[0002] Nickel plating with diamond micropowder is an important surface treatment process that can significantly improve the wear resistance, oxidation resistance, and adhesion to the metal substrate of diamond micropowder. It is widely used in the field of superhard material tool manufacturing. In the nickel plating process with diamond micropowder, the reaction process has high requirements for conditions such as temperature and stirring effect.
[0003] Existing diamond micron nickel plating reactors can only be heated or cooled by a single method, which is not convenient for switching according to the temperature requirements of different stages of the nickel plating reaction. This can easily lead to excessive temperature fluctuations. In terms of stirring, unidirectional stirring can easily cause the micron powder to settle and agglomerate, resulting in incomplete coating. Utility Model Content

[0022] like Figure 1-4 As shown, the present invention proposes a diamond micron nickel plating reactor, comprising a reactor 1 and an oil storage tank 2. The reactor 1 is a jacketed structure, and the top of the reactor 1 is detachably equipped with a lid 3. The lid 3 is equipped with a stirring element 4. A temperature regulating element 5 is provided between the oil storage tank 2 and the jacket of the reactor 1. An expansion buffer tank 23 is connected to the top of the oil storage tank 2, which can effectively cope with the volume expansion caused by changes in oil temperature, ensure the safe and stable operation of the entire temperature regulation system, and reduce safety hazards caused by abnormal pressure. The oil storage tank 2 contains heat transfer oil. The temperature regulating element 5 regulates the temperature of the reactor 1, and the stirring element 4 mixes the materials in the reactor 1.
[0023] like Figure 1-2As shown, the temperature regulating component 5 includes a circulating pump 6, an electric three-way valve 7, a tubular electric heater 8, and a plate heat exchanger 9. The circulating pump 6 is an immersion circulating pump and is installed at the bottom of the oil storage tank 2. Its output end passes through the oil storage tank 2 and is connected to the inlet of the electric three-way valve 7. The two outlets of the electric three-way valve 7 are independently connected to the inlet of the tubular electric heater 8 and the inlet of the plate heat exchanger 9, respectively. The outlets of the tubular electric heater 8 and the plate heat exchanger 9 are connected to the jacket. The electric three-way valve 7 switches the connection between the tubular electric heater 8 or the plate heat exchanger 9 and the jacket of the reactor 1, forming two independent temperature control paths. The top of the reactor 1 is provided with an oil outlet 10, which is connected to the oil storage tank 2. The electric three-way valve 7 closes the branch of the plate heat exchanger 9. The heat transfer oil is heated by the tubular electric heater 8 and enters the jacket. The electric three-way valve 7 switches to the branch of the plate heat exchanger 9, and the cooling water and hot oil exchange heat in the plate heat exchanger.
[0024] like Figure 2 and 4 As shown, a temperature sensor 11 is installed inside the reactor 1, and a PLC controller 12 is installed on the side wall of the reactor 1. The PLC controller 12 is electrically connected to the temperature sensor 11 and the electric three-way valve 7. The temperature sensor 11 monitors the temperature inside the reactor and the jacket in real time and transmits the data to the PLC controller 12. The PLC executes a PID algorithm and automatically adjusts the temperature according to the set temperature. Heating mode: the cooling branch of the electric three-way valve 7 is closed, and the electric heater is started to raise the temperature. Cooling mode: the electric three-way valve 7 is switched to the plate heat exchanger 9 branch, and cooling water is circulated to lower the temperature.
[0025] like Figure 2 As shown, the stirring component 4 includes a paddle 13 and a rotating frame 14. The top end of the paddle 13 rotates through the lid 3 and extends outward. A connecting sleeve 15 is rotatably fitted onto the top of the paddle 13. The connecting sleeve 15 rotates out from the top of the lid 3. The top of the rotating frame 14 is fixedly fitted onto the connecting sleeve 15. The bottom of the rotating frame 14 is rotatably fitted onto the bottom of the paddle 13. The outer side of the paddle 13 and the inner sidewall of the rotating frame 14 are provided with staggered paddle blades 16. The lid 3 is provided with a driving component 17 that drives the paddle 13 and the rotating frame 14 to rotate.
[0026] like Figure 3 As shown, the driving component 17 includes a driven bevel gear 18 fixedly sleeved on the top of the connecting sleeve 15 and a driven bevel gear 19 fixedly sleeved on the top of the paddle rod 13. The top of the vessel cover 3 is located on a fixed plate 20. A driving bevel gear 21 is rotatably mounted on the fixed plate 20, meshing with the driven bevel gear 18 and the driven bevel gear 19. A drive motor 22 is also mounted on the fixed plate 20. The output end of the drive motor 22 rotatably passes through the fixed plate 20 and is connected to the driving bevel gear 21.
[0027] In practical use, when heating is required, the PLC controller receives the temperature signal from the temperature sensor 11, determines that the current temperature is lower than the set value, automatically controls the electric three-way valve 7 to close the branch of the plate heat exchanger 9, starts the tubular electric heater 8, and the circulating pump 6 draws out the heat transfer oil from the bottom of the oil storage tank 2 and delivers it to the tubular electric heater 8 through the electric three-way valve 7. After the heat transfer oil is heated in the tubular electric heater 8, it enters the jacket of the reactor 1 to heat the reactor 1, so that the reaction temperature gradually rises to the set value.
[0028] While the temperature is rising, the drive motor 22 is started. The drive motor 22 drives the active bevel gear 21 to rotate. The active bevel gear 21 meshes with the driven bevel gear 18 and the driven bevel gear 19, which in turn drives the connecting sleeve 15 and the paddle rod 13 to rotate in opposite directions, i.e., stirring in two directions. This causes the paddle blades 16 on the rotating frame 14 and the paddle rod 13 to rotate and stir the material in the reaction vessel 1, promoting uniform mixing of the material.
[0029] If cooling is required during the reaction, the PLC controller controls the electric three-way valve 7 to switch to the plate heat exchanger 9 branch based on the feedback from the temperature sensor 11. At this time, the high-temperature heat transfer oil flows out from the jacket of the reactor 1 and enters the plate heat exchanger 9 to exchange heat with the cooling water. The cooled heat transfer oil then returns to the oil storage tank 2. At the same time, the circulation pump 6 continues to work to maintain the circulation of the heat transfer oil, so that the temperature inside the reactor 1 is reduced to a suitable range.
[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
