Embodiment 1

[0051] This embodiment provides a double-tube connection structure for detonation synthesis, including a drive tube 4 and a sample tube 2. Both the drive tube 4 and the sample tube 2 are circular tube structures, and the drive tube 4 is coaxially sleeved outside the sample tube 2. , the annular gap between the inner wall of the driving tube 4 and the outer wall of the sample tube 2 is used as a cavity 3; the top port and the bottom port of the sample tube 2 are provided with sealing end plugs 7, and the top port and the bottom port of the sample tube 2 are both located at the drive Inside tube 4. It also includes fixing parts, which are covered with fixing parts at the top port and the bottom port of the driving tube 4, which can prevent the main explosive from entering the cavity 3; The drive tube 4 moves toward the axis of the sample tube 2 from top to bottom, so that the drive tube 4 covers the top end plug 7 of the sample tube 2, the sample tube 2 and the bottom of the sam...

Embodiment 2

[0053] Further improvement on the basis of Example 1, the outer diameter of the portion of the end plug 7 that is in contact with the drive tube 4 is smaller than the outer diameter of the sample tube 2; further preferably, the end plug 7 is a frustum of a conical structure, and The large-diameter end of the frustum-conical structure is plugged into the port of the sample tube 2, and the small-diameter end of the frustum-conical structure is connected with the fixing piece.

Embodiment 3

[0055] Further improvement on the basis of Embodiment 1 or 2, when the detonation wave of the fixing part is transmitted to the connection between the end of the drive tube 4 and the fixing part after the detonation, the end of the driving tube 4 and the connection part of the fixing part are disconnected , the fixing part is scattered outward by the action of the stretching wave; As a preferred solution, the fixing member installed on the top of the drive tube 4 includes a fixing ring 9 and two layers of cover plates 10; one end of the fixing ring 9 is connected with the top of the drive tube 4, and the other end is connected with the cover plate 10; the cover plate 10 is used In the sealed cavity 3 , an annular groove is opened on the lower surface of the cover plate 10 , and the end of the fixing ring 9 can be inserted into the annular groove for fixing. The fixing member installed on the bottom of the driving tube 4 includes a fixing ring 9 and a base 11, one end of the fi...

Abstract

The invention discloses a double-tube connecting structure for detonation synthesis and a detonation synthesis device based on the double-tube connecting structure. The double-tube connecting structure comprises a driving tube, a sample tube and an end plug arranged at the port of the sample tube, wherein the driving tube sleeves the sample tube, and cavities exist between the driving tube and thesample tube and between the driving tube and the end plug. The structure further comprises fixing pieces, and the top end opening and the bottom end opening of the driving tube are covered with the fixing pieces. After detonation, detonation waves are sequentially transmitted from top to bottom and are impacted, and the driving tube performs centroid sliding motion towards the axis of the sampletube from top to bottom, so that the driving tube sequentially coats the top end plug of the sample tube, the sample tube and the bottom end plug of the sample tube from top to bottom. According to the device, a graphite sample can be effectively converted into high-purity diamond, the conversion rate can reach 90% or above, the converted product high-purity diamond can be completely recycled, therecycling rate reaches 100%, and industrial production can be achieved easily.

Description

technical field [0001] The invention relates to the technical field of new material synthesis, in particular to a double-pipe connection structure for detonation synthesis and a detonation synthesis device. Background technique [0002] Due to its excellent performance, diamond is widely used in high-end manufacturing industries such as precision tools, wear-resistant parts, coating of optical components, and processing of electronic product accessories. Diamond is not only an "industrial tooth", but also an "ultimate semiconductor". The third-generation wide-bandgap semiconductors and devices represented by diamond are the foundation of future integrated circuits and the development of the information age. , Functional devices and many other high-tech fields have huge application potential. [0003] Now diamond powder and products have been widely used in automobiles, machinery, tools, electronics, integrated circuits, mobile phones, aviation, aerospace, optical instrument...
