Abstract

PURPOSE:To reduce the ratio of heat taken out by an exhaust gas to the total load and reduce heat loss, by a method wherein the rotating speed of an exhaust fan can be freely set in accordance with drying and baking conditions corresponding to the material to be dried, and exhaust gas quantity is controlled. CONSTITUTION:A frequency convertor 14 is operated in accordance with the kind and quantity of a coating material to select the frequency of electric power supplied, and the rotating speed of the exhaust fan 16 is determined. When the drying furnace is started, the rotating speed of the fan 16 is low until the atmosphere in the furnace attains an operating temperature, and when a predetermined operating temperature is reached, the rotating speed of a driving motor 12 for the fan 16 is enhanced through a temperature sensor. Namely the rotating speed of the motor 12 at the time of raising the temperature in the furnace is set to be about 1/3-1/6 times of that at the time of the drying operation, and when the vapor of a solvent contained in the coating material starts to be generated in the drying operation, the rotating speed of the fan 16 is raised through a temperature sensor.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an exhaust amount control device for a paint baking and drying oven, which controls the exhaust amount by controlling the rotation of an exhaust fan.

The amount of heat in the drying oven used for baking and drying after applying a base coat to a metal plate is extremely large, and the amount of solvent vapor during painting is also large, causing the furnace to be filled with solvent vapor O. In order to prevent this from occurring, the atmosphere inside the furnace was brought out of the furnace by an exhaust fan, and the rotational speed of the exhaust fan was kept constant to ensure a constant exhaust volume.

However, during the heat load of the drying oven, the rate of removal by exhaust gas is extremely large, reaching 70% to 80% of the heat load.

The loss of heat due to such exhaust gas is alleviated. Conventionally, there have been methods for exhausting the air inside the drying oven by opening a damper that is controlled by an electromagnetic switch with a timer, and a method for rotating and stopping an exhaust fan using an electromagnetic switch with a timer. In both cases, the damper is opened and closed, and the exhaust fan is rotated and stopped, regardless of the type of paint or the amount of paint used, so not only does the operating rate drop by 1,000, but it also takes too much time to adjust the exhaust m. However, it was not possible to achieve the desired effect.
