Description

Technical Field

[0001] This utility model relates to the field of graphite mixing, and in particular to a graphite mixing and feeding device for diamond synthesis. Background Technology

[0002] In diamond synthesis, graphite needs to be mixed with a specific catalyst (such as nickel-based, iron-based, or cobalt-based alloys) and undergo structural transformation through catalysis under high temperature and high pressure conditions. For purposes such as creating a uniform temperature and pressure field, powdered catalysts are generally selected for mixing with graphite.

[0003] Before feeding graphite and powdered catalyst, sampling and testing are generally required to confirm the uniformity of the mixing and ensure that the powder composition is consistent across batches. Current methods typically involve sampling at the outlet of the graphite feeding device, collecting a certain amount of mixed powder at different times. However, this method makes it difficult to guarantee the consistency of the mixed powder quality in each sample, requiring re-weighing and quantification during subsequent use, which is relatively cumbersome. Furthermore, the sampling process can easily introduce moisture, dust, and other impurities from the air, contaminating the mixed powder and affecting the sampling results.

[0004] In summary, the existing technology for diamond synthesis involves sampling the graphite mixed powder during feeding, which has problems such as inconsistent sampling quantity and easy contamination by impurities. Utility Model Content

[0005] This invention provides a graphite mixing and feeding device for diamond synthesis, which can solve the problems of inconsistent sampling and easy mixing of impurities when feeding graphite mixed powder for diamond synthesis in the prior art.

[0006] A graphite mixing and feeding device for diamond synthesis includes a feeding port located at the bottom of a mixing cylinder, and a sampling mechanism is provided inside the feeding port. The sampling mechanism includes: A feed pipe is slidably disposed inside the feed inlet, the feed pipe is inclined inside the feed inlet, a sampling tube is detachably connected inside the feed pipe, an inclined block is fixedly connected to the end of the feed pipe, a through groove is opened on the surface of the inclined block, a sealing block is slidably connected inside the feed inlet, the sealing block is perpendicular to the feed pipe, can be inserted into the feed pipe and completely fit against the inner wall of the feed pipe; a transmission assembly is disposed between the feed pipe and the sealing block; A sealing ring is fixedly installed on the surface of the feed port, and the sealing ring is slidably installed inside the feed pipe, with the distance between the edge of the sealing ring and the edge of the inner wall of the feed pipe being greater than zero; A distance limiting component is provided between the feed pipe and the discharge port to limit the sliding distance of the feed pipe.

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1 to 6As shown in the figure, an embodiment of the present invention provides a graphite mixing and feeding device for diamond synthesis, including a feeding port 1 located at the bottom of a mixing cylinder. It should be noted that the mixing cylinder is equipped with a stirring mechanism and a feeding mechanism, and the mixing of graphite and powdered catalyst can be achieved inside the mixing cylinder; A sampling mechanism is provided inside the feed inlet 1. The sampling mechanism includes: A feed pipe 21 is slidably disposed inside the feed port 1. The feed pipe 21 is inclined inside the feed port 1. A sampling pipe 22 is detachably connected inside the feed pipe 21. An inclined block 23 is fixedly connected to the end of the feed pipe 21. The inclined block 23 has a triangular cross-section, with its hypotenuse facing the sampling pipe 22. A through groove is formed on the surface of the inclined block 23, and the edge of the through groove is perpendicular to the hypotenuse of the inclined block 23. A sealing block 24 is slidably connected inside the feed port 1. The sealing block 24 is perpendicular to the feed pipe 21 and can be inserted into the feed pipe 21 and completely fit against the inner wall of the feed pipe 21. A transmission assembly is provided between the feed pipe 21 and the sealing block 24 to enable them to move towards each other. A sealing ring 25 is fixedly installed on the surface of the feed port 1. The sealing ring 25 is slidably installed inside the feed pipe 21, and the distance between the edge of the sealing ring 25 and the edge of the inner wall of the feed pipe 21 is greater than zero. A distance limiting component is provided between the feed pipe 21 and the discharge port 1 to limit the sliding distance of the feed pipe 21; In summary, the graphite mixing and feeding device for diamond synthesis provided by this utility model includes a feed pipe 21 slidably disposed inside the feed port 1, and a sampling tube 22 can be detached from the feed port. The specific capacity of the sampling tube 22 can limit the amount of mixture obtained by a single sampling. After the feed pipe 21 is inserted into the feed port 1, it can guide the mixture to flow into the sampling tube 22. When the feed pipe 21 slides to the outside of the feed port 1, the transmission component can drive the sealing block 24 to be inserted into the feed pipe 21 again, thereby preventing the mixture on the surface of the feed pipe 21 from continuously moving towards the sampling tube 22. At the same time, the remaining material between the sealing block 24 and the sampling tube 22 can fill the unfilled position at the inclined end of the sampling tube 22, ensuring that the sampling tube 22 collects a sufficient amount of mixture. In addition, a sealing ring 25 is fixedly disposed inside the feed port 1. The sealing ring 25 slides inside the feed pipe 21, which can ensure that the mixture between the outside of the feed port 1 and the sampling tube 22 is still in a sealed environment, preventing impurities from being mixed into the mixture. In some specific implementations, the transmission assembly includes an active column 31 fixedly mounted on the surface of the feed pipe 21 via a sliding component. The surface of the sealing block 24 is provided with a bending groove 32. The active column 31 is adapted to the bending groove 32. The edge of the bending groove 32 intersects the edge of the sealing block 24 to form a trapezoid, and the distance between the two sides of the trapezoid increases along the direction of material feeding. The edge of the bending groove 32 and the edge of the sealing block 24 form a trapezoid, that is, both ends of the bending groove 32 completely penetrate the sealing block 24. When the active column 31 slides to the end position, the sealing block 24 can slide and fall back to its original position under the action of gravity and insert into the feed pipe 21. In a further embodiment, a sliding groove 33 is provided on the surface of the feed pipe 21, and the sliding groove 33 is adapted to the active column 31; In a further embodiment, the sliding assembly includes a sliding rod 34 slidably disposed inside the sliding groove 33, and the surface of the feed pipe 21 is provided with a plurality of transverse grooves 35, the transverse grooves 35 being connected to the sliding groove 33 and being arranged perpendicularly to the sliding groove 33. In some specific implementations, the distance limiting component includes a distance limiting ring 41 slidably disposed on the surface of the feed pipe 21, two distance limiting posts 42 fixedly connected to the surface of the distance limiting ring 41, a distance limiting groove 43 formed on the surface of the feed pipe 21, the cross-section of the distance limiting groove 43 being comb-shaped, an arc-shaped groove 44 formed on the surface of the discharge port 1, the arc-shaped groove 44 being adapted to the distance limiting posts 42, a positioning groove 45 formed on each distance limiting post 42, and an arc-shaped rod 46 fixedly connected inside the arc-shaped groove 44, the arc-shaped rod 46 being adapted to the positioning groove 45; In a further embodiment, the sliding rod 34 is slidably disposed on the surface of the distance limiting ring 41; the distance that the feed pipe 21 can be inserted into the discharge port 1 can be changed by the distance limiting component, thereby enabling the collection of mixtures at different positions; In some specific implementations, an elastic ring 51 is fixedly connected inside the feed tube 21. The cross-section of the elastic ring 51 is C-shaped. The elastic ring 51 is adapted to the sampling tube 22. A limiting component for limiting the position is provided between the sampling tube 22 and the feed tube 21. In a further embodiment, the limiting component includes a fixing ring 52 rotatably disposed at the end of the feed tube 21, a push rod 53 slidably connected inside the fixing ring 52, a frosted block 55 fixedly disposed at the end of the push rod 53, and a curved groove 54 formed on the surface of the feed tube 21, the curved groove 54 being adapted to the push rod 53, and the distances between the two ends of the curved groove 54 and the middle of the feed tube 21 being unequal; In a further embodiment, an insertion ring is fixedly connected to the surface of the abrasive block 55, and the insertion ring is threadedly connected to the push rod 53; by rotating the abrasive block 55, the insertion ring is disengaged from the push rod 53, which allows the abrasive block 55 to be replaced. The detachable abrasive block 55 can be replaced according to actual needs during use to ensure the fixing effect of the abrasive block 55 on the sampling tube 22. The working principle of this utility model: When sampling is required, first insert the sampling tube 22 into the feed tube 21, so that the end of the sampling tube 22 contacts the elastic ring 51. Then rotate the fixing ring 52 to make the pushing rod 53 slide inside the curved groove 54, and the abrasive block 55 slides onto the surface of the sampling tube 22, fixing the sampling tube 22 by the abrasive block 55. Next, change the position of the limiting ring 41 and the sliding rod 34. First, slide the sliding rod 34 to make it disengage from the transverse groove 35. Then rotate the limiting ring 41 to make the arc-shaped rod 46 disengage from the positioning groove 45. Then slide the limiting ring 41 to the appropriate position, and then rotate the sliding rod 34 and insert the sliding rod 34 into the transverse groove 35. Simultaneously push the limiting ring 52. The distance ring 41 and the feed pipe 21 are connected so that the feed pipe 21 is quickly inserted into the discharge port 1. During the sliding process of the feed pipe 21, the active column 31 pushes the sealing block 24 out of the feed pipe 21 through the bending groove 32. Then, the distance ring 41 is made to fit with the discharge port 1. The distance ring 41 is rotated and the arc rod 46 is inserted into the positioning groove 45, waiting for the sampling tube 22 to take a sample. After the sampling is completed, the distance ring 41 is rotated and the distance ring 41 and the feed pipe 21 are pulled out. At this time, the sealing block 24 is inserted into the inside of the feed pipe 21 under the action of gravity. After the feed pipe 21 can no longer move, wait for the mixture to completely enter the sampling tube 22, and then rotate the fixing ring 52 to pull out the sampling tube 22.

Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
