Abstract
Description
Technical Field
[0001] This utility model belongs to the field of synthetic diamond application equipment, and in particular relates to a variable frequency flow regulating liquid and automatic constant temperature device for the electrolytic purification of synthetic diamond. Background Technology
[0002] Synthetic diamonds are artificially synthesized diamonds. Their production processes are mainly divided into two categories: high-temperature high-pressure (HPHT) and chemical vapor deposition (CVD). Among them, the high-temperature high-pressure method simulates the high-temperature and high-pressure environment (temperature about 1300-1600℃, pressure about 5-6GPa) in which natural diamonds are formed, causing the carbon source (such as graphite) to undergo structural transformation and crystallize into diamond.
[0003] In existing technologies, after diamond production, electrolysis is required to dissolve and recover the metal catalysts (such as Fe, Ni, and Co) in the synthesized block into ions. Currently, the electrolysis process faces two technical challenges: firstly, the electrolyte is continuously consumed during electrolysis, leading to unstable metal ion deposition rates on the cathode plate surface; secondly, the electrolysis process is carried out at a specific heating temperature, and after a certain period of operation, the temperature inside the electrolytic cell deviates from the set temperature, thus affecting the electrolyte concentration. Based on the above analysis, upgrading the equipment to address the issues of water temperature fluctuations in the electrolytic cell and the stable and uniform deposition of metal ions during the electrolysis process is crucial. Utility Model Content
[0004] This invention addresses the technical problems existing in the current synthetic diamond electrolysis process by proposing a synthetic diamond electrolysis purification variable frequency flow rate and automatic temperature control device that is reasonably designed, simple in structure, easy to process, and can solve the problems of water temperature changes in the electrolytic cell and stable and uniform deposition of metal ions during the electrolysis process.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a variable frequency flow rate regulating and automatic temperature control device for the electrolytic purification of synthetic diamond, including an electrolytic cell. The electrolytic cell includes a first electrolytic cell, a second electrolytic cell, and a third electrolytic cell connected in sequence. The first and third electrolytic cells are also connected to an electrolyte conditioning tank. The first, second, and third electrolytic cells and the electrolyte conditioning tank form a circulating connection. The electrolyte conditioning tank is also connected to a replenishment tank. A replenishment pump is also provided between the electrolyte conditioning tank and the replenishment tank. The electrolyte conditioning tank also contains a heat exchange tube. The heat exchange tube is connected to a cooling water tank. A circulation pipe is provided between the cooling water tank and the heat exchange tube. The heat exchange tube and the cooling water tank are circulated through the circulation pipe. The cooling water tank is also connected to a cooling mechanism.

[0007] Preferably, the replenishment pump is equipped with a frequency converter, and both the electrolytic cell and the electrolyte conditioning tank are equipped with level gauges.
[0008] Preferably, the cooling water tank is also equipped with an electric heating element.
[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0010] This invention provides a variable frequency flow rate regulating and automatic temperature control device for the electrolytic purification of synthetic diamond. By setting up a cooling mechanism, it achieves cyclic cooling, ensuring that the electrolytic production process is maintained at the optimal temperature and ion concentration, thereby solving the technical problems existing in the existing electrolytic production process equipment.

Detailed Implementation
[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0016] Examples, such as Figure 1As shown, this embodiment aims to solve the problems of water temperature variation and stable and uniform deposition of metal ions in the existing diamond production electrolysis process. To achieve the above objective, this embodiment provides a variable frequency flow rate regulating liquid and automatic constant temperature device for synthetic diamond electrolysis purification, including an electrolysis cell. The electrolysis cell can be a common existing electrolysis cell, but in this embodiment, the electrolysis cell includes a first electrolysis cell 1, a second electrolysis cell 2, and a third electrolysis cell 3 connected in sequence. The main purpose of setting up two more electrolysis cells is to make the electrolyte migrate in one direction, thereby improving the electrolysis effect by facilitating heat exchange and metal ion concentration migration within the electrolysis cell.
[0017] To ensure stable and uniform deposition of metal ions, a stable liquid level is necessary. Therefore, an electrolyte conditioning tank 4 is connected to the first electrolytic cell 1 and the third electrolytic cell 3, forming a circulating connection between them. This allows for continuous replenishment of electrolyte through the conditioning tank 4, ensuring a stable liquid level within the electrolytic cells. To further stabilize the electrolyte level and temperature in the conditioning tank 4, a replenishment tank 5 is also connected to the conditioning tank 4. A replenishment pump 51 is installed between the conditioning tank 4 and the replenishment tank 5. In this embodiment, a frequency converter is installed on the replenishment pump 51, and level gauges are installed in both the electrolytic cells and the electrolyte conditioning tank 4. Thus, frequency conversion control maintains a constant liquid level within the electrolytic cells.
[0018] To ensure a constant electrolyte temperature, in this embodiment, a heat exchange tube 6 is also included in the electrolyte conditioning tank 4. The heat exchange tube 6 is connected to a cooling water tank 7, and a circulation pipe is provided between the cooling water tank 7 and the heat exchange tube 6, enabling cyclical communication between them. The cooling water tank 7 is also connected to a cooling mechanism 8. The cooling mechanism 8 is independently connected to the cooling water tank 7 for cyclical communication. This is because the temperature of the cooling water tank 7 is greatly affected by the natural environment. In low-temperature conditions, the cooling mechanism 8 can be omitted, and the cooling water tank 7 itself can achieve cooling.
[0019] The cooling mechanism 8 can be a structure that combines a cooling pipe with a compressor. In this embodiment, considering the cost of use, the cooling mechanism 8 is an air-cooled tower.
[0020] Considering the low temperatures in winter, an electric heating element 71 is installed in the cooling water tank 7 to ensure a constant electrolyte temperature and maintain stable heat exchange temperature.
[0021] The above settings maintain a constant liquid level in the electrolytic cell and facilitate circulating cooling, ensuring that the electrolytic production process is maintained at the optimal temperature and ion concentration, thus maintaining the best electrolysis efficiency.
[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
