[0002] One of them is the cyclone separator, which is a device used for separation of gas-solid system or liquid-solid system. The working principle is that the solid particles or liquid droplets with large inertial eccentricity are thrown to the outer wall and separated by the rotational motion caused by the tangential introduction of airflow. It is a separation device widely used in industry.

[0003] Micro powder materials need to go through the step of wind classification during the classification or impurity removal process. During wind classification, the micro powder needs to be poured into the feed port for feeding. However, a large amount of dust will be generated during the feeding and escape from the feed port, thus affecting the workshop environment and the health of the workers. Summary of the invention

During this process, the suction component 3 in the storage box 21 absorbs the dust in the storage box 21 through the suction port 211, and the dust is quickly absorbed, thereby reducing the possibility of the dust spreading outside the storage box 21, thereby protecting the working environment and the health of the workers, and also reducing the possibility of material waste.

At the same time, the second limiting member 6 opens the air exhaust port 213, and the air on the side of the wind shield 31 close to the air exhaust port 213 is discharged through the air exhaust port 213. This cycle is repeated, so that the dust in the storage box 21 is driven by the airflow into the air duct 212, enters the air exhaust port 213 along the airflow, and is collected by the filter bag.

[0036] Reference Figure 2 and Figure 3 The driving assembly 4 includes a driving rod 41, which is slidably connected to the material storage box 21. One end of the driving rod 41 is fixedly connected to an arc rod, and the arc rod is fixed to the wind shield 31.

A driving bevel gear 45 rotatably connected to the material storage box 21 is meshed on the transmission bevel gear 44. A driving member connected to the driving bevel gear 45 is also provided in the material storage box 21.

[0037] The driving member drives the driving bevel gear 45 to rotate, and drives the transmission bevel gear 44 to rotate. The transmission bevel gear 44 drives the driving rod 41 to move through the connecting rod 42. The driving rod 41 slides back and forth relative to the storage box 21, thereby driving the windshield plate 31 to reciprocate.

[0038] The driving member includes an auger 46 rotatably connected to the feed pipe 22. A driving motor 47 is provided on the cyclone separator body 1 to drive the auger 46 to rotate. A rotating shaft is coaxially arranged at one end of the auger 46 away from the driving motor 47. The rotating shaft is connected to the center of the driving bevel gear 45 through a universal joint. The driving motor 47 drives the auger 46 to rotate. The auger 46 cooperates with the wind force to transport the materials in the storage box 21 to the cyclone separator body 1. At the same time, the auger 46 drives the rotating shaft to rotate. The rotating shaft drives the driving bevel gear 45 to rotate through the universal joint, providing power for the reciprocating motion of the windshield 31.

[0039] Reference Figure 3 and Figure 4The first limiting member 5 includes a plurality of rotating plates 51 which are arranged side by side at the air suction port 211 and block the air suction port 211. Both ends of the rotating plates 51 are fixedly connected with rotating rods, one of which is located at one end of the side wall of the material storage slot and is coaxially fixed with an adjusting gear 52. A transmission rack 53 is provided on the same side of all the adjusting gears 52. The transmission rack 53 is meshed with all the adjusting gears 52 at the same time. A first gear 54 and a second gear 55 are also meshed on the transmission rack 53. The first gear 54 and the second gear 55 are meshed on the side away from each other with a driving rack 56 which is slidably connected to the material storage box 21. The end of the driving rack 56 away from the driving rack 53 is set to a hemispherical shape and penetrates into the air duct 212. The wind shield plate 31 can abut against the driving rack 56.

[0040] When the wind shield plate 31 abuts against the driving rack 56 near the end of the air suction port 211, the driving rack 56 is squeezed and slides into the side wall of the storage box 21, and drives the first gear 54 to rotate, and the first gear 54 drives the transmission rack 53 to move, and the transmission rack 53 simultaneously drives the adjustment gear 52 and the driving rack 56 near the end of the air outlet 213. At this time, the adjustment gear 52 rotates and drives the rotating plate 51 to rotate, the air suction port 211 is opened, and the driving rack 56 near the end of the air outlet 213 is moved on the second gear 52. 5 moves toward the air duct 212 and enters the air duct 212. Conversely, when the wind shield plate 31 abuts against the driving rack 56 at one end near the exhaust port 213, the driving rack 56 at one end near the exhaust port 213 is squeezed into the side wall of the storage box 21. At this time, the adjusting gear 52 drives the rotating plate 51 to rotate in the opposite direction and closes the air suction port 211. The first gear 54 drives the driving rack 56 at one end near the air suction port 211 to move and penetrate into the air duct 212, thereby realizing the air suction work of the air suction port 211.

The limiting block 62 is fixedly connected to the material storage box 21, and the exhaust plate 61 is configured as an elastic plate.

[0042] When the exhaust plate 61 is squeezed by air on the side close to the limit block 62, the exhaust plate 61 bends, so that the air drives the dust material into the exhaust port 213. When the exhaust port 213 is squeezed on the side away from the limit block 62, the exhaust plate 61 is restricted by the limit block 62 and is always in a state of blocking the exhaust port 213. At this time, the outside wind and the dust in the filter bag cannot enter the air duct 212.

[0043] Reference Figure 2 , Figure 3 and Figure 6The upper end of the inner wall of the material storage box 21 is wide and the lower end is narrow.

[0044] When the transmission rack 53 moves, it drives the ball screw 77 to move, and the ball screw 77 drives the driving plate 76 to rotate. The driving plate 76 drives the toggle rod 75 to move around the axis of the ball screw 77. The toggle rod 75 abuts against the inner wall of the rectangular frame 74 and drives the rectangular frame 74 to reciprocate. The rectangular frame 74 drives the moving rack 73 to reciprocate, and then drives the rotating ring gear 72 and the sleeve 7 to rotate. Therefore, the spiral blades 71 on the inner wall of the sleeve 7 can quickly clear the material inside the storage box 21 and speed up the material transmission.

The crushing block 9 rotates, and the smaller powder passes through the screening plate 8 through the sieve holes, and the larger lumps are crushed by the crushing teeth 93 on the crushing block 9, thereby reducing the possibility of powder agglomeration. At the same time, the crushing teeth 93 squeeze the protrusions 81 during the rotation process, causing the screening plate 8 to vibrate, thereby accelerating the passing speed of the powder between the screening plate 8 and the crushing block 9.
