Description

Technical Field

[0001] This invention relates to the field of magnesium powder preparation technology, and in particular to a continuous magnesium powder preparation equipment and preparation method with high activity and stability. Background Technology

[0002] Existing magnesium powder is generally prepared by electrolysis and atomization. During the solidification process of atomized liquid magnesium, due to the limited size of the preparation tank, sometimes the falling magnesium does not completely solidify, leading to agglomeration of the magnesium powder. At the same time, the atomized liquid magnesium may contain a small amount of chlorine gas. As the chlorine gas accumulates in the preparation tank, it may eventually react with the liquid magnesium to produce magnesium chloride, resulting in impurities in the magnesium powder and a decrease in its purity. In addition, the prepared magnesium powder piles up together and needs to be sieved multiple times to complete the grading of the magnesium powder. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology by proposing a continuous magnesium powder preparation equipment and method with high activity and stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a continuous magnesium powder preparation device and preparation method with high activity and stability, comprising:

[0005] A preparation tank, on which a fixed hose is fixedly installed, the fixed hose extends to the inner wall of the preparation tank and is fixedly connected to an atomizing nozzle, and a collection plate is slidably connected to the inner wall of the preparation tank, the collection plate having a connection port;

[0006] A uniform spraying structure includes an exhaust pipe fixedly connected to a preparation tank, an extension pipe rotatably mounted on the exhaust pipe extending into the inner side of the preparation tank, an air inlet pipe fixedly connected to the preparation tank, a fixed toothed ring fixedly sleeved on the side wall of the extension pipe, a drive shaft rotatably connected to the inner wall of the preparation tank, a fixed gear fixedly sleeved on the drive shaft and meshing with the fixed toothed ring, a rotating disk fixedly connected to the drive shaft, a rotating block rotatably connected to the rotating disk, a drive plate rotatably connected to the rotating block, and the drive plate sleeved on a corresponding fixed hose, and a power structure installed on the preparation tank.

[0007] Preferably, the power structure includes a motor fixedly mounted on the preparation tank, a rotating rod fixedly connected to the output end of the motor, the rotating rod extending to the inside of the preparation tank and slidably sleeved with a rotating sleeve rod, a fixed shaft rotatably connected to the collection plate, the fixed shaft passing through the collection plate and fixedly connected to the rotating sleeve rod, a fixed sleeve rod fixedly sleeved on the fixed shaft, a fixed scraper fixedly connected to the fixed sleeve rod, a fixed cylinder rotatably connected to the collection plate and fixedly connected to the fixed scraper, and a separator cylinder fixedly connected to the fixed scraper.

[0008] Preferably, the preparation tank is equipped with a lifting structure, which includes a second extrusion block fixedly connected to the inner side of the preparation tank. A fixed plate is fixedly sleeved on the rotating sleeve rod. A first extrusion block corresponding to the second extrusion block is fixedly connected to the fixed plate. A fixed spring is fixedly connected between the fixed plate and the inner wall of the preparation tank. A connecting rod is fixedly connected to the fixed plate. A connecting sleeve rod is slidably sleeved on the connecting rod. A piston plate is fixedly connected to the connecting sleeve rod. A fixed piston matching the connecting port is fixedly connected to the piston plate. A fixed ring is rotatably connected to the inner wall of the preparation tank. A transmission structure is installed on the fixed ring.

[0009] Preferably, the transmission structure includes a telescopic rod, a connecting plate is fixedly connected to both the fixed ring and the piston plate, a connecting shaft is rotatably connected between the connecting plates, a connecting cylinder is fixedly sleeved on the connecting shaft, the telescopic rod is fixedly connected between the connecting cylinders, a connecting bracket is rotatably mounted on the telescopic rod, and the connecting bracket is fixedly connected to the fixed plate.

[0010] Preferably, a one-way valve is fixedly installed on the inner wall of the connection port, and the one-way valve is flush with the top of the collecting plate.

[0011] Preferably, a mounting base is fixedly installed at the bottom of the preparation tank, and the air inlet pipe penetrates the inner wall of the mounting base.

[0012] Preferably, the fixed shaft extends to the inner wall of the extension tube and is fixedly connected to a fan blade, and the fan blade is fixedly connected to the inner wall of the extension tube.

[0013] A continuous method for preparing magnesium powder with high activity and stability includes the following steps: S1, molten raw material, namely anhydrous magnesium chloride, is fed into an electrolysis chamber and the temperature is controlled at 700 degrees Celsius. Molten metallic magnesium is precipitated at the cathode, while chlorine gas is precipitated at the anode. Inert gas is introduced into the preparation tank, and molten metallic 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 inside the preparation tank and finally falls onto a collection plate.

[0014] S2. Start the motor. The motor's output drives the rotating rod to rotate, causing the rotating sleeve rod and the fixed shaft to rotate together. This, in turn, causes the fixed sleeve rod and the fixed scraper to rotate. The rotation of the fixed scraper causes the fixed cylinder to rotate as well, causing the gas inside the preparation tank to rotate. This causes the injected liquid magnesium to rotate as well, thus achieving a centrifugal effect. This allows liquid magnesium of different sizes to fall to different positions on the collection plate. In conjunction with the separator, magnesium powder of different specifications falls into the inner side of the separator with different separators. The rotation of the fixed scraper scrapes up the magnesium powder on the collection plate and collects it. Inert gas enters the preparation tank from the inlet pipe and exits from the exhaust pipe, thus providing upward lift to the falling droplets, prolonging the time the droplets stay in the air, and preventing the liquid magnesium falling onto the collection plate from not completely solidifying. Moreover, the gas flow can replace the gas inside the preparation tank, carrying away the small amount of chlorine gas that enters the preparation tank with the molten magnesium. This prevents chlorine gas from accumulating inside the preparation tank and reacting with magnesium to produce magnesium chloride, which would contaminate the magnesium powder.

[0015] S3. When the fixed shaft rotates, the fan blades fixedly installed on the fixed shaft rotate accordingly, accelerating the gas discharge. At the same time, the extension tube rotates together with the fixed shaft, 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. The rotating block rotatably connected to the rotating disk rotates accordingly, driving the transmission plate to rotate back and forth, causing the fixed hose to swing back and forth, thus causing the atomizing nozzle to swing back and forth as well, making the sprayed liquid magnesium more uniform.

[0016] S4. As the rotating sleeve rotates, the fixed plate rotates together, causing the first pressing block fixedly mounted on the fixed plate to rotate. When the first pressing block rotates to the second pressing block, it will press against the second pressing block, thereby causing the first pressing block and the fixed plate to move upward. The fixed spring deforms and pushes the rotating sleeve and the collecting plate to move upward together. After the first pressing block and the second pressing block separate, the elastic force of the fixed spring causes the rotating sleeve to move downward, causing the first pressing block and the fixed plate to move downward. When the collecting plate moves upward, it will push the air above the collecting plate upward, further accelerating the air discharge and increasing the lift force of the air on the liquid magnesium. When the collecting plate moves downward, it will cause the air to flow into the upper part of the collecting plate through the connecting port.

[0017] S5. When the fixed plate moves upward, the connecting bracket moves accordingly, thereby pushing the telescopic rod to rotate upward around the connecting shaft, which in turn pushes the piston plate upward. The distance it moves is greater than the distance the fixed plate moves, causing the fixed piston to extend into the inside of the connecting port and block the connecting port. This prevents air from flowing through the connecting port to the bottom of the collecting plate when it moves upward. When the fixed plate moves downward, the fixed piston also moves downward, opening the connecting port so that air can enter the top of the collecting plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 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 classifying the magnesium powder, collecting magnesium powder of different sizes into different separators, which is beneficial for subsequent processing.

[0019] 2. The gas inside the preparation tank flows upward, entering through the inlet pipe and exiting through the outlet pipe, thereby expelling the chlorine gas flowing into the preparation tank and preventing its accumulation. This prevents the chlorine gas from reacting with the liquid magnesium, which could lead to 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, thus prolonging the time the liquid magnesium spends in the air, allowing it to cool and solidify sufficiently and preventing the magnesium powder from clumping.

[0020] 3. It can move the collecting plate up and down. When the collecting plate moves upward, the fixed piston will block the connection port. Therefore, the movement of the collecting plate will push the air upward, which will accelerate the gas discharge and increase the lift of the air on the droplets, further prolonging the cooling time. When the collecting plate moves downward, the fixed piston will open, so the air will flow to the top of the collecting plate. Attached Figure Description

[0029] Reference Figure 1 Figure 8 A continuous magnesium powder preparation device with high activity and stability includes: a preparation tank 2, an inert gas, such as helium, is introduced into the preparation tank 2, a fixed hose 4 is fixedly installed on the preparation tank 2, the fixed hose 4 can rotate, thereby driving the atomizing nozzle 12 to rotate, the fixed hose 4 extends to the inner wall of the preparation tank 2 and is fixedly connected to the atomizing nozzle 12, and a collection plate 16 is slidably connected to the inner wall of the preparation tank 2, and a connection port 17 is opened on the collection plate 16;

[0030] The uniform spraying structure 7 includes an exhaust pipe 5 fixedly connected to the preparation tank 2, an extension pipe rotatably mounted on the exhaust pipe 5 and extending to the inside of the preparation tank 2, an air inlet pipe 3 fixedly connected to the preparation tank 2, a fixed toothed ring 71 fixedly sleeved on the side wall of the extension pipe, a drive shaft 73 rotatably connected to the inner wall of the preparation tank 2, a fixed gear 74 fixedly sleeved on the drive shaft 73 and meshing with the fixed toothed ring 71, a rotating disk 75 fixedly connected to the drive shaft 73, a rotating block 76 rotatably connected to the rotating disk 75, a drive plate 72 rotatably connected to the rotating block 76 and sleeved on the corresponding fixed hose 4, and a power structure installed on the preparation tank 2.

[0031] The power structure includes a motor 13 fixedly mounted on the preparation tank 2. A rotating rod 19 is fixedly connected to the output end of the motor 13. The rotating rod 19 extends into the inner side of the preparation tank 2 and is slidably sleeved with a rotating sleeve rod 18. A fixed shaft 15 is rotatably connected to the collection plate 16, and the fixed shaft 15 passes through the collection plate 16 and is fixedly connected to the rotating sleeve rod 18. A fixed sleeve rod 14 is fixedly sleeved on the fixed shaft 15. A fixed scraper 10 is fixedly connected to the fixed sleeve rod 14. A fixed cylinder 9 is rotatably connected to the collection plate 16 and fixedly connected to the fixed scraper 10. A separator cylinder 11 is fixedly connected to the fixed scraper 10. The magnesium powder is centrifuged by the rotation of the air, so that magnesium powder of different sizes falls at different positions and falls into different separator cylinders 11 for automatic screening. At the same time, the rotation of the fixed scraper 10 scrapes the collected magnesium powder together for subsequent processing.

[0032] The preparation tank 2 is equipped with a lifting structure 6. The lifting structure 6 includes a second extrusion block 64 fixedly connected to the inner side of the preparation tank 2. A fixed plate 62 is fixedly sleeved on the rotating sleeve rod 18. A first extrusion block 63 corresponding to the second extrusion block 64 is fixedly connected on the fixed plate 62. A fixed spring 20 is fixedly connected between the fixed plate 62 and the inner wall of the preparation tank 2. A connecting rod 67 is fixedly connected on the fixed plate 62. A connecting sleeve rod 68 is slidably sleeved on the connecting rod 67. A piston plate 65 is fixedly connected on the connecting sleeve rod 68. A fixed piston 66 matching the connecting port 17 is fixedly connected on the piston plate 65. A fixed ring 61 is rotatably connected to the inner wall of the preparation tank 2. A transmission structure 8 is installed on the fixed ring 61.

[0033] The transmission structure 8 includes a telescopic rod 85, both ends of which can extend and retract to avoid motion interference. A connecting plate 81 is fixedly connected to both the fixed ring 61 and the piston plate 65. A connecting shaft 83 is rotatably connected between the connecting plates 81. A connecting sleeve 84 is fixedly sleeved on the connecting shaft 83, and the telescopic rod 85 is fixedly connected between the connecting sleeves 84. A connecting bracket 82 is rotatably mounted on the telescopic rod 85, and the connecting bracket 82 is fixedly connected to the fixed plate 62. The telescopic rod 85 will rotate around the connecting shaft 83 at the fixed ring 61 as the axis. 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 it moves upward, the fixed piston 66 will block the connecting port 17, and when it moves downward, it will open the connecting port 17.

[0034] A one-way valve is fixedly installed 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 existing technology and can allow gas to pass through while solids cannot. A mounting base 1 is fixedly installed at the bottom of the preparation tank 2, and the 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 pipe and is fixedly connected to the fan blade 21, and the fan blade 21 is fixedly connected to the inner wall of the extension pipe.

[0035] A continuous method for preparing magnesium powder with high activity and stability includes the following steps:

[0036] S1. Molten raw material, namely anhydrous magnesium chloride, is fed into the electrolysis chamber and the temperature is controlled at 700 degrees Celsius. Molten metallic magnesium is precipitated at the cathode, while chlorine gas is precipitated at the anode. Inert gas is introduced into the preparation tank 2. Molten metallic magnesium is sprayed into the inside of the preparation tank 2 through the fixed hose 4 and the atomizing nozzle 12. It is rapidly cooled into solid magnesium powder in the gas in the preparation tank 2. The magnesium powder eventually falls onto the collection plate 16.

[0037] S2. Start motor 13. The output of motor 13 drives the rotating rod 19 to rotate, causing the rotating sleeve rod 18 and the fixed shaft 15 to rotate together. This causes 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 as well, causing the gas inside the preparation tank 2 to rotate together. This causes the injected liquid magnesium to rotate together, thus achieving a centrifugal effect. This allows liquid magnesium of different sizes to fall to different positions on the collection plate 16. In conjunction with the separator 11, magnesium powder of different specifications falls into the inner side of the separator 11 with different separators. The rotation of the fixed scraper 10... The process scrapes up the magnesium powder on the collection plate 16 and collects it. Inert gas enters the preparation tank 2 from the inlet pipe 3 and exits from the exhaust pipe 5, thus providing upward lift to the falling droplets, prolonging the time the droplets stay in the air, and preventing the liquid magnesium falling on the collection plate 16 from not completely solidifying. Moreover, the flow of gas can replace the gas in the preparation tank 2, carrying away the small amount of chlorine gas that enters the preparation tank 2 along with the molten magnesium, preventing chlorine gas from accumulating on the inside of the preparation tank 2, causing it to react with magnesium to produce magnesium chloride and contaminate the magnesium powder.

[0038] S3. When the fixed shaft 15 rotates, the fan blade 21 fixedly installed 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. The rotating block 76 rotatably connected to the rotating disk 75 rotates accordingly, driving the transmission plate 72 to rotate back and forth, causing the fixed hose 4 to swing back and forth, thereby causing the atomizing nozzle 12 to swing back and forth as well, making the sprayed liquid magnesium more uniform.

[0039] S4. As the rotating sleeve rod 18 rotates, the fixed plate 62 rotates together, causing the first pressing block 63 fixedly installed on the fixed plate 62 to rotate. When the first pressing block 63 rotates to the second pressing block 64, it will press against the second pressing block 64, thereby causing the first pressing block 63 and the fixed plate 62 to move upward. The fixed spring 20 deforms and pushes the rotating sleeve rod 18 and the collecting plate 16 to move upward together. After the first pressing block 63 and the second pressing block 64 separate, the elastic force of the fixed spring 20 causes the rotating sleeve rod 18 to move downward, causing the first pressing block 63 and the fixed plate 62 to move downward. When the collecting plate 16 moves upward, it will push the air above the collecting plate 16 to move upward, further accelerating the air discharge and increasing the lift force of the air on the liquid magnesium. When the collecting plate 16 moves downward, it will cause the air to flow into the upper part of the collecting plate 16 through the connecting port 17.

[0040] S5. When the fixed plate 62 moves upward, the connecting bracket 82 moves accordingly, thereby pushing the telescopic rod 85 to rotate upward around 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 the fixed plate 62 moves, so that the fixed piston 66 extends into the inside of the connecting port 17 and blocks the connecting port 17, preventing 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 so that air can enter the top of the collecting plate 16.

[0041] In this invention, molten raw material, namely anhydrous magnesium chloride, is first fed into the electrolysis chamber and the temperature is controlled at 700 degrees Celsius. Molten metallic magnesium is precipitated at the cathode, while chlorine gas is precipitated at the anode. Inert gas is introduced into the preparation tank 2, and molten metallic magnesium is sprayed into the inside of the preparation tank 2 through the fixed hose 4 and the atomizing nozzle 12. It is rapidly cooled into solid magnesium powder in the gas in the preparation tank 2, and the magnesium powder finally falls onto the collection plate 16.

[0042] Simultaneously, motor 13 is started. The output end of motor 13 drives the rotating rod 19 to rotate, causing the rotating sleeve rod 18 and the fixed shaft 15 to rotate together. This, in turn, drives 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 as well, causing the gas inside the preparation tank 2 to rotate together. This causes the injected liquid magnesium to rotate as well, thus achieving a centrifugal effect. This allows liquid magnesium of different sizes to fall to different positions on the collection plate 16. In conjunction with the separator cylinder 11, magnesium powder of different specifications falls into the inner side of the separator cylinder 11 with different separators. The rotation of the fixed scraper 10... The process scrapes up the magnesium powder on the collection plate 16 and collects it. Inert gas enters the preparation tank 2 from the inlet pipe 3 and exits from the exhaust pipe 5, thus providing upward lift to the falling droplets, prolonging the time the droplets stay in the air, and preventing the liquid magnesium falling on the collection plate 16 from not completely solidifying. Moreover, the flow of gas can replace the gas in the preparation tank 2, carrying away the small amount of chlorine gas that enters the preparation tank 2 along with the molten magnesium, preventing chlorine gas from accumulating on the inside of the preparation tank 2, causing it to react with magnesium to produce magnesium chloride and contaminate the magnesium powder.

[0043] Furthermore, as the rotating sleeve 18 rotates, the fixed plate 62 rotates together, causing the first pressing block 63, which is fixedly mounted on the fixed plate 62, to rotate. When the first pressing block 63 rotates to the position of the second pressing block 64, it will press against the second pressing block 64, thereby causing the first pressing block 63 and the fixed plate 62 to move upward. The fixing spring 20 deforms, which in turn pushes the rotating sleeve 18 and the collecting plate 16 to move upward together. After the first pressing block 63 separates from the second pressing block 64, the elastic force of the fixing spring 20 causes the rotating sleeve 18 to move downward, causing the first pressing 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 upper part 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 around the connecting shaft 83, which in turn pushes the piston plate 65 to move upward. The distance it moves is greater than the distance the fixed plate 62 moves, causing the fixed piston 66 to extend into the inside of the connecting port 17 and block the connecting port 17. This prevents 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 will push the air above the collecting plate 16 upward, further accelerating the exhaust of air and increasing the lift force 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 air can enter the area above the collecting plate 16.

[0044] In addition, when the fixed shaft 15 rotates, the fan blades 21 fixedly installed on the fixed shaft 15 rotate accordingly, accelerating the exhaust 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. The rotating block 76 rotatably connected to the rotating disk 75 rotates accordingly, driving the transmission plate 72 to rotate back and forth, causing the fixed hose 4 to swing back and forth, thereby causing the atomizing nozzle 12 to swing back and forth as well, making the injected liquid magnesium more uniform.

The output end of the motor (13) drives the rotating rod (19) to rotate, causing the rotating sleeve rod (18) and the fixed shaft (15) to rotate together, which in turn drives 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 as well, causing 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 collection plate (16). With the help of the separator (11), magnesium powder of different specifications falls into the inner side of the separator (11) with different sizes, while the fixed scraper The rotation of (10) scrapes up the magnesium powder on the collecting plate (16) and collects it. Inert gas enters the interior of the preparation tank (2) from the inlet pipe (3) and is discharged from the exhaust pipe (5), thereby providing upward lift to the falling droplets, prolonging the time the droplets stay in the air, and preventing the liquid magnesium falling on the collecting plate (16) from not completely solidifying. Moreover, the flow of gas can replace the gas in the preparation tank (2), and carry away the small amount of chlorine gas that enters the preparation tank (2) along with the molten magnesium, preventing chlorine gas from accumulating on the inside of the preparation tank (2) and causing it to react with magnesium to produce magnesium chloride, which would contaminate the magnesium powder. S3. When the fixed shaft (15) rotates, the fan blade (21) fixedly installed 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) meshing with the fixed gear ring (71) to rotate, driving the transmission shaft (73) and the rotating disk (75) to rotate. The rotating block (76) rotatably connected to the rotating disk (75) rotates accordingly, driving the transmission plate (72) to rotate back and forth, causing the fixed hose (4) to swing back and forth, thus causing the atomizing nozzle (12) to swing back and forth as well, making the injected liquid magnesium more uniform. S4. As the rotating sleeve (18) rotates, the fixed plate (62) rotates together, causing the first pressing block (63) fixedly installed on the fixed plate (62) to rotate. When the first pressing block (63) rotates to the second pressing block (64), it will press against the second pressing block (64), thereby causing the first pressing block (63) and the fixed plate (62) to move upward. The fixed spring (20) deforms and pushes the rotating sleeve (18) and the collecting plate (16) to move upward together. After the first pressing block (63) and the second pressing block (64) separate, the elastic force of the fixed spring (20) causes the rotating sleeve (18) to move downward, causing the first pressing block (63) and the fixed plate (62) to move downward. When the collecting plate (16) moves upward, it will push the air above the collecting plate (16) to move upward, further accelerating the air discharge and increasing the lift force of the air on the liquid magnesium. When the collecting plate (16) moves downward, it will cause the air to flow into the upper part 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 around 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 the fixed plate (62) moves, so that the fixed piston (66) extends into the inside of the connecting port (17) and blocks the connecting port (17) to prevent 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) so that air can enter the top of the collecting plate (16).
