Abstract
Drying roller temperature automatic control device, including temperature sensor, PID controller and proportion air -vent valve, temperature sensor establishes the import department at the roller, and temperature sensor meets with the PID controller, and the PID controller meets with the proportion air -vent valve, the proportion air -vent valve establish the department at steam outlet. The utility model discloses a drying roller temperature automatic control device adopts closed -loop control, and temperature sensor can the real -time detection roller steam temperature of import department to the PID controller is given in the transmission, and the PID controller compares with to set the temperature after receiving temperature data, through operation, output current signal, and the aperture of controlling ratio air -vent valve, thus the purpose of control roller temperature is reached through control steam flow.
Description
Technical field
This utility model belongs to automatic temperature control, specifically a kind of dryer roll automatic temperature control.
Background technology
The speed of production of existing fiber steel wire calendaring linkage line reaches 6-60 m/min, and wherein dryer roll preheating device is positioned at pressure
Before prolonging main frame, it is used for being dried cord, reduces the moisture of remaining in cord, required to meet when cord enters calendering main frame
Humidity condition.Dryer roll preheating apparatus include 10 a diameter of 600 millimeters, the roller of a length of 1700 millimeters, spy
Different swivel joint is equipped with flexible pipe, liquid distribution shunt valve, on-off valve, thermometer and manual pressure regulating valve.10 kg of vapor are passed through
Manual pressure regulating valve enters each roller through special swivel joint, and in roller, condensed water is then flowed out by coaxial special swivel joint.
The temperature of 10 kg of vapor is 179.4 DEG C;According to technological requirement, temperature requirement 110 ± 10 DEG C when producing polyester cord, produce
Temperature requirement 80 ± 10 DEG C during nylon cord fabrics;Valve must be regulated to reach technological requirement by Non-follow control when producing every time.Work as production
During velocity variations, use manual pressure regulating valve can not accomplish in time, control accurately, but also waste of manpower.
Utility model content
In order to solve the problem that prior art exists, this utility model provides a kind of dryer roll automatic temperature control, this dress
Put and temperature required and bound scope can be set according to technological requirement, automatically control proportion adjustment valve opening so that actual roller
Temperature is rapidly achieved technological requirement.
This utility model adopts the following technical scheme that dryer roll automatic temperature control, including temperature sensor, PID control
Device processed and proportional dump valve, temperature sensor is located at the import department of roller, and temperature sensor connects with PID controller, PID
Controller connects with proportional dump valve, and described proportional dump valve is located at steam outlet.
When producing beginning, dryer roll automatic temperature control can arrange required temperature and bound according to technological requirement
Scope, automatic control and adjustment valve opening makes actual roller temperature be rapidly achieved technological requirement.In production process, especially produce speed
During degree change, dryer roll automatic temperature control can adjust roller temperature in real time, accurately, be controlled by roller temperature
In the range of technological requirement, on the one hand save manpower, on the other hand can reduce the generation of extrudate defective products (when roller temperature
When spending high, polyester/nylon fiber edge can be shunk, and causes the extrudate material width of production not meet.When roller temperature mistake
Time low, polyester/nylon fibre moisture is too big, causes the extrudate material of production to cover glue effect bad, the tyre performance produced
Reduce, or even be waste product).
Dryer roll automatic temperature control of the present utility model uses closed loop control, and temperature sensor can detect roller in real time
Import department's vapor (steam) temperature, and it is transferred to PID controller, after PID controller receives temperature data, compare with the temperature set,
By computing, output current signal, control the aperture of proportional dump valve, thus reach to control roller by controlling steam flow
The purpose of temperature.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model dryer roll automatic temperature control.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described specifically:
Dryer roll automatic temperature control, as it is shown in figure 1, include temperature sensor, PID controller and proportional dump valve,
Temperature sensor uses platinum resistance thermometer sensor, PT100, model WZP-231, and detection temperature range is 0~200 DEG C, temperature sensor
Being located at the import department of roller, inserting is 50mm deeply, is used for detecting roller inlet steam temperature, and temperature sensor controls with PID
Device connects, and PID controller connects with proportional dump valve, and proportional dump valve is located at steam outlet.The model of PID controller
For DDCB-32DRNN1, the resistance signal of PT100 is converted to digital quantity temperature, compared with design temperature, carries out
PID arithmetic, exports 4~20mA current signals, drives proportional dump valve work, and wherein 4~20mA current signals are corresponding
0~100% aperture.
Claims (2)
1. dryer roll automatic temperature control, it is characterised in that: include temperature sensor, PID controller and proportional dump valve,
Temperature sensor is located at the import department of roller, and temperature sensor connects with PID controller, PID controller and proportional dump valve
Connecting, described proportional dump valve is located at steam outlet.
Dryer roll automatic temperature control the most according to claim 1, it is characterised in that: described PID controller is defeated
The current signal scope gone out is 4~20mA, and the aperture corresponding to proportional dump valve is 0~100%.
