Description

Technical Field

[0001] This invention relates to the field of coal mining technology, and more specifically to an iron removal device. Background Technology

[0002] During coal mining, coal often contains metal objects of various shapes and sizes, which need to be removed from the coal flow to prevent damage to subsequent equipment and conveyors. To avoid damage to equipment, a metal removal device is typically installed above the coal chute at the conveyor head to adsorb the metal objects in the coal flow. However, the adsorption capacity of the metal removal device is limited. When it is necessary to remove the metal objects from the device, the machine must be stopped, wooden boards must be laid on top of the coal chute, the power to the metal removal device must be turned off, and then manual removal of the metal is required. Most conveyors are equipped with a delayed start function, which makes the time between removing the metal objects from the device and restarting the conveyor even longer, affecting the conveyor's transport efficiency. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide an iron removal device that can automatically remove iron, ensuring the conveying efficiency of the conveyor.

[0004] The iron removal device of this invention includes: a support assembly, the support assembly including a first support member, the first support member being an annular support member, and a slide rail provided on the first support member; an iron removal assembly, the iron removal assembly including an iron remover and a connecting member, one end of the connecting member being connected to the end of the iron remover away from the coal flow, and the other end of the connecting member being slidably connected to the slide rail so that the iron remover can move relative to the slide rail, the number of iron removal assemblies being multiple, the multiple iron removal assemblies being arranged at intervals on the annular support member, and the multiple iron removal assemblies being independent of each other; a level detector, the level detector being disposed on the iron remover, the level detector being used to detect the angle between the iron remover and the horizontal line; a camera, the camera being mounted on the support assembly, the camera being used to measure the size of the iron adsorbed by the iron remover; and a central controller, the central controller being connected to the level detector, the camera and the iron removal assembly respectively, the level detector and the camera transmitting real-time detected data to the central controller, and the central controller adjusting the position of the iron removal assembly according to the real-time data transmitted by the level detector and the camera.

[0005] The iron removal device of this invention can automatically remove iron, ensuring the conveying efficiency of the conveyor.

[0006] In some embodiments, when the iron removal assembly begins to adsorb iron objects in the coal stream, the central controller compares the real-time size S1 of the iron object captured by the camera with a size reference value S0. S1 is the real-time size of the iron object captured by the camera, and the central controller contains the size reference value S0.

[0007] If S1≥S0, the central controller controls the current iron removal component to move away from the coal flow, and at the same time controls another iron removal component adjacent to the current iron removal component to move towards the coal flow and move to directly above the coal flow.

[0008] If S1 < S0, the central controller will not adjust the current working state of the iron removal component.

[0009] In some embodiments, when the real-time size of the iron object captured by the camera is smaller than a size reference value, the angle between the iron remover detected by the leveling instrument and the horizontal line is set to A, and the angle reference value is set to A0 in the central controller. The controller compares the angle A between the iron remover detected by the leveling instrument and the horizontal line with the angle reference value A0.

[0010] If A≥A0, the central controller controls the current iron removal component to move away from the coal flow, and at the same time controls another iron removal component adjacent to the current iron removal component to move towards the coal flow and move to directly above the coal flow.

[0011] If A < A0, the central controller will not adjust the current working state of the iron removal component.

[0012] In some embodiments, when the angle between the iron remover and the horizontal line detected by the leveling instrument is less than an angle reference value, the central controller compares the current working time of the iron removal component with a time reference value, sets the current working time of the iron removal component as T, and sets the time reference value to T0 within the central controller.

[0013] If T≥T0, the central controller controls the current iron removal component to move away from the coal flow, and at the same time controls another iron removal component adjacent to the current iron removal component to move towards the coal flow and move to directly above the coal flow.

[0014] If T < T0, the central controller will not adjust the current working state of the iron removal component, and the central controller will compare the real-time size of the iron object captured by the camera with the size reference value.

[0015] In some embodiments, the iron separator is provided with a connecting lug at the end away from the coal flow, and the number of the connecting lugs is set to multiple, with the multiple connecting lugs arranged at intervals along the length direction of the iron separator, and the connecting lugs being connected to a connecting component.

[0016] In some embodiments, the connecting component includes a pulley block and a circular chain, the pulley block cooperating with the slide rail, one end of the circular chain being connected to one of the two adjacent connecting lugs, and the other end of the circular chain passing through the pulley block and being connected to the other connecting lug.

[0017] In some embodiments, the number of connecting components is multiple, and the multiple connecting components are arranged at intervals in the extension direction of the slide rail.

[0018] In some embodiments, the support assembly further includes a second support member, one end of which is adapted to be connected to the ground, and the other end of which is connected to the first support member to fix the position of the first support member.

[0019] In some embodiments, the iron removal device further includes a collector located below the annular support and spaced apart from the coal flow.

[0020] In some embodiments, when the central controller controls the current iron removal assembly to move away from the coal flow, the central controller controls the current iron removal assembly to move above the collector and then cuts off the power to the current iron removal assembly.

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The iron removal device of this invention includes a support assembly 1, an iron removal assembly 2, a level detector 3, a camera, and a central controller 4. The support assembly 1 includes a first support member 11, which is an annular support member, and a slide rail 111 is provided on the first support member 11. The iron removal assembly 2 includes an iron remover 21 and a connecting member 22. One end of the connecting member 22 is connected to the end of the iron remover 21 away from the coal flow 100, and the other end of the connecting member 22 is slidably connected to the slide rail 111 so that the iron remover 21 can move relative to the slide rail 111. Multiple iron removal assemblies 2 are arranged at intervals on the annular support member, and are independent of each other. The level detector 3 is mounted on the iron remover 21 and is used to detect the angle between the iron remover 21 and the horizontal line. A camera (not shown in the figure) is mounted on the support assembly 1 and is used to measure the size of the iron objects 200 adsorbed by the iron remover 21. The central controller 4 is connected to the level detector 3, the camera, and the iron removal component 2. The level detector 3 and the camera transmit the real-time data they detect to the central controller 4, and adjust the position of the iron removal component 2 based on the real-time data transmitted by the level detector 3 and the camera.

[0032] It should be noted that manual iron removal refers to workers laying wooden boards on the top of the coal chute below the iron separator 21 at the head of the belt conveyor. After the iron separator 21 is de-energized, the iron objects 200 spontaneously combust and fall onto the wooden boards in a non-magnetic state. Workers then move the iron objects 200 to a designated location, clean them up, remove the wooden boards, and restart the iron separator 21. However, this method requires the machine to be stopped for iron removal when removing iron objects 200 from the coal flow 100, which poses a high risk to workers and affects the conveyor's conveying efficiency.

[0033] Specifically, such as Figures 1-2As shown, the first support member 11 extends in the left-right direction, and the lower end of the first support member 11 is provided with a slide rail 111. The iron separator 21 is an electromagnetic iron separator 21. The connecting member 22 connects the iron separator 21 and the first support member 11. That is, the upper end of the connecting member 22 is connected to the slide rail 111, and the lower end of the connecting member 22 is connected to the upper end of the iron separator 21. The connecting member 22 can slide on the slide rail 111, so that the iron separator 21 can move relative to the slide rail 111 along the extension direction of the slide rail 111, thereby realizing the sliding of the iron separator 21 from the position of the coal flow 100 to the position of the collector 5. The number of iron removal components 2 is set to multiple. In this embodiment, the number of iron removal components 2 is two. The two iron removal components 2 are arranged at intervals in the left-right direction. The iron removal component 2 on the left is located above the collector 5, and the iron removal component 2 on the right is located above the conveyor, that is, directly above the coal flow 100. The level detector 3 is located directly above the iron remover 21, which facilitates the level detector 3 to measure the angle between the iron remover 21 and the horizontal line and transmit the measured angle to the central controller 4. The camera is installed on the support assembly 1. The camera takes pictures of the iron objects 200 adsorbed on the iron remover 21 and identifies the largest size of the iron objects 200 and transmits it to the central controller 4.

[0034] The central controller 4 controls the position of the right-side iron separator 21, adjusting it so that it is directly above the coal flow 100. The iron separator 21 is then energized to generate a magnetic field, attracting iron objects 200 from the coal flow 100. The iron removal assembly 2 is mounted on a ring support, and the slide rail 111 ensures the smooth movement of the assembly 2. When the central controller 4 determines that iron removal from the iron separator 21 is necessary, it slides the right-side iron separator 21 along the track to the left, above the collector 5, and de-energizes it. This causes the iron objects 200 attracted to the iron separator 21 to fall into the iron removal area collector 5. After processing, the central controller 4 controls the position of the iron separator 21 again, moving it along the slide rail 111. By controlling the positions of the two iron separators 21, the central controller 4 achieves the attraction and removal of iron objects 200 from the coal flow 100 and the removal of iron objects 200 from the iron separators 21 without stopping the conveyor, ensuring the conveyor's efficiency.

[0035] In this embodiment of the invention, the left iron separator 21 is located above the collector 5. Automatic iron removal by de-energizing the left iron separator 21 is achieved. The right iron separator 21 is located directly above the coal stream 100 and adsorbs iron objects 200 in the coal stream 100. Both the left and right iron separators 21 are slidably connected to the slide rail 111. By adjusting the positions of the two iron separators 21, the left iron separator 21 remains de-energized after automatic iron removal and moves along the track to the rear of the right iron separator 21. When the right iron separator 21 needs iron removal, the central controller 4 controls the right iron separator 21... After moving to the left and above collector 5, the power is cut off to automatically remove iron from iron separator 21. At this time, another iron separator 21 moves along the track to directly above coal flow 100 and is powered on to adsorb iron objects 200 in coal flow 100. The central controller 4 adjusts the positions of the two iron separators 21 to ensure that one iron separator 21 is always located above coal flow 100 to adsorb iron objects 200 in coal flow 100. This ensures that iron objects 200 in coal flow 100 can be adsorbed and iron can be automatically removed from iron separator 21 when coal flow 100 is uninterrupted, thereby improving the conveying efficiency of the conveyor.

[0036] In some embodiments, when the iron removal assembly begins to adsorb iron objects in the coal stream, the central controller compares the real-time size S1 of the iron object captured by the camera with a size reference value S0. S1 is the real-time size of the iron object captured by the camera, and the central controller contains the size reference value S0.

[0037] If S1≥S0, the central controller controls the current iron removal component to move away from the coal flow, and at the same time controls another iron removal component adjacent to the current iron removal component to move towards the coal flow and move to directly above the coal flow.

[0038] If S1 < S0, the central controller will not adjust the current working state of the iron removal component.

[0039] Specifically, such as Figure 3As shown, when one of the iron removal components is directly above the coal flow, it is energized to enable its adsorption function. Simultaneously, the central controller photographs the iron objects adsorbed by the component to obtain their real-time dimensions. This real-time dimension refers to the largest size among all iron objects adsorbed on the iron remover in the photograph. When the real-time dimension is greater than or equal to the reference size, it indicates the presence of large iron objects on the iron remover. Large iron objects can easily scratch the conveyor belt. In this case, the central controller controls the current iron removal component to move towards the collector. The directional movement automatically removes iron. The position of another iron removal component is adjusted so that it is directly above the coal flow to adsorb iron objects in the coal flow. When the real-time size of the iron object is smaller than the size reference value, it means that the iron objects on the iron remover are all small-sized iron objects. At this time, the working state and position of the current iron removal component are not adjusted, so that it continues to adsorb iron objects. In this embodiment, a camera is set to photograph the size of the iron objects, which avoids production accidents caused by long iron objects adsorbed on the iron remover easily scratching the conveyor belt, ensuring the normal operation of the conveyor, and thus ensuring the conveying efficiency of the conveyor.

[0040] In some embodiments, when the real-time size of the iron object captured by the camera is smaller than a size reference value, the angle between the iron remover detected by the leveling instrument and the horizontal line is set to A, and the angle reference value is set to A0 in the central controller. The controller compares the angle A between the iron remover detected by the leveling instrument and the horizontal line with the angle reference value A0.

[0041] If A≥A0, the central controller controls the current iron removal component to move away from the coal flow, and at the same time controls another iron removal component adjacent to the current iron removal component to move towards the coal flow and move to directly above the coal flow.

[0042] If A < A0, the central controller will not adjust the current working status of the iron removal component.

[0043] Specifically, when the real-time size of the iron object captured by the camera is smaller than the size reference value, it indicates that the size of the iron object is within the size reference range, and no adjustment to the current working state of the iron removal component is required. At this time, the central controller compares the tilt angle of the iron remover (i.e., the angle between the iron remover and the horizontal line) with the angle reference value to avoid the iron remover tilting too large, which would cause an uneven adsorption capacity of the iron remover for the iron in the coal flow, thus affecting the adsorption performance of the iron remover. That is, when the angle between the iron remover and the horizontal line is smaller than the angle reference value, it indicates that the tilt angle of the iron remover is within the allowable range, and no adjustment to the working state of the iron removal component is required. The system adjusts its state. When the angle between the iron separator and the horizontal line is greater than the reference angle value, it indicates that the tilt angle of the iron separator is not within the allowable range. In order to ensure the adsorption performance of the iron separator, the central controller controls the current iron removal component to move towards the collector. When it is directly above the collector, the iron removal component is powered off and automatically removes iron. The position of another iron removal component is adjusted so that it is directly above the coal flow to adsorb the iron in the coal flow. In this embodiment, a level detector is set to monitor the tilt angle of the iron separator, which avoids the iron separator from tilting too much, affecting the adsorption performance of the iron separator, and ensuring the normal operation of the conveyor.

[0044] For example, the angle reference value A0 can be 50°, 60°, or 70°.

[0045] In some embodiments, when the angle between the iron remover and the horizontal line detected by the level detector is less than the angle reference value, the central controller compares the current working time of the iron removal assembly with the time reference value, sets the current working time of the iron removal assembly as T, and sets the time reference value to T0 within the central controller 4.

[0046] If T≥T0, the central controller controls the current iron removal component to move away from the coal flow, and at the same time controls another iron removal component adjacent to the current iron removal component to move towards the coal flow and move to directly above the coal flow.

[0047] If T < T0, the central controller will not adjust the current working state of the iron removal component. The central controller compares the real-time size of the iron object captured by the camera with the size reference value.

[0048] Specifically, when the tilt angle of the iron separator is within the reference angle range, there is no need to adjust the working state of the current iron removal component. The central controller monitors the adsorption time of the current iron removal component. If the working time of the current iron removal component is greater than or equal to the time reference value, it indicates that the working time of the current iron removal component is long enough. To ensure good adsorption performance of the iron removal component, automatic iron removal is required. The central controller controls the current iron removal component to move towards the collector. When it is directly above the collector, the power is cut off to automatically remove iron. The position of another iron removal component is adjusted so that it is directly above the coal flow. The system adsorbs iron from the coal flow. If the current working time of the iron removal component is less than the time reference value, it means that the current working time of the iron removal component is still within the time reference value range, and there is no need to adjust the working status of the current iron removal component. At this time, the central controller compares the real-time size of the iron captured by the camera with the size reference value, forming a cycle until the current iron removal component needs to automatically remove iron. The central controller then monitors the working status of the new iron removal component above the coal flow to ensure the adsorption performance of the iron removal component and realize automatic iron removal of the iron removal component while the coal flow is uninterrupted, thus ensuring the conveying efficiency of the conveyor.

[0049] Understandably, when coal is hoisted using a vertical shaft method with double skips and a single stroke, the loading and unloading time is approximately 2 minutes. This means there will be time intervals in the coal flow of the conveyor. The working time of the iron separator can be combined with the time interval of the coal flow. If the working time of the iron separator is greater than or equal to the time reference value, but the time interval between the iron separator and the coal flow is within 30 seconds or 1 minute, the working time of the current iron separator component can be extended. This allows the working time of the iron separator to be combined with the time interval of the coal flow, adapting to the actual working conditions on site and thus improving the conveyor's efficiency.

[0050] In some embodiments, the iron separator 21 is provided with a connecting ear 211 at the end away from the coal flow 100. The number of connecting ears 211 is set to multiple. The multiple connecting ears 211 are arranged at intervals in the length direction of the iron separator 21. The connecting ears 211 are connected to the connecting component 22.

[0051] Specifically, such as Figure 1 As shown, the iron remover 21 is provided with a connecting ear 211 on its upper part. There are three connecting ears 211, which are arranged at intervals in the left and right directions. The connecting ears 211 are connected to the connecting component 22 to realize the connection between the iron remover 21 and the support component 1.

[0052] In some embodiments, the connecting component 22 includes a pulley assembly 221 and a circular chain 222. The pulley assembly 221 cooperates with the slide rail 111. One end of the circular chain 222 is connected to one of two adjacent connecting ears 211, and the other end of the circular chain 222 passes through the pulley assembly 221 and is connected to the other connecting ear 211.

[0053] Specifically, the upper end of the pulley block 221 engages with the slide rail 111, and the lower end of the pulley block 221 is connected to the circular chain 222. Through the engagement of the pulley block 221 with the slide rail 111 and the connection of the circular chain 222 to the connecting lug 211 and the pulley block 221 respectively, the iron separator 21 can move relative to the slide rail 111 along its extension direction, thereby facilitating the movement of the iron separator 21 from the coal flow 100 direction towards the collector 5. It can be understood that in this embodiment, the first support member 11 is a ring-shaped support member, and multiple iron removal components 2 move in the same direction along the extension direction of the slide rail 111.

[0054] In some embodiments, there are multiple connecting parts 22, which are arranged at intervals in the extending direction of the slide rail 111.

[0055] Specifically, since the stability of a single pulley assembly 221 is poor, and the single pulley assembly 221 also needs to bear the weight of the iron remover 21 and the iron objects 200 adsorbed by the iron remover 21, the bearing capacity of a single pulley assembly 221 is limited. In this embodiment, the number of connecting components 22 is set to two. The two connecting components 22 are arranged at intervals in the extension direction of the slide rail 111, that is, each iron remover 21 is connected to two connecting components 22. Each connecting component 22 includes a pulley assembly 221 and a circular chain 222. Each pulley assembly 221 includes two pulleys. The connection stability between the iron remover 21 and the support assembly 1 is ensured by setting multiple connecting components 22.

[0056] In some embodiments, the support assembly 1 further includes a second support member 12, one end of which is adapted to be connected to the ground, and the other end of which is connected to the first support member 11 to fix the position of the first support member 11.

[0057] Specifically, the second support member 12 extends in the vertical direction, and the upper end of the second support member 12 is connected to the first support member 11 to support and fix the first support member 11. The number of second support members 12 is set to two, and the two second support members 12 are arranged at intervals in the left and right direction. The arrangement of the two second support members 12 ensures that the first support member 11 is fixed above the conveyor and collector 5.

[0058] In some embodiments, the iron removal device further includes a collector 5 located below the annular support and spaced apart from the coal flow 100.

[0059] Specifically, collector 5 is located on the left side of the conveyor and below the annular support. When the iron removal assembly 2 moves above collector 5, the iron objects 200 adsorbed on the iron remover 21 are automatically dropped into collector 5 by cutting off the power to the iron removal assembly 2.

[0060] In some embodiments, when the central controller 4 controls the current iron removal component 2 to move away from the coal flow 100, the central controller 4 controls the current iron removal component 2 to move above the collector 5 and then cuts off the power to the current iron removal component 2.

[0061] Specifically, when the iron remover 21 is working, if the size of the iron object 200 adsorbed on the iron remover 21 is greater than or equal to the size reference value, the tilt angle of the iron remover 21 is greater than or equal to the angle reference value, or the working time of the iron remover 21 reaches the preset requirement, the central controller 4 controls the current iron remover 21 to move to the left and above the iron remover 21, and cuts off the power to the iron remover 21, so that the iron object 200 adsorbed on the iron remover 21 falls into the iron removal area by spontaneous combustion, thus completing the automatic iron removal of the iron remover 21, reducing the downtime of the conveyor, and this embodiment avoids manual iron removal, realizes the automatic iron removal of the iron remover 21, reduces the operation danger, and improves the conveying efficiency of the conveyor.

If A < A0, the central controller will not adjust the current working state of the iron removal component; When the angle between the iron remover and the horizontal line detected by the leveling instrument is less than the angle reference value, the central controller compares the current working time T of the iron removal component with the time reference value T0, sets the current working time of the iron removal component to T, and sets the time reference value to T0 within the central controller. If T≥T0, the central controller controls the current iron removal component to move away from the coal flow, and at the same time controls another iron removal component adjacent to the current iron removal component to move towards the coal flow and move to directly above the coal flow. If T < T0, the central controller will not adjust the current working state of the iron removal component, and the central controller will compare the real-time size of the iron object captured by the camera with the size reference value.
