Abstract

The invention provides a uniform-feeding, atomizing, humidifying and water control system. A water cascade control model comprising an outlet water control loop and a feed water flow control loop is built, the outlet water control loop is a main ring, and outlet water of a screw feeder is a control object of the main ring; the feed water flow control loop is an auxiliary ring, and feed water flow is a control object of the auxiliary ring. The water cascade control model utilizes the outlet water of the screw feeder as a control objective. The outlet water control loop utilizes difference between the final raw material outlet water measuring value and the set target value as input, output value of the water outlet control loop is converted as the set value of the feed water flow control loop, and the feed water flow control loop utilizes the difference between the set value and the feed water flow measuring value as input, and control value is outputted to a flow regulating valve via operation. Water added into the raw materials is controlled by a closed loop, and outlet water content of the screw feeder is automatically and stably controlled.

Description

technical field [0001] The invention relates to uniform feed, dust removal, water addition and moisture automatic control of tobacco sheet raw materials, in particular to a uniform feed spray humidification moisture control system. Background technique [0002] The core equipment for the pretreatment of tobacco sheet raw materials is the spray humidification screw conveyor and uniform feeding device. Such as figure 1 As shown, the uniform feeding device is composed of a feeding fan 1, a storage tank and a feeding fan 4, and the screw conveyor is composed of a motor, a screw conveying rod 5 and a spraying device 6. There are ten nozzles arranged on the left and right sides of the screw conveyor, five nozzles are connected to the water main pipeline, and five joints are connected to the compressed air main pipeline. A flow controller (comprising a flow meter) 22 and a flow regulating valve 21 are installed on the spray main pipe, and a pressure transmitter for detecting wate...
