Abstract
The utility model discloses an energy-saving control device for a drier, comprising a controller, and a water ratio sensor, a pressure transmitter and an electric valve which are respectively connected with the controller. Due to adoption of the technical proposal, the utility model solves the technical problems in the prior art of low drying precision, low drying efficiency, energy waste, high cost and so on of textile fabric which is dried by a manually operated drier and provides the energy-saving control device for the drier with capabilities of improving the drying precision of the textile fabric and the drying efficiency, saving energy and reducing the cost.
Description
Technical field
The utility model relates to a kind of control device that is used to dry the drying machine of fabric, particularly relates to a kind of energy-saving control device of drying machine.
Background technology
In dyeing, utilizing drying machine that fabric is dried processing is one important operation, normally adopt a kind of vertical drying machine that two columns are arranged, on the steam pipe that feeds drying machine, mechanical control valve is installed, be humidity traditionally by the artificial oven dry of impression by rule of thumb back cloth, manual adjustments valve again, with the steam in the control column, thus the drying capacity of indirect adjusting drying machine.
So there are several shortcomings in operation traditionally, the one, owing to be manually-operated, so accuracy is not high, efficient is also very low, and the fabric of producing is often dried excessively or not oven dry as yet, and the fabric quality of oven dry descends to some extent, has caused economic loss to enterprise; The 2nd, waste energy easily, increased the oven dry cost.
Summary of the invention
The utility model has mainly solved available technology adopting manually-operated drying machine, and to dry by the fire the fabric drying accuracy that low, drying efficiency is low, waste energy, cost high-technology problem, a kind of fabric drying degree of accuracy that improves is provided, can improve drying efficiency, energy savings, the energy-saving control device of the drying machine that reduces cost.
The technical solution of the utility model is achieved in that a kind of energy-saving control device of drying machine, it is characterized in that it includes controller, respectively the moisture sensor that is connected with controller, pressure transmitter and electrically operated valve.
As preferably, described controller is PLC.
As preferably, described controller also is connected with operating unit.
As preferably, described operating unit is a touch-screen.
Compare with prior art, the utlity model has following advantage: do not need to rely on traditional artificial experience, but the aperture of valve on the water cut value control steam pipe that the moisture content of precise real-time detection fabric and basis set, improved the oven dry degree of accuracy, thereby also saved the energy, reduce unnecessary waste, reduced the oven dry cost, improved drying efficiency.
Description of drawings
Fig. 1 is a block diagram of the present utility model;
Fig. 2 is a control system block diagram of the present utility model.
The specific embodiment
The specific embodiment of the present utility model is as follows: as shown in Figure 1, energy-saving control device according to a kind of drying machine of the present invention, it comprises controller, the moisture content of fabric sensor that links to each other with controller respectively, two adjustment type electrically operated valves and two pressure transmitters.This device is suitable for having the drying machine of two groups of drying cylinders, and common controller adopts PLC, and setting pressure transmitter and modulability electrically operated valve on the jet chimney of two groups of drying cylinders respectively are installed in the test point of moisture content of fabric sensor in the exit of fabric.Described controller also is connected with operating unit, and operating unit is a touch-screen, can set a needed moisture content of fabric setting value by operating unit, and this device adopts two closed loop control algorithms, and interior ring is a pressure rings, and outer shroud is the moisture content of fabric ring.Owing to need many columns of control drying machine, so this device is provided with two closed loops of respective numbers according to the logarithm of column dryer.
During work, this control device compares with the moisture content setting value and draws the moisture content difference by the moisture content of fabric in moisture sensor timing sampling exit.The pipeline pressure set-point of ring in controller draws according to this difference utilization pid algorithm.In the PID operation program of ring compare according to the drying cylinder actual pressure value that given force value and pressure transmitter transmit, calculate the aperture of steam valve, drive the adjustment type motor-driven valve to control the flow of steam by executing agency again.Increase the drying capacity that steam flow will increase dryer, reduce the moisture content of fabric.Otherwise the minimizing steam flow will reduce the drying capacity of dryer, and the moisture content of rising fabric had both guaranteed so then that moisture content of fabric satisfied technological requirement, reduces the steam consumption in the oven dry production process again.
Claims (4)
1, a kind of energy-saving control device of drying machine is characterized in that it includes controller, respectively the moisture sensor that is connected with controller, pressure transmitter and electrically operated valve.
