[0020] 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.

[0021] Please see Figures 1-6 As shown, a dynamic airflow separation device for uniformizing iron powder particle size includes a separation box 1, with guide plates 2 arranged crosswise inside the separation box 1, a partition platform 3 inside the separation box 1, and a fan 4 on one side of the separation box 1. The output end of the fan 4 has a blower head 5 for separation. The airflow generated by the fan 4 is blown into the separation box 1 through the blower head 5. Under the action of the airflow, iron powder of different particle sizes is separated due to different forces. The lighter, smaller iron powder is blown towards the partition platform 3, while the heavier, larger iron powder remains in the partition platform 3. On the other side of the separator 3, particle size sorting is completed. Inside the sorting box 1, between the guide plate 2 and the separator 3, there is a cleanable airflow recovery component 6. On the other side of the sorting box 1, there is a vacuum cleaner 7. The output end of the vacuum cleaner 7 is connected to the cleanable airflow recovery component 6, which can purify the airflow and reintroduce the purified airflow into the sorting box 1, reducing airflow waste and energy consumption. On the sorting box 1, on the side of the vacuum cleaner 7, there is a motor 8 for driving the cleanable airflow recovery component 6.

[0022] The cleanable airflow recovery assembly 6 includes a recovery cover 601, a rotating gear 602, and a suction head 603. The recovery cover 601 is mounted on the sorting box 1. The rotating gear 602 is rotatably mounted on the inner wall of the sorting box 1 and is fixedly connected to the output end of the motor 8, so that the rotation of the motor 8 drives the rotating gear 602 to rotate. The suction head 603 is mounted on the inner wall of the sorting box 1. A filter screen 604 is rotatably mounted on one end of the recovery cover 601. The filter screen 604 meshes with the rotating gear 602 and is located below the suction head 603. A cleaning brush 605 is connected to the suction head 603 and contacts the filter screen 604. A suction pipe 606 is connected to the suction head 603, and the other end of the suction pipe 606 is connected to the vacuum cleaner 7. The output end is connected, the motor 8 rotates, driving the rotating gear 602 to rotate the filter screen 604. The cleaning brush 605 contacts the filter screen 604 and brushes off the fine particles attached to the filter screen 604. The vacuum cleaner 7 uses the suction pipe 606 to make the suction head 603 have a certain suction force to suck away the fine particles brushed off, ensuring the cleaning quality of the filter screen 604 and avoiding the filter screen 604 from clogging and affecting airflow recovery. The recovery cover 601 is connected to the return pipe 607, and the other end of the return pipe 607 is equipped with an airflow blower 608. The recovery cover 601 is equipped with an exhaust fan 609. The exhaust fan 609 can guide part of the treated airflow through the return pipe 607 to the airflow blower 608 and blow it back into the sorting box 1 to realize airflow recycling and reduce energy consumption.

[0023] The guide plate 2 is provided with wave-shaped protrusions 9 arranged in an array. Iron powder falls on the cross-arranged guide plate 2. The wave-shaped protrusions 9 cause the iron powder to change direction continuously as it slides down, achieving uniform dispersion, which facilitates air separation. The two sides of the sorting box 1 are fitted with baffles 10. The baffles 10 are provided with handles 11. By pulling the handles 11, the baffles 10 can be removed, thereby removing the sorted iron powder from the inside of the sorting box 1. The lower surface of the sorting box 1 is provided with support feet, and the upper surface of the sorting box 1 is provided with a feed inlet 12. The feed inlet 12 puts the iron powder to be sorted into the inside of the sorting box 1.

[0024] In use, iron powder is fed into the sorting box 1 through the feed inlet 12. The iron powder is evenly dispersed on the guide plate 2, and the wavy protrusions 9 on the guide plate 2 further break up the agglomerates of iron powder, ensuring that the iron powder enters the sorting area in the form of single particles or small particle clusters. The blower 4 is started, causing the blower head 5 to generate a high-speed airflow. The airflow mixes with the iron powder, and the fine particles are carried away by the airflow and enter one side of the separator 3. The coarse particles settle to the other side of the separator 3 due to gravity. The fine particles enter the cleanable airflow recovery component 6 with the airflow. When the airflow passes through the filter screen 604, the fine particles are intercepted by the filter screen 604. The purified airflow passes through the return pipe. 607 and airflow nozzle 608 are reintroduced into the sorting box 1 to achieve airflow recycling. When the filter screen 604 needs to be cleaned, the motor 8 is started, the gear 602 is rotated, and the filter screen 604 is rotated. The cleaning brush 605 contacts the filter screen 604 and brushes off the fine particles attached to the filter screen 604. The vacuum cleaner 7 sucks away the brushed fine particles through the suction pipe 606 to prevent the filter screen 604 from clogging and affecting airflow recovery. After sorting, coarse particles and fine particles are deposited on both sides of the separator 3. The baffles 10 on both sides of the sorting box 1 can be opened by pulling the handle 11 to easily remove the sorted iron powder.
