[Industrial applications]

 The present invention relates to an automatic device for collecting paint mist in a washing booth for painting.

[0002]

[Prior art]

 In the case of continuous coating such as industrial coating, dry bose is not suitable for large-scale coating because the baffle plate is cleaned and the filter is frequently replaced due to dirt. There is a water washing booth as a means for solving such a problem. The known washing booth has the characteristics as shown in FIG. (B) The paint mist hits the water screen 1, mixes with the water film, and falls into the water tank 2. (B) The air in the coating booth 4 is passed through the lower part of the water screen 1 by the axial fan 3, passes through the water drop layer of the spray shower nozzle 5, passes through the eliminator 6, and is discharged to the outside through the duct 7. The paint mist and solvent gas are mixed in the air and are not completely adsorbed by the water film of the water screen 1, but are sprayed into the water tank 2 by the spray shower nozzle 5.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned water-washing booth, most of the paint mist is dropped into the lower water tank 2 by the water screen 1 and the spray shower nozzle 5 provided at the front of the booth, and the water mist as floating matter or sediment 2 accumulates on the inner bottom portion 2a of the coating 2 and is used continuously for a long time, the paint mist solidifies, so it is necessary to remove it from the water tank 2.

As the removing means, conventionally, the upper lid portion 8 of the water tank 2 is cleaved and the paint mist stuck to the inner bottom portion 2a of the water tank 2 is scraped off with a scoop or the like. However, such a removing means is inefficient because it is a manual method, and because it opens the upper lid portion 8, it gives off a bad odor and is not preferable in the working environment.

[Means for Solving the Problems]

 The present invention relates to an automatic method for collecting paint mist in a washing booth for painting. More specifically, the present invention relates to a washing booth including a water screen 12, a spray shower nozzle 13, an eliminator 14, an exhaust fan 15, and a water tank 16. By the operation of the paint mist spiral feeding mechanism 17 installed in the water tank 16, the paint mist that adheres to the inner bottom of the water tank 16 and is solidified is crushed and fed, and the spiral feeding mechanism 17 is operated. The paint mist in the water tank 16 that is crushed and fed is fed to the paint mist collecting hopper 21 and the recovery box 22 through the conveying means of the automatic conveying mechanism 28 outside the coating booth attached to the water tank 16. In the recovery box 22, the paint mist is separated into water and sludge, and the sludge is stored in the recovery box 22. An automatic recovery device of the paint mist that put the paint washing booth, characterized in that water to the water yield Bokkkusu 22 pump 23 and water pipe 24 in the water tank 16 of the washing booth through.

[0006]

[Action]

 The paint mist that hits the water screen 12 installed in the front of the washing booth 11 mixes with the water film and falls into the water tank 16. The paint mist that was dropped into the water tank 16 by the water screen 12 and the spray shower nozzle 13 and accumulated on the inner bottom portion 16a of the water tank 16 and solidified during long-term use was fed into the main tank 16b of the water tank 16 and fed out. And the crushing action are co-operated by the operation of the spiral feeding mechanism 17, which is temporarily treated and continuously fed into the auxiliary tank 16b juxtaposed to the main tank 16a so as to be collected collectively. Via an automatic transfer mechanism such as an external first automatic transfer mechanism 18 that connects the paint mist extruded from the auxiliary tank 16b to the auxiliary tank 16b, an external second automatic transfer mechanism 19 and an external third automatic transfer mechanism 20. The paint mist collecting hopper 21 to the recovery box 22, and in the collection box 22, the paint mist is separated into water and sludge, and the sludge is collected in the collection box 22. It is the reservoir, to allow circulation reused by returning the water in the collecting box 22 through the pump 23 and water pipe 24 into the water tank 16 of the washing booth 11.

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS. 2 is an overall structural view of an apparatus embodying the method of the present invention, FIG. 3 is a structural view of a water tank in the apparatus, and FIG. 4 is a structural view of an external automatic transfer mechanism section.

FIG. 11 shows a washing booth, and the booth 11 is roughly constituted by a water screen 12, a spray shower nozzle 13, an eliminator 14, an exhaust fan 15, a water tank 16 and the like.

The water tank 16 is divided into two chambers, a main tank 16a and an auxiliary tank 16b. Inside the water tank 16, a paint mist spiral feeding mechanism 17 is installed. That is, as shown in FIG. 3, the spiral feeding mechanism 17 includes a plurality of shaft portions 25 provided over the water tank 16, a spiral body 26 in which blades are spirally wound around the plurality of shaft portions 25, The water tank 16 is composed of a plurality of shaft portions 25 and a gear transmission mechanism 27 for transmitting rotational movement to the spiral body 26.
