Description

Technical Field

[0001] The invention relates to the technical field of diamond synthesis, and in particular to an early warning device for online detection of powder loss during liquid filling of an artificial diamond synthesis block. Background Art

[0002] In the process of synthetic diamond synthesis, the phenomenon of talc powder falling off during the liquid filling process and not being discovered in time causes local sealing failure and "explosion", which increases the consumption of the top hammer and production costs. Due to the limitation of the observation direction during operation, it is extremely difficult to find abnormalities in the rear-down direction, which is also the most common "explosion" direction. There is no effective online means for prevention in the industry, and operating specifications are generally used for constraints. There are huge objective variables: 1. By adjusting the amount of binder added and the ratio of coarse and fine talc, the probability of talc powder falling off is essentially reduced; 2. Control the calcination temperature of talc, improve the toughness of talc, and reduce the amount of powder falling off the sealing edge during the liquid filling process. 3. Adjust the filling pressure to control the forward speed of the top hammer, quickly form a sealing edge, and reduce the probability of talc powder falling off, but too fast can easily cause collisions and cause the entire synthetic block to be scrapped. In view of this, the inventor of the present application, after in-depth research, obtained an early warning device for online detection of powder falling off during liquid filling of artificial diamond synthetic blocks. Summary of the invention

[0003] The purpose of the present invention is to provide an early warning device for online detection of powder loss during liquid filling of a synthetic diamond synthesis block, which can realize real-time online detection of powder loss during the liquid filling process.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] In a preferred embodiment, a first inner cavity is provided in the first joint, a second inner cavity is provided in the second joint, one end of the liquid supply pipe and the annular heat exchange pipe is inserted into the first inner cavity, and the other end of the liquid return pipe and the annular heat exchange pipe is inserted into the second inner cavity.

[0008] In a preferred embodiment, an entry tube is provided on the side of one end of the liquid delivery tube away from the first joint, and an exit tube is provided on the side of the end away from the first joint. The lead wire is passed into the liquid delivery tube from the entry tube and passes out of the liquid delivery tube from the exit tube.

[0009] In a preferred embodiment, the lead wire has a functional segment, which is arranged in the outlet tube. The functional segment is provided with a tightening drive elastic ring piece. In a natural state, the tightening drive elastic ring piece bends toward a direction close to the connection point between the outlet tube and the liquid delivery tube.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0022] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0023] like Figures 1 to 5 As shown, an early warning device for online detection of powder loss during liquid filling of an artificial diamond synthesis block comprises a plurality of laser probes 7 distributed in an array, wherein the laser probe 7 comprises a probe body 12 and a lead 8, wherein the probe body 12 comprises a fixing plate 13, a transmitting module 14, a receiving module 15 and a processing module 16, wherein the transmitting module 14, the receiving module 15 and the processing module 16 are arranged on the fixing plate 13, and the lead 8 is connected to the processing module 16.

[0024] The present embodiment provides an early warning device for online detection of powder falling off during filling of an artificial diamond synthesis block, which is applied to a pyrophyllite 5 mold. The pyrophyllite 5 mold comprises an upper top hammer 1, a lower top hammer 2, a left top hammer 3, a right top hammer 4, a front top hammer and a rear top hammer. Pyrophyllite 5 is arranged between the upper top hammer 1, the lower top hammer 2, the left top hammer 3, the right top hammer 4, the front top hammer and the rear top hammer. The pyrophyllite 5 comprises a synthesis cavity 6. Diamond synthesis is achieved by pressurizing the upper top hammer 1, the lower top hammer 2, the left top hammer 3, the right top hammer 4, the front top hammer and the rear top hammer, and heating them simultaneously. The early warning device is arranged between the side parts of the top hammers, especially between the lower top hammer 2 and the adjacent top hammer. During installation, the fixing plate is attached to the top hammer, and the laser probe 7 detects whether the pyrophyllite 5 has fallen off through signal detection. Specifically, the detection signal starts working from the time of filling with liquid, and the fallen talc 5 slides to the position of the probe body 12, causing the cyclic comparison of the distance detection data to decrease sharply. After the difference is abnormal, the excitation working mode is stopped and an alarm is prompted; the detection signal judgment is cut off after the heating is stopped to avoid false alarms of powder falling when the top hammer returns and the block is taken, which affects the normal synthesis; the module of this device is integrated, which is convenient for maintenance and repair. Through array arrangement, full coverage of the monitoring range is achieved, thereby realizing real-time online safety warning.

[0025] In order to ensure that the laser probe 7 works in a reasonable temperature range, the laser probe 7 also includes a liquid cooling device, which includes a liquid supply pipe 17, a heat exchanger and a liquid return pipe 19. The heat exchanger includes a first joint 20, a second joint 21 and a plurality of annular heat exchange pipes 22. The annular heat exchange pipe 22 is arranged on the fixing plate 13 and surrounds the transmitting module 14 and the receiving module 15. The two ends of the annular heat exchange pipe 22 are respectively connected to the first joint 20 and the second joint 21. The first joint 20 is connected to the liquid supply pipe 17, and the second joint 21 is connected to the liquid return pipe 19. During the working process, the coolant is sent into the heat exchanger through the liquid supply pipe 17, and the coolant after heat exchange is refluxed through the liquid return pipe 19 for re-cooling. In the heat exchanger, the coolant passes through the annular heat exchange pipe 22 to reduce the temperature of the area where the annular heat exchange pipe 22 is located, so that the probe body 12 works in a reasonable temperature range.

[0026] In order to achieve connection between the various components, a first inner cavity is provided in the first joint 20, and a second inner cavity is provided in the second joint 21. One end of the liquid supply pipe 17 and the annular heat exchange pipe 22 are inserted into the first inner cavity, and the other end of the liquid return pipe 19 and the annular heat exchange pipe 22 are inserted into the second inner cavity.

[0027] In order to effectively protect the lead wire 8, an inlet pipe is provided at one end of the liquid delivery tube 17 away from the first joint 20, and an outlet pipe 18 is provided at one end of the liquid delivery tube 17 away from the first joint 20. The lead wire 8 is passed into the liquid delivery tube 17 from the inlet pipe, and passes out of the liquid delivery tube 17 from the outlet pipe 18. By arranging the lead wire 8 in the liquid delivery tube 17, the lead wire 8 is protected, and the complexity of the circuit is effectively reduced.

[0028] In order to realize the setting of the lead wire 8, the lead wire 8 has a functional section 9, which is arranged in the outlet tube 18. The functional section 9 is provided with a squeeze-driven elastic ring sheet. In a natural state, the squeeze-driven elastic ring sheet is bent in a direction close to the connection point between the outlet tube 18 and the liquid delivery tube 17. In the process of inserting the lead wire 8 into the liquid delivery tube 17, the upper liquid delivery tube 17 is continuously filled with liquid, and the liquid impacts the squeeze-driven elastic ring sheet 10, driving the lead wire 8 to move in the liquid delivery tube 17, so that the lead wire 8 can penetrate the liquid delivery tube 17; after the lead wire 8 penetrates, the lead wire 8 is pulled back, so that the squeeze-driven elastic ring sheet retreats. Due to its shape setting, during the retreat process, it rubs against the inside of the outlet tube 18, causing its deformation, and is squeezed in the outlet tube 18, so as to achieve the fastening of the lead wire 8 and provide a certain sealing effect.

[0029] In order to make it easier for the lead wire 8 to enter the outlet tube 18, the angle between the outlet tube 18 and the liquid delivery tube 17 is set to be between 170 and 180 degrees.

[0030] In order to further make it easier for the lead wire 8 to enter the outlet tube 18, a magnet sheet is provided on the inner wall of the outlet tube 18, and the magnet sheet is provided at the connection between the outlet tube 18 and the liquid delivery tube 17. An attraction sheet 11 is provided at the end of the lead wire 8, and the attraction sheet 11 is made of magnetic material. When the end of the lead wire 8 reaches the connection between the outlet tube 18 and the liquid delivery tube 17, the magnet sheet attracts the attraction sheet 11, so that the end of the lead wire 8 is close to the outlet tube 18, thereby allowing the lead wire 8 to smoothly enter the outlet tube 18.

[0031] In order to facilitate the arrangement of the lines, the liquid delivery pipe 17 and the liquid return pipe 19 are wrapped with a thermal insulation film 23, so that the liquid delivery pipe 17 and the liquid return pipe 19 form a branch 24, and the thermal insulation film 23 is also wrapped around multiple branches 24, so that multiple branches 24 together form a main circuit 25.
