Description

[Detailed explanation of the idea] The present invention relates to a spray paint processing device.

Conventionally, in spray painting, as shown in Fig. 1, excess paint mist a of the spray paint is deposited on the rear wall 2 of the object to be painted 1, and then washed off with water to the underside of the floor and coagulated and precipitated. That process had already been done. However, according to this method, there were problems such as high costs for water treatment and paint sludge treatment, and further problems such as atmospheric evaporation of paint mist.

The present invention provides a spray paint processing apparatus that can solve the above problems, and one embodiment thereof will be described below with reference to the drawings.

In FIG. 2, reference numeral 11 denotes a painting room, and 12 denotes an object to be painted, which is transported within the painting room 11 by a hanging transport device 13 and is sprayed with paint by a spray gun 14. Reference numeral 15 denotes a belt conveyor-type collecting body for excess paint mist b provided behind the object to be painted 12, which moves the excess paint mist b from the coating chamber 11 into the combustion chamber 16 above the coating chamber 11. That is, the belt 17 that collects the excess paint mist b is connected to the drive path roller 18 located at the lower part of the painting chamber 11 and the combustion exhaust gas duct 19 located above the combustion chamber 16.
It is wound endlessly around the driven roller 20 located inside and is movable in the direction of arrow c. As shown in FIGS. 3 and 4, the belt 17 has a ceramic filter 22 adhered to its entire surface via a plurality of belt members 21. A combustion burner 23 is provided within the combustion chamber 16 and is provided facing the belt 17.
Reference numeral 24 denotes a painting chamber duct formed behind the collector 15, whose lower end communicates with the interior of the painting chamber 11, and whose upper end communicates with the combustion exhaust gas duct 19 via an exhaust fan 25. Note that 26 is a buffer plate provided in the duct 24 in the painting room, and 27 is a paint mist collection part provided at the bottom of the painting room 11.

According to the above configuration, when spray painting the object 12 with the spray gun 14, most of the excess paint mist b is collected by the belt 17 of the collector 15, that is, by the ceramic filter 22, and is collected in the combustion chamber 1.
Moved within 6. Then, by utilizing the thermal properties of ceramic, the paint mist collected in the porous portion 22a of the ceramic filter 22 is burned in a combustion burner 23. As described above, the ceramic filter 22 treated by the combustion burner 23 is moved downward with appropriate air cooling and is used again for circulation to collect the paint mist b. Incidentally, there are cases in which water-soluble paints and solvent-based paints are used, and in the latter case, the installation position of the combustion burner must be changed to prevent fire.

As described above, according to the present invention, excess sprayed paint mist is collected on the ceramic filter and burnt using a combustion burner, eliminating the need for conventional water treatment and eliminating the need for conventional water treatment. As a result, paint mist treatment costs can be significantly reduced, and since the paint mist is burned, it is also effective as a countermeasure against odors.
