Description

Technical Field

[0001] The present invention relates to the technical field of diamond synthesis, and in particular to a high-temperature and high-pressure diamond synthesis device. Background Art

[0002] Current domestic synthetic diamond synthesis technology typically utilizes a six-sided press. This press incorporates a synthetic core made of catalyst and diamond material within a pyrophyllite block. Conductive graphite sheets and conductive steel rings of equal diameter are placed at either end of the core. The six-sided press has six hydraulic cylinders capable of achieving a maximum pressure of 8 GPa, a maximum pressure of 25 GPa, and a maximum temperature of 2500°C. Heating can be achieved using optical wave conduction.

[0003] An existing six-sided top press slag removal device (Announcement No.: CN222267055U) has at least the following disadvantages: the above patent makes the cleaning brush contact and fit with the end face of the hydraulic push rod of the top press body, and then starts the second motor to drive the cleaning brush to remove the slag from the end face of the hydraulic push rod of the top press body; because the dust cleaned by the cleaning brush on the surface of the top hammer cannot be discharged in time, dust will still adhere to the surface of the top hammer after the cleaning brush is removed, resulting in incomplete cleaning of the surface of the top hammer. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a high-temperature and high-pressure diamond synthesis device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A diamond synthesis high temperature and high pressure device includes a six-sided top press, which is composed of six groups of hydraulic cylinders hinged to each other in six directions, and each group of hydraulic cylinders is equipped with a top hammer at its telescopic end, and further includes: A guide ring is detachably mounted on the end surface of the fixed end of the hydraulic cylinder, and the telescopic end of the hydraulic cylinder is arranged through the guide ring, and the end of the guide ring away from the hydraulic cylinder is an open structure; A swivel, the swivel being rotatably mounted on the inner wall of the open end of the guide ring and being capable of rotating inside the guide ring; The jet elbow is used to eject external gas to clean the end face of the top hammer. The jet elbow can be rotatably installed on the swivel and is used to retract the jet elbow when the top hammer is used.

[0006] As a further solution of the present invention, an air intake pipe connected to the interior of the guide ring is fixedly installed on the outer surface of the guide ring, and the air intake pipe and the guide ring are arranged tangently. A plurality of blades are fixedly installed at equal distances in the inner circumferential direction of the rotating ring near the guide ring, and the width of the blades is smaller than the width of the rotating ring.

[0007] As a further solution of the present invention, a connecting assembly is installed between the swivel and the jet elbow, and the connecting assembly includes a connecting block fixedly installed on the outside of the swivel, the connecting block is a hollow structure, and a through hole is opened between the bottom of the connecting block and the swivel, one end of the jet elbow is rotatably installed on the outer surface of the connecting block through a torsion bearing, the outer surface of the connecting block is opened with an air outlet connected to the jet elbow, and a cleaning assembly is installed at the pipe mouth of the jet elbow.

[0008] As a further solution of the present invention, a mounting bracket is fixedly installed inside the jet elbow near one end of the connecting block, a rotating shaft is fixedly installed on the outer surface of the mounting bracket, the rotating shaft passes through and is rotatably installed inside the connecting block, and a fan-shaped baffle is fixedly installed on the outer surface of the rotating shaft. When the jet elbow is in the retracted state, the fan-shaped baffle can block the interior of the connecting block, so that the air outlet and the through hole are not connected.

[0009] As a further solution of the present invention, the cleaning assembly includes a cover shell that is fixedly installed on the outer surface of the jet elbow, the cover shell is connected to the interior of the jet elbow, a rotating pipe is rotatably installed between the inner walls on opposite sides of the cover shell, a cleaning pipe is movably installed on the end of the rotating pipe that faces the same end as the jet elbow, a number of cleaning brushes are fixedly installed on the outer periphery of the cleaning pipe, and a conducting assembly is installed between the cleaning pipe and the rotating pipe.

[0010] As a further solution of the present invention, the conducting assembly includes an elastic rubber tube fixedly installed between the cleaning pipe and the rotating pipe. The elastic rubber tube is mutually conductive with the cleaning pipe and the rotating pipe. A plurality of through grooves are opened through the outer periphery of the rotating pipe.

[0011] As a further solution of the present invention, the end of the cleaning pipe away from the rotating pipe is a closed structure, and a blowing hole is opened through the outer periphery of the cleaning pipe near its closed end.

[0012] As a further solution of the present invention, a plurality of blades are evenly and fixedly installed on the outer circumference of the rotating pipe, and the blades extend into the interior of the jet elbow.

[0013] The beneficial effects of the present invention are: 1. When the gas flows inside the jet elbow, it will blow the blade to rotate, so that the blade can drive the elastic rubber tube and the cleaning tube to rotate through the rotating tube. At the same time, part of the gas will enter the elastic rubber tube and the cleaning tube through the through grooves on the rotating tube, so that the cleaning tube can be expanded outward by the gas and maintain a certain verticality, so that when the jet elbow rotates toward the top hammer, the cleaning brush on the outer periphery of the cleaning tube can stick to the surface of the hammer head. At the same time, the cleaning brush is driven to rotate by the cleaning tube to achieve the cleaning effect of the hammer head. In combination with continuous blowing on the surface of the hammer head, the dust cleaned by the cleaning brush can be blown away and discharged in time to prevent the dust from adhering to the hammer head again, resulting in incomplete cleaning of the top hammer surface. 2. As the gas inflates the cleaning tube, part of the gas will be blown out from the air holes opened on the outer periphery of the end of the cleaning tube. When the cleaning tube drives the air holes to rotate to a position relative to the hammer head, the blown gas will exert a certain reverse thrust on the cleaning tube, so that the cleaning tube can drive the cleaning brush away from the hammer head. After the air holes and the hammer head are staggered, the cleaning tube will drive the cleaning brush to bounce toward the hammer head under the elastic force of the elastic rubber tube, so that the cleaning brush can have a certain knocking effect on the hammer head, so as to better remove the dust adhering to the surface of the hammer head; 3. When the air is pumped into the guide ring through the air inlet pipe, the flowing air will drive the swivel to rotate through the blades, so that the swivel can drive the jet elbow and the cleaning component to rotate around the top hammer, so as to achieve a comprehensive cleaning effect on the hammer head.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] Refer to the attached Figure 1 -Attached Figure 8 A diamond synthesis high-temperature and high-pressure device includes a six-sided top press 1. During cleaning operations, a vacuum cleaner can be installed on the six-sided top press 1, and the suction end of the vacuum cleaner is directed toward the interior of the six-sided top press 1, so that the vacuum cleaner absorbs the dust cleaned from the six-sided top press 1. The six-sided top press 1 is composed of six groups of hydraulic cylinders 101 hinged to each other in six directions, and each group of hydraulic cylinders 101 is equipped with a top hammer 102 at its telescopic end. It also includes: The guide ring 2 is detachably mounted on the end face of the fixed end of the hydraulic cylinder 101. A mounting block is mounted on the outer periphery of the guide ring 2. The guide ring 2 can be mounted on the fixed end face of the hydraulic cylinder 101 through screws and the mounting block. The telescopic end of the hydraulic cylinder 101 passes through the guide ring 2, and the end of the guide ring 2 away from the hydraulic cylinder 101 is an open structure. The swivel 4 is rotatably mounted on the inner wall of the open end of the guide ring 2, and the swivel 4 can rotate inside the guide ring 2; The jet elbow 6 is used to eject external gas to clean the end surface of the top hammer 102. The jet elbow 6 can be rotatably installed on the swivel 4 and is used to retract the jet elbow 6 when the top hammer 102 is in use.

[0019] In this embodiment, an air intake pipe 3 connected to the interior of the guide ring 2 is fixedly installed on the outer surface of the guide ring 2. The air intake pipe 3 and the guide ring 2 are arranged tangentially so that the airflow entering the guide ring 2 can blow the swivel 4 to rotate through the blades 11. The swivel 4 is fixedly installed with a number of blades 11 at equal intervals in the circumferential direction of the inner side near the guide ring 2. The width of the blades 11 is smaller than the width of the swivel 4 so that the gas can circulate inside the swivel 4.

[0020] When air is pumped into the guide ring 2 through the air inlet pipe 3, the flowing airflow will drive the swivel 4 to rotate through the blades 11, so that the swivel 4 can drive the jet elbow 6 and the cleaning assembly to rotate around the top hammer 102, so as to achieve a comprehensive cleaning effect on the hammer head.

[0021] In this embodiment, a connecting assembly is installed between the swivel 4 and the jet elbow 6, and the connecting assembly includes a connecting block 5 fixedly installed on the outside of the swivel 4. The connecting block 5 is a hollow structure, and a through hole is opened between the bottom of the connecting block 5 and the swivel 4. One end of the jet elbow 6 is rotatably installed with the outer surface of the connecting block 5 through a torsion bearing 7. The outer surface of the connecting block 5 is penetrated by an air outlet 10 connected to the jet elbow 6. A cleaning assembly is installed at the pipe mouth of the jet elbow 6. A mounting bracket 19 is fixedly installed inside the jet elbow 6 near one end of the connecting block 5. A rotating shaft 8 is fixedly installed on the outer surface of the mounting bracket 19. The rotating shaft 8 is rotatably installed inside the connecting block 5, and a fan-shaped baffle 9 is fixedly installed on the outer surface of the rotating shaft 8. When the jet elbow 6 is in the retracted state, the fan-shaped baffle 9 can block the interior of the connecting block 5, so that the air outlet 10 is not conductive with the through hole.

[0022] After the six-sided top press 1 completes the high-temperature and high-pressure synthesis of diamonds and takes out the synthesized diamonds, the connection between the external air pump and the air inlet pipe 3 is connected, so that the external air pump pumps air into the interior of the guide ring 2 through the air inlet pipe 3, and the pumped gas enters the connecting block 5 through the through hole, so that the gas entering the connecting block 5 blows the fan-shaped baffle 9 upward, so that the fan-shaped baffle 9 drives the jet elbow 6 through the rotating shaft 8 and the mounting bracket 19 to overcome the torsion of the torsion bearing 7 and rotate in the direction of the top hammer 102, so that the pipe mouth of the jet elbow 6 can be aligned with the surface of the top hammer 102, so as to blow away the dust and other impurities on the surface of the top hammer 102, and avoid the accumulation of dirt on the hammer head causing uneven pressure distribution of the six-sided top press 1, thereby affecting the processing accuracy.

[0023] In this embodiment, the cleaning assembly includes a cover shell 12 that is fixedly installed on the outer surface of the jet elbow 6. The cover shell 12 is connected to the interior of the jet elbow 6. A rotating pipe 13 is rotatably installed between the inner walls on opposite sides of the cover shell 12. A cleaning pipe 15 is movably installed on the end of the rotating pipe 13 that faces the same direction as the nozzle of the jet elbow 6. A plurality of cleaning brushes 16 are fixedly installed on the outer periphery of the cleaning pipe 15. A conducting assembly is installed between the cleaning pipe 15 and the rotating pipe 13. The outer periphery of the rotating pipe 13 is uniform. The conducting assembly includes an elastic rubber tube 17 fixedly installed between the cleaning pipe 15 and the rotating pipe 13. The elastic rubber tube 17 is mutually conductive with the cleaning pipe 15 and the rotating pipe 13. A plurality of through grooves 20 are opened on the outer periphery of the rotating pipe 13 and a plurality of blades 14 are fixedly installed, and the blades 14 extend into the pipeline interior of the jet elbow 6.

[0024] When the gas flows inside the jet elbow 6, it will blow the blade 14 to rotate, so that the blade 14 can drive the elastic rubber tube 17 and the cleaning tube 15 to rotate through the rotating tube 13. At the same time, part of the gas will enter the elastic rubber tube 17 and the cleaning tube 15 through the through groove 20 opened on the rotating tube 13, so that the cleaning tube 15 can be expanded outward by the gas and maintain a certain verticality, so that when the jet elbow 6 rotates toward the top hammer 102, the cleaning brush 16 on the outer periphery of the cleaning tube 15 can stick to the surface of the hammer head, and at the same time, the cleaning brush 16 is driven by the cleaning tube 15 to rotate, thereby achieving a cleaning effect on the hammer head.

[0025] In this embodiment, the end of the cleaning pipe 15 away from the rotating pipe 13 is a closed structure, and a blowing hole 18 is formed through the outer periphery of the cleaning pipe 15 near the closed end.

[0026] While the gas inflates the cleaning tube 15, part of the gas will be blown out from the blowing holes 18 opened on the outer periphery of the end of the cleaning tube 15. When the cleaning tube 15 drives the blowing holes 18 to rotate to a position relative to the hammer head, the blown gas will exert a certain reverse thrust on the cleaning tube 15, so that the cleaning tube 15 can drive the cleaning brush 16 away from the hammer head. After the blowing holes 18 are staggered with the hammer head, the cleaning tube 15 will drive the cleaning brush 16 to bounce toward the hammer head under the elastic force of the elastic rubber tube 17, so that the cleaning brush 16 can have a certain knocking effect on the hammer head, so as to better remove dust adhering to the surface of the hammer head.

[0027] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: after the six-sided top press 1 completes the high-temperature and high-pressure synthesis of diamonds and takes out the synthesized diamonds, the connection between the external air pump and the air inlet pipe 3 is connected, so that the external air pump pumps air into the interior of the guide ring 2 through the air inlet pipe 3, and the pumped gas enters the connecting block 5 through the through hole, so that the gas entering the connecting block 5 blows the fan-shaped baffle 9 upward, so that the fan-shaped baffle 9 drives the jet elbow 6 through the rotating shaft 8 and the mounting frame 19 to overcome the torsion of the torsion bearing 7 and rotate in the direction of the top hammer 102, so that the pipe mouth of the jet elbow 6 can be aligned with the surface of the top hammer 102, so as to blow away impurities such as dust on the surface of the top hammer 102, thereby avoiding the accumulation of dirt on the hammer head causing uneven pressure distribution of the six-sided top press 1, thereby affecting the processing accuracy; When the gas inside the jet bent pipe 6 flows, it will blow the blade 14 to rotate, so that the blade 14 can drive the elastic rubber tube 17 and the cleaning pipe 15 to rotate through the rotating pipe 13. At the same time, part of the gas will enter the elastic rubber tube 17 and the cleaning pipe 15 through the through groove 20 provided on the rotating pipe 13, so that the cleaning pipe 15 can be expanded outward by the gas and maintain a certain verticality, so that when the jet bent pipe 6 rotates toward the top hammer 102, the cleaning brush 16 on the outer periphery of the cleaning pipe 15 can stick to the surface of the hammer head. At the same time, the cleaning brush 16 is driven by the cleaning pipe 15 to rotate, achieving the cleaning effect of the hammer head, and combined with continuous blowing on the surface of the hammer head, the dust cleaned by the cleaning brush 16 can be blown away and discharged in time, avoiding the dust from adhering to the hammer head again, resulting in incomplete cleaning of the surface of the top hammer 102. When the gas expands the cleaning tube 15, part of the gas will be blown out from the blowing holes 18 opened on the outer periphery of the end of the cleaning tube 15. When the cleaning tube 15 drives the blowing holes 18 to rotate to a position relative to the hammer head, the blown gas will exert a certain reverse thrust on the cleaning tube 15, so that the cleaning tube 15 can drive the cleaning brush 16 away from the hammer head. After the blowing holes 18 are staggered with the hammer head, the cleaning tube 15 will drive the cleaning brush 16 to bounce towards the hammer head under the elastic force of the elastic rubber tube 17, so that the cleaning brush 16 can have a certain knocking effect on the hammer head, so as to better remove dust adhering to the surface of the hammer head. When air is pumped into the guide ring 2 through the air inlet pipe 3, the flowing air will drive the swivel 4 to rotate through the blades 11, so that the swivel 4 can drive the jet elbow 6 and the cleaning component to rotate around the top hammer 102, so as to achieve a comprehensive cleaning effect on the hammer head; After the cleaning of the top hammer 102 is completed, the external air pump is turned off and the air supply is stopped, so that the jet elbow 6 can drive the cleaning component to rotate away from the top hammer 102 under the torsion action of the torsion bearing 7, avoiding the jet elbow 6 and the cleaning component from being too close to the top hammer 102, affecting the normal use of the top hammer 102.

[0028] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method 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 can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
