A seal chamber is formed, and air blowing means is provided for each of the seal chambers. The other configurations are the same as those in the first embodiment, and the description will be repeated. The same components as those in the embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.
[0019]
In the second embodiment, partition walls 25a and 25b are formed outside the carry-in side spray seal chamber 7 and the carry-out side spray seal chamber 9 in the spray processing device 21, and the carry-in side air seal is formed. A chamber 23 and a carry-out side air seal chamber 24 are formed.
[0020]
Air blowing means 22a and 22b are provided in the carry-in side air seal chamber 23 and the carry-out side air seal chamber 24, respectively, and the air blow means 22a and 22b are respectively provided in the main spray processing chamber 8 side, that is, in the spray processing. It is arranged at a predetermined angle inward of the device 21.
[0021]
As described above, the spray processing means 12a and 12c provided in the carry-in side spray seal chamber 7 and the carry-out side spray seal chamber 9 are respectively arranged to be inclined toward the main spray processing chamber 8, and the carry-in side air seal is provided. The air spraying means 22a and 22b provided in the chamber 23 and the carry-out side air seal chamber 24 are also arranged to be inclined toward the main spray processing chamber 8, respectively, so that the sprays of the spray processing means 12a and 12c are mainly provided. The spray is sprayed to the spray processing chamber 8 side, and the spray works as a spray seal, and the air blown from the air blowing means 22a, 22b to the main spray processing chamber 8 also works as an air seal, so that the spray processing means 12a, 12b, Leakage of the processing liquid sprayed from 12c to the outside of the spray processing apparatus 21 More can be further reduced, also, it is not necessary to dispose the partition, it's not that the plate-like member 3 to be sprayed hurt.
[0022]
The air blown from the air blowing means 22a and 22b may blow air outside the spray processing device 21 by, for example, a blower 26 or the like, but as shown in FIG. 23, and the air in the carry-out side air seal chamber 24, or the air in the carry-in side spray seal chamber 7, the carry-out side spray seal chamber 9, the carry-in side air seal chamber 23, and the carry-out side air seal chamber 24 are sucked. The mist contained in the air is separated by a mist separator 27, and the air separated from the mist is sent to the air blowing means 22a, 22b by a blower 26 or the like, and is blown out from the air blowing means 22a, 22b to circulate. Preferably.
[0023]
By circulating the air inside the spray processing device 21 in this manner, the amount of air discharged from the spray processing device 21 is reduced, and thus the air in the room where the spray processing device 21 is installed is reduced. You can.
[0024]
【The invention's effect】
