Abstract

The invention discloses a self-adaptive control system for performing air conveying on fragile materials. The system comprises a PLC intelligent controller, an intelligent power saver and a conveyingdevice which are connected electrically and mutually; the conveying device comprises a centrifugal fan electrically connected with the intelligent power saver; the output end of the centrifugal ventilator is connected with a first roll-packing machine through a conveying pipeline; the conveying pipeline comprises a total pipeline connected with the centrifugal ventilator as well as a first branched pipeline connected with the first roll-packing machine; the total pipeline is communicated with the first branched pipeline; a first pneumatic regulating butterfly valve, a first pneumatic regulating valve, a pressure transmitter and a first flowmeter are arranged sequentially from one end, near the first roll-packing machine, of the first branched pipeline to one end, near the total pipeline ofthe first branched pipeline; a butterfly valve is arranged on the total pipeline; the butterfly valve is positioned between the centrifugal ventilator and the first branched pipeline; the first branched pipe and the first roll-packing machine are connected through a first pneumatic shut-off valve; the first roll-packing machine is connected with a wire feeding machine through a wire feeding pipeline; and a second flowmeter is arranged on the first wire feeding pipeline.

Description

technical field [0001] The invention relates to the technical field of wind power conveying, in particular to an adaptive control system for wind power conveying fragile materials. Background technique [0002] The cut tobacco supply method used by large cigarette factories adopts the most popular pipeline negative pressure wind conveying at present; negative pressure wind conveying is favored by domestic and foreign counterparts for its advantages of low investment, high reliability, low operation and maintenance costs, clean and environmental protection, etc. [0003] Under the condition of the pipe structure of shredded tobacco, the temperature, humidity and water content of shredded tobacco, the shredded rate and water loss degree of shredded tobacco mainly depend on the speed of wind conveying, the stability of conveying speed, and the relationship between shredded tobacco and conveying at the beginning of conveying each time. Tobacco negative pressure wind conveying is...
