Abstract
Description
Technical Field
[0001] This utility model belongs to the field of diamond production technology, specifically relating to an air intake mechanism for diamond growth. Background Technology
[0002] Diamond possesses many excellent properties, such as high hardness, low coefficient of friction, high thermal conductivity, and good chemical stability, making it widely applicable in industries such as electronics, optics, and machinery. In current diamond production processes, the gas intake system is crucial. Existing systems allow hydrogen and methane to directly enter the reactor, resulting in unstable and uneven gas flow, which affects the efficiency of diamond vapor deposition. Furthermore, existing hydrogen, methane, and argon gas lines lack backup systems; when these lines fail, no backup lines are available, impacting diamond production. Utility Model Content
[0003] In response to the shortcomings and defects of existing technologies, the inventors, based on their extensive experience in the field of diamond production technology, developed an air intake mechanism for diamond growth.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an air intake mechanism for diamond growth, comprising a reactor, wherein the reactor has a built-in cooling structure, a substrate is disposed above the cooling structure, a first mixer and a second mixer are disposed on the upper left side of the reactor, a mixing channel is connected above the first mixer, a premixer is connected above the mixing channel, the premixer has a built-in first mixing component and a second mixing component, a methane pipe is connected above the first mixing component, a methane branch pipe is disposed on the methane pipe, a hydrogen pipe is connected above the second mixing component, a hydrogen branch pipe is disposed on the hydrogen pipe, and both the first mixing component and the second mixing component are gourd-shaped.
[0005] Furthermore, the first mixing component has a plurality of first spray holes, and the second mixing component has a plurality of second spray holes. Both the first and second mixing components are made of a plurality of hollow spheres connected vertically, and each hollow sphere has four spray holes.
[0006] Furthermore, the second mixer is wrapped around the outside of the first mixer, the first mixer has third spray holes on its left and right sides, and the second mixer has a fourth spray hole at its bottom.
[0007] Furthermore, the methane pipe is equipped with a methane self-control valve, the methane branch pipe is equipped with a methane branch valve, the hydrogen pipe is equipped with a hydrogen self-control valve, the hydrogen branch pipe is equipped with a hydrogen branch valve, the argon pipe is equipped with an argon self-control valve, and the argon branch pipe is equipped with an argon branch valve.
[0008] Furthermore, a cooling water inlet pipe is connected to the left side of the cooling structure, and a cooling water outlet pipe is connected to the right side of the cooling structure.
[0009] Furthermore, a vacuum tube is connected to the lower right side of the reactor, and a vacuum pump is connected to the vacuum tube.
[0010] Compared with existing technologies, this invention has the following advantages: By incorporating a premixer, a first mixer, a second mixer, a hydrogen branch pipe, and a methane branch pipe, this invention allows the hydrogen and methane gas streams to be dispersed and uniformly introduced into the reactor. While ensuring uniform gas flow, it also reduces the gas velocity, resulting in a stable and uniform gas flow, thus improving the stability and uniformity of the gas flow and guaranteeing the diamond deposition efficiency. When the hydrogen, methane, or argon gas pipes experience leaks or other unusable malfunctions, the gas source can be switched to the hydrogen, methane, or argon branch pipes, thereby ensuring normal diamond production.
