Description

Technical Field

[0001] This invention relates to the field of coal mine production technology, and in particular to an iron remover and an iron removal method. Background Technology

[0002] During raw coal mining, the upper and lower roadways of the working face are supported by anchor mesh beams. During the mining process, iron materials from the support are cut into the coal flow by the coal mining machine. Due to the rapid mining speed, the raw coal contains a large amount of iron impurities. These iron objects mixed in with the coal blocks can cause them to scrape against or even jam the conveyor belt during transport, posing a safety hazard and easily leading to accidents. Electromagnetic separators utilize the principle of electromagnetism. Current passing through an electromagnetic coil generates a very strong magnetic field. When material passes through, ferromagnetic impurities are attracted, achieving the purpose of iron removal.

[0003] Most existing electromagnetic separators are installed above conveyor belts. They use the magnetic force of the separator to attract iron mixed with coal lumps, thereby removing iron from the coal flow.

[0004] The iron separator is fixed to the conveyor belt. Manually recovering the iron adsorbed on the electromagnetic iron separator requires stopping the conveyor belt. Iron removal work restricts and affects production operations, reducing the raw coal production time. Taking the No. 1 mining area of ​​Lingdong Coal Mine as an example, the machine is stopped twice per shift for iron removal, each time for 20 minutes, resulting in a daily reduction of about 1,000 tons of raw coal production. Iron removal and iron picking are labor-intensive, and in order to collect iron slag as quickly as possible and restore the production line, workers are prone to accidents such as bumps and collisions in the chaos, which affects production efficiency. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an iron remover and an iron removal method, which solves the technical problem that the iron remover is fixed above the belt, and the iron removal requires the belt conveyor to be stopped, which affects production efficiency and is not suitable for high-intensity production.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0009] In a first aspect, embodiments of the present invention provide an iron separator, comprising an iron separator support arranged along the length direction perpendicular to a belt conveyor, an iron separator body disposed on the iron separator support, and a receiving device. The iron separator body is located on the upper side of the belt conveyor, and the adsorption end of the iron separator body is close to the transport end face of the belt conveyor. Two sets of receiving devices are disposed and located on both sides of the belt conveyor respectively. A switching component is disposed on the iron separator support, and two sets of iron separator bodies are disposed. The switching component drives the two sets of iron separator bodies to switch positions on the upper side of the belt conveyor and on the upper side of the two sets of receiving devices to maintain a continuous presence of one set of iron separator bodies on the upper side of the belt conveyor for adsorption work.

[0010] This invention discloses an iron separator. When iron is removed using this separator, the process involves the following steps: First, the iron separator bracket is vertically fixed to a belt conveyor, with the separator body positioned on top of the conveyor and two sets of receiving devices located on opposite sides of the conveyor. Second, as the conveyor transports coal, the separator body adsorbs and removes iron from the coal during transport. Third, once sufficient iron has been adsorbed at the lower end of the separator body in use, the transfer component moves the separator body towards one of the receiving devices, while the other separator body moves to the top of the conveyor. Fourth, the iron at the lower end of the separator body is removed to the receiving device. Fifth, step three is repeated, moving the other separator body to the other receiving device and repeating step four. This iron separator allows for continuous iron removal during iron recovery, thereby improving efficiency.

[0011] Optionally, the transposition assembly includes a transposition shaft vertically rotatably connected to the iron removal bracket and two transposition brackets horizontally connected to the side end of the transposition shaft. The two transposition brackets are arranged vertically, and the two iron removal bodies are respectively fixed to the ends of the two transposition brackets away from the transposition shaft.

[0012] By setting a transposition shaft and two transposition brackets perpendicular to the transposition shaft and perpendicular to each other, when the iron separator body installed on one transposition bracket is located on the upper side of the belt conveyor, one iron separator body is located on the upper side of a receiving device. When transposition is required, the transposition shaft can be rotated 90 degrees for quick replacement. This scheme makes the transposition of the iron separator body more convenient and faster.

[0013] Optionally, the transposition bracket extends along its own length direction to the other side of the transposition shaft and is fixed to the iron remover body, and the two transposition brackets are of the same length and are respectively divided by the transposition shaft.

[0014] By extending the transposition brackets, the two transposition brackets form a cross structure with the transposition shaft as the axis, and the iron separator body is fixed at both ends of the two transposition brackets. On the one hand, the mass distribution is more balanced, ensuring the stability of the transposition component. On the other hand, each transposition has two iron separator bodies located at the front and rear ends of the belt conveyor to remove iron, thereby improving the iron removal effect.

[0015] Optionally, the transposition assembly includes a transposition slide rail horizontally disposed on the iron removal bracket and a transposition carriage horizontally reciprocatingly connected to the lower end of the transposition slide rail, with the two iron removal bodies respectively fixed to the two ends of the transposition carriage in the sliding direction.

[0016] By setting a transposition slide rail on the iron removal bracket, the transposition slide can slide back and forth along the transposition slide rail, fixing the two iron removal bodies to the two ends of the transposition slide respectively, thereby quickly transposing the iron removal body located on the belt conveyor, while ensuring that the transposed iron removal body moves to the upper side of a receiving device. This scheme makes the transposition of the iron removal body more convenient and faster.

[0017] Optionally, the shifting assembly has a tilt angle adjustment component at the ends of the two iron separator bodies, which drives the iron separator bodies to tilt toward the conveying direction of the belt conveyor and adjusts the tilt angle.

[0018] By setting up a tilt angle adjustment component, the tilt angle of the iron separator body towards the belt conveyor can be adjusted through this component. In this way, the tilt angle of the iron separator body can be adjusted according to the different iron content in the coal flow, thereby improving the iron removal efficiency.

[0019] Optionally, the tilt angle adjustment assembly includes an adjustment base at the top and an adjustment base rotatably disposed at the lower end of the adjustment base and fixed to the top of the iron separator body. The rotation axis of the adjustment base is arranged horizontally. An arc-shaped positioning rod with its own rotation axis as the axis is provided on the upper end surface of the adjustment base away from its own rotation axis. The adjustment base has a positioning hole that is coaxial with the rotation axis of the adjustment base and is connected vertically to the upper end, allowing the arc-shaped positioning rod to be inserted. A positioning nut is threaded onto the arc-shaped positioning rod, and the positioning nut abuts against the upper end surface of the adjustment base.

[0020] By fixing the adjusting base to the upper displacement assembly, the adjusting base is fixed to the upper end of the iron separator body, so that the adjusting base and the adjusting base are rotatably connected together, and the rotating shaft is horizontal. The arc-shaped positioning rod on the adjusting base is inserted into the positioning hole as the adjusting base rotates, and then the positioning nut is fixed to the top of the arc-shaped positioning rod by thread, so that the positioning nut abuts against the upper end face of the adjusting base, thereby positioning the included angle between the adjusting base and the adjusting base. When it is necessary to adjust the tilt angle of the lower iron separator body, it is only necessary to tighten the positioning nut, which is more convenient.

[0021] Optionally, the iron removal support includes vertical frames supported on both sides of the belt conveyor and horizontal frames connected to the top of the two sets of vertical frames. The horizontal frames are vertically provided with adjusting pins at both ends. The top of the vertical frames is provided with adjusting holes for vertical insertion of the adjusting pins. A support spring is vertically inserted into the adjusting holes of the vertical frames and abuts against the lower end of the adjusting pins. The side end of the vertical frames is horizontally threaded with adjusting bolts that pass through the adjusting holes and abut against the side end of the adjusting pins.

[0022] By inserting the adjusting pin into the adjusting hole and abutting against the upper end of the support spring, the support spring supports most of the weight of the cross frame, the shifting component, and the iron separator body. Then, the adjusting bolt is inserted into the adjusting hole and pressed against the side end of the adjusting pin to position the cross frame. When it is necessary to adjust the height of the iron separator body, simply loosen the adjusting bolts on both sides and then adjust the height of the cross frame, which is very convenient.

[0023] Optionally, the receiving device includes a receiving bucket horizontally suspended and fixed to one end of the vertical frame near the belt conveyor, a receiving platform horizontally fixed to the side of the vertical frame and abutting the ground and located below the receiving bucket, and a receiving car that moves along the ground to the receiving platform to receive the iron leaking from the receiving bucket. The receiving bucket is in the shape of a funnel with its opening facing upward.

[0024] By assembling a receiving device consisting of a receiving hopper, a receiving platform, and a receiving vehicle, the receiving vehicle is moved to the top of the receiving platform during use, aligning with the bottom of the receiving hopper. The receiving hopper is funnel-shaped with its flared end facing upwards, allowing iron objects falling from the iron remover body to be better collected and fall into the receiving vehicle. Once enough iron objects have been collected in the receiving vehicle, it can be moved and replaced, thus achieving continuous iron removal.

[0025] Optionally, the two sets of vertical frames are vertically provided with a drive cylinder on one end face that is close to each other, which drives the receiving platform to move the receiving vehicle vertically.

[0026] By vertically installing a drive cylinder on the side of the frame, the drive cylinder can move the receiving platform and the receiving vehicle vertically together. This allows the receiving bucket to be positioned higher, reducing the chance of iron objects falling outside the receiving bucket during the process. At the same time, it allows the receiving vehicle to be positioned higher, thus better receiving the iron objects that leak from the receiving bucket.

[0027] Secondly, embodiments of the present invention provide an iron removal method, comprising: Step 1, vertically fixing the iron removal bracket to a belt conveyor, such that the iron remover body is located on the upper side of the belt conveyor, and two sets of receiving devices are respectively located on both sides of the belt conveyor; Step 2, as the belt conveyor transports coal, the iron remover body adsorbs and removes iron from the coal during the transport process; Step 3, when the lower end of the iron remover body in use has adsorbed enough iron, the iron remover body is moved to the upper side of one of the receiving devices by the switching component, at which time the other iron remover body moves to the upper side of the belt conveyor; Step 4, removing the iron from the lower end of the iron remover body to the receiving device; Step 5, repeating Step 3, so that the other iron remover body moves to the upper side of the other receiving device and repeating Step 4.

[0028] This iron removal method can effectively avoid wasting time in the process of recycling ironware, thereby improving iron removal efficiency.

[0029] (III) Beneficial Effects

[0030] The beneficial effects of this invention are as follows: When the iron separator and iron removal method of this invention are used for iron removal, the process involves the following steps: First, the iron removal bracket is vertically fixed to the belt conveyor, so that the iron separator body is located on the upper side of the belt conveyor, and the two sets of receiving devices are located on opposite sides of the belt conveyor. Second, as the belt conveyor transports the coal, the iron separator body adsorbs and removes iron from the coal during transport. Third, when the lower end of the iron separator body in use has adsorbed sufficient iron, the transfer component moves the iron separator body to the upper side of one of the receiving devices, at which time the other iron separator body moves to the upper side of the belt conveyor. Fourth, the iron at the lower end of the iron separator body is removed to the receiving device. Fifth, step three is repeated, so that the other iron separator body moves to the upper side of the other receiving device and step four is repeated. This iron separator allows for continuous iron removal during the iron recovery process, thereby improving efficiency. Attached Figure Description

[0039] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0040] Example 1

[0041] Reference Figures 1-3 A magnetic separator includes a magnetic separator support 1 arranged along the length of a vertical belt conveyor, a transposition component 2 arranged on the magnetic separator support 1, a tilt angle adjustment component 3, a magnetic separator body 4, and a receiving device 5.

[0042] The iron removal support 1 includes vertical frames 11 that are vertically supported on both sides of the belt conveyor and horizontal frames 12 that are horizontally connected to the top of the two sets of vertical frames 11. The horizontal frames 12 are vertically provided with adjusting pins 121 at both ends. The top of the vertical frames 11 is provided with adjusting holes 111 for vertical insertion of the adjusting pins 121. A support spring 13 that abuts against the lower end of the adjusting pin 121 is vertically inserted into the adjusting holes 111 of the vertical frames 11. An adjusting bolt 14 that passes through the adjusting holes 111 and abuts against the side end of the adjusting pin 121 is horizontally threaded to the side end of the vertical frames 11. The support spring 13 supports most of the weight of the cross frame 12, the tilt angle adjustment component 3, the shifting component 2, and the iron remover body 4. The adjustment bolt 14 is inserted into the adjustment hole 111 and pressed against the side of the adjustment post 121 to position the cross frame 12. When it is necessary to adjust the height of the iron remover body 4, simply loosen the adjustment bolts 14 on both sides and then adjust the height of the cross frame 12, which is very convenient.

[0043] The iron separator body 4 is located on the upper side of the belt conveyor. The adsorption end of the iron separator body 4 is close to the transport end face of the belt conveyor. Two sets of receiving devices 5 are provided and located on both sides of the belt conveyor respectively. Two sets of iron separator bodies 4 are provided. The switching component 2 drives the two sets of iron separator bodies 4 to switch positions on the upper side of the belt conveyor and on the upper side of the two sets of receiving devices 5 so as to keep a set of iron separator bodies 4 continuously performing adsorption work on the upper side of the belt conveyor.

[0044] The transposition assembly 2 includes a transposition slide rail 21 horizontally fixed to the lower end of the crossbeam 12 by bolts, and a transposition carriage 22 connected to the lower end of the transposition slide rail 21 by a cylinder-controlled horizontal reciprocating sliding motion. The length direction of the transposition slide rail 21 is the same as the length direction of the crossbeam 12. Two iron separator bodies 4 are respectively fixed to the two ends of the transposition carriage 22 in the sliding direction. The transposition carriage 22 slides reciprocally along the transposition slide rail 21, fixing the two iron separator bodies 4 to the two ends of the transposition carriage 22, thereby quickly transposing the iron separator bodies 4 located on the belt conveyor, while ensuring that the transposed iron separator bodies 4 move to the upper side of a receiving device 5.

[0045] The tilt angle adjustment assembly 3 includes a top adjustment base 31 and an adjustment base 32, which is rotatably mounted on the lower end of the adjustment base 31 and fixed to the top of the iron separator body 4. The adjustment base 31 is fixed to the lower end of the shift slide 22 by bolts. The rotation axis of the adjustment base 32 is horizontally arranged. An arc-shaped positioning rod 33 with its own rotation axis as the axis is integrally provided on the upper end surface of the adjustment base 32 on the side away from its own rotation axis. The adjustment base 31 has a positioning hole 311 that is coaxial with the rotation axis of the adjustment base 32 and allows the arc-shaped positioning rod 33 to be inserted. A positioning nut 34 is threaded onto the arc-shaped positioning rod 33 and abuts against the upper end surface of the adjustment base 31. The positioning nut 34 abuts against the upper end surface of the adjustment base 31, thereby positioning the included angle between the adjustment base 32 and the adjustment base 31. When it is necessary to adjust the tilt angle of the lower iron separator body 4, it is only necessary to tighten the positioning nut 34.

[0046] The receiving device 5 includes a receiving bucket 51 horizontally suspended and welded to one end of the vertical frame 11 near the belt conveyor; a receiving platform 52 horizontally welded to the side of the vertical frame 11 and abutting the ground, located below the receiving bucket 51; and a receiving cart 53 that moves along the ground to the receiving platform 52 to receive iron objects falling from the receiving bucket 51. The receiving bucket 51 is funnel-shaped with its flared end facing upwards. In use, the receiving cart 53 moves to the upper end of the receiving platform 52, aligning the receiving cart 53 with the lower end of the receiving bucket 51, setting the receiving bucket 51 in a funnel shape with its flared end facing upwards. This allows iron objects falling from the iron remover body 4 to be better collected and fall into the receiving cart 53. When enough iron objects have been collected in the receiving cart 53, the receiving cart 53 can be moved and replaced.

[0047] When using the above-mentioned iron separator for iron removal, the steps are as follows: Step 1: The iron separator bracket 1 is vertically fixed to the belt conveyor, so that the iron separator body 4 is located on the upper side of the belt conveyor, and the two sets of receiving devices 5 are located on both sides of the belt conveyor; Step 2: As the belt conveyor transports the coal, the iron separator body 4 adsorbs and removes iron from the coal during the transportation process; Step 3: When the lower end of the iron separator body 4 in use has adsorbed enough iron, the iron separator body 4 is moved to the upper side of the receiving device 5 on one side by the switching component 2, and at this time, the other iron separator body 4 moves to the upper side of the belt conveyor; Step 4: The iron at the lower end of the iron separator body 4 is removed to the receiving device 5; Step 5: Step 3 is repeated, so that the other iron separator body 4 moves to the upper side of the other receiving device 5 and Step 4 is repeated.

[0048] Example 2

[0049] The difference between this embodiment and Embodiment 1 is that...

[0050] Reference Figure 4The transposition assembly 2 includes a transposition shaft 23 vertically rotatably connected to the lower middle of the crossbeam 12 and driven by a motor, and two transposition brackets 24 horizontally welded to the side of the transposition shaft 23. The two transposition brackets 24 are arranged vertically, and two iron separator bodies 4 are respectively fixed to the ends of the two transposition brackets 24 away from the transposition shaft 23. The transposition brackets 24 extend along their own length towards the other side of the transposition shaft 23 and are fixed with iron separator bodies 4. The adjusting base 31 is fixed to the end of the transposition bracket 24 by bolts. The two transposition brackets 24 are of the same length and are evenly divided by the transposition shaft 23. The two transposition brackets 24 form a cross structure with the transposition shaft 23 as the axis, and iron separator bodies 4 are fixed to both ends of the two transposition brackets 24. On the one hand, this makes the mass distribution more balanced and ensures the stability of the transposition assembly 2. On the other hand, it ensures that there are two iron separator bodies 4 at the front and rear ends of the belt conveyor for iron removal during each transposition, thereby improving the iron removal effect.
