Air volume control device, system and method of cut tobacco winnowing machine

Abstract

The invention discloses an air volume control device, system and method of a tobacco winnowing machine. The device comprises a winnowing box body, a first winnowing machine and a second winnowing machine. A feeding port is formed in the top of the winnowing box body, the first winnowing machine is arranged on one side of the winnowing box body, a discharging port opposite to the first winnowing machine is formed in the other side of the winnowing box body, and the second winnowing machine is arranged at the bottom of the winnowing box body; the first winnowing machine conveys air in the horizontal direction towards the discharging port, the second winnowing machine conveys air in the vertical direction towards the feeding port, and therefore floating separation and flotation are conducted on cut tobacco through vertical and horizontal two-way air inlet. According to the tobacco shred winnowing device, the tobacco shred is subjected to floating separation and flotation through vertical and horizontal two-way air inlet of the box body, objects with large density such as wet masses and slivers fall down through the winnowing box body, objects with low density such as normal tobacco shred are sent out of the box body through the discharging pipe, and therefore the flexible processing purpose of tobacco shred winnowing is achieved.

Description

technical field [0001] The invention relates to the technical field of shredded tobacco air separation, and more particularly, to an air volume control device, system and method of a shredded tobacco air separation machine. Background technique [0002] The cut tobacco air separator is generally used to remove the sundries and unqualified products in the cut tobacco on the wire making line. After placing it in the cut tobacco drying process, it can be used as a blending and homogenizing equipment for the cut tobacco. It not only makes the cut tobacco blend uniformly, but also The moisture of the blended cut tobacco is more uniform, thereby improving the quality of the silk making process. [0003] However, the distribution of air pressure and air volume of the wire mesh ventilation is obviously uneven. The farther away from the air extraction port, the smaller the air pressure and air volume. In the shredded tobacco air separator, because the feeding belt is far away from th...

[0003] However, the wind pressure and air volume distribution of wire mesh ventilation is obviously uneven. The farther away from the air outlet, the smaller the wind pressure and air volume. The exhaust fan provides a large air volume to raise the shredded tobacco on the feeding belt, which consumes a lot of power. Moreover, in the air duct of the s
