For achieving the above object, the utility model is by the following technical solutions:
A kind of leaf water control device, comprise priming apparatus and control device, priming apparatus comprises steam pipework, compressed air line, water lines, Pneumatic diaphragm valve and dual-medium nozzle, and control device comprises PLC, flowmeter, electropneumatic positioner, Moisture Meter, belted electronic balance; Compressed air line is connected with electropneumatic positioner and is used for providing source of the gas, electropneumatic positioner is connected for controlling air bladder valve opening with Pneumatic diaphragm valve, the Pneumatic diaphragm valve port of export is connected with flowmeter arrival end by pipeline, and flowmeter outlet end is connected with dual-medium nozzle by pipeline; Steam pipework in priming apparatus divides two-way, one tunnel is connected with dual-medium nozzle and is used for atomized water, water is ejected on blade uniformly, another road is connected with Pneumatic diaphragm valve, control air bladder valve opening by electropneumatic positioner, pass into charging aperture after Pneumatic diaphragm valve is connected with pipeline for adjusting vane moisture; Moisture Meter, belted electronic balance are all connected with PLC, and moisture signal and supplied materials flow signal are connected with the analog input module of PLC; Flowmeter, electropneumatic positioner are connected with described PLC.
The utility model is compared with existing background technology, and tool has the following advantages:
1, the utility model can carry out Precise control to whole production process, and the moisture control procedure controllability that blade is got damp again is good, automaticity is high, improves stability and the uniformity of exit vane moisture, ensure that the effect that blade gets damp again.
2, the utility model moisture content control device structure regulating parameter is various, and controllability is good, can adapt to the technological requirement of different material, kinds of cigarettes product.
3, the utility model is reasonable in design, structure is simple, and efficiently solve due to blade contained humidity and Leaf water absorption performance difference, the fluctuation of blade loosening steam conditioner exit vane moisture is larger than technological requirement problem.Improve the automatic control level of blade loosening steam conditioner discharge end leaf water, guarantee the uniformity of leaf water, stability.
