[0003] Chinese utility model patent application CN219682458U discloses a synthetic diamond manufacturing equipment, comprising a batching device, a graphite column press, a drying chamber, and a six-sided top press. The batching device includes a first metering hopper, a second metering hopper, a mixing tank, a temporary storage tank, and a feeding auger.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-3 As shown, a graphite batching device for diamond synthesis includes a first mounting frame 1, a second mounting frame 2 fixedly mounted on the first mounting frame 1, a mixing chamber 3 fixedly mounted on the first mounting frame 1, and a graphite silo 4 and a catalyst silo 5 fixedly mounted on the second mounting frame 2. Specifically, a pair of brackets 6 are fixedly mounted on the second mounting frame 2, and the graphite silo 4 and the catalyst silo 5 are respectively mounted on the brackets 6. The outlets of the graphite silo 4 and the catalyst silo 5 are fixedly connected to a weighing scale 8, and a feeding valve is provided on the outlet of the graphite silo 4 and the catalyst silo 5. 7. Controlling material feeding: The weighing scale 8 is used for weighing. When the weighing value reaches the preset value, the feeding valve 7 closes. The weighing scale 8 is connected to the conical distribution plate 12. After the feeding valve 7 closes when the weighing value reaches the preset value, the discharge gate of the weighing scale 8 opens, and the material falls into the conical distribution plate 12. A cover 14 is provided above the conical distribution plate 12. One end of the conical distribution plate 12 is rotatably connected to the cover 14, and the other end is rotatably connected to the mixing chamber 3. A second support 9 is fixedly provided between the cover 14 and the mixing chamber 3. The weighing scale 8 is set on the cover 14. In one embodiment of this invention, a feeding frame 20 is fixedly installed at the lower end of the conical distributing disc 12. The feeding frame 20 has several equally spaced through slots 21. A stirring shaft 18 is fixedly installed on the feeding frame 20 and rotatably mounted within the mixing chamber 3. A driving assembly for rotating the conical distributing disc 12 is fixedly installed on the outer ring of the conical distributing disc 12. The driving assembly includes a driven wheel 15, which is fixedly installed on the outer ring of the conical distributing disc 12. A drive motor 13 is fixedly installed on the side of the second mounting bracket 2. The output shaft of the drive motor 13 is fixedly connected to the drive wheel 19. The drive wheel 19 meshes with the driven wheel 15. When the drive motor 13 is started, the drive wheel 19 is driven to rotate. The rotation of the drive wheel 19 drives the driven wheel 15 to rotate, thereby driving the conical distribution plate 12 to rotate at high speed. The falling material hits the inner wall of the conical distribution plate 12 and is effectively dispersed. It falls into the mixing chamber 3 through the evenly distributed through grooves 21 and is mixed twice by the stirring shaft 18. As one embodiment of this invention, a blower 10 is fixedly installed on the first mounting frame 1. An exhaust pipe 11 is fixedly installed at the exhaust port of the blower 10. The exhaust pipe 11 is connected to the mixing chamber 3. A valve (not shown in the figure) is installed on the exhaust pipe 11. When the valve is opened, the blower 10 is started to extract the gas in the mixing chamber 3, forming a negative pressure in the mixing chamber 3. This accelerates the discharge of the material in the conical distribution plate 12. At the same time, the downward airflow can drive the flying catalyst powder downward, promoting its mixing with the graphite particle powder with a larger specific gravity.

[0021] As one embodiment of this invention, a discharge port 16 is fixedly provided below the mixing chamber 3, and a discharge valve 17 is provided on the discharge port 16, through which the mixed raw materials are discharged.

[0022] Working principle: Open the feed valve 7 to control the feeding of graphite silos 4 and catalyst silos 5. When the weighing value of the weighing scale 8 reaches the preset value, the feed valve 7 closes. The discharge gate of the weighing scale 8 opens, and the material falls into the conical distribution plate 12. Start the drive motor 13 to drive the drive wheel 19 to rotate. The rotation of the drive wheel 19 drives the driven wheel 15 to rotate, thereby driving the conical distribution plate 12 to rotate at high speed. The falling material hits the inner wall of the conical distribution plate 12 and is effectively dispersed. It falls into the mixing chamber 3 through the evenly distributed channels 21. Start the exhaust fan 10 to extract the gas in the mixing chamber 3 and form a negative pressure in the mixing chamber 3 to accelerate the discharge of the material in the conical distribution plate 12. Secondary mixing is achieved through the stirring shaft 18. The mixed raw material is discharged through the discharge port 16.
