Description

Technical Field

[0001] This application relates to the technical field of electromagnetic material separation, and in particular to a magnetic separator. Background Technology

[0002] Magnetic separators are among the most widely used and versatile machines in industry, suitable for separating substances with differences in magnetic properties. Depending on the material being separated, magnetic separators are divided into dry magnetic separators and wet magnetic separators. Dry magnetic separators are typically used for separating dry magnetic minerals and are suitable for wet magnetic separation of materials such as magnetite, pyrrhotite, roasted ore, and ilmenite with a particle size of less than 3mm. They are also used for iron removal from materials such as coal, non-metallic minerals, and building materials.

[0003] The most common dry magnetic separator is the two-roll magnetic separator. In use, the material to be separated is fed onto the first separating roller, which separates the iron in the material from other materials. The iron-free material is then conveyed to the second separating roller, which separates the titanium ore from other materials, thus completing the separation.

[0004] In related technologies, titanium ore is separated by a first sorting roller and a second sorting roller. However, since titanium ore has weak magnetism, some titanium ore is easily discharged with non-magnetic ore during the sorting process, which may lead to tailings runoff and affect the titanium ore sorting effect. Summary of the Invention

[0005] In order to reduce the adverse effects on the titanium ore sorting effect, this application provides a magnetic separator.

[0006] The magnetic separator provided in this application adopts the following technical solution: A magnetic separator includes a frame and an iron removal roller rotatably connected to the upper side of the frame. A titanium selection roller parallel to the iron removal roller is rotatably connected to the lower side of the frame. The magnetic force of the titanium selection roller is greater than that of the iron removal roller. A guide plate inclined downward toward the titanium selection roller is provided on the lower side of the iron removal roller. A corresponding first motor is installed at one end of both the iron removal roller and the titanium selection roller. A pre-magnetizing component for pre-magnetizing the material is provided inside the frame.

[0007] By adopting the above technical solution, the first motor drives the iron removal roller and the titanium separation roller to rotate. After the iron ore is separated by the iron removal roller, the material moves to the pre-magnetizing component. After pre-magnetization, the magnetism of the weak magnetic ore is enhanced, which makes it easier to remove the non-magnetic ore in the material. At this time, the weak magnetic ore with enhanced magnetism moves to the titanium separation roller, thereby separating the intercalary ore and titanium ore in the weak magnetic ore, reducing the possibility that some titanium ore is easily discharged with non-magnetic ore, thus causing tailings runoff, and improving the titanium ore separation effect.

[0008] Optionally, the pre-magnetizing assembly includes a pre-magnetizing roller rotatably connected in the frame and located between the iron removal roller and the titanium selection roller. The pre-magnetizing roller also has a guide plate that is inclined downward toward the titanium selection roller on its lower side. The magnetic force of the pre-magnetizing roller is greater than that of the titanium selection roller. A first motor is also installed at one end of the pre-magnetizing roller.

[0009] By adopting the above technical solution, the first motor corresponding to the pre-magnetic roller drives the pre-magnetic roller to rotate. At this time, the material after iron removal moves and comes into contact with the pre-magnetic roller, which facilitates the pre-magnetic roller to fully magnetize the weakly magnetic minerals in the material and remove the non-magnetic minerals in the material. This increases the recovery rate of titanium ore, reduces the possibility that some titanium ore is easily discharged with non-magnetic minerals, and thus causes tailings runoff, thereby improving the titanium ore separation effect.

[0010] Optionally, a raw ore bin is installed on the upper side of the frame exterior, located above the iron removal roller and on the side of the frame away from the iron removal roller. The raw ore bin has an opening facing downward and is inserted into the frame. Inside the frame, a first feeding plate is provided, with its end fixedly connected to the inner wall of the frame near the raw ore bin and inclined downward toward the other side of the frame. Inside the frame, a second feeding plate is installed on the side near the iron removal roller, located below the first feeding plate and inclined downward toward the raw ore bin. A conveyor belt is installed on the first feeding plate to drive the material to move toward the second feeding plate. A spreading assembly for spreading the material is provided on the upper side of the first feeding plate and at the end near the raw ore bin.

[0011] By adopting the above technical solution, during the process of the material moving from the opening on the lower side of the raw ore bin to the first feeding plate, the spreading component on the upper side of the first feeding plate spreads the material evenly along the width direction of the first feeding plate and drives the spread material to fall onto the conveyor belt on the first feeding plate. At this time, the conveyor belt drives the spread material to move towards the second feeding plate and then moves it to the iron removal roller through the second feeding plate. This makes it easier for the material to fully contact the side wall of the iron removal roller, reducing the possibility of material accumulation and improving the titanium ore separation effect.

[0012] Optionally, the paving assembly includes a rotating disk installed on the lower side of the raw ore bin. The rotating disk has a discharge hole on its upper side that spirals along the center of the rotating disk toward the edge of the rotating disk and penetrates the rotating disk. A discharge cylinder is inserted into the middle of the upper side of the rotating disk, which is directly opposite the opening on the lower side of the raw ore bin. The discharge cylinder has a discharge port on its lower side that communicates with the end of the discharge hole. A sliding plate is inserted into and slidably connected to the discharge cylinder to block the discharge port. The first discharge plate is provided with a rotating component that drives the rotating disk to rotate. A discharge assembly for controlling the discharge from the discharge hole is provided on the lower side of the rotating disk.

[0013] By adopting the above technical solution, the material in the original ore bin enters the feeding cylinder and moves through the feeding port on one side of the feeding cylinder to the feeding hole on the rotary disk. At this time, the sliding plate opens and the feeding component blocks the feeding hole. The rotating component drives the rotary disk to rotate, and the material moves along the feeding hole until it is filled. At this time, the material is evenly spread along the width direction of the first feeding plate. The rotary disk stops rotating and drives the feeding component to open the feeding hole. At this time, the sliding plate blocks the feeding port, and the material filled in the feeding hole falls onto the conveyor belt, which facilitates full contact with the side wall of the iron removal roller, reduces the possibility of material accumulation, and improves the titanium ore separation effect.

[0014] Optionally, the lower side of the outer circumference of the rotating disk is provided with an insertion groove. The feeding assembly includes a drive ring that is sleeved and rotatably connected to the rotating disk through the insertion groove. The lower side of the drive ring is provided with a plurality of sealing plates evenly distributed along the circumference of the drive ring. The sealing plates can be spliced ​​together to form a circle and block the feeding hole. The side of the sealing plate away from the center of the drive ring is inserted and rotatably connected to a drive rod that is fixedly connected to the drive ring. The lower side of the drive ring is provided with a drive component that drives the sealing plate to rotate and open along the corresponding drive rod.

[0015] By adopting the above technical solution, during the process of material movement and filling the discharge hole, the sealing plates are spliced ​​together to seal the discharge hole. When the material fills the discharge hole, the driving component drives the driving ring to rotate and causes the sealing plate to rotate along the corresponding driving rod in a direction away from the center of the rotating disk until the discharge hole opens. At this time, the material passes through the discharge hole and falls onto the conveyor belt, which facilitates the uniform spreading of the material along the width direction of the first discharge plate and reduces the possibility of material accumulation.

[0016] Optionally, the driving component includes a fixed ring mounted on the upper side of the first unloading plate, a control ring located on the upper side of the fixed ring on the lower side of the sealing plate, an installation ring whose edge is inserted into the inner wall of the fixed ring and rotatably connected to the fixed ring on the lower side of the control ring, a first gear fixedly connected to the sealing plate on the lower side of each driving rod, a rack corresponding to the first gear installed on the inner wall of the control ring, a torsion spring installed between the sealing plate and the driving ring, a rotating component for driving the driving ring to rotate and a fixing component for fixing the control ring on the fixed ring, and a connecting component for controlling the rotation of both the control ring and the driving ring.

[0017] By adopting the above technical solution, when the rotating component drives the rotating disk to rotate, the connecting component keeps the control ring and the drive ring relatively fixed, and the sealing plate blocks the discharge hole. The torsion spring does not deform. During discharge, the fixing component fixes the mounting ring and the fixing ring. At this time, the control ring is difficult to rotate. The connecting component releases the fixing between the control ring and the drive ring, and the rotating component drives the drive ring to rotate. At this time, the rack on the control ring drives the corresponding first gear to drive the sealing plate to rotate along the corresponding drive rod in a direction away from the center of the rotating disk, which facilitates opening the discharge hole and improves the discharge efficiency.

[0018] Optionally, the rotating component includes a first gear ring sleeved on the outside of the drive ring and fixedly connected to the drive ring, a second gear meshing with the first gear ring on the fixed ring, and a second motor mounted on the upper side of the second gear.

[0019] By adopting the above technical solution, the second motor drives the second gear to rotate and drives the drive ring to rotate through the first gear ring. At this time, the fixing component fixes the mounting ring and the fixing ring, and the connecting component releases the connection between the control ring and the drive ring. This allows the first gear to rotate around the drive rod and move around the drive ring under the drive of the corresponding rack, which facilitates the rotation of the sealing plate and the opening of the feeding port, thus facilitating the uniform spreading of materials and improving the feeding efficiency.

[0020] Optionally, the rotating component includes a second gear ring that is sleeved and fixedly connected to the control ring. A first hydraulic cylinder is mounted on the lower side of the second gear, and the telescopic rod of the first hydraulic cylinder moves upward and drives the second gear to move.

[0021] By adopting the above technical solution, the telescopic rod of the first hydraulic cylinder drives the second gear to move in the height direction of the first material feeding plate, thereby controlling the second gear to mesh with the first gear ring or the second gear ring, which facilitates the rotation of the rotating disk or the drive ring, and thus facilitates uniform spreading or feeding, improving work efficiency.

[0022] Optionally, the mounting ring has multiple fixing grooves on the outer circumferential surface of the side into which it is inserted. The fixing member includes a fixing rod that is inserted into and slidably connected to the side of the fixing ring near the first hydraulic cylinder and faces the fixing ring. A spring is installed between the fixing rod and the fixing ring. An abutment rod is fixedly connected to the first hydraulic cylinder. The end of the abutment rod near the fixing rod is set as an inclined surface that is upward and away from the fixing rod.

[0023] By adopting the above technical solution, when the telescopic rod of the first hydraulic cylinder drives the second gear to move upward and mesh with the first gear ring, the abutting rod moves upward with the first hydraulic cylinder and drives the fixed rod to move towards the fixed groove through its own inclined surface until it is inserted into one of the fixed grooves. At this time, the spring is compressed, and the fixed ring, mounting ring and control ring are relatively fixed, which facilitates driving the drive ring to rotate and controlling the opening or closing of the sealing plate, thereby improving the material feeding efficiency.

[0024] Optionally, the connector includes a connecting rod with one end passing through the rotary disk, the drive ring, and the sealing plate near the first hydraulic cylinder and inserted into the control ring and slidably connected to the control ring, and the other end of the connecting rod being sleeved and fixedly connected to the telescopic rod of the first hydraulic cylinder.

[0025] By adopting the above technical solution, when the rotating disk is driven to rotate, the connecting rod passes through the rotating disk, the driving ring, and one of the sealing plates and is inserted into the control ring. At this time, the mounting ring and the fixed ring rotate relative to each other, which facilitates driving the rotating disk to rotate through the control ring. When the sealing plate is driven to open, the connecting rod moves upward with the telescopic rod of the first hydraulic cylinder and disengages from one of the sealing plates and the control ring. At this time, the fixed rod fixes the mounting ring, which facilitates driving the driving ring to rotate and opening the sealing plate, thereby facilitating material unloading and improving work efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The first motor corresponding to the premagnetizing roller drives the premagnetizing roller to rotate. At this time, the material after iron removal moves and comes into contact with the premagnetizing roller, which facilitates the premagnetizing roller to fully magnetize the weak magnetic minerals in the material and remove the non-magnetic minerals in the material, thereby increasing the recovery rate of titanium ore and reducing the possibility that some titanium ore is easily discharged with non-magnetic minerals, thus causing tailings runoff. 2. The material from the raw ore bin enters the feeding cylinder and moves through the feeding port on one side of the feeding cylinder to the feeding hole on the rotating disk. At this time, the sliding plate opens and the feeding component blocks the feeding hole. The rotating component drives the rotating disk to rotate. At this time, the material moves along the feeding hole until it is filled. At this time, the material is evenly spread along the width of the first feeding plate. The rotating disk stops rotating and drives the feeding component to open the feeding hole. At this time, the sliding plate blocks the feeding port. The material filled in the feeding hole falls onto the conveyor belt, which facilitates full contact with the side wall of the iron removal roller and reduces the possibility of material accumulation. 3. The second motor drives the second gear to rotate and drives the drive ring to rotate through the first gear ring. At this time, the fixing component fixes the mounting ring and the fixing ring, and the connecting component releases the connection between the control ring and the drive ring. This allows the first gear to rotate around the drive rod and move around the drive ring under the drive of the corresponding rack, which facilitates the rotation of the sealing plate and the opening of the feeding port, which facilitates the uniform spreading of materials and improves the feeding efficiency.

Detailed Implementation

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] This application discloses a magnetic separator. (Refer to...) Figure 1 and Figure 2 A magnetic separator includes a vertical frame 1 and a raw ore bin 11 installed on the upper side of the frame 1. The raw ore bin 11 has an opening at its lower end and is inserted into the frame 1. An iron removal roller 12 is rotatably connected to the upper side of the frame 1, located below the raw ore bin 11 and arranged along the width direction of the frame 1. The iron removal roller 12 is horizontal and located at one end of the frame 1 in the horizontal direction. An iron ore bin 121 is fixedly connected inside the frame 1, located below the iron removal roller 12 and receiving iron ore. A guide plate 13 is provided on one side of the iron removal roller 12 near the other end of the frame 1 in the horizontal direction, located below the iron removal roller 12 and fixedly connected to the frame 1 on one side. The guide plate 13 is downward and inclined away from the iron removal roller 12.

[0037] Inside the frame 1, a titanium-selecting roller 14 is rotatably connected to the lower side, parallel to the iron-removing roller 12 and located at the end of the frame 1 away from the iron-removing roller 12 in the horizontal direction. The magnetic force of the titanium-selecting roller 14 is greater than that of the iron-removing roller 12. A concentrate bin 141, which is fixedly connected to the frame 1 and receives titanium ore, is provided on the lower side of the titanium-selecting roller 14 away from the iron-removing roller 12. A secondary ore bin 142, which is fixedly connected to the frame 1 and receives secondary ore, is also provided on the lower side of the titanium-selecting roller 14 near the secondary ore bin 142. A guide plate 13, which is fixedly connected to the frame 1 and inclined downward towards the secondary ore bin 142, is also provided on the lower side of the titanium-selecting roller 14. A first motor (not shown in the figure) is installed on the frame 1, corresponding to the titanium-selecting roller 14 and the iron-removing roller 12 respectively. The frame 1 has a vertical baffle 15 fixedly connected inside, located on the side of the iron removal roller 12 near the titanium selection roller 14, and the frame 1 has a pre-magnetizing component 2 located between the iron removal roller 12 and the titanium selection roller 14.

[0038] The pre-magnetizing assembly 2 includes a pre-magnetizing roller 21 rotatably connected to the frame 1 and parallel to the iron removal roller 12. The magnetic force of the pre-magnetizing roller 21 is greater than that of the titanium separation roller 14. A first motor (not shown in the figure) is also fixedly connected to the frame 1 at one end of the pre-magnetizing roller 21. A guide plate 13 is also provided on the side of the pre-magnetizing roller 21 near the titanium separation roller 14, which is located below the pre-magnetizing roller 21 and inclined downward toward the titanium separation roller 14. A tailings bin 22 is installed on the frame 1, located below the pre-magnetizing roller 21 and on the side of the guide plate 13 corresponding to the pre-magnetizing roller 21 near the titanium separation roller 14. A vertical baffle 15 is also fixedly connected to the frame 1 on the side of the pre-magnetizing roller 21 near the titanium separation roller 14.

[0039] The first motor drives the iron removal roller 12, the pre-magnetizing roller 21, and the titanium separation roller 14 to rotate. After the iron removal roller 12 separates the iron ore into the iron ore bin 121, the material moves to the pre-magnetizing roller 21 through the guide plate 13 and comes into contact with the pre-magnetizing roller 21. This facilitates the pre-magnetizing roller 21 to fully magnetize the weakly magnetic minerals in the material, while removing the non-magnetic minerals and conveying them to the tailings bin 22. The weakly magnetic minerals, after being magnetically enhanced, move to the titanium separation roller 14 through the corresponding guide plate 13, thereby separating the intercalated minerals and titanium ore in the weakly magnetic minerals. At this time, the intercalated minerals move to the second ore bin 142, and the titanium ore moves to the concentrate bin 141, increasing the recovery rate of titanium ore, reducing the possibility of some titanium ore being discharged with non-magnetic minerals, and thus causing tailings runoff, thereby improving the titanium ore separation effect.

[0040] Reference Figure 1 and Figure 2 The raw ore bin 11 is located at the end of the frame 1 away from the iron removal roller 12 in the horizontal direction. The upper end of the frame 1 is fixedly connected to a first feeding plate 3 located above the iron removal roller 12 and inclined downward toward the iron removal roller 12. A conveyor belt 31 for conveying materials along the length of the first feeding plate 3 is installed on the first feeding plate 3. A second feeding plate 32 is located on the side of the first feeding plate 3 near the iron removal roller 12 and fixedly connected to the inner wall of the frame 1. The second feeding plate 32 is inclined downward toward the side near the first feeding plate 3. A spreading component 4 for evenly spreading materials is provided on the first feeding plate 3.

[0041] Reference Figure 2 , Figure 3 and Figure 4 The paving assembly 4 includes a horizontal rotating disk 41 located above the first feeding plate 3. The diameter of the rotating disk 41 is adapted to the width of the first feeding plate 3, and a retaining edge 411 with an outer diameter equal to the diameter of the rotating disk 41 and integrally formed with the rotating disk 41 is fixedly connected to the upper edge of the rotating disk 41. A feeding hole 412 is provided on the rotating disk 41, spirally arranged from its own center towards the retaining edge 411, and the feeding hole 412 penetrates the rotating disk 41 vertically. A vertical feeding cylinder 42 is inserted into and fixedly connected to the center of the upper side of the rotating disk 41, penetrating the rotating disk 41. The upper end of the feeding cylinder 42 is directly opposite the raw ore bin 11, and a feeding port 421 communicating with the feeding hole 412 is provided on one side of the feeding cylinder 42.

[0042] Reference Figure 2 , Figure 3 and Figure 4A sliding plate 422, which blocks the discharge port 421, is inserted into and slidably connected to the side of the discharge cylinder 42 near the discharge port 421. A vertical sliding rod 423, with its upper end penetrating the discharge cylinder 42, is fixedly connected to the upper side of the sliding plate 422. The upper side of the sliding rod 423 is bent to a vertical position, and a vertical second hydraulic cylinder 424, which is fixedly connected to the sliding rod 423, is installed on the outer wall of the discharge cylinder 42. The first discharge plate 3 is provided with a rotating component 43 that drives the rotating disk 41 to rotate around its own center, and a discharge assembly 5 that controls the blocking or opening of the discharge hole 412 is provided on the lower side of the rotating disk 41.

[0043] As the material moves from the opening on the lower side of the raw ore bin 11 to the first feeding plate 3, the material in the raw ore bin 11 enters the feeding cylinder 42 and moves through the feeding port 421 on one side of the feeding cylinder 42 to the feeding hole 412 on the rotating disk 41. At this time, the sliding plate 422 opens, and the feeding assembly 5 blocks the feeding hole 412. The rotating component 43 drives the rotating disk 41 to rotate. At this time, the material moves along the feeding hole 412 until it fills the feeding hole 412. The material is evenly spread along the width direction of the first feeding plate 3, and the rotation stops. The rotating disk 41 drives the feeding assembly 5 to open the feeding hole 412. At this time, the second hydraulic cylinder 424 drives the sliding rod 423 to drive the sliding plate 422 to block the feeding port 421. The material filled in the feeding hole 412 falls onto the conveyor belt 31. The conveyor belt 31 drives the spread material to move towards the second feeding plate 32 and moves it to the iron removal roller 12 through the second feeding plate 32. This makes it easier for the material to fully contact the side wall of the iron removal roller 12, reducing the possibility of material accumulation and improving the titanium ore separation effect.

[0044] Reference Figure 2 , Figure 3 and Figure 5 An annular insertion groove 413 is provided on the lower side of the outer circumference of the rotating disk 41. The feeding assembly 5 includes a drive ring 51 that is sleeved on the outer wall of the rotating disk 41 through the insertion groove 413 and rotatably connected to the rotating disk 41. A plurality of vertical drive rods 52 are fixedly connected to the lower side of the drive ring 51 and are evenly distributed along the circumference of the drive ring 51. (Refer to...) Figure 5 and Figure 6 Each drive rod 52 is fitted with a horizontal sealing plate 53 that contacts the lower side of the rotating disk 41. A torsion spring is installed between the sealing plate 53 and the drive ring 51. The sealing plates 53 can be spliced ​​together to block the feed hole 412. At this time, the torsion spring is not deformed. The drive ring 51 is provided with a drive component 54 on the lower side to drive the sealing plate 53 to rotate along the corresponding drive rod 52 in a direction away from the center line of the rotating disk 41.

[0045] Reference Figure 3 , Figure 5 and Figure 6The driving component 54 includes a horizontal fixed ring 541 located below the driving ring 51. Mounting rods 542 are fixedly connected to both sides of the fixed ring 541. The ends of the mounting rods 542 that are far apart from each other are bent downwards and fixedly connected to the first feed plate 3. A horizontal control ring 543 is provided below the driving ring 51. A mounting ring 544 with an outer diameter equal to the inner diameter of the fixed ring 541 and inserted into the fixed ring 541 is fixedly connected to the lower side of the control ring 543. A connecting ring 545 integrally formed with the mounting ring 544 is sleeved and fixedly connected to the lower side of the mounting ring 544. The connecting ring 545 is inserted into the fixed ring 541 and rotatably connected to the fixed ring 541.

[0046] Reference Figure 5 , Figure 6 and Figure 7 The lower ends of the drive rods 52 are all located in the control rings 543, and each drive rod 52 is sleeved and rotatably connected to a first gear 546 located on the lower side of the sealing plate 53 and fixedly connected to the corresponding sealing plate 53. Each drive ring 51 has a rack 547 fixedly connected to its inner wall, integrally formed with the drive ring 51 and corresponding to and meshing with the first gear 546. The teeth of the first gear 546 are all located on the side closest to the corresponding first rack 547. The mounting rod 542 on one side of the fixed ring 541 is provided with a rotating component 55 for driving the drive ring 51 to rotate and a fixing component 56 for controlling the rotation of the fixed ring 541 and the connecting ring 545. The fixed ring 541 is also provided with a connecting component 57 for controlling the relative rotation of the drive ring 51 and the control ring 543.

[0047] When the rotating component 43 drives the rotating disk 41 to rotate, the material moves and fills the discharge hole 412. The sealing plates 53 splice together and seal the discharge hole 412. The connecting component 57 makes the control ring 543 and the drive ring 51 relatively fixed. The sealing plate 53 seals the discharge hole 412, and the torsion spring does not deform. When the material fills the discharge hole 412, the fixing component 56 fixes the mounting ring 544 and the fixing ring 541. At this time, the control ring 543 is difficult to rotate. The connecting component 57 releases the fixing of the control ring 543 and the drive ring 51. The rotating component 55 drives the drive ring 51 to rotate. At this time, the rack 547 on the control ring 543 drives the corresponding first gear 546 to drive the sealing plates 53 to rotate along the corresponding drive rod 52 in a direction away from the center of the rotating disk 41 until the discharge hole 412 opens. At this time, the material passes through the discharge hole 412 and falls onto the conveyor belt 31, which facilitates the even spreading of the material along the width direction of the first discharge plate 3 and reduces the possibility of material accumulation.

[0048] Reference Figure 5 and Figure 6The rotating component 55 includes a first gear ring 551 sleeved on the outer wall of the drive ring 51 and fixedly connected to the drive ring 51. A horizontal second gear 552 is meshed on the side of the first gear ring 551 near one of the mounting rods 542. A horizontal mounting plate 554 is provided on the lower side of the second gear 552. The second gear 552 is rotatably connected to the mounting plate 554. A second motor 553 located on the upper side of the second gear 552 and whose output shaft is fixedly connected to the second gear 552 is mounted on the mounting plate 554.

[0049] Reference Figure 5 and Figure 6 The rotating component 43 includes a second gear ring 431 that is sleeved on the outer side of the upper side of the control ring 543 and fixedly connected to the control ring 543. The second gear 552 can also mesh with the second gear ring 431. A first hydraulic cylinder 432 with a vertical extension rod pointing upward and fixedly connected to the lower side of the mounting plate 554 is fixedly connected to the upper side of the mounting rod 542 near the second gear 552.

[0050] Reference Figure 5 , Figure 6 and Figure 7 The connecting ring 545 has multiple evenly distributed fixing slots 5451 on its outer circumferential surface, with the slots facing away from its center. The fixing member 56 includes a fixing rod 561 located on the side of the fixing ring 541 near the first hydraulic cylinder 432, with one end inserted into the fixing ring 541 and slidably connected to it. The end of the fixing rod 561 can be inserted into one of the fixing slots 5451 on the connecting ring 545. A spring 562 is installed between the end of the fixing rod 561 located on the outer side of the fixing ring 541 and the outer wall of the fixing ring 541. When the spring 562 is at its original length, the end of the fixing rod 561 is not inserted into the fixing slot 5451 on the connecting ring 545.

[0051] A vertical abutment rod 563 is provided on the side of the fixed rod 561 near the first hydraulic cylinder 432. The upper end of the abutment rod 563 is bent towards the first hydraulic cylinder 432 and fixedly connected to the telescopic rod of the first hydraulic cylinder 432. The lower end of the abutment rod 563 is bent towards the fixed rod 561. The end of the abutment rod 563 near the fixed rod 561 is set as an inclined surface that slopes upward and away from the fixed rod 561. When the spring 562 is at its original length, the end of the abutment rod 563 near the fixed rod 561 is located below the fixed rod 561, and the inclined surface on the abutment rod 563 contacts the end of the fixed rod 561.

[0052] Reference Figure 5 and Figure 6The connecting member 57 includes a connecting rod 571 located on the side of the flange 411 near the first hydraulic cylinder 432, passing through the flange 411, the rotating disk 41, the drive ring 51, the sealing plate 53 near the first hydraulic cylinder, and inserted into the control ring 543. The connecting rod 571 is slidably connected to the flange 411, the rotating disk 41, the drive ring 51, the sealing plate 53 near the first hydraulic cylinder, and the control ring 543, and the upper end of the connecting rod 571 is bent towards the first hydraulic cylinder 432. A vertical stabilizing rod 572 located on the side of the first hydraulic cylinder 432 away from the flange 411 is fixedly connected to the bent end of the connecting rod 571. The stabilizing rod 572 is integrally formed with the connecting rod 571, and the lower end of the stabilizing rod 572 is bent towards the first hydraulic cylinder 432 and fixedly connected to the telescopic rod of the first hydraulic cylinder 432.

[0053] When the drive disc 41 rotates, the second gear 552 meshes with the second gear ring 431, and the second motor 553 drives the second gear 552 to rotate the second gear ring 431. The connecting rod 571 passes through the disc 41, the drive ring 51, and one of the sealing plates 53 and is inserted into the control ring 543. The end of the abutment rod 563 near the fixed rod 561 is located below the fixed rod 561. At this time, the mounting ring 544 rotates relative to the fixed ring 541, which facilitates driving the disc 41 to rotate through the control ring 543.

[0054] When the sealing plate 53 is opened, the telescopic rod of the first hydraulic cylinder 432 drives the mounting plate 554, the second gear 552, and the second motor 553 to move upwards until they mesh with the first gear ring 551. The stabilizing rod 572 and the connecting rod 571 move upwards with the telescopic rod of the first hydraulic cylinder 432 and disengage from one of the sealing plates 53 and the control ring 543. The abutting rod 563 moves upwards with the telescopic rod of the first hydraulic cylinder 432 and pushes the fixing rod 561 into the fixing groove 5451 through its own inclined surface. Thus, the control ring 543 and the fixing ring 541 are fixed by the connecting ring 545 and the mounting ring 544, which makes it easier for the second motor 553 to drive the second gear 552 to rotate and drive the driving ring 51 to rotate through the first gear ring 551 to open the sealing plate 53, thereby facilitating material unloading.

[0055] The implementation principle of a magnetic separator according to an embodiment of this application is as follows: After the iron ore is separated into the iron ore bin 121 by the iron removal roller 12, the material is moved to the pre-magnetizing roller 21 by the guide plate 13. The pre-magnetizing roller 21 can fully magnetize the weak magnetic minerals in the material, while removing the non-magnetic minerals in the material and conveying them to the tailings bin 22. The weak magnetic minerals after magnetic enhancement are moved to the titanium separation roller 14 by the corresponding guide plate 13, thereby separating the intercalated minerals and titanium ore in the weak magnetic minerals, increasing the recovery rate of titanium ore, reducing the possibility of some titanium ore being discharged with non-magnetic minerals, and thus causing tailings runoff, thereby improving the titanium ore separation effect.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
