Description

Technical Field

[0001] This utility model relates to the field of diamond micron powder classification technology, and more specifically, to a multi-level classification device for diamond micron powder particles. Background Technology

[0002] Diamond, commonly known as "diamond," is a mineral composed of carbon. It is an allotrope of carbon and a particle composed of a single element in nature. It is the hardest naturally occurring substance found on Earth. Diamond powder is a further product of diamond, and a grading device is used in the production process to produce diamond powder.

[0003] When existing grading devices need to classify diamond powder, they first start the hollow shaft motor. The hollow shaft motor drives the rotating rod and fan blades to rotate at high speed, generating a strong upward swirling flow. The air-collecting bucket gathers the swirling flow, allowing the diamond particles to smoothly reach the collection bucket through the small holes on the rotating rod wall. The whole process requires multiple sets of motors, resulting in a large amount of energy consumption and resource waste.

[0004] A search revealed a Chinese patent, CN215744756U, which discloses a rotary vibration classifying device for the production of micron-sized diamond powder. This invention involves the diamond powder undergoing a projectile motion after entering the chamber. Larger diamond powder particles, with greater mass and higher initial velocity, fall into the discharge hopper located further from the feed inlet. Conversely, smaller diamond powder particles, with lower mass and lower initial velocity, fall into the discharge hopper located closer to the feed inlet. The entire diamond powder classification process does not consume excessive energy, thus conserving resources.

[0005] However, in actual use, the above-mentioned grading device classifies and sieves diamond micro powder through airflow. The uniform airflow blowing the diamond micro powder particles can cause some agglomeration between the diamond micro powder particles, which will reduce the accuracy of diamond micro powder grading. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-stage classification device for diamond micron powder particles to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multi-stage grading device for diamond micron powder includes a housing. A support is fixedly connected to the bottom of the housing, and multiple collection boxes are slidably connected to the inner side of the support. A support frame is fixedly connected to the top of the housing. Two fans are installed on one side of the housing, and air ducts are fixedly connected to the output ends of the fans. A grading and collection mechanism is provided inside the housing. The grading and collection mechanism includes a first collection frame, a second collection frame fixedly connected to one side of the first collection frame, and the bottom of the second collection frame fixedly connected to the inner side of the housing. Multiple dispersion plates are fixedly connected to the inner side of the first collection frame, and multiple dispersion plates are fixedly connected to the inner side of the second collection frame. Multiple dispersing plates are fixedly connected. One side of the first dispersing plate is fixedly connected to one side of the second dispersing plate. One end of the air duct is fixedly connected to the inner side of the first concentrator frame. The outer side of the air duct is fixedly connected to the inner side of the outer shell. Multiple hoppers are fixedly connected to the bottom of the outer shell. Three partitions are fixedly connected to the inner side of the outer shell. An inclined plate is fixedly connected to the top of the partitions. Two air outlet pipes are fixedly connected to one side of the outer shell. A filter plate is fixedly connected to the top of the air outlet pipe. A filter plate is slidably connected to the inner side of the air outlet pipe. A handle is fixedly connected to one side of the filter plate. A dispersing mechanism is provided on the inner side of the outer shell.

[0009] By adopting the above technical solution: multiple dispersion plates one and two disperse the airflow to blow and disperse the falling diamond powder particles, and output and circulate the airflow inside the shell through two air outlet pipes, and filter plates one and two filter plates filter the output airflow to prevent diamond powder particles from escaping from the inside of the shell.

[0010] As a further description of the above technical solution: the dispersing mechanism includes a servo motor, the outer side of which is fixedly connected to the inner side of the support frame, a rotating base fixedly connected to the output end of the servo motor, multiple arc-shaped plates fixedly connected to the outer side of the rotating base, a grinding ball fixedly connected to the bottom of the rotating base, a feed hopper fixedly connected to the outer side of the outer shell, a grinding seat fixedly connected to the inner side of the outer shell, multiple fixing blocks fixedly connected to the inner side of the outer shell, a sliding rod slidably connected to the inner side of the fixing block, a spring sleeved on the outer side of the sliding rod, the bottom end of the spring fixedly connected to the top of the fixing block, a vibration frame fixedly connected to the top of the sliding rod, and a vibration motor fixedly connected to the bottom of the vibration frame.

[0011] By adopting the above technical solution: grinding diamond micro powder particles with grinding balls and grinding base, and vibrating diamond micro powder particles with a vibrating frame, the diamond micro powder particles can be dispersed and moved to one side and scattered.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By setting up a graded collection mechanism, compared with the existing technology, multiple dispersion plates one and two are used to stratify the flow velocity of the airflow, so that the airflow is dispersed, reducing the agglomeration of diamond micro powder particles and avoiding local accumulation of diamond micro powder particles due to uneven airflow. At the same time, two air outlet pipes, filter plates one and two are used to filter the output airflow, preventing diamond micro powder particles from being carried into the external environment by the airflow, thus improving the accuracy and environmental friendliness of diamond micro powder particle grading.

[0014] By setting up a dispersion mechanism, compared with the existing technology, the diamond micro powder particles are further ground by the rotational friction of the grinding balls and grinding seat, and the diamond micro powder particles are evenly sprinkled to the sorting inlet by the vibration of the vibrating frame, avoiding local accumulation, reducing the energy consumption of the dispersion airflow in the subsequent airflow classification, and optimizing the use efficiency of the multi-stage classification device.

A grading and collection mechanism is provided inside the shell 1. The grading and collection mechanism includes a first collection frame 7, a second collection frame 8 fixedly connected to one side of the first collection frame 7, the bottom of the second collection frame 8 fixedly connected to the inner side of the shell 1, multiple first dispersion plates 9 fixedly connected to the inner side of the first collection frame 7, multiple second dispersion plates 10 fixedly connected to the inner side of the second collection frame 8, one side of the first dispersion plate 9 and one side of the second dispersion plate 10 fixedly connected, one end of the air duct 6 fixedly connected to the inner side of the first collection frame 7, and the outer side of the air duct 6 fixedly connected to the inner side of the shell 1, multiple discharge hoppers 11 fixedly connected to the bottom of the shell 1, and three partitions 12 fixedly connected to the inner side of the shell 1. An inclined plate 13 is fixedly connected to the top, and two air outlet pipes 14 are fixedly connected to one side of the outer shell 1. A filter plate 15 is fixedly connected to the top of the air outlet pipe 14, and a filter plate 16 is slidably connected to the inner side of the air outlet pipe 14. A handle 17 is fixedly connected to one side of the filter plate 16. A dispersion mechanism is provided inside the outer shell 1. The fan 5 and the air pipe 6 are used to input airflow into the interior of the first and second collection frames 7 and 8, and multiple dispersion plates 9 and 10 are used to disperse the airflow, so that the airflow can blow the scattered diamond powder particles, so that the diamond powder particles fall from the hopper 11 in the middle of the outer shell 1 to the hopper 11 on one side of the outer shell 1 from heavy to light. After the diamond powder particles are classified, they fall into the collection box 3 through the hopper 11. By pulling the filter plate 16, the diamond powder particles adsorbed on one side of the filter plate 16 can fall along one side of the air outlet pipe 14 into the nearest hopper 11.

[0025] Reference Figure 1 , Figure 4 and Figure 5As shown, the dispersing mechanism includes a servo motor 18, the outer side of which is fixedly connected to the inner side of the support frame 4. A rotating base 19 is fixedly connected to the output end of the servo motor 18. Multiple arc-shaped plates 20 are fixedly connected to the outer side of the rotating base 19. Grinding balls 21 are fixedly connected to the bottom of the rotating base 19. A feed hopper 22 is fixedly connected to the outer side of the outer shell 1. A grinding seat 23 is fixedly connected to the inner side of the outer shell 1. Multiple fixing blocks 24 are fixedly connected to the inner side of the outer shell 1. A sliding rod 25 is slidably connected to the inner side of the fixing block 24. A spring 26 is sleeved on the outer side of the sliding rod 25. The bottom end of the spring 26 is connected to the fixed... The top of block 24 is fixedly connected, and the top of slide rod 25 is fixedly connected to a vibration frame 27. The bottom of vibration frame 27 is fixedly connected to a vibration motor 28. Servo motor 18 drives rotating seat 19 and arc plate 20 to stir the diamond micro powder particles gathered inside feed hopper 22, so that the diamond micro powder particles can continuously move into the interior of grinding seat 23. The grinding balls 21 and grinding seat 23 are used to grind the diamond micro powder particles. The vibration motor 28 drives vibration frame 27 to vibrate, disperse and sprinkle the diamond micro powder particles.

[0026] The working principle of this invention is as follows: Before classifying the diamond micro-powder particles, the diamond micro-powder particles are first placed inside the feed hopper 22. A servo motor 18 drives a rotating base 19 and multiple arc-shaped plates 20 to agitate the diamond micro-powder particles inside the feed hopper 22, causing them to move towards the bottom of the grinding seat 23. The servo motor 18 then drives the grinding balls 21 to rotate inside the grinding seat 23, allowing the diamond micro-powder particles to be ground by the rotational friction between the inner wall of the grinding balls 21 and the grinding seat 23. After grinding and feeding, the diamond micro powder particles fall from the bottom of the grinding seat 23 to the top of the vibrating frame 27. Then, the vibrating motor 28 drives the vibrating frame 27 to vibrate up and down. With the support of multiple springs 26 at the bottom of the vibrating frame 27 and the sliding rod 25 sliding inside the fixed block 24, the vibrating frame 27 can vibrate up and down inside the outer shell 1. Then, through the vibration of the vibrating frame 27 on the diamond micro powder particles, the diamond micro powder particles can move at a uniform speed to one side of the vibrating frame 27 and fall to the bottom of the outer shell 1.

[0027] Then, the two fans 5 input a large air force into the interior of the first and second concentration frames 7 and 8 through the air duct 6. The air is guided by multiple dispersion plates 9 and 10 on the inner side of the first and second concentration frames 7 and 8. The air then blows into the interior of the outer shell 1 through one side of the second concentration frame 8. The air then blows the diamond powder particles scattered by the vibrating frame 27, causing the diamond powder particles to flow to the other side of the outer shell 1 according to their own mass from light to heavy. The particles are then blocked and guided by the three partitions 12 and the inclined plate 13, so that... Diamond micro powder particles fall into multiple hoppers 11 at the bottom of the outer shell 1 according to their weight from heaviest to lightest. The hoppers 11 then guide the diamond micro powder particles into the collection box 3. Finally, the air entering the outer shell 1 is output from the two air outlets 14 on the other side of the outer shell 1 to the outside of the outer shell 1. The diamond micro powder particles mixed in the air are filtered by filter plate 15 and filter plate 16. The filter plate 16 can be removed from the air outlet 14 for cleaning by pulling the handle 17.
