Artificial diamond purification device

Abstract

This utility model relates to a synthetic diamond purification device. The device includes a stirring drum, an ultrasonic generator, and a stirrer. The stirrer extends into the stirring drum, while the ultrasonic generator is located outside the drum. A guide strip is provided on the lower part of the inner wall of the stirring drum, extending downwards along a spiral direction. In this synthetic diamond purification device, the guide strip on the lower part of the inner wall of the stirring drum can impede a portion of the solution during stirring, converting some of the solution's lateral movement into an impact towards the bottom of the stirring drum. This increases the disturbance to the bottom of the drum, preventing material from settling and improving the purification effect on diamond crystals.

Description

Technical Field

[0001] This utility model relates to the technical field of synthetic diamond cleaning equipment, and in particular to a synthetic diamond purification device. Background Technology

[0002] Synthetic diamonds are generally produced by using a six-sided press to cultivate powdered materials such as raw materials under high temperature and pressure. After cultivation, the raw materials will solidify into a columnar synthetic rod, and the diamond crystals will be encapsulated inside the synthetic rod. Therefore, to obtain diamonds, impurities other than diamonds need to be removed.

[0003] These impurities are generally graphite, metallic elements, and some related oxides, which can usually react with acidic or alkaline solutions and thus dissolve. Because diamond is chemically very stable, clean diamond can be obtained after the solution reaction process; this process is also known as diamond purification.

[0004] Diamond purification is generally carried out in a purification device. First, the synthetic rod is broken into small blocks, and then these blocks are put into a container containing an acidic or alkaline solution. The purification device is usually equipped with a stirring device and an ultrasonic generator. By using the cavitation effect of ultrasonic waves and stirring, the impurities on the blocks are gradually dissolved, leaving only clean diamond crystals.

[0005] Existing diamond purification equipment often suffers from dead zones in the container during operation, leading to material sedimentation and poor purification results. Therefore, a synthetic diamond purification device capable of solving this problem is needed. Utility Model Content

[0006] The purpose of this invention is to solve the above-mentioned problems and provide a device for purifying synthetic diamonds.

[0007] The technical solution of this utility model is: a synthetic diamond purification device, including a stirring drum, an ultrasonic generator, and a stirrer. The stirrer extends into the stirring drum, and the ultrasonic generator is located outside the stirring drum. A guide strip is provided on the lower part of the inner wall of the stirring drum, extending downward along a spiral direction. The guide strip on the lower part of the inner wall of the stirring drum can block a portion of the solution during stirring, converting some of the solution's lateral movement into an impact towards the bottom of the stirring drum, thereby increasing the disturbance to the bottom of the stirring drum and preventing the material from settling.

[0008] Preferably, a plurality of guide strips are provided, which are evenly arranged along the circumference of the side wall of the stirring drum, with gaps between adjacent guide strips. The gaps between adjacent guide strips allow a portion of the water flow to move along the direction of the guide strips, thereby increasing the disturbance to the internal solution of the stirring drum.

[0009] Preferably, the stirrer includes a vertically arranged stirring shaft and a stirring paddle, with the stirring paddle installed at the bottom of the stirring shaft; the stirring shaft is coaxial with the stirring drum.

[0010] Furthermore, the direction in which the guide strip extends matches the rotation direction of the stirring shaft. When the stirring shaft rotates, the stirring paddle agitates the solution, and the guide strip, which matches the rotation direction of the stirring shaft, can convert a portion of the solution from lateral movement to an impact towards the bottom of the stirring drum, thereby increasing the disturbance to the bottom of the stirring drum and preventing the material from settling to the bottom.

[0011] Furthermore, the stirrer also includes a drive motor and a support; the support is L-shaped and includes a vertical plate and a horizontal plate; the horizontal plate of the support is positioned above the stirring drum, and the vertical plate is fixed to the outer wall of the stirring drum;

[0012] The drive motor is mounted on the horizontal plate of the support frame and drives the stirring shaft. The support frame provides a platform for the installation of the drive motor, making the structure of the device more compact.

[0013] Furthermore, the drive motor is vertically mounted on top of the horizontal plate of the support, and its output shaft passes through the horizontal plate; the output shaft of the drive motor is coaxial with the stirring shaft. The drive motor is directly connected to the stirring shaft, resulting in a simple and reliable structure.

[0014] Furthermore, the drive motor is connected via a flexible coupling. This enhances the overall stability of the agitator and prevents damage to the drive motor from lateral impacts to the agitator shaft.

[0015] Preferably, the stirring drum is equipped with a drain pipe and a filling pipe; the drain pipe is located at the lower part of the outer side of the stirring drum, and the filling pipe is located at the upper part of the outer side of the stirring drum. This facilitates the drainage and replacement of the solution inside the stirring drum.

[0016] Furthermore, the drain pipe is positioned in the gap between adjacent guide strips. This prevents the drain pipe from interrupting the guide strips and affecting the disturbance effect on the bottom of the mixing drum during stirring.

[0017] Furthermore, both the drain pipe and the injection pipe are equipped with solenoid valves. This allows for easy control of the opening and closing of the drain pipe and the injection pipe, reducing manual labor.

[0018] The beneficial effects of this utility model are as follows: The synthetic diamond purification device of this utility model has the following advantages:

[0019] 1. The present invention provides a guide strip on the lower part of the inner wall of the mixing drum, which can block part of the solution when the agitator is stirring the solution, and change part of the solution from lateral movement to impact towards the bottom of the mixing drum, so as to increase the disturbance on the bottom of the mixing drum, prevent the material from settling to the bottom, and improve the purification effect of diamond crystallization.

[0020] 2. The drive motor of this utility model is connected by a flexible coupling, which can enhance the overall stability of the agitator and prevent damage to the drive motor caused by lateral impact of the agitator shaft. Attached Figure Description

[0030] Example 1: See Figure 1-8 A synthetic diamond purification device includes a stirring drum 1, an ultrasonic generator 4, and a stirrer. The stirrer extends into the stirring drum 1, and the ultrasonic generator 4 is located outside the stirring drum 1. A guide strip 13 is provided on the lower part of the inner wall of the stirring drum 1, extending downward in a spiral direction. The guide strip 13 on the lower part of the inner wall of the stirring drum 1 can block a portion of the solution during stirring, converting some of the solution's lateral movement into an impact towards the bottom of the stirring drum 1, thereby increasing the disturbance to the bottom of the stirring drum 1 and preventing the material from settling to the bottom.

[0031] Several guide bars 13 are provided, and the guide bars 13 are evenly arranged along the circumference of the side wall of the stirring drum 1, with gaps between adjacent guide bars 13. The gaps between adjacent guide bars 13 allow a portion of the water flow to move along the direction of the guide bars 13, thereby increasing the disturbance to the internal solution of the stirring drum.

[0032] The agitator includes a vertically arranged stirring shaft 22 and a stirring paddle 23, with the stirring paddle 23 mounted on the bottom of the stirring shaft 22; the stirring shaft 22 is coaxially arranged with the stirring drum 1.

[0033] The direction of the guide strip 13 extends in a direction that matches the rotation direction of the stirring shaft 22. When the stirring shaft 22 rotates, the stirring paddle 23 agitates the solution. The guide strip 13, which matches the rotation direction of the stirring shaft 22, can convert a portion of the solution from lateral movement to impact towards the bottom of the stirring tank 1, thereby increasing the disturbance to the bottom of the stirring tank 1 and preventing the material from settling to the bottom.

[0034] The stirrer also includes a drive motor 21 and a support 3; the support 3 is L-shaped and includes a vertical plate 32 and a horizontal plate 31; the horizontal plate 31 of the support 3 is positioned above the stirring cylinder 1, and the vertical plate 32 is fixed to the outer wall of the stirring cylinder 1.

[0035] The drive motor 21 is mounted on the horizontal plate 31 of the bracket 3, and the drive motor 21 drives the stirring shaft 22. The bracket 3 provides a platform for the installation of the drive motor 21, making the structure of the device more compact.

[0036] The drive motor 21 is vertically mounted on the top of the horizontal plate 31 of the bracket 3, and the output shaft of the drive motor 21 passes through the horizontal plate 31; the output shaft of the drive motor 21 is coaxial with the stirring shaft 22. The drive motor 21 is directly connected to the stirring shaft 22, and the structure is simple and reliable.

[0037] The drive motor 21 is connected via a flexible coupling 24. This enhances the overall stability of the agitator and prevents damage to the drive motor 21 from lateral impacts to the agitator shaft 22.

[0038] The stirring drum 1 is equipped with a drain pipe 12 and a filling pipe 11; the drain pipe 12 is located on the lower part of the outer side of the stirring drum 1, and the filling pipe 11 is located on the upper part of the outer side of the stirring drum 1. This facilitates the drainage and replacement of the solution inside the stirring drum 1.

[0039] The drain pipe 12 is positioned in the gap between adjacent guide bars 13. This prevents the drain pipe 12 from blocking the guide bars 13 and affecting the disturbance effect on the bottom of the mixing drum 1 during stirring.

[0040] The working process of this embodiment includes the following steps:

[0041] ①Injection

[0042] The prepared acidic or alkaline solution is injected into the stirring tank 1 through the injection pipe 11;

[0043] ②Start the ultrasonic generator 4, stirrer and air pump.

[0044] The solution is disturbed by the cavitation effect of the ultrasonic generator 4 and the stirrer.

[0045] ③ Feeding

[0046] Put the materials that need to be cleaned into the mixing drum 1;

[0047] ④ Stop the machine and discharge materials

[0048] The material is continuously stirred and purified. Once the purification requirements are met, the solution and diamond crystals in the stirring tank 1 are discharged and collected.

[0049] The working principle of this embodiment:

[0050] Several guide strips 13 are provided on the lower part of the inner wall of the mixing drum 1. When the agitator stirs the solution, the guide strips 13 block part of the solution and change the lateral movement of this part of the solution into an impact on the bottom of the mixing drum 1, so as to increase the disturbance on the bottom of the mixing drum 1, avoid the material from settling to the bottom, and improve the purification effect of diamond crystallization.

[0051] Example 2: See Figure 1-2 Example 2 is basically the same as Example 1, and the similarities will not be repeated. 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.

[0052] The device also includes a control box 5, which can control the solenoid valves on the drive motor 21, ultrasonic generator 4, drain pipe 12 and injection pipe 11 to improve the overall integrity of the device, reduce the difficulty of operation, and save manpower.
