[0002] Diamond, commonly known as diamond, is a mineral composed of carbon with a chemical formula of C. It is an allotrope of graphite and the original form of common diamond. The raw material of diamond is graphite. Graphite can be modified under high temperature and high pressure to form artificial diamond, so the raw material of diamond needs to be modified during diamond production.

[0003] For example, a device for modifying synthetic raw materials for artificial diamond disclosed in the patent with announcement number CN220345763U can modify the diamond raw materials, but it does not have the function of monitoring the state of graphite during the modification, resulting in an inability to accurately determine whether the graphite is modified into diamond, thereby reducing the effect of use.

The horizontal end of the second conductive rod passes through the corresponding end of the strip block. An arc-shaped copper bar is fixedly installed on the side away from the two strip blocks, and the two ends of the two arc-shaped copper bars are respectively connected to the horizontal ends of the two second conductive rods.

[0010] As a further technical solution of the present invention, a shift plate is rotatably installed on the top of the sealing disk, and a second telescopic rod is vertically rotatably installed on the top of the barrel cover.

[0014] A method for modifying raw materials for diamond synthesis comprises the following steps: S1: First, place the diamond raw material on the placement plate, and then use the electric telescopic rod to drive the first conductive rod to contact the diamond raw material. It should be noted that the diamond raw material is graphite with conductive properties. Then, install the barrel cover on the barrel body to seal the barrel body. Then, connect the electrical connection device to the power supply. At this time, the graphite block conducts current, so that the electromagnet works to generate suction to move the iron plate. The movement of the iron plate drives the shift plate to move. The movement of the shift plate drives the pressure relief pipe to move and block the pressure relief hole. In addition, the torsion spring also generates torque. S2: Pressurize the inside of the barrel body through the pressure pump. As the pressure inside the barrel body increases, the sealing disk will move upward and cause the spring rod to generate elastic force. The upward movement of the sealing disk drives the first copper block and the third copper block to move upward. At this time, the first copper block contacts the copper plate to make the heating block work, so as to heat and pressurize the inside of the barrel body. When the pressure inside the barrel body reaches the preset temperature and pressure, the first copper block is separated from the copper plate, and the pressure pump stops working at the same time, so as to modify the diamond raw material. During this period, if the temperature inside the barrel body decreases, the pressure inside the barrel body will also decrease. The elastic force generated by the spring rod will cause the sealing disk to move downward. The downward movement of the sealing disk drives the first copper block to move downward and contact the copper plate, so that the heating block works to heat and pressurize the gas inside the barrel body, and further the inside of the barrel body can be kept in a high temperature and high pressure state. S3: When the modification of the diamond raw material is completed and the graphite is modified into diamond, the diamond loses its conductive property, and the electromagnet stops working and no longer has suction on the iron plate. It should be noted that the suction generated by the electromagnet on the iron plate is greater than the torsion generated by the torsion spring. At this time, the torsion generated by the torsion spring will move the paddle plate, and the movement of the paddle plate drives the pressure relief pipe to move and connect with the pressure relief hole, and the stop column will limit the paddle plate. It should be noted that the torsion spring still has torsion after the paddle plate and the stop column contact, which ensures the stability of the connection between the pressure relief hole and the pressure relief pipe, and the rotation of the paddle plate drives the second telescopic rod to rotate The second telescopic rod rotates, the fixed plate rotates, the fixed plate rotates, the movable rod moves, and the movable rod moves, so that the first copper block and the opposite surface of the copper plate are not located in the same vertical plane, avoiding the heating block from working during pressure relief. The high-temperature and high-pressure gas inside the barrel is discharged from the pressure relief pipe. As the pressure inside the barrel becomes smaller and smaller, the elastic force generated by the spring rod will move the sealing disk downward. When the sealing disk drives the third copper block to contact the second copper block, the alarm will work to remind the staff that the modification of diamond pigment is completed.

[0015] The beneficial effects of the present invention are: Firstly, the present invention can automatically monitor the modification process of diamond raw material (graphite) by detecting the settings of the pressure relief component, the barrel body and the barrel cover. When the modification of the diamond raw material is completed and diamond is formed, the barrel body is automatically depressurized, and an alarm is automatically sounded after the pressure relief to remind the staff, thereby avoiding the situation where the modification state of the diamond raw material is unclear, thereby improving the use effect of the equipment; Secondly, the present invention, through the arrangement of the automatic heating and pressurizing component, the barrel body and the barrel cover, can automatically monitor the pressure inside the barrel body when modifying the diamond raw material. As soon as the pressure inside the barrel body decreases, the heating block automatically works to heat the air inside the barrel body to increase the gas pressure inside the barrel body, thereby ensuring the original modification effect of the diamond, and also avoiding the temperature drop when modifying the diamond raw material, thereby improving the use effect of the equipment.

The horizontal surface of the L-shaped frame 17 is rotatably sleeved on the telescopic end surface of the second telescopic rod 14. The telescopic end surface of the second telescopic rod 14 is sleeved with a torsion spring 18. The two ends of the torsion spring 18 are respectively mounted on the bottom of the horizontal side of the L-shaped frame 17 and the top of the dial plate 19.

As the pressure inside the barrel body 1 becomes smaller and smaller, the elastic force generated by the spring rod 10 will cause the sealing disk 9 to move downward. When the sealing disk 9 drives the third copper block 24 and the second copper block 23 to contact, the alarm 6 will work to remind the staff that the diamond pigment modification is completed.

[0023] The working principle of the present invention is as follows: firstly, the diamond raw material is placed on the placing plate 25, and then the electric telescopic rod 28 drives the first conductive rod 29 to contact the diamond raw material. It should be noted that the diamond raw material is graphite with conductive properties. Then, the barrel cover 2 is installed on the barrel body 1 to seal the barrel body 1. Then, the electrical connection device is connected to the power supply. At this time, the graphite block conducts current, so that the electromagnet 22 works to generate suction to move the iron plate 21. The movement of the iron plate 21 drives the shift plate 19 to move. The movement of the shift plate 19 drives the pressure relief pipe 8 to move and block the pressure relief hole 27. In addition, the torsion spring 18 also generates torque. The pressure pump 3 is used to pressurize the interior of the barrel body 1. As the pressure inside the barrel body 1 increases, the sealing disk 9 will move upward and cause the spring rod 10 to generate elastic force. The sealing disk 9 moves upward and drives the first copper block 11 and the third copper block 24 to move upward. At this time, the first copper block 11 contacts the copper plate 12 to make the heating block 26 work, so as to heat and pressurize the interior of the barrel body 1. When the pressure inside the barrel body 1 reaches the preset temperature and pressure, the first copper block 11 is separated from the copper plate 12, and the pressure pump 3 stops working at the same time, so as to modify the diamond raw material. During this period, if the temperature inside the barrel body 1 decreases, the pressure inside the barrel body 1 will also decrease. The elastic force generated by the spring rod 10 will cause the sealing disk 9 to move downward. The sealing disk 9 moves downward and drives the first copper block 11 to move downward and contact the copper plate 12, so that the heating block 26 works to heat and pressurize the gas inside the barrel body 1, and further the inside of the barrel body 1 can be kept in a state of high temperature and high pressure. When the modification of the diamond raw material is completed and the graphite is modified into diamond, the diamond loses its conductive property, and the electromagnet 22 stops working and no longer has suction on the iron plate 21. It should be noted that the suction generated by the electromagnet 22 on the iron plate 21 is greater than the torsion generated by the torsion spring 18. At this time, the torsion generated by the torsion spring 18 will cause the paddle plate 19 to move, and the movement of the paddle plate 19 drives the pressure relief pipe 8 to move and connect with the pressure relief hole 27, and the blocking column 20 will limit the paddle plate 19. It should be noted that after the paddle plate 19 and the blocking column 20 contact, the torsion spring 18 still has torsion, which ensures the stability of the connection between the pressure relief hole 27 and the pressure relief pipe 8. The rotation of the paddle plate 19 drives the second telescopic rod 14 to rotate, and the rotation of the second telescopic rod 14 drives The fixed plate 15 rotates, and the rotation of the fixed plate 15 drives the movable rod 16 to move. The movement of the movable rod 16 drives the copper plate 12 to move, so that the opposite surfaces of the first copper block 11 and the copper plate 12 are no longer located in the same vertical plane, and the heating block 26 is prevented from working during pressure relief. Then, the high-temperature and high-pressure gas inside the barrel body 1 is discharged from the pressure relief pipe 8. As the pressure inside the barrel body 1 becomes smaller and smaller, the elastic force generated by the spring rod 10 will cause the sealing disk 9 to move downward. When the sealing disk 9 drives the third copper block 24 to contact the second copper block 23, the alarm 6 works at this time, prompting the staff that the modification of the diamond pigment is completed, making the modification of the diamond raw material convenient and quick, thereby improving the use effect of the equipment.

[0024] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

The downward movement of the sealing disk (9) drives the first copper block (11) to move downward and contact the copper plate (12), so that the heating block (26) works to heat and pressurize the gas inside the barrel (1), and further the inside of the barrel (1) can be kept in a high temperature and high pressure state; S3: When the modification of the diamond raw material is completed and the graphite is modified into diamond, the diamond loses its conductive property, and the electromagnet (22) stops working and no longer has suction force on the iron plate (21). It should be noted that the suction force generated by the electromagnet (22) on the iron plate (21) is greater than the torsion force generated by the torsion spring (18). At this time, the torsion force generated by the torsion spring (18) will cause the paddle (19) to move, and the movement of the paddle (19) drives the pressure relief pipe (8) to move and connect with the pressure relief hole (27), and the stop column (20) will limit the paddle (19). It should be noted that after the paddle (19) and the stop column (20) are in contact, the torsion spring (18) still has torsion force, which ensures the stability of the connection between the pressure relief hole (27) and the pressure relief pipe (8). The rotation of the paddle (19) drives the second The telescopic rod (14) rotates, the second telescopic rod (14) rotates to drive the fixed plate to rotate, the fixed plate rotates to drive the movable rod (16) to move, and the movable rod (16) moves to drive the copper plate (12) to move, so that the opposite surfaces of the first copper block (11) and the copper plate (12) are not located in the same vertical plane, avoiding the heating block (26) from working during pressure relief. The high-temperature and high-pressure gas inside the barrel (1) is discharged from the pressure relief pipe (8). As the pressure inside the barrel (1) decreases, the elastic force generated by the spring rod (10) causes the sealing disk (9) to move downward. When the sealing disk (9) drives the third copper block (24) to contact the second copper block (23), the alarm (6) works to remind the staff that the modification of the diamond pigment is completed.
