Abstract
The invention discloses a constant pressure control system of a high pressure induced-draft fan. The constant pressure control system comprises a man-machine operation interface, a signal collection unit, a signal conversion unit, a signal processing unit and a frequency converter. The man-machine operation interface comprises an input keyboard and a displayer, wherein the input keyboard is used for inputting induced-draft pressure parameters. The signal collection unit is installed at an exhaust inlet of the high pressure induced-draft fan and used for collecting pressure signals of the high pressure induced-draft fan. The signal conversion unit converts the pressure signals into electric signals and transmits the electric signals to the signal processing unit. The signal processing unit conducts comparison between the electric signals and the induced-draft pressure parameters input into the man-machine operation interface to obtain a control signal, and then outputs the control signal to the frequency converter. The frequency converter regulates the rotating speed of a motor of the high pressure induced-draft fan according to the control signal. The constant pressure control system achieves the purposes that induced-draft pressure can be regulated according to corrugated boards with different gram weights, heat loss is reduced, and electric energy loss is lowered.
Description
Technical field
The present invention relates to corrugated board manufacturing technology field, particularly a kind of high pressure induced-draught fan control system of invariable pressure.
Background technology
Outer-cover type vacuum suction by suspended hood, lead paper copper sheet, aspiration channel, air door, high pressure induced-draught fan and silencer and form.On the lower corrugated roller roll surface of outer-cover type vacuum suction, be evenly distributed with air draught groove, high pressure induced-draught fan is through the strong exhausting of aspiration channel, make to form negative pressure between suspended hood inner chamber and lower corrugated roller, by the air draught groove on lower corrugated roller, the corrugated paper after moulding is close on lower corrugated roller, complete exactly gluing compound working procedure, by being arranged on suspended hood and stretching into, in the air draught groove of lower corrugated roller, lead paper copper sheet again, two layers of corrugated board that composite drying is good are guided out from lower corrugated roller, air door can regulate control suction air volume during this time, silencer reduces the noise of air draught air-flow.Change the Corrugator roller of different stupefied types, can produce two layers of corrugated board of various stupefied types.Outer-cover type vacuum suction, owing to adopting negative pressure of vacuum principle to carry out the corrugated paper after positioning molding, has been eliminated and has been led pawl formula structure because of the location wild effect that mechanical wear causes, and is enough to adapt to run up.Especially minitype corrugation cardboard, corrugated paper intensity after moulding is low, yielding, should not locate, and the whole world only adopts the mode of vacuum suction or air cushion malleation to adapt to run up at present.
Due to the strong exhausting of high pressure induced-draught fan, height grammes per square metre constantly converts, and air quantity regulates and cannot adjust in time, often in process of production air quantity is adjusted to maximum, cause corrugated paper to cave in wind groove, cause corrugated board physical property to reduce, cause heat energy excessively lost, electric power significant wastage simultaneously.
