Description

Technical Field

[0001] This invention belongs to the technical field of ore conveying and material sorting equipment, specifically relating to an automatic iron removal device for materials in a belt conveyor. Background Technology

[0002] Belt conveyors are common continuous conveying equipment widely used in the transportation of materials such as ores, coal, and sand. They primarily transport materials from one location to another through the continuous operation of the conveyor belt, featuring long conveying distances, large conveying capacities, and the ability to operate continuously. During ore transportation, due to the effects of mining, crushing, and loading processes, iron blocks, iron wires, and other iron-containing impurities may be mixed into the ore. These impurities, when entering subsequent crushing and screening equipment, can easily damage the equipment. Therefore, iron removal treatment is usually required during the conveying process.

[0003] Existing methods for removing iron from belt conveyors typically involve installing magnetic iron removal devices above the conveyor belt to attract iron impurities from the material using magnetic force, or manually picking out iron-containing materials from the conveyor belt. However, when using these methods, some iron-containing ore can be obscured by surrounding materials during continuous operation and when the material volume is large, preventing timely detection or adsorption of iron impurities. Furthermore, some existing iron removal devices require shutdown for cleaning and processing when handling high iron content or large volumes of iron-containing materials, affecting the continuous operation of the belt conveyor, reducing overall conveying efficiency, and manual processing is labor-intensive. Therefore, current technologies struggle to effectively and promptly remove iron-containing ore during the conveying process while ensuring the normal continuous operation of the belt conveyor.

[0004] Based on the above problems, it is necessary to provide an automatic iron removal device for materials in a belt conveyor. By detecting materials during the normal operation of the belt conveyor, and automatically removing the corresponding materials from the conveyor belt after detecting iron-containing ore or iron materials, the iron-containing materials can be separated in a timely manner without stopping the machine, thereby reducing manual operation and downtime, and improving the iron removal efficiency of the belt conveyor during operation. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic iron removal device for materials in belt conveyors, which solves the problem that iron-containing materials mixed in with the material are difficult to detect and remove in a timely manner during the conveying of ore in existing belt conveyors, and that the conveying efficiency is affected by the need to stop the machine for cleaning or manual handling. The invention enables iron-containing ore to be automatically detected and removed while the belt conveyor is running normally, thereby reducing manual operation and equipment downtime, and improving the iron removal efficiency during the material conveying process.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: The device includes a conveyor, a pre-crushing component, a detection component, and an iron removal component. These components are sequentially arranged above the conveyor along its conveying direction. The iron removal component includes an iron removal bracket, baffles, and a pusher plate. The iron removal bracket is mounted on the conveyor. Two baffles are provided, located on opposite sides of the conveyor along its conveying direction and slidably connected to the iron removal bracket vertically. A discharge port is provided on the conveyor corresponding to the position of the iron removal bracket. The pusher plate is located between the two baffles and slidably connected to the iron removal bracket. The iron removal component also includes a drive module connected to both baffles and the pusher plate. The drive module drives the two baffles to move vertically and drives the pusher plate to move towards or away from the discharge port.

[0007] In this structural design, the ore is conveyed forward along the conveyor. When the detection component detects that the ore contains metal, the drive module starts and simultaneously drives two baffles and a pusher plate to move. The two baffles move vertically to their working positions on both sides of the conveyor belt, limiting the conveying range of the ore. At the same time, the pusher plate moves towards the discharge port, pushing the detected metal-containing ore towards the discharge port, causing it to detach from the conveyor and fall down, while other normal ore continues to be conveyed forward with the conveyor belt. After the rejection is completed, the drive module drives the two baffles and pusher plate to reset, thus realizing the automatic rejection of metal-containing ore without stopping the conveyor.

[0008] The drive module includes a drive motor, a synchronous transmission structure, a first rotating shaft, a reversing mechanism, a second rotating shaft, and a drive wheel. The drive motor is mounted on the iron removal bracket. There are two first rotating shafts, both of which are rotatably connected to the iron removal bracket. Each first rotating shaft is a screw. The drive motor is driven by one of the first rotating shafts. The two first rotating shafts are driven by the synchronous transmission structure. The tops of the two baffles are connected by a connecting plate. The connecting plate is threaded into the two first rotating shafts respectively. The second rotating shaft is driven by the first rotating shaft connected to the drive motor through the reversing mechanism. The drive wheel is coaxially connected to the second rotating shaft and driven by the push plate.

[0009] In this structural design, when the drive motor is working, it drives one of the first shafts, which acts as a screw, to rotate. Through a synchronous transmission structure, it drives the other first shaft to rotate synchronously, so that the two first shafts are threaded into the connecting plate, thereby moving the connecting plate vertically and causing the two baffles to rise and fall synchronously. At the same time, the first shaft driven by the drive motor transmits power to the second shaft through a reversing mechanism, causing the second shaft to drive the drive wheel to rotate. The drive wheel drives the push plate to move horizontally through a rack and pinion. Thus, a single drive motor can drive the movement of two baffles and the push plate simultaneously, reducing the number of drive devices and lowering operating energy consumption.

[0010] The push plate is provided with a rack that meshes with the drive wheel, and the rack is slidably disposed within the iron removal bracket along the moving direction of the push plate.

[0011] With this structural design, when the second rotating shaft rotates, it drives the drive wheel to rotate. The drive wheel meshes with the rack, causing the rack to slide along the iron removal bracket, which in turn causes the push plate connected to the rack to reciprocate along its moving direction. When the drive wheel rotates in the corresponding direction, the push plate moves toward the discharge port, pushing the metal-containing ore into the discharge port. When the drive wheel rotates in the opposite direction, the push plate moves away from the discharge port and resets, thus achieving stable movement of the push plate.

[0012] A guide chute is provided on the side of the iron removal bracket near the material discharge port, and the guide chute extends outward from the conveyor.

[0013] With this structural design, the metal-containing ore pushed out by the push plate falls from the discharge port into the guide chute and moves along the guide chute to the outside of the conveyor, so that the rejected ore can be discharged in a concentrated manner, avoiding the ore from falling directly near the conveyor and affecting the operation of subsequent equipment. At the same time, it is convenient to collect and process the metal-containing ore in a concentrated manner.

[0014] The pre-crushing assembly includes a pre-crushing bracket, a screening frame, a lifting motor, and extrusion blocks. The pre-crushing bracket is mounted on the conveyor. The screening frame is located above and spaced apart from the conveyor belt. The lifting motor is located on top of the pre-crushing bracket, and its output is connected to the screening frame to drive the screening frame to move vertically up and down. Two extrusion blocks are provided, located on opposite sides of the screening frame. Each extrusion block is connected to a driving device, which drives the two extrusion blocks to move closer to or further away from each other.

[0015] With this structural design, after the ore enters the screening frame, the lifting motor drives the screening frame to move vertically, allowing smaller pieces of ore to fall through the screening frame onto the conveyor belt, while larger pieces of ore remain temporarily inside the screening frame. Subsequently, the drive unit moves two extrusion blocks located on both sides of the screening frame closer together to crush the larger pieces of ore remaining in the screening frame. The crushed ore then falls onto the conveyor belt and continues to be transported forward with the conveyor. This pre-processing of larger pieces of ore during the conveying process reduces the amount of large material in the subsequent ore shipments.

[0016] The screening frame has multiple screening ports, and the screening frame has a feed port on one side along the conveying direction of the conveyor. The pre-crushing component also includes an intercepting net that is slidably disposed on the pre-crushing support and located on one side of the feed port. A steel rope is connected to the top of the intercepting net. A pulley is fixedly disposed on the pre-crushing support. The steel rope is wound around the pulley, and the end of the steel rope away from the intercepting net is fixedly connected to the screening frame.

[0017] In this structural design, after the ore enters the screening frame through the feed inlet, the screening frame moves upward under the action of the lifting motor. The screening frame drives the intercepting net to move in the opposite direction through steel ropes and pulleys, causing the intercepting net to descend and block the feed inlet, thereby reducing the occurrence of ore falling out of the feed inlet during the screening process. The multiple screening ports on the screening frame allow smaller pieces of ore to fall onto the conveyor belt as the screening frame moves upward, while larger pieces of ore remain in the screening frame for subsequent crushing. When the screening frame returns to its original position, the steel rope drives the intercepting net upward again, reopening the feed inlet to allow subsequent ore to enter.

[0018] The detection assembly includes a detection bracket and a detection module. The detection bracket is mounted on the conveyor, and the detection module is positioned above the conveyor belt of the conveyor. The detection module is used to detect whether the ore on the conveyor contains metal. When the detection module detects that the ore contains metal, it controls the iron removal assembly to start in order to remove the metal from the ore.

[0019] With this structural design, when the ore passes through the detection module on the conveyor belt, the detection module detects the ore passing through the detection area. When metal is detected in the ore, the detection module sends a control signal to the iron removal component, causing the iron removal component to start and remove the metal-containing ore at the corresponding position. The ore for which no metal is detected continues to be conveyed forward with the conveyor belt. This allows for automatic iron removal based on the detection results, reducing manual sorting operations and improving the continuity of the iron removal process.

[0020] The invention employing the above technical solution has the following advantages: 1. By setting up detection and iron removal components, the ore in the conveying process can be detected. After detecting iron-containing ore, the iron-containing ore is guided to the discharge port for removal by baffles and push plates. This allows the iron-containing ore to be automatically detected and removed while the belt conveyor is running normally, without the need to stop the machine for cleaning. It also reduces the need for manual handling, thereby reducing the number of equipment downtimes and improving the iron removal efficiency and continuous conveying capacity during the material conveying process.

[0021] 2. By driving two baffles and push plates simultaneously through a single drive module, and through the cooperation between the first rotating shaft, synchronous transmission structure, reversing mechanism, second rotating shaft and drive wheel, the baffles and push plates can complete their corresponding actions using the same driving power. Compared with setting multiple drive devices separately, this reduces the number of drive devices used and reduces the energy consumption of the equipment while ensuring the normal operation of the iron removal process.

[0022] 3. By setting up a pre-crushing component, the ore is first screened by a screening frame to separate ore of different sizes before testing and iron removal. Two extrusion blocks then crush the larger ore pieces screened out, allowing smaller pieces to fall directly through the screening frame to the conveyor, while larger pieces are crushed before being conveyed. This reduces the impact of large pieces of ore on subsequent testing and iron removal processes, improving the stability of the ore conveying process. Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0025] like Figures 1-7 As shown, an automatic iron removal device for materials in a belt conveyor according to the present invention includes: a conveyor 1, a pre-crushing component 2, a detection component 3, and an iron removal component 4. The pre-crushing component 2, the detection component 3, and the iron removal component 4 are sequentially arranged above the conveyor 1 along the conveying direction of the conveyor 1. The iron removal component 4 includes an iron removal bracket 41, baffles 42, and push plates 43. The iron removal bracket 41 is mounted on the conveyor 1. Two baffles 42 are provided, which are located on both sides of the conveyor 1 along the conveying direction and are slidably connected to the iron removal bracket 41 in the vertical direction. The conveyor 1 has a discharge port 11 at the position corresponding to the iron removal bracket 41. The push plate 43 is located between the two baffles 42 and is slidably connected to the iron removal bracket 41. The iron removal component 4 also includes a drive module 5, which is connected to the two baffles 42 and the push plate 43 respectively. The drive module 5 is used to drive the two baffles 42 to move in the vertical direction and drive the push plate 43 to move toward or away from the discharge port 11.

[0026] In practice, depending on the actual situation, the iron removal component 4 can also adopt other drive structures that can synchronously drive the baffle 42 and push plate 43 to move. In this embodiment, the ore is conveyed forward along the conveyor 1. When the detection component 3 detects that the ore contains metal, the drive module 5 starts and simultaneously drives the two baffles 42 and push plate 43 to move. The two baffles 42 move vertically to the working positions on both sides of the conveyor belt to limit the conveying range of the ore. At the same time, the push plate 43 moves towards the discharge port 11 to push the detected metal-containing ore towards the discharge port 11, so that it is removed from the conveyor 1 and falls down, while other normal ore continues to be conveyed forward with the conveyor belt. After the removal is completed, the drive module 5 drives the two baffles 42 and push plate 43 to reset, thereby realizing the automatic removal of metal-containing ore without stopping the conveyor 1.

[0027] The drive module 5 includes a drive motor 51, a synchronous transmission structure 52, a first rotating shaft 53, a reversing mechanism 54, a second rotating shaft 55, and a drive wheel 56. The drive motor 51 is mounted on the iron removal bracket 41. There are two first rotating shafts 53, both of which are rotatably connected to the iron removal bracket 41. The first rotating shaft 53 is a screw. The drive motor 51 is driven by one of the first rotating shafts 53. The two first rotating shafts 53 are driven by the synchronous transmission structure 52. The tops of the two baffles 42 are connected by a connecting plate 45. The connecting plate 45 is threaded to the two first rotating shafts 53 respectively. The second rotating shaft 55 is driven by the first rotating shaft 53 connected to the drive motor 51 through the reversing mechanism 54. The drive wheel 56 is coaxially connected to the second rotating shaft 55 and is driven by the push plate 43.

[0028] In practice, depending on the actual situation, the first rotating shaft 53 can also adopt other transmission structures that can drive the connecting plate 45 to move up and down. In this embodiment, when the drive motor 51 is working, it drives one of the first rotating shafts 53, which acts as a screw, to rotate. It also drives the other first rotating shaft 53 to rotate synchronously through the synchronous transmission structure 52. The two first rotating shafts 53 are threadedly engaged with the connecting plate 45, thereby causing the connecting plate 45 to move vertically and drive the two baffles 42 to rise and fall synchronously. At the same time, the first rotating shaft 53 driven by the drive motor 51 transmits power to the second rotating shaft 55 through the reversing mechanism 54. The second rotating shaft 55 drives the drive wheel 56 to rotate. The drive wheel 56 drives the push plate 43 to move horizontally through the rack 46. Thus, the two baffles 42 and the push plate 43 are driven to move simultaneously by one drive motor 51, reducing the number of drive devices and reducing operating energy consumption.

[0029] The push plate 43 is provided with a rack 46 that meshes with the drive wheel 56. The rack 46 is slidably disposed in the iron removal bracket 41 along the moving direction of the push plate 43.

[0030] In practice, depending on the actual situation, other connection structures that can achieve linear transmission can also be used between the push plate 43 and the drive wheel 56. In this embodiment, when the second rotating shaft 55 rotates, it drives the drive wheel 56 to rotate. The drive wheel 56 drives the rack 46 to slide along the iron removal bracket 41 through meshing with the rack 46, thereby causing the push plate 43 connected to the rack 46 to reciprocate along its moving direction. When the drive wheel 56 rotates in the corresponding direction, the push plate 43 moves toward the discharge port 11 and pushes the metal-containing ore into the discharge port 11. When the drive wheel 56 rotates in the opposite direction, the push plate 43 moves away from the discharge port 11 and resets, thereby achieving stable movement of the push plate 43.

[0031] A guide chute 44 is provided on the side of the iron removal bracket 41 near the material discharge port 11, and the guide chute 44 extends outward from the conveyor 1.

[0032] In practice, depending on the actual situation, the guide trough 44 can also adopt other structures that can guide the rejected ore. In this embodiment, the metal-containing ore pushed out by the push plate 43 falls from the discharge port 11 and enters the guide trough 44, and moves along the guide trough 44 to the outside of the conveyor 1, so that the rejected ore can be discharged in a concentrated manner, avoiding the ore from falling directly near the conveyor 1 and affecting the operation of subsequent equipment, while facilitating the centralized collection and processing of the metal-containing ore.

[0033] The pre-crushing component 2 includes a pre-crushing support 21, a screening frame 22, a lifting motor 23, and an extrusion block 24. The pre-crushing support 21 is mounted on the conveyor 1. The screening frame 22 is located above the conveyor belt of the conveyor 1 and is spaced apart from the conveyor belt. The lifting motor 23 is located on the top of the pre-crushing support 21. The output end of the lifting motor 23 is connected to the screening frame 22 to drive the screening frame 22 to move up and down in the vertical direction. There are two extrusion blocks 24, which are located on opposite sides of the screening frame 22. Both extrusion blocks 24 are connected to a driving device, which is used to drive the two extrusion blocks 24 to move closer or further apart from each other.

[0034] In practice, depending on the actual situation, the pre-crushing component 2 can also adopt other structures that can screen and crush large pieces of ore. In this embodiment, after the ore enters the screening frame 22, the lifting motor 23 drives the screening frame 22 to move vertically, so that smaller pieces of ore can fall down onto the conveyor belt through the screening frame 22, while larger pieces of ore remain temporarily in the screening frame 22. Subsequently, the driving device drives the two extrusion blocks 24 located on both sides of the screening frame 22 to move closer to each other, and to crush the large pieces of ore remaining in the screening frame 22. The crushed ore then falls onto the conveyor belt and continues to be conveyed forward with the conveyor 1, thereby pre-processing the larger pieces of ore during the conveying process and reducing the amount of large pieces of material in the subsequent ore.

[0035] The screening frame 22 has multiple screening ports 25. The screening frame 22 has a feed port 26 on one side along the conveying direction of the conveyor 1. The pre-crushing component 2 also includes an intercepting net 27 that is slidably mounted on the pre-crushing bracket 21 and located on one side of the feed port 26. A steel rope 28 is connected to the top of the intercepting net 27. A pulley 29 is fixedly mounted on the pre-crushing bracket 21. The steel rope 28 is wound around the pulley 29, and the end of the steel rope 28 away from the intercepting net 27 is fixedly connected to the screening frame 22.

[0036] In practice, depending on the actual situation, the intercepting net 27 can also adopt other linkage structures that can open and close the feed inlet 26 as the screening frame 22 rises and falls. In this embodiment, after the ore enters the screening frame 22 through the feed inlet 26, the screening frame 22 moves upward under the action of the lifting motor 23. The screening frame 22 drives the intercepting net 27 to move in the opposite direction through the steel rope 28 and pulley 29, so that the intercepting net 27 descends and blocks the feed inlet 26, thereby reducing the situation where the ore falls out of the feed inlet 26 during the screening process. The multiple screening ports 25 on the screening frame 22 allow smaller ore to fall onto the conveyor belt during the upward movement of the screening frame 22, while larger ore remains in the screening frame 22 for subsequent crushing. When the screening frame 22 resets downward, the steel rope 28 drives the intercepting net 27 to move upward again, so that the feed inlet 26 reopens to allow subsequent ore to enter.

[0037] The detection component 3 includes a detection bracket 31 and a detection module 32. The detection bracket 31 is mounted on the conveyor 1, and the detection module 32 is positioned above the conveyor belt of the conveyor 1. The detection module 32 is used to detect whether the ore on the conveyor 1 contains metal. When the detection module 32 detects that the ore contains metal, it controls the iron removal component 4 to start so as to remove the metal from the ore.

[0038] In practice, depending on the actual situation, the detection component 3 can also adopt other detection structures that can detect metals in ore and output control signals. In this embodiment, when the ore passes through the detection module 32 on the conveyor belt, the detection module 32 detects the ore passing through the detection area. When metal is detected in the ore, the detection module 32 sends a control signal to the iron removal component 4, causing the iron removal component 4 to start and remove the metal-containing ore at the corresponding position. The ore for which no metal is detected continues to be conveyed forward with the conveyor belt, thereby enabling automatic iron removal based on the detection results, reducing manual sorting operations and improving the continuity of the iron removal process.

[0039] In this embodiment, during operation, the ore is first conveyed forward by the conveyor 1 and enters the screening frame 22 of the pre-crushing component 2. The lifting motor 23 drives the screening frame 22 to rise and fall vertically, allowing smaller pieces of ore to fall through the discharge port 11 onto the conveyor belt, while larger pieces remain in the screening frame 22. Simultaneously, the screening frame 22, via the steel rope 28 and pulley 29, moves the intercepting net 27 up and down, blocking the feed port 26 during the screening process to reduce ore falling out. Subsequently, two extrusion blocks 24 approach each other, crushing the large pieces of ore in the screening frame 22. The crushed ore falls onto the conveyor belt and continues to be conveyed. When the ore passes through the detection component 3, the detector... The detection module 32 detects the ore. When it detects ore containing metal, it controls the iron removal component 4 to start. The drive motor 51 drives the first rotating shaft 53 to rotate, and the synchronous transmission structure 52 makes the two first rotating shafts 53 rotate synchronously, driving the connecting plate 45 and the two baffles 42 to move synchronously. At the same time, the reversing mechanism 54 drives the second rotating shaft 55 and the drive wheel 56 to rotate. The drive wheel 56 drives the push plate 43 to move towards the discharge port 11 through the rack 46, pushing the metal-containing ore into the discharge port 11 and discharging it through the guide chute 44. After the removal is completed, the drive motor 51 runs in reverse, causing the baffles 42 and the push plate 43 to reset, and the normal ore continues to be conveyed along the conveyor 1.

The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention.
