Description

Technical Field

[0001] This invention belongs to the technical field of high-pressure gas powder making equipment, specifically a high-pressure gas atomization device for preparing metal powder. Background Technology

[0002] The high-pressure gas atomization equipment for metal powder preparation is a device that melts metal into a liquid state in a vacuum / inert gas closed environment. The molten metal forms a stable and continuous liquid flow through a preheating guide tube. High-pressure pure argon / nitrogen forms a high-speed jet through a supersonic nozzle, which impacts and shears the molten metal flow, breaking the melt into micron-sized droplets. The droplets are cooled at high speed in the atomization tower and solidify into highly spherical metal powder by contraction due to surface tension. Finally, the gas and powder are separated and collected in stages.

[0003] In the high-pressure gas atomization metal powder preparation process, the mixed gas flow after melting and atomization carries the metal powder into a cyclone separator to complete gas-solid separation. To meet the requirements of powder collection and airtight inert protection, the existing cyclone separator adopts a fully sealed cavity structure. A narrow-diameter powder outlet is set at the bottom of the equipment to continuously discharge metal powder, and an air outlet is opened at the top of the cavity and equipped with a filter screen to intercept fine powder, allowing only clean inert gas to flow outward.

[0004] In actual continuous production, due to the small diameter of the powder outlet at the bottom of the separator and the poor flowability of ultrafine metal powder, it is very easy for it to bridge and accumulate at the outlet, causing blockage. After the powder outlet at the bottom of the separator is blocked, the gas and powder can only be discharged from the top air outlet. The filter screen at the top air outlet will gradually accumulate metal powder. The powder continuously accumulates and covers the filter screen mesh, gradually causing blockage at the air outlet. Since the cyclone separator is completely sealed and has no adaptive pressure relief structure, when any one or both of the bottom powder outlet and the top air outlet are blocked at the same time, the airflow inside the separator cannot be discharged normally, and the pressure inside the cavity continues to accumulate and rise, forming a high-pressure sealed cavity. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention proposes a high-pressure gas atomization device for metal powder preparation. This invention primarily addresses the problem of cyclone separators requiring manual shutdown for unblocking when the discharge port and air outlet are clogged, thus affecting production and posing safety hazards.

[0006] The technical solution adopted by this invention to solve its technical problem is: a high-pressure gas atomization device for metal powder preparation, including an atomizing tank, a cyclone separator disposed on one side of the atomizing tank, and further comprising: The high-pressure deformation relief mechanism is located at the bottom of the cyclone separator. An energy storage vibration cleaning mechanism is installed inside the high-pressure deformation relief mechanism; The high-pressure deformation relief mechanism includes a movable rod that is movably connected to the bottom of the outer wall of the cyclone separator. Connecting plates are provided on both sides of the outer wall of the movable rod. An inner connecting rod is hinged to the outer wall of the movable rod. A fixed rod is also provided. A movable block is movably provided on the outer wall of the fixed rod. A linkage rod is arranged around the outer wall of the movable block. The connecting piece is made of fluorosilicone rubber; The movable rods are distributed in an umbrella-like structure; The energy storage vibration cleaning mechanism includes a pressure block connected to one end of a linkage rod, a slider movably disposed on one side of the pressure block, and a vibration block disposed on the top of the slider; The pressure block is aligned with one end of the air outlet on the inner wall of the cyclone separator. When the umbrella-shaped structure of the movable rod expands and deforms at the bottom of the cyclone separator to increase pressure, it expands the bottom cavity to release pressure. The expansion of the movable rod synchronously drives the slider to store energy and bounce up, which drives the vibrating block to rebound quickly and hit the filter screen at the air outlet of the separator, knocking off the iron powder accumulated on the filter screen, thereby simultaneously clearing the two powder blockage points at the discharge port and the air outlet.

[0007] Furthermore, a main compression spring is provided at the top of the outer wall of the movable block; One end of the fixing rod is connected to a connecting rod; The connecting rod is connected to the inner wall of the cyclone separator.

[0008] Furthermore, a protrusion is provided on one side of the outer wall of the pressure block; The pressure block is provided with an external mounting plate; The pressure block is slidably assembled onto the outer wall of the mounting plate.

[0009] Furthermore, a sliding rod is movably provided on the inner wall of the slider; One end of the slide rod is provided with a pressure block; A compression spring is arranged around the other end of the slide rod.

[0010] Furthermore, a bottom block is provided at the bottom of the pressure block; A telescopic rod is connected to the bottom of the outer wall of the slider; The outer wall of the telescopic rod is surrounded by a double-compression spring.

[0011] Furthermore, the linkage rod is arranged in an equal-angle ring on the outer wall of the movable block; One end of the main compression spring is connected to the outer wall of the fixed rod; The other end of the main compression spring is connected to the outer wall of the movable block.

[0012] Furthermore, one end of the inner connecting rod is movably connected to the outer wall of the movable block; The other end of the inner connecting rod is movably connected to the outer wall of the movable rod.

[0013] Furthermore, the bottom of the outer wall of the pressure block is inclined; The slider has a cavity.

[0014] Furthermore, the slide bar extends through the cavity of the slider; The front section of the slider cavity is square; The rear section of the slider cavity is circular.

[0015] Furthermore, the top of the outer wall of the base block is inclined; The top of the outer wall of the bottom block is aligned with the bottom of the outer wall of the pressure block.

[0016] The beneficial effects of this invention are as follows: 1. The high-pressure deformation relief mechanism, in conjunction with the umbrella-shaped movable rod and the fluorosilicone rubber connecting plate, enables adaptive deformation detection based on internal pressure changes in the cyclone separator. When powder blockage and pressure buildup occur at the bottom powder outlet and top air outlet of the cyclone separator, the internal air pressure expansion force directly drives the movable rod and connecting plate to passively expand and deform, automatically amplifying the bottom cavity space of the cyclone separator and releasing the internal high pressure. No manual monitoring or manual pressure relief is required, which can quickly eliminate the hidden danger of pressure buildup inside the separator and effectively avoid safety problems such as air leakage, powder oxidation, equipment cracking, and dust explosion caused by high pressure in the sealed cavity. At the same time, it can open the blocked discharge port, assisting the smooth discharge of accumulated metal powder at the bottom, avoiding continuous material blockage that affects the gas-powder separation efficiency, and ensuring the continuous and stable production operation of the high-pressure gas atomization equipment.

[0017] 2. Through the high-pressure deformation relief mechanism and the energy-storing vibration cleaning mechanism, the movable rod expands under pressure to release pressure, while simultaneously driving the inner connecting rod to swing. This, along with the synchronous displacement transmission of the movable block and the linkage rod, drives the pressure block, slider, telescopic rod, and other components to compress and store energy. The instantaneous rebound potential energy of the compressed spring and the recompressed spring drives the vibration block to quickly impact the cyclone separator's outlet filter screen, automatically vibrating and knocking off the fine metal powder accumulated on the filter screen surface. This achieves synchronous self-cleaning of the filter screen under clogging conditions, continuously ensuring smooth airflow at the outlet. This avoids the problem of pressure buildup in the cavity caused by filter screen clogging from the source, significantly reducing the probability of equipment blockage failure and the maintenance cost of manual disassembly and cleaning, and comprehensively improving the safety of equipment operation.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 15 As shown, a high-pressure gas atomization device for preparing metal powder includes an atomizing tank 1, a cyclone separator 2 disposed on one side of the atomizing tank 1, and further includes: The high-pressure deformation relief mechanism 3 is located at the bottom of the cyclone separator 2; Energy storage vibration cleaning mechanism 4 is installed inside the high-pressure deformation relief mechanism 3; The high-pressure deformation relief mechanism 3 includes a movable rod 301 that is movably connected to the bottom of the outer wall of the cyclone separator 2. Connecting pieces 302 are provided on both sides of the outer wall of the movable rod 301. An inner connecting rod 303 is hinged to the outer wall of the movable rod 301. A fixed rod 304 is also provided. A movable block 305 is movably provided on the outer wall of the fixed rod 304. A linkage rod 307 is arranged around the outer wall of the movable block 305. The connecting piece 302 is made of fluorosilicone rubber; The movable rod 301 is distributed in an umbrella-like structure; The energy storage vibration cleaning mechanism 4 includes a pressure block 401 connected to one end of the linkage rod 307, a slider 403 movably disposed on one side of the pressure block 401, and a vibration block 410 disposed on the top of the slider 403. The pressure block 401 is aligned with one end of the air outlet on the inner wall of the cyclone separator 2; When the bottom of the cyclone separator 2 is blocked and pressurized, the umbrella-shaped structure of the movable rod 301 expands and deforms, expanding the bottom cavity to release pressure. The expansion of the movable rod 301 synchronously drives the slider 403 to store energy and bounce up, which drives the vibrating block 410 to quickly rebound and hit the filter screen at the air outlet of the separator, knocking off the iron powder accumulated on the filter screen, thereby simultaneously clearing the two powder blockage points at the discharge port and the air outlet.

[0022] In this embodiment, a main compression spring 306 is provided on the top of the outer wall of the movable block 305; One end of the fixing rod 304 is connected to the connecting rod 308; The connecting rod 308 is connected to the inner wall of the cyclone separator 2.

[0023] Specifically, the high-pressure deformation relief mechanism 3, in conjunction with the umbrella-shaped movable rod 301 and the fluorosilicone rubber connecting piece 302, enables adaptive deformation detection based on internal pressure changes in the cyclone separator 2. When powder blockage and pressure buildup occur at the bottom powder outlet and top air outlet of the cyclone separator 2, the internal air pressure expansion force directly drives the movable rod 301 and connecting piece 302 to passively expand and deform, automatically amplifying the bottom cavity space of the cyclone separator 2 and releasing the internal high pressure. No manual monitoring or manual pressure relief is required, which can quickly eliminate the hidden danger of pressure buildup inside the separator and effectively avoid safety problems such as air leakage, powder oxidation, equipment cracking, and dust explosion caused by high pressure in the sealed cavity. At the same time, it can open up the blocked discharge port, assisting the smooth discharge of accumulated metal powder at the bottom, avoiding continuous material blockage that affects the gas-powder separation efficiency, and ensuring the continuous and stable production operation of the high-pressure gas atomization equipment.

[0024] In this embodiment, a protrusion 402 is provided on one side of the outer wall of the pressure block 401; The pressure block 401 is provided with an mounting plate 411 on its exterior; The pressure block 401 is slidably assembled on the outer wall of the mounting plate 411.

[0025] Specifically, the high-pressure deformation relief mechanism 3 and the energy storage vibration cleaning mechanism 4 cause the movable rod 301 to expand and release pressure, while simultaneously driving the inner connecting rod 303 to swing. This, in turn, drives the movable block 305 and the linkage rod 307 to move synchronously, causing the pressure block 401, slider 403, telescopic rod 408 and other components to compress and store energy. The instantaneous rebound potential energy of the compressed spring 406 and the recompressed spring 409 drives the vibration block 410 to quickly impact the filter screen at the outlet of the cyclone separator 2, automatically vibrating and knocking off the fine metal powder accumulated on the surface of the filter screen. This achieves synchronous self-cleaning of the filter screen under clogging conditions, continuously ensuring smooth airflow at the outlet, avoiding the problem of pressure buildup in the cavity caused by filter screen clogging from the source, significantly reducing the probability of equipment clogging failure and the maintenance cost of manual disassembly and cleaning, and comprehensively improving the safety of equipment operation.

[0026] In this embodiment, a slide rod 404 is movably provided on the inner wall of the slider 403; A pressure block 405 is provided at one end of the slide rod 404; A compression spring 406 is arranged around the other end of the slide bar 404.

[0027] Specifically, after the gas and metal powder are discharged from the atomizing can 1 into the cyclone separator 2, the gas and metal powder will be separated inside the cyclone separator 2. At this time, the cyclone separator 2 is under normal pressure. However, because the powder outlet at the bottom of the cyclone separator 2 is small, if powder accumulates or becomes blocked, the gas and metal powder inside the cyclone separator 2 will not be able to separate normally. This will cause the powder and gas to be discharged from the air outlet at the top of the inner wall of the cyclone separator 2, resulting in powder accumulation and blockage at the filter screen at the air outlet of the cyclone separator 2.

[0028] In this embodiment, a bottom block 407 is provided at the bottom of the pressure block 405; A telescopic rod 408 is connected to the bottom of the outer wall of slider 403; A compression spring 409 is provided around the outer wall of the telescopic rod 408.

[0029] Specifically, when a blockage occurs, because the cyclone separator 2 is in a sealed circulation state, the pressure inside the cyclone separator 2 will gradually increase. After the pressure inside the cyclone separator 2 increases, the continuous entry of gas will generate an expansion force. This expansion force will cause the movable rod 301 and the connecting plate 302 to be under pressure. At this time, the movable rod 301 and the connecting plate 302 will be driven to expand. When the movable rod 301 expands, the connecting plate 302 will be slightly stretched. At the same time, the expansion of the movable rod 301 will also drive the inner connecting rod 303 to swing.

[0030] In this embodiment, the linkage rod 307 is arranged in an equal-angle ring on the outer wall of the movable block 305; One end of the main compression spring 306 is connected to the outer wall of the fixing rod 304; The other end of the main compression spring 306 is connected to the outer wall of the movable block 305.

[0031] Specifically, the movable rod 301 and the connecting piece 302 will be driven to expand. When the movable rod 301 expands, the connecting piece 302 will be slightly stretched. At the same time, the expansion of the movable rod 301 will also drive the inner connecting rod 303 to swing. When the inner connecting rod 303 swings, one end will drive the movable block 305 to slide down along the outer wall of the fixed rod 304. When the movable block 305 slides down, it will drive the main pressure spring 306 to be stretched. When the movable rod 301 expands, the space at its bottom will also increase, so that the powder accumulated at the bottom of the movable rod 301 can be discharged.

[0032] In this embodiment, one end of the inner connecting rod 303 is movably connected to the outer wall of the movable block 305; The other end of the inner connecting rod 303 is movably connected to the outer wall of the movable rod 301.

[0033] Specifically, when the movable block 305 slides, it will drive the linkage rod 307 surrounding its outer wall to move downward synchronously. Since one end of the linkage rod 307 is connected to the pressure block 401, the linkage rod 307 will drive the pressure block 401 to slide downward along the outer wall of the mounting plate 411 when it moves downward. When the pressure block 401 initially slides downward, the protrusion 402 on one side of the outer wall of the pressure block 401 will touch the top of the outer wall of the pressure block 405 and drive the pressure block 405 to slide downward synchronously. When the pressure block 405 slides downward, it will drive the slider 403 to slide downward synchronously. When the slider 403 slides downward, the telescopic rod 408 and the pressure spring 409 will be compressed to generate a rebound force.

[0034] In this embodiment, the bottom of the outer wall of the pressure block 405 is inclined; The slider 403 has a cavity.

[0035] Specifically, when the pressure block 405 moves to the bottom block 407, the bottom of the outer wall of the pressure block 405 is pressed against the bottom block 407, causing the pressure block 405 to slide to one side along the outer wall of the bottom block 407. When the bottom block 407 slides to one side, it moves to the front square part of the cavity of the slider 403. At the same time, when the pressure block 405 slides to one side, it drives the slide rod 404 to slide to one side. When the slide rod 404 slides, it drives the compression spring 406 to be stretched. When the pressure block 405 slides, the pressure block 401 is driven by the linkage rod 307 to continue sliding downward until it is disengaged from the mounting plate 411. At the same time, because the pressure block 401 is disengaged, the top of the pressure block 405 is no longer limited by the protrusion 402.

[0036] In this embodiment, the slide bar 404 passes through the cavity of the slider 403; The front section of the cavity of slider 403 is square; The rear section of the 403 cavity is circular.

[0037] Specifically, at this time, the telescopic rod 408 and the pressure spring 409 will release the elastic force, causing the slider 403 to quickly reset. When the slider 403 moves upward, the pressure block 405 will be reset by the pressure spring 406 through the slide rod 404 because the bottom block 407 is no longer limiting it. When the slider 403 pops up quickly, it will vibrate the filter screen at the air outlet of the cyclone separator 2 through the vibration block 410, causing the powder accumulated on the filter screen at the air outlet of the cyclone separator 2 to be vibrated and fall off.

[0038] In this embodiment, the top of the outer wall of the bottom block 407 is inclined; The top of the outer wall of the bottom block 407 is aligned with the bottom of the outer wall of the pressure block 405.

[0039] Specifically, when the slider 403 pops up quickly, it will vibrate the filter screen at the air outlet of the cyclone separator 2 through the vibrating block 410, causing the powder accumulated on the filter screen at the air outlet of the cyclone separator 2 to be vibrated and fall off. After the blockage inside the cyclone separator 2 is resolved, the internal pressure of the cyclone separator 2 is gradually released, allowing the gas and powder to circulate normally. At this time, the main pressure spring 306 will drive the movable block 305 to reset. When the movable block 305 resets, it will drive the movable rod 301 to reset through the inner connecting rod 303.

[0040] During operation, after the gas and metal powder are discharged from the atomizing can 1 into the cyclone separator 2, they are separated inside the cyclone separator 2. At this time, the cyclone separator 2 is under normal pressure. However, because the powder outlet at the bottom of the cyclone separator 2 is small, if powder accumulates or becomes blocked, the gas and metal powder inside the cyclone separator 2 cannot be separated normally. This causes the powder and gas to be discharged from the air outlet at the top of the inner wall of the cyclone separator 2, resulting in powder accumulation and blockage of the filter screen at the air outlet of the cyclone separator 2. When blockage occurs, because the cyclone separator 2 is in a sealed circulation state, the pressure inside the cyclone separator 2 will gradually increase, causing the pressure inside the cyclone separator 2 to rise. As the internal pressure increases, the continuous inflow of gas generates an expansion force, which puts the movable rod 301 and the connecting piece 302 under pressure. At this time, the movable rod 301 and the connecting piece 302 will be driven to expand. When the movable rod 301 expands, the connecting piece 302 will be slightly stretched. At the same time, the expansion of the movable rod 301 will also drive the inner connecting rod 303 to swing. When the inner connecting rod 303 swings, one end will drive the movable block 305 to slide down along the outer wall of the fixed rod 304. When the movable block 305 slides down, it will drive the main pressure spring 306 to stretch. When the movable rod 301 expands, the space at its bottom will also increase, allowing the powder accumulated at the bottom of the movable rod 301 to be discharged.

[0041] When the movable block 305 slides, it drives the linkage rod 307, which is arranged around its outer wall, to move downwards synchronously. Since one end of the linkage rod 307 is connected to the pressure block 401, and the pressure block 401 is slidably mounted on the outer wall of the mounting plate 411, the linkage rod 307, when moving downwards, drives the pressure block 401 to slide downwards along the outer wall of the mounting plate 411. When the pressure block 401 initially slides downwards, the protrusion 402 on one side of the outer wall of the pressure block 401 touches the top of the outer wall of the pressure block 405, causing the pressure block 405 to slide downwards synchronously. As the pressure block 405 slides downwards, it drives the slider 403 to slide downwards synchronously. When the slider 403 slides downwards, it extends the telescopic rod... 408 and the compression spring 409 will be compressed to generate a rebound force. When the pressure block 405 moves to the bottom block 407, the bottom of the outer wall of the pressure block 405 will be pressed against the bottom block 407, causing the pressure block 405 to slide to one side along the outer wall of the bottom block 407. When the bottom block 407 slides to one side, it will move to the front square part of the cavity of the slider 403. At the same time, when the pressure block 405 slides to one side, it will drive the slide rod 404 to slide to one side. When the slide rod 404 slides, it will drive the compression spring 406 to stretch. When the pressure block 405 slides, the pressure block 401 will be driven by the linkage rod 307 to continue sliding downward until it is disengaged from the mounting plate 411. At the same time, because the pressure block After 401 disengages, the top of the pressure block 405 is no longer limited by the protrusion 402. At this time, the telescopic rod 408 and the pressure spring 409 will release the elastic force, causing the slider 403 to quickly reset. When the slider 403 moves upward, the pressure block 405, no longer limited by the bottom block 407, will be reset by the pressure spring 406 via the slide rod 404. When the slider 403 pops upward quickly, it will vibrate the filter screen at the air outlet of the cyclone separator 2 through the vibrating block 410, causing the powder accumulated on the filter screen at the air outlet of the cyclone separator 2 to be vibrated and fall off. After the blockage inside the cyclone separator 2 is cleared, the internal pressure of the cyclone separator 2 is released. As the force is gradually released, the gas and powder circulate normally. At this time, the main pressure spring 306 will drive the movable block 305 to reset. When the movable block 305 resets, it will drive the movable rod 301 to reset through the inner connecting rod 303. At the same time, when the movable block 305 resets, it will also drive the linkage rod 307 to reset. When the linkage rod 307 resets, it will move vertically upward (because the reset trajectory of the linkage rod 307 is the same as the reset trajectory of the movable block 305, and the reset trajectory of the movable block 305 is vertically sliding up and down along the outer wall of the fixed rod 304). At the same time, it will drive the pressure block 401 to slide vertically upward. The pressure block 401 will gradually be driven to reset and slide to the sliding assembly of the mounting plate 411.
