Description

Technical Field

[0001] This invention belongs to the field of atomization powder making technology, specifically a fully automatic vacuum atomization powder making device and processing technology. Background Technology

[0002] Vacuum atomization powder production is an advanced powder production technology that uses high-pressure gas to break molten metal into fine droplets, which are then rapidly solidified into metal powder in a vacuum or inert gas environment. Its core principle is to utilize the kinetic energy of gas to break up the molten metal, combined with the protection of the vacuum environment and the rapid cooling characteristics, to achieve the preparation of high-performance metal and alloy powders. The entire process of vacuum atomization powder production can be summarized into five key steps: "melting → guiding → atomization → cooling and solidification → powder collection and sieving". Each step is closely linked and together determines the core properties of the powder, such as particle size, morphology, and compositional uniformity.

[0003] After the powder is prepared in the pulverizing furnace, it enters the integrated screening line directly from the discharge port, officially starting the collection stage. Relying on this integrated architecture of pulverizing furnace and screening line, the powder needs to be systematically screened through the screening line during the collection process to accurately obtain the particle size specifications required for production. Since the atomization process of vacuum atomization powder production naturally forms a continuous particle size distribution, and different application scenarios have strict requirements for powder particle size, multi-stage screening operations are required in the collection stage to ultimately ensure that the collected powder particle size meets the application standards.

[0004] In existing fully automatic vacuum atomization powder making equipment, during multi-stage sieving, qualified powder can flow out from the bottom sieve plate and be directly packaged, but unqualified powder will remain in the sieve plates of the corresponding levels. This design makes it impossible to collect unqualified powder in one place for recycling, and staff must manually collect it at different sieve plates. This not only increases the limitations of the equipment but also reduces the powder making efficiency of the equipment. Summary of the Invention

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0044] The discharge screen plate 3 is connected through to the bottom of the multi-stage distribution cylinder 2;

[0045] Two bent bases 5 are symmetrically installed on the top of the annular frame 1; the openings of the two bent bases 5 are arranged opposite each other; the multi-stage distributing cylinder 2 is located between the openings of the two bent bases 5;

[0046] A hook 17 is installed on the locking T-block 4; the hook 17 is used to hang packaging bags, which are used to load qualified powder for discharge; a flow pipe 18 is provided on the side of the multi-stage distributing cylinder 2 away from the discharge screen plate 3, which is connected to the inside of the multi-stage distributing cylinder 2; a cover plate 19 is installed on the flow pipe 18, and the two are locked together; several multi-stage screen plates 20 are installed inside the multi-stage distributing cylinder 2, and the several multi-stage screen plates 20 are arranged at equal intervals from large to small according to the screen hole size;

[0047] Positioning U-shaped seats 21 are fixedly installed on both sides of the multi-stage distributing cylinder 2, with the openings of the two positioning U-shaped seats 21 facing away from each other; a positioning cylinder 22 is fixedly installed inside the positioning U-shaped seat 21; a positioning rotating block 23 is slidably connected to the positioning cylinder 22; a positioning spring 24 is sleeved on the positioning cylinder 22, with one end of the positioning spring 24 fixedly connected to the positioning U-shaped seat 21 and the other end fixedly connected to the positioning rotating block 23; the two positioning rotating blocks 23 are respectively connected to two bending bases 5; a centering energy-consuming component is set on one of the bending bases 5, and the rotating shaft 6 on the bending base 5 is rotatably engaged with the positioning rotating block 23; a drive motor 25 is installed on the other bending base 5, and the positioning rotating block 23 on the bending base 5 is connected to the output end of the drive motor 25;

[0048] After the powder is prepared, it is transferred from the closed atomizing cylinder to the powder collection tank. Qualified powder needs to be collected according to different preparation requirements. The powder in the collection tank is then fed into the multi-stage distribution cylinder 2 through the flow pipe 18. The flow pipe 18 on the multi-stage distribution cylinder 2 is then sealed using a cover plate 19, with a locking connection to prevent the cover plate 19 from detaching and affecting the powder sieving effect. The powder accumulated in the multi-stage distribution cylinder 2 can be sieved by operating the re-acting sieving mechanism. Powder that meets the production requirements flows out through the discharge screen plate 3 at the bottom of the multi-stage distribution cylinder 2. The powder flows into packaging bags for packaging compliant powder; the packaging bags are hung at the bottom of the multi-stage distribution cylinder 2 via hooks 17 to collect compliant powder flowing out from the discharge sieve plate 3; the specific screening process is as follows: when the powder enters the multi-stage distribution cylinder 2 through the flow pipe 18 at the top of the multi-stage distribution cylinder 2, it is placed on the multi-stage sieve plate 20 at the top of the multi-stage distribution cylinder 2. There are several multi-stage sieve plates 20 in the multi-stage distribution cylinder 2, and the sieve holes are arranged at equal intervals from large to small, screening the powder step by step. That is to say, the compliant powder passes through several multi-stage sieve plates 20 in sequence and finally falls onto the discharge sieve plate 3. On plate 3, if the powder meets the production specifications, it will flow out through the discharge sieve plate 3 into the packaging bag, thus completing the multi-stage sieving operation of the prepared powder and avoiding the impact of the powder specifications not meeting the usage requirements on the performance. Multi-stage sieving, by setting sieve surfaces with different mesh sizes (or apertures), gradually screens the material from coarse to fine, effectively avoiding the problems of "coarse particles mixing with fine materials" or "fine particles clogging the sieve plate, resulting in incomplete screening of coarse materials" in single-stage sieving. At the same time, under the action of several multi-stage sieve plates 20, the sieve plates with different apertures have different functions, adopting a "gradual reduction of particle size" approach. The screening logic of "degree" first removes large particles or ultra-coarse materials through coarse screening, reducing the processing pressure of subsequent fine screening. Since the discharge screen plate 3 is used to finally determine the size of the powder to be used, the powder usage specifications are adjusted by changing the discharge screen plate 3 with different apertures during the screening of different batches of powder. If the pressure on the discharge screen plate 3 is too high or the working intensity is too high, it will lead to frequent replacement or maintenance, which will reduce screening efficiency and production efficiency. Therefore, the above-mentioned graded screening is used to reduce the usage intensity of the discharge screen plate 3, thereby increasing the service life of the discharge screen plate 3.

[0049] It is worth mentioning that after the batch of powder is screened, the powder that meets the production specifications will flow out through the discharge screen plate 3, while the unqualified powder will remain at the corresponding multi-stage screen plate 20 because the size of the retained powder exceeds the sieve aperture of the corresponding multi-stage screen plate 20. At this time, by starting the drive motor 25, its output end drives one of the positioning rotating blocks 23 to rotate, which drives the multi-stage distributing cylinder 2 to rotate under the action of the positioning cylinder 22 and the positioning U-shaped seat 21. This causes another positioning rotating block 23 on it to rotate at the bending base 5. By driving the multi-stage distributing cylinder 2 to rotate 180°, the original upward orientation of its flow pipe 18 is adjusted to downward orientation. For example, if there are three multi-stage screen plates 20, initially arranged from top to bottom as large aperture screen plate, medium aperture screen plate, and small aperture screen plate, after the multi-stage distributing cylinder 2 rotates 180° so that the flow pipe 18 is set downward, the multi-stage screen plates 20 inside are arranged from top to bottom as: small, medium, and large aperture screen plates. The multi-stage sieve plate 20 at the bottom has a large aperture. Under the influence of gravity, when the multi-stage distributing cylinder 2 flips, the non-compliant powder that was originally at the bottom of the multi-stage distributing cylinder 2 moves to the top. The apertures of the multi-stage sieve plates 20 below gradually increase, and the powder falls through these multi-stage sieve plates 20 to the bottom of the multi-stage distributing cylinder 2. This allows the non-compliant powder that was originally stuck in the multi-stage distributing cylinder 2 to flow out through the large aperture multi-stage sieve plate 20 at the bottom. This allows for the centralized processing of powder stuck at different multi-stage sieve plates 20 in the multi-stage distributing cylinder 2, preventing non-compliant powder from being stuck in the sieve plates of different levels and affecting the screening effect of the device for the next batch of powder. This allows the device to collect and process these non-compliant powders in one place, avoiding the need for manual collection at different sieve plates, reducing the limitations of the device during use and the workload of the staff, while improving the powder production efficiency and performance of the device.

[0050] In this embodiment, a re-moving sieving mechanism is provided on the annular frame 1. This mechanism is used to sieve out qualified powder. The re-moving sieving mechanism includes a fixed frame 7, which is fixedly installed in the annular frame 1.

[0051] A rotary motor 38 is connected to the top of the fixed frame 7; a first bevel gear 39 is installed on the output end of the rotary motor 38; two drive base plates 40 are symmetrically installed on the top of the fixed frame 7; a drive shaft 41 is connected through the opposite surfaces of the two drive base plates 40, and the two are rotatably engaged; a drive cam 42 is connected to one end of the drive shaft 41, and a second bevel gear 43 is connected to the other end; both second bevel gears 43 are meshed with the first bevel gear 39; a rotating base 44 is fixedly installed on the top of the annular frame 1, which is located above the drive cam 42; a limiting cylinder 45 is connected through the top of the rotating base 44, and the two are slidably engaged; a limiting crossbar 46 is fixedly installed on the end of the limiting cylinder 45 near the drive cam 42, and the bottom of the limiting crossbar 46 is located at the rotation path of the side wall of the drive cam 42;

[0052] A limiting spring 47 is fitted on the limiting cylinder 45. One end of the limiting spring 47 is fixedly connected to the limiting crossbar 46, and the other end is fixedly connected to the rotating base 44. A guide cylinder 48 is installed at the end of the limiting cylinder 45 away from the limiting crossbar 46. A guide support column 49 is slidably connected inside the guide cylinder 48. The side of the multi-stage distributing cylinder 2 near the annular frame 1 is located at the moving path of the guide support column 49. A guide spring 50 is provided inside the guide cylinder 48. One end of the guide spring 50 is fixedly connected to the guide cylinder 48, and the other end is fixedly connected to the guide support column 49.

[0053] The rotary motor 38 is started, causing its output end to drive the first bevel gear 39 to rotate, which in turn meshes with the second bevel gear 43. This, in turn, drives the drive cam 42 to rotate via the drive shaft 41, causing it to continuously contact the bottom of the limiting crossbar 46. Under the action of the limiting spring 47, the limiting crossbar 46 reciprocates at the rotating base 44, keeping the limiting spring 47 in a buffering and reset state. This drives the guide slide 48 to reciprocate, which, under the action of the guide spring 50, continuously drives the guide support column 49 to reciprocate, causing it to continuously contact the bottom of the multi-stage distributing cylinder 2. Each contact causes the multi-stage distributing cylinder 2 to move upward, causing the positioning U-shaped seat 21 on it to move at the positioning block 23 on the bent base 5 via the positioning cylinder 22, keeping the positioning spring 24 in a buffering state. When the guide support column 49 no longer contacts the bottom of the multi-stage distributing cylinder 2, it loses its upward power source, and the positioning spring 24 resets. This allows the multi-stage distributing cylinder 2 to move back and forth, causing the powder on the multi-stage sieve plates 20 inside to be constantly shaken. This disperses the powder on the multi-stage sieve plates 20, preventing the powder from accumulating and clogging the multi-stage sieve plates 20, which would affect the screening effect and efficiency. The guide spring 50 makes the contact between the guide support column 49 and the bottom of the multi-stage distributing cylinder 2 flexible, avoiding the impact on the multi-stage distributing cylinder 2 caused by a rigid connection, which would reduce its service life. This further improves the use effect of the device and the screening effect of the powder. At the same time, the device can also start the drive motor 25, causing the multi-stage distributing cylinder 2 to swing left and right at a high frequency, causing the powder accumulated on the multi-stage sieve plates 20 inside to tilt continuously, avoiding the existence of dead corners that affect the screening effect, further improving the powder production efficiency of the device. This allows the multi-stage distributing cylinder 2 to efficiently screen out compliant powder for use, reducing the limitations of the device during use.

[0054] In this embodiment, a loading and unloading locking control unit is provided on the multi-stage distributing cylinder 2. This unit is used to load and unload discharge screen plates 3 of different specifications onto the multi-stage distributing cylinder 2. The loading and unloading locking control unit includes a locking T-block 4, which is fixedly connected to the side of the discharge screen plate 3 away from the multi-stage distributing cylinder 2.

[0055] Locking column 8 is installed on locking T-block 4; the end of locking column 8 faces the multi-stage distributing cylinder 2.

[0056] The locking square tube 9 is fixedly installed at the bottom of the multi-stage distributing cylinder 2; the opening of the locking square tube 9 faces the locking square column 8, and the two fit together; the locking square column 8 and the locking square tube 9 are in sliding fit.

[0057] A locking spring 10 is located inside the locking square tube 9; one end of the locking spring 10 is fixedly connected to the side of the locking square tube 9 near the locking square post 8, and the other end is located at the moving path of the locking square post 8.

[0058] Locking slot 11; a plurality of locking slots 11 are arranged at equal intervals and are disposed through the side of the locking square post 8;

[0059] A locking slide 12 is fixedly connected to the side of the locking square tube 9; the locking slide 12 and the locking slot 11 are arranged on the same side; a locking slide plate 13 is slidably connected to the locking slide 12.

[0060] A return spring 14 is sleeved on the locking slide 12; one end of the return spring 14 is fixedly connected to the locking slide plate 13, and the other end is connected to the locking limit plate 15; the locking limit plate 15 is fixedly connected to the end of the locking slide 12 away from the locking square tube 9.

[0061] The locking insert 16 is fixedly connected to the side of the locking slide plate 13 near the locking square tube 9; the locking insert 16 is connected through the locking square tube 9; the locking insert 16 passes through the locking square tube 9 and is connected to one of the locking slots 11.

[0062] The device has corresponding sieving conditions for different batches of powder during use, in order to prepare powders of different specifications for use. This requires the multi-stage dispensing cylinder 2 to be able to sieve powders of different sizes. By pulling the locking slide plate 13 outward, it moves to the upper limit of the locking slide column 12, so that the return spring 14 is in a buffer state. Then, the locking insert 16 on the locking slide plate 13 disengages from the locking square cylinder 9 and is no longer connected to the locking slot 11, thereby releasing the limiting setting on the locking square column 8, so that the locking spring 10 in the buffer state no longer... Once the limiting and resetting setting is completed, the discharge screen plate 3 on the locking column 8 can be ejected, so that it is no longer connected to the bottom of the multi-stage distribution cylinder 2, thereby completing the disassembly and setting of the discharge screen plate 3. This allows for maintenance or replacement of discharge screen plates 3 with different apertures. After maintenance or replacement, the locking column 8 on the discharge screen plate 3 is aligned with the locking cylinder 9 at the bottom of the multi-stage distribution cylinder 2 to prevent misalignment of the discharge screen plate 3 from affecting the powder screening effect. When the locking column 8 is aligned with the locking cylinder 9 and is continuously pushed forward, the locking column 8 is limited within the locking cylinder 9. The movement causes the locking spring 10 to be in a buffered state. After the discharge screen plate 3 on the locking column 8 is installed in place, the locking slide plate 13, which was originally pulled outward, is released. The reset spring 14 drives the locking insert 16 to reset and move, so that it passes through the locking cylinder 9 and connects with one of the locking slots 11. This limits the locking column 8 to the current position, thus completing the installation of the discharge screen plate 3. The installation and removal of the discharge screen plate 3 is convenient and quick, and can be completed without the aid of any tools, avoiding the problem of the device being unable to function due to the lack of suitable tools. The method of sieving powders of different specifications reduces the limitations of the device's use while improving the powder-making effect. It is worth mentioning that when the locking column 8 is limited, the locking spring 10, which is in a buffer state, cannot be reset. The resulting elastic force acts on the locking column 8, thereby strengthening the contact strength and friction between the locking slot 11 and the locking block 16. This prevents the discharge screen plate 3 from dislodging due to movement of the locking block 16 caused by non-human factors during use, thus improving the safety of the device and the powder-making effect.

[0063] In this embodiment, a centering energy-consuming component is provided on the bending base 5. This component is used to position the multi-stage distributing cylinder 2. The centering energy-consuming component includes a rotating shaft 6, which is connected to the side of the bending base 5 away from the multi-stage distributing cylinder 2.

[0064] A rotating long block 26 has semi-circular structures on both sides. In its initial position, the connecting line between the centers of the two semicircles of the rotating long block 26 is perpendicular. The rotating long block 26 is connected to the rotating shaft 6. Pressure crossbars 27 are provided on both sides of the rotating long block 26. In the initial position, the pressure crossbars 27 and the rotating long block 26 are arranged parallel to each other. A slot is provided at the middle position of the pressure crossbar 27 near the rotating long block 26. The slot is located at the rotation path of the semi-circular structure on the side of the rotating long block 26. A set of pressing square columns 28 are installed on the opposite sides of the two pressure crossbars 27. Pressing bases 29 are installed on both sides of the bending base 5. The pressing square columns 28 are connected through the pressing bases 29, and the two are slidably engaged. A pressing spring 30 is sleeved on the pressing square column 28. One end of the pressing spring 30 is fixedly connected to the pressure crossbar 27, and the other end is fixedly connected to the pressing base 29. A U-shaped rod 31 is installed on the opposite ends of the two sets of pressing square columns 28.

[0065] Two drag-reducing horizontal blocks 32 are located on both sides of the multi-stage distributing cylinder 2. Each of the two drag-reducing horizontal blocks 32 has a fixed connecting rod 33 connected to its opposite sides. Each of the two fixed connecting rods 33 is connected to two U-shaped rods 31. A set of drag-reducing sliding columns 34 are connected through the opposite sides of each of the two drag-reducing horizontal blocks 32, and the two slide in cooperation. Energy-reducing arc plates 35 are installed at the opposite ends of the two sets of drag-reducing sliding columns 34. Energy-absorbing pads 36 are provided on the side of the energy-reducing arc plates 35 closest to the multi-stage distributing cylinder 2, and the two are initially in contact. A drag-reducing spring 37 is fitted on the drag-reducing sliding column 34. One end of the drag-reducing spring 37 is fixedly connected to the drag-reducing horizontal block 32, and the other end is fixedly connected to the energy-reducing arc plate 35.

[0066] During the multi-stage screening of powder materials using the multi-stage distribution cylinder 2, energy-absorbing pads 36 are in contact with both sides of the cylinder. These pads are mounted on an energy-reducing arc plate 35, which is connected by a drag-reducing sliding column 34 and a drag-reducing cross block 32. If the multi-stage distribution cylinder 2 experiences shaking due to non-human factors during use, the resulting impact force will be offset by the buffering force provided by the energy-absorbing pads 36 and the drag-reducing springs 37. This reduces the impact force on the multi-stage distribution cylinder 2, improves its service life and stability during powder screening, and also reduces the noise generated by the multi-stage distribution cylinder 2 during screening. Notably, the contact surface between the multi-stage distribution cylinder 2 and the energy-absorbing pads 36 is designed with low resistance to avoid excessive friction affecting the multi-stage distribution cylinder's performance. The sieving operation of the powder by the up-and-down movement of the multi-stage distributing cylinder 2 reduces the limitations of the device during use. Simultaneously, after the multi-stage distributing cylinder 2 completes the sieving operation and collects the compliant powder through the discharge screen plate 3, it needs to automatically rotate 180° to reverse its head and tail positions for centralized recycling of unqualified powder from different levels within the multi-stage distributing cylinder 2. This also drives the rotating shaft 6 to synchronously rotate the rotating block 26, causing its semi-circular structures on both sides to contact the pressure crossbars 27 on both sides of the rotating block 26. This causes the block to move at the pressure base 29 via the pressure column 28, keeping the pressure spring 30 in a buffered state. At this time, the two pressure crossbars 27 move in opposite directions, reducing the resistance on the crossbars. Block 32 is moved away from the multi-stage distributing cylinder 2 to prevent the position of the energy-reducing arc plate 35 on the resistance-reducing horizontal block 32 from affecting the flipping operation of the multi-stage distributing cylinder 2. When the semi-circular structure on the side of the rotating long block 26 rotates to the slot at the middle position of the pressure crossbar 27, it indicates that the multi-stage distributing cylinder 2 has been flipped to 90°, so that the two multi-stage distributing cylinders 2 have moved to their maximum position in opposite directions, that is, the energy-reducing arc plate 35 is away from the multi-stage distributing cylinder 2. When the multi-stage distributing cylinder 2 continues to flip to 180°, the semi-circular structure on the side of the rotating long block 26 no longer contacts the slot, and gradually no longer contacts the side of the pressure crossbar 27. Under the action of the pressure spring 30, the two pressure crossbars 27 are gradually reset, so that the two pressure crossbars 27 move relative to each other, and thus... Under the action of the U-shaped rod 31 and the fixed rod 33, the energy-reducing arc plate 35 moves closer to the side wall of the multi-stage distributing cylinder 2 until the multi-stage distributing cylinder 2 rotates 180° to complete the head and tail swap, so that the pressure crossbar 27 is completely reset, and the energy-reducing arc plate 35 on it re-contacts the multi-stage distributing cylinder 2, continuing to reduce the noise of the multi-stage distributing cylinder 2 during use and improve its stability. At the same time, the two energy-reducing arc plates 35 move relative to each other to both sides of the multi-stage distributing cylinder 2. When their position is off or the rotation angle is incorrect, the drag-reducing spring 37 on one side will buffer to varying degrees, which can be used to position the multi-stage distributing cylinder 2 to avoid deviation in its use position or incorrect rotation angle affecting the sieving effect of powder, thereby improving the use effect of the device.Simultaneously, whether the multi-stage distributing cylinder 2 is unloading or resetting, the contact between the two energy-reducing arc plates 35 and the sides of the multi-stage distributing cylinder 2 indicates that its position is limited. This prevents the multi-stage distributing cylinder 2 from shifting its position or becoming unstable during the powder sieving process, thus reducing the powder-making efficiency of the device and further improving the powder-making effect of the device.

[0067] This invention also provides a processing technology for a fully automatic vacuum atomization powder making device, comprising the following steps:

[0068] S1. By operating the loading and unloading lock control unit, the discharge screen plate 3 with different aperture can be replaced, which can be used to produce powder of different sizes.

[0069] S2. Under the action of the re-moving screening mechanism, the powder poured into the multi-stage distribution cylinder 2 can be continuously screened out through the discharge screen plate 3.

[0070] S3. After the powder is sieved, the unqualified powder is retained in the multi-stage distribution cylinder 2. By controlling the flipping collection device, the unqualified powder remaining in the multi-stage distribution cylinder 2 can be uniformly processed.
