Abstract

The invention relates to an energy-efficient threshing and pneumatic separating process and device. The energy-efficient threshing and pneumatic separating process is characterized in that a two-bin pneumatic separator is adopted for a first stage pneumatic separating unit; three-bin pneumatic separators are adopted for a second stage pneumatic separating unit, a third stage pneumatic separating unit and a fourth stage pneumatic separating unit; and the strips yield of the first stage pneumatic separating unit, the second stage pneumatic separating unit, the third stage pneumatic separating unit and the fourth stage pneumatic separating unit is respectively 45-64%, 15-30%, 10-15% and 5-15%. The strips yield is decreased gradually so that the device dimensions and capacities of the second stage pneumatic separating unit, the third stage pneumatic separating unit and the fourth stage pneumatic separating unit are decreased gradually, and the physical dimension of the fourth stage pneumatic separating unit is 1 / 2 that of the first stage pneumatic separating unit. The purpose of separating qualified tobacco flakes and tobacco stalks is achieved through the technological process, adjustment of the pressure balancing surface position in separation bins of the two-bin pneumatic separator and each three-bin pneumatic separator of the first to fourth stage pneumatic separating units and speed adjustment of a conveying mesh belt.

Description

technical field

[0001] The invention relates to a high-efficiency and energy-saving threshing and air separation process, in particular to a new technology for wind-force sorting and transportation of tobacco sheets and tobacco stems, and a new wind pressure type air separation equipment. The invention belongs to the technical field of threshing and redrying technology and equipment in the tobacco processing industry. Background technique

[0002] At present, in the domestic tobacco processing industry, the threshing and air separation process of the threshing and redrying production line has the technological characteristics of graded leaf threshing and multiple air separation and discharge. Separation, the separated tobacco flakes and tobacco stem mixture are transported to the air separator for air sorting of the tobacco flakes.

[0003] The domestic threshing air separation production process is: after the mixture of tobacco flakes and tobacco stems after the first-leve...
