Technical Field

[0001] The utility model relates to the technical field of tobacco leaf processing, in particular to an air bearing sealing component of a leaf threshing and redrying air separator. Background Art

[0002] Tobacco leaves are one of the raw materials for cigarettes. When processing tobacco leaves, a threshing and redrying air separator is required. When the threshing and redrying air separator is working, the bearing seat is completely in a negative pressure wind working environment. Under the action of the negative pressure wind, the grease inside the bearing is slowly drawn away by the negative pressure wind. Since the wind system of the entire air separator adopts a mixed circulation type, the drawn grease directly contacts the tobacco leaves.

[0003] After searching, it was found that when using common tobacco leaf threshing and redrying air separators, there is a lot of lubricating oil on the bearings. During the processing, the lubricating oil on the bearings may leak from the bearing box and enter the processing area to contaminate the tobacco leaves. Therefore, it is necessary to use a sealing component to seal the bearing box.

[0004] In summary, there is an urgent need for a component that can seal the air lock bearing of the leaf-threshing and re-drying air separator. Utility Model Content
