Description

Technical Field

[0001] This utility model relates to the field of diamond micron powder technology, and in particular to a device for removing impurities from diamond micron powder. Background Technology

[0002] Diamond, as a superhard material, has been widely used in the industrial field due to its excellent properties such as extremely high hardness, excellent wear resistance, good thermal conductivity and chemical stability. However, the preparation process of diamond micro powder is relatively complex, and in practical applications, its purity has a crucial impact on the performance and quality of the product. In the production process of synthetic diamond micro powder, various impurities are inevitably introduced due to limitations of raw materials, synthesis processes and subsequent processing.

[0003] Impurities in diamond micron powder can be broadly classified into two categories: external impurities and internal impurities. Physical separation is typically used to remove external impurities. This method utilizes the difference in physical properties between diamond micron powder and impurities, and the density difference between them, allowing for separation through gravity settling in a settling tank. However, existing settling tanks have shortcomings. After diamond micron powder is added to the settling tank, mechanical stirring is usually used to evenly disperse it in the suspension. However, the stirring structure occupies a large amount of space in the settling tank, preventing the addition of more diamond micron powder during settling, resulting in low settling efficiency. Utility Model Content

[0004] This invention proposes a diamond micro powder impurity removal device to solve the problem that existing stirring structures occupy a large amount of space in the settling tank, affecting the settling efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A diamond micron powder impurity removal device includes a settling tank with an open top and a waste discharge pipe at the bottom. A hopper is located at the top of the settling tank, and a sieve plate is located at the bottom of the hopper. An inlet pipe and a discharge pipe are inserted downwards into the top of the sieve plate. The extension end of the discharge pipe extends downwards into the interior of the settling tank. A nozzle assembly is located inside the settling tank. The nozzle assembly includes a partition plate, a main nozzle is located on one side wall of the partition plate, and a secondary nozzle is located below the main nozzle. The main nozzle is connected to a main air inlet pipe, and the secondary nozzle is connected to a secondary air inlet pipe. The extension ends of the main and secondary air inlets extend to the outside of the settling tank.

[0007] Preferably, the bottom end of the main nozzle has a downwardly inclined exhaust port, and the bottom end of the auxiliary nozzle has a horizontally arranged air outlet.

[0008] Preferably, trays are fixed to the bottom of both ends of the hopper, a vibrating motor is fixed to the bottom of the trays, and a mounting base is provided on one side of the vibrating motor.

[0009] Preferably, the bottom of the mounting base is provided with a sliding plate, the bottom of the settling trough is provided with a base, and the top side of the base is provided with a slide rail, and the bottom of the sliding plate can slide horizontally on the top of the slide rail.

[0010] Preferably, the bottom end of the discharge pipe is provided with multiple branch pipes, and each branch pipe has a through hole on its outer wall.

[0011] Preferably, the bottom of the auxiliary nozzle is provided with a support frame, the bottom of the main nozzle is provided with a groove, and the air outlet end of the auxiliary nozzle is disposed in the groove.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] By installing a nozzle assembly inside the settling tank, with the air inlet pipe of the nozzle assembly extending to the outside of the settling tank, gas is input into the air inlet pipe through an external air pump. The gas is then sprayed from the nozzle assembly into the interior of the settling tank, where the suspension and diamond powder are thoroughly mixed through air jetting. The nozzle assembly does not occupy a large amount of space inside the settling tank, and the exhaust port of the main nozzle of the nozzle assembly is set downwards, allowing the gas to be sprayed to the bottom of the settling tank and form bubbles. As the bubbles rise and the gas flow rate increases, it gradually transforms into a turbulent state, which is beneficial for the dispersion of diamond powder and avoids the problem of diamond powder agglomeration, thereby improving the settling efficiency.

[0025] 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.

[0026] This utility model provides, for example Figures 1-9 The diamond micro powder impurity removal device shown includes a settling tank 9 with an open top. A waste discharge pipe 13 is provided at the bottom of the settling tank 9. A hopper 1 is provided at the top of the settling tank 9. A sieve plate 5 is provided at the bottom of the hopper 1. An inlet pipe 3 and a discharge pipe 4 are inserted downwards at the top of the sieve plate 5. The extension end of the discharge pipe 4 extends downwards into the interior of the settling tank 9. A nozzle assembly is provided inside the settling tank 9. The nozzle assembly includes an isolation plate 14. A main nozzle 17 is provided on one side wall of the isolation plate 14. A secondary nozzle 18 is provided below the main nozzle 17. The main nozzle 17 is connected to a main air inlet pipe 10. The secondary nozzle 18 is connected to a secondary air inlet pipe 11. The extension ends of the main air inlet pipe 10 and the secondary air inlet pipe 11 extend to the outside of the settling tank 9.

[0027] In this embodiment, sedimentation is used to remove impurities. The sedimentation method is mainly based on the principle of gravity sedimentation, that is, to achieve classification by utilizing the difference in sedimentation velocity between diamond powder and other impurities in the suspension.

[0028] It should be noted that before cleaning impurities, a suspension needs to be prepared according to the density difference between the diamond powder and the impurities therein. The suspension should meet the following conditions: the diamond powder can float in the suspension or float on the surface of the suspension, and the impurities should settle at the bottom of the suspension after a period of settling.

[0029] The suspension enters the settling tank 9 through the inlet pipe 3, and the diamond powder falls into the settling tank 9 after passing through the sieve plate 5. The main air inlet pipe 10 and the auxiliary air inlet pipe 11 are respectively connected to an external high-pressure air pump. The high-pressure gas is discharged from the exhaust port 171 of the main nozzle 17 through the main air inlet pipe 10. The high-pressure gas is injected into the suspension, so that the suspension and the diamond powder can be fully mixed. At the same time, the high-pressure gas is also ejected from the auxiliary nozzle 18, which can spray gas in a horizontal direction. The gas injected into the settling tank 9 in different directions makes the suspension inside the settling tank 9 turbulent, which can further make the diamond powder evenly dispersed in the suspension, avoid the problem of diamond powder agglomeration, and thus improve the settling efficiency.

[0030] After settling, impurities accumulate at the bottom of the settling tank 9. The external pump body connects to the discharge pipe 4 to extract the suspension and diamond powder. The suspension and diamond powder can be extracted from the settling tank 9. Then, the external pump body (not shown in the figure) connects to the waste discharge pipe 13 to extract the impurities at the bottom of the settling tank 9. The impurities are discharged through the waste discharge pipe 13, which is beneficial for cleaning the impurities and the bottom of the settling tank 9.

[0031] like Figure 7 As shown, the bottom end of the main nozzle 17 is provided with an inclined downward exhaust port 171, and the bottom end of the auxiliary nozzle 18 is provided with a horizontally arranged air outlet. High-pressure gas enters the main nozzle 17 through the main air inlet pipe 10. The gas flows downward and towards the bottom of the settling tank 9, forming bubbles at the bottom of the settling tank 9. As the bubbles flow upward, they will disperse the diamond powder, which can prevent the diamond powder from clumping in the suspension.

[0032] like Figure 1 , Figure 8 and Figure 9 As shown, trays 61 are fixed at the bottom of both ends of the hopper 1, and a vibration motor 6 is fixed at the bottom of the tray 61. A mounting base 2 is provided on one side of the vibration motor 6. When the vibration motor 6 is started, the vibration motor 6 drives the tray 61 to vibrate. The tray 61 transmits the vibration to the hopper 1. The diamond powder above the screen plate 5 is vibrated and falls downward. At this time, the agglomerated diamond powder is shaken apart, which makes it easier to feed the material evenly into the settling tank 9.

[0033] like Figure 1 and Figure 2As shown, a sliding plate 8 is provided at the bottom of the mounting base 2, and a base 7 is provided at the bottom of the settling tank 9. A slide rail 15 is provided on one side of the top of the base 7. The bottom of the sliding plate 8 can slide horizontally on the top of the slide rail 15. During the process of removing the hopper 1, by pulling one of the mounting bases 2 horizontally, the sliding plate 8 at the bottom of the mounting base 2 slides on the slide rail 15. After the mounting base 2 is removed, the end of the hopper 1 is exposed to the outside. By pulling out one end of the hopper 1, the other end can be pulled out from the other mounting base 2, thereby removing the hopper 1 from the top of the settling tank 9. The opening of the settling tank 9 is exposed to the outside, which facilitates the cleaning of the internal space structure of the settling tank 9.

[0034] like Figure 2 As shown, the bottom end of the discharge pipe 4 is provided with multiple branch pipes 12. Each branch pipe 12 has a through hole on its outer wall. The top end of the discharge pipe 4 is connected to an external pipeline through a flange. Diamond powder in the settling tank 9 can be extracted by a diaphragm pump. The diamond powder extracted at this time is diamond powder that has already settled. Impurities are located at the bottom of the settling tank 9. An external lifting mechanism can be installed outside the settling tank 9. The lifting mechanism drives the discharge pipe 4 and the branch pipes 12 to lift and lower, so that diamond powder at different positions in the settling tank 9 can be extracted.

[0035] like Figure 2 and Figure 4 As shown, a support frame 16 is provided at the bottom of the auxiliary nozzle 18, and a groove 19 is provided at the bottom of the main nozzle 17. The air outlet of the auxiliary nozzle 18 is located in the groove 19. Specifically, the support frame 16 supports the isolation plate 14, the auxiliary nozzle 18 and the main nozzle 17, ensuring the stability of the isolation plate 14, the main nozzle 17 and the auxiliary nozzle 18. The isolation plate 14, the main nozzle 17 and the auxiliary nozzle 18 will not tip over due to liquid flow in the settling tank 9.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
