Technical Field

[0001] The utility model relates to the technical field of synthetic fiber production, in particular to a component for solving the problem of material blockage in a slice conveying process. Background Art

[0002] In the production process of nylon 66 fiber, compressed air is used to transport the raw material slices to the replacement silo above the drying tower (to replace N2). A large amount of dust is generated during the transportation of the slices, and the dust will be discharged from the replacement silo along with the compressed air. There is an air outlet pipe above the silo. To prevent the slices from overflowing, a metal filter is installed at the air outlet pipe. The dust and small particles in the slices will clog the air outlet pipe filter during the discharge process, causing the compressed air to be unable to be discharged, affecting the transportation of the slices. The filter needs to be manually cleaned once every 4 hours, which is manpower-consuming. In addition, the replacement silo is on a high platform, which poses a safety hazard. Utility Model Content

Since there is a gap between the filter cylinder 4 and the limit ring 2, the swing arm 13 pushes the force block 41 to move the filter cylinder 4. At the same time, due to the action of the tension spring 62, the filter cylinder 4 is reset after moving, thereby causing the filter cylinder 4 to vibrate back and forth, and the dust adsorbed on the filter cylinder 4 is vibrated and falls, preventing dust from accumulating on the filter cylinder 4. When the fan 80 is exhausting air, the system The wind speed is formed in the system, and then the fan blades 12 rotate after the wind passes through the fan blades 12, without the need to drive them to rotate through an external device.

[0025] When using this utility model:

[0026] First, the fan 80 starts to draw air, which creates a wind speed in the system, and then the fan blades 12 rotate after the wind passes through them.

[0027] Then, due to the negative pressure in the system, the material enters the silo 20 through the fixing ring 1. The air entering the silo 20 enters the negative pressure tank 40 through the exhaust pipe 30, and the dust in the air is filtered out by the anti-blocking component 50. At this time, some dust is adsorbed on the filter cylinder 4, and some dust falls into the regulating component 6. The filtered air is discharged through the connecting pipe 70 and the outlet pipe 90.

[0028] Then, when the anti-blocking component 50 is filtering, the fan blade 12 drives the swing arm 13 and the rotating rod 51 to rotate, and the swing arm 13 rotates to hit the force block 41. Since there is a gap between the filter screen drum 4 and the limiting ring 2, the swing arm 13 pushes the force block 41 to move the filter screen drum 4. At the same time, due to the action of the tension spring 62, the filter screen drum 4 is reset after moving, thereby causing the filter screen drum 4 to vibrate back and forth, and the dust adsorbed on the filter screen drum 4 is vibrated and falls, preventing dust from accumulating on the filter screen drum 4. The rotation of the rotating rod 51 drives the scraper 52 and the brush roller 54 to rotate. The scraper 52 scrapes off the dust adsorbed on the surface of the filter screen drum 4, and the brush roller 54 pushes out the dust in the filter holes of the filter screen drum 4 and scrapes the dust off through the scraper 52.

[0029] Finally, the scraped dust falls into the dust collection bucket 60 for collection, and the dust collection bucket 60 only needs to be cleaned regularly.
