Working Principle Of Purifying Hot Air Circulation Oven

The working principle of the purifying hot air circulation oven: When the temperature reaches the set value, the temperature controller outputs the PID control signal PLC, and the PLC outputs the control signal to the time relay KT to start the heat preservation time. At the same time, close the inlet fan and exhaust disc valve . The electric heating is continuously opened and closed through PID control, and the box is in the heat preservation stage of hot air circulation. When the heat preservation time reaches the set value, the time relay outputs a signal to the PLC, and the PLC outputs a fully closed electric heating. The water cooling solenoid valve is opened to make it close and conduct, so that the box is in the cooling stage. The temperature control of the box adopts the GCD-23A intelligent computer temperature control and PLC automatic control system. The temperature signal is collected by platinum resistance. The PID control signal is obtained after the amplification of the temperature controller and the set value, and the PLC program controller outputs at the same time The control signal controls the solid-state relay SSR to turn on, and the solid-state relay controls the heater to heat, so that the cabinet is in the heating and dehumidifying stage.
