Description of the Related Art Conventionally, as shown in FIG. 4, when a paint is sprayed on a work A in a paint booth 1 comprising a paint section 1a and a washing section 1b, a part of the paint adheres to the work A. However, others adhere to the grating 2 of the work floor of the coating section 1a or the water film plate 3 of the washing section 1b, or are captured by the washing water in the washing section 1b and dispersed in water.

ことによって回収できる。[0003] Relatively fine paint particles (10 to 50 microns in diameter) dispersed in the washing water easily float in the washing water by the water flow or by the stirring water flow when a slow stirring machine is installed. The paint particles dispersed and suspended in the washing water can be recovered by filtration with a centrifuge or a filter.

The paint adhered to the surface is deformed into a string shape due to the creep phenomenon with the passage of time, and part of the paint adheres to the washing section 1 of the washing booth 1.
b. The paint that does not fall is removed by cleaning by periodic work, or the grating 2 is temporarily removed, and the attached paint is saponified in a high-temperature alkaline solution to make it easy to peel off, and then removed. Thus, the grating 2 is installed in the painting booth 1 again.

る。In recent years, the use of a high-pressure washing machine has been becoming popular in order to save labor in these operations. In this case, a high-pressure washing machine is used with the grating 2 installed on the work floor of the painting booth 1. Is peeled off. The peeled paint residue falls on the water film plate 3 of the washing section 1b, and then precipitates in a portion of the washing paint booth where water stays. Further, the paint adhered to the water film plate 3 is also peeled off from the water film plate by periodic cleaning, and settles in the washing water in the same manner as described above.

粕を定期的に清掃して除去することが必要である。[0006] These settled paint cakes produce butyric acid and propionic acid by anaerobic fermentation in about one week, causing malodor. Further, when the precipitation is remarkable, the water flow in the apparatus is hindered, and the washing efficiency in the washing section is lowered. Therefore, it is necessary to periodically clean and remove paint residue.

る。Conventionally, in order to remove settled paint residue (diameter 1 to 5 mm) having a relatively large size, the washing water is drained from the washing water circulation tank 8 periodically (every one week to three months) and then cleaned. Was made. When draining the washing water, a replacement tank 19 for temporarily transferring the washing water was provided. However, in recent years, these cleaning operations are unsafe and unsanitary in the working environment, and it is becoming difficult to secure workers.
