Description

Technical Field

[0001] This invention relates to the field of magnetic separation technology for ores, and in particular to a high-gradient wet magnetic separator for titanium ore. Background Technology

[0002] Magnetic separation is a type of fine separation for ilmenite. It utilizes the differences in magnetic permeability among various minerals. By passing them through a magnetic field, different minerals react differently to the magnetic field. Minerals with high magnetic permeability are attracted by the magnetic disk, and when they lose magnetism, they fall down and are collected through a collection funnel. Minerals with low magnetic permeability are not attracted and remain in the material or are carried away as tailings by the rotating conveyor belt, thus achieving separation.

[0003] In existing ore magnetic separation processes, such as Chinese patent with publication number CN117019389A, an iron ore magnetic separation device is disclosed, which includes a base, a fixing plate and a mounting shell, etc. The fixing plate is symmetrically fixed to the top of the base, and the mounting shell is fixed between the front sides of the fixing plates on the left and right sides.

[0004] In the aforementioned prior art, the iron ore is mainly crushed and refined, and then a magnetic roller is used to attract the iron ore and separate it from the stones. However, the prior art does not take into account that the finely crushed ore falls and impacts the cylindrical magnetic roller under the action of gravity. The falling stones may knock off the iron ore previously attracted by the magnetic roller. The prior art also does not control the falling of the ore, and cannot ensure that the ore falls evenly in the magnetic field of the magnetic roller. This may lead to excessive local attraction of the magnetic roller until it can no longer attract ore. In fact, when the amount of ore falling is too large, the magnetic roller may become saturated and unable to attract the iron ore falling later.

[0005] Therefore, there is still room for improvement in the aforementioned existing technologies. Summary of the Invention

[0006] To ensure the uniform application of magnetic force to titanium ore during the magnetic separation process and guarantee the accuracy of the separation, this application provides a high-gradient wet magnetic separator for titanium ore, employing the following technical solution: A high-gradient titanium ore wet magnetic separator includes a frame, a feeding module, a sorting module, a magnetic separation module, and a combing module. The feeding module is located at the top of the frame, and the sorting module is located inside the feeding module. After the ore enters the feeding module, it is screened and sorted by size and conveyed accordingly. The magnetic separation module is located at the bottom of the frame. The magnetic separation module carries the incoming ore and conveys the magnetic titanium ore and non-magnetic stones to designated positions according to their magnetic differences. The combing module is located inside the frame, between the feeding module and the magnetic separation module. The combing module turns, spreads, combs, and performs magnetic separation on the ore of specified sizes, thereby performing secondary screening of the ore.

[0007] Preferably, the feeding module includes a vertical pipe, an inclined flow channel, a release port, a flow limiting mechanism, and a discharge mechanism. The vertical pipe is installed at the top middle position of the frame. Ore is fed into the present application from the upper end of the vertical pipe. An inclined flow channel is connected and installed in the middle of the right side wall of the vertical pipe. The release port is installed at the lower end of the vertical pipe. The flow limiting mechanism and the discharge mechanism are arranged sequentially from top to bottom in the release port. In the initial state, the discharge mechanism closes the lower end of the release port. After the ore falls from the vertical pipe into the release port, the discharge mechanism opens periodically to discharge the ore from the release port. The flow limiting mechanism ensures that the amount of ore released from the release port each time is constant.

[0008] Preferably, the flow limiting mechanism includes a flow limiting plate, a first rack plate, a flow limiting gear, and a second rack plate. The flow limiting plate is slidably disposed in the middle of the release port. Before the discharge mechanism is opened, the flow limiting plate is inserted into the release port to divide the release port into upper and lower parts. After the discharge mechanism is opened, only the ore in the lower part is released from the release port, thereby achieving the purpose of quantitative release. The first rack plate is symmetrically installed on the front and rear sides of the flow limiting plate. The flow limiting gear is symmetrically rotated on the side wall of the frame. The upper part of the flow limiting gear meshes with the first rack plate. The second rack plate is symmetrically slidably disposed in the frame. The left end of the second rack plate is fixedly connected to the combing module. The lower part of the second rack plate meshes with the lower part of the flow limiting gear. The second rack plate moves in the left and right direction with the combing module. When the second rack plate meshes with the flow limiting gear, the flow limiting gear rotates, and the first rack plate meshing with the flow limiting gear moves in the left and right direction, thereby allowing the flow limiting plate to close or not close the release port.

[0009] Preferably, the discharge mechanism includes a discharge valve, a push-pull plate, and a squeeze plate. The discharge valve is slidably disposed at the bottom of the release port. A return spring is connected between the discharge valve and the release port, and the return spring serves to reset the valve. An L-shaped push-pull plate is installed at the right end of the discharge valve. The squeeze plate is slidably disposed in the frame through the combing module. The squeeze plate and the push-pull plate are in contact and squeezed together. The squeeze plate moves with the combing module in the left and right direction. When the squeeze plate moves to the right and contacts and squeezes the push-pull plate, the discharge valve is gradually pulled to the right, causing the release port to open. When the squeeze plate moves to the left and no longer squeezes the push-pull plate, the discharge valve resets under the action of the return spring.

[0010] Preferably, the sorting module includes sorting rods and buffer blocks. The sorting rods are evenly installed in the middle of the vertical pipe along the front-to-back direction, and the sorting rods are arranged in a gradually downward sloping structure from left to right. The positions of the sorting rods correspond to the inclined flow channels. When the ore is fed into this application, small ore falls through the gaps between the sorting rods into the release port, while large ore is intercepted between the sorting rods and slides into the inclined flow channels along the inclination angle of the sorting rods. Water channels are opened inside the sorting rods, and the buffer blocks are slidably disposed at the upper end of the sorting rods. The buffer blocks and the sorting rods are aligned... A buffer spring is connected between the two parts, which plays a flexible buffering role. The top of the buffer block has a rounded pointed structure. When the falling ore hits the top of the buffer block, it will be separated to both sides and will not be trapped. The buffer block is made of polyurethane, so it will not have a rigid collision with the ore, reducing the occurrence of ore breakage and splashing. A falling slide groove is opened on the side wall of the buffer block along its length. Water spray holes are evenly inclined in the falling slide groove. The water spray holes are connected to the water channel. Water is sprayed out at an angle from the water spray holes to help the ore on the sorting rod slide into the inclined channel.

[0011] Preferably, the magnetic separation module includes a conveyor group, a secondary conveyor group, and a high-pressure nozzle. The conveyor group is set in the frame, with the upper surface of the magnetic conveyor group arranged with the left side higher than the right side. Small ore from the release port falls onto the conveyor group, and the magnetic conveyor group attracts and carries the equally magnetic titanium ore upwards, while non-magnetic stones slide downwards along the upper surface of the conveyor group under the action of gravity, thereby achieving the purpose of separating titanium ore from ordinary stones. The secondary conveyor group is set at the right end of the upper surface of the conveyor group, and there is a certain distance between the magnetic secondary conveyor group and the conveyor group. The right end of the inclined channel corresponds to the position of the secondary conveyor group. The inclined channel transports large ore to the secondary conveyor group, and the secondary conveyor group screens the titanium ore in the large ore. The screening of small ore and large ore is carried out separately to avoid mutual interference. The high-pressure nozzle is set in the left side wall of the frame, and the position of the high-pressure nozzle corresponds to the conveyor group. High-pressure water jets sprayed from the high-pressure nozzle wash away the titanium ore adsorbed on the conveyor group.

[0012] Preferably, the combing module includes a guide rail, a combing component, a crossbar, a locking mechanism, a reset block, and an air blowing mechanism. The guide rail is installed in the frame, and the angle of the guide rail is consistent with the angle of the conveying group. The combing component is slidably mounted on the guide rail via a drive slider. The combing component flips and combs the small ores on the conveying group, making them evenly spread on the surface of the conveying group, thereby making the titanium ore more fully contacted with the conveying group and being attracted by magnetism, thus improving the screening rate of titanium ore. The crossbar is installed at the left end of the guide rail. The locking mechanism is located inside the combing component. When the combing component moves to the leftmost position, it is squeezed by the crossbar to adjust its angle. The locking mechanism temporarily locks the angle of the combing component. The reset block is installed at the right end of the guide rail. The inner side of the reset block has an angled structure. The reset block unlocks the angle of the combing component. The air blowing mechanism is located inside the combing component.

[0013] Preferably, the combing assembly includes an angle plate, a sliding block, and a combing plate. The angle plate is rotatably mounted in the sliding block via a pin. A torque spring connects the angle plate and the sliding block, keeping the angle plate at a certain angle to the guide rail. The sliding block is slidably mounted on the guide rail via a drive slider. The lower end of the angle plate has evenly spaced inclined open slots. The lower surface of the angle plate has evenly spaced air blowing holes, which are connected to the air blowing mechanism. The combing plate is rotatably mounted in the open slots. A compression spring connects the combing plate and the open slots, serving a reset function. The surface of the combing plate has a second air blowing hole, which is connected to the air blowing mechanism.

[0014] Preferably, the locking mechanism includes a snap-fit ​​component, an auxiliary rod, a compression spring, and a locking component. The snap-fit ​​component is symmetrically slidably disposed in the angle plate. An auxiliary rod is installed at the rear end of the U-shaped snap-fit ​​component. The compression spring located between the auxiliary rods is disposed in the angle plate. The compression spring always maintains an outward pushing tendency on the auxiliary rod. A locking groove is opened at the lower end of the auxiliary rod. The right end of the locking component is fixedly connected to the combing plate. The position of the locking component corresponds to the locking groove. The locking component is inserted into the locking groove to temporarily lock the position of the auxiliary rod.

[0015] Preferably, the air blowing mechanism includes an air pump, a valve body, a partition plate, and a push rod. The air pump is mounted on the upper surface of the angle plate, and the valve body is also mounted on the upper surface of the angle plate. The valve body has a hollow structure, and its side wall has, from top to bottom, an air outlet, an air inlet, and an air outlet 2. The air inlet is connected to the air pump, the air outlet 1 is connected to the air blowing hole 1, and the air outlet 2 is connected to the air blowing hole 2. The partition plate is slidably disposed inside the valve body, and a return spring is connected between the partition plate and the valve body. The return spring acts as a return mechanism. The partition plate has a push rod installed at the bottom, and the push rod is positioned corresponding to the combing plate. In the initial state, the partition plate is located at the bottom of the valve body (at this time, the partition plate is lower than the air inlet). At this time, the second air outlet is blocked, and the air inlet and the first air outlet are connected. The first air outlet performs air blowing. When the push rod is squeezed, the partition plate is pushed to the top of the valve body (at this time, the partition plate is higher than the air inlet). At this time, the first air outlet is blocked, and the air inlet and the second air outlet are connected. The second air outlet performs air blowing.

[0016] In summary, the beneficial technical effects of this application are as follows: This invention discloses a high-gradient wet magnetic separator for titanium ore. The ore is screened according to size, with large ore pieces conveyed to a secondary conveyor. Non-magnetic ore falls under gravity, while magnetic titanium ore rises under magnetic field adsorption. For smaller ore pieces, a design concept combining quantitative conveying, mechanical turning, and air blowing is employed. Quantitative conveying ensures that small ore pieces fall onto the conveyor for screening in a single, periodic, quantitative manner, preventing oversaturation of the machine. Mechanical turning and air blowing further agitate and spread the small ore pieces from multiple angles and directions, resulting in a more uniform and comprehensive exposure to the magnetic field, thus ensuring the accuracy of magnetic separation for small ore pieces.

[0019] The following is in conjunction with the appendix Figures 1-12 This application will be described in further detail.

[0020] This application discloses a high-gradient wet magnetic separator for titanium ore. By screening the ore according to its specifications, it performs separate magnetic separation on ores of different specifications, and focuses on quantitative screening of small ores. During the magnetic separation process, the small ores are agitated by air blowing and physically turned to make the arrangement of small ores uniform and ensure the accuracy of magnetic separation of small ores.

[0021] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, a high-gradient titanium ore wet magnetic separator includes a frame 1, a feeding module 2, a sorting module 3, a magnetic separation module 4, and a combing module 5. The feeding module 2 is located at the top of the frame 1, and the sorting module 3 is installed inside the feeding module 2. After the ore enters the feeding module 2, it is screened and sorted by size by the sorting module 3. The magnetic separation module 4 is located at the bottom of the frame 1. The magnetic separation module 4 carries the incoming ore and, based on the difference in magnetic properties, transports the magnetic titanium ore and the non-magnetic stones to designated positions respectively. The combing module 5 is located inside the frame, between the feeding module 2 and the magnetic separation module 4. The combing module 5 performs agitation, spreading, combing, and magnetic separation on the ore of specified sizes, thereby performing secondary screening of the ore.

[0022] In the actual screening process, the ore to be screened is put into the feeding module 2. The classification module 3 transports the ore to different positions in the magnetic separation module 4 according to its size. Large and small ores are magnetically separated at different positions in the magnetic separation module 4. Magnetic titanium ore rises continuously from right to left in the magnetic separation module 4, while non-magnetic stones fall continuously from left to right. The sorting module 5 continuously blows air to agitate and physically turn the small ores in the magnetic separation, so that the small ores are evenly spread in the magnetic separation module 4, thereby making the magnetic separation of small ores more accurate. This application divides the ore into different sizes and performs separate magnetic separation for ores of different sizes. Small ores that are more difficult to magnetically separate are turned and spread out in a targeted manner, so that the small ores are evenly exposed to the magnetic field, ensuring the accuracy of magnetic separation.

[0023] Reference Figure 4 , Figure 5 As shown, this application includes a feeding module 2 that controls the entry of ore. The feeding module 2 includes a vertical pipe 21, an inclined flow channel 22, a release port 23, a flow limiting mechanism 24, and a discharge mechanism 25. The vertical pipe 21 is installed at the top middle position of the frame 1. The ore is fed into this application from the upper end of the vertical pipe 21. The inclined flow channel 22 is connected to the middle of the right side wall of the vertical pipe 21. The release port 23 is installed at the lower end of the vertical pipe 21. The flow limiting mechanism 24 and the discharge mechanism 25 are arranged sequentially from top to bottom in the release port 23. In the initial state, the discharge mechanism 25 closes the lower end of the release port 23. After the ore falls from the vertical pipe 21 into the release port 23, the discharge mechanism 25 periodically opens to discharge the ore from the release port 23. The flow limiting mechanism 24 ensures that the amount of ore released from the release port 23 each time is constant.

[0024] In the actual feeding process, the ore is fed into this application from the vertical pipe 21. Large ore is intercepted by the classification module 3 and enters the inclined channel 22, while small ore falls directly into the release port 23. As the sorting module 5 moves, the discharge mechanism 25 periodically controls the release port 23 to open and release ore downwards. The flow limiting mechanism 24 controls the amount of ore released each time to a fixed value.

[0025] Reference Figure 6 As shown, the sorting module 5 performs single-quantity turning of small ore. To ensure that the amount of ore released from the release port 23 each time is a fixed value, this application provides a flow-limiting mechanism 24 and a discharge mechanism 25. The flow-limiting mechanism 24 includes a flow-limiting plate 241, a rack plate 242, a flow-limiting gear 243, and a rack plate 244. The flow-limiting plate 241 is slidably disposed in the middle of the release port 23. Before the discharge mechanism 25 is opened, the flow-limiting plate 241 is inserted into the release port 23, dividing the release port 23 into upper and lower regions. After the discharge mechanism 25 is opened, only the ore in the lower region is released from the release port 23, thereby achieving the purpose of quantitative release. The rack plates 241 are symmetrically installed on the front and rear sides of the flow-limiting plate 241. 242. The flow-limiting gear 243 is symmetrically rotated on the side wall of the frame 1. The upper part of the flow-limiting gear 243 meshes with the first rack plate 242. The second rack plate 244 is symmetrically slidably disposed in the frame 1. The left end of the second rack plate 244 is fixedly connected to the combing module 5. The second rack plate 244 is meshed with the lower part of the flow-limiting gear 243. The second rack plate 244 moves in the left and right directions with the combing module 5. When the second rack plate 244 meshes with the flow-limiting gear 243, the flow-limiting gear 243 rotates, and the first rack plate 242 meshing with the flow-limiting gear 243 moves in the left and right directions, so that the flow-limiting plate 241 can close or not close the release port 23.

[0026] Reference Figure 4 As shown, the discharge mechanism 25 includes a discharge valve 251, a push-pull plate 252, and a squeezing plate 253. The discharge valve 251 is slidably disposed at the bottom of the release port 23. A return spring is connected between the discharge valve 251 and the release port 23, and the return spring plays a reset role. An L-shaped push-pull plate 252 is installed at the right end of the discharge valve 251. The squeezing plate 253 is slidably disposed in the frame 1 through the combing module 5. The squeezing plate 253 and the push-pull plate 252 are in contact and squeezing fit. The squeezing plate 253 moves with the combing module 5 in the left and right direction. When the squeezing plate 253 moves to the right and contacts and squeezes the push-pull plate 252, the discharge valve 251 is gradually pulled to the right, causing the release port 23 to open. When the squeezing plate 253 moves to the left and no longer squeezes the push-pull plate 252, the discharge valve 251 is reset under the action of the return spring.

[0027] In the actual quantitative release process, the combing module 5 moves from left to right, and the rack plate 244 moves to the right along with the combing module 5. The rack plate 244 gradually contacts and meshes with the flow-limiting gear 243, causing the flow-limiting gear 243 to rotate. The rack plate 242, which is meshed with the flow-limiting gear 243, moves to the left, thereby causing the flow-limiting plate 241 to insert into the release port 23, dividing the release port 23 into two unconnected areas. Then, the rack plate 244 continues to move to the right with the combing module 5, separating from the flow-limiting gear 243. The combing module 5, continuing to move to the right, gradually causes the extrusion plate 253 to contact and extrude with the push-pull plate 252. The discharge valve 251 is pulled to the right, opening the release port 23. The ore located in the lower area of ​​the release port 23 is released. Since the capacity of the lower area of ​​the release port 23 is fixed, the purpose of quantitative release is achieved. Afterwards, the combing module 5 moves from right to left, the squeezing plate 253 no longer squeezes the push-pull plate 252, the discharge valve 251 is reset under the action of the return spring, the rack plate 244 and the flow limiting gear 243 mesh again, the flow limiting gear 243 rotates, the rack plate 242 moves to the right, and the flow limiting plate 241 no longer acts as a separator in the release port 23. Throughout the quantitative release process, the flow limiting plate 241 always separates the discharge valve 251 before opening, and the discharge valve 251 closes first and the flow limiting plate 241 resets later, which ensures the accuracy of ore release and avoids premature ore falling.

[0028] Reference Figure 3 , Figure 8 As shown, the ore varies in size. This application includes a classification module 3 to classify the ore. The classification module 3 includes classification rods 31 and buffer blocks 32. The classification rods 31 are evenly installed in the middle of the vertical pipe 21 along the front-to-back direction. The classification rods 31 are arranged in a gradually downward sloping structure from left to right. The positions of the classification rods 31 correspond to the inclined flow channel 22. When the ore is fed into this application, small ore falls from the gaps between the classification rods 31 into the release port 23, while large ore is intercepted between the classification rods 31 and slides along the inclination angle of the classification rods 31 into the inclined flow channel 22. The classification rods 31 have water channels inside, and the buffer blocks 32 are slidably arranged on the classification rods. At the upper end of 31, a buffer spring is connected between the buffer block 32 and the sorting rod 31. The buffer spring plays a flexible buffering role. The top of the buffer block 32 has a rounded pointed structure. When the falling ore hits the top of the buffer block 32, it will separate to both sides and will not be retained. The buffer block 32 is made of polyurethane and will not have a rigid collision with the ore, reducing the occurrence of ore breakage and splashing. A falling slide groove 321 is opened on the side wall of the buffer block 32 along its length. Water spray holes 322 are evenly inclined in the falling slide groove 321. The water spray holes 322 are connected to the water channel. Water is sprayed out at an angle from the water spray holes 322 to help the ore on the sorting rod 31 slide into the inclined channel 22.

[0029] During the actual sorting process, ores of different sizes fall into the vertical pipe 21 and collide with the buffer block 32. The rounded and pointed structure at the top of the buffer block 32 does not hold small ores. Small ores pass through the gap between the sorting rods 31 and continue to fall. After large ores collide with the buffer block 32, the buffer block 32 buffers the impact of the collision (the buffer block 32 itself is also made of buffering material, ensuring the buffering effect). Large ores are intercepted between the sorting rods 31. Water jets from the spray holes 322 at an angle help the ores on the sorting rods 31 slide into the inclined channel 22.

[0030] Reference Figure 5 As shown, titanium ore is magnetic. This application includes a magnetic separation module 4 to separate titanium ore from non-magnetic stones. The magnetic separation module 4 includes a conveyor group 41, a secondary conveyor group 42, and a high-pressure nozzle 43. The conveyor group 41 is set in the frame 1. The upper surface of the magnetic conveyor group 41 is arranged with the left side higher than the right side. Small ore from the release port 23 falls onto the conveyor group 41. The magnetic conveyor group 41 attracts the equally magnetic titanium ore and moves it upwards, while the non-magnetic stones slide downwards along the upper surface of the conveyor group 41 under the action of gravity, thereby achieving the purpose of separating titanium ore from ordinary stones. The primary conveyor group 42 is located at the right end of the upper surface of the conveyor group 41. The magnetic secondary conveyor group 42 is a certain distance away from the conveyor group 41. The right end of the inclined channel 22 corresponds to the position of the secondary conveyor group 42. The inclined channel 22 transports large ore to the secondary conveyor group 42. The secondary conveyor group 42 screens the titanium ore in the large ore. The screening of small ore and large ore is carried out separately to avoid mutual interference. The high-pressure nozzle 43 is located in the left side wall of the frame 1. The position of the high-pressure nozzle 43 corresponds to the conveyor group 41. The high-pressure water jet sprayed from the high-pressure nozzle 43 washes off the titanium ore adsorbed on the conveyor group 41.

[0031] In the actual magnetic separation process, small ore pieces in the release port 23 fall onto the conveyor group 41. The magnetic conveyor group 41 attracts the titanium ore, which is also magnetic, and moves it upwards. Meanwhile, non-magnetic stones slide downwards along the upper surface of the conveyor group 41 under the action of gravity, thus achieving the purpose of separating titanium ore from ordinary stones. Similarly, the inclined channel 22 transports large ore to the secondary conveyor group 42. The secondary conveyor group 42 screens the titanium ore in the large ore. Magnetic titanium ore is screened out and transported to the leftmost end of the conveyor group 41. Then, high-pressure water jets from the high-pressure nozzle 43 wash the titanium ore off the conveyor group 41 and drop it to the designated position.

[0032] Reference Figure 9 , Figure 10As shown, small ores may not be selected during magnetic separation due to uneven accumulation. This application provides a combing module 5 to flatten the small ores selected by magnetic separation. The combing module 5 includes a guide rail 51, a combing component 52, a crossbar 53, a locking mechanism 54, a reset block 55, and an air blowing mechanism 56. The guide rail 51 is installed in the frame 1, and the angle of the guide rail 51 is consistent with the angle of the conveyor group 41. The combing component 52 is slidably mounted on the guide rail 51 via a drive slider. The combing component 52 flips and combs the small ores on the conveyor group 41, making them evenly spread on the surface of the conveyor group 41, thereby... The titanium ore makes more comprehensive contact with the conveyor group 41 and is attracted by magnetism, improving the screening rate of titanium ore. The crossbar 53 is installed at the left end of the guide rail 51. The locking mechanism 54 is located inside the combing assembly 52. ​​When the combing assembly 52 moves to the leftmost position, it is squeezed by the crossbar 53 to adjust the angle. The locking mechanism 54 temporarily locks the angle of the combing assembly 52. ​​The reset block 55 is installed at the right end of the guide rail 51. The inner side of the reset block 55 is an angled structure. The reset block 55 unlocks the angle of the combing assembly 52. ​​The air blowing mechanism 56 is located inside the combing assembly 52.

[0033] Reference Figure 10 As shown, the combing assembly 52 includes an angle plate 521, a sliding block 522, and a combing plate 524. The angle plate 521 is rotatably mounted in the sliding block 522 via a pin. A torque spring connects the angle plate 521 and the sliding block 522, which keeps the angle plate 521 at a certain angle to the guide rail 51. The sliding block 522 is slidably mounted on the guide rail 51 via a drive slider. The lower end of the angle plate 521 has evenly spaced inclined open slots. The lower surface of the angle plate 521 has evenly spaced air blowing holes 523, which are connected to the air blowing mechanism 56. The combing plate 524 is rotatably mounted in the open slots. A compression spring connects the combing plate 524 and the open slots, which serves as a reset mechanism. The surface of the combing plate 524 has air blowing holes 525, which are connected to the air blowing mechanism 56.

[0034] During the actual combing process, the drive slider moves the combing assembly 52 from right to left on the guide rail 51. The inclined combing plate 524 contacts and compresses the small ore particles, which, combined with the gas ejected from the second air blowhole 525, physically agitates the small ore particles. The small ore particles are then evenly spread on the conveyor group 41, and the angle plate 521 adsorbs some of the titanium ore particles near the upper layer. The combing assembly 52 gradually moves to contact the crossbar 53 and compresses it. The angle plate 521 is compressed until its angle matches that of the guide rail 51, and the combing plate 524 is... The compression and rotation retracts into the open slot, and the locking mechanism 54 locks the position of the angle plate 521 at this time. During the rotation of the combing plate 524, the air blowing mechanism 56 is triggered to switch, the air blowing in the second air blowing hole 525 disappears, and the air blowing operation begins in the first air blowing hole 523. At this time, the magnetism of the angle plate 521 disappears, and the titanium ore adsorbed by the angle plate 521 loses its adsorption force and falls. While the crossbar 53 is squeezing the angle plate 521, it also scrapes the bottom surface of the angle plate 521. With the air blowing action of the first air blowing hole 523, the titanium ore is ensured to fall smoothly.

[0035] Reference Figure 10 , Figure 11 As shown, to prevent the angle plate 521 from scraping against the ore during retraction, this application provides a locking mechanism 54 to temporarily lock the angle plate 521 after angle adjustment. The locking mechanism 54 includes a snap-fit ​​component 541, an auxiliary rod 542, a compression spring 543, and a locking component 544. The snap-fit ​​component 541 is symmetrically slidably disposed in the angle plate 521. The auxiliary rod 542 is installed at the rear end of the U-shaped snap-fit ​​component 541. The compression spring 543, located between the auxiliary rods 542, is disposed in the angle plate 521. The compression spring 543 always maintains an outward pushing tendency on the auxiliary rod 542. A locking groove is provided at the lower end of the auxiliary rod 542. The right end of the locking component 544 is fixedly connected to the combing plate 524. The position of the locking component 544 corresponds to the locking groove. The locking component 544 is inserted into the locking groove to temporarily lock the position of the auxiliary rod 542.

[0036] During the actual locking process, the combing plate 524 contacts and rotates with the crossbar 53. The rotating combing plate 524 drives the locking member 544 to disengage from the locking groove. Under the action of the compression spring 543, the auxiliary rod 542 slides outward (the locking member 544 is misaligned with the locking groove), so that the snap-fit ​​member 541 snaps into the guide rail 51 (at this time, the angle plate 521 has been squeezed to the same angle as the guide rail 51), and the position of the angle plate 521 is locked. When the combing assembly 52 moves to the right, the right end of the snap-fit ​​member 541 gradually contacts and squeezes with the reset block 55. The snap-fit ​​member 541 is squeezed to disengage from the guide rail 51. Under the action of the torque spring, the angle plate 521 rotates and resets. At the same time, the snap-fit ​​member 541 moves inward so that the position between the locking groove and the locking member 544 corresponds. Under the action of the compression spring, the combing plate 524 resets and rotates, and the locking member 544 is inserted into the locking groove to lock the position of the auxiliary rod 542.

[0037] Reference Figure 11 , Figure 12 As shown, this application includes an air blowing mechanism 56 for air blowing and turning small ore particles and assisting in unloading. The air blowing mechanism 56 includes an air pump 561, a valve body 562, a partition plate 566, and a push rod 567. The air pump 561 is installed on the upper surface of the angle plate 521, and the valve body 562 is also installed on the upper surface of the angle plate 521. The valve body 562 has a hollow structure. From top to bottom, the side wall of the valve body 562 has an air outlet 563, an air inlet 564, and an air outlet 565. The air inlet 564 is connected to the air pump 561, the air outlet 563 is connected to the air blowing hole 523, and the air outlet 565 is connected to the air blowing hole 525. The partition plate 566 is slidably disposed inside the valve body 562. The partition plate 566 and the valve body 562 are connected. A return spring is connected between the two parts, which plays a reset role. A push rod 567 is installed at the bottom of the partition plate 566. The position of the push rod 567 corresponds to that of the combing plate 524. In the initial state, the partition plate 566 is located at the bottom of the valve body 562 (at this time, the partition plate 566 is lower than the air inlet 564). At this time, the second air outlet 565 is blocked, and the air inlet 564 and the first air outlet 563 are in a connected state. The first air blowing hole 523 performs air blowing operation. When the push rod 567 is squeezed, the partition plate 566 is pushed to the top of the valve body 562 (at this time, the partition plate 566 is higher than the air inlet 564). At this time, the first air outlet 563 is blocked, and the air inlet 564 and the second air outlet 565 are in a connected state. The second air blowing hole 525 performs air blowing operation.

[0038] During the actual air blowing process, the initial state of the partition plate 566 is located at the bottom of the valve body 562. At this time, the second air outlet 565 is blocked, and the air inlet 564 and the first air outlet 563 are in a connected state. The first air blowing hole 523 performs air blowing operation. When the combing plate 524 contacts the crossbar 53 and rotates, the rotating combing plate 524 squeezes the push rod 567 to move upward. The partition plate 566 is pushed to the top of the valve body 562. At this time, the first air outlet 563 is blocked, and the air inlet 564 and the second air outlet 565 are in a connected state. The second air blowing hole 525 performs air blowing operation.

[0039] The implementation principle of this embodiment is as follows: Step 1: Put the ore to be screened into the feed module 2; Step 2: Classification module 3 transports large ores to secondary conveyor group 42 and small ores to conveyor group 41 according to their size. Step 3: Large ore is magnetically separated on the secondary conveyor group 42. Magnetic large titanium ore rises continuously from right to left on the secondary conveyor group 42, while non-magnetic large ore falls continuously from left to right on the secondary conveyor group 42, thereby achieving the separation of large titanium ore. Small ore is magnetically separated on the conveyor group 41. Magnetic small titanium ore rises continuously from right to left on the conveyor group 41, while non-magnetic small titanium ore falls continuously from left to right on the conveyor group 41, thereby achieving the separation of small titanium ore. Step 4: The sorting module 5 continuously blows air to agitate and physically turn the small ore in the magnetic separation, so that the small ore is evenly spread on the conveyor group 41, and performs secondary magnetic separation on the small ore, thereby improving the accuracy of ore screening. Step 5: The titanium ore that has undergone magnetic separation is flushed to the designated location by the high-pressure nozzle 43.
