Description

Technical Field

[0001] The present invention relates to the technical field of magnesium powder preparation, and in particular to a continuous preparation device and a preparation method of magnesium powder with high activity and stability. Background Art

[0002] Existing magnesium powder is generally prepared by electrolysis and atomization. During the solidification process of the atomized liquid magnesium, due to the limited size of the preparation tank, the fallen magnesium sometimes does not completely solidify, resulting in the problem of magnesium powder agglomeration. At the same time, the liquid magnesium sprayed by atomization may be doped with a small amount of chlorine. The chlorine continues to accumulate in the preparation tank and may eventually react with the liquid magnesium to produce magnesium chloride, resulting in impurities being doped in the magnesium powder, resulting in a decrease in its purity. In addition, the prepared magnesium powder is piled up together and needs to be screened multiple times to complete the classification of the magnesium powder. Summary of the Invention

[0010] Preferably, the fixed shaft extends to the inner wall of the extension tube and is fixedly connected to the fan blade, and the fan blade is fixedly connected to the inner wall of the extension tube.

[0011] A method for continuously preparing magnesium powder with high activity and stability comprises the following steps: S1. The molten raw material, i.e., anhydrous magnesium chloride, is fed into the electrolysis chamber and the temperature is controlled at 700 degrees Celsius. The molten metal magnesium is deposited at the cathode, while chlorine is deposited at the anode. An inert gas is introduced into the preparation tank, and the molten metal magnesium is sprayed into the inside of the preparation tank through a fixed hose and an atomizing nozzle. The magnesium powder is rapidly cooled into solid magnesium powder in the gas in the preparation tank, and the magnesium powder eventually falls onto a collecting plate. S2, start the motor, the output end of the motor drives the rotating rod to rotate, so that the rotating sleeve rod and the fixed shaft rotate together, drive the fixed sleeve rod and the fixed scraper to rotate, the rotation of the fixed scraper will cause the fixed cylinder to rotate accordingly, drive the gas inside the preparation tank to rotate together, and make the injected liquid magnesium rotate together, thereby achieving a centrifugal effect, so that liquid magnesium of different sizes can fall on different positions of the collecting plate, cooperate with the separation cylinder, so that magnesium powder of different specifications falls into the inner side of the separation cylinder with different specifications, and the rotation of the fixed scraper scrapes the magnesium powder on the collecting plate and collects it, and the inert gas enters the interior of the preparation tank from the air inlet pipe and is discharged from the exhaust pipe, thereby providing an upward lift for the falling droplets, prolonging the time the droplets stay in the air, and preventing the liquid magnesium falling on the collecting plate from being completely solidified, and the flow of the gas can replace the gas in the preparation tank, and take away the small amount of chlorine that enters the preparation tank along with the molten magnesium, to avoid the accumulation of chlorine on the inner side of the preparation tank, causing it to react with magnesium to produce magnesium chloride, which pollutes the magnesium powder; S3. When the fixed shaft rotates, the fan blades fixedly mounted on the fixed shaft rotate accordingly, accelerating the discharge of gas. At the same time, when the fixed shaft rotates, the extension tube rotates together, driving the fixed gear ring fixedly sleeved on the extension tube to rotate, causing the fixed gear meshing with the fixed gear ring to rotate, driving the transmission shaft and the rotating disk to rotate, and the rotating block connected to the rotating disk rotates accordingly, driving the transmission plate to rotate back and forth around the center of the mounting shaft, causing the fixed hose to swing back and forth, thereby causing the atomizing nozzle to swing back and forth, making the sprayed liquid magnesium more uniform; S4. As the rotating sleeve rotates, the fixed plate rotates together, driving the first extrusion block fixedly mounted on the fixed plate to rotate. When the first extrusion block rotates to the second extrusion block, it will squeeze the second extrusion block, thereby causing the first extrusion block and the fixed plate to move upward, and the fixed spring will deform, while pushing the rotating sleeve and the collecting plate to move upward together. After the first extrusion block is separated from the second extrusion block, the elastic force of the fixed spring causes the rotating sleeve to move downward, driving the first extrusion block and the fixed plate to move downward. When the collecting plate moves upward, it will push the air above the collecting plate to move upward, further accelerating the discharge of air and increasing the lift of the air on the liquid magnesium. When the collecting plate moves downward, the air will flow into the top of the collecting plate through the connecting port. S5. When the fixed plate moves upward, the connecting bracket will move accordingly, thereby pushing the telescopic rod to rotate upward with the connecting shaft as the axis, thereby pushing the piston plate to move upward, and its movement distance is greater than the movement distance of the fixed plate, so that the fixed piston extends into the inner side of the connecting port, blocking the connecting port, preventing air from flowing through the connecting port to the bottom of the collecting plate when the collecting plate moves upward. When the fixed plate moves downward, the fixed piston also moves downward, opening the connecting port to facilitate air to enter the top of the collecting plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. It can make the gas in the preparation tank rotate, thereby driving the liquid magnesium to rotate together, centrifuging the magnesium, so that magnesium droplets of different sizes are located at different positions when falling, thereby automatically grading the magnesium powder and collecting magnesium powder of different sizes into different separation cylinders, which is conducive to its subsequent processing; 2. Make the gas in the preparation tank flow upward, enter from the air inlet pipe and be discharged from the exhaust pipe, so as to discharge the chlorine gas flowing into the preparation tank, avoid the accumulation of chlorine gas in the preparation tank, and prevent the chlorine gas from reacting with the liquid magnesium, resulting in the appearance of magnesium chloride impurities in the magnesium powder. At the same time, the upward-flowing gas will generate an upward lift force on the liquid magnesium, thereby prolonging the time that the liquid magnesium stays in the air, so that it can be fully cooled and solidified, and avoiding the agglomeration of magnesium powder; 3. The collecting plate can be moved up and down. When the collecting plate moves upward, the fixed piston will block the connecting port. Therefore, the movement of the collecting plate will push the air upward, speeding up the gas discharge while also increasing the lift of the air on the droplets, further extending the cooling time. When the collecting plate moves downward, the fixed piston opens, so the air flows to the top of the collecting plate. BRIEF DESCRIPTION OF THE DRAWINGS

The inner wall of the preparation tank 2 is rotatably connected to a fixing ring 61, and a transmission structure 8 is installed on the fixing ring 61; The transmission structure 8 includes a telescopic rod 85, both ends of which can be telescoped to avoid motion interference. The fixing ring 61 and the piston plate 65 are fixedly connected to a connecting plate 81, and a connecting shaft 83 is rotatably connected between the connecting plates 81. A connecting cylinder 84 is fixedly sleeved on the connecting shaft 83, and the telescopic rod 85 is fixedly connected between the connecting cylinders 84. A connecting bracket 82 is rotatably installed on the telescopic rod 85, and the connecting bracket 82 is fixedly connected to the fixing plate 62. The telescopic rod 85 rotates around the connecting shaft 83 at the fixing ring 61. Therefore, when the fixed piston 66 moves upward or downward, the distance it moves is greater than the distance the fixed plate 62 moves. Therefore, when moving upward, the fixed piston 66 blocks the connecting port 17, and when moving downward, the connecting port 17 is opened; A one-way valve is fixedly mounted on the inner wall of the connecting port 17, and the one-way valve is flush with the top of the collecting plate 16. The one-way valve is a prior art one that allows gas to pass but prevents solids from passing. A mounting base 1 is fixedly mounted on the bottom end of the preparation tank 2, and an air inlet pipe 3 passes through the inner wall of the mounting base 1. The fixed shaft 15 extends to the inner wall of the extension tube and is fixedly connected to the fan blade 21, and the fan blade 21 is fixedly connected to the inner wall of the extension tube; A method for continuously preparing magnesium powder with high activity and stability comprises the following steps: S1. The molten raw material, i.e., anhydrous magnesium chloride, is fed into the electrolysis chamber and the temperature is controlled at 700 degrees Celsius. The molten metal magnesium is deposited at the cathode, while chlorine is deposited at the anode. An inert gas is introduced into the preparation tank 2, and the molten metal magnesium is sprayed into the inner side of the preparation tank 2 through the fixed hose 4 and the atomizing nozzle 12. The magnesium powder is rapidly cooled into solid magnesium powder in the gas in the preparation tank 2, and the magnesium powder eventually falls onto the collecting plate 16. S2, start the motor 13, the output end of the motor 13 drives the rotating rod 19 to rotate, so that the rotating sleeve rod 18 and the fixed shaft 15 rotate together, driving the fixed sleeve rod 14 and the fixed scraper 10 to rotate, the rotation of the fixed scraper 10 will cause the fixed cylinder 9 to rotate accordingly, driving the gas inside the preparation tank 2 to rotate together, and causing the injected liquid magnesium to rotate together, thereby achieving a centrifugal effect, so that liquid magnesium of different sizes can fall to different positions on the collecting plate 16, and cooperate with the separating cylinder 11, so that magnesium powder of different specifications falls into the inner side of the separating cylinder 11 with different specifications, and the rotation of the fixed scraper 10 The magnesium powder on the collecting plate 16 is scraped up and collected, and the inert gas enters the interior of the preparation tank 2 from the air inlet pipe 3 and is discharged from the exhaust pipe 5, thereby providing an upward lift for the falling droplets, prolonging the time the droplets stay in the air, and preventing the liquid magnesium that falls on the collecting plate 16 from not completely solidifying. In addition, the flow of the gas can replace the gas in the preparation tank 2, and take away the small amount of chlorine that enters the preparation tank 2 along with the molten magnesium, thereby preventing the chlorine from accumulating inside the preparation tank 2, causing it to react with magnesium to produce magnesium chloride and pollute the magnesium powder; S3. When the fixed shaft 15 rotates, the fan blade 21 fixedly mounted on the fixed shaft 15 rotates accordingly, accelerating the discharge of gas. At the same time, when the fixed shaft 15 rotates, the extension tube rotates together, driving the fixed gear ring 71 fixedly sleeved on the extension tube to rotate, causing the fixed gear 74 meshing with the fixed gear ring 71 to rotate, driving the transmission shaft 73 and the rotating disk 75 to rotate, and the rotating block 76 connected to the rotating disk 75 to rotate accordingly, driving the transmission plate 72 to rotate back and forth about the center of the mounting axis, causing the fixed hose 4 to swing back and forth, thereby causing the atomizing nozzle 12 to swing back and forth, making the sprayed liquid magnesium more uniform; S4. As the rotating sleeve rod 18 rotates, the fixed plate 62 rotates together, driving the first extrusion block 63 fixedly installed on the fixed plate 62 to rotate. When the first extrusion block 63 rotates to the second extrusion block 64, it will squeeze the second extrusion block 64, so that the first extrusion block 63 and the fixed plate 62 move upward, and the fixed spring 20 is deformed, and at the same time, it pushes the rotating sleeve rod 18 and the collecting plate 16 to move upward together. After the first extrusion block 63 is separated from the second extrusion block 64, the elastic force of the fixed spring 20 causes the rotating sleeve rod 18 to move downward, driving the first extrusion block 63 and the fixed plate 62 to move downward. When the collecting plate 16 moves upward, it pushes the air above the collecting plate 16 to move upward, further accelerating the discharge of air and increasing the lift of the air on the liquid magnesium. When the collecting plate 16 moves downward, the air will flow into the top of the collecting plate 16 through the connecting port 17; S5. When the fixed plate 62 moves upward, the connecting bracket 82 will move accordingly, thereby pushing the telescopic rod 85 to rotate upward with the connecting shaft 83 as the axis, thereby pushing the piston plate 65 to move upward, and its movement distance is greater than the movement distance of the fixed plate 62, so that the fixed piston 66 extends into the inner side of the connecting port 17, blocking the connecting port 17, preventing the air from passing through the connecting port 17 and flowing to the bottom of the collecting plate 16 when the collecting plate 16 moves upward. When the fixed plate 62 moves downward, the fixed piston 66 also moves downward, opening the connecting port 17 to facilitate air to enter the top of the collecting plate 16.

[0016] In the present invention, the molten raw material, i.e., anhydrous magnesium chloride, is first fed into the electrolysis chamber and the temperature is controlled at 700 degrees Celsius. The molten metal magnesium is deposited at the cathode, while chlorine is deposited at the anode. An inert gas is introduced into the preparation tank 2, and the molten metal magnesium is sprayed into the inside of the preparation tank 2 through the fixed hose 4 and the atomizing nozzle 12. The magnesium powder is rapidly cooled into solid magnesium powder in the gas in the preparation tank 2, and the magnesium powder eventually falls onto the collection plate 16. At the same time, the motor 13 is started, and the output end of the motor 13 drives the rotating rod 19 to rotate, so that the rotating sleeve rod 18 and the fixed shaft 15 rotate together, and the fixed sleeve rod 14 and the fixed scraper 10 rotate. The rotation of the fixed scraper 10 will cause the fixed cylinder 9 to rotate accordingly, and drive the gas inside the preparation tank 2 to rotate together, so that the injected liquid magnesium rotates together, thereby achieving a centrifugal effect, so that liquid magnesium of different sizes can fall to different positions on the collecting plate 16, and cooperate with the separating cylinder 11 to make magnesium powder of different specifications fall into the inner side of the separating cylinder 11 with different specifications, and the rotation of the fixed scraper 10 The magnesium powder on the collecting plate 16 is scraped up and collected, and the inert gas enters the interior of the preparation tank 2 from the air inlet pipe 3 and is discharged from the exhaust pipe 5, thereby providing an upward lift for the falling droplets, prolonging the time the droplets stay in the air, and preventing the liquid magnesium that falls on the collecting plate 16 from not completely solidifying. In addition, the flow of the gas can replace the gas in the preparation tank 2, and take away the small amount of chlorine that enters the preparation tank 2 along with the molten magnesium, thereby preventing the chlorine from accumulating inside the preparation tank 2, causing it to react with magnesium to produce magnesium chloride and pollute the magnesium powder; Moreover, as the rotating sleeve rod 18 rotates, the fixed plate 62 rotates together, driving the first extrusion block 63 fixedly installed on the fixed plate 62 to rotate. When the first extrusion block 63 rotates to the second extrusion block 64, it will squeeze each other with the second extrusion block 64, so that the first extrusion block 63 and the fixed plate 62 move upward, and the fixed spring 20 is deformed. At the same time, it pushes the rotating sleeve rod 18 and the collecting plate 16 to move upward together. After the first extrusion block 63 is separated from the second extrusion block 64, the elastic force of the fixed spring 20 causes the rotating sleeve rod 18 to move downward, driving the first extrusion block 63 and the fixed plate 62 to move downward, causing the collecting plate 16 to move up and down. The downward movement of the collecting plate 16 will cause air to flow into the top of the collecting plate 16 through the connecting port 17. When the fixed plate 62 moves upward, the connecting bracket 82 moves accordingly, thereby pushing the telescopic rod 85 to rotate upward about the connecting shaft 83 as the axis, thereby pushing the piston plate 65 to move upward, and the distance it moves is greater than the distance moved by the fixed plate 62, so that the fixed piston 66 extends into the inner side of the connecting port 17, blocking the connecting port 17, and preventing the air from flowing through the connecting port 17 to the bottom of the collecting plate 16 when the collecting plate 16 moves upward. The movement of the collecting plate 16 pushes the air above the collecting plate 16 to move upward, further accelerating the discharge of air and increasing the lift of the air on the liquid magnesium. When the fixed plate 62 moves downward, the fixed piston 66 also moves downward, opening the connecting port 17, so that the air can enter the top of the collecting plate 16. In addition, when the fixed shaft 15 rotates, the fan blades 21 fixedly mounted on the fixed shaft 15 rotate accordingly, accelerating the discharge of gas. At the same time, when the fixed shaft 15 rotates, the extension tube rotates together, driving the fixed gear ring 71 fixedly mounted on the extension tube to rotate, and the fixed gear 74 engaged with the fixed gear ring 71 rotates, driving the transmission shaft 73 and the rotating disk 75 to rotate, and the rotating block 76 connected to the rotating disk 75 rotates accordingly, driving the transmission plate 72 to rotate back and forth about the center of the mounting axis, causing the fixed hose 4 to swing back and forth, thereby causing the atomizing nozzle 12 to swing back and forth, making the injected liquid magnesium more uniform.

The molten metal magnesium is sprayed into the inner side of the preparation tank (2) through a fixed hose (4) and an atomizing nozzle (12). The magnesium powder is rapidly cooled into solid magnesium powder in the gas in the preparation tank (2), and the magnesium powder finally falls onto a collecting plate (16). S2. Start the motor (13). The output end of the motor (13) drives the rotating rod (19) to rotate, so that the rotating sleeve rod (18) and the fixed shaft (15) rotate together, driving the fixed sleeve rod (14) and the fixed scraper (10) to rotate. The rotation of the fixed scraper (10) causes the fixed cylinder (9) to rotate accordingly, driving the gas inside the preparation tank (2) to rotate together, causing the injected liquid magnesium to rotate together, thereby achieving a centrifugal effect, so that liquid magnesium of different sizes can fall to different positions on the collecting plate (16), and cooperate with the separation cylinder (11) to make magnesium powder of different specifications fall into the inner side of the separation cylinder (11) with different sizes, while the fixed scraper The rotation of (10) scrapes the magnesium powder on the collecting plate (16) and collects it, and the inert gas enters the interior of the preparation tank (2) from the air inlet pipe (3) and is discharged from the exhaust pipe (5), thereby providing an upward lift for the falling droplets, prolonging the time the droplets stay in the air, and preventing the liquid magnesium that falls on the collecting plate (16) from being completely solidified. In addition, the flow of the gas can replace the gas in the preparation tank (2), and take away a small amount of chlorine that enters the preparation tank (2) along with the molten magnesium, thereby preventing the chlorine from accumulating on the inside of the preparation tank (2), causing it to react with magnesium to produce magnesium chloride and pollute the magnesium powder; S3. When the fixed shaft (15) rotates, the fan blade (21) fixedly mounted on the fixed shaft (15) rotates accordingly, accelerating the discharge of gas. At the same time, the rotation of the fixed shaft (15) causes the extension tube to rotate together, driving the fixed gear ring (71) fixedly sleeved on the extension tube to rotate, causing the fixed gear (74) meshed with the fixed gear ring (71) to rotate, driving the transmission shaft (73) and the rotating disk (75) to rotate, and the rotating block (76) connected to the rotating disk (75) to rotate accordingly, driving the transmission plate (72) to rotate back and forth around the center of the mounting axis, causing the fixed hose (4) to swing back and forth, thereby causing the atomizing nozzle (12) to swing back and forth, so that the liquid magnesium sprayed in is more uniform; S4. As the rotating sleeve (18) rotates, the fixed plate (62) rotates together, driving the first extrusion block (63) fixedly mounted on the fixed plate (62) to rotate. When the first extrusion block (63) rotates to the second extrusion block (64), it will squeeze the second extrusion block (64) against each other, so that the first extrusion block (63) and the fixed plate (62) move upward, the fixed spring (20) deforms, and at the same time pushes the rotating sleeve (18) and the collecting plate (16) to move upward together. After the first extrusion block (63) and the second extrusion block (64) are separated, the elastic force of the fixed spring (20) causes the rotating sleeve (18) to move downward, driving the first extrusion block (63) and the fixed plate (62) to move downward. When the collecting plate (16) moves upward, it pushes the air above the collecting plate (16) to move upward, further accelerating the discharge of air and increasing the lift of the air on the liquid magnesium. When the collecting plate (16) moves downward, the air flows into the top of the collecting plate (16) through the connecting port (17); S5. When the fixed plate (62) moves upward, the connecting bracket (82) moves accordingly, thereby pushing the telescopic rod (85) to rotate upward with the connecting shaft (83) as the axis, thereby pushing the piston plate (65) to move upward, and the distance of its movement is greater than the distance of movement of the fixed plate (62), so that the fixed piston (66) extends into the inner side of the connecting port (17), blocking the connecting port (17) to prevent the air from flowing through the connecting port (17) to the bottom of the collecting plate (16) when the collecting plate (16) moves upward. When the fixed plate (62) moves downward, the fixed piston (66) also moves downward, opening the connecting port (17) to facilitate the air to enter the top of the collecting plate (16).
