Description

Technical Field

[0001] This utility model relates to the technical field of diamond micron powder processing equipment, specifically to an integrated device for dispersing and sieving micron-level diamond micron powder. Background Technology

[0002] Diamond micron powder is widely used in precision grinding and polishing due to its high hardness and wear resistance. Its particle size uniformity directly affects the product processing quality. Micron-sized diamond micron powder is prone to agglomeration due to van der Waals forces and electrostatic forces during production and storage, and needs to be dispersed and sieved to achieve graded purification. In existing technologies, the dispersing and sieving of diamond micron powder are mostly done with separate equipment or simple integrated structures, which only use mechanical stirring or single airflow impact, making it difficult to break up hard agglomerates and resulting in incomplete dispersing. Subsequent sieving is prone to screen blockage due to agglomerates. At the same time, the micron-sized screen has a small pore size and strong adsorption force of micron powder, and conventional vibrating screens cannot effectively clean the screen pores, resulting in a continuous decline in sieving efficiency. Furthermore, coarse material that does not pass through the screen is directly discharged without secondary dispersing, causing waste of raw materials. Therefore, we propose an integrated device for dispersing and sieving micron-sized diamond micron powder. Utility Model Content

[0003] In view of the problems existing in the above-mentioned integrated device for dispersing and sieving micron-sized diamond powder, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide an integrated device for dispersing and sieving micron-sized diamond powder. This solves the problem that in the prior art, the dispersing and sieving of diamond powder is mostly done by separate equipment or simple integrated structures, which only use mechanical stirring or single airflow impact, making it difficult to break up hard agglomerates and resulting in incomplete dispersing. Subsequent sieving is prone to clogging of the screen due to agglomerates. At the same time, the micron-sized screen has a small pore size and strong adsorption force of micron-sized powder, and conventional vibrating sieving cannot effectively clean the screen pores, resulting in a continuous decline in sieving efficiency. Furthermore, coarse material that does not pass through the screen is directly discharged without secondary dispersing, causing waste of raw materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An integrated device for dispersing and sieving micron-sized diamond powder includes a sealed shell, a fine material collection hopper, and a return pipe. A feed pipe is fixedly installed at the top of the sealed shell, and a fine material collection hopper is fixedly installed at the bottom of the sealed shell. Fixed columns are fixedly installed on both sides inside the sealed shell, and conical dispersion hoods are fixedly installed at the bottom of the two fixed columns.

A first gear is fixedly installed on the surface of the rotating shaft. A gear ring is fixedly installed inside the sealed shell, and second gears are meshed on both sides of the gear ring. The two second gears are respectively meshed with the first gear.

[0008] Preferably, one side of each of the multiple screens is provided with a conveying pipe that penetrates the sealed housing, and a return pipe is fixedly installed on the outer side of the sealed housing. Both of the conveying pipes are connected to one side of the return pipe, and a screw feeder is rotatably provided inside the return pipe.

[0010] Preferably, the feed pipe is provided with spiral guide vanes inside, and a hot air inlet channel is provided on one side of the feed pipe.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model adopts a three-stage dispersion structure of pre-dispersion, mechanical stirring and dispersion, and airflow and ultrasonic synergistic dispersion. Compared with the existing single dispersion method, it can simultaneously break up soft and hard agglomerates, significantly improve the uniformity of dispersion, and effectively solve the technical pain point of incomplete dispersion in existing devices. At the same time, through the combined design of spring elastic support, ultrasonic vibration and reverse blowing, on the one hand, the ultrasonic vibration enhances the screening ability of the screen, and on the other hand, the reverse blowing cleans the screen pores, fundamentally solving the problem that micron-level screens are prone to clogging due to micro powder adsorption, resulting in a continuous decline in screening efficiency, and ensuring long-term operational stability.

[0012] 2. This utility model, by setting up a closed-loop reflux system, allows substandard coarse materials to be returned to the feed end for secondary processing via a reflux pipe and screw feeder. This avoids the waste of raw materials caused by the direct discharge of coarse materials in the prior art, greatly improves the utilization rate of raw materials, and reduces production losses. At the same time, it integrates the functions of pre-dispersion, dispersing, screening, reflux, and collection into a sealed shell, which is compact in structure, occupies a small area, and does not require the additional configuration of multiple separate devices, simplifying the operation process.

Fixed columns 5 are fixedly installed on both sides inside the sealed shell 1. A conical dispersion hood 6 is fixedly installed at the bottom of the two fixed columns 5. A motor 7 is fixedly installed at the bottom of the conical dispersion hood 6. A rotating shaft 8 is fixedly installed at the output end of the motor 7. A first gear 9 is fixedly installed on the surface of the rotating shaft 8. A gear ring 10 is fixedly installed inside the sealed shell 1. Second gears 11 are meshed on both sides of the gear ring 10. The two second gears 11 are respectively meshed with the first gear 9. A stirring shaft 12 is provided at the bottom of the two second gears 11. Stirring blades 13 are alternately arranged on the surfaces of the rotating shaft 8 and the two stirring shafts 12 to apply shearing and impact forces to the pre-dispersed material, effectively breaking down hard agglomerates.

[0019] This utility model discloses an integrated device for dispersing and sieving micron-level diamond powder. The sealed housing 1 has an annular airflow cavity 14 fixedly installed inside. Multiple airflow nozzles 15 are fixedly installed on the surface of the annular airflow cavity 14. An ultrasonic transducer 16 is provided on the outer wall of the annular airflow cavity 14. An air inlet 17 is provided through one side of the annular airflow cavity 14, which can form an airflow field surrounding the material and drive the material to further collide and disperse.

[0020] This utility model discloses an integrated device for dispersing and sieving micron-sized diamond powder. Multiple support plates 18 are fixed on both sides of the bottom of the sealed housing 1. Springs 19 are fixedly installed on the top of each of the multiple support plates 18. Screens 20 are fixedly installed on the top of two opposing springs 19. Ultrasonic vibrators 21 are fixedly installed on the bottom of each of the multiple screens 20 to accelerate the penetration of micron-sized powder that meets the particle size requirements through the screens, while inhibiting the adsorption of micron-sized powder.

[0021] This utility model discloses an integrated device for dispersing and sieving micron-level diamond powder. One side of each of the multiple screens 20 is provided with a conveying pipe 22 that penetrates a sealed housing 1. A return pipe 3 is fixedly installed on the outside of the sealed housing 1. Both conveying pipes 22 are connected to one side of the return pipe 3. A spiral feeder 23 is rotatably installed inside the return pipe 3 to push coarse material to the sealed housing 1, so that it can re-participate in the dispersing and sieving process and realize resource recycling.

[0022] This utility model discloses an integrated device for dispersing and sieving micron-level diamond powder. The bottom of each of the two screens 20 is provided with a blowing chamber 24, and one side of each of the two blowing chambers 24 is provided with an air pipe 25 to blow the screens 20 in reverse to clean the micron-level powder blocking the pores and achieve self-cleaning of the screens 20.

[0023] This utility model discloses an integrated device for dispersing and sieving micron-level diamond powder. The feed pipe 4 is equipped with a spiral guide vane 26 inside, and a hot air inlet channel 27 is provided on one side of the feed pipe 4 to initially break up the soft agglomerates formed by van der Waals forces and electrostatic forces of the powder.

[0024] In use, the micron-sized diamond powder to be processed is fed into the feed pipe 4. The spiral guide vanes 26 inside the feed pipe 4 generate shear force when pushing the material, while hot air is introduced into the hot air inlet channel 27. The two work together to initially break up the soft agglomerates formed by van der Waals forces and electrostatic forces in the powder. After the material is further dispersed by the conical dispersion hood 6, it enters the subsequent dispersing area evenly to avoid local accumulation that affects the dispersing effect.

The stirring blades 13, which are staggered on the surface of the shaft 8 and the stirring shaft 12, apply shear and impact forces to the pre-dispersed material, effectively breaking up hard agglomerates. Then, the annular airflow chamber 14 introduces high-pressure airflow through the air inlet 17 and sprays it out through the airflow nozzles 15 that are evenly distributed on the surface, forming an airflow field around the material, which drives the material to further collide and disperse. At the same time, the annular airflow chamber 14... The ultrasonic transducer 16 on the side wall generates high-frequency vibration, which, in conjunction with the airflow impact, completely breaks down residual agglomerates, preventing secondary agglomeration. The broken-down material naturally falls onto the surface of the screen 20. The screen 20 is elastically supported by the spring 19 at the top of the support plate 18. The ultrasonic vibrator 21 at the bottom drives the screen 20 to vibrate at high frequency, accelerating the penetration of micro-powder that meets the particle size requirements through the screen 20, while inhibiting micro-powder adsorption. The blowing chamber 24 below the screen 20 introduces gas through the air pipe 25 to clean the screen 20. 0 performs reverse blowing to clean the micro powder clogging the pores, achieving self-cleaning of screen 20 and ensuring stable screening efficiency; multi-layer screen 20 performs graded screening to ensure uniform particle size; coarse material that does not pass through screen 20 flows into return pipe 3 through conveying pipe 22, and the screw feeder 23 in return pipe 3 pushes the coarse material to feed pipe 4 to participate in the dispersing and screening process again, realizing resource recycling; qualified micro powder after being screened by screen 20 falls into fine material collection hopper 2 at the bottom of sealed shell 1 to complete the collection operation.
