Description

Technical Field

[0001] The utility model belongs to the technical field of gas-material separators, and in particular relates to a gas-material separator for a shredded stem low-speed airflow dryer with an inner wall cleaning device. Background Art

[0002] In cigarette production equipment, the low-speed airflow drying system of cut stems is mainly composed of a cut stem expansion device, a feed air lock, a cut stem drying device, an air-material separation device, a hot air dust removal device and a circulating dehumidification device. The air-material separation device adopts a drum-type air-material separator, which is composed of an air-material separator shell and a screen. The screen is coaxially sleeved inside the separator shell and performs air-material separation by rotation. When the air-material separator is working inside, steam and materials are always sprayed in one direction (at a) inside it, and the materials inside the air-material separator fall from the lower outlet, while steam is extracted from one end of the screen, thereby forming a whirlpool on the other side (at b) inside the shell of the air-material separator. The place where the steam is sprayed inside the shell is always subjected to the spray force, and the inner wall will not stick to the cut stems, while there is no spray force on the inner wall of the whirlpool, and because the moisture in the cut stems is very large, the cut stems are easily adhered to the inner wall of the whirlpool, which requires manual regular cleaning, thereby increasing the labor intensity. Therefore, it is necessary to propose improvements. Utility Model Content
