[0025] Description of the working method of this utility model:

[0026] Before the production of powder materials, the ton bag 15 is hung in the cube frame to form a certain storage space in the ton bag 15. The pipeline for conveying the powder materials extends into the ton bag 15 through one open end of the ton bag 15 and is suspended in the air, while the other open end of the ton bag 15 extends into the double-tube structure 16 of the device and is installed and fixed by the clamping structure on the inner tube 1. The clamping structure clamps the ton bag 15 around the inner tube 1 to form an enclosure, and the double-tube structure 16 and the pipeline for conveying the powder materials can be sealed with a clip or a zipper. When the production of powder material begins, the vacuum cleaner 12 is turned on in advance so that the gas in the ton bag 15 forms an airflow leading to the vacuum cleaner 12. When the powder material is continuously transported to the ton bag 15, a large amount of dust will be raised. At this time, the dust-entrained particles enter from between the inner tube 1 and the outer tube 2 of the device. Under the filtration of the filter 10, larger impurities are blocked. After the particulate dust passes through the filter 10, it moves upward in the inner tube 1 and enters the vacuum cleaner 12. Finally, under the action of the filter 13 of the vacuum cleaner 12 and the dust bag 14, the particulate matter and dust are separated and collected, and clean air is discharged.
