Technical Field

[0001] This application relates to the technical field of powder selection devices, and more particularly, to a cyclone air regulation structure. Background Art

[0002] A powder selection device, also known as a powder separator or classifier, is a device used to separate ground materials according to particle size in the grinding process. It is mainly used for the classification and quality control of powder materials in industries such as cement, mining, chemical engineering, ceramics, and metallurgy. The working principle of the powder separator is to use the combined action of air flow and mechanical devices to screen the powder materials to obtain products with the required particle size distribution.

[0003] Since the powder selection process requires the adjustment of air flow for better powder selection, the adjustment of the cyclone air is particularly important. The existing cyclone air structure, due to defects in the structure setting, can only adjust the air volume, but cannot cooperate with the angle adjustment, resulting in the inability to meet the powder selection adjustment requirements.

The air duct body 21 is connected to the air inlet pipe 1 through the flexible positioning pipe 3, and the angle can be flexibly adjusted manually. The air volume is adjusted in cooperation with the adjusting air damper 22 to realize flexible adjustment of the powder selection air volume and angle.

[0030] Specifically, a plurality of adjusting air valve structures 2 are arranged on the periphery of the air inlet pipe 1 to form a swirling air flow. The air flow rises along the air inlet pipe 1 to play a role in sorting materials. Based on the need for material powder selection, the angles and air volumes of the adjusting air valve structures 2 can be flexibly adjusted, so as to achieve a better powder selection effect.

[0037] Specifically, the flange member 24 is set as a blind flange member 24.

[0038] In this embodiment, by setting the blind flange member 24, on the one hand, it is convenient to connect with an external air blowing structure, and on the other hand, the air flow rate entering the air duct body 21 can be adjusted through the blind plate in cooperation with the adjusting air damper 22 to achieve a better powder selection effect.
