Abstract
The utility model discloses a temperature precise control system of a water tank-type tobacco stem moisture regaining device. A first electrical valve locator is arranged on a second pneumatic diaphragm valve. A third stop valve is mounted on the front end of a third pneumatic diaphragm valve. A first pneumatic diaphragm valve is additionally equipped with a second electrical valve locator. A drain valve is connected in parallel with a fourth stop valve. Signal input terminals of the first and second electrical valve locators are respectively connected with signal output terminals of a control module. Signal output terminals of a temperature sensor and a liquid level sensor are respectively connected with signal input terminals of the control module. The temperature precise control system utilizes the temperature sensor arranged in an original control system to acquire temperature information and the temperature information is transmitted to a PLC for analyzing and processing. The PLC utilizes the first and second electrical valve locators to conduct PID control of the level and temperature of water inside a water tank, thereby realizing precise closed-loop control of the level and temperature of the water, reducing water temperature fluctuations, and stabilizing the temperature and moisture content of outlet materials. The temperature precise control system is simple in structure and easy to implement.
