ABSTRACT

This paper introduces the temperature control system based on PLC baking room, and now the temperature control system is widely used in the field of industrial control.

Paint room is generally used for spraying and baking paint, therefore, the most accurate description of the paint room should be \paint room\General paint spray when the object surface treatment, clean dust.

When painting, the external air is filtered through the primary filter screen, then sent to the roof by the fan, and then filtered into the room after the two filtration. Room air using a full drop type, the flow rate down to 0.2-0.3m/s, so that the paint spray paint particles can not stay in the air, and directly through the bottom of the outlet is discharged outside the room. This constant cycle conversion, make painting room air cleanliness reached above 98%, and into the air with a certain pressure, but a constant flow formed in the car around to remove excess paint, so as to maximize the quality of paint.

Baking paint, the air door to the paint position, hot air circulation, baking room temperature rapidly increased to a predetermined drying temperature (55 C - 60 C). Fan outside fresh air early after filtration, gas chamber heat exchange is sent to the roof with baking heat energy converter, and then after second times of filtration and purification, hot air after air circulation within the role, in addition to small amounts of fresh air, most of the hot air and continue to be heated by the temperature gradually increased, paint room in. When the temperature reaches the set temperature, the burner automatically stops; when the temperature drops to the set temperature, the fan and the burner are automatically opened, so that the temperature of the baking room is kept relatively constant. Finally, when the baking time reaches the set time, the paint room will automatically shut down.
