Description

Painting product dryer

The present invention relates to an apparatus for drying a paint, and more particularly, to increase heat efficiency of a booth and various paints, regardless of the number or area of a drying object moving along a belt at a predetermined interval, to complete a car or various paints. The present invention relates to a painting product drying apparatus for drying a product.

As a general coating booth, a dry baffle coating booth is known. The baffle-type paint booth is formed in a rectangular box shape with the front open, and a baffle plate serving as a first filter is placed upright inside the box-shaped booth body, and is formed behind the baffle plate. Two filters are disposed, and an exhaust chamber is formed behind the second filter. Furthermore, an exhaust blower is attached to the upper part of the exhaust chamber, and the air in the booth body is exhausted through the exhaust chamber, the baffle plate, and the second filter by the exhaust operation of the exhaust blower.

When painting by spraying paint from a spray gun in the booth body, the paint mist sprayed from the spray paint gun and dissipated in the booth body is baffle plate (first filter) and second filter. Suction through

By collecting the paint mist, the spray mist is prevented from scattering. In the conventional paint booth, a vortex chamber is provided in the booth, the vortex is generated in the exhaust gas from the vortex chamber, the air and the paint mist are separated by the vortex, and the paint mist is separated into the water tank. There is a venturi type booth.

And as another form, the oil circulation type coating booth is also known.

By the way, painting work is always performed with sheet metal work, such as an outer panel of an automobile, for example. As the size of the panel on which the painting is performed, one to two work panels occupy 70 to 80% of the total.

After the painting work is performed in the painting booth, a drying apparatus for drying the painted paint within a short time is installed.

Conventionally, a drying apparatus installed in a painting booth adopts a hot air drying method using a hot air boiler mainly using oil as a fuel.

In the conventional hot air drying method as described above, there is a heat-drying drying method in which heated hot air is supplied into a paint booth to directly dry paint by directly contacting paint coated on a car by hot air convection.

The hot air drying method has low heat efficiency due to high heat loss, and the temperature distribution due to convection action is not constant, so that the paint coated on the body of the car is not uniformly dried, resulting in long drying time and pinhole phenomenon. There was a problem.

In addition, it has been pointed out that the longer the drying time, the longer the operation time of the hot air boiler is, and the more fuel is required, thereby increasing the operating cost of the drying apparatus of the coating booth.

According to the inventor of the present invention as a solution for solving the problems in the hot air welding method using the hot air boiler as described above

The paint drying device using a far-infrared heater (halogen lamp) of Utility Model Registration No. 386028 has been proposed, and the far-infrared heater paint drying apparatus is more efficient in terms of thermal efficiency and operating cost than drying equipment using a hot air boiler. It provides excellent advantages, but not only the deterioration of the coating quality can be caused by the residue of fine dust generated during painting, but also the risk of fire due to the combustible gas flowing in the booth and the evaporation gas generated during painting drying. There was a problem.

In addition, automotive paints (paints) are usually used by diluting the diluent in an appropriate ratio and diluting it with an easy to spray viscosity. Before starting the drying operation after the painting work in the bundling, the infrared heater must be operated after removing the thinner gas remaining in the booth. In the prior art, the paint drying booth using the infrared heater convections the air in the booth. Since only a circulation fan is installed to circulate the gas inside, there is no device to discharge residual gas inside the booth.Therefore, a fire due to residual gas may occur when the infrared heater is operated to perform the drying operation. In the process of drying the paint on the car body If the generated evaporated gas is not removed and accumulates in the booth, it is pointed out that a problem of explosion may be greater than a fire.

Painting of the vehicle is carried out by spraying a paint of a desired color is deposited by coating the paint on the outer surface of the vehicle body and then drying it.

In addition, in the drying booth in which the painted and dried products consist of single parts and move along the conveyor belt, even if heat is irradiated from the upper and left and right sides, drying of the drying object located inside is not performed smoothly, and both ends of the booth are opened so that the heat loss is reduced. There was a problem that occurred.

For this reason, it is possible to maintain a uniform coating quality due to the uniform heat transfer over the entire area of the object to be dried, and there is an urgent need for a coating and drying apparatus that minimizes the hand of heat at both ends of the booth.
