Description

Technical Field

[0001] This utility model belongs to the field of artificial diamond manufacturing technology, and in particular relates to a diamond continuous growth device. Background Technology

[0002] Synthetic diamond is a type of diamond that is artificially synthesized. It has similar physical and chemical properties to natural diamond, but the production process is more controllable and the cost is relatively low. It is widely used in industrial, electronics, optical, and jewelry fields.

[0003] Most existing diamond growth equipment uses chemical vapor deposition, which deposits diamond films or particles through the chemical reaction of carbon-containing gases on a substrate under relatively low temperature and pressure conditions. This method can synthesize high-quality, large-size single-crystal or polycrystalline diamonds. However, in use, the seed crystal is usually fixed directly inside the equipment, which means that the equipment needs to be opened when the diamond is removed after processing, resulting in heat loss. Continuous diamond manufacturing requires a lot of energy.

[0004] To address these issues, we provide a continuous diamond growth apparatus. Utility Model Content

[0005] The purpose of this invention is to provide a continuous diamond growth device. By combining a heat dissipation prevention component and an automatic material unloading component, the invention solves the problem in existing continuous diamond growth devices where heat loss easily occurs when the produced diamond is removed, requiring reheating for each diamond production run and consuming a large amount of energy.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a diamond continuous growth device, including a tank, a heat dissipation prevention component and an automatic material unloading component. A heater is fixedly connected to the rear side of the inner cavity of the tank, and a pressurization pipe and an auxiliary gas delivery pipe are respectively connected to the top and bottom of the left side of the tank.

[0008] The heat dissipation prevention component is located on the top of the tank and includes a sealing plate. A placement shell is fixedly connected to the bottom of the sealing plate. The bottom of the placement shell extends into the inner cavity of the tank. A first motor is fixedly connected to the top of the sealing plate. The bottom of the output end of the first motor extends into the inner cavity of the placement shell and is fixedly connected to a rotating shell. A second motor is fixedly connected to the left side of the top of the tank. The bottom of the output end of the second motor extends into the tank and is fixedly connected to a screw. A threaded sleeve is threaded onto the surface of the screw. The right side of the threaded sleeve is fixedly connected to the placement shell.

[0009] The automatic unloading assembly is located on the rear side of the top of the tank and includes a mounting plate. An electric push rod is fixedly connected to the top of the mounting plate, and a push plate is fixedly connected to the front side of the output end of the electric push rod.

[0010] The present invention is further configured such that a limiting frame is fixedly connected to the front side of the top of the tank, and a transfer plate is slidably connected to the inner cavity of the limiting frame.

[0011] The present invention is further configured such that a pressure relief pipe is connected to the bottom of the right side of the tank, and a control valve is fitted on the surface of the pressure relief pipe, the pressurizing pipe and the auxiliary gas delivery pipe.

[0012] The present invention is further configured such that a sliding rod is fixedly connected to the right side between the top and bottom of the inner cavity of the tank, a sliding sleeve is slidably connected to the surface of the sliding rod, and the left side of the sliding sleeve is fixedly connected to the placement shell by a mounting bracket.

[0013] The present invention is further configured such that a sealing ring is fixedly connected to the bottom of the sealing plate, and the bottom of the screw is movably connected to the inner wall of the tank through a bearing.

[0014] The present invention is further configured such that sliding blocks are fixedly connected to both sides of the bottom of the rotating shell, and an annular groove for cooperating with the sliding blocks is provided at the bottom of the inner cavity of the placement shell.

[0015] The present invention is further configured such that a support column is fixedly connected to the bottom of the tank, and a stabilizing plate is fixedly connected to the bottom of the support column.

[0016] The present invention is further provided that an observation window is provided on the front side of the tank body, and a triangular reinforcing plate is fixedly connected to the bottom of the mounting plate.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, through the setting of a heat dissipation prevention component, activates the second motor after diamond production is completed. The second motor, in conjunction with the screw, controls the threaded sleeve and the placement shell to move upward. The placement shell moves out of the inner cavity of the tank. Then, the first motor is activated, driving the rotating shell to rotate, so that the notches of the rotating shell and the placement shell coincide, facilitating the removal of the diamond placed in the rotating shell. During the material removal process, the notch at the top of the tank is always blocked by the rotating shell and the placement shell, preventing heat from escaping from the tank. During continuous production, reheating is not required, reducing energy consumption.

[0019] 2. This utility model, through the setting of an automatic material unloading component, activates the electric push rod after the notches of the rotating shell and the placement shell overlap. The electric push rod drives the push plate to move, and the moving push plate pushes the diamond to the top of the transfer plate. Then the electric push rod is reset. At this time, the diamond is located at the top of the transfer plate, and the operator can pull out the transfer plate to transfer the diamond without waiting for the diamond to cool down and be taken out. At this time, the seed crystal can be put back into the rotating shell for continuous production.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
