Air separator and separation method for separating tobacco leaves, tobacco stalks and leaves with stalks

Abstract

The invention discloses an air separator and a separation method for separating tobacco leaves, tobacco stalks and leaves with stalks. The air separator includes an air separating bin (10) arranged obliquely, wherein an upstream segment, a midstream segment and a downstream segment are arranged on the air separating bin (10), wherein the cross sectional area of the midstream segment is largest. Afeed air pipe (2) and a main air inlet pipe (4) are arranged on the upstream segment of the air separating bin (10), and a feed inlet (1) is formed in the feed air pipe (2). A feed air pipe adjustingdevice (3) is arranged at the discharge outlet of the feed air pipe (2), and a first downward outlet (6) is formed in the upstream segment of the air separating bin (10). A second downward outlet (7)is formed in the midstream segment, a third outlet (8) is formed in the midstream segment, and a negative pressure fan is arranged on the third outlet (8). The air separator and the separation methodfor the separating tobacco leaves, the tobacco stalks and the leaves with the stalks adopt an air belt material feeding mode to feed materials, the air belt material can enable the materials in unit volume to distribute more dispersion, and the air separating efficiency is improved, compared with a conventional material throwing roller and a high-speed belt feeding mode.

Description

technical field [0001] The invention belongs to the field of cigarette processing equipment, and in particular relates to an air separator and a separating method for separating tobacco leaves, tobacco stems and blades with stems. Background technique [0002] The principle of air separation is widely used in tobacco processing, including different forms of use in leaf threshing and redrying, silk making, and rolling processes. Leaf threshing air separation is the core process of leaf threshing and redrying. Baked product quality and various economic indicators. Based on the principle of material suspension, most traditional air separation equipment can only separate light and heavy materials, and the air separation efficiency of a single equipment is low, so it is necessary to install multi-stage air separation equipment (generally 11 to 18 levels) on the production line ), not only occupy a large space, but also lead to repeated processing of materials and serious crushin...
