Description

Technical Field

[0001] This application relates to the field of titanium powder processing equipment technology, and in particular to a high-efficiency spraying device for titanium powder surface treatment. Background Technology

[0002] Surface treatment is a crucial step in the production and application of titanium powder. Surface treatment improves the performance of titanium powder and enhances its applicability in various fields.

[0003] Traditional titanium powder surface treatment methods have several shortcomings. In the feeding stage, common feeding methods struggle to ensure a stable and uniform entry of titanium powder into the processing unit, easily leading to fluctuating feed rates and affecting the stability of subsequent processing steps. For example, some gravity-feed devices rely solely on the titanium powder's own weight; when the powder's accumulation state changes, the feed rate fluctuates. During the spraying process, ordinary spraying equipment struggles to achieve uniform spraying of titanium powder. On one hand, due to the fine size and unique flow characteristics of titanium powder particles, it easily accumulates or distributes unevenly within the spraying chamber, preventing some powder from being fully and uniformly sprayed, resulting in inconsistent product quality. On the other hand, existing spraying component designs are inadequate; a single spray often fails to achieve ideal coverage, and secondary sprays are difficult to coordinate effectively with the primary spray, further reducing the quality and efficiency of surface treatment. Simultaneously, traditional stirring mechanisms suffer from insufficient stirring force and uneven mixing when agitating the titanium powder to promote uniform spraying. Ordinary stirring devices cannot fully tumble and disperse titanium powder during the spraying process, resulting in uneven spraying of titanium powder. This not only wastes spraying materials but also seriously affects the consistency and quality stability of the product.

[0004] Therefore, a high-efficiency spraying device for titanium powder surface treatment is invented to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency spraying device for titanium powder surface treatment, so as to solve the problems of unstable feeding, uneven spraying, poor stirring effect and unsmooth discharge in the existing technology during the titanium powder surface treatment process.

[0009] The spraying chamber is connected to the feeding mechanism and fixed on the fixed frame. It is used to contain titanium powder and perform spraying treatment. The spraying chamber is equipped with a spraying component, which can uniformly spray the titanium powder.

[0010] A vibration stirring mechanism is installed in the spraying chamber. The vibration stirring mechanism is used to stir the titanium powder so that the titanium powder can be sprayed evenly during the spraying process.

[0011] The discharge port is located at the bottom of the spraying chamber and is used to output the titanium powder that has undergone surface treatment.

[0012] Optionally, the feeding mechanism includes an inclined feeding hopper, the upper opening of which is the feeding port, and the lower end of which is connected to the spraying chamber.

Therefore, they should not be construed as limitations on the present utility model.

[0027] Reference Figure 1 , Figure 3 One embodiment shown is as follows: The fixed frame 1 provides a stable support foundation for the entire device. The feeding mechanism 2 is located on top of the fixed frame 1, allowing titanium powder to smoothly enter the spraying chamber 4 from the feeding hopper 8 for subsequent processing. The spraying chamber 4 is fixed to the fixed frame 1, and its connection to the feeding mechanism 2 is via a pipe. This connection design ensures that the titanium powder can be smoothly transferred from the feeding mechanism 2 to the spraying chamber 4. A spraying assembly 5 is installed inside the spraying chamber 4 for uniformly spraying the titanium powder. A vibration stirring mechanism 6 is installed inside the spraying chamber 4, generating up-and-down vibrations to stir the titanium powder, ensuring uniform spraying during the spraying process. The discharge port 7 is located at the bottom of the spraying chamber 4. In this embodiment, the discharge port 7 can be a valved discharge port 7. After the titanium powder has undergone surface treatment, the valve is opened, and the titanium powder is output from the discharge port 7 under gravity.

[0028] The implementation principle of the above embodiment is as follows: The fixing frame 1 first provides stable support for the entire device, enabling each component to be installed and operate normally. Titanium powder enters from the feed inlet 3 and moves towards the lower end, which is connected to the spraying chamber 4, under the guidance of the feed hopper 8. After entering the spraying chamber 4, the spraying component 5 begins to spray the titanium powder, while the vibration stirring mechanism 6 stirs the titanium powder to ensure uniform distribution, facilitating uniform spraying by the spraying component 5. The processed titanium powder is then output from the discharge port 7 at the bottom of the spraying chamber 4 under the action of gravity.

[0029] Reference Figure 3 One embodiment shown is as follows: The feeding mechanism 2 includes an inclined feeding hopper 8, with an upper opening of the feeding hopper 8 as a feeding port 3 for feeding titanium powder. The inclined arrangement of the feeding hopper 8 facilitates the smooth movement of the titanium powder towards the lower end, which communicates with the spraying chamber 4, under the action of gravity and the spiral conveying rod 9. A spiral conveying rod 9 is installed inside the feeding hopper 8, and is mounted inside the feeding hopper 8 via rotating connecting components such as bearings, allowing the spiral conveying rod 9 to rotate freely within the feeding hopper 8. In this embodiment, a drive motor 10 is installed at the top of the feeding mechanism 2, and the drive motor 10 is fixed to the top of the feeding mechanism 2 via components such as a motor mounting bracket. This fixing method ensures the stability of the drive motor 10 during operation. The output end of the drive motor 10 is fixedly connected to the spiral conveying rod 9, for example, through a coupling, ensuring that the power of the drive motor 10 can be stably transmitted to the spiral conveying rod 9, driving the spiral conveying rod 9 to rotate.

[0030] The implementation principle of the above embodiment is as follows: After the drive motor 10 starts, its output end drives the screw conveyor 9 to rotate inside the feed hopper 8. Due to the special structure of the screw conveyor 9, when it rotates, it pushes the titanium powder in the feed hopper 8 to move along the inclined direction of the feed hopper 8 towards the lower end that is connected to the spraying chamber 4, thereby stably conveying the titanium powder to the spraying chamber 4, realizing the function of stable feeding and avoiding fluctuations in the feed amount.

[0031] Reference Figure 4 , Figure 5 One embodiment shown is as follows: The vibrating stirring mechanism 6 includes a vibrating plate 11, which is located inside the spraying chamber 4, directly below the connection between the feeding mechanism 2 and the spraying chamber 4. A vibrating motor 12 is installed at the bottom of the vibrating plate 11, and the vibrating motor 12 is fixed to the bottom of the vibrating plate 11 by bolts or other fastening components. This fixing method ensures that the vibrating motor 12 is tightly connected to the vibrating plate 11 during operation, and can transmit its generated vibration to the vibrating plate 11. Several connecting springs 13 are provided between the vibrating plate 11 and the spraying chamber 4. In this embodiment, one end of the connecting spring 13 is fixed to a specific position on the bottom of the vibrating plate 11 by welding or bolting, and the other end is also fixed to the bottom or side of the spraying chamber 4. Through the elastic connection of the connecting springs 13, the vibrating plate 11 can vibrate up and down under the drive of the vibrating motor 12.

[0032] The implementation principle of the above embodiment is as follows: After the vibration motor 12 is started, the vibration generated is transmitted to the vibration disk 11 through a fixed connection with the bottom of the vibration disk 11. Since the vibration disk 11 is elastically connected to the spraying chamber 4 through the connecting compression spring 13, the vibration disk 11 can vibrate up and down in the spraying chamber 4 under the action of the vibration motor 12, thereby stirring the titanium powder located on or around the vibration disk 11, so that the titanium powder continuously rolls during the spraying process, achieving a uniform spraying effect.

[0033] Reference Figure 3 , Figure 4 , Figure 5One embodiment is shown as follows: A stirring shaft 15 is provided at the bottom of the guide block 14. The guide block 14 and the stirring shaft 15 are connected by welding or other fastening methods to ensure that the guide block 14 and the stirring shaft 15 can move synchronously. A sliding rod 16 that can slide up and down is provided at the bottom of the stirring shaft 15. The stirring shaft 15 and the sliding rod 16 are slidably connected, and the sliding rod 16 can slide up and down along the axial direction at the bottom of the stirring shaft 15. The bottom of the sliding rod 16 is in contact with the vibratory plate 11. A return spring 17 is fitted on the sliding rod 16. One end of the return spring 17 is fixed to the sliding rod 16, for example, by a hook or a clip, and the other end is fixed to the stirring shaft 15. Two stirring rods 18 are provided on the sliding rod 16. The stirring rods 18 are fixed to the sliding rod 16 by welding or bolting. When the sliding rod 16 moves, the stirring rods 18 move accordingly. When the stirring rods 18 rotate, they can push the titanium powder from the vibratory plate 11 into the spraying chamber 4.

[0034] The implementation principle of the above embodiment is as follows: When the vibratory plate 11 vibrates under the action of the vibratory motor 12, it drives the guide block 14 and the stirring shaft 15 connected thereto to vibrate. Due to the sliding connection between the sliding rod 16 and the stirring shaft 15 and the action of the return spring 17, the sliding rod 16 will slide up and down during the vibration process, while the stirring shaft 15 drives the stirring rod 18 to rotate. During the rotation of the stirring rod 18, the titanium powder in the vibratory plate 11 is pushed into the spraying chamber 4, and during the up and down sliding of the sliding rod 16, the stirring and pushing effect of the stirring rod 18 on the titanium powder is more diversified, further promoting the uniform dispersion and spraying of the titanium powder.

[0035] Reference Figure 3 , Figure 4 , Figure 5 One embodiment shown is as follows: The spraying assembly 5 includes a primary spraying structure 19. A guide block 14 is provided at the bottom of the spiral conveyor 9. The spiral conveyor 9 and the guide block 14 are fixed together by welding or threaded connection. The guide block 14 disperses the titanium powder output from the spiral conveyor 9, changing the concentration state of the titanium powder and making it more conducive to spraying. Multiple primary nozzles 20 are evenly distributed on the periphery of the guide block 14. The primary nozzles 20 are connected to an external spraying material supply system through pipe connections and fasteners, and are fixed to the periphery of the guide block 14 by mounting brackets and other components to ensure that the primary nozzles 20 can stably spray the dispersed titanium powder in one pass. The spraying assembly 5 also includes a secondary spraying structure 21, which includes a secondary nozzle 22. The secondary nozzle 22 is uniformly fixed on the periphery of the vibratory plate 11. In this embodiment, the secondary nozzle 22 is fixed at a specific position on the periphery of the vibratory plate 11 by means of welding or bolt connection, and is connected to an external spraying material supply system through a pipeline for secondary spraying of titanium powder after primary spraying and vibration stirring.

[0036] The implementation principle of the above embodiment is as follows: Titanium powder is conveyed to the guide block 14 via the spiral conveyor 9. After the guide block 14 disperses the titanium powder, the primary spray head 20 performs a primary spraying on the dispersed titanium powder. Subsequently, the titanium powder is further dispersed under the vibration and stirring action of the vibrating plate 11 and is pushed into the spraying chamber 4. At this time, the secondary spray head 22 located on the periphery of the vibrating plate 11 performs a secondary spraying on the titanium powder. Through the combination of primary and secondary spraying, the uniformity and coverage of the spraying are greatly improved, thus enhancing the quality of the titanium powder surface treatment.

[0037] The working principle of this device is as follows: Titanium powder enters through the feed inlet 3 at the top opening of the feed hopper 8. The feed hopper 8 is inclined, and the internal spiral conveyor rod 9 rotates under the drive of the top drive motor 10. The output end of the drive motor 10 is securely connected to the spiral conveyor rod 9 via a coupling to ensure power transmission. When the spiral conveyor rod 9 rotates, its spiral structure pushes the titanium powder, overcoming gravity, along the feed hopper 8 towards the lower end connected to the spraying chamber 4, stably conveying it to the spraying chamber 4 and avoiding fluctuations in the feed rate.

[0038] Primary spraying: The titanium powder arriving at the spraying chamber 4 is first dispersed by the guide block 14 at the bottom of the spiral conveyor 9, changing its concentrated state. The guide block 14 is fixedly connected to the spiral conveyor 9, and the dispersed titanium powder is then sprayed by the primary spray nozzles 20 evenly distributed around the guide block 14. The primary spray nozzles 20 are connected to an external spraying material supply system through pipes to stably spray the coating, completing the initial coating.

[0039] Secondary spraying: Simultaneously, the vibrating mixing mechanism 6 operates. The vibration motor 12 at the bottom of the vibrating plate 11 starts, and is fastened to the vibrating plate 11 by bolts, etc. The generated vibration is transmitted to the vibrating plate 11 through the connecting spring 13, causing the vibrating plate 11 to vibrate up and down. The titanium powder on or around the vibrating plate 11 tumbles accordingly, and is further dispersed in conjunction with the mixing shaft 15, sliding rod 16, and mixing rod 18. The sliding rod 16 at the bottom of the mixing shaft 15 can slide up and down, and is connected to the mixing shaft 15 by the return spring 17. The mixing rod 18 on the sliding rod 16 pushes the titanium powder off the vibrating plate 11 when it rotates. The secondary spray head 22, which is evenly fixed around the vibrating plate 11, performs a secondary spraying of the titanium powder, improving the uniformity of the spraying and the coverage effect.

[0040] Material discharge stage: The titanium powder that has completed surface treatment is discharged from the discharge port 7 at the bottom of the spraying chamber 4 under the action of gravity.

[0041] The working principle of this device has been explained through the above embodiments.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
