[0023] The air pump 4 is connected to the blow pipe 5 through a pipeline, and the feeding hopper 6 and the end cover 7 are slidingly arranged to facilitate the air pump 4 to blow air toward the blow pipe 5, so that the air flow blown out from the blow pipe 5 is used to sort the materials, and to facilitate the end cover 7 to cover the feeding hopper 6, thereby sealing the feeding hopper 6 and preventing foreign matter from entering the interior when the device stops working.

[0024] The limiting sleeve 8 and the square rod 9 are slidably connected, the clamp 10 and the end cover 7 are slidably arranged, and the side outer wall of the clamp 10 is connected to the outer wall of the limiting sleeve 8 through the spring 11, and the positive cross-section shape of the clamp 10 is set to be "L" shape, which is convenient for elastic support of the clamp 10 by the spring 11, and convenient for the user to move the square rod 9, so that the square rod 9 drives the clamp 10 to disengage from the end cover 7, thereby facilitating the user to disassemble and assemble the end cover 7.

[0025] The ventilation mechanism 12 includes a filter cover 1201, a filter screen 1202 and a sealing gasket 1203, and the filter cover 1201 is slidably installed on the inner wall of the sorting box 1, and the filter screen 1202 is fixedly provided on the inner wall of the lower end of the filter cover 1201, and the sealing gasket 1203 is bonded to the outer wall of the filter cover 1201, so as to facilitate the exhaust of the device through the ventilation mechanism 12.

[0026] The filter cover 1201 and the card plate 13 are in close contact with each other, and the card plate 13 and the sorting box 1 form a rotating structure. The sealing gasket 1203 and the sorting box 1 are in close contact with each other, which makes it convenient to limit the filter cover 1201 by the card plate 13 and to rotate the card plate 13 relative to the sorting box 1.

[0028] Working principle: When using the airflow classification silicon carbide powder classification device, first Figure 1-2 As shown, the user starts the air pump 4, and the gas is pumped into the blowpipe 5 through the air pump 4 and blown out through the blowpipe 5. Then the user pours the silicon carbide micropowder to be processed into the feeding hopper 6. Next, the silicon carbide micropowder falls on the baffle 15 and flows down along the baffle 15. Then the blowpipe 5 blows air towards the falling silicon carbide micropowder. At this time, the large-mass silicon carbide micropowder falls into the left material tank 2, and the small-mass silicon carbide micropowder falls into the right material tank 3 under the action of the airflow, thereby completing the airflow classification of the silicon carbide micropowder, and then as shown in FIG. Figure 1 and Figure 3-5As shown, the ventilation mechanism 12 discharges the gas in the sorting box 1, and the filter 1202 filters the gas. When the filter 1202 needs to be removed for cleaning, the user stops the air pump 4, and then the user pulls the clamping rod 14. Next, the clamping rod 14 moves relative to the clamping plate 13 and separates from the sorting box 1. At the same time, the clamping rod 14 compresses the spring 11 and deforms. Then, the user rotates the clamping plate 13 so that the clamping plate 13 separates from the filter cover 1201. Then, the user pulls out the filter cover 1201 on the sorting box 1. At this time, the sealing gasket 1203 separates from the sorting box 1, and the filter 1202 is away from the device, so that it is convenient for the user to clean the filter. 1202, so the device is easy to disassemble the filter 1202 for cleaning, thereby avoiding the accumulation of materials on the filter 1202 affecting the normal use of the filter 1202, and then when the device stops working, the user pulls the square rod 9, at this time the square rod 9 moves relative to the limit sleeve 8 and the compression spring 11 is deformed, then the user puts the end cover 7 on the feeding hopper 6 and loosens the square rod 9, then the spring 11 resets and pushes the card 10 to move so that the card 10 moves the end cover 7, thereby limiting the end cover 7, at this time the end cover 7 seals the feeding hopper 6 to avoid foreign matter from entering the interior of the device through the feeding hopper 6 when the device stops working.
