Asphalt rotary film oven

Working principle and structure:

1. The main body is made of thin steel plate, with the upper part being the working chamber, the lower part being the electrical control part, and the rear being the mechanical rotating device. The shell is coated with electrostatic spray paint.

2. The oven door is equipped with double-layer heat-resistant glass windows, which can observe the internal test situation of the oven. There are ventilation holes at the bottom and top of the oven, and there is a ventilation space between the oven and the inner wall. A squirrel cage fan is installed at the midpoint of the top of the oven and driven to rotate by a motor. There is a ring-shaped metal frame on the rear wall of the oven, which can lock and open 8 glass bottles. The air nozzle at the bottom is connected to an air flow meter.

3. This product's temperature controller adopts fuzzy control theory and traditional PID method to control the temperature smoothly. The advanced no overshoot self-tuning scheme greatly improves the temperature fluctuation performance. When the instrument is powered on, turn on the power switch, set the required working temperature, adjust the time relay, and then turn on the heating rotation, gas supply, fan, and switch in sequence. When the working room reaches the set temperature, the temperature control instrument automatically stops heating. When the working room is below the set temperature, the temperature control instrument automatically heats up until the set time.
