Description

Technical Field

[0001] The present invention relates to the technical field of magnetic separation equipment, and specifically relates to a vertical magnetic separator for removing iron from pulverized coal in coal slime processing. Background Art

[0002] A magnetic separator is a screening device used to remove iron powder and the like from recycled powdery and granular materials. Magnetic separators are widely used in resource recovery, as well as in other factories such as the wood industry, mining industry, ceramics industry, chemical industry, and food industry, and are suitable for granular and powdery materials. It is also used for the iron removal operation of materials such as coal, non-metallic minerals, and building materials, and is one of the most widely used and highly versatile machine types in the industry. In coal slime processing, iron impurities will be contained in the pulverized coal, and it is necessary to remove the iron impurities. Therefore, a magnetic separator for removing iron from pulverized coal is required. The magnetic separator for removing iron from pulverized coal can effectively remove iron impurities in the pulverized coal, reduce the iron content in the pulverized coal to a relatively low level, improve the quality and purity of the pulverized coal, and meet the requirements of different industrial productions for the quality of pulverized coal.

[0003] Currently, the existing magnetic separators for removing iron from pulverized coal are inconvenient for preprocessing the pulverized coal, resulting in the pulverized coal sticking together to form coal powder clusters, making it inconvenient for subsequent iron removal from the pulverized coal, and the pulverized coal is prone to accumulation, resulting in insufficient iron removal and affecting the subsequent use of the pulverized coal. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] A vertical magnetic separator for removing iron from pulverized coal in coal slime processing, comprising:

[0006] A machine shell, in the middle of the top of the machine shell, a feed hopper is fixedly installed, and a rectangular opening is provided at the side of the surface of the machine shell;

[0007] An iron removal mechanism, which is used for magnetic separation and iron removal of pulverized coal, and the iron removal mechanism is installed in the middle of the inner part of the machine shell;

[0008] Among them, the iron removal mechanism includes a bracket and a scraping component. The two ends of the surface of the bracket are fixedly installed with the inner wall of the machine shell. The scraping component is installed on the inner wall of the machine shell, and the position of the scraping component corresponds to the position of the bracket. A first driver, a second driver, and a third driver are sequentially installed at the top of the bracket. The output end of the first driver is installed with a first magnetic disk, the output end of the second driver is installed with a second magnetic disk, and the output end of the third driver is installed with a third magnetic disk. A pressing block is fixedly connected to the edge of the bottom of the second magnetic disk. By allowing the pulverized coal to fall onto the first magnetic disk, the second magnetic disk, and the third magnetic disk, the iron substances can be magnetically attracted, and since the first magnetic disk, the second magnetic disk, and the third magnetic disk are inclinedly installed, the pulverized coal falling onto the first magnetic disk, the second magnetic disk, and the third magnetic disk can fall off, so that the pulverized coal and the iron substances can be separated;

[0009] A material guiding mechanism for preprocessing pulverized coal. The material guiding mechanism is installed inside the casing and directly below the feed hopper.

[0010] Among them, the material guiding mechanism includes a diversion plate and a material spreading component. The diversion plate is fixedly installed on the inner wall of the casing. The material spreading component is installed at the top of the inner cavity of the casing. A hydraulic rod is installed at the bottom of the diversion plate. The telescopic end of the hydraulic rod is fixedly connected to a cross beam. A connecting rod is hinged on the outer cylindrical surface of the cross beam. An elastic wire is fixedly connected to the outer cylindrical surface of the connecting rod. A pushing plate is fixedly connected to the middle of the top of the cross beam. As the reciprocating material spreading plate and the material distributing piece spread the pulverized coal raw material, the pulverized coal raw material falls onto the elastic wire and is evenly distributed on the connecting rod by the elastic wire to form a wire mesh shape, so as to break the pulverized coal mass formed by adhesion. The pulverized coal passes through the elastic wire and falls onto the diversion plate, and then through the diversion of the diversion plate, the pulverized coal is conveyed to the first magnetic disk, the second magnetic disk and the third magnetic disk for subsequent magnetic separation and iron removal.

[0011] Preferably, the first driver, the second driver and the third driver are evenly installed on the top of the bracket. The first magnetic disk, the second magnetic disk and the third magnetic disk are all installed obliquely.

[0012] Preferably, there are four pressing blocks, and the four pressing blocks are evenly installed at the edge of the bottom of the second magnetic disk.

[0013] Preferably, the scraping component includes a V-shaped plate. The bent part at the bottom of the V-shaped plate is fixedly installed on the surface of the casing, and the V-shaped plate and the bracket are installed at the same height. The top end of the V-shaped plate penetrates the surface of the casing and extends into its interior. A right-angle support rod is fixedly connected to the inner side surface of the V-shaped plate. The right-angle support rod is installed inside the casing. A scraping plate is fixedly connected to the top end of the right-angle support rod. The position of the scraping plate corresponds to the positions of the first magnetic disk, the second magnetic disk and the third magnetic disk. By making the bottom of the scraping plate fit the top of the magnetic disk, and scraping plates are installed on the tops of the three magnetic disks of the first magnetic disk, the second magnetic disk and the third magnetic disk, the iron substances magnetically adsorbed on the tops of the first magnetic disk, the second magnetic disk and the third magnetic disk can be scraped off. Under the guiding action of the scraping plate, the iron substances fall into the interior of the V-shaped plate, and due to the inclined installation of the V-shaped plate, the iron substances are discharged from the interior of the casing.

[0014] Preferably, there are three V-shaped plates, and the three V-shaped plates are evenly installed on the surface of the casing. The V-shaped plates are installed obliquely.

[0015] Preferably, the bottom end of the deflector extends above the first disk, above the second disk, and above the third disk. The connecting rod and the elastic wire are installed directly above the deflector. The top end of the connecting rod fits against the inclined surface of the inner wall of the casing. By extending the telescopic end of the hydraulic rod, the crossbeam is pushed upward, so that the connecting rod moves upward. By using the fact that the top end of the connecting rod fits against the inclined surface of the inner wall of the casing, as the connecting rod continues to rise, the connecting rod can drive the elastic wire to rotate and adjust the angle. Along with the contraction of the telescopic end of the hydraulic rod, the crossbeam drives the connecting rod to move downward. Under the action of the self-gravity of the connecting rod, the connecting rod drives the elastic wire to rotate in the reverse direction for resetting. The connecting rod can drive the elastic wire to swing back and forth, so that the moving elastic wire is always in a dynamic state, which is convenient for processing the pulverized coal mass.

[0016] Preferably, the material spreading assembly includes a square support rod, which is fixedly installed on the inner wall of the casing through a base frame. A slider is slidably installed at the middle of the surface of the square support rod. One end of the slider away from the square support rod is fixedly connected to a material spreading plate. The material spreading plate is installed directly below the feed hopper. An elastic reset strip is fixedly connected between the surface of the slider and the base frame at the end of the square support rod. A material dividing piece is fixedly connected to the bent part of the surface of the material spreading plate. A linear hole is formed in the surface of the material spreading plate, and the linear hole is formed at the position of the bottom end of the material dividing piece. A ball head rod is fixedly connected to the middle of the bottom of the material spreading plate. By extending the telescopic end of the hydraulic rod, the crossbeam can be pushed upward, so that the top plate is pushed upward together with the crossbeam. The upward pushing force can be applied to the ball head rod through the top plate. Considering the fixed connection between the slider and the material spreading plate and under the guiding action of the square support rod, the slider and the material spreading plate move horizontally as a whole, and the elastic reset strip is compressed. By contracting the telescopic end of the hydraulic rod, the crossbeam and the top plate move downward together. The upward pushing force of the top plate on the ball head rod disappears. Under the elastic force of the elastic reset strip, the slider and the material spreading plate move in the reverse direction for resetting. The material spreading plate drives the material dividing piece to move together, so that the pulverized coal raw material falling from the feed hopper is affected by the linear reciprocating movement of the material spreading plate and the material dividing piece, and the pulverized coal raw material can be sprinkled, so that the pulverized coal raw material is evenly fed, and the situation of pulverized coal raw material accumulation is not likely to occur.

[0017] Preferably, the elastic reset strip is arc-shaped. The material dividing pieces are evenly distributed at the bent part of the surface of the material spreading plate. The ball head rod is installed obliquely.

[0018] Preferably, a discharging mechanism is installed at the bottom of the inner cavity of the casing. The discharging mechanism includes a discharging plate. A baffle is fixedly connected to the side of the top of the discharging plate. An inclined strip-shaped hole is formed in the middle of the surface of the baffle. A sliding beam is slidably installed on the surface of the baffle through the inclined strip-shaped hole. A pressure-receiving rod is fixedly installed in the middle of the top of the sliding beam. The pressure-receiving rod is installed directly below the pressing block. A connecting seat is fixedly installed on the surface of the sliding beam, and the position of the connecting seat corresponds to the position of the pressure-receiving rod. A pushing piece is fixedly installed at the bottom end of the connecting seat. An elastic ring is fixedly connected between the top of the connecting seat and the outer cylindrical surface of the pressure-receiving rod. As the pulverized coal slides off the first magnetic disk, the second magnetic disk and the third magnetic disk, the pulverized coal falls onto the discharging plate, causing the pulverized coal to accumulate. By installing the discharging plate obliquely, the pulverized coal slides downward along the discharging plate until it is discharged from the inside of the casing. Moreover, two symmetrical baffles are used to block the pulverized coal falling on the top of the discharging plate, making it difficult for the pulverized coal to scatter, further facilitating the discharging of the pulverized coal.

[0019] Preferably, there are two baffles, and the two baffles are symmetrically installed along the central axis of the middle of the discharging plate. The sliding beam is installed directly above the discharging plate. As the second magnetic disk rotates, the pressing block can be driven to rotate in a circle. Through the contact between the arc surface on the outside of the pressing block and the top end of the pressure-receiving rod, the pressure-receiving rod receives a downward pressing force from the pressing block. The pressure-receiving rod applies the pressure to the sliding beam, and through the guiding of the inclined strip-shaped hole, the sliding beam drives the pressure-receiving rod and the connecting seat to move obliquely downward, and the elastic piece is compressed. As the connecting seat moves obliquely downward, the bottom of the pushing piece contacts the top of the discharging plate, and by continuously moving the pushing piece downward, the pulverized coal on the top of the discharging plate can be pushed downward, and it is not easy for the pulverized coal to accumulate.

[0020] As the pressing block separates from the top of the pressure-receiving rod, the pressing force received by the pressure-receiving rod disappears. Under the elastic force of the elastic piece, the sliding beam drives the pressure-receiving rod and the connecting seat to move obliquely upward for resetting, so that the pushing piece is lifted, facilitating the continuous downward movement of the pulverized coal falling on the top of the discharging plate, and it is not easy for the pulverized coal to be pulled back.

[0021] The present invention provides a vertical magnetic separator for removing iron from pulverized coal in coal slime processing. It has the following beneficial effects:

[0022] First, in this vertical magnetic separator for removing iron from pulverized coal in coal slime processing, by presenting an overlapping state among the first magnetic disk, the second magnetic disk and the third magnetic disk, when the pulverized coal falls onto the first magnetic disk, the second magnetic disk and the third magnetic disk, the iron substances can be magnetically attracted. Moreover, since the first magnetic disk, the second magnetic disk and the third magnetic disk are installed obliquely, the pulverized coal falling onto the first magnetic disk, the second magnetic disk and the third magnetic disk can fall off, so that the pulverized coal and the iron substances can be separated, realizing the magnetic separation of the iron substances.

[0023] Second, for the vertical magnetic separator used for iron removal of pulverized coal processed from slime, by making the bottom of the scraping plate fit with the top of the magnetic disk, and scraping plates are installed on the tops of the first magnetic disk, the second magnetic disk and the third magnetic disk, the iron substances magnetically adsorbed on the tops of the first magnetic disk, the second magnetic disk and the third magnetic disk can be scraped off. Under the guiding action of the scraping plate, the iron substances fall into the interior of the V-shaped plate. With the V-shaped plate installed obliquely, the iron substances are discharged from the interior of the machine housing.

[0024] Third, for the vertical magnetic separator used for iron removal of pulverized coal processed from slime, the top plate pushes the ball head rod upward. Under the guiding action of the square support rod, the slider and the material spreading plate move horizontally as a whole. When the upward pushing force of the top plate on the ball head rod disappears, under the elastic force of the elastic reset strip, the slider and the material spreading plate move in the reverse direction to reset together. And the material spreading plate drives the dividing pieces to move together, so that the pulverized coal raw material falling from the feed hopper is affected by the linear reciprocating movement of the material spreading plate and the dividing pieces, and the pulverized coal raw material can be sprinkled, so that the pulverized coal raw material is evenly fed, and it is not easy to have the situation of accumulation of pulverized coal raw material.

[0025] Fourth, for the vertical magnetic separator used for iron removal of pulverized coal processed from slime, as the reciprocating moving material spreading plate and dividing pieces sprinkle the pulverized coal raw material, the pulverized coal raw material falls onto the elastic wires. And with the elastic wires evenly distributed on the connecting rod to form a wire mesh, the pulverized coal clusters formed by adhering together can be broken. And the pulverized coal passes through the elastic wires and falls onto the guide plate. Then, through the guiding of the guide plate, the pulverized coal is conveyed to the first magnetic disk, the second magnetic disk and the third magnetic disk, which is convenient for subsequent magnetic separation and iron removal.

[0026] Fifth, for the vertical magnetic separator used for iron removal of pulverized coal processed from slime, by the elongation of the telescopic end of the hydraulic rod, the cross beam is pushed upward to move, so that the connecting rod moves upward. And with the top end of the connecting rod fitting with the inclined surface of the inner wall of the machine housing, as the connecting rod continues to rise, the connecting rod drives the elastic wires to rotate and adjust the angle. Along with the contraction of the telescopic end of the hydraulic rod, the cross beam drives the connecting rod to move downward. Under the action of the self-gravity of the connecting rod, the connecting rod drives the elastic wires to rotate in the reverse direction to reset. Then, the connecting rod drives the elastic wires to swing reciprocally, so that the moving elastic wires are always in a dynamic state, which is convenient for processing the pulverized coal clusters.

[0027] Sixth, for the vertical magnetic separator used for iron removal of pulverized coal processed from slime, as the pulverized coal slides off from the first magnetic disk, the second magnetic disk and the third magnetic disk, the pulverized coal falls onto the discharge plate, and the pulverized coal accumulates. With the discharge plate installed obliquely, the pulverized coal slides downward along the discharge plate until it is discharged from the interior of the machine housing. And two symmetric baffles are used to block the pulverized coal falling on the top of the discharge plate, so that the pulverized coal is not easy to scatter, which further promotes the discharge of the pulverized coal.

[0028] VII. For the vertical magnetic separator used for iron removal of pulverized coal processed from slime, by pressing the arc surface outside the pressing block to contact the top end of the pressure-receiving rod, the pressure-receiving rod is subjected to the downward pressing force of the pressing block. The pressure-receiving rod applies the pressure to the sliding beam, and through the guidance of the inclined strip-shaped holes, the sliding beam drives the pressure-receiving rod and the connecting seat to move obliquely downward, and the elastic piece is compressed. As the connecting seat moves obliquely downward, the bottom of the material-pushing piece contacts the top of the discharge plate, and by continuously moving the material-pushing piece downward, the pulverized coal on the top of the discharge plate can be pushed downward, and it is not easy to have the situation of pulverized coal accumulation.

[0029] VIII. For the vertical magnetic separator used for iron removal of pulverized coal processed from slime, as the pressing block separates from the top of the pressure-receiving rod, the pressing force received by the pressure-receiving rod disappears, and under the elastic force of the elastic piece, the sliding beam drives the pressure-receiving rod and the connecting seat to move obliquely upward for resetting, so that the material-pushing piece is lifted, facilitating the continuous downward movement of the pulverized coal falling on the top of the discharge plate, and it is not easy to have the situation of the pulverized coal being pulled back.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] The first embodiment is as Figures 1 to 5 shown. The present invention provides a technical solution:

[0043] A vertical magnetic separator for iron removal of pulverized coal in slime processing, comprising:

[0044] A machine housing 1, a feeding hopper 2 is fixedly installed at the middle of the top of the machine housing 1, and a rectangular opening 3 is formed at the side of the surface of the machine housing 1;

[0045] An iron removal mechanism 4, which is used for magnetic separation and iron removal of pulverized coal, and the iron removal mechanism 4 is installed at the middle of the inside of the machine housing 1;

[0046] Among them, the iron removal mechanism 4 includes a bracket 41 and a scraping component 49. Both ends of the surface of the bracket 41 are fixedly installed on the inner wall of the casing 1. The scraping component 49 is installed on the inner wall of the casing 1, and the position of the scraping component 49 corresponds to the position of the bracket 41. A first driver 42, a second driver 43, and a third driver 44 are sequentially installed on the top of the bracket 41. A first magnetic disk 45 is installed at the output end of the first driver 42, a second magnetic disk 46 is installed at the output end of the second driver 43, and a third magnetic disk 47 is installed at the output end of the third driver 44. A pressing block 48 is fixedly connected to the edge of the bottom of the second magnetic disk 46. By presenting an overlapping state among the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47, when pulverized coal falls on the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47, the iron substances can be magnetically attracted. Moreover, since the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47 are inclinedly installed, the pulverized coal that falls on the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47 can fall off, so that the pulverized coal and the iron substances can be separated. And by the staff turning on the first driver 42, the second driver 43, and the third driver 44 to work, the output end of the first driver 42 drives the first magnetic disk 45 to rotate counterclockwise, the output end of the second driver 43 drives the second magnetic disk 46 to rotate counterclockwise, and the output end of the third driver 44 drives the third magnetic disk 47 to rotate counterclockwise. Then, by the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47 rotating together, the iron substances magnetically attracted by the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47 can be transferred;

[0047] The first driver 42, the second driver 43, and the third driver 44 are evenly installed on the top of the bracket 41, and the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47 are all inclinedly installed.

[0048] There are four pressing blocks 48, and the four pressing blocks 48 are evenly installed at the edge of the bottom of the second magnetic disk 46.

[0049] The scraping component 49 includes a V-shaped plate 491. The bent part at the bottom of the V-shaped plate 491 is fixedly installed on the surface of the casing 1, and the V-shaped plate 491 and the bracket 41 are installed at the same height. The top end of the V-shaped plate 491 penetrates the surface of the casing 1 and extends into its interior. A right-angle support rod 492 is fixedly connected to the inner side surface of the V-shaped plate 491. The right-angle support rod 492 is installed inside the casing 1. The top end of the right-angle support rod 492 is fixedly connected to a scraping plate 493. The position of the scraping plate 493 corresponds to the positions of the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47. As the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47 rotate the magnetically attracted iron substances, by using the bottom of the scraping plate 493 to fit with the top of the magnetic disks, and scraping plates 493 are installed on the tops of all three magnetic disks, namely the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47, the iron substances magnetically attracted to the tops of the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47 can be scraped off by the scraping plate 493. Under the guiding action of the scraping plate 493, the iron substances fall into the interior of the V-shaped plate 491. By using the inclined installation of the V-shaped plate 491, the iron substances are discharged from the interior of the casing 1.

[0050] There are three V-shaped plates 491, and the three V-shaped plates 491 are evenly installed on the surface of the casing 1 and are inclinedly installed.

[0051] Second Embodiment, on the basis of the first embodiment, please refer to Figures 1 to 8 as shown in

[0052] a material guiding mechanism 5. The material guiding mechanism 5 is used for preprocessing pulverized coal. The material guiding mechanism 5 is installed inside the casing 1 and is installed directly below the feed hopper 2;

[0053] Among them, the material guiding mechanism 5 includes a diversion plate 51 and a material spreading component 57. The diversion plate 51 is fixedly installed on the inner wall of the casing 1. The material spreading component 57 is installed at the top of the inner cavity of the casing 1. A hydraulic rod 52 is installed at the bottom of the diversion plate 51. The telescopic end of the hydraulic rod 52 is fixedly connected to a cross beam 53. A connecting rod 54 is hinged to the outer circular surface of the cross beam 53. An elastic wire 55 is fixedly connected to the outer circular surface of the connecting rod 54. A top plate 56 is fixedly connected to the middle of the top of the cross beam 53. As the reciprocating moving spreading plate 573 and the dividing sheet 575 spread the pulverized coal raw materials, the pulverized coal raw materials fall onto the elastic wire 55. By using the elastic wire 55 evenly distributed on the connecting rod 54 to form a wire mesh, the pulverized coal clusters attached together can be broken. The pulverized coal passes through the elastic wire 55 and falls onto the diversion plate 51. Then, through the diversion of the diversion plate 51, the pulverized coal is conveyed to the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47, facilitating subsequent magnetic separation for iron removal.

[0054] The bottom end of the deflector 51 extends above the first disk 45, above the second disk 46, and above the third disk 47. The connecting rod 54 and the elastic wire 55 are installed directly above the deflector 51. The top end of the connecting rod 54 fits against the inclined surface of the inner wall of the casing 1. By extending the telescopic end of the hydraulic rod 52, the cross beam 53 is pushed upward, so that the connecting rod 54 can move upward. By using the fact that the top end of the connecting rod 54 fits against the inclined surface of the inner wall of the casing 1, as the connecting rod 54 continues to rise, the connecting rod 54 can drive the elastic wire 55 to rotate and adjust the angle. Along with the contraction of the telescopic end of the hydraulic rod 52, the cross beam 53 will drive the connecting rod 54 to move downward. Under the action of the self-gravity of the connecting rod 54, the connecting rod 54 drives the elastic wire 55 to rotate in the reverse direction for resetting. The connecting rod 54 can drive the elastic wire 55 to swing back and forth, so that the dynamic elastic wire 55 is always in a dynamic state, which is convenient for processing the pulverized coal mass.

[0055] The material spreading assembly 57 includes a square support rod 571. The square support rod 571 is fixedly installed on the inner wall of the casing 1 through a base frame. A slider 572 is slidably installed at the middle of the surface of the square support rod 571. One end of the slider 572 away from the square support rod 571 is fixedly connected to a material spreading plate 573. The material spreading plate 573 is installed directly below the feed hopper 2. An elastic reset strip 574 is fixedly connected between the surface of the slider 572 and the base frame at the end of the square support rod 571. A material dividing piece 575 is fixedly connected to the bent portion of the surface of the material spreading plate 573. A linear hole 576 is formed in the surface of the material spreading plate 573, and the linear hole 576 is formed at the position of the bottom end of the material dividing piece 575. A ball head rod 577 is fixedly connected to the middle of the bottom of the material spreading plate 573. The staff starts the hydraulic rod 52 to work. By extending the extending end of the hydraulic rod 52, the cross beam 53 can be pushed upward, so that the top plate 56 is pushed upward together with the cross beam 53. The upward pushing force can be applied to the ball head rod 577 through the top plate 56. Combined with the fixed connection between the slider 572 and the material spreading plate 573 and under the guiding action of the square support rod 571, the slider 572 and the material spreading plate 573 move horizontally as a whole, and the elastic reset strip 574 is compressed. By contracting the extending end of the hydraulic rod 52, the cross beam 53 and the top plate 56 move downward together. The upward pushing force of the top plate 56 on the ball head rod 577 disappears. Under the elastic force of the elastic reset strip 574, the slider 572 and the material spreading plate 573 move in the reverse direction for resetting together, and the material spreading plate 573 will drive the material dividing piece 575 to move together. The pulverized coal raw material falling from the feed hopper 2 can be affected by the linear reciprocating movement of the material spreading plate 573 and the material dividing piece 575, so that the pulverized coal raw material can be sprinkled and evenly discharged.

[0056] The elastic reset strip 574 is arc-shaped. The material dividing pieces 575 are evenly distributed at the bent portion of the surface of the material spreading plate 573. The ball head rod 577 is installed obliquely.

[0057] For the third embodiment, on the basis of the first and second embodiments, please refer to Figures 1 to 10 as shown in:

[0058] A discharging mechanism 6 is installed at the bottom of the inner cavity of the casing 1. The discharging mechanism 6 includes a discharging plate 61. A baffle 62 is fixedly connected to the side of the top of the discharging plate 61. An inclined strip-shaped hole 63 is formed in the middle of the surface of the baffle 62. A sliding beam 64 is slidably installed on the surface of the baffle 62 through the inclined strip-shaped hole 63. A pressure-receiving rod 65 is fixedly installed in the middle of the top of the sliding beam 64. The pressure-receiving rod 65 is installed directly below the pressing block 48. A connecting seat 66 is fixedly installed on the surface of the sliding beam 64, and the position of the connecting seat 66 corresponds to the position of the pressure-receiving rod 65. A pushing piece 67 is fixedly installed at the bottom end of the connecting seat 66. An elastic ring 68 is fixedly connected between the top of the connecting seat 66 and the outer cylindrical surface of the pressure-receiving rod 65. An elastic piece 69 is fixedly connected between the end of the surface of the sliding beam 64 and the surface of the baffle 62. As the pulverized coal slides down from the first magnetic disk 45, the second magnetic disk 46, and the third magnetic disk 47, the pulverized coal falls onto the discharging plate 61, causing the pulverized coal to accumulate. By using the inclined installation of the discharging plate 61, the pulverized coal slides down along the discharging plate 61 until it is discharged from the inside of the casing 1. And by using two symmetrical baffles 62 to block the pulverized coal falling onto the top of the discharging plate 61, the pulverized coal is not easily scattered.

[0059] There are two baffles 62, and the two baffles 62 are symmetrically installed along the central axis of the middle of the discharging plate 61. The sliding beam 64 is installed directly above the discharging plate 61. As the second magnetic disk 46 rotates, the pressing block 48 can be driven to rotate in a circle, and through the contact between the arc surface outside the pressing block 48 and the top end of the pressure-receiving rod 65, the pressure-receiving rod 65 receives a downward pressing force from the pressing block 48. The pressure-receiving rod 65 applies the pressure to the sliding beam 64, and through the guidance of the inclined strip-shaped hole 63, the sliding beam 64 drives the pressure-receiving rod 65 and the connecting seat 66 to move obliquely downward, and the elastic piece 69 is compressed. As the connecting seat 66 moves obliquely downward, the bottom of the pushing piece 67 contacts the top of the discharging plate 61, and by continuously moving the pushing piece 67 downward, the pulverized coal on the top of the discharging plate 61 can be pushed downward.

[0060] As the pressing block 48 disengages from the top of the pressure-receiving rod 65, the pressing force received by the pressure-receiving rod 65 disappears, and under the elastic force of the elastic piece 69, the sliding beam 64 drives the pressure-receiving rod 65 and the connecting seat 66 to move obliquely upward for resetting, so that the pushing piece 67 is lifted, facilitating the continuous downward movement of the pulverized coal falling onto the top of the discharging plate 61 and not easily pulling the pulverized coal in the reverse direction.

[0061] During use, first, the staff puts the pulverized coal raw material to be processed into the feed hopper 2. At this time, the staff starts the hydraulic rod 52 to work. By extending the extending end of the hydraulic rod 52, the cross beam 53 can be pushed upward, so that the jacking plate 56 is pushed upward together with the cross beam 53. Then, an upward jacking force can be applied to the ball head rod 577 through the jacking plate 56. Considering the fixed connection between the slider 572 and the material spreading plate 573 and the guiding effect of the square support rod 571, the slider 572 and the material spreading plate 573 move horizontally as a whole. And the elastic reset strip 574 is compressed. By contracting the extending end of the hydraulic rod 52, the cross beam 53 and the jacking plate 56 move downward together. The upward jacking force of the jacking plate 56 on the ball head rod 577 disappears. Under the elastic force of the elastic reset strip 574, the slider 572 and the material spreading plate 573 move in the reverse direction to reset. And the material spreading plate 573 drives the material dividing piece 575 to move together. Then, the pulverized coal raw material falling from the feed hopper 2 is affected by the linear reciprocating movement of the material spreading plate 573 and the material dividing piece 575, and the pulverized coal raw material can be sprinkled, so that the pulverized coal raw material is evenly fed;

[0062] Moreover, by extending the telescopic end of the hydraulic rod 52, the cross beam 53 is pushed upward. Then, the connecting rod 54 can be moved upward. And the top end of the connecting rod 54 is attached to the inclined surface of the inner wall of the casing 1. As the connecting rod 54 continues to rise, the connecting rod 54 drives the elastic wire 55 to rotate and adjust the angle. Along with the contraction of the telescopic end of the hydraulic rod 52, the cross beam 53 drives the connecting rod 54 to move downward. Under the action of the self-gravity of the connecting rod 54, the connecting rod 54 drives the elastic wire 55 to rotate in the reverse direction to reset. Then, the connecting rod 54 drives the elastic wire 55 to swing reciprocally, so that the moving elastic wire 55 is always in a dynamic state, which is convenient for processing the pulverized coal mass;

[0063] At the same time, as the reciprocating moving material spreading plate 573 and material dividing piece 575 sprinkle the pulverized coal raw material, the pulverized coal raw material falls on the elastic wire 55. And the elastic wire 55 is evenly distributed on the connecting rod 54 to form a wire mesh. Then, the pulverized coal mass attached together can be broken. And the pulverized coal passes through the elastic wire 55 and falls on the diversion plate 51. Then, through the diversion of the diversion plate 51, the pulverized coal is conveyed to the first magnetic disk 45, the second magnetic disk 46 and the third magnetic disk 47;

[0064] And by presenting an overlapping state among the first disk 45, the second disk 46, and the third disk 47, when pulverized coal falls onto the first disk 45, the second disk 46, and the third disk 47, the iron substances can be magnetically attracted. Moreover, since the first disk 45, the second disk 46, and the third disk 47 are installed obliquely, the pulverized coal falling onto the first disk 45, the second disk 46, and the third disk 47 can fall off, enabling the separation of the pulverized coal and the iron substances. Then, the staff starts the first driver 42, the second driver 43, and the third driver 44 to work. The output end of the first driver 42 drives the first disk 45 to rotate counterclockwise, the output end of the second driver 43 drives the second disk 46 to rotate counterclockwise, and the output end of the third driver 44 drives the third disk 47 to rotate counterclockwise. By rotating the first disk 45, the second disk 46, and the third disk 47 together, the magnetically attracted iron substances on the first disk 45, the second disk 46, and the third disk 47 can be transferred;

[0065] As the first disk 45, the second disk 46, and the third disk 47 rotate the magnetically attracted iron substances, the bottom of the scraping plate 493 is attached to the top of the disks. Since the scraping plate 493 is installed on the top of each of the three disks, namely the first disk 45, the second disk 46, and the third disk 47, the iron substances magnetically attracted to the top of the first disk 45, the second disk 46, and the third disk 47 can be scraped off by the scraping plate 493. Under the guiding action of the scraping plate 493, the iron substances fall into the interior of the V-shaped plate 491. And because the V-shaped plate 491 is installed obliquely, the iron substances are discharged from the interior of the casing 1;

[0066] Moreover, as the pulverized coal slides off the first disk 45, the second disk 46, and the third disk 47, the pulverized coal falls onto the discharge plate 61, causing the pulverized coal to accumulate. Since the discharge plate 61 is installed obliquely, the pulverized coal slides downward along the discharge plate 61 until it is discharged from the interior of the casing 1. And two symmetric baffles 62 are used to block the pulverized coal falling onto the top of the discharge plate 61, preventing the pulverized coal from scattering easily.

[0067] As the second disk 46 rotates, the pressing block 48 can be driven to rotate in a circular motion. Through the contact between the arc surface on the outside of the pressing block 48 and the top end of the pressure-receiving rod 65, the pressure-receiving rod 65 receives a downward pressing force from the pressing block 48. The pressure-receiving rod 65 applies the pressure to the sliding beam 64. Under the guiding of the inclined strip-shaped hole 63, the sliding beam 64 drives the pressure-receiving rod 65 and the connecting seat 66 to move obliquely downward, compressing the elastic piece 69. As the connecting seat 66 moves obliquely downward, the bottom of the pushing plate 67 contacts the top of the discharge plate 61. By continuously moving the pushing plate 67 downward, the pulverized coal on the top of the discharge plate 61 can be pushed downward.

[0068] As the pressing block 48 disengages from the top of the pressure-receiving rod 65, the pressing force applied to the pressure-receiving rod 65 disappears. Under the elastic force of the elastic piece 69, the sliding beam 64 drives the pressure-receiving rod 65 and the connecting seat 66 to move in an obliquely upward direction for resetting, so that the pushing piece 67 is lifted, facilitating the continuous downward movement of the pulverized coal falling on the top of the discharge plate 61.
