Description

Technical Field

[0001] This application relates to the field of mixing equipment technology, specifically a mixing equipment for polishing powder and additives. Background Technology

[0002] Rare earth polishing powder, with cerium oxide as its main component, is characterized by strong chemical activity and grinding ability, which can significantly improve polishing efficiency. It offers high polishing quality, uniform particle size, moderate hardness, and a smooth, uniform surface after polishing, making it particularly suitable for high-precision applications such as precision optical instruments and semiconductor components. However, during the processing of rare earth polishing powder, additives need to be added to prevent particle agglomeration, ensure uniform dispersion, avoid fluctuations in polishing effect due to sedimentation, and extend the service life of the polishing slurry. This requires the use of mixing equipment.

[0003] Chinese patent discloses a mixing device for polishing powder and powder additives (authorization announcement number CN215138853U). This patented technology includes a housing and a base groove. A drive belt is installed inside the housing, and a driven wheel is connected to the inner surface of the drive belt. A drive wheel is located to the left of the driven wheel, and a drive shaft is fixed to the bottom of the drive wheel. A drive motor is mounted to the bottom of the drive shaft, and a movable plate is mounted to the bottom of the drive motor. A base plate is fixed to the left side of the movable plate, and the base groove is connected to the outer surface of the base plate. A support is located on the outer side of the base groove, and a base is located at the bottom of the support. A fixing roller is located at the bottom of a fixing pin. This mixing device for polishing powder and powder additives, equipped with a drive motor, drive shaft, drive wheel, drive belt, and driven wheel, can easily provide power to the scraper that needs to be stirred, facilitating thorough mixing of the materials without manual stirring, simplifying operation, and improving mixing results.

[0004] However, it cannot be added and mixed in a closed system; when a large amount of material is mixed at once, it may lead to mixing difficulties and uneven mixing, resulting in poor performance of the polishing powder. Utility Model Content

[0005] The purpose of this invention is to provide a mixing device for polishing powder and additives to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mixing device for polishing powder and additives includes a base and two columns, one and two, respectively fixed on the upper sides of the base. A V-shaped mixing tank is installed between the two columns. One end of the V-shaped mixing tank is connected to a feed pipe, and the other end is connected to a feeding pipe. One end of the feed pipe is rotatably connected to the feed pipe, and one end of the feeding pipe is rotatably connected to the feed pipe, the other end of the feeding pipe. A motor is installed at one end of the feeding pipe. The output end of the motor is located inside the feeding pipes and is equipped with an auger. A feeding port is connected to the upper end of the feeding pipe near the motor. A driven gear is installed on the outer side of the feeding pipe near the rotary joint. A motor is installed on the outer side of the column, near the lower end of the feeding pipe. The output end of the motor is fixedly connected to a connecting shaft inside the column. A driving gear is installed on the connecting shaft, and the driving gear meshes with the driven gear.

[0008] As a further embodiment of this utility model: a bearing is installed at the junction of the feed pipe 2 and the column 1, and the feed pipe 1 is fixedly installed on the column 1.

[0009] As a further improvement of this utility model, bearings are embedded and installed at both ends of the junction between the connecting shaft and the second column.

[0010] As a further embodiment of this utility model: a bearing three is installed at the junction of the second feeding pipe and the second column, while the first feeding pipe is fixedly installed on the second column.

[0011] As a further embodiment of this utility model: a motor is installed on both sides of the upper end of the V-shaped mixing barrel, the output end of the motor is fixedly connected to a stirring shaft inside the V-shaped mixing barrel, a stirring blade is fixedly connected to the lower end of the stirring shaft, and a battery is installed on the top of the motor.

[0012] As a further improvement of this utility model: the bottom of the V-shaped mixing barrel is provided with a discharge port, and a discharge valve is installed on the discharge port.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention allows rare earth polishing powder to be added into a feeding pipe through a feeding port. A second motor drives an auger to rotate, allowing the polishing powder to enter a V-shaped mixing tank. An additive is pumped in through a first feeding pipe, passing through a second feeding pipe before entering the V-shaped mixing tank. A third motor, connecting shaft, drive gear, and driven gear enable the second feeding pipe, the V-shaped mixing tank, and the second feeding pipe to rotate together. During rotation, the additive and polishing powder are mixed. While the V-shaped mixing tank is rotating, additives and polishing powder can still be continuously added through the first feeding pipe and the feeding port. Therefore, simultaneous feeding and mixing effectively ensures the uniformity of the mixture. Simultaneously, the first motor drives the stirring shaft and stirring blades to rotate, further improving the mixing effect by agitating the contents of the V-shaped mixing tank during rotation.

[0021] Please see Figures 1-5In this embodiment of the present invention, a mixing device for polishing powder and additives includes a base 2, and two columns 1 and 3 respectively fixed on the upper sides of the base 2. A V-shaped mixing tank 4 is installed between the two columns 1 and 3. The bottom of the V-shaped mixing tank 4 is provided with a discharge port 8. A discharge valve 7 is installed on the discharge port 8. When the discharge port 8 is facing downward, the discharge valve 7 is opened, and the mixed polishing powder and additives can be discharged from the discharge port 8.

[0022] exist Figure 2 and Figure 3 In this process, one end of the second feeding pipe 22 is rotatably connected to the first feeding pipe 16 via the second rotary joint 24. A second motor 15 is installed at one end of the first feeding pipe 16. The output end of the second motor 15 is located inside both the first feeding pipe 16 and the second feeding pipe 22, where an auger 26 is installed. A feeding port 25 is connected to the upper end of the first feeding pipe 16 near the second motor 15. Rare earth polishing powder can be added into the first feeding pipe 16 through the feeding port 25. The second motor 15 then drives the auger 26 to rotate, causing the polishing powder in the first feeding pipe 16 to pass sequentially through the second rotary joint 24 and the second feeding pipe 22. After 22, it enters the V-shaped mixing tank 4; both ends of the junction of the connecting shaft 19 and the column 2 3 are embedded with bearing 2 18, which can ensure that the connecting shaft 19 rotates stably inside the bearing 2 18, thereby realizing the smoothness of the meshing transmission between the driving gear 20 and the driven gear 23. The junction of the feeding pipe 22 and the column 2 3 is equipped with bearing 3 21, while the feeding pipe 1 16 is fixedly installed on the column 2 3. Therefore, the feeding pipe 22 can rotate stably at the rotary joint 24 with bearing 3 21 as the center, while the feeding pipe 1 16 remains fixed.

[0023] exist Figure 2 and Figure 4 In the V-shaped mixing tank 4, one end is connected to the feed pipe 210, and the other end is connected to the feeding pipe 22. One end of the feed pipe 210 is rotatably connected to the feed pipe 9 via the rotary joint 12. A bearing 11 is installed at the junction of the feed pipe 210 and the column 1, while the feed pipe 9 is fixedly installed on the column 1. Therefore, the feed pipe 210 can rotate stably at the rotary joint 12 with the bearing 11 as the center, while the feed pipe 9 remains fixed. The additive can be pumped in from the feed pipe 9. The additive enters the V-shaped mixing tank 4 after passing through the rotary joint 12 and the feed pipe 210 in sequence.

[0024] exist Figure 2 and Figure 3In this system, a driven gear 23 is installed on the outer side of the second feeding pipe 22 near the rotary joint 24, and a motor 3 17 is installed on the outer side of the second column 3 near the lower end of the first feeding pipe 16. The output end of the motor 3 17 is fixedly connected to a connecting shaft 19 inside the second column 3. A drive gear 20 is installed on the connecting shaft 19, and the drive gear 20 meshes with the driven gear 23. When the additives and polishing powder are added into the V-shaped mixing tank 4, the motor 3 17 drives the connecting shaft 19 and the drive gear 20 to rotate. The drive gear 20 meshes with the driven gear 23, causing the second feeding pipe 22, the V-shaped mixing tank 4, and the second feeding pipe 10 to rotate together. During the rotation of the V-shaped mixing tank 4, the additives and polishing powder are mixed. While the V-shaped mixing tank 4 is rotating, additives and polishing powder can still be continuously added from the first feeding pipe 9 and the feeding port 25. Therefore, it is possible to add materials and mix them simultaneously, effectively ensuring the uniformity of the mixture.

[0025] exist Figure 2 and Figure 5 In the V-shaped mixing tank 4, motors 5 are installed on both sides of the upper end. The output end of motor 5 is located inside the V-shaped mixing tank 4 and is fixedly connected to a stirring shaft 14. The lower end of the stirring shaft 14 is fixedly connected to a stirring blade 13. A battery 6 is installed on the top of motor 5, which can supply power to motor 5. Motor 5 drives stirring shaft 14 and stirring blade 13 to rotate together. Stirring blade 13 further stirs and mixes the polishing powder and additives in the V-shaped mixing tank 4. Therefore, during the rotation of V-shaped mixing tank 4, stirring blade 13 can still be used to stir the contents of V-shaped mixing tank 4, further improving the mixing effect.
