Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cleaning cultured diamonds, and in particular to a device for cleaning cultured diamonds. Background Technology
[0002] Synthetic diamonds are typically grown under high temperature and pressure. Before synthesis, raw materials, catalysts, graphite, and other substances are mixed. After being grown under high temperature and pressure for a period of time, all the substances become a synthetic rod. Diamond crystals are distributed inside the synthetic rod. Removing excess substances yields the diamond crystals.
[0003] Impurities such as graphite, elemental metals, and oxides in the synthetic rod can adhere to the surface of the diamond crystal and are not easily removed directly. The existing removal method is to break the synthetic rod open and then put the blocky material containing the diamond crystal and other impurities into a container filled with an acidic or alkaline solution. The container is equipped with an ultrasonic generator and a stirring device. The cavitation effect of the ultrasonic waves and the stirring device are used to stir the solution. After the impurities react and dissolve completely with the solution, a clean diamond crystal is obtained. This kind of container is called a diamond cleaning device.
[0004] Existing diamond cleaning equipment often suffers from dead zones at the bottom and edges of the container during operation, leading to material sedimentation and poor cleaning effectiveness. Therefore, a new cleaning device for lab-grown diamonds is needed to address this issue. Utility Model Content

[0030] Example 1: See Figure 1-8 A diamond cleaning device includes a circular container 1, an ultrasonic generator 2, and a stirrer. The stirrer extends into the circular container 1, while the ultrasonic generator 2 is located outside the circular container 1. The stirrer includes a vertically arranged stirring shaft 31 and a stirring paddle 32. The stirring shaft 31 has a cavity with an air inlet at the top and a closed bottom. The stirring paddle 32 has several air holes 322 that communicate with the inner cavity of the stirring shaft 31. The device can blow air into the solution inside the circular container 1 during stirring, increasing the disturbance to the solution and materials within the container 1, thereby improving the cleaning effect.
[0031] The stirrer also includes a drive motor 34 and a bracket 33. The bracket 33 is L-shaped and includes a connected vertical plate and a horizontal plate.

The drive motor 34 is mounted on the horizontal plate, and the output end of the drive motor 34 is connected to the stirring shaft 31. The bracket 33 provides a platform for the installation of the drive motor 34, making the structure of the device more compact.
[0032] The stirring paddle 32 is horizontally positioned and includes a connecting pipe and several baffles. Both ends of the connecting pipe are sealed, and the interior of the connecting pipe communicates with the internal cavity of the stirring shaft 31. The baffles are all fixed to the bottom sidewall of the connecting pipe along its axis, and the baffles are evenly distributed along the axis of the connecting pipe. The air holes 322 are all located between adjacent baffles. The middle part of the connecting pipe is fixed to the stirring shaft 31. Two stirring paddles 32 are configured, one above the other, and are perpendicular to each other. Stirring paddle 32A is used to agitate the bottom of the circular container 1; stirring paddle 32B is used to agitate the upper part of the circular container 1. Furthermore, the airflow emitted by stirring paddles 32A and 32B is staggered to increase the agitation of the solution.

The drive motor 34 drives the stirring shaft 31 in sequence through gear B 382 and gear A 381, which leaves the top of the output shaft 341 open, leaving space for the installation of the rotary joint 35.
[0040] An anti-loosening nut 39 is installed on the output shaft 341. The anti-loosening nut 39 is installed below the gear B 382, and the bottom of the gear B 382 is in contact with the top of the anti-loosening nut 39.

[0049] ④ Stop the machine and discharge materials
[0050] The material is continuously cleaned, and once the cleaning requirement is met, the solution and diamond crystals in the circular container 1 are discharged and collected.
[0051] The working principle of this embodiment:
[0052] During the stirring process, air is blown into the solution in the circular container 1 to increase the disturbance of the solution and materials in the circular container 1, thereby improving the cleaning effect of the materials; the stirring paddle 32 is set to two paddles, one above the other, and the two stirring paddles 32 are set vertically to prevent the solution in the circular container 1 from swirling as a whole, thereby increasing the disturbance of the solution.

The difference is that both the drain pipe 12 and the injection pipe 11 are equipped with solenoid valves. This facilitates the control of the opening and closing of the drain pipe 12 and the injection pipe 11, reducing manual labor.
[0054] The device also includes a control box 4, which can control the solenoid valves on the drive motor 34, ultrasonic generator 2, drain pipe 12 and injection pipe 11 to improve the overall integrity of the device, reduce the difficulty of operation, and save manpower.
