Description
Изобретение относитс к способам определени влажности бумажного полотна в процессе его изготовлени на бумаго- или картоноделательной машине и может найти применение в целлюлозно-бумажной промышленности .The invention relates to methods for determining the moisture content of a paper web during its manufacture on a paper or board machine and may find application in the pulp and paper industry.
Известны способы измерени влажности бумажного полотна путем замера величин, функционально св занных с влажностью материала .Methods are known for measuring the moisture of a paper web by measuring values functionally related to the moisture of a material.
Цель - повышение надежности измерени .The goal is to increase measurement reliability.
Предложено в качестве функционального показател влажности полотна принимать изменение ширины полотна на выходе из сушильной части бумагоделательной машины.It is proposed to accept the change in the width of the web as it leaves the drying part of the paper machine as a functional indicator of the moisture content of the web.
На чертеже представлена схема, иллюстрируюш ,а предлагаемый способ.The drawing shows a diagram, illustrate, and the proposed method.
По обе стороны машины, с лицевой и с приводной, на выходе из сушильной части устанавливают два датчика перемещени / и 2, контактирующих с бумажным полотном 3. Сигналы, поступающие от датчиков, подают на суммирующее устройство 4 и далее на измерительный прибор 5 и регул тор 6, управл ющий подачей пара в сушильную группу 7.On both sides of the machine, from the front and from the drive, at the outlet of the drying part, two displacement sensors / and 2 are installed, which are in contact with the paper web 3. Signals from the sensors are fed to summing device 4 and further to measuring device 5 and controller 6 controlling the steam supply to the drying group 7.
При изменении влажности полотна мен етс его ширина и в системе возникают импульсы , соответствующие знаку и величине изменени .When the moisture of the web changes, its width changes and impulses occur in the system, corresponding to the sign and magnitude of the change.
При этом измен ютс показани измерительного прибора 5, по которому суд т о влажности бумаж1юго полотна. Эти же импульсы управл ют подачей пара в сушильную группу посредством регул тора.In this case, the readings of the measuring device 5, according to which the humidity of the paper web is judged, change. These same pulses control the steam supply to the drying group by means of a regulator.
Предмет изобретени Subject invention
Способ измерени влажности бумажного полотна путем замера величин, функционально св занных с влажностью материала, отличающийс тем, что, с целью повышени надежности измерени , в качестве функционального показател влажности полотна принимают изменение ширины полотна на выходе из сушильной части бумагоделательной машииы .A method of measuring the moisture of a paper web by measuring values functionally related to the moisture of a material, characterized in that, in order to increase the reliability of the measurement, a change in the width of the web at the outlet of the drying part of the paper machine is taken as a functional indicator of the moisture of the web.
