Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for diamond production, specifically to a micro powder impurity removal device for diamond production. Background Technology

[0002] Diamond, commonly known as "diamond," is a mineral composed of carbon. It is an allotrope of graphite with the chemical formula C. It is also the original form of diamond and is the hardest naturally occurring substance in nature.

[0003] In the diamond production process, it is necessary to make diamond powder. However, during the production of diamond powder, impurities and powder that does not meet the required size are often mixed in. The traditional method is to use filtration to remove impurities. If a single layer of filtration is used, it can only filter out impurities above a certain size range. Therefore, multi-layer filtration is often used to filter out the desired powder size range. However, for such fine dust, the filtration efficiency is low and the filter element is often clogged. Utility Model Content

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Combined with appendix Figure 1-4 A micro powder impurity removal device for diamond production includes a removal box body 1 and an air filter box 15. The removal box body 1 has a feeding port 3 at the top and a discharge port 4 at the bottom. The top of the removal box body 1 has an inclined filter screen 2, as shown in the figure. The feeding port 3 is located above the higher end of the filter screen 2, which can ensure that the diamond micro powder can be fully filtered. The bottom of the removal box body 1 has a removal channel 5 that communicates with the discharge port 4. The removal box body 1 has a discharge port 16 on the lower side of the filter screen 2. A storage box 17 that matches the discharge port 16 is located on one side of the removal box body 1. Larger impurities filtered by the filter screen 2 will enter the storage box 17 through the discharge port 16. The discharged impurities can also be taken out and re-entered into the removal box body 1 for filtration and impurity removal.

[0022] The main body 1 of the impurity removal box is equipped with guide plates 7 above the impurity removal channel 5, as shown in the figure. The guide plates 7 on both sides guide the material to the middle of the impurity removal channel 5, which can ensure that the material can fall from the middle position of the impurity removal channel 5. At the same time, the space between the guide plates 7 on both sides should not be too large, otherwise the material is prone to parabolic trajectory when falling from the guide plates 7, thus moving away from the middle position. Shortening the space can reduce the occurrence of this situation. The main body 1 of the impurity removal box is equipped with air inlet channel 10 and air outlet channel 11 on both sides of the impurity removal channel 5. One side of the main body 1 of the impurity removal box is equipped with an air inlet structure 8 that communicates with the air inlet channel 10 and the air filter box 15, and the other side is equipped with an exhaust structure 9 that communicates with the exhaust channel 11. That is, the air inlet structure 8 and the exhaust structure 9 can ensure that the air inlet channel 10 and the exhaust channel 11 form a convection channel. By adjusting the wind speed, impurity removal can be performed.

[0023] The main body 1 of the impurity removal box is provided with a vibration structure 6 below the filter screen plate 2. The vibration structure 6 includes a rotating shaft 12 rotatably disposed below the filter screen plate 2. A vibration cam 13 is provided on the rotating shaft 12. A drive motor 14 is provided on the outside of the main body 1 of the impurity removal box to drive the rotating shaft 12 to rotate. The drive motor 14 drives the rotating shaft 12 and the vibration cam 13 to rotate, thereby vibrating the filter screen plate 2 and thus accelerating the filtration efficiency of the filter screen plate 2.

[0024] Both the air inlet structure 8 and the exhaust structure 9 include an air collecting duct 18, an exhaust fan structure 19, and an air guiding duct 20. The air collecting duct 18 is connected to the air inlet channel 10 and the impurity discharge channel 11. The air guiding duct 20 of the air inlet structure 8 is connected to the air filter box 15. The exhaust fan structure 19 includes a fan housing 21, a rotating shaft 22 is rotatably mounted inside the fan housing 21, and a fan blade 23 is welded to the outside of the rotating shaft 22. A servo motor 24 that drives the rotating shaft 22 is mounted outside the fan housing 21. The exhaust fan structure 19 can perform exhaust operations. In actual design, the air guiding duct 20 of the exhaust structure 9 needs to be connected to an external impurity collection device for convenient downstream collection operations. At the same time, a wind speed sensor can be installed inside the air guiding duct 20. The wind speed can be adjusted according to the wind speed sensor and the servo motor 24 to adjust the air speed of the inlet and outlet, thereby adjusting the operation according to the different diamond micro powder size requirements.

[0025] The air filter box 15 is provided with a support plate 25. The bottom of the support plate 25 is provided with a dust filter cylinder 26. The dust filter cylinder 26 is generally an internal mesh cylinder structure and an externally sealed filter cloth cover structure that can filter dust, such as non-woven fabric. The bottom of one side of the air filter box 15 is provided with an air inlet 27, and a filter screen 28 is provided inside the air inlet 27.

[0026] 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.
