Description

Technical Field

[0001] This invention relates to the field of TC4 titanium alloy powder conveying technology, specifically to a conveying and feeding mechanism for TC4 titanium alloy powder preparation. Background Technology

[0002] TC4 titanium alloy powder, also known as Ti-6Al-4V alloy powder, is a core material in the field of metal additive manufacturing (3D printing). With its lightweight and high strength (strength exceeding 900MPa), excellent corrosion resistance and biocompatibility, it is widely used in high-end fields such as aerospace engine components and orthopedic implants. In the preparation process of TC4 powder, the feeding mechanism is a key subsystem to ensure the stable production of high-quality powder. Taking the mainstream electrode induction melting gas atomization method as an example, its feeding mechanism needs to feed the pre-alloyed TC4 electrode rod into the induction coil at a constant speed through a high-precision servo system under the protection of an inert atmosphere.

[0003] In existing technology, the mixture of grinding balls, powder, and water-based abrasive in the grinding tank is first poured into a filter basket equipped with a 1-1.5mm filter screen. The grinding balls are separated by sieving, and simultaneously cleaned and recycled by spray rinsing. Subsequently, the slurry obtained from rinsing is introduced into a low-speed centrifuge. Under the protection of nitrogen micro-positive pressure, solid-liquid separation of powder and abrasive is achieved using a polypropylene filter bag of approximately 5000 mesh. The powder is retained in the bag to form a filter cake, while the liquid is collected and pumped back to the spray system for recycling. After separation, the centrifuge is slowed down and stopped, the filter bag is removed, and the wet powder is transferred to a tray. Finally, the recovered TC4 powder is obtained by drying. This process, through multi-stage separation and closed-loop circulation, achieves the resource recovery of grinding media, liquid carrier, and titanium powder.

[0004] However, during operation, the tilting of the filter basket and the start / stop of the spray are not synchronized. When manually pouring the grinding tank into the filter basket, the spray needs to be manually turned on. If it is turned on too early, the grinding agent is wasted, and the TC4 powder attached to the surface of the initially poured grinding balls will dry and form scale quickly because it is not wetted in time, which will aggravate the powder adhesion. This will not only reduce the recovery rate of the current batch, but also cause residual contamination of the grinding balls, affecting the grinding effect of subsequent batches. If it is turned on too late, the powder on the initially poured grinding balls will not be washed off in time, and it will adhere more firmly after drying, reducing the recovery rate. There is also a delay in turning off the spray after tilting, which affects the economy of the entire recovery process and the cleanliness of the recovered powder.

[0005] Although the problem can be solved, during spray rinsing, the water flow can wash away most of the powder, but some fine TC4 titanium alloy powder with high adhesion or high electrostatic adsorption stubbornly adheres to the gaps between the grinding balls and the filter mesh, which cannot be removed by rinsing alone. This results in incomplete recovery of the grinding balls, and the residual powder will contaminate the next batch of materials, clog the filter, reduce filtration efficiency in the long run, and lose powder recovery rate, which directly leads to a decrease in production. Summary of the Invention

[0006] The purpose of this invention is to provide a feeding mechanism for preparing TC4 titanium alloy powder, so as to solve the problems of asynchronous spraying and tilting, and the presence of residues during spraying.

[0008] Preferably, the synchronous tilting spray mechanism includes a second receiving frame, a rotating shaft, a first gear, a second gear, an extension plate, a water tank, a valve, a control rod, and a first connecting water pipe. The lower surface of the second receiving frame is fixedly installed on the right side of the upper surface of the material pouring cart. The outer surface of the rotating shaft is rotatably connected to the inner wall of the second receiving frame. The inside of the first gear is fixedly installed on the outer surface of one end of the rotating shaft. The outer surface of the second gear meshes with the outer surface of the first gear. The left side of the extension plate is fixedly installed on the right side of the material pouring cart. The bottom of the water tank is fixedly installed on the upper surface of the extension plate. The water inlet end of the valve is fixedly installed inside the water tank. The inside of the control rod is connected to the inside of the valve. The inside of the second gear is fixedly installed on the outer surface of one end of the control rod.

[0009] Preferably, the striking mechanism includes a gear three, a limiting block, a rack, a connecting strip, and a striking block. The lower surface of the limiting block is fixedly installed on the right side of the upper surface of the unloading cart. The outer surface of the rack is rotatably connected to the inner wall of the limiting block. The outer surface of the gear three meshes with the upper surface of the rack. One side of the connecting strip is fixedly installed on one side of the rack. One side of the striking block is fixedly installed on the front of the connecting strip.

[0010] Preferably, one end of the rotating shaft is fixedly installed to the right side of the filter basket, and a connecting water pipe is installed at the outlet end of the valve.

[0011] Preferably, a water receiving bucket is installed at the water outlet end of the connecting water pipe, and both sides of the water receiving bucket are fixedly connected to the right side of the drive shaft and the left side of the receiving frame. An inclined nozzle is installed on the lower surface of the water receiving bucket.

[0012] Preferably, the interior of the gear three is fixedly mounted to the outer surface of the rotating shaft.

[0013] Preferably, the outlet end of the valve is fixedly connected to a second connecting water pipe, and one end of the second connecting water pipe is fixedly connected to a second receiving water bucket.

[0014] Preferably, a conveying pipe is fixedly installed on the right side inside the unloading vehicle, and a vertical nozzle is installed inside the conveying pipe. The water inlet of the vertical nozzle is fixedly connected to the inside of the receiving bucket.

[0015] Preferably, a centrifuge is installed at the water outlet of the conveying pipeline, and a nitrogen protective gas inlet is installed at the top of the centrifuge.

[0016] Preferably, a pump body is installed at the bottom of the centrifuge, a transmission pipe is fixedly installed at the water outlet end of the pump body, and a water-based abrasive transfer tank is fixedly installed at one end of the transmission pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention uses a drive motor to rotate and tilt the drive shaft and filter basket. Through the meshing transmission of the rotating shaft, gear one, and gear two, the opening and closing of the valve is directly controlled, achieving mechanical synchronization between the tilting action and the spraying from the tilting nozzle. This eliminates the problem of spraying being turned on too early or too late in manual operation, avoids waste of abrasive, and ensures that the grinding balls are rinsed in the first instance, preventing the TC4 titanium alloy powder from drying and caking. This improves the clean recovery rate of the grinding balls and the grinding quality of subsequent batches. At the same time, the linked nitrogen protection vent automatically maintains an inert atmosphere when the centrifuge is working, avoiding safety hazards caused by operational negligence and improving the inherent safety level and operational economy of the entire recovery process.

[0019] This invention utilizes a rotating shaft to drive a three-pronged gear rack in reciprocating motion, which in turn causes the striking blocks to rhythmically strike the filter basket. This effectively loosens the fine powder that is stubbornly attached to the gaps between the grinding balls and the pores of the filter screen due to high adhesion or static electricity, making it easier for the powder to fall off under the impact of the synchronous spray water flow. This solves the problems of incomplete grinding ball recovery and easy filter screen clogging caused by traditional rinsing methods, ensuring long-term filter screen patency and filtration efficiency, maximizing the total recovery rate of TC4 titanium alloy powder, and reducing the frequency of equipment maintenance.

[0020] This invention constructs a highly efficient slurry collection and conveying system through inclined plates, conveying pipes, and auxiliary flushing provided by vertical nozzles. This ensures that the separated powder slurry is introduced into the centrifuge without residue. The separated liquid abrasive is pumped into a water-based abrasive turnover tank via a pump body and transmission pipe, and can be circulated to the spraying system, forming a closed-loop circulation of the abrasive. This reduces consumable costs and the burden of waste liquid treatment. The entire process, from pouring, cleaning, conveying to separation, achieves a high degree of mechanization and continuity, reduces reliance on human experience, and ensures the stability and repeatability of batch processing quality.

[0030] 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.

[0031] Please see Figures 1 to 8 As shown, the present invention provides a technical solution: a feeding mechanism for preparing TC4 titanium alloy powder, comprising a feeding cart 1, with movable wheels 2 installed at the bottom of the feeding cart 1, a receiving frame 3 fixedly installed on the left side of the upper surface of the feeding cart 1, a drive motor 4 fixedly installed on the left side of the receiving frame 3, a drive shaft 5 fixedly installed at one end of the output shaft of the drive motor 4, the outer surface of the drive shaft 5 being rotatably connected to the inner wall of the receiving frame 3, a filter basket 6 installed at one end of the drive shaft 5, and a filter screen 7 provided at the bottom of the filter basket 6. An inclined plate 19 is installed inside the material handling trolley 1, and the inclined plate 19 is installed at the bottom of the material handling trolley 1. A synchronous tilting spray mechanism is installed on the right side of the upper surface of the material handling trolley 1. A tapping mechanism is installed at the output end of the synchronous tilting spray mechanism. The synchronous tilting spray mechanism includes a receiving frame 2 8, a rotating shaft 9, a gear 1 10, a gear 2 11, an extension plate 12, a water tank 13, a valve 14, a control rod 15, and a connecting water pipe 16. The lower surface of the receiving frame 2 8 is fixedly installed to the right side of the upper surface of the material handling trolley 1, and the outer surface of the rotating shaft 9 is fixed to the receiving frame 2 8. The inner wall of the second gear 8 is rotatably connected. The inside of gear 10 is fixedly installed with the outer surface of one end of the rotating shaft 9. The outer surface of gear 2 11 meshes with the outer surface of gear 10. The left side of the extension plate 12 is fixedly installed with the right side of the unloading cart 1. The bottom of the water tank 13 is fixedly installed with the upper surface of the extension plate 12. The water inlet end of the valve 14 is fixedly installed with the inside of the water tank 13. The inside of the control rod 15 is connected to the inside of the valve 14. The inside of gear 2 11 is fixedly installed with the outer surface of one end of the control rod 15. One end of the rotating shaft 9 is connected with the right side of the filter basket 6. The valve 14 is fixedly installed on the side. A connecting water pipe 16 is installed at the outlet end of the valve 14. A receiving bucket 17 is installed at the outlet end of the connecting water pipe 16. Both sides of the receiving bucket 17 are fixedly connected to the right side of the drive shaft 5 and the left side of the receiving frame 2 8. An inclined nozzle 18 is installed on the lower surface of the receiving bucket 17. The inside of the gear 3 29 is fixedly installed to the outer surface of the rotating shaft 9. A connecting water pipe 21 is fixedly connected to the outlet end of the valve 14. A receiving bucket 22 is fixedly connected to the outlet end of the connecting water pipe 21.

[0032] Specifically, the mobile base consisting of the unloading cart 1, the moving wheels 2, and the receiving frame 3, in conjunction with the drive motor 4 driving the filter basket 6 via the drive shaft 5, achieves portable material transfer and controllable tilting. The core feature is that the filter basket 6 is rigidly connected to the synchronous tilting spray mechanism via the rotating shaft 9, ensuring rigid synchronization between the tilting action and the spray opening and closing. When the filter basket 6 rotates and tilts, the rotating shaft 9 drives the gear 10 to rotate, which in turn drives the meshing gear 11 to rotate. The gear 11 directly controls the opening of the valve 14 via the control lever 15, allowing the abrasive in the water tank 13 to instantly flow into the receiving water bucket 17 via the connecting water pipe 16, and then be precisely sprayed onto the filter basket 6 by the tilting nozzle 18. This linkage eliminates manual labor. The time difference in operation ensures that the grinding balls are rinsed immediately after being poured out, avoiding waste of abrasive and preventing powder agglomeration, thus improving the recovery rate and the cleanliness of the grinding balls. At the same time, the rotating shaft 9 also drives the gear 3 29 to rotate, providing a power source for the subsequent tapping mechanism, realizing the synergy of cleaning and tapping under a single power source. In addition, by connecting water pipe 2 21, some of the abrasive is diverted to receiving water tank 2 22, providing an auxiliary rinsing source for subsequent slurry pipeline transportation and preventing powder deposition. The entire system structure is interlocked, seamlessly connecting multiple actions such as pouring, rinsing, tapping, and diversion supply in a purely mechanical manner, significantly improving the automation level of operation, process consistency, and processing efficiency.

[0033] according to Figure 1 , Figure 7 and Figure 8 As shown, the striking mechanism includes a gear 29, a limiting block 30, a rack 31, a connecting bar 32, and a striking block 33. The lower surface of the limiting block 30 is fixedly installed on the right side of the upper surface of the unloading cart 1. The outer surface of the rack 31 is rotatably connected to the inner wall of the limiting block 30. The outer surface of the gear 29 meshes with the upper surface of the rack 31. One side of the connecting bar 32 is fixedly installed on one side of the rack 31. One side of the striking block 33 is fixedly installed on the front side of the connecting bar 32.

[0034] Specifically, the striking mechanism, through the efficient coordination of its internal structure, brings a crucial deep cleaning effect to the TC4 powder recovery process. When the filter basket 6 is tilted, it drives the rotating shaft 9 to rotate, and the gear 29 fixed on it rotates accordingly. The gear 29 meshes with the upper surface of the rack 31, thereby converting the rotational motion into a precise horizontal reciprocating linear motion of the rack 31 within the limiting block 30. The limiting block 30 provides stable guidance and support for the rack 31, ensuring the stability of the motion trajectory. Then, the rack 31 transmits this reciprocating motion directly to the striking block 33 through the connecting strip 32, so that the striking block 33 periodically strikes the side wall or frame of the filter basket 6 with a certain frequency and force.

[0035] Furthermore, it achieves the conversion of the rotational kinetic energy of the main tilting action into mechanical vibration energy on the filter basket 6 without the need for an additional power source. The vibration wave generated by the striking block 33 is transmitted to the entire filter basket 6 and the grinding balls and filter screen 7 inside. This effectively loosens and peels off the fine TC4 powder that is difficult to remove by water flushing alone and is stubbornly attached due to high adhesion or static electricity. This improves the final cleanliness of the grinding balls, prevents cross-contamination, and alleviates the clogging problem of the filter screen 7, ensuring the long-term stability of filtration efficiency. As a result, the overall powder recovery rate and the continuity of system operation are improved.

[0036] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a conveying pipe 20 is fixedly installed on the right side inside the unloading cart 1. A vertical nozzle 23 is installed inside the conveying pipe 20. The water inlet of the vertical nozzle 23 is fixedly connected to the inside of the receiving bucket 22. A centrifuge 24 is installed at the water outlet of the conveying pipe 20. A nitrogen protective gas vent 25 is installed at the top of the centrifuge 24. A pump body 26 is installed at the bottom of the centrifuge 24. A transmission pipe 27 is fixedly installed at the water outlet of the pump body 26. A water-based abrasive turnover bucket 28 is fixedly installed at one end of the transmission pipe 27.

[0037] Specifically, the combination of the conveying pipe 20 and the vertical nozzle 23 constitutes an active slurry conveying channel. The abrasive introduced from the receiving tank 22 forms a downward or directional flushing water flow in the pipe through the vertical nozzle 23. This design ensures that the dense slurry, powder and liquid mixture entering from the inclined plate 19 can be effectively entrained and accelerated, and conveyed to the feed inlet of the centrifuge 24 without residue. This solves the problem of blockage and uneven conveying caused by the settling of powder in horizontal or inclined pipes, and ensures the continuity of the process.

[0038] Together with the centrifuge 24, nitrogen protective gas vent 25, pump body 26, transfer pipe 27, and water-based abrasive transfer tank 28, a safe closed-loop separation and recovery unit is formed. During centrifugation, the nitrogen protective gas vent 25 continuously injects inert gas into the centrifuge 24, maintaining a slightly positive pressure environment. This physically isolates oxygen, providing inherently safe operating conditions for the flammable and easily oxidized TC4 powder and preventing the risk of combustion and explosion. The separated liquid abrasive, after passing through a filter bag, is pumped entirely into the water-based abrasive transfer tank 28 via the transfer pipe 27 from the bottom pump body 26 for temporary storage. This design not only achieves complete solid-liquid separation but, more importantly, ensures the complete recovery of the used abrasive into a dedicated container.

[0039] The entire mechanism achieves the effect of synchronized material pouring and spraying: when the drive motor 4 starts, it drives the drive shaft 5 and the filter basket 6 fixed on it to rotate and pour the material. The rotating shaft 9, which is coaxially fixed with the filter basket 6, rotates synchronously. The rotating shaft 9 drives the gear 10 on it to rotate, and the gear 2 11 meshing with it rotates accordingly. The gear 2 11 is linked through the internal control rod 15 to open the valve 14 at the outlet of the water tank 13. The abrasive water-based medium then flows into the receiving water tank 17 through the connecting water pipe 16 and is sprayed out from the inclined nozzle 18 below it, realizing the immediate and synchronous rinsing of the abrasive balls in the filter basket 6 during pouring. This mechanical linkage ensures that the spraying and pouring actions are precisely synchronized. The rotation of the rotating shaft 9 also drives the gear 3 29 on it to rotate. The gear 3 29 drives the rack 31 meshing with it to make horizontal reciprocating motion within the limit block 30. The rack 31 drives the striking block 33 to periodically strike the filter basket 6 through the connecting bar 32. The mechanical vibration generated by the sidewalls or frame effectively loosens the fine TC4 powder stubbornly adhering to the surface of the grinding balls and the mesh of the filter screen 7, thereby allowing it to pass through the tilted nozzle 18. The slurry, powder, and abrasive mixture are thoroughly removed by the spray water flow. The washed-off slurry, powder, and abrasive mixture passes through the filter screen 7, is collected by the inclined plate 19 inside the unloading cart 1, and is guided through the conveying pipe 20. At the same time, some abrasive is diverted through the connecting water pipe 21 to the receiving water tank 22, and sprayed into the conveying pipe 20 by the vertical nozzle 23 connected to it, forming a horizontal auxiliary flushing to ensure that the slurry is smoothly flushed into the inlet of the centrifuge 24 and to prevent the powder from depositing in the pipe. After the slurry enters the centrifuge 24, solid-liquid separation is carried out under the slightly positive pressure inert atmosphere maintained by the nitrogen protective gas vent 25. The powder is trapped in the polypropylene filter bag inside the machine, and the liquid abrasive passes through the filter bag and is pumped by the pump body 26 at the bottom through the transmission pipe 27 into the water-based abrasive turnover tank 28 for temporary storage. It can be circulated back to the water tank 13 for reuse by the spraying system.

[0040] In this device, the drive motor 4 can be a miniature geared motor with variable frequency speed regulation, such as a servo motor of model 80ST-M02430. It is connected to the motor driver in the control cabinet via a cable and is supplied with industrial three-phase 380V AC power after voltage and frequency regulation by a frequency converter to achieve precise control of the tilting speed and angle of the filter basket 6. The valve 14 is a normally closed electric ball valve, such as an electric stainless steel ball valve of model Q911F-16P. Its built-in 24V DC miniature motor is connected to the DC power module in the same control cabinet via a control line. It receives electrical signals from the synchronous sensor of the drive motor 4 spindle or the position encoder coaxial with gear 10. Thus, at the moment when the mechanically linked gear 11 starts to rotate, the electrical signal triggers its electric actuator to synchronously rotate the valve core to the open position. The pump body 26 is a corrosion-resistant magnetically driven centrifugal pump, such as a fluoroplastic magnetic pump of model CQB32-20-145, supplied with three-phase 380V AC power. The system is directly driven by current, and its start and stop are controlled by an independent liquid level sensor or time relay circuit. When the liquid collection tank at the bottom of the centrifuge 24 reaches the set liquid level, the sensor signal starts the pump body 26 to pump the abrasive to the water-based abrasive transfer tank 28. The electrical energy of the entire system is uniformly distributed through the main power line connected to the control cabinet. The linkage operation of each actuator is driven by the drive motor 4: after the drive motor 4 is started, its mechanical output drives the filter basket 6 to rotate through the drive shaft 5, and through the mechanical rotation of the rotating shaft 9 and gear 10, it directly drives gear 21 to rotate in a mechanical manner to prepare to open the valve 14, and at the same time generates an electrical signal command. The circuit ensures that the electronic actuator of the electric valve 14 and the mechanical movement open precisely and synchronously to achieve spraying. At the same time, the gear 39 driven by the rotating shaft 9 and the rack 31 rely entirely on mechanical linkage to achieve tapping. The transfer of the separated liquid is completed by the pump body 26 controlled by an independent circuit based on the liquid level signal.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
