[0018] A magnetic separation and iron removal method of a potassium feldspar ball mill magnetic separation and iron removal device, comprising the following steps:

[0019] S1, conveying the potassium feldspar ball mill material through the feeding belt;

[0020] S2, starting the rotating mechanism, so that the fourth motor drives the first gear to rotate, and then the first gear drives the fixed roller to rotate through the second gear, so that the fixed roller drives each receiving drum to rotate circularly through the U-shaped frame, when the material moves to the tail end of the feeding belt, the opening of one of the receiving drums is turned upward to below the tail end of the feeding belt, so that the material can fall into the receiving drum;

[0021] S3, after the material falls into the receiving drum, start the fifth motor, so that the fifth motor drives the connecting handle to rotate, and then the connecting handle drives the arc-shaped cover plate to slide through the convex strip, so that the arc-shaped cover plate slides along the limiting groove through the limiting block, thereby controlling the arc-shaped cover plate to close the opening of the receiving drum, so that the material cannot fall out of it;

[0022] S4, then the receiving drum drives the material to continue to rotate, and by starting the sixth motor, the sixth motor drives the connecting shaft to rotate, and then the connecting shaft drives each stirring blade to rotate, so that the stirring blades can beat and collide with the material while the material is rotating and surging, so as to further scatter the material, thereby preventing the material from clumping and adhering, greatly ensuring the subsequent magnetic separation and iron removal effect;

[0023] S5, when the receiving drum drives the material to rotate above the receiving frame, at this time the opening of the receiving drum is downward, by controlling the fifth motor to drive the connecting handle to rotate in a direction, the arc-shaped cover plate can slide and open the opening, so that the material in the receiving drum can fall out and fall on the receiving frame, and by the circular rotation of the multiple groups of receiving drums, continuous and uniform intermittent receiving and discharging can be realized, effectively preventing the material from accumulating and congesting, so that the material can fully contact with the magnetic cylinder, greatly improving the magnetic separation effect;

[0024] S6. Then the material can flow along the receiving frame to the magnetic drum. During the flow, the third motor can be started, which drives the two synchronous pulleys to rotate through the synchronous belt. Then the two threaded rods drive the movable block to move in the mounting frame. This allows the movable block to drive the scraper to move back and forth above the receiving frame. By having two sets of scrapers staggered, the material flowing on the receiving frame can be scraped flat, which further prevents the material from clogging or piling up in one place. This makes the material flowing to the magnetic drum more evenly distributed, greatly improving the fineness of magnetic separation.

[0025] S7. The material is then evenly sprinkled onto the magnetic cylinder, and the second pulley is driven to rotate by the first motor. The second pulley drives the first pulley to rotate via a belt, which in turn drives the magnetic cylinder to rotate. The magnetic cylinder can adsorb iron particles in the material, while the material without iron particles can continue to fall onto the feeding belt. As the magnetic cylinder rotates, the iron particles are scraped off by the abutment plate and fall onto the feeding frame. At the same time, the second motor drives the rotating roller to rotate, which in turn drives the brush plate to rotate. The brush plate then further sweeps down the iron particles accumulated between the abutment plate and the magnetic cylinder, thereby achieving efficient magnetic separation and iron removal in potassium feldspar ball milling.

[0026] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0027] By setting up a receiving mechanism and a conveying mechanism between the feeding assembly and the magnetic cylinder, the receiving mechanism consists of a fixed roller, multiple receiving rollers, a rotating mechanism, and a sliding mechanism. This allows the material on the feeding belt to continuously fall into each receiving roller. The multiple receiving rollers rotate in a cycle and send the material to the conveying mechanism, which then sends the material to the magnetic cylinder. This enables continuous and uniform intermittent receiving and discharging, effectively preventing the accumulation and blockage of a large amount of material. It also allows the material to fully contact the magnetic cylinder, greatly improving the magnetic separation effect.

[0028] Meanwhile, the material conveying mechanism consists of a baffle, a receiving frame, and a distributing mechanism. The receiving frame can throw the material onto the surface of the magnetic drum, and the distributing mechanism can scrape the material flowing on the receiving frame to level it, thereby further preventing the material from clogging or piling up in one place, making the material flowing to the magnetic drum more evenly distributed, and greatly improving the fineness of magnetic separation.

[0029] By setting an arc-shaped cover plate and a sliding mechanism at the open end inside the receiving roller, the arc-shaped cover plate can slide on the surface of the receiving roller, thereby controlling the arc-shaped cover plate to close the opening of the receiving roller, preventing the material from falling out. When receiving material, the arc-shaped cover plate can be controlled again to open the opening of the receiving roller to ensure normal material receiving.

[0030] By setting up a stirring mechanism inside the receiving drum, the material can be tumbled and rolled as the receiving drum rotates, while the stirring blades beat and collide with the material to further disperse it, thereby preventing the material from clumping and sticking together, and greatly ensuring the subsequent magnetic separation and iron removal effect.

[0049] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0050] This invention provides, for example Figures 1-15 The potassium feldspar ball mill magnetic separation iron removal device shown includes:

[0051] A fixed base 3 is provided, with a fixed frame 25 fixed at one end of the fixed base 3. The other end of the inner side of the fixed base 3 is rotatably connected to a magnetic cylinder 4 via a rotating shaft. The output end of the magnetic cylinder 4 is connected to a drive mechanism. A feeding frame 23 is provided on one side of the fixed base 3 near the magnetic cylinder 4. A stop plate 24 is provided on the top side of the feeding frame 23. The top of the stop plate 24 abuts against the outer wall of the magnetic cylinder 4. Arc-shaped baffles 5 are symmetrically connected to both ends of the top side of the stop plate 24 at the magnetic cylinder 4. A cleaning mechanism is provided above the feeding frame 23.

[0052] The drive mechanism includes a first motor 6 fixed to the outside of the fixed base 3, a first pulley 7 fixed to the output end of the magnetic cylinder 4, a second pulley 8 fixed to the output end of the first motor 6, and a belt 9 sleeved between the first pulley 7 and the second pulley 8.

[0053] The cleaning mechanism includes a cleaning frame 10 fixed on a fixed base 3. A second motor 13 is fixed to one end of the cleaning frame 10, and a rotating roller 11 is rotatably connected inside the cleaning frame 10. One end of the rotating roller 11 is connected to the second motor 13, and multiple brush plates 12 are arranged in a ring array on the outer wall of the rotating roller 11.

[0054] The receiving mechanism includes a fixed roller 26 rotatably connected to the top of the fixed frame 25 via bearings. U-shaped frames 27 are fixed at all four ends of the outer wall of the fixed roller 26, and a rotating mechanism is provided at one end of the fixed roller 26. A receiving roller 28 is connected to the end of the U-shaped frame 27. An arc-shaped cover plate 29 is slidably connected to the open end of the outer wall of the receiving roller 28. A sliding mechanism is provided between the arc-shaped cover plate 29 and the receiving roller 28. A stirring mechanism is provided inside the receiving roller 28.

[0055] The rotating mechanism includes a fourth motor 30 fixed to one side of the fixed frame 25. The output end of the fourth motor 30 is connected to a first gear 31, and the output end of the fixed roller 26 is connected to a second gear 32, and the second gear 32 meshes with the first gear 31.

[0056] The rotation mechanism is started, causing the fourth motor 30 to drive the first gear 31 to rotate. Then, the first gear 31 drives the fixed roller 26 to rotate through the second gear 32. The fixed roller 26 drives each receiving roller 28 to rotate cyclically through the U-shaped frame 27. When the material moves to the end of the feeding belt 1, the opening of one of the receiving rollers 28 rotates to face the bottom of the end of the feeding belt 1, so that the material can fall into the receiving roller 28.

[0057] The sliding mechanism includes a fifth motor 35 fixedly connected to one end of the receiving roller 28. The output end of the fifth motor 35 is connected to a connecting handle 36. One end of the arc-shaped cover plate 29 is fixed with a protrusion 37. The end of the connecting handle 36 is fixedly connected to the protrusion 37. A limiting component is provided between the arc-shaped cover plate 29 and the receiving roller 28.

[0058] The limiting assembly includes a limiting block 33 symmetrically fixed to one end of the inner side of the arc-shaped cover plate 29, and a limiting groove 34 matching the limiting block 33 is provided on the outer side of the receiving roller 28.

[0059] When the material falls into the receiving roller 28, the fifth motor 35 is started, which drives the connecting handle 36 to rotate. Then, the connecting handle 36 drives the arc-shaped cover plate 29 to slide through the protrusion 37. The arc-shaped cover plate 29 slides along the limiting groove 34 through the limiting block 33, thereby controlling the arc-shaped cover plate 29 to close the opening of the receiving roller 28, so that the material cannot fall out.

[0060] The mixing mechanism includes a sixth motor 38 fixed at one end of the receiving drum 28 relative to the fifth motor 35. The output end of the sixth motor 38 extends into the receiving drum 28 and is connected to a connecting shaft 39. The outer wall of the connecting shaft 39 is provided with a plurality of mixing blades 40.

[0061] Then the receiving drum 28 drives the material to continue rotating, and by starting the sixth motor 38, the sixth motor 38 can drive the connecting shaft 39 to rotate. Then the connecting shaft 39 drives each stirring blade 40 to rotate, so that while the material is rotating and churning, the stirring blade 40 can beat and collide with the material to further disperse the material, thereby preventing the material from clumping and sticking together, and greatly ensuring the subsequent magnetic separation and iron removal effect.

[0062] When the receiving roller 28 rotates the material to the top of the receiving frame 14, the opening of the receiving roller 28 faces downward. By controlling the fifth motor 35 to drive the connecting handle 36 to rotate, the arc-shaped cover plate 29 can slide and open the opening, allowing the material in the receiving roller 28 to fall out and onto the receiving frame 14. Through the cyclic rotation of multiple sets of receiving rollers 28, continuous and uniform intermittent receiving and discharging can be achieved, effectively preventing the large accumulation and blockage of materials, and allowing the material to fully contact the magnetic cylinder 4, greatly improving the magnetic separation effect.

[0063] The material transfer mechanism includes a baffle 41 fixed in the fixed base 3 near the magnetic cylinder 4. The top of the baffle 41 is connected to a receiving frame 14. The receiving frame 14 is inclined upward and the top of the receiving frame 14 is located below the receiving roller 28. A material distribution mechanism is provided inside the receiving frame 14.

[0064] The material distribution mechanism includes two mounting brackets 15 symmetrically fixed inside the receiving frame 14. The interior of each mounting bracket 15 is rotatably connected to a threaded rod 16 via bearings. The opposite ends of the two threaded rods 16 are symmetrically provided with movable blocks 17 via threads. The bottom end of the movable block 17 is connected to a scraper 19 near the top of the receiving frame 14. One end of each of the two threaded rods 16 is fixed with a synchronous pulley 20. A third motor 22 is provided on the outside of the receiving frame 14. The output end of the third motor 22 is connected to one of the synchronous pulleys 20, and a synchronous belt 21 is sleeved between the two synchronous pulleys 20.

[0065] The top side of the mounting bracket 15 is provided with a guide groove 18, and the top of the movable block 17 is slidably fitted in the guide groove 18.

[0066] The material can flow from the receiving frame 14 to the magnetic cylinder 4. During the flow, the third motor 22 can be started, which drives the two synchronous pulleys 20 to rotate via the synchronous belt 21. Then, the two threaded rods 16 drive the movable block 17 to move within the mounting frame 15. This allows the movable block 17 to drive the scraper 19 to move back and forth above the receiving frame 14. By having two sets of scrapers 19 staggered, the material flowing on the receiving frame 14 can be scraped flat, thereby further preventing material blockage or accumulation in one place. This makes the material flowing to the magnetic cylinder 4 more evenly distributed, greatly improving the fineness of magnetic separation.

[0067] The material is then evenly spread onto the magnetic cylinder 4, and the second pulley 8 is driven to rotate by the first motor 6. The second pulley 8 drives the first pulley 7 to rotate via the belt 9, which in turn drives the magnetic cylinder 4 to rotate. The magnetic cylinder 4 can adsorb iron in the material, while the material without iron can continue to fall onto the feeding belt 2. As the magnetic cylinder 4 rotates, the iron is scraped off the abutment plate 24 and onto the feeding frame 23. At the same time, the second motor 13 drives the rotating roller 11 to rotate, which in turn drives the brush plate 12 to rotate. The brush plate 12 then further sweeps down the iron that has accumulated between the abutment plate 24 and the magnetic cylinder 4, thereby achieving efficient magnetic separation and iron removal in potassium feldspar ball milling.

[0068] The material conveying assembly includes an upper feeding belt 1 and an lower feeding belt 2. The upper feeding belt 1 is located above the receiving roller 28, and the lower feeding belt 2 is located below the magnetic cylinder 4 and the baffle 41.

[0069] The feeding belt 1 conveys the potassium feldspar ball mill material, while the unloading belt 2 conveys the potassium feldspar ball mill material after iron removal.

[0070] refer to Figures 1-15 As shown, a magnetic separation method for removing iron from a potassium feldspar ball mill magnetic separation device is characterized by comprising the following steps:

[0071] S1. The potassium feldspar ball mill material is conveyed through the feeding belt 1;

[0072] S2. Start the rotating mechanism to make the fourth motor 30 drive the first gear 31 to rotate. Then the first gear 31 drives the fixed roller 26 to rotate through the second gear 32. The fixed roller 26 drives each receiving roller 28 to rotate cyclically through the U-shaped frame 27. When the material moves to the end of the feeding belt 1, the opening of one of the receiving rollers 28 rotates upward to the bottom of the end of the feeding belt 1, so that the material can fall into the receiving roller 28.

[0073] S3. When the material falls into the receiving roller 28, the fifth motor 35 is started, which drives the connecting handle 36 to rotate. Then the connecting handle 36 drives the arc-shaped cover plate 29 to slide through the protrusion 37. The arc-shaped cover plate 29 slides along the limiting groove 34 through the limiting block 33, thereby controlling the arc-shaped cover plate 29 to close the opening of the receiving roller 28, so that the material cannot fall out of it.

[0074] S4. Then the receiving drum 28 drives the material to continue rotating, and by starting the sixth motor 38, the sixth motor 38 can drive the connecting shaft 39 to rotate. Then the connecting shaft 39 drives each stirring blade 40 to rotate, so that while the material is rotating and churning, the stirring blade 40 can beat and collide with the material to further disperse the material, thereby preventing the material from clumping and sticking together, and greatly ensuring the subsequent magnetic separation and iron removal effect.

[0075] S5. When the receiving roller 28 rotates the material to the top of the receiving frame 14, the opening of the receiving roller 28 faces downward. By controlling the fifth motor 35 to drive the connecting handle 36 to rotate, the arc-shaped cover plate 29 can slide and open the opening, so that the material in the receiving roller 28 can fall out and land on the receiving frame 14. Through the cyclic rotation of multiple sets of receiving rollers 28, continuous and uniform intermittent receiving and unloading can be achieved, effectively preventing the material from accumulating and clogging, and allowing the material to fully contact the magnetic cylinder 4, which greatly improves the magnetic separation effect.

[0076] S6. Then the material can flow along the receiving frame 14 to the magnetic cylinder 4. During the flow, the third motor 22 can be started, which drives the two synchronous pulleys 20 to rotate through the synchronous belt 21. Then the two threaded rods 16 drive the movable block 17 to move within the mounting frame 15. This allows the movable block 17 to drive the scraper 19 to move back and forth above the receiving frame 14. By having two sets of scrapers 19 staggered, the material flowing on the receiving frame 14 can be scraped flat, thereby further preventing material blockage or accumulation in one place. This makes the material flowing to the magnetic cylinder 4 more evenly distributed, greatly improving the fineness of magnetic separation.

[0077] S7. The material is then evenly sprinkled onto the magnetic cylinder 4, and the second pulley 8 is driven to rotate by the first motor 6. The second pulley 8 drives the first pulley 7 to rotate via the belt 9, which in turn drives the magnetic cylinder 4 to rotate. The magnetic cylinder 4 can adsorb the iron material in the material, while the material without iron can continue to fall onto the feeding belt 2. As the magnetic cylinder 4 rotates, the iron material is scraped off the abutment plate 24 and onto the feeding frame 23. At the same time, the second motor 13 drives the rotating roller 11 to rotate, which in turn drives the brush plate 12 to rotate. The brush plate 12 then further sweeps down the iron material that has accumulated between the abutment plate 24 and the magnetic cylinder 4, thereby achieving efficient magnetic separation and iron removal in potassium feldspar ball milling.

[0078] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

6. The magnetic separation method for removing iron from a potassium feldspar ball mill magnetic separation device according to any one of claims 1-5, characterized in that, Includes the following steps: S1. The potassium feldspar ball mill material is conveyed by the feeding belt (1); S2. Start the rotating mechanism so that the fourth motor (30) drives the first gear (31) to rotate. Then the first gear (31) drives the fixed roller (26) to rotate through the second gear (32). The fixed roller (26) drives each receiving roller (28) to rotate in a cycle through the U-shaped frame (27). When the material moves to the end of the feeding belt (1), the opening of one of the receiving rollers (28) rotates upward to the bottom of the end of the feeding belt (1), so that the material can fall into the receiving roller (28). S3. When the material falls into the receiving roller (28), the fifth motor (35) is started, which drives the connecting handle (36) to rotate. Then the connecting handle (36) drives the arc-shaped cover plate (29) to slide through the protrusion (37). The arc-shaped cover plate (29) slides along the limiting groove (34) through the limiting block (33), thereby controlling the arc-shaped cover plate (29) to close the opening of the receiving roller (28) so that the material cannot fall out. S4. Then the receiving roller (28) drives the material to continue to rotate, and by starting the sixth motor (38), the sixth motor (38) can drive the connecting shaft (39) to rotate. Then the connecting shaft (39) drives each stirring blade (40) to rotate, so that while the material is rotating and churning, the stirring blade (40) can beat and collide with the material to further disperse the material. S5. When the receiving roller (28) drives the material to rotate above the receiving frame (14), the opening of the receiving roller (28) is facing down. By controlling the fifth motor (35) to drive the connecting handle (36) to rotate, the arc-shaped cover plate (29) can slide and open the opening, so that the material in the receiving roller (28) can fall out and land on the receiving frame (14). Through the cyclic rotation of multiple sets of receiving rollers (28), continuous and uniform intermittent receiving and unloading can be achieved. S6. Then the material can flow along the receiving frame (14) to the magnetic cylinder (4). During the flow, the third motor (22) can be started, so that the third motor (22) drives the two synchronous pulleys (20) to rotate through the synchronous belt (21). Then the two threaded rods (16) drive the movable block (17) to move in the mounting frame (15), so that the movable block (17) can drive the scraper (19) to move back and forth above the receiving frame (14). By the two sets of scrapers (19) being staggered, the material flowing on the receiving frame (14) can be scraped flat. S7. Afterwards, the material is evenly sprinkled on the magnetic cylinder (4), and the second pulley (8) is driven to rotate by the first motor (6). The second pulley (8) drives the first pulley (7) to rotate through the belt (9), which in turn drives the magnetic cylinder (4) to rotate. The magnetic cylinder (4) can adsorb the iron material in the material, while the material without iron material can continue to fall onto the feeding belt (2). As the magnetic cylinder (4) rotates, the iron material is scraped off the feeding frame (23) by the abutment plate (24). At the same time, the second motor (13) drives the rotating roller (11) to rotate, which drives the brush plate (12) to rotate. Then the brush plate (12) further sweeps down the iron material gathered between the abutment plate (24) and the magnetic cylinder (4).
