The vibration caused by the collision can make the zinc blocks condensed on the surface of the condensing box fall off automatically, effectively avoids the zinc blocks from adhering to the outer side of the condensing box for a long time, and reduces the adverse influence on the subsequent zinc vapor condensation process. Finally, the device realizes the intermittent vibration unloading characteristic of the condensing box, and improves the condensing efficiency.

Description

Technical Field

[0001] This invention relates to the technical field of metal additive powder production, and in particular to an intelligent zinc powder settling device and its control method. Background Technology

[0002] Zinc powder, as an important metal additive powder, has shown broad application potential in the field of additive manufacturing (i.e., 3D printing). Due to its unique physical and chemical properties, zinc powder can not only be used directly as a printing material to construct complex three-dimensional metal structures, but also, by mixing with other metal powders, adjust key indicators such as the mechanical properties, corrosion resistance, and electrical conductivity of printed parts, thereby meeting the diverse needs of different industrial sectors for high-performance metal components. In the zinc powder production process, the zinc powder settling device, used to settle the hot fluid containing zinc powder, plays a crucial role in the zinc powder production process.

[0003] According to the search, CN212551740U discloses a zinc powder settling and cooling device, which includes a left settling tower and a right settling tower, so that the zinc vapor can be settling twice. The auxiliary settling structure and U-shaped channel in the left settling tower can extend the flow time and path of the zinc vapor, so that the zinc vapor can be further stably absorbed, thereby fully improving the efficiency of zinc powder production.

[0004] This shows that extending the airflow path is the main method used to enhance the settling efficiency of zinc vapor. However, in actual production, zinc vapor often contains a small amount of residual moisture. This moisture condenses on the condenser plate along with the zinc vapor during the settling process. As condensation proceeds, zinc lumps gradually accumulate, which not only occupies the effective area of ​​the condenser plate but also further hinders the heat exchange efficiency of the condenser plate, thus reducing its cooling capacity. This phenomenon, in turn, affects the settling efficiency of zinc vapor, leading to a gradual decrease in the overall efficiency of the settling process. Summary of the Invention

[0005] This invention proposes an intelligent zinc powder settling device and its control method. The condenser in this device has the characteristic of intermittent vibration unloading, which aims to solve the problem mentioned in the background art of continuous agglomeration of zinc vapor on the condenser plate, resulting in reduced condensation efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent zinc powder settling device, comprising: a settling tower, inside which a settling inner cylinder is installed, and inside the settling inner cylinder is a condensing box driven by a motor output shaft; a cold flow circulation component for realizing the flow of coolant in the condensing box is installed on the motor output shaft; a top block is fixed on the inner wall of the settling inner cylinder; when the rotating condensing box passes the top block, it moves radially along the motor output shaft and compresses and stores force on the vibrating spring; when the condensing box detaches from the top block, the spring force of the vibrating spring pushes the condensing box to impact the settling inner cylinder, thereby causing the zinc blocks condensed on the outside of the condensing box to fall off.

[0007] Furthermore, the air inlet pipe is installed on the outside of the settling tower, and the end of the air inlet pipe is fixed with an air inlet ring frame located below the condenser box; the upward zinc vapor and the downward zinc block move towards each other, and the two come into contact and achieve counter-current settling between the low-temperature zinc block and the zinc vapor.

[0008] Furthermore, a discharge pipe for discharging zinc powder is fixedly installed at the bottom of the settling tower.

[0009] Furthermore, an air outlet pipe is fixedly installed at the top of the settling tower to clamp and secure the filter plates.

[0010] Furthermore, a fan blade and a reduction gearbox located above the fan blade are fixedly installed on the motor output shaft, and the reduction gearbox enables differential rotation between the condenser and the fan blade; an air inlet slot is opened on the outside of the settling inner cylinder for communication between the inner cavity of the settling tower and the inner cavity of the settling inner cylinder; a filter slot is opened at the bottom of the outside of the settling inner cylinder, and a filter frame is installed on the inside of the settling inner cylinder at the filter slot, and the filter slot on the filter frame filters zinc powder and zinc blocks.

[0011] Furthermore, a grinding disc located at the bottom of the settling inner cylinder is fixedly installed on the motor output shaft.

[0012] Furthermore, an intermediate material-gathering cylinder located above the air intake ring frame is fitted inside the settling inner cylinder. A sealing seat inserted into the filter frame is fixedly installed at the bottom of the air intake ring frame, and a cleaning rod that moves along the filter groove is fixedly installed on the inner side of the sealing seat. A ventilation groove is opened on the outer side of the top of the air intake ring frame.

[0013] Furthermore, a piston rod is movably installed on the side of the intake pipe. The bottom of the piston rod is movably installed between the inner cavity of the intake pipe and the top is fixed to the inner top of the intermediate material cylinder. A spring connects the intake pipe and the intermediate material cylinder.

[0014] Furthermore, the bottom of the condenser box is sloping and an clearance groove is provided above the sloping section, and a closed baffle rod located above the ventilation groove is fixedly installed inside the middle material cylinder.

[0015] A control method for an intelligent zinc powder settling device includes the following steps:

[0016] S1. The condenser in the settling tower is driven to rotate by the output shaft of the motor.

[0017] S2. After zinc vapor enters the settling tower, it passes through the condenser to reduce its temperature and condense into zinc powder.

[0018] S3. When the rotating condenser box passes the top block, the condenser box will move radially along the motor output shaft and compress and store force on the vibrating spring. When the condenser box is separated from the top block, the elastic force of the vibrating spring will push the condenser box to hit the settling inner cylinder, thereby causing the zinc block condensed on the outside of the condenser box to fall off.

[0019] S4. The upward-moving zinc vapor and the downward-moving zinc block after condensation in the condenser move towards each other, and the two come into contact and achieve reverse sedimentation between the low-temperature zinc block and zinc vapor.

[0020] The present invention has the following beneficial effects:

[0021] This invention provides an intelligent zinc powder settling device and its control method, which uses a motor to drive a condenser to rotate at a low speed periodically. When the condenser moves past a preset top block position, it is pushed by the elastic force of a vibration spring, causing an impact. The vibration generated by this impact effectively causes the zinc blocks condensed on the surface of the condenser to fall off autonomously, thus preventing the zinc blocks from adhering to the outside of the condenser for a long time and significantly reducing the adverse effects on the subsequent zinc vapor condensation process. This process enables the condenser to have the characteristic of intermittent vibration unloading, improving condensation efficiency.

[0022] Furthermore, the device is designed with an inlet ring frame located directly below the condenser. When the condensed zinc blocks detach from the condenser under vibration and fall, they create opposing motion with the zinc vapor rising from the inlet ring frame. This opposing motion not only accelerates the cooling of the zinc vapor through temperature difference but also forces the falling, low-temperature zinc blocks to settle in a reverse manner with the zinc vapor. This reverse settling phenomenon further promotes the agglomeration and sedimentation of zinc powder particles. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: In the current booming development of the new materials industry, zinc powder, with its unique physicochemical properties, has secured a place in the metal additive powder market. Through advanced production processes and strict quality control, modern zinc powder manufacturers can produce high-purity, uniformly sized, high-quality zinc powder, providing an ideal raw material choice for metal additive manufacturing. As a key element in the new materials industry, the performance of metal additive powder directly affects the quality and application range of additive manufacturing products. Zinc powder, as an important metal additive powder, demonstrates broad application prospects in aerospace, automotive manufacturing, biomedicine, and other fields due to its excellent plasticity, conductivity, and corrosion resistance. With continuous technological innovation, the position of zinc powder in metal additive powders is becoming increasingly prominent, becoming an important force driving the development of related industries.

[0037] To improve zinc powder production efficiency, please refer to [link / reference]. Figure 1 It can be seen that the settling tower 1 in this equipment is mainly fixed using the mounting brackets set on the outside, ensuring that the settling tower 1 can be vertically and stably supported during operation. Combined with... Figure 2 and Figure 3 It can be seen that motor 2 is bolted to the bottom of settling tower 1, and the output shaft of motor 2 extends into the inner cavity of settling tower 1 and is coaxially arranged with the central axis of settling tower 1. The inner wall of settling tower 1 is bolted to a settling inner cylinder 3 located outside the output shaft of motor 2, as shown below. Figure 3 , Figures 5-7 As shown, several condenser boxes 8 are movably mounted at equal angles on the outer side of the output shaft of motor 2, and the condenser boxes 8 can only reciprocate radially along the output shaft of motor 2. In actual operation, the interior of the condenser boxes 8 is hollow to facilitate the flow of coolant. Regarding the input and output of cooling, from... Figure 3 , Figure 6 and Figure 7 As can be seen, the cold flow circulation assembly 9 is movably installed on the outside of the output shaft of motor 2 at the upper and lower ends of the condenser box 8. The cold flow circulation assembly 9 mainly consists of a coolant inlet pipe, a coolant outlet pipe, a connecting pipe, and a water rotary joint. More specifically, the coolant inlet / outlet pipes are connected to the water rotary joints respectively, and the rotary joints are connected to the inner cavity of the condenser box 8. The other end of the coolant inlet / outlet pipes extends from the side of the settling tower 1. Generally, a circulating liquid pump and a radiator are installed between the coolant inlet / outlet pipes. The circulating pump drives the coolant to circulate in the condenser box 8, ensuring that the actual working temperature of the condenser box 8 can be controlled autonomously according to the usage requirements.

[0038] from Figure 3 and Figure 5 As can be seen, there is a top block 13 on the inner wall of the settling inner cylinder 3, which is fastened with bolts, and the top surface of the top block 13 is a right trapezoid. Figure 5When the condenser 8 shown rotates clockwise, it moves along the inclined plane after passing the top block 13, simultaneously compressing and storing force on the vibrating spring 801. After the condenser 8 passes the top block 13, it is pushed by the elastic force of the vibrating spring 801, causing it to press against the inner wall of the settling inner cylinder 3. The impact causes vibration in the condenser 8, facilitating the removal of the zinc blocks condensed on the outside of the condenser 8. Figure 2 and Figure 3 As shown, an air inlet pipe 600 extending into the middle of the inner cavity of the settling inner cylinder 3 is fixedly installed on the outside of the settling tower 1, and an air inlet ring frame 6 is fixedly installed at the end of the air inlet pipe 600. Zinc vapor is introduced into the air inlet ring frame 6 through the air inlet pipe 600 by means of a fan, and then released into the inner cavity of the settling inner cylinder 3 by the air inlet ring frame 6. When the zinc vapor comes into contact with the condensation box 8, it forces the zinc powder particles to agglomerate and settle. As mentioned above, when the zinc powder on the outside of the condensation box 8 agglomerates into lumps, the condensation box 8 periodically impacts the inside of the settling inner cylinder 3 to dislodge the zinc lumps condensed on the outside of the condensation box 8.

[0039] Moreover, from Figure 2 and Figure 3 As can be seen, the intake ring 6 is located directly below the condenser box 8. In this embodiment, zinc vapor moves upward, while the cooled zinc block / powder moves downward under the influence of gravity. This causes the zinc powder / block and zinc vapor to move towards each other. When the two come into contact, the low-temperature zinc block and zinc vapor undergo reverse sedimentation. This reverse sedimentation phenomenon further promotes the agglomeration and sedimentation of zinc powder particles.

[0040] The zinc powder / lumps will eventually accumulate at the bottom of the settling tower 1 cavity, from... Figure 2 and Figure 3 It can be seen that the discharge pipe 1002, which is fixedly installed at the bottom of the settling tower 1, can discharge zinc powder. It should be noted that under normal circumstances, the discharge pipe 1002 is sealed with a valve and is only opened when unloading is required.

[0041] In actual production, these settled zinc powders cannot be directly applied to additive manufacturing (i.e., 3D printing). Subsequent use requires screening and drying to remove impurities, clumps, and moisture, ensuring uniform particle size and low oxygen content. For example, the zinc powder needs to be finely sieved to control the particle size within the 15-45 μm range to meet the powder flowability requirements of processes such as selective laser melting (SLM). Ultimately, these modification steps significantly improve the stability and molding quality of the zinc powder during 3D printing.

[0042] Example 2 is a further improvement on Example 1. Please refer to Example 1. Figure 3As can be seen, the final exhaust gas will be discharged from the exhaust pipe 1001. In order to reduce the zinc powder carried in the exhaust gas, a filter plate 10 is fixed to the bottom of the exhaust pipe 1001. The filter plate 10 can perform final filtration of the output exhaust gas, thereby preventing zinc powder from being discharged to the outside with the exhaust gas.

[0043] Furthermore, a fan blade 4 is fixedly mounted on the output shaft of motor 2, such as... Figure 2 , Figure 3 and Figure 6 As shown, a reduction gearbox 5 mounted on the intake ring frame 6 is arranged between the output shaft of the fan blade 4 and the condenser box 8. The reduction gearbox 5 is a cylindrical planetary gear reducer that can be purchased directly. When the motor 2 drives the fan blade 4 to rotate rapidly and causes the air inside the settling inner cylinder 3 to flow downward, the reduction gearbox 5 enables the condenser box 8 to rotate at a low speed cyclically. Furthermore, from... Figure 2 and Figure 3 It can be seen that an air inlet groove 301 is provided on the middle of the outer side of the settling inner cylinder 3 and on one side of the condenser box 8. The air inlet groove 301 enables direct communication between the inner cavity of the settling inner cylinder 3 and the settling tower 1. A filter groove 300 is provided at the bottom of the outer side of the settling inner cylinder 3, and a filter frame is installed on the inner side of the settling inner cylinder 3 at the filter groove 300. Figure 2 It is evident that there are multiple sets of filter frames, each corresponding to a filter groove 300. Each set of filter frames mainly consists of two "L"-shaped plates, utilizing the gaps between the plates to filter zinc powder and zinc blocks. Based on the above, when motor 2 drives fan blade 4 to rotate rapidly and generate downward airflow, zinc vapor is simultaneously supplied to the intake ring frame 6 through the intake pipe 600. Therefore, the airflow transported in the intake ring frame 6 flows downward due to the rotation of fan blade 4. Simultaneously, because the intake ring frame 6 is replenished with zinc vapor, a small portion of the air above the intake ring frame 6 and located within the inner cavity of the settling inner cylinder 3 is transported downwards. For actual airflow control, the power of motor 2 and the air delivery volume of the intake ring frame 6 can be determined independently according to the usage scenario and requirements, only needing to ensure that a small portion of the air within the inner cavity of the settling inner cylinder 3 and above the intake ring frame 6 flows downwards. During this process, the zinc powder / lumps condensed and falling from the condensation tank 8 move downwards, thus moving synchronously with the downward-moving zinc vapor, ultimately achieving the reverse settling between the low-temperature zinc blocks and zinc vapor as described in Example 1. Secondly, the downward-moving zinc vapor is transported through the filter tank 300 into the inner cavity of the settling tower 1, from... Figure 3 As can be seen, the airflow moves upward along the inner cavity of the settling tower 1 and is eventually transported into the inner cavity of the settling inner cylinder 3 through the air inlet trough 301. When the zinc vapor passes through the condenser box 8, it condenses and eventually forms zinc powder.

[0044] Since the air intake slot 301 is located on a side relatively far from the top block 13, the two are arranged symmetrically. Figure 3 and Figure 8 It can be seen that most of the zinc vapor entering from the inlet sump 301 is transported upward along the right-side condenser 8, while the zinc powder / block is separated by vibration when the left-side condenser 8 passes the top block 13. At this time, the upward airflow intensity in the left-side chamber is relatively low. The upward airflow and the downward zinc block / powder are no longer directly opposite each other, reducing the impact of the upward airflow on the zinc powder, which is then discharged from the outlet pipe 1001.

[0045] The zinc block eventually settles at the bottom of the settling inner cylinder 3. To ensure the output zinc powder meets usage requirements, a grinding disc 11 is fixedly mounted on the output shaft of motor 2 at the bottom of the settling inner cylinder 3. When the zinc block falls between the grinding disc 11 and the bottom of the settling inner cylinder 3, the grinding disc 11 crushes the zinc block into zinc powder, which then falls to the bottom of the settling tower 1. Finally, when it is necessary to discharge the zinc powder, simply open the discharge pipe 1002.

[0046] Example 3 is a further improvement on Example 2. To facilitate zinc powder discharge and the unclogging of the filter tank 300 and filter plate 10, please refer to [link / reference needed]. Figure 2 , Figure 3 , Figure 6 and Figure 8 As can be seen, the inner settling cylinder 3 is fitted with an intermediate material-gathering cylinder 7 located above the air inlet ring frame 6. The top of the intermediate material-gathering cylinder 7 has a frustum-shaped groove. When the zinc block falls from the condensation box 8, the inclined frustum at the top of the intermediate material-gathering cylinder 7 guides the zinc block. Furthermore, a rectangular groove is also provided on the side of the intermediate material-gathering cylinder 7 to ensure that its vertical movement is not obstructed by the air inlet pipe 600. Several closed baffles 704 inserted into the filter frame are fixedly installed at the bottom of the air intake ring frame 6, and a cleaning rod 703 that moves along the filter tank is fixedly installed on the inner side of the closed baffle 704. When the closed baffle 704 drives the cleaning rod 703 to move up and down, the cleaning work of the filter tank can be realized. A ventilation groove 702 is opened on the outer side of the top of the air intake ring frame 6. When the ventilation groove 702 and the air intake groove 301 are opposite each other, the inner cavity of the settling tower 1 and the settling inner cylinder 3 are connected. When the intermediate material gathering cylinder 7 moves downward, it is blocked by the outer side of the intermediate material gathering cylinder 7, which can relatively block the air intake groove 301, thereby isolating the air flow between the two.

[0047] from Figure 3 and Figure 4It can be seen that a piston rod 12 is movably installed on the side of the intake pipe 600. The bottom of the piston rod 12 is movably installed between the inner cavity of the intake pipe 600 and the top is fixed to the inner top of the intermediate material collection cylinder 7. At the same time, a spring connects the intake pipe 600 and the intermediate material collection cylinder 7. Under normal conditions, when there is airflow in the intake pipe 600, the airflow pushes the piston rod 12 and the spring to push the intermediate material collection cylinder 7 upward, so that the intermediate material collection cylinder 7 rises to its top limit, ensuring that the ventilation slot 702 and the intake slot 301 are connected. Similarly, when the intake pipe 600 stops supplying air, the rotation of the fan blade 4 will cause the airflow above the fan blade 4 to move downward, resulting in a relative decrease in pressure in the chamber above the fan blade 4 and below the intermediate material collection cylinder 7. The middle of the intermediate material collection cylinder 7 cannot quickly replenish the airflow, causing the intermediate material collection cylinder 7 to tend to move downward. In order to ensure that the intake slot 301 and the filter slot 300 can be stably blocked, from Figure 3 and Figure 7 As can be seen, the bottom of the condenser box 8 is sloped. Correspondingly, a sealing baffle 701 is fixedly installed on the inner side of the intermediate material collecting cylinder 7, located above the venting groove 702. When the intermediate material collecting cylinder 7 rises to its top limit, the sealing baffle 701 is near the clearance groove 800 opened in the middle of the condenser box 8, and the two will not come into contact. Conversely, when the sealing baffle 701 moves downward, the slope of the bottom of the condenser box 8 will push the sealing baffle 701 to move downward continuously until the sealing baffle 701 passes over the bottom of the condenser box 8.

[0048] In actual operation: the zinc vapor settling process: as follows Figure 3 and Figure 9 As shown, zinc vapor is transported into the air inlet pipe 600 by means of a fan, etc. During this process, under the premise that the spring and the airflow in the air inlet pipe 600 push the piston rod 12 to move upward, the intermediate material collection cylinder 7 moves upward to the limit. At this time, the sealing seat 704 will not block the filter tank 300, and the ventilation groove 702 and the air inlet groove 301 are connected.

[0049] When motor 2 is working, it drives the grinding disc 11 and fan blade 4 to rotate synchronously at high speed, while the reduction gearbox 5 enables the condenser 8 to rotate at low speed. Then, the rotation of fan blade 4 causes the zinc vapor input from the inlet ring frame 6 to be blown downwards and enters the inner cavity of the settling tower 1 from the filter tank 300. During this process, because a baffle ring is provided in the middle of the inner cavity of the settling tower 1 in the area between the filter tank 300 and the inlet tank 301, such as... Figure 2 and Figure 3 As shown, the baffle ring can further reduce the upward movement of zinc powder with the airflow. Finally, zinc vapor is transported from the inlet trough 301 to the vicinity of the condenser box 8. Most of the zinc vapor is settled by the condenser box 8 on the right side, causing zinc powder / lumps to adhere to the condenser box 8. Finally, the exhaust gas is filtered by the filter plate 10 and discharged from the outlet pipe 1001.

[0050] As described in Embodiment 1 above, when the condenser 8 passes by the top block 13 on the left, it will vibrate and cause the zinc block to fall off. The zinc block falls from the middle material collection cylinder 7 to below the fan blade 4. When the zinc powder / block is conveyed downward synchronously with the zinc vapor, the low-temperature zinc block and the zinc vapor will settle in reverse. Finally, the zinc block will fall onto the grinding disc 11. The grinding disc 11 and the bottom of the motor 2 will crush the zinc block, so that the zinc powder of the correct particle size will accumulate at the bottom of the inner cavity of the settling tower 1.

[0051] Zinc powder discharge process: The air inlet pipe 600 stops supplying air and is blocked. As the motor 2 rotates again, the fan blade 4 will cause the airflow in the upper chamber to flow downward quickly. During this process, since the air inlet ring frame 6 no longer replenishes the airflow above the fan blade 4, and the intermediate material gathering cylinder 7 cannot quickly replenish the airflow in the upper chamber of the fan blade 4, the pressure in the upper chamber of the fan blade 4 is relatively reduced, causing the intermediate material gathering cylinder 7 to tend to move downward and squeeze the spring. The piston rod 12 moves downward synchronously.

[0052] As the intermediate material collection cylinder 7 descends, the sealing baffle 701 descends synchronously and is positioned below the clearance groove 800. When the bottom slope of the condenser box 8 reaches the sealing baffle 701, the slope pushes the sealing baffle 701 downward, increasing its downward movement intensity until the outer side of the intermediate material collection cylinder 7 blocks the air inlet groove 301, and the sealing baffle 704 blocks the filter groove 300. At the same time, as the unblocking rod 703 moves along the filter groove, it simultaneously unblocks the filter groove.

[0053] At this time, the fan blade 4 is still rotating, so the airflow can only flow in the opposite direction through the air outlet pipe 1001. The airflow in the air outlet pipe 1001 impacts the filter plate 10 in the opposite direction, thereby clearing the blockage of the filter plate 10. The zinc powder / lumps accumulated in the inner cavity of the settling inner cylinder 3 and on the filter plate 10 eventually fall onto the grinding disc 11 and are crushed by the grinding disc 11.

[0054] When the discharge pipe 1002 is opened, the airflow is discharged from the gap between the grinding disc 11 and the settling inner cylinder 3, causing the airflow in the inner cavity of the settling tower 1 to be discharged from the discharge pipe 1002. During the movement of the airflow, the zinc powder is also blown outward intensified.

10. A control method for the intelligent zinc powder settling device as described in claim 2, characterized in that, Includes the following steps: S1. The condenser (8) in the settling tower (1) is driven to rotate by the output shaft of the motor (2); S2. After zinc vapor enters the settling tower (1), the zinc vapor passes through the condenser (8) to reduce its temperature and condense into zinc powder. S3. When the rotating condenser (8) passes the top block (13), the condenser (8) will move radially along the output shaft of the motor (2) and compress and store the shock spring (801). When the condenser (8) is separated from the top block (13), the elastic force of the shock spring (801) will push the condenser (8) to hit the settling inner cylinder (3), thereby realizing the removal of the zinc block condensed on the outside of the condenser (8). S4. The upward zinc vapor and the downward zinc block after condensation in the condenser (8) move towards each other, and the two come into contact and achieve reverse sedimentation between the low-temperature zinc block and zinc vapor.
