makes the mineral powder easier to disperse, effectively avoiding the mineral powder agglomeration phenomenon commonly seen in dry separation. The presence of the water medium not only reduces the friction between mineral powders, but also reduces the weight of the mineral powders through buoyancy, making it easier for the mineral powders to be captured in the magnetic field.

[0003] In existing wet magnetic separators, concentrate and tailings are fed into the feed inlet for separation. Mineral powder is prone to sedimentation in water, especially weakly magnetic mineral powder. When weakly magnetic mineral powder passes through the strong magnetic screening section, it cannot be attracted by the strong magnet, causing some of the mineral powder to be lost with the water flow. When strongly magnetic mineral powder is covered by weakly magnetic mineral powder, it will also be unable to be attracted by the strong magnet, resulting in the loss of both strong and weakly magnetic mineral powder, leading to low magnetic separation efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of wet magnetic separators in completely separating concentrates, this invention provides a separation device and method for magnetite powder.

[0005] The technical solution is as follows: A magnetite powder sorting device includes a water storage tank, a shell fixedly connected to the water storage tank, a collection hopper fixedly connected to the side of the water storage tank, a discharge port at the bottom of the shell, a magnetic separator rotatably connected to the shell, and a support frame.

A T-shaped rod is slidably connected to the sorting plates, and a third elastic element is provided between the T-shaped rod and the sorting plates. The sliding plate contacts the T-shaped rod and provides movement for the T-shaped rod. A first rotating wheel is rotatably connected to the T-shaped rod.

[0009] Preferably, a baffle plate is slidably connected inside the screening barrel, and a first discharge port is opened on the baffle plate. A second discharge port is opened at the bottom of the screening barrel, and the first discharge port and the second discharge port correspond to each other. A slide rail is fixedly connected to the bottom of the screening barrel. The lower part of the floating barrel is fixedly connected to one end of the telescopic rod, and the other end of the telescopic rod is slidably inserted into the slide rail.

[0010] Preferably, a guide plate is fixedly attached to the outer shell, and an arc-shaped groove is provided at the lower part of the guide plate, with an arc-shaped plate slidably connected inside the arc-shaped groove of the guide plate.

[0011] Preferably, a baffle rod is symmetrically slidably connected to the inner wall of the outer shell, one end of the baffle rod is fixedly connected to the arc plate, and a fourth magnet is provided on the baffle rod.

[0012] Preferably, a dial is fixed to the end of the magnetic separator, and several levers are fixed to the dial. A shaped rod is slidably connected to the outer shell.

[0013] Preferably, a scraper is fixed to the outer casing, and the scraper contacts the magnetic separator.

[0014] A method for separating magnetite powder, applicable to the aforementioned magnetite powder separating device, includes the following steps: S1: Pour the mineral powder into the screening barrel through the feed port on the screening barrel, start the drive motor, and drive the output shaft of the drive motor to drive several sorting plates to rotate around the axis of the floating barrel. The sorting plates stir the mineral powder. The rotation of the floating barrel causes the slider to slide along the irregular track. The slider drives the floating barrel to move downward. When the slider slides to the bottom of the irregular track, it is released from the restriction of the irregular track. The floating barrel drives the sorting plate to slide upward quickly and reset through the first elastic element to impact the powder slurry in the screening barrel. S2: When the sorting plate rotates, the magnetic material in the slurry is adsorbed onto the first magnet. The convex shaft is squeezed by the guide rod and slides along the outer wall of the guide rod, which drives the scraper to move. The scraper gathers the magnetic material adsorbed on the sorting plate towards the floating bucket. The movement of the scraper drives the first rotating wheel to squeeze the blocking plate to rotate. Then the scraper pushes the magnetic material into the floating bucket. The magnetic material flows through the floating bucket to the inner wall of the outer shell. At the same time, the baffle plate rotates so that the slurry with more impurities flows through the guide pipe to the inner wall of the outer shell. S3: The slurry with more magnetic material flows along the inner wall of the shell to the arc plate. After the magnetic separator rotates, it attracts the magnetic material in the slurry to the scraper. S4: The slurry with more impurities flows along the inner wall of the shell to the baffle bar. The lever squeezes the second rotating wheel to make the baffle bar vibrate. The non-magnetic material blocked by the baffle bar is released from the baffle bar and falls into the water storage tank. The magnetic material gradually falls into the receiving box as the baffle bar vibrates.

[0015] The beneficial effects of this invention are: 1. This invention, through the cooperation of a floating bucket and a sorting plate, performs preliminary sorting of magnetic substances in the slurry while stirring it; through the cooperation of the floating bucket and the oscillation component, it further prevents the slurry from settling; the magnetic substances on the sorting plate are scraped off by the scraper, and the slurry with more magnetic substances is separated from the slurry with fewer magnetic substances, further improving the overall sorting efficiency of the device and effectively preventing the loss of mineral powder.

[0016] 2. The present invention, through the cooperation of the scraper and the sliding plate, keeps the baffle in a closed state when the scraper has not completely scraped off the magnetic material on the sorting plate, effectively preventing too much slurry from entering the floating tank, and further improving the separation effect of slurry with more magnetic material and slurry with less magnetic material.

[0017] 3. The present invention uses the cooperation between the lever and the second rotating wheel to make the baffle bar vibrate continuously, so that the magnetic material adsorbed on the baffle bar is detached from the baffle bar by the vibration force and enters the receiving box.

It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0021] like Figures 1-3 As shown, a magnetite powder sorting device includes a water storage tank 1, a housing 100 fixedly connected to the water storage tank 1, a hopper 200 for collecting magnetic materials fixedly connected to the side of the water storage tank 1, a discharge port 300 at the bottom of the housing 100, and a magnetic separator 400 rotatably connected to the housing 100. It also includes a support 201, with the support 201 fixedly connected to one side of the water storage tank 1. A primary sorting mechanism for preliminary sorting of the ore powder is installed on the support 201. The primary sorting mechanism separates most of the magnetic materials in the slurry. The primary sorting mechanism includes a screening barrel 202, which is fixedly connected to the support 201. The screening barrel 202 has a feed inlet, and a drive motor 203 is installed on the screening barrel 202. The output shaft of the drive motor 203 is connected to... One end of the telescopic shaft 204 is fixedly connected, and the other end of the telescopic shaft 204 is fixedly connected to a floating bucket 205. The floating bucket 205 passes through the screening bucket 202 and is rotatably connected. A oscillating component is provided on the lower side of the screening bucket 202 to provide movement for the floating bucket 205. The oscillating component effectively prevents the slurry in the screening bucket 202 from settling. Several sorting plates 206 are fixedly connected to the floating bucket 205. There are three groups of sorting plates 206, with three plates in each group. The three groups of sorting plates 206 are staggered. A first magnet 2061 is provided on the inclined surface of each sorting plate 206. A scraping mechanism for collecting magnetic materials is provided on the sorting plate 206. The scraping mechanism collects the magnetic materials adsorbed on the inclined surface of the sorting plate 206.

[0022] like Figures 1-3 As shown, the oscillation assembly includes a sleeve 301. The sleeve 301 is fixedly connected to the middle of the support 201. The sleeve 301 is sleeved on the lower part of the outer wall of the floating barrel 205. A convex ring 302 is rotatably connected to the lower part of the floating barrel 205. The convex ring 302 is located on the upper side of the sleeve 301. A first elastic element, which is a compression spring, is provided between the convex ring 302 and the sleeve 301.

[0023] like Figure 2 and 4As shown in Figure -5, the scraping mechanism includes a scraper 401. Each sorting plate 206 is slidably connected to a scraper 401. A convex shaft 402 is fixedly connected to the top of each scraper 401. A vertical track is opened inside the screening barrel 202. A ring 403 is slidably connected within the vertical track of the screening barrel 202. Three guide rods 404 are fixedly connected to the ring 403. When the convex shaft 402 moves, it contacts the guide rods 404 and slides along the outer wall of the guide rods 404. Each ring 403 is fixedly connected to a connecting frame 405, which is rotatably connected to the floating bucket 205. A chamfered rod 406 is fixedly connected to the top of the scraper 401. Each sorting plate 206 has a sliding groove 407 on its side wall. The chamfered rod 406 slides into the sliding groove 407 of the corresponding sorting plate 206. A second elastic element, which is a return spring, is provided between the chamfered rod 406 and the sliding groove 407 of the corresponding sorting plate 206.

[0024] like Figures 4-5 As shown, several sorting plates 206 are provided with inclined grooves, and sliding plates 501 are slidably connected in the inclined grooves of each sorting plate 206. When a scraper 401 moves, it contacts the sliding plate 501. The scraper 401 is used to provide movement for the sliding plate 501. T-shaped rods 502 are slidably connected to the top surface of the inner wall of each sorting plate 206. A third elastic element, which is a compression spring, is provided between the T-shaped rod 502 and the sorting plate 206. The sliding plate 501 contacts the adjacent T-shaped rod 502 and is used to squeeze the T-shaped rod 502 to move. The ends of the T-shaped rods 502 rotate. A first rotating wheel 503 is connected to a floating bucket 205, which has several irregularly shaped grooves 5031 extending through it. Several sorting plates 206 correspond to the irregularly shaped grooves 5031 of the floating bucket 205. Each sorting plate 206 is hinged with a baffle plate 504, which corresponds to the irregularly shaped grooves 5031 of the floating bucket 205. A fourth elastic element, which is a torsion spring, is provided between the baffle plate 504 and the sorting plate 206. The first rotating wheel 503 contacts the baffle plate 504 and is used to squeeze the baffle plate 504 to rotate.

[0025] like Figure 6 As shown, a baffle plate 601 is slidably connected to the bottom of the screening barrel 202. The baffle plate 601 has four first discharge ports 6011. The bottom of the screening barrel 202 has symmetrically arranged second discharge ports 6012. The first discharge ports 6011 and the second discharge ports 6012 correspond to each other. A slide rail 602 is fixedly connected to the bottom of the screening barrel 202. One end of a telescopic rod 603 is symmetrically fixedly connected to the lower part of the floating barrel 205. The other end of the telescopic rod 603 is slidably inserted into the slide rail 602. A second magnet 6031 is provided at the end of the telescopic rod 603 that is slidably inserted into the slide rail 602. A third magnet 6032 is provided on the baffle plate 601. The second magnet 6031 and the third magnet 6032 correspond to each other. A guide pipe 604 is symmetrically connected to the bottom of the screening barrel 202. The guide pipe 604 corresponds to the second discharge port 6012 of the screening barrel 202.

[0026] In existing technologies, when separating magnetite powder, the powder and water are thoroughly mixed using a stirring device, and then the mixed slurry is directly poured into a magnetic separator for separation. Due to the nature of the powder, it will quickly settle after mixing with water. The settled powder will prevent the concentrate in the magnetic separator 400 from being adsorbed by the separator, and the concentrate will be discharged with the tailings, resulting in low separation efficiency. This device can effectively solve the above problems.

[0027] Specifically: the slurry, a mixture of mineral powder and water, is poured into the screening tank 202 through the feed inlet. The drive motor 203 is started, and its output shaft drives the floating tank 205 to rotate via the telescopic shaft 204. The floating tank 205 then drives the sorting plates 206 to rotate, agitating the slurry within the screening tank 202. After rotation, most of the magnetic material in the slurry is adsorbed onto the first magnets 2061 of the sorting plates 206. Simultaneously, the floating tank 205 drives the slider 304 to slide along the irregular track 303, which in turn drives the floating tank 205 downwards. The floating tank 205, through the connecting frame 405, drives the ring 403 along the screening tank 202. As the trajectory of 2 slides downward, the ring 403 drives the guide rod 404 to slide downward. At this time, the first elastic element between the floating bucket 205 and the sleeve 301 is compressed by force. When the slider 304 slides to the bottom of the irregular track 303, the slider 304 is no longer restricted by the irregular track 303, allowing the floating bucket 205 to move. At this time, the floating bucket 205 releases through the first elastic element and slides upward to reset. The floating bucket 205 drives the sorting plate 206 to lift upward to reset. Several sorting plates 206 lift upward quickly, causing the slurry to float upward under force, preventing the mineral powder in the slurry from settling. At the same time, the floating bucket 205 drives the ring 403 through the connecting frame 405, causing the ring 403 to drive the guide rod 404 to move and reset.

[0028] Initially, the baffle plate 504 is kept blocked from the irregular groove 5031 by the fourth elastic element, and the slurry in the screening barrel 202 cannot flow into the irregular groove 5031 through the baffle 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, it drives the corresponding convex shaft 402 to contact the adjacent guide rod 404. After the convex shaft 402 moves, it is squeezed by the guide rod 404 and slides along the side wall of the guide rod 404, which drives the corresponding scraper 401 to slide. The scraper 401 drives the corresponding crisscross rod 406 to slide along the slide groove 407 of the corresponding sorting plate 206 towards the side closer to the floating barrel 205. The second crisscross rod 406 and the corresponding slide groove 407 are separated by a second crisscross rod. When the elastic element contracts under force, the scraper 401 slides and scrapes the magnetic material adsorbed on the inclined surface of the sorting plate 206 towards the side closer to the floating tank 205. After sliding, the scraper 401 contacts and presses against the sliding plate 501. The sliding plate 501 is forced to adhere to the scraper 401 and slides along the inclined groove of the sorting plate 206. When the scraper 401 scrapes the magnetic material off the inclined surface of the sorting plate 206, the magnetic material accumulates on the outer wall of the scraper 401. After the sliding plate 501 slides along the inclined groove of the sorting plate 206, it scrapes away the magnetic material on the outer wall of the scraper 401. Furthermore, after the sliding plate 501 moves, it presses against the T-shaped rod 502, causing the T-shaped rod 502 to move towards the side closer to the adjacent baffle plate 504. This causes the T-shaped rod 502 to drive the first rotating wheel 503 to press against the baffle plate 504. After the rod 502 moves, it compresses the adjacent third elastic element, causing the third elastic element to contract. The baffle plate 504, under pressure, rotates around the connection point of the sorting plate 206. The fourth elastic element between the baffle plate 504 and the sorting plate 206 is torn by force. After the baffle plate 504 rotates, it no longer blocks the irregular groove 5031 of the floating bucket 205. At this time, the scraped-off magnetic material, along with some slurry, enters the floating bucket 205 through the irregular groove 5031. After the convex shaft 402 continues to move, it no longer contacts the guide rod 404, allowing the adjacent scraper 401 to move. At this time, the convex rod 406 releases and slides back to its original position through the corresponding second elastic element, driving the corresponding scraper 401 to slide back to its original position. The scraper 401 drives the corresponding convex shaft 402 to reset, and the scraper 401 resets. After the pressure on the slide plate 501 ceases, the slide plate 501 no longer restricts the adjacent T-shaped rod 502. At this time, the T-shaped rod 502 releases through the corresponding third elastic element, causing the first rotating wheel 503 to reset and the adjacent slide plate 501 to reset. At this time, the blocking plate 504 is released from the restriction of the first rotating wheel 503. The blocking plate 504 is reset by twisting and rotating through the corresponding fourth elastic element. At this time, the slurry in the screening bucket 202 still contains a small amount of magnetic material. When the floating bucket 205 rotates, the floating bucket 205 drives the two telescopic rods 603 to rotate along the slide rail 602. The telescopic rods 603 extend and retract as the floating bucket 205 moves up and down. After the telescopic rods 603 rotate, they attract the third magnet 6032 through the second magnet 6031, causing the baffle plate 601 to rotate.When the first discharge port 6011 and the second discharge port 6012 on the baffle plate 601 coincide, the slurry in the screening tank 202 flows into the guide pipe 604 through the first discharge port 6011 and the second discharge port 6012, thereby completing the preliminary separation of magnetic substances in the slurry. The floating tank 205 and the guide pipe 604 then separate the slurry containing more magnetic substances from the slurry containing less magnetic substances.

[0029] like Figure 7 As shown, guide plates 701 are symmetrically fixed to the inner wall of the outer shell 100. The bottom end of the floating barrel 205 is located between the two guide plates 701. The bottom ends of the two guide pipes 604 are respectively located on the side of the two guide plates 701 away from the floating barrel 205. The lower part of the guide plates 701 is provided with arc-shaped grooves, and arc-shaped plates 702 are slidably connected in the arc-shaped grooves of the guide plates 701.

[0030] like Figure 7 As shown, baffle rods 703 are symmetrically slidably connected to the inner wall of the outer shell 100. The baffle rods 703 are distributed in a figure-eight shape. The ends of the baffle rods 703 that are close to each other are fixed to the arc plate 702. A fourth magnet 7031 is provided on each baffle rod 703.

[0031] like Figures 7-11 As shown, a dial 704 is fixedly connected to each end of the magnetic separator 400. Several levers 705 are fixedly connected to the dial 704. A shaped rod 706 is slidably connected to the outer shell 100. A fifth elastic element, which is a return spring, is provided between one end of the shaped rod 706 and the outer shell 100. A second rotating wheel 707 is rotatably connected to the shaped rod 706. When the lever 705 moves, it contacts the second rotating wheel 707. The lever 705 drives the shaped rod 706 to move by pressing the second rotating wheel 707. A limit frame 708 is fixedly connected to the other end of the shaped rod 706. A rectangular groove is opened through the side of the outer shell 100. A protruding shaft is fixedly connected to the end of the baffle rod 703 away from the arc plate 702. The protruding shaft of the baffle rod 703 slides through the rectangular groove of the outer shell 100 and slides into the adjacent limit frame 708. A receiving box 709 is symmetrically fixed to the side of the water storage tank 1.

[0032] like Figure 9 As shown, a scraper 801 is fixedly attached to the outer casing 100. The scraper 801 is in contact with the magnetic separator 400 and is used to scrape off magnetic materials from the surface of the magnetic separator 400.

[0033] A method for separating magnetite powder using a sorting device includes the following steps: S1: The mineral 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 several sorting plates 206 to rotate around the axis of the floating barrel 205. The sorting plates 206 stir the mineral powder. The floating barrel 205 rotates, causing the slider 304 to slide along the irregular track 303. The slider 304 drives the floating barrel 205 to move downward. When the slider 304 slides to the bottom of the irregular track 303, it is released from the restriction of the irregular track 303. The floating barrel 205 drives the sorting plate 206 to slide upward and reset quickly through the first elastic element, impacting the powder slurry in the screening barrel 202. S2: When the sorting plate 206 rotates, the magnetic material in the slurry is adsorbed onto the first magnet 2061. The convex shaft 402 is squeezed by the guide rod 404 and slides along the outer wall of the guide rod 404, which drives the scraper 401 to move. The scraper 401 gathers the magnetic material adsorbed on the sorting plate 206 towards the floating bucket 205. The movement of the scraper 401 drives the first rotating wheel 503 to squeeze the blocking plate 504 to rotate. Then the scraper 401 pushes the magnetic material into the floating bucket 205. The magnetic material flows through the floating bucket 205 to the inner wall of the outer shell 100. At the same time, the baffle plate 601 rotates so that the slurry with more impurities flows through the guide pipe 604 to the inner wall of the outer shell 100. S3: The slurry with more magnetic material flows along the inner wall of the outer shell 100 to the arc plate 702. After the magnetic separator 400 rotates, it adsorbs the magnetic material in the slurry to the scraper 801. S4: The slurry with more impurities flows along the inner wall of the outer shell 100 to the baffle rod 703. The lever 705 causes the baffle rod 703 to vibrate by squeezing the second rotating wheel 707. The non-magnetic material blocked by the baffle rod 703 is released from the baffle rod 703 and falls into the water storage tank 1. The magnetic material gradually falls into the receiving box 709 as the baffle rod 703 vibrates.

[0034] The slurry containing more magnetic material enters the floating tank 205 and flows into the outer shell 100. The slurry containing more magnetic material flows between the two guide plates 701, while the slurry containing less magnetic material enters the guide pipe 604 and flows into the outer shell 100. The slurry containing less magnetic material flows on the side of the two guide plates 701 that are far apart from each other. The two guide plates 701 separate the slurry containing more magnetic material from the slurry containing less magnetic material, preventing them from mixing. When the slurry containing more magnetic material flows to the arc plate 702, it passes over the arc plate 702 and continues to flow. Because the gap between the arc plate 702 and the magnetic separator 400 is small, the flow speed of the slurry containing more magnetic material is slowed down by the arc plate 702. This allows the magnetic material in the slurry to fully contact the magnetic separator 400, improving the separation efficiency of the magnetic separator 400.

[0035] When the slurry containing less magnetic material flows to the baffle bar 703, the slurry is blocked by the baffle bar 703 and flows along the outer wall of the baffle bar 703. The magnetic material in the lower layer of the slurry is attracted to the surface of the baffle bar 703 by the fourth magnet 7031 on the baffle bar 703. The magnetic material is also carried by the slurry to the side of the baffle bar 703 near the outer shell 100. The remaining slurry flows past the top of the baffle bar 703 and continues to flow. The distance between the mineral powder in the slurry and the magnetic separator 400 is shortened, and the magnetic separator 400 more effectively adsorbs the concentrate in the slurry. The non-magnetic material falls into the water storage tank 1 through the discharge port 300 at the bottom of the outer shell 100 as the slurry flows. The magnetic material rotates with the surface of the magnetic separator 400 to the scraper bar 801. The scraper bar 801 scrapes the concentrate on the surface of the magnetic separator 400 into the collection hopper 200.

[0036] Initially, the two ends of the baffle rod 703 respectively block the two rectangular slots on the outer casing 100. As the magnetic separator 400 rotates, it drives the two dials 704 to rotate. The dials 704 respectively drive the corresponding levers 705 to rotate. After rotating, the levers 705 contact and press against the adjacent second rotating wheel 707. The second rotating wheel 707, after being pressed, drives the corresponding irregular rod 706 to move to the right. The movement of the irregular rod 706 presses against the corresponding fifth elastic element, causing it to contract. Furthermore, the irregular rod 706 drives the corresponding limiting frame 708 to move. The moving limiting frame 708 presses against the protruding shaft of the corresponding baffle rod 703, causing the protruding shaft of the baffle rod 703 to slide along the limiting frame 708. The force on the baffle rod 703 causes the arc plate 702 to slide along the inner wall of the outer casing 100. After sliding, the baffle rod 703 does not... After the rectangular groove of the outer casing 100 is blocked again, the lever 705 continues to rotate and no longer contacts the second rotating wheel 707. After the second rotating wheel 707 is released from the restriction, the corresponding irregular rod 706 can move. The irregular rod 706 releases and slides quickly to reset through the corresponding fifth elastic element and generates oscillation. After the irregular rod 706 is reset, it squeezes the protruding shaft of the baffle rod 703 through the limit frame 708, causing the baffle rod 703 and the arc plate 702 to reset quickly and generate oscillation. The baffle rod 703 uses the oscillation force to gather the magnetic material adsorbed on the surface of the baffle rod 703 to the rectangular grooves on both sides of the outer casing 100, and discharges through the rectangular grooves on both sides of the outer casing 100 into the receiving box 709. The baffle rod 703 sorts the slurry with less magnetic material, which greatly improves the sorting efficiency of the overall device.

10. A method for separating magnetite powder, the method being applicable to the magnetite powder separating apparatus described in claim 9, characterized in that, Includes the following steps: S1: The mineral 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 several sorting plates (206) to rotate around the axis of the floating barrel (205). The sorting plates (206) stir the mineral powder. The floating barrel (205) rotates and causes the slider (304) to slide along the irregular track (303). The slider (304) drives the floating barrel (205) to move downward. When the slider (304) slides to the bottom of the irregular track (303), it is released from the restriction of the irregular track (303). The floating barrel (205) drives the sorting plate (206) to slide upward quickly and reset through the first elastic element to impact the powder slurry in the screening barrel (202). S2: When the sorting plate (206) rotates, the magnetic material in the slurry is adsorbed onto the first magnet (2061). The convex shaft (402) is squeezed by the guide rod (404) and slides along the outer wall of the guide rod (404) and drives the scraper (401) to move. The scraper (401) gathers the magnetic material adsorbed on the sorting plate (206) towards the floating bucket (205). The movement of the scraper (401) drives the first rotating wheel (503) to squeeze the blocking plate (504) to rotate. Then the scraper (401) pushes the magnetic material into the floating bucket (205). The magnetic material flows through the floating bucket (205) to the inner wall of the outer shell (100). At the same time, the baffle plate (601) rotates so that the slurry with more impurities flows through the guide pipe (604) to the inner wall of the outer shell (100). S3: The slurry with more magnetic material flows along the inner wall of the outer shell (100) to the arc plate (702). After the magnetic separator (400) rotates, it adsorbs the magnetic material in the slurry to the scraper (801). S4: The slurry with more impurities flows along the inner wall of the outer shell (100) to the baffle bar (703). The lever (705) squeezes the second rotating wheel (707) to make the baffle bar (703) vibrate. The non-magnetic material blocked by the baffle bar (703) leaves the baffle bar (703) and falls into the water storage tank (1). The magnetic material gradually falls into the receiving box (709) as the baffle bar (703) vibrates.
