[0010] In one specific implementation, the pipe body is inclined relative to the horizontal plane; the feeding device is located above the pipe body;

[0011] The number of partitions is multiple, and the multiple partitions are arranged around the axis of the tube body, with the length direction of each partition parallel to the axis of the tube body.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0024] To facilitate understanding of the diamond decarburization device provided in this application embodiment, its application scenario is first described. The diamond decarburization device provided in this application embodiment is applied in the diamond production process. Currently produced diamonds will have residual carbon powder, thus requiring decarburization. However, current decarburization methods often use resistance wire heating or microwave heating to heat the diamond, resulting in relatively low heating efficiency. Therefore, this application embodiment provides a diamond decarburization device to improve the decarburization efficiency of diamonds, which will be described in detail below with reference to specific embodiments and accompanying drawings.

[0025] refer to Figure 1 and Figure 2 , Figure 1 The diagram shows a side view of the diamond decarburization device provided in an embodiment of this application. Figure 2 This diagram shows a top view of the diamond decarburization device provided in an embodiment of this application. The diamond decarburization device mainly includes a magnetic induction coil 30 and a conductive delivery pipe 10. The magnetic induction coil 30 generates a magnetic field after conducting electricity, while the conductive delivery pipe 10 is used to transport diamond. In a specific arrangement, the conductive delivery pipe 10 is located inside the magnetic induction coil 30, with the magnetic induction coil 30 spirally fitted around the conductive delivery pipe 10, and the magnetic induction coil 30 and the conductive delivery pipe 10 are electrically isolated. That is, when the magnetic induction coil 30 and the conductive delivery pipe 10 are specifically arranged, their axes are collinear or parallel.

[0026] Furthermore, during the arrangement, the conductive transport tube 10 can rotate relative to the magnetic induction coil 30. During the rotation of the conductive transport tube 10, due to its conductivity, it induces a current and heats itself when cutting the magnetic field lines. The diamond located within the conductive transport tube 10 is continuously heated during this transport process, and any residual carbon powder on the diamond can be oxidized with oxygen in the air to produce carbon dioxide. This achieves the effect of decarbonizing the diamond.

[0027] In addition, the diamond decarburization device also includes a feeding device 20, which is used to continuously feed diamonds into the conductive conveying pipe 10, thereby ensuring that the conductive conveying pipe 10 can continuously convey diamonds.

[0028] It should be understood that the magnetic field generated by the magnetic induction coil 30 when energized should be able to ensure that the conductive delivery tube 10 can heat the diamond being delivered to the point where the carbon powder can be oxidized by oxygen in the air.

[0029] The conductive conveying pipe 10 conveys diamonds in the direction of its axis. One end of the conductive conveying pipe 10 is an inlet that cooperates with the feeding device 20, and the other end is an outlet. Diamonds enter the conductive conveying pipe 10 from the inlet and are transported to the outlet through the conductive conveying pipe 10. During the transport process, carbon powder reacts with oxygen.

[0030] As can be seen from the above description, the diamond decarburization device provided in this application embodiment continuously feeds diamonds into the conductive conveying pipe 10 using a feeding device 20. A magnetic induction coil 30 located outside the conductive conveying pipe 10 generates a magnetic field after being energized. During rotation, the conductive conveying pipe 10 cuts the magnetic field lines and generates an induced current. This induced current heats the conductive conveying pipe 10, causing the carbon powder adhering to the diamonds to react with oxygen in the air. In this process, the diamonds are continuously conveyed through the conductive conveying pipe 10 and undergo an oxidation reaction during transport, improving the decarburization efficiency of the diamonds and thus increasing the diamond production efficiency. Simultaneously, using induction heating to heat the diamonds generates higher thermal efficiency, thereby improving energy utilization.

[0031] In addition, during the diamond transport process, the conductive transport tube 10 rotates around its axis while the transport direction is along the axis. Therefore, the diamond can roll inside the conductive transport tube 10 during the transport process, thereby increasing the contact area between the diamond and the air, and thus improving the oxidation reaction efficiency of the carbon powder.

[0032] It should be understood that the conductive conveying pipe 10 provided in the embodiments of this application is a metal pipe, such as a steel pipe, an aluminum pipe, or a metal pipe made of other conductive alloy materials.

[0033] Continue to refer to Figure 1 and Figure 2 As shown, the conductive delivery tube 10 provided in this embodiment includes a tube body 11 and a driving device 12 for driving the tube body 11 to rotate. In practical use, the tube body 11 is used to transport diamonds, and the rotation of the conductive delivery tube 10 refers to the rotation of the tube body 11. That is, the axis of the conductive delivery tube 10 is the axis of the tube body 11. Therefore, the axis around which the tube body 11 rotates is the axis of the tube body 11.

[0034] In one feasible configuration, the diamond decarburization device further includes a frame 70, with the tube 11 rotatably connected to the frame 70. A drive unit 12 is fixed to the frame 70 and drives the tube 11 to rotate. In this arrangement, the frame 70 supports the tube 11, and the rotational engagement between the tube 11 and the frame 70 allows the frame 70 to support the rotation of the tube 11. The drive unit 12 only drives the tube 11 to rotate. When the frame 70 and tube 11 are engaged, rollers are rotatably mounted on the frame 70; the tube 11 rolls with the rollers. These rollers support both ends of the tube 11 and axially limit its movement, ensuring that the tube 11 can rotate around its axis and preventing it from shifting during rotation. In addition, when fixing the magnetic induction coil 30, the magnetic induction coil 30 can be fixed to the frame 70 so that the frame 70 can support the magnetic induction coil 30, thereby ensuring that both the tube body 11 and the magnetic induction coil 30 can be stably supported.

[0035] For example, the driving device 12 may be a drive motor and a drive gear connected to the drive motor, and a toothed ring may be provided on the outer wall of the tube 11, so that the tube 11 can be rotated by the meshing of the drive gear and the toothed ring.

[0036] like Figure 3 As shown, in order to ensure the diamond conveying effect, a partition 13 is also provided inside the tube 11. The partition 13 isolates the diamond conveying channel in the tube 11 so that the diamond is conveyed from one end of the tube 11 to the other end along the channel.

[0037] Different methods can be used when specifically setting up the partition 13, and the same method can be used for the tube body 11.

[0038] In one feasible embodiment, the partition 13 can be a spiral partition 13, which is spirally arranged inside the tube body 11, thereby isolating a spiral channel for conveying diamonds within the tube body 11. When the tube body 11 rotates, the diamonds can roll within the spiral channel, thus achieving diamond transport. When using the partition 13 to form the spiral channel, the tube body 11 can be in a horizontal state or an inclined device relative to a horizontal plane. When the tube body 11 is inclined, the higher end of the tube body 11 can be the inlet, and the lower end can be the outlet. This facilitates the transport of diamonds under the influence of gravity.

[0039] In another feasible option, such as Figure 3 As shown, there are multiple baffles 13 arranged around the axis of the tube body 11, with the length direction of each baffle 13 parallel to the axis of the tube body 11. The channels formed on the baffles 13 are straight channels, and these straight channels are arranged around the axis of the tube body 11. In this configuration, the tube body 11 is inclined, meaning it is tilted relative to the horizontal plane, and the feeding device 20 is located above the tube body 11, allowing the diamond to be conveyed under gravity. Furthermore, in this configuration, the diamond can enter different channels as the tube body 11 rotates, thereby improving the rolling effect of the diamond, enhancing the contact between the diamond and oxygen, and improving the decarbonization efficiency.

[0040] Continue to refer to Figure 1 As shown, the diamond decarburization device provided in this embodiment further includes a heat insulation layer 40, which wraps around the tube body 11, while the magnetic induction coil 30 is wrapped around the outside of the heat insulation layer 40. That is, the conductive conveying tube 10, the heat insulation layer 40, and the magnetic induction coil 30 are nested together, with the conductive conveying tube 10 located in the innermost layer, the heat insulation layer 40 in the middle layer, and the magnetic induction coil 30 in the outermost layer. The heat insulation layer 40 is used to insulate the conductive conveying tube 10, reducing heat loss and allowing higher heat to concentrate within the tube body 11, thereby improving the decarburization efficiency of the diamond.

[0041] In the specific arrangement, the insulation layer 40 is directly wrapped around the conductive conveying pipe 10 and fixed relative to the conductive conveying pipe 10. When the pipe body 11 rotates, the insulation layer 40 rotates with the conductive conveying pipe 10. This insulation layer 40 can be made of common insulation materials such as asbestos and insulation cotton.

[0042] In addition, to improve the oxidation efficiency of the toner, the diamond decarbonization device provided in this application embodiment also includes an oxygen supply device. This oxygen supply device is used to supply oxygen into the conductive metal tube, that is, to the tube body 11. For example, the oxygen supply device includes an oxygen generating device and 80 gas supply pipes connected to the oxygen generating device. The 80 gas supply pipes are inserted into the tube body 11 and can deliver oxygen into the tube body 11 to increase the oxygen content in the tube body 11, thereby improving the decarbonization efficiency.

[0043] In one feasible embodiment, the oxygen supply direction of the oxygen supply device is opposite to the direction in which the conductive metal tube transports the diamond. For example... Figure 1 As shown, the oxygen supply pipe and the feeding device 20 are positioned on opposite sides of the pipe body 11, thereby improving the contact efficiency between oxygen and carbon powder. Especially at the discharge port, the contact area between carbon powder and oxygen can be increased, thus improving the carbon removal efficiency.

[0044] In one feasible embodiment, the diamond decarburization device further includes a receiving hopper 50 located at the outlet end of the conductive conveying pipe 10 and used to hold the diamonds output from the conveying pipe. The diamonds, after reaction within the pipe body 11, can fall directly into the receiving hopper 50 for storage.

[0045] In a feasible solution, to ensure control over the decarburization of the diamond and guarantee the decarburization effect, a thermocouple 60 is installed inside the conductive delivery pipe 10. This thermocouple 60 is used to detect the temperature inside the conductive delivery pipe 10. Operators can control the energization of the magnetic induction coil 30 based on the temperature data collected by the thermocouple 60. If the temperature is high, the power supply to the magnetic induction coil 30 can be reduced or disconnected. If the temperature is low, the power supply to the magnetic induction coil 30 can be increased. The magnetic induction coil 30 can be powered through a power supply cabinet 90. Similarly, the thermocouple 60 can also be powered through the power supply cabinet 90.

[0046] In an optional embodiment, the feeding device 20 provided in this application may include a feeding hopper 21 and a feeder 22 located between the feeding hopper 21 and the tube body 11. Diamonds can enter the feeder 22 through the feeding port, and the feeder 22 then conveys the diamonds into the conductive conveying tube 10.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments of this specification should be included within the scope of protection of this disclosure.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
