A high-efficiency energy-saving leaf threshing air separation process and equipment

Abstract

The invention relates to a high-efficiency and energy-saving air separation process and equipment for leaf threshing, and belongs to the technical field of air separation process and equipment for tobacco materials. The present invention is provided with four air-pressure type double-chamber air sub-machines between the first-stage leaf-threshing unit and the second-stage leaf-threshing unit, and the air-pressure type double-chamber air sub-machine is connected in parallel; There are two air-pressure type three-storey air sub-machines between the three-stage leaf threshing machines, and the air-pressure three-storey air sub-machines are parallel-connected; there is a wind pressure type between the third-stage leaf-threshing machine and the fourth-stage leaf-threshing machine. The three-storey air sub-machine is connected in series; the traditional wind pipeline is changed to a conveyor belt and a vibrating trough to transport materials, which is not easy to block materials, reduces the loss of material temperature and moisture, and reduces the dryness of materials. The transmission power is small and greatly improved. The energy consumption and noise are reduced, and the rate of large and medium sheets of discharged smoke sheet is improved.

Description

technical field [0001] The invention relates to a high-efficiency energy-saving leaf threshing air separation process and equipment, in particular to a novel process and equipment for air separation of tobacco sheets, tobacco stems, dust and fines, and belongs to the technical field of material air separation process and equipment. Background technique [0002] At present, in the production and processing process of domestic threshing and redrying, the tobacco leaves are separated from the stems and leaves by the threshing unit. The separated leaves and stalks are transported to the air separation bin of the air separator for air separation. The tobacco leaves with unseparated stems are transported to the next level of leaf thresher for repeated thresher, and the pure leaves and tobacco stems are sorted out through repeated leaf thrashing and air separation. The traditional material conveying device is composed of a feeder, a conveying fan and a pipeline, and its function i...

Problems solved by technology

[0003] The effective blades selected based on the traditional CN102626257A and CN2791087Y air separators are sent by air and then separated by a rotary feeder, which cannot meet the requirements of the new technology.
