Description

Technical Field

[0001] The invention relates to the technical field of sendustine aluminum powder production, and in particular to sendustine aluminum powder production equipment based on a gas atomization powder making process. Background Art

[0002] Gas atomization powder making refers to the use of high-speed airflow to break up liquid metal into small droplets, which are then quickly cooled and solidified to form powder, thereby achieving efficient preparation of metal powder. The metal powder prepared by gas atomization has the advantages of fine particle size, high sphericity, high purity, low oxygen content and fast forming speed.

[0003] However, in the traditional gas atomization powder making process, a non-restricted atomizing nozzle is usually used. When this nozzle is used, the metal solution will fall along the direction of gravity before being atomized, and the atomizing nozzle is far away from the metal solution, which will cause energy loss and make the obtained metal powder coarse. When a restricted atomizing nozzle is used, the action distance between the gas and the melt can be greatly shortened, the kinetic energy loss of the gas is reduced, and a finer powder can be obtained. However, the design of this nozzle is relatively complicated and it is easy to cause the air jet to be blocked, which will lead to uneven atomization effect, uneven powder particle size, and affect the powder making efficiency.

[0017] 1. The present invention indirectly drives the tray to rotate when the motor rotates, and the metal solution is stretched into sheets and flies out under the action of centrifugal force. At this time, the tray also drives the metal liquid to move upward, so that the metal liquid on the tray is closer to the gas collecting ring, so that the high-speed airflow can more effectively impact the metal liquid and break it into smaller and more uniform droplets. When the distance from the gas collecting ring is reduced, the energy loss of the airflow during the transmission process can be reduced, so that more energy can be used for the solidification process, and the cooling of the liquid can be accelerated to make it into metal powder.

[0018] 2. The present invention utilizes centrifugal force to attach the metal liquid to the inner wall of the barrier ring when the barrier ring rotates, and scrapes the inner wall of the barrier ring through an extrusion piece to separate the metal solution from the inner side of the barrier ring, so that the high-speed airflow can more effectively contact the metal liquid and break it into fine droplets, which helps to improve the solidification efficiency and enables the metal liquid to be more fully broken into the required powder particle size.

[0019] 3. The present invention can indirectly drive the extrusion part to reciprocate on the upper surface of the blocking ring when the rotating part rotates, which can prevent the metal liquid from sticking to the extrusion part and the inner wall of the blocking ring, reducing production interruptions caused by adhesion, thereby improving production efficiency. Avoiding adhesion also helps the metal liquid to form high-quality metal powder during the solidification process.

[0020] 4. The present invention can indirectly drive the blocking member to move upward when the scraper moves upward, so that the upper surface of the blocking member can fit the bottom of the fixed ring, allowing the gas to circulate in the reaction barrel, which helps to enhance the continuous impact effect of the gas on the metal liquid, so that it can be more effectively broken into powder, and the gas can also transfer more energy to the metal liquid, promoting the rapid cooling and solidification of the metal liquid.

[0038] refer to Figure 8 and Fig. 9The cam 32 is connected to the second end of the first telescopic member 21 and the second telescopic member 21 ...

[0039] refer to Fig.10 and Fig.11 As shown, a kind of iron silicon aluminum powder production equipment based on the gas atomization powder making process is shown, the scraper 14 is fixedly connected to the inner side of the second telescopic member 41, the scraper 14 is used to drive the second telescopic member 41 to move up and down at the same time, the bottom of the second telescopic member 41 is slidably connected with a slide rail 4, the second telescopic member 41 is used to drive the slide rail 4 to move up and down at the same time, the lower surface of the slide rail 4 is fixedly connected with a blocking member 42, the slide rail 4 is used to drive the second telescopic member 41 to move up and down at the same time, the upper surface of the blocking member 42 is slidably sealed with the bottom of the fixed rod 12, and the blocking member 42 is used to seal and fit the bottom of the air blocking ring 111 when it moves upward, and the scraper 14 can indirectly drive the blocking member 42 to move upward when it moves upward, so that the upper surface of the blocking member 42 can fit the bottom of the fixed ring 112, so that the gas can circulate in the reaction barrel 11, which helps to enhance the continuous impact effect of the gas metal liquid and make it more effectively broken into powder.

[0040] The complete working principle and steps of the above embodiment are as follows:

[0041] refer to Figures 1 to 5 As shown, when the production equipment is in the initial state, the motor 13 is in the off state, the sliding frame 116 is threadedly connected to the outer surface of the bottom of the first screw rod 114, and the tray 15 is slidably engaged with the outer surface of the bottom of the rotating rod 113;

[0042] When the staff uses the device to process the sendust powder, the metal solution is poured from the feed port on the top of the reaction barrel 11. At this time, the metal solution will flow into the inner wall of the tray 15, and then the motor 13 is started. When the motor 13 rotates, it can drive the first screw 114 to rotate at the same time. When the first screw 114 rotates, it will drive the rotating rod 113 fixedly connected to the top of the first screw 114 to rotate at the same time. As the rotating rod 113 rotates, it will drive the tray 15 slidably connected to the bottom of the rotating rod 113 to rotate at the same time, causing the tray 15 to rotate on the outer surface of the bottom of the rotating rod 113. At this time, The tray 15 will spread the metal liquid through centrifugal force. Since the two ends of the sliding frame 116 are slidably connected to the outer surface of the limit rod 117, the first screw 114 will drive the sliding frame 116 to move upward on the outer surface of the first screw 114 when it rotates. When the sliding frame 116 moves upward, it will drive the push rod 118 symmetrically fixed to the upper surface of the sliding frame 116 to move upward at the same time. Since the upper surface of the push rod 118 slides and fits the bottom of the tray 15, the tray 15 will be pushed upward at the same time as the push rod 118 moves upward. Since the scraper 14 at the bottom of the tray 15 has The bottom of the scraper 14 can slide in the annular groove on the upper surface of the air blocking ring 111 when the tray 15 moves upward, and the metal liquid inside the tray 15 will be closer to the gas collecting ring 16 when the tray 15 moves upward. At this time, the gas inside the nitrogen tank 17 will be transported to the inner wall of the connecting ring 110 through the conduit 18, and the gas inside the connecting ring 110 will be transported to the inside of the gas collecting ring 16 through the air pipe 19. At this time, the gas can be ejected from the bottom of the gas collecting ring 16, so that the high-speed airflow can more effectively impact the metal liquid and break it into smaller and more uniform droplets. The closer the distance to the air collecting ring 16 is, the less energy loss of the air flow during transmission can be achieved, so that more energy can be used for the solidification process. The solidified metal liquid will slide from the upper surface of the tray 15 to the bottom of the reaction barrel 11, and some residual metal powder will slide into the annular groove on the inner side of the air blocking ring 111. When the tray 15 rotates, the scraper 14 at the bottom will rotate at the same time, so that the bottom of the scraper 14 can scrape the metal powder remaining in the annular groove of the air blocking ring 111 out of the square hole on the upper surface of the air blocking ring 111, thereby effectively collecting the metal powder.

[0043] refer to Figure 6 and Figure 7 As shown, when the production equipment is in the initial state, the first telescopic member 21 is in an extended state, the upper surface of the blocking ring 2 is higher than the upper surface of the tray 15, and the pressure spring 23 is in a naturally relaxed state;

[0044] Since the top of the first telescopic member 21 is fixedly connected to the inner wall of the reaction barrel 11, and when the tray 15 rotates, the metal liquid will adhere to the inner wall of the blocking ring 2 due to centrifugal force, so that the gas collecting ring 16 can extend the jetting time of the metal liquid in the blocking ring 2, and at this time, the upper surface of the tray 15 will slide against the bottom of the first telescopic member 21, and the extrusion member 24 on the outer surface of the bottom of the first telescopic member 21 will fit against the inner wall of the blocking ring 2. As the tray 15 drives the blocking ring 2 to rotate, the outer surface of the extrusion member 24 will scrape the metal liquid on the inner wall of the blocking ring 2 to separate the metal liquid from the inner side of the blocking ring 2, thereby increasing the reaction time between the gas and the metal liquid, and enabling the high-speed airflow to more effectively interact with the metal liquid. The liquid contacts and breaks into fine droplets, which helps to improve the curing efficiency, and as the tray 15 moves upward, the first telescopic member 21 is prompted to shrink inward, so that the outer surface of the extrusion member 24 can always be slidably connected to the inner wall of the blocking ring 2, and when the tray 15 drives the blocking ring 2 to move upward, the upper surface of the blocking ring 2 will fit the bottom of the contact member 25. At this time, when the tray 15 continues to drive the blocking ring 2 upward, the blocking ring 2 will squeeze the contact member 25 to force the blocking ring 2 to slide downward, and when the blocking ring 2 slides downward on the inside of the tray 15, the pressure spring 23 at the bottom of the blocking ring 2 is moved to a compressed state. At this time, the metal liquid on the upper surface of the tray 15 can solidify and slide out from the upper surface of the tray 15.

[0045] When the tray 15 drives the blocking ring 2 to move downward, the top of the blocking ring 2 will be out of contact with the contact piece 25. At this time, the pressure spring 23 in the compressed state will drive the blocking ring 2 to move upward, causing the blocking ring 2 to return to its initial state. When the tray 15 moves downward, the bottom of the first telescopic piece 21 will also extend outward and fit the upper surface of the tray 15.

[0046] refer to Figure 8 and Fig. 9As shown, as the rotating rod 113 rotates, the rotating member 3 fixedly connected to the outer surface of the rotating rod 113 will be driven to rotate simultaneously. As the rotating member 3 rotates, the outer surface of the rotating member 3 will squeeze the outer surface of the toggle member 31 and cause the toggle member 31 to rotate. When the toggle member 31 rotates, the second screw rod 32 will be driven to rotate simultaneously. When the second screw rod 32 rotates, the guide rod 33 threadedly connected to the outer surface of the second screw rod 32 will be driven to reciprocate. Since the bottom of the guide rod 33 on the side close to the toggle member 31 is fixedly connected to the output end of the top of the first telescopic member 21, and the guide rod 33 away from the toggle member 31 is fixedly connected to the output end of the top of the first telescopic member 21, the guide rod 33 on the side close to the toggle member 31 is fixedly connected to the output end of the top of the first telescopic member 21. The bottom of the guide rod 33 on one side is fixedly connected to the fixed end at the top of the first telescopic member 21. As the guide rod 33 moves back and forth, the output end of the first telescopic member 21 will be driven to move simultaneously. When the output end of the first telescopic member 21 moves back and forth, the extrusion member 24 will be driven to move simultaneously. At this time, the outer surface of the extrusion member 24 can be separated from the inner wall of the blocking ring 2, which can prevent the metal liquid from sticking to the inner wall of the extrusion member 24 and the blocking ring 2, reducing production interruptions caused by adhesion, thereby improving production efficiency. Avoiding adhesion also helps the metal liquid to form high-quality metal powder during the solidification process.

[0047] refer to Fig.10 and Fig.11 As shown, when the tray 15 rotates, the scraper 14 will drive the second telescopic member 41 to rotate at the same time, and the second telescopic member 41 will rotate on the outer surface of the slide rail 4 when it rotates. As the tray 15 moves upward, the scraper 14 will drive the second telescopic member 41 to move at the same time, and the second telescopic member 41 will move upward with the slide rail 4. When the slide rail 4 moves upward, it drives the bottom blocking member 42 to move at the same time. At this time, when the blocking member 42 moves upward, the upper surface of the blocking member 42 will be pressed against the upper surface of the fixing ring 112. When the scraper 14 then drives the second telescopic member 41 to move upward, the bottom of the second telescopic member 41 will extend downward to avoid excessive squeezing of the blocking member 42 and the fixing ring 112. When the blocking member 42 is pressed against the bottom of the bottom of the fixing ring 112, the fixing ring 112 is in a sealed state. At this time, the gas can circulate in the reaction barrel 11, which helps to enhance the continuous impact effect of the gas on the metal liquid, so that it can be more effectively broken into powder, and the gas can also transfer more energy to the metal liquid, promoting the rapid cooling and solidification of the metal liquid.
