When the cleaning button is turned off, there is a falling edge at the start input terminal (S) of the timer. The off delay timer T120 will start the timing function, and the output terminal Q of the timer still outputs a high level. When the set time reaches 3 minutes, the output of the output terminal Q changes from high level 1 to low level 0, the PLC digital output template Q11.6 outputs low level, and the cleaning water solenoid valve is turned off. Thus, the timing control function of the washing water is realized. When the manual stop button is pressed, the delayed disconnect timer T120 is reset, no matter whether the cycle is completed or not, Q11.6 is no longer output, and the solenoid valve for dehumidification and cleaning water is disconnected when power is off, and the water is stopped.
Through continuous operation for a period of time, it was found that although the stem-sweetening drum moisture-discharging fan added a cleaning function, it was found in actual use that the function could not be achieved according to the goals envisaged in the previous period, mainly because the cleaning water could not be smoothly discharged from the drainage pipe , Can not effectively remove the dirt adhering to the inside of the drain pipe. The main reason for this phenomenon is that the speed of the moisture discharge fan is relatively high, generally about 2850rpm, such a high speed forms a relatively large negative pressure in the inlet of the fan and the drainage pipe, the negative pressure is enough to make the water entering the drainage pipe Suck back into the fan.
Most of the cleaning water flows out through the inlet of the fan, and a small part flows out through the gaps in the flange of the outlet of the fan. Aiming at the phenomenon that the cleaning water cannot be smoothly discharged from the drainage pipe, the following countermeasures were formulated based on the above reasons: reduce the fan speed and reduce the negative pressure of the drainage pipe. Because the damp exhaust fan is directly driven by the feeder, and does not use a soft starter or frequency conversion information technology and information automatic controller, the method of reducing the wind speed of the fan can only be used to start and stop intermittently, and at the same time, according to the low resistance of the fan at low speed, the inertia The big feature is that the start-stop time can be set to be relatively small, and the specific data can be obtained through experiments.
