Description

Technical Field

[0001] This invention relates to the field of magnesium powder preparation technology, and in particular to a continuous nano-magnesium powder preparation device and method. Background Technology

[0002] In industrial production, mechanical ball milling is an important method for mass production of nano-sized magnesium powder due to its low equipment requirements.

[0003] Existing ball milling devices for preparing nano-magnesium powder require opening the device after grinding to remove the magnesium powder inside. This is inconvenient for collecting magnesium powder, and larger magnesium powder particles are easily removed along with it, resulting in poor quality magnesium powder. At the same time, removing magnesium powder in this way can easily introduce impurities, leading to a decrease in the purity of the magnesium powder and making the prepared magnesium powder unusable for subsequent production processes. The removal of impurities is also quite troublesome, which is not conducive to the preparation of magnesium powder. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a continuous nano-magnesium powder preparation device and method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A continuous nano-magnesium powder preparation device and method, comprising:

[0007] A fixed base and a ball mill cylinder are provided. A fixed bracket is fixedly installed on the fixed base, and the fixed bracket is rotatably sleeved on the outside of the ball mill cylinder. A power structure is fixedly installed on the fixed base.

[0008] The collection structure includes a fixed box fixedly connected to a fixed base. The ball mill cylinder is fixedly connected to the fixed box via a connecting pipe. An air inlet pipe and an air outlet pipe are fixedly connected to the ball mill cylinder and the fixed box, respectively. A collection groove communicating with the air outlet pipe is opened inside the fixed box. The collection box is slidably installed on the inner wall of the collection groove. A rotating cylinder is rotatably installed on the inner wall of the fixed box. A connecting bracket is fixedly connected to the rotating cylinder. A rotating rod is fixedly installed on the connecting bracket. An impact fan blade is fixedly connected to the rotating rod. An auxiliary structure is slidably installed inside the fixed box.

[0009] Preferably, the auxiliary structure includes a fixed cylinder, the inner wall of which is slidably connected to a rotating rod via a movable block. An adjusting plate is rotatably sleeved on the fixed cylinder, and the adjusting plate is slidably connected to the inner wall of the collection trough via a sliding bracket. A central shaft is rotatably mounted on the adjusting plate, and an adjusting rod is slidably mounted on the central shaft. An adjusting shaft is fixedly connected to the adjusting rod and passes through it. An adjusting block is rotatably connected to the outer side of the adjusting shaft, and a fixed scraper is fixedly connected to the adjusting block. The adjusting rod adopts a telescopic structure, and a return spring is fixedly mounted on the inner wall of the adjusting rod. A transmission structure is fixedly mounted on the fixed cylinder.

[0010] Preferably, the transmission structure includes a fixed gear fixedly sleeved on the outside of the fixed cylinder, a connecting shaft rotatably connected to the adjusting plate, a connecting gear meshing with the fixed gear fixedly sleeved on the connecting shaft, a connecting disc fixedly connected to the connecting gear, a connecting block fixedly connected to the connecting disc, and the connecting block rotatably connected to the adjusting rod.

[0011] Preferably, a reciprocating lead screw is fixedly connected to the rotating rod, a lead screw slider is mechanically fitted to the outer side of the reciprocating lead screw, the side wall of the lead screw slider is fixedly connected to the adjusting plate through a mounting rod, a fixing sleeve is sleeved on the outer side of the reciprocating lead screw, a connecting rod is slidably connected to the inner wall of the reciprocating lead screw, a fixing block corresponding to the air outlet pipe is fixedly installed on the connecting rod, and an adjusting spring is fixedly installed between the connecting rod and the inner wall of the reciprocating lead screw.

[0012] Preferably, a cleaning structure is fixedly installed inside the fixed box. The cleaning structure includes a fixed tube fixedly installed on the inner wall of the fixed box, a placement plate slidably sleeved on the outer side of the fixed tube, an adsorption plate slidably connected to the inner wall of the rotating cylinder, the adsorption plate being rotatably connected to the placement plate, a connecting scraper corresponding to the fixed box being fixedly installed on the placement plate, and a fixing spring being fixedly connected between the placement plate and the inner wall of the rotating cylinder.

[0013] Preferably, sealing flanges are fixedly installed at the connection points of the connecting pipe, air inlet pipe, and air outlet pipe with the corresponding ball mill cylinder and fixed box.

[0014] Preferably, the power structure includes a motor fixedly mounted on a fixed base, and a rotating rod is fixedly connected to the output end of the motor. The rotating rod and the ball mill cylinder are connected by a belt drive assembly.

[0015] A method for preparing continuous nano-magnesium powder includes the following steps:

[0016] S1. Feed the magnesium block into the ball mill cylinder, start the motor, and simultaneously introduce inert gas into the ball mill cylinder. After the motor starts, its output end drives the rotating rod to rotate. Under the action of the belt drive assembly, the ball mill cylinder rotates together with the rotating rod, causing the cast iron balls inside the ball mill cylinder to rotate and ball mill the magnesium block, grinding it into nano-sized magnesium powder. At the same time, when the magnesium powder particles are ground to the nano-scale, the magnesium powder will be blown towards the connecting pipe by the flow of inert gas and finally enter the fixed box for collection.

[0017] S2. After the magnesium powder enters the fixed box, it first enters the inner side of the rotating cylinder through the fixed tube. The iron powder in the magnesium powder is attracted by the adsorption plate and adsorbed on the adsorption plate. The magnesium powder with higher purity flows upward with the gas. During the gas flow, the gas blows towards the impact fan blade, causing the impact fan blade to rotate, which drives the rotating rod to rotate together, causing the connecting bracket and the rotating cylinder to rotate. The rotation of the rotating cylinder causes the gas to rotate as well. The rotation of the gas can play a centrifugal effect, causing the magnesium powder to gather to the outside of the gas. This also facilitates the removal of iron powder. After the gas enters the inner side of the collection tank, the magnesium powder, under centrifugal treatment, is close to the inner wall of the collection tank and cannot move to the outside of the fixed box. The gas is discharged from the outlet pipe.

[0018] S3. During the rotation of the rotating rod, the fixed cylinder rotates accordingly, causing the fixed gear fixedly sleeved on the outside of the fixed cylinder to rotate as well. This causes the connecting gear meshing with the fixed gear to rotate, resulting in the rotation of the connecting shaft. This, in turn, causes the connecting disc fixedly mounted on the connecting shaft to rotate. The connecting block mounted on the connecting disc rotates in a circular motion along with the connecting disc, causing the end of the adjusting rod connected to the connecting block to also rotate in a circular motion. Therefore, the adjusting rod as a whole will rotate back and forth around the central axis, causing the fixed scraper mounted on the central shaft to rotate back and forth accordingly. The elastic force of the return spring causes the fixed scraper to rotate back and forth. The plate can always be pressed against the inner wall of the collection tank, and the back-and-forth movement of the fixed scraper can scrape the magnesium powder adhering to the inner wall of the collection tank into the collection box for collection. When the rotating drum rotates, the adsorption plate will also rotate, while the connecting scraper does not rotate. Therefore, the connecting scraper will scrape the iron powder on the adsorption plate and let it fall onto the placement plate. The top of the placement plate is located below the fixed tube, so the iron powder on the placement plate is not easily affected by the lift and moves upward. Moreover, as the amount of iron powder increases, the fixed spring contracts and the placement plate moves downward, further preventing the iron powder from being carried away by the gas.

[0019] S4. When the rotating rod rotates, the reciprocating lead screw fixedly installed on the rotating rod also rotates, causing the lead screw slider, which is mechanically coordinated with the reciprocating lead screw, to move up and down. Under the action of the mounting rod, the adjusting plate moves up and down accordingly, driving the fixed scraper to move up and down as well. The up and down movement of the fixed scraper prevents the magnesium powder from adhering to the fixed scraper when scraping it. At the same time, as the lead screw slider moves, it pushes the fixed block, causing the fixed block to move upward and block the air outlet. When the airflow reaches the vicinity of the air outlet, it cannot continue to flow. Therefore, the magnesium powder is no longer lifted by the gas and falls down, making it easier for the magnesium powder to fall into the collection box. Then the lead screw slider moves downward, and the fixed block also moves downward under the action of the adjusting spring, returning to its original position.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Inert gas is introduced into the device. The gas can blow out the tiny magnesium powder particles, while the airflow cannot blow out the larger magnesium powder particles. Therefore, the quality of the collected magnesium powder is higher. At the same time, after the magnesium powder enters the fixed box, it can be centrifuged to move the magnesium powder to the outside of the gas, that is, to the inner wall of the collection box, while the gas is discharged from the gas outlet. The collection of magnesium powder is more convenient.

[0022] 2. During the gas flow process, the outlet pipe can be blocked intermittently. Therefore, when the gas flows to the outlet pipe, it will be unable to continue flowing. As a result, the magnesium powder in the collection tank will lose lift and fall. With the movement of the fixed scraper, the magnesium powder falls into the collection box, which further facilitates the collection of magnesium powder.

[0023] 3. By installing an adsorption plate, iron powder in magnesium powder can be adsorbed. Moreover, magnesium powder and iron powder are suspended in the gas. Combined with centrifugal rotation, the removal of iron powder can be more complete, thereby improving the purity of magnesium powder and facilitating its preparation. Attached Figure Description

[0034] Reference Figures 1-9 A continuous nano-magnesium powder preparation device and method, comprising:

[0035] The fixed base 1 and the ball mill cylinder 3 are fixedly installed. A fixed bracket 2 is fixedly installed on the fixed base 1 and the fixed bracket 2 is rotatably sleeved on the outside of the ball mill cylinder 3. A power structure is fixedly installed on the fixed base 1.

[0036] like Figure 3 and Figure 4As shown, the collection structure 6 includes a fixed box 5 fixedly connected to the fixed base 1. The ball mill cylinder 3 is fixedly connected to the fixed box 5 via a connecting pipe 4. An inlet pipe and an outlet pipe are fixedly connected to the ball mill cylinder 3 and the fixed box 5, respectively. A collection groove 9 communicating with the outlet pipe is opened inside the fixed box 5. The collection groove 9 is located at the upper end of the fixed box 5. After the gas and magnesium powder enter the collection groove 9, under centrifugal force, the gas will carry the magnesium powder to diffuse to both sides, so that the magnesium powder can fall into the collection box 13. The collection box 13 is slidably installed on the inner wall of the collection groove 9. A rotating cylinder 61 is rotatably installed on the inner wall of the fixed box 5. The rotating cylinder 61 is a cylinder with its upper and lower ends connected. It is installed on the lower inner wall of the fixed box 5, and its top end extends into the collection groove 9. The side wall of the rotating cylinder 61 is in contact with the inner side wall of the fixed box 5. Therefore, after the gas enters the fixed box 5, it will pass through the inside of the rotating cylinder 61. A connecting bracket 62 is fixedly connected to the rotating cylinder 61. A rotating rod 63 is fixedly installed on the connecting bracket 62. An impact fan blade 64 is fixedly connected to the rotating rod 63. The impact fan blade 64 is a prior art technology. Through the arc shape of the outer side of the fan blade, the gas will cause the impact fan blade 64 to rotate when it passes through the impact fan blade 64. An auxiliary structure 7 is slidably installed inside the fixed box 5.

[0037] After the gas enters the fixed box 5, it impacts the impact fan blade 64, causing the impact fan blade 64 to rotate, which in turn drives the rotating rod 63 to rotate, causing the connecting bracket 62 and the rotating cylinder 61 to rotate as well. The rotation of the rotating cylinder 61 causes the gas to rotate as well. The rotation of the gas has a centrifugal effect, causing the magnesium powder to gather to the outside of the gas, which also facilitates the removal of iron powder. After the gas enters the inside of the collection tank 9, the magnesium powder, under centrifugal treatment, is close to the inner wall of the collection tank 9 and cannot move to the outside of the fixed box 5. The gas is then discharged from the outlet pipe.

[0038] like Figure 5 and Figure 7 As shown, the auxiliary structure 7 includes a fixed cylinder 71. The inner wall of the fixed cylinder 71 is slidably connected to the rotating rod 63 via a moving block. An adjusting plate 73 is rotatably sleeved on the fixed cylinder 71, and the adjusting plate 73 is slidably connected to the inner wall of the collection tank 9 via a sliding bracket 72. A central shaft 79 is rotatably mounted on the adjusting plate 73, and an adjusting rod 78 is slidably mounted on the central shaft 79. An adjusting shaft 77 is fixedly connected to the adjusting rod 78 and passes through it. An adjusting block 76 is rotatably connected to the outer side of the adjusting shaft 77, and a fixed scraper 75 is fixedly connected to the adjusting block 76. The adjusting rod 78 adopts a telescopic structure, and a return spring is fixedly installed on the inner wall of the adjusting rod 78. A transmission structure is fixedly installed on the fixed cylinder 71.

[0039] Under the action of the transmission structure, the fixed scraper 75 installed on the central shaft 79 moves back and forth. The elastic force of the return spring allows the fixed scraper 75 to keep against the inner wall of the collection tank 9. The back and forth movement of the fixed scraper 75 can scrape the magnesium powder adhering to the inner wall of the collection tank 9 into the collection box 13 to collect the magnesium powder. At the same time, under the action of the mounting rod 714, the adjusting plate 73 moves up and down, which drives the fixed scraper 75 to move up and down. The up and down movement of the fixed scraper 75 can prevent the magnesium powder from adhering to the fixed scraper 75 when scraping off the magnesium powder.

[0040] like Figure 5 , Figure 6 and Figure 7 As shown, the transmission structure includes a fixed gear 74 fixedly sleeved on the outside of the fixed cylinder 71, a connecting shaft 711 rotatably connected to the adjusting plate 73, a connecting gear 710 fixedly sleeved on the connecting shaft 711 and meshing with the fixed gear 74, a connecting disk 712 fixedly connected to the connecting gear 710, a connecting block 713 fixedly connected to the connecting disk 712, and the connecting block 713 rotatably connected to the adjusting rod 78.

[0041] The fixed cylinder 71 rotates, causing the fixed gear 74, which is fixedly sleeved on the outside of the fixed cylinder 71, to rotate as well. This causes the connecting gear 710, which meshes with the fixed gear 74, to rotate, making the connecting shaft 711 rotate. This causes the connecting disc 712, which is fixedly mounted on the connecting shaft 711, to rotate. The connecting block 713, which is rotatably mounted on the connecting disc 712, moves in a circular motion along with the connecting disc 712. This causes the end of the adjusting rod 78 connected to the connecting block 713 to also move in a circular motion. Therefore, the adjusting rod 78 as a whole will rotate back and forth around the central axis 79.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, a reciprocating lead screw 65 is fixedly connected to the rotating rod 63. The fixed cylinder 71 is entirely sleeved on the outside of the reciprocating lead screw 65. Therefore, when the fixed cylinder 71 rotates and moves, there will be no interference between its movement and that of the lead screw slider 66 and the reciprocating lead screw 65. The outer side of the reciprocating lead screw 65 is mechanically fitted with the lead screw slider 66. The side wall of the lead screw slider 66 is fixedly connected to the adjusting plate 73 through the mounting rod 714. The fixed cylinder 71 is sleeved on the outside of the reciprocating lead screw 65. A connecting rod 67 is slidably connected to the inner wall of the reciprocating lead screw 65. A fixed plug 68 corresponding to the air outlet pipe is fixedly installed on the connecting rod 67. An adjusting spring is fixedly installed between the connecting rod 67 and the inner wall of the reciprocating lead screw 65.

[0043] When the rotating rod 63 rotates, the reciprocating screw 65 fixedly installed on the rotating rod 63 also rotates, causing the screw slider 66, which is mechanically engaged with the reciprocating screw 65, to move up and down. As the screw slider 66 moves, it pushes the fixed block 68, causing the fixed block 68 to move upward and block the air outlet. When the airflow reaches the vicinity of the air outlet, it cannot continue to flow. Therefore, the magnesium powder is no longer lifted by the gas and falls down, making it easier for the magnesium powder to fall into the collection box 13. Then the screw slider 66 moves downward, and the fixed block 68 also moves downward under the action of gravity.

[0044] like Figure 8 As shown, a cleaning structure 8 is fixedly installed inside the fixed box 5. The cleaning structure 8 includes a fixed tube 81 fixedly installed on the inner wall of the fixed box 5. A placement plate 82 is slidably sleeved on the outer side of the fixed tube 81. An adsorption plate 83 is slidably connected to the inner wall of the rotating cylinder 61. A magnet is installed on the adsorption plate 83. The magnetic force of the magnet can adsorb iron powder onto the adsorption plate 83. The adsorption plate 83 is rotatably connected to the placement plate 82. A connecting scraper 84 corresponding to the adsorption plate 83 is fixedly installed on the placement plate 82. A fixing spring 85 is fixedly connected between the placement plate 82 and the inner wall of the fixed box 5.

[0045] When the rotating cylinder 61 rotates, the adsorption plate 83 also rotates, while the connecting scraper 84 does not rotate. Therefore, the connecting scraper 84 scrapes the iron powder on the adsorption plate 83 and it falls onto the placement plate 82. The top of the placement plate 82 is located below the fixed tube 81, so the iron powder on the placement plate 82 is not easily affected by the lift and moves upward. Moreover, as the amount of iron powder increases, the fixed spring 85 contracts and the placement plate 82 moves downward, further preventing the iron powder from being carried away by the gas.

[0046] like Figure 1 and Figure 2 As shown, sealing flanges are fixedly installed at the connection points of the connecting pipe 4, the inlet pipe and the outlet pipe with the corresponding ball mill cylinder 3 and the fixed box 5 to seal the device and prevent gas leakage.

[0047] like Figure 1 As shown, the power structure includes a motor 10 fixedly mounted on a fixed base 1. A rotating rod 11 is fixedly connected to the output end of the motor 10. The rotating rod 11 and the ball milling cylinder 3 are connected by a belt drive assembly 12. After the motor 10 is started, its output end drives the rotating rod 11 to rotate. Under the action of the belt drive assembly 12, the ball milling cylinder 3 rotates together with the rotating rod 11, causing the cast iron balls inside the ball milling cylinder 3 to rotate and ball mill the magnesium block into nano-sized magnesium powder.

[0048] A method for preparing continuous nano-magnesium powder includes the following steps:

[0049] S1. The magnesium block is fed into the ball mill cylinder 3, the motor 10 is started, and inert gas is introduced into the ball mill cylinder 3 at the same time. After the motor 10 starts, its output end drives the rotating rod 11 to rotate. Under the action of the belt drive assembly 12, the ball mill cylinder 3 rotates with the rotating rod 11, causing the cast iron ball inside the ball mill cylinder 3 to rotate and ball mill the magnesium block, grinding it into nano-sized magnesium powder. At the same time, when the magnesium powder particles are ground to the nano-sized, the magnesium powder will be blown towards the connecting pipe 4 by the flow of inert gas and finally enter the fixed box 5 for collection.

[0050] S2. After the magnesium powder enters the fixed box 5, it first enters the inner side of the rotating cylinder 61 through the fixed pipe 81. The iron powder in the magnesium powder will be attracted by the adsorption plate 83 and adsorbed on the adsorption plate 83. The magnesium powder with higher purity flows upward with the gas. During the gas flow, the gas will blow towards the impact fan blade 64, causing the impact fan blade 64 to rotate. The gas will impact the impact fan blade 64, causing the impact fan blade 64 to rotate, driving the rotating rod 63 to rotate together, causing the connecting bracket 62 and the rotating cylinder 61 to rotate accordingly. The rotation of the rotating cylinder 61 will also cause the gas to rotate. The rotation of the gas can play a centrifugal effect, causing the magnesium powder to gather to the outside of the gas, which also facilitates the removal of iron powder. After the gas enters the inner side of the collection tank 9, the magnesium powder, under centrifugal treatment, is close to the inner wall of the collection tank 9 and cannot move to the outside of the fixed box 5. The gas is discharged from the gas outlet pipe.

[0051] S3. During the rotation of the rotating rod 63, the fixed cylinder 71 rotates accordingly, causing the fixed gear 74, which is fixedly sleeved on the outside of the fixed cylinder 71, to rotate as well. This causes the connecting gear 710, which meshes with the fixed gear 74, to rotate, resulting in the rotation of the connecting shaft 711. This, in turn, causes the connecting disc 712, which is fixedly mounted on the connecting shaft 711, to rotate. The connecting block 713, which is rotatably mounted on the connecting disc 712, moves in a circular motion along with the connecting disc 712. This causes the end of the adjusting rod 78 connected to the connecting block 713 to also move in a circular motion. Therefore, the adjusting rod 78 as a whole will rotate back and forth around the central shaft 79, causing the fixed scraper 75 mounted on the central shaft 79 to rotate back and forth accordingly. The return spring... The elasticity of the fixed scraper 75 allows it to remain pressed against the inner wall of the collection tank 9. The back-and-forth movement of the fixed scraper 75 scrapes the magnesium powder adhering to the inner wall of the collection tank 9 into the collection box 13 for collection. When the rotating cylinder 61 rotates, the adsorption plate 83 also rotates, while the connecting scraper 84 does not rotate. Therefore, the connecting scraper 84 scrapes the iron powder off the adsorption plate 83 and onto the placement plate 82. The top of the placement plate 82 is located below the fixed tube 81, so the iron powder on the placement plate 82 is not easily affected by the lift and moves upward. Moreover, as the amount of iron powder increases, the fixed spring 85 contracts and the placement plate 82 moves downward, further preventing the iron powder from being carried away by the gas.

[0052] S4. When the rotating rod 63 rotates, the reciprocating lead screw 65 fixedly installed on the rotating rod 63 also rotates, causing the lead screw slider 66, which is mechanically engaged with the reciprocating lead screw 65, to move up and down. Under the action of the mounting rod 714, the adjusting plate 73 moves up and down accordingly, driving the fixed scraper 75 to move up and down as well. The up and down movement of the fixed scraper 75 prevents the magnesium powder from adhering to the fixed scraper 75 when scraping it. At the same time, as the lead screw slider 66 moves, it pushes the fixed block 68, causing the fixed block 68 to move upward and block the air outlet. When the airflow reaches the vicinity of the air outlet, it cannot continue to flow. Therefore, the magnesium powder is no longer lifted by the gas and falls down, making it easier for the magnesium powder to fall into the collection box 13. Then the lead screw slider 66 moves downward, and the fixed block 68 also moves downward under the action of the adjusting spring, returning to its original position.

[0053] In this invention, the magnesium block is first fed into the ball mill cylinder 3, then the motor 10 is started, and inert gas is simultaneously introduced into the ball mill cylinder 3. After the motor 10 starts, its output end drives the rotating rod 11 to rotate. Under the action of the belt drive assembly 12, the ball mill cylinder 3 rotates together with the rotating rod 11, causing the cast iron balls inside the ball mill cylinder 3 to rotate and ball mill the magnesium block, grinding it into nano-sized magnesium powder. At the same time, when the magnesium powder particles are ground to the nano-scale, the magnesium powder is blown towards the connecting pipe 4 by the flow of inert gas, and finally enters the fixed box 5 for collection. After the magnesium powder enters the fixed box 5, it first enters the inner side of the rotating cylinder 61 through the fixed pipe 81. The iron in the magnesium powder... The powder is attracted to the adsorption plate 83 and adsorbed onto the adsorption plate 83. The higher purity magnesium powder flows upward with the gas. During the gas flow, the gas impacts the impact fan blade 64, causing the impact fan blade 64 to rotate, which drives the rotating rod 63 to rotate as well. This causes the connecting bracket 62 and the rotating cylinder 61 to rotate as well. The rotation of the rotating cylinder 61 causes the gas to rotate as well. The rotation of the gas has a centrifugal effect, causing the magnesium powder to gather to the outside of the gas. This also facilitates the removal of iron powder. After the gas enters the inside of the collection tank 9, the magnesium powder, under centrifugal treatment, is close to the inner wall of the collection tank 9 and cannot move to the outside of the fixed box 5. The gas is then discharged from the gas outlet.

[0054] Simultaneously, as the rotating rod 63 rotates, the fixed cylinder 71 rotates accordingly, causing the fixed gear 74, which is fixedly sleeved on the outside of the fixed cylinder 71, to rotate as well. This causes the connecting gear 710, which meshes with the fixed gear 74, to rotate, resulting in the rotation of the connecting shaft 711. This, in turn, causes the connecting disc 712, which is fixedly mounted on the connecting shaft 711, to rotate. The connecting block 713, which is rotatably mounted on the connecting disc 712, moves in a circular motion along with the connecting disc 712. This causes the end of the adjusting rod 78 connected to the connecting block 713 to also move in a circular motion. Therefore, the adjusting rod 78 as a whole will rotate back and forth around the central shaft 79, causing the fixed scraper 75 mounted on the central shaft 79 to rotate back and forth accordingly, thus activating the return spring. The elasticity allows the fixed scraper 75 to remain pressed against the inner wall of the collection tank 9. The back-and-forth movement of the fixed scraper 75 scrapes the magnesium powder adhering to the inner wall of the collection tank 9 into the collection box 13 for collection. When the rotating cylinder 61 rotates, the adsorption plate 83 also rotates, while the connecting scraper 84 does not rotate. Therefore, the connecting scraper 84 scrapes the iron powder on the adsorption plate 83 and drops it onto the placement plate 82. The top of the placement plate 82 is located below the fixed tube 81, so the iron powder on the placement plate 82 is not easily affected by the lift and moves upward. Moreover, as the amount of iron powder increases, the fixed spring 85 contracts and the placement plate 82 moves downward, further preventing the iron powder from being carried away by the gas.

[0055] Furthermore, when the rotating rod 63 rotates, the reciprocating lead screw 65 fixedly installed on the rotating rod 63 also rotates, causing the lead screw slider 66, which is mechanically coupled with the reciprocating lead screw 65, to move up and down. Under the action of the mounting rod 714, the adjusting plate 73 moves up and down accordingly, driving the fixed scraper 75 to move up and down as well. The up and down movement of the fixed scraper 75 prevents the magnesium powder from adhering to the fixed scraper 75 when scraping it off. At the same time, as the lead screw slider 66 moves, it pushes the fixed block 68, causing the fixed block 68 to move upward and block the air outlet. When the airflow reaches the vicinity of the air outlet, it cannot continue to flow. Therefore, the magnesium powder is no longer lifted by the gas and falls down, making it easier for the magnesium powder to fall into the collection box 13. Then, the lead screw slider 66 moves downward, and the fixed block 68 also moves downward under the action of the adjusting spring, returning to its original position, and the gas is discharged.

7. The continuous nano-magnesium powder preparation equipment according to claim 6, characterized in that, The power structure includes a motor (10) fixedly mounted on a fixed base (1), and a rotating rod (11) is fixedly connected to the output end of the motor (10). The rotating rod (11) and the ball mill cylinder (3) are connected by a belt drive assembly (12).

8. A method for preparing continuous nano-magnesium powder according to claim 7, characterized in that, Includes the following steps: S1. Feed the magnesium block into the ball mill cylinder (3), start the motor (10), and simultaneously introduce inert gas into the ball mill cylinder (3). After the motor (10) starts, its output end drives the rotating rod (11) to rotate. Under the action of the belt drive assembly (12), the ball mill cylinder (3) rotates together with the rotating rod (11), allowing the cast iron ball inside the ball mill cylinder (3) to rotate and ball mill the magnesium block, grinding it into nano-sized magnesium powder. At the same time, when the magnesium powder particles are ground to the nano-sized, the magnesium powder will be blown to the connecting pipe (4) by the flow of inert gas and finally enter the fixed box (5) to collect the magnesium powder. S2. After the magnesium powder enters the fixed box (5), it first enters the inner side of the rotating cylinder (61) through the fixed tube (81). The iron powder in the magnesium powder will be attracted by the adsorption plate (83) and adsorbed on the adsorption plate (83). The magnesium powder with higher purity flows upward with the gas. During the gas flow, the gas will blow towards the impact fan blade (64), causing the impact fan blade (64) to rotate, driving the rotating rod (63) to rotate together, causing the connecting bracket (62) and the rotating cylinder (61) to rotate. The rotation of the rotating cylinder (61) will also cause the gas to rotate. The rotation of the gas can achieve a centrifugal effect, causing the magnesium powder to gather to the outside of the gas, which also facilitates the removal of iron powder. After the gas enters the inner side of the collection tank (9), the magnesium powder, under centrifugal treatment, is close to the inner wall of the collection tank (9) and cannot move to the outside of the fixed box (5). The gas is discharged from the outlet pipe. S3. During the rotation of the rotating rod (63), the fixed cylinder (71) rotates accordingly, causing the fixed gear (74) fixedly sleeved on the outside of the fixed cylinder (71) to rotate together, causing the connecting gear (710) meshing with the fixed gear (74) to rotate as well, causing the connecting shaft (711) to rotate, causing the connecting plate (712) fixedly mounted on the connecting shaft (711) to rotate, and the connecting block (713) rotatably mounted on the connecting plate (712) to move in a circle together with the connecting plate (712), causing the end of the adjusting rod (78) connected to the connecting block (713) to also move in a circle. Therefore, the adjusting rod (78) as a whole will rotate back and forth around the central shaft (79) as the axis, causing the fixed scraper (75) mounted on the central shaft (79) to rotate back and forth accordingly, resetting. The spring force allows the fixed scraper (75) to remain pressed against the inner wall of the collection tank (9). The back-and-forth movement of the fixed scraper (75) scrapes the magnesium powder adhering to the inner wall of the collection tank (9) into the collection box (13) for collection. When the rotating cylinder (61) rotates, the adsorption plate (83) also rotates, while the connecting scraper (84) does not rotate. Therefore, the connecting scraper (84) scrapes the iron powder off the adsorption plate (83) and onto the placement plate (82). The top of the placement plate (82) is located below the fixed tube (81), so the iron powder on the placement plate (82) is not easily affected by the lift force and moves upward. Moreover, as the amount of iron powder increases, the fixed spring (85) contracts and the placement plate (82) moves downward, further preventing the iron powder from being carried away by the gas. S4. When the rotating rod (63) rotates, the reciprocating lead screw (65) fixedly installed on the rotating rod (63) will also rotate, causing the lead screw slider (66) mechanically cooperating with the reciprocating lead screw (65) to move up and down. Under the action of the mounting rod (714), the adjusting plate (73) moves up and down accordingly, driving the fixed scraper (75) to move up and down accordingly. The up and down movement of the fixed scraper (75) prevents the magnesium powder from adhering to the fixed scraper (75) when scraping it off. At the same time, as the magnesium powder is removed, the sliding plate (66) moves up and down, the sliding plate (66) moves up and down, causing the sliding plate (66) to move ... As the lead screw slider (66) moves, it pushes the fixed block (68), causing the fixed block (68) to move upward and block the air outlet. When the airflow reaches the vicinity of the air outlet, it cannot continue to flow. Therefore, the magnesium powder is no longer lifted by the gas and falls, making it easier for the magnesium powder to fall into the collection box (13). Then, the lead screw slider (66) moves downward, and the fixed block (68) also moves downward under the action of the adjusting spring force, returning to its original position.
