Changsha Roots Blower Typical Use (VIII)
- Printer feed
The compressed air discharged from the blower is used to loosen the sheets of paper on the surface of the stack. The delivery nozzle picks up the top sheet and swings it forward, separating the paper from the stack and feeding it between the paper roller and the platen wheel. Under the friction between the feed roller and the platen, the paper is fed to the impression cylinder for printing.
- The compressed air provided by the blower is used to form a “knife” shaped airflow at the air knife nozzle and blow at a certain angle towards the paper web to even out the coating on the paper surface and scrape off the excess material. The coating molecules in the diffused gas can be separated and recovered with an aerosol separator. It is usually used for the coating of high-grade printing paper and plastic film.
- transfer grain to a warehouse
Grain coming down from the storage bin is forced into the conveying pipeline through a rotary valve. Compressed air supplied by a blower can be used to transport the grain to other silos, where it is separated from the air by a separator when it reaches the designated silo. When it is necessary to unload grain to several warehouses, a reversing valve can be used to control the flow of logistics.
- Bulk carrier suction and discharge
When unloading the grain from the grain ship, the suction force formed by the vacuum pump can be utilized to make the grain enter the conveying pipe from the suction nozzle along with the air to the separator for landing and unloading in the dock granary or on the belt conveyor. After separating the dusty air from the grains, it is purified by the dust collector and discharged by the vacuum pump. Bulk cement ship suction unloading is the same situation.
