Description

TECHNICAL FIELD

[0001] The utility model relates to diamond micro powder production technical field especially point a kind of cladding instrument for diamond micro powder production. BACKGROUND

Through suitable coating treatment of diamond micro powder, its surface properties can be significantly improved.

[0003] Currently, for ceramic and polymer coating materials, solution method is usually used for coating processing. The specific process is to dissolve ceramic or polymer raw materials in a solvent according to a certain ratio, then form a uniform solution by stirring, heating and other methods, slowly add alumina powder into water, add dispersant at the same time, form stable alumina sol after stirring for several hours, then add diamond powder, add pressurized gas to the container, continuously stir under the condition of carrier gas, and finally complete the coating processing. However, in this process, during the process of adding diamond powder into the coating container, the coating equipment is difficult to continuously disperse the diamond powder in time, which leads to the easy caking of part of the diamond powder, and the slow diffusion speed of the diamond powder into the coating container. After a large amount of diamond powder is added into the coating container, the diamond powder in the coating container is more difficult to disperse quickly, which further affects the coating efficiency. SUMMARY

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1-5 The coating apparatus for diamond micron powder production shown includes a reaction vessel 1, a discharge pipe 17 at the bottom of the reaction vessel 1, a solenoid valve 18 on the discharge pipe 17, a controller 3 on one side of the reaction vessel 1, a top cover 6 at the top of the reaction vessel 1, a dispersion assembly at the bottom of the top cover 6, the dispersion assembly including a material box 12, a feed inlet 121 at the top of the material box 12, a sieving hopper 13 below the material box 12, a collection trough 131 at the top of the sieving hopper 13, a sieving plate 14 below the sieving hopper 13, and several holes at the bottom of the material box 12, the sieving hopper 13, and the sieving plate 14. A stirring rod 16 is installed inside the reaction vessel 1, the extended end of the stirring rod 16 extends upward and passes through the dispersion assembly, and the sieving hopper 13 and the sieving plate 14 can rotate with the stirring rod 16.

[0023] The top of the top cover 6 is provided with a feed pipe 7, the bottom end of the feed pipe 7 is connected to the feed port 121, the top of the feed pipe 7 is provided with a feed funnel 8, the top of the top cover 6 is provided with a liquid inlet pipe 71 on the side away from the feed pipe 7, and the top of the liquid inlet pipe 71 is provided with a liquid inlet funnel 81.

[0024] A protective plate 15 is provided below the sieve plate 14. The bottom of the protective plate 15 has several holes. It should be noted that both the coating liquid and the diamond powder can pass through the holes at the bottom of the protective plate 15. The protective plate 15 has the function of blocking the coating liquid below, preventing the coating liquid from splashing to the bottom of the sieve plate 14 due to stirring and blocking the holes at the bottom of the sieve plate 14. This helps to maintain the continuous feeding of diamond powder.

[0025] In this embodiment, the prepared coating solution is poured into the inlet funnel 81. The coating solution contains coating material. After passing through the inlet pipe 71, the coating solution passes through the hole at the top of the material box 12 (e.g., Figure 4 As shown), it then flows downward through the screening hopper 13 and the screening plate 14;

[0026] Diamond micro powder is poured into the feed funnel 8, and then enters the material box 12 through the feed pipe 7 and the feed port 121. The material box 12 has a hollow structure and can store some diamond micro powder. As diamond micro powder is continuously added, it falls down through the bottom holes into the collection tank 131 of the sieving hopper 13. At the same time, the stirring rod 16 is rotating rapidly, which drives the sieving hopper 13 and the sieving plate 14 to rotate synchronously. During the rotation of the sieving hopper 13 and the sieving plate 14, the diamond micro powder falls evenly down through the bottom holes of the sieving hopper 13 and the sieving plate 14 into the reaction vessel 1, so as to achieve the purpose of dispersing the diamond micro powder. The diamond micro powder is fully mixed with the coating liquid, and under high temperature, the coating material adheres to the surface of the diamond micro powder, thereby achieving the purpose of coating processing.

[0027] like Figure 1 and Figure 2 As shown, a drive motor 11 is provided on the top of the top cover 6, and the output shaft of the drive motor 11 is connected to the stirring rod 16. When the controller 3 is started, the drive motor 11 is started. The output shaft of the drive motor 11 drives the stirring rod 16 to rotate. The stirring rod 16 rotates in the reaction vessel 1 and stirs the coating liquid, so that the coating liquid and diamond micro powder are fully mixed.

[0028] like Figure 1 As shown, a heater 2 is provided on the outside of the reaction vessel 1. A fixing ring 5 is fixed on the outer wall of the heater 2, and a support 4 is fixed on the outer wall of the fixing ring 5. Specifically, in the diamond micro powder surface coating process, the heater 2 heats the reaction vessel 1 and its internal coating liquid to meet the temperature requirements of the coating process.

[0029] like Figure 1 As shown, a fixing plate 9 is also fixed to the top of the top cover 6. A vibration motor 10 is installed on the top of the fixing plate 9. During the feeding process, the vibration motor 10 is started, and the vibration motor 10 drives the top cover 6 to vibrate. The vibration is transmitted downward through the top cover 6 to the material box 12. During the vibration of the material box 12, the diamond powder inside the material box 12 is vibrated and falls downward, which is conducive to the continuous downward falling of the diamond powder.
