Abstract
The utility model discloses a disc gap control device for a disc heat disperser. The disc gap control device includes a PLC control unit, a PID controller, an electronic amplifier, a servo proportional valve and a displacement sensor. The PLC control unit communicates signals with the PID controller. The PID controller sends a signal to the electronic amplifier. The electronic amplifier then sends the signal to the servo proportional valve. The servo proportional valve controls the action of a hydraulic cylinder. The hydraulic cylinder controls the action of a disc of the disc heat disperser. The displacement sensor senses the action of the hydraulic cylinder and sends the signal to the PLC control unit and the PID controller. The disc gap control device for the disc heat disperser enables precise control of a disc gap.
Description
Technical field
The utility model relates to the disc gap control device of a kind of disc-type heat dispersing machine, particularly a kind of disc-type heat dispersing machine.
Background technology
Since the last century the nineties, because the waste paper quality is increasingly low, impurity increases increasingly, add novel ink, the continuous appearance of novel sicker (wherein many proportion is close to 1), make every effort to use the requirement of low-grade waste paper (as Mixed Office WasteMOW) production high-grade culture paper using day by day urgent, market waits in expectation and can solve above-mentioned new problem energy-efficient waste paper impurity dispersing apparatus appearance, can say that disc-type heat dispersing machine has become the key treatment facility of modernization Deinking line, in order to impel separating of residual ink and fiber, broken Jie's spot is to improve the efficiency of rear flotation.Bleaching makes the latter's application more go up first floor with the combination of disc type dispersion machine, carry out oxidation and reducing bleach in the disc type dispersion machine, greatly saved the expense of bleaching system, the high temperature (more than 90 ℃) of heat dispersion machine is high dense simultaneously, catalatic problem while thoroughly having solved hydrogen peroxide bleaching, through using, find: no matter be oxidation or reducing bleach, bleaching effect is all fine.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of disc gap control device of disc-type heat dispersing machine is provided.
A kind of disc gap control device of disc-type heat dispersing machine, include PLC control module, PID controller, electron-amplifier, servo proportion, reach displacement transducer, PLC control module and PID controller are the signal intercommunication, the PID controller sends signal to electron-amplifier, electron-amplifier sends signal to servo proportion again, servo relatively valve is controlled the action of hydraulic cylinder, hydraulic cylinder is controlled the Moving plate action of disc-type heat dispersing machine, the action of displacement transducer induction hydraulic cylinder, and signal is sent into to PLC control module and PID controller.
The hydraulic oil of the main-control hydraulic station of disc-type heat dispersing machine through regulating (flow and pressure) enters hydraulic cylinder through servo proportion, and hydraulic cylinder drives Moving plate and moves, and moves forward Moving plate and price fixing gap and reduces, and gap becomes large backward.Concrete moving parameter value is inputted by PLC (programmable logic controller (PLC)).To given signal of E-ME-K-PID controller electronic controller (voltage signal V1), be required gap by PLC.This signal drives spool displacement to after the E-ME-T-01H electron-amplifier amplifies the electronics proportional servo valve and then drives hydraulic cylinder (Moving plate) to move forward.The displacement transducer of device on Moving plate (hydraulic cylinder piston rod) monitored the displacement situation of Moving plate constantly, and the distance that will survey (variation of resistance value) is translated into voltage signal V2 through the PID controller and inputs to PLC and compare.Suppose that V1>V2 inputs the displacement value and be greater than actual movement value, PLC drives Moving plate to continue to move forward through PID and electron-amplifier to servo proportion the error signal (voltage signal V3) produced, and the distance that displacement transducer will survey (variation of resistance value) is translated into voltage signal V4 through the PID controller and inputs to PLC and carry out the inferior comparison of a new round.Through circulation (V when the gap precision value that reaches setting is 0.01mm repeatedly
n-V
n+1the a of)=± system no longer compares circulation (dead band S1 state).Spool position enters temporary transient lock-out state.Thereby reach to the accurate control in disc type dispersion machine disc gap.
In sum, the utility model following advantage compared to existing technology:
The disc gap control device of disc-type heat dispersing machine of the present utility model, can realize the accurate control to the disc gap, thereby improve the dispersibility of dispersion machine and disperse precision.
