Description

Technical Field

[0001] The present invention relates to the technical field of diamond micropowder purification, in particular to a purification device and method for removing impurities from diamond micropowder by a chemical method. Background Art

[0002] Diamond powder, a key superhard material, holds an irreplaceable position in precision grinding, polishing, and cutting due to its exceptional hardness, excellent wear resistance, and good chemical stability. In semiconductor manufacturing, it is used to polish silicon wafers and silicon wafers to achieve atomically flat surfaces, ensuring the precision of chip manufacturing processes. In optical glass processing, diamond powder enables high-precision grinding of lens and display glass, enhancing their optical performance. In the gemstone processing industry, it enables the precise cutting and polishing of precious gemstones such as diamonds and rubies, revealing their brilliance.

[0003] However, diamond powder has an extremely small particle size, typically at the micron or even submicron level, which gives it a large specific surface area. This characteristic significantly enhances the van der Waals forces between the particles, causing the powders to easily attract and aggregate, ultimately forming flaky agglomerates. This agglomeration phenomenon severely impacts the efficiency of chemical impurity removal. Simply impinging the diamond powder within the net bag with a solution is ineffective in effectively dispersing the agglomerates. Consequently, impurities within the powder are unable to fully contact the chemical solution, leading to incomplete reaction and residual impurities. Furthermore, this impurity removal method has another drawback. During the impurity removal process, clumps of diamond powder can easily become lodged in the corners or pores of the net bag. The edges and complex structure of the net bag weaken the flushing force of the solution, making it difficult to loosen the trapped powder and preventing the timely removal of trapped impurities. These residual impurities not only reduce the purity of the diamond powder but may also affect its performance during subsequent use. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem existing in the prior art. However, the particle size of diamond micropowder is extremely small, usually at the micron or even submicron level, which gives it a huge specific surface area. Based on this characteristic, the van der Waals force between the particles is significantly enhanced, causing the micropowder to easily attract each other and aggregate, eventually forming flaky agglomerates. This agglomeration phenomenon seriously affects the efficiency of chemical impurity removal. It is difficult to effectively disperse the agglomerates by relying solely on the solution impacting the diamond micropowder in the net bag, resulting in the impurities inside the micropowder unable to fully contact the chemical solution, causing problems such as insufficient reaction and impurity residue. In addition, the solution impact impurity removal method has another disadvantage. During the impact process, the accumulated diamond micropowder is easily embedded in the corners or pores of the net bag. The edges and complex structure of the net bag will weaken the scouring force of the solution, making it difficult for the trapped micropowder to loosen, and the impurities wrapped therein cannot be discharged in time. These residual impurities not only reduce the purity of the diamond micropowder, but may also affect its performance in subsequent use. A purification device and method for chemical impurity removal of diamond micropowder is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The cam is fixedly mounted on the support frame and is provided with a first end fixed to the support frame, and the second end of the cam is fixedly mounted on the support frame, wherein the first end is connected to the support frame by a first rotating shaft and a second rotating shaft is connected to the support frame by a second rotating shaft.

[0007] The above technical solution further includes:

[0008] A motor is fixedly connected to the side of the support frame, and the output end of the motor is fixedly connected to the second bevel gear. The short rod is transmission-connected to a secondary belt, and the end of the secondary belt away from the short rod is transmission-connected to a connecting column, and the connecting column is transmission-connected to a transmission belt, and the end of the transmission belt away from the connecting column passes through the positioning plate and is transmission-connected to a cam.

[0009] A block is fixedly connected to the side of the support frame, one end of which is used to support the connecting column. This ensures the rotation stability of the connecting column, ensures the stable operation of the transmission structure, provides reliable support for the rotation of components such as the cam, and maintains the continuity of the device's transmission system.

[0010] The extension rod is slidably connected to a splash plate, which is threadedly connected to a debris removal box. The position of the splash plate can be flexibly adjusted to prevent splashing of the solution during impact, thereby improving operational safety and a clean working environment.

[0011] The surface of the placement box is provided with multiple groups of holes for filtering impurities, achieving solid-liquid separation, facilitating the reaction of the solution with the diamond micropowder impurities through the holes, and intercepting the micropowder to ensure the smooth progress of the purification process.

[0012] The impurity removal box is fixedly connected to a bottom leg, and a valve for releasing the solution is provided below the box. The bottom leg enhances the stability of the impurity removal box, and the valve facilitates the controlled release of the solution, facilitating the discharge and replacement of the solution after the reaction, thus facilitating the purification operation.

[0013] A fixed L-shaped plate is fixedly connected to the side of the support frame.

[0014] The fixed track is fixedly connected to the support frame, providing precise sliding guides for components such as the slide block, ensuring the accuracy and stability of the up and down sliding of components such as the debris removal box.

[0015] An auxiliary block for supporting the rotation of the short rod is fixedly connected to the side of the support frame, ensuring smooth rotation of the short rod, ensuring the stability of the transmission system, and ensuring stable and efficient power transmission between various components.

[0016] The present invention has the following beneficial effects:

[0017] 1. In this invention, a motor-driven cam, rotating bar, and other components work in tandem. The impurity removal box drives the solution upward and downward, impacting the diamond powder. It also intermittently drives the storage box upward, impacting aggregated diamond powder. These two combined actions effectively break down diamond powder agglomerates, increasing the contact area between the powder and the chemical solution. This promotes a full chemical reaction between the chemical solution and impurities, converting them more quickly and thoroughly into easily removable substances. This significantly improves impurity removal efficiency and ensures the purity of the diamond powder.

[0018] 2. In the present invention, the vibration design of the placement box and the up and down impact of the solution in the device can effectively prevent the diamond micropowder from accumulating in the corners of the mesh bag. When the placement box is driven to impact upward, the position of the micropowder in the mesh bag constantly changes, reducing the situation where the micropowder is stuck in the corners of the mesh bag and forming accumulations, so that impurities can be discharged in time under the action of the solution, avoiding the problem of impurity residues caused by micropowder accumulation, and further improving the purification quality of diamond micropowder.

This ensures that the short rod 22 rotates smoothly, ensures the stability of the transmission system, and ensures stable and efficient power transmission between various components.

[0040] The working principle of the purification device and method for removing impurities from diamond micropowder by a chemical method in the present invention is as follows: first, the diamond micropowder to be removed of impurities is poured into the placement box 18, and then the thread at the opening of the placement box 18 is threadedly connected to the threaded cover plate 17, so that it is fixed to the bottom of the threaded cover plate 17, and then the impurity removal box 8 with the solution is fixed to the side of the connecting block 7, and then the splash plate 26 is slid down and threadedly connected to the opening of the impurity removal box 8. At this time, the motor 25 is started to rotate, and the rotation of the output end of the motor 25 drives the second bevel gear 24 to further penetrate the support frame 1 and drive one end of the first rotating bar 3 to rotate, and the second bevel gear 24 is driven to rotate. The first rotating bar 3 performs a circular motion, thereby driving one end of the second rotating bar 4 to slide up and down. The rotation of the first rotating bar 3 rotates in the large opening at the bottom of the support frame 1. The end of the second rotating bar 4, close to the sliding block 6, reciprocates up and down with the rotation of the first rotating bar 3. The sliding block 6 connected to the rotation of the second rotating bar 4 slides up and down. Then, the connecting block 7 fixed to the side of the sliding block 6 drives the impurity removal box 8 to slide up and down. After sliding up and down, the liquid inside the impurity removal box 8 immediately impacts the diamond powder to be removed in the storage box 18. The chemical solution reacts with the impurities, converting them into substances that are easier to remove. For example, sodium carbonate solution can neutralize some acidic impurities to produce salt and water, reducing the adhesion of the impurities and making them easier to rinse away.

[0041] In addition, when the output end of the motor 25 drives the second bevel gear 24 to rotate, the second bevel gear 24 will mesh with the first bevel gear 23 to drive the short rod 22 to rotate, and the short rod 22 will use the secondary belt 27 to drive the connecting column 20 to rotate, and the connecting column 20 will use the transmission belt 19 to penetrate the positioning plate 15 to drive the cam 11 to rotate. The rotation of the cam 11 will intermittently use the convex and concave parts to cyclically squeeze the lower pressing piece 12. When the convex part of the cam 11 squeezes the lower pressing piece 12, the lower pressing piece 12 moves downward to squeeze the spring 14 to shorten the length. As the cam 11 continues to rotate, the cam 11 rotates to the concave part to squeeze the spring The compressed length of 14 becomes shorter, and at this time the spring 14 rebounds quickly to push the lower pressing plate 12 upward, and the sliding column 13 fixed at the bottom of the lower pressing plate 12 will intermittently slide downward, and then slide upward. When it is converted from the convex part of the cam 11 to the concave part, the rebound force of the spring 14 will quickly drive the sliding column 13 to slide upward and hit the concave part of the cam 11. At this time, the extension rod 16 fixed at the bottom of the sliding column 13 will quickly move upward at a speed that will drive the placement box 18 to impact upward, and the diamond micropowder agglomerates to be treated placed inside the placement box 18 will shift their position, thereby increasing the reaction rate of the chemical solution and the diamond micropowder to be treated.
