[0002] Diamond micron powder refers to diamond particles with a particle size finer than 36 / 54 micrometers. It includes both single-crystal and polycrystalline diamond micron powder. Due to the large production volume and wide range of applications of single-crystal diamond micron powder, the industry generally refers specifically to single-crystal diamond micron powder. Single-crystal diamond micron powder is produced by hydrostatic pressing of synthetic single-crystal diamond abrasive grains, followed by crushing, shaping, and special processes for superhard materials. Diamond micron powder has high hardness and good wear resistance, and can be widely used in cutting, grinding, drilling, and polishing. It is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones, and optical glass. Diamond micron powder products are tools and components made using diamond micron powder processing.

[0014] Three beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This is applicable to the chemical removal of impurities from diamond micro powder. By setting up a sieving device, the diamond micro powder is placed on the outer surface of the second transparent mesh and enters the barrel for acid washing. This allows impurities in the diamond micro powder to remain on the surface of the second transparent mesh during the acid washing process, which facilitates the simultaneous sieving of the reactants during the acid washing of the diamond micro powder and improves the efficiency of the chemical removal of impurities from diamond.
[0017] 2. This is applicable to the chemical removal of impurities from diamond micron powder.

[0024] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a device for chemically removing impurities from diamond micron powder, comprising a barrel 1, a discharge pipe 7 disposed on one side of the bottom end of the barrel 1, a control valve disposed at the top end of the discharge pipe 7, a mechanical rod 4 fixedly connected to one side of the barrel 1, a servo motor 5 disposed at the top end of the mechanical rod 4, a lead screw 6 rotatably connected to the inner wall of the mechanical rod 4, the output end of the servo motor 5 being fixedly connected to the top end of the lead screw 6, a screening device 2 disposed on one side of the mechanical rod 4, the screening device 2 comprising a frame rod 21, one end of the frame rod 21 sliding on the inner wall of the mechanical rod 4, one end of the inner wall of the frame rod 21 being threadedly connected to the outer surface of the lead screw 6, and a drive valve disposed on one side of the frame rod 21. Motor 22, drive motor 22, has a stirring rod 23 fixedly connected to its output end. The top of stirring rod 23 rotates on the inner wall of frame rod 21. Two connecting rods 24 are fixedly connected to the bottom of frame rod 21. A first permeable mesh 25 and a second permeable mesh 26 are fixedly connected to the outer surface of connecting rod 24. The mesh size of the first permeable mesh 25 is smaller than that of the second permeable mesh 26. By setting the first permeable mesh 25 and the second permeable mesh 26, when chemically removing impurities from diamond powder, the servo motor 5 at the top of the operating rod 4 controls the lead screw 6 to rotate, causing one end of frame rod 21 to move up on the outer surface of lead screw 6 and slide up on the inner wall of rod 4, driving the first permeable mesh 25 on the surface of frame rod 21 to rotate. The first and second screens 25 and 26 rise, and diamond powder is then placed on the outer surface of the second screen 26. Acid for impurity removal is added to the inside of the tank 1. The servo motor 5 drives the lead screw 6 to rotate, and the control rod 21 descends to cover the top of the tank 1, allowing the diamond powder to contact the acid inside the tank 1 for acid washing. Simultaneously, the drive motor 22 at the top of the control rod 21 drives the stirring rod 23 to rotate, accelerating the reaction between the diamond and acid. Impurities generated during the reaction remain on the surface of the second screen 26, while smaller particles of reactant pass through the second screen 26 and enter the surface of the first screen 25, where they remain. After a period of time, acid washing is completed on the surface of the first transparent mesh 25. The operation of the drive motor 22 is stopped, and the servo motor 5 controls the support rod 21 to rise. The control valve at the top of the discharge pipe 7 is opened to discharge the liquid inside the barrel 1. The reactant material on the surface of the first transparent mesh 25 and the impurities on the surface of the second transparent mesh 26 are removed. By setting up the screening device 2, the diamond powder is placed on the outer surface of the second transparent mesh 26 and enters the barrel 1 for acid washing. The impurities in the diamond powder acid washing process remain on the surface of the second transparent mesh 26, which facilitates the screening of reactant material during the diamond powder acid washing process and improves the efficiency of chemical impurity removal of diamond.
[0026] Specifically, such as Figure 2-4As shown, a spur gear 27 is fixedly connected to the output end of the drive motor 22. A cylinder 28 is rotatably connected to the top of the inner wall of the support rod 21. A half gear 29 is fixedly connected to the outer surface of the cylinder 28. The spur gear 27 meshes with the half gear 29. A pressure plate 210 is slidably connected to the inner wall of the support rod 21. A screw 211 is fixedly connected to the top of the pressure plate 210. The outer surface of the screw 211 is threaded to the inner wall of the cylinder 28. A round block 212 is rotatably connected to the top of the screw 211. A spring 213 is provided at the top of the round block 212. The upper and lower ends of the spring 213 are fixedly connected to the top of the inner wall of the cylinder 28 and the top of the round block 212, respectively. When the drive motor 22 operates, it drives the spur gear 27 to rotate. When the spur gear 27 rotates and its outer surface meshes with the outer surface of the half gear 29, it drives the half gear 29 and the cylinder 28 to rotate. This causes the screw 211 to move upward on the inner wall of the cylinder 28 and compress the spring 213 at the top of the round block 212. The screw 211 drives the pressure plate 210 to rise inside the barrel 1. After the spur gear 27 moves away from the surface of the half gear 29, the spring 213 returns to its original state and pushes the screw 211 downward inside the cylinder 28. This causes the pressure plate 210 to move downward inside the barrel 1, generating downward pressure inside the barrel 1. This allows the reactant material on the surface of the second permeable mesh 26 to pass through the surface of the second permeable mesh 26 more quickly and enter the first permeable mesh 25, improving the efficiency of the screening device 2.
[0027] Specifically, such as Figure 2-4 As shown, a round rod 214 is fixedly connected to the top of the round block 212. The round rod 214 slides on the inner wall of the cylinder 28. When the screw 211 moves up and down, the round rod 214 will slide on the inner wall of the cylinder 28. The round rod 214 can further limit the angle between the screw 211 and the cylinder 28, so as to avoid the angle between the screw 211 and the cylinder 28 from being skewed and affecting the normal movement of the screw 211 or the rotation of the cylinder 28. The diameter of the round rod 214 is slightly smaller than the inner diameter of the spring 213. The spring 213 is located outside the round rod 214. When the screw 211 moves inside the cylinder 28 and causes the spring 213 to deform, the round rod 214 can reinforce the internal shape of the spring 213, so as to avoid the surfaces of different positions of the spring 213 from folding together when the spring 213 is deformed, thus affecting the normal use of the spring 213.
[0028] Specifically, such as Figure 1-4As shown, an auxiliary device 3 is provided at the top of the support rod 21. The auxiliary device 3 includes a push rod 31, the top of which is fixedly connected to the top of the cylinder 28. Two rectangular blocks 32 are fixedly connected to one side of the top of the support rod 21. The tops of the two rectangular blocks 32 are rotatably connected to a striking rod 33 via a rotating shaft. A coil spring 34 is provided at one end of the rotating shaft connecting the striking rod 33 and the rectangular blocks 32. The other end of the coil spring 34 is connected to one side of the rectangular blocks 32. When the half gear 29 and the cylinder 28 are rotated by the flat gear 27, one end of the push rod 31 pushes the top of the striking rod 33 as it passes over the surface of the striking rod 33, causing the striking rod 33 to rotate upward. When the push rod 31 moves away from the top of the striking rod 33, the coil spring 34 returns to its original state and drives the striking rod 33 to move in the original direction, causing the bottom end of the striking rod 33 to strike the top of the support rod 21, causing the support rod 21 and the cylinder 1 to vibrate as a whole, thereby improving the screening effect and efficiency of the screening device 2.
[0029] Specifically, such as Figure 2-3 As shown, a protrusion is provided on one side of the top of the striking rod 33. The two sides of the top of the protrusion are arc-shaped. By providing an arc-shaped protrusion on one side of the top of the striking rod 33, it is easier for the push rod 31 to enter the other side of the striking rod 33 when it moves back and forth and contacts the two sides of the top of the striking rod 33, so that the striking rod 33 can rotate without getting stuck. An auxiliary rod 35 is fixedly connected to one end of the striking rod 33. The auxiliary rod 35 is a rubber rod. By providing an auxiliary rod 35, the striking rod 33 will not make a loud noise when it strikes the top surface of the frame rod 21.
[0030] The working principle of this utility model is as follows:
[0031] S1. During the chemical purification of diamond micro powder, the servo motor 5 at the top of the operating rod 4 controls the lead screw 6 to rotate, causing one end of the support rod 21 to move up on the outer surface of the lead screw 6 and slide upwards along the inner wall of the operating rod 4. This causes the first and second permeable meshes 25 and 26 on the surface of the support rod 21 to rise. Diamond micro powder is then placed on the outer surface of the second permeable mesh 26. Purification acid is then added to the inside of the barrel 1. The servo motor 5 drives the lead screw 6 to rotate, controlling the support rod 21 to descend and cover the top of the barrel 1, allowing the diamond micro powder to contact the acid inside the barrel 1 for acid washing. Simultaneously, the drive motor 22 at the top of the support rod 21 drives the stirring rod 23 to rotate. The stirring rod 23 accelerates the reaction between the diamond and the acid. Impurities generated during the reaction remain on the surface of the second permeable mesh 26. Smaller particles of reactant material pass through the second permeable mesh 26 and enter the surface of the first permeable mesh 25, remaining on the surface of the first permeable mesh 25. When the drive motor 22 operates, it drives the spur gear 27 to rotate. The rotation of the spur gear 27 causes the outer surface of the gear to contact the half-gear. When the outer surfaces of 29 mesh, they drive the half gear 29 and cylinder 28 to rotate, causing the screw 211 to move upward on the inner wall of cylinder 28 and compress the spring 213 at the top of the round block 212. The screw 211 drives the pressure plate 210 to rise inside the barrel 1. After the flat gear 27 moves away from the surface of the half gear 29, the spring 213 returns to its original state and pushes the screw 211 downward inside the cylinder 28, causing the pressure plate 210 to move downward inside the barrel 1, generating downward pressure on the inside of the barrel 1, and causing the surface of the second mesh 26 to... The reactants can pass through the surface of the second permeable mesh 26 more quickly and enter the first permeable mesh 25. At the same time, when the flat gear 27 drives the half gear 29 and the cylinder 28 to rotate, one end of the push rod 31 passes through the surface of the striking rod 33 and pushes the top of the striking rod 33, causing the striking rod 33 to rotate upward. When the push rod 31 moves away from the top of the striking rod 33, the coil spring 34 returns to its original state and drives the striking rod 33 to move in the original direction, so that the bottom end of the striking rod 33 hits the top of the frame rod 21, causing the frame rod 21 and the barrel 1 to vibrate as a whole.
[0032] S2. After pickling is completed, stop the operation of drive motor 22, operate servo motor 5 to control the rise of frame rod 21, open the control valve at the top of discharge pipe 7 to discharge the liquid inside barrel 1, and remove the reactant material on the surface of first transparent mesh 25 and the impurities on the surface of second transparent mesh 26.
