As described above, the dirt (washing residue) peeled off and separated from the workpiece flows into the washing residue accumulation box 5 together with the high-pressure washing water and the rinsing water via the funnel-shaped guide frame 12 formed in a funnel shape. And can be temporarily stored. At this time, falling water is supplied to the funnel-shaped guide frame 12 formed in a funnel shape from the slag removing water supply passage Ls so that dirt does not remain on the way. In the above-described cleaning process, high-pressure cleaning water is applied to the work to perform cleaning, and accordingly, a corresponding noise is generated. However, a rubber-made space between the lower portion of the transport guide roller 3 and the cleaning residue accumulation box 5 is formed. The above-mentioned noise can be reduced by surrounding by the funnel-shaped guide frame 12.

When dirt accumulates together with high-pressure washing water, rinsing water and flowing water in the washing residue accumulation box 5, the dirt accumulates from its own weight on the bottom plate 17 side. Only the washing water or the like is discharged to the outside through the overflow pipe 27 on the upper end side of the side plate 16.
In the overflow pipe 27, light dirt floating in the washing water can be filtered out by a filter.

When the dirt accumulates up to the upper end of the side plate 16 of the cleaning residue accumulation box 5, the cleaning operation is stopped and the claws of the forklift are moved between the hollow square frames 22, 22 of the bottom plate 17 of the cleaning residue accumulation box 5. The cleaning residue accumulation box 5 is taken out of the cleaning device 1 via the guide passage 25 in a state where the cleaning residue is inserted and lifted (see FIG. 6).
At this time, the guide casters 24a to 24d in the vicinity of the bottom plate 17 of the side plate 16 can smoothly pass through the guide passage 25, and the cleaning residue accumulation box 5 can be easily formed.
Can be taken out. Then, the washing residue accumulation box 5 is lifted through the fork claws 29 of the forklift 28 on the hooks 26a to 26d of the side plate 16, and brought above the industrial waste box 30 provided in advance.
By pulling out the locking bolts 20, 20 for stopping the bottom plate 17,
The bottom plate 17 is opened downward with the hinge 18 as the center of rotation, and can discharge the deposit of the cleaning residue (see FIG. 8). In this manner, the water provided for cleaning is once accumulated together with the dirt in the cleaning slag accumulation box 5, the cleaning water and the dirt are separated, only the water is first drained, and the dirt is deposited.
Since the waste is stored in the industrial waste box 30, there is no risk of environmental pollution or the like due to runoff.

[0020]

As described above, according to the present invention, noise is suppressed by using a large amount of washing water, and pollution is prevented by pouring the dirt with the dirt that has been peeled off and washed outside. Can also contribute.
